Description

Technical Field

[0001] This invention relates to a fitting horizontal busbar trunking installation multi-directional locking bracket and its usage method. Background Technology

[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in all industries has increased rapidly. In particular, with the emergence of numerous high-rise buildings and large factory workshops, traditional cables, as power transmission conductors, can no longer meet the requirements of high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Under these circumstances, busbar trunking has emerged.

[0003] Busbar trunking is a closed metal device made of copper or aluminum busbars, used to distribute large amounts of power to various components in a distributed system. It is increasingly replacing electrical wires and cables in indoor low-voltage power transmission trunk line projects.

[0004] During installation, especially at the junction of multiple scenarios, a single-strand busbar trunking needs to be divided into multiple strands. During the division process, brackets are required for auxiliary fixation. Existing fixing brackets use lifting frames and fixing rods to fix the horizontal end of the busbar trunking.

[0005] However, simply relying on the fixing bracket to fix the horizontal end of the busbar trunking is insufficient for fixing the inclined stranding section, resulting in relatively low connection strength at the interface. Therefore, there is an urgent need for a bracket that can lock the busbar trunking in multiple directions during stranding. Summary of the Invention

[0006] The purpose of this invention is to provide a fitting horizontal busbar trunking installation multi-directional locking bracket and its usage method, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a support; The bracket surface is symmetrically provided with locking mechanisms on both the front and rear sides; The bracket surface adjustment end is symmetrically provided with a support plate that can rotate around the contact point with the bracket surface, and the locking mechanism can lock the rotation of the support plate. The support surface has symmetrically arranged external blocks on both sides to lock the external connecting rod.

[0008] Preferably, polygonal grooves are symmetrically arranged on the front and rear sides of the support surface, and polygonal blocking blocks are arranged in the polygonal grooves.

[0009] Preferably, the locking mechanism includes a first arc-shaped piece, a second arc-shaped piece, a contact block, a pressing block, and a moving block.

[0010] Preferably, contact blocks are symmetrically arranged inside the cavity of the support, and the pressing end of the contact block surface is provided with a pressing block.

[0011] Preferably, the polygonal groove is provided with an insertion slot, the insertion slot is provided with a first arc-shaped piece, and the first arc-shaped piece is provided with a moving block near the extrusion block.

[0012] Preferably, the lower end of the polygonal blocking block is provided with a locking groove, and a second arc-shaped piece is provided on the locking groove.

[0013] Preferably, extension arms are symmetrically arranged on the front and rear sides of the pallet surface, and gear blocks are symmetrically arranged on opposite sides of the extension arm surface.

[0014] Preferably, the first arc-shaped piece and the second arc-shaped piece mesh with the gear block.

[0015] Preferably, the surface of the polygonal blocking block is provided with a vertical rod that can be inserted into the insertion slot, and the outer block is provided with a reverse threaded groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When using the whole system, the lifting angle of the tray can be adjusted according to the actual situation, resulting in a better fit and a wider range of applications. In particular, the whole system is lifted at the branch interface, which has a higher connection strength than traditional brackets and is more suitable for fixing busbar trunking. 2. During installation, the external connecting rod is fixed by reverse thread groove and nut, the connection point is reinforced by bidirectional thread, and the gear block is engaged by the first arc plate and the second arc plate to further lock the support plate.

The support 1 has external blocks 6 symmetrically arranged on both sides of the surface to lock the external connecting rod.

[0021] Furthermore, polygonal grooves 2 are symmetrically arranged on the front and rear sides of the surface of the bracket 1, and polygonal blocking blocks 3 are arranged in the polygonal grooves 2; in this way, the polygonal blocking blocks 3 can be inserted into the polygonal grooves 2.

[0022] Furthermore, the locking mechanism includes a first arc-shaped piece 8, a second arc-shaped piece 12, a contact block 9, a pressing block 13, and a moving block 14; the locking mechanism locks the placement angle of the tray 4.

[0023] Furthermore, contact blocks 9 are symmetrically arranged inside the cavity of the bracket 1, and a pressing block 13 is provided on the pressing end of the surface of the contact block 9; the pressing block 13 is moved by pressing the contact block 9 through the external busbar groove.

