Description

Technical Field

[0001] The invention relates to the technical field of safety protection, in particular to a wire locking rod. Background Art

[0002] During the laying, maintenance and inspection of wires and cables, operators often need to use various tools to grab, fix and move wires or cables. Among them, the operating rod, as a common tool, plays an important role.

[0003] When existing operating levers are used to grab wires and cables in cold and humid environments, the surface of the cable may freeze or become damp, resulting in reduced friction between it and the hook, further increasing the risk of slipping. In addition, for cables with soft or easily deformed outer walls, in high temperature environments, the outer wall materials such as rubber and plastic will soften and become more sticky, making them more likely to adhere to the hook and difficult to fall off, increasing the probability of the cable outer wall getting stuck.

[0004] Based on the above problems, we propose a wire locking rod. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is that the existing operating rod hook is easy to slip in a cold and humid environment. After the operator grabs the cable for a long time, it is easy to get stuck and difficult to fall off due to deformation of the cable outer wall, fatigue and environmental factors.

[0006] The above technical problems are solved by the following technical solutions: a wire locking assembly, including a hook body and a movable block slidingly arranged on the outer wall of the hook body; a support assembly, including a movable rod arranged under the hook body and a connecting rod movably connected to the movable rod; the hook body includes an arc-shaped hook, and a plurality of first anti-slip grooves are evenly distributed on the inner wall of the arc-shaped hook, and two adjacent first anti-slip grooves are staggered in the arc direction.

[0007] In a preferred embodiment of the wire locking rod of the present invention, the hook body further comprises an upright portion and a receiving portion, and slots are formed on both sides of the upright portion and outer walls of the arc-shaped hook.

[0008] In a preferred embodiment of the wire locking rod of the present invention, a groove is formed on a side of the movable block close to the hook body.

[0009] In a preferred embodiment of the wire locking rod of the present invention, the groove is in sliding engagement with a protrusion between the two notches.

[0010] In a preferred embodiment of the wire locking rod of the present invention, an outer wall of the movable block on a side close to the arc-shaped hook is provided with an arc-shaped surface.

[0011] In a preferred embodiment of the wire locking rod of the present invention, a plurality of second anti-slip grooves are evenly formed on the outer wall of the arc-shaped surface.

[0012] In a preferred embodiment of the wire locking rod of the present invention: a screw rod is provided on the outer wall of the movable block away from the arc-shaped hook, and a screw rod nut hole is formed through the outer wall of the receiving portion.

[0013] In a preferred embodiment of the wire locking rod of the present invention, one end of the screw rod is connected to the movable block, and the other end passes through the screw rod nut hole and is connected to the movable rod.

[0014] In a preferred embodiment of the wire locking rod of the present invention, a threaded hole is formed at one end of the movable rod away from the hook body.

[0015] In a preferred embodiment of the wire locking rod of the present invention: one end of the connecting rod is provided with a threaded rod adapted to the threaded hole, and the other end is provided with a handle.

[0016] The beneficial effect of the present invention is that: through the staggered arrangement of the first anti-slip grooves designed on the inner wall of the arc-shaped hook, multiple points of contact are formed between the cable and the inner wall of the arc-shaped hook, rather than the traditional surface-to-surface contact method, which can increase the friction between the cable and the hook body, preventing the cable from slipping during the grabbing process, and avoiding the jamming problem caused by deformation and fatigue of the outer wall of the cable when grabbing the cable for a long time.

[0021] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0022] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0023] Reference Figures 1 to 3 The present embodiment provides a wire locking rod, including a wire locking assembly 1, including a hook body 11 and a movable block 12 slidably provided on the outer wall of the hook body 11; the hook body 11 is used to grab the cable, and the movable block 12 is slidably provided on the outer wall of the hook body 11, and can flexibly adjust its position according to the diameter of the cable. When the cable is thin, the sliding movable block 12 is close to the arc-shaped hook 111, reducing the distance between the hook body 11 and the movable block 12, thereby clamping the cable; when the cable is thick, the sliding movable block 12 is away from the arc-shaped hook 111, expanding the distance, so that the cable can be smoothly inserted and clamped.

