Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to a stepped power supply cable tray. Background Technology

[0002] Cable trays are structural systems used to support, protect, and manage cables, commonly found in buildings, industrial facilities, and electrical engineering. They are typically made of metal or plastic, effectively organizing cables, preventing damage, and facilitating cable laying, inspection, and maintenance. Cable trays are categorized into different types based on their usage environment and function, such as trough-type, ladder-type, and tray-type, suitable for various cables including power, communication, and control cables. They not only extend cable lifespan but also ensure the safety and neatness of the wiring system.

[0003] During cable tray installation, obstacles often exist along the installation path. In such cases, inclined cable trays are needed to connect two sections of cable trays at different heights. Due to the different angles, the ends of the inclined cable trays need to be connected to the horizontal cable trays via transition structures, causing inconvenience in installation. Furthermore, because of the different obstacles, the height difference between the two horizontal cable tray sections at different heights also varies, often requiring the use of multiple cable trays of different sizes for transition, or even custom-made ones, indicating low applicability. Utility Model Content

[0004] The purpose of this utility model is to provide a stepped power supply cable tray to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a stepped power cable tray, including a main frame with adapter frames at both ends, and a laying groove at the top of the main frame;

[0006] The adapter frame includes a base frame and side frames. Both sides of the base frame are provided with side frames located outside the main frame. One end of the base frame is hinged to one end of the main frame.

[0007] The side frame has a fan-shaped part at one end near the main frame, and the fan-shaped part has an arc-shaped hole. Both sides of the main frame have locking pins that pass through the arc-shaped hole. The axis of the arc-shaped hole is located on the rotation axis of the adapter frame.

[0008] A locking plate is fitted onto one end of the locking pin, and a locking pin is provided on the inner side of the locking plate near the side frame. The side frame has multiple pin holes around the axis of the arc-shaped hole for the locking pin to be inserted.

[0009] Furthermore, the main frame includes a concave frame and two cable tray bodies. The laying groove and locking post are both provided on the cable tray bodies. The ends of the two cable tray bodies that are far apart are hinged to the adapter frame. The concave frame is a "concave" shaped structure that bends upward on both sides. The other ends of the two cable tray bodies are inserted into the concave frame. Both sides of the concave frame are provided with fixing bolts for fixing the cable tray bodies.

[0010] Furthermore, both sides of the main body of the cable tray are provided with multiple bolt holes along the length direction for fixing bolts to pass through.

[0011] Furthermore, the concave frame is located on the outside of the cable tray body.

[0012] Furthermore, both ends of the arc-shaped hole are provided with a plurality of pin holes of the same number, and both ends of the locking plate are provided with locking pins.

[0013] Furthermore, the locking pin is a threaded rod with one end connected to the main frame and the other end threaded. The locking plate has a round hole through which the locking pin passes. The locking pin is provided with a backstop nut, which is used to limit the locking plate after the locking pin is inserted into the pin hole.

[0014] Furthermore, the locking post has a side groove on its side, and the circular hole has a side key on its wall that slides into the side groove.

[0015] Furthermore, the side of the side frame is provided with mounting holes.

[0016] The beneficial effects of this utility model are:

[0017] Firstly, this utility model adjusts the angle of the adapter frame relative to the main frame by inserting locking pins into different pin holes, thereby adjusting the height difference between the two adapter frames to adapt to the installation needs of two cable trays with different height differences.

[0018] Secondly, this utility model hinges the adapter frame to the main frame and uses the locking plate, locking pin, locking post arc-shaped hole and pin hole to adjust and fix the angle of the adapter frame, forming an integrated cable tray with height adjustment function, which is convenient for laying and installation.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] like Figures 1 to 6 As shown, a stepped power cable tray includes a main frame 2 with transfer frames 1 at both ends, and a laying groove 3 on the top of the main frame 2;

[0032] The adapter frame 1 includes a base frame 101 and a side frame 102. The base frame 101 has a side frame 102 located on both sides outside the main frame 2. One end of the base frame 101 is hinged to one end of the main frame 2.

