[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 4As shown, an integrated combination valve of an oil pressure device according to an embodiment of the present invention comprises a combination valve body 1, a connecting pipe 12 is fixedly connected to the middle part of the combination valve body 1, the outer side wall of the connecting pipe 12 is truncated, a pair of slide grooves 13 are provided in the middle part of the combination valve body 1, a slider 14 is slidably connected to the middle part of the slide groove 13, the middle part of the side wall of the slide groove 13 away from the connecting pipe 12 is inclined, the middle part of the side of the slider 14 away from the connecting pipe 12 is inclined, a guide groove 15 is provided on the side wall of the slide groove 13, a protrusion 16 is fixedly connected to the side wall of the slider 14, the protrusion 16 is slidably connected to the middle part of the guide groove 15, a screw sleeve 17 is installed in the middle part of the combination valve body 1 through a threaded connection, when working, the screw sleeve 17 is first put on the hose to be connected, and then the end of the hose is put on the middle part of the connecting pipe 12 and inserted in the direction of the combination valve body 1, and then the screw sleeve 17 is installed in the middle part of the combination valve body 1 through threaded matching and The screw sleeve 17 moves toward the slider 14. Through the squeezing of the screw sleeve 17 on the slider 14, a pair of sliders 14 will slide inward, and under the cooperation of the inclined surface between the slide groove 13 and the slider 14, the slider 14 moves toward the end of the hose sleeve in the middle of the connecting pipe 12 and squeezes the end of the hose. As the screw sleeve 17 continues to rotate to make the slider 14 continue to move, the end of the hose will be driven by the slider 14 to move due to the friction between it and the slider 14, so that the hose and the connecting pipe 12 are more tightly combined. After the connection of the hose is completed, the squeezing of the hose by the slider 14 increases the friction between the hose and the middle part of the connecting pipe 12, thereby reducing the occurrence of the hose falling off. Through the above structure, when the hose and the combination valve body 1 are connected, the connection between the combination valve body 1 and the hose can be made tighter, reducing the occurrence of the hose falling off and reducing the occurrence of liquid leakage to a certain extent.

[0024] like Figures 1 to 2 As shown, a groove 2 is provided on the side wall of the slider 14, and an elastic rope 21 is fixedly connected to the middle of the groove 2. The other end of the elastic rope 21 is fixedly connected to the middle of the combination valve body 1. During operation, when the connecting pipe 12 and the hose are connected, no matter what angle the combination valve body 1 is at, even if the port direction of the connecting pipe 12 is facing downward, the slider 14 will stay at a position close to the outer side wall of the combination valve body 1 due to the elastic rope 21, so that there is enough distance between the slider 14 and the connecting pipe 12 for the hose to be initially connected to the connecting pipe 12. Through the above structure, the situation where the slider 14 slides randomly and causes obstacles to the connection between the hose and the connecting pipe 12 can be reduced, thereby improving the convenience of use of the device.

[0025] like Figures 1 to 3As shown, the middle part of the screw sleeve 17 is rotatably connected with the sleeve 3, and the sleeve 3 is arranged inside the screw sleeve 17. During operation, when the screw sleeve 17 is rotated to squeeze the slider 14, the sleeve 3 will replace the screw sleeve 17 to contact the side wall of the slider 14, thereby reducing the wear on the surface of the slider 14 when the screw sleeve 17 rotates, improving the service life of the slider 14, and reducing the occurrence of a decrease in the hose connection effect caused by the reduction in length of the slider 14 due to wear.

[0026] like Figures 1 to 3 As shown, the inner wall of the sleeve 3 is fixed with an inclined block 4, and the inclined block 4 has the same inclination angle as the outer wall of the connecting pipe 12. During operation, as the screw sleeve 17 rotates and moves toward the inside of the combined valve body 1, the inclined block 4 will gradually approach the inclined surface in the middle of the connecting pipe 12. Finally, the inclined block 4 and the connecting pipe 12 will squeeze the hose in the middle, further improving the bonding between the hose and the connecting pipe 12, reducing the occurrence of the hose falling off, and further improving the sealing between the hose and the connecting pipe 12, reducing the occurrence of leakage.

