It is a kind of easy to loading and unloading that the purpose of this utility model is to provide, the Slip-sleeve of bicycle of economic and reliable.

The purpose of this utility model is achieved in that

A kind ofly buckle the Slip-sleeve of bicycle of external stability, comprise that the C type is buckled, sliding sleeve and outer pin, it is characterized in that it is that two ends have arc elastic wires U type hook, 240 ° of radians (or iron wire) and buckle that described C type is buckled by the C type; Described sliding sleeve comprises upper sliding sleeve and low sleeve, and the upper sliding sleeve end has the Baltimore groove that can buckle by the C type and the breach that can buckle two ends U type hook by the C type, and the underfooting end was with interior pin interlock up and down in low sleeve was enclosed within; Described outer foot portion has flange, has the breach that can buckle two ends U type hook by the C type on this flange.

Slip-sleeve of bicycle of the present utility model adopts the C type to buckle the external stability sliding sleeve, and upper and lower sliding sleeve is used, and not only loads and unloads very conveniently, and result of use is also even more ideal.Cost is also than cheap, and the more known shift sleeve structure of result of use is even more ideal.Pin in ensureing is pitched accurate interlock in the pin outside, more reliable and stable.

Below will in conjunction with the accompanying drawings Slip-sleeve of bicycle of the present utility model be described further:

Fig. 1 is the structural representation of known Slip-sleeve of bicycle.

Fig. 2 is the decomposing schematic representation of Slip-sleeve of bicycle of the present utility model.

Fig. 3 is the combination cross-sectional schematic of Slip-sleeve of bicycle of the present utility model.

As shown in Figures 2 and 3, Slip-sleeve of bicycle of the present utility model comprises that a C type buckles 50, and it is the iron wire of line footpath Φ 1.2mm that upper sliding sleeve 60 and low sleeve 70, this C type are buckled, profile be 240 ° circular-arc, at tail end the one U type hook perpendicular to cambered surface is arranged respectively; Upper sliding sleeve 60 ends have two chimbs 602 and 603, form a Baltimore groove 601 in the middle of it, and two breach 604 and 605 at 240 ° of angles are arranged on chimb; Outer pin 40 ends have flange 401; Have on the flange two become 240 ° of angles, with sliding sleeve breach 604 and 605 corresponding breach 402 and 403; In low sleeve 70 is enclosed within on the pin 80 with interior pin interlock about in the of 80, play the effect of sliding sleeve and back seat gasket, sliding sleeve is used up and down, the more known shift sleeve structure of effect is even more ideal.

In sum, Slip-sleeve of bicycle of the present utility model adopts the C type to buckle the external stability sliding sleeve, and is used low sleeve, and more known shift sleeve structure is easier to loading and unloading, and manufacturing cost is also than cheap, and effect might as well.