[0033] The side frame 102 is provided with a fan-shaped part 103 at one end near the main frame 2. The fan-shaped part 103 is provided with an arc-shaped hole 4. Both sides of the main frame 2 are provided with locking pins 5 that pass through the arc-shaped hole 4. The axis of the arc-shaped hole 4 is located on the rotation axis of the adapter frame 1.

[0034] A locking plate 6 is fitted onto one end of the locking pin 5. A locking pin 7 is provided on the inner side of the locking plate 6 near the side frame 102. The side frame 102 has multiple pin holes 8 around the axis of the arc-shaped hole 4 for the locking pin 7 to be inserted. By inserting the locking pin 7 into different pin holes 8, the side frame 102, i.e., the adapter frame 1, is further limited by the locking plate 6, the locking pin 7, and the locking pin 5, so that the angle of the adapter frame 1 relative to the main frame 2 is locked.

[0035] The adapter frames 1 at both ends are used to connect to horizontal cable trays, so both adapter frames 1 are installed horizontally. The angle of the adapter frame 1 relative to the main frame 2 is adjusted according to the height difference required to avoid obstacles, that is, the tilt angle of the main frame 2 relative to the horizontal plane is adjusted, thereby adjusting the height difference between the two ends of the main frame 2 to meet the requirements for obstacle avoidance.

[0036] The base frame 101 can be plate-shaped or, as shown in the attached drawing, a bottom structure composed of multiple spaced crossbeams. The base frame 101 shown in the drawing is for consistency with the stepped power cable tray. The specific structural form can be selected according to the installation requirements and is not limited here. The base frame 101 is hinged to the main frame 2. Since the hinged structure is a conventional structure, it will not be described in detail here.

[0037] The main frame 2 includes a concave frame 201 and two cable tray bodies 203. The ends of the two cable tray bodies 203 that are far apart are hinged to the adapter frame 1. The concave frame 201 is a "U"-shaped structure with both sides bent upwards. The cable tray bodies 203 are inserted into the concave frame 201. Both ends of the concave frame 201 are provided with fixing bolts 9, and both sides of the cable tray bodies 203 are provided with multiple bolt holes 10 along the length direction for the fixing bolts 9 to pass through. When it is necessary to adjust the length of the main frame 2, the fixing bolts 9 are removed from the bolt holes 10, and then the cable tray bodies 203 are slid to adjust the distance between the adapter frame 1 and the concave frame 201. After adjustment, the fixing bolts 9 are passed through the corresponding bolt holes 10 and fixed to adjust the length of the main frame 2, thereby achieving further adjustment of the height difference between the two adapter frames 1 and enhancing the applicability of the cable tray.

[0038] Preferably, the concave frame 201 is located on the outside of the cable tray body 203 to avoid the concave frame 201 being located inside the laying groove 3 and thus having an adverse effect on the laying of cables.

[0039] A further optimization of the above embodiment is that both ends of the arc-shaped hole 4 are provided with a plurality of pin holes 8 of the same number, and both ends of the locking plate 6 are provided with locking pins 7, so as to strengthen the connection between the adapter frame 1 and the main frame 2.

[0040] A further optimization of the above embodiment is that the locking post 5 is a threaded rod with one end connected to the main frame 2 and the other end having threads. The locking plate 6 has a round hole 11 for the locking post 5 to pass through. The locking post 5 is provided with a backstop nut 12. The backstop nut 12 is used to limit the locking plate 6 after the locking pin 7 is inserted into the pin hole 8, thereby preventing the locking plate 6 from retracting along the locking post 5 and causing the locking pin 7 to exit the pin hole 8, resulting in the failure of the angle locking function of the adapter frame 1.

[0041] A further optimization of the above embodiment is that the side of the locking post 5 is provided with a side groove 13, and the wall of the round hole 11 is provided with a side key 14 that slides into the side groove 13. The side key 14 and the side groove 13 cooperate to prevent the locking plate 6 from rotating, thereby facilitating the insertion of the locking pins 7 at both ends of the locking plate 6 into the pin holes 8 on both sides of the arc-shaped hole 4.

[0042] In addition, the side of the side frame 102 is provided with mounting holes 15 to facilitate the connection between the adapter frame 1 and the connected cable tray.

[0043] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
