Meanwhile during the placement of individual layer lunch box, because buckle naturally droops, the placement of lunch box body is also counteracts that, use and above seem inconvenient.

The content of the invention

The purpose of this utility model is to provide a kind of buckle structure of clamping, is combined using the lock with opening and tenon part Overlap joint fix pattern, apply on the lunch box class product of multilayer build-up, the overlapping solved between its Multilayer lunch box body is fixed Problem.

To achieve the above object, the technical solution of the utility model is, a kind of lunch box with window lock, including lid and At least one layer of lunch box body, the upper outside of lunch box body generate at least two cuboid tenon parts, in being symmetrically and evenly distributed.Lid Outside and the lower outside except the external other lunch box bodies of the lunch box sheet of the bottom, generate the lock being connected with tenon part.Lock Button is hinged on lid or lunch box body, and opening is formed at its top, and opening is snapped onto on tenon part, make lid and lunch box body, on Formed a fixed connection between lower floor's lunch box body.

Catching on tenon part using the lock with opening makes the structure of levels lunch box body stable connection, due to lock " window " opening keeps the contact with tenon part in the form of laterally holding completely, and contact area is larger, it is necessary to which larger laterally pulls Power could disengage lock from tenon part.Therefore, the stability of its connection is strengthened.

Further, the lunch box with window lock of said structure, the lock length of lunch box body is itself and same lunch box The distance of the tenon part of body is identical.

Lock is hinged on lunch box body, and when it is not connected with tenon part, meeting nature is in hang, by Exceed the bottom surface of lunch box body in its length, the placement of lunch box body and appearance can be influenceed.The above-mentioned length by lock is it With the tenon part of same lunch box body apart from identical structure, it is possible to be rotated up lock, fasten on tenon part, be bonded meal The outer wall storage of box body.It is attractive in appearance and practical.

Preferably, the lunch box with window lock of said structure, the bottom edge position of tenon part generate one of bar shaped limit Position is raised.

Simultaneously it is also possible that the bottom surface of the opening of lock generates one of bar shaped snapping raised line.

The above-mentioned tenon part with spacing preiection is to make connection more stable：After lock catches on tenon part, spacing preiection Lock is formed in the outside of lock and hindered, is now disengaged lock from tenon part, it is necessary to bigger switching pulling force.Cause This, further, snapping raised line is generated in the bottom surface of lock, after lock catches on tenon part, snapping raised line enters the limit of tenon part The raised inner side in position, both are engaged, and the fixation for making to latch on tenon part is further stablized.

Can also be that the lunch box with window lock of said structure, the bottom surface of the opening of lock generates one of bar shaped snapping Groove, the size of groove are identical with the bar shaped spacing preiection of tenon part.

The snapping groove of the bottom surface generation of latch openings can house the spacing preiection of tenon part.When lock catches on tenon part, Spacing preiection enters in snapping groove, makes the contact surface increase of lock and tenon part, frictional resistance is bigger, and lock is just not easy from tenon Disengaged on part.

Window locking connection structure of the present utility model, overcomes the structural instability connected between existing Multilayer lunch box and knot The complicated deficiency of structure.The characteristics of being more prone to simple in construction, easy to use, production.
