Description

Technical Field

[0001] This utility model relates to a suspension structure for cable trays, specifically a suspension structure for high-strength lightweight cable trays. Background Technology

[0002] Cable trays are classified into trough type, tray type, ladder type, and mesh type structures. They are composed of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building (structure) and pipe gallery supports. They should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors are also classified as such.

[0003] The suspension structure is the load-bearing part of the cable tray. The cable tray itself needs to have a certain strength to bear the weight of various cables. The current suspension structure of cable trays is usually composed of components such as hangers, nuts, washers, and hangers. The hangers are generally metal rods with threads on their outer perimeter. The upper end of the hanger is fixed to the beams or slabs of the building structure by expansion bolts, and the lower end of the hanger is connected to the cable tray. Some trapezoidal cable trays have different heights in each section, and the height of the corresponding suspension structure also needs to be adjusted. The current adjustment method is to rotate the nuts under the hanger to move the hanger on the hanger. However, in the process of height adjustment, a wrench is needed to turn the two nuts under the hanger one by one. Traditional unilateral adjustment is prone to causing the hanger to tilt. Utility Model Content

[0004] The purpose of this invention is to provide a suspension structure for a high-strength, lightweight cable tray to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A suspension structure for a high-strength, lightweight cable tray includes two symmetrically designed suspension supports and a suspension hanger. Each suspension support has a limiting groove on one side, and the suspension hanger slides between the limiting grooves of the two suspension supports. Each suspension support also has a positioning opening on one side. The top of the suspension hanger includes the cable tray body and two bolt fixing plates for securing the cable tray body. The suspension hanger contains a pressing adjustment mechanism and a connecting rod limiting mechanism located on one side of the pressing adjustment mechanism. The connecting rod limiting mechanism cooperates with a sliding support mechanism located within the suspension hanger.

[0007] The suspension structure of the high-strength lightweight cable tray as described above: the sliding support mechanism includes two sliding frames symmetrically slidably installed in the suspension bracket and a positioning block connected to one side of the sliding frame, the positioning block being plugged into the positioning opening.

[0008] The suspension structure of the high-strength lightweight cable tray as described above: the sliding support mechanism further includes a sliding cavity opened at one end of the sliding frame and a sliding block sliding on the sliding cavity, and a column is provided on the sliding block.

[0009] The suspension structure of the high-strength lightweight cable tray as described above: the pressing adjustment mechanism includes a cylinder disposed in the suspension bracket and a button slidably mounted on the outside of the cylinder, the button being provided with a connecting plate.

[0010] The suspension structure of the high-strength lightweight cable tray as described above: the pressing and adjusting mechanism further includes two connecting arms symmetrically connected to the connecting plate and a first limiting groove opened on the connecting arm, the first limiting groove being used to limit the position of the column.

[0011] The suspension structure of the high-strength lightweight cable tray described above includes a linkage limiting mechanism comprising two guide frames symmetrically arranged within the suspension bracket and a second limiting groove formed on the guide frames, the second limiting groove being used to limit the position of the column.

[0012] The suspension structure of the high-strength lightweight cable tray as described above: the suspension bracket is equipped with two sets of return springs, and the two sets of return springs are respectively connected to two sliding brackets.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The system employs a linkage height adjustment mechanism, with a push-button linkage component integrated at the bottom of the hanger. When the bottom button is pressed, the locking blocks on both sides of the hanger retract inward, allowing for flexible height adjustment and free raising and lowering of the hanger. After releasing the button, the return spring pushes the locking blocks to automatically extend outward, precisely engaging with the corresponding height positioning opening to form a stable mechanical lock. The push-button linkage design enables the simultaneous opening and closing of the locking blocks at both ends, avoiding the risk of hanger tilting caused by traditional single-sided adjustment and ensuring installation accuracy and stability.

[0015] This invention also allows for flexible adjustment of the hanger height by using a short-stroke button press to move the two side blocks a long stroke. In actual operation, construction personnel do not need to use large tools or perform complicated procedures; they can simply press the button to quickly adjust the hanger height, which greatly improves installation and debugging efficiency and saves manpower and time costs.

[0025] 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.

