Abstract
The utility model discloses a take self -locking function's truckle, including total support and gyro wheel, total support includes brake block support, locking part spare support and shaft, and the gyro wheel is installed in the shaft both ends, there is the brake block through rivet hole and fix with rivet on the brake block support, be equipped with locking part spare through location pinhole and locating pin on locking part spare support, the gyro wheel inboard is equipped with the annular groove, and the annular groove has incurvated face and the outer curved surface through handling roughly, be equipped with the inflation post on locking part spare, the brake block comprises two flat spring pieces, and the brake block is pressed to outer curved surface and incurvated face by the extrusion expansion of inflation post. The utility model discloses compact structure, convenient operation, the practicality is strong, and suitcase cooperation that can be direct with different is used, has avoided suitcase atress on car, train to slide at will, and the improvement trip is convenient greatly.
Description
Technical field
This utility model relates to small stores technical field, the castor of a kind of band auto-lock function.
Background technology
Luggage case is applied widely in trip, with the life of people is closely bound up.Accommodating article, while liberation both hands, it has been found that some embarrassments that luggage case exists.Such as when riding public transportation means (public transport, subway etc.), most of luggage cases can not keep as you were according to the wish of people, needs with hand steered or fallen by luggage case or side is put, and luggage case stress arbitrarily moves the safety being also unfavorable for driving.
Summary of the invention
For above-mentioned deficiency of the prior art, the purpose of this utility model is to provide the castor of a kind of band auto-lock function, this Castor structure is compact, easy to operate, practical, can directly from different luggage cases with the use of, it is to avoid luggage case stress on automobile, train is arbitrarily slided, and being greatly improved trip convenient.
The purpose of this utility model is achieved through the following technical solutions:
A kind of castor of band auto-lock function, it is characterised in that: this castor includes that total support and roller, described total support include brake block support, locking component support and wheel shaft, and roller is installed on wheel shaft two ends；Brake block support is fixed with brake block by rivet hole and rivet；Locking component support is provided with locking component by dowel hole and alignment pin；Being provided with annular groove inside described roller, annular groove has negative camber and the positive camber through coarse process；Being provided with expansion post on locking component, brake block is made up of two panels spring leaf, and brake block is pressed to positive camber and negative camber by the extruding expansion expanding post.
Further, described brake block is the lockup state implementing maintain during braking locking component, has the two panels spring leaf of auto-reset function when releasing braking.Described locking component moves around alignment pin, drives expansion post to snap in brake block.
In this utility model, having annular groove inside roller, groove positive camber processed to promote braking effect through coarse.Brake block is made up of two panels deformable spring leaf, leaves the space maintaining locking component locking inside spring leaf.Locking component is by stick and extends to the expansion post of both sides brake block and forms, and during locking, stick drives and expands post and snap in inside spring leaf, and spring leaf is expanded and pressed to roller outside it and realize self-locking.Brake block is that two panels spring leaf is constituted, and implements maintain during braking the lockup state of locking component, has auto-reset function when releasing braking.
This utility model has a beneficial effect highlighted below:
This utility model compact conformation, easy to operate, practical, can directly from different luggage cases with the use of, it is to avoid luggage case stress on automobile, train is arbitrarily slided, and being greatly improved trip convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is assembling figure of the present utility model；
In figure, 1-support, 2-brake block support, 3-locking component support, 4-wheel shaft, 5-roller, 6-Baltimore groove, 7-positive camber, 8-clamp nut, 9-locking component, 10-expands post, 11-alignment pin, 12-brake block, 13-rivet, 14-rivet hole, 15-dowel hole, 16-negative camber.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail:
Seeing Fig. 1, Fig. 2, the castor of a kind of band auto-lock function, including total support 1 and roller 5, total support includes brake block support 2, locking component support 3 and wheel shaft 4, and roller is installed on wheel shaft two ends by confining nut 8；Brake block support 2 is provided with rivet hole 14, is fixed on brake block support 2 by brake block 12 by rivet 13.Locking component support 3 is provided with dowel hole 15, is positioned on locking component support 3 by locking component 9 by alignment pin 11.Being provided with annular groove 6 inside roller, annular groove has negative camber 16 and the positive camber 7 through coarse process；Being provided with expansion post 10 on locking component 9, brake block is made up of two panels spring leaf, and brake block is pressed to positive camber and negative camber by the extruding expansion expanding post, can restore voluntarily without extruding.
When needing braking, being pressed downward against by locking component 9, locking component 9 drives expansion post 10 to move together, expands extruding brake block 12 both sides spring leaf after post 10 contacts brake block 12 and expands outwardly, presses to roller 5 inner concave groove curved surface 7, curved surface 16.Inside the profile of expansion post 10 and brake block, headspace adapts to maintain the lockup state of locking component 9.
When need not braking, upwards being lifted by locking component 9, locking component 9 drives expansion post 10 to move together, spins off in 12 liang of spring leafs of brake block.Brake block 12 restores to the original state, brake release.
