Abstract
The utility model belongs to improvement of a movable guard bar structure, in particular to a gas spring supporting movable guard bar, which comprises a handle and a gas spring which are arranged on a transverse bar. The transverse bar is hinged to the upper ends of hinge supporting bars which are evenly arranged; the lower ends of the hinge supporting bars are all hinged onto a workbench; the middle portion of each hinge supporting bar is in hinge engagement with the upper end of the gas spring; the lower end of the gas spring is in hinge engagement on the workbench; the gas spring is formed by a bar cylinder and a telescopic bar; the telescopic bar extends into the bar cylinder with a blind end and movably matches with the inner circumferential wall of the bar cylinder in sealing manner; and the gas spring enables the hinge supporting bars to be supported vertically through extension of self-elasticity or enables the hinge supporting bars to be placed horizontally through contraction of the self-elasticity. The gas spring supporting movable guard bar is light and convenient in use, stable in lifting, and can avoid being jammed or suddenly lowered to the bottom portion.
Description
Technical field
The utility model belongs to the improvement of movable rail structure, particularly air spring brace type movable rail.
Background technology
Existing Purely mechanical guardrail uses heavy, and rising or falling speed is fast, easily take place stuck or, work high above the ground is used dangerous, easily breaks down.
The utility model content
The purpose of this utility model is to provide a kind of air spring brace type movable rail, uses lightly, and lifting is mild, phenomenon stuck or that reduce to the bottom suddenly can not occur.
The purpose of this utility model is achieved in that a kind of air spring brace type movable rail, comprise the handrail and the air spring that are arranged on the cross bar, the hinged strut upper end of cross bar and uniform setting is hinged, hinged strut lower end all is hinged on the workbench, the middle part of each hinged strut and air spring hinged cooperation of upper end, air spring lower end coordination hinge is on workbench; Air spring is made of bar tube and expansion link, and expansion link stretches into the bar tube that an end is a cecum, seals movingly with its internal perisporium; This air spring is vertically propped up hinged strut by himself elastic elongation or is made hinged strut by horizontal positioned by himself elastic shrinkage.
The utility model adopts air spring (having another name called the tailgate strut), with hinged strut and flexible connection.During use, only stull place handrail in guardrail top is mentioned gently, make hinged strut reach the position vertical with table surface, air spring puts in place, and the back is automatic to tighten, situation is under obsolete situation, according to explanation, force in the guardrail handrail at certain angle, can make guardrail reduce to bottom fixed support top airfoil gently.Be used for the protection in vehicle upper and other work high above the ground districts.The utility model uses light, and lifting is mild, phenomenon stuck or that reduce to the bottom suddenly can not occur.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structure enlarged diagram at A place among Fig. 1.
The specific embodiment
A kind of air spring brace type movable rail, as shown in Figure 1 and Figure 2, comprise the handrail 1 and the air spring that are arranged on the cross bar 3, cross bar 3 is hinged with hinged strut 2 upper ends of uniform setting, hinged strut 2 lower ends all are hinged on the workbench 6, the middle part of each hinged strut 2 and air spring hinged cooperation of upper end, air spring lower end coordination hinge is on workbench 6; Air spring is made of bar tube 5 and the expansion link 4 that an end seals, the other end is opening, and expansion link 4 stretches into bar tube 5 and seals movingly with its internal perisporium; This air spring is vertically propped up hinged strut 2 by himself elastic elongation or is made hinged strut 2 by horizontal positioned by himself elastic shrinkage, and hinged strut 2 lower ends are hinged on the hinged seat 7 that is fixed on the workbench respectively.
