[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-5An embodiment of this utility model provides a quick-sealing connector for a gas valve, including a valve pipe 1 and a gas pipe 2. One end of the valve pipe 1 is provided with a gas pipe 2, and a connecting pipe 13 is provided inside the end of the valve pipe 1 near the gas pipe 2. L-shaped inserts 12 are provided on the outer edges of the connecting pipe 13 away from the valve pipe 1. An annular groove 11 is provided on the inner wall of the gas pipe 2 corresponding to the L-shaped inserts 12. L-shaped slots 19 are provided on the inner wall of the gas pipe 2 in the clockwise direction of the L-shaped inserts 12, and the L-shaped inserts 12 are engaged with the corresponding L-shaped slots 19.

[0024] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, insert the connecting pipe 13 at one end of the valve pipe 1 into the gas pipe 2, and insert the L-shaped plug 12 on the outside of the connecting pipe 13 into the annular groove 11. Then, the valve pipe 1 can be rotated to make the connecting pipe 13 rotate, and the connecting pipe 13 will make the L-shaped plug 12 rotate clockwise and be inserted into the L-shaped slot 19 to make it quickly connected.

[0025] On the outer side of the end where valve pipe 1 and gas pipe 2 are in contact, there are respectively annular plate 14 and annular plate 25. On the side of annular plate 25 near annular plate 14, there are locking blocks 10 in the middle of each side. The locking blocks 10 are respectively provided with arc grooves 20 on annular plate 14, and the arc grooves 20 are engaged with the locking blocks 10. On the outer side of annular plate 14, there are grooves 8 in the middle of the locking blocks 10, and there are screws 21 in the middle of the grooves 8. The locking blocks 10 and annular plate 14 corresponding to the screws 21 are respectively provided with threaded holes, and the screws 21 are threadedly connected to the locking blocks 10 and annular plate 14 through the threaded holes.

[0026] Specifically, such as Figure 2 and Figure 5 As shown, when the valve pipe 1 is connected and rotated, the outer annular plate 14 can rotate synchronously, which can cause the outer annular plate 15 of the gas pipe 2 to drive the locking block 10 into the arc groove 20. Then, the screw 21 can be rotated in the groove 8, so that the screw 21 is screwed into the threaded hole of the locking block 10 and the annular plate 14, which can fix the locking block 10, prevent the locking block 10 from falling out of the arc groove 20, and improve the stability of the connection.

[0027] Furthermore, an annular cover 3 is provided on the outer side of the second annular plate 15 and the first annular plate 14. Springs 7 are evenly provided at the top and bottom of the inner side of the annular cover 3. The other end of the springs 7 is provided with an elastic annular cover 9. The inner side of the annular cover 9 is in contact with the outer side of the first annular plate 14 and the second annular plate 15. An annular connecting block 4 is provided on the outer side of the gas pipe 2 away from the valve pipe 1. Spring strips 5 are provided around the annular connecting block 4 near the edge of the annular cover 3. The other end of the spring strips 5 is connected to the annular cover 3. The middle sections on both sides of the annular cover 3 are provided with telescopic sections 6.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, after the valve pipe 1 and the gas pipe 2 are connected, the annular cover 3 can be pulled by the spring strip 5, so that the annular cover 3 is opened by the telescopic section 6 and covers the outside of the annular plate 14 and the annular plate 2 15. At the same time, the elastic annular cover 9 covers the outside of the annular plate 14 and the annular plate 2 15. Then, the spring 7 inside the annular cover 3 is compressed, so that the annular cover 9 fits tightly against the outside of the annular plate 14 and the annular plate 2 15. This can protect the annular plate 14 and the annular plate 2 15 and prevent them from being damaged during use, thus affecting their connection and sealing effect.

[0029] A sealing ring 18 is provided in the annular groove 11 near the valve pipe 1, and an annular air pad 16 is provided on the inner wall of the annular groove 11 between the sealing ring 18 and the L-shaped insert 12. An air inlet pipe 17 is evenly provided in the side wall of the gas pipe 2 outside the sealing ring 18, and one end of the air inlet pipe 17 extends into the annular air pad 16, and the other end of the air inlet pipe 17 is flush with the edge of the gas pipe 2.

[0030] Specifically, such as Figure 2 and Figure 3 As shown, a sealing ring 18 is provided in the annular groove 11 that connects valve pipe 1 and gas pipe 2 for sealing. When a gap is formed between valve pipe 1 and gas pipe 2, gas can enter the annular inflation pad 16 through the air inlet pipe 17. The annular inflation pad 16 expands after being squeezed by the gas, which seals the annular groove 11 and squeezes the sealing ring 18 to prevent gas leakage.

[0031] Working principle: In use, insert the connecting pipe 13 at one end of the valve pipe 1 into the gas pipe 2, and insert the L-shaped insert 12 on the outside of the connecting pipe 13 into the annular groove 11. Then, rotate the valve pipe 1, causing the connecting pipe 13 to rotate, which in turn causes the L-shaped insert 12 to rotate clockwise and engage in the L-shaped slot 19, allowing for quick connection. Simultaneously, the annular plate 14 on the outside of the valve pipe 1 can rotate synchronously, causing the annular plate 15 on the outside of the gas pipe 2 to engage the locking block 10 into the arc-shaped groove 20. Then, rotate the screw 21 in the groove 8, causing the screw 21 to screw into the threaded hole of the locking block 10 and the annular plate 14, which can fix the locking block 10 and prevent it from dislodging from the arc-shaped groove 20, thus improving the stability of the connection. After the connection is complete, it can be pulled by the spring strip 5. The annular cover 3 is pulled open by the telescopic section 6 to cover the outside of the annular plate 14 and the annular plate 2 15, and the elastic annular cover 9 is simultaneously covered on the outside of the annular plate 14 and the annular plate 2 15. Then, the spring 7 inside the annular cover 3 is compressed, so that the annular cover 9 fits tightly against the outside of the annular plate 14 and the annular plate 2 15, which can protect the annular plate 14 and the annular plate 2 15 and prevent them from being damaged during use, thus affecting their connection and sealing effect. When a gap is formed between the valve pipe 1 and the gas pipe 2, gas can enter the annular air pad 16 through the air inlet pipe 17. The annular air pad 16 expands after being squeezed by the gas, which seals the annular groove 11 and squeezes the sealing ring 18 to prevent gas leakage.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
