Description

Square button structure and packing carton

Technical Field

The utility model relates to a packing apparatus field especially relates to a square knot structure and packing carton.

Background

Patent CN110817144A provides a snap box which realizes the snap together of the whole box by the snap action of a first snap part (reference numeral 101 in the literature) and a second snap part (reference numeral 102 in the literature).

However, the buckle box disclosed in the above patent has a problem that the second engaging portion is semi-cylindrical, and in order to engage with the semi-cylindrical second engaging portion, the shape of the clamping groove must be semi-cylindrical, the semi-cylindrical clamping groove is matched with the semi-cylindrical second engaging portion, which has a very high requirement on the processing precision of the second engaging portion and the clamping groove, and the buckle box with the above structure is produced by a plastic suction method, such as the presence of foreign particles on a plastic film in the plastic suction production process, which may cause the second engaging portion or the clamping groove to be uneven, and the semi-cylindrical engaging portion or the clamping groove may cause the second engaging portion and the clamping groove to be unable to engage with each other as long as the unevenness occurs, so that the rejection rate of the buckle box provided in patent CN110817144A is high.

SUMMERY OF THE UTILITY MODEL

The arc sliding surface is arranged to reduce the sliding friction force when the first clamping hook and the second clamping hook are matched.

Optionally, the first engaging hook is L-shaped, and the second engaging hook is L-shaped.

Optionally, the first lock catch is a hollow first lock catch, the first engaging hook is a hollow first engaging hook, the second lock catch is a hollow second lock catch, and the second engaging hook is a hollow second engaging hook.

Optionally, the first lock catch is a plastic first lock catch, and the second lock catch is a plastic second lock catch.

A packing box comprises the square button structure.

Optionally, the packing carton still includes box bottom and lid, the lid rotates with the box bottom to cooperate together, first hasp is fixed on the lid integratively, second hasp is fixed on the box bottom integratively.

The structure of the specific packaging box is shown in patent CN 110817144A.

The utility model has the advantages that: the processing requirement is greatly reduced, the product rejection rate is low, and because of the plane laminating, the resistance when the first lock catch is separated from the second lock catch is smaller, and the opening is easier.

Description of the drawings:

figure 1 is a schematic diagram of a square button structure.

The figures are numbered: 1. the locking device comprises a first lock catch 101, a first clamping hook 2, a second lock catch 201, a second clamping hook 202, a clamping groove 3, an arc sliding surface 4 and an end surface.

The specific implementation mode is as follows:

the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, a square buckle structure includes a first buckle 1 and a second buckle 2, a first engaging hook 101 is disposed on the first buckle 1, a second engaging hook 201 and a slot 202 are disposed on the second buckle 2, the second engaging hook 201 is disposed in the slot 202, the first engaging hook 101 is used for being in snap fit with the second engaging hook 201, when the first engaging hook 101 is in snap fit with the second engaging hook 201, the first engaging hook 101 is disposed in the slot 202 of the second engaging hook 201, the slot 202 is a square slot 202, a part of the end surface 4 of the first engaging hook 101 is planar, and the first engaging hook 101 is attached to a slot wall of the slot 202 through its own planar end surface 4.

The shape of draw-in groove 202 is square in the above-mentioned structure, first block hook 101 pastes the cell wall of tight draw-in groove 202 through the planar terminal surface 4 of self, because the cell wall of draw-in groove 202 is also planar, so be the plane contact between first block hook 101 of the knot of this kind of structure and draw-in groove 202, and even there is certain unevenness in the surface in plane contact, first block hook 101 still can slide into and chucking in draw-in groove 202, so the buckle of this kind of structure has reduced the processing requirement by a wide margin, the product rejection rate is low, and owing to be the plane laminating, for the plane laminating, the plane laminating breaks away from more easily, when needing to make first hasp 1 break away from the cooperation with second hasp 2, the resistance when first hasp 1 breaks away from with second hasp 2 is littleer, it is changeed to open. Meanwhile, the contact area is reduced due to the plane contact, and the probability that the first clamping hook 101 is clamped in the clamping groove 202 is reduced.
