Obviously, for those of ordinary skill in the art, the other drawings can be obtained based on these drawings without any creative effort.

For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0035] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the examples in the description are only part of the embodiments of the present application, not all the embodiments.

[0036] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. Embodiment 1

[0037] Referring to Figures 1 to 5 , the embodiment provides a foldable stacking positioning structure, which comprises a base 1, a rotating shaft 2 and a positioning pin shaft 3; the base 1 comprises a bottom plate 11 and a hinge seat 12, the bottom plate 11 is adapted to be fixed on a box body, and the hinge seat 12 is fixed on the bottom plate 11; the rotating shaft 2 is installed on the hinge seat 12 and parallel to the bottom plate 11; the positioning pin shaft 3 is fixed on the rotating shaft 2 and perpendicular to the rotating shaft 2, and the positioning pin shaft 3 has a working state perpendicular to the bottom plate 11 and extending outward from the hinge seat 12 away from the bottom plate 11, and a folding state parallel to the bottom plate 11.

[0038] As Figure 3 shown, the bottom plate 11 is fixed on the box body by the following structure:

[0039] The corner of the bottom plate 11 is provided with a mounting hole 111, and the bottom plate 11 is adapted to be fixed on the box body by the screw 5 penetrating through the mounting hole 111. The fixing of the bottom plate 11 on the box body is realized by the screw 5, which is simple in structure and firm in fixing.

[0040] Specifically, the bottom plate 11 is rectangular, and the four corners of the bottom plate 11 are provided with mounting holes 111.

[0041] As Figure 3 shown, the hinge seat 12 adopts the following structure:

[0042] The hinged seat 12 comprises two hinged plates 121 arranged oppositely and perpendicularly to the bottom plate 11, and a mounting area 122 is left between the two hinged plates 121; the rotating shaft 2 is inserted into the two hinged plates 121, and the positioning pin shaft 3 is fixed to the part of the rotating shaft 2 corresponding to the mounting area 122. The two hinged plates 121 support the two ends of the rotating shaft 2 respectively, and the structure is more stable. In other embodiments, only one hinged plate 121 can be arranged, and the rotating shaft 2 forms a cantilever structure.

[0043] Further, as shown in Figure 3 , the hinged seat 12 further comprises a connecting plate 124, which forms a U-shaped structure with the two hinged plates 121, and the connecting plate 124 is fixed to the bottom plate 11. Compared with the scheme of directly fixing the hinged plate 121 to the bottom plate 11, the hinged seat 12 is additionally provided with the connecting plate 124, which is connected to the bottom plate 11 to realize the connection between the hinged seat and the bottom plate 11, and the connection is more convenient, the contact area is larger, and the fixation is more stable.

[0044] Specifically, the connecting plate 124 can be fixed to the bottom plate 11 by using fasteners or adhesives or welding and the like.

[0045] Specifically, as shown in Figure 1 , in order to further increase the contact area, the embodiment further provides a protrusion on the bottom surface of the connecting plate 124, and a positioning hole is provided on the top surface of the bottom plate 11, and the protrusion is fitted into the positioning hole.

[0046] As shown in Figure 2 , Figure 4 and Figure 5 , the positioning pin shaft 3 is fixed to the rotating shaft 2 by the following structure:

[0047] The positioning pin shaft 3 is fixed to the rotating shaft 2 through a shaft sleeve 4, the shaft sleeve 4 comprises a sleeve 41 and a screw rod 42, the sleeve 41 is sleeved and fixed to the rotating shaft 2, the screw rod 42 is perpendicular to the sleeve 41, the positioning pin shaft 3 is provided with a threaded hole 31 coaxial with the positioning pin shaft 3, and the screw rod 42 is screwed into the threaded hole 31.

[0048] During installation, the shaft sleeve 4 is first sleeved and fixed to the rotating shaft 2, and then the positioning pin shaft 3 is screwed to the screw rod 42 through the threaded hole 31. The installation is relatively convenient; and the height of the working section of the positioning pin shaft 3 can be adjusted by screwing the positioning pin shaft 3, so as to adjust the stacking gap.

[0049] It should be noted that the threaded hole 31 is preferably designed as a blind hole on the end face of the positioning pin shaft 3 close to the bottom plate 11, which has higher structural strength; or it can be designed as a through hole.

[0050] Specifically, as shown in Figure 2As shown, the sleeve 41 is fitted onto the rotating shaft 2 with a clearance and is fixed relative to the rotating shaft 2 by the cylindrical pin 43. It should be noted that the cylindrical pin 43 is inserted into both the rotating shaft 2 and the sleeve 41 by an interference fit.

[0051] Specifically, such as Figure 4 As shown, the top of the positioning pin 3 is a tapered part, which can guide the positioning pin 3 into the positioning hole of the adjacent upper housing, making assembly easier.

