Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, and in particular to a building control cable protection device. Background Technology

[0002] In modern intelligent building power distribution systems, the large-scale laying of control cables presents two main characteristics: first, centralized wiring of multiple cables at a single point (such as the need to lay 6-8 cables in parallel at the control box outlet of a building automation system); and second, the diversity of installation surfaces caused by complex building structures (concrete walls, steel beams, overhead pipelines, etc.).

[0003] Current cable fixing technologies suffer from the following typical defects: 1. Traditional single-point fixing clips, as shown in patent CN202972207U, only support the fixing of a single cable. In actual engineering, a linear stacking pattern of "1 cable = 1 clip = 1 hole" must be adopted, which not only increases the wall damage rate but also leads to low construction efficiency; 2. Existing technologies rely excessively on rigid fixing methods, and expansion bolt wall fixing schemes are not applicable to areas where drilling is prohibited. To address these defects, we propose a building control cable protection device. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a building control cable protection device, including a buckle, which is composed of a base plate 10 and a buckle assembly disposed on one side of the base plate 10. The buckle assembly includes a semi-circular first protective ring 11 fixedly installed on the left side of the base plate 10, a second protective ring 12 rotatably connected to the left side of the base plate 10 via a rotating shaft, and a locking component disposed at the closed end of the first protective ring 11 and the second protective ring 12. The first protective ring 11 is a fixed semi-ring, providing a cable bearing base. Anti-slip rubber pads are fixedly installed on the inner walls of both the first protective ring 11 and the second protective ring 12. The second protective ring 12 can be opened and closed from 0 to 90° via a rotating shaft. After closing, it forms a complete protective ring with the first protective ring 11. The inner diameter of this ring is adapted to the outer diameter of the cable.

[0030] The locking component includes a locking plate 20 fixed to the closed ends of the first protective ring 11 and the second protective ring 12 respectively, a threaded hole opened on the surface of the locking plate 20, and a locking bolt 21 threaded into the threaded hole. The locking plate 20 is vertically welded to the ends of the first protective ring 11 and the second protective ring 12 respectively, providing a locking plane for the locking bolt 21. The locking bolt 21 is screwed into the threaded hole to generate pressure, so that the first protective ring 11 and the second protective ring 12 tightly close and fix the cable.

[0031] The substrate 10 is provided with a self-assembly structure, which includes a circular groove 30 formed on the upper left side of the substrate 10, a circular plate 31 fixed to the lower surface of the substrate 10 and adapted to the circular groove 30, a hexagonal recess 32 formed on the inner wall of the circular groove 30, and a through hole penetrating the bottom surface of the recess 32 and the surface of the circular plate 31. The circular groove 30 and the circular plate 31 are nested together to achieve positioning of the substrate 10.

[0032] A hexagonal nut 33 is embedded in the recess 32. The depth of the recess 32 matches the thickness of the hexagonal nut 33. The inner wall of the recess 32 and the outer wall of the hexagonal nut 33 form an anti-rotation fit. The hexagonal nut 33 is threadedly connected to a first mounting bolt 34. The recess 32 restricts the rotation of the hexagonal nut 33, forming an "embedded wrench effect". The first mounting bolt 34 is screwed into the hexagonal nut 33, generating a vertical pulling force that can lock the two substrates 10.

[0033] A circular pad 40 is detachably provided on the right side of the circular plate 31. The circular pad 40 has a through hole in the center. The through hole and the through hole are coaxial and have the same diameter. In mode A, the circular groove 30 of the substrate 10 and the circular plate 31 engage with each other. With the help of the hexagonal anti-rotation groove 32 and the hexagonal nut 33, "1+N" cascading expansion can be achieved. When 8 cables are fixed in parallel, the amount of drilling is reduced and the installation efficiency is improved. The circular pad 40 fills the gap between the circular plate 31 on the end substrate 10 and the wall, ensuring the anchoring stability of mode A.

