Detailed Implementation

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 As shown, this utility model is a low-leakage hydraulic valve group sealing assembly, including a hydraulic valve group 1, on which a connecting mechanism 2 and several configuration mechanisms 3 are provided:

[0028] The connecting mechanism 2 includes a connector 21 fixedly connected to the right side of the hydraulic valve assembly 1. A sealing groove 22 is provided on the right side of the connector 21. A sealing ring 23 is provided on the inner wall of the sealing groove 22. A connecting pipe 24 is slidably fitted onto the inner wall of the sealing groove 22, and the connecting pipe 24 is adapted to the sealing ring 23. Several sliding rods 25 are fixedly connected to the right side of the hydraulic valve assembly 1. Two T-blocks 26 are slidably fitted onto the outer wall of each sliding rod 25. Rotary blocks 27 are rotatably connected to the right side of each T-block 26. Limit rods 28 are fixedly connected to the side of each rotating block 27 closest to the hydraulic valve assembly 1. The left ends of rods 28 extend into connecting pipes 24 and joints 21 and are slidably connected to them. The outer walls of several sliding rods 25 are wrapped with springs 29. One end of each spring 29 is fixedly connected to two T-blocks 26, and the other end of each spring 29 is fixedly connected to the hydraulic valve assembly 1. Two screws 291 are fixedly connected to the right side of the hydraulic valve assembly 1. Both screws 291 pass through the two T-blocks 26 and are slidably connected to them. The outer walls of both screws 291 are threaded with manual turntables 292.

[0029] By setting up a connecting mechanism, if the sealing ring 23 needs to be replaced, the manual turntable 292 on the outer wall of the screw 291 can be rotated outward to move the manual turntable 292 outward, thereby releasing the limit on the T-block 26 on the screw 291. At this time, the T-block 26 will drive the rotating block 27 and the limiting rod 28 on the rotating block 27 to move outward under the push of the spring 29 on the outer wall of the slide rod 25. When it moves to the appropriate position, the rotating block 27 can be rotated to both sides, so that the limiting rod 28 on it can release the limit on the connecting pipe 24 and the connector 21, thereby separating the connecting pipe 24 from the connector 21, thus facilitating the replacement of the sealing ring 23. This design simplifies the cumbersome steps in the traditional installation and disassembly process and effectively improves the installation efficiency.

[0030] The configuration mechanism 3 includes a U-shaped block 31 fixedly connected to the back of the hydraulic valve group 1. A screw 32 is slidably sleeved on the U-shaped block 31. A manual turntable 33 is threaded on the outer wall of the screw 32. A folding groove 34 is opened on the outer wall of the screw 32. Two folding rods 35 are hinged to the inner wall of the folding groove 34. Both folding rods 35 are adapted to the folding groove 34. A spring 36 is fixedly connected to the side of the two folding rods 35 that are close to each other.

[0031] By setting up a configuration mechanism, if a quick installation of the entire device is required, screw 2 32 can be inserted into the corresponding fixing slot. At the moment of insertion, the two folding rods 35 on screw 2 32 will contact the inner wall of the fixing slot. Due to the limited space in the fixing slot, the folding rods 35 will be squeezed, thereby compressing the spring 2 36 inside. At this time, the folding rods 35 will retract into the folding slot 34, avoiding obstruction of the screw 2 32's penetration action. After screw 2 32 successfully penetrates the fixing slot, the spring 2 36, which was previously in a compressed state, will release its elasticity, pushing the folding rods 35 to quickly return to their original position. Next, the operator rotates the manual turntable 2 33 on the outer wall of screw 2 32. Through the rotation of the manual turntable 2 33, screw 2 32 will retract under the action of the thread, cooperating with the two folding rods 35 that have already returned to their original position, tightly pressing against the bottom wall of the fixing slot, thereby ensuring that the hydraulic valve assembly 1 is firmly fixed in the corresponding position.

[0032] A specific application of this embodiment is as follows: If the sealing ring 23 needs to be replaced, the manual turntable 292 on the outer wall of the screw 291 can be rotated outward to move the manual turntable 292 outward, thereby releasing the restriction on the T-block 26 on the screw 291. At this time, the T-block 26 will drive the rotating block 27 and the limiting rod 28 on the rotating block 27 to move outward under the push of the spring 29 on the outer wall of the slide rod 25. When it moves to the appropriate position, the rotating block 27 can be rotated to both sides, so that the limiting rod 28 on it can release the restriction on the connecting pipe 24 and the connector 21, thereby separating the connecting pipe 24 from the connector 21, thus facilitating the replacement of the sealing ring 23. Through this design, the cumbersome steps in the traditional installation and disassembly process can be simplified, effectively improving the installation efficiency; and when the entire device needs to be quickly installed, it can be... Screw 2 32 is inserted into the corresponding fixing groove. At the moment of insertion, the two folding rods 35 on screw 2 32 will contact the inner wall of the fixing groove. Due to the limited space in the fixing groove, the folding rods 35 will be squeezed, which will compress the spring 2 36 inside. At this time, the folding rods 35 will retract into the folding groove 34, avoiding obstruction of the screw 2 32's penetration action. After screw 2 32 successfully penetrates the fixing groove, the spring 2 36, which was previously in a compressed state, will release its elasticity and push the folding rods 35 to quickly return to their original position. Next, the operator rotates the manual turntable 2 33 on the outer wall of screw 2 32. Through the rotation of the manual turntable 2 33, screw 2 32 will retract under the action of the thread, cooperating with the two folding rods 35 that have been reset, and tightly abutting against the bottom wall of the fixing groove, thereby ensuring that the hydraulic valve assembly 1 is firmly fixed in the corresponding position.