[0027] like Figures 1 to 3 As shown, a rubber pad 5 is fixed to the middle of the inclined block 4, and the rubber pad 5 is arranged on the side of the inclined block 4 facing the connecting pipe 12. When working, the rubber pad 5 and the hose will be squeezed in the middle by the inclined block 4 and the connecting pipe 12. Through the dual elastic deformation of the rubber pad 5 and the hose, the reverse force on the screw sleeve 17 is increased, and the friction between the screw sleeve 17 and the thread of the combination valve body 1 is increased, thereby reducing the loosening of the screw sleeve 17 due to the vibration of the device, and further reducing the occurrence of the hose falling off.

[0028] like Figures 1 to 4 As shown, a plurality of engaging teeth 6 are fixedly connected to the side of the slider 14 facing the connecting pipe 12, and the plurality of engaging teeth 6 are evenly distributed on the side wall of the slider 14. Through the above structure, the friction between the slider 14 and the hose can be further increased, so that the hose can be driven by the slider 14 to move a longer distance, thereby improving the bonding between the hose and the connecting pipe 12 and reducing the occurrence of the hose falling off.

[0029] like Figure 3 As shown, a plurality of anti-slip grooves 7 are provided in the middle of the screw sleeve 17. The plurality of anti-slip grooves 7 are distributed in a circular array in the middle of the screw sleeve 17. Through the above structure, the friction between the screw sleeve 17 and the hand can be increased when the screw sleeve 17 is rotated, so that the screw sleeve 17 can be tightened conveniently, thereby further reducing the occurrence of the hose falling off.

[0030] When working, first put the screw sleeve 17 on the hose that needs to be connected, and then put the hose end on the middle part of the connecting pipe 12 and insert it in the direction of the combined valve body 1, and then install the screw sleeve 17 in the middle part of the combined valve body 1 through threaded engagement and move the screw sleeve 17 toward the direction of the slider 14. Through the squeezing of the slider 14 by the screw sleeve 17, a pair of sliders 14 will slide inward, and under the cooperation of the inclined surface between the slide groove 13 and the slider 14, the slider 14 will move toward the hose end part sleeved in the middle part of the connecting pipe 12 and squeeze the hose end part. As the screw sleeve 17 continues to rotate to make the slider 14 continue to move, the hose end will be driven by the slider 14 to move due to the friction between the slider 14, so that the hose and the connecting pipe 12 are more tightly combined. After completing the connection of the hose, the friction between the hose and the middle part of the connecting pipe 12 is increased due to the squeezing of the hose by the slider 14, thereby reducing the occurrence of the hose falling off. When the pipes are connected, no matter what angle the combination valve body 1 is at, even if the port direction of the connecting pipe 12 is facing downward, the slider 14 will stay in a position close to the outer wall of the combination valve body 1 due to the elastic rope 21, so that there is enough distance between the slider 14 and the connecting pipe 12 for the hose to be initially connected to the connecting pipe 12. When the screw sleeve 17 is rotated to squeeze the slider 14, the sleeve 3 will replace the screw sleeve 17 and contact the side wall of the slider 14, thereby reducing the wear on the surface of the slider 14 when the screw sleeve 17 rotates. In the process of the screw sleeve 17 rotating and moving toward the inside of the combination valve body 1, the inclined block 4 will gradually approach the inclined surface in the middle of the connecting pipe 12. Finally, the inclined block 4 and the connecting pipe 12 will squeeze the hose in the middle, and the rubber pad 5 will be squeezed in the middle together with the hose by the inclined block 4 and the connecting pipe 12. Through the dual elastic deformation of the rubber pad 5 and the hose, the reverse force on the screw sleeve 17 is increased, and the friction between the screw sleeve 17 and the thread of the combination valve body 1 is increased.
