[0029] As described in the background art, the safety valve is generally installed near the natural gas meter or close to the gas stove. Therefore, the installation position of the safety valve is relatively low, and it is easy to be accidentally touched by the safety switch by playful children during use, resulting in the abnormal use of natural gas and causing unnecessary trouble.

[0030] To solve this technical problem, the present utility model provides a gas blocking valve that is easy to install, which is applied to a gas system.

The inner wall of the support base 3 is rotatably connected to a rotating shaft 7, and the outer wall of the rotating shaft 7 is fixedly connected to a protective cover 6.

[0034] For the gas blocking valve that is convenient for installation provided by the present utility model, by pulling the pull rod 14, the connecting plate 15 can drive the insertion block 16 to move accordingly. Press down the pressing rod 9 and rotate the rotating hook 19 therewith, and the rotating hook 19 can be hooked in the reinforcing frame 22. Then, release the pressing rod 9, and it can move upward under the elastic force of the first spring 11. And under the restriction of the rotating hook 19 and the reinforcing frame 22, the rotating hook 19 rises until the insertion hole 13 is aligned with the insertion block 16. Then, release the pull rod 14 to make the insertion block 16 insert into the insertion hole 13, further restricting the position of the pressing rod 9. By inserting the insertion block 16 into the insertion hole 13, the connection between the pressing rod 9 and the support shell 12 can be enhanced, thereby enhancing the connection between the protective cover 6 and the support base 3, and further increasing the stability of the protective cover 6 covering on the support base 3. At the same time, the rotating hook 19 is hooked on the reinforcing frame 22, increasing the connection between the protective cover 6 and the support base 3 and the safety valve body 1, improving the overall stability of the device.

[0035] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings.

[0036] Embodiment 1:

[0037] Please refer to Figures 2-6 , a gas blocking valve that is convenient for installation, which includes:

[0038] The pressing component includes a fixed sleeve 8. The outer wall of the protective cover 6 is fixedly connected to a fixed sleeve 8. The inner wall of the fixed sleeve 8 is slidably connected to a pressing rod 9. The outer wall of the pressing rod 9 is fixedly connected to a sliding block 10. The sliding block 10 is slidably connected to the inner wall of the fixed sleeve 8. A first spring 11 is sleeved outside the pressing rod 9. The upper and lower ends of the first spring 11 are respectively fixedly connected to the bottom of the sliding block 10 and the lower surface of the inner wall of the fixed sleeve 8. The sliding block 10 prevents the pressing rod 9 from sliding upward excessively when the protective cover 6 is in the open state.

[0039] The limiting component includes a support shell 12. The outer wall of the support base 3 is fixedly connected to the support shell 12. The pressing rod 9 is slidably connected to the inner wall of the support shell 12. A plurality of jacks 13 are formed in the outer part of the pressing rod 9. A pull rod 14 is slidably connected to the inner wall of the support shell 12. One end of the pull rod 14 located inside the support shell 12 is fixedly connected to a connecting plate 15. A plurality of insertion blocks 16 are fixedly connected to the outer wall of the connecting plate 15. The insertion blocks 16 are inserted into the jacks 13. The width of the jacks 13 is the same as the width of the insertion blocks 16, but the height of the jacks 13 is slightly greater than the height of the insertion blocks 16. A second spring 17 is sleeved on the outer part of the pull rod 14. The two ends of the second spring 17 are respectively fixedly connected to the outer wall of the connecting plate 15 and the inner wall of the support shell 12. Two limiting rods 18 are fixedly connected to the outer wall of the connecting plate 15. Both of the two limiting rods 18 are slidably connected to the inner wall of the support shell 12.

