Example 1

Referring to fig. 1 to 5, a glass fiber reinforced plastic cable bridge includes a frame body 2 and a cover plate 1 connected to each other, and further includes a fastener; the fastener comprises a movable part arranged on the cover plate 1 and a fixed part arranged on the frame body 2; the movable part at least comprises a shaft lever 111 hinged with the cover plate 1, and a spring 3 is arranged between the shaft lever 111 and the cover plate 1; the fixing part at least comprises a fixing block 211; the fixing block 211 can limit the shaft 111 so that the spring 3 is in a stretched state. Specifically, fig. 1 shows that the fastening member is in a first state, i.e., in a locked state, at this time, the cover plate 1 and the frame body 2 are in a fixed closed state under the action of the fastening member, and the glass fiber reinforced plastic cable bridge is also in a normal working state; fig. 2 shows the fastener in a second state, i.e. in an unlocked state, in which the cover plate 1 and the frame body 2 are not affected by the fastener, and they are in an overlapping state. When in use:

the installation, at first with apron 1 and support body 2 assembly, exert the effort to axostylus axostyle 111 afterwards and make it rotate to fixed block 211 around its pin joint with apron 1, spring 3 is stretched in-process, along with axostylus axostyle 111 is spacing fixed by fixed block 211, spring 3 is in tensile state all the time, exert decurrent effort to apron 1 through this spring 3 from this, can make apron 1 and support body 2 closely butt, thereby realize the locking of apron 1 and support body 2, change the state that figure 2 shows into the state that figure 1 shows promptly;

and during disassembly, acting force is applied to the shaft rod 111 to separate the shaft rod from the limit fixing of the fixing block 211, at the moment, the spring 3 contracts, and the acting force applied to the cover plate 1 and the frame body 2 by the extension of the spring 3 disappears, so that the locking between the cover plate 1 and the frame body 2 is released, namely the state shown in fig. 1 is changed into the state shown in fig. 2.

The fastener has the advantages of simple structure and convenient operation, simplifies the steps of disassembling and assembling the cable bridge, and is beneficial to improving the working efficiency of workers.

Further, as shown in fig. 1, 2 and 3, the fixing block 211 includes a horizontal section 2111 and a vertical section 2112 which are integrally formed, and the vertical section 2112 is distributed at the lower side of the horizontal section 2111 and is distributed near the spring 3; a limiting plate 2113 is arranged on the vertical section 2112, and the limiting plate 2113 is distributed on one side of the vertical section 2112 away from the spring 3; a clamping groove 2114 for embedding the shaft rod 111 is formed in the fixing block 211, and the clamping groove 2114 simultaneously penetrates through the horizontal section 2111, the vertical section 2112 and the limiting plate 2113 and is distributed close to the spring 3; a clamping block 1112 is sleeved outside the shaft rod 111 in a sliding manner; when the shaft 111 is embedded in the slot 2114, the engaging blocks 1112 are disposed on the upper side of the position-limiting plate 2113 and abut against the vertical section 2112. When using, the rotation axostylus axostyle 111 makes its embedding draw-in groove 2114 in the state that the limiting plate 2113 is between axostylus axostyle 111 and spring 3, then promotes joint piece 1112 and upwards slides, makes it be in limiting plate 2113 upside, no longer exerts force to axostylus axostyle 111 this moment, and axostylus axostyle 111 makes joint piece 1112 support tightly vertical section 2112 under the effect of spring 3, and in this embodiment, the width of joint piece 1112 is greater than the width of draw-in groove 2114. The stopper plate 2113 prevents the catch block 1112 from coming off the vertical section 2112 in the axial direction of the shaft 111.

In this embodiment, the free end of the shaft 111 is configured with a handle 1111. The handle 1111 here facilitates the operation of the shaft 111 by the staff on the one hand; on the other hand, the stopper 1112 can be limited to prevent it from separating from the shaft 111.

In this embodiment, the movable portion further includes a first mounting plate 11, and the first mounting plate 11 is mounted on the side wall of the cover plate 1; the shaft 111 and the spring 3 are both arranged on the first mounting plate 11. The fixing part also comprises a second mounting plate 21, and the second mounting plate 21 is arranged on the side wall of the frame body 2; the fixing block 211 is disposed on the second mounting plate 21. The first mounting plate 11 is fixedly connected with the cover plate 1 through screws; the second mounting plate 21 is connected with the frame body 2 through screws.

As shown in fig. 5, a rack groove 22 is formed in the inner cavity of the rack body 2, and a plurality of partition plates 221 are spaced in the rack groove 22. The wire rack groove 22 is mounted in the inner cavity of the frame body 2 through a support rod 23. The plurality of partition plates 221 can divide the wire rack slot 22 into a plurality of areas, which is beneficial to classified erection of cables and is convenient for later-stage maintenance.

It should be noted that, because the acting force exerted by the spring 3 on the cover plate 1 is directed obliquely downward, the cover plate 1 tends to move in the horizontal direction relative to the frame body 2, and in order to eliminate this effect, it is preferable that the acting force exerted by the spring 3 on the cover plate 1 in the horizontal direction in two adjacent fasteners is opposite in direction during assembly, as shown in fig. 4 in particular.

Example 2

This embodiment is a further improvement of embodiment 1, and repeated contents are not described herein again.

As shown in fig. 6 and 7, the fixing block 211 is disposed on an outer wall of the frame body 2; the fixing block 211 is provided with a slot 2114 for embedding the shaft rod 111, and the slot 2114 is distributed on one side of the fixing block 211 far away from the spring 3. In this embodiment, the slot 2114 limits the shaft rod 111, so that the fixing process of the shaft rod 111 is simplified, and the practicability is high.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
