Description

Technical Field

[0001] This utility model relates to the field of wall pipe connection, and in particular to a quick connector device for winding structural wall pipes. Background Technology

[0002] Spiral wound structured wall pipe, as a new type of pipe material, has been widely used in many fields such as municipal drainage, sewage engineering, farmland irrigation, and industrial wastewater discharge due to its unique structure and excellent performance. It is usually made of high-density polyethylene and other polymer materials through a winding molding process, and has significant advantages such as light weight, corrosion resistance, impact resistance, good water flow performance, and long service life.

[0003] Existing spiral wound pipe joints typically use clamp-type joints made of metal or high-strength plastic. Multiple bolts are used to clamp the two pipe ends together, and waterproofing is achieved by relying on built-in sealing rings. However, in actual operation, after the pipe is inserted into the clamp, multiple bolts need to be tightened one by one with tools to achieve fixation. The operation process is cumbersome and time-consuming, making it difficult to achieve rapid pipe connection and seriously affecting the efficiency of connection.

[0004] Therefore, it is necessary to design a quick coupling device for winding structural wall pipes that can be quickly unlocked or locked by pressing the sliding frame for rapid docking of the pipe wall, which is simple to operate, saves time, and improves docking efficiency. Utility Model Content

[0005] To overcome the shortcomings of the current practice where multiple bolts need to be tightened one by one after the wall pipe is inserted into the clamp to achieve fixation, which is cumbersome, time-consuming, and makes it difficult to achieve rapid connection of the wall pipe, thus seriously affecting the efficiency of connection, this utility model provides a quick connector device for winding structure wall pipes that can quickly unlock or lock the sliding frame for rapid connection of the wall pipe. The device is simple to operate, saves time, and improves the efficiency of connection.

[0006] The technical solution is as follows: A quick connector device for winding structural wall pipe includes a connecting pipe, a connecting block, a sliding frame, a clamping block, a first spring, a limiting frame, and a locking component. Connecting blocks are connected to the upper sides of both the left and right sides of the connecting pipe. Sliding frames are slidably connected to the connecting blocks. Multiple clamping blocks are slidably connected to the inner sides of both the left and right sides of the connecting pipe. Two limiting frames are slidably connected to the connecting pipe. The limiting frames are in contact with the clamping blocks on the same side. A first spring is connected between the limiting frames and the connecting pipe. The connecting blocks are equipped with locking components for locking and unlocking the position of the limiting frames.

[0007] In one embodiment, the connecting pipe has two sliding grooves, one on the left and one on the right, on both the upper and lower parts.

[0008] In one embodiment, the clamps are all arc-shaped.

[0009] In one embodiment, the clamps are evenly distributed along the connecting pipe.

[0010] In one embodiment, the locking assembly includes a top block, a lifting block, a support rod, a connecting rod, a connecting plate, a second spring, and a slider. The lower part of each connecting block is slidably connected to a top block, and each top block is in contact with an adjacent limiting frame. Each top block is connected to a lifting block on its upper side, and each lifting block is slidably connected to a connecting block on the same side. The lower part of each sliding frame is rotatably connected to a connecting rod, and each connecting rod is connected to a support rod. Each connecting block is connected to a connecting plate on its upper inner side, and each sliding frame is slidably connected to a connecting plate on the same side. A second spring is connected between each sliding frame and the connecting plate on the same side. The lower part of each support rod is connected to a slider, and each slider is slidably connected to a lifting block on the same side.

[0011] In one embodiment, the lower side of the top block is a slope.

