Description

Technical Field

[0001] This application relates to the field of trough-type cable tray technology, and specifically discloses a trough-type cable tray. Background Technology

[0002] Cable trays (cable supports) are a rigid structural system consisting of straight sections, bends, components, supports (arm-type brackets), and hangers of trays or ladders, providing close support for cables. Trough-type cable trays are trough-shaped components bent from a single sheet of steel. Trough-type cable trays can be used for fully enclosed cable laying. They are best suited for laying computer cables, communication cables, thermocouple cables, and control cables for other highly sensitive systems. They offer good shielding against interference and protection for cables in highly corrosive environments.

[0003] Cable trays typically consist of three main parts:

[0004] The trough body: This is the main part of the trough-type cable tray. It is made of a whole steel plate and has a certain depth and enclosure. It is trough-shaped and can effectively protect the cables.

[0005] Cover plate: Matched with the cable tray, it covers the top of the cable tray and plays a role in sealing and protecting it, preventing external dust, debris and other objects from entering the cable tray and causing damage to the cables. At the same time, it can further enhance the protective performance of the cable tray.

[0006] Bends: Used to change the direction of cable trays, allowing them to be laid at different angles and directions to meet actual wiring needs. Common bends include horizontal bends and vertical bends, and their specifications should meet the engineering layout requirements and be compatible with the cable trays.

[0007] The current problem is:

[0008] The connection between the cover plate, bend, and trough is too complex and independent. After the cover plate, bend, and trough are connected, they all rely on their own connection structure to achieve stable installation. They cannot cooperate with each other to assist in stable installation. As a result, the stability of the bend and cover plate may be insufficient, which may lead to the bend and cover plate falling off. In view of this, this utility model provides a trough-type cable tray to solve the above problems. Utility Model Content

[0009] The purpose of this invention is to solve the problem that the traditional cover plate and bend are installed independently on the groove body and cannot help each other to stabilize the installation.

[0010] To achieve the above objectives, this utility model provides the following basic solution:

[0011] A trough-type cable tray includes a trough body, a cover plate, and bends;

[0012] The tank body has several mounting holes evenly distributed on the top of the tank body, and matching holes are also provided on the top of the tank body. The outer side of the tank body has load-bearing holes that communicate with the matching holes.

[0013] The matching cover plate: a number of insertion rods are fixedly connected to the cover plate at the positions corresponding to the mounting holes, and a connecting rod is fixedly connected to the position corresponding to the matching holes. A number of connecting holes are opened on the outer side of the connecting rod.

[0014] The matching bend: both ends of the bend are fixed with a load-bearing plate that can be inserted into the load-bearing hole, and the free end of the load-bearing plate is provided with a pin that can be inserted into the connection hole;

[0015] The pin and the outer periphery of the load-bearing plate are covered with friction pads.

[0016] Furthermore, the groove, cover plate, and bend are all made of the same material, aluminum alloy. Using the same material helps ensure the approximate service life of all three components, as aluminum alloy is lightweight, high-strength, aesthetically pleasing, has good heat dissipation, and strong corrosion resistance.

[0017] Furthermore, the trough is a concave trough. The concave trough is part of the basic shape of the trough-type cable tray, and features low mold-making costs and mature technology.

[0018] Furthermore, the friction pad is a rubber friction pad. The rubber friction pad further enhances the friction, thereby improving the connection stability of the bend and ensuring a stable connection.

[0019] Furthermore, both the load-bearing hole and the matching hole are cylindrical holes, and the mounting hole and the matching hole have the same depth. The inner diameter of the matching hole is larger than that of the mounting hole. Since the matching hole is needed to fit with a bend, its inner diameter is larger than that of the mounting hole. The matching hole is used to install the cover plate, achieving stable installation of the cover plate.

[0020] Furthermore, the width of the cover plate is greater than the width of the groove. This wider cover plate ensures complete coverage of the groove, resulting in a more aesthetically pleasing overall structure.

[0021] Furthermore, the size of the load-bearing hole is larger than the size of the matching hole.

[0022] Furthermore, the pin, which is wrapped with a friction pad, is clearance-fitted with the connecting hole.

[0023] The principle and effect of this solution are as follows:

[0024] 1. Compared with existing technologies, this device has a simple structure and ingenious design. This device still has a trough, bends, and cover plates. However, after the cover plate is connected to the trough, several connection holes are opened on the outside of the connecting rod. The bends are connected through the connection holes and the load-bearing holes. The load-bearing holes ensure the strength of the connection, and the connection holes prevent the cover plate from falling off. The cover plate can only be removed after the bend is removed, thus realizing a certain self-locking function of the cover plate. This maximizes the sealing of the trough-type cable tray and solves the problem that the installation of the cover plate and bends on the trough is independent of each other in the traditional method, and the bends cannot help the cover plate to stabilize the installation.

[0025] 2. Compared with the prior art, in the bend, since the outer side of the connecting rod has several connecting holes, both ends of the bend are fixed with a load-bearing plate that can be inserted into the load-bearing hole. The free end of the load-bearing plate is provided with a pin that can be inserted into the connecting hole. The pin and the outer periphery of the load-bearing plate are wrapped with friction pads. The setting of the connecting holes makes the installation of the bend more stable. Under the action of the friction pad and the load-bearing plate, the installation of the bend has a certain strength, avoiding the disconnection of the connection between the bend and the groove.

