Description

Technical Field

[0001] This utility model relates to the field of urban rail transit signal system construction technology, specifically to a horizontal and vertical cable stripping tool. Background Technology

[0002] When terminating cables in a signal control room, the outer sheath needs to be stripped to expose the internal conductors for wiring. This often involves both horizontal and vertical stripping. Existing cable stripping tools cannot perform both horizontal and vertical cutting with a single tool, requiring two different tools. Furthermore, they struggle to handle cables of different diameters, cannot precisely adjust the stripping depth, and are prone to damaging the internal conductors. This results in low stripping efficiency and poor stripping quality. Therefore, a more convenient integrated horizontal and vertical stripping device is needed to improve cable stripping efficiency and reduce stripping time. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model; in the description of this utility model, "a plurality of" or "several" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] Please see Figures 1 to 6 As shown, this utility model is a transverse and longitudinal cable stripping tool, including a lifting workpiece 1, an outer rod 2 fixedly connected to one end of the lifting workpiece 1, a threaded rod 21 threadedly connected to the inside of the outer rod 2, a connecting workpiece 23 rotatably connected to one end of the threaded rod 21 extending into the lifting workpiece 1, a blade support 24 fixedly connected to one end of the connecting workpiece 23 away from the threaded rod 21, a blade 25 disposed inside the blade support 24, the blade 25 having an arc-shaped or straight cutting edge, a cutter shaft 26 fixedly connected inside the blade 25, both ends of the cutter shaft 26 penetrating the side wall of the blade support 24 and extending to its outer side, and both ends of the cutter shaft 26 extending to the outer side of the blade support 24 being threadedly connected to a fixing nut 27.

[0032] During operation, rotating the threaded rod 21 drives the blade 25 to move within the workpiece 1. The thread allows for more precise movement of the blade 25. The blade shaft 26 enables the blade 25 to rotate within the blade support 24, thus achieving the cutting function.

[0033] In this embodiment, specifically, a first fixing groove is provided on the inner wall of the workpiece 1, and a second fixing groove is provided on the upper surface and side wall of the workpiece 23. A fixing member 4 is provided above the workpiece 1, and a telescopic rod 41 is fixedly connected to the top of the fixing member 4. The end of the telescopic rod 41 away from the fixing member 4 is inserted into the first fixing groove, and the bottom of the fixing member 4 is inserted into the second fixing groove.

[0034] During operation, when the blade 25 moves to the appropriate position under the drive of the threaded rod 21, the rotating connecting workpiece 23 is rotated. The connecting workpiece 23 has a cylindrical structure, thereby controlling whether the blade 25 is in a horizontal or vertical state. Then, the end of the telescopic rod 41 is first inserted into the first fixing groove to fix the telescopic rod 41. Then, the bottom of the fixing part 4 is inserted into the second fixing groove. Thus, regardless of whether the blade 25 is in a horizontal or vertical state, the fixing part 4 and the telescopic rod 41 can fix the blade 25, preventing the blade 25 from changing its state during operation.

[0035] In addition, the shape of the connecting workpiece 23 can be set to cylindrical. At this time, a clamp can be installed at the bottom of the fixing part 4. In special cases, if it is necessary to cut the cable 3 at an angle, the blade 25 can be tilted by rotating the connecting workpiece 23, and then the connecting workpiece 23 can be fixed by the clamp at the bottom of the fixing part 4.

[0036] In this embodiment, specifically, a bottom support base 101 is fixedly connected to the bottom of the workpiece 1, and a handle 102 is fixedly connected to the other end of the workpiece 1.

[0037] In this embodiment, specifically, the end of the threaded rod 21 away from the outer rod 2 is fixedly connected to a rubber head 22.

[0038] In this embodiment, specifically, a cable 3 is provided inside the workpiece 1.

[0039] In this embodiment, specifically, the inner wall of the workpiece 1 is provided with a hollow groove 5 and a pair of outer grooves 51. The pair of outer grooves 51 are distributed on both sides of the hollow groove 5. The inner wall of the outer groove 51 is rotatably connected to a second roller 53, and the inner wall of the hollow groove 5 is provided with a first roller 52.

[0040] In this embodiment, specifically, a limiting groove 64 is formed inside the empty groove 5, a first roller 52 is set in the limiting groove 64, a roller connecting shaft 6 is rotatably connected inside the first roller 52, the roller connecting shaft 6 is slidably connected in the limiting groove 64, a damping device 61 is provided inside the empty groove 5, a sliding groove 63 is formed at the bottom of the empty groove 5, one end of the damping device 61 is rotatably connected to the roller connecting shaft 6, the other end of the damping device 61 is slidably connected in the sliding groove 63, and a limiting nut 62 is threadedly connected to one end of the damping device 61 that extends to the outside of the workpiece 1.

[0041] When placing cable 3, cable 3 needs to be pressed against the first roller 52 and the second roller 53. The movement of the first roller 52 and the second roller 53 can save more effort. At this time, cable 3 may shake during cutting. The damping device 61 makes the first roller 52 have a shock absorption effect, thereby reducing the amplitude of cable 3 shaking. The surfaces of the first roller 52 and the second roller 53 are provided with anti-slip textures, which further reduce the amplitude of cable 3 shaking.

[0042] Furthermore, by allowing the damping device 61 and the roller connecting shaft 6 to slide in the slide groove 63 and the limiting groove 64 respectively, the first roller 52 is driven to move. By changing the distance between a pair of first rollers 52, the first roller 52 can better fit the cable 3. After adjusting the angle, the damping device 61 is fixed by tightening the limiting nut 62.

[0043] Working principle: During operation, rotating the threaded rod 21 drives the blade 25 to move within the workpiece 1. The thread allows for more precise movement of the blade 25. Through the action of the cutter shaft 26, the blade 25 can rotate within the blade support 24, thereby achieving the cutting function.

[0044] When placing cable 3, cable 3 needs to be pressed against the first roller 52 and the second roller 53. The movement of the first roller 52 and the second roller 53 can save more effort. At this time, cable 3 may shake when cutting. The damping device 61 makes the first roller 52 have a shock absorption effect, thereby reducing the amplitude of cable 3 shaking.

[0045] Furthermore, by allowing the damping device 61 and the roller connecting shaft 6 to slide in the slide groove 63 and the limiting groove 64 respectively, the first roller 52 is driven to move. By changing the distance between a pair of first rollers 52, the first roller 52 can better fit the cable 3. After adjusting the angle, the damping device 61 is fixed by tightening the limiting nut 62.

[0046] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
