Abstract

The utility model provides an open-close apparatus for folding combined bench. The utility model is characterized in that the utility model is composed of a fixing and folding combined bench, an elastic bilateral inner lock buckle on one carrying handle, and a nail-shaped lock tongue which can move up and down and be arranged on the other carrying handle. When use, a lock-shaped lock tongue is easy to insert the elastic bilateral inner lock buckle to lock the box body under the function of the external force. The nail-shaped lock tongue slide upwards, and then the nail-shaped lock tongue can disengage from the elastic bilateral internal lock buckle, and therefore, the opening action can be completed. Compared with the open-close apparatus of the existing I-shaped lock bolt, the utility model has the advantages of convenient and fast opening and simple structure.

Description

Open-close apparatus for folding combined bench

The utility model belongs to headstock gear, particularly a kind of headstock gear of collapsible compound table stool.

Collapsible compound table stool is to have four stools and a platform after a kind of the opening, and has become the portable campaign furniture of a suitcase after folding again.The headstock gear of this compound table stool is arranged at portable last usually, its architectural feature is portable last rotating I-shaped lock bolt and the portable slotted hole that the corresponding section is offered of another side by being arranged on one of them, make both sides portable involutory, the I shape lock bolt that passes slotted hole is turned an angle, the I shape lock bolt just is locked together in two portable handles together again.When opening, the I shape lock bolt is gone to and the slotted hole correspondence position, two portable just throwing off.Through using the back to find that this headstock gear has following weak point, the I shape lock bolt must go to exactly with the slotted hole anastomosis and could open and close during folding, slightly partially a bit all is difficult to folding, often makes troubles to the user.

The purpose of this utility model is to overcome the deficiency of technology, provides another kind of simple in structure, and the collapsible combination stool headstock gear of folding with convenience newly designs.

Above-mentioned task be realize by this way as figure: this headstock gear is made up of bilateral inner lock buckle of elasticity (7) on the portable handle of the one that is fixed in collapsible compound table stool (1) and the nail shape dead bolt (5) that is loaded on another portable handle (2) correspondence position, the groove (8) that nail shape dead bolt (5) is provided with its both sides is installed on the portable handle (2) with cooperating in square lock frame (3) activity of offering on the portable handle (2), can slide up and down, on the outer panel (6) of nail shape tongue (5), be provided with plush copper outside (4).

The utility model is work like this: when people exert oneself portable an involutory time-out (mould assembling) with two, because the bilateral inner lock buckle of elasticity (7) has elasticity, nail shape dead bolt (5) is easy to insert the bilateral snap close of elasticity (7) the portable handle in both sides (2,1) is locked together in together under the power effect, when unpacking, as long as put forward outer plush copper (4) with finger, nail shape dead bolt (5) is up moved, break away from the bilateral inner lock buckle of elasticity (7) just can with two portable release, open whole collapsible compound table stool.This shows that the utility model can overcome the defective of prior art, and have easy to use, the quick and advantage of simple structure of folding.

Fig. 1 is a cutaway view of the present utility model.

Fig. 2 is along the cutaway view of A-A line among Fig. 2.

Bilateral inner lock buckle of elasticity of the present utility model (7) and nail shape dead bolt (5) have selected for use certain flexible plastics to make, the front end of (7) two elasticity buttons of the bilateral inner lock buckle of elasticity is interior to half of arrow-shaped, the head of nail shape dead bolt (5) is taper, semicircle is so that nail shape dead bolt (5) inserts in the bilateral inner lock buckle of elasticity (7).

The utility model designs for collapsible compound table stool, also can be used for similar casing and does the headstock gear use.
