Description

Body overhang is put the S. A. Locking Device

Affiliated technical field

The utility model relates to automobile technical field, relates to a kind of operator's compartment body overhang and puts Locking Device.

Background technology

Present stage is mainly adopted the lockable mechanism of being made up of bar handle assembly-short rod-lock body-rod assembly-lock body, and is installed on the operator's compartment, opens motion with operator's compartment.During unlatching, open the position limit arm of bar handle assembly, manually spur latch hook, manually draw back hook with safety tong again, operator's compartment is unblanked; During locking, operator's compartment is left behind by manpower, hook with safety tong with after after hook on suspending hangs up, utilize bar handle to make latch hook locking, operator's compartment locking again.This Locking Device complex structure, complex operation, manufacturing cost height.

Summary of the invention

The utility model provides a kind of low cost of manufacture, simple and compact for structure, easy to operate body overhang to put the S. A. Locking Device in order to overcome the deficiencies in the prior art.

Suspend after the technical solution of the utility model comprises, hydraulic pressure is unblanked oil cylinder, latch hook, return lock spring, brace panel.After brace panel is arranged on suspending, the locking bar that latch hook passes brace panel and operator's compartment tail-bracket is hook mutually, latch hook lower end one bearing pin and the hydraulic pressure oil cylinder of unblanking flexibly connects; Return locking spring abutment is arranged on the latch hook, and the return lock spring is contained on the return locking spring abutment; Latch hook has guide groove, and guide finger is arranged in the guide groove.

The unblank piston rod head of oil cylinder of hydraulic pressure of the present utility model links to each other with the lower end of latch hook, and the unblank afterbody of oil cylinder of hydraulic pressure is put with body overhang through bearing pin and linked to each other.

There is the latch hook guide plate that is loaded on the brace panel lower end latch hook of the present utility model both sides, are fixed with the guide finger that passes guide groove on the latch hook guide plate.

Return lock spring of the present utility model can be stage clip or extension spring.

The utility model is oil cylinder because employing hydraulic pressure is unblanked, and opens Locking Device by hydraulic ram when unblanking; During locking, oil pressure unloading, the automatic locking of Locking Device under the effect of return lock spring.Compared with prior art, form a body overhang in suspending after the utility model is installed on the vehicle body lockable mechanism and put the locking assembly, convenient installation, locking, and simplified Locking Device, and reduced manufacturing cost, improved the reliability of vehicle body locking.

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.

Fig. 4 is the structural representation of the utility model embodiment 3.

Fig. 5 is the unlocking condition scheme drawing of embodiment 3.

Among the figure, suspend after 1.; 2. the oil cylinder of unblanking; 3. return is locked spring abutment; 4. latch hook; 5. return lock spring; 6. brace panel; 7. cushion rubber suspends behind the operator's compartment; 8. operator's compartment tail-bracket; 9. locking bar; 10. long lumbar hole; 11. guide finger; 12. guide groove; 13. latch hook guide plate; 14. bearing pin; 15. chassis side rail; 16. hydraulic pressure oil inlet and outlet; 17. bearing pin.

The specific embodiment

Among Fig. 1, Fig. 2, hydraulic pressure oil inlet and outlet 16 is arranged at the unblank afterbody of oil cylinder 2 of hydraulic pressure, the afterbody of the oil cylinder 2 of unblanking by bearing pin 14 with after suspend and 1 link to each other, the piston rod head of the oil cylinder 2 of unblanking links to each other with the afterbody of latch hook 4; Return lock spring 5 is a stage clip, and compression spring sleeve is contained on the latch hook 4, return locking spring abutment 3 and latch hook 4 weld togethers; Latch hook 4 middle parts have guide groove 12, and guide groove 12 is vertical long waist shaped, and there is the latch hook guide plate 13 that is loaded on brace panel 6 lower ends latch hook 4 both sides, are fixed with the guide finger 11 that inserts guide groove 12 on the latch hook guide plate 13; Latch hook 4 passes the horizontal long lumbar hole 10 of brace panel 6, with be fixed in operator's compartment tail-bracket 8 on locking bar 9 hook mutually, rely on side, the guide groove 12 in the latch hook 4, guide finger 11 guiding of the long lumbar hole 10 on the brace panel 6 during latch hook 4 motions, suspend after the utility model part concentrates in 1 inner chamber, put the locking assembly as body overhang and be contained on the chassis side rail 15.

Fig. 1 represents the locking state of embodiment 1, and Fig. 2 represents the unlocking condition of embodiment 1.

When hydraulic oil enters the oil cylinder 2 of unblanking through oil inlet and outlet 16, piston rod promotes latch hook 4, and latch hook 4 is subjected to the spacing and guiding in the side of long lumbar hole 10 on guide groove 1, guide finger 11 and the brace panel 6, do and rise and yaw motion, leave the locking bar 9 on the operator's compartment tail-bracket 8, at this moment, vehicle body enters released state; When unblanking oil cylinder 2 off-loads, the oil pressure of the oil cylinder 2 of unblanking descends, and piston rod thrust also reduces thereupon, and piston rod is return under the effect of return lock spring 5, opposite motion when driving latch hook 4 and doing with release, and operator's compartment enters locking state.
