Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, specifically an adjustable width modular cable tray. Background Technology

[0002] Cable trays are infrastructure used to support and protect cables. They consist of components such as trays, ladders, bends, accessories, and supports, forming a continuous and rigid structural system. By laying cables within the trays, cables can be arranged and secured in an orderly manner, preventing them from becoming tangled or damaged. Their applications are wide-ranging. In the construction industry, they are used for internal cable routing in shopping malls and office buildings. In the industrial sector, chemical plants and manufacturing workshops use them to ensure the safe and stable operation of cables. In the energy sector, power plants and substations use them to rationally plan cable routes. In the transportation sector, subway and high-speed rail tunnels and stations also rely on them for cable laying to ensure the normal power and signal transmission of various facilities.

[0003] An existing patent (publication number: CN222785726U) discloses an assembled cable tray that can adapt to different scenarios and cable laying requirements, improving the system's flexibility and adaptability; however, this cable tray cannot be modularly expanded quickly, making it unsuitable for environments with different numbers of cables, thus limiting its applicability. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an adjustable width modular cable tray, which effectively solves the problem that the existing cable trays cannot be modularly expanded quickly, thus making them unsuitable for environments with different numbers of cables and limiting their applicability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-width modular cable tray, comprising a tray body, with insertion slots on both sides of the tray body, and extension frames inserted into the two insertion slots; a handwheel is provided at the center of the top of the tray body, with an upper turntable fixedly installed at the bottom of the handwheel; a plug rod is movably inserted into one side of the surface of the upper turntable; a pull ring is fixedly installed at the top of the plug rod; a push plate is fixedly installed at the lower part of the surface of the plug rod; a telescopic spring is sleeved on the upper part of the surface of the plug rod, with both ends of the telescopic spring fixedly connected to the upper turntable and the push plate respectively; a first insertion hole is provided at the center of the top of the tray body, with the lower end of the plug rod inserted into the first insertion hole; and a second insertion hole is provided at the center of the top of the tray body, at a position 90° away from the first insertion hole with the handwheel as the center.

[0006] The cable tray body has four movable locking rods at the top and bottom corners. The two extension frames have locking holes at both ends of the upper and lower parts. The lower part of the handwheel has a transmission component, which is connected to the eight locking rods. When the handwheel is rotated, the power is output to the eight locking rods through the transmission component, causing the eight locking rods to disengage or engage with the eight locking holes.

[0007] Preferably, the transmission assembly includes a shaft, which is fixedly installed at the bottom of the upper turntable. The surface of the shaft is rotatably installed in the middle of the cable tray body through two bushings. The bottom end of the shaft extends to the bottom of the cable tray body and is fixedly installed on the lower turntable.

[0008] Preferably, two transmission rods are symmetrically and rotatably installed on the sides of the lower and upper turntables that are away from each other. A push bar is rotatably installed on the end of the transmission rod away from the lower and upper turntables. A roller is tightly attached to the end of the push bar near the main body of the cable tray. A support arm is rotatably installed on the side of the roller near the main body of the cable tray. The two ends of the four support arms near the main body of the cable tray are respectively fixedly connected to eight locking rods. Two support frames are fixedly installed on the side of the four support arms away from the main body of the cable tray. A sliding rod is movably inserted into the middle of one end of each support frame. One end of each sliding rod is fixedly connected to the main body of the cable tray. A return spring is sleeved on the surface of each sliding rod. The two ends of the return spring are respectively fixedly connected to the support frame and the support arm.

[0009] Preferably, each of the push bars has a slider fixedly installed at the other end near the main body of the cable tray, and two grooves are respectively opened on the upper and lower surfaces of the main body of the cable tray, with four sliders slidably installed inside the four grooves.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When expansion is required, the operator pulls the plug rod upward through the pull ring, thereby pulling the plug rod out of the first insertion hole and squeezing the telescopic spring to retract. Then, the operator rotates the handwheel 90° clockwise. When the handwheel rotates, it drives the shaft to rotate inside the two bushings through the upper turntable. When the shaft rotates, it drives the lower turntable to rotate. When the lower turntable and the upper turntable rotate, they both pull the push bar to move inward through the transmission rod. When the push bar moves, it drives the slider to slide inside the slide groove, which increases the stability of the push bar when it moves. When the push bar moves inward, it releases the squeezing of the roller, thereby pushing the support frame under the elastic force of the return spring. When the support frame is pushed, it drives the locking rod to exit the locking hole through the support arm to release the limit, thereby allowing the two expansion frames to be pulled out from the two insertion holes to complete the disassembly.

