Description

Technical Field

[0001] The utility model relates to the technical field of cold shrink tubes, in particular to a drawing and recovery device for a cable cold shrink tube retaining frame. Background Art

[0002] Cold shrink tubing is often used to seal exposed cable connectors. Figure 1 The figure shows a cold shrink tube 4 and a corresponding retaining frame 41 in the prior art. The cold shrink tube 4 is made of elastic material, and the retaining frame 41 is formed by spirally winding a wire into a tubular structure. The diameter of the cold shrink tube 4 is expanded by an expansion device, and then the retaining frame 41 is inserted into the inside of the cold shrink tube 4 to support the cold shrink tube 4 and prevent the cold shrink tube 4 from shrinking. When in use, the cable passes through the retaining frame 41, and then one end of the retaining frame 41 is pulled to pull the retaining frame 41 out of the cold shrink tube 4. When the retaining frame 41 is pulled out, the cold shrink tube 4 automatically shrinks to cover the outside of the cable to play a role in waterproofing and sealing. Since the retaining frame 41 is a spiral tubular structure, when pulling out the retaining frame 41, it is necessary to wind the retaining frame out in a direction opposite to the spiral direction of the retaining frame 41, that is, during the specific operation, both hands need to be exchanged on both sides of the cable to perform the pulling operation, and the pulled-out retaining frame 41 is spirally extended and easily wrapped around the cable line, and the retaining frame 41 needs to be wound out of the cable a second time. The aforementioned process of withdrawing and removing the retainer 41 is cumbersome, time-consuming, and labor-intensive, making it difficult to meet the demand for withdrawing and removing the retainer 41. This disadvantage is particularly pronounced during on-site construction operations involving long cold shrink tubing 4. Furthermore, the retainer 41 is made of plastic and still has recycling value. However, during on-site construction, the withdrawn retainers 41 are chaotically stacked together, making it difficult to effectively organize and recycle them, hindering subsequent recycling and processing of the retainers 41.

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0030] like Figure 1-8 The figure shows a cable cold shrink tube holder extraction and recovery device described in this embodiment, which is used to extract and recover the holder 41 inside the cold shrink tube 4. The extraction and recovery device includes a first main body 1, a second main body 2, and an insert plate 3. The first main body 1 and the second main body 2 are both made of plastic. The first main body 1 has a thickness extending along the first direction. A V-shaped groove 11 and a holder insertion channel 13 are processed on the first main body 1. The V-shaped groove 11 passes through the first main body 1 along the first direction. One end of the V-shaped groove 11 forms an open end on the outer surface of the first main body 1. The cable 42 can be placed in the V-shaped groove 11 and is received by the V-shaped groove 11. The holder insertion channel 13 is arranged on one side of the V-shaped groove 11 and passes through the first main body 1 along the first direction. The holder insertion channel 13 is adapted to the size of the wire forming the holder 41, and one end of the wire forming the holder 41 can be inserted into the V-shaped groove 11. When one end of the retainer 41 is pulled, the wire can move along the first direction in the retainer insertion channel 13 .

[0031] Specifically, the cross-section of the retainer insertion channel 13 is L-shaped. The first end of the L-shaped structure has an inlet and outlet formed on the first outer arcuate surface 12, and the second end is closed. The wire forming the retainer 41 can enter and exit the interior of the retainer insertion channel 13 through the inlet and outlet of the L-shaped structure.

[0032] The aforementioned second body 2 is arranged above the V-shaped groove 11, and has a combined state of being plugged in and matched with the first body 1 along the first direction. Specifically, a first slot 15 extending along the first direction is processed on both side surfaces of the V-shaped groove 11. One end of the first slot 15 is open, and the other end is closed. A plug-in protrusion is formed on the second body 2 corresponding to the first slot 15. The second body 2 is plugged in and matched with the first slot 15 along the first direction through the plug-in protrusion, and can be limited by the closed end of the first slot 15. In this combined state, a accommodating space is formed between the second body 2 and the V-shaped groove 11. The aforementioned plug-in board 3 is installed in the accommodating space and is plugged in and matched with the second body 2 along the first direction. When the plug-in board 3 is plugged into the second body 2, a cable insertion space is formed between the plug-in board 3 and the V-shaped groove 11. The cable 42 is inserted into the cable insertion space and is restricted from moving in the radial direction. With the above-described structural design, when the cable 42 is inserted and restrained in the cable insertion space, the first body 1 and the second body 2 can be pushed to rotate as a whole around the cable 42, and the first body 1 and the second body 2 can be pushed to move as a whole on the cable 42 along the length direction of the cable 42. Specifically, when the first body 1 and the second body 2 rotate as a whole around the cable 42, the wire inserted in the retainer insertion channel 13 can rotate along with the cable 42.

