A protective cross bar for guardrails

Abstract

The invention relates to a protective cross bar used on a guardrail, comprising a bar body and several moving modules arranged on the bar body and slidingly connected with the bar body, a chute is provided on the lower end surface of the bar body, and a sliding groove is provided on the upper end surface of the mobile module. For the slide rail that is suitable for the chute, grooves are provided on the lower end surface of the mobile module, springs are respectively fixed in the side walls on both sides of the groove, the two springs are located on the same straight line, and the other ends of the springs on both sides of the groove Connect the first fixed block and the second fixed block respectively, the surface adjacent to the first fixed block and the second fixed block is provided with a semicircular groove, and the bottom of the first fixed block faces upward toward the surface adjacent to the second fixed block Slanted setting, the second fixed block is the same as the first fixed block. In the present invention, the guardrail is clamped between the first fixed block and the second fixed block, and the mobile module slidably connected with the rod body can change its position according to the position of the guardrail. After installation, the upper opening of the guardrail will be completely sealed, and no Risk of neck entrapment after a fall.

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...
