Description

Technical Field

[0001] This utility model relates to the technical field of electrical equipment installation accessories, specifically an adjustable distance fixing bracket for busbar trunking. Background Technology

[0002] Busbar trunking, as a key component for power transmission, is widely used in power distribution systems in buildings, industrial plants, and other settings. Existing busbar trunking mounting brackets are mostly integrated structures, and the spacing between their crossarms and wall fasteners cannot be flexibly adjusted.

[0003] In actual installation, when the spacing of the busbar trunking needs to be fine-tuned, or when there are differences in power distribution requirements in different areas, traditional fixed brackets need to be replaced with products of different specifications to be compatible, which not only increases construction costs but also extends the installation period. At the same time, some adjustable brackets have problems such as insufficient connection stability and cumbersome adjustment operations, making it difficult to meet the requirements of efficient and safe installation. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing busbar trunking fixing brackets, such as non-adjustable spacing, poor adaptability, low installation efficiency, and insufficient stability, by providing an adjustable spacing fixing bracket for busbar trunking. This invention enables flexible spacing adjustment, convenient installation, and reliable fixing.

[0005] This utility model is achieved through the following technical solution: An adjustable distance fixing bracket for a busbar trunking includes a busbar trunking, steel sliding rails, a steel crossarm, a first bolt, a second bolt, and a third bolt. Two steel sliding rails are provided, one on the left and one on the right, with a second bolt connecting to both ends of each rail. The two ends of the steel crossarm are respectively limited and slidably secured to the two steel sliding rails, and the two ends of the crossarm are threadedly connected to the first bolt. The threaded end of the first bolt passes through the crossarm and abuts against the steel sliding rail. The busbar trunking is supported on the steel crossarm, and the two sides of the busbar trunking are connected to the third bolt, which is threadedly fastened to the steel crossarm.

[0006] Furthermore, track baffles are fixedly connected to both ends of the steel sliding track.

[0007] Furthermore, the track baffles are made of sheet steel.

[0008] Furthermore, the steel sliding track is a long strip structure, which includes a base plate, on which a T-shaped rail is fixed. A second bolt is connected through both ends of the base plate, and the track baffle is fixed to both ends of the T-shaped rail by welding or bolting.

[0009] Furthermore, the bottom of both ends of the steel crossbeam are respectively provided with T-slots that match the T-rails, and the T-slots are slidably locked onto the T-rails.

[0010] Furthermore, each end of the steel crossbeam is threaded with two first bolts.

[0011] Furthermore, the top of the steel crossarm is provided with a placement groove that matches the busbar trough. The busbar trough is placed in the placement groove, and the third bolt passes through the wall of the busbar trough and is threadedly connected to the steel crossarm.

[0012] Furthermore, the second bolt is an M8 bolt.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: 1) Flexible spacing adjustment: The steel crossarm can slide freely along the steel sliding track and be locked in place by the first bolt. The spacing can be precisely adjusted according to the installation requirements of the busbar trunking, adapting to the layout requirements of different power distribution scenarios, without the need to replace the support body.

[0014] 2) High installation efficiency: Most components are connected by bolts, making disassembly and assembly easy. Adjustment can be completed without professional tools, greatly shortening the construction cycle.

[0015] 3) Strong structural stability: All load-bearing components are made of steel, which has high strength and load-bearing capacity. Combined with the wall fixing method of M8 bolts and the limiting design of the track baffles at both ends, it ensures that there is no risk of loosening or falling off after the busbar is installed, thus improving the operational safety of the power distribution system.

[0016] 4) Wide adaptability: It can be flexibly adjusted according to the specifications and installation spacing requirements of the bus trunking, and is suitable for power distribution installation of different models of bus trunking and various building and industrial scenarios.

[0022] To enable those skilled in the art to better understand this utility model, the present utility model will be further described clearly and completely below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] like Figures 1 to 3 As shown, this embodiment provides an adjustable distance fixing bracket for busbar trunking, including busbar trunking 1, steel sliding rail 2, steel crossarm 3, first bolt 5, second bolt 6 and third bolt 7.

