Description

Technical Field

[0001] This utility model relates to the field of wiring device technology, and in particular to an electrical room wiring device. Background Technology

[0002] Electrical room wiring systems refer to the systematic facilities used in electrical rooms for the safe, standardized laying, fixing, and management of power cables, control cables, and related electrical equipment. These systems include components such as cable trays, cable ducts, conduits, distribution panels, terminal blocks, and grounding devices. Their core function is to ensure the reliability of power and signal transmission, prevent messy wiring, short circuits, or electromagnetic interference, and facilitate maintenance and expansion. The design must comply with electrical safety standards (such as insulation, fire protection, and moisture protection requirements), rationally plan routes to optimize space utilization, and consider future expansion needs. It is an indispensable infrastructure in industrial, commercial, and residential power distribution systems.

[0003] A wiring device with prior art disclosure number CN221487256U includes a placement block, a placement groove on the top surface of the placement block, and a plurality of adjusting blocks movably fitted inside the placement groove; a positioning ring, which is fixedly connected to the top surface of the adjusting block, and two elastic blocks are fixedly connected to the inner circular wall of the positioning ring; and a fixing component, which is disposed inside the placement groove.

[0004] Although the device can adapt to different numbers of wires by adding or removing fixing components, it still has two limitations in practical applications: First, the traditional circular positioning ring must be fixed by threading, which cannot achieve open and quick snap-fit, increasing the difficulty of construction at high altitudes or in narrow spaces; Second, the base length of the fixing module cannot be changed. When the number of wires does not match the module capacity, it will cause space waste or excessive compression, which will affect the aesthetics of the wiring.

[0005] Therefore, an electrical room wiring device is proposed. Utility Model Content

[0006] This utility model is a wiring device for electrical rooms proposed to overcome the shortcomings of existing technologies.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: an electrical room wiring device, comprising multiple adjusting blocks, each of which has a mounting groove on its top. The mounting slots are equipped with first bidirectional screws, and both ends of the first bidirectional screws extend through the inner wall of the mounting slots to the outer side of the adjusting block. Two wire clamps are symmetrically threaded onto the outer surfaces of the multiple first bidirectional screws. A spline hole is provided at one end of each of the first bidirectional screws; A handwheel is fixedly connected to the other end of a single first bidirectional screw, and a splined shaft is fixedly connected to the other end of the remaining multiple first bidirectional screws. Locking grooves are provided on both sides of the outer surface of each of the multiple adjusting blocks; Except for the single adjusting block located on one side of the handwheel, the remaining multiple adjusting blocks are all equipped with locking components.

[0008] Furthermore, mounting plates are fixedly connected to both sides of the outer surface of the multiple adjustment blocks, and mounting holes extending from the top to the bottom are opened on the top of the multiple mounting plates. This structure allows the adjustment blocks to be directly fixed to the wall or bracket of the electrical room by bolts or screws, making the installation method flexible.

[0009] Furthermore, all of the first bidirectional screws are rotatably connected to the adjusting block, and the adjusting block facilitates the installation of the first bidirectional screws.

[0010] Furthermore, all of the aforementioned wire clamps slide against the inner walls on both sides of the adjacent mounting groove. The cooperation between the wire clamps and the inner walls of the mounting groove can prevent skewing during the clamping process and ensure that the wires are clamped evenly.

[0011] Furthermore, each of the locking components includes a second bidirectional screw, which is set completely through the adjacent adjusting block and is rotatably connected to the adjusting block. One end of each second bidirectional screw is fixedly connected to a knob, which facilitates manual driving of the second bidirectional screw.

[0012] Furthermore, the outer surface of the second bidirectional screw is symmetrically threaded with two sliders, and one end of each slider is fixedly connected with a locking wedge. The locking wedge and the locking groove cooperate through the inclined surface to generate an axial locking force. The bidirectional screw drives the sliders to move synchronously relative to each other, so that the locking wedge is stably pushed along the groove.

[0013] Furthermore, a sliding plate is fixedly connected to one side of the outer surface of each of the two sliders, and the sliding plate slides in contact with the outer wall of the adjusting block. The sliding cooperation between the sliding plate and the outer wall of the adjusting block can restrict the rotational freedom of the slider, so that it can only move along the screw axis, thereby improving the stability and reliability of the locking mechanism.

