Description

Technical Field

[0001] This invention belongs to the field of cable tray technology, specifically relating to a trough-type cable tray device and its installation method. Background Technology

[0002] Cable trays are suitable for laying computer cables, communication cables, thermocouple cables, and other control cables for highly sensitive systems. They offer good shielding against interference and protection for cables in highly corrosive environments. Due to the long length of the cables, multiple cable trays need to be spliced ​​before installation. Currently, splicing two cable trays often involves using multiple screws at the joint, making installation and disassembly cumbersome. Furthermore, during operation, cables generate heat, but the lack of cable fixing structures within the trays leads to disorganized cable distribution and poor heat dissipation, posing safety hazards. This paper proposes a cable tray design that enables rapid installation, disassembly, and fast cable fixing. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a trough-type cable tray device and its installation method.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A trough-type cable tray device includes a first cable tray and a second cable tray, with a connecting structure between the first cable tray and the second cable tray. The connecting structure includes two first clamping plates that are slidably disposed in the first cable tray. The first cable tray is rotatably provided with a bidirectional screw, and the bidirectional screw is threadedly connected to the first clamping plates. One end of the bidirectional screw is fixedly connected to a knob. An installation strip is fixedly disposed in the second cable tray, and two second clamping plates are installed on the installation strip.

[0006] Both the first and second cable trays have partitions fixedly connected inside. Both the first and second cable trays have fixing structures inside. The fixing structures include multiple limiting seats fixedly connected inside the first and second cable trays. Cables are placed on the limiting seats. Connectors are installed on the inner walls of both sides of the first and second cable trays. Rubber sleeves are provided above the connectors. Rotating parts are provided on the connectors. The rotating parts include curved pressure plates hinged to the connectors. Rubber clips are connected to the top of the curved pressure plates. Multiple L-shaped clips are fixedly provided on the curved pressure plates.

[0007] An installation method for a trough-type cable tray device includes the following steps:

[0008] S1. Insert the stabilizing plate on the second cable tray into the stabilizing sleeve on the first cable tray to complete the connection between the first and second cable trays.

[0009] S2. Rotate the knob clockwise to control the movement of the first clamping plate through the bidirectional screw and fix the second clamping plate to complete the fixing of the first cable tray and the second cable tray;

[0010] S3. Place the cable into the limiting seat and fix the cable by rotating the part;

[0011] S4. Close the cover.

[0012] The beneficial effects of this invention are:

[0013] 1. This invention controls the forward and reverse rotation of the bidirectional screw to quickly fix and separate the first and second clamping plates, enabling rapid installation and separation of the two cable trays. At the same time, the cooperation between the stabilizing sleeve and the stabilizing plate effectively increases the stability of the connection between the two cable trays.

[0014] 2. This invention uses a cable to compress a rotating component, causing the component to rotate. The L-shaped clamping plate on the rotating component is controlled to quickly clamp onto the cable surface, fixing the cable to the limiting seat. This achieves rapid cable fixing, resulting in an orderly cable distribution and convenient heat dissipation.

[0015] 3. The present invention provides a movable locking block on the cover plate. After the cover plate is closed, the movable locking block is fitted onto the upper surface of the cable to prevent the cable from detaching from the limiting seat. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0029] like Figures 1 to 8As shown, a trough-type cable tray device includes a first cable tray 1 and a second cable tray 7. A connection structure is provided between the first cable tray 1 and the second cable tray 7. The connection structure includes two first clamping plates 16 symmetrically distributed inside the first cable tray 1, and the first clamping plates 16 are slidably connected to the first cable tray 1. Multiple grooves are provided on the first clamping plates 16. A bidirectional screw 15 is threadedly connected to the two first clamping plates 16. A knob 8 is fixedly connected to one end of the bidirectional screw 15. An installation strip 18 is fixedly connected inside the second cable tray 7. Two second clamping plates 17 are symmetrically installed on the installation strip 18. Multiple protrusions are provided on the second clamping plates 17. By rotating the knob 8 clockwise, the bidirectional screw 15 is controlled to rotate clockwise, thereby controlling the two first clamping plates 16 to move away from each other, so that the protrusions are engaged in the grooves and the second clamping plates 17 are quickly fixed. A stabilizing sleeve 10 is fixedly installed at the bottom end of the first cable tray 1, and a stabilizing plate 9 is fixedly installed at the bottom end of the second cable tray 7. The stabilizing plate 9 is inserted into the stabilizing sleeve 10 to increase the connection stability between the first cable tray 1 and the second cable tray 7.

