Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a packaging box with an automatic resetting function. Background Art

[0002] In addition to simple cleaning products, cosmetics are substances used to enhance the beauty of the human body. With the continuous improvement of people's living standards, the use of cosmetics and cosmetics is becoming more and more frequent, so the demand for cosmetics and cosmetics packaging boxes is also increasing.

[0003] For example, a packaging box with an automatic reset function disclosed in a Chinese patent document (Announcement No.: CN221341554U) uses an automatic reset mechanism for the drawer. When in use, the drawer body is pulled out by pulling the handle. At this time, the reset spring is stretched. After the makeup or cosmetics in the drawer body are taken out, the handle is released. Under the elastic force of the reset spring, the drawer body is automatically reset, which saves the time of closing the drawer body, makes it easier to take out makeup or cosmetics, and helps to enhance the user experience; when the drawer body is not needed to be automatically retracted, the fixed plate at the rear of the drawer body can be aligned with the limit slot. Under the elastic force of the limit spring, the limit rod extends out and clamps the limit slot to limit the drawer body. This setting can be used when the user needs to open the drawer for a long time, which is very practical.

[0004] However, when the drawers are opened for a long time, they need to be pulled to the limit before they can be locked. Since items in multiple drawers are used when applying makeup, when all drawers are opened, the drawers above them will block the drawers below them. It is impossible to open the multiple drawers in a step-by-step manner to the appropriate distance and position them according to usage needs, which makes it inconvenient to use and has low practicality.

[0005] Therefore, we propose a packaging box with automatic reset function. Utility Model Content

[0029] Example 1

[0030] like Figure 1-6 As shown, the utility model provides a technical solution: a packaging box with an automatic reset function, comprising a packaging box body 1, a cover body 2 hingedly connected to the back of the packaging box body 1 by a hinge, movable slots distributed in a linear array are opened on the front of the packaging box body 1, a drawer box 3 is movably inserted into the inner wall of the movable slot, and positioning grooves 4 distributed in a linear array are opened on the lower surface of the drawer box 3, and mounting cavities 5 distributed in a linear array are opened inside the packaging box body 1, and the inner bottom wall of the mounting cavity 5 is fixedly connected to symmetrically distributed guide rods 6, one end of each of the two guide rods 6 is fixedly connected to the inner top wall of the mounting cavity 5, and the outer surfaces of the two guide rods 6 are movably sleeved with a lifting plate 7, and the guide rods 6 play a role in guiding and limiting the movement of the lifting plate 7;

[0031] The upper surface of the lifting plate 7 is provided with a movable positioning device, and the movable positioning device includes an inclined surface plug-in block 8 , the lower end of the inclined surface plug-in block 8 is fixedly connected to the upper surface of the lifting plate 7 .

[0032] Example 2

[0033] like Figure 1-6As shown, the utility model provides a technical solution: the upper end of the inclined plug block 8 passes through and extends to the inside of the movable slot, the upper end of the inclined plug block 8 is movably plugged into the inner wall of one of the positioning grooves 4, and the lower surface of the lifting plate 7 is fixedly connected with symmetrically distributed return springs 81. The elastic force of the return spring 81 drives the inclined plug block 8 to return and move upward through the lifting plate 7.

[0034] One end of the two return springs 81 is fixedly connected to the inner bottom wall of the mounting cavity 5, and an extrusion roller 82 is provided at one end of the lifting plate 7. Movable holes distributed in a linear array are opened on the front of the packaging box body 1. The extrusion roller 82 reduces the extrusion friction on the lifting plate 7 by rolling.

[0035] One end of the movable hole is connected to the front inner wall of the installation cavity 5, and a driving rod 83 is movably sleeved on the inner wall of the movable hole. One end of the driving rod 83 is fixedly connected to a pressing block 84. The pressing block 84 increases the pressing area to facilitate pressing and moving the driving rod 83.

[0036] The other end of the driving rod 83 is fixedly connected to a driving block 85 , and one side surface of the driving block 85 is fixedly connected to symmetrically distributed extrusion bevel blocks 86 . The driving rod 83 drives the extrusion bevel blocks 86 to move through the driving block 85 .

[0037] The inclined surfaces of the two extrusion bevels 86 are in rolling contact with the outer surface of the extrusion roller 82. The inner walls of the movable slots are provided with symmetrically distributed guide grooves 87. The inner walls of the guide grooves 87 are slidably connected with guide sliders 88. The inclined surfaces of the extrusion bevels 86 are rolled and extruded with the extrusion roller 82, thereby reducing the effect of extrusion friction.

[0038] The opposite surfaces of the two guide sliders 88 are fixedly connected to the two side surfaces of the drawer box 3 respectively, and the back of the guide slider 88 is fixedly connected with a contraction spring 89. The elastic force of the contraction spring 89 drives the drawer box 3 to automatically store and reset. One end of the contraction spring 89 is fixedly connected to the rear inner wall of the guide slide groove 87.

[0039] By moving the positioning device, it is possible to automatically limit the drawer box 3 after it is pulled out to any distance, so that multiple drawer boxes 3 can be placed in a stepped manner after being pulled out, avoiding mutual obstruction between the drawer boxes 3, which is convenient for use, and the automatic reset by pressing is greatly improved, which greatly improves the convenience during use and thus improves the practicality.

[0040] The working process of this utility model:

[0041] When the drawer box 3 is in use, the handle on the drawer box 3 is used to pull it out. When the drawer box 3 moves, it moves stably through the cooperation of the guide slide 87 and the guide slider 88, and the movement of the guide slider 88 drives the contraction spring 89 to stretch and store energy, and when the drawer box 3 moves, the inclined surface of the inclined surface plug 8 is squeezed through the positioning groove 4, so that the inclined surface plug 8 is moved downward through the lifting plate 7. When the drawer box 3 moves to the appropriate position, the restoring elastic force of the return spring 81 drives the lifting plate 7 to rise and reset through the guiding cooperation of the guide rod 6. The rising movement of the lifting plate 7 drives the inclined surface plug 8 to insert into the corresponding positioning groove 4, and the flat end of the inclined surface plug 8 cooperates with the positioning groove 4 to limit the drawer box 3, thereby resisting the elastic force of the contraction spring 89.

[0042] The second step is to press the corresponding pressing block 84 under the drawer box 3 after use. The movement of the pressing block 84 drives the driving block 85 to move through the driving rod 83. The movement of the driving block 85 drives the extrusion bevel 86 to move. The movement of the extrusion bevel 86 continuously squeezes the extrusion roller 82 through its inclined surface, so that the extrusion roller 82 drives the lifting plate 7 and the inclined surface insert block 8 to move downward. When the inclined surface insert block 8 is out of the positioning groove 4, the drawer box 3 is reset and stored by the elastic force of the contraction spring 89 and the guide slider 88, and then the pressing block 84 is released. At this time, the elastic force of the reset spring 81 drives the inclined surface insert block 8 to move upward and insert into the corresponding positioning groove 4 for limiting. The rising movement of the lifting plate 7 squeezes the extrusion bevel 86 in the opposite direction, so that the pressing block 84 is reset.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
