Description

Technical Field

[0001] This utility model belongs to the field of pipeline inspection technology, specifically a quick water supply connector. Background Technology

[0002] Various pipelines are installed inside the factory area to ensure the supply of water and sewage for production. After the pipelines are connected, a leak test is required. The leak test involves flushing a set amount of water into the pipeline and checking whether there are any leaks at the joints. This is an essential procedure in pipeline inspection.

[0003] Pipeline leak testing is a phased operation. For example, a 30-meter pipeline is considered as a phase, and then the pipeline of that distance is tested for leaks. When testing the pipeline for leaks, it is necessary to first seal the pipeline in the corresponding area, and then inject water into one end of the pipeline. During the water injection process, a water supply device needs to be connected to the end of the pipeline.

[0004] When connecting some metal pipes, the metal pipes usually come with flanges, and the connection device can be connected using the flange connection structure. With the rise of polymer materials, most existing pipes are made of polymer materials. These pipes are usually connected by socket or hot melt methods, so there are no flange assemblies for connection. Generally, clamps are used to connect the hoses to the pipes.

[0005] The most important problem to solve when using clamps to connect hoses to pipes is sealing. Since the clamps are two-piece, there are gaps at the connection points that can cause water leakage. Also, it is not convenient to install clamps in the confined space inside the manhole. Therefore, it is necessary to improve the existing design and create a tight-fitting structure to connect with the pipe, which is convenient for installation in the confined space inside the manhole, and also improves the sealing performance. Utility Model Content

[0006] The purpose of this utility model is to provide a quick water supply connector in order to solve the above-mentioned problems.

[0007] The technical solution adopted by this utility model is as follows: a quick water supply connector, including a sleeve and a hose, a hose is connected to one side of the sleeve, a bracket is inserted and movably installed inside the other side of the sleeve, a sealing strip A is tightly fitted to one side of the bracket, a sealing strip B is tightly fitted to the outer ring of the bracket, a support component is provided on one side of the sleeve to tighten the sleeve and the pipe, and an auxiliary component is provided on the outside of the sleeve to concentrically connect the pipe. The support components include: bracket, double-ended lead screw, support rod A, support rod B, and top block; The socket is located on one side of the hose and is equipped with a support rod A via a bracket. The support rod A is equipped with a support rod B via a double-ended screw. The other part of the support rod B is integrally provided with a top block. Auxiliary components include: slide rail, anti-disengagement mechanism, sliding sleeve, sliding column, linkage block, and gripper; The outer ring of the socket is embedded with a sliding groove, and the outer ring of the socket is provided with an anti-disengagement groove. The anti-disengagement groove is connected to a clamping claw by a tension spring. The outer side of the socket is rotatably connected to a sliding sleeve, and the inner ring of the sliding sleeve is provided with sliding columns and linkage blocks at intervals.

[0008] The number of the sliding groove, the anti-detachment groove, the sliding column, and the linkage block are all three, and they are all arranged in an equilateral triangle. The sliding groove and the sliding column correspond to each other and are slidably connected.

[0009] The gripper end is arc-shaped, and its surface has several protrusions. The gripper corresponds to the linkage block, which is inclined.

[0010] The sliding sleeve is provided with a handle on its outside.

[0011] The threads on the two sections of the double-ended lead screw are arranged in opposite directions, and the double-ended lead screw is threadedly connected to support rod A and support rod B.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, the linkage block uses an inclined surface to make the three grippers move synchronously towards the inside of the sleeve joint, so that the grippers contact the outer wall of the pipe, thereby achieving the purpose of the three grippers being at the same distance from the pipe, making the sleeve joint and the center of the pipe in a straight line, ensuring that the sealing strip A and the pipe opening are subjected to uniform force, and improving the sealing effect.

