Description
Technical field
The utility model relates to castor technical field, specially a kind of mute castor with PU noise reduction sound-absorbing layer.
Background technique
Castor is a general designation, including movable castor and rigid castors.Movable castor also with regard to the universal wheel described in us, it
Structure allows 360 degree rotation；Rigid castors are also direction-caster, it does not have rotational structure, are not able to rotate.Usually two kinds of castors
Typically collocation.
To modern age with the rise of the industrial revolution, more and more equipment need to move, and castor is also just answered in the whole world
With more and more extensive, all trades and professions almost be unable to do without castor.Arrived it is modern with the continuous development of science and technology, equipment is also increasingly
Multi-functional and high usage, castor is just at indispensable component.But it is inadequate now with many castor dampings and shock absorption,
Noise is generated, being carried to certain weight is to have to push away motionless phenomenon, and appearance does not accomplish exquisiter disadvantage, asks for above-mentioned
Topic, carries out innovative design on the basis of original castor.
Summary of the invention
The purpose of this utility model is to provide a kind of mute castors with PU noise reduction sound-absorbing layer, to solve above-mentioned background skill
Shock-absorbing damping is proposed in art, appearance is not exquisite enough, carries the inadequate problem of the ability of weight.
To achieve the above object, the utility model provides the following technical solutions: a kind of mute foot with PU noise reduction sound-absorbing layer
Wheel, including shell, the shell upper end are fixedly connected with vertical shaft, and the vertical shaft upper end offers card slot, engaging in the card slot
It is connected with circlip, the casing center position is connected with horizontal axis, and the both ends of the horizontal axis are fixedly connected with core wheel, the wheel
Core outer ring integrated type is connected with fixed tooth, and the fixed tooth outer ring is connected together and has wheel piece, and the inner ring of the wheel piece is reserved with
Groove.
Preferably, the shell is made by chromium material.
Preferably, the fixed ring gear shape array distribution is in the outer ring of core wheel.
Preferably, the wheel piece and core wheel are made of PU material.
Preferably, the outer diameter of the core wheel is identical as shell and the wheel internal diameter of piece.
Preferably, the fixed tooth in the core wheel outer ring is connected together with wheel piece inner ring groove.
Preferably, the vertical shaft and horizontal axis are made of nodular cast iron.
Preferably, the wheel piece and core wheel at the horizontal axis both ends are symmetric.
Compared with prior art, the utility model has the beneficial effects that this has the mute castor of PU noise reduction sound-absorbing layer, rolling
The PU material production of the part of wheel, this material have high elasticity, intensity height, shock absorption damping, buffering performance height, carrying degree high
The advantages that, allow the muting function of castor to improve, the smoothly fluency pushed away when carrying weight is good, and junction uses ball milling
The material of cast iron makes castor mechanical with the position with connection according to the intensity also higher than steel this material improves plasticity and toughness
Performance is more preferable, improves the utilization rate of castor, and shell uses chromium material to make, this material has the hard characteristics such as anti-oxidant,
The most suitable material in each position, each position, which has been used, does suitable material the product exquisiteness worked it out is allowed to seem easypro
Clothes, however the performance of damping shock-absorbing is bad has resulted in noise, but the utilization of castor material improves utilization rate, damping shock-absorbing
Performance, carrying degree, according to these characteristics allow castor travel during be mute.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained belongs to the range of the utility model protection.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of mute castor with PU noise reduction sound-absorbing layer,
Including shell 1,1 upper end of shell is fixedly connected with vertical shaft 5, and 5 upper end of vertical shaft offers card slot 6, and being connected together in card slot 6 has circlip
7,1 center of shell is connected with horizontal axis 9, and the both ends of horizontal axis 9 are fixedly connected with core wheel 4, and 4 outer ring integrated type of core wheel connects
It is connected to fixed tooth 2, fixed 2 outer ring of tooth, which is connected together, wheel piece 3, and the inner ring of wheel piece 3 reserves fluted 8；
Further, shell 1 is made by chromium material, improves the hard and anti-oxidant of castor；
Further, fixed 2 annular array of tooth is distributed in the outer ring of core wheel 4, and the effect of pawl power is formed with groove 8, allows wheel
Piece 3 is fixed with core wheel 4 and connect；
Further, it takes turns piece 3 and core wheel 4 to be made of PU material, the characteristic of PU material is castor during traveling
There is mute effect；
Further, the outer diameter of core wheel 4 and shell 1 and the wheel internal diameter of piece 3 are identical, the outer diameter and shell 1 of such core wheel 4 and
The internal diameter of wheel piece 3 can be just engaged to together；
Further, the fixed tooth 2 in 4 outer ring of core wheel and wheel 3 inner ring groove 8 of piece are connected together, be core wheel 4 with fixation tooth 2 and
