Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Embodiments of this utility model: such as Figures 1-7 As shown, an information room cable puller includes a traction rod 1 and a handle 2. The handle 2 is fixed to one end of the traction rod 1, and a connecting part 3 is installed at the other end of the traction rod 1. The connecting part 3 includes a first connector 301 and a second connector 302. A fixing plate 4 is fixed to one end of the first connector 301. The fixing plate 4 is an annular plate. The other end of the first connector 301 is connected to one end of the second connector 302. The other end of the second connector 302 is fixedly connected to the end of the traction rod 1 away from the handle 2. A through groove 6 is opened on the side wall of the first connector 301. An installation block 7 is installed in the through groove 6. An adjustment mechanism 8 is provided at both ends of the installation block 7. A pulley 5 is installed on each of the two adjustment mechanisms 8.

[0027] The traction rod 1 has a certain degree of rigidity and can be bent. The traction rod 1 can push the connecting part 3 to move inside the pipe. In use, first insert the fixing plate 4 into the pipe. With the pulley 5 sliding inside the pipe and the traction rod 1 pushing, the fixing plate 4 passes through the other opening of the pipe. Then, the wire is wrapped around the fixing plate 4, and the handle 2 is pulled. Under the traction of the traction rod 1, the wire can be pulled to achieve the purpose of threading. During the pulling process, the height of the pulley 5 can be adjusted by the adjustment mechanism 8, so as to avoid the situation where the position of the pulley 5 cannot be adjusted and it is easy to damage the pipe. At the same time, by setting the through groove 6 and the mounting block 7, the pulley 5 can be disassembled and replaced when it is worn.

[0028] Specifically, the adjustment mechanism 8 includes a rotating groove 801, a mounting bracket 802, a rotating rod 803, and an elastic component 804. The mounting block 7 has rotating grooves 801 at both ends. The mounting bracket 802 is movably installed within the rotating grooves 801. The mounting bracket 802 is a U-shaped support. The rotating rod 803 is rotatably mounted at the open end of the mounting bracket 802. A pulley 5 is fixedly sleeved on the rotating rod 803. An elastic component 804 is located at each of the four corners of the bottom of the mounting bracket 802. A bottom groove 805 is formed at the bottom of the inner cavity of the rotating groove 801, and the elastic component 804 is connected to the bottom of the inner cavity of the bottom groove 805.

[0029] When the traction process encounters a bend in the pipeline, the elastic component 804 deforms due to the compression between the inner wall of the pipeline and the pulley 5, thereby causing the pulley 5 to retract into the rotating groove 801, thus adjusting the height of the pulley 5.

[0030] In this embodiment, the elastic component 804 includes a sleeve rod 8041 connected to the bottom of the inner cavity of the bottom groove 805, a slide rod 8042 slidably sleeved with the sleeve rod 8041, a connecting plate 8043 connected to the bottom end of the slide rod 8042, and a spring 8044 sleeved inside the sleeve rod 8041. The two ends of the spring 8044 are fixedly connected to the bottom of the inner cavity of the sleeve rod 8041 and the bottom of the connecting plate 8043, respectively.

[0031] When pulley 5 is compressed and moves, it will drive slide bar 8042 to move. With the connection of connecting plate 8043, spring 8044 can be compressed, thereby adjusting the height of pulley 5. After leaving the bend position, under the action of the restoring force of spring 8044, pulley 5 can move upward to fit against the inner wall of the pipe. By rolling instead of friction, traction can be made smoother.

[0032] A stud 303 is fixedly connected to one end of the first connector 301 that connects to the second connector 302. A threaded groove 304 is provided at one end of the second connector 302, and the stud 303 is threadedly connected to the threaded groove 304. This structural design allows for the replacement of the traction rod 1 by disassembling the first connector 301 and the second connector 302 when wear occurs.

[0033] Furthermore, a bearing 806 is installed on the mounting bracket 802, and both ends of the rotating rod 803 are rotatably connected to the mounting bracket 802 through the bearing 806. A limiting sleeve 807 is fixedly sleeved on the surface of the rotating rod 803, and the limiting sleeve 807 is located on both sides of the pulley 5.

[0034] By setting the bearing 806, the rotation of the pulley 5 can be facilitated. By setting the limiting sleeve 807, the pulley 5 can be limited to prevent it from shaking.

[0035] Furthermore, two receiving grooves 701 are formed on the side wall of the first connector 301. The two receiving grooves 701 are located at both ends of the through groove 6, and are arranged opposite to each other and communicate with the through groove 6. Two receiving blocks 702 that mate with the receiving grooves 701 are fixed on the mounting block 7. One end of the first connector 301 is threaded with a screw 9, and the first connector 301 is detachably connected to the mounting block 7 through the screw 9.

[0036] By setting the receiving groove 701 and the receiving block 702, the mounting block 7 has a stress-bearing position during installation, and by setting the screw 9, the mounting block 7 can be easily disassembled and assembled.

[0037] The working principle of this utility model is as follows: When in use, first insert the fixing plate 4 into the pipe, slide the pulley 5 in the pipe and push the traction rod 1 until the fixing plate 4 passes through the other opening of the pipe. Then, wrap the wire around the fixing plate 4. By pulling the handle 2, the wire can be pulled under the traction of the traction rod 1, thereby achieving the purpose of threading the wire.

[0038] When the connecting part 3 encounters a corner during its movement, the pulley 5 protrudes from the surface of the connecting part 3, thus the corner will squeeze the pulley 5. When the pulley 5 is squeezed, the slide rod 8042 slides along the sleeve rod 8041, the connecting plate 8043 will compress the spring 8044, and the pulley 5 will move into the rotating groove 801, thereby preventing the pulley 5 from damaging the inner wall of the pipe at the corner. When it passes the corner, under the elastic force of the spring 8044, the pulley 5 moves towards the outside of the rotating groove 801 and contacts the inner wall of the pipe.

[0039] By setting the through groove 6 and the mounting block 7, the pulley 5 can be disassembled and replaced when it wears out.

[0040] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
