Description
Technical Field
The utility model belongs to the carton packing field specifically is a drawer box cut-parts with open limit structure to and the drawer box of being made by this cut-parts.
Background
The drawer box is a common paper box variety and comprises a shell and a box body, wherein the shell is of a straight cylinder type, the box body is inserted in the shell in an adaptive mode, and the box body is pulled out from the shell to expose contents. Chinese patent document CN203005915U discloses a drawer-type box in 2013, 6/19/h, which includes a casing (1) with an opening at one end, a drawer box (2) capable of being drawn out and pushed in is further provided in the casing (1), and a notch (11) for facilitating the drawing out of the drawer box (2) is provided at the edge of the casing (1). An opening of the shell (1) is provided with an inward flanging (12). The bottom of the drawer box (2) is provided with a blocking sheet (21) which can be inserted into a flanging (12) to prevent the drawer box (2) from being separated from the shell (1). The drawer box (2) is a hollow chamber which is formed by bending a paperboard and then pasting the paperboard and has a side wall with a certain thickness. The bottom of the shell (1) is provided with a blocking piece (13), a bottom cover (14) matched with the blocking piece (13) and used for sealing the bottom opening of the shell (1) is further arranged, a locking bolt (141) is arranged on the bottom cover (14), and a pasting edge (15) is further arranged on one side of the shell (1). For the traditional drawer box, no limit structure is arranged in the drawing and pushing stroke of the box body, and the box body cannot be accurately controlled to be positioned at a specific drawing degree. This drawback limits the use of the drawer box in certain applications. For example, when in the vertical state, if the housing is loose, the housing may slide down due to gravity to completely cover the cartridge, and the cartridge may not be in a partially exposed state; if the shell is compact and the friction force with the box body is large, the shell can not fall down due to gravity, but the shell is moved to a target position accurately, and the box body is still difficult to be in a preset local exposure state.

The present invention will be further described with reference to the accompanying drawings and the detailed description.
The embodiment relates to a drawer box cut piece with an opening limiting structure, which is made of white cardboard.
The panels of this example include an outer shell panel and a box panel. As shown in fig. 1, the shell cutting piece is provided with a shell rear plate T1, a shell left plate T2, a shell front plate T3 and a shell right plate T4 which are connected in sequence from left to right, and the left side of the shell rear plate T1 is also connected with a shell connecting plate T5 for adhesion. The adjacent parts are connected by a longitudinally extending longitudinal shell crease line 1. The box body cut-parts are as shown in figure 2, and comprise a centered bottom plate A, the bottom plate A is rectangular, and an upper side plate component B, a lower side plate component C, a left side plate component D and a right side plate component E are respectively connected to four sides of the upper side, the lower side, the left side and the right side. The box body cut-parts are of traditional structures, and the folded box body is of a traditional box shape with 5 faces and a cuboid shape. The outer shell cutting pieces form a straight cylinder shape matched with the box body after the bonding is finished.
The shell is provided with an opening limit structure. The opening restricting structures of this example are arranged on the housing front plate T3 in bilateral symmetry. For economy, only the opening limit structure on the left side is described below.
The opening limiting structure comprises an upper transverse tangent 2, a lower transverse tangent 2, a left auxiliary crease line and a right auxiliary crease line 3. The auxiliary crease lines 3 are straight lines parallel to the longitudinal crease lines 1 of the housing, the upper end of one auxiliary crease line 3 is positioned on the upper side of the front housing plate T3, the lower end of the auxiliary crease line is positioned inside the front housing plate T3, the upper end of the other auxiliary crease line 3 is positioned on the upper side of the left housing plate T2, and the lower end of the other auxiliary crease line 3 is positioned inside the left housing plate T2. The two auxiliary crease lines 3 are equally long. The transverse tangent 2 is a straight line perpendicular to the longitudinal crease line 1 of the shell, the two ends of the transverse tangent are respectively intersected with one auxiliary crease line 3, and the middle part of the transverse tangent is intersected with the longitudinal crease line 1 of the shell. In this example, the midpoint of the transverse tangent 2 is the intersection point where the transverse tangent 2 intersects the housing longitudinal fold line 1. The upper transverse tangent line 2, the lower transverse tangent line 2, the left auxiliary crease line 3, the upper side edge of the shell longitudinal crease line 1, the upper side edge of the shell left plate T2 and the upper side edge of the shell front plate T3 divide the paper board in the enclosed area into an upper part and a lower part, each part is divided into two parts which are bilaterally symmetrical, and the 4 parts are respectively marked as a side plate upper folding piece Z1, a front plate upper folding piece Z2, a side plate lower folding piece Z3 and a front plate lower folding piece Z4.

The front board T3 of the case faces forward, and the opening restricting structure is located at the upper left and upper right.
When the drawer box needs to be opened partially, the shell is pulled upwards to a proper height, and then the folding piece above the transverse tangent line 2 corresponding to the required height is bent inwards as required. As shown in fig. 4, the inward bending at this time is the side plate upper folding piece Z1 and the front plate upper folding piece Z2, which are bent inward to form a limiting structure and are lapped on the upper side plate component B of the box body, so that the further falling of the outer shell can be prevented, a preset gap below the box body is exposed, and the contents can automatically slide out from the preset gap or be taken out for use by a user. If the size of the exposed gap needs to be increased further, the shell can be lifted upwards, and the lower folding piece of the Z3 side plate and the lower folding piece of the Z4 front plate are bent inwards.