[0040] The connecting component includes a bottom half-ring 20. The outer wall of the safety valve body 1 is closely attached to the bottom half-ring 20. A rotating block 21 is rotatably connected to the outer wall of the bottom half-ring 20. The bottom half-ring 20 and the rotating block 21 are detachably connected by bolts. A reinforcing frame 22 is fixedly connected to the top of the rotating block 21. A rotating hook 19 adapted to the reinforcing frame 22 is rotatably connected to the inner wall of the pressing rod 9. After the insertion block 16 is inserted into the jack 13, the pressing rod 9 can move upward by a certain distance under the action of the elastic force of the first spring 11, so that the rotating hook 19 stably hooks the reinforcing frame 22. And a groove adapted to the reinforcing frame 22 is formed at the position where the rotating hook 19 contacts the reinforcing frame 22, so that the reinforcing frame 22 is stably clamped in the groove of the rotating hook 19 under the action of the elastic force of the first spring 11, improving the connection between the protective cover 6, the support base 3 and the safety valve body 1, and improving the overall stability of the device.

[0041] Through the above structural design, pulling the pull rod 14 causes the pull rod 14 to slide inside the support shell 12. At the same time, the second spring 17 deforms accordingly, and the limiting rod 18 slides inside the support shell 12 accordingly. The connecting plate 15 drives the insertion block 16 to move accordingly. Pressing down the pressing rod 9 causes the pressing rod 9 and the sliding block 10 to slide inside the fixed sleeve 8. At the same time, the first spring 11 deforms accordingly. Subsequently, rotating the rotating hook 19 can hook the rotating hook 19 inside the reinforcing frame 22. Then, releasing the pressing rod 9 allows it to move upward under the elastic force of the first spring 11. And under the restriction of the rotating hook 19 and the reinforcing frame 22, the rotating hook 19 rises until the insertion hole 13 is aligned with the insertion block 16 and then stops rising. Subsequently, releasing the pull rod 14 allows the insertion block 16 to be inserted into the insertion hole 13 under the elastic force of the second spring 17. When it is necessary to open the protective cover 6, pull the pull rod 14 to make the insertion block 16 leave the insertion hole 13. Then, pull down the pressing rod 9 to make the rotating hook 19 leave the reinforcing frame 22. Subsequently, rotate the rotating hook 19 to stagger the rotating hook 19 from the reinforcing frame 22. Then, release the pressing rod 9 to make the pressing rod 9 rise under the elastic force of the first spring 11 until the pressing rod 9 leaves the support shell 12. Then, release the pull rod 14, and pulling the protective cover 6 can open the protective cover 6.

[0042] Embodiment 2:

[0043] Further optimize the gas blocking valve provided in Embodiment 1. Specifically, as Figure 3 shown, the limiting mechanism 4 includes a threaded rod 23. The inner wall of the protective cover 6 is threadedly connected with the threaded rod 23. The threaded rod 23 is inserted into the support seat 3. The threaded rod 23 further restricts the protective cover 6 from covering on the support seat 3. Cooperating with the reinforcing mechanism 5 to double-restrict the protective cover 6, it improves the situation that the protective cover 6 is accidentally touched and opened, and then the safety valve body 1 is wrongly operated.

[0044] The limiting mechanism 4 further includes a fixing ring 24. A fixing ring 24 is fixedly connected to the outer wall of the rotating shaft 7 and located in the middle. On the outer part of the rotating shaft 7 and on the upper and lower sides of the fixing ring 24, torsion springs 25 are respectively sleeved. The two ends of the two torsion springs 25 are respectively fixedly connected to the outer wall of the fixing ring 24 and the inner wall of the support seat 3. The torsion spring 25 makes the protective cover 6 always have a tendency to open. Therefore, after the protective cover 6 is opened, it will not automatically close without external force.

[0045] Through the above structural design, when it is necessary to open the protective cover 6, rotate the threaded rod 23 to make the threaded rod 23 leave the support seat 3. Then, under the elastic force of the torsion spring 25, the protective cover 6 is opened accordingly. When it is necessary to close the protective cover 6, push the protective cover 6 to make the protective cover 6 drive the rotating shaft 7 to rotate relative to the support seat 3. Then, the torsion spring 25 will further deform. After the protective cover 6 is closed, reverse the threaded rod 23 to make the threaded rod 23 inserted into the support seat 3.
