Description
Technical field
It the utility model is related to a kind of castor dustproof construction.
Background technology
Castor is widely used because mobile carry an object is convenient for people in equipment for it.Since castor is exposed outside,
And device bottom is usually located at, various environment can be touched and various problems occur, as dust accumulation or debris winding influence castor
It is normal to rotate, reduce the service life.For this reason, part castor has installed dustproof cover additional, but existing dustproof cover is only solid by perforating
It is scheduled in castor shaft, dustproof cover can follow the rotation of castor to slide under this kind of fixed form, make dustproof cover and shaft
Easily there is gap in cracking for junction, causes dust-proof effect and life of product to decline.
Utility model content
To overcome prior art problem, the utility model proposes a kind of castor dustproof construction, stabilized structure, dust-proof effect are good
And it is easy for installation, be designed beautifully it is generous.
The utility model proposes a kind of castor dustproof construction, including the first dustproof cover and the second dustproof cover, described second are anti-
Dirt lid lid is located on the bearing of castor, which is equipped with axis hole, and axis hole periphery is equipped with boss, first dustproof cover
It is covered on the wheel hub of castor, which is equipped with the first mounting hole corresponding with the boss, described for being sleeved on
Clamping fixed on boss.During installation, the second dustproof cover, which is covered, to be sleeved on the second dustproof cover, passes through in bearing both sides, the first dustproof cover
The shaft of castor is fixed through castor carrier with the axis hole.
In the utility model one or more embodiment, the boss include it is some to the second dustproof cover periphery extension
Double wedge, contributes to the further clamping fixed of the first dustproof cover, prevents rotational slip.
In the utility model one or more embodiment, further include and be located between the first dustproof cover and the second dustproof cover
Strengthen lid, the reinforcement, which covers, is equipped with the second mounting hole corresponding with the boss, for being sleeved on clamping fixed on the boss.
In the utility model one or more embodiment, the thickness for strengthening lid is less than the thickness of the first dustproof cover,
Cavity is formed between the reinforcement lid and the first dustproof cover, the effect with bumper and absorbing shock.
In the utility model one or more embodiment, first dustproof cover is equipped with corresponding with the wheel carrier of castor
Fixing groove, first mounting hole are opened in the fixing groove.
In the utility model one or more embodiment, first dustproof cover and reinforcement cover and are equipped with some arcs
Recess.Finger grip is facilitated to be installed, the arc recess of the first dustproof cover is uniformly distributed in addition, and good appearance is generous.
In the utility model one or more embodiment, first dustproof cover, the second dustproof cover and reinforcement lid are Buddhist nun
Dragon-polypropylene blending modified material.
The beneficial effects of the utility model：
1st, the setting of the first dustproof cover of the utility model and the second dustproof cover, to bearing and wheel hub double protection；And first
Dustproof cover is coordinated by the boss of the second dustproof cover to be fixed, and stabilized structure is easy for installation.
2nd, strengthen the setting of lid, the stability of reinforcement structure, and strengthen forming cavity between lid and the first dustproof cover, have slow
The effect of shake is eaten up part of, lifts the impact resistance of product.
3rd, the first dustproof cover, the second dustproof cover and reinforcement lid are nylon-polypropylene blending modified material, wear-resisting, corrosion-resistant,
It is excellent in cushion effect.
Brief description of the drawings
Fig. 1 is the structure decomposition figure that the utility model is installed on castor side.
Fig. 2 is the structure decomposition figure that the utility model is installed on castor opposite side.
Fig. 3 is the side structure schematic diagram of the utility model.
Embodiment
Below in conjunction with attached drawing, application scheme is further described：
Referring to attached drawing 1-3, a kind of castor dustproof construction, including the first dustproof cover 1, the second dustproof cover 2 and reinforcement lid 3, institute
State the second dustproof cover 2 lid to be located on the bearing 41 of castor 4, which is equipped with axis hole 21, and the periphery of axis hole 21 is equipped with convex
Platform 22, the boss 22 can be circular or square, and for the present embodiment using circle, the boss 22 includes four to the second dustproof cover
2 periphery extensions, in the double wedge 23 of " ten " font, by preferably the first dustproof cover of clamping fixed 1 of double wedge 23 and strengthen lid 3.Institute
State the first dustproof cover 1 to be covered on the wheel hub 42 of castor 4, which is equipped with and the boss 22 corresponding first
Mounting hole 11, is additionally provided with fixing groove 12 corresponding with the wheel carrier of castor 4 43, first mounting hole on first dustproof cover 1
