Description

Technical Field

[0001] This utility model relates to the field of cable management technology, and in particular to a cable management and fixing device for electrical installation. Background Technology

[0002] In electrical installation and wiring projects, cable organization and fixing devices are essential components. Their main function is to neatly fix cables and wire harnesses to walls, cabinets, or equipment brackets to ensure that the wiring is aesthetically pleasing, safe, and orderly.

[0003] Existing cable fixing devices, such as common pipe clamps or clips, are usually quite simple in structure. Once the cable is fixed during installation, its direction and angle are determined. If subsequent adjustments to the wiring layout are needed, or if it is discovered during installation that the cable route needs to be changed, the entire fixing device often needs to be disassembled and reinstalled. This is very inconvenient, especially in confined spaces or in areas where some renovations have already been completed, where the difficulty and workload of adjustments are even greater.

[0004] Furthermore, the clamping parts of these types of fixing devices typically rely on bolt tightening or simple snap-fit ​​structures for locking and unlocking. While bolt tightening is reliable, it is inefficient in situations requiring frequent operation. Simple snap-fit ​​structures, although easy to open, have limited locking force, poor reliability, and are prone to wear and tear after prolonged use, leading to locking failure. Additionally, these traditional fixing methods provide a fixed clamping force, unable to adapt to slight cable movement or thermal expansion and contraction. Over time, gaps can easily form between the cable and the clamp, causing the cable to loosen and affecting the fixing effect.

[0005] Therefore, this utility model proposes a cable organization and fixing device for electrical appliance installation to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing cable management and fixing devices during electrical appliance installation, such as the difficulty in adjusting the laying direction of the cable after fixing and the cumbersome and time-consuming locking and releasing operation of the clamping mechanism, this utility model aims to provide a cable management and fixing device for electrical appliance installation with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a cable organization and fixing device for electrical installation, including: a base, a main ring, and a secondary ring; as well as an internal threaded ring, a rotating block, wheel teeth, a disc spring, and a pre-tightening mechanism.

[0008] The internal threaded ring is fixedly mounted on the inner wall of the base, while the rotating block and gear teeth are mounted on the main ring.

[0009] Furthermore, the gear teeth mesh with the internal threaded ring under the elastic force of the disc spring to restrict the rotation of the main ring, and the main ring and the auxiliary ring are locked together by a pre-tightening mechanism.

[0010] Preferably, by pressing the main ring, the rotating block and gear teeth move downward, causing the gear teeth to disengage from the internal threaded ring, thereby adjusting the orientation of the main ring and the secondary ring.

[0011] Preferably, the pre-tightening mechanism includes a first fixing block and a second fixing block respectively disposed on the main ring and the secondary ring, a pressure plate, a connecting column, a limiting rod and a second spring; the second fixing block is provided with a through hole and a groove located at its bottom, and the second spring is disposed between the first fixing block and the pressure plate.

[0012] Preferably, by pressing the pressure plate, the connecting column and the limiting rod are moved, so that the limiting rod passes through the through hole of the second fixing block, and the limiting rod is rotated to align with the groove. Under the action of the second spring, the limiting rod is finally locked into the groove.

[0013] Preferably, the connecting column is set vertically, with a pressure plate connected to its upper end and a limiting rod connected to its lower end.

[0014] Preferably, the cable management and fixing device during electrical installation also includes a clamping block, a piston, and a spring, which are disposed on the inner wall of the main ring or the secondary ring. The spring pushes the clamping block to continuously press against the cable through the piston.

[0015] Preferably, the secondary ring is connected to the main ring via a hinged structure to allow for swinging opening or clamping of the cable.

[0016] Preferably, the base is provided with a connecting plate, and the connecting plate is provided with mounting holes for bolts to pass through.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting a rotary positioning mechanism composed of a disc spring, gear teeth and an internal threaded ring, allows the orientation to be adjusted by pressing the main ring to disengage the gear teeth from the internal threaded ring. This solves the problem of difficulty in adjusting the laying angle after the cable fixing device is installed in the prior art, and achieves the technical effect of being able to quickly and conveniently change the cable direction, with flexible and convenient operation.

[0019] 2. This utility model, by setting a pre-tightening mechanism consisting of a pressure plate, a limiting rod, and a fixing block with a groove, solves the problem of cumbersome and inefficient locking and unlocking operations of the clamping mechanism in the prior art through a simple action of pressing-rotating-releasing the limiting rod. It achieves the technical effect of quickly fixing and opening the clamping ring, and significantly improving the efficiency of installation and maintenance.

[0020] 3. This utility model solves the problem of fixed clamping force and easy loosening when the cable shakes in the prior art by setting an elastic clamping structure composed of spring, piston and clamping block in the ring body. It achieves the technical effect of continuously applying elastic clamping force to the cable, adaptively compensating for gaps, effectively preventing loosening, and making the clamping more stable and reliable.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0028] Please refer to Figures 1 to 4 A cable management and fixing device for electrical installation includes a base 1, a main ring 9 rotatably mounted on the base 1, and a secondary ring 10 operably connected to the main ring 9. The base 1 serves as the mounting base for the entire device, and the main ring 9 and the secondary ring 10 cooperate to clamp the cable and adjust the orientation of the cable.

