Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas meter technology, and in particular to a gas meter sampling plate. Background Technology
[0002] The gas meter sampling panel is commonly referred to as a gas meter testing panel or gas meter calibration panel. Its main function is to monitor and collect data on the metering performance of the gas meter, ensuring the accuracy, stability, and safety of the gas meter.
[0003] In the actual use of gas meters, the sampling plate is usually connected to the gas meter body through an interface to ensure the smooth flow of gas. However, the sampling plate interface in existing gas meter designs usually uses a threaded connection to achieve physical connection with the gas meter. Although threaded connections are convenient to install, their sealing performance is often insufficient. Specifically, since threaded connections rely on the friction between the threads to achieve a seal, in long-term use, the threaded connection may become incompletely sealed due to factors such as wear, deformation, changes in ambient temperature, or uneven tightening during installation, forming tiny leakage channels. Utility Model Content
[0004] The purpose of this invention is to solve the problem that the existing technology uses a threaded connection to achieve physical connection with the gas meter. Although the threaded connection is convenient to install, its sealing performance is often insufficient.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gas meter sampling disc, comprising a sampling disc body, a sampling pipe fixedly embedded at the top center of the sampling disc body, a connecting pipe fixedly embedded inside the sampling pipe, a threaded groove provided on the outer surface of the connecting pipe, a first sealing gasket fixedly installed on the top of the sampling pipe, the first sealing gasket fixedly sleeved on the outer surface of the connecting pipe, a first sliding groove provided on both sides of the outer surface of the sampling pipe, a slider slidably connected to the inner surface of the two first sliding grooves, a sleeve fixedly installed on the outer side of the two sliders, the sleeve slidably connected to the outer surface of the sampling pipe, and a support frame fixedly installed on the top of the sampling disc body.
[0006] In a preferred embodiment, a second sealing gasket is fixedly installed on the inner surface of the sleeve, and the second sealing gasket is movably sleeved on the outer surface of the sampling pipe.
[0007] The technical effect of adopting the above-mentioned further solution is that the second sealing gasket can be moved by the sleeve.
[0008] In a preferred embodiment, bolts are threaded to both sides of the sleeve, and a positioning groove is provided at the center of the support frame.
[0009] The technical effect of adopting the above-mentioned further solution is that the bolt can be rotated so that one end of it fits against the outer surface of the gas meter pipe, thereby fixing the sleeve.
[0010] In a preferred embodiment, the support frame has a second sliding groove on both sides of its top, and a clamp is slidably connected to the inner surface of each of the two second sliding grooves.
[0011] The technical effect of adopting the above-mentioned further solution is that it allows the clamping plate to slide through the second slide groove.
[0012] In a preferred embodiment, telescopic rods are fixedly installed on the outer sides of both clamps, and support plates are fixedly installed on the other ends of both telescopic rods.
[0013] The technical effect of adopting the above-mentioned further solution is that the telescopic rod can be squeezed by the clamping plate.
[0014] In a preferred embodiment, the bottoms of both support plates are fixedly installed on the top of the support frame, and rubber pads are fixedly installed on the opposite sides of both clamps.
[0015] The technical effect of adopting the above-mentioned further solution is that the rubber pad can be moved by the clamp.
[0016] In a preferred embodiment, a return spring is fixedly installed on the outer side of each of the two clamping plates, and the inner surface of each return spring is movably sleeved on the outer surface of the telescopic rod.
[0017] The technical effect of adopting the above-mentioned further solution is that the reset spring can be squeezed by the clamping plate.
[0018] In a preferred embodiment, the other ends of both return springs are fixedly mounted on the inner side of the support plate.
[0019] The technical effect of adopting the above-mentioned further solution is that the clamping plate can be used to reset the return spring and the telescopic rod. When it is resetting, it will push the clamping plate to slide inward.
[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0021] 1. In use, this utility model, through the design of the connecting pipe and sleeve structure, not only ensures a more reliable and airtight connection between the gas meter pipe and the sampling pipe, but also effectively prevents gas leakage, reduces leakage problems, and improves the accuracy of sampling data.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example 1, please refer to Figures 1 to 4 This utility model provides a technical solution: a gas meter sampling plate, including a sampling plate body 1, a sampling pipe 101 fixedly embedded at the top center of the sampling plate body 1, a connecting pipe 102 fixedly embedded inside the sampling pipe 101, a threaded groove 103 provided on the outer surface of the connecting pipe 102, a first sealing gasket 104 fixedly installed on the top of the sampling pipe 101, the first sealing gasket 104 fixedly sleeved on the outer surface of the connecting pipe 102, and a first sliding groove 105 provided on both sides of the outer surface of the sampling pipe 101. The inner surfaces of the two first sliding grooves 105 are slidably connected to sliders 106. Sleeves 107 are fixedly installed on the outer sides of the two sliders 106. Sleeves 107 are slidably connected to the outer surface of the sampling pipe 101. A support frame 2 is fixedly installed on the top of the sampling disc body 1. A second sealing gasket 108 is fixedly installed on the inner surface of the sleeve 107. The second sealing gasket 108 is movably sleeved on the outer surface of the sampling pipe 101. Bolts 109 are threadedly connected to both sides of the inside of the sleeve 107. A positioning groove 201 is opened at the center of the inside of the support frame 2.
