Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically a telescopic cable tray for cables. Background Technology

[0002] Cable trays are classified into trough-type cable trays, tray-type cable trays, ladder-type cable trays, and grid-type cable trays. They consist of supports, brackets, and installation accessories. They can be installed independently or laid on various building and pipe rack supports. They feature simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts must be galvanized.

[0003] Existing trough-type cable trays have fixed lengths and are cut off according to later installation requirements, which increases the complexity of their installation. At the same time, since they are installed by suspension, it is inconvenient to measure the length at the top, which leads to measurement errors and consequently, errors in the dimensions of the cable trays. This affects subsequent docking and installation, and greatly reduces the adaptability and flexibility of the cable tray installation. Utility Model Content

[0004] The purpose of this utility model is to provide a telescopic cable tray to solve the problems mentioned in the background art, such as the inability to adjust the telescopic length of the cable tray, the inability to adjust the length of the inherent length of the cable tray, which affects the subsequent docking and installation and greatly reduces the adaptability and flexibility of the cable tray installation.

[0020] 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.

[0021] Please see Figure 1-5 One embodiment of this utility model is a telescopic cable tray, comprising:

[0022] The first cable tray body 1 has a second cable tray body 2 that is externally engaged at both ends of the first cable tray body 1. The upper surface of the second cable tray body 2 is connected to an end cap 3. The lower surface of the first cable tray body 1 is fixedly connected to a threaded rod 4 that extends to the bottom of the second cable tray body 2. The threaded rod 4 is externally threaded with a locking nut 5. The lower surface of the second cable tray body 2 is fixedly connected to a baffle 7 and a handle 9. Through the interlocking of the first cable tray body 1 and the second cable tray body 2, the device can be extended and retracted, thereby achieving flexible adjustment of its length. This greatly improves the adaptability and flexibility of the device and enhances the convenience of its connection.

[0023] Furthermore, there are two second cable tray bodies 2, which are symmetrically distributed. The upper surface of the second cable tray body 2 is provided with connecting lugs. The width of the end cap 3 is equal to the maximum width of the second cable tray body 2. The end cap 3 and the second cable tray body 2 are connected by bolts to complete the covering treatment above the first cable tray body 1 and the second cable tray body 2, thereby improving the top protection effect. The width of the end cap 3 is greater than the width of the first cable tray body 1, which can perfectly cover the first cable tray body 1. At the same time, the length of the end cap 3 is greater than the length of the first cable tray body 1, which facilitates the connection and positioning of the two ends of the end cap 3 with the second cable tray body 2.

[0024] Furthermore, a fireproof rubber pad is provided on the lower surface of the end cap 3, the upper surface of the first cable tray body 1 abuts against the lower surface of the end cap 3, and a soft rubber pad 10 is adhered to the inner wall of the second cable tray body 2. By laying the soft rubber pad 10, metal contact between the first cable tray body 1 and the second cable tray body 2 is avoided, improving the smoothness of its extension and retraction adjustment, and at the same time avoiding the noise generated by metal contact friction.

[0025] Furthermore, two threaded rods 4 are respectively provided at both ends of the lower surface of the first cable tray body 1. The bottom of the threaded rod 4 is provided with a through hole, and a handle 6 passes through the through hole. Nuts are threaded to both ends of the handle 6, and the nuts abut against the outer wall of the threaded rod 4. The handle 6 facilitates the pulling control of the first cable tray body 1. Thus, while holding the handle 6 and the handle 9, the extension and retraction lengths of the first cable tray body 1 and the second cable tray body 2 can be flexibly adjusted.

[0026] Furthermore, two threaded rods 4 correspond to a set of grips 6. The center of the grips 6 is provided with an anti-slip rubber sleeve, and the outer wall of the locking nut 5 is provided with anti-slip texture. The locking nut 5 abuts against the lower surface of the second cable tray body 2. Through the abutment of the locking nut 5, the first cable tray body 1 and the second cable tray body 2 are squeezed and positioned to ensure their stability after extension and retraction adjustment.

[0027] Furthermore, the second cable tray body 2 is provided with a guide groove adapted to the movement of the threaded rod 4, and a corrugated dustproof plate 8 is connected between the guide groove and the threaded rod 4. Two sets of corrugated dustproof plates 8 are provided inside each guide groove. The corrugated dustproof plates 8 provide a good sealing and protection effect, reducing the entry of flying insects and other impurities.

[0028] Furthermore, the handle 9 is fixedly connected to one end of the two second bridge body 2 that are close to each other, and the baffle 7 is fixedly connected to the lower surface of the second bridge body 2 away from the handle 9. The horizontal end of the handle 9 is at the same level as the grip 6, and the outer wall of the horizontal end of the grip 6 is also covered with an anti-slip rubber sleeve. The anti-slip rubber sleeve improves the comfort of contact with the hand.

[0029] Working Principle: The first cable tray body 1, the second cable tray body 2, and the end cap 3 used in this application are all commercially available products. Their principles and connection methods are existing technologies well known to those skilled in the art, and therefore will not be elaborated here. When using this utility model, the device is first installed and positioned. The second cable tray body 2 is then processed to make contact and support with the hanger crossbar. The telescopic lengths of the first cable tray body 1 and the second cable tray body 2 are then adjusted. By rotating the locking nut 5, the squeezing and positioning of the first cable tray body 1 and the second cable tray body 2 is released. Then, the telescopic lengths of the first cable tray body 1 and the second cable tray body 2 are flexibly adjusted by holding the handle 6 and the handle 9. After adjusting to the appropriate position, the first cable tray body 1 and the second cable tray body 2 are squeezed and positioned by rotating the locking nut 5. Then, the installation of the baffle 7 allows the second cable tray body 2 to be better connected and positioned with the hanger crossbar. Finally, the cables are laid inside.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
