After adopting the structure, the foldable locking device overcomes shortcomings of complicated existing structure and unreliable locking, and has the advantages that the device is simple and reasonable in structure, convenient in operation, reliable in use, low in cost and the like.
Description
Technical field
The utility model relates to a kind of folding device, the folding device that can lock during particularly a kind of folding.
Background technology
Folding device is the very general connector of a kind of use, mainly plays hinge effect, and when using some special occasions, folding device need lock when softened state or folded state, guarantees to strut or folding safe and reliable.Folding ironing board as present use just needs folding locking device, this structure is by the hinge left and right sides connector that is hinged, fix a telescopic flexible lock pin on the connector therein, the corresponding lockhole that cooperates with flexible lock pin that is provided with on another connector is by flexible lock pin and cooperating of lockhole realizing strutting of folding ironing board or folding locking.But this structure in use has the following disadvantages: the one, left and right sides connector by hinge hinged after, also need the lockhole on the connector of the left and right sides, flexible lock pin being installed and being complementary in addition, structure more complicated, processing and production cost obviously increase; The 2nd, adopt some locking of this structure, keyed end is stressed big, easily causes left and right sides connector distortion; The 3rd, quality of fit requirement height, fit clearance is excessive will to cause two folding ironing board out-of-flatnesses.For this reason, many manufacturers and knowledgeable people develop specially and develop, but do not have comparatively ideal product to emerge so far as yet.
Summary of the invention
In order to overcome the above-mentioned disadvantage that existing folding locking device exists, the purpose of this utility model provide a kind of simple and reasonable, easy to operate, use the folding locking device reliable, that production cost is low.
The technical scheme that its technical problem that solves the utility model adopts, it comprises left and right sides connector, hinge, left and right sides connector is respectively equipped with hinge hole and is hinged by hinge, the hinge hole of described left and right sides connector is provided with locating groove, described hinge is provided with double-screw bolt, reference column and guide pillar successively, reference column be provided with hinge hole on the positioning key that is complementary of locating groove, the guide pillar of hinge cooperates with hinge hole, the double-screw bolt side of hinge is fixed with nut, and the guide pillar side of hinge is provided with back-moving spring.
Left and right sides connector installs and fixes for convenience, is respectively equipped with fixing hole on the connector of the described left and right sides.
After adopting said structure, following advantage and effect are compared with prior art arranged: in the time of on using folding ironing board, left and right sides connector correspondence is fixed on two folding ironing boards, cooperate with locating groove on the connector of the left and right sides by the positioning key on the hinge and to realize strutting or folding locking of folding ironing board, simple in structure, easy to use, cost is low.

Fig. 3 is the structural representation of the utility model left side connector.
Fig. 4 is the structural representation of the utility model hinge.
The specific embodiment
Fig. 1 is to shown in Figure 4, specific embodiments for the folding locking device of the utility model, it comprises left and right sides connector 1,2, hinge 3, left and right sides connector 1,2 are respectively equipped with hinge hole 7 and are hinged by hinge 3, left and right sides connector 1, be respectively equipped with fixing hole 6 on 2, described left and right sides connector 1,2 hinge hole 7 is provided with symmetrical locating groove 8, described hinge 3 is provided with double-screw bolt 9 successively, reference column 10 and guide pillar 12, reference column 10 be provided with hinge hole 7 on the positioning key 11 that is complementary of locating groove 8, the guide pillar 12 of hinge 3 cooperates with hinge hole 7, double-screw bolt 9 sides of hinge 3 are fixed with nut 4, and guide pillar 12 sides of hinge 3 are provided with back-moving spring 5.
When left and right sides connector 1,2 when softened state folds, press hinge 3, hinge 3 moves inward after overcoming the elastic force of back-moving spring 4, make positioning key 11 and left and right sides connector 1 on hinge 3 reference columns 10, locating groove 8 on 2 the hinge hole 7 separates, rotate left and right sides connector 1 then, 2, unclamp hinge 3, when left and right sides connector 1, when 2 mutual rotations 180 are spent, left and right sides connector 1, the positioning key 11 that locating groove 8 on 2 the hinge hole 7 overlaps again on the reference column 10 with hinge 3 is corresponding, elastic force effect down hinge 3 at back-moving spring 4 automatically resets, positioning key 11 on the reference column 10 inserts left and right sides connector 1 again, in the locating groove 8 on 2 the hinge hole 7, thereby finish left and right sides connector 1,2 folding mutually and locking.When left and right sides connector 1,2 when folded state struts, its operation principle and roughly the same above-mentioned no longer repeats at this.
Claims (2)
1. folding locking device, comprise left and right sides connector (1,2), hinge (3), left and right sides connector (1,2) being respectively equipped with hinge hole (7) also is hinged by hinge (3), it is characterized in that: described left and right sides connector (1,2) hinge hole (7) is provided with locating groove (8), described hinge (3) is provided with double-screw bolt (9) successively, reference column (10) and guide pillar (12), reference column (10) be provided with hinge hole (7) on the positioning key (11) that is complementary of locating groove (8), the guide pillar (12) of hinge (3) cooperates with hinge hole (7), double-screw bolt (9) side of hinge (3) is fixed with nut (4), and guide pillar (12) side of hinge (3) is provided with back-moving spring (5).
