Description
Technical field
The utility model is related to speed measuring equipment, more particularly to vehicle speed measuring equipment, specially a kind of roller type vehicle speed measuring
Equipment.
Background technology
Roller type speed measuring equipment is a kind of common vehicle speed measuring equipment, and it mainly includes roller, bracket component, expansion link
And velocity sensor, wherein bracket component include support frame and fixed cover, roller supporting is on support frame, and fixed cover is fixed on car
Frame bottom, support frame is connected with fixed cover by expansion link.Although expansion link is flexible along fixed cover axial elasticity, so that with one
Fixed cushioning effect, and cause roller to be close to road surface, but roller is when passing through rugged road surface, expansion link bear it is larger should
Power, is easily bent, and causes expansion link to engage with fixed cover, and influence is normally tested the speed.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of roller type vehicle speed measuring equipment, it can solve prior art
Middle expansion link easily engages with fixed cover, influences the technical problem normally tested the speed.
Its technical scheme is such, and it includes roller, test the speed inductor and rolling wheel support, and the roller passes through roller shaft
The rolling wheel support lower end part is supported in, the inductor that tests the speed connects the roller shaft, it is characterised in that：It also includes electricity
Machine, runing rest and spring leaf；
The runing rest is fixed on the output end of the motor and the first groove provided with opening down setting；
The rolling wheel support is obliquely installed relative to the runing rest, its upper-end part of driving is connected pivotally to by rotating shaft
In first groove；
The spring leaf includes flat upper connecting portion and lower connecting portion, and the upper connecting portion of connection and lower connecting portion
The elastic portion of arc shape, the spring leaf is arranged in first groove and positioned at the top of the rolling wheel support, the bullet
The upper connecting portion of reed is fixedly connected with the roof of first groove, the upper-end part of driving of its lower connecting portion and the rolling wheel support
It is fixedly connected.
Further, the upper-end part of driving of the rolling wheel support is provided with the plane fitted with the lower connecting portion of the spring leaf.
Further, the lower end part of the rolling wheel support is provided with the second groove, and the side wall of second groove is provided with the
Provided with the sliding block and the helical spring against sliding block being slidably matched in three grooves, the 3rd groove, the roller is arranged at
Second groove, its roller shaft run through the inductor that tested the speed after the sliding block described in connection.
Further, the both sides in the 3rd recess width direction are respectively fixed with baffle plate.
Support meanss of the present utility model, roller is supported in the lower end part of rolling wheel support, rolling wheel support by roller shaft
Upper-end part of driving be connected pivotally to by rotating shaft in the first groove of runing rest, when roller pass through rugged road surface
When, the pivoting of the vertically movable drive rolling wheel support of roller, spring leaf can limit the anglec of rotation of supporting plate so that rolling
Wheel is close to bottom surface；Motor drives runing rest rotation, changes the direction of spring leaf and rolling wheel support so that roller is reciprocating
During, the deformation of spring leaf and the rotation direction of rolling wheel support are adapted；Turned because rolling wheel support can adapt to road surface
Dynamic, not only suffered stress is smaller, and is not in stuck phenomenon.
