The utility model comprises a box cover, a box bottom, box cores, a connecting structure for a box cover and a box bottom, and a sliding lock piece. The utility model is characterized in that a position on the inner side of the surrounding edge of the box cover and a position on the inner side of the surrounding edge of the box bottom, which are symmetrical, are provided with concave slots through which the box cores are connected; protruded convex ribs in the shape of an inverse hook are arranged on the upper edge of each concave slot; the box cores, the box cover, and the box bottom are separated, and the box cores are provided with convex slot edges corresponding to the connecting concave slot of the box cover and the connecting concave slot of the box bottom; the upper edges of slot edges are provided with corresponding concave ribs which are corresponding to the protruded convex ribs in the shape of an inverse hook on the box bottom and on the box cover; the box cores, the box cover, and the box bottom are connected in close fit according to a convex concave slot and a convex concave rib. The utility model has the advantages that the trouble that the box cores need replacing is solved, the structure of a box lock is simplified by means of the principle of dynamics, and production cost is reduced.

Description

Be convenient to change the hardware ﹠ tools box of box core

The utility model belongs to a kind of packing box, particularly a kind of hardware ﹠ tools box of being convenient to change the box core.

At present, domestic hardware ﹠ tools box is generally injection molded by plastic material, have characteristics aesthetic in appearance, easy to carry, practical, but the existing general box core of box type is fixed, be disposable injection molded by the mould corresponding with outer box, when existing box core was inapplicable, the box core that more renews just needed the integral replacing instrument cases, change the mould of original instrument cases, can make troubles and waste to the user thus.

The purpose of this utility model is to design a kind of hardware ﹠ tools box of being convenient to change the box core, and it becomes easily the replacing of box core, has solved the problem that outer box and box core one make troubles and waste to use.

The technical solution of the utility model: a kind of hardware ﹠ tools box of being convenient to change the box core, syndeton and slip latch fitting at the bottom of comprising lid, box, at the bottom of box core, lid and the box, it is characterized in that the inboard symmetric position of surrounding edge at the bottom of said lid and the box is provided with the groove of connecting box core, bossed barb-like fin is located in the groove upper edge; Split at the bottom of said box core and lid, the box, connection groove at the bottom of the corresponding lid of box core, the box has the trough rim of projection, at the bottom of corresponding box is located in the trough rim upper edge, the barb-like fin of lid upper process has corresponding recessed rib, the box core be tight fit according to emboss pit and convex-concave rib at the bottom of lid, the box and be connected.

At the bottom of the above-mentioned said connecting box with at the bottom of the box of the slip latch fitting institute foundation of lid with lid on the curved shape of slide rail, it is a surface plate along jam plate that arc track slides.

Using method of the present utility model: will be connected with being tight fit according to the barb-like rib on emboss pit and the notch at the bottom of the lid of the box core of protruding trough rim and band recessed pockets, the box, can not come off with the lid place at the bottom of making the box core be contained in box, camber track on the latch fitting that slides simultaneously and plane tabular jam plate interact lock can be locked naturally in any position of track.

Superiority of the present utility model: 1, simple in structure, design ingeniously, solved the trouble that needs to change the box core, bring convenience and material benefit to the user; 2, jam plate and track can be tightened naturally, utilize mechanics principle to simplify the box lock construction dexterously, have reduced production cost.