[0024] The steel sliding track 2 consists of two sections, left and right, with a second bolt 6 connecting both ends of each section. The steel sliding track 2 is a long, narrow structure, including a base plate on which a T-shaped rail is fixed. The second bolts 6 connect both ends of the base plate. The steel sliding track 2 is fixed to the wall using M8 bolts 6 to ensure a secure connection between the steel sliding track 2 and the wall.

[0025] The two ends of the steel sliding rail 2 are fixedly connected with rail baffles 4. The rail baffles 4 are sheet-like steel structures and are fixedly connected to the two ends of the T-shaped rail of the steel sliding rail 2 by welding or bolting. The rail baffles 4 are used to limit the sliding stroke of the steel crossarm 3 on the steel sliding rail 2 and prevent the steel crossarm 3 from falling off the two ends of the steel sliding rail 2.

[0026] The two ends of the steel crossbeam 3 are respectively limited and slidably locked on two steel sliding rails 2; specifically, the bottom of the two ends of the steel crossbeam 3 are respectively provided with T-shaped grooves that match the T-shaped rails, and the T-shaped grooves are slidably locked on the T-shaped rails.

[0027] The steel crossarm 3 has two threaded bolts 5 at each end. The threaded end of the first bolt 5 passes through the T-slot of the steel crossarm 3 and abuts against the T-rail of the steel sliding track 2. Specifically, each end of the steel crossarm 3 is threaded with two first bolts 5. When the first bolt 5 is rotated to abut against and lock the T-rail, the steel crossarm 3 is fixed on the steel sliding track 2 and cannot slide on the steel sliding track 2. When the first bolt 5 is rotated to loosen it, the steel crossarm 3 can be pushed to slide along the length of the steel sliding track 2 to achieve spacing adjustment.

[0028] The busbar trough 1 is supported on the steel crossarm 3. The two sides of the busbar trough 1 are connected by third bolts 7, which are threadedly fastened to the steel crossarm 3. Specifically, the top of the steel crossarm 3 is provided with a placement groove that matches the busbar trough 1, which is used to support and position the busbar trough 1. The busbar trough 1 is placed in the placement groove, and the third bolts 7 penetrate the groove wall of the busbar trough 1 and are threadedly connected to the steel crossarm 3, fixing the busbar trough 1 to the steel crossarm 3 and preventing its displacement.

[0029] The construction steps for the adjustable distance fixing bracket for the busbar trunking described in this embodiment are as follows: 1) Installation preparation: According to the installation plan of busbar trunking 1, determine the wall fixing position of steel sliding rail 2 and ensure that the installation direction of the rail is consistent with the layout direction of busbar trunking 1.

[0030] 2) Track fixing: Attach the steel sliding track 2 to the preset position on the wall and tighten it evenly with M8 second bolts 6 to firmly connect the steel sliding track 2 to the wall. The number of second bolts 6 is set according to the length of the steel sliding track 2 and the load-bearing requirements (usually no less than 2 per meter).

[0031] 3) Crossarm installation and adjustment: Slide the steel crossarm 3 onto the steel sliding rail 2. According to the installation spacing requirements of the busbar 1, push the steel crossarm 3 along the steel sliding rail 2 to the target position, tighten the first bolt 5, so that the steel crossarm 3 and the steel sliding rail 2 are tightly fixed to avoid displacement.

[0032] 4) Limiting installation: Fix the rail baffles 4 at both ends of the steel sliding rail 2 to ensure that the rail baffles 4 fit tightly with the end face of the steel sliding rail 2, thereby achieving the sliding limit of the steel crossbeam 3.

[0033] 5) Busbar trunking fixing: Place the busbar trunking 1 in the placement slot of the steel crossarm 3, align the bolt holes of the busbar trunking and the steel crossarm 3, insert the third bolt 7 and tighten it to complete the fixing and installation of the busbar trunking 1.

[0034] 6) Adjustment operation: If the spacing of busbar 1 needs to be adjusted later, simply loosen the first bolt 5, push the steel crossarm 3 to the new position and then tighten it again. The operation is simple and does not affect the overall structural stability.

[0035] The embodiments described above only illustrate the preferred implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