[0013] 2. In this utility model, by rotating the double-ended screw through the handle, the reverse threads can make the support rod A and support rod B move closer or further apart. When the support rod A and support rod B move further apart, the top block can be pressed tightly against the well, increasing the support strength. This design makes the device easier to install.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In this utility model: (Refer to...) Figure 1-5 A quick water supply connector includes a sleeve 1 and a hose 101. The hose 101 is connected to one side of the sleeve 1, and a bracket 5 is inserted and movably installed inside the other side of the sleeve 1. This configuration allows the bracket 5 to be replaced. A sealing strip A501 is tightly fitted to one side of the bracket 5, and a sealing strip B502 is tightly fitted to the outer ring of the bracket 5. The sealing strip B502 ensures the sealing between the bracket 5 and the sleeve 1. A support component is provided on one side of the sleeve 1 to tighten the sleeve 1 with the pipe. An auxiliary component is provided on the outside of the sleeve 1 to concentrically connect the pipe. The support assembly includes: bracket 102, double-ended lead screw 2, support rod A201, support rod B202, and top block 3; One side of the socket 1 is located outside the hose 101 and is equipped with a support rod A201 via a bracket 102. The support rod A201 is connected to a support rod B202 via a double-ended threaded rod 2. The other end of the support rod B202 is integrally equipped with a top block 3. The threads on the two ends of the double-ended threaded rod 2 are reversed, and the double-ended threaded rod 2 is threadedly connected to the support rods A201 and B202. When the socket 1 is aligned with the center of the pipe, the double-ended threaded rod 2 can be rotated by turning the handle. The reversed threads allow the support rods A201 and B202 to move closer or further apart. When the support rods A201 and B202 move further apart, the top block 3 can be pressed tightly against the shaft, increasing the support strength. This design makes the device easier to install. The auxiliary components include: slide groove 4, anti-disengagement groove 401, slide sleeve 6, slide column 601, linkage block 602, and gripper 7; The outer ring of the socket 1 is embedded with a sliding groove 4, and the outer ring of the socket 1 is provided with an anti-disengagement groove 401. The anti-disengagement groove 401 is connected to a clamp 7 by a tension spring. The outer side of the socket 1 is rotatably connected to a sliding sleeve 6. The inner ring of the sliding sleeve 6 is provided with a sliding column 601 and a linkage block 602 at intervals.

[0018] Furthermore, there are three of each of the following: the sliding groove 4, the anti-detachment groove 401, the sliding column 601, and the linkage block 602. They are all arranged in an equilateral triangle. The sliding groove 4 and the sliding column 601 correspond to each other and are slidably connected. By rotating the sliding sleeve 6 with the handle, the sliding column 601 can move inside the sliding groove 4, which in turn drives the linkage block 602 to act. The linkage block 602 uses the inclined surface to make the three grippers 7 move synchronously towards the inside of the sleeve joint 1, so that the grippers 7 contact the outer wall of the pipe. This achieves the purpose of the three grippers 7 being at the same distance from the pipe, so that the center of the sleeve joint 1 and the pipe are in a straight line. This ensures that the sealing strip A501 and the pipe opening are subjected to uniform force, thus improving the sealing effect.

[0019] Furthermore, the end of the gripper 7 is arc-shaped, and the surface is provided with several protrusions. The gripper 7 corresponds to the linkage block 602, which is set with an inclined surface. This setting makes the movement of the gripper 7 more linear when the linkage block 602 and the gripper 7 work together, and it can be continuously hovered, thus making it suitable for pipes of different diameters.

[0020] Furthermore, a handle is provided on the outside of the sliding sleeve 6, and a handle is also provided in the middle of the double-ended lead screw 2. By utilizing the lever principle generated by the handle, the sliding sleeve 6 and the double-ended lead screw 2 can be driven with less effort.

[0021] Working principle: First, the sleeve 1 is placed on the pipe. By rotating the handle, the sliding sleeve 6 moves the sliding column 601 inside the sliding groove 4, which in turn drives the linkage block 602. The linkage block 602, using its inclined surface, causes the three grippers 7 to move synchronously towards the inside of the sleeve 1, making the grippers 7 contact the outer wall of the pipe. This ensures that the distance between the three grippers 7 and the pipe is the same, aligning the sleeve 1 with the center of the pipe. Next, by rotating the handle, the double-ended screw 2, using the reverse thread, can... Support rods A201 and B202 can move closer or further apart. When support rods A201 and B202 move further apart, the top block 3 can be pressed tightly against the well, and the sealing strip A501 is also connected to the pipe. When the device is under force, the sliding sleeve 6 is rotated, and then the double-ended screw 2 is rotated to further increase the support strength, so that the sealing strip A501 is also tightly connected to the pipe. The sealing strip B502 ensures the sealing between the bracket 5 and the sleeve joint 1, which facilitates water supply to the pipe through the hose 101.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
