Description

Technical Field

[0001] This utility model relates to a cable tray connection structure. Background Technology

[0002] With the continuous development of power systems, cable trays, as a structure used for laying cables, have been widely used in power engineering.

[0003] Traditional cable tray connections typically use bolts. When cable trays are exposed to vibration, such as in industrial plants or near large machinery, the vibration can cause the connection between the connectors and the tray to gradually loosen. Vibration subjectes bolts and rivets to repeated alternating stresses, leading to fatigue and ultimately loosening of the connection. This can easily result in unstable connections.

[0004] Therefore, a cable tray connection structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a cable tray connection structure to solve the problem mentioned in the background art that the traditional cable tray connection method usually uses bolt connection. When the cable tray is in a vibration environment, the vibration will cause the bolts or rivets and other fasteners to be subjected to alternating stress repeatedly, thereby generating fatigue and easily causing unstable connection.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cable tray connection structure, including a connecting support plate located at the connection point of two sets of cable trays, wherein two sets of connecting components are provided on both sides of the connecting support plate, and the connecting support plate connects the two sets of cable trays through the connecting components.

[0007] Preferably, the connecting component includes a plug-in base, a limiting plate is provided at the bottom of the plug-in base, connecting grooves are provided on both sides of the plug-in base, and a fixing plate is connected in the connecting groove.

[0008] Preferably, a limiting groove is provided on the side of the connecting groove, and limiting stops that cooperate with the limiting groove are provided on both sides of the fixing plate.

[0009] Preferably, the socket is provided with a positioning bolt inside, and a retaining ring is provided on the upper part of the positioning bolt.

[0010] Preferably, a support plate is provided on the inner side of the fixed position, and a channel for cooperating with the positioning bolt is opened between the two sets of support plates, and the inner diameter of the channel is smaller than the inner diameter of the retaining ring.

[0011] Preferably, the upper part of the fixing plate is provided with a concave groove that mates with the positioning bolt, so that the fixing plate can rotate and fit against the outer periphery of the positioning bolt through the concave groove.

[0012] Preferably, a return spring is provided at the lower part of the plug-in seat and the return spring is located on the outer periphery of the positioning bolt.

[0013] Preferably, the plug-in seat is provided with a threaded seat that mates with the positioning bolt at the lower part of the positioning bolt, so that the positioning bolt can move inside the plug-in seat through the threaded seat.

[0014] Preferably, two sets of positioning holes for plug-in connection are provided on both sides of the connection between the two sets of cable trays. The inner wall of the cable tray is provided with an inner groove that cooperates with the limiting plate at the positioning hole, so that the limiting plate is connected to the inner wall of the cable tray through the inner groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Compared to traditional bolted connections, this invention effectively avoids loosening caused by vibration. The connecting components on both sides of the support plate can better distribute stress, making the connection more stable.

[0017] The connector, limiting plate, and fixing plate in the connection assembly work together to form a stable connection structure. The limiting plate engages with the inner groove on the inner wall of the cable tray to further enhance the stability of the connection and prevent displacement or loosening at the connection point.

[0018] Compared to traditional bolted connections, this connection structure eliminates the need for numerous bolts and complex tightening procedures. By simply tightening the positioning bolts, cable trays can be quickly and easily connected and secured, significantly simplifying the installation process and improving efficiency.

This invention provides a cable tray connection structure. The technical solutions of this invention 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 invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0028] Please see Figure 1-7 This utility model provides a cable tray connection structure, including a connecting support plate 1 located at the connection of two sets of cable trays 3. Two sets of connecting components 2 are provided on both sides of the connecting support plate 1, and the connecting support plate 1 connects the two sets of cable trays 3 through the connecting components 2.

[0029] The connecting assembly 2 includes a plug-in base 201. A limiting plate 202 is provided at the bottom of the plug-in base 201. Connecting grooves 203 are formed on both sides of the plug-in base 201, and a fixing plate 204 is connected within the connecting grooves 203. A limiting slide groove 2031 is provided beside the connecting groove 203, and limiting stops 2041 that cooperate with the limiting slide groove 2031 are provided on both sides of the fixing plate 204. A positioning bolt 205 is provided inside the plug-in base 201, and a retaining ring 2051 is provided on the upper part of the positioning bolt 205. A support plate 2042 is provided inside the fixing position, and a channel 2043 that cooperates with the positioning bolt 205 is formed between the two sets of support plates 2042, and the inner diameter of the channel 2043 is smaller than the inner diameter of the retaining ring 2051. Each of the fixed plates 204 has a recessed groove 2044 on its upper part that mates with the positioning bolt 205, allowing the fixed plate 204 to rotate and fit against the outer periphery of the positioning bolt 205 through the recessed groove 2044. A return spring 207 is provided on the lower part of the plug-in seat 201 below the positioning bolt 205, and the return spring 207 is located on the outer periphery of the positioning bolt 205. A threaded seat 206 is provided on the lower part of the plug-in seat 201 below the positioning bolt 205, allowing the positioning bolt 205 to move within the plug-in seat 201 through the threaded seat 206.

[0030] Two sets of positioning holes 301 for connecting the plug-in base 201 are provided on both sides of the connection of the two sets of cable trays 3. The inner side wall of the cable tray 3 is provided with an inner groove 302 that cooperates with the limiting plate 202 at the positioning hole 301, so that the limiting plate 202 is connected to the inner side wall of the cable tray 3 through the inner groove 302.

[0031] The working principle of the cable tray connection structure provided by this utility model is as follows: During installation, the connecting support plate 1 is placed at the connection of the two sets of cable trays 3, so that the through holes on both sides of the connecting support plate 1 are aligned with the positioning holes 301 of the two sets of cable trays 3 respectively.

[0032] Insert the plug-in socket 201 in the connecting assembly 2 into the positioning hole 301 of the cable tray 3, and at the same time make the limiting plate 202 cooperate with the inner groove 302 of the inner side wall of the cable tray 3 to ensure that the plug-in socket 201 is firmly installed on the cable tray 3.

[0033] Rotate the positioning bolt 205 so that it is screwed into the threaded seat 206 through the channel 2043 of the fixing plate 204. The positioning bolt 205 presses down on the support plate 2042 of the fixing plate 204 through the retaining ring 2051. The fixing plate 204 is subjected to force and deflects inside the limiting groove 2031 through the limiting stop bar. At the same time, the support plate 2042 compresses the return spring 207. When the retaining ring 2051 drives the fixing plate 204 to be compressed to the bottom, the support plate 2042 moves to the return spring 207. At this time, the fixing plate 204 deflects at a certain degree. The concave groove 2044 at the top of the fixing plate 204 engages with the outer periphery of the positioning bolt 205. The return spring 207 contacts the upper bottom surface of the fixing plate 204. Then, the positioning bolt 205 is continuously rotated. The positioning bolt 205 and the fixing plate 204 gradually move down to the bottom of the connecting groove 203. The fixing plate 204 engages with the side of the connecting support plate 1. The connecting support plate 1 and the cable tray 3 are tightly connected by the fixing plate 204 and the limiting plate 202.

[0034] At the same time, the elastic force generated by the return spring 207 acts on the side of the positioning bolt 205 through the fixing plate 204, tightly connecting the positioning bolt 205 and the threaded seat 206.

[0035] 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.
