Abstract
The utility model relates to an automotive traffic safety device, in particular to an automobile seat backrest lock, which comprises lock frames, a lock cylinder, a lock cylinder rivet and a lock frame bolt sleeve, wherein the lock cylinder is fixed between two lock frames through the rivet, and the lock frame bolt sleeve is a hollow tube, and is located below the lock cylinder and fixed between the two lock frames. The safety and the durability of the backrest lock are largely increased after utilizing the safety device. Further, by utilizing a multi-plate structure, stress of the safety device can not be concentrated excessively, thereby guaranteeing the lock body to have higher strength.
Description
Technical field
The utility model relates to the running safety device, relates in particular to a kind of motor vehicle seat back lock.
Background technology
At present, have relatively high expectations for the multifunctionality of vehicle in market, for the automobile-used family of most of mixed-traffic logistics, wishes that seat has the turnover function, and good comfort is arranged on taking simultaneously again, and guarantee fixing reliable.Present backrest lock, intensity is lower, and endurance quality is not high, can produce after the long-term use and become flexible, even it is damaged to lose efficacy.
Summary of the invention
The utility model provides a kind of backrest of folding seat that makes fixing reliable, safe, all better motor vehicle seat back lock of intensity and endurance quality at the deficiencies in the prior art.
The technical solution of the utility model is: a kind of motor vehicle seat back lock, comprise lock frame, lock core, Lock rivet, lock frame bolt collar, lock core is fixed between the two mortice lock frames by rivet, and lock frame bolt collar is a hollow tubular, be in the below of lock core, and be fixed between the two mortice lock frames.Lock core is made up of ratchet, ratchet shaft, ratchet, pawl axis, ratchet pull back spring, ratchet pull back spring, lock housing, ratchet and pawl is connected on the lock housing by ratchet shaft and pawl axis respectively, ratchet pull back spring and ratchet pull back spring twine respectively and are installed on ratchet shaft and the pawl axis, ratchet pull back spring one end is buckled on the ratchet, and the other end is buckled on the lock housing; Ratchet pull back spring one end is buckled in the tail end place of ratchet, and the other end is buckled on the lock housing.
Ratchet is provided with outer ratchet projection, ratchet breach and handle ratchet wheel projection, ratchet is provided with ratchet hook, ratchet tail end, drawstring adapter plate and drawstring, the ratchet hook matches with outer ratchet convex shape, and the drawstring adapter plate is connected ratchet tail end place, and drawstring is fixed on the drawstring adapter plate.Ratchet and ratchet adopt the structure of double-layer overlapping.
The utility model passes lock frame bolt collar by bolt, will lock frame and be fixed on the automotive seat.During unlocking condition, because the effect of ratchet pull back spring, the ratchet breach is to be in opened state.When lock bolt bump ratchet breach, the handle ratchet wheel projection is produced application force, the promotion ratchet clockwise rotates, when outer ratchet projection turns to when contacting with the ratchet hook, outer ratchet projection promotes the ratchet hook and also clockwise rotates, after turning over certain angle, outer ratchet projection is crossed the ratchet hook, and ratchet is hooked under the effect of ratchet pull back spring outer ratchet projection button is dead, reaches locked state.
During release, the pulling drawstring drives ratchet by the drawstring adapter plate and clockwise rotates, turn over certain angle after, ratchet hook and the disengaging of outer ratchet projection.Ratchet is left-hand revolution under the application force of ratchet pull back spring, gets back to released state.After unclamping drawstring, ratchet is got back to initial condition under the effect of ratchet pull back spring.So far, finished entire work process of the present utility model.
Adopt after the structure of the present utility model, the safety and the durability of backrest lock all are greatly improved, and owing to adopt multi-sheet structure, stress can be too unconcentrated, thereby guarantee that lock body has higher intensity.

Among the figure, lock frame A, lock core B, Lock rivet C, lock frame rivet sleeve D, ratchet 1, ratchet shaft 2, ratchet 3, pawl axis 4, ratchet pull back spring 5, ratchet pull back spring 6, lock housing 7, lock bolt 8, outer ratchet projection 11, ratchet breach 12, handle ratchet wheel projection 13, ratchet hook 31, ratchet tail end 32, drawstring adapter plate 33, drawstring 34.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.
A kind of motor vehicle seat back lock, comprise lock frame A, lock core B, Lock rivet C, lock frame rivet sleeve D, between the two mortice lock frame A, lock frame rivet sleeve D was a hollow tubular before and after lock core B was fixed on by Lock rivet C, be in the below of lock core B, and be fixed between the two mortice lock frame A.Lock core B is made up of ratchet 1, ratchet shaft 2, ratchet 3, pawl axis 4, ratchet pull back spring 5, ratchet pull back spring 6, lock housing 7.Ratchet 1 and ratchet 3 are connected on the lock housing 7 by ratchet shaft 2 and pawl axis 4 respectively.Ratchet pull back spring 5 and ratchet pull back spring 6 twine respectively and are installed on ratchet shaft 2 and the pawl axis 4.Ratchet pull back spring 5 one ends are buckled on the ratchet 1, and the other end is buckled on the lock housing 7; Ratchet pull back spring 6 one ends are buckled in the tail end place of ratchet 3, and the other end is buckled on the lock housing 7.
Ratchet 1 is provided with outer ratchet projection 11, ratchet breach 12 and handle ratchet wheel projection 13; Ratchet 3 is provided with ratchet hook 31, ratchet tail end 32, drawstring adapter plate 33 and drawstring 34, and ratchet hook 31 matches with outer ratchet projection 11 shapes; Drawstring adapter plate 33 is connected ratchet tail end 32 places, and drawstring 34 is fixed on the drawstring adapter plate 33.Ratchet 1 all is the structure of double-layer overlapping with ratchet 3.
The utility model passes lock frame rivet sleeve D by bolt, will lock frame A and be fixed on the automotive seat.During unlocking condition, because the effect of ratchet pull back spring 5, ratchet breach 12 is to be in opened state.When lock bolt 8 bump ratchet breach 12, handle ratchet wheel projection 13 is produced application force, promoting ratchet 1 clockwise rotates, when outer ratchet projection 11 turns to when contacting with ratchet hook 31, outer ratchet projection 11 promotes ratchet hooks 31 and also clockwise rotates, turn over certain angle after, outer ratchet projection 11 is crossed ratchet hook 31, ratchet hook 31 toward back rotation, with outer ratchet projection 11 buttons extremely, reaches locked state under the effect of ratchet pull back spring 6.
During release, pulling drawstring 34 drives ratchets 3 by drawstring adapter plate 33 and clockwise rotates, turn over certain angle after, ratchet hook 31 and outer ratchet projection 11 disengagings.Ratchet 1 is left-hand revolution under the application force of ratchet pull back spring 5, gets back to released state.After unclamping drawstring 34, ratchet 3 is left-hand revolution under the effect of ratchet pull back spring 6, gets back to initial condition.So far, finished entire work process of the present utility model.
