Description
Technical field
The utility model relates to mechanical rubber technical field more particularly to a kind of castors with shock-absorbing function.
Background technique
Rubber (Rubber) refers to the high elastic polymer material with reversible deformation, high resilience at room temperature, very
Larger deformation can be generated under small external force, removes resilient after external force, and this good characteristic of rubber makes rubber quilt
It is widely used in Tire production industry, but the damping property of tire made of rubber is not also very well, to generally require and add in inside
The interior tire of inflation, in small-sized castor manufacturing process, since part castor is excessively small and exquisite, it has not been convenient to add inflation in inside
Interior tire, so part castor is all with made of solid rubber, it is not fine for leading to the damping effect of castor.
Utility model content
Purpose of the utility model is to solve the damping effect of castor made of solid rubber in the prior art is bad
The problem of, and a kind of castor with shock-absorbing function proposed.
To achieve the goals above, the utility model uses following technical solution：
A kind of castor with shock-absorbing function, including support plate, there are two the lower end of the support plate is symmetrically fixedly connected
Support rod, the lower end between two support rods are equipped with connecting rod, and one end of the connecting rod is through a side support bar and solid
Surely it is connected with fixture nut, the other end of the connecting rod runs through the support rod of the other side and is fixedly connected with threaded rod, described
It is arranged with bearing in connecting rod, is symmetrically fixedly connected on the lateral wall of the bearing there are two ring-like plate, two rings
It is equipped with rubber wheel between shape plate, is fixedly connected with annular backup pad on the inner sidewall of the rubber wheel, the annular backup pad
Bottom end is fixedly connected with the lateral wall of bearing to multiple brute springs, the lower end of each brute spring is symmetrically welded with.
Preferably, two annular slab one end close to each other offer annular groove, and the two of the annular backup pad
End all extends in corresponding annular groove.
Preferably, the air ring that cross section is T-type is fixedly connected on the lateral wall of the rubber wheel.
Preferably, multiple through-holes are offered on the rubber wheel.
Preferably, screw thread is socketed with nut on the threaded rod.
Preferably, anti-skid chequer is offered on the lateral wall of the air ring.
In the utility model, support plate is fixed with external mobile device, and when mobile device is pushed, castor is moved
Dynamic, during castor is mobile, the anti-skid chequer on air ring plays stable effect, prevents the skidding of castor, and air ring expands
The contact area for expanding rubber wheel and ground greatly, more stable when keeping castor mobile, rubber wheel itself also plays the role of damping, opens
If through-hole so that rubber wheel is occurred more deformation, deformation occurs absorbs energy for rubber wheel stress, then brute spring by
Contracting is forced, to play the role of damping, to make castor that more vibration forces can be absorbed, to make the effect of damping more
It is good.The utility model is structurally reasonable, and mobile stabilization will not skid, and reaches the damping effect of castor by the shock-damping structure of multilayer
One good effect.

The orientation or positional relationship of the instructions such as "top", "bottom", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific
Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
Referring to Fig.1-2, a kind of castor with shock-absorbing function, including support plate 1, the moving trolley of support plate 1 and god
It is fixedly connected, the lower end of support plate 1 is symmetrically fixedly connected there are two support rod 2, and the lower end between two support rods 2 is equipped with connection
One end of bar 3, connecting rod 3 through a side support bar 2 and is fixedly connected with fixture nut 4, and the other end of connecting rod 3 is through another
The support rod 2 of side is simultaneously fixedly connected with threaded rod 5, and connecting rod 3 and threaded rod 5 are integrally formed, and screw thread is socketed with spiral shell on threaded rod 5
Cap 6, rotary nut 6 make nut 6 compress support rod 2, and the support rod 2 of the compression of fixture nut 4 other side is made by connecting rod 3, from
And stablize two support rods 2, it is arranged with bearing 7 in connecting rod 3, is symmetrically fixedly connected with that there are two rings on the lateral wall of bearing 7
Template 8, rubber wheel 9 is equipped between two annular slabs 8, and rubber wheel 9 comes with certain damping effect, offers on rubber wheel 9
Multiple through-holes 11, more deformation can occur for the rubber wheel 9 for being provided with multiple through-holes 11, so that more energy are absorbed, thus
Better damping effect is played, the air ring 10 that cross section is T-type, air ring are fixedly connected on the lateral wall of rubber wheel 9
Anti-skid chequer is offered on 10 lateral wall, anti-skid chequer prevents the skidding of rubber wheel 9, and cross section is that the air ring 10 of T-type expands
