Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

It should be noted that, in the description of the present invention, the terms "front", "rear", "left", "right", "upper", "lower", "inner", "outer", etc. indicate the directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for convenience of description of the present invention but do not require the present invention to be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention. As used in the description of the present invention, the terms "front," "back," "left," "right," "up," "down" and "in" refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in fig. 1 and 2, the utility model provides a cable bridge, which comprises a cable bridge body 1 and a cover plate 2; the cover plate 2 is of an arch structure, so that the structural strength of the cover plate 2 can be improved, and the cover plate 2 can have certain elasticity in the transverse direction. Two side faces of the cover plate 2 are provided with a plurality of hooks 21 with uniform intervals, two side walls 11 of the cable bridge frame body 1 are provided with through holes 12 matched with the hooks 21, and the through holes 12 are rectangular or circular. The hook 21 is buckled with the through hole 12 to fix the cover plate 2 on the cable bridge. The buffer arc 23 of the hook 21 and the arc-shaped convex block 22 at the tail end of the hook 21 act together to prevent the hook 21 from falling off. When the device is installed, the hook 21 on one side is placed into the through hole 12, the cover plate 2 is transversely extruded by pressing the hooks 21 on the other side one by one, when the hooks 21 can be placed into the through holes 12, hands are loosened, and the hooks 21 automatically spring into the corresponding through holes 12 under the action of elasticity; when the hook is detached, the hook 21 on one side is pressed obliquely downwards, and the hooks 21 are pushed out of the through holes 12 one by one.

In this embodiment, cable testing bridge body 1 is the ladder-type cable testing bridge, and when having wind, wind forms certain pressure to apron 2 inside getting into the cable testing bridge by the below of ladder-type cable testing bridge, is equipped with the even bleeder vent 24 in interval on the apron 2 for the inside wind pressure of release cable testing bridge alleviates the impact of wind to the cable testing bridge to a certain extent. The axis of the air hole 24 is parallel to the bottom surface of the cable bridge body, so that the cable can be prevented from being directly irradiated by sunlight in the absence of wind, a certain protection effect on the cable can be achieved, and meanwhile, sundries falling from the upper side can be prevented from directly impacting the cable through the air hole 24. In general, due to the change of direction, the wind shows a fluctuating characteristic, the fluctuating characteristic can enable the cover plate 2 to move up and down ceaselessly, the cover plate 2 connected in a sliding groove manner is dropped under the impact of the fluctuation, the cover plate 2 in the embodiment still cannot drop the fluctuation, but the cover plate 2 in the embodiment is connected through the hook 21, and the hook 21 is not easy to drop under the combined action of the buffering arc 23 and the bump 22. Firstly, when the cover plate 2 fluctuates up and down, the hook 21 can collide up and down in the through hole 12 on the side wall 11 of the cable bridge, the existence of the buffer arc 23 can make the cover plate 2 rebound up quickly when moving down to the bottom surface of the through hole 12, so that the hook 21 can always block the upper part of the through hole 12, in addition, the convex block 22 always supports against the outer wall surface of the side wall 11 of the cable bridge, the hook 21 is not easy to generate transverse displacement, the hook 21 can not impact transversely, therefore, the connection between the hook 21 and the cable bridge can not be failed easily, and the cover plate 2 can not fall off easily. Even if a certain hook 21 or even a plurality of hooks 21 are damaged and fall off, the hooks 21 are independent from each other and do not influence each other, and the problem that the cover plate 2 falls off cannot easily occur.

Cable testing bridge changes the connected mode between apron 2 and cable testing bridge body 1 into couple 21 formula and is connected, mutual independence between each couple 21, each mutual noninfluency to set up buffering arc 23 and circular-arc lug 22 on couple 21, prevent that couple 21 from droing, set up bleeder vent 24 on the apron 2 and be used for alleviateing the wind pressure, the utility model discloses effectively prevented apron 2 because of the phenomenon that the wind drops, eliminated the potential safety hazard that apron 2 drove and cause.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
