Description

Technical Field

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

[0002] Energy-saving cable trays are a production process that reduces product weight, improves product performance, significantly reduces costs, and enhances socio-economic benefits while ensuring product functionality and quality.

[0003] A socket-type energy-saving cable tray disclosed in Chinese patent CN220874152U, like other types of cable trays, requires bolts and nuts for assembly. The bolts are passed through the through holes at the ends of two adjacent cable trays, and then the nuts are threaded onto the bolt surfaces to complete the assembly. However, this socket-type energy-saving cable tray has the following drawbacks during assembly:

[0004] After the bolt is passed through the corresponding through hole, one hand needs to hold the bolt with a wrench while the other hand uses a wrench to connect the nut to the bolt surface. Since the two ends of the bolt are located inside and outside the cable tray respectively, one hand needs to be placed over the cable tray, making the overall assembly operation inconvenient and affecting assembly efficiency. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0006] Therefore, one objective of this utility model is to propose an energy-saving cable tray, which aims to solve the problem that the assembly operation of the existing socket-type energy-saving cable tray is inconvenient, resulting in low assembly efficiency.

[0007] To achieve the above objectives, one embodiment of the present invention provides an energy-saving cable tray, including a cable tray body, a cover plate fixedly installed on the top of the cable tray body, and a fixing component for fixing two adjacent cable tray bodies. Socket plates are fixedly connected to the inner walls on both sides of one end of the cable tray body. Through holes are opened on the side of the socket plates. Limiting plates are fixedly connected to the top and bottom of the inner side of the socket plates. Notches are opened on both sides of the end of the cable tray body away from the socket plates.

[0008] The fixing component includes a screw rod, one end of which is fixedly connected to a square plate. A nut is threaded onto the outer surface of the screw rod. The screw rod is inserted into the inside of the through hole, and the square plate is located inside the socket plate. The upper and lower limiting plates limit the square plate.

[0009] The beneficial effects are as follows: First, insert the screw into the inside of the through hole and connect the nut to the surface of the screw. Then, insert the two cable tray bodies together through the socket plate. Insert the screw through the notch. Since the square plate at the end of the screw cannot rotate due to the restriction of the limiting plate, when fixing, you only need to tighten the nut from the outside of the cable tray body to fix the two cable tray bodies together. Therefore, it is convenient for workers to assemble and improves assembly efficiency.

[0010] Furthermore, the bottom of the cable tray body is provided with multiple lateral protrusions, which are integrally formed by stamping, thereby improving the strength of the bottom of the cable tray body.

[0011] Preferably, as described in any of the above embodiments, the top of the cable tray body has inner grooves on both sides along its length.

[0012] The beneficial effects are: when handling the cable tray body, the hand can grasp the top of the cable tray body, and the inner groove can prevent the thin side wall from scratching the hand, thus improving safety.

[0013] Furthermore, vertical grooves are provided on both sides of the main body of the cable tray, and a fixing component is slidably connected inside the groove. Openings are provided on both sides of the cover plate at positions corresponding to the grooves, and the cover plate is fixedly installed on the top of the main body of the cable tray by the fixing component.

[0014] The beneficial effects are as follows: after the fixing component slides upward, the square plate enters the inner groove, which can limit the square plate. Therefore, when installing the cover plate, you only need to fasten the cover plate to the top of the cable tray body, then slide the fixing component upward and tighten the nut, which facilitates the fixing of the cover plate.

[0015] Preferably, in any of the above embodiments, positioning grooves are provided at the top and bottom of the notch, a clamping plate is fitted on the outer surface of the screw, and positioning plates are fixedly connected to the top and bottom of the clamping plate on the side near the square plate.

[0016] The beneficial effect is that after tightening the nut, the positioning plate on the side of the clamp can be inserted into the positioning groove, so the connection between the two cable tray bodies does not rely on the friction between the nut and the side wall of the cable tray body, but is secured in the positioning groove by the positioning plate, thus providing better stability.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] This utility model provides an energy-saving cable tray.

[0028] Example 1:

[0029] like Figure 1-3As shown, it includes a cable tray body 1, a cover plate 4, and a fixing component 3. The cable tray body 1 is a U-shaped groove with the opening facing upwards, and the cover plate 4 is a U-shaped groove with the opening facing downwards. The inner walls on both sides of one end of the cable tray body 1 are fixedly connected to a socket plate 2. The side of the socket plate 2 is provided with a through hole 21. The top and bottom of the inner side of the socket plate 2 are fixedly connected to a limit plate 22. The cable tray body 1 is provided with notches 11 on both sides at the end away from the socket plate 2. The position of the notches 11 corresponds to the through hole 21.

