Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to an adjustable cable tray mounting bracket. Background Technology

[0002] With the development of modern industry and the continuous improvement of electrification, the use of cables is becoming increasingly widespread. To ensure the neat laying and safe operation of cables, cable trays, as a device for supporting cables, are widely used. Cable trays are structures used to support and protect cables; they are typically made of metal or plastic and are used to install and organize cables in buildings or industrial facilities. Cable trays can be used for horizontal or vertical cabling to ensure the safety, reliability, and ease of maintenance of cables. There are various types of cable trays, including ladder-shaped trays, pallet trays, and mesh trays.

[0003] Traditional cable trays have fixed sizes and shapes, which limits their adaptability to different installation environments or changes in engineering projects. These fixed cable trays may encounter insurmountable space constraints during construction, or require cutting, welding, and other processing according to actual site conditions, which is time-consuming, labor-intensive, and inefficient. In addition, as the number of cables increases, the original fixed-size cable trays can hardly meet the ever-changing needs, and the installation and maintenance of cable trays are also relatively difficult.

[0004] Chinese Utility Model Patent Publication No. CN 207303887 U discloses a cable tray support with bidirectional adjustable installation height and width. This support features L-shaped connecting pieces at the connection points of the uprights and crossarms on one or both sides. The L-shaped connecting pieces are connected to the uprights and crossarms via bolts installed in oblong holes. Adjusting the height and width of the bolts on the connecting pieces within the oblong holes on the uprights and crossarms allows for adjustment of the crossarm's height and width. This cleverly solves the problem of insufficient horizontal length of the crossarm due to inadequate spacing between the cable tray and vertical beams and pipes, minor collisions, and limited upright installation positions, which hinders rapid installation. This effectively avoids reordering, delays in construction and installation, reduces construction costs, and improves construction and production efficiency. This utility model allows for vertical adjustment of the crossarm's installation height based on the distance between the cable tray and the bottom of the beam and the pipe, and horizontal adjustment of the crossarm's installation width based on the actual distance between the two side columns, achieving flexible bidirectional adjustment on-site according to the actual distance. However, this cable tray support with bidirectional adjustable installation height and width requires workers to fix the connecting pieces with bolts when adjusting the height and width positions, and finally connect the columns and crossarms with multiple bolts. Therefore, when adjusting the cable tray support, workers need to fix the bolts multiple times, making the adjustment process cumbersome and inefficient. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an adjustable cable tray mounting bracket, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by this utility model is: an adjustable cable tray mounting bracket, including a connecting plate, a support plate, and a first cable tray clamp and a second cable tray clamp located on the top of the support plate. The support plate has a sliding groove at one end near the connecting plate. A bidirectional screw rod is rotatably mounted inside the sliding groove and is mounted on an adjusting rod. A second torsion plate is fixedly mounted at one end of the bidirectional screw rod. A slider is threaded on the outer surface of the bidirectional screw rod. An installation groove is provided at the end of the slider away from the support plate. A locking screw is provided at the end of the slider near the adjusting rod. A cable tray body is mounted on the top of the support plate. Multiple limiting holes are equidistantly provided on the side of the cable tray body.

[0007] Preferably, a plug is fixedly installed at one end of the first cable tray clamp near the cable tray body, and a rubber pad is provided at one end of the second cable tray clamp near the cable tray body, and the plug can be inserted into the limiting hole.

[0008] Through the above technical solution, and by designing the first cable tray clamp and the second cable tray clamp with different functions, the user can select the first cable tray clamp or the second cable tray clamp according to the condition of the cable tray body. When a limit hole is opened on the side of the cable tray body, the first cable tray clamp can be used. At this time, the plug can be inserted into the limit hole, which can strengthen the fixation of the cable tray body. When the cable tray body does not have a limit hole, it can be replaced with the second cable tray clamp. The rubber pad can reduce the wear on the outside of the cable tray body, and the rubber material of the rubber pad has a certain shock absorption function, which improves the applicability of the device.

[0009] Preferably, both the first cable tray clamp and the second cable tray clamp are plugged into the mounting groove, and the slider is fixed to the first cable tray clamp and the second cable tray clamp by locking screws.

[0010] The above technical solution, with the design that both the first and second cable tray clamps are plugged into the mounting groove, allows workers to quickly replace the first and second cable tray clamps. By replacing the first and second cable tray clamps with different functions according to different models of cable tray bodies, the protection of the cable tray body is improved, thereby extending the service life of the cable tray body.

[0011] Preferably, a bevel gear one is rotatably mounted at the top center of the connecting plate. A torsion disc one, which is rotatably connected to the connecting plate, is provided at one end of the bevel gear one near the cable tray body. Bevel gears two are meshed on both sides of the bevel gear one. A transmission rod is fixedly mounted at the end of the bevel gear two away from the bevel gear one. A bevel gear three is fixedly mounted at the end of the transmission rod away from the bevel gear two. A fixing plate supporting bevel gears one and three is fixedly mounted on the top of the inner side of the connecting plate. A bevel gear four is meshed on the side of the bevel gear three away from the bevel gear two. A threaded rod is fixedly mounted on the bottom of the bevel gear four. An adjusting rod is threaded on the outer surface of the threaded rod away from the connecting plate.

