Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a cable tray that is convenient and quick to install and connect. Background Technology

[0002] Cable trays are devices used for laying cables. They are usually composed of trays, ladders, cable troughs and their supports. Their function is to provide a relatively safe and stable environment for cables, avoid the impact of external factors (such as mechanical damage, moisture, corrosion, etc.), and extend the service life of the cables.

[0003] However, traditional cable trays are usually fixed in angle, which cannot flexibly adapt to the cable routing requirements of different installation scenarios. For example, in some industrial plants, due to the placement of large equipment and the intersection of pipes, cables need to bypass obstacles and connect to equipment in different areas at a specific angle. Fixed-angle cable trays simply cannot achieve this operation, which leads to the need to adopt complex and unstable temporary support measures during cable installation. The overall operation is more complicated, which not only increases the difficulty and cost of construction, but also poses safety hazards. Therefore, a cable tray that is convenient and quick to install and connect is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cable tray that is convenient and quick to install and connect, aiming to improve the problem that the fixed-angle cable trays in the prior art are difficult to adapt to cable connections at different angles.

[0007] As a further description of the above technical solution:

[0008] The limiting component includes a limiting screw, and a screw hole is opened at the bottom of the fixing post. The outer wall of the limiting screw passes through the connecting ring and is threaded onto the inner wall of the screw hole.

[0009] As a further description of the above technical solution:

[0010] One end of the reset spring is fixedly connected to the inner wall of the fixed post, and the other end of the reset spring is fixedly connected to the rear end of the reset ball. The outer wall of the reset ball penetrates and is slidably connected to the inner wall of the fixed post. The inner wall of the connecting ring has a ball hole, and the reset ball contacts the inner wall of the ball hole.

[0011] As a further description of the above technical solution:

[0012] The top of the fixed column is fixedly connected to the bottom of the cable tray.

[0013] As a further description of the above technical solution:

[0014] The adapter component includes a connecting spring, one end of which is fixedly connected to the inner top wall of the cable tray, and the other end of which is fixedly connected to a limiting post. A circular hole is formed at the front end of the connecting plate, and the rear end of the limiting post is inserted into the circular hole. Square grooves are formed on the left and right sides of the top of the cable tray, and the outer wall of the connecting plate matches the square grooves.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-2 The present invention provides an embodiment of a cable tray that is easy and quick to install and connect, including a cable tray 1. The inner side of the cable tray 1 is used to place cables. An adjustment mechanism 3 is provided at the bottom of the cable tray 1. The adjustment mechanism 3 facilitates the subsequent installation of new cables. An adapter component 2 is provided on the inner side of the top of the cable tray 1. The adapter component 2 facilitates the support of cables of different heights.

[0032] Reference Figures 1-3The adjusting mechanism 3 includes a fixed column 304, and a connecting ring 301 is rotatably connected to the outer wall of the fixed column 304. The fixed column 304 can rotate around the connecting ring 304, and the rotation of both facilitates the installation of cables at different angles. A fixed plate 302 is fixedly connected to the bottom end of the connecting ring 301, and a connecting plate 303 is hinged to the bottom of the fixed plate 302. When the fixed plate 302 needs to be rotated, the connecting plate 303 on one side needs to be rotated upward first. A reset ball 305 is elastically connected to the inner wall of the fixed column 304 through a reset spring 306. The reset ball 305 is used to pre-position the fixed plate 302 after rotation. A limit member is provided on the inner wall of the connecting ring 301, which can fix the fixed plate 302 after rotation.

[0033] Reference Figures 1-3 The limiting component includes a limiting screw 307. A screw hole is opened at the bottom of the fixing post 304. The outer wall of the limiting screw 307 passes through the connecting ring 301 and is threaded to the inner wall of the screw hole. The threaded connection can limit and fix the fixing plate 302. One end of the return spring 306 is fixedly connected to the inner wall of the fixing post 304, and the other end of the return spring 306 is fixedly connected to the rear end of the return ball 305. The return ball 305 is offset from the screw hole. The outer wall of the return ball 305 passes through and slides on the inner wall of the fixing post 304. On the wall, the elasticity of the return spring 306 enables the return ball 305 to have the purpose of reset and pre-position. The inner wall of the connecting ring 301 has a ball hole, and the return ball 305 contacts the inner wall of the ball hole. When the two are in contact, the fixing plate 302 is in a positioning state. At this time, the fixing plate 302 is rotated manually. The cross-section of the fixing column 304 is inverted T-shaped. The inverted T-shape setting prevents the connecting ring 301 from falling off when it rotates. The top of the fixing column 304 is fixedly connected to the bottom of the cable tray 1. The fixed setting can support the connecting ring 301.

[0034] Reference Figures 1-2 and Figure 4The adapter component 2 includes a connecting spring 202. One end of the connecting spring 202 is fixedly connected to the inner top wall of the cable tray 1, and the other end of the connecting spring 202 is fixedly connected to a limiting post 201. The elasticity of the connecting spring 202 enables the limiting post 201 to have the functions of resetting and pre-positioning. A circular hole 203 is opened at the front end of the connecting plate 303, and the rear end of the limiting post 201 is inserted into the circular hole 203. Multiple sets of circular holes 203 are provided, which allows the distance between one set of cable tray 1 and another set of cable tray 1 to be adjusted, thereby accommodating cables of different heights. Square grooves are opened on the left and right sides of the top of the cable tray 1. The outer wall of the cable tray 1 matches the square channel, and the matching setting facilitates the installation and splicing of one set of cable tray 1 as a whole with another set of cable tray 1. The rear end of the limiting post 201 has an inclined surface, which is set upward. When the connecting plate 303 located above splices with the cable tray 1 below, the bottom of the connecting plate 303 can contact and press the inclined surface of the limiting post 201, thereby facilitating the connection. The connecting plate 303 and the cable tray 1 have threaded holes on both the left and right sides. After the two cable tray 1 are connected as a whole, they can be fixed with bolts. The outer wall of the limiting post 201 is slidably connected to the top inner wall of the cable tray 1. The sliding setting facilitates the connection of multiple sets of cable tray 1.

[0035] Working principle: When it is necessary to adjust the cable installation angle, if the fixing plate 302 needs to be rotated, the connecting plate 303 on one side needs to be rotated upward to eliminate the obstruction in the rotation process. Since the fixing column 304 and the connecting ring 301 can rotate relative to each other, the connecting plate 303 is manually rotated, which in turn drives the fixing plate 302 connected to it to rotate, thereby changing the angle of the cable tray 1 to adapt to the installation requirements of cables at different angles. When the fixing plate 302 is rotated, the reset ball 305 will slide in the ball hole on the inner wall of the connecting ring 301. When the spherical surface of the reset ball 305 contacts the inner wall of the ball hole, the fixing plate 302 is in a pre-positioned state. Then, the limiting screw 307 is turned to rotate the adjusted fixing plate 302. After the angle adjustment is completed, the connecting plate 303 is manually loosened. Due to its own weight, the connecting plate 303 will be vertically downward. Then, the top of the next set of cable trays 1 is inserted into the vertically positioned connecting plate 303. During insertion, the bottom end of the connecting plate 303 contacts and presses the inclined surface of the limiting post 201. Then, it is adjusted through multiple sets of round holes 203 so that the inner side of the lower cable tray 1 contacts the bottom of the cable. At this time, due to the elasticity of the connecting spring 202, the limiting post 201 is reset and inserted into the corresponding round hole 203 to complete the positioning. Then, the bolt is turned to complete the installation operation.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
