Quick-detachment locking mechanism
Technical field
This utility model is related to folding bicycle technical field, specifically, relates to the Quick Release on folding bicycle
Retaining mechanism.
Background technology
Now, the enhancing of the raising with people's living standard and environmental consciousness, the public increasingly favors in green, ring
The vehicles protected, cycling activity green, environmental protection and can also body-building, deep liked by teenager and middle-aged and elderly people,
No matter in city road, country field or leisure parks, the troop of hobby cycling can be seen, wherein, fold certainly
Driving because light, can fold, easy to carry, depth is pursued by youthful.
Folding bicycle is provided with folder and telescopic locking mechanism makes folding bicycle fold, reduce, and reaches occupation of land empty
Between little feature, the seat pipe of folding bicycle, standpipe of bicycle have directivity, its when adjusting height, handlebar and saddle
Direction can not change, otherwise can affect the comfortableness ridden, the telescopic locking mechanism on existing folding bicycle can not
Fixing vertical tube or the direction of seat pipe, can only observe by the naked eye adjustment.
Utility model content
The purpose of this utility model is to provide a kind of quick-detachment locking mechanism, treats that locking tube or bar only can relative quick-detachment lockings
Mechanism slips are it is impossible to rotate relative to Quick Release retaining mechanism.
Disclosed in this utility model, quick-detachment locking mechanism be employed technical scheme comprise that:A kind of quick-detachment locking mechanism, including
Beam ring, handle, screw rod and hinge, described beam ring is provided with breach and through hole, and described through hole runs through breach, on described handle one end
It is provided with eccentric hinge hole, in eccentric hinge hole, described hinge is provided with screwed hole to described hinge, described screw rod passes through logical
Hole, is threadeded with the screwed hole on hinge, and the inner surface of described beam ring is provided with connecting portion and protuberance, and described protuberance passes through to connect
Portion is located at the inner surface of beam ring.
Preferably, described protuberance is triangular prism.
Preferably, described protuberance and breach are in the diametrical position of beam ring.
Disclosed in this utility model, the beneficial effect of quick-detachment locking mechanism is:The inner surface of described beam ring is provided with protuberance, uses
In coordinating with pipe to be tightened, unclamp beam ring, adjust when the pipe tightened moves up and down, it is to avoid pipe rotates relative to beam ring.

Specific embodiment
With reference to specific embodiment and Figure of description, this utility model is further elaborated and illustrates:
Refer to Fig. 1, a kind of quick-detachment locking mechanism, including beam ring 10, handle 20, screw rod 30 and hinge 40.Described beam ring
10 are provided with breach 11 and through hole, and described through hole runs through breach 11, and the inner surface of described beam ring 10 is provided with protuberance 12, described protuberance
12 is triangular prism, and described protuberance 12 passes through the inner surface located at beam ring 10 for the connecting portion 13, and described protuberance 12 and breach 11 are located at bundle
In the diametrical position of ring, reduce the impact to beam ring 10 locking function for the protuberance 12.Described handle 20 one end is provided with eccentric hinged
Hole, in eccentric hinge hole, described hinge 40 is provided with screwed hole to described hinge 40, and described screw rod 30 passes through through hole, with hinge
Screwed hole on axle 40 is threaded.
Refer to Fig. 2-4, connecting tube 50 is provided with groove 51, shape tube 60 is provided with the ditch 61 that cross section is triangle, institute
State shape tube 60 in connecting tube 50, described beam ring 10 is sheathed in connecting tube 50, described connecting portion 13 is located at connecting tube 50
Groove 51 in, described protuberance 12 is placed in the ditch 61 of shape tube 60, then shape tube 60, connecting tube 50 with beam ring 10 in radial direction phase
To fixation, prevent beam ring 10 when unclamping pipe 50, shape tube 60, connecting tube 50 are diametrically being rotated with beam ring 10.
Finally it should be noted that above example is only in order to illustrating the technical solution of the utility model, rather than to this reality
With the restriction of novel protected scope, although having made to explain to this utility model with reference to preferred embodiment, this area general
Lead to it will be appreciated by the skilled person that the technical solution of the utility model can be modified or equivalent, without deviating from this
The spirit and scope of utility model technical scheme.