[0026] 3. Compared with existing technologies, this structure does not use traditional bolt connections, eliminating threaded connections, which makes the installation of this structure simpler, and on the basis of simple installation, the stability of the structure in use can be guaranteed. Attached Figure Description

[0027] To more clearly illustrate the technical solutions in the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0028] Figure 1 A schematic diagram of a trough-type cable tray according to an embodiment of this application is shown. Detailed Implementation

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] The reference numerals in the accompanying drawings include: 1. groove body; 2. cover plate; 3. insertion rod; 4. connecting rod; 5. connecting hole; 6. mounting hole; 7. load-bearing hole; 8. load-bearing plate; 9. pin; 10. bend; 11. detachable plate; 12. matching hole.

[0031] Implementation, for example Figure 1 As shown:

[0032] A trough-type cable tray includes a trough body 1, a cover plate 2, and a bend 10;

[0033] Tank 1: Several mounting holes 6 are evenly opened on the top of the tank 1, and matching holes 12 are also opened on the top of the tank 1. A load-bearing hole 7 communicating with the matching hole 12 is opened on the outside of the tank 1.

[0034] The matching cover plate 2: The cover plate 2 is fixed with several insertion rods 3 at the position corresponding to the mounting hole 6, and a connecting rod 4 is fixed at the position corresponding to the matching hole 12. Several connecting holes 5 are opened on the outer side of the connecting rod 4.

[0035] The matching bend 10: Both ends of the bend 10 are fixedly connected to a load-bearing plate 8 that can be inserted into the load-bearing hole 7, and the free end of the load-bearing plate 8 is provided with a pin 9 that can be inserted into the connection hole 5.

[0036] The outer periphery of the pin 9 and the load-bearing plate 8 is covered with friction pads.

[0037] In terms of overall materials:

[0038] The tank body 1, cover plate 2, and bend 10 are all made of the same material, aluminum alloy. Using the same material helps ensure the approximate service life of the three components, as aluminum alloy is lightweight, high-strength, aesthetically pleasing, has good heat dissipation, and strong corrosion resistance.

[0039] like Figure 1 As shown, the trough 1 is a concave trough 1. The concave trough 1 is the basic shape of the trough-type cable tray, which has the characteristics of low mold opening cost and mature technology. For the trough-type cable tray, the concave trough 1 is the simplest structure and the structure with the most channels is the easiest to obtain.

[0040] About friction pads:

[0041] The friction pad is made of rubber. The rubber friction pad further enhances the friction force, thereby improving the connection stability of the bend 10 and ensuring the connection stability of the bend 10. The pin 9, which is wrapped with the friction pad, is in clearance fit with the connecting hole 5.

[0042] Specifically: Although the connection between the bend 10 and the groove 1 is made by a pin 9, in order to further enhance the connection stability of the bend 10, friction pads are wrapped around the outer periphery of the pin 9 and the bearing plate 8. This results in greater friction when the pin 9 is connected to the connection hole 5 and the bearing plate 8 is connected to the bearing hole 7, thereby making the connection stability of the bend 10 higher.

[0043] The trough 1 is a trough-shaped component bent from a single sheet of steel, such as... Figure 1As shown, both the load-bearing hole 7 and the matching hole 12 are cylindrical holes. The mounting hole 6 and the matching hole 12 have the same depth, and the inner diameter of the matching hole 12 is larger than the inner diameter of the mounting hole 6. Since the matching hole 12 is needed to cooperate with the bend 10, the inner diameter of the matching hole 12 is larger than that of the mounting hole 6. The matching hole 12 is used to install the cover plate 2, so as to achieve stable installation of the cover plate 2.

[0044] The same depth between the mounting hole 6 and the matching hole 12 is to facilitate the installation of the cover plate 2. When the insertion rod 3 is inserted into the mounting hole 6, the connecting rod 4 can be inserted into the matching hole 12 at the same time, thereby exposing the connecting hole 5 towards the load-bearing hole 7, which is beneficial for the subsequent installation of the bend 10.

[0045] The width of cover plate 2 is greater than the width of tank 1. This wider cover plate 2 ensures that the tank 1 is fully covered, making the entire structure appear more aesthetically pleasing.

[0046] The size of the load-bearing hole 7 is larger than that of the matching hole 12 because the load-bearing hole 7 is needed to install the load-bearing plate 8. The load-bearing plate 8 needs to bear the strength of the connection between the bend 10 and the groove 1. Therefore, the size of the load-bearing hole 7 is designed to be larger than that of the matching hole 12.

[0047] When using this utility model, the required structure is determined according to the type of cable to be laid. Then, the trough 1 is taken out, the cover plate 2 is installed, the insertion rod 3 and the connecting rod 4 on the cover plate 2 are installed on the trough 1, and then the connecting hole 5 is exposed toward the bearing hole 7. After the connecting hole 5 is exposed, the bend 10 is installed.

[0048] The load-bearing plate 8 on the bend 10 is installed with the load-bearing hole 7. The friction pad on the load-bearing plate 8 is used to increase the friction between the two during installation. After the load-bearing plate 8 is installed, the pin 9 is naturally installed in the connection hole 5. Since the pin 9, which is wrapped with the friction pad, is in clearance fit with the connection hole 5, the connection stability between the bend 10 and the groove 1 is strengthened.

[0049] After the structure is installed, it has a straight channel 1 and a bend 10. The number of bends 10 and the bending angle are determined according to the terrain. Then the cable enters from one end of the structure and exits from the other end. If the cable does not pass smoothly, the detachable plate 11 needs to be opened and the cable manually adjusted. After the adjustment is completed, the detachable plate 11 is installed again, so that the cable can be laid by the structure.

[0050] This device solves the problem that the traditional installation of the cover plate 2 and the bend 10 on the groove 1 is independent and cannot help each other to stabilize the installation.

[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
