Technical Field

[0001] The utility model relates to the technical field of cable installation structures, in particular to a trough type cable bridge. Background Art

[0002] The trough type cable tray, also known as the trough type cable tray, is a fully enclosed cable tray. It is most suitable for laying computer cables, communication cables, thermocouple cables and other control cables of highly sensitive systems. It has good effects on shielding interference of control cables and protecting cables in heavy corrosion environments. However, when splicing this type of trough type cable tray, multiple trough type cable trays need to be connected by connecting plates and screws. This connection requires the installation of multiple bolts, so the installation is time-consuming and labor-intensive, reducing the installation efficiency. For this reason, we propose a trough type cable tray. Utility Model Content

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-3 As shown, a trough-type cable tray comprises a cable bottom trough 1 and a packaging end cover 2, wherein the packaging end cover 2 is disposed on the upper port of the cable bottom trough 1, a connection structure 4 is fixedly installed on both sides of one end of the cable bottom trough 1, and a locking structure 3 is fixedly installed on both sides of the other end of the cable bottom trough 1;

[0018] The locking structure 3 includes a mounting cylindrical box 301, a rotating shaft 302, a locking pin 303 and a reset torsion spring 304. The mounting cylindrical box 301 is fixedly mounted on the bottom surface of the inner side of the cable bottom trough 1. The lower end of the rotating shaft 302 is interlaced and movably mounted with the mounting cylindrical box 301. The upper end of the rotating shaft 302 is interlaced and movably mounted with the edge of the upper port of the cable bottom trough 1. The surface of the rotating shaft 302 is fixedly mounted with a locking pin 303. The surface of the rotating shaft 302 is fixedly connected with a reset torsion spring 304. The other end of the reset torsion spring 304 is fixedly connected to the lower surface of the inner side of the mounting cylindrical box 301. The reset torsion spring 304 always applies a force to the rotating shaft 302 so that the end of the reset torsion spring 304 is pressed against the side wall inside the cable bottom trough 1, so that after the ratchet 402 is embedded, the locking pin 303 can be inserted into the gap between the ratchet teeth 402 to lock the connecting plate 401; the connecting structure 4 includes a connecting plate 401 and a ratchet 402, and the surface of the connecting plate 401 is fixedly mounted with a ratchet 402, and a plurality of ratchet teeth 402 are provided; the ratchet 402 is matched with the locking pin 303, and the locking structure 3 is provided with two on each side inside the cable bottom trough 1.

[0019] It should be noted that the utility model is a trough-type cable tray. When performing splicing and installation, the connecting plate 401 on the first cable bottom trough 1 is inserted into the gap between the rotating shaft 302 on the inner side of the second cable bottom trough 1 and the inner wall of the cable bottom trough 1. Then, it is only necessary to continue to push the first cable bottom trough 1 so that the connecting plate 401 continues to be plugged in until the ends of the first cable bottom trough 1 and the second cable bottom trough 1 are in contact to complete the docking. After docking, the locking pin 303 on the second cable bottom trough 1 is screwed with the rotating shaft 302 by the force of the reset torsion spring 304 so that the locking pin 303 is stuck in the gap between the ratchet teeth 402, so that the connecting plate 401 can be fixed in the second cable bottom trough 1, and the two cable bottom troughs 1 are connected. In this way, the connection and installation of multiple trough-type cable trays can be completed. After installation and wiring, the encapsulating end cover 2 can be covered on the cable bottom trough 1.

[0020] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
