Abstract

The utility model relates to a folding device, including handlebar rest, button, handlebar rest both sides and bottom all be equipped with the breach, breach punishment in both sides do not is equipped with first connecting hole, and is articulated with the second connecting hole that two handrail tube tip were established respectively through this first connecting hole, is equipped with the button that the spring top pushed away in the breach of bottom, handlebar rest on be equipped with two and be centrosymmetric inclination guide way and a through -hole, be equipped with two on the button and be the horizontal guide way of centrosymmetric and a vertical guide way, the button on two horizontal guide ways align one by one with two inclination guide ways on the handlebar rest to through pin joint, two handrail tube tip are equipped with hooked hand's chock, and the chock that should hook hand is connected on this pin, the button on vertical guide way align with a through -hole on the handlebar rest to pass through pin joint, the utility model discloses when the crib did not use, occupation space was little, conveniently deposited, when the crib used, simple to operate, security performance were good.

Description

A kind of folding mechanism

Technical field

The utility model belongs to the armrest joint technical field of infanette, more particularly to a kind of for handrail pass in infanette Section can fold the folding mechanism of folding.

Background technology

The infanette for being used at present is that, by bolt assembly assembled formation, when such as infanette is not used, dismounting is compared a bit It is cumbersome, and shared space is larger, when also baby is outgoing, is unfavorable for that band infanette is gone out, so arranging in infanette Folding mechanism is critically important, can make infanette when not in use, and volume-diminished takes up room little.

The content of the invention

The purpose of this utility model is to overcome the shortcomings of that prior art is present, and provides a kind of for handrail in infanette Joint can fold the folding mechanism of folding.

The purpose of this utility model is by following technical solution completing, including armrest seat, button, described handrail Seat both sides and bottom are all provided with jagged, and both sides indentation, there is respectively equipped with the first connecting hole, by first connecting hole respectively with two The second connecting hole set by root handrail tube end is hinged, button of the bottom notch built with spring push；On described armrest seat Two gradient gathering sills being centrosymmetric and a through hole are provided with, button is provided with two laterally steering grooves being centrosymmetric Groove is vertically directed with one；A pair of two gradient gathering sills 1 on two laterally steering grooves on described button and armrest seat Together, and by pin connect, two handrail tube ends are provided with hooked hand's chock, and hooked hand's chock is connected on the pin；Described One on button is vertically directed groove and aligns with a through hole on armrest seat, and is connected by pin.

Preferably, two gradient gathering sills on described armrest seat are in "eight" shape, and through hole be located at this two Center between individual gradient gathering sill.

Preferably, two laterally steering grooves on described button are in " one " font, and one is vertically directed groove and is located at Center lower section between two laterally steering grooves.

The beneficial effects of the utility model are：When infanette is not used, take up room little, convenient storage, while helping In reduction cost of transportation；It is easy for installation, have a safety feature when infanette is used.

Fig. 2 is exploded perspective structural representation of the present utility model.

Fig. 3 is main view cross-sectional view of the present utility model.

Label in accompanying drawing is respectively：1st, armrest seat；2nd, button；3rd, handrail tube；4th, spring；11st, the first connecting hole；12、 Gradient gathering sill；13rd, through hole；21st, laterally steering groove；22nd, it is vertically directed groove；31st, the second connecting hole；32nd, hook hand chock.

Specific embodiment

Detailed introduction is done to the utility model below in conjunction with accompanying drawing：As shown in accompanying drawing 1 to 3, the utility model includes Armrest seat 1, button 2, the described both sides of armrest seat 1 and bottom are all provided with jagged, and both sides indentation, there is respectively equipped with the first connecting hole 11, it is hinged with the second connecting hole 31 set by two ends of handrail tube 3 respectively by first connecting hole 11, bottom notch is built-in There is the button 2 of the pushing tow of spring 4；Described armrest seat 1 is provided with two gradient gathering sills 12 being centrosymmetric and a through hole 13, button 2 is provided with two laterally steering grooves 21 being centrosymmetric and one is vertically directed groove 22；On described button 2 Two laterally steering grooves 21 align one by one with two gradient gathering sills 12 on armrest seat 1, and are connected by pin, two handrails The end of pipe 3 is provided with hooked hand's chock 32, and hooked hand's chock 32 is connected on the pin；One on described button 2 is vertically directed Groove 22 aligns with a through hole 13 on armrest seat 1, and is connected by pin.

Two gradient gathering sills 12 on described armrest seat 1 are in "eight" shape, and a through hole 13 is located at this two tiltedly Center between degree gathering sill 12.

Two laterally steering grooves 21 on described button 2 be in " one " font, and one be vertically directed groove 22 positioned at this two Center lower section between individual laterally steering groove 21.

Using method of the present utility model is：When infanette is used, as long as button 2 is down pressed, spring is in compression State, while two handrail tubes 3 are pulled back being opened flat shape；When infanette draws in, as long as two handrail tubes 3 are pulled back vertically Shape, spring is in without compressive state.In the motion process, on the two laterally steering grooves 21 and armrest seat 1 on button 2 Two gradient gathering sills 12 in pin also move therewith.

The utility model is not limited to above-mentioned embodiment, all no matter constitute making any change in its shape or material It, using structure design provided by the utility model, is all a kind of deformation of the present utility model to be, is considered as new in this practicality Within type protection domain.