[0034] A limiting block 60 is fixed at the lower end of the circular plate 31. A limiting groove 61 is opened on the inner wall of the circular groove 30. The limiting block 60 is a rectangular protrusion, and the corresponding limiting groove 61 is a rectangular groove. The limiting block 60 and the limiting groove 61 are in clearance fit. The rectangular concave-convex fit between the limiting block 60 and the limiting groove 61 prevents the substrate 10 from rotating relative to each other during cascading.

[0035] The device also includes a mounting structure, which includes a U-shaped frame 50, bolt holes on the surface of the U-shaped frame 50, and a second mounting bolt 51 inserted into the bolt holes. When encountering areas where expansion bolts cannot be used, a steel cable is installed at a drilling location. The steel cable passes through a no-drill area, the U-shaped frame 50 is strung with the steel cable, and the hexagonal nut 33 is transferred from the sink 32 to the U-shaped frame 50. After the second mounting bolt 51 is tightened, a flexible connection of "base plate 10-U-shaped frame 50-steel cable" is formed. Through the flexible connection between the U-shaped frame 50 and the steel cable, zero-structural-damage installation is achieved in the no-drill area.

[0036] Specifically, the working principle and operation method of this utility model are as follows:

[0037] 1. Open the buckle: Loosen the locking bolt (21) counterclockwise and rotate the second protective ring (12) outward around the axis to the open state of 90°.

[0038] Cable placement: Place the cable into the arc-shaped groove of the first protective ring 11.

[0039] Close and lock: Rotate the second protective ring (12) to the closed position so that the two rings form a complete circle to wrap the cable. Tighten the locking bolt (21) clockwise and fix the cable by the pressure generated by the locking plates (20) on both sides.

[0040] II. Modular Cascading ("1+N" Parallel Fixed)

[0041] Preparation of the first substrate 10: Insert the hexagonal nut (33) into the hexagonal groove (32) of the first substrate (10).

[0042] Nested cascaded substrate 10: Insert the circular plate (31) of the second substrate 10 into the circular groove 30 of the first substrate 10, align the rectangular limiting block (60) at the bottom of the circular plate (31) with the limiting groove 61 on the inner wall of the circular groove 30, and ensure that the limiting block 60 slides into the limiting groove 61.

[0043] Bolt locking cascade unit: The first assembly bolt (34) is screwed into the hexagonal nut (33) in the hexagonal groove 32 through the through hole of the circular plate (31) to lock the two base plates 10.

[0044] Repeat steps 1-3 to expand the N-level substrate as needed.

[0045] End reinforcement (mode A anchoring): A circular pad (40) is installed on the right side of the circular plate (31) of the last stage substrate to fill the gap with the wall.

[0046] Use expansion bolts to pass through the following holes in sequence: the first-stage substrate 10 through hole → the wall hole → the last-stage substrate 10 through hole → the circular pad (40) through hole, and tighten the expansion bolts to complete the wall fixation.

[0047] Note: Only two anchor points are needed at the beginning and end for the 8 parallel cables, eliminating the need for 10 drilling holes per substrate.

[0048] III. Suspension Plan for Drill-Restricted Areas (Mode B Flexible Installation)

[0049] Steel rope deployment: Fix both ends of the steel rope in the drillable area, so that the steel rope crosses the no-drill area and is straightened.

[0050] U-shaped frame mounting: Hang the U-shaped frame (50) across the steel rope with the U-shaped opening facing down.

[0051] Nut transfer: Take out the hexagonal nut (33) from the hexagonal recess (32) on the substrate 10 and place it in the preset position on the right side of the U-shaped bracket (50).

[0052] Bolt locking suspension point: Pass the second assembly bolt (51) through the bolt hole of the U-shaped frame (50) and screw it into the hexagonal nut (33) after transfer. After tightening, a flexible connection of "base plate 10-U-shaped frame 50-steel rope" is formed.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
