[0002] Hydraulic pipe joints are components that connect high-pressure oil pipes in the hydraulic system and are an important part of the hydraulic system.

[0003] When the existing pipe joint is used, the joint is rotated onto the hydraulic pipeline to connect the hydraulic pipelines together;

[0004] However, when the existing pipe joint is in use, the connection area between the joint and the pipeline is relatively small, and the hydraulic oil pressure inside the pipeline is relatively high. Therefore, the connection position between the joint and the pipeline may be washed away during operation, thereby reducing the use effect of the existing pipe joint. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a high-pressure resistant pipe joint structure, which solves the problem that when the existing pipe joint is in use, the connection area between the joint and the pipeline is relatively small and the hydraulic oil pressure inside the pipeline is relatively high. During operation, the connection position between the joint and the pipeline may be washed away, thereby reducing the use effect of the existing pipe joint.

[0006] To achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions: a high-pressure resistant pipe joint structure, including a main body, the inner wall of the main body is threadedly connected to the pipe, and a reinforcement mechanism is provided on the outside of the main body, and the reinforcement mechanism includes: a first column, fixedly connected to the outer wall of the pipe; a sleeve, rotatably connected to the inner wall of the first column through a bearing; a turntable, fixedly connected to the outer wall of the sleeve; a threaded column, threadedly connected to the inner wall of the sleeve; a second column arranged on the outside of the main body; a threaded hole, opened on the inner wall of the second column and threadedly connected to the outer wall of the threaded column; a moving assembly, arranged inside the main body; wherein, the sleeve is driven by the turntable to rotate the threaded column, and the threaded column rotates into the threaded hole, thereby strengthening the connection between the main body and the pipe and improving the high-pressure resistance of the pipe joint. Through the moving assembly, the second column drives the threaded hole to move, which facilitates the threaded column to rotate into the threaded hole.

[0007] Preferably, the moving component includes: a slide groove, which is opened on the surface of the main body; a slider, which is slidably engaged with the inner wall of the slide groove; a recessed block, which is inserted into the outer wall of the slider and fixedly connected to the top of the second column; wherein, the recessed block is driven by the second column to make the slider slide in the slide groove, drive the threaded hole to move, align with the threaded column, and facilitate the threaded column to rotate into the threaded hole.

[0008] Preferably, a rubber pad is fixedly connected to the inner wall of the sliding groove, and a side of the rubber pad away from the sliding groove is in contact with the outer wall of the sliding block.

[0009] Preferably, the concave block is fixedly connected to the inner wall of the slider by bolts.

[0010] Preferably, a sealing ring is installed on the inner wall of the body, and the inner wall of the sealing ring is in contact with the outer wall of the pipeline.

[0011] Beneficial effects

[0012] The utility model provides a high-pressure-resistant pipe joint structure. It has the following beneficial effects: the high-pressure-resistant pipe joint structure, through the cooperation among the first column, sleeve, turntable, threaded column, second column, and threaded hole, realizes a reinforced connection between the body and the pipe, improves the high-pressure resistance of the pipe joint, and solves the problem of existing pipe joints that, due to the relatively small connection area between the joint and the pipe and the relatively high hydraulic oil pressure inside the pipe, the connection between the joint and the pipe may be broken during operation, thereby reducing the use effect of the existing pipe joints.

[0013] Through the cooperation between the slider, rubber pad, slide groove, concave block and bolt, the threaded hole is moved and aligned with the threaded column, which facilitates the threaded column to rotate into the threaded hole. This solves the problem of deviation between the threaded column and the threaded hole after the body and the pipeline are connected together, making it impossible for the threaded column to rotate into the threaded hole.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] When the existing pipe joint is in use, the connection area between the joint and the pipeline is relatively small and the hydraulic oil pressure inside the pipeline is relatively high. Therefore, the connection position between the joint and the pipeline may be washed away during operation, thereby reducing the use effect of the existing pipe joint.

[0021] In view of this, the utility model provides a high-pressure resistant pipe joint structure. Through the cooperation between the first column, the sleeve, the turntable, the threaded column, the second column and the threaded hole, the connection between the reinforced body and the pipeline is realized, the high-pressure resistance of the pipe joint is improved, and the problem of the existing pipe joint being that when in use, the connection area between the joint and the pipeline is relatively small and the hydraulic oil pressure inside the pipeline is relatively high, the connection position between the joint and the pipeline may be washed away during operation, thereby reducing the use effect of the existing pipe joint.

