Vehicle damage can also make personnel come to harm.
Invention content
The purpose of this utility model is to solve problems of the prior art, provides one kind and vehicle being effectively relieved to restrictor bar
Impact, avoid restrictor bar or the drawback collet device of vehicle damage.
To achieve the goals above, the utility model adopts the following technical solution：A kind of elastic collet dress of restrictor bar
It sets, the drawback collet device includes collet, limited block component and elastic component；The collet and the assembly of barrier gate machine core output shaft are solid
It is fixed；The limited block component includes that fixed part, movable part and upper and lower positioning plate, fixed part are connected with movable part by upper and lower positioning plate
It connects, is provided between the fixed part and movable part and holds the straight slot that passes through of elastic component, the upper and lower side of the movable part and collet
Top and the bottom are fixedly connected, and the limited block component is for two and spaced apart；One end of the elastic component and restrictor bar
Fixed, the other end is successively horizontal through the straight slot of two limited block components；Elastic component is fixed close to restrictor bar end with fixed part
Connection.
Preferably, the fixed part and movable part are respectively the positioning pin that upper and lower ends are fixedly connected in upper and lower positioning plate
And shaft, the limited block component are fixed on by shaft on collet.
Preferably, the elastic component is steel spring plate.
Preferably, further include collet case for covering collet, the collet case is close to the end of restrictor bar ratio
Collet is short close to the end of restrictor bar.
Another purpose of the utility model is to provide a kind of banister, including restrictor bar, Road barricade case, further includes as described above
Drawback collet device.
The utility model compared with prior art, has the following advantages that：Restrictor bar can be with the collision course of vehicle
Certain angle is swung, impact of the vehicles or pedestrians to restrictor bar can be effectively relieved, avoid restrictor bar or vehicle damage.

Specific implementation mode
The noun of locality " up and down " in the present embodiment is described according to shown in attached drawing, is not constituted to this practicality
Novel limitation.
1-5 is further described the utility model below in conjunction with the accompanying drawings：As shown in Figure 1, a kind of elasticity of restrictor bar
Cartridge device, the drawback collet device include collet 1, limited block component 2, steel spring plate 3 and collet case 4；The collet 1
It is fixed with Road barricade case；As Figure 2-3, the limited block component includes two panels positioning plate setting up and down, 21 and of positioning pin
Shaft 22 is provided on positioning plate and accommodates the shaft hole 20 that shaft passes through, and positioning pin is fixed between two panels positioning plate, is positioned
There are certain gaps between pin 21 and shaft 22, form straight slot, for across steel spring plate 3, the upper and lower side and folder of shaft 22
First 1 top and the bottom are fixedly connected, and when steel spring plate is deformed by external force, positioning plate can rotate around the axis.The limited block
Component is for two and spaced apart；As illustrated in figures 4-5, one end of the steel spring plate 3 passes through clamping plate 5 and bridge screw group
Part 6 is fixed with restrictor bar 7, and the clamping plate close to steel spring plate 3 is shorter than the clamping plate of close restrictor bar, and the left end of two clamping plates is flat
Together, right end is respectively close to collet 1, collet case 4, and the other end is successively horizontal through the straight slot of two limited block components；By shortcut
The steel spring plate at lock restrictor bar end is welded and fixed with positioning pin 21, and pad 8 is located at the left and right sides of positioning pin 21, avoids spring steel
Plate is deviate from restrictor bar stress deformation.
In order to which appearance is more beautiful, in the open end of collet setting collet case 4, for covering collet, while by spring steel
In the connecting pin of plate and limited block component is covered in.In order to which restrictor bar is when both direction is collided, can flexibly swing
Certain angle, the collet case is shorter close to the end of restrictor bar than collet close to the end of restrictor bar, i.e. collet and folder
The left end of head-shield shell in the same plane, locational space is not provided for restrictor bar swing.
As shown in figure 5, when restrictor bar is collided, since steel spring plate has certain elasticity, and because limit
The upper bottom plate of block assembly can rotate around the axis, so the right end of steel spring plate can the free skating in limited block component
Dynamic, under the action of steel spring plate, as the collision course of vehicle swings certain angle, vehicle pair has been effectively relieved in restrictor bar
The impact of restrictor bar avoids the damage of restrictor bar or vehicle.As shown in figure 4, after impact force disappears, restrictor bar is in steel spring plate
Under the action of be restored to normal condition.
Above-described embodiment is preferred embodiments of the present invention, is not limitations of the present invention.Two limits
The position setting of position block assembly and the size of straight slot need to be determined according to the thickness and elasticity of steel spring plate.Ordinary skill people
Any deformation or amplification that member is done on the basis of the utility model, it is within the protection scope of the present utility model.
