Detailed Implementation

[0030] 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.

[0031] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a hydraulic end valve box with an interface anti-detachment structure, including an anti-detachment shell 1, a valve box frame 3 fixedly connected to the bottom of the outer wall of the anti-detachment shell 1, a hydraulic cylinder 4 fixedly connected to the middle of the inner wall of the anti-detachment shell 1, connecting pipes 5 fixedly connected to the front and rear ends of the outer wall of the valve box frame 3, a fixing frame 6 fixedly connected to the right side of the outer wall of the front connecting pipe 5, a connecting frame 7 slidably connected to the middle of the inner wall of the fixing frame 6, a fixing plate 8 rotatably connected to the front and rear sides of the outer wall of the connecting frame 7, an adjusting plate 9 rotatably connected to the adjacent side of the inner wall of the fixing plate 8, a connecting rod 10 rotatably connected to the left side of the inner wall of the adjusting plate 9, a support plate 11 fixedly connected to one end of the outer wall of the connecting rod 10, a fixing block 12 fixedly connected to the adjacent side of the outer wall of the fixing plate 8, a control mechanism 2 fixedly connected to the top of the outer wall of the anti-detachment shell 1, the control mechanism 2 being used to control the valve, a wear-resistant ring 13 fixedly connected to the bottom of the outer wall of the connecting plate 201, and a fixing pad 14 fixedly connected to the bottom of the outer wall of the wear-resistant ring 13.

[0032] Specifically, the hydraulic cylinder 4 is the core of the hydraulic valve box. The reciprocating motion of the piston inside achieves hydraulic transmission. When the piston moves outward, the negative pressure inside the hydraulic cylinder 4 draws in external liquid through the connecting pipe 5. When the piston moves inward, the liquid inside the hydraulic cylinder 4 is pressurized and discharged through the connecting pipe 5. The connecting pipe 5 connects to the external pipeline to form an interface anti-detachment structure. After connection, rotating the adjusting plate 9 can drive the connecting rod 10 and the support plate 11, causing the support plate 11 to abut against the external pipeline. Different support forces are provided by changing the angle of the adjusting plate 9 to prevent the interface from detaching due to hydraulic impact or vibration. The fixing plate 8 and the fixing block 12 enhance structural stability and ensure that the anti-detachment structure can withstand external forces. The top fixed control mechanism 2 is fixedly connected to the outer wall of the anti-detachment shell 1. The main function and purpose of the control mechanism 2 is to precisely control the opening and closing of the valve and ensure the smooth operation of the entire system. A wear-resistant ring 13 is connected to the bottom of the outer wall of the connecting plate 201. The function of the wear-resistant ring 13 is to protect the bottom of the outer wall of the connecting plate 201 so that it is not easily worn during long-term use. A fixing pad 14 is also fixedly connected to the bottom of the outer wall of the wear-resistant ring 13. The presence of the fixing pad 14 is to further enhance the stability and durability of the wear-resistant ring 13 and ensure that it can maintain its best performance in various working environments.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The control mechanism 2 includes a connecting plate 201, which is fixedly connected to the top of the outer wall of the anti-detachment shell 1. A rotating shaft 202 passes through the middle of the inner wall of the connecting plate 201. A fixing plate 203 is fixedly connected to the top of the outer wall of the rotating shaft 202. A handle 204 is fixedly connected to the top of the outer wall of the fixing plate 203. Adjusting rods 205 are slidably connected to the left and right sides of the outer wall of the handle 204. Adjusting rods 205 are fixedly connected to the top left and right sides of the connecting plate 201. A sealing plug 206 is fixedly connected to the bottom of the outer wall of the rotating shaft 202. Bolts 207 are threaded around the outer wall of the connecting plate 201. A cover plate 15 is rotatably connected to the top of the outer wall of the valve box frame 3. An exhaust hole 16 is opened on the front side of the top of the valve box frame 3. Sealing gaskets 17 are fixedly connected to the front and rear sides of the outer wall of the liquid cylinder 4. Multiple fixing rods 18 are threaded around the outer wall of the sealing gasket 17.