[0012] Through the above technical solution, by setting the meshing installation of bevel gear one and bevel gear two, it is convenient for the operator to rotate both sets of bevel gear two at the same time when rotating the torsion disc one. This allows the operator to adjust the height of the bracket, enabling the cable tray body to be quickly adjusted according to installation requirements, and has high compatibility.

[0013] Preferably, the slider and the groove are slidably connected, and the slider is provided in two identical sets, with the two sets of sliders located at both ends of the bidirectional screw.

[0014] The above technical solution, through the sliding connection design of the slider and the groove, and by installing two sets of sliders at both ends of the bidirectional screw, allows the operator to clamp cable tray bodies of different widths by rotating the second torsion plate, thereby improving the stability of the cable tray body.

[0015] Preferably, the bevel gear three, bevel gear four, and threaded rod are all provided in two identical sets, and the two sets of bevel gear three, bevel gear four, and threaded rod are symmetrically distributed on the connecting plate.

[0016] Through the above technical solution, the operator rotates the first torsion disc to drive the first bevel gear to rotate, which in turn drives the two sets of second bevel gears to rotate. The meshing connection between the second and third bevel gears enables the rotation of the third bevel gear, which in turn drives the fourth bevel gear to rotate, thereby driving the threaded rod to rotate. Through the threaded connection between the threaded rod and the adjusting rod, the adjusting rod can be driven to move vertically up and down, realizing the height adjustment of the support plate. This allows the height position of the cable tray body to be quickly adjusted according to installation requirements, and has high compatibility.

[0017] Compared with the prior art, the present invention provides an adjustable cable tray mounting bracket, which has the following advantages:

[0018] 1. This adjustable cable tray mounting bracket features a sliding connection between the slider and the groove. Two sets of sliders are installed at both ends of a bidirectional screw, allowing workers to clamp cable trays of different widths by rotating the second toggle disc during installation.

[0019] 2. This adjustable cable tray mounting bracket, through the design of the first cable tray clamp and the second cable tray clamp with different functions, allows the user to select the first or second cable tray clamp according to the condition of the cable tray body. When the cable tray body has a limit hole on the side, the first cable tray clamp can be used, and the plug can be inserted into the limit hole to strengthen the fixation of the cable tray body. When the cable tray body does not have a limit hole, the second cable tray clamp can be used. The rubber pad can reduce the wear on the outside of the cable tray body, and the rubber material of the rubber pad has a certain shock absorption function, which improves the applicability of the device.

[0020] 3. When the height of the support plate needs to be adjusted, the operator rotates the first torsion disc to drive the first bevel gear to rotate, which in turn drives the two sets of second bevel gears to rotate. The meshing connection between the second and third bevel gears enables the rotation of the third bevel gear, which in turn drives the fourth bevel gear to rotate, thereby driving the threaded rod to rotate. The threaded connection between the threaded rod and the adjusting rod allows the adjusting rod to move vertically up and down, thus achieving height adjustment of the support plate. This allows the height of the cable tray to be quickly adjusted according to installation requirements, providing high compatibility. Attached Figure Description

At this time, the plug 19 can be just inserted into the limiting hole 23, which can strengthen the fixation of the cable tray body 22.

[0032] Specifically, the first cable tray clamp 17 and the mounting groove 16 are plug-in installed, and the slider 15 is connected to the first cable tray clamp 17 by the locking screw 21. The advantage of the plug-in installation design of the first cable tray clamp 17 and the mounting groove 16 is that the first cable tray clamp 17 can be quickly installed and removed, and the first cable tray clamp 17 can be quickly fixed by the locking screw 21. It also facilitates the quick disassembly of the first cable tray clamp 17 by the staff later, thereby improving the installation efficiency.

[0033] Example 2:

[0034] like Figure 1-6 As shown, as an improvement on the previous embodiment, when workers need to use cable tray clamps without protrusions for installation, an adjustable cable tray mounting bracket includes a connecting plate 1, a support plate 11, and a first cable tray clamp 17 and a second cable tray clamp 18 located on the top of the support plate 11. A sliding groove 12 is provided at one end of the support plate 11 near the connecting plate 1. A bidirectional screw 13 is provided inside the sliding groove 12 and is rotatably mounted with an adjusting rod 10. A torsion disc 14 is fixedly installed at one end of the bidirectional screw 13. A slider 15 is threaded on the outer surface of the bidirectional screw 13. An installation groove 16 is provided at one end of the slider 15 away from the support plate 11. A locking screw 21 is provided at one end of the slider 15 near the adjusting rod 10. A cable tray body 22 is installed on the top of the support plate 11.

It also facilitates the quick disassembly of the second cable tray clamp 18 by the staff later, thereby improving the installation efficiency.

