Description

Position limited folding device

Technical field

The utility model relates to a kind of folder, especially relates to the position limited folding device in the household goods such as fold-away mattress, tatami.

Background technique

The household goods such as mattress, folding chair will can take larger space when transporting usually according to original shape, bring very large trouble to transport.Then need to use angle-modulator to connect according to folding mode.Existing angle-modulator is placed in usually the joint part of mattress, folding chair, sofa etc., can regulate when needed, the scope of adjustment is reversible and easily loosens.If above-mentioned article are folded into suitable size transport, need to increase multiple regulator, but in use, but require that regulator can reach position-limiting action, avoid article to produce angle change when not needing to regulate, and existing angle-modulator cannot meet this function.

Model utility content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can either conveniently fold the position limited folding device that in use can limit again folding position.

To achieve the above object of the invention, provide a kind of position limited folding device, comprise the first bearing and the second bearing, described first bearing is extended with outer hinge plate, the second described bearing is extended with inner hinge plate, described outer hinge plate and inner hinge plate hinged; Also comprise latch and lock pin, described lock pin inserts in the lockhole of latch, and latch is connected by lock pin with outer articulated slab; Described latch has latch ratchet, described interior articulated slab has articulated slab ratchet, described latch ratchet can be engaged with articulated slab ratchet; Described lock pin has spring, and described spring one end is resisted against outer articulated slab, and the other end is connected on latch.

First bearing and the second bearing are generally tubulose, for connecting the skeleton part of mattress, bed board, folding chair, and on bearing, extend articulated slab connect, the outer articulated slab of the first bearing is hinged on the inner side of the interior articulated slab of the second bearing, connected by pivot, the first bearing can and the second bearing between have the relative movement of rotation.Latch is the structure with ratchet, corresponding with the ratchet of articulated slab in the second bearing, ratchet occlusion under normal conditions, and is locked by the spring on lock pin, and the first bearing and the second bearing are locked relative position and can not rotate.First bearing has pin-and-hole, lock pin is connected on the outer articulated slab of the first bearing through the lockhole of latch, when lock pin rotates, the ratchet on the ratchet of latch and interior articulated slab departs from, and does not now have restriction to rotate between the first bearing and the second bearing.Spring to latch locking power, makes latch not easily depart from ratchet when lockup state under the state of not stressing.

Described lock pin is prismatic, described lockhole is prismatic hole.

Preferably, described lock pin cross section is regular hexagon, described latch has regular hexagon hole, and described lock pin is connected in latch.

Outer articulated slab and interior articulated slab can be individual layers, and when outer articulated slab and interior articulated slab are individual layers, lock pin is install fastening nut on lock pin through being connected on outer articulated slab by latch after latch.Preferably, described first bearing has the outer articulated slab that two pieces parallel, described second bearing has the interior articulated slab that two pieces parallel, it is inner that interior articulated slab is articulated with outer articulated slab.

Preferably, described outer articulated slab and interior articulated slab are circle, and the first described bearing is positioned at outer articulated slab top, and the second described bearing is positioned at articulated slab top.Interior articulated slab and outer articulated slab can rotate, but owing to being positioned at top, therefore have spacing, make to produce a spacing relation between the first bearing and the second bearing, can not rotate over 180 °.

Preferably, the first described bearing is concordant with the second top.Described top refers to the part that circular articulated slab the top is connected with bearing.

Preferably, described lock pin is L shape.

Position limited folding device of the present utility model, it is hinged that first bearing and the second bearing pass through articulated slab, make can bend between the first bearing and the second bearing, turn increasing locking block is undertaken spacing to articulated slab in the second bearing by ratchet, when needs transport, by rotating lock pin, the ratchet of locking block and interior articulated slab is departed from, lift restrictions and the first bearing and the second bearing can be rotated, household goods are folded, when normally using, when first bearing and the second bearing arrive home position, the elastic force stinging again merga pass spring in the ratchet of locking block and interior articulated slab makes the ratchet of locking block tightly be fastened in the ratchet of interior articulated slab, make to reach spacing effect between the first bearing and the second bearing.

The beneficial effects of the utility model are, facilitate the transport of large-scale articles for use, and article can be folded, and can not produce folding effect have good position-limiting action in normal using process.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described further.

A kind of position limited folding device according to Fig. 1, Fig. 2 and Fig. 3, comprises the first bearing 1 and the second bearing 2, and the first described bearing 1 and the second bearing 2 entirety are tubulose, and the bearing of tubulose is mainly used in the holder part connecting the articles for use such as mattress, folding chair.First bearing 1 extends and two parallel outer articulated slab 11, second bearings 2 extends two parallel interior articulated slabs 21, outer articulated slab 11 has pivot hole 12, interior articulated slab 21 has interior pivot hole 22, both are hinged by pivot 6.Interior articulated slab 21 is placed in that outer articulated slab 11 is inner, and interior articulated slab 21 and outer articulated slab 11 are plectane, and the first bearing 1 is positioned at outer articulated slab 11 top, and the second bearing 2 is positioned at articulated slab 21 top, and both can rotary motion, but can be limited on top.Described interior articulated slab 21 there is an articulated slab ratchet 23.Also comprise latch 3, described latch 3 also has a latch ratchet 31, the ratchet 31 of latch 3 is mutually corresponding with the ratchet 23 of interior articulated slab 21, and can mutually be engaged.Outer articulated slab 11 has pin-and-hole 13, described latch 3 has lockhole, lock pin 4 cross section of L shape is hexagon, cooperatively interacts with the lockhole on latch 3, and lock pin 4 is connected to each other through the pin-and-hole of outer articulated slab 11 and the lockhole of latch 3.There is ladder latch 3 side, winding spring 5 on lock pin 4, and one end of spring 5 is pressed on outer articulated slab 11, and the other end is connected on the ladder of latch 3.

Below the preferred embodiment that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent distortion or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent variations or replacement are all included in the application's claim limited range.