[0014] The beneficial effects of this utility model are: In use, this utility model, an electrical room wiring device, effectively solves two major technical defects of traditional wiring devices through the innovative combination of modular adjustment blocks and linkage clamping mechanisms: Firstly, By setting a symmetrical clamping plate driven by a bidirectional screw on the top of the adjusting block, an open adjustable clamping structure is formed to replace the traditional closed positioning ring, allowing wires to be quickly installed through lateral clamping, which is especially suitable for one-handed operation in high-altitude or narrow spaces. Secondly, the combination of spline shaft and spline hole plugging is used to realize multi-module linkage. With the synergistic effect of locking groove and locking component, the adjusting block can be freely added or removed according to the number of cables while keeping the spacing between each module adjustable. This not only eliminates the space waste caused by fixed module capacity, but also allows the synchronous opening and closing of all clamping plates to be controlled by handwheel, avoiding local overpressure problems when multiple lines are arranged side by side, and significantly improving wiring efficiency and neatness.

[0018] 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.

[0019] As shown in Figure 1 to Figure 4 As shown, an electrical room wiring device is disclosed, comprising multiple adjusting blocks 1, multiple... Mounting plates 5 are fixedly connected to both sides of the outer surface of the adjusting block 1, and mounting holes 4 extending through to the bottom are opened on the top of the multiple mounting plates 5.

[0020] Each of the multiple adjusting blocks 1 has a mounting groove 11 on its top. Each of the multiple mounting grooves 11 has a first bidirectional screw 9 inside. Both ends of the first bidirectional screw 9 extend through the inner wall of the mounting groove 11 to the outer side of the adjusting block 1. The multiple first bidirectional screws 9 are rotatably connected to the adjusting block 1. The outer surfaces of the multiple first bidirectional screws 9 are symmetrically threaded with two wire clamps 3. The multiple wire clamps 3 slide against the inner walls on both sides of the adjacent mounting grooves 11. The thread helix angle of the first bidirectional screw 9 is smaller than the friction angle, which gives the first bidirectional screw 9 a self-locking ability and can prevent it from shifting due to vibration or load.

[0021] Each of the multiple first bidirectional screws 9 has a spline hole 13 at one end.

[0022] A handwheel 2 is fixedly connected to the other end of a single first bidirectional screw 9, and multiple remaining first bidirectional screws... The other end of 9 is fixedly connected to a spline shaft 8.

[0023] Locking grooves 12 are provided on both sides of the outer surface of multiple adjusting blocks 1.

[0024] Except for the single adjusting block 1 located on one side of the handwheel 2, the remaining multiple adjusting blocks 1 are all equipped with locking components. Each locking component includes a second bidirectional screw 14, which is set to completely penetrate the adjacent adjusting block 1 and is limited to a rotatable connection with the adjusting block 1. A knob 10 is fixedly connected to one end of each second bidirectional screw 14. Two sliders 15 are symmetrically threaded on the outer surface of the second bidirectional screw 14. A locking wedge 6 is fixedly connected to one end of each slider 15. The locking wedge 6 and the locking groove 12 generate axial locking force through the inclined surface cooperation. A sliding plate 7 is fixedly connected to one side of the outer surface of each slider 15, and the sliding plate 7 slides in contact with the outer wall of the adjusting block 1. The thread helix angle of the second bidirectional screw 14 is smaller than the friction angle, which gives the second bidirectional screw 14 a self-locking capability, preventing it from shifting due to vibration or load.

[0025] Modular linkage adjustment: Multiple adjusting blocks 1 are linked together by the spline shaft 8 and the spline hole 13. Turning the handwheel 2 can drive all the first bidirectional screws 9 to rotate synchronously, so that each wire clamp 3 moves synchronously along the mounting groove 11, realizing the quick clamping or release of the wire.

[0026] Function of locking mechanism: After the number of adjusting blocks 1 is adjusted, rotate the knob 10 on the second bidirectional screw 14 to drive the two sliders 15 to move towards each other, thereby driving the locking inclined block 6 into the locking inclined groove 12.

[0027] The inclined surface of the locking wedge 6 engages with the inclined surface of the locking groove 12 of the adjacent adjusting block 1, generating radial extrusion force during axial movement, thereby pressing the adjacent adjusting blocks 1 tightly together.

[0028] The sliding plate 7 slides against the outer wall of the adjusting block 1, ensuring smooth movement of the locking ramp 6 and preventing tilting. Flexible adaptation and fixation: Adjusting the number of adjustment blocks 1 can accommodate different numbers of wires, avoiding wasted space or excessive compression.

[0029] The locking assembly ensures that each adjustment block 1 remains stably connected after adjustment, ensuring the rigidity of the overall structure, while still allowing for quick disassembly and reassembly, improving wiring flexibility and construction efficiency.
