Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figures 1 to 7 This utility model provides a technical solution:

[0026] A stackable turnover box includes a box 1, limiting holes 2, alignment baffles 3, a horizontal movable mounting bracket 4, baffles 5, a lifting column assembly 6, and limiting pins 8. Limiting holes 2 are provided at both the upper and lower ends of the box 1. Figure 1 and 4 As shown, the limiting holes 2 at the upper and lower ends of box 1, and at corresponding positions, are concentric in the vertical direction. The centers of the limiting holes 2 at the ends of box 1, and located on the same side, are on the same horizontal reference line. Figure 7 As shown, the limiting holes 2 are arranged in such a way that when the boxes 1 are stacked, the limiting holes 2 at the lower end of the upper box 1 are concentric with the limiting holes 2 at the upper end of the lower box 1, wherein:

[0027] Alignment baffle 3 is located on the side of box 1 and at the top of box 1. Alignment baffle 3 facilitates the alignment of boxes 1 when stacked. Horizontal movable mounting bracket 4 is horizontally and movably mounted inside box 1 via a keyway. Horizontal movable mounting bracket 4 acts as a sliding pair inside box 1. A baffle 5 is provided on horizontal movable mounting bracket 4 to drive the horizontal movable mounting bracket 4 to move. An elastic component is provided between baffle 5 and alignment baffle 3; by providing the elastic component, baffle 5 can be reset. After alignment baffle 3 is compressed to its maximum position, the upper and lower boxes 1 can be aligned and stacked.

[0028] The lifting column assembly 6 includes a limiting column 61 and a spring II 62. The limiting column 61 is vertically movable within a mounting hole on the horizontal movable mounting frame 4 via the spring II 62. The limiting column 61 forms a vertically moving pair within the mounting hole on the horizontal movable mounting frame 4. The center of the limiting column 61 is on the same horizontal reference line as the center of the limiting hole 2 on the same side, allowing the limiting column 61 to extend out of the limiting hole 2 when it moves below it. When the horizontal movable mounting frame 4 causes the limiting column 61 to be concentric with the limiting hole 2 at the upper end of the housing 1, the limiting column 61 will move upward under the elastic force of the spring II 62, thus passing through the limiting hole 2 at the upper end of the housing 1. Figure 7As shown, when the limiting post 61 inside the lower box 1 extends out of the limiting hole 2 at the upper end of the box 1, the limiting post 61 inside the lower box 1 will be inserted into the limiting hole 2 at the lower end of the upper box 1, thereby fixing the stacked boxes 1.

[0029] The unlocking component 7 is installed inside the box 1, and the end of the unlocking component 7 cooperates with the limit post 61.

[0030] In a preferred embodiment, the elastic component includes a guide post 51 and a spring I 52. The guide post 51 is provided on the side of the baffle 5, and the spring I 52 is located between the guide post 51 and the alignment baffle 3. One end of the spring I 52 is located inside the alignment baffle 3, and the other end is connected to the guide post 51. The elastic force of the spring I 52 can serve as the power for resetting the horizontal movable mounting bracket 4. When the boxes 1 are stacked, pushing one of the boxes 1 causes it to move along the alignment baffle 3 on the upper end of another box 1. At this time, the upper box 1 will gradually squeeze the horizontal movable mounting bracket 4 on the lower box 1, thereby driving the lifting column assembly 6 on the lower box 1 to move.

[0031] In a preferred embodiment, the unlocking component 7 includes a vertical movable mounting bracket 71 and a switch rod 72. The vertical movable mounting bracket 71 is vertically movable inside the box 1, and forms a vertical sliding joint inside the box 1. The lower end of the limiting post 61 passes through the horizontal movable mounting bracket 4 and is movably engaged with the vertical movable mounting bracket 71. The limiting post 61 forms a horizontal sliding joint on the vertical movable mounting bracket 71. Therefore, the limiting post 61 can not only move on the vertical movable mounting bracket 71 but also rise and fall vertically with the vertical movable mounting bracket 71. The switch rod 72 is located on the vertical movable mounting bracket 71 and passes through the side of the box 1. Pulling the switch rod 72 up and down can cause the limiting post 61 to move up and down synchronously.

[0032] In a preferred embodiment, the limiting pin 8 is movably mounted on the side of the box 1, located above the switch rod 72. When it is necessary to release the stacked boxes 1, simply pull down the switch rod 72, which in turn moves the limiting post 61 downwards, causing the limiting post 61 to disengage from the limiting hole 2 at the lower end of the stacked box 1 above it. Then, pull the limiting pin 8 to lock the switch rod 72, preventing the switch rod 72 from moving upwards under the elastic force of the spring 62. At this point, the stacked boxes 1 are released, and the upper box 1 can be removed.

[0033] The working principle of this utility model:

[0034] When it is necessary to stack boxes 1, simply push one of the boxes 1 so that it moves along the alignment baffle 3 on the top of the other box 1. At this time, the upper box 1 will gradually squeeze the horizontal movable mounting bracket 4 on the lower box 1, thereby driving the lifting column assembly 6 on the lower box 1 to move.

[0035] When the movable horizontal mounting bracket 4 moves the lifting column assembly 6 to the point where the limiting column 61 is concentric with the limiting hole 2 at the upper end of the box 1, the limiting column 61 will move upward under the elastic force of the spring II 62, and then pass through the limiting hole 2 at the upper end of the box 1. Figure 7 As shown, when the limiting post 61 inside the lower box 1 extends out of the limiting hole 2 at the upper end of the box 1, the limiting post 61 inside the lower box 1 will also insert into the limiting hole 2 at the lower end of the upper box 1, thereby fixing the stacked boxes 1.

[0036] When it is necessary to release the stacked boxes 1 from their fixation, simply pull down the switch lever 72, which in turn moves the limiting post 61 downwards, causing the limiting post 61 to disengage from the limiting hole 2 at the bottom of the stacked box 1 above it. Then, pull the limiting pin 8 to lock the switch lever 72, preventing it from moving upwards under the force of the spring 62. At this point, the stacked boxes 1 are released from their fixation, and the upper box 1 can be removed.

[0037] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