[0029] Please refer to Figure 2An internal threaded ring 5 is fixedly connected to the inner wall of the base 1. A rotating block 6 and a gear tooth 7 are provided on the main ring 9. A disc spring 8 is located between the rotating block 6 and the main ring 9. In its natural state, the spring force of the disc spring 8 pushes the rotating block 6 and the gear tooth 7 upward, so that the gear tooth 7 meshes with the internal threaded ring 5, thereby restricting the rotation of the main ring 9. When the main ring 9 is pressed down, the main ring 9 drives the rotating block 6 and the gear tooth 7 to move downward against the spring force of the disc spring 8, so that the gear tooth 7 disengages from the internal threaded ring 5. At this time, the main ring 9 and the secondary ring 10 can be rotated freely to adjust the direction of the cable.

[0030] Please refer to Figure 3 and Figure 4 The pre-tightening mechanism 2 is used for quickly locking and releasing the secondary ring 10. It includes a first fixing block 11 and a second fixing block 12, which are respectively fixedly connected to the main ring 9 and the secondary ring 10. The second fixing block 12 has a through hole and a groove at its bottom. The pre-tightening mechanism 2 also includes a pressure plate 206, a connecting post 204, a limiting rod 205, and a second spring 207. The upper end of the connecting post 204 is connected to the pressure plate 206, and its lower end is connected to the limiting rod 205. The second spring 207 is sleeved on the outer periphery of the connecting post 204. It is accommodated between the fixing block 11 and the pressure plate 206. After the secondary ring 10 is closed, the pressure plate 206 is pressed down. The pressure plate 206 drives the connecting column 204 and the limiting rod 205 to move down, so that the limiting rod 205 passes through the through hole of the fixing block 12. Then, the limiting rod 205 is rotated to align with the groove at the bottom of the fixing block 12. After the pressure plate 206 is released, the spring 207 pushes the pressure plate 206 to return to its original position, so that the limiting rod 205 is locked into the groove, thereby completing the locking of the secondary ring 10.

[0031] As a preferred embodiment, to achieve adaptive elastic clamping of the cable and prevent it from loosening due to shaking, please refer to... Figure 3 The inner side of the main ring 9 or the secondary ring 10 is provided with a clamping block 203, a piston 201 and a spring 202. The spring 202 pushes the clamping block 203 inward through the piston 201 so as to elastically and tightly adhere to the clamped cable.

[0032] As another preferred embodiment, for ease of cable insertion and removal, please refer to... Figure 1 The secondary ring 10 is connected to the main ring 9 by a hinge to achieve swing opening or closing relative to the main ring 9.

[0033] As another preferred embodiment, for easy and reliable mounting of the entire device on a wall or object, please refer to... Figure 1 and Figure 2 A connecting plate 3 is fixedly connected to the base 1, and the connecting plate 3 has mounting holes for bolts 4 to pass through.

[0034] As a further optimization of the preload mechanism 2, to clarify the internal force transmission path, please refer to... Figure 4The connecting column 204 is set vertically, with its upper end fixedly connected to the pressure plate 206 and its lower end fixedly connected to the limiting rod 205.

[0035] Working principle: Align the connecting plate 3 with the connecting hole, and use bolts 4 to fix the base 1 to the object and wall. Press down on the main ring 9, causing the rotating block 6 to drive the gear 7 to move down, so that the gear 7 moves away from the internal thread ring 5. Then rotate the main ring 9, so that the main ring 9 and the secondary ring 10 are oriented in the desired direction. Release the main ring 9, and the disc spring 8 pushes the rotating block 6 and the gear 7 to move up, so that the gear 7 re-engages with the internal thread ring 5. Since the internal thread ring 5 is fixed to the inner wall of the base 1, the main ring 9 and the secondary ring 10 are restricted and no longer rotate. By swinging the secondary ring 10 up and down, the secondary ring 10 is rotated, thereby opening and clamping the cable, thus realizing the adjustment of the cable turning and orientation at any time.

[0036] The main ring 9 and the secondary ring 10 clamp and fix the cable. At the same time, the cable will push the clamping blocks 203 away from each other. When shaking occurs, the spring 1 202 pushes the clamping blocks 203 to keep them close to the cable through the piston 201, aligning the limiting rod 205 with the through hole of the fixing block 2 12. The pressure plate 206 is pressed down, which drives the connecting column 204 and the limiting rod 205 to move down and pass through the fixing block 2 12. The limiting rod 205 is rotated so that it is aligned with the groove at the bottom of the fixing block 2 12. Then the pressure plate 206 is released. Due to the support of the fixing block 1 11, the spring 2 207 pushes the pressure plate 206 to move upward, so that the limiting rod 205 is inserted into the groove at the bottom of the fixing block 2 12. This achieves the pre-tightening of the cable by the pre-tightening mechanism 2 and its rapid opening and fixing.
