Guard cross rod for guardrail

Abstract

The invention relates to a guard cross rod for a guardrail. The guard cross rod comprises a rod body and a plurality of movable modules, and the movable modules are arranged on the rod body and are in sliding connection with the rod body. A sliding groove is formed in the lower end face of the rod body. A sliding rail matched with the sliding groove is arranged on the upper end faces of the movable modules. A groove is formed in the lower end face of each movable module. Springs are fixedly arranged on the side walls of the two sides inside each groove, the two springs are located on the same straight line, the other ends of the springs on the two sides of the groove are connected with a first fixing block and a second fixing block correspondingly, semicircular grooves are formed in the adjacent faces of the first fixing block and the second fixing block, the bottom of the first fixing block is arranged obliquely in the direction of the adjacent face of the second fixing block, and the second fixing block is identical to the first fixing block. The guardrail is clamped between the first fixing block and the second fixing block, the positions of the movable modules in sliding connection with the rod body can change according to the position of the guardrail, an opening in the upper end of the guardrail is completely sealed after installation, and the risk that a passenger tumbles, and the neck of the passenger is clamped in the guardrail is avoided.

Description

technical field [0001] The invention relates to a device for public facilities, in particular to a protective cross bar used on guardrails. Background technique [0002] Recently, the media has reported several incidents about some guardrails getting stuck in the necks of pedestrians and ultimately resulting in the death of pedestrians. However, similar guardrails in some places have not been removed and reinstalled, so accidents have occurred again and again. The guardrails that have caused these accidents are generally Some structures at the upper end of the guardrail are not sealed, so pedestrians or cyclists may get their necks stuck in the guardrail from the opening of the upper end when they accidentally fall, which will cause suffocation and death in a short time, but these must be removed. Guardrails are more troublesome. First of all, the purchase of new guardrails requires a lot of cost, and the front ones will cause a waste of resources. Contents of the inventio...
