Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, in particular to a cable tray with good rust prevention performance. Background Technique

[0002] As a common support and protection device for cable laying in the power supply system of electrical equipment, the cable tray plays a role in protecting the cables laid in the cable tray and guiding the wire routing.

[0003] After retrieval, a patent with the Chinese patent publication number CN220066733U discloses a cable tray, which includes a cable tray main body. Legs are installed at the bottom of the cable tray main body, a transverse partition is clamped on the inner side wall of the cable tray main body, and vertical partitions are clamped on the inner cavity bottom of the transverse partition and the cable tray main body. The above patent has the following deficiencies: Although this patent can support the cables, the cable tray body is fixedly arranged and cannot be telescoped according to the actual length of the cables. Therefore, when the cable length is too short, the redundant cable bridge needs to be cut off, and the cut-off cable bridge cannot be used again, resulting in waste. In view of this, we propose a cable tray with good rust prevention performance. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cable tray with good rust prevention performance to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A cable tray with good rust prevention performance includes a base. Two cable tray bodies are arranged on the top of the base through a telescopic mechanism, and an anti-rust paint is sprayed on the outside of the cable tray bodies;

[0007] The telescopic mechanism includes a top plate, a fixed frame, a chute, a slider, a rack, a gear, a vertical shaft, a worm gear, a motor, and a worm;

[0008] The top plate is fixedly connected to the top of the base through a support rod. The fixed frame is fixedly connected to the top of the top plate. The number of the chutes is two, and the two chutes are opened on the top of the top plate. The slider is slidably connected to the top of the chute. The number of the racks is two, and the two racks are respectively slidably connected to the top of the two chutes through the sliders. The two cable tray bodies are respectively fixedly connected to the top of the two racks. The fixed frame is arranged on the top of the cable tray body and between the two racks. The movement of the slider is limited by setting the chute.

[0009] Preferably, the gear meshes with the two racks. The gear is fixedly connected to the top end of the vertical shaft. The middle part of the vertical shaft passes through the top plate rotatably through a bearing. The bottom end of the vertical shaft is rotatably connected to the base through a bearing. By setting the rotation of the gear, the two racks can be driven to move simultaneously.

[0010] Preferably, the worm gear is fixedly connected to the middle part of the vertical shaft. The motor is fixedly connected to the top of the base. The rear end of the worm is fixedly connected to the front output end of the motor. The worm gear meshes with the worm.

[0011] Preferably, a fixing mechanism is provided on the top of the bridge body. The fixing mechanism includes insertion blocks. The number of the insertion blocks is two. The two insertion blocks are fixedly connected to the left side of the left bridge body. Two slots are provided on the right side of the right bridge body. The slots are inserted with the insertion blocks. By setting the slots and the insertion blocks, when the cable is too long, the two devices can be spliced and used simultaneously.

[0012] Preferably, three clamping slots are formed on the top of the bridge body. A clamping block is clamped on the top of the clamping slot. A partition board is fixedly connected to the top of the clamping block. The clamping block is fixed by setting the clamping slot.

[0013] Preferably, the number of the support rods is four. The bottom ends of the four support rods are respectively fixedly connected to the four corners of the top of the base. The top ends of the four support rods are respectively fixedly connected to the four corners of the bottom of the top plate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By driving the worm to rotate through the motor, the rotation of the worm drives the two bridge bodies to move mirror-symmetrically. Thus, according to the actual length of the cable to be laid, the distance between the two bridges can be freely adjusted, so as to avoid waste caused by cutting the bridge body when the cable is too short.

[0016] 2. Through the mutual cooperation among the clamping slot, the clamping block and the partition board, the position of the partition board can be freely moved according to the diameter size of the actually laid cable, so that the cable can be placed more reasonably and the space utilization rate inside the bridge body can be improved.

[0025] As Figures 1-4As shown in the figure, a fixing mechanism 5 is provided on the top of the bridge body 4. The fixing mechanism 5 includes inserting blocks 51. The number of inserting blocks 51 is two. The two inserting blocks 51 are fixedly connected to the left side of the left bridge body 4. Two slots 52 are provided on the right side of the right bridge body 4. The slots 52 are inserted with the inserting blocks 51. By providing the slots 52 and the inserting blocks 51, when the cable is too long, the two devices can be spliced and used simultaneously.

[0027] The working principle of the present utility model is as follows:

[0028] When laying a cable with a very short length, the motor 39 is started to drive the worm 310 to rotate. The rotation of the worm 310 drives the worm gear 38 to rotate. The rotation of the worm gear 38 drives the vertical shaft 37 to rotate. The rotation of the vertical shaft 37 drives the gear 36 to rotate. The rotation of the gear 36 drives the two racks 35 to move simultaneously and approach each other. The simultaneous movement of the two racks 35 drives the two bridge bodies 4 to move simultaneously and approach each other. Thus, the distance between the two bridge bodies 4 is shortened, and the short cable can be laid on the two bridge bodies 4. Repeating the above operation in reverse can increase the distance between the two bridge bodies 4, and the long cable can be limited by the two bridge bodies 4 and the fixing frame 32 at the same time.

[0029] The above shows and describes the basic principle, main features, and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments.
