Abstract
The invention discloses a trundle with a self-locking function. The trundle comprises a general stand and rollers. The general stand comprises a brake pad support, a locking component support and an axle. The rollers are mounted at the two ends of the axle; a brake pad is fixed to the brake pad support through rivet holes and rivets; a locking component is arranged on the locking component support through locating pin holes and locating pins; an annular groove is formed in the inner side of each roller and provided with a negative camber and a roughened positive camber; an expansion pillar is arranged on the locking component, the brake pad is composed of two leaf springs, and the brake pad expands to press the positive camber and the negative camber under the extrusion of the expansion pillar. The trundle is compact in structure, convenient to operate, high in practicability and capable of being used directly in cooperation with different suitcases, it is avoided that the suitcases are stressed to slide randomly on a car or train, and convenience for travel is greatly improved.
Description
Technical field
The present invention relates to small stores technical field, specifically a kind of castor with auto-lock function.
Background technology
Luggage case is applied widely in trip, and the life with people is closely bound up.Holding article, while liberation both hands, it have 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, it is necessary to hand steered or fallen by luggage case or be sidelong, luggage case stress arbitrarily moves the safety being also unfavorable for driving.
Summary of the invention
For above-mentioned deficiency of the prior art, it is an object of the invention to provide a kind of castor with 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 is greatly improved trip facility.
It is an object of the invention to be achieved through the following technical solutions:
A kind of castor with auto-lock function, it is characterised in that: this castor includes total support and roller, and described total support includes 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 can maintain the lockup state of locking component when being and implement braking, 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 the present invention, 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 can maintain the lockup state of locking component, have auto-reset function when releasing braking when implementing braking.
The present invention has beneficial effect highlighted below:
Present configuration is compact, easy to operate, practical, it is possible to directly with different luggage cases with the use of, it is to avoid luggage case stress on automobile, train is arbitrarily slided, and is greatly improved trip convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the assembling figure of the present invention;
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 drawings and Examples, the invention will be further described:
Referring to Fig. 1, Fig. 2, a kind of castor with 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 to brake, 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 brake, 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.
