The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done to describe further through embodiment.
Embodiment:
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the hand brake operation mechanism that is used for fork truck comprises handle sleeve 3, and handle sleeve 3 tops are set with handle 2, are provided with pull bar 10 in the handle sleeve 3; The top of pull bar 10 is arranged with retracing spring 14; The upper end is connecting release knob 1; The last end in contact of the lower end of release knob 1 and retracing spring 14, handle sleeve 3 bottoms have the lock buckling groove of axial perforation, also are being connected the drag-line link plate 6 of clamping plate shape with the cooresponding handle sleeve of lock buckling groove 3 bottoms; Drag-line link plate 6 is made up of two set squares, and bottom is provided with quadrant 13 through spacing bearing pin 12 in it; The upper end of quadrant 13 is the flank of tooth; Be provided with snap close 11 with cooresponding drag-line link plate 6 internal upper parts of quadrant 13 flank of tooth through bearing pin, snap close 11 is a lath-shaped, and an end is the tooth button that cooperates with quadrant 13 flank of tooth; The other end stretches in the lock buckling groove of handle sleeve 3, and is connecting the lower end of pull bar 10; The bottom of quadrant 13 extends drag-line link plate 6 outsides, and overhanging end one side of quadrant 13 bottoms is connecting switch seat 9, and switch seat 9 is provided with micro-switch 8, is provided with baffle plate 7 with micro-switch 8 cooresponding drag-line link plates 6 one sides; The outer side edges middle part and the bottom of quadrant 13 are respectively equipped with the installation projection, install on the projection for every and all offer mounting hole.
The installation projection of quadrant 13 middle parts and bottom is crooked to both sides respectively, makes every rectangular shape between projection and the quadrant 13 is installed.
The principle of work of the utility model is following:
During installation, quadrant 13 is fixed on the fork truck car body.When car load needs braking during standstill; Chaufeur drives handle sleeve 3 and rotates around spacing bearing pin 12 with drag-line link plate 6 through pulling handle 2, and drag-line link plate 6 drives the brake cable pull upward movement; Simultaneously; Pull bar 10 drives snap close 11 and rotates around spacing bearing pin 12, and snap close 11 forms interlocking with quadrant 13, realizes the stopping brake of car load.When chaufeur need unclamp when hand braking, must realize releases through pull bar 10 and snap close 11 through pressing unlock button 1, unclamp unlock button 1, retracing spring 14 resets unlock button, realizes removing the stopping brake of car load; Simultaneously, the utility model is through the effect of 7 pairs of micro-switchs 8 of baffle plate, and synchronously to the cut-out control of car load electric system, actv. prevents that chaufeur from making the car load operation under the hand braking situation of leaving behind when being implemented in mechanical parking.
Through the groove roll extrusion of handle sleeve 3 is handled, actv. prevents the phenomenon that handle 2 long-time uses come off easily, and the boss of roll extrusion simultaneously is as the confined planes of retracing spring 14, simple and reliable process, cost reduction; Spacing bearing pin 12 also can be through setting up the lateral clearance of nut 5 control handles except the effect that realizes bearing pin.
Fig. 5 and hand braking handle structure level land and the grade braking view of being respectively shown in Figure 6.Because snap close 11 can both be realized interlocking with each the ratchet position on the quadrant 13, when fork truck is parked on the ramp, sees Fig. 6; The stopping brake moment that needs is bigger, and chaufeur is through increasing hand braking actuating force, and when on the level land, stopping; See Fig. 5; Chaufeur can be used less hand braking actuating force, realizes that chaufeur parking on different road conditions needs different parking actuating forces, reduces the labour intensity of chaufeur.In the time of simultaneously also realizing brake wear, the self-locking position that changes snap close 11 and quadrant 13 is realized the emergency of fork truck, need not the gap of artificial adjustment drg.