[0030] Both the first cable tray 1 and the second cable tray 7 are fixedly connected to a partition 12. Both the first cable tray 1 and the second cable tray 7 have a fixing structure, which includes multiple limiting seats 11 fixedly connected inside the first cable tray 1 and the second cable tray 7. The limiting seats 11 are symmetrically distributed on both sides of the partition 12. Cables 2 are placed on the limiting seats 11. A slot 14 is formed in the middle of the limiting seats 11. Connectors 13 are symmetrically installed on the inner walls of both sides of the first cable tray 1 and the second cable tray 7. Rubber sleeves 4 are symmetrically installed on the inner walls of both sides of the first cable tray 1 and the second cable tray 7, and the rubber sleeves 4 are located above the connectors 13. A rotating part 3 is provided on the connector 13. The rotating part 3 includes a hinged component on the connector 13. The curved pressure plate 302 on the 3 has a rubber clamp head 301 connected to its top end, and two L-shaped clamping plates 303 are symmetrically connected to both sides of the curved pressure plate 302. When the cable 2 is placed in the limiting seat 11, the cable 2 squeezes the bottom end of the curved pressure plate 302, causing the curved pressure plate 302 to rotate around the hinge point on the connector 13. The rubber clamp head 301 on the curved pressure plate 302 disengages from the rubber clamp sleeve 4, and the bottom end of the curved pressure plate 302 slides into the slot 14. At the same time, the curved pressure plate 302 drives the two L-shaped clamping plates 303 to move closer to the cable 2. When the cable 2 is completely placed on the limiting seat 11, the L-shaped clamping plates 303 automatically clamp onto the surface of the cable 2, thereby fixing the cable 2.

[0031] Cover plates 5 are installed on both the first cable tray 1 and the second cable tray 7. The cover plate 5 includes a housing 501. A limiting strip 502 is fixedly connected to the housing 501. When the housing 501 is installed on the first cable tray 1 and the second cable tray 7, the top of the partition plate 12 is smoothly fitted into the inside of the limiting strip 502, increasing the stability of the cover plate 5 installation. An installation sleeve 503 is fixedly installed on the lower surface of the housing 501. Multiple springs 505 are fixedly connected inside the installation sleeve 503. A movable locking block 504 is fixedly connected to the bottom end of the springs 505. After the housing 501 is installed on the first cable tray 1 and the second cable tray 7, the movable locking block 504 limits the cable 2 to prevent the bottom end of the curved pressure plate 302 from rotating upward when the first cable tray 1 and the second cable tray 7 shake, causing the cable 2 to disengage from the limiting seat 11. Heat dissipation vents 6 are opened on both sides of the first cable tray 1 and the second cable tray 7 for heat dissipation of the cable 2.

[0032] The installation principle of a trough-type cable tray device is as follows: First, the second cable tray 7 is brought close to the first cable tray 1, so that the stabilizing plate 9 is inserted into the stabilizing sleeve 10. At this time, the second clamping plate 17 is inserted into the interior of the first cable tray 1 along both sides. Then, the knob 8 is rotated clockwise, thereby controlling the bidirectional screw 15 to rotate clockwise, so that the two first clamping plates 16 move away from each other, and the protrusion on the second clamping plate 17 is inserted into the groove on the first clamping plate 16, quickly fixing the second clamping plate 17 between the side wall of the first cable tray 1 and the first clamping plate 16. When the knob 8 is rotated counterclockwise, the bidirectional screw 15 is controlled to control the two first clamping plates 16 to move closer to each other, so that the protrusion on the second clamping plate 17 is disengaged from the groove on the first clamping plate 16, quickly releasing the fixed state of the second clamping plate 17. At this time, the second cable tray 7 is pulled to one side, so that the stabilizing plate 9 is disengaged from the stabilizing sleeve 10, and the second cable tray 7 can be quickly separated from the first cable tray 1.

[0033] Next, the cable 2 is installed onto the limiting seat 11. At this time, the cable 2 presses against the bottom end of the curved pressure plate 302, and the rubber clamp 301 on the curved pressure plate 302 disengages from the rubber clamp 4, causing the curved pressure plate 302 to rotate around the hinge point on the connector 13. The bottom end of the curved pressure plate 302 slides into the slot 14. At the same time, the curved pressure plate 302 drives the two L-shaped clamps 303 to move closer to the cable 2. When the cable 2 is completely placed on the limiting seat 11, the L-shaped clamps 303 are clamped on the surface of the cable 2, so that the cable 2 is fixed on the limiting seat 11. Finally, the cover 501 is installed on the first cable tray 1 and the second cable tray 7. At this time, the movable clamp 504 is clamped on the upper surface of the cable 2 to prevent the cable 2 from disengaging from the limiting seat 11.
