Abstract

The utility model discloses a folding mechanism, including mechanism's body, lock body, folding lock and locomotive pivot, be provided with the lock body on mechanism's body, be provided with folding lock on the lock body, be provided with the locomotive pivot on the lock body, the locomotive pivot is through folding lock and lock body fixed connection. The utility model discloses a beneficial effect be the aluminum alloy through the material that sets up lock body, folding lock and locomotive pivot for this folding mechanism weight alleviates greatly, and the while is portable also, through the recess that is provided with the recess that suits with folding lock shape and size and suits with locomotive pivot shape and size on the lock body and the folding lock good with lock body meshing degree for this folding mechanism simple structure and compactness, the convenient and fast thereby the operation is got up has also reduced manufacturing cost to a certain extent.

Description

A kind of fold mechanism

Technical field

The utility model belongs to technical field, and in particular to a kind of fold mechanism.

Background technology

Foldable structure can be divided into two big class according to its kinetic characteristic showed during expansion：One class is each several part fortune Move as rigid motion, be called multi-rigid body system, its sports immunology and internal force analysis is easier to solve；It is another kind of, it is portion While part experiencings in space big rigid motion, also there is the amoeboid movement of itself, show rigid motion with deformation Motion interacts, the feature of strong coupling.Self-stabilization member structure just belongs to latter type, wherein the design for locking hinge is whole The basis of individual self-stabilization folded structure design, directly affects the reasonability and ease of use of structure.Preferably condition of self-locking is During folded exhibition, internal force is produced in the rod member of composition lock hinge, internal force change shows in the slow trend for rising steep drop, rate of change The feature of the slow variable of wide variation and fast variable by a small margin.This kinetic characteristic must be retouched using nonlinear theory State, the difficult point of this exactly this Structure Calculation is located.Various fold mechanisms are had existed in prior art.

However, current fold mechanism weight it is larger it is not readily portable, operation is comparatively laborious and production cost is higher.

Therefore, invent a kind of fold mechanism and seem very necessary.

Utility model content

The purpose of this utility model is to provide a kind of fold mechanism, to solve above-mentioned background technology in propose current folding Folded mechanism's weight it is larger it is not readily portable, operate the higher problem of comparatively laborious and production cost.

For achieving the above object, the utility model provides following technical scheme：A kind of fold mechanism, including mechanism body, Lock body, fold latch and headstock rotating shaft, in the mechanism body lock body is provided with；Fold latch is provided with the lock body；On lock body It is provided with headstock rotating shaft；The headstock rotating shaft is fixedly connected by fold latch with lock body.

Preferably, the lock body, fold latch and headstock rotating shaft adopts aluminum alloy materials, aluminium alloy to adopt progressive forming method Processing technology.

Preferably, the groove being adapted with fold latch form and dimension, the fold latch and lock are provided with the lock body Body is conveniently detachably connected with.

Preferably, the groove adaptable with headstock configured rotation shaft and size, the headstock rotating shaft are provided with the lock body One end be conveniently detachably connected with lock body.

Preferably, the fold latch is ground high to reach degree of engagement between the two with lock body by mating engagement.

Technique effect of the present utility model and advantage：The fold mechanism, by arranging lock body, fold latch and headstock rotating shaft Material is aluminium alloy so that the fold mechanism weight mitigates significantly, while also allowing for carrying；By be provided with lock body with The adaptable groove of fold latch form and dimension and the groove adaptable with headstock configured rotation shaft and size and engage with lock body The fold latch spent so that the fold mechanism simple and compact structure, it is convenient and swift so as to operate, also to a certain extent Reduce production cost.

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 fold mechanism as shown in Figures 1 to 4, including mechanism body 1, lock body 2, folding Lock 3 and headstock rotating shaft 4, are provided with lock body 2 in the mechanism body 1；Fold latch 3 is provided with the lock body 2；Set on lock body 2 It is equipped with headstock rotating shaft 4；The headstock rotating shaft 4 is fixedly connected by fold latch 3 with lock body 2.

Further, the lock body 2, fold latch 3 and headstock rotating shaft 4 adopt aluminum alloy materials, aluminium alloy using continuously into Shape method processing technology so that the fold mechanism weight mitigates significantly, while also allowing for carrying.

Further, be provided with the lock body 2 with the form and dimension of fold latch 3 be adapted groove, the fold latch 3 with Lock body 2 is conveniently detachably connected with so that the fold mechanism simple and compact structure.

Further, the groove being adapted with the form and dimension of headstock rotating shaft 4 is provided with the lock body 2, the headstock turns One end of axle 4 is conveniently detachably connected with lock body 2 so that the fold mechanism simple and compact structure and convenient to operation.

Further, the fold latch 3 is ground high to reach degree of engagement between the two with lock body 2 by mating engagement so that The fold mechanism simple and compact structure, so as to reduce production cost.

Operation principle：The fold mechanism, by arranging the material of lock body 2, fold latch 3 and headstock rotating shaft 4 aluminium alloy is, So that the fold mechanism weight mitigates significantly, while also allowing for carrying；By be provided with lock body 2 with the shape of fold latch 3 and The adaptable groove of size and the groove being adapted with the form and dimension of headstock rotating shaft 4 and the folding good with the degree of engagement of lock body 2 Lock 3 so that the fold mechanism simple and compact structure, it is convenient and swift so as to operate, life is also reduced to a certain extent Produce cost.

Using technical scheme described in the utility model, or those skilled in the art's opening in technical solutions of the utility model Give, design similar technical scheme, and reach above-mentioned technique effect, fall into protection domain of the present utility model.