[0026] Please see Figures 1-8As an embodiment of this utility model, the suspension structure of the high-strength lightweight cable tray includes two symmetrically designed suspension brackets 1 and suspension hangers 4. A limiting groove 2 is provided on one side of each suspension bracket 1, and the suspension hanger 4 slides between the limiting grooves 2 of the two suspension brackets 1. A positioning opening 3 is provided on one side of each suspension bracket 1. A cable tray body 6 and two bolt fixing plates 5 for fixing the cable tray body 6 are provided on the top of the suspension hanger 4. A pressing adjustment mechanism and a connecting rod limiting mechanism are provided on one side of the pressing adjustment mechanism. The connecting rod limiting mechanism cooperates with a sliding support mechanism provided in the suspension hanger 4.

[0027] In this embodiment, in the initial state, the cable tray body 6 is fixed between two bolt fixing plates 5 at the top of the suspension bracket 4. Then, when it is necessary to adjust the suspension height, the locking blocks on both sides of the suspension bracket 4 are retracted inward by pressing the adjustment mechanism and the linkage linkage limiting mechanism. At this time, the height of the suspension bracket 4 can be flexibly adjusted. When the pressing adjustment mechanism is released, the locking blocks automatically extend outward and accurately lock into the positioning opening 3 of the corresponding height, forming a stable mechanical lock. This achieves synchronous opening and closing of the locking blocks at both ends, avoiding the risk of bracket tilting caused by traditional single-sided adjustment, and ensuring installation accuracy and stability.

[0028] As a further embodiment of this utility model, the sliding support mechanism includes two sliding frames 9 symmetrically slidably installed in the suspension bracket 4 and a positioning block 10 connected to one side of the sliding frame 9. The positioning block 10 is plugged into the positioning opening 3.

[0029] In this embodiment, sliding frames 9 are slidably mounted on both ends of the suspension bracket 4, and a positioning block 10 is fixed to one end of the sliding frame 9. Through the cooperation of the positioning block 10 and the positioning opening 3, the suspension bracket 4 can be suspended and fixed at this height position.

[0030] As a further embodiment of the present invention, the sliding support mechanism further includes a sliding cavity 11 formed at one end of the sliding frame 9 and a sliding block 12 sliding on the sliding cavity 11, wherein a column 13 is provided on the sliding block 12.

[0031] In this embodiment, the sliding block 12 slides on the sliding cavity 11 at one end of the sliding frame 9, and the column 13 is disposed on the sliding block 12.

[0032] As a further embodiment of this utility model, the pressing adjustment mechanism includes a cylinder 7 disposed within the suspension bracket 4 and a button 8 slidably mounted on the outside of the cylinder 7, wherein a connecting plate 16 is provided on the button 8.

[0033] In this embodiment, the cylinder 7 is fixed inside the suspension bracket 4, the button 8 slides around the outer periphery of the cylinder 7, and the connecting plate 16 is connected to the outer side of the button 8.

[0034] As a further embodiment of this utility model, the pressing adjustment mechanism also includes two connecting arms 17 symmetrically connected to the connecting plate 16 and a first limiting groove 18 formed on the connecting arms 17, the first limiting groove 18 being used to limit the position of the column 13.

[0035] In this embodiment, two connecting arms 17 are respectively connected to the two ends of the connecting disk 16, and the column 13 slides in the first limiting groove 18 of the connecting arm 17.

[0036] As a further embodiment of this utility model, the linkage limiting mechanism includes two guide frames 14 symmetrically arranged in the suspension bracket 4 and a second limiting groove 15 opened on the guide frames 14. The second limiting groove 15 is used to limit the position of the column 13.

[0037] In this embodiment, the guide frame 14 is designed at an angle, and the second limiting groove 15 limits the movement of the column 13.

[0038] As a further improvement of this utility model, the suspension bracket 4 is provided with two sets of return springs 19, and the two sets of return springs 19 are respectively connected to two sliding brackets 9.

[0039] In this embodiment, when button 8 is pressed, button 8 drives the two connecting arms 17 to move upward through connecting plate 16. At this time, connecting arm 17 applies an upward force to sliding block 12 through column 13. At the same time, guide frame 14 limits the movement direction of sliding block 12, so that sliding block 12 moves towards guide frame 14. Simultaneously, sliding block 12 slides on sliding cavity 11. At this time, sliding block 12 drives sliding frame 9 and positioning block 10 to retract inward. During the inward movement of sliding frame 9, return spring 19 is compressed, realizing the inward retraction of positioning blocks 10 on both sides of suspension bracket 4. This allows short-stroke button 8 to drive the positioning blocks 10 on both sides to move a long stroke, so as to realize the flexible adjustment of bracket height through linkage and coordination of linkage limit mechanism.

[0040] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
