Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable tray technology, specifically to a cable tray with adjustable length. Background Technology
[0002] Cable trays are structures used to support and manage cables, widely used in various buildings and equipment. They are systems used to support, protect, and manage cables within buildings, underground, or between equipment. They are typically made of metallic or non-metallic materials and provide stable support, electrical conductivity protection, and mechanical protection.
[0003] Existing cable trays cannot be adjusted in length according to the cable length, requiring temporary cutting and adjustment, which greatly limits their use. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a cable tray with adjustable length.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, the present invention provides the following technical solution: an adjustable-length cable tray, comprising a first tray and two second trays, wherein the second trays are provided with an inner groove, and the two ends of the first tray can slide inside the inner groove;
[0008] The first cable tray has multiple slots symmetrically arranged on both sides, and the second cable tray has multiple cavities symmetrically arranged inside. A first spring is provided inside the cavity, and a locking block that cooperates with the slot is provided at the lower end of the spring.
[0009] Two positioning seats and a positioning rod are symmetrically arranged on the outer wall of the second cable tray. The positioning rod can pass through the positioning seat and limit the first cable tray. The positioning rod is threadedly connected to the positioning seat.
[0010] Furthermore, an improvement of this utility model is that the card block has an isosceles trapezoidal structure.
[0011] To facilitate the operation of the positioning rod, the present invention includes an improvement in that the outer end of the positioning rod is provided with a toggle lever.
[0012] To improve the stability of the positioning rod during use, the present invention includes the following improvements: the middle part of the actuating rod is provided with a groove; two support rods are symmetrically arranged on both sides of the second bridge frame; a fixing seat is fixedly provided at one end of the support rod; a second spring is provided inside the fixing seat; and a support rod that can be inserted into the groove is provided at one end of the second spring.
[0013] Furthermore, an improvement of this utility model is that the support rod has a cylindrical structure, and the actuating rod can rotate at the support rod.
[0014] Furthermore, an improvement of this utility model is that the support rod is fixed to the outer wall of the second bridge frame by screws.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a cable tray with adjustable length, which has the following advantages:
[0017] By using the combination of the locking block and the locking slot, the second cable tray and the first cable tray can be limited. Pulling the second cable tray can adjust the position of the second cable tray on the first cable tray, thereby facilitating temporary adjustment of the overall length of the cable tray and improving the applicability of this structure.
[0018] After the overall length of the structure is adjusted, the positioning rod is rotated. Through the action of the threaded structure, one end of the positioning rod can contact the first cable tray. Through the friction between the positioning rod and the first cable tray, the stability of the second cable tray at both ends of the first cable tray can be further improved, thereby improving the stability of the structure during overall use.

[0024] 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.
[0025] Please see Figure 1-4 The present invention provides a length-adjustable cable tray, comprising a first cable tray 1 and two second cable trays 2, wherein the second cable tray 2 is provided with an inner groove 3, and the two ends of the first cable tray 1 can slide inside the inner groove 3;
[0026] The first cable tray 1 has multiple slots 4 symmetrically arranged on both sides, and the second cable tray 2 has multiple cavities 5 symmetrically arranged inside. The cavity 5 is provided with a first spring, and the lower end of the spring is provided with a locking block 6 that cooperates with the slot 4.
[0027] Two positioning seats 7 and a positioning rod 8 are symmetrically arranged on the outer wall of the second cable tray 2. The positioning rod 8 can pass through the positioning seat 7 and limit the first cable tray 1. The positioning rod 8 is threadedly connected to the positioning seat 7.
[0028] When in use, the first spring provides elastic force to the locking block 6. Through the cooperation of the locking block 6 and the locking slot 4, the second cable tray 2 and the first cable tray 1 can be limited. Pulling the second cable tray 2 can adjust the position of the second cable tray 2 on the first cable tray 1, thereby facilitating temporary adjustment of the overall length of the cable tray and improving the applicability of this structure.
[0029] After the overall length of the structure is adjusted, the positioning rod 8 is rotated. Through the action of the threaded structure, one end of the positioning rod 8 can contact the first cable tray 1. Through the friction between the positioning rod 8 and the first cable tray 1, the stability of the second cable tray 2 at both ends of the first cable tray 1 can be further improved, thereby improving the stability of the structure during overall use.
[0030] In this embodiment, the card block 6 can be an isosceles trapezoidal structure.
[0031] In this embodiment, the outer end of the positioning rod 8 is provided with a toggle rod 9, and the middle part of the toggle rod 9 is provided with a groove. Two support rods 11 are symmetrically arranged on both sides of the second bridge frame 2. A fixing seat 10 is fixedly provided at one end of the support rod 11. A second spring is provided inside the fixing seat 10. A support rod 12 that can be inserted into the groove is provided at one end of the second spring. The support rod 12 is a cylindrical structure, and the toggle rod 9 can rotate at the support rod 12. The second spring can provide a spring force to the support rod 12. The second spring is in a compressed state, which makes it difficult for the positioning rod 8 to loosen. The groove provides a limiting effect between the support rod 12 and the toggle rod 9. When the toggle rod 9 is rotated, the support rod 12 will not be rotated.
[0032] In this embodiment, the support rod 11 is fixed to the outer wall of the second cable tray 2 by screws. The screw fixing method makes it easy to assemble the support rod 11 on the second cable tray 2.
