Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a device for preventing cable tray accessories from bending and deforming. Background Technology

[0002] Cable trays are made of thin steel plates and have a certain limit to their load-bearing capacity. Otherwise, the trays will deform severely due to overloading, affecting their appearance and the safe operation of the cables. The load-bearing capacity of cable trays is usually represented by their load characteristic curve. As can be seen from the load curve, the load-bearing capacity of a cable tray is a quantity related to the tray specifications and support distance. For the same support distance and bending deformation, the cable tray with a larger side height has a larger load-bearing capacity, while the cable tray with a smaller height has a smaller load-bearing capacity. In addition, when the load-bearing capacity is the same, for cable trays of the same specifications, the bending deformation is smaller for those with a smaller support distance than for those with a larger support distance.

[0003] In the prior art, existing cable trays are usually composed of a base plate and cable trays on both sides. When the cable tray is subjected to gravity, the cable trays on both sides are easily deformed, which leads to deformation of the base plate and shortens the service life of the cable tray. In addition, the cable tray is usually connected to the cable trays on both sides by fixed steel plates. The fixed steel plates are not elastic, and under the action of gravity, the fixed steel plates and the cable trays on both sides are prone to deformation. Therefore, this application proposes a device to prevent bending deformation of cable tray accessories to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies, such as cable trays typically consisting of a base plate and cable trays on both sides, where the cable trays are easily deformed under pressure when subjected to gravity, leading to deformation of the base plate and shortening the service life of the cable tray. Furthermore, cable trays are usually connected to the cable trays on both sides by fixed steel plates, which lack elasticity and are prone to deformation under gravity. Therefore, this utility model proposes a device to prevent bending deformation of cable tray accessories.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for preventing bending deformation of cable tray accessories includes a U-shaped frame, and the cable tray further includes:

[0007] A cover, which is installed on the top of the U-shaped frame;

[0008] Multiple buffer springs are provided, and the top ends of the multiple buffer springs are fixedly installed at the bottom of the U-shaped frame.

[0009] A buffer plate, the top of which is fixedly installed to the bottom end of a plurality of buffer springs;

[0010] The stabilizing rods are provided in four parts, and the four stabilizing rods are respectively fixedly installed on the front and rear sides of the cover. The stabilizing rods are provided with slots.

[0011] The four stabilizing rings are respectively fixedly installed on the front and rear sides of the U-shaped frame, and the stabilizing rings are slidably sleeved on the corresponding stabilizing rods.

[0012] The mounting components are configured in two parts, which are respectively located on the front and rear sides of the U-shaped frame, and each mounting component mates with a corresponding slot.

[0013] As a preferred embodiment of this utility model, slots are provided at both ends of the bottom of the cover, and the top ends of the U-shaped frame can be detached and inserted into the two slots respectively.

[0014] As a preferred embodiment of this utility model, multiple positioning rods are fixedly installed on the buffer plate, and multiple positioning sleeves are fixedly installed on the outer side of the U-shaped frame, with the positioning sleeves slidably fitted onto the corresponding positioning rods.

[0015] As a preferred embodiment of this utility model, multiple reinforcing plates are fixedly installed on the inner wall of the U-shaped frame.

[0016] In a preferred embodiment of this utility model, the installation assembly includes two sliding rods, two locking rods, a return spring, a limiting block, a screw, and a nut. The two sliding rods are slidably connected to one side of the U-shaped frame. The ends of the two locking rods that are close to each other are fixedly installed on the two sliding rods, while the ends that are far apart can be disengaged and inserted into two locking slots. The left and right ends of the return spring are fixedly installed on the tops of the two sliding rods. The limiting block is slidably connected to one side of the U-shaped frame, with its top two sides slidably contacting the two sliding rods. The top of the screw is rotatably connected to the bottom of the limiting block. The nut is threaded onto the screw and fixedly installed on one side of the U-shaped frame.

[0017] As a preferred embodiment of this utility model, the front and rear sides of the U-shaped frame are provided with sliding grooves, and the number of sliding grooves is four. One end of the sliding rod is slidably connected in the corresponding sliding groove.

[0018] Beneficial effects:

[0019] 1. By setting up a buffer plate and multiple buffer springs in cooperation, the U-shaped frame can be stably buffered and protected when it is under stress, which can prevent the U-shaped frame from deforming under stress. At the same time, after the cover is installed on the U-shaped frame and the stabilizing rod and stabilizing ring are inserted, the cover can be restricted from sliding laterally on the U-shaped frame, thus improving the installation stability between the U-shaped frame and the cover.

[0020] 2. By rotating the screw and engaging the threaded connection between the screw and the nut, the limiting block can be moved upward and squeezed to move the two sliding rods away from each other. This will cause the two locking rods to move away from each other and be inserted into the two locking slots. This will enable the stable fixing of the stabilizing rod after installation between the cover and the U-shaped frame, thereby improving the installation stability between the cover and the U-shaped frame.

[0021] This utility model achieves a stable connection between the U-shaped frame and the cover through a simple structure. The structural design of the U-shaped frame and the cover ensures high overall stability of the cable tray. At the same time, it can provide stable buffer protection for the U-shaped frame when it is under stress, thus preventing deformation of the U-shaped frame and making it highly practical.

