[0002] In construction or municipal construction, drainage through drain pipes is a common method. Existing drain pipes are made of various materials, including PVC, PPR, copper pipes, and composite pipes. Pipe connection calibration devices are devices used to ensure the accuracy and stability of pipes when connected. This device is often used in the process of manufacturing and installing pipe systems to ensure that the quality of pipe connections meets standards and specifications. This device usually includes a series of clamps, holders, or fixtures to maintain the position and direction of the pipe so that the connector can be accurately installed at the end of the pipe. They can also include some measuring and calibration equipment to ensure that the position and angle of the connector meet the requirements.

When connecting PVC pipes, there are also many ways such as hot melting and gluing, but because the wall of PVC pipes is thin, if the axis is offset during connection, it is easy to cause gaps in the connection part, making the connection unstable.

[0026] like Figure 1-Figure 6As shown, the utility model provides a technical solution: a pipeline connection auxiliary calibration device, including a calibration bracket 1, a positioning part 2 and an auxiliary part 3 are arranged on the inner side of the calibration bracket 1, and the positioning part 2 includes: a positioning ring 21, a screw rod 22, an auxiliary slider 23, a support rod 24, a positioning block 25, a spring 1 26, an insertion rod 27, a fixing column 28, a transmission column 29, a transmission bar 210, a chuck 211, a clamping hole 212, a handle 213, a grip rod 214, a spring 215, an arc guide rod 216, and an arc spring 217.
[0027] The surface of the positioning ring 21 is fixedly connected to the inner side of the calibration bracket 1, and the surface of the positioning ring 21 is penetrated and threadedly connected with a screw 22, which pushes the auxiliary slider 23 to slide along the inner wall of the positioning ring 21, so that the auxiliary slider 23 pushes the positioning block 25 to position the PVC drain pipe through a spring 26, and the bottom end of the screw 22 is penetrated and rotatably connected with the auxiliary slider 23, and when the chuck 211 rotates, the fixed column 28 is driven to rotate through the transmission column 29 and the transmission bar 210, and then the fixed column 28 is rotated. The rotation of the fixed column 28 will gradually screw the screw rod 22 into the positioning ring 21, and the screw rod 22 will push the auxiliary slider 23 to slide along the inner wall of the positioning ring 21. The top of the support rod 24 passes through the auxiliary slider 23 and is slidably connected. The bottom end of the support rod 24 is fixedly connected with a positioning block 25. When the positioning block 25 contacts the surface of the PVC drain pipe, the positioning block 25 is subjected to a reaction force to push the support rod 24 to insert into the inner side of the auxiliary slider 23. The top surface of the positioning block 25 is fixedly connected with a spring 26. The top of the spring 26 The end is fixedly connected to the bottom surface of the auxiliary slider 23, the bottom surface of the insertion rod 27 is fixedly connected to the top surface of the positioning block 25, the top of the screw rod 22 is fixedly connected with a fixed column 28, grab the gripping rod 214 and rotate it, and the gripping rod 214 will drive the chuck 211 to rotate through the handle 213, and when the chuck 211 rotates, it will drive the fixed column 28 to rotate through the transmission column 29 and the transmission bar 210. The top of the fixed column 28 is penetrated by the transmission column 29, and the inner side of the transmission column 29 is fixedly connected with the transmission bar 210. The strip 210 penetrates the fixed column 28, and the surface of the chuck 211 is penetrated and fixedly connected by the transmission column 29. The surface of the chuck 211 is provided with a clamping hole 212. As the screw 22 is screwed into the positioning ring 21, the distance between the chuck 211 and the insertion rod 27 is gradually shortened and the insertion rod 27 is gradually inserted into the clamping hole 212, so that the chuck 211 cannot continue to rotate. At that time, the positioning block 25 has aligned the axis of the PVC drain pipe, and the PVC drain pipe will not be deformed due to excessive clamping force. The top surface of the chuck 211 is fixedly connected with a handle 213, and the top surface of the handle 213 is penetrated and rotatably connected with a grip rod 214. Grab the grip rod 214 and rotate it, and the grip rod 214 will drive the chuck 211 to rotate through the handle 213. The top surface of the fixed column 28 is fixedly connected with a spring 215, and the top surface of the spring 215 is fixedly connected to the inner wall of the transmission column 29. When the limit is released, the handle 213 is pulled upward, so that the locking hole 212 is driven by the transmission column 29 to no longer allow the insertion rod 27 to be inserted into the locking hole 212. The insertion rod 27 penetrates the positioning ring 21 and the auxiliary slider 23 at the same time, and the insertion rod 27 is slidably connected with the positioning ring 21 and the auxiliary slider 23. The positioning block 25 is subjected to a reaction force to push the support rod 24 to insert into the inner side of the auxiliary slider 23, and the distance between the auxiliary slider 23 and the positioning block 25 is shortened, so that the insertion rod 27 moves upward relatively.There are three groups of auxiliary sliders 23, and an arc-shaped guide rod 216 is inserted between every two groups of auxiliary sliders 23, and an arc-shaped spring 217 is fixedly connected between every two groups of auxiliary sliders 23. The auxiliary part 3 includes a square column 31, the bottom surface of the square column 31 is fixedly connected to the top surface of the calibration bracket 1, the top of the square column 31 is penetrated and slidably connected by a square rod 32, and the top surface of the square rod 32 is fixedly connected to a bracket 33. When docking the PVC drainage pipe of the building, the PVC drainage pipe is first manually placed on the bracket 33 for lifting, and then the PVC drainage pipe is pushed into the positioning ring 21, and the docking end of the PVC drainage pipe is placed between the two groups of positioning rings 21. A spring 35 is fixedly connected between the bottom end of the square rod 32 and the inner wall of the square column 31, and a roller 34 is penetrated and rotatably connected to the inner side of the bracket 33.

When the positioning block 25 contacts the surface of the PVC drain pipe, the positioning block 25 is subjected to a reaction force to push the support rod 24 to insert into the inner side of the auxiliary slider 23, and the distance between the auxiliary slider 23 and the positioning block 25 is shortened, so that the insertion rod 27 moves upward relatively. Because the screw rod 22 is screwed into the positioning ring 21, the distance between the chuck 211 and the insertion rod 27 is gradually shortened and the insertion rod 27 is gradually inserted into the clamping hole 212, so that the chuck 211 cannot continue to rotate. At that time, the positioning block 25 has aligned the axis of the PVC drain pipe, and the PVC drain pipe will not be deformed due to excessive clamping force. When the limit is released, the handle 213 is pulled upward, thereby driving the clamping hole 212 through the transmission column 29 to no longer allow the insertion rod 27 to be inserted into the clamping hole 212.
[0029] By means of the symmetrical positioning ring 21 and three groups of auxiliary sliders 23 and positioning blocks 25 arranged in a circular array, the connecting edges of the two groups of PVC drain pipes can be kept aligned while the axes can also be kept consistent, preventing the PVC drain pipes from having gaps in the connection position due to axis deviation when connected, and the roller 34 on the inner side of the bracket 33 can assist the PVC drain pipe to enter the positioning ring 21.
[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
