Description

Technical Field

[0001] The utility model relates to the technical field of gas meters, in particular to an auxiliary observation device for a gas meter with adjustable angle. Background Art

[0002] The gas meter auxiliary observation device with adjustable angle is an auxiliary tool designed for gas meters. Its main purpose is to facilitate users to read the gas meter value more accurately by adjusting the observation angle. The device usually includes an adjustable angle bracket and a clamping part for fixing the gas meter. The bracket part adopts a rotatable or retractable design, so that users can easily adjust the angle of the device according to the installation position of the gas meter and their own observation needs. The clamping part is responsible for firmly fixing the gas meter to ensure that the gas meter remains stable and will not move or shake during the angle adjustment process. The auxiliary observation device is very easy to use. Users only need to fix the device on the gas meter, and then adjust the angle of the bracket as needed to easily read the value of the gas meter. This greatly improves the accuracy and convenience of observation, especially for gas meters with poor installation positions or limited observation angles. The adjustable angle gas meter auxiliary observation device usually also has good durability and stability, and can adapt to various environments and usage conditions.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1: This embodiment is intended to promote the solution of the problem in the prior art that when the gas pipe 110 is used, the gas meter is mostly installed on the connecting pipe 130. If the connecting pipe 130 is connected to the gas pipe 110 by direct engagement, it is inconvenient to disassemble the connecting pipe 130 or the gas meter when it is used for a long time. Figure 1-Figure 7 A gas meter auxiliary observation device with adjustable angle includes a gas pipe 110, a connecting pipe 130 is installed in the middle of the gas pipe 110 through a fixing component 350, a gas meter body 140 is installed at the end of the connecting pipe 130, a fixing plate 120 is installed on the side of the gas pipe 110, a supporting frame 150 is fixedly installed on the side of the fixing plate 120, and an observation meter 180 is installed on the side of the supporting frame 150.

[0027] A mounting hole 200 is provided in the middle of the support frame 150, and a rotating rod 190 is inserted in the middle of the mounting hole 200. A fixing rod 160 is fixedly connected to one end of the rotating rod 190, and a mounting rod 170 is fixedly installed on the other end of the rotating rod 190. The observation meter 180 is installed on the side of the mounting rod 170. A clamping rod 390 is fixedly connected to the bottom of the support frame 150, and a clamping groove 400 is provided at the end of the clamping rod 390. A rolling groove 420 is provided in the middle of the rotating rod 190, and a mounting ring 380 is installed in the middle of the rolling groove 420. The mounting ring 380 is configured as a rubber ring. A ball 410 rolls in the middle of the rolling groove 420, and the ball 410 is clamped and connected to the clamping groove 400. The fixing component 350 includes an air outlet groove 230 provided on the side of the gas pipe 110. The side of the air outlet groove 230 is connected to a limiting groove 240. There are several limiting grooves 240 in a circular array, and the side of the air outlet groove 230 is connected to a connecting groove 250.

[0028] When the observation meter 180 needs to be adjusted, the staff can just rotate the fixing rod 160. When the fixing rod 160 rotates, since the mounting ring 380 is installed in the middle of the rotating rod 190, the mounting ring 380 will be squeezed during the rotation process, causing the mounting ring 380 to deform. When the mounting ring 380 is deformed, the observation meter 180 will not move due to the limitation of the rubber ring unless the staff applies force, so that the staff can observe easily.

[0029] When it is necessary to install the connecting pipe 130, the staff first inserts the connecting pipe 130 into the gas pipe 110, and then makes the limiting rod 220 engage with the limiting groove 240. During the connection process, the spring 330 in the engaging assembly 360 is squeezed by the gas pipe 110 and will shrink. Then, when the engaging assembly 360 is completely engaged with the fixing groove 260, the spring 330 will be released when there is no external force, and will engage with the fixing groove 260. When disassembly is required, the staff can directly pull out the connecting pipe 130. When pulling it out, the spring 330 is squeezed by force and passes through the connecting groove 250 smoothly. Then, the connecting pipe 130 can be replaced or the gas meter body 140 can be maintained or replaced.

[0030] In this embodiment: by installing the fixing component 350, when installing between the gas pipe 110 and the connecting pipe 130, the installation can be made as firm as possible. By installing the snap-fit ​​component 360, when installing and disassembling the connecting pipe 130, the snap-fit ​​component 360 can be cooperated to make the installation and disassembly as convenient as possible, thereby solving the problem that most of the gas meters mentioned in the above background technology are installed on the connecting pipe 130. If the connecting pipe 130 is connected to the gas pipe 110 by direct snap-fitting, then during long-term use, if the connecting pipe 130 or the gas meter fails, it is inconvenient to disassemble, thereby making it more convenient for the staff to operate.

[0031] Embodiment 2: This embodiment is intended to promote the solution of the problem in the prior art that if the installation is not in place, there is a high possibility of air leakage. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 7 The side of the connecting groove 250 is connected to the fixing groove 260, and a clamping block 270 is installed in the middle of the fixing groove 260. There are several connecting grooves 250, fixing grooves 260, and clamping blocks 270 in a circular array.

[0032] A circulation pipe 210 is inserted in the middle of the air outlet groove 230, and a fixing plate 290 is fixedly installed on the side of the circulation pipe 210. A connecting plate 280 is fixedly connected to the side of the fixing plate 290, and a clamping assembly 360 is fixedly connected to the side of the connecting plate 280. The clamping assembly 360 includes a reinforcing rod 370 that is clamped in the middle of the fixing groove 260, and a clamping rod 300 is installed on the side of the reinforcing rod 370. The middle of the clamping rod 300 is provided with a mounting groove 320.

[0033] A spring 330 is installed in the middle of the installation groove 320, one end of the spring 330 is fixedly connected to a contact plate 340, the contact plate 340 is fixedly installed to the reinforcement rod 370, the other end of the spring 330 is fixedly connected to a connecting plate 310, the connecting plate 310 is in contact with the inner wall of the fixed groove 260, a limiting rod 220 is fixedly installed on the side of the circulation tube 210, the limiting rod 220 is snap-fitted and connected to the limiting groove 240, a plurality of fixing plates 290, connecting plates 280, limiting rods 220, reinforcement rods 370 and snap-fitting rods 300 are arranged in a ring array.

[0034] In this embodiment: through the setting of the snap-fit ​​assembly 360, when installing the connecting pipe 130, the staff first snaps the limit rod 220 into the limit groove 240. During the connection process, the spring 330 in the snap-fit ​​assembly 360 will be squeezed due to the action of external force, so that the reinforcement rod 370 and the fixed groove 260 can be snap-fitted and connected. Then, when there is no external force, the spring 330 will be released, and then the snap-fit ​​rod 300 will be snap-fitted with the fixed groove 260 more firmly, making the installation more convenient.