[0030] Cover 7 is installed on the top of the U-shaped frame 1;

[0031] Multiple buffer springs 2 are provided, and the top ends of the multiple buffer springs 2 are fixedly installed at the bottom of the U-shaped frame 1;

[0032] The top of the buffer plate 3 is fixedly installed to the bottom of the multiple buffer springs 2 respectively;

[0033] There are four stabilizing rods 9, which are fixedly installed on the front and rear sides of the cover 7 respectively. The stabilizing rods 9 are provided with slots 10.

[0034] Four stabilizing rings 11 are provided. The four stabilizing rings 11 are fixedly installed on the front and rear sides of the U-shaped frame 1, and the stabilizing rings 11 are slidably sleeved on the corresponding stabilizing rods 9.

[0035] The mounting components are configured in two parts, with the two mounting components respectively located on the front and rear sides of the U-shaped frame 1, and each mounting component mates with a corresponding slot 10.

[0036] With the above structure, by setting the buffer plate 3 and multiple buffer springs 2 together, the U-shaped frame 1 can be stably buffered and protected when it is under force, which can prevent the U-shaped frame 1 from deforming under force. At the same time, after the cover 7 is installed on the U-shaped frame 1 and the stabilizing rod 9 is inserted into the stabilizing ring 11, the cover 7 can be restricted from sliding laterally on the U-shaped frame 1, thereby improving the installation stability between the U-shaped frame 1 and the cover 7.

[0037] As a preferred embodiment of this utility model, slots 8 are provided at both ends of the bottom of the cover 7. The top ends of the U-shaped frame 1 can be detached and inserted into the two slots 8 respectively. By providing slots 8, the top ends of the U-shaped frame 1 and the cover 7 can be stably inserted and limited, making the connection between the cover 7 and the U-shaped frame 1 more stable.

[0038] As a preferred embodiment of this utility model, a plurality of positioning rods 4 are fixedly installed on the buffer plate 3, and a plurality of positioning sleeves 5 are fixedly installed on the outer side of the U-shaped frame 1. The positioning sleeves 5 are slidably sleeved on the corresponding positioning rods 4. By setting the insertion limit between the positioning rods 4 and the positioning sleeves 5, the U-shaped frame 1 and the buffer plate 3 can be stably slidably limited.

[0039] As a preferred embodiment of this utility model, multiple reinforcing plates 6 are fixedly installed on the inner wall of the U-shaped frame 1. By setting the reinforcing plates 6, the overall stability of the U-shaped frame 1 can be improved.

[0040] In a preferred embodiment of this utility model, the mounting assembly includes two sliding rods 13, two locking rods 14, a return spring 15, a limiting block 16, a screw 17, and a nut 18. Both sliding rods 13 are slidably connected to one side of the U-shaped frame 1. The ends of the two locking rods 14 that are close to each other are fixedly mounted on the two sliding rods 13, while the ends that are far apart can be disengaged and inserted into two locking slots 10. The left and right ends of the return spring 15 are fixedly mounted on the tops of the two sliding rods 13. The limiting block 16 is slidably connected to one side of the U-shaped frame 1, and the top two sides of the limiting block 16 are respectively connected to the two sliding rods. 13 Sliding contact, the top of the screw 17 is rotatably connected to the bottom of the limiting block 16, and the nut 18 is threaded onto the screw 17. The nut 18 is fixedly installed on one side of the U-shaped frame 1. By rotating the screw 17 and through the threaded connection between the screw 17 and the nut 18, the limiting block 16 can be moved upward and squeezed to move the two sliding rods 13 away from each other. At this time, the two locking rods 14 can be moved away from each other and inserted into the two locking slots 10. At this time, after the frame cover 7 is installed between the U-shaped frame 1, the stabilizing rod 9 can be stably fixed, thereby improving the installation stability between the frame cover 7 and the U-shaped frame 1.

[0041] As a preferred embodiment of this utility model, the front and rear sides of the U-shaped frame 1 are provided with sliding grooves 12, and there are four sliding grooves 12. One end of the sliding rod 13 is slidably connected in the corresponding sliding groove 12. By providing sliding grooves 12, the sliding rod 13 can be stably limited and supported.

[0042] The working principle of this utility model is as follows: In use, the cooperation between the buffer plate 3 and multiple buffer springs 2 provides stable buffering protection for the U-shaped frame 1 when it is under stress, preventing deformation. Simultaneously, after the cover 7 is installed on the U-shaped frame 1, and the stabilizing rod 9 is inserted into the stabilizing ring 11, the lateral sliding of the cover 7 on the U-shaped frame 1 is restricted, improving the installation stability between the U-shaped frame 1 and the cover 7. The slots 8 allow for connection between the top two ends of the U-shaped frame 1 and the frame... The cover 7 is stably inserted and limited, making the connection between the cover 7 and the U-shaped frame 1 more secure. In addition, by rotating the screw 17 and through the threaded connection between the screw 17 and the nut 18, the limiting block 16 can be moved upward and squeeze the two sliding rods 13 away from each other. At this time, the two locking rods 14 can be moved away from each other and inserted into the two locking slots 10. At this time, after the cover 7 and the U-shaped frame 1 are installed, the stabilizing rod 9 can be stably fixed, thereby improving the installation stability between the cover 7 and the U-shaped frame 1.
