Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and specifically to a waterproof cable tray structure. Background Technology

[0002] Cable trays are structural devices used to support and protect cables and wires, providing physical support for the cables and preventing them from being damaged by their own weight or external forces. They come in various shapes such as trough, tray, ladder, and mesh.

[0003] Chinese Patent Publication No. CN222191701U discloses an outdoor cable tray, including a tray body and a top plate. The top plate is installed on top of the tray body. Main ventilation openings are provided on both the left and right sides of the tray body. A trapezoidal groove is provided on the inner side of the tray body. A water outlet is provided in the middle of the bottom of the tray body. It also includes a water baffle and a placement plate. Sliding grooves are provided on both sides of the inner side of the tray body, and the placement plate is slidably installed in the sliding grooves. This outdoor cable tray achieves waterproofing through the placement plate, water baffle, and drainage outlet, preventing rainwater from damaging the internal cables. The heat dissipation vents and secondary ventilation openings facilitate good ventilation and heat dissipation, thus preventing overheating and burning of the cables. Furthermore, the device includes a partition plate for easy cable separation, which helps to ensure orderly cable placement and avoids misalignment that could affect subsequent maintenance by workers. It is highly practical.

[0004] In the aforementioned prior art, when splicing adjacent cable trays, it is necessary to insert the positioning head on one cable tray into the positioning groove of another cable tray. Due to the limited number of connection points, gaps are easily generated at the connection between the two cable trays, and rainwater can easily seep in from the connection and come into contact with the internal cables, causing water erosion. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a waterproof cable tray structure to solve the problems mentioned in the background art, such as the limited number of connection points between adjacent outdoor cable trays, the ease with which gaps can form at the connections, and the potential for rainwater to seep in and contact with the internal cables, causing water erosion.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A waterproof cable tray structure, comprising:

[0008] Multiple sets of cable trays are installed.

[0009] A connection structure is arranged between two adjacent cable trays to connect the two cable trays;

[0010] A sealing structure is arranged on the connection structure and the corresponding cable tray to increase the sealing between the two cable trays;

[0011] The limiting structure is arranged on the sealing structure and the corresponding cable tray for installing and fixing adjacent cable trays.

[0012] Preferably, the connection structure includes:

[0013] U-shaped connector;

[0014] The U-shaped channel is formed inside the cable tray, and the U-shaped connecting bracket is movably installed inside the U-shaped channel;

[0015] Two U-shaped rubber strips are arranged on the inner walls of the two sides of the U-shaped groove, and the two U-shaped rubber strips are in contact with the two sides of the U-shaped connecting frame.

[0016] Preferably, the connection structure further includes a positioning groove, which is formed inside the cable tray and communicates with the U-shaped groove. The U-shaped connecting frame is detachably installed inside the positioning groove, and the positioning groove is adapted to the U-shaped connecting frame.

[0017] Preferably, the sealing structure includes:

[0018] H-type mounting strip;

[0019] Two rubber sealing gaskets are respectively arranged on both sides of the H-shaped mounting strip;

[0020] Two rubber sealing gaskets are movably mounted on two adjacent cable trays, and the two rubber sealing gaskets are in contact with the corresponding two U-shaped connecting brackets.

[0021] Preferably, the limiting structure includes:

[0022] The movable plate is slidably installed inside the H-shaped mounting strip;

[0023] A limiting plate is placed on one side of the movable plate;

[0024] Two limiting strips are symmetrically arranged on one side of the limiting plate;

[0025] Two U-shaped retaining strips are respectively arranged on the inner walls of the two cable trays, and the two U-shaped retaining strips are movably sleeved on the two limiting strips;

[0026] Positioning components, arranged on the U-shaped connector and cable tray, are used to limit the position of the U-shaped connector and cable tray.

[0027] Preferably, the positioning component includes:

[0028] Several positioning holes are evenly distributed inside the limiting plate;

[0029] Positioning rod one and positioning rod two are respectively arranged on the inner wall of the cable tray and the U-shaped connecting frame, and positioning rod one and positioning rod two are respectively inserted into the corresponding two positioning holes.

[0030] Preferably, the limiting structure further includes a connecting component arranged on two adjacent cable trays for splicing the two cable trays.

