Detailed description of the invention
Referring to figs. 1 through Fig. 8, the utility model embodiment Castor for trunk or bag 2 is described further.
As shown in Figure 1 and Figure 4, a kind of Castor for trunk or bag 2, the castor 2 comprising support 1 and be rotationally connected with it, support 1 is provided with mounting hole 3, the pressing lever 4 that be connected flexible with support 1 is provided with in mounting hole 3, pressing lever 4 is removably connected with and tramples block 6, clamping block 61 is arranged to be trampled on block 6, and castor 2 is provided with the blocked hole 21 coordinated with clamping block 61.
As shown in Figure 5-Figure 7, the turning block 5 of conflicting with pressing lever 4 is provided with in mounting hole 3, mounting hole 3 upper inside wall is interval with projection 31, turning block 5 is provided with guide block 51, guide block 51 rotate motion block 5 even circumferential distribution, the guide groove 34 for guide block 51 slippage is formed between adjacent projections 31, the cavity volume 32 rotated for turning block 5 is formed between projection 31 and mounting hole 3 diapire, actuator is provided with between turning block 5 and mounting hole 3 diapire, actuator drives pressing lever 4 reset and drive turning block 5 to rotate in cavity volume 32, projection 31 is provided with the draw-in groove 33 with guide block 51 clamping of turning block 5.
Wherein actuator is elastic component, elastic component one end and tumbler are conflicted, the other end and mounting hole 3 diapire are conflicted, preferably this elastic component is spring 7, pressing lever 4 is provided with the conflict block 41 of conflicting with turning block 5, and conflict block 41 is around the distribution of pressing lever 4 even circumferential, and conflict block 41 is provided with oblique surface a42, guide block 51 is provided with the oblique surface b52 coordinated with oblique surface, specifically sees Fig. 5.
Concrete operating process is as follows: trample block 6 by arranging on pressing lever 4, and trample block 6 and removably connected by pin 9 with pressing lever 4, wherein clamping block 61 is arranged and the both sides of trampling block 6, described castor 2 is provided with the blocked hole 21 coordinated with clamping block 61, clamping block 61 coordinates with blocked hole 21 and realizes screens, and then the rotation of restriction castor 2 realizes the function of brake, when needs promote case and bag, pin is stepped on pedal and pressing lever 4 is pressed down, and then clamping block 61 is deviate to remove spacing from blocked hole 21, by arranging guide block 51 and arrange projection 31 at mounting hole 3 inwall on turning block 5, and then can ensure that turning block 5 can only move axially on mounting hole 3 top, promote turning block 5 to be displaced downwardly to after in cavity volume 32 when pressing lever 4 presses down, due to the setting of oblique surface b52 and oblique surface c311, spring 7 can resolve into the power of circumference to the axial force of turning block 5, and then turning block 5 rotation can be driven to make guide block 51 and draw-in groove 33 clamping realize spacing, when needs brake, only need step on pedal again makes pressing lever 4 move down, and then promote turning block 5 and move down guide block 51 is deviate from from draw-in groove 33, under the effect of spring 7, the position as guide groove 34 correspondence is rotated further after deviating from, pressing lever 4 and turning block 5 can upward sliding homing realize braking to clamping block 61 and blocked hole 21 clamping under actuator effect, thus realize brake and the switching of rolling.
The whole handoff procedure of above-mentioned brake is simple and convenient, only need continuous pin to step on pedal just can realize switching, and the brake structure of Castor for trunk or bag 2 is the realization of pure mechanical drive, does not have piston/cylinder, stop cylinder body and fluid etc., and then structure is simple and productive costs is low, be suitable for producing in enormous quantities.
As shown in Figure 3, blocked hole 21 runs through near side, castor 2 center of circle, blocked hole 21 distributes around castor 2 even circumferential, such one side can make clamping block 61 can snap in blocked hole 21, on the other hand when needs brake, all there is corresponding blocked hole 21 can directly and clamping block 61 clamping when no matter where castor 2 turns to, more convenient.
Gib block 43 is provided with as shown in Figure 4 on pressing lever 4, mounting hole 3 inwall is provided with the guide groove coordinated with gib block 43, and then the axial motion that pressing lever 4 is stable can be ensured, avoid gathering at motion process occurring that rotating the situation causing oblique surface b52 and oblique surface c311 to overlap very well occurs, increases the run stability of total.
As shown in Figure 7, projection 31 bottom surface is the oblique surface c311 fitted with oblique surface b52, and under spring 7 application force, turning block 5 is more prone to rotation and slips in draw-in groove 33 like this, projection 31 bottom surface also can be avoided the wearing and tearing of oblique surface b52 simultaneously, increase the service life, and total running is more smooth.
The damage of the parts such as spring 7 or turning block 5 is there will be unavoidably in permanent use procedure, and then need to change, as shown in Figure 8, run through bottom mounting hole 3, be provided with sprue 8 bottom mounting hole 3, sprue 8 and support 1 are removably connected by pin 9, be convenient to the damage parts taken out in mounting hole 3 like this change, only pin 9 need be pulled down, go lower sprue 8 just can realize maintain and replace, convenient to operation.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
