Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to an adjustable cable tray. Background Technology

[0002] Cable trays are rigid structural systems used to support, protect, and manage cables. They directly support cables using components such as trays or ladders, forming a stable and rigid system suitable for independent installation or attachment to buildings, pipe racks, and other similar installations.

[0003] However, in the existing technology, cables placed in cable trays are generally bound in the cable trays with cable ties to ensure their stability when placed in the cable trays. However, the operation of binding and fixing with cable ties is relatively time-consuming and labor-intensive, resulting in low efficiency of cable laying in cable trays. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies: In order to ensure the stability of the cable when placed in the cable tray, the cable is generally bound in the cable tray with cable ties. However, the operation of binding and fixing with cable ties is time-consuming and labor-intensive, resulting in low efficiency of cable laying in the cable tray.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable cable tray, comprising a cable tray body, a top cover slidably connected to the upper end of the cable tray body, and a support frame fixedly connected to the lower end of the inner surface of the cable tray body. A spring is fixedly fixed to the lower surface of the top cover, and a pressing plate is fixedly connected to one end of the spring. Track columns are connected through both ends of the pressing plate, and one end of the track column is fixedly connected to the lower surface of the top cover. A blocking plate is fixedly connected to the upper surface of the pressing plate, and a fixing plate is placed between the pressing plate and the blocking plate. A rotating shaft is fixedly connected to one end of the fixing plate. The rotating shaft is rotatably connected to the top cover, and a torsion plate is fixedly connected to one end of the rotating shaft.

[0006] In a preferred embodiment, a limiting plate is fixedly connected to the end of the track column away from the top cover.

[0007] In a preferred embodiment, rubber anti-slip pads are fixedly connected to one side surface of both the support frame and the pressing plate.

[0008] In a preferred embodiment, positioning bolts are threaded at the four corner edges of the cable tray body and the top cover.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] This invention involves laying the cable in the groove on the support bracket, then sliding the top cover above the cable tray body. A twisting plate changes the cable tray from horizontal to vertical, causing the rotating shaft and fixing plate to rotate and move. This allows the fixing plate to move out of the obstruction plate's coverage area, releasing the restriction on the pressing plate and obstruction plate. The spring's return then pushes the pressing plate downwards along the track column, pressing and fixing the cable on the support bracket. This avoids the need for cable ties, making the process simple and quick, effectively improving the efficiency of cable laying on the cable tray body. Furthermore, with the help of the spring and pressing plate, it can adaptively adjust the pressing and fixing of cables of different thicknesses, enhancing its practicality.

[0016] 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.

[0017] Example 1

[0018] like Figure 1-3As shown, this utility model provides a technical solution: an adjustable cable tray, including a cable tray body 1, a top cover 2 slidably connected to the upper end of the cable tray body 1, and a support frame 3 fixedly connected to the lower end of the inner surface of the cable tray body 1. By laying each cable one by one on the groove of the support frame 3, the placement preparation work before fixing the cable is realized. A spring 4 is fixed to the lower surface of the top cover 2, and a pressing plate 5 is fixedly connected to one end of the spring 4. When the top cover 2 is slidably installed above the cable tray body 1, the pressing plate 5 is pressed and fixed by the continuous pushing of the spring 4. Track posts 6 are connected through both ends of the pressing plate 5, and one end of the track post 6 is fixedly connected to the lower surface of the top cover 2. With the help of the track posts 6, the extension and contraction of the spring 4 and the linear movement stability of the pressing plate 5 are improved. A blocking plate 8 is fixedly connected to the upper surface of the pressing plate 5, and a fixing plate 9 is placed between the pressing plate 5 and the blocking plate 8. One end of the fixed plate 9 is fixedly connected to a rotating shaft 10, which is rotatably connected to the top cover 2. A torsion plate 11 is fixedly connected to one end of the rotating shaft 10. When the top cover 2 has not yet been fully slidably installed above the cable tray body 1, the fixed plate 9 is positioned below the blocking plate 8, thus limiting the downward movement of the blocking plate 8 and the pressing plate 5. This prevents the pressing plate 5 from prematurely moving downwards due to the spring 4's rebound before the top cover 2 is fully installed on the cable tray body 1. The movement of the top cover 2 on the cable tray body 1 causes obstruction to the installation of the top cover 2. When the top cover 2 is installed on the cable tray body 1, the torsion plate 11 is twisted to change it from horizontal to vertical, which causes the rotating shaft 10 and the fixed plate 9 to rotate and move, allowing the fixed plate 9 to move out of the coverage of the blocking plate 8, releasing the restriction on the pressing plate 5 and the blocking plate 8. Then, the spring 4 rebounds and pushes the pressing plate 5 down along the track column 6, so that the pressing plate 5 presses and fixes the cable on the support frame 3. It is simple and quick.

[0019] Example 2

[0020] like Figure 1-3 As shown, a limiting plate 7 is fixedly connected to the end of the track column 6 away from the top cover 2. The limiting plate 7 limits the movement of the pressing plate 5 on the track column 6, thereby effectively preventing the pressing plate 5 from detaching from the track column 6. Rubber anti-slip pads 12 are fixedly connected to one side surface of the support frame 3 and the pressing plate 5. With the help of the rubber anti-slip pads 12, the friction between the support frame 3 and the pressing plate 5 and the cable contact surface is increased, thereby effectively improving the stability of the pressing plate 5 when pressing and fixing the cable. Positioning bolts 13 are threadedly connected to the four corner edges of the cable tray body 1 and the top cover 2. With the help of the positioning bolts 13, the top cover 2 is installed and positioned above the cable tray body 1, ensuring the stability of the connection of the top cover 2 above the cable tray body 1.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