[0031] Preferably, the connection component includes:

[0032] Two connecting strips are respectively arranged on one side of the two cable trays;

[0033] Several mounting bolts pass through the two connecting strips and are threaded onto the inside of the movable plate.

[0034] The beneficial effects of this utility model are as follows:

[0035] This invention allows for the splicing of adjacent cable trays by inserting a U-shaped connecting bracket into two cable trays. During insertion, the U-shaped connecting bracket compresses the U-shaped rubber strip, causing it to adhere tightly to the surface of the bracket due to its elasticity. Subsequently, an H-shaped mounting strip connects the upper and lower cable trays to form a single unit. Cables can pass through and be laid in the space between the four cable trays. The rubber sealing gasket on the H-shaped mounting strip and the U-shaped rubber strip enhance the sealing at the connections of each cable tray, thereby improving the overall waterproofing effect of the cable trays, preventing liquid from seeping into the trays, and protecting the cable insulation from water erosion.

[0036] In this invention, after the cable tray, U-shaped connecting frame, and H-shaped mounting strip are installed, pulling the movable plate can cause the limiting strip to be inserted into the U-shaped locking strip, preventing vertical displacement of the upper and lower cable trays. At the same time, it can cause the positioning holes to be fitted onto the corresponding positioning rods one and two, preventing horizontal displacement of the cable tray and U-shaped connecting frame. Then, by using mounting bolts to pass through the corresponding connecting strips and screw them into the movable plate, the movable plate can be prevented from loosening, and the splicing stability of the cable tray can be improved.

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0047] Example 1:

[0048] like Figures 1 to 6 As shown, this utility model provides a waterproof cable tray structure, including: multiple sets of cable trays 1 and a connection structure arranged between two adjacent cable trays 1 for connecting the two cable trays 1.

[0049] The connection structure includes a U-shaped connecting frame 2 and a U-shaped groove 201 inside the cable tray 1. The U-shaped connecting frame 2 is movably installed in the U-shaped groove 201. Two U-shaped rubber strips 202 are respectively arranged on the inner walls of both sides of the U-shaped groove 201. The two U-shaped rubber strips 202 are in contact with the two sides of the U-shaped connecting frame 2. When the U-shaped connecting frame 2 is inserted into the corresponding U-shaped groove 201 on the cable tray 1, the U-shaped connecting frame 2 will squeeze the U-shaped rubber strips 202 on the inner walls of both sides of the U-shaped groove 201, causing the U-shaped rubber strips 202 to bend under pressure and adhere to the surface of the U-shaped connecting frame 2, which can improve the sealing of the connection between the U-shaped connecting frame 2 and the cable tray 1.

[0050] The connection structure also includes a positioning groove 203 that is opened inside the cable tray 1 and communicates with the U-shaped groove 201. The U-shaped connecting frame 2 is detachably installed inside the positioning groove 203. The positioning groove 203 is adapted to the U-shaped connecting frame 2. The positioning groove 203 can prevent the position of the U-shaped connecting frame 2 from shaking or shifting.

[0051] Example 2:

[0052] Based on Example 1, in order to improve the waterproof effect of the cable tray 1, a sealing structure for increasing the sealing between the two cable trays 1 is arranged on the connecting structure and the corresponding cable tray 1.

[0053] The sealing structure includes an H-shaped mounting strip 3 and two rubber sealing gaskets 301 arranged on both sides of the H-shaped mounting strip 3. The two rubber sealing gaskets 301 are movably sleeved on two adjacent cable trays 1. The two rubber sealing gaskets 301 are in contact with the corresponding two U-shaped connecting frames 2. By placing the H-shaped mounting strip 3 on a set of spliced ​​U-shaped connecting frames 2 and cable trays 1, the rubber sealing gaskets 301 can be sleeved on and in contact with the end faces of the cable trays 1 and U-shaped connecting frames 2. The rubber sealing gaskets 301 can increase the sealing between the H-shaped mounting strip 3 and the U-shaped connecting frames 2 and cable trays 1.

[0054] Example 3:

[0055] Based on Embodiment 2, in order to improve the stability of the connection between adjacent cable trays 1, a limiting structure for installing and fixing adjacent cable trays 1 is arranged on the sealing structure and the corresponding cable tray 1.