[0030] The fixing component 3 includes a screw 31, which is inserted into the through hole 21. One end of the screw 31 is fixedly connected to a square plate 32, which is located inside the socket plate 2. The upper and lower limiting plates 22 on the inner side of the socket plate 2 limit the square plate 32 so that the square plate 32 cannot rotate. The outer surface of the screw 31 is threaded with a nut 33. When two adjacent cable tray bodies 1 are connected, the screw 31 is inserted into the notch 11 through the opening, and then the two cable tray bodies 1 can be fixed together by tightening the nut 33.

[0031] Furthermore, such as Figure 2 As shown, the bottom of the cable tray body 1 is provided with multiple horizontal protrusions 15. The protrusions 15 are integrally formed by stamping, which can improve the strength of the bottom of the cable tray body 1 and prevent the bottom of the cable tray body 1 from bending downward under gravity, causing the two side walls of the cable tray body 1 to converge towards the middle.

[0032] Example 2:

[0033] like Figure 2 As shown, based on Embodiment 1, both sides of the top of the cable tray body 1 are provided with inner grooves 13 along its length direction. When picking up or putting down the cable tray body 1, the inner grooves 13 can prevent the thin side walls from scratching the hands when the hands grasp the top of the cable tray body 1.

[0034] Furthermore, vertical grooves 14 are provided on both sides of the cable tray body 1. The screw 31 of the fixing component 3 is inserted into the groove 14 and can slide up and down along the groove 14. The square plate 32 at the end of the screw 31 is located on the inner side of the cable tray body 1. Openings 41 are provided on both sides of the cover plate 4 at positions corresponding to the grooves 14. After the cover plate 4 is fastened to the top of the cable tray body 1, the openings 41 correspond to the screw 31. Then, the screw 31 is slid upward and inserted into the opening 41. The square plate 32 at the end of the screw 31 is inserted into the inner groove 13. The inner groove 13 can limit the square plate 32 so that it cannot rotate. Then, the nut 33 is threaded onto the outer surface of the screw 31 and tightened. The square plate 32 and the nut 33 can clamp the side wall of the cable tray body 1 and the side wall of the cover plate 4, thereby fixing the cover plate 4 to the top of the cable tray body 1.

[0035] Example 3:

[0036] like Figure 2 and Figure 5 As shown, based on Embodiment 1, positioning grooves 12 are provided at the top and bottom of the notch 11. A clamping plate 5 is fitted on the outer surface of the screw 31, and positioning plates 51 are fixedly connected to the top and bottom of the clamping plate 5 near the square plate 32. Before tightening the nut 33, the positioning plate 51 and the positioning groove 12 are aligned, and then the nut 33 is tightened so that the positioning plate 51 is inserted into the positioning groove 12. Thus, the connection between the two cable tray bodies 1 is not based on the friction between the nut 33 and the side wall of the cable tray body 1, but is secured by the positioning plate 51 in the positioning groove 12, thereby making the connection between the two cable tray bodies 1 more secure.

[0037] The working principle of this utility model is as follows: During assembly, the screws 31 of multiple fixing components 3 are first inserted into the through holes 21 and the slide grooves 14 respectively, and the nuts 33 are connected to the surface of the screws 31 (the surface of the screws 31 in the through holes 21 is first fitted with clamps 5, and then the nuts 33 are connected) to prevent the screws 31 from falling off.

[0038] When the two cable tray bodies 1 are connected, the socket plate 2 at the head of one cable tray body 1 is inserted into the tail of the other cable tray body 1. The screw 31 in the through hole 21 is inserted through the opening of the notch 11. Then, the nut 33 on the surface of the screw 31 is turned. The square plate 32 will not rotate under the restriction of the limiting plate 22. Thus, the nut 33 faces the clamping plate 5 towards the side wall of the cable tray body 1, so that the positioning plate 51 is inserted into the positioning groove 12, thereby realizing the connection between the head and tail of the two adjacent cable tray bodies 1.

[0039] When installing the cover plate 4, place the cover plate 4 on top of the cable tray body 1, then slide the screw 31 in the slide groove 14 upwards, the square plate 32 enters the inner groove 13, the screw 31 enters the opening 41, and then tighten the nut 33 so that the nut 33 and the square plate 32 clamp the side wall of the cable tray body 1 and the cover plate 4 together, thereby completing the installation of the cover plate 4.
