[0044] like Figure 4 , Figure 5 As shown, the base 11 includes a base plate 111 and a frame 112. The base plate 111 is a rectangular plate with a through hole in the center and a plurality of slots on the periphery of the body. The frame 112 includes a transverse bone, a longitudinal bone and a gate-shaped bone; the transverse bone is a strip-shaped bone with a clamping protrusion at the bottom and top, a cross groove at the end and an avoidance groove at the top; the longitudinal bone is a strip-shaped bone with a clamping protrusion at the bottom and top, a cross groove at the end and an avoidance groove at the bottom; and a positioning protrusion is provided in the middle of the gate-shaped bone. When assembling the base 11, the transverse bone and the longitudinal bone are respectively inserted into the corresponding slots at the edge of the base plate through the clamping protrusions at the bottom, and a pair of gate-shaped bones are arranged crosswise and inserted into the slots at the oblique angle of the base plate, and then the reinforcing plate 14 is inserted outside the clamping protrusions on the top of the transverse bone and the longitudinal bone to improve the integrity. After the base is assembled, the assembly parts of the side plate 12 and the top plate 13 are installed around the base.

[0045] like Figure 6 , Figure 7 As shown, the side panel 12 includes an outer panel 121, a bracket 122, an inner panel 123, a storage cabinet 124 and a lock 125. The outer panel 121 is a rectangular panel, with a mortise at the top for assembling the top panel 13, a through hole at the bottom for installing the lock 125, a through hole in the middle, and a plurality of mortises at the periphery of the entity for assembly with the bracket 122. One end of the bracket 122 is connected to the outer panel by mortise and tenon, and the other end is connected to the inner panel 123 by mortise and tenon. A through hole is provided on the entity of the inner panel 123, and the inner panel is detachably connected to the outer panel through the bracket, and a storage space is formed between the two panels. The storage cabinet 124 is placed in the storage space for use, and the outer end surface of the cabinet extends to the outside of the through hole of the outer panel. The lock 125 is used to control whether the storage cabinet can be dragged out. The four side panels can be set to be the same, or different shapes can be set on their outer walls according to different functions to better develop the plot. The outer surface of each side panel can be set as follows Figure 8 shown.

[0046] like Fig. 9As shown, the lock head 125 includes an inner mounting plate 1251, a lock tongue 1252, an outer limiting plate 1253 and a pair of rotating shaft plates 1254. The inner mounting plate 1251 is a circular plate, and a positioning hole is provided at the center of the circle, and mounting holes are provided at both ends of the positioning hole. A rectangular hole is provided at one end of the lock tongue 1252, and an extension groove is provided at the center of the four sides of the rectangular hole. The outer limiting plate 1253 is a circular plate, and a cross groove is provided at the center. The rotating shaft plate 1254 is C-shaped, wherein a groove is provided at the middle of the outer end of one rotating shaft plate, and a groove is provided at the middle of the inner end of the other rotating shaft plate. The two rotating shaft plates are mutually engaged with the grooves to form a cross-shaped rotating shaft. The inner mounting plate 1251, the lock tongue 1252 and the outer limiting plate 1253 are coaxially clamped outside the cross-shaped rotating shaft. By twisting the cross-shaped rotating shaft, the lock tongue can be driven to rotate, thereby realizing the locking or unlocking of the storage cabinet 124; the lock head is assembled on the bracket through the inner mounting plate. After the side panels are assembled, the ear plates 15 connected to the bottom of the outer panels by mortise and tenon joints are assembled with the base. After each side panel is fitted with the longitudinal or transverse bones through the ear plates, it is hinged through a cross axis passing through the ear plates and the cross grooves, so that the side panels can rotate around the cross axis, and the release or locking of the rotational freedom is controlled by the top plate 13 and the tower head 3.

[0047] like Fig.10 As shown, the top plate 13 is a laminated plate, including a bottom plate 131, a secondary plate 132, a secondary plate 133 and a surface plate 134. Fig.11 As shown, the bottom plate 131 is a triangle, with a tenon at its bottom, an arc opening at its top corner, and a positioning groove on its body. The secondary plate 132 is a triangle, with a tenon at its bottom, a circular hole and a positioning groove on its body, and a notch connected to the circular hole at its top corner. The secondary panel 133 is a triangle, with a tenon at its bottom, a through hole and a positioning groove on its body, and an arc opening at its top corner, and a clamping arm 135 is provided on the arc opening. The surface plate 134 is a triangle, with a tenon at its bottom, a through hole and a positioning groove on its body, and a circle of identification grooves 136 outside the through hole. When the top plates are superimposed, the plates are aligned and bonded. After bonding is completed, the tenon at the bottom of the top plate is engaged with the tenon at the top of the side plate and then bonded as a whole. The top plate is limited by the clamping arm 135 after the top corner is engaged with the tower head 3, and is limited by the locking assembly 16 placed in the through hole. In actual design, the identification grooves outside the surface panels of each top panel can be designed to be the same or different, so as to facilitate the setting of various plots and enhance the interest.

