The specific embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figures 1 to 4, but a kind of Folding device 100 with latch-up structure 3 that the utility model relates to comprises two carriages 1 and two folded rods 2, and these two carriages 1 are parallel to each other; These two folded rods 2 are then between this two carriage 1 and cross-shaped, these two folded rods 2 articulate at the place, crosspoint, and this two folded rod 2 articulates with one of this two carriage 1 respectively at same end, in the embodiment that utility model provides, this two folded rod 2 all articulates at one of lower end and this two carriage 1.Above-mentioned all identical with the statement in the background technology, thus no longer its structure is described further, below mid point improvement of the present utility model is described:
Be formed with latch-up structure 3 between the carriage 1 that at least one folded rod 2 is relative with it in this two folded rod 2, promptly this latch-up structure 3 can only be formed among Fig. 1 and Fig. 4 between the left side carriage 1 and folded rod 2, also can only be formed among Fig. 1 and Fig. 4 between the right carriage 1 and the folded rod 2, but certainly also both sides all be formed with latch-up structure 3.Below this latch-up structure 3 is described in detail:
This latch-up structure 3 comprises:
Connecting rod 31, its two ends are articulated in respectively on folded rod 2 and the carriage 1, and are formed with resistance piece 311 and limited block 312, and this resistance piece 311 is used to replace this following S shape fastener 32 and limits it and rotate 312 elastic displacements that are used to limit elastic component 34 of this limited block;
S shape fastener 32, its middle part is articulated on the connecting rod 31, and two ends form first draw-in groove 321 and second draw-in groove 322 respectively;
As this elastic component 34, resist a kind of specific embodiment that is connected between piece 311 and this S shape fastener 32, even this elastic component 34 orders about this S shape fastener 32 and is resisted against a kind of embodiment that resists on the piece 311, the pivoting point of this S shape fastener 32 and this connecting rod 31 resists between piece 311 and the limited block 312 at this, this resistance piece 311 stops that this S shape fastener 32 clockwise rotates, and this elastic component 34 is stage clip and is connected the end that S shape fastener 32 has second draw-in groove 322, it drives this S shape fastener 32 and clockwise rotates, and this S shape fastener 32 of 35 drivings of this actuator this moment rotates counterclockwise.Certainly in order to realize this purpose---this elastic component 34 orders about this S shape fastener 32 and is resisted against on the resistance piece 311, also has a lot of alternative, be extension spring such as this elastic component 34, but it is connected the end that S shape fastener 32 has first draw-in groove 321; Or the pivoting point of this S shape fastener 32 and this connector is not positioned between this resistance piece 311 and the agretope piece, as long as can realize above-mentioned purpose, will not set forth one by one at this.
In order to make this S shape fastener 32 can have preferable resistancing action with this resistance piece 311, this S shape fastener 32 also protrudes out and forms projection 323, and this projection 323 can lean and limit this S shape fastener 32 and rotate with resistance piece 311.
Be articulated on this carriage 1 for the ease of this connecting rod 31, also form the mount pad 11 that articulates for connecting rod 31 on this carriage 1.
As a kind of embodiment of this actuator 35, this actuator 35 is a rope 351, and pulling for the convenience of the users, and these rope 351 ends also comprise draw ring 352.Certainly this actuator 35 also can adopt the form of automation, and such as driven by motor etc., its mode is more, as long as can realize driving this this resistance piece 311 of S shape fastener 32 disengagings, so do not enumerate one by one.
Below the duty of the present utility model and the course of work are described in detail:
As depicted in figs. 1 and 2, be in the schematic diagram of full open position for the utility model shown in it; Wherein, this first draw-in groove 321 and the engaging of first fixture block 331, this moment can be for normally use so this open mode is in a stable status because this elastic component 34 is resisted against this S shape fastener 32 resists on the piece 311 and can't rotate.
When but needs carry out folding to this Folding device 100, open or spur actuator 35 and make this S shape fastener 32 towards the direction motion that breaks away from this resistance piece 311, being about to this first draw-in groove 321 separates with this first fixture block 331, when first draw-in groove 321 with after first fixture block 331 really separates, can close or unclamp this actuator 35, this moment since this S shape fastener 32 still by the elastic force effect of elastic component 34, so this S shape fastener 32 will return to the state that is resisted piece 311 resistances.But be somebody's turn to do Folding device 100 continuation foldings and work as, and when reaching end-state, as shown in Figure 3 and Figure 4, this second fixture block 332 can fall into this second draw-in groove 322, this moment is also because this elastic component 34 is resisted against this S shape fastener 32 resists on the piece 311 and can't rotate, so this final closed state also is a stable status and can be for normally use.
When but needs are opened this Folding device 100, open or spur this actuator 35 and make this S shape fastener 32 towards the direction motion that breaks away from this resistance piece 311, being about to this second draw-in groove 322 separates with this second fixture block 332, when second draw-in groove 322 with after second fixture block 332 really separates, can close or unclamp this actuator 35, this moment since this S shape fastener 32 still by the elastic force effect of elastic component 34, so this S shape fastener 32 will return to the state that is resisted piece 311 resistances.But and when should Folding device 100 continuing to open, and when reaching end-state, as depicted in figs. 1 and 2, this first fixture block 331 can fall into this first draw-in groove 321, thereby has got back to the state of opening fully.
The utility model is owing to be formed with latch-up structure 3 between folded rod 2 carriage 1 relative with it, and this locking mechanism stays open the stable of state by the engaging of first draw-in groove 321 and first fixture block 331, and the engaging by second draw-in groove 322 and second fixture block 332 keeps the stable of folding state again; Simultaneously when needs change folding state, also can drive and can realize by this actuator 35 simply, thus the utlity model has simple in structure, cost low and characteristics such as processing ease.
The foregoing description and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