[0024] The support assembly 2 includes a movable rod 21 provided under the hook body 11 and a connecting rod 22 movably connected to the movable rod 21; the movable rod 21 is movably provided under the hook body 11 to play a supporting and adjusting role, and the position of the movable block 12 can be adjusted according to the thickness of the cable to provide stable support for the wire locking assembly 1; the connecting rod 22 is movably connected to the movable rod 21 through a thread, and the operator can adjust the length of the support assembly 2 by rotating the connecting rod 22. When the cable is far away, by extending the support assembly 2, the operator can more easily reach and grab the distant cable without forcibly pulling the cable, thereby avoiding unnecessary damage to the cable.

[0025] like Figure 2 As shown, the hook body 11 includes an arc-shaped hook 111, and a plurality of first anti-slip grooves 112 are evenly distributed on the inner wall of the arc-shaped hook 111, and two adjacent first anti-slip grooves 112 are staggered in the arc direction; the arc-shaped design of the arc-shaped hook 111 can fit the circular surface of the cable, ensuring that the hook body 11 can firmly surround the cable, and the staggered first anti-slip grooves 112 improve the uniform distribution of friction, avoiding the risk of the cable slipping due to force in a single direction, and the staggered first anti-slip grooves 112 can effectively disperse the pressure, so that the outer wall of the cable and the inner wall of the arc-shaped hook 111 are in surface-to-surface contact, which is transformed into multi-point contact, reducing local extrusion and thus reducing the possibility of irreversible deformation of the outer wall of the cable during long-term grasping, ensuring that the cable can fall off from the hook body smoothly, and improving work efficiency and safety.

[0026] As an optional embodiment, the hook body 11 also includes an upright portion 113 and a receiving portion 114, and slots 115 are provided on the outer walls on both sides of the upright portion 113 and the arc-shaped hook 111; the upright portion 113 and the arc-shaped hook 111 form a whole, so that the hook body 11 can withstand a greater gripping force and prevent deformation when grabbing heavier or thicker cables; the receiving portion 114 is located below the hook body 11, connecting the hook body 11 and the movable rod 21, and through the cooperation of the screw rod 124 and the screw rod nut hole 125, an adjustable connection relationship is formed between the movable block 12 and the movable rod 21; the slots 115 are provided on the outer walls on both sides of the upright portion 113 and the arc-shaped hook 111, providing a sliding track for the groove 121 of the movable block 12, and providing a guiding effect on the sliding of the movable block 12, and limiting the moving range of the movable block 12, ensuring that the movable block 12 is accurately positioned on the hook body 11.

[0027] As an optional embodiment, a groove 121 is provided on the side of the movable block 12 close to the hook body 11, and the protrusion 116 between the groove 121 and the notch 115 on the outer wall of both sides of the hook body 11 slides together, so that the movable block 12 can slide stably on the outer wall of the hook body 11, ensuring a tight fit between the movable block 12 and the hook body 11.

[0028] As an optional embodiment, the groove 121 slides with the protrusion 116 between the two notches 115, and the groove 121 of the movable block 12 slides with the protrusion 116 of the hook body 11, ensuring the sliding stability of the movable block 12 and ensuring that the movable block 12 will not deviate or shake during the grasping process.

[0029] As an optional embodiment, the outer wall of the movable block 12 close to the arc-shaped hook 111 is provided with a curved surface 122; the curved surface 122 enables the movable block 12 to fit closely to the surface of the cable, and a gripping space can be formed between the curved surface 122 and the arc-shaped hook 111. The arc shape of the curved surface 122 and the inner wall of the arc-shaped hook 111 can make the cable evenly stressed when being gripped, reducing local stress concentration; further, the design of the curved surface 122 can enable the movable block 12 to better adapt to changes in cable diameter. When the movable block 12 slides to adjust its position, the curved surface 122 can maintain a good fit with the cable surface, ensuring effective transmission of the gripping force.

