Description

Technical Field

[0001] The utility model relates to a bridge cover plate connection structure. Background Art

[0002] With the rapid development of people's living standards, cable trays are increasingly used in power construction; cable trays are a rigid structural system composed of straight sections, bends, components, supports (arm brackets), hangers, etc. of trays or ladders that closely support cables.

[0003] Currently, the mainstream fixing methods for bridge cover plates include "7"-shaped clip fixing. The disadvantage of this fixing method is that the cover plate is easy to fall off during the use of the bridge after installation, resulting in the cables being exposed on the outside and unable to play a protective role. There is also a method of fixing the cover plate with self-tapping screws. The disadvantage of self-tapping screw fixing is that the tip of the self-tapping screw will damage the insulation layer of the cable during the fixing process, and there will be a risk of leakage.

[0006] Preferably, the cross-sectional shapes of the lower bridge frame and the upper cover plate are both U-shaped.

[0007] Preferably: a fireproof mat is laid in the lower bridge frame.

[0008] Preferably, both the first through slot and the second through slot are waist-shaped slots, and the shape of the locking block matches the first through slot.

[0009] Preferably, a plurality of inclined grooves are evenly spaced through the two inner walls of the lower bridge frame, each of the plurality of inclined grooves corresponds to one of the first through grooves, and the size of the inclined grooves is larger than the locking block.

[0010] Preferably: a rubber pad is provided on the surface of each locking block.

[0011] Technical effects of the utility model:

[0012] Insert the screw into the second through slot and the first through slot, rotate the screw, the screw drives the locking block to rotate, the locking block enters the inclined slot, and then screw the nut on the screw to complete the fixing of the lower bridge and the upper cover plate;

[0013] In order to prevent the locking block from damaging the cables in the lower bridge, a rubber pad is provided on the surface of each locking block, which can effectively prevent the locking block from damaging the cables in the lower bridge. At the same time, the threaded self-locking of the screw and nut can effectively prevent the upper cover from falling off the lower bridge. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0021] The utility model will be further described below in conjunction with the accompanying drawings.

[0022] See also Figure 1-5The utility model provides a bridge cover plate connection structure, including a lower bridge frame 1, an upper cover plate 2 movably connected to the upper side of the lower bridge frame 1, a plurality of first through grooves 101 are evenly spaced through the two side edges of the lower bridge frame 1, a plurality of second through grooves 201 are evenly spaced through the two side edges of the upper cover plate 2, each second through groove 201 corresponds to its own first through groove 101, connecting parts are provided in the first through groove 101 and the second through groove 201, and the connecting parts include a screw 3, a nut 4 and a locking block 5, one end of the screw 3 is connected to the surface of the locking block 5, the nut 4 is threadedly connected to the surface of the screw 3, and the screw 3 is located in the first through groove 101 and the second through groove 201.

[0023] The cross-sectional shapes of the lower bridge frame 1 and the upper cover plate 2 are both U-shaped. In order to avoid fire in the bridge frame, a fireproof mat is laid in the lower bridge frame 1.

[0024] A better choice is that both the first through groove 101 and the second through groove 201 are waist-shaped grooves, the shape of the locking block 5 matches the first through groove 101, and the size of the locking block 5 is slightly smaller than the first through groove 101 and the second through groove 201, so as to facilitate the locking block 5 to pass through the first through groove 101 and the second through groove 201.

[0025] In another embodiment, in order to avoid that a plurality of inclined grooves 102 are evenly spaced through the two inner walls of the lower bridge frame 1, each of the plurality of inclined grooves 102 corresponds to a first through groove 101, and the size of the inclined groove 102 is larger than the locking block 5, so that the locking block 5 can enter the inclined groove 102 conveniently, and avoid that the locking block 5 rotates with the nut 4 when the nut 4 is rotated. Of course, in order to prevent the locking block 5 from damaging the cables in the lower bridge frame 1, a rubber pad 6 is provided on the surface of each locking block 5.

[0026] Working principle:

[0027] After laying all the cables in the lower bridge 1, cover the upper cover 2, and then make one of the second through slots 201 correspond to the first through slot 101, because the first through slots 101 are evenly spaced and penetrate the lower bridge 1, and the two sides of the upper cover 2 are evenly spaced and penetrated with multiple second through slots 201, and the spacing of the first through slots 101 is the same as the spacing of the second through slots 201, so when the second through slots 201 correspond to their respective first through slots 101, select the appropriate number of connectors according to the needs;

[0028] Insert the screw 3 into the second through groove 201 and the first through groove 101, rotate the screw 3, the screw 3 drives the locking block 5 to rotate, the locking block 5 enters the inclined groove 102, and then screw the nut 4 on the screw 3 to complete the fixation of the lower bridge frame 1 and the upper cover plate 2. The self-locking of the screw 3 and the nut 4 can effectively prevent the upper cover 2 from falling off.