[0012] The beneficial effects of this utility model are as follows: This utility model unlocks the wall tube by pressing the sliding frame to move the top block, which then presses the limiting frame to move and disengage from the clamping block. The wall tube is then pushed into the connecting tube for docking. Pressing the sliding frame again causes the top block and the limiting frame to move and reset, and pushes the clamping block to move and reset, allowing the wall tube to contact and lock. This allows for quick unlocking or locking of the wall tube by pressing the sliding frame, making the operation simple, saving time, and improving docking efficiency. Attached Figure Description

Detailed Implementation

[0018] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0019] A quick coupling device for winding structural wall pipes, such as Figures 1-4 As shown, it includes a connecting pipe 1, a connecting block 2, a sliding frame 3, a clamping block 4, a first spring 5, a limiting frame 6, and a locking assembly. The connecting pipe 1 is connected to the upper side of both the left and right sides with connecting blocks 2. The connecting blocks 2 are slidably connected to the sliding frames 3. The connecting pipe 1 is connected to the inner side of both the left and right sides with four clamping blocks 4. The clamping blocks 4 are all arc-shaped to facilitate fitting the shape of the pipe wall. The clamping blocks 4 are evenly distributed along the connecting pipe 1. The connecting pipe 1 is slidably connected to the left and right limiting frames 6. The limiting frames 6 are in contact with the clamping blocks 4 on the same side. The connecting pipe 1 has two sliding grooves on the upper and lower parts to facilitate the movement of the limiting frames 6. The limiting frames 6 are connected to the connecting pipe 1 with the first spring 5. The connecting blocks 2 are equipped with locking assemblies for locking and unlocking the position of the limiting frames 6.

[0020] like Figure 3 and Figure 4 As shown, the locking assembly includes a top block 7, a lifting block 8, a support rod 9, a connecting rod 10, a connecting plate 11, a second spring 12, and a slider 13. The lower part of each connecting block 2 is slidably connected to the top block 7, and each top block 7 is in contact with the adjacent limiting frame 6. The lower side of each top block 7 is inclined to facilitate compression. The upper side of each top block 7 is connected to the lifting block 8, and each lifting block 8 is slidably connected to the connecting block 2 on the same side. The lower part of each sliding frame 3 is rotatably connected to the connecting rod 10, and each connecting rod 10 is connected to the support rod 9. The upper inner side of each connecting block 2 is connected to the connecting plate 11 on the same side, and each sliding frame 3 is slidably connected to the connecting plate 11 on the same side. A second spring 12 is connected between each sliding frame 3 and the connecting plate 11 on the same side. The lower part of each support rod 9 is connected to the slider 13, and each slider 13 is slidably connected to the lifting block 8 on the same side.

[0021] When rapid docking of the wound structure wall tube is required, this device can be used. By pressing the sliding frame 3 downwards along the connecting block 2 and connecting plate 11, the second spring 12 is compressed, which in turn drives the support rod 9 and connecting rod 10 downwards, and pushes the top block 7 and lifting block 8 downwards. The compression limit frame 6 moves inwards along the slide groove and disengages from the clamping block 4, the first spring 5 is compressed, the clamping blocks 4 are all arc-shaped, and the lower side of the top block 7 is all inclined. Then, the sliding frame 3 is released, the second spring 12 rebounds, the sliding frame 3 moves upwards to reset, and drives the top block 7 and lifting block 8 to move upwards to reset, so that the slider 13 moves to the upper part of the groove on the lifting block 8, which in turn drives the support rod 9 and connecting rod 10 to rotate and return to their original positions. Then, the wound structure wall tube is brought into contact with the connecting tube 1, and the wall tube is pushed to move into contact with the clamping block 4, and the clamping block 4 is compressed to move towards the side of the connecting tube 1. Continue pushing the wall tubes to make contact and dock them. Then press the sliding frame 3 down again, compressing the second spring 12, which drives the support rod 9 and connecting rod 10 to move down, causing the slider 13 to move to the lower part of the groove on the lifting block 8. This causes the support rod 9 and connecting rod 10 to rotate and return to their original positions. Then release the sliding frame 3, the second spring 12 rebounds, and the sliding frame 3 moves up to reset, driving the support rod 9 and connecting rod 10 to move up. This pulls the top block 7 and lifting block 8 to move up, the first spring 5 rebounds, the limit frame 6 moves to reset and contacts the clamping block 4, and compresses the clamping block 4 to reset and contact the wall tube for fixation. The clamping blocks 4 are evenly distributed along the connecting tube 1, so that pressing the sliding frame 3 can quickly unlock or lock the wall tubes for quick docking. The operation is simple, saves time, and improves docking efficiency. Then repeat the above operation to dock other wall tubes.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
