Description

Technical Field

[0001] This utility model relates to a busbar trunking cover plate fixing structure. Background Technology

[0002] Busbar trunking is widely used in power transmission and distribution systems for centralized transmission of electrical energy.

[0003] Most existing busbar trunking covers rely on simple bolts for direct connection. During installation, each bolt must be precisely aligned and tightened, which is time-consuming and labor-intensive. This is especially true for long busbar trunking sections, where the workload is enormous, reducing installation efficiency and increasing construction costs.

[0004] Once the busbar trunking needs adjustment or repair, disassembling the cover plate is very inconvenient and can easily damage the fasteners and cover plate, which is not conducive to subsequent reuse and maintenance.

[0005] Therefore, a busbar trunking cover fixing structure is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a busbar trunking cover fixing structure to solve the problem of time-consuming and labor-intensive installation of existing busbar trunking covers mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a busbar trunking cover plate fixing structure, comprising a busbar trunking body and cover plates located at the upper and lower ends of the busbar trunking body, wherein end plates are provided on both sides of the busbar trunking body, and the end plates are connected to the cover plates by fixing components around their perimeter.

[0008] The cover plate moves along the end plates on both sides of the busbar trunking body to the fixing component, and the fixing component connects and locks the cover plate to the end plates.

[0009] Preferably, the fixing component includes multiple sets of positioning grooves opened around the end plate, and fixing bolts are provided at the positioning grooves. The lower part of the fixing bolts is connected to the locking bolts through a limiting plate.

[0010] Preferably, the lower part of the positioning groove has a channel for the movement of the locking bolt, and the inner diameter of the channel is smaller than the outer diameter of the limiting plate.

[0011] Preferably, a reset spring is provided inside the positioning groove, and the reset spring is located at the lower part of the limiting plate, so that the limiting plate can move elastically inside the positioning groove by means of the reset spring.

[0012] Preferably, the upper part of the fixing bolt is inclined, and the angle between the inclined surface and the horizontal plane is 35°.

[0013] Preferably, the top surface of the fixing bolt is provided with a rotating groove for the screwdriver to rotate, so that the screwdriver can rotate through the rotating groove connected to the fixing bolt.

[0014] Preferably, the lower outer periphery of the locking bolt is provided with a insertion groove for the cover plate to be inserted.

[0015] Preferably, the cover plate is provided with slide rails on both sides that mate with the upper and lower ends of the end plate.

[0016] The slide rail has slots on both sides for the movement of the locking bolt. The spacing at the end of the slots matches the insertion slot so that the slide rail is connected to the outer periphery of the locking bolt through the slots.

[0017] The cover plate has positioning holes around its perimeter for locking bolt insertion.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This utility model uses a fixing assembly set around the end plate of the busbar trunking body. By utilizing the synergistic effect of components such as positioning grooves, fixing bolts, locking bolts, and return springs, the cover plate and the end plate are tightly connected and locked. This provides the cover plate with multi-point, uniform, and stable fixing force. Compared with the traditional bolt fixing method, which involves a huge amount of work, this fixing structure can effectively reduce the cumbersome steps in the installation process, greatly shorten the installation time, improve the overall installation efficiency, and reduce the construction cost.

[0020] The cover plate can be moved along the end plates on both sides of the busbar trunking to the fixing component, eliminating the need for precise alignment and tightening of each bolt individually. This simplifies the installation process, saves installation time, significantly reduces workload, improves installation efficiency, and reduces construction costs. Meanwhile, the beveled design on the upper part of the fixing bolt and the structure where the screwdriver drives the fixing bolt through the rotating groove allow the locking bolt to move and lock smoothly, further reducing the difficulty of the installation operation and making the installation process more effortless and convenient.

[0021] When disassembling the cover plate, the operation can be reversed. With the help of the elasticity of the return spring, the locking bolt can be quickly reset and unlocked, and the cover plate can be easily slid out along the slide rail. There is no need to remove a large number of bolts, which greatly improves the efficiency of disassembly. It is convenient for subsequent adjustment, maintenance or replacement of the cover plate of the bus trunking. Moreover, the fixing components can be reused, reducing maintenance costs, extending the service life of the bus trunking, and improving its economy and practicality. Attached Figure Description

[0028] To address the problem of time-consuming and labor-intensive installation of existing busbar trunking covers, this utility model provides a busbar trunking cover fixing structure. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Please see Figure 1-5 This utility model provides a busbar trunking cover fixing structure, including a busbar trunking body 1 and cover plates 2 located at the upper and lower ends of the busbar trunking body 1. End plates 11 are provided on both sides of the busbar trunking body 1. The end plates 11 are connected to the cover plates 2 around their perimeter by fixing components 3. Each fixing component 3 includes multiple sets of positioning grooves 31 around the end plates 11. Fixing bolts 32 are provided at the positioning grooves 31, and the lower part of each fixing bolt 32 is connected to a locking bolt 33 via a limiting plate 35. A channel 311 for the movement of the locking bolt 33 is provided in the lower part of the positioning groove 31, and the inner diameter of the channel 311 is smaller than the outer diameter of the limiting plate 35. A return spring 34 is provided inside the positioning groove 31, and the return spring 34 is located below the limiting plate 35, allowing the limiting plate 35 to move elastically within the positioning groove 31 via the return spring 34. The upper part of the fixing bolt 32 is inclined, and the angle between the inclined surface and the horizontal plane is 35°. The top surface of the fixing bolt 32 has a rotating groove 321 for the screwdriver to rotate, so that the screwdriver can rotate through the rotating groove 321 connected to the fixing bolt 32. The lower outer periphery of the locking bolt 33 has an insertion groove 331 for the cover plate 2 to be inserted.

[0030] The cover plate 2 is provided with slide rails 21 on both sides that cooperate with the upper and lower ends of the end plate 11.

[0031] The slide rail 21 has slots 22 on both sides for the movement of the locking bolt 33. The spacing at the end of the slots 22 matches the insertion slot 331 so that the slide rail 21 is connected to the outer periphery of the locking bolt 33 through the slots 22. The cover plate 2 has positioning holes 23 around its surface for the locking bolt 33 to be inserted.

[0032] The cover plate 2 moves along the end plates 11 on both sides of the busbar trunking body 1 to the fixing component 3, and the fixing component 3 connects and locks the cover plate 2 and the end plates 11.

[0033] The working principle of the busbar trunking cover fixing structure provided by this utility model is as follows:

[0034] First, place the cover plate at the upper and lower ends of the busbar trunking body, and then move the cover plate along the end plates on both sides of the busbar trunking body. The slide rails on both sides of the cover plate engage with the upper and lower ends of the end plates, and slide along the end plates until the cover plate moves to the fixed assembly.

[0035] When the cover plate moves to the position of the fixed component, the cover plate moves along the upper inclined surface of the fixing bolt. The fixing bolt is forced to move through the limiting plate 35 to press the return spring located inside the positioning groove until the fixing bolt is forced to move down and is stored in the positioning groove.

[0036] Once the positioning hole of the cover plate moves to the position of the fixing bolt at the tail end, the return spring elastically extends, pushing the fixing bolt out and inserting it into the positioning hole.

[0037] At the same time, the insertion slots on both sides of the outer periphery of the locking bolt are rotated and fitted into the inner side wall of the slot, and the slide rail is connected to the outer periphery of the locking bolt through the slot, thereby locking the connection between the cover plate and the end plate.

[0038] Then insert the screwdriver into the rotating slot and rotate the retaining bolt 90 degrees to rotate its inclined surface, preventing the cover plate from slipping between the retaining bolt and the inclined surface.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