[0037] Example 3:

[0038] like Figure 1-6As shown, based on Embodiments 1 and 2, to further facilitate the height adjustment of the support plate 11, specifically, a bevel gear 12 is rotatably mounted at the center of the top of the connecting plate 1. A torsion disc 3, rotatably connected to the connecting plate 1, is provided at one end of the bevel gear 12 near the cable tray body 22. Bevel gears 24 are meshed on both sides of the bevel gear 12. A transmission rod 6 is fixedly mounted at the end of the bevel gear 24 away from the bevel gear 12. A bevel gear 3 7 is fixedly mounted at the end of the transmission rod 6 away from the bevel gear 24. Supporting bevel gears 12 and 3 are fixedly mounted on the top of the inner side of the connecting plate 1. The fixed plate 5 of 7 has a bevel gear 4 connected to the bevel gear 3 7 on the side away from the bevel gear 2 4. A threaded rod 9 is fixedly installed at the bottom of the bevel gear 4 8. An adjusting rod 10 is threaded on the outer surface of the threaded rod 9 on the side away from the connecting plate 1. The advantage is that by setting the bevel gear 1 2 and bevel gear 2 4 to mesh, it is convenient for the operator to rotate the two sets of bevel gear 2 4 at the same time when rotating the torsion disc 1 3. This makes it convenient for the operator to adjust the height of the bracket, so that the height position of the cable tray body 22 can be quickly adjusted according to the installation requirements, and has high compatibility.

[0039] Specifically, the slider 15 and the slide groove 12 are slidably connected. Two identical sets of sliders 15 are provided, with the two sets of sliders 15 located at both ends of the bidirectional screw 13. The advantage is that by designing the slider 15 and the slide groove 12 to be slidably connected, and by installing the two sets of sliders 15 at both ends of the bidirectional screw 13, it is convenient for the operator to rotate the torsion disc 14 to make the two sets of sliders 15 move in opposite directions, thereby clamping the cable tray body 22 with different widths, thus improving the stability of the cable tray body 22.

[0040] Specifically, bevel gear 3 (7), bevel gear 4 (8), and threaded rod 9 are all provided in two identical sets. The two sets of bevel gear 3 (7), bevel gear 4 (8), and threaded rod 9 are symmetrically distributed on the connecting plate 1. The advantage is that the operator can rotate bevel gear 1 (2) by rotating the torsion disc 1 (3), which in turn drives the two sets of bevel gear 2 (4) to rotate. The rotation of bevel gear 3 (7) is achieved through the meshing connection between bevel gear 2 (4) and bevel gear 3 (7). The rotation of bevel gear 3 (7) drives the rotation of bevel gear 4 (8), which in turn drives the threaded rod 9 to rotate. The threaded connection between the threaded rod 9 and the adjusting rod 10 allows the adjusting rod 10 to move vertically up and down, thereby adjusting the height of the support plate 11. This allows the height of the cable tray body 22 to be quickly adjusted according to installation requirements, providing high compatibility.

[0041] Working Principle: During use, the operator first secures the connecting plate 1 to the ceiling using bolts. Then, the slider 15 is slidably connected to the slide groove 12, and two sets of sliders 15 are installed at both ends of the bidirectional screw 13. This allows the operator to clamp cable tray bodies 22 of different widths by rotating the torsion disc 14 during installation. Furthermore, the first cable tray clamp 17 and the second cable tray clamp 18 are designed for plug-in installation into the mounting groove 16, enabling quick installation of both. This facilitates the replacement of the first cable tray clamp 17 and the second cable tray clamp 18 with different functions depending on the cable tray body 22 model. The different functions of the first cable tray clamp 17 and the second cable tray clamp 18 allow the user to select either the first cable tray clamp 17 or the second cable tray clamp 18 based on the cable tray body 22. When a limit hole 23 is provided on the side of the cable tray body 22, it is possible to... Using the first cable tray clamp 17, the insert block 19 can be inserted into the limiting hole 23, which can strengthen the fixation of the cable tray body 22. When the cable tray body 22 does not have the limiting hole 23, it can be replaced with the second cable tray clamp 18. The rubber pad 20 can reduce the wear on the outside of the cable tray body 22, and the rubber pad 20 has a certain shock absorption function, which improves the applicability of the device. When the height of the support plate 11 needs to be adjusted, the operator rotates the first torsion disc 3 to drive the first bevel gear 2 to rotate, which in turn drives the two sets of second bevel gears 4 to rotate. The meshing connection between the second bevel gear 4 and the third bevel gear 7 realizes the rotation of the third bevel gear 7. The rotation of the third bevel gear 7 realizes the rotation of the fourth bevel gear 8, which drives the threaded rod 9 to rotate. The threaded connection between the threaded rod 9 and the adjusting rod 10 can drive the adjusting rod 10 to move vertically up and down, realizing the height adjustment of the support plate 11. This allows the height position of the cable tray body 22 to be quickly adjusted according to the installation requirements, which has high compatibility.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
