[0030] Please see the appendix Figure 1 - Appendix Figure 10 Specific Implementation Example 1:

[0032] A press-type packaging box includes a box body, a locking mechanism 3, and an elastic element 4.

[0033] like Figures 1-2 As shown, the box body includes an outer box 1 and an inner box 2. The outer box 1 is a cylindrical structure with an opening at the top. The inner box 2 is a hollow box that fits into the inner cavity of the outer box 1 and can be used to place goods inside. The inner box 2 is movably disposed within the inner cavity of the outer box 1 and can move freely up and down. The inner box 2 has an opening at the top and is provided with a removable lid 201. The upper outer periphery of the inner box 2 has an inwardly recessed ring, and the inner wall of the lid 201 can fit and engage with the upper outer periphery of the inner box 2.

[0034] The elastic element 4 is a support spring. The support spring is located between the bottom inside the outer box 1 and the bottom outside the inner box 2. When there is no external force, it can support and lift the inner box 2 containing the goods, so that the upper part of the inner box 2 extends out of the upper opening of the outer box 1, so as to facilitate the removal of the box cover 201.

[0035] like Figures 3-6 As shown, the locking mechanism 3 is located between the inner bottom wall of the outer box 1 and the outer bottom wall of the inner box 2, at the center of the inner cavity of the outer box 1, and specifically includes a locking head 301, a locking connector 302 and an unlocking buckle 303.

[0036] The bottom center of the outer box 1 has a stepped hole. The lower part of the locking head 301 has a horizontally extending base that fits and is fixed to the stepped hole at the bottom of the outer box 1. The center of the base extends upward to form a slender column. The snap-fit ​​plate 3011 is a frustum-shaped part with a central hole. The snap-fit ​​plate 3011 is fixedly connected to the upper end of the column of the locking head 301 through the central hole. An inclined chamfer is made at the upper edge of the snap-fit ​​plate 3011, so that the snap-fit ​​plate 3011 is a frustum-shaped body that is smaller at the top and larger at the bottom.

[0037] The unlocking buckle 303 is a ring-shaped part with a through hole at its center, the diameter of which matches the diameter of the locking head 301. The unlocking buckle 303 passes through the locking head 301 and can slide freely along the axis of the head. The end of the unlocking buckle 303 furthest from the retaining plate 3011 gradually widens towards the end closer to the retaining plate 3011. The outer edge contour of the largest end of the unlocking buckle 303 is greater than or equal to the outer edge contour of the largest end of the retaining plate 3011, and the outer edge contour of the smallest end of the unlocking buckle 303 is less than or equal to the outer edge contour of the smallest end of the retaining plate 3011.

[0038] The bottom center of the inner box 2 has a stepped hole. A horizontally extending platform is formed on the upper part of the snap-fit ​​connector 302 and is fitted and fixed in the stepped hole. Below the platform, six snap-fit ​​claws 3021 are arranged at intervals along the central axis. The lower end of each snap-fit ​​claw 3021 has an inwardly pointing barb 3022. The outer edge of the barb 3022 has a gradually expanding, inclined surface from the bottom end towards the platform. The distance from the maximum end of the barb 3022 to the central axis is less than the distance from the maximum end of the snap-fit ​​plate 3011 to the central axis, while the distance from the minimum end of the barb 3022 to the central axis is greater than the distance from the maximum end of the unlocking buckle 303 to the central axis. The vertical height between the maximum and minimum ends of the barb 3022 is less than the thickness of the unlocking buckle 303. The snap-fit ​​connector 302 is positioned above the central axis of the locking head 301, with the snap-fit ​​claws 3021 facing the snap-fit ​​plate 3011.

[0039] The principle of fastening and unlocking:

[0040] When fastened, as Figure 3 As shown, the unlocking buckle 303, under the action of gravity, adheres to the upper side of the base of the locking head 301. Pressing down on the inner box 2 causes it to move downward against the elastic force of the support spring. The locking connector 302 is driven to move downward together. During the descent, the barb 3022 gradually abuts against the chamfered end of the locking plate 3011. The smallest end of the chamfer of the locking plate 3011 extends into the space enclosed by the six barbs 3022. As the descent continues, the locking plate 3011 can expand the locking claw 3021 and extend into the space enclosed by the upper part of the barb 3022 of the locking claw 3021. At this time, the force of pressing the inner box 2 is removed. The inner box 2 moves upward under the elastic force of the support spring and simultaneously drives the locking connector 302 to move upward together, realizing the abutment and engagement between the largest end of the barb 3022 and the largest end of the locking plate 3011. When the lid is closed, the upper surface of the lid 201 is flush with the edge of the opening above the outer box 1, so that the inner box 2 is stored in the outer box 1.

[0041] When unlocking, the inner box 2 is pressed downward to overcome the elastic force of the supporting spring, and the clamping head 302 is simultaneously driven to move downward. During the downward movement, the barbs 3022 gradually abut against the unlocking buckle 303, and the maximum end of the unlocking buckle 303 can extend into the space surrounded by the six barbs 3022. With the continuous downward movement, the unlocking buckle 303 can expand the clamping jaw 3021, and the whole extends into the space surrounded by the upper part of the clamping jaw 3021 and the barbs 3022. At this time, the force pressing the inner box 2 is removed, the inner box 2 moves upward under the elastic force of the supporting spring and simultaneously drives the clamping head 302 to displace upward. As shown in Figure 4 the unlocking ring 303 is simultaneously driven to translate upward and abut against the clamping disc 3011. At this time, the minimum end of the unlocking ring 303 can extend into the space surrounded by the six barbs 3022, the clamping jaw 3021 continues to move upward under the expansion elastic force of the supporting spring, the maximum end of the barbs 3022 abuts against the gradually expanding outer edge of the unlocking buckle 303 to relatively slide, and the clamping jaw 3021 is deformed outwardly and then translates upward to pass over the maximum end of the outer edge of the clamping disc 3011, so as to realize the uncoupling of the clamping head 302 and the locking head 301.

