Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable fixing technology, specifically to a low-voltage cable fixing device. Background Technology
[0002] Low-voltage cables are mainly used for information transmission, such as signals, audio, and video. They typically operate at voltages below 220V, with low current and power, and at higher frequencies, requiring the assurance of signal transmission fidelity and reliability.
[0003] Existing low-voltage cables are typically secured using cable ties or limit clips. Cable ties, in particular, are inconvenient for cable maintenance. While limit clips can secure cables, they are not always straight during the cable arrangement process. After being rigidly secured, cables are prone to twisting as they bend. Furthermore, once secured, cables are easily pulled by external forces due to the lack of buffer. Utility Model Content
[0004] The technical problem this invention aims to solve is that cable ties are inconvenient for maintenance, and the rigid fixation of the limit buckle makes the cable prone to twisting at bends; after fixing, the cable lacks buffer and is easily pulled off.
[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a low-voltage cable fixing device, including a mounting plate and a plurality of limiting buckles that can limit the cable position, the limiting buckles being evenly distributed in an array on the mounting plate.
[0006] The limiting buckles are arranged in pairs and are located on both sides of the mounting plate. Between the relative limiting buckles, there is a buffer assembly that can buffer the cable to prevent it from being pulled off by force. The buffer assembly includes an L-shaped hinge shaft that is hinged to the middle of the mounting plate by a torsion spring. The free end of the hinge shaft is provided with a fixed rod, and a sliding sleeve is slidably provided on the fixed rod. A guide wheel is rotatably provided on the outside of the sliding sleeve. The limiting buckles are provided with an automatic adjustment assembly, which can achieve clamping and limiting of cables of different diameters.
[0007] Furthermore, the limiting buckle includes a base plate and limiting clips that are symmetrically arranged on both sides of the base plate and have elasticity. The middle part of the limiting clips converges towards the middle of the base plate and the free end expands outward.
[0008] Furthermore, the automatic adjustment component includes a slide rod connected to the bottom end of the limiting clamp, the slide rod slides through the base plate and has a limiting plate at its end, and a first spring sleeved on the outside of the slide rod is provided between the limiting plate and the base plate.
[0009] Furthermore, a rotating rod is provided at the center of the bottom end of the base plate, and the rotating rod is rotatably connected to the mounting plate.
[0010] Furthermore, the guide wheel is provided with an arc-shaped groove in the circumference.
[0011] The advantages of this utility model compared with the prior art are as follows:
[0012] 1. By setting up a buffer component, the hinge shaft, through the action of the torsion spring, drives the connection between the hinge shaft and the limit buckle to form a certain angle, thereby buffering the cable between a set of limit buckles and preventing the cable from being easily pulled off.
[0013] 2. The multiple sets of limit buckles and automatic adjustment components make it easy to limit the movement of multiple cables of different diameters, which improves practicality and facilitates maintenance. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] Combined with appendix Figure 1 and attached Figure 4A low-voltage cable fixing device includes a mounting plate 1 and a plurality of limiting buckles 2 for limiting the cable. The limiting buckles 2 are evenly arranged on the mounting plate 1. Each limiting buckle 2 includes a base plate 10 and a limiting clip 9 that is symmetrically arranged on both sides of the base plate 10 and has elasticity. The middle part of the limiting clip 9 converges towards the middle of the base plate 10 and the free end expands outward. A rotating rod 14 is provided at the middle of the bottom end of the base plate 10, and the rotating rod 14 is rotatably connected to the mounting plate 1.
[0021] The rotation of the rotating rod 14 allows the limit clamp 9 to twist to a certain extent on the surface of the mounting plate 1 according to the cable installation requirements, thus preventing the cable from twisting due to changes in the installation angle and thus protecting the cable at the corner.
[0022] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 3 The limiting buckles 2 are arranged in pairs and are located on both sides of the mounting plate 1. A buffer assembly 3 is provided between the limiting buckles 2 to buffer the cable and prevent the cable from being pulled off by force. The buffer assembly 3 includes a hinge shaft 4 with an L-shaped structure that is hinged to the middle of the mounting plate 1 by a torsion spring. A fixed rod 5 is provided at the free end of the hinge shaft 4. A sliding sleeve 6 is slidably provided on the fixed rod 5. A guide wheel 7 is rotatably provided outside the sliding sleeve 6. The guide wheel 7 is provided with an arc groove 15 in the circumference.
[0023] The buffer component 3 allows for the pre-storage of a portion of the cable between the paired limit buckles 2, preventing the cable from being pulled apart due to a sudden increase in pressure applied to the cable during installation or use.
[0024] By winding the cable between the relative limit buckles 2 onto the guide wheel 7, a 90° right-angle bend in the cable is prevented. In its natural state, the torsion spring drives the hinge shaft 4 so that the center of the guide wheel 7 is not on the straight line of the relative limit buckles 2. At this time, the guide wheel 7 opens and stores the cable. When the cable is subjected to external force, it needs to overcome the deformation caused by the torsion spring first, and then release the pre-buried cable to avoid damage caused by the hard pulling of the cable. The matching arrangement of the fixing rod 5, the sliding sleeve 6 and the guide wheel 7 makes it easy for cables of different diameters to fit into the middle of the arc groove 15 on the guide wheel 7, preventing them from easily detaching from the guide wheel 7.
[0025] Combined with appendix Figure 4 The limit buckle 2 is equipped with an automatic adjustment component 8. The limit buckle 2 can clamp and limit cables of different diameters through the automatic adjustment component 8. The automatic adjustment component 8 includes a slide rod 11 connected to the bottom end of the limit clamp 9. The slide rod 11 slides through the base plate 10 and has a limit plate 12 at its end. A first spring 13 is provided between the limit plate 12 and the base plate 10 and sleeved on the slide rod 11.
[0026] The cable is squeezed inward from the free end of the relative limiting clamp 9 and guided between the bottom of the limiting clamp 9. The converging part in the middle of the limiting clamp 9 can temporarily limit the cable. Under the action of the first spring 13, the slide rod 11 drives the limiting clamp 9 downward, thereby limiting cables of various diameters between the limiting clamp 9 and the base plate 10.