[0033] In this embodiment, a rubber layer 31 or a sponge layer is installed on the bottom surface of the plugboard 3 facing the V-shaped groove 11. When the cable 42 is inserted into the cable insertion space, the rubber layer 31 or the sponge layer contacts the outer sheath of the cable 42.

[0034] The second body 2 is formed with two sets of extension plates 23 extending toward the V-groove 11. These two sets of extension plates 23 are spaced apart with a plurality of second slots 24 spaced apart in a direction toward or away from the V-groove 11. The second slots 24 are open at both ends, and the plug-in plate 3 engages with the second slots 24 along a first direction. By inserting the plug-in plate 3 into the second slots 24 at different positions, the relative distance between the plug-in plate 3 and the V-groove 11 can be adjusted, thereby meeting the insertion and limiting requirements of cables 42 with different outer diameters.

[0035] In this embodiment, the first body 1 is formed with a first outer arcuate surface 12 around a central axis extending in the first direction. The second body 2 is formed with a second outer arcuate surface 21 around a central axis extending in the first direction. When the first and second bodies 1 and 2 are assembled, the first and second outer arcuate surfaces 12 and 21 combine to form an annular winding surface. In this embodiment, the winding surface is a circumferential surface. The wire forming the retainer 41 can be wound around this winding surface.

[0036] In this embodiment, a first stop plate 14 is arranged on the first side of the first outer arc surface on the aforementioned first main body 1. A second stop plate is arranged on the second side of the second outer arc surface on the second main body 2. A limiting distance is formed between the first stop plate 14 and the second stop plate, and the above-mentioned first side and second side are two opposite sides located in the first direction. The first stop plate 14 and the second stop plate are limited to limit the movement of the wire wound on the winding surface in the first direction. Several recessed structures 5 are processed on the outer edges of the first stop plate 14 and the second stop plate. The recessed structure 5 plays an anti-slip role. When holding the first main body 1 and the second main body 2, the recessed structure 5 can stably and smoothly push the first main body 1 and the second main body 2 to rotate around the cable 42.

[0037] During specific use, the first body 1 and the second body 2 are placed on both sides of the cable 42, and then the first body 1 and the second body 2 are plugged into each other so that the first body 1 and the second body 2 are sleeved on the cable 42. Then the plug board 3 is inserted into the second slot 24 at the corresponding position so that the cable 42 is inserted and limited in the cable insertion space between the plug board 3 and the V-shaped groove 11. One end of the retaining frame 41 is inserted into the retaining frame insertion channel 13. One hand pushes the first body 1 and the second body 2 to rotate unidirectionally around the cable 42. Each time it rotates to a predetermined position, the other hand pulls the retaining frame 41 outward to pull the retaining frame 41 out of the cold shrink tube 4. After pulling and pulling, the first body 1 and the second body 2 are disassembled to separate from the cable 42. In the above method, there is no need to exchange both hands for pulling and pulling operations, and during the pulling process, the retaining frame 41 is away from the cable 42 and is difficult to be wrapped around the cable 42, which simplifies the pulling steps of the retaining frame 41, saves time and effort, and can adapt to the pulling and pulling operations of the retaining frame 41 with a longer length, and is highly practical.

[0038] After the above-mentioned retaining frame 41 is pulled out, the first main body 1 and the second main body 2 are plugged into each other and combined, and the wire material that is pulled out to form the retaining frame 41 is rolled onto the winding surface, so that the retaining frame 41 is recycled into a roll. When the first main body 1 and the second main body 2 are separated from each other again, the rolled retaining frame 41 can be separated from the winding surface and recycled. In the above manner, the retaining frame 41 can be recycled by rolling it up, so that the retaining frame 41 is recycled in a regular and orderly manner, effectively meeting the requirements of the pulling and recycling operation of the retaining frame 41.

[0039] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
