Description

Technical Field

[0001] This utility model relates to the field of trough-type cable trays, and particularly to pressure-resistant components and trough-type cable trays. Background Technology

[0002] Cable trays, also known as trough-type cable trays, are fully enclosed cable trays widely used for laying computer cables, communication cables, thermocouple cables, and other control cables for highly sensitive systems. These trays are equipped with covers and use a minimal number of connecting bolts, offering advantages such as cost-effectiveness, high strength, lightweight design, and high corrosion resistance. Experts have hailed them as the epitome of economical and high-strength cable trays. However, with the rapid development of modern power and communication systems, the requirements for the compressive strength and stability of cable trays are becoming increasingly stringent. Traditional trough-type cable trays may deform or be damaged under significant pressure, affecting the safe operation of cables. Therefore, developing a trough-type cable tray with higher compressive strength is particularly important. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the aforementioned problems in the prior art, this utility model provides a pressure-resistant component and a trough-type cable tray.

[0005] (II) Technical Solution

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by this utility model include:

[0007] A pressure-resistant component includes a base plate, a pressure-bearing plate, a support rod, a shock-absorbing and pressure-resistant component, and a fixing clamp;

[0008] Two support rods are provided, which are symmetrically arranged on the base plate.

[0009] The pressure plate has guide holes corresponding to the support rod. The pressure plate is slidably mounted on the support rod through the guide holes and is positioned above the base plate.

[0010] The shock-absorbing and pressure-resistant components are provided in two sets, which are symmetrically arranged on the base plate. The shock-absorbing and pressure-resistant components include a base, a first connecting rod, a second connecting rod, a movable rod, a connecting rod, and a damping spring shock absorber.

[0011] The base is fixed to the bottom plate;

[0012] One end of the first connecting rod and the second connecting rod are both hinged to the base, and the first connecting rod and the second connecting rod are arranged parallel to each other. The ends of the first connecting rod and the second connecting rod away from the base are rotatably connected to the movable rod.

[0013] One end of the connecting rod is rotatably connected to the movable rod, and the other end of the connecting rod is fixedly connected to the pressure plate;

[0014] The fixing clamp is installed on the pressure plate and is used to fix the trough-type cable tray.

[0015] Preferably, the fixing clamps are provided in two sets, which are arranged symmetrically on the surface of the pressure plate.

[0016] Preferably, the fixing fixture includes a guide rail, a slider, and an L-shaped fixing block;

[0017] The guide rail is fixed to the surface of the pressure plate;

[0018] The slider is slidably mounted on the guide rail and fastened to the guide rail by bolts;

[0019] The vertical part of the L-shaped fixing block is fixedly connected to the slider at one end.

[0021] (III) Beneficial Effects

[0022] The beneficial effects of this utility model are as follows: By adopting the above technical solution, the trough-type cable tray is installed on the pressure plate by fixing clamps. When the pressure plate is subjected to pressure, the first and second connecting rods simultaneously generate downward rotational fluctuations. The damping spring shock absorber can effectively absorb the kinetic energy of the first and second connecting rods during rotation, thereby playing the role of longitudinal wave damping and pressure resistance. At the same time, the base plate also shares the force applied to the pressure plate by the cable, increasing the support stability. The heat dissipation positioning holes on the trough-type cable tray are not only used to achieve heat dissipation, but can also be used with positioning rods to achieve fixed positioning, improving the fixed stability of the cable tray body.

[0033] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Please refer to Figures 1 to 3 This utility model provides a pressure-resistant component 1, including a base plate 11, a pressure-bearing plate 14, a support rod 13, a shock-absorbing and pressure-resistant component 12, and a fixing clamp 3;

[0035] Two support rods 13 are provided, which are symmetrically arranged on the base plate 11 from left to right;

[0036] The pressure plate 14 has guide holes corresponding to the support rod 13. The pressure plate 14 is slidably installed on the support rod 13 through the guide holes and is positioned above the base plate 11.

[0037] Two sets of shock-absorbing and pressure-resistant components 12 are provided and are symmetrically arranged on the base plate 11. The shock-absorbing and pressure-resistant components 12 include a base 121, a first connecting rod 122, a second connecting rod 123, a movable rod 125, a connecting rod 126, and a damping spring shock absorber 124.

[0038] The base 121 is fixed on the base plate 11;

[0039] One end of the first link 122 and the second link 123 are both hinged to the base 121, and the first link 122 and the second link 123 are arranged parallel to each other. The ends of the first link 122 and the second link 123 away from the base 121 are rotatably connected to the movable rod 125.

[0040] One end of the connecting rod 126 is rotatably connected to the movable rod 125, and the other end of the connecting rod 126 is fixedly connected to the pressure plate 14.

[0041] The fixing clamp 3 is installed on the pressure plate 14 to fix the trough-type cable tray 2;

[0042] In use, the trough-type cable tray 2 is installed on the pressure plate 14 by the fixing clamp 3. When the pressure plate 14 is subjected to pressure, the first connecting rod 122 and the second connecting rod 123 simultaneously generate downward rotational fluctuations. The damping spring shock absorber 124 can effectively absorb the kinetic energy of the first connecting rod 122 and the second connecting rod 123 during rotation, thereby playing the role of longitudinal wave damping and pressure resistance. At the same time, the base plate 11 also shares the force applied to the pressure plate 14 by the cable, increasing the support stability.

[0043] In this embodiment, two sets of fixing clamps 3 are provided, which are symmetrically arranged on the surface of the pressure plate 14. The fixing clamps 3 include a guide rail 31, a slider 32 and an L-shaped fixing block 33.

[0044] Guide rail 31 is fixed to the pressure plate 14.

[0045] The slider 32 is slidably mounted on the guide rail 31 and fastened to the guide rail 31 by bolts;

[0046] The vertical part of the L-shaped fixing block 33 is fixedly connected to the slider 32 at one end. The vertical part of the L-shaped fixing block 33 is provided with a positioning rod on the side near the trough-type cable tray 2. The horizontal part of the L-shaped fixing block 33 is used to fix it to the top of the trough-type cable tray 2.

[0047] In use, by sliding the slider 32, the L-shaped fixing block 33 is pressed tightly against one side of the trough-type cable tray 2, and then the bolts are tightened to achieve the installation and fixation of the trough-type cable tray 2 after sliding.

[0048] A trough-type cable tray 2 includes a cable tray body 21 and a cover body 22. The cover body 22 covers the cable tray body 21. Heat dissipation positioning holes 23 corresponding to positioning rods are opened on both sides of the trough wall of the cable tray body 21. The heat dissipation positioning holes 23 are not only used to achieve heat dissipation, but also to achieve fixed positioning in conjunction with the positioning rods, thereby improving the fixed stability of the cable tray body 21.

[0049] The working principle of this utility model is as follows:

[0050] The trough-type cable tray 2 is installed on the pressure plate 14 using the fixing clamp 3. When the pressure plate 14 is subjected to pressure, the first connecting rod 122 and the second connecting rod 123 simultaneously generate downward rotational fluctuations. The damping spring shock absorber 124 can effectively absorb the kinetic energy of the first connecting rod 122 and the second connecting rod 123 during rotation, thereby playing the role of longitudinal wave damping and pressure resistance. At the same time, the base plate 11 also shares the force applied to the pressure plate 14 by the cable, increasing the support stability. The heat dissipation positioning holes 23 on the trough-type cable tray 2 are not only used to achieve heat dissipation, but can also be used with the positioning rod to achieve fixed positioning, improving the fixed stability of the cable tray body 21.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
