Specific embodiment
In conjunction with referring to shown in Fig. 1 to Fig. 3, according to an embodiment of the present application, castor includes foot wheel carrier 1, wheel shaft 2 and idler wheel 3,
Wheel shaft 2 is threaded through on foot wheel carrier 1, and idler wheel 3 is rotatably arranged on wheel shaft 2 relative to foot wheel carrier 1, and the both ends of wheel shaft 2 are worn
The stop configurations by 3 backstop of idler wheel outside axle hole 4 are provided with out outside the axle hole 4 of idler wheel 3, and on the part being pierced by.
Since wheel shaft 2 is worn out outside the axle hole 4 of idler wheel 3, can be pierced by being arranged outside axle hole 4 in wheel shaft 2
The diameter of stop configurations on point does larger, so that wheel shaft 2, stop configurations and idler wheel 3 are integrated substantially, effectively substitutes
The structure of wheel shaft 2 in the prior art and idler wheel 3 necked dimension interference fit, enables wheel shaft 2 to preferably remain in foot
On wheel carrier 1, it is possible to prevente effectively from there is a phenomenon where wheel shafts 2 to fall off, stability and reliability in 3 motion process of idler wheel are improved,
Improve castor reliability.
Wheel shaft 2 is an integral structure in itself, and stop configurations include the detachable structure that at least one end of wheel shaft 2 is arranged in,
Such as retaining ring either circlip etc., and stop configurations are set up directly on wheel shaft 2, so that the stress of idler wheel 3 all falls within wheel shaft 2
On, the globality of stress is improved, integrally-built reliability is improved.
Preferably, stop configurations include the stop lug that 2 one end of wheel shaft is arranged in and the circlip that 2 other end of wheel shaft is arranged in
5.The stop lug can be integrally formed with wheel shaft 2, and circlip 5 is arranged in the other end, be can be convenient the installation for carrying out wheel shaft 2, worked as wheel
After axis 2 is installed, circlip 5 can be stuck in the end of wheel shaft 2, to form axial limiting to wheel shaft 2, effectively prevent occurring
2 obscission of wheel shaft.
In the present embodiment, stop configurations include the circlip 5 that 2 end of wheel shaft is arranged in.In the present embodiment, wheel shaft 2
Both ends pass through circlip 5 and carry out clamping positioning, both facilitate and realize that the assembly and disassembly of wheel shaft 2 are fixed, and can be realized by circlip 5
More good fastening.
The end of wheel shaft 2 is provided with card slot 6, and circlip 5 is embedded in card slot 6.By forming card slot 6, Ke Yifang on wheel shaft 2
Just the processing for carrying out card slot 6, reduces difficulty of processing, while can reduce the influence to 2 structural strength of wheel shaft.
Pin hole also can be set in the both ends of wheel shaft 2, is then realized by way of pin shaft is arranged in pin hole to idler wheel 3
Axial limiting.
In the present embodiment, the inner ring of circlip 5 includes concaveconvex structure, the tensioned opening 7 of side setting of circlip 5.Pass through
Concaveconvex structure is set in the inner ring of circlip 5, the internal stress of circlip 5 can be changed, the installation difficulty of circlip 5 is reduced, mention simultaneously
The impact strength of high circlip 5.
Preferably, the inner ring of circlip 5 is cross bath.
Idler wheel 3 is two, and one of idler wheel 3 is arranged on the wheel shaft 2 of 1 first end of foot wheel carrier, the setting of another idler wheel 3
On the wheel shaft 2 of 1 second end of foot wheel carrier.
The outer end setting fluted 8 of idler wheel 3, stop configurations are located in groove 8.By the equal setting of stop configurations such as circlip 5
In groove 8, it can be avoided circlip 5 and expose outside idler wheel 3, effect protection could be formed with to circlip 5.Preferably, the end of wheel shaft 2
It also is located in groove 8, can be avoided wheel shaft 2 and stretch out outside idler wheel 3, cause when carrying out the displacement of mobile device etc., with other knots
Structure interferes, and scratches other structures or user etc., improves the safety and reliability that castor uses.
The material of circlip 5 is thermally treated carbon steel.
The castor of the application, by by the direct aperture of idler wheel 3, so that being had after wheel shaft 2 directly stretches out idler wheel 3 using circlip 5
Effect is fixed so that wheel shaft 2, idler wheel 3, circlip 5 form an entirety, can so make entire castor formed an entirety by
Power structure, so that castor load-bearing property greatly promotes, the external anti-impact force of castor in enhancing complete machine turnover transportational process, simultaneously
Wheel shaft 2 is effectively fastened using circlip 5, wheel shaft 2 can be made thoroughly to be locked on idler wheel 3, forms entirety, it is possible to prevente effectively from
The case where wheel shaft 2 is deviate from, solves the problems, such as after sale.
Circlip 5 is the utility model structural key component, impact resistance, wear-resisting using the thermally treated higher carbon steel of hardness
Property will be got well, and can effectively play fastening effect.
By this novel idler wheel 3, circlip 5,2 integral structure of wheel shaft, it can utmostly improve the force way of castor
And tightness, the load-bearing property of castor is greatly promoted, and thoroughly solve the problems, such as that castor wheel shaft after sale loosens, to Products
Quality and brand image promotion have larger facilitation.
