[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 - Figure 3 FIG., an embodiment provided by the present utility model: A quickly fixed reinforced concrete steel socket pipe includes a pipeline 1, and there are two groups of pipelines 1. The two groups of pipelines 1 are reinforced concrete socket pipes in the prior art. Two left and right positioning blocks 3 are fixedly connected to the surface of the left pipeline 1, and a positioning assembly 2 is arranged on the inner wall of the right pipeline 1.

[0033] Refer to Figure 2 And Figure 3, the positioning component 2 includes a threaded rod 21. There are two groups of threaded rods 21, and the two groups of threaded rods 21 are rotatably connected to both sides of the outer wall of the pipe 1. The plug rod 23 penetrates and is slidably connected to the inner wall of the threaded rod 21. Guide grooves that fit the two sides of the plug rod 23 are provided on the inner wall of the threaded rod 21, so that when the threaded rod 21 rotates, it will also drive the plug rod 23 to rotate synchronously with it. And a handle is provided on the surface of the threaded rod 21 for convenient rotation operation. The outer wall of the threaded rod 21 is elastically connected to the plug rod 23 through a limiting spring 22. One end of the limiting spring 22 is fixedly connected to the outer wall of the top of the threaded rod 21, and the other end of the limiting spring 22 is fixedly connected to the inner side wall of the plug rod 23. The function of the limiting spring 22 is to automatically reset the position of the plug rod 23 after it is pulled outwards. The plug rod 23 penetrates and is slidably connected to the inner wall of the right pipe 1. Two groups of positioning grooves are provided on the surface of the right pipe 1. The outer wall of the positioning block 3 is in contact with the inner wall of the positioning groove. By providing a positioning groove on the surface of the right pipe 1 that fits the positioning block 3, the two pipes 1 can be quickly positioned and fixed.

[0034] Refer to Figure 2 and Figure 3 , through holes are provided on the outer wall of the positioning block 3, and the plug rod 23 is inserted into the inner wall of the through hole. The insertion between the two can preliminarily fix the position of the positioning block 3 inserted into the inner wall of the right pipe 1 through the plug rod 23, thus facilitating subsequent reinforcement installation. A sliding sleeve 26 is threadedly connected to the surface of the threaded rod 21. Hinge rods 24 are hinged to both sides of the outer wall of the sliding sleeve 26. One end of the hinge rod 24 away from the sliding sleeve 26 is hinged to a plug block 25. Internal threads that fit the outer wall of the threaded rod 21 are provided on the inner wall of the sliding sleeve 26, so that when the threaded rod 21 rotates, the sliding sleeve 26 will move back and forth on its surface, and the corresponding plug blocks 25 can be synchronously pushed closer to or away from each other through the two hinge rods 24, so as to insert the empty groove at the top of the positioning block 3. The plug block 25 is slidably connected to the inner walls on both sides of the pipe 1. Empty grooves are provided on the upper and lower outer walls of the positioning block 3, and the plug block 25 is inserted into the inner wall of the empty groove. The insertion between the two makes the positioning block 3 that enters the inner wall of the right pipe 1 be secondarily reinforced by the plug block 25 after being preliminarily positioned by the plug rod 23, making the connection stability between the two better. A sealing ring 4 is detachably installed on the surface of the pipe 1 through a support component 5. The sealing ring 4 is a prior art. By providing a sealing ring 4 on the surfaces of the two pipes 1, the sealing effect at the connection can be increased, and water leakage from the connection due to insufficient tightness can be prevented.

[0035] Refer to Figure 3 and Figure 4, the support component 5 includes a support block 51. The bottom end of the outer wall of the support block 51 is elastically connected to the inner wall of the surface of the pipe 1 through a return spring 52. One end of the return spring 52 is fixedly connected to the bottom end of the outer wall of the support block 51, and the other end of the return spring 52 is fixedly connected to the inner wall of the pipe 1. The function of the return spring 52 is to apply an elastic support to the support block 51 when it is sleeved by the sealing ring 4 on the outside. The support block 51 is slidably connected to the inner wall of the surface of the pipe 1. A guide rod 53 penetrates and is slidably connected to the inner wall of the support block 51. By providing the guide rod 53, the support block 51 can be guided when it descends. The guide rod 53 is fixedly connected to the inner wall of the pipe 1. The surface of the support block 51 is in contact with the inner side wall of the sealing ring 4. The contact between the two can support sealing rings 4 of different sizes, avoiding the need for manual support of the sealing ring 4 to install and lock the two pipes 1 together.

[0036] Working principle: There are two sets of left and right positioning blocks 3 fixedly connected to the surface of the left pipe 1. When connecting the two pipes 1, insert the positioning block 3 on the left pipe 1 into the inner wall of the right pipe 1. There are two sets of positioning grooves on the surface of the right pipe 1. The outer wall of the positioning block 3 is in contact with the inner wall of the positioning groove. Through this design, the two pipes 1 can be quickly positioned and fixed. At the same time, pull out the insertion rod 23 outward and let the limiting spring 22 be elastically compressed. After the positioning block 3 is inserted into the inner wall of the right pipe 1, release the insertion rod 23, and it will be elastically affected by the limiting spring 22 to insert the insertion rod 23 into the inner wall of the through hole. Through this insertion method, the positioning block 3 can be initially fixed after being inserted into the inner wall of the right pipe 1, facilitating subsequent reinforcement installation. After the two pipes 1 are initially fixed, by rotating, when the threaded rod 21 rotates, the sliding sleeve 26 will move back and forth on its surface. When the sliding sleeve 26 moves on the surface of the threaded rod 21, it will synchronously push the corresponding insertion blocks 25 to approach each other through two hinge rods 24. There are empty grooves on the upper and lower outer walls of the positioning block 3, and the insertion blocks 25 are inserted into the inner walls of the empty grooves. After the positioning block 3 is initially positioned by the insertion rod 23, the insertion blocks 25 will reinforce the positioning block 3 a second time, making the connection stability between the two better.

[0037] When the outside of the support block 51 is sleeved by the sealing ring 4, sealing rings 4 of different sizes will, due to their own rubber deformation effect, push the support block 51 to move downward on the surface of the guide rod 53 and compress the return spring 52. At the same time, the return spring 52 can apply an elastic support to it. Through this contact method, sealing rings 4 of different sizes can be supported, avoiding the need for manual support of the sealing ring 4 to install and lock the two pipes 1 together.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
