Today I will introduce you to a national invention authorized patent-a camera-reading gas meter that is easy to adjust the level. The patent was applied by Chengdu Hi-Tech Co., Ltd. and was authorized to be announced on May 8, 2018.
Description of contentThe invention relates to the technical field of gas meters, and in particular, to a direct-reading gas meter with camera for easy adjustment of the level.
Background of the inventionWith the improvement of living standards and the enhancement of environmental awareness, natural gas has become an important energy supply. In the natural gas supply system, the gas meter has an important role. It automatically records the amount of gas used by the user. The smart gas meter can also be used for remote meter reading. The gas number used by the user can be read without entering the user's home. The popularization and application of smart gas meters has solved the drawbacks caused by the need for door-to-door meter reading in the gas management industry.
However, according to the regulations of the gas company on the installation location of the gas meter, the gas meter can only be placed horizontally on the bracket without tilting, and the vertical deviation of the gas meter should be less than 10 mm. Tools, the vertical deviation of the gas meter is difficult to be guaranteed. Furthermore, due to the user replacing the battery and inserting and removing the IC card, or the gas meter is installed for too long, the connection will be loosened, which will cause the vertical deviation of the gas meter to change. The gas counting device cannot count normally.
Chinese patent CN203349882U discloses a gas meter with a spirit level. The gas meter body includes an upper case and a lower case. The gas meter body is provided with a spirit level. The lower case is provided with a groove embedded in the spirit level. The top of the lower shell and the bottom of the lower shell are also provided with a bracket for supporting and fixing the gas meter. During installation and use, it can intuitively reflect its own inclination, which is convenient for the operator to adjust its level, and the installation is stable , Firm.
Although the solution in the above patent can facilitate the operator to adjust the level during the installation process, in use, the gas meter or even the bracket may be skewed. At this time, the adjustment requires adjustment of the entire bracket, which is equivalent to reinstalling and using Very inconvenient. Especially for gas meters directly read by camera, if the gas meter is skewed, it may also affect the image acquisition of the image sensor.
Summary of the inventionThe purpose of the present invention is to provide a direct-reading gas meter with camera for easy level adjustment. The gas meter body is provided with a spirit level, and its supporting frame can not only directly reflect its own tilt status during installation and use, but also adjust gas. When the watch body is level, it is only necessary to adjust part of the support frame, without adjusting the entire support frame, and adjustment is very simple.
Figure is a schematic diagram of the structure of the present invention
The technical solution adopted by the present invention to solve the above-mentioned problems is: a direct-reading gas meter for camera that is convenient for adjusting the level, including a gas meter body, a level meter is provided at the top of the gas meter body, and a support frame is also included; the support frame includes a lower bracket, Upper bracket, adjusting bolt; lower bracket includes horizontally arranged lower supporting plate, vertically arranged lower fixing plate and multiple supporting rods, the lower supporting plate is fixedly connected to the upper end of the lower fixing plate, one end of the supporting rod is fixed to the lower supporting plate, The other end is fixed on the lower fixing plate; the upper bracket includes a horizontally arranged upper pallet and a vertically arranged upper fixed plate, the upper pallet is set on the lower pallet, the lower end of the upper fixed plate is fixed on the upper pallet; the upper fixed plate The back of the lower fixing plate, the lower support plate and the upper support plate are on the same plane; the adjustment bolt is set on the upper support plate, and the lower end of the adjustment bolt is in contact with the upper end surface of the lower support plate; the front of the upper fixing plate is also provided with a rectangular space Cavity, the gas meter body is installed in a rectangular cavity. In this solution, the support frame is composed of two upper and lower brackets. The two brackets are split structures. An adjustment bolt is installed on the upper bracket. The lower end of the adjustment bolt contacts the lower bracket. The gas meter is installed on the upper bracket. During installation and use, when the gas meter is observed to be tilted through the level, the height of the adjustment bolt can be adjusted to adjust the position of a side or a corner of the upper bracket to ensure the level of the gas meter installed on the upper bracket When adjusting the level, you only need to adjust the adjustment bolts. There is no need to operate the upper bracket, the lower bracket or even the gas meter. The adjustment is very simple and convenient, and does not require professional tools and professional skills.
As a further improvement of the present invention, the support frame further includes a height adjustment structure, the height adjustment mechanism includes a gear, a connecting rod and a handle, and a second cavity for mounting a gear and a through hole for mounting the connecting rod are also provided on the upper fixing plate, Part of the teeth of the gear extend from the second cavity to the rectangular cavity; the axis of the through hole is parallel to the plane where the upper fixing plate is located, one end of the connecting rod is connected to the center of the gear, and the other end extends out of the upper fixing plate to connect the handle; The back of the gas meter body is provided with a plurality of clamping slots matching the clamping teeth of the gear, and the length direction of the clamping slots is consistent with the horizontal direction. In this solution, the height adjustment mechanism is added, on the one hand, it is convenient to install the gas meter body into the rectangular cavity with less effort when installing the gas meter body, and the lower end is in contact with the upper bracket; on the other hand, the adjustment bolt When adjustment is not possible, it is convenient to adjust the gas meter body up, and insert a gasket between the upper pallet and the gas meter body to keep the gas meter body level.
The upper pallet and the lower pallet are rectangular plates, and the number of adjusting bolts is four, which are respectively set on the four corners of the upper pallet. The height of the upper bracket can be controlled from four positions together. Convenience. An image sensor is arranged on the front of the gas meter body, and the image sensor is facing the dial of the gas meter body. In order to make the supporting rod better support the lower supporting plate and make the lower bracket more stable, the angle between the supporting rod and the lower supporting plate and the lower fixing plate is 45 °.
The beneficial effects of the present invention are: 1. The upper bracket and the lower bracket of the support frame of the present invention are split structures, and the tilt of the upper bracket can be adjusted by adjusting the adjustment bolts to ensure the level of the upper pallet, thereby ensuring The level of the gas meter body installed on the upper bracket; 2. The invention only needs to adjust the adjustment bolts when adjusting the level, no need to operate the upper bracket, the lower bracket or even the gas meter body, nor Professional tools and professional skills are very simple and convenient to adjust; 3. The invention also adds a height adjustment mechanism, on the one hand, it is convenient to install the gas meter body into the rectangular cavity with less effort from top to bottom when installing the gas meter body. The lower end is in contact with the upper pallet; on the other hand, when the adjustment bolt cannot be adjusted, it is convenient to adjust the gas meter body up, and insert a gasket between the upper pallet and the gas meter to keep the gas meter level.
