[0004] However, due to the complex structure of the housing and valve core of the ball valve, the ball valve usually needs to be packaged before being carried and transported, which is inconvenient. Utility Model Content

[0005] In order to improve the convenience of carrying and transporting the ball valve, the present application provides a convenient anti-leakage ball valve.

[0006] The present application provides a convenient anti-leakage ball valve, which adopts the following technical solution:

[0007] A convenient anti-leakage ball valve comprises a connecting pipe and a valve body arranged on the connecting pipe, wherein a valve cover is rotatably arranged on the connecting pipe and covers the valve body, a limiting mechanism is arranged on the connecting pipe and limits the position of the valve cover when covering the valve body, and a pull ring is arranged on the valve cover.

[0008] By adopting the above technical solution, a valve cover is provided on the upper cover of the valve body, and then the valve cover is limited by a limiting component, and a pull ring is installed on the valve cover, so that the user can move and transport the overall ball valve by pulling the pull ring, which is convenient and fast. Moreover, during the movement and transportation process, the valve cover can also protect the valve body, reducing the probability of the valve body being damaged by collision with the outside during transportation. There is no need for separate outer packaging of the valve body, which is more portable. And when the valve body is used subsequently, the valve cover can still protect the valve body, reducing the probability of the valve body aging due to long-term exposure to the environment.

[0009] Optionally, the limiting mechanism includes:

[0010] A first limiting block, which is arranged on the connecting pipe. A vertical insertion slot is opened on the first limiting block. When the valve cover covers the valve body, the valve cover is in plug-in fit with the insertion slot.

A limiting slot communicating with the sliding slot is opened on the first limiting block. The second limiting block is horizontally slidably installed on the sliding slot and is in plug-in fit with the limiting slot.

[0012] A moving component, which is arranged on the first limiting block and is used to control the movement of the second limiting block in the sliding slot.

[0013] By adopting the above technical solution, rotate the valve cover of the valve body, and the valve cover is in plug-in fit with the insertion slot on the first limiting block. Then, move the second limiting block through the moving component so that part of it extends out of the sliding slot and is in plug-in fit with the limiting slot, thereby completing the fixing work of the position of the valve cover. When the valve cover needs to be opened, use the moving component to move the second limiting block to disengage from the valve cover, which is convenient and fast.

[0014] Optionally, the moving component includes:

[0015] A moving spring, which is arranged on the inner bottom wall of the sliding slot and is connected to the second limiting block. The second limiting block extends out of the sliding slot and is in plug-in fit with the limiting slot under the action of the moving spring.

[0025] A second bevel gear is disposed on the rotating shaft and meshes with the first bevel gear.

[0026] By adopting the above technical solution, when the pull ring needs to be pulled, the rotation button is rotated, and the rotation of the rotation button drives the first bevel gear to rotate, the rotation of the first bevel gear drives the second bevel gear to rotate, the rotation of the second bevel gear drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the pull ring to rotate, thereby realizing the rotation of the pull ring by controlling the rotation button.

[0027] Optionally, anti-slip grooves are provided on the outer circumferential wall of the pull ring.

[0028] By adopting the above technical solution, anti-slip grooves are provided on the outer circumferential wall of the pull ring, thereby increasing the friction when the user pulls the pull ring and reducing the probability that the pull ring slips off the hand when the user pulls the pull ring.

[0040] The following further elaborates on this application in conjunction with the attached Figure 1 - attached Figure 4 drawings for a more detailed description.

[0041] The embodiment of this application discloses a convenient anti-leakage ball valve.

[0042] Referring to Figure 1 , the convenient anti-leakage ball valve includes a connecting pipe 11 and a valve body 12 fixedly installed on the connecting pipe 11. A valve cover 13 is rotatably installed on the connecting pipe 11, and the valve cover 13 covers the valve body 12. The valve cover 13 is made of transparent acrylic material. A limiting mechanism 2 is provided on the connecting pipe 11, and the limiting mechanism 2 limits the position of the valve cover 13 when covering the valve body 12.

[0043] Referring to Figure 1 and Figure 2 , the limiting mechanism 2 includes a first limiting block 21, a second limiting block 22 and a moving component 23.

[0044] Referring to Figure 2 and Figure 3 , the first limiting block 21 is fixedly installed on the outer side wall of the connecting pipe 11. A vertical insertion slot 14 is formed on the upper surface of the first limiting block 21. When the valve cover 13 covers the valve body 12, the valve cover 13 is in plug-in fit with the insertion slot 14. A horizontal sliding slot 15 is formed on the inner side wall of the insertion slot 14 of the first limiting block 21, and a limiting slot 16 communicating with the sliding slot 15 is formed on the outer side wall of the part of the first limiting block 21 inserted into the insertion slot 14. The second limiting block 22 is horizontally slidably installed on the sliding slot 15 and is in plug-in fit with the limiting slot 16.

[0045] Referring to Figure 2 and Figure 3The moving assembly 23 is arranged on the first limit block 21 and is used to control the second limit block 22 to move in the sliding groove 15. The moving assembly 23 includes a moving spring 24 and a moving rod 25. One end of the moving spring 24 is fixedly mounted on the inner bottom wall of the sliding groove 15, and the other end of the moving spring 24 is fixedly connected to the second limit block 22. Under the action of the moving spring 24, the second limit block 22 partially passes out of the sliding groove 15 and is plugged into the limit groove 16. The moving rod 25 is horizontally slidably mounted on the first limit block 21, one end of the moving rod 25 is located outside the first limit block 21, and the other end of the moving rod 25 extends into the sliding groove 15 and is connected to the second limit block 22.

[0046] Reference Figure 2 and Figure 3 When the valve cover 13 covers the valve body 12, the valve cover 13 is plugged into the plug-in groove 14 on the first limit block 21. Under the action of the moving spring 24, the second limit block 22 partially passes through the sliding groove 15 and plugs into the limit groove 16, and the second limit block 22 limits the position of the valve cover 13. When the valve cover 13 needs to be opened, the moving rod 25 is pulled to drive the second limit block 22 to compress the moving spring 24 and move until the second limit block 22 is pulled into the sliding groove 15 as a whole, and then the second limit block 22 is separated from the valve cover 13, and the valve cover 13 can be rotated freely.

The second bevel gear 43 is fixedly mounted on the rotating shaft 31 and meshes with the first bevel gear 42.

[0050] Referring to Figure 4 , when it is necessary to pull the pull ring 32, rotate the rotating button 41. The rotation of the rotating button 41 drives the rotation of the first bevel gear 42. The rotation of the first bevel gear 42 drives the rotation of the second bevel gear 43. The rotation of the second bevel gear 43 drives the rotation of the rotating shaft 31. The rotation of the rotating shaft 31 drives the rotation of the pull ring 32, so that the rotation of the pull ring 32 is realized by controlling the rotating button 41.

[0051] The working principle of the embodiment of the present application is as follows:

[0052] A valve cover 13 is provided on the upper cover of the valve body 12, and then the valve cover 13 is limited by the second limiting block 22, and a pull ring 32 is installed on the valve cover 13, so that the user can move and transport the whole ball valve by pulling the pull ring 32, which is convenient and fast. And during the movement and transportation process, the valve cover 13 can also protect the valve body 12, reducing the probability of the valve body 12 being damaged by collision with the outside during transportation, and there is no need to carry out a separate outer package for the valve body 12, which is more portable. When the valve body 12 is used subsequently, the valve cover 13 can still protect the valve body 12, reducing the probability of the valve body 12 aging due to long-term exposure to the environment.

[0053] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
