The another purpose of the utility model is to provide a kind of brake crank simple, easy to assembly of making.

The technical scheme that the utility model adopts is: a kind of brake crank; Comprise main body, handle and trigger, wherein, this main body one end is provided with the articulated section; The other end of this main body is provided with sliding surface and the position-limited trough that sets to the concave of this sliding surface certainly; This handle is provided with drive-connecting shaft, and this drive-connecting shaft is articulated on the articulated section of this main body, and this handle is provided with the solidus groove that is used for fixing brake cable.

This handle also is provided with the hinge hole that is used to install trigger; This trigger is hinged in the hinge hole of this handle by set pin; This trigger is provided with the screens end that can be connected to this position-limited trough towards an end of this main body; The other end of this trigger is provided with the press section, between this trigger and this handle pull back spring is installed, and this pull back spring is socketed in this set pin.

This main body also is fixedly connected with locking block.

The beneficial effect of the utility model is: the utility model structurally comprises main body, handle and trigger; Wherein, This main body one end is provided with the articulated section, and the other end of this main body is provided with sliding surface and the position-limited trough that sets to the concave of this sliding surface certainly, and this handle is provided with drive-connecting shaft; This drive-connecting shaft is articulated on the articulated section of this main body, and this handle is provided with the solidus groove that is used for fixing brake cable.This handle also is provided with the hinge hole that is used to install trigger; This trigger is hinged in the hinge hole of this handle by set pin; This trigger is provided with the screens end that can be connected to this position-limited trough towards an end of this main body; Solve and exist in the present technology, the brake crank that need continue to hold with a firm grip could be realized the effect that boosted vehicle such as restriction wheelchair moves, and its handle can't be returned to initial location status under the position-limiting action of trigger; Realize to continue to realize the effect of brake after the operator unclamps handle, and do not need to install additional in addition the brake gear of location.

The specific embodiment

Extremely shown in Figure 6 like Fig. 1 is a kind of preferable practical implementation example of the utility model, and a kind of brake crank is as shown in Figure 1; Comprise main body 10, handle 20 and trigger 30, wherein, as shown in Figure 2; These main body 10 1 ends are provided with articulated section 11, and the other end of this main body 10 is provided with sliding surface 12 and the position-limited trough 13 that sets to the concave of this sliding surface 12 certainly, and is as shown in Figure 3; This handle 20 is provided with drive-connecting shaft 21; This drive-connecting shaft 21 is articulated on the articulated section 11 of this main body 10, so that this handle 20 can be that rotate in the axle center with this drive-connecting shaft 21, this handle 20 is provided with the solidus groove 22 that is used for fixing brake cable A; So that this handle 20 is being when the axle center is rotated with this pivotal axis 21, the action that these solidus groove 22 stretchy brake cable are braked.

As shown in Figure 3; This handle 20 also is provided with the hinge hole 23 that is used to install trigger 30, and this trigger 30 is hinged in the hinge hole 23 of this handle 20 by set pin 31, and this trigger 30 as shown in Figure 1 is provided with the screens end 32 that can be connected to this position-limited trough 13 towards an end of this main body 10; The other end of this trigger 30 is provided with press section 33; Like Fig. 3, shown in Figure 5, between this trigger 30 and this handle 20 pull back spring 34 is installed, this pull back spring 34 is socketed in this set pin 31.

When hold with a firm grip this handle 20 and when carrying out brake of operator; This trigger 30 is followed this handle 20 and is moved; Meanwhile the screens end 30 of this trigger 30 slides in the position-limited trough 13 from the sliding surface 13 of this main body 10, and this moment, the operator can unclamp handle 20, and this handle 20 can't be returned to initial location status under the position-limiting action of this trigger 30; Realize to continue to realize the effect of brake after the operator unclamps handle, and do not need to install additional in addition the brake gear of location.

Further, shown in Figure 1, this main body 10 also is fixedly connected with locking block 14, and this locking block 13 cooperates this main body that the utility model integral locks is fixed on the respective fixation post A of wheelchair, perambulator.

What deserves to be mentioned is, be socketed in this set pin, be used to the spring groove that card is established spring accordingly and in the main body of this utility model, trigger, be provided with, and this is the technology that is prone to think of for those skilled in the art, repeats no more at this in order to make this pull back spring.