[0056] The limiting structure includes a movable plate 4 slidably installed inside the H-shaped mounting strip 3, a limiting plate 401 arranged on one side of the movable plate 4, two limiting strips 402 symmetrically arranged on one side of the limiting plate 401, two U-shaped clips 403 respectively arranged on the inner walls of the two cable trays 1, the two U-shaped clips 403 respectively movably sleeved on the two limiting strips 402, and positioning components arranged on the U-shaped connecting frame 2 and the cable tray 1 to limit their position. Pulling the movable plate 4 outward can drive the limiting plate 401 to move, and the limiting plate 401 can drive the limiting strips 402 to insert into the U-shaped clips 403 on the inner walls of the upper and lower cable trays 1. Under the restriction of the limiting strips 402 and the U-shaped clips 403, vertical displacement of the upper and lower connected cable trays 1 can be avoided.

[0057] Specifically, the positioning component includes several positioning holes 404 evenly opened inside the limiting plate 401, and positioning rod 1 405 and positioning rod 2 408 respectively arranged on the inner wall of the cable tray 1 and the U-shaped connecting frame 2. Positioning rod 1 405 and positioning rod 2 408 are respectively inserted into the corresponding two positioning holes 404. The moving limiting plate 401 will drive the several positioning holes 404 to be sleeved on the corresponding positioning rod 1 405 and positioning rod 2 408, which can prevent the cable tray 1 and the U-shaped connecting frame 2 from sliding.

[0058] The limiting structure also includes a connecting component arranged on two adjacent cable trays 1 for splicing the two cable trays 1.

[0059] Specifically, the connecting assembly includes two connecting strips 406 respectively arranged on one side of the two cable trays 1, and several mounting bolts 407 passing through the two connecting strips 406 and threaded inside the movable plate 4. Continuously pulling the movable plate 4 can align the screw holes with the mounting holes on the connecting strips 406. At this time, the mounting bolts 407 can be passed through the mounting holes of the upper and lower connecting strips 406 and screwed into the movable plate 4 to reinforce the connection between the upper and lower cable trays 1.

[0060] Working principle: During installation, first insert the U-shaped connector 2 into the U-shaped groove 201 on the corresponding cable tray 1. Upon insertion, the U-shaped connector 2 will compress the U-shaped rubber strips 202 on both sides of the inner wall of the U-shaped groove 201, causing the U-shaped rubber strips 202 to bend under pressure. Under the elastic force of the U-shaped rubber strips 202, they will adhere to the surface of the U-shaped connector 2. Continuously pushing the U-shaped connector 2 will insert it into the positioning groove 203. Then, insert the U-shaped connector 2 into another cable tray 1 to achieve splicing between two adjacent cable trays 1. After splicing the two sets of cable trays 1, place the H-shaped mounting strip 3 on the spliced ​​set of U-shaped connector 2 and cable tray 1, allowing the rubber sealing gasket 301 to be fitted onto and in contact with the end faces of the cable tray 1 and U-shaped connector 2. Then, place the other set of cable tray 1 and U-shaped connector 2 on the H-shaped mounting strip 3. (Refer to the previous instructions.) Figure 2 and Figure 4 In this configuration, the two sets of cable trays 1 and U-shaped connecting frames 2 can be spliced ​​together using three sets of H-shaped mounting strips 3, as per reference. Figure 3 After completion, pull the movable plate 4 outward away from the cable tray 1, causing the movable plate 4 to move the limiting plate 401. The moving limiting plate 401 can drive the limiting strip 402 to insert into the U-shaped clip 403 on the inner wall of the upper and lower cable trays 1. Under the restriction of the limiting strip 402 and the U-shaped clip 403, the vertical displacement of the upper and lower connected cable trays 1 can be avoided. At the same time, the moving limiting plate 401 will drive several positioning holes 404 to be fitted onto the corresponding positioning rod 1 405 and positioning rod 2 408, which can prevent the cable tray 1 from sliding with the U-shaped connecting frame 2, and at the same time prevent the cable tray 1 from displacing horizontally. Continuously pulling the movable plate 4 can align its screw holes with the mounting holes on the connecting strip 406. At this time, the mounting bolt 407 can be passed through the mounting holes of the upper and lower connecting strips 406 and screwed into the movable plate 4, which can prevent the position of the movable plate 4 from loosening or shifting, and at the same time reinforce the connection of the upper and lower cable trays 1. This completes the splicing operation.
