Description of the drawings
The utility model is described further with reference to the accompanying drawings and examples；
Fig. 1 is the assembling schematic diagram of the utility model embodiment fold mechanism；
Fig. 2 is the structural schematic diagram of the second outline border of the utility model embodiment.
Specific implementation mode
The technique effect of the design of the utility model, concrete structure and generation is carried out below with reference to embodiment and attached drawing
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
The other embodiment that art personnel are obtained without creative efforts belongs to the model of the utility model protection
It encloses.
Referring to figs. 1 to Fig. 2, a kind of fold mechanism for frame curtain of the utility model embodiment, including be in opposite arrangement
The first outline border 1 and the second outline border 2, between the first outline border 1 and the second outline border 2 it is opposite end be respectively equipped with 3 He of the first inserted link
Second inserted link 4, it is hinged in end that the first inserted link 3 is fixed on the right end of the first outline border 1, the first inserted link 3 and the second inserted link 4, the
The end face that two outline borders 2 are held in opposite directions is recessed an accommodating chamber 21, is respectively equipped in the cavity wall of accommodating chamber 21 in an axial direction
A positioning hole 22 and second location hole 23, wherein first positioning hole 22 is located at the right side of second location hole 23.
Second inserted link 4 is inserted into accommodating chamber 21, and the first inserted link 3 and the second inserted link 4 are the equal optical axis of diameter, accommodating chamber
Room 21 is the vestibule that intracavity diameter is more than optical axis.The diameter of optical axis is slightly less than the inner diameter size of vestibule so that optical axis is inserted into accommodating
When chamber, gap very little will not shake substantially.Second inserted link 4, which is equipped with, is embedded in the positioning of first positioning hole 22 or second
The Elastic buckle 5 in hole 23, when Elastic buckle 5 is embedded in first positioning hole 22, the articulated section of the first inserted link 3 and the second inserted link 4
Inside accommodating chamber 21, when Elastic buckle 5 is embedded in second location hole 23, the first inserted link 3 is hinged with the second inserted link 4
Portion is located at outside accommodating chamber 21.
When needing to support frame curtain, Elastic buckle 5 is embedded in first positioning hole 22 so that the first inserted link 3 and
The hinge point of two inserted links 4 is inside accommodating chamber 21, on the one hand under the position-limiting action of the second outline border 2, the first inserted link 3 and
Two inserted links 4 will not relatively rotate, and the first outline border 1 and the second outline border 2 form an entirety to realize the support of frame curtain, separately
On the one hand the second outline border 2 conceals the hinge portion of the first inserted link 3 and the second inserted link 4 well, it appears that more beautiful；Together
When, it is sleeved on the first inserted link 3 by the second outline border 2 and realizes fixation, rigidity is good, and intensity is high.When needing to store frame curtain, press
Elastic buckle 5, pulls the second inserted link 4 so that Elastic buckle 5 is embedded in second location hole 23, the first inserted link 3 and the second inserted link 4
Hinge point rotates the first outline border 1 and the second outline border 2 outside accommodating chamber 21, realizes and folds.Supporting rod is reduced after folding
Overall dimensions, convenient for storage and transport.
Preferably, be equipped with pull rod 6 between the first inserted link 3 and the second inserted link 4, the both ends of pull rod 6 respectively with the first inserted link 3
