Description

Technical Field

[0001] This utility model relates to the field of busbar trunking construction technology, specifically a convenient and compact busbar trunking system. Background Technology

[0002] A compact busbar trunking system is a power transmission device consisting of conductive copper or aluminum busbars encased in an insulating material and installed within a metal casing. It is primarily used in low-voltage power distribution systems to centrally transmit and distribute power. Compact busbar trunking systems are typically used in conjunction with plug-in boxes to distribute and branch power outputs. By connecting to the busbar trunking, it transmits power from the main line to various electrical devices or branch circuits.

[0003] Traditional compact busbar trunking and junction boxes are usually fixed with bolts. During installation, wrenches or other tools are usually needed for fixing or disassembling. The operation is complicated and time-consuming. When installing or disassembling for maintenance in special environments, such as high-altitude work environments, technicians need to wear safety equipment, and their hand operation range is limited. Using wrenches and other tools is even more inconvenient, which seriously affects the work efficiency of technicians. Utility Model Content

[0004] The purpose of this utility model is to provide a convenient and compact busbar trunking system, which aims to solve the problem in the prior art where technicians have limited operating range and find it inconvenient to use tools to install and disassemble the plug-in box in special environments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a convenient and compact busbar trunking, comprising a busbar trunking body and a plug-in box, wherein the plug-in box is provided with a clamping mechanism for quickly installing the plug-in box onto the busbar trunking body, and the busbar trunking body is provided with an interlocking connection structure that cooperates with the clamping mechanism. The clamping mechanism includes mounting boxes symmetrically arranged on the upper and lower sides of the plug-in box, and two connecting rods with bent front ends are hinged in the mounting boxes, with a tension spring between the two connecting rods. The interlocking connection structure includes T-shaped seats symmetrically arranged on the upper and lower sides of the busbar trunking body, and an arc-shaped protrusion is fixedly connected to the front end of the T-shaped seat.

[0006] Preferably, the clamping mechanism further includes pull rods symmetrically arranged inside the mounting box, each pull rod being hinged to a connecting rod, a spring being coaxially sleeved on each pull rod, and a handle being installed at one end of each pull rod after it extends out of the mounting box.

[0007] Preferably, the mounting box is detachably mounted on the plug-in box by bolts.

[0008] Preferably, the front end of the connecting rod is rotatably equipped with a roller.

[0009] Preferably, the plug-in box is provided with a shock-absorbing plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. In use, this utility model is achieved by hinged two connecting rods inside the mounting box and pulling the two connecting rods with a tension spring to close their front ends. When the T-shaped seat is inserted between the two connecting rods, the bent structure at the front end of the T-shaped seat engages with the arc-shaped protrusion at the front end of the T-shaped seat to achieve quick connection.

[0012] 2. In use, this utility model features two pull rods hinged to the connecting rods inside the mounting box, with springs fitted on the pull rods. The spring force pushes the pull rods against the connecting rods, enhancing the closing force at the ends of the two connecting rods. This strengthens the engagement with the T-shaped seat and maintains the stability of the plug-in box on the busbar trunking. When the plug-in box needs to be disassembled, technicians can pull a handle to move the pull rod backward. As the pull rod moves backward, it causes the two connecting rods to flip away from each other, thus losing their engagement with the T-shaped seat. This allows the plug-in box to be directly removed from the busbar trunking, making disassembly quick and easy, and reducing the difficulty of disassembly. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0020] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0021] like Figure 1-3 As shown, a convenient and compact busbar trunking includes a busbar trunking body 1 and a plug-in box 2. The plug-in box 2 is provided with a clamping mechanism for quickly installing the plug-in box 2 onto the busbar trunking body 1. The busbar trunking body 1 is provided with an interlocking connection structure that cooperates with the clamping mechanism. The clamping mechanism includes mounting boxes 5 symmetrically arranged on the upper and lower sides of the plug-in box 2. Two connecting rods 6 with bent front ends are hinged in the mounting boxes 5. A tension spring 7 is provided between the two connecting rods 6. The interlocking connection structure includes T-shaped seats 4 symmetrically arranged on the upper and lower sides of the busbar trunking body 1. An arc-shaped protrusion is fixedly connected to the front end of the T-shaped seat 4.

[0022] In this embodiment, two connecting rods 6 are hinged in the mounting box 5, and the front ends of the two connecting rods 6 are closed by the tension spring 7. When the T-shaped seat 4 is inserted between the two connecting rods 6, the bent structure at the front end of the T-shaped seat 4 engages with the arc-shaped protrusion at the front end of the T-shaped seat 4 to achieve quick connection.

[0023] like Figure 3 As shown, the clamping mechanism also includes pull rods 8 symmetrically arranged inside the mounting box 5. Each pull rod 8 is hinged to a connecting rod 6. A spring 9 is coaxially sleeved on the pull rod 8. A handle 10 is installed on one end of the pull rod 8 after it extends out of the mounting box 5.

[0024] In this embodiment, the spring 9 sleeved on the pull rod 8 pushes the pull rod 8 against the connecting rod 6 through elastic force, enhancing the closure of the ends of the two connecting rods 6, thereby enhancing the engagement with the T-shaped seat 4 and maintaining the stability of the plug box 2 on the busbar trunking body 1. When it is necessary to disassemble the plug box 2, a handle 10 can be pulled to move the pull rod 8 backward, thereby causing the two connecting rods 6 to flip away from each other, thus losing the engagement with the T-shaped seat 4. As a result, the plug box 2 can be directly removed from the busbar trunking body 1, which is convenient, quick, and reduces the difficulty of disassembly.

[0025] like Figure 2As shown, the mounting box 5 is detachably mounted on the plug-in box 2 by bolts 11.

[0026] In this embodiment, the mounting box 5 is installed onto the plug box 2 by means of bolts 11. When the mounting box 5 needs maintenance, it can be disassembled and maintained by removing the bolts 11.

[0027] like Figure 3 As shown, a roller 12 is rotatably mounted on the front end of the connecting rod 6.

[0028] In this embodiment, by setting rollers 12, the connecting rod 6 and the arc-shaped protrusion at the front end of the T-shaped seat 4 are smoothly intersected, reducing the resistance during insertion.

[0029] like Figure 2 As shown, the plug-in box 2 is equipped with a shock-absorbing plate 3.

[0030] In this embodiment, the impact force when the plug-in box 2 is installed on the busbar trunking body 1 is reduced by setting the shock-absorbing plate 3.

[0031] Working principle: In use, technicians can hold the plug-in box 2 and align the mounting box 5 on the plug-in box 2 with the T-shaped seat 4 on the busbar trunking body 1. Then, the plug-in box 2 is fastened onto the busbar trunking body 1. The two connecting rods 6 on the mounting box 5 are closed at their front ends by the tension spring 7. The arc-shaped protrusion at the front end of the T-shaped seat 4 passes through the rollers 12 at the front ends of the two connecting rods 6 and engages and fixes them. The spring 9 sleeved on the pull rod 8 pushes the pull rod 8 against the connecting rod 6 through elastic force, which enhances the closing force at the ends of the two connecting rods 6, thereby enhancing the engagement with the T-shaped seat 4 and maintaining the stability of the plug-in box 2 on the busbar trunking body 1. When it is necessary to disassemble the plug-in box, the technician can pull a handle 10 to pull the pull rod 8 backward. When the pull rod 8 moves backward, it causes the two connecting rods 6 to flip away from each other, thereby losing the engagement with the T-shaped seat 4. Thus, the plug-in box 2 can be directly removed from the busbar trunking body 1, which is convenient, quick and easy and reduces the difficulty of disassembly.
