Description

Technical Field

[0001] This utility model relates to the technical field of cable tray support devices, specifically a cable tray support arm suitable for multiple cable trays. Background Technology

[0002] In the existing technology, traditional cable tray support arms have the following significant problems: On the one hand, their structure is mostly fixed, making it difficult to flexibly adjust according to the actual width and thickness of the cable tray. When facing different specifications of cable trays, different models of support arms need to be frequently replaced, which not only increases material costs, but also wastes a lot of installation time due to repeated disassembly and assembly. Moreover, the stability after fixing is insufficient, which easily leads to the risk of the cable tray shaking or even falling off.

[0003] On the other hand, the traditional cable tray support installation process relies on tools such as bolts for complex fixing, which is cumbersome, time-consuming and labor-intensive. Especially when multiple layers of cable trays need to be installed or the number of layers needs to be adjusted later, the disassembly and reinstallation steps are complicated, which seriously restricts construction efficiency and increases the labor intensity of construction workers. It is difficult to meet the needs of modern engineering for efficient installation and flexible adjustment. Therefore, it is urgent to improve a cable tray support suitable for multiple cable trays to improve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This cable tray support arm, applicable to multiple cable trays, features an adjustment mechanism that, through the cooperation of a sliding groove and a slider at the bottom of a fixed base plate, allows the mounting bracket to move flexibly below the fixed base plate, thus adjusting the lateral position of the support arm according to the width of the cable tray. The sleeve and rod design, along with the limiting edge at the top of the rod and the protrusion at the bottom of the sleeve cavity, allows for adjustment of the support arm's longitudinal height to accommodate the thickness of the cable tray. The design of the insert rod and slot on the movable support plate, combined with locking bolts, further secures the cable tray and prevents it from wobbling. The limiting groove on the sleeve, in conjunction with wedge blocks one and two in the mounting cavity at the top of the rod and the bolts, allows wedge block two to push wedge block one by tightening the bolts, which in turn drives the top pressure rod to press against the inner wall of the sleeve, enhancing the stability of the support arm after adjustment, saving space, ensuring stability after installation, reducing replacement costs and time wasted due to structural fixation, and improving installation efficiency and the applicability of the support arm.

[0014] 2. This cable tray support arm, suitable for multiple cable trays, features a quick-installation mechanism. The mechanism utilizes a slot within the clamping seat to engage with a hemispherical ball and a locking ring on the top fixing rod of the sleeve. During installation, simply push the sleeve upwards; the hemispherical ball presses against the locking claws, causing it to move backwards. When it reaches the desired position, the locking claws, under spring pressure, push out and lock the hemispherical ball, quickly completing the fixation without the need for tools, significantly reducing installation time. For disassembly, continue pushing the sleeve upwards; the locking claws contact the upper and lower ends of the locking ring, allowing for easy disassembly. This convenient operation allows for rapid installation and disassembly via a plug-in connection, facilitating flexible selection of the number of installation layers based on actual conditions, significantly improving construction efficiency, reducing labor intensity, and solving the problems of complex and cumbersome traditional installation methods. It provides great convenience for the installation and adjustment of multiple cable trays. Attached Figure Description

Example

[0022] Based on existing technology, traditional cable tray support structures are mostly fixed designs, making it difficult to flexibly adjust them according to the actual width and thickness of the cable tray. When dealing with different specifications of cable trays, it is necessary to frequently replace different models of support arms, which not only increases material costs but also wastes a lot of installation time due to repeated disassembly and assembly. Furthermore, the stability after fixing is insufficient, and there is a risk of the cable tray shaking or even falling off. Therefore, this utility model is designed with an adjustment mechanism. Please refer to [link / reference]. Figures 1-3This utility model provides a technical solution: a cable tray support arm suitable for multiple cable trays, including a fixed base plate 1, characterized in that: the fixed base plate 1 has multiple sets of mounting holes 2 at its edge, the fixed base plate 1 is fixedly installed on the top of the wall by expansion bolts matching the mounting holes 2, a support component 3 is movably installed below the fixed base plate 1, and a support plate 4 is fixedly installed at the lower end of the support component 3; the cable tray support arm suitable for multiple cable trays includes an adjustment mechanism and a quick installation mechanism, the adjustment mechanism includes the fixed base plate 1, the bottom of the fixed base plate 1 is provided with a sliding groove 201, and a slider 203 is movably installed in the sliding groove 201.

[0025] A movable support plate 206 is fixedly installed at the bottom of the sleeve rod 205. The left movable support plate 206 is provided with a plug rod 208, and the right movable support plate 206 is provided with a slot 207. The plug rod 208 is movably installed in the slot 207. The movable support plate 206 is provided with a limiting groove 210. The end of the plug rod 208 is fixedly installed with a locking bolt 209 by thread.

[0026] The sleeve 204 is provided with a limiting groove 211, and the top of the sleeve rod 205 is provided with an installation cavity. Two sets of wedge blocks 212 are movably installed in the installation cavity. A top pressure rod 213 is fixedly installed on the outside of the wedge blocks 212. A second wedge block 214 is movably installed between the two sets of wedge blocks 212. A bolt 215 is movably installed in the second wedge block 214 through a thread.

[0027] The sliding groove 201 at the bottom of the fixed base plate 1 and the slider 203 at the top of the card holder 208 form a sliding pair. When the card holder 202 is pushed, the slider 203 moves laterally in the sliding groove 201, causing the entire support assembly 3 to move laterally. The lateral position of the support arm can be adjusted according to the width of the cable tray. The sleeve 204 and the sleeve rod 205 form a telescopic structure. Pulling the sleeve rod 205 up or down, the limiting edge and the protrusion cooperate to limit the pull-out range of the sleeve rod 205, realizing the adjustment of the longitudinal height of the support arm. When the height is adjusted to a suitable height, when the bolt 215 is tightened, the wedge block 214 moves forward, pushing the two wedge blocks 212 on both sides to expand outward, causing the top pressure rod 213 to press against the inner wall of the sleeve 204, completing the locking. Example

[0028] Based on Embodiment 1, the traditional bracket installation process relies on bolts and other tools for complex fixing, which is cumbersome, time-consuming, and labor-intensive. Especially when multi-layer cable tray installation or subsequent layer adjustments are required, the disassembly and reinstallation steps are complex, severely restricting construction efficiency and increasing the labor intensity of construction workers. This makes it difficult to meet the demands of modern engineering for efficient installation and flexible adjustment. Therefore, this utility model provides a quick installation mechanism.

[0030] When multiple cable trays need to be installed, push the sleeve 204 to be assembled upward into the bracket 202. The hemispherical ball 303 presses against the ramp at the front end of the claw 306, causing the claw 306 to compress the spring 307 and retract into the mounting groove 305. After the hemispherical ball 303 passes the claw 306, the spring 307 pushes the claw 306 out, supporting the lower end of the hemispherical ball 303 and completing the fixation. When disassembly is required, continue to push the sleeve 204 upward. The upper end of the snap ring 304 contacts the claw 306 first, and then the claw 306 is squeezed back. Continue to push the sleeve, and the lower end of the snap ring 304 passes the claw 306. Then pull the sleeve 204 downward, and the claw 306 retracts along the lower end of the snap ring, causing the sleeve 204 to disengage from the bracket 202.
