The different use of universal wheel, universal wheel bearing divide iron core, aluminium core, modeling core, and 1 cun to 8 cun of size differs.Wherein iron core, aluminium core one
As be heavy carrying roller, using being equipped with braking apparatus often.In the prior art, universal wheel usually has damping and brake locking dress
It puts, but wherein there is also some defects, such as 102579204 B of CN to disclose a kind of shock-absorbing caster wheel, including wheel carrier and rolling
Wheel, wheel carrier are door type, and the wheel shaft of idler wheel is mounted on the lower end of wheel carrier.The top surface of wheel carrier is equipped with bar hole, a shock structure
Through the bar hole；The shock structure lower end is equipped with the shock structure shaft vertical with shock structure, and shaft both ends are separately positioned on wheel
On two sides of frame, shock structure shaft is located at the top of idler wheel；The lower end of shock structure is equipped with latch plate, and latch plate plate face is with subtracting
Shake the angle that column keeps setting；Spring is equipped between latch plate and wheel top of support；The wheel shaft and spring of idler wheel are located at respectively to be subtracted
Shake the both sides of column shaft.Though this technical solution also provides the technical method that this technical problem of damping is solved with spring, its
Spring shock absorption is confined to idler wheel rear portion, not comprehensive to carry out damping to castor.
Utility model content
The purpose of this utility model is to overcome above-mentioned limitation, a kind of easy to use so as to provide, security performance height, knot
Structure is novel, the trolley Side-braking caster wheel with shock mitigation system of good damping effect.
The purpose of this utility model is achieved through the following technical solutions：A kind of trolley side brake foot with shock mitigation system
Wheel, including screw rod, foot wheel carrier and idler wheel, foot wheel carrier includes two symmetrically arranged support plates and connects the top plate of two support plate,
Two support plates and top plate are structure as a whole, and screw rod is connected on the top plate on foot wheel carrier, and idler wheel is connected by roller shaft and foot wheel carrier
It connects, screw rod lower end is connected with rotating disc, and rotating disc periphery is located in rotation system, and roller shaft is equipped with brake system.
Preferably, the outer surface of roller shaft is equipped with installing plate, and installing plate is connected by the section of multiple springs and support plate
It connects.
Preferably, roller shaft is equipped with concave part and parallel threaded portion, and the groove at concave part is set with brake system one end
The convex block of some connecting rod front ends is engaged.
Preferably, rotating disc periphery is equipped with multiple ball holes, and ball hole is equipped with ball.
Preferably, rotating disc is double-layer structure.
Preferably, idler wheel outer rim is equipped with protrusion.
In conclusion the trolley Side-braking caster wheel with shock mitigation system of the utility model has the following advantages：It is easy to use,
Security performance is high, and structure novel, good damping effect effectively prevents contact of the roller shaft with support plate so as to cause service life
Shortening, double-deck rotation dish structure reduces the friction that generates when castor rotates, and ball is conveniently replaceable compared to bearing and cost
It is relatively low.

Specific embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further
It is described in detail, which is only used for explaining the utility model, does not form the restriction to scope of protection of the utility model.
A kind of trolley Side-braking caster wheel with shock mitigation system as shown in Figure 1, including screw rod 1, foot wheel carrier 2 and idler wheel 3, idler wheel
It is that can meet the structure of embedded supermarket's elevator crawler belt that 3 outer rims, which are equipped with protrusion, and foot wheel carrier 2 includes two symmetrically arranged 4 Hes of support plate
The top plate 5 of two support plate 4 is connected, two support plates 4 and top plate 5 are structure as a whole, and screw rod 1 is connected to the top plate 5 on foot wheel carrier 2
On, idler wheel 3 is connected by roller shaft 6 with foot wheel carrier 2, and 1 lower end of screw rod is connected with rotating disc 7, rotating disc 7 for flexible connection with
