DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0017] In the related art, when connecting a cable to a terminal system, it is necessary to cut and remove the bellows outside the cable. The commonly used cutting tool is an electrician's knife, and the cutting quality is affected by the proficiency of the operator, and it is difficult to ensure the flatness of the cutting surface.
[0018] This embodiment provides a cable bellows cutting and limiting device, which can ensure the flatness of the cutting surface.
[0019] Please refer to Figures 1-3 , in this embodiment, a cable bellows cutting and limiting device includes a frame body 10 and a sliding sleeve 20; the frame body 10 has two opposite end portions 11, the end portions 11 have limiting surfaces 12 arranged along the axial direction, and knobs 13 are screwed onto the end portions 11; the sliding sleeve 20 is slidably inserted into the end portions 11, the sliding sleeve 20 has a connecting portion 21, the knobs 13 are restricted within the connecting portion 21, and limiting wheels 22 are provided on the sliding sleeve 20; wherein, a triangular structure for clamping the bellows 30 in the circumferential direction is formed by the cutting knife 14 and the two limiting wheels 22 in the middle of the frame body 20.
[0020] Adopting the technical solution of this embodiment, by rotating the knob 13 to drive the limiting wheel 22 to press against the corrugated pipe 30, the pressing of the two limiting wheels 13 against the corrugated pipe 30 can cause the cutting knife 14 to cut into the corrugated pipe 30. The cutting knife 14 follows the rotation of the frame body 10 to circumferentially cut the corrugated pipe 30, which can ensure the flatness of the cutting surface.
[0021] In this embodiment, both ends of the frame body 10 are bent towards each other to form two coaxial ends 11, and the two ends are symmetrically arranged on the frame body 10. The end 11 is integrally constructed as a longitudinally long cylindrical shape. The end 11 has an external thread. At the same time, a limiting surface 12 extending along its axial direction is provided on the outer wall of the end 11. The limiting surface 12 is a plane, and two limiting surfaces 12 are uniformly arranged along the circumferential direction of the end 11. The arc between the two limiting surfaces 12 is a major arc. The knob 13 is screwed onto the end 11, and the knob 13 is constructed as a circular shape coaxial with the end 11.
[0022] In this embodiment, the sliding sleeve 20 is integrally constructed as a hollow circular tubular shape. The inner wall of the sliding sleeve 20 is smooth. The sliding sleeve 20 is slidably sleeved on the outside of the end 11. In order to prevent the sliding sleeve 20 from rotating around the end 11, a guiding surface 23 that fits with the limiting surface 12 is provided on the inner wall of the sliding sleeve 20.
[0023] In addition, a rotatable limiting wheel 22 is provided at one end of the sliding sleeve 20 close to the corrugated pipe 30, and the axis of the limiting wheel 22 is parallel to the axis of the corrugated pipe 30. The arc between the two limiting wheels 22 on the side away from the cutting knife 14 is a minor arc. The cutting knife 14 is fixedly connected to the middle position of the frame body 10. The two ends 11 are symmetrically arranged on both sides of the cutting knife 14. The two limiting wheels 22 are symmetrically arranged on both sides of the cutting knife 14. When the two limiting wheels 22 press against the corrugated pipe 30, they will push the corrugated pipe 30 towards the cutting knife 14 so that the cutting knife 14 can cut into the corrugated pipe 30.
[0024] In addition, a connecting portion 21 is fixedly connected to one end of the sliding sleeve 20 away from the corrugated pipe 30. The connecting portion 21 is integrally constructed as an annular shell shape. The connecting portion 21 is coaxial with the sliding sleeve 20. The connecting portion 21 is integrally wrapped outside the knob 13, so that the rotation of the knob 13 is restricted inside the connecting portion 21. The screwing of the knob 13 on the end 11 will drive the connecting portion 21 and the sliding sleeve 20 to move synchronously along the axial direction.
[0025] For convenient operation, an avoidance opening 24 is provided on the connecting portion 21. The avoidance opening 24 enables the operator's hand to contact the knob 13 and rotate the knob 13.
[0026] In use, move the corrugated pipe 30 into the interior of the frame body 10 between the two limit wheels 22, then rotate the knob 13 so that the two limit wheels 22 are pressed against the corrugated pipe 30 until the cutting knife 14 cuts into the interior of the corrugated pipe 30. Finally, rotate the frame body 10, and the cutting knife 14 rotates synchronously with the frame body 10 to complete the circumferential cutting of the corrugated pipe 30.
[0027] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application.
