As shown in fig. 1 and 2, a locking device for a cable tray according to a first embodiment of the present application includes a back plate 11, a movable plate 12, and a buckle 13.

The back plate 11 and the movable plate 12 are both half-i-shaped, and each of the back plate and the movable plate includes a main plate and a connecting plate bent along two sides of the main plate in the same direction.

The main board of the back plate 11 has a fixing hook 14 at its outer side, and the fixing hook 14 is used for connecting with a fixing hole 21 of a cable bridge. In some embodiments, the fixing hook 14 includes a folding portion 141, one end of the folding portion 141 is fixedly connected to the back plate 11, and the other end is bent toward the first end of the back plate 11 to form a vertical portion 142, and the vertical portion 142 and the back plate 11 form a clamping position. The fixing hook 14 and the back plate 11 are of an integral structure, and during production, a counter bore forming die is opened, and the back plate 11 is formed into the fixing hook 14 after being subjected to die stamping forming.

The first end of the back plate 11 is hinged with the first end of the movable plate 12. Specifically, the movable plate 12 is located inside the back plate 11, and the connecting plate of the movable plate 12 is connected to the connecting plate of the back plate 11 by a rotating shaft 15, so that the movable plate 12 can rotate about the rotating shaft 15.

One end of the buckle 13 is hinged with the movable plate 12, and the buckle 13 is used for being connected with a fixing lug 31 of the cable bridge. In some embodiments, the hasp 13 is a rectangular piece bent from a wire whose cross section is circular.

The second end of the movable plate 12 is provided with a first connecting piece, and the second end of the back plate 11 is provided with a second connecting piece which can be detachably connected with the first connecting piece. In some embodiments, the first connecting member is a protruding point 121 located on the outer side of the connecting plate of the movable plate 12, and the second connecting member is a recessed point 111 located on the inner side of the connecting plate of the back plate 11. When the movable plate 12 rotates to a certain angle around the rotating shaft 15, the convex points 121 are clamped in the concave points 111, so as to fix the position.

The application of the snap lock for a cable bridge provided by the present application refers to the description of the cable bridge shown in fig. 5 below, and is not repeated herein.

FIG. 4 is a knot schematic view of a cable tray latch provided in a second embodiment of the present application from a perspective.

In practical applications, the lock catch 1 can be provided in various sizes and specifications, and for a small-sized lock catch 1, only one fixing hook 14 needs to be provided on the back plate 11. If the size of the buckle 1 is large, the number of the fixing hooks 14 on the back plate 11 can be increased, and a plurality of the fixing hooks 14 can be arranged in a matrix.

As shown in fig. 5, the application provides a cable tray comprising a trough body 2, a cover plate 3 and a latch 1 as shown in fig. 1-3. The cover plate 3 is fixed at the opening of the tank body 2, the cover plate 3 is provided with a fixing lug 31, and one side of the tank body 2 is provided with a fixing hole 21; the fixing hook 14 of the buckle lock 1 is connected with the fixing hole 21 of the groove body 2, and the buckle 13 is connected with the fixing lug 31.

The application provides the cable testing bridge that the embodiment provided, its method of operation is as follows:

the cover plate 3 is buckled at the opening of the tank body 2;

installing the fixing hook 14 on the back plate 11 of the padlock 1 on the fixing hole 21, specifically, inserting the fixing hook 14 into the fixing hole 21, wherein the fixing hole 21 is a square hole, then pulling the back plate 11 upwards, wherein the vertical part 142 is positioned on the inner side of the tank body 2, the back plate 11 is positioned on the outer side of the tank body 2, and the vertical part 142 and the back plate 11 clamp the tank body 2 to realize the primary fixation of the padlock 1;

the hasp 13 of the padlock 1 is hung on the fixing lug 31;

the movable plate 12 is turned over to rotate around the rotating shaft 15, and during the rotation, the buckles 13 tighten the fixing lugs 31, and finally the convex points 121 of the movable plate 12 are clamped in the concave points 111 of the back plate 11, so as to realize the fixing.

When the goods are delivered, the novel buckle lock 1 and the cable bridge are sent to a construction site together, the novel buckle lock and the cable bridge are in a separated state, when the cover plate 3 is covered after the cable is laid, the operation is carried out according to the operation method, and the cover plate 3 and the groove body 2 are locked efficiently and conveniently.

When the cable bridge is produced, the fixing holes 21 with the corresponding sizes of the fixing fasteners 1 are punched on the bridge trough body 2, the traditional fasteners do not need to be welded or fixed on the trough body 2 by screws in the traditional mode, and the trouble that the bridge trough body 2 is repeatedly carried in a factory and the fasteners 1 are assembled in a time-consuming and labor-consuming manner is avoided.

Although the present application is disclosed above, the present application is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the scope or spirit of the present disclosure, and it is intended that the scope of the present disclosure be defined by the appended claims.
