[0025] Reference Figures 1-5 The utility model provides a telescopic positioning pin for an automobile assembly line, comprising a cylinder 1, a moving cylinder 5 is slidably connected inside the cylinder 1, a power component 3 is arranged inside the cylinder 1, the power component 3 is used to drive the moving cylinder 5 to move, a blocking component 6 is arranged inside the moving cylinder 5, and the lower end of the moving cylinder 5 is in a cone shape.

[0026] Specifically, when assembling the automobile chassis, it is necessary to first insert the moving cylinder 5 and the cylinder 1 into the positioning hole. Since the lower end of the moving cylinder 5 is in a conical shape, it is convenient for the moving cylinder 5 to enter the positioning hole. After the moving cylinder 5 and the cylinder 1 enter the positioning hole, the length of the moving cylinder 5 can be changed with the cooperation of the power component 3, so as to facilitate the device to penetrate positioning holes of different depths, so that the positioning pin can be stably inserted into the positioning hole. At the same time, with the cooperation of the blocking component 6, after the positioning pin passes through the positioning hole, the blocking component 6 can effectively place the positioning pin out of the positioning hole, thereby achieving the purpose of stable positioning.

[0027] The power assembly 3 includes a threaded rod 301 and a handle 302. The threaded rod 301 is rotatably connected inside the cylinder 1, and the handle 302 is fixedly connected to the upper end of the threaded rod 301. The threaded rod 301 and the moving cylinder 5 are threadedly connected. When working, by rotating the handle 302, the threaded rod 301 can be driven to rotate, and then the moving cylinder 5 can be driven to move inside the cylinder 1, so that it is convenient to change the extended length of the moving cylinder 5.

[0028] A sliding hole 7 is provided on the circumferential surface of the cylinder 1, and a slider 8 is slidably connected inside the sliding hole 7. The slider 8 is fixedly connected to the moving cylinder 5. When working, the movement of the moving cylinder 5 can be limited by setting the sliding hole 7 and the slider 8, so that the moving cylinder 5 can move stably.

[0029] The blocking component 6 includes a support frame 601, a moving rod 602, a spring 603, a moving disk 604, a connecting block 605, a transmission rod 606 and a blocking rod 607. A support frame 601 is fixedly connected inside the moving cylinder 5. A moving rod 602 is slidably connected inside the support frame 601. A moving disk 604 is fixedly connected to the lower end of the moving rod 602. The moving disk 604 is slidably connected with the moving cylinder 5. A connecting block 605 is fixedly connected to the upper end of the moving disk 604. A transmission rod 606 is rotatably connected inside the connecting block 605. One end of the transmission rod 606 away from the connecting block 605 is rotatably connected to a blocking rod 607. The blocking rod 607 is slidably connected with the moving cylinder 5. A spring 603 is arranged on the circumferential surface of the moving rod 602. One end of the spring 603 is fixedly connected to the support frame 601, and the other end of the spring 603 is fixedly connected to the moving disk 604. During operation, when the moving cylinder 5 is received into the cylinder 1, at this time, the threaded rod 301 presses the moving rod 602 to slide inside the support frame 601, and then with the cooperation of the moving disk 604, the spring 603 can be stretched, so that with the cooperation of the transmission rod 606, the blocking rod 607 can be driven to contract into the moving cylinder 5. In this way, when the positioning pin is inserted again, it is convenient to use the positioning pin. When the moving cylinder 5 extends outwards, at this time, the threaded rod 301 no longer presses the moving rod 602, and then under the action of the compressed spring 603, the moving disk 604 can be driven to move upwards, thereby driving the blocking rod 607 to extend outwards. In this way, under the action of the blocking rod 607, a blocking effect can be achieved, effectively preventing the device from disengaging from the positioning hole.

[0030] A retaining ring 2 is fixedly connected to the circumferential surface of the cylinder 1. The retaining ring 2 is located at the upper end of the cylinder 1. During operation, by providing the retaining ring 2, and then with the cooperation of the blocking rod 607, an up-and-down blocking effect can be achieved, effectively preventing the device from disengaging from the positioning hole.

[0031] A plug rod 4 is slidably connected inside the threaded rod 301. The upper end of the plug rod 4 penetrates through the handle 302, and the lower end of the plug rod 4 penetrates through the threaded rod 301. During operation, when it is necessary to remove the positioning pin, the moving rod 602 is pushed by the plug rod 4, and at this time, the blocking rod 607 can be driven to contract into the moving cylinder 5, so as to facilitate the removal of the positioning pin from the positioning hole.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
