[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0024] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0025] Embodiment 1: As Figure 1 - Figure 6 shown, the present utility model provides a crimped hydraulic pipe joint, including a joint body 1. An anti-loosening mechanism 2 is arranged on the outer surface of the joint body 1. A hydraulic pipe 3 is arranged inside the joint body 1. The hydraulic pipe 3 is slidably connected to the joint body 1. An installation groove 4 is formed on the outer surface of the hydraulic pipe 3. A fixed shell 5 is fixedly connected to the outer surface of the joint body 1. A movable plate 6 is slidably connected inside the fixed shell 5. One side of the movable plate 6 is fixedly connected with a pull rod 7. The other side of the movable plate 6 is fixedly connected with a positioning block 8. One side of the positioning block 8 movably penetrates through the fixed shell 5 and extends into the installation groove 4. One end of the pull rod 7 movably penetrates through the fixed shell 5. A return spring 9 is sleeved on the outer surface of the pull rod 7.

[0026] The effect achieved by the entire Embodiment 1 is that when connecting through the joint body 1 and the hydraulic pipe 3, the hydraulic pipe 3 is inserted into the joint body 1. When the hydraulic pipe 3 slides inside the joint body 1, it will squeeze the positioning block 8 to drive the positioning block 8 to move. The positioning block 8 will compress the return spring 9 through the movable plate 6, and the positioning block 8 will shrink into the fixed shell 5. When the installation groove 4 on the hydraulic pipe 3 moves to the positioning block 8, the pressure on the return spring 9 disappears. Under the elastic force of the return spring 9, the return spring 9 drives the positioning block 8 to insert into the installation groove 4 through the movable plate 6, thereby limiting and fixing the hydraulic pipe 3, facilitating the connection between the hydraulic pipe 3 and the joint body 1. Thus, when connecting the joint body 1 and the hydraulic pipe 3, only by pushing the hydraulic pipe 3 and inserting the hydraulic pipe 3 into the joint body 1 can the hydraulic pipe 3 and the joint body 1 be connected and fixed well, which is simple, convenient, time-saving and labor-saving.

[0027] Embodiment 2: As Figure 1 - Figure 6 shown, the anti-loosening mechanism 2 includes a connecting frame 201, the connecting frame 201 is fixedly connected to the outer surface of the joint body 1, a threaded hole 202 is opened on one side of the connecting frame 201, a fastening knob 203 is threadedly connected in the threaded hole 202, a card slot 204 is opened on the fastening knob 203, a sealing gasket 10 is fixedly connected to the top end of the joint body 1, a support spring 11 is arranged inside the sealing gasket 10, a sleeve 12 is sleeved on the outer surface of the joint body 1, the sleeve 12 is of a hollow structure, a tapered pipe 13 is arranged at the bottom end of the joint body 1, one end of the pull rod 7 is fixedly connected with a pull plate 14, a sliding groove 15 is opened on the inner side of the fixed shell 5, a slider 16 is slidably connected in the sliding groove 15, one side of the slider 16 is fixedly connected with the movable plate 6, and the outer surface of the positioning block 8 is inclined.

[0028] The effect achieved by the entire Embodiment 2 is that by providing an anti-loosening mechanism 2, the card slot 204 can be clamped with a screwdriver. After clamping, the fastening knob 203 can be rotated. Under the action of the thread, until the fastening knob 203 abuts against the hydraulic pipe 3, an anti-loosening effect is achieved, improving the connection stability. Further, under the action of the support spring 11, the gasket 10 can be closely attached to the hydraulic pipe 3. Moreover, the gasket 10 is made of rubber material, which can improve the sealing performance at the connection between the joint body 1 and the hydraulic pipe 3. Then, the sleeve 12 is inserted outside the pipe, and then the joint body 1 is inserted inside the pipe. Then, the sleeve 12 is pressed by a press, facilitating the clamping of the sleeve 12 to the pipe. The tapered pipe 13 plays a guiding role, facilitating the insertion of the joint body 1 inside the pipe. Further, by providing the pull plate 14, it is convenient to pull the pull rod 7. By pulling the pull plate 14, the pull rod 7 drives the movable plate 6 to move. The movable plate 6 drives the positioning block 8 to move and separate from the installation groove 4, facilitating the disassembly of the hydraulic pipe 3. Further, when the movable plate 6 moves, the movable plate 6 drives the slider 16 to slide synchronously in the chute 15, improving the stability of the movable plate 6 during movement. Further, the outer surface of the positioning block 8 is inclined, facilitating the extrusion of the positioning block 8 by the hydraulic pipe 3 when the hydraulic pipe 3 slides inside the joint body 1, driving the positioning block 8 to move.

[0029] Working principle: During installation, the sleeve 12 can be inserted outside the pipe, and then the joint body 1 is inserted inside the pipe. Then, the sleeve 12 is pressed by a press until the sleeve 12 clamps the pipe. Subsequently, the hydraulic pipe 3 is inserted into the joint body 1. When the hydraulic pipe 3 slides inside the joint body 1, it will squeeze the positioning block 8 to drive the positioning block 8 to move. The positioning block 8 compresses the return spring 9 through the movable plate 6, and the positioning block 8 will contract into the fixed housing 5. When the installation groove 4 on the hydraulic pipe 3 moves to the positioning block 8, the pressure on the return spring 9 disappears. Under the elastic force of the return spring 9, the return spring 9 drives the positioning block 8 to insert into the installation groove 4 through the movable plate 6, thereby limiting and fixing the hydraulic pipe 3, facilitating the connection between the hydraulic pipe 3 and the joint body 1, which is simple, convenient, time-saving and labor-saving. At the same time, the card slot 204 can be clamped with a screwdriver. After clamping, the fastening knob 203 can be rotated. Under the action of the thread, until the fastening knob 203 abuts against the hydraulic pipe 3, an anti-loosening effect is achieved, further improving the connection stability.

[0030] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