[0011] The operator then inserts the two wider expansion brackets into the two sockets, and then rotates the handwheel 90° in the opposite direction. This causes the handwheel to push the push bar outward via the upper and lower turntables and the transmission rod. As the push bar moves outward, it smoothly compresses the support arm through the rollers. As the support arm moves, it causes the locking rod to engage with the locking hole for limitation. Finally, the operator releases the pull ring, which, under the elastic force of the telescopic spring, pushes the push plate. This causes the push plate to re-insert the plug rod into the first socket for locking, preventing the handwheel from rotating. This quickly achieves modular expansion, making this cable tray suitable for environments with different numbers of cables, and thus has a wide range of applications. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 6 The present invention includes a cable tray body 1, with insertion ports 23 on both sides of the cable tray body 1. An extension frame 2 is inserted into each of the two insertion ports 23. A handwheel 3 is provided in the middle of the upper part of the cable tray body 1. An upper turntable 10 is fixedly installed at the bottom of the handwheel 3. An insertion rod 4 is movably inserted into one side of the surface of the upper turntable 10. A pull ring 5 is fixedly installed at the top of the insertion rod 4. A push plate 6 is fixedly installed at the lower part of the surface of the insertion rod 4. A telescopic spring 7 is sleeved on the upper part of the surface of the insertion rod 4. The two ends of the telescopic spring 7 are fixedly connected to the upper turntable 10 and the push plate 6 respectively. A first insertion hole 8 is provided in the middle of the top of the cable tray body 1. The lower end of the insertion rod 4 is inserted into the first insertion hole 8. A second insertion hole 9 is provided in the middle of the top of the cable tray body 1 at a position 90° away from the first insertion hole 8 with the handwheel 3 as the center.

[0023] The cable tray body 1 has four movable locking rods 24 at the top and bottom corners. The two extension frames 2 have locking holes 25 at both ends of the upper and lower parts. The lower part of the handwheel 3 is equipped with a transmission component, which is connected to the eight locking rods 24. When the handwheel 3 rotates, the power is output to the eight locking rods 24 through the transmission component, so that the eight locking rods 24 can be disengaged or engaged in the eight locking holes 25.

[0024] When expansion is needed, the operator pulls the plug rod 4 upward through the pull ring 5, thereby pulling the plug rod 4 out of the first insertion hole 8 and squeezing the telescopic spring 7 to retract. Then the operator rotates the handwheel 3 90° clockwise. When the handwheel 3 rotates, it drives the locking rod 24 out of the inside of the locking hole 25 through the transmission component to release the limit, so that the two expansion brackets 2 can be pulled out from the two insertion holes 23 to complete the disassembly.

[0025] The operator then inserts the two wider expansion brackets 2 into the two sockets 23, and then rotates the handwheel 3 90° in the opposite direction. This causes the handwheel 3 to drive the locking rod 24 through the transmission component to engage with the locking hole 25 for limiting. Finally, the operator releases the pull ring 5, which, under the elastic force of the telescopic spring 7, pushes the push plate 6. This causes the push plate 6 to drive the insertion rod 4 back into the first socket 8 for locking, preventing the handwheel 3 from rotating. This allows for rapid modular expansion, making the cable tray suitable for environments with different numbers of cables and thus having a wide range of applications.

[0026] The transmission assembly includes a shaft 18, which is fixedly mounted on the bottom of the upper turntable 10. The surface of the shaft 18 is rotatably mounted on the middle of the cable tray body 1 via two bushings 19. The bottom end of the shaft 18 extends to the bottom of the cable tray body 1 and is fixedly mounted on a lower turntable 20. Two transmission rods 11 are symmetrically rotatably mounted on the opposite sides of the lower turntable 20 and the upper turntable 10. Pushing bars 12 are rotatably mounted on the ends of the transmission rods 11 away from the lower and upper turntables 10. Rollers 1 are tightly attached to the ends of the pushing bars 12 near the cable tray body 1. 3. Each roller 13 is rotatably mounted with a support arm 14 on the side near the main body 1 of the cable tray. The two ends of the four support arms 14 on the side near the main body 1 of the cable tray are respectively fixedly connected to eight clamps 24. Two support frames 17 are respectively fixedly mounted on the side of the four support arms 14 away from the main body 1 of the cable tray. A sliding rod 21 is movably inserted into the middle of one end of each support frame 17. One end of each sliding rod 21 is fixedly connected to the main body 1 of the cable tray. A return spring 22 is sleeved on the surface of each sliding rod 21. The two ends of the return spring 22 are respectively fixedly connected to the support frame 17 and the support arm 14.

[0027] When the handwheel 3 rotates in the forward direction, it drives the shaft 18 to rotate inside the two bushings 19 via the upper turntable 10. When the shaft 18 rotates, it drives the lower turntable 20 to rotate. When the lower turntable 20 and the upper turntable 10 rotate, they both pull the push bar 12 to move inward through the transmission rod 11. When the push bar 12 moves inward, it releases the pressure on the roller 13. Thus, under the elastic force of the return spring 22, it pushes the support frame 17. When the support frame 17 is pushed, it drives the locking rod 24 to exit the inside of the locking hole 25 through the support arm 14 to release the limit. Thus, the two extension frames 2 can be pulled out from the two insertion ports 23 to complete the disassembly.

[0028] When the handwheel 3 rotates in both directions, it pushes the push bar 12 to move outward through the upper turntable 10, the lower turntable 20, and the transmission rod 11. When the push bar 12 moves outward, it smoothly squeezes the support arm 14 through the roller 13. When the support arm 14 moves, it drives the locking rod 24 to engage inside the locking hole 25 for limiting.

[0029] Each push bar 12 has a slider 15 fixedly installed at the other end near the cable tray body 1. Two grooves 16 are opened on the upper and lower surfaces of the cable tray body 1 respectively, and the four sliders 15 are slidably installed inside the four grooves 16.

[0030] When the push bar 12 moves, it drives the slider 15 to slide inside the groove 16, which increases the stability of the push bar 12 when it moves.