[0030] As an optional embodiment, a plurality of second anti-slip grooves 123 are evenly provided on the outer wall of the arc-shaped surface 122. The second anti-slip grooves 123 increase the friction between the movable block 12 and the cable, effectively preventing the cable from slipping during the grabbing process. The second anti-slip grooves 123 work together with the first anti-slip grooves 112 in the arc-shaped hook 111 to further enhance the gripping force of the cable, so that the cable can be firmly clamped between the hook body 11 and the movable block 12.

[0031] As an optional embodiment, a screw rod 124 is provided on the outer wall of the movable block 12 away from the arc-shaped hook 111. The screw rod 124 is fixedly arranged on the outer wall of the movable block 12, and a screw nut hole 125 is penetrated through the outer wall of the receiving portion 114. The screw rod 124 and the screw nut hole 125 are connected by threaded cooperation, so that a stable mechanical connection is formed between the movable block 12 and the receiving portion 114; by rotating the movable rod 21 or the connecting rod 22, the relative position between the movable rod 21 and the receiving portion 114 can be changed, driving the screw rod 124 to rotate in the screw nut hole 125, so that the movable block 12 slides along the outer wall of the hook body 11, and the distance between the hook body 11 and the movable block 12 is adjusted to adapt to cables of different diameters.

[0032] As an optional embodiment, one end of the screw rod 124 is fixedly connected to the movable block 12, and the other end passes through the screw rod nut hole 125 and is fixedly connected to the movable rod 21. The cooperation between the screw rod 124 and the screw rod nut hole 125 enables the movable block 12 to be adjusted in position according to the needs of the operator.

[0033] like Figure 3 As shown, as an optional embodiment, a threaded hole 211 is formed at one end of the movable rod 21 away from the hook body 11 , and the threaded hole 211 is used to cooperate with the threaded rod 221 of the connecting rod 22 to achieve a detachable connection between the movable rod 21 and the connecting rod 22 .

[0034] As an optional embodiment, a threaded rod 221 that is compatible with the threaded hole 211 is provided at one end of the connecting rod 22, and a handle 222 is provided at the other end. By rotating the connecting rod 22, the threaded rod 221 rotates in the threaded hole 211, and the relative position between the movable rod 21 and the connecting rod 22 can be accurately adjusted. The length of the support assembly 2 can be flexibly adjusted to adapt to the cable grabbing requirements of different heights or distances. The setting of the handle 222 provides the operator with a comfortable force point, which is convenient for the operator to hold.

[0035] When in use, the operator first adjusts the length of the connecting rod 22 according to the diameter and position of the cable, and applies force through the grip 222 to make the hook body 11 close to the cable, and rotates the threaded rod 221 at one end of the connecting rod 22 to make the threaded rod 221 rotate in the threaded hole 211 of the movable rod 21, thereby extending and retracting the movable rod 21, driving the groove 121 on the movable block 12 to slide along the protrusion 116, and adjusting the distance between the hook body 11 and the movable block 12; when adjusted to the appropriate position, the arc The first anti-slip groove 112 on the inner wall of the hook 111 and the second anti-slip groove 123 on the movable block 12 work together to firmly clamp the cable; when the cable needs to be released, the connecting rod 22 is rotated in the opposite direction to drive the movable block 12 away from the arc-shaped hook 111, thereby increasing the distance between the arc-shaped hook 111 and the movable block 12. Due to the design of the first anti-slip groove 112 and the second anti-slip groove 123, multiple points of contact are formed between the cable and the hook body 11, and the outer wall of the cable will not be stuck on the inner wall of the arc-shaped hook 111, so the cable can be easily released.

[0036] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
