[0002] Anti-corrosion cable trays are cable trays coated with anti-corrosion materials. They are used for laying cables and are widely used in construction, power, communications and other fields.

[0003] In the construction of anti-corrosion cable trays, the cable trays are generally fixed together by multiple mounting screws and mounting holes. This method is inconvenient, as installers need to install each screw one by one, which increases the difficulty of installation and reduces the efficiency of installation. Utility Model Content

[0004] The purpose of this invention is to provide a trough-type cable tray with high corrosion resistance, which improves the ease of installation between cable trays, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A trough-type cable tray with high corrosion resistance includes a frame body one and a frame body two. A connecting plate one and a connecting plate two are fixedly connected to opposite sides of the frame body one and the frame body two, respectively. The connecting plate one is located on the inner surface of the connecting plate two. A limiting cylinder is fixedly connected to both the front and back of the connecting plate one. A spring is fixedly connected to the inner cavity of the limiting cylinder. A pressing plate with a groove is fixedly connected to one side of the spring. An insert rod is in contact with the inner surface of the pressing plate. A sliding column is fixedly connected to the outer surface of the insert rod. A sliding groove one is opened in the inner cavity of the limiting cylinder. A ring-shaped sliding groove two is opened on the inner surface of the limiting cylinder. The sliding groove two and the sliding groove one are connected. A cylinder body is fixedly connected to the front and back of the connecting plate two at positions corresponding to the limiting cylinder. A through hole is opened between the cylinder body and the connecting plate two. A sliding groove three is opened on the inner surface of the cylinder body. The outer surface of the sliding column is slidably connected to the inner surfaces of the sliding groove three, the sliding groove one, and the sliding groove two, respectively.

[0006] Preferably, the sliding column is initially slidably connected to the inner surface of the sliding groove three. After sliding to the inner surface of the sliding groove one, the insert rod is rotated counterclockwise to compress the pressing plate, thereby causing the sliding column to engage with the inner surface of the sliding groove two.

[0007] Preferably, the second slide is centrally symmetrical about the axis of the limiting cylinder, and the second slide and the first slide are connected at a 90-degree angle.

[0008] Preferably, the surfaces of both frame one and frame two are coated with a polyurethane coating layer.

[0009] Preferably, branch holes are provided at the front and rear positions of both frame one and frame two.

[0010] Preferably, a limiting post is fixedly connected to the bottom of one end face of the connecting plate one, and a limiting hole adapted to be inserted into the limiting post is opened on one end face of the connecting plate two.

[0011] The beneficial effects of this utility model are:

A connecting plate 3 and a connecting plate 4 are fixedly connected to opposite sides of the frame 1 and frame 2, respectively. A limiting post 14 is fixedly connected to the bottom of one end face of the connecting plate 3. A limiting hole 15, adapted to be inserted into the limiting post 14, is provided on one end face of the connecting plate 4. By setting the limiting post 14 to be inserted into the inner surface of the limiting hole 15, support can be provided between the bottoms of the frame 1 and frame 2. The connecting plate 3 is located on the inner surface of the connecting plate 4. Limiting cylinders 5 are fixedly connected to both the front and back of the connecting plate 3. A spring 6 is fixedly connected to the inner cavity of the limiting cylinder 5. A pressing plate 7 with a groove is fixedly connected to one side of the spring 6.

A cylinder body 12 is fixedly connected to the front and back of the connecting plate 24 at positions corresponding to the limiting cylinder 5. A through hole is opened between the cylinder body 12 and the connecting plate 24. A third sliding groove 13 is opened on the inner surface of the cylinder body 12. The outer surface of the sliding column 9 is connected to the third sliding groove 13, the first sliding groove 10, and the second sliding groove 10 respectively. The inner surface of slide groove 2 11 is slidably connected. The initial position of slide post 9 is slidably connected to the inner surface of slide groove 3 13. After sliding to the inner surface of slide groove 1 10, the insert rod 8 is rotated counterclockwise, causing the insert rod 8 to compress the pressing plate 7, thereby causing slide post 9 to engage with the inner surface of slide groove 2 11. Slide groove 2 11 is centrally symmetrical about the axis of the limiting cylinder 5. Slide groove 2 11 and slide groove 1 10 are connected at a 90-degree angle. By setting slide groove 2 11 to be centrally symmetrical about the axis of the limiting cylinder 5, and slide groove 2 11 and slide groove 1 10 to be connected at a 90-degree angle, slide post 9 slides into slide groove 2 11, and the pressing plate 7 presses against slide post 9. The sliding column 9 is attached to the inner surface of the second slide groove 11. The connecting plate 1 is placed on the inner surface of the connecting plate 2 4. The insert rod 8 is inserted into the corresponding cylinder 12, so that the sliding column 9 slides on the inner surface of the third slide groove 13, and then slides to the inner surface of the first slide groove 10, and presses the pressing plate 7, so that the spring 6 is compressed. After sliding to the end of the first slide groove 10, the insert rod 8 is rotated counterclockwise, so that the sliding column 9 slides on the inner surface of the second slide groove 11. At the same time, the elasticity of the spring 6 makes the sliding column 9 fit tightly against the inner surface of the second slide groove 11, achieving the snap-fit ​​effect. By setting the above structure, the installation convenience between cable trays can be improved.

[0025] Example 2:

[0026] Figure 1-3 This invention illustrates a corrosion-resistant trough-type cable tray according to an embodiment of the present invention, comprising a frame 1 and a frame 2.

Then, the insert rod 8 is inserted into the corresponding cylinder 12, causing the sliding post 9 to slide on the inner surface of the sliding groove 3 13, and then slide to the inner surface of the sliding groove 10. During the sliding, the pressing plate 7 is pressed, causing the spring 6 to be compressed. After sliding to the end of the sliding groove 10, the insert rod 8 is rotated counterclockwise, causing the sliding post 9 to slide on the inner surface of the sliding groove 2 11. At the same time, the elasticity of the spring 6 makes the sliding post 9 fit tightly against the inner surface of the sliding groove 2 11, achieving a snap-fit ​​effect. By setting the above structure, the installation convenience between cable trays can be improved.