[0034] Specifically, the rotating shaft 202 passes through the connecting plate 201, and its bottom sealing plug 206 is used to control the opening and closing of the hydraulic valve box. Rotating the rotating shaft 202 causes the sealing plug 206 to rotate and engage with the opening to achieve a seal, preventing liquid leakage. The fixing plate 203 is fixed to the top of the rotating shaft 202, and its handle 204 is slidably connected to the adjusting rod 205. Rotating the rotating shaft 202 causes the fixing plate 203 to rotate, and due to the restriction of the adjusting rod 205, the handle 204 moves horizontally, driving the fixing plate 203 and its connected components to adjust their positions, thus achieving the adjustment function. The connecting plate 201 is fixed to the anti-detachment shell 1 by bolts 207 to ensure the stability of the control mechanism 2 and guarantee normal operation. The top of the valve box frame 3 rotates... The cover plate 15 is connected to the valve box frame 3, allowing it to open and close flexibly. An exhaust port 16 is provided on the front top of the valve box frame 3, which can effectively release excess gas and pressure accumulated in the system, ensuring the safe operation of the entire system. Sealing gaskets 17 are fixed on both the front and rear sides of the outer wall of the hydraulic cylinder 4. These sealing gaskets 17 can not only prevent liquid leakage, but also absorb vibration and reduce noise to a certain extent. Multiple fixing rods 18 are connected to the outer wall of the sealing gasket 17 by threads. The function of these fixing rods 18 is to further strengthen the connection stability between the sealing gasket 17 and the hydraulic cylinder 4, ensuring that the sealing gasket 17 can maintain a good sealing effect in various working environments.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A flange 19 is fixedly connected to the outer wall of the left connecting pipe 5. Bolts 20 are threaded around the outer wall of the flange 19. Support rods 21 are rotatably connected to the middle of the outer wall of the two adjusting plates 9. Pulleys 22 are rotatably connected to the adjacent sides of the inner wall of the two support rods 21. Gaskets 23 are threaded to the top right of the two fixed plates 8. Limit rods 24 pass through the middle of the outer wall of the gaskets 23.

[0036] Specifically, in this hydraulic valve box structure, the left connecting pipe 5 is connected to external equipment through the flange 19 on the left side of the outer wall and is fastened by bolts 20 with threads on all four sides to ensure the connection is sealed and stable. The adjusting plate 9 can rotate around the connection with the fixed plate 8. The support rod 21 rotatably connected in the middle of its outer wall can adjust the extension angle. The pulley 22 rotatably connected on the support rod 21 can assist in adjusting the position during equipment installation and commissioning. The rolling reduces frictional resistance and facilitates precise docking. The gasket 23 with threads on the top right side of the fixed plate 8, together with the limiting rod 24 passing through it, can limit the excessive rotation of the adjusting plate 9, ensuring that the interface anti-detachment structure works within the appropriate adjustment range and maintaining the reliability and stability of the overall structure.

[0037] Working principle: The hydraulic cylinder 4 is the core component of the hydraulic valve box. During operation, the piston inside the hydraulic cylinder 4 reciprocates. When the piston moves outward, a negative pressure is formed inside the hydraulic cylinder 4. At this time, the external liquid is drawn into the hydraulic cylinder 4 through the connecting pipe 5 under the action of atmospheric pressure. When the piston moves inward, the liquid inside the hydraulic cylinder 4 is compressed, the pressure increases, and the liquid is discharged through the connecting pipe 5, realizing the transmission of hydraulic force. The connecting pipe 5 is connected to the external pipe to form an interface anti-detachment structure. After the connecting pipe 5 is connected to the external pipe, its position can be adjusted by rotating the adjusting plate 9, which in turn drives the connecting rod 10 and the support plate 11 to move. The support plate 11 can abut against the external pipe. By changing the angle of the adjusting plate 9, it can provide support forces of different directions and magnitudes, and firmly fix the external pipe to the connecting pipe 5 to prevent the interface from falling off due to hydraulic impact and vibration. At the same time, the fixing plate 8 and the fixing block 12 help to enhance the stability of the structure, so that the entire anti-detachment structure can better withstand external forces.

[0038] The rotating shaft 202 passes through the connecting plate 201, and the sealing plug 206 fixedly connected to its bottom can be used to control the opening and closing of the hydraulic valve box. When sealing is required, rotating the rotating shaft 202 drives the sealing plug 206 to rotate, so that it tightly fits with the corresponding opening of the hydraulic valve box to achieve a seal and prevent liquid leakage. The fixing plate 203 is fixed to the top of the connecting plate 201, and the handle 204 is connected to the fixing plate 203 and slidably connected to the adjusting rod 205. When the rotating shaft 202 is rotated, the fixing plate 203 rotates accordingly. The lever 205 is slidably connected, and the adjusting lever 205 restricts the throttle 204 to move only in the horizontal direction. In this way, by rotating the shaft 202, the throttle 204 can slide left and right on the adjusting lever 205, thereby driving the fixed plate 203 and the connected components to adjust their positions, so as to realize the adjustment function of related components. The connecting plate 201 is connected and fixed to the anti-detachment shell 1 by bolts 207 around the perimeter, ensuring the stability of the overall structure of the control mechanism 2, so that each component can maintain a relatively fixed positional relationship during operation, and ensuring the normal operation of the control mechanism 2.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
