[0021] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Example:

[0024] See attached Figure 1-Figure 3 The embodiment is a convenient quick opening and closing gate valve, comprising a valve body 1, a valve cover 2 is fixedly installed on the top of the valve body 1, a valve stem 3 is slidably connected to the valve cover 2, a gate plate 4 is fixedly installed on the bottom of the valve stem 3, and the valve stem 3 drives the gate plate 4 to move longitudinally to realize the opening and closing of the gate valve.

[0025] See attached Figure 1 and Figure 2 , brackets 5 are fixedly installed on both sides of the valve cover 2, and reinforcement frames 14 are fixedly installed between the two brackets 5 and the valve cover 2. At the same time, the brackets 5 and the reinforcement frames 14 are both broken line structures, which not only enhances the connection strength between the valve cover 2 and the brackets 5, but also improves the stability of the overall structure to prevent deformation or loosening under high pressure or vibration environment.

[0026] See attached Figure 1 and Figure 2 A mounting block 6 is fixedly installed on the top of the bracket 5. A connecting hole is opened on the mounting block 6. The connecting hole is arranged horizontally and has a rectangular structure. The mounting block 6 is slidably connected to a pull rod 7 through the connecting hole. The rectangular connecting hole is used to ensure the stability of the pull rod 7 during movement. A pull ring 8 is fixedly installed on the outer end of the pull rod 7. Anti-slip particles are arranged on the outer wall of the pull ring 8. The anti-slip particles increase the friction between the pull ring 8 and the palm of the operator, which facilitates operation and increases the holding stability.

[0027] See attached Figure 2 and Figure 4, a plurality of plug-in holes are provided on the pull rod 7 at equal intervals, and a limit piece 9 is arranged in the plug-in hole. The limit piece 9 comprises a plug-in rod 901, and a mounting hole is provided on the plug-in rod 901. A No. 2 spring 902 is fixedly installed in the mounting hole. A limit block 903 is slidably connected in the mounting hole, and the limit block 903 is fixedly connected to the No. 2 spring 902. When the pull rod 7 moves to a suitable position, the limit piece 9 is inserted into the plug-in hole to lock the position of the pull rod 7. During this process, the operator aligns the plug-in rod 901 with one of the plug-in holes on the pull rod 7, and then manually presses to push the limit block 903 into the plug-in hole. During the pushing process, the No. 2 spring 902 is compressed, and the limit block 903 gradually enters the plug-in hole. When the plug-in rod 901 is fully inserted into the plug-in hole, the limit block 903 just pops out of the mounting hole, that is, the connection between the limit piece 9 and the pull rod 7 is realized, and the locking of the pull rod 7 is realized.

[0028] Refer to the attached Figure 1 and Figure 2 An upper connecting seat 10 is fixedly installed on the pull rod 7, and a No. 1 spring 15 is arranged between the mounting block 6 and the upper connecting seat 10 on the same side. The No. 1 spring 15 plays a buffering and resetting role. A top plate 11 is fixedly installed on the top of the valve stem 3, and lower connecting seats 12 are fixedly installed on both sides of the top plate 11. A connecting rod 13 is arranged between the upper connecting seat 10 and the lower connecting seat 12 on the same side, which converts the linear motion of the pull rod 7 into the vertical motion of the valve stem 3, thereby realizing the lifting and lowering control of the gate 4.

[0029] Among them, the pull rod 7, the pull ring 8 and the connecting rod 13 are all made of aluminum alloy material, which not only ensures sufficient strength and rigidity, but also reduces the overall weight and improves the convenience and flexibility of operation.

[0030] The utility model drives the pull rod 7 to slide in the connecting hole by pulling the pull ring 8, and the pull rod 7 drives the valve stem 3 to move up and down through the connecting rod 13, thereby driving the gate plate 4 to rise and fall to control the opening and closing of the valve. The design of the limit member 9 ensures that the pull rod 7 can be firmly locked in a specific position to prevent accidental sliding.

[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
