Description

A kind of safe draw ring device that is used to amount to furniture

Affiliated technical field

The utility model has related to a kind of safety device, particularly relates to a kind of safe draw ring device that is used to amount to furniture.

Background technology

Amounting to furniture is that a kind of skeleton can the rotation be amounted to the furniture of using reduced volume, is convenient to collection after its benefit is to amount to, when using, launch, and be a convenient design of living.Yet just because amounting to furniture can rotate and amount to, if careless, contingency such as may take place to fall accidentally because the unbalance stress burst is amounted to or crush during use.So it is just crucial especially to amount to safe, the stability of furniture requirement, especially the normal children uses amounts to furniture, and it is thorough more to need to consider.The existing furniture of amounting to lacks the anti-pinch safety device, and its safety, firm mechanism is not enough, and such furniture (when particularly children use) in use of amounting to has serious security hidden trouble.

Summary of the invention

For overcoming above-mentioned shortcoming, the utility model provides a kind of safe draw ring device that is used to amount to furniture, and it can make the good and safe anti-pinch of the firm performance of amounting to furniture, can allow the user particularly children guarantee safety in use.

The purpose of this utility model is achieved in that the utility model is installed in and amounts on the furniture, comprises active unit and limiting unit; Active unit comprises two angle bar tie rods and two tie rods, but angle bar tie rod and tie rod connect to two active units in pivot pendulum mode respectively, but two active units connect preceding foot rest and the rear leg of amounting to the furniture left and right sides in pivot pendulum mode respectively, but and be fixed in pivot pendulum mode and amount on the furniture cushion frame left and right sides, make whole the fold-down seat can rotary moveable; Limiting unit comprises attaching parts, safety cock, spring and draw ring, the furniture rotary moveable is amounted in restriction, safety cock is installed on the attaching parts, the safety cock head has an inclined-plane, during installation the inclined-plane down, the safety cock head slightly is wider than afterbody, spring entangles the safety cock afterbody, be stuck at the safety cock head, the safety cock tail end has an aperture, and draw ring is installed on this aperture; Wherein on the angle bar tie rod of a side safety vent is arranged, one limiting holes that can supply safety cock to eject is arranged on the tie rod of homonymy, limiting unit is fixed on the angle bar tie rod of safety vent by attaching parts, limit the mobility of active unit when the safety cock of limiting unit ejects from the limiting holes on the tie rod of active unit, thereby limited the rotary moveable of fold-down seat.

Above-mentioned attaching parts afterbody has a locating hole, and this locating hole aligns with safety vent on the angle bar tie rod, passes for safety cock.

Above-mentioned two angle bar tie rods and two tie rods are each a slice of left-right symmetry, but being fixed in pivot pendulum mode respectively, amount on the furniture cushion frame left and right sides by two angle bar tie rods, but and be connected with the preceding foot rest of the left and right sides in pivot pendulum mode respectively, but two tie rods connect the angle bar tie rod and the rear leg of the left and right sides respectively in pivot pendulum mode, make the ability that family has had whole rotary moveable of amounting to.

The beneficial effects of the utility model are, in use, can only pull back draw ring makes safety cock break away from the tie rod safety vent, can recover the rotation of fold-down seat and amount to ability, thereby can avoid the user to amount to furniture cushion frame, preceding foot rest, rear leg burst rotation and amount to because of force distribution inequality or improper use cause in use, the accident that meets accident is guaranteed safe in utilization.The utility model can be widely used in various amounting in the furniture such as fold-down seat, foldable table, and is simple in structure, easy to operate, meets people's demand, has good market prospects.

The specific embodiment

Shown in Fig. 1-3: being applied in the fold-down seat with the utility model is example, and the utility model comprises amounts to active unit and limiting unit; Active unit comprises two angle bar tie rods 4 and two tie rods 5, but angle bar tie rod 4 connects into two active units in pivot pendulum mode respectively with tie rod 5, two angle bar tie rods 4 and two tie rods 5 are each a slice of left-right symmetry, but two angle bar tie rods 4 are fixed on cushion frame 2 left and right sides of fold-down seat in pivot pendulum mode respectively, but and be connected with the preceding foot rest 1 of the left and right sides in pivot pendulum mode respectively, but two tie rods 5 connect the angle bar tie rod 4 and rear leg 3 of the left and right sides respectively in pivot pendulum mode, make whole fold-down seat energy rotary moveable; Wherein on the angle bar tie rod 4 of a side safety vent 41 is arranged, a limiting holes 51 is arranged on the tie rod 5 of homonymy; Limiting unit comprises attaching parts 6, safety cock 7, spring 8 and draw ring 9, restriction fold-down seat rotary moveable, attaching parts 6 afterbodys have a locating hole 61, this locating hole 61 aligns with safety vent 41 on the angle bar tie rod 4, pass for safety cock 7, attaching parts are fixed on the angle bar tie rod 4 of safety vent 41; Safety cock 7 heads have an inclined-plane, the inclined-plane down during installation, safety cock 7 heads slightly are wider than afterbody, spring 8 entangles safety cock 7 afterbodys, is stuck at safety cock 7 heads, makes safety cock 7 have the ejection ability, and the stroke distances that is pulled of restriction safety cock 7, safety cock 7 tail end have an aperture, and draw ring is installed on this aperture, can pull back safety cock and limit the locating hole that the safety cock afterbody leaves the attaching parts afterbody; When fold-down seat was opened, the safety cock 7 of limiting unit ejected from the limiting holes 51 on the tie rod 5 of active unit and has limited the mobility of active unit, thereby has limited the rotary moveable of fold-down seat.

Shown in Fig. 4-5: the utility model is installed on the fold-down seat, when the fold-down seat Unscrew, its active force drives cushion frame 2 rotations and puts down, when the safety cock 7 of limiting unit touches the tie rod 5 of active unit, because safety cock 7 head inclinations face down when mounted, under the effect of inclined plane, safety cock 7 reclaims automatically, its tie rod 5 is passed through smoothly, amount to chair and can continue rotary expansion; When fold-down seat rotates to range, when fold-down seat is opened fully, fold-down seat rear leg 3 withstands cushion frame 2, limit fold-down seat and continued rotary expansion, in this simultaneously, safety cock 7 ejects from tie rod 5 limiting holes 51 under spring 8 effects that match, since above safety cock 7 heads than following face length, limited safety cock 7 and from tie rod 5 safety vents 51, broken away from, limited the rotation of fold-down seat and amounted to ability, thereby made the firm more one of fold-down seat, the user is when taking use, its human body is to the gravity of fold-down seat, pressure can better on average disperse, and unlikelyly amounts to because of the burst of the unequal generation fold-down seat of force distribution easily, causes contingency.Only pull back draw ring 9, the safety cock 7 of limiting unit is pulled leaves tie rod 5 safety vents 51, fold-down seat can recover rotation and amount to ability, makes the fold-down seat can folding for storing.

The utility model can be widely used in various amounting in the furniture such as fold-down seat, foldable table.
