Abstract

The invention relates to a two-way lock catch device for connecting two panels together and a paper sleeve. The two-way lock catch device comprises two lock catches, wherein a first concave tongue piece is folded out from the plane of a first panel, a hole is formed in the first panel, a second concave tongue piece is folded into the hole, and an included angle is formed between the second concave tongue piece and the first concave tongue piece, so that a first lock catch is formed; and a convex tongue piece B is folded along with the second concave tongue piece, a gap is formed between the convex tongue piece B and a convex tongue piece A, and the first convex tongue piece is inserted from the gap so as to be clamped by a butt joint type tongue piece mechanism, so that a second lock catch is formed. Compared with the prior art, stable connection between the two panels is achieved, and the two-way lock catch device is more compact in structure through the ingenious combination design of the concave and convex tongue pieces.

Description

technical field [0001] The invention relates to the field of packaging, in particular to a two-way locking device and a paper sleeve for connecting two panels together. Background technique [0002] The lap connection of two panels usually adopts panel interlocking structure. A common locking device is to form a locking tongue on one panel and a locking hole on the other panel, insert the locking piece into the locking hole, and match the edge of the locking tongue with the edge of the locking hole. Form a panel interlocking structure. This panel interlocking structure has poor performance in terms of stability. Contents of the invention [0003] The object of the present invention is to provide a two-way locking device and a paper sleeve for connecting two panels together in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] The invention prov...
