The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
See shown in the accompanying drawing 1～5 that the brake wheel arrestment mechanism of luggage case described in the utility model comprises pull bar 10 and relevant brake wheels (not shown), pull bar 10 is the flexible body of rod of being made up of interior pipe and outer tube, uses to reach to stretch, and shrinks the effect of depositing.The backguy 20 of one interlock brake wheel brake block laterally runs through pull bar 10, and in the present embodiment, what backguy 20 ran through is the outermost tubes of pull bar 10, and backguy 20 middle part in pull bar 10 is formed with a bridge formation section 21.Valve jacket coated outside backguy 20 outside pull bar 10 had, and the shell cover has protection and effect attractive in appearance, and backguy 20 is stretched in the valve jacket outside; Be combined with a protection 22 in backguy 20 and pull bar 10 places of touching, protect 22 and be placed on the pull bar 10.In the present embodiment, in order to cooperate installation, offer irregularly-shaped hole 11 on the pull bar 10, the convenient protection of the macropore of irregularly-shaped hole 11 upper ends 22 wears, and the convenient protection of the aperture of irregularly-shaped hole 11 lower ends 22 card are established and fixed.
One sliding seat 30 is arranged on middle part in the pull bar 10, and is positioned at bridge formation section 21 tops of backguy 20, and sliding seat 30 can press down the bridge formation section 21 of backguy 20 by contracting promotion in the pipe within the pull bar 10, takes this to reel backguy 20 and the braking brake wheel.Backguy 20 overhanging two ends are respectively to connect the brake block on the brake wheels about luggage case, brake block and wheel can adopt friction brake or blocking brake, brake as modes such as similar bicycle or motorcycles, certainly also be not limited to this, all can so long as can reel the structure that action drives braking brake by backguy.
Sliding seat 30 is a flexible contact 31 with bridge formation section 21 parts that contact roof pressure of backguy 20, and the roof pressure end of flexible contact 31 is provided with the bridge formation section 21 that an arc groove 311 is clamped down on backguy.In the present embodiment, it is ccontaining for flexible contact 31 that sliding seat 30 is provided with a shape groove 32, flexible contact 31 is articulated on the sliding seat 30 by the protruding axle 312 on its side, and there is vertical elongated slot 33 that protruding axle 312 spaces that move up and down of flexible contact 31 are provided on the sliding seat 30, flexible contact 31 the inners are shaped to bearing pin and socket one compression spring 34, compression spring 34 provides flexible contact 31 vertical unsteady characteristics, the protruding axle 312 of flexible contact 31 has the effect of guiding and 31 activities of restriction flexible contact, flexible contact 31 is under the elastic reaction that provides of compression spring 34, and it has when touching with bridges formation of backguy 20 sections 21 and cushions and shockproof effect.
Fig. 6,7 is depicted as the situation that the utility model is used to brake, wherein Figure 6 shows that general normal braking situation, the promotion sliding seat 30 that contracts in the corresponding interior pipe by pull bar 10 moves down, thereby make sliding seat 30 press down the bridge formation section 21 of backguy 20, build bridge section 21 deformation and reel backguy 20, drive the corresponding brake block of brake wheel thus by backguy 20, realize the brake purpose.Figure 7 shows that the view when the brake load is excessive, at this moment flexible contact 31 is stressed excessive and contract in sliding seat 30, buffering contracts in compression spring 34 gives, and the protruding axle 312 of flexible contact 31 is guided, guarantee that flexible contact 31 contacts steadily with the bridge formation section 21 of backguy 20, thereby reel backguy 20 well.There is an arc groove 311 to clamp down on backguy 20 on the roof pressure end of flexible contact 31, can prevents to skid, strengthen flexible contact 31 and contact with backguy 20.The bridge formation section 21 that the utility model utilizes sliding seat 30 to press down backguy 20 just reels backguy 20, drive brake block by backguy 20 again and prevent the luggage case wheel, and brake and pull bar 10 contraction phases coupling, be that pull bar 10 is regained then corresponding prevention wheel, the location so that luggage case is stood, be unlikely to random slippage, the embarrassing incident of avoiding luggage case to slip unintentionally.And pull out pull bar 10, and then unclasping sliding seat 30, the bridge formation of backguy 20 section 21 resets and lifts sliding seat 30 stretching the time, so that the usefulness of brake next time; Backguy 20 resets and then decontrols the luggage case wheel, and promptly the user can pull and support luggage case and moves, and is convenient for carrying luggage.
Among the figure, sliding seat 30 is provided with elasticity button 35 and locatees with the button hole 12 on pull bar 10 relevant positions.Elasticity button 35 on the sliding seat 30 is symmetrically distributed, and one of them is a round steel pearl, and another is a protruding pin, and both are installed in the corresponding groove cave, and has the compression spring to support.Shown in Figure 2, elasticity for the protruding pin type buckles 35, its mode of utilizing the inclined-plane to cooperate is controlled flexible, promptly be provided with the inclined-plane at the protruding pin middle part, on sliding seat 30, be provided with the push rod 36 that can mate this inclined-plane action, push rod pushes away for 36 times and then utilizes inclined-plane relation that protruding pin type elasticity is buckled 35 to push back, i.e. indentation is triped and allowed sliding seat 30 to move up and down, and the pressing action of push rod 36 can be by the driving of contracting in the pipe in pull bar 10 corresponding; Push away sliding seat 30 for 35 needs of elasticity button of round steel pearl under firmly and can realize triping, simple in structure, easy to operate.
In the utility model, the only top 37 that also being provided with on the sliding seat 30 glides puts in place, only interior protuberance 13 cards of top 37 and pull bar 10 relevant positions are only.This structure is determined the amplitude that sliding seat 30 moves down, and has positioning action, and it is excessive to prevent that sliding seat 30 from pressing down.Present embodiment, the screw that the interior protuberance 13 of pull bar 10 is locked by an outside constitutes, thereby simplifies processing structure, is convenient to make.
