Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Terms used herein, including technical and scientific terms, have the same meaning as terms commonly understood by one of ordinary skill in the art, unless otherwise defined. It will be understood that terms defined in commonly used dictionaries have meanings that are consistent with their meanings in the prior art.

Referring to fig. 1 to 5, a guard rail for civil engineering bridge construction includes a support 1 fixedly connected to the ground; the support 1 is provided with a first hinge seat 2; the first hinge base 2 is internally connected with a connecting rod 3; the other end of the connecting rod 3 is connected in the second hinge seat 4; the second hinged seat 4 is fixedly arranged on the guardrail rod 5; a locking assembly is arranged between the connecting rod and the guardrail rod; a protective net supporting rod 6 is arranged outside the support 1; the protective net supporting rod 6 is linked with the connecting rod 3.

Specifically, the connecting rod is connected between support and guardrail bar through first articulated seat and the articulated seat of second, through promoting guardrail bar, can adjust the contained angle between connecting rod and the support to reach the purpose of adjustment guardrail bar state. Meanwhile, when the angle of the connecting rod changes, the connecting rod and the protective net supporting rod 6 are in linkage relation, the protective net supporting rod is turned outwards from the support 1, and a supporting point is provided for installation of the protective net.

Furthermore, the connecting rods 3 comprise a plurality of connecting rods; each connecting rod 3 is parallel to each other; the locking assembly comprises an angle seat 7, a locking seat 8 and a pressing handle 9.

Furthermore, the corner seat 7 is arranged at the upper end of the connecting rod 3 positioned at the outermost side; the corner seat 7 is provided with a vertical part and a horizontal part; the locking seat 8 is fixedly connected to the bottom of the guardrail bar 5.

Specifically, in the present embodiment, the corner seat 7 is fixed to the end of the outer link, and the upper end of the corner seat is hinged to the locking seat 8.

Furthermore, the surface of the horizontal part is provided with a jack; the horizontal part and the vertical part are arranged at a right angle; a bolt 8.1 matched with the jack is arranged in the locking seat 8; the upper end of the angle seat is hinged with the locking seat.

Specifically, after guardrail bar expandes completely, loosen and press handle 9, the elastic component can push down the bolt for the bolt is from 8 internal downstream of locking seats, and enter into the jack on the corner seat 7, make the angle that is called and between the locking seat unable change again, because locking seat 8 and guardrail bar fixed connection, so guardrail bar has also realized the fixed of position.

When the guardrail needs to be folded, the pressing handle 9 is pressed.

Furthermore, the top end of the bolt 8.1 is connected with the pressing handle 9; the locking seat is provided with an assembly groove body relative to the pressing handle; the pressing handle is connected in the assembling groove body through an elastic piece.

Further, a cavity for placing a protective net supporting rod 6 is formed at the bottom of the support 1; and a contact rod 10 arranged in the extending direction of the connecting rod 3.

Furthermore, the protective net supporting rod 6 is arranged in the cavity through a torsion spring; the contact rod is contacted with the inner end of the protective net support rod.

Specifically, in this embodiment, in the process of the connecting rod 3 turning upwards, the contact rod 10 of the extending portion thereof presses down the inner end of the supporting rod of the protection net (connected to the inside of the cavity through the torsion spring), and the other end of the supporting rod of the protection net turns outwards towards the inside of the cavity, if the connecting rod is folded, the contact rod is separated from the inner end of the supporting rod of the protection net, and the supporting rod of the protection net returns to the inside of the cavity again due to the existence of the torsion spring.

For making contact bar 10 bottom can contact with protection network bracing piece inner, need set up a circular arc arch at contact bar 10 tip, when the connecting rod is in fold condition, the circular arc arch can not contact with the protection network bracing piece, when the connecting rod was in upturning in-process, because the contact bar can be along with its angular variation and downwardly rotating, so the circular arc arch on the contact bar can ejecting crashproof net bracing piece.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
