DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 In order to solve the problem that the existing hydraulic control valve usually needs to use bolts, nuts and other fasteners to connect with the pipeline, so that the operation of disassembling and installing the pipeline is cumbersome, the labor cost is high, and it is time-consuming and labor-intensive during installation and maintenance, the following preferred technical solutions are provided:

[0022] A quick-connect device for a hydraulic control valve comprises a control valve body 1, and a first connecting pipe 2 and a second connecting pipe 3 arranged on both sides of the control valve body 1. The first connecting pipe 2 and the second connecting pipe 3 have the same composition structure. The upper walls of the first connecting pipe 2 and the second connecting pipe 3 are both provided with a quick-connect assembly 4. The quick-connect assembly 4 comprises a control block 41 and a movable groove 42 opened on the upper wall of the first connecting pipe 2. The lower end of the control block 41 is fixedly connected to a threaded rod 43, the outer wall of the threaded rod 43 is threadedly connected to a movable block 44, the lower end of the movable block 44 is fixedly connected to a fixed block 45, and both sides of the movable block 44 are slidably connected to the inner wall of the movable groove 42.

[0023] The fixed block 45 is hemispherical in shape and is a component made of rubber material. A return spring 46 is provided in the inner cavity of the fixed block 45 . One end of the return spring 46 is fixedly connected to the bottom plate in the cavity of the fixed block 45 , and the other end of the return spring 46 is fixedly connected to the top plate in the cavity of the fixed block 45 .

[0024] The inner walls of the first connecting pipe 2 and the second connecting pipe 3 at the pipe openings are fixedly installed with sealing components 5, which fit the inner walls of the pipe openings. The sealing components 5 include a rubber ring 51 that fits the inner walls of the pipe openings. A buffer cavity 52 is provided inside the rubber ring 51. An elastic element 53 is fixedly connected inside the buffer cavity 52. ​​The elastic element 53 is U-shaped. There are multiple groups of elastic elements 53, and the multiple groups of elastic elements 53 are distributed around the center of the rubber ring 51.

[0025] Specifically, when connecting the pipeline, the first pipe 2 and the second pipe 3 are directly aligned with the pipeline, and the pipeline is inserted into the pipe openings of the first pipe 2 and the second pipe 3. At this time, the control block 41 is rotated, and the control block 41 is used to drive the threaded rod 43 to rotate. When the threaded rod 43 rotates, it will drive the movable block 44 to move downward on the inner wall of the movable groove 42, and drive the fixed block 45 to press the inserted pipeline downward to complete the fixation. When the fixed block 45 presses the inserted pipeline downward, the fixed block 45 is subjected to the reaction force, and its own lower wall is recessed into the cavity, thereby compressing the return spring 46. At this time, through the self-recovery of the fixed block 45 and the reaction force of the return spring 46, the compression effect of the fixed block 45 is further improved, and the connection is improved. The stability, the connection is extremely convenient, time-saving and labor-saving, and the existing hydraulic control valve usually needs to use bolts, nuts and other fasteners to connect with the pipeline, so that during installation and maintenance, the operation of disassembling and installing the pipeline is relatively cumbersome, the labor cost is high, and it is time-consuming and labor-intensive.

[0026] When the pipe is inserted into the pipe openings of the first connecting pipe 2 and the second connecting pipe 3, the pipe will squeeze the rubber ring 51, driving the buffer chamber 52 to squeeze the elastic element 53. By utilizing the organic cooperation between the elastic element 53 and the buffer chamber 52, the rubber ring 51 is driven to fit the pipe, which not only improves the stability of the connection, but also ensures the sealing.

[0027] To sum up: align the first connecting pipe 2 and the second connecting pipe 3 with the pipeline, and insert the pipeline into the pipe openings of the first connecting pipe 2 and the second connecting pipe 3. At this time, rotate the control block 41, and use the control block 41 to drive the threaded rod 43 to rotate. When the threaded rod 43 rotates, it will drive the movable block 44 to move downward on the inner wall of the movable groove 42, and drive the fixed block 45 to press the inserted pipeline downward to complete the fixation. When the fixed block 45 presses the inserted pipeline downward, the fixed block 45 is subjected to the reaction force, and its own lower wall is recessed into the cavity, thereby compressing the reset spring 46. At this time, through the self-recovery of the fixed block 45 and the reaction force of the reset spring 46, the compression effect of the fixed block 45 will be further improved, and the stability of the connection will be improved. When the pipeline is inserted into the pipe openings of the first connecting pipe 2 and the second connecting pipe 3, the pipeline will squeeze the rubber ring 51, drive the buffer cavity 52 to squeeze the elastic element 53, and use the organic cooperation between the elastic element 53 and the buffer cavity 52 to drive the rubber ring 51 to fit the pipeline.