[0024] Furthermore, the polygonal groove 2 is provided with an insertion groove 7, and the insertion groove 7 is provided with a first arc-shaped piece 8. The first arc-shaped piece 8 is provided with a moving block 14 near the pressing block 13. When the busbar groove comes into contact with and presses the contact block 9, it will drive the contact block 9 to move towards the inner wall of the bracket 1, thereby driving the pressing block 13 on the contact block 9 to press the moving block 14. Under the action of the inclined surfaces of the two, the first arc-shaped piece 8 on the surface of the pressing block 13 moves horizontally, thereby inserting into the gear block 10.

[0025] Furthermore, the lower end of the polygonal blocking block 3 is provided with a locking groove 11, and a second arc-shaped piece 12 is provided on the locking groove 11; the locking groove 11 provides an insertion space for the gear block 10, and the second arc-shaped piece 12 engages with the gear block 10 to lock it.

[0026] Furthermore, extension arms 5 are symmetrically arranged on the front and rear sides of the surface of the tray 4, and gear blocks 10 are symmetrically arranged on opposite sides of the surface of the extension arms 5; the gear blocks 10 are placed through the extension arms 5.

[0027] Furthermore, the first arc-shaped piece 8 and the second arc-shaped piece 12 mesh with the gear block 10; the meshing is used to lock the gear block 10 in multiple ranges.

[0028] Furthermore, the surface of the polygonal blocking block 3 is provided with a vertical rod 16 that can be inserted into the insertion slot 7, and the outer connecting block 6 is provided with a reverse threaded groove 15; by inserting the vertical rod 16 into the insertion slot 7, the gap is filled, reducing the influence of the external environment on the internal locking structure, and the threaded side of the external connecting rod is first connected to the bracket 1 through the reverse threaded groove 15. After connection, the bottom end of the external connecting rod is fixed by a nut, and the connection point is reinforced by bidirectional thread.

[0029] A method for using a multi-directional locking bracket for installing a fitted horizontal busbar trunking includes the following steps: Step A, Installation: First, connect the threaded side of the external connecting rod to the bracket 1 through the reverse thread groove 15. After connection, fix the bottom end of the external connecting rod with a nut, and install the external connecting rod on the designated wall according to the preset, thereby completing the installation of the bracket 1. Step B, Adjustment: Pull the polygonal blocking block 3 out of the polygonal groove 2, insert the gear block 10 on the extension arm 5 into the polygonal groove 2 according to the preset position until it is inserted to the lowest end, adjust the angle between the tray 4 and the bracket 1 according to the preset angle, and after the adjustment is completed, reinsert the polygonal blocking block 3 into the polygonal groove 2. The second arc-shaped piece 12 locks the gear block 10 through meshing, thereby locking the installation angle of the tray 4. Step C, Secondary Locking: Place the horizontal end of the busbar trunking into the cavity of the bracket 1. As the busbar trunking contacts and presses against the contact block 9, it will drive the contact block 9 to move towards the inner wall of the bracket 1, thereby driving the pressing block 13 on the contact block 9 to press against the moving block 14. Under the action of the inclined surfaces of the two, the first arc-shaped piece 8 on the surface of the pressing block 13 moves horizontally and is inserted into the gear block 10, thus completing the secondary locking. Step D: When a busbar needs to be installed on the other side, simply repeat the above steps.

[0030] The present invention provides a multi-directional locking bracket for mounting horizontal busbar trunking and its method of use, which has the following advantages: 1. When using the whole system, the lifting angle of the support plate 4 can be adjusted according to the actual situation, resulting in a better fit and a wider range of applications. In particular, the whole system is lifted at the branch interface, which makes its connection strength higher than that of traditional brackets and more suitable for fixing busbar trunking. 2. During installation, the external connecting rod is fixed by the reverse thread groove 15 and the nut, the connection point is reinforced by the bidirectional thread, and the gear block 10 is engaged by the first arc-shaped piece 8 and the second arc-shaped piece 12 to further lock the support plate 4.