[0031] In this embodiment, the operator first places the gas meter pipe onto the outer surface of the connecting pipe 102 and rotates the gas meter pipe, causing it to slide downwards on the outer surface of the connecting pipe 102 through the threaded groove 103. After sliding to a certain extent, the bottom of the gas meter pipe will adhere to the top of the first sealing gasket 104 of the sampling pipe 101. Then, the sleeve 107 is slid upwards, causing the slider 106 to slide upwards on the inner surface of the first sliding groove 105, and simultaneously causing the second sealing gasket 108 inside the sleeve 107 to slide. This allows the second sealing gasket 108 to adhere to the outer surface of the gas meter pipe and cover the connection of the gas meter pipe. After that, the operator can rotate the threaded groove 103. The bolt 109 is used to fix one end of the gas meter pipe to the outer surface of the sleeve 107, allowing gas to enter the sampling disc body 1 through the sampling pipe 101 for sampling and testing. The connection between the pipe 102 and the sleeve 107 structure not only ensures a more reliable and airtight connection between the gas meter pipe and the sampling pipe 101, but also effectively prevents gas leakage, reduces leakage problems, and improves the accuracy of sampling data. At the same time, the combination of the threaded groove 103 and the sliding sleeve 107 makes the installation process simpler. This design eliminates the need for complicated tools or extra force during installation and also reduces the error rate during installation.
[0032] Example 2, as Figures 1 to 4 As shown, the support frame 2 has a second sliding groove 202 on both sides of its top. The inner surfaces of the two second sliding grooves 202 are slidably connected to clamps 203. The outer sides of the two clamps 203 are fixedly installed with telescopic rods 205. The other ends of the two telescopic rods 205 are fixedly installed with support plates 207. The bottoms of the two support plates 207 are fixedly installed on the top of the support frame 2. The opposite sides of the two clamps 203 are fixedly installed with rubber pads 204. The outer sides of the two clamps 203 are fixedly installed with return springs 206. The inner surfaces of the two return springs 206 are movably sleeved on the outer surfaces of the telescopic rods 205. The other ends of the two return springs 206 are fixedly installed on the inner side of the support plates 207.
[0033] In this embodiment, the operator can first pull the clamp 203 outward, allowing it to slide outward through the second slide groove 202, while simultaneously squeezing the telescopic rod 205 and the return spring 206 on the support plate 207 to retract them. Then, the gas meter pipe is passed through the positioning groove 201 on the support frame 2 and fitted onto the outer surface of the connecting pipe 102. Afterward, the clamp 203 is released, causing the return spring 206 and the telescopic rod 205 to return to their original positions. As they return to their original positions, the clamp 203 is pushed inward, and the clamp 203 drives the rubber pad 204 to move synchronously, allowing the rubber pad 204 to fit against the outer surface of the gas meter pipe for positioning. The structure of the clamp 203 and the telescopic rod 205 ensures that the gas meter pipe will not shift or loosen during the connection process. This tight positioning function helps to ensure the stability of the entire pipe connection and prevents loosening or misalignment due to vibration or external interference.
[0034] Working principle: In use, the operator first places the gas meter pipe onto the outer surface of the connecting pipe 102 and rotates the gas meter pipe, causing it to slide downwards along the threaded groove 103 on the outer surface of the connecting pipe 102. After sliding to a certain extent, the bottom of the gas meter pipe will adhere to the top of the first sealing gasket 104 of the sampling pipe 101. Then, the sleeve 107 is slid upwards, causing the slider 106 to slide upwards on the inner surface of the first sliding groove 105, and simultaneously causing the second sealing gasket 108 inside the sleeve 107 to slide. This allows the second sealing gasket 108 to adhere to the outer surface of the gas meter pipe and cover the connection point of the gas meter pipe. After that, the operator can rotate the gas meter pipe. The bolt 109 is moved so that one end fits against the outer surface of the gas meter pipe to fix the sleeve 107. Then, the gas can enter the sampling disc body 1 through the sampling pipe 101 for sampling and detection. The connection between the pipe 102 and the sleeve 107 structure not only ensures a more reliable and airtight connection between the gas meter pipe and the sampling pipe 101, but also effectively prevents gas leakage, reduces leakage problems, and improves the accuracy of sampling data. At the same time, the combination of the threaded groove 103 and the sliding sleeve 107 makes the installation process simpler. This design eliminates the need for complicated tools or extra force during installation and also reduces the error rate during installation. In use, the operator can first pull the clamp 203 outward, allowing it to slide outward through the second slide groove 202, while simultaneously squeezing the telescopic rod 205 and the return spring 206 on the support plate 207 to retract them. Then, the gas meter pipe is passed through the positioning groove 201 on the support frame 2 and fitted onto the outer surface of the connecting pipe 102. Afterward, the clamp 203 is released, causing the return spring 206 and the telescopic rod 205 to return to their original positions. As they return to their original positions, the clamp 203 is pushed inward, and the clamp 203 drives the rubber pad 204 to move synchronously, allowing the rubber pad 204 to fit against the outer surface of the gas meter pipe for positioning. The structure of the clamp 203 and the telescopic rod 205 ensures that the gas meter pipe will not shift or loosen during the connection process. This tight positioning function helps to ensure the stability of the entire pipe connection and prevents loosening or misalignment due to vibration or external interference.
