The specific embodiment
With reference to each accompanying drawing, disclosed the embodiment that this utility model old man helps step car brake mechanism, it includes: brake control group 2, brake group 3, handle 4, help step car skeleton 10, handspike 11, foot lever 12, wheel 13, pull bar 20, holder 21, drive rod 22, movable block 23, elastic parts 24, primary importance 30, brake line 31, deceleration handbrake lever 32, fixedly handbrake lever 33, extension spring 34, the second position 40, the 3rd position 50, brake tooth 131, cover tire 132, projection 211, pivoting point 212, long slot bore 221, press piece 321, brake block 331.
With reference to figure 1 and Fig. 2, disclose this utility model old man and helped step car brake mechanism to apply to an embodiment who helps step car skeleton 10, its effect system allows user can finish different control brake operations with one hand.This helps step car skeleton 10, includes a handspike 11 and a pair of foot lever 12.In the middle of present embodiment, handspike 11 slightly is the ㄇ font and grips for the operator, and foot lever 12 lower ends system articulates wheel 13; Be provided with brake tooth 131 in wheel 13 1 sides, its cover tire 132 can be a kind of soft rubber material.
Please refer to shown in Fig. 2,4, a pair of brake control group 2 is installed on the both sides of described handspike 11 respectively, connects a pull bar 20 between the two brake control groups 2.Each brake control group 2 comprises a holder 21, a drive rod 22, a movable block 23.
Holder 21 is for the both sides of being fixed in hand push frame 11, and is provided with projection 211 with extending.
Drive rod 22 1 ends are provided with a long slot bore 221, and are articulated in by long slot bore 221 on the pivoting point 212 of holder 21.Drive rod 22 other ends then are connected with an end of pull bar 20, in order to the pulling of mat pull bar 20 drive rod 22 are rotated.
Movable block 23 is articulated on the drive rod 22 and moves thereupon.In being provided with elastic parts 24 between movable block 23 and the drive rod 22 in order to keep movable block 23 vertical with drive rod 22.
Please continue with reference to the brake group 3 shown in the figure 3,4, be the lower end that is installed on foot lever 12, contains a brake line 31 and be connected between drive rod 22 and the brake group 3.Brake group 3 comprises a deceleration handbrake lever 32, fixedly handbrake lever 33, an extension spring 34.
Deceleration handbrake lever 32 is articulated in foot lever 12 lower ends that help step car skeleton 10, and an end then is connected with brake line 31, mat brake line 31 pulling and rotate.Deceleration handbrake lever 32 other ends connect one and press piece 321, but mat presses piece 321 and presses with the cover tire 132 of wheel 13 and contact when the line 31 of being braked turns.
Fixedly handbrake lever 33, are articulated in the opposite side of foot lever 12 lower ends, articulate and interlock with deceleration handbrake lever 32.Fixedly but the other end of handbrake lever 33 is provided with the brake block 331 of a clip in the brake tooth 131 of wheel 13.
Extension spring 34 is connected between foot lever 12 and the brake group 3.For example make it to be connected in the deceleration handbrake lever 32 of brake group 3 or fixing handbrake lever 33.
By the combination of above-mentioned member, the drive rod 22 of brake control group 2 can be moved to a primary importance 30, the second position 40 and one the 3rd position 50.When moving to primary importance 30, the drive rod 22 of brake control group 2 slightly is level, and the brake block 331 that presses piece 321 and fixing handbrake lever 33 of the deceleration handbrake lever 32 of brake this moment group 3 is all away from wheel 13 cover tires 132 and brake tooth 131, and wheel 13 is free to rotate.
Drive rod 22 can be moved upward to the second position 40, and the handbrake lever 32 that at this moment slows down is spurred and makes and press piece 321 and press in wheel 13 cover tires 132, uses to make wheel 13 slow down or stop.
Drive rod 22 can be moved downward to the 3rd position 50, makes fixedly that handbrake lever 33 is subjected to the pulling of extension spring 34 and brake block 331 is entered in the brake tooth 131 of wheel 13, uses making wheel 13 enter definite brake state.
Please consult shown in Fig. 5, when drive rod 22 was moved to primary importance 30, drive rod 22 withstood on because of movable block 23 on the projection 211 of holder 21 and remains in the primary importance 30 that slightly is level.At this moment, long slot bore 221 upper ends of drive rod 22 and holder 21 pivoting points 212 articulate, and the fixedly handbrake lever 33 of brake group 3 is spurred and keeps breaking away from the brake tooth 131 of wheel 13, thus wheel 13 free rotation.
Please consult shown in Fig. 6, when above-mentioned drive rod 22 upwards is pulled to the second position 40 by primary importance 30, with the pivoting point 212 of holder 21 is that the center pivots, and pulling brake line 31 and turn deceleration handbrake lever 32 up makes to press piece 321 and press in wheel 13 cover tires 132 and produce the effect of slowing down.
When decontroling drive rod 22, the handbrake lever 32 that then slows down is rotated in the opposite direction by the elasticity of extension spring 34,22 of drive rods must return back to primary importance 30 by the second position 40, deceleration handbrake lever 32 press 321 of pieces away from wheel 13 cover tires 132, wheel 13 freely rotate again.
Please continue and consult shown in Fig. 7,8, when drive rod 22 is driven and rotates, move to the 3rd position 50 by primary importance 30, drive rod 22 is that projection 211 contact points according to described movable block 23 and holder 21 are that rotate on the summit, the long slot bore 221 of drive rod 22 moves to downside by upside, make movable block 23 break away from described projection 211 contacts, make brake line 31 no longer hold brake group 3 owing to drive rod 22 moves down.At this moment, extension spring 34 pullings fixedly handbrake lever 33 are rotated, make fixedly the brake block 331 of handbrake lever 33 enter wheel 13 brake teeth 131 rotationally, thereby produce the effect of brake, and make drive rod need not add external force just can to remain in the 3rd position 50 in order to the rotation of limiting wheel 13.
When operator's desire is removed fixing brake, can spur drive rod 22 again and make with pivoting point 212 be upwards pivot of center, move to primary importance 30 by the 3rd position 50.This moment, drive rod 22 was via the fixing brake block 331 of handbrake lever 33 of brake line 31 pulling, cause brake block 331 thereby separating wheel 13 brake tooth 131, remove to fix and brake.
In the middle of the present embodiment, described pull bar 20 is the drive rod 22 that connects both sides, be displaced into first, second and the 3rd position 30,40,50 to provide the operator to spur described drive rod 22 simultaneously, be temporary transient brake, remove brake and fixing brake state with control brake group 3 by pull bar 20.
See also shown in Figure 9ly, drive rod 22 1 ends extend handle 4.User can directly be controlled brake group 3 by handle 4, selects simply to help the step car to do temporary brake or deterministic brake to the old man.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of this utility model certainly with this, and therefore the equivalent variations of being done according to this utility model claim still belongs to the scope that this utility model is contained.
