Description

Technical Field

[0001] This utility model relates to the field of gas meter connector technology, and in particular to a protective structure for a gas meter connector. Background Technology

[0002] As a key device for measuring gas usage, gas meters have connectors installed on their tops to meet the connection requirements with gas pipelines. The gas meter connectors, which connect the gas meter to the gas pipeline, directly affect the safety of gas transmission due to their sealing performance and structural stability.

[0003] Currently, gas meter connectors are connected to pipes via threaded connections. During peak gas usage periods for cooking, gas pressure fluctuates significantly. When gas pressure suddenly increases, it exerts an outward pushing force on the threaded connection between the gas meter connector and the pipe. Conversely, when the pressure decreases, it generates a certain pulling force. Over time, these frequent pressure changes cause the threaded connection to be subjected to alternating stress, leading to loosening and a decrease in the sealing performance of the connector. To address these issues, we propose a protective structure for gas meter connectors. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a protective structure for gas meter connectors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective structure for a gas meter connector is installed on the gas meter body. The top of the gas meter body is symmetrically connected with threaded connectors, and the sides of the threaded connectors are connected to the pipe end via threads. The top of the gas meter body is covered with a connecting plate, and the inner side of the connecting plate has a U-shaped plate. The U-shaped plate has symmetrically provided grooves inside. A slider is fixedly connected to the side of the U-shaped plate. The inner wall of the connecting plate has a moving groove adapted to the slider, and a first spring is horizontally connected to the inner wall of the moving groove. The other end of the first spring is fixedly connected to the slider.

[0007] Preferably, the upper side of the U-shaped plate has symmetrically distributed movable plates, and the front and rear sides of the movable plates are symmetrically connected with baffles. The back of the U-shaped plate is fixedly connected with a limiting strip, and the inside of the baffle is provided with an insertion groove that matches the limiting strip.

[0008] Preferably, a pull block is provided above the movable plate, and a positioning rod is fixedly connected to the bottom end of the pull block. The positioning rod extends through the inner wall of the movable plate into the U-shaped plate, and a positioning groove adapted to the positioning rod is provided inside the U-shaped plate.

[0009] Preferably, a slot is provided at the center of the movable plate, and a second spring is fixedly connected inside the slot, with the other end of the second spring fixedly connected to the bottom end of the pull block.

[0010] Preferably, the connecting plate has holes inside that are compatible with the threaded joint, and the interior of the connecting plate is connected to the gas meter body by bolts.

[0011] Preferably, the lower side of the pull block is connected to two sets of positioning rods, and the two sets of positioning rods are symmetrically distributed about the central axis of the moving plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A protective structure for a gas meter connector is installed on the gas meter body 1. Threaded connectors 2 are symmetrically connected to the top of the gas meter body 1, and the sides of the threaded connectors 2 are connected to a pipe end 3 via threads. A threaded sleeve is connected to the bottom of the pipe end 3. The internal thread on the inner wall of the threaded sleeve can engage with the external thread on the outer wall of the threaded connector 2, thus satisfying the threaded connection requirements of the threaded connector 2 and the pipe end 3. The top of the gas meter body 1 is covered with a connecting plate 4, and a U-shaped plate 5 is provided on the inner side of the connecting plate 4. The U-shaped plate 5 has symmetrically provided reserved slots 6 inside. A slider 7 is fixedly connected to the side of the U-shaped plate 5. The inner wall of the connecting plate 4 has a moving slot adapted to the slider 7. The inner wall of the moving slot is horizontally connected to a first spring 8. The other end of the first spring 8 is fixedly connected to the slider 7. By providing reserved slots 6, the horizontal movement requirement of the U-shaped plate 5 can be met. The reserved slots 6 are located on the upper side of the threaded joint 2 and the threaded sleeve of the pipe end 3. Therefore, by moving the U-shaped plate 5 directly above the threaded joint 2, the vertical limit of the bottom threaded sleeve of the pipe end 3 can be achieved.

[0022] Furthermore, refer to Figure 2 , Figure 3 and Figure 4 It can be seen that movable plates 9 are symmetrically distributed on the upper side of the U-shaped plate 5, and baffles 10 are symmetrically connected on the front and rear sides of the movable plates 9. A limiting strip 14 is fixedly connected to the back of the U-shaped plate 5. The baffle 10 has an insertion groove that matches the limiting strip 14. The mutual cooperation between the limiting strip 14 and the insertion groove can achieve lateral guidance of the movable plates 9 and the baffles 10. Through the mutual cooperation between the movable plates 9 and the baffles 10, the threaded sleeves at the bottom of the two sets of pipe ends 3 can be laterally limited to effectively prevent the pipe ends 3 from rotating under force.

[0023] Furthermore, refer to Figure 2 and Figure 4 It can be seen that a pull block 11 is provided above the movable plate 9, and a positioning rod 12 is fixedly connected to the bottom end of the pull block 11. The positioning rod 12 extends through the inner wall of the movable plate 9 into the U-shaped plate 5, and a positioning groove adapted to the positioning rod 12 is opened inside the U-shaped plate 5. Through the cooperation of the pull block 11 and the positioning rod 12, the movable plate 9 and the baffle 10 can be limited and fixed, so as to effectively ensure the limiting effect of the baffle 10 on the pipe end 3.

[0024] Furthermore, refer to Figure 3 and Figure 4It can be seen that a slot is provided at the center of the movable plate 9, and a second spring 13 is fixedly connected inside the slot. The other end of the second spring 13 is fixedly connected to the bottom end of the pull block 11. Through the connection of the second spring 13, the tightness of the positioning rod 12 when it is inserted into the positioning slot inside the U-shaped plate 5 can be guaranteed.

[0025] Furthermore, refer to Figure 3 It can be seen that the connecting plate 4 has holes inside that are compatible with the threaded connector 2. The connecting plate 4 is connected to the gas meter body 1 by bolts. The holes can meet the requirement of covering the top of the gas meter body 1. The bolts make it easy for workers to disassemble and assemble the connecting plate 4.

[0026] Furthermore, refer to Figure 4 It can be seen that the lower side of the pull block 11 is connected to two sets of positioning rods 12, and the two sets of positioning rods 12 are symmetrically distributed about the central axis of the moving plate 9. Through the cooperation of the two sets of pull blocks 11 and positioning rods 12, the positioning effect of the moving plate 9 can be further guaranteed.

[0027] Working Principle: In use, the operator first installs the gas meter body 1 in a suitable position. Then, the operator pulls the U-shaped plate 5 horizontally, causing the slider 7 connected to its side to slide against the inner wall of the moving groove. This pushes the U-shaped plate 5 away from the threaded connector 2. The operator then rotates the pipe end 3, and through the threaded sleeve at its bottom, it can be threadedly connected to the corresponding threaded connector 2. After installing the pipe end 3, the operator stops pulling the U-shaped plate 5. The pre-drilled groove 6 inside the U-shaped plate 5 moves to the center of the connecting plate 4. The top of the U-shaped plate 5 is positioned above the threaded sleeve at the bottom of the pipe end 3 to achieve vertical positioning of the pipe end 3. Then, the operator can pull up the pull block 11 in sequence to drive the positioning rod 12 to receive an upward force, thereby pushing the moving plate 9 and causing the baffle 10 connected to its bottom to be stressed. When the baffle 10 is moved to the front of the reserved groove 6, the positioning rod 12 corresponds to the position of another set of positioning grooves opened inside the U-shaped plate 5, thereby achieving lateral positioning of the threaded sleeve at the bottom of the pipe end 3, which further ensures the reliability and safety of the pipe end 3 during operation. The above is the complete working principle of this utility model.
