Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and specifically to a cable tray that can be telescopically adjusted. Background Technology

[0002] Cable trays are classified into trough type, tray type, ladder type, and mesh type structures. They are composed of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building (structure) and pipe gallery supports. They should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors are also classified as such.

[0003] The existing cable tray specifications are relatively fixed, which makes it impossible to adjust the shape of the cable tray according to the usage situation, thus causing certain impacts during use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a telescopic and adjustable cable tray. This solves the problem that the fixed specifications of existing cable trays prevent users from adjusting their tray shape according to the usage conditions, thus causing certain problems during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A telescopic and adjustable cable tray includes a cable tray body, the cable tray body includes a cable tray base plate, the bottom ends of the cable tray base plate are provided with guide plates, the sides of the cable tray base plate are symmetrically provided with cable tray side plates, the sides of the cable tray side plates are provided with a plurality of evenly distributed first fixing holes, and the ends of the cable tray body are slidably provided with telescopic joints.

[0007] The telescopic joint includes a telescopic base plate, a connecting plate at one end of the telescopic base plate, a fixing plate at the bottom of the connecting plate located below the cable tray base plate, telescopic side plates symmetrically arranged on both sides of the telescopic base plate located inside the cable tray side plates, a limiting post on the outer end face of the telescopic side plate, a second fixing hole communicating with the first fixing hole through the telescopic side plate, a baffle at one end of the telescopic side plate, a support plate located outside the cable tray side plate and connected to the limiting post on the baffle, an L-shaped drive plate at one end of the support plate, and a drive post slidably arranged on the drive plate that can pass through the first fixing hole and be inserted into the second fixing hole.

[0008] As a preferred embodiment of this utility model, a guide groove that matches the guide plate is provided on the top end face of the fixing plate.

[0009] The above technical solution, by using the guide groove and guide plate, improves the connection strength and stability between the fixing plate and the cable tray base plate.

[0010] As a preferred technical solution of this utility model, a limiting groove for the displacement of the limiting column is provided through the side plate of the cable tray.

[0011] By using the above technical solution and the setting of the limiting groove, the displacement of the expansion joint can be limited.

[0012] As a preferred embodiment of this utility model, a stop plate is coaxially provided on the outer side of the drive plate and located on the outer side of the bridge side plate, and a drive spring is coaxially sleeved on the outer side of the drive column between the stop plate and the drive plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In use, first pull the drive column outward to disengage its front end from the first and second fixing holes. Then, through the cooperation of the limiting column and the limiting groove, the expansion joint slides outward, allowing the operator to extend the cable tray's usability to a certain extent. When the expansion joint is adjusted to the appropriate position, the second fixing hole on the expansion joint connects with one of the first fixing holes on the cable tray body. Loosening the drive column allows it to pass through the first fixing hole and insert into the second fixing hole under the action of the drive spring, thus limiting and fixing the expansion joint's displacement. This invention allows operators to modify the cable tray's usability according to the on-site installation conditions, enabling the cable tray to extend or retract to a certain extent in different installation scenarios, greatly improving its applicability.

[0022] Example

[0023] This utility model provides a telescopically adjustable cable tray, see reference. Figure 1-4 As shown, the cable tray body 1 is provided with expansion joints 2 at both ends. This utility model allows the staff to change the usage form of the cable tray according to the on-site installation conditions. It can extend and retract the cable tray to a certain extent in different installation scenarios, which greatly improves its applicability. At the same time, when the expansion joints are not in use, it improves the strength and load-bearing capacity of the ends of the cable tray body 1.

[0024] refer to Figure 3 The cable tray body 1 shown includes a cable tray base plate 101. Both ends of the bottom of the cable tray base plate 101 are provided with guide plates 102 in a trapezoidal structure. The guide plates 102 and the cable tray base plate 101 are integrally formed. The cable tray base plate 101 is symmetrically provided with cable tray side plates 103 on both sides. Both sides of the cable tray side plates 103 are provided with a plurality of evenly distributed first fixing holes 105.

[0025] The cable tray side plate 103 is provided with a limiting groove 104 for the displacement of the limiting column. The limiting groove 104 can limit the displacement of the expansion joint 2 and prevent the expansion joint 2 from disengaging from the cable tray body 1.

[0026] refer to Figure 4 The telescopic joint 2 shown includes a telescopic base plate 201. One end of the telescopic base plate 201 is provided with a connecting plate 202. The bottom of the connecting plate 202 is provided with a fixing plate 203 located below the cable tray base plate 101. The telescopic base plate 201 is symmetrically provided with telescopic side plates 207 located inside the cable tray side plates 103. The outer end face of the telescopic side plate 207 is provided with a limiting post. The telescopic side plate 207 is provided with a second fixing hole 208 that is connected to the first fixing hole 105. One end of the telescopic side plate 207 is welded with a baffle 206.

The outer side of the support plate 205 away from the port of the cable tray body 1 is provided with an L-shaped drive plate 209. The drive plate 209 is slidably provided with a drive post 210 that can pass through the first fixing hole 105 and be inserted into the second fixing hole 208.

[0027] The top end face of the fixing plate 203 is provided with a guide groove 204 that matches the guide plate 102. The connection strength and stability between the fixing plate 203 and the cable tray base plate 101 are improved by setting the guide groove 204 and the guide plate 102, and the connection strength between the bottom of the expansion joint 2 and the bottom of the cable tray body 1 is also improved.

[0028] The drive plate 209 is coaxially provided with a stop plate 211 located on the outer side of the bridge side plate 103. A drive spring 212 is coaxially sleeved on the outer side of the drive column 210 between the stop plate 211 and the drive plate 209. One end of the drive spring 212 is connected to the stop plate 211, and the other end of the drive spring 212 is connected to the inner side wall of the drive plate 209.

[0029] The working principle of this utility model is as follows:

[0030] In use, firstly, pull the drive column 209 outward to disengage its front end from the first fixing hole 105 and the second fixing hole 208. Then, through the cooperation of the limiting column and the limiting groove 104, the expansion joint 2 slides outward, facilitating the extension of the cable tray's usability to a certain extent. When the expansion joint 2 is adjusted to a suitable position, the second fixing hole 208 on the expansion joint 2 connects with one of the first fixing holes 105 on the cable tray body 1. Loosen the drive column 210 so that it passes through the first fixing hole 105 and inserts into the second fixing hole 208 under the elastic force of the drive spring 212, thereby limiting and fixing the displacement of the expansion joint 2. This utility model allows workers to modify the usability of the cable tray body 1 according to the on-site installation conditions, enabling the cable tray body 1 to extend or retract to a certain extent in different installation scenarios, greatly improving its applicability.
