Abstract

The utility model belongs to a connecting piece of a packing box, particularly a steel strip. A bottom board and side boards are connected with each other to form a strip-shaped board with an L-shaped section. Positioning teeth are uniformly arranged on the bottom board; communicating grooves are uniformly arranged on the bottom board at one side near the side board. The utility model is characterized in that the side board corresponding to the groove protrudes outwards to form a protruding part; a gap h is formed between the inner wall of the side board and the inner wall of the protruding part; therefore, the utility model is favorable to the operation of users.

Description

A kind of steel limit

The utility model belongs to a kind of attaching parts of packing chest, refers in particular to a kind of steel limit.

Along with the continuous minimizing of wildwood, the continuous deterioration of ecology environment, increasing people recognizes the excessive and random lumbering that must prevent natural forest, to preserve the ecological environment, so a kind of reusable packing chest has just arisen at the historic moment.

Usually in order to satisfy the operating needs of different occasions, thisly be referred to as the packing chest of REPAK by the foreigner, making at it in form can be different.Frame as some packing chest must connect two adjacent side plates with the steel hinge, and to improve the intensity of frame, whole packing chest is not provided with tongue piece, comes fastening each side plate and frame and bottom with the steel band packing at last; Some packing chest then adopts Steel tab and steel limit and connects steel band relevant boxboard is linked together, so that mounting or dismounting, discloses packing chest so a kind of as ZL95214291.0.Wherein the former intensity is better, but operation and transport cumbersomely, the latter then relatively flexibly is convenient to operation and transportation.

The purpose of this utility model is to design the steel limit that a kind of packing chest is used, and with handled easily, strengthens the repeat usage of different size interchangeability of parts, raising material.

Its main technical schemes is that base plate and side plate are linked to be the L-shaped strip plate of a section, uniform positioning teeth on base plate, at groove near uniform perforation on the base plate of side plate one side, it is characterized in that corresponding to the side plate at groove place outwards outstanding, form a protrusion, between the inwall of the inwall of side plate and protrusion, form a gap y.

Outward flange at side plate and protrusion forms a segmental arc, the center of circle of this segmental arc is positioned at the inboard, and at the flanging that the outward flange setting of base plate bends to the inside, it is fan-shaped that positioning teeth is, and directly on base plate, utilize stamping tool to be stamped to form, on base plate, stay scallop.

The utility model has the advantages that simple in structurely, make with easy to use that various structures on the steel limit directly are stamped to form by steel plate, the degree of utilization of material is higher.During use with the registration finger on the base plate of steel limit on the plane at boxboard edge, the side plate on steel limit wraps in the side of boxboard, make the inwall of side plate be close to the side of boxboard, form gap y between the protrusion inwall on the side plate and the side of boxboard, so that the head of Steel tab inserts in it, and in the prior art, because of there not being this gap y, the insertion of tongue piece takes out all very difficulty during installation; In addition, there is not groove in the prior art, a but slotted eye, the structure in this hole also is unfavorable for the use of tongue piece, after in the utility model, having adopted long and narrow channel shaped structure, corresponding with flat tongue piece, can be when guaranteeing to operate tongue piece easily, reduce the area of groove as much as possible, to avoid because of offering the decline problem of the caused steel of groove limit intensity; After the outward flange of side plate and base plate is provided with aduncate segmental arc and flanging respectively, make on the steel limit sharp edges after installation all towards a side of boxboard, the hand of having avoided the operator is because of running into the problem that sharp edge, steel limit scratches skin.

This steel buckle is convenient to normalisation in addition, if loss or damage are arranged, promptly gives and changes or replenish in the use.

Fig. 1 is a constructional drawing of the present utility model.

Fig. 2 is the A-A view of Fig. 1.

As shown in the figure:

Base plate 4 is linked to be the L-shaped strip plate of a section with side plate 1, uniform positioning teeth 5 on base plate 4, at groove 2 near uniform perforation on the base plate 4 of side plate 1 one sides, for ease of using tongue piece, side plate 1 corresponding to groove 2 places is outwards outstanding, on side plate 1, form a protrusion 3, between the inwall of the inwall of side plate 1 and protrusion 3, form a gap y, outward flange at side plate 1 and protrusion 3 is provided with a segmental arc 8, the center of circle of this segmental arc is positioned at the inboard, with after guarantee installing, its sharp edges is towards boxboard, the flanging 7 that bends to the inside in the outward flange setting of base plate 4, to avoid stabbing operator's skin, positioning teeth 5 is fan-shaped, and directly utilizes stamping tool to be stamped to form on base plate 4, stays a scallop 6 on base plate 4.

Claims

1, a kind of steel limit, be linked to be the L-shaped strip plate of a section by base plate (4) and side plate (1), go up uniform positioning teeth (5) at base plate (4), at the groove (2) of going up uniform perforation near the base plate (4) of side plate (1) one side, it is characterized in that the side plate of locating corresponding to groove (2) (1) is outwards outstanding, form a protrusion (3), between the inwall of the inwall of side plate (1) and protrusion (3), form a gap y.

2, steel according to claim 1 limit is characterized in that forming a segmental arc (8) at the outward flange of side plate (1) and protrusion (3), and the center of circle of this segmental arc is positioned at the inboard.

3, steel according to claim 1 limit is characterized in that the flanging (7) that the outward flange setting at base plate (4) bends to the inside.

4, steel according to claim 1 limit is characterized in that positioning teeth (5) is fan-shaped, and directly utilizes stamping tool to be stamped to form on base plate (4), stays scallop (6) on base plate (4).
