Abstract

The utility model discloses a lifting mechanism for a child safety seat base. The lifting mechanism for the child safety seat base is mainly used for enabling the child safety seat base installed on an automobile seat to have the lifting function, so that the requirement for seat back angle adjustment of a child safety seat is met, and a child sits on the automobile seat conveniently and feels comfortable. According to the structure, the lifting mechanism for the child safety seat base is composed of a body, a bottom board, a fixing base, a lifting handle, a compression spring and the like. The lifting mechanism is assembled or disassembled mainly through the method that multiple locking teeth on the rear side face of the fixing base are meshed with locking blocks on the front side face of the lifting handle, so that the height of the body relative to the bottom board is locked and lifting adjustment is achieved. The lifting mechanism of the improved structure further has the advantages of being simple in design, convenient to operate, reliable in adjustment and the like.

Description

Base of children safety seat lifting mechanism

Technical field

The utility model relates to the base lifting mechanism in the virgin product of a kind of baby, specifically refers to base of children safety seat lifting mechanism.

Background technology

Children often need to install child safety seat in the time riding in an automobile trip on automotive seat; it is a kind of for the comfortable virgin equipment of baby of taking and having safe constraint function of children; in order to adapt to all ages and classes section children's use needs, conventionally the chair back of safety seat can be designed to the adjustable structure of angle.But in practical operation, the angular adjustment of the chair back is often subject to the space constraint of automotive seat, therefore its angle that can regulate is conditional, often there will be regulating mechanism to be adjusted to extreme end, and the also desirable situation about using of out of reach of the angle of inclination of the chair back.Disclosed China Patent No. is " a kind of arrangement for adjusting height of automobile children safety chair base " that 200920199358.6 " a kind of base of automobile children safety chair " and disclosed China Patent No. are 200920200913.2, the disclosed technical scheme of these two patents is all design height adjustment structure on base, because regulating, the height of base is not subject to the space constraint of automotive seat, therefore can make the chair back of safety seat reach good result of use.Simultaneously, with respect to the virgin produce market of whole baby, at present less for the lift in height regulating mechanism design on base, on whole market, be applied in product on child safety seat for base adjusting mechanism also very rare, cannot meet customer's use needs far away.Therefore, designing more multi-configuration item novelty, operation facility, adjusting failure-free base of children safety seat lifting mechanism is necessary undoubtedly.

Summary of the invention

Technical problem to be solved in the utility model be to overcome the defect of prior art and provide a kind of simple in structure, easy to operate, regulate failure-free base of children safety seat lifting mechanism.

Technical matters of the present utility model is achieved through the following technical solutions:

A kind of base of children safety seat lifting mechanism, comprise body and the base plate that is arranged on body bottom surface, this base plate is anterior to be hinged with body bottom surface, in described body, be provided with the permanent seat that is fixed on base plate rear portion, this permanent seat trailing flank is provided with along the upper and lower distribution multiple lock teeth of permanent seat; In described body, be also provided with lifting handle, this lifting handle upper end is stretched out body and is exposed, and middle part rotates and is connected with body; Described lifting handle leading flank is provided with lock dog, and corresponding engagement is equipped respectively with described multiple lock teeth for this lock dog; Between lifting handle trailing flank and body, be provided with the Compress Spring of mutual pushing tow.

The upper end that described lifting shakes hands to expose is provided with operating groove.

Described body is to be made up of the upper cover being fastened and connected mutually and lower cover.

Compared with prior art, the utility model provides a base lifting mechanism being made up of permanent seat, lifting handle and Compress Spring etc., it is mainly engaged equipped or departs from the lock dog on lifting handle leading flank by the multiple lock teeth on permanent seat trailing flank, thereby form height locking and the lift adjustment of the relative base plate of body, structure after improvement has simplicity of design, easy to operate, regulate the advantages such as reliable.

The specific embodiment

To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.

As shown in Fig. 1～Fig. 7,1. body, 11. upper covers, 12. lower covers, 2. base plate, 3. lifting handle, 31. operating grooves, 32. lock dogs, 33. rotating shafts, 4. Compress Spring, 5. permanent seat, 51. lock teeth.

Base of children safety seat lifting mechanism, the base of children safety seat that is mainly used in making to be installed on automotive seat possesses elevating function, and then meets the angle of back-rest adjusting of child safety seat, and convenient for children is taken more comfortable.

Described base lifting mechanism is using the view left side shown in Fig. 1 as anterior, view right side is as rear portion, it comprises a body 1, this body is to be made up of the upper cover 11 being fastened and connected mutually and lower cover 12, be provided with base plate 2 in body 1 bottom surface, this base plate front portion is articulated and connected in body 1 bottom surface by bearing pin, and base plate 2 rear portions are provided with mount pad, and the identical setting-in of this mount pad enters in the mounting hole of lower cover 12 bottom surfaces.

In described body 1, be provided with permanent seat 5, the installation that fixes of this permanent seat bottom and the mount pad at base plate 2 rear portions, permanent seat 5 trailing flanks are provided with multiple along the upper and lower distribution lock tooth 51 of permanent seat; Lifting handle 3 is also installed in described body 1, these both sides, lifting handle middle part are respectively in rotating shaft 33 is rotatably installed in body 1, lifting 3 tops of shaking hands are stretched out upper cover 11 and are exposed using as operating side, and the upper end of exposing at it is also provided with the operating groove 31 that stretches into facilitate inside pressing operation for finger; Described lifting 3 leading flanks of shaking hands contact with permanent seat 5 trailing flanks, and this lifting 3 lower end leading flanks of shaking hands are provided with a lock dog 32, and lock dog just in time with multiple lock teeth 51 on permanent seat 5 leading flanks respectively corresponding engagement be equipped with; Lifting is shaken hands to be provided with Compress Spring 4 between 3 lower end trailing flanks and body 1 and is made mutual pushing tow, therefore the lifting under normality is shaken hands 3 lower ends by compression spring 4 pushing tows can drive lock dog 32 to engage to be all the time fitted in lock tooth 51.

Under normal conditions, the lock dog 32 on lifting handle 3 is because engagement is fitted in the lock tooth 51 of permanent seat 5, therefore the relative base plate 2 of body 1 cannot carry out lifting for the utility model; When inwardly pressing lifting handle 3 upper ends of exposing, this moving lifting handle 3 rotates around rotating shaft 33, the elastic force that its lower end overcomes Compress Spring 4 rotates backward, and then drive lock dog 32 and the lock tooth 51 on permanent seat 5 to depart from, now only need to promote lifting handle 3, can drive the relative base plate 2 of body 1 with lifting gradually shown in Fig. 5 ~ Fig. 7; When relative base plate 3 liftings of body 1 are to correct position, only need to discharge the pressing force of lifting handle 3, rotate forward the lower end that promotes lifting handle 3 under Compress Spring 4 effects, and then driving lock dog 32 again to engage and be equipped with and lock with the new lock tooth 51 on permanent seat 5, whole base is adjusted to proper height.
