Description
Technical field
The utility model is related to speed measuring equipment, more particularly to vehicle speed measuring equipment, specially a kind of roller of speed measuring equipment
Support meanss.
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 supporting device of speed measuring equipment, it can solve existing
Expansion link easily engages with fixed cover in technology, influences the technical problem normally tested the speed.
Its technical scheme is such, and it includes rolling wheel support, it is characterised in that：Its also include motor, 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, its upper-end part of driving is connected pivotally in first groove by rotating shaft；
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 coordinated with roller, and described second is recessed
The side wall of groove is provided with the 3rd groove coordinated with roller shaft.
Support meanss of the present utility model, roller is installed on rolling wheel support bottom, when roller passes 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.
Brief description of the drawings
Fig. 1 is main structure diagram of the present utility model.
Fig. 2 is that the utility model assembles the dimensional structure diagram after roller.
Embodiment

Runing rest 2 is fixed on the output end of motor 1 and the first groove 21 provided with opening down setting；
Rolling wheel support 4 is obliquely installed, its upper-end part of driving is connected pivotally in the first groove 21 by rotating shaft 5；
Spring leaf 3 includes flat upper connecting portion 31 and lower connecting portion 32, and the upper connecting portion of connection and lower connecting portion
Arc shape elastic portion 33, spring leaf 3 is arranged in the first groove 21 and positioned at the top of rolling wheel support 4, spring leaf it is upper
Connecting portion 31 is fixedly connected with the roof of the first groove 21, its lower connecting portion 32 is fixedly connected with the upper-end part of driving of rolling wheel support 4,
The upper-end part of driving of rolling wheel support is provided with the plane fitted with the lower connecting portion of spring leaf.
The lower end part of rolling wheel support 4 is provided with the second groove 41 coordinated with roller, the side wall of second groove 41
Provided with the 3rd groove 42 coordinated with roller shaft.
In Fig. 2,6 be roller, is installed in the second groove 41, and 7 be velocity sensor, is attached across the rolling of the 3rd groove 42
Wheel shaft.