[0022] By those skilled in the art, the components in this case are connected in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0023] Example 1, by Figure 1-4It can be seen that a high-pressure resistant pipe joint structure in this case includes a body 1, the inner wall of the body 1 is threadedly connected to the pipe 3, the staff rotates the body 1 onto the pipe 3 to connect the body 1 and the pipe 3 together, and a reinforcement mechanism 2 is provided on the outside of the body 1, and the reinforcement mechanism 2 includes: a first column 21, fixedly connected to the outer wall of the pipe 3, a sleeve 22, rotatably connected to the inner wall of the first column 21 through a bearing, a turntable 23, fixedly connected to the outer wall of the sleeve 22, the staff rotates the turntables 23 on both sides in turn, and the turntable 23 drives the sleeve 22 to rotate, a threaded column 24, threadedly connected to the inner wall of the sleeve 22, the sleeve 22 drives the threaded column 24 to move, and the threaded column 24 rotates in the sleeve 22, and a second column 25 is provided on the outside of the body 1. The threaded hole 26 is provided on the inner wall of the second column 25, and finally the threaded column 24 is rotated into the threaded hole 26 to fix the first column 21 and the second column 25 together. After completion, the staff stops rotating the turntables 23 on both sides in turn to strengthen the connection between the body 1 and the pipeline 3 and improve the high pressure resistance of the pipeline joint. The outer wall moving component 27 threadedly connected to the threaded column 24 is arranged inside the body 1, wherein the sleeve 22 is driven by the turntable 23 to rotate the threaded column 24, and the threaded column 24 is rotated into the threaded hole 26 to strengthen the connection between the body 1 and the pipeline 3 and improve the high pressure resistance of the pipeline joint. The second column 25 drives the threaded hole 26 to move by moving the component 27, which facilitates the threaded column 24 to rotate into the threaded hole 26;

[0024] During the specific implementation process, it is worth noting that first, the staff rotates the body 1 onto the pipeline 3 to connect the body 1 and the pipeline 3 together, and then the staff rotates the turntables 23 on both sides in turn, and the turntables 23 drive the sleeve 22 to rotate, and the sleeve 22 drives the threaded column 24 to move, and the threaded column 24 rotates in the sleeve 22. Finally, the threaded column 24 is rotated into the threaded hole 26 to fix the first column 21 and the second column 25 together. After completion, the staff stops rotating the turntables 23 on both sides in turn to strengthen the connection between the body 1 and the pipeline 3 and improve the high pressure resistance of the pipeline joint;

[0025] Furthermore, the moving assembly 27 includes: a slide groove 272, which is opened on the surface of the body 1, a slider 271, which is slidably engaged with the inner wall of the slide groove 272, and a concave block 273 drives the slider 271 to move. The slider 271 slides in the slide groove 272, thereby causing the second column 25 to drive the threaded hole 26 to move. The concave block 273 is inserted into the outer wall of the slider 271 and is fixedly connected to the top of the second column 25. When the body 1 is connected to the pipeline, the staff pushes the second columns 25 on both sides in turn, and the second columns 25 drive the concave block 273 to move. Among them, the concave block 273 is driven by the second column 25 to cause the slider 271 to slide in the slide groove 272, drive the threaded hole 26 to move, align with the threaded column 24, and facilitate the threaded column 24 to rotate into the threaded hole 26.

[0026] During the specific implementation process, it is worth noting that after the body 1 is connected to the pipeline, the staff pushes the second columns 25 on both sides in turn, and the second columns 25 drive the concave block 273 to move, and the concave block 273 drives the slider 271 to move, and the slider 271 slides in the slide groove 272, so that the second columns 25 drive the threaded hole 26 to move, align the threaded hole 26 with the threaded column 24, and rotate the threaded column 24 into the threaded hole 26, so as to drive the threaded hole 26 to move and align with the threaded column 24, so as to facilitate the threaded column 24 to rotate into the threaded hole 26;

[0027] Furthermore, a rubber pad 2711 is fixedly connected to the inner wall of the chute 272. When the slider 271 moves, the friction force of the rubber pad 2711 fixes the slider 271 after it moves, thereby improving the stability of the slider 271. The side of the rubber pad 2711 away from the chute 272 is in contact with the outer wall of the slider 271.

[0028] In the specific implementation process, it is worth noting that when the slider 271 moves, the friction force of the rubber pad 2711 fixes the slider 271 after it moves, thereby improving the stability of the slider 271.

[0029] After the screw thread 24 is screwed in the sleeve 22, the screw thread 24 is screwed in the sleeve 22, and the screw thread 24 is screwed in the sleeve 22. Finally, the screw thread 24 is rotated into the threaded hole 26, fixing the first column 21 and the second column 25 together. After the screw thread 24 is screwed in the sleeve 22, the screw thread 24 is screwed in the sleeve 22, and the screw thread 24 is screwed in the sleeve 22. Finally, the screw thread 24 is screwed into the threaded hole 26, fixing the first column 21 and the second column 25 together.

[0030] Example 2, by Figure 1 、 3 As shown in FIG4 , the concave block 273 is fixedly connected to the inner wall of the slider 271 by a bolt 2731 . The staff inserts the concave block 273 into the slider 271 , and then the staff rotates the bolt 2731 to fix the concave block 273 to the slider 271 .

[0031] During the specific implementation process, it is worth noting that the staff inserts the concave block 273 into the slider 271, and then the staff rotates the bolt 2731 to fix the concave block 273 to the slider 271;

[0032] Furthermore, a sealing ring 11 is installed on the inner wall of the body 1. In the specific implementation process, it is worth noting that the inner wall of the sealing ring 11 is in contact with the outer wall of the pipeline 3.

[0033] In the specific implementation process, it is worth noting that the sealing ring 11 increases the sealing between the body 1 and the pipeline 3, thereby improving the sealing effect of the body 1;

[0034] Specifically, the staff inserts the concave block 273 into the slider 271, and then rotates the bolt 2731 to fix the concave block 273 to the slider 271. The sealing ring 11 increases the sealing between the main body 1 and the pipeline 3, thereby improving the sealing effect of the main body 1.