[0048] like Fig.12 As shown, the locking assembly 16 includes a locking plate 161 and a locking head 162 that drives the locking plate to rotate. The locking plate 161 is a circular plate with a cross hole in the center and a crescent-shaped notch on the edge to lock and limit with the tower head 3. The locking head 162 includes a disc and a cross shaft. When assembled, the locking plate is clamped with the cross shaft of the lock head through its cross hole. The locking assembly is installed in the top plate, and the locking plate is placed in the circular hole of the secondary plate. The locking plate is driven to rotate around the axis through the cross shaft to lock or unlock with the tower head 3. The tower head 3 is coaxially arranged on the inner box 2.

[0049] like Figure 3 , Fig.13 As shown, the inner box 2 includes an inner box bottom plate 21, an opening and closing side plate 22, a closed side plate 23 and an inner box top plate 24. The inner box bottom plate 21 is a rectangular plate, with a positioning groove in the center, a hinge port on one edge, and positioning holes on the other three edges; the inner box bottom plate 21 is inserted into the positioning convex of the base with the positioning groove in the middle, and a hinge assembly is provided in the edge hinge port for assembling the opening and closing side plate 22, and the edge positioning hole is used to insert the closed side plate 23. The bottom end of the opening and closing side plate 22 is inserted into the hinge port and hinged with the hinge assembly, and a locking arm 25 is provided at the top, and a tenon is provided at the outer edge of the locking arm. Both ends of the closed side plate 23 are bosses, the bottom boss is inserted into the positioning groove on the inner box bottom plate, and the top boss is plugged into the inner box top plate. The top surfaces of the two closed side panels adjacent to the opening and closing side panels 22 are provided with slots for installing the locking plates 26. The middle part of the locking plates 26 is connected with a pair of ear plates by mortise and tenon. When assembling, the locking arm at the top of the opening and closing side panels extends between the two ear plates and is clamped with the ear plates by the latch plate 27 inserted into the mortise of the locking arm. When the opening and closing side panels need to be opened, the latch plate can be pulled out. The inner box top plate 24 is a rectangular plate, and its four sides are provided with positioning holes for plugging with the tops of the side panels. The middle part is connected with a tower head base plate through a pair of cross shafts for assembling the tower head 3.

[0050] like Fig.14 , Fig.15 As shown, the tower head 3 includes a tower head base plate 31, a lower pad 32, a cross central axis 33, a rotation limit plate 34, an upper pad 35 and a tower head panel 36. The rotation limit plate 34 is a circular plate, a through hole is provided at the center of the circle, four crescent-shaped notches are provided on the edge, and a circular arc protrusion 37 is provided on the entity between two adjacent notches. A lock hole is provided in the middle of the tower head panel 36. During assembly, the bottom section of the cross central axis passes through the lower pad to be clamped with the tower head base plate, the middle section is connected to the rotation limit plate, and the upper end passes through the upper pad to be clamped with the tower head panel; the rotation limit plate 34 can be driven to rotate by screwing a key into the lock hole, so that the circular arc protrusion on it slides relative to the clamping arm on the outer box.

[0051] like Fig.16 As shown, when the tower head and the outer box are assembled, the locking plate is pushed into the notch of the rotation limit plate to limit the rotation of the rotation limit plate; the clamping arm and the arc convex are fitted and locked to limit the rotation of the outer box side plate, so as to form a whole. Fig.17 As shown, when opening, the key inserted into the locking assembly drives the lock plate to rotate around the axis, contacting the restriction on the rotational freedom of the rotation limit plate, and then the key inserted into the tower head panel drives the rotation limit plate to rotate, so that the arc convexity is disengaged from the clamping arm, and the side panels of the outer box can be opened.

[0052] All parts of this embodiment are connected by mortise and tenon joints, and all boards are wooden boards, which are easy to carry. When put into use, a key to open the locking structure between the outer box and the tower head can be set on the outer box storage cabinet, and a three-dimensional greeting card can be set on the inner wall of each side panel. The greeting card is set with a plot or puzzle to give a hint of the next mechanism. Different from other paper desktop decryption games; this embodiment is a three-dimensional entity mechanism box with a certain plot story, which is different from the password box on the market; this box can be pushed by the plot, and various puzzles can be used to unlock the next mechanism to open each locking structure, add a social behavior model, and solve the monotony of the traditional password box. We have integrated the plot, enhanced the playability, and interesting elements. Compared with the escape room type game, through the use of this embodiment, the entire game process only needs to be carried out on the desktop, without any auxiliary tools; there is no location and space restriction, and it is easy to carry.
