Technical Field
[0001] This utility model relates to the field of connection structure technology, specifically a drainage pipe connection structure. Background Technology
[0002] Drainage pipelines refer to the system of pipes and their ancillary facilities that collect and discharge sewage, wastewater, and rainwater. This includes main pipes, branch pipes, and pipes leading to treatment plants. Regardless of whether they are built on streets or anywhere else, any pipe that serves a drainage function should be counted as a drainage pipeline.
[0003] In the process of realizing this utility model, the inventors discovered that the following problems in the prior art have not been solved: In the existing drainage pipe connection process, the pipes are mostly placed on the ground, but the flange diameter is larger than the pipe diameter, and the pipe is inclined. In order to make it horizontal, it is necessary to send someone else to straighten the pipe. It is quite laborious for a single person to complete this task. Therefore, we propose a drainage pipe connection structure. Utility Model Content
[0004] The purpose of this utility model is to provide a drainage pipe connection structure that solves the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a drainage pipe connection structure, including a bracket, wherein slide rails are installed on the top of both sides of the bracket, and support blocks are provided on the top of the slide rails;
[0006] The slide rail has a movable locking position in the middle, and the top of the slider is fixedly connected to the support block.
[0007] The top of the support block has a pipe opening, and the bottom of the support block has an arc-shaped groove. Several sets of annular array bead grooves are formed in the arc-shaped groove, and rolling balls are movably positioned in the bead grooves.
[0008] A tube is placed inside the ball bearing of the arc groove. A flange is fixedly installed at one end of the tube, and the flange is positioned inside the support block, with the two flanges fitting together.
[0009] The bracket has ear plates fixedly installed on both sides of the bottom, and the ear plates have positioning holes in the middle. It can be used in conjunction with components such as arc grooves, ball bearings and brackets. During the use of the connection structure, the two sets of pipes are placed into the ball grooves through the pipe openings, and the flanges are located inside the support block. The flanges on both sides are close together, and the support block can play a role in limiting the pipe. Then, force is applied to rotate the pipes so that the bolt holes of the flanges are aligned. Then, the bolts are assembled. This structure is used for temporary support and limiting of pipes, which facilitates the disassembly and assembly of multiple sets of bolts. The pipe connection can be completed by a single person. The setting of ball bearings and ball grooves makes the rotation of the pipes less strenuous.
[0010] As an optional solution to the technical solution of this application, a screw rod is movably inserted through one side of the slide rail. The screw rod is screwed into a pre-set screw hole in the slider through an external thread. The inner end of the screw rod is rotatably connected to the inner wall of the slide rail through a bearing. The slide rail and screw rod can be used together. By applying force to rotate the screw rod, the slider can move laterally within the slide rail. The slider can then drive the support block to move. The distance between the two sets of support blocks can be adjusted according to the flange thickness of the drainage pipe. It has a wide range of applications and strong versatility.
[0011] As an optional solution to the technical solution of this application, reinforcing ribs are fixedly installed at both corners inside the bracket, and the reinforcing ribs are triangular in structure. The reinforcing ribs can improve the connection rigidity to prevent tearing and breakage.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] Please see Figure 1-3 This utility model provides a technical solution: a drainage pipe connection structure, including a bracket 1. Reinforcing ribs 12 are fixedly installed at both corners of the bracket 1. The reinforcing ribs 12 are triangular in structure, which can improve the connection rigidity and prevent tearing or breakage. Slide rails 2 are installed on the top of both sides of the bracket 1. Support blocks 3 are provided on the top of the slide rails 2. An indicator sign 31 is fixedly installed on the front wall of a set of support blocks 3, and the indicator sign 31 is fixed by welding. The guiding text on the indicator sign 31 can inform the operator of the corresponding procedures, facilitating understanding and use. A slider 21 is movable in the middle of the rail 2, and the top of the slider 21 is fixedly connected to the support block 3; a pipe opening 33 is opened at the top of the support block 3, and an arc groove 32 is opened at the bottom of the support block 3. Several sets of annular array of ball grooves 34 are opened in the arc groove 32, and a ball 35 is movable in the ball groove 34; a tube 4 is placed inside the ball 35 in the arc groove 32, and a flange 41 is fixedly installed at one end of the tube 4. The flange 41 is locked inside the support block 3, and the two sets of flanges 41 are in contact; ear plates 11 are fixedly installed on both sides of the bottom of the bracket 1, and a positioning hole is opened in the middle of the ear plate 11.
[0024] In this technical solution, components such as the arc groove 32, ball bearings 35, and bracket 1 can be used together. During the use of the connection structure, the two sets of pipe bodies 4 are respectively placed into the ball groove 34 through the pipe opening 33, and the flange 41 is located inside the support block 3. The two flanges 41 are in contact with each other, and the support block 3 can play a role in limiting the pipe. Then, force is applied to rotate the pipe body 4 so that the bolt holes of the flange 41 are aligned. Then, the bolts are assembled. This structure is used for temporary support and limiting of the pipe, which is convenient for disassembling and assembling multiple sets of bolts. The connection of the pipe can be completed by a single person. Moreover, the setting of the ball bearings 35 and the ball groove 34 makes the rotation of the pipe body 4 less strenuous.
[0025] In some technical solutions, a screw 23 is movably inserted through one side of the slide rail 2, and a rotating block 24 is fixedly installed at the outer end of the screw 23. The outer wall of the rotating block 24 is provided with anti-slip texture. Whenever the adjusting screw 23 is rotated, it can be adjusted by holding the rotating block 24, which is convenient for applying force. The screw 23 is screwed into the screw hole in the slider 21 through the external thread, and the inner end of the screw 23 is rotatably connected to the inner wall of the slide rail 2 through the bearing 22.
[0026] In this technical solution, components such as slide rail 2 and screw 23 can be used together. By applying force to rotate screw 23, the slider 21 can move laterally within slide rail 2. Slider 21 can then drive support block 3 to move. The distance between the two sets of support blocks 3 can be adjusted according to the thickness of flange 41 of the drainage pipe. It has a wide range of applications and strong versatility.
[0027] Working principle: It should be noted that this utility model is a drainage pipe connection structure. All components are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional test methods.
[0028] When a drainage pipe connection structure is used, the connection structure is placed in the drainage pipe connection area, and then the connection structure is fixed to the support through the ear plate 11. After the two sets of drainage pipe bodies 4 are placed in place, the connection operation is carried out by through bolts.
[0029] By incorporating an arc-shaped groove 32, ball bearings 35, and a support 1, during the connection process, two sets of pipe bodies 4 are placed into the ball bearing groove 34 through the pipe opening 33, with the flange 41 positioned inside the support block 3. The flanges 41 on both sides are in contact, and together with the support block 3, they can limit the pipe movement. Then, force is applied to rotate the pipe body 4, aligning the bolt holes of the flange 41, and then the bolts are assembled. This structure is used for temporary support and limiting of pipes, facilitating the installation and removal of multiple sets of bolts. Pipe connection can be completed by a single person. The ball bearings 35 and the ball bearing groove 34 make the rotation of the pipe body 4 less strenuous. With the inclusion of a slide rail 2 and a screw 23, force is applied to rotate the screw 23. The rotation of the screw 23 causes the slider 21 to move laterally within the slide rail 2, which in turn moves the support block 3. The distance between the two sets of support blocks 3 can be adjusted according to the thickness of the flange 41 of the drainage pipe. This structure has a wide range of applications and strong versatility.