[0052] Specifically, the sleeve 41 and the screw 42 are integrally formed. In other embodiments, the sleeve 41 and the screw 42 may also be fixedly connected as one piece by welding or other means.

[0053] Furthermore, such as Figure 3 and Figure 4 As shown, the end of the positioning pin 3 near the rotating shaft 2 protrudes outward to form an arc-shaped retaining edge 32. A groove 123, adapted to the retaining edge, is provided on the end face of the hinge plate 121 away from the base plate 11. When the positioning pin 3 is in the working state, the arc-shaped retaining edge 32 is engaged in the groove 123. When the positioning pin 3 is in the working state, the cooperation between the arc-shaped retaining edge 32 and the groove 123 can limit the positioning pin 3, preventing it from rotating around the rotating shaft 2 and keeping it in the working state. When the positioning pin needs to be adjusted to the folded state, first, the positioning pin 3 is rotated in the opposite direction to disengage the arc-shaped retaining edge 32 from the groove 123, and then the positioning pin 3 is rotated around the rotating shaft 2 to the folded state.

[0054] It should be noted that the arc-shaped retaining edge 32 refers to the structure of the part that mates with the slot 123. The reason for designing it as arc-shaped is to allow the positioning pin 3 to rotate even when the arc-shaped retaining edge 32 is placed in the slot 123. As for the part between the two hinge plates 121, an arc-shaped retaining edge 32 can be provided to make the entire arc-shaped retaining edge a complete circle; alternatively, the arc-shaped retaining edge 32 can be omitted; or it can be... Figure 1 The curved flange 32 is replaced with a straight flange, as long as this part of the structure does not interfere with the slot 123 when rotating the positioning pin 3.

[0055] It should be noted that when the positioning pin 3 is in the folded state, its gravity can prevent large-scale shaking; alternatively, by screwing the positioning pin 3, the arc-shaped stop 32 can be pressed against the side of the hinge plate 121, thereby preventing the positioning pin 3 from shaking.

[0056] like Figure 2 As shown, the rotating shaft 2 is mounted on the hinge seat 12 by the following structure:

[0057] The rotating shaft 2 is inserted into two hinge plates 121 with gaps, and both ends extend outward from the corresponding hinge plates 121. One end of the rotating shaft 2 is provided with a shoulder 21, and the other end is equipped with an elastic retaining ring 22.

[0058] During installation, the end of the rotating shaft 2 without the shoulder 21 is sequentially passed through two hinge plates 121, so that the shoulder 21 is locked onto the outside of the corresponding hinge plate 121. Then, an elastic retaining ring 22 is installed on the end of the rotating shaft 2 without the shoulder 21 to prevent the rotating shaft 2 from falling off axially. The rotation of the rotating shaft 2 is achieved through its clearance assembly. Installation is relatively convenient and disassembly and replacement are easy.

[0059] It is easy to understand that a mounting groove needs to be opened at the end of the rotating shaft 2 where the shoulder 21 is not provided, and the elastic retaining ring 22 is fitted into the mounting groove to prevent the elastic retaining ring 22 from falling off.

[0060] The working principle of the foldable stacking and positioning structure in this embodiment is as follows:

[0061] First, attach and fix the base plate 11 to the top surface of the box. Positioning holes corresponding to the positioning pins 3 are made on the bottom surfaces of adjacent upper boxes. During stacking and positioning, rotate the positioning pins 3 to the working state, and then insert them into the positioning holes on the bottom surfaces of adjacent upper boxes to achieve relative horizontal fixation of the two boxes. When folding or unfolding the boxes, first reverse the rotation of the positioning pins 3 to disengage the arc-shaped stop 32 from the slot 123, and then rotate the positioning pins 3 around the pivot 2 to the folded state. Example 2

[0062] This invention provides a box body, including a box body with a foldable stacking and positioning structure as described in Embodiment 1 installed on the top surface of the box body, and a positioning hole adapted to the positioning pin 3 on the bottom surface of the box body. The box body can be positioned with adjacent upper-layer boxes through the foldable stacking and positioning structure on the top surface, or with adjacent lower-layer boxes through the positioning hole on the ground, thus enhancing its versatility.

[0063] Specifically, the positioning holes are preferably designed as blind holes; when it does not affect the use of the enclosure, they can also be designed as through holes.

[0064] Furthermore, a receiving groove is provided on the top surface of the box body, the base 1 is fixed in the receiving groove, and the positioning pin 3 extends out of the receiving groove when in the working state and is placed in the receiving groove when in the folded state. When the positioning pin 3 is in the folded state, the positioning pin 3 and the base 1 can be completely placed in the receiving groove, thereby completely freeing up the external space of the box body.

[0065] The above are merely specific embodiments of the present invention, enabling those skilled in the art to understand or implement the present invention. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and they should all be covered within the protection scope of the claims.