[0042] Specific embodiment two: on the basis of the specific embodiment one, as shown in Figures 7-10 another specific structure of the locking mechanism 3 is provided, the locking mechanism 3 is arranged between the inner bottom wall of the outer box 1 and the outer bottom wall of the inner box 2 and is located at the inner cavity axis of the outer box 1, and specifically includes the locking head 301, the clamping head 302 and the unlocking buckle 303.

[0043] The bottom center of the outer box 1 is provided with a stepped hole, the lower part of the locking head 301 is provided with a horizontally extending base and is embedded and fixed in the stepped hole of the bottom of the outer box 1, the upper side of the base extends upward to form a ring-shaped vertical wall, and the upper end of the vertical wall is provided with a ring-shaped clamping disc 3011 which extends radially inward.

[0044] The unlocking buckle 303 is a circular ring-shaped part and is movably arranged on the inner side of the ring-shaped vertical wall of the locking head 301 and can freely slide along the central axis direction of the locking head 301. The inner ring diameter of the unlocking buckle 303 is less than or equal to the inner ring diameter of the ring-shaped clamping disc 3011. In addition, the inner ring of the unlocking buckle 303 is provided with an inclined chamfer near the inner ring of the base of the locking head 301, and the inner ring of the unlocking buckle 303 forms an inclined taper hole structure which gradually narrows upward from the bottom.

[0045] The bottom center of the inner box 2 is provided with a stepped hole, the upper part of the clamping head 302 is provided with a horizontally extending platform and is embedded and fixed in the stepped hole, six clamping claws 3021 are arranged on the lower part of the platform along the central axis and are rotationally spaced, the lower end of the clamping claw 3021 is outwardly provided with a barb 3022 facing away from the shaft center, the outer edge of the barb 3022 is provided with a slope from the bottom end to the side of the platform, and the structure is gradually inclined and enlarged. The distance from the maximum end of the barb 3022 to the central axis is greater than the distance from the inner side of the clamping disc 3011 to the central axis and is less than the distance from the bottom of the inner ring chamfer of the unlocking buckle 303 to the central axis. The vertical height of the maximum end of the barb 3022 from the minimum end is less than the vertical height of the chamfer of the unlocking buckle 303. The clamping head 302 is arranged above the central axis of the locking head 301, and the clamping claw 3021 faces the side of the clamping disc 3011.

[0046] Buckling and unlocking principles:

[0047] When buckling, as shown in Figure 7 , the unlocking buckle 303 is attached to the upper side of the base of the locking head 301 under the action of gravity, the inner box 2 is pressed downward to overcome the elastic force of the supporting spring, and the clamping head 302 is driven to move downward together. During the downward movement, the barb 3022 gradually abuts against the inner ring of the clamping disc 3011, the minimum end of the barb 3011 can extend into the inner ring of the clamping disc 3011, and the clamping claw 3021 can be deformed and folded by the clamping disc 3011, and the barb 3022 enters the annular vertical wall inner cavity of the locking head 301. At this time, the force pressing the inner box 2 is removed, the inner box 2 moves upward under the elastic force of the supporting spring and simultaneously drives the clamping head 302 to displace upward, so that the barb 3022 and the clamping disc 3011 are buckled. In the buckled state, the upper surface of the box cover 201 is flush with the edge of the upper opening of the outer box 1, so that the inner box 2 is accommodated in the outer box 1.

[0048] When unlocking, the inner box 2 is pressed downward to overcome the elastic force of the supporting spring, and the clamping head 302 is simultaneously driven to move downward. During the downward movement, when the barb 3022 gradually abuts against the unlocking buckle 303, the minimum end of the barb 3022 can extend into the annular inner side of the unlocking buckle 303, and the unlocking buckle 303 can deform and fold the clamping claw 3021, and the barb 3022 extends into the inclined tapered hole structure formed by the chamfer of the unlocking buckle 303. At this time, the force pressing the inner box 2 is removed, the inner box 2 moves upward under the elastic force of the supporting spring and simultaneously drives the clamping head 302 to displace upward. As shown in Figure 8As shown, the barb 3022 is brought along to translate upward due to being located in the inclined taper hole structure of the unlocking buckle 303 until abutting against the clamping disc 3011, at this time, the maximum end of the barb 3022 abuts against the chamfered slope of the unlocking buckle 303, the clamping claw 3021 continues to move upward under the opening elastic force of the supporting spring, the maximum end of the barb 3022 abutting against the chamfered slope gradually reducing of the unlocking buckle 303 does relative sliding, the clamping claw 3021 does corresponding folding deformation and then translates upward to pass the inner ring wall of the clamping disc 3011, thereby realizing the unlocking of the clamping head 302 and the locking head 301.

[0049] The above merely describes the preferred embodiments of the present application and is not intended to limit the purpose, any modification, replacement or variation within the principle of the present application is within the protection scope of the present application.
