Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a push-pull self-locking double-headed connector structure. Background Technology

[0002] Pipe connectors are used to quickly connect two pipes. Compared with flanges and welding repair methods, pipe connectors not only save the space, time and money required by flanges and welding, but also fully guarantee their quality. They are gradually replacing some traditional pipe technologies and are widely used in various industries. Pipe connection refers to connecting pre-fabricated pipe sections into a complete system according to the design drawings. Connector refers to the process of using fasteners to connect two separate profiles or parts into a complex part or component.

[0003] In the use of existing connectors, auxiliary tools such as bolts are often used to ensure the stability of the connection. This not only greatly increases the complexity of the work, but also causes great inconvenience to the subsequent disassembly work. Therefore, a push-pull self-locking double-headed connector structure is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a push-pull self-locking double-headed connector structure, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a push-pull self-locking double-headed connector structure, including a first pipe, a second pipe at one end of the first pipe, a first connecting pipe and a second connecting pipe respectively fixedly connected to corresponding ends of the first pipe and the second pipe, an annular groove at one end of the first connecting pipe, a slidably connected end of the second connecting pipe to the annular groove, a first rectangular frame fixedly connected to one side of the outer wall of the first connecting pipe, a hollow frame fixedly connected to the top surface of the outer wall of the first rectangular frame, the hollow frame communicating with the interior of the first rectangular frame, a locking block slidably connected inside the hollow frame, the locking block being triangular in shape, a first slider fixedly connected to the outer wall of the second connecting pipe near the first rectangular frame, the first slider slidably connected to the first rectangular frame, a locking groove at one side of the first slider, the locking block engaging with the locking groove, a first spring fixedly connected inside the hollow frame, the other end of the first spring fixedly connected to one side of the first slider.

[0006] Preferably, one end of both the first connecting pipe and the second connecting pipe is fixedly connected with a sealing ring.

[0007] The technical effect achieved by adopting the above solution is that, by using this solution, when the second connecting pipe extends into the first connecting pipe, the sealing ring can be used to increase the sealing effect between the two, reduce the risk of water leakage, and make it more reliable.

[0008] Preferably, in any of the above solutions, a second slider is fixedly connected to the end of the outer wall of the second pipe away from the first slider, and a second rectangular frame is fixedly connected to the outer wall of the first connecting pipe near the second slider, and the second slider is slidably connected to the second rectangular frame.

[0009] The technical effect achieved by adopting the above solution is that when the second slider is slidably connected to the second rectangular frame, the tightness and stability of the connection between the first pipe and the second pipe can be increased.

[0010] Preferably, in any of the above solutions, two second springs are fixedly connected to the inner wall of the second rectangular frame, and one side of the second slider is in contact with the two second springs.

[0011] The technical effect achieved by adopting the above solution is that when the card block and slot are unlocked, the second spring will push the first pipe and the second pipe to separate, making the separation and disassembly of the first pipe and the second pipe more convenient.

[0012] Preferably, in any of the above embodiments, a pull rod is provided inside the hollow frame, one end of the pull rod is fixedly connected to one side of the locking block, and the other end of the pull rod extends out of the hollow frame and is fixedly connected to a pinch plate.

[0013] The technical effect achieved by the above solution is that by using this solution, the pinch plate can be pulled to move the lever, and the lever can move the locking block upward away from the slot, so that the locking block is released from the slot and the locking effect of the first and second pipes can be released.

[0014] Preferably, in any of the above solutions, the ends of the first slider and the second slider away from the second pipe are both provided with chamfers.

[0015] The technical effect achieved by adopting the above solution is that by using this solution, the first slider and the second slider can be smoothly inserted into the interior of the first rectangular frame and the second rectangular frame when the first pipe and the second pipe are connected, which further reduces the difficulty of connecting the first pipe and the second pipe and makes it more convenient.

[0016] This utility model has the following advantages: 1. This push-pull self-locking double-ended connector structure allows the second connecting tube to extend into the annular groove. When the second connecting tube extends into the first connecting tube, the sealing ring can be used to increase the sealing effect between the two, reduce the risk of water leakage, and make it more reliable. At the same time, when the first and second sliders are connected, they enter the first and second rectangular frames respectively, further limiting the first and second pipes and preventing them from rotating freely, making the connection more stable.

[0017] 2. This push-pull self-locking double-headed connector structure, when the first slider is inserted into the first rectangular frame, will first squeeze the locking block to move upward, and then the locking block will be squeezed by the first spring and enter the locking groove, thus locking the first pipe and the second pipe. At this time, the first pipe and the second pipe cannot be separated or rotated at will, making the operation more convenient, requiring less manpower, and the locking effect is also guaranteed.

