The utility model has the advantages of beautiful appearance, high durability, and increased service life.
Description
The utility model relates to a kind of crossing restriction vehicle, freely through alley stopping devices of pedestrian such as toll station, enterprises and institutions, residential quarters of being used for.
At present, all be flat or square as the turning joint of the retractable door of alley stopping device, in use, when turning joint was rotated relative to articulated shaft, its sharp edges was equivalent to articulated shaft is done the break-in of cutting shape, thus the whole life-span of influence.
The purpose of this utility model is to provide a kind of turning joint to have the retractable door of copper sheathing.
The utility model is achieved by the following technical solution: copper sheathing is embedded in the hole of turning joint.
The utility model is aesthetic in appearance, and is durable in use, and improves greatly its application life.
Below in conjunction with accompanying drawing the utility model is further specified:
Accompanying drawing 1 is the utility model outside drawing.
Accompanying drawing 2 is the utility model partial enlarged drawing.
Accompanying drawing 3 is spring leaf 2 front views.
See accompanying drawing 1,2,3, the utility model comprises turning joint 1, spring leaf 2, buckle closure 3, articulated shaft 4, copper sheathing 5, anti-collision switch 6, and copper sheathing 5 is embedded in the hole of turning joint 1.Spring leaf 2 is embedded in buckle closure 3, and the centre of spring leaf 2 is the peripheral hole that has the dentation flange, and the two ends of articulated shaft 4 are fastened on respectively in the hole of spring leaf 2, and anticollision device 6 is loaded on the end that turning joint 1 is advanced.
When using the utility model owing in the hole of turning joint 1, be inlaid with copper sheathing 5, before having eliminated because the cutting shape break-in that flat or square turning joint 1 are done circular articulated shaft 4 in rotation process, thereby improved greatly its application life.
When the two ends of the spring lid buckle closure of forming by spring leaf 2 and buckle closure 3 at articulated shaft 4, articulated shaft 4 makes the peripheral dentation flange of spring leaf 2 interstitial holes by jack-up, and block articulated shaft 4, like this, just can guarantee turning joint 1 aprowl,, thereby prolong application life of the present utility model owing to the reason of pushing makes articulated shaft 4 can not come off out, and, also make the utility model increase aesthetic feeling because buckle closure 3 is buckled in the termination of articulated shaft 4.
If turning joint 1 is in motion process, as when the situation of operate miss or engine failure occurring, anti-collision switch 6 is run into obstruction, can cut off the electricity supply automatically, and turning joint 1 stops action, reaches the purpose that protection people, thing avoid damaging.
