Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
The utility model provides a kind of pedal valve operating system with auto-lock function as Figure 1-4, including valve
Body 1, connecting plate 2, self-locking axis pin base 3, hook 4, pedal 5, connecting shaft 6, the first bearing pin 7, the second bearing pin 8, torsion spring 9, drawing
Spring 10, bearing 11 and hook axle 12 are stretched, the connecting plate 2 is bolted on valve body 1, and the self-locking axis pin base 3 leads to
Cross welding to be connected with connecting plate 2, the pedal 5 is fixed on connecting plate 2 by the first bearing pin 7, the pedal 5 and connecting plate 2
Between torsion spring 9 is housed, the one end of the torsion spring 9 is supported on the second bearing pin 8, and the outer ring of the bearing 11 passes through housing
It is fixed on pedal 5, inner ring and one end of connecting shaft 6 of the bearing 11 are fixed, the other end and the hook 4 of the connecting shaft 6
One end fix, it is described hook 4 the other end be connected with one end of extension spring 10, the other end of extension spring 10 is fixedly connected
In the second bearing pin 8, the hook axle 12 is fixed on self-locking axis pin base 3 by nut, and the activity point of view scope of the pedal 5 is
Between 0 °~27 °, the hook 4 is made up of the first bending 41, the second bending 42 and the 3rd bending 43, and hook 4 has three bendings,
The limited bit function of first bending 1, the second bending 2 be able to can be realized tightly with free switching self-locking and not self-locking state, the 3rd bending 3
Artificial self-locking in the case of urgency.
Operation principle：1st, self-locking releasing process, such as Fig. 1, the first bending 41 are in close contact with pedal 5, and pedal 5 is in moment of torsion bullet
Extreme higher position is under spring 9 and treadle valve contained spring force action, with foot pedal, pedal 5 is linked up with during down
4 contact with hook axle 12, and hook 4 rotates around bearing and connecting shaft 6, after pedal 5 turns over certain angle, in extension spring 10
It is suspended to automatically under effect on hook axle 12, treadle valve completes auto-lock process, now vehicle is in on-position, driver unclamps pin,
Pedal 5 will not rebound back home position, during unblock, while stepping at second bending 42 of hook 4 so that hook 4 opposite directions rotation
Turn, depart from hook axle 12, then loosen pedal 5 in the case where 4 rotation position now of hook is kept, pedal 5 is recovered former
Position, now links up with bending 1 and pedal and is in close contact, and completes releasing process, pedal 5 in the case where hydraulic coupling and torsion spring 9 are acted on from
Dynamic to spring back to such as Fig. 1, now vehicle releases braking action, 2, switching self-locking and not self-locking state, and a, self-locking state are switched to not
Self-locking state, such as Fig. 1 are self-locking state, and the first bending 41 on hook 4 is in close contact with pedal 5, in this case, is stepped on pin
Second bending 42 of hook 4, hook 4 rotates around bearing 11 and connecting shaft 6, when hook 4 turns over spring two fixing points and company
After the straight line that spindle is formed, under the effect of extension spring 10, hook 4 continues to rotate, and until lower end contacts with pedal 5, hook 4 is just
Stabilization is parked in the position, such as Fig. 3 sectional views, and now bending 1 is separated with pedal, and this state is not self-locking state, and routine is stepped on
Plate function is the same, and b, not self-locking state are switched to self-locking state, and such as Fig. 3 is not self-locking state, in this case, hook is stepped on pin
4 the 3rd bending 3, hook 4 rotates around bearing 11 and connecting shaft 6, when hook 4 turns over spring two fixing points and connecting shaft shape
Into straight line after, extension spring 10 effect under, hook 4 continue rotate, until bending 1 is in close contact with pedal 5, such as Fig. 1, just
Return to self-locking state, 3, in emergency circumstances artificial auto-lock process in emergency circumstances, when vehicle unexpected abnormality situation, injure and drive
The life security of the person of sailing, driver has little time to have other to operate again when, even if extension spring 10 is damaged, with a pin by pedal 5
Step on application position, hook bending 3 is stepped on another pin, hook 4 rotates around bearing 11 and connecting shaft 6, until hook 4 hangs over
On hook axle 12, treadle valve is to be capable of achieving self-locking, and now vehicle is in braking state, and driver unclamps pin, and pedal 5 will not also rebound
Home position is gone back to, this just realizes in emergency circumstances accomplishing that both safety parks cars, and can safely leave and drive again by operating pedal valve
Sail room.