[0018] 3. This push-pull self-locking double-headed connector structure allows for the separation of the first and second pipes. Pulling the pinch plate moves the pull rod, which in turn moves the locking block upward away from the slot, thus releasing the locking effect of the first and second pipes and further ensuring the ease of disassembly.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0022] like Figures 1 to 6 As shown, a push-pull self-locking double-ended connector structure includes a first pipe 1, a second pipe 3 at one end of the first pipe 1, a first connecting pipe 19 and a second connecting pipe 7 respectively fixedly connected to the corresponding ends of the first pipe 1 and the second pipe 3, an annular groove 18 is formed at one end of the first connecting pipe 19, and one end of the second connecting pipe 7 is slidably connected to the annular groove 18, a first rectangular frame 14 is fixedly connected to one side of the outer wall of the first connecting pipe 19, a hollow frame 15 is fixedly connected to the top surface of the outer wall of the first rectangular frame 14, the hollow frame 15 is connected to the interior of the first rectangular frame 14, a locking block 9 is slidably connected inside the hollow frame 15, the locking block 9 is triangular, a first slider 11 is fixedly connected to the outer wall of the second connecting pipe 7 near the position of the first rectangular frame 14, the first slider 11 is slidably connected to the first rectangular frame 14, a locking groove 10 is formed on one side of the first slider 11, the locking block 9 is engaged with the locking groove 10, a first spring 12 is fixedly connected inside the hollow frame 15, and the other end of the first spring 12 is fixedly connected to one side of the first slider 11.

[0023] As an optional technical solution of this utility model, a sealing ring 8 is fixedly connected to one end of the first connecting pipe 19 and the second connecting pipe 7. By using this solution, when the second connecting pipe 7 extends into the first connecting pipe 19, the sealing ring 8 can be used to increase the sealing between the two, reduce the risk of water leakage, and make it more reliable.

[0024] As an optional technical solution of this utility model, a second slider 5 is fixedly connected to the end of the outer wall of the second pipe 3 away from the first slider 11, and a second rectangular frame 6 is fixedly connected to the outer wall of the first connecting pipe 19 near the second slider 5. The second slider 5 and the second rectangular frame 6 are slidably connected. By using this solution, when the second slider 6 and the second rectangular frame 6 are slidably connected, the tightness and stability of the connection between the first pipe 1 and the second pipe 3 can be increased.

[0025] As an optional technical solution of this utility model, two second springs 16 are fixedly connected to the inner wall of the second rectangular frame 6. One side of the second slider 5 is in contact with the two second springs 16. By using this solution, when the locking block 9 and the locking slot 10 are unlocked, the second springs 16 will push the first pipe 1 and the second pipe 3 to separate, making the separation and disassembly of the first pipe 1 and the second pipe 3 more convenient.

[0026] As an optional technical solution of this utility model, a pull rod 13 is provided inside the hollow frame 15. One end of the pull rod 13 is fixedly connected to one side of the locking block 9, and the other end of the pull rod 13 extends out of the hollow frame 15 and is fixedly connected to the pinch plate 2. By using this solution, the pinch plate 2 can be pulled to move the pull rod 13. The pull rod 13 moves the locking block 9 upward away from the slot 10, so that the locking block 9 is disengaged from the slot 10 and the locking effect of the first pipe 1 and the second pipe 3 can be released.

[0027] As an optional technical solution of this utility model, the ends of the first slider 11 and the second slider 5 away from the second pipe 3 are both provided with chamfers. By using this solution, the first slider 11 and the second slider 5 can be smoothly inserted into the interior of the first rectangular frame 14 and the second rectangular frame 6 when the first pipe 1 and the second pipe 3 are connected, which further reduces the difficulty of connecting the first pipe 1 and the second pipe 3 and makes it more convenient.

[0028] This push-pull self-locking double-ended connector structure requires the following steps for use: 1) Insert the second connecting pipe 7 into the interior of the annular groove 18; 2) When the first slider 11 and the second slider 5 are connected to the first pipe 1 and the second pipe 3, they respectively enter the interior of the first rectangular frame 14 and the second rectangular frame 6; 3) When the locking block 9 is pressed by the first spring 12, it enters the slot 10, thus locking the first pipe 1 and the second pipe 3. 4) Pull rod 13 moves the locking block 9 upward away from the slot 10, causing the locking block 9 to disengage from the slot 10 and release the locking effect of the first pipe 1 and the second pipe 3.

[0029] In summary, when the user uses the device, the second connecting pipe 7 is inserted into the annular groove 18. After the second connecting pipe 7 is inserted into the first connecting pipe 19, the sealing ring 8 can be used to increase the sealing between the two, reducing the risk of leakage and making it more reliable. At the same time, when the first pipe 1 and the second sliding block 5 are connected, they enter the first rectangular frame 14 and the second rectangular frame 6 respectively, further limiting the first pipe 1 and the second pipe 3 and preventing them from rotating freely, making the connection more stable. When the first sliding block 11 is inserted into the first rectangular frame 14, it will first squeeze the locking block 9 upward. The movement causes the locking block 9 to be squeezed by the first spring 12 and enter the slot 10, thus locking the first pipe 1 and the second pipe 3. At this time, the first pipe 1 and the second pipe 3 cannot be separated or rotated at will, making the operation more convenient and requiring less manpower. The locking effect is also guaranteed. Finally, when it is necessary to separate the first pipe 1 and the second pipe 3, pull the pinch plate 2 to move the pull rod 13. The pull rod 13 moves the locking block 9 upward away from the slot 10, so that the locking block 9 is released from the slot 10 and the locking effect of the first pipe 1 and the second pipe 3 can be released, further ensuring the convenience of disassembly.
