[0044] The present invention is described in detail below.

[0045] like Figure 1-Figure 16 As shown:

[0046] An upwardly reversible and movable press-sealing structure comprises a box cover, and a box body 5 which is buckled with the box cover and sleeved on the outer side of the box cover;

[0048] Furthermore, the elastic buckle components 3 are two groups and are symmetrically arranged. The two groups of elastic buckle components 3 can realize the opening or locking of the box body 5 and the box cover under the drive of the retractable pressing component 4;

[0049] When the box cover and the box body 5 are locked, the retractable pressing component 4 abuts against the elastic buckle component 3 on the side close to the installation cavity 11, and the end of the elastic buckle component 3 away from the installation cavity 11 passes through the lower cover 2 and buckles with the box body 5.

[0050] In the initial state, the retractable pressing component 4 will be located above the upper cover 1. After the product is loaded into the box body 5, the box cover is installed on the box body 5, and a force is applied to the retractable pressing component 4 to move toward one side of the box body 5 so that the retractable pressing component 4 moves downward, thereby driving the rear elastic buckle component 3 to move along the X-axis direction, so that the end of the elastic buckle component 3 away from the retractable pressing component 4 passes through the box cover and buckles with the box body 5, and at the same time, the retractable pressing component 4 is locked; thereby, the box body 5 and the box cover are connected and fixed to form a whole;

[0051] When opening the box cover, the retractable pressing component 4 is pressed, and the retractable pressing component 4 moves away from the box body 5 after being subjected to the force, and the elastic buckle component 3 moves away from the box body 5 along the X-axis direction, shrinks in the box cover, and no longer buckles the box body 5 and the box cover, and the retractable pressing component 4 is no longer locked and moves away from the box body 5 along the Z-axis.

[0052] In some possible implementations, the retractable pressing assembly 4 includes a pressing cover 41 located in the installation cavity 11 and slidingly matched with the upper cover 1 along the Z-axis direction, and a rotating locking assembly 42 installed in the installation cavity 11 and used to lock the pressing cover 41;

[0053] When the pressing cover 41 is pressed downward, the lower edge of the pressing cover 41 abuts against the elastic buckle assembly 3, driving the elastic buckle assembly 3 to slide along the X-axis direction in the installation cavity 11 to lock or open the box body 5;

[0054] When locking, the rotating locking component 42 will rotate after the pressing cover 41 is subjected to force, and will be locked when the elastic buckling component 3 passes through the box cover and buckles with the box body 5.

[0055] In some possible embodiments, the rotation locking assembly 42 includes a Z-axis shaft 421 disposed on the pressing cover 41 and located in the installation cavity 11, a direction-changing column 422 sleeved on the outside of the Z-axis shaft 421 and rotatably matched with the Z-axis shaft 421, a direction-changing disc 423 installed in the upper cover 1 and sleeved on the outside of the direction-changing column 422, and a spring 424 sleeved on the outside of the direction-changing disc 423; the direction-changing disc 423 and the direction-changing column 422 slide in the Z-axis direction to achieve telescopic movement along the pressing cover 41 in the Z-axis direction; the Z-axis shaft 421, the upper cover 1, the lower cover 2, and the box body 5 are coaxially arranged; the Z-axis shaft 421 is arranged along the Z-axis direction;

[0056] The direction-changing column 422 is sleeved on the outer side of the Z-axis 421 and the two are rotatably matched. A limit screw 425 is installed at the bottom of the Z-axis 421. The direction-changing column 422 and the Z-axis 421 are formed into an integral structure through the limit screw 425 and the two are rotatably matched.

[0057] In some possible implementations, multiple groups of guide portions 4221 are disposed on the outer side of the direction-changing column 422 and along its circumference, and multiple groups of ratchet teeth 4222 are disposed on a side of the direction-changing column 422 close to the pressing cover 41 ;

[0058] A gap is formed between the bottom of the guide portion 4221 and the bottom of the ratchet tooth 4222 for the hanging tooth 4233 to pass through;

[0059] A guide groove is formed between two adjacent groups of guide portions 4221, and a V-shaped locking groove 42211 is provided on one side of the guide portion 4221 close to the ratchet tooth 4222. The guide groove includes a slide groove 4223 arranged in the Z-axis direction, and a V-shaped groove 4224 respectively connected to both ends of the slide groove 4223, and the small end of the V-shaped groove 4224 is connected to the end of the slide groove 4223; the opening of the locking groove 42211 is upward, and the large end has an opening.

[0060] In some possible embodiments, the steering disc 423 includes a sleeve 4231 that is sleeved on the outside of the steering column 422 and cooperates with the steering column 422, and a support disc 4232 that is sleeved on the outside of the sleeve 4231; a hanging tooth 4233 that cooperates with the slide groove 4223 is arranged in the sleeve 4231; an end of the sleeve 4231 away from the pressing cover 41 passes through the installation cavity 11 and is buckled and connected to the bottom of the upper cover 1; the hanging tooth 4233 is arranged There are a locking surface 42331 that cooperates with the bottom of the locking groove 42211 and realizes the locking and fixing of the pressing cover 41 and the upper cover 1, a direction-changing surface 42332 that cooperates with the bottom surface of the ratchet 4222, and a guide surface 42333 that cooperates with the bottom surface of the V-shaped groove 4224; the direction-changing surface 42332 is an inclined surface and is consistent with the inclination direction of the bottom surface of the ratchet 4222, and the guide surface 42333 is also an inclined surface and is consistent with the inclination direction of the bottom surface of the V-shaped groove 4224;

[0061] Furthermore, the inclination directions of the direction-changing surface 42332, the bottom surface of the ratchet tooth 4222, and the guide surface 42333 are consistent;

[0062] The steering disc 423 is installed in the installation cavity 11 of the upper cover 1, and the hanging teeth 4233 in the steering disc 423 are slidably matched with the sliding groove 4223 outside the steering column 422, and the sliding groove 4223 is arranged along the Z-axis direction, so that the pressing cover 41 can be extended and retracted along the Z-axis direction;

[0063] When the box body 5 is buckled with the box cover, the pressing cover 41 is forced to move downward, driving the direction-changing column 422 to move downward, and then the hanging tooth 4233 passes through the V-shaped groove 4224 above the slide groove 4223 and is located in the gap formed between the guide portion 4221 and the ratchet tooth 4222. At this time, the direction-changing column 422 is no longer limited by the hanging tooth 4233. Since the direction-changing column 422 is continuously subjected to the downward force, the bottom surface of the ratchet tooth 4222 will abut against the top surface of the hanging tooth 4233, both of which are inclined surfaces, so that the direction-changing column 422 rotates, and then the hanging tooth 4233 will pass through the guide portion The gap between 4221 and the ratchet tooth 4222 enters the locking groove 42211, and the locking surface 42331 of the hanging tooth 4233 contacts and cooperates with the bottom surface of the locking groove 42211, thereby limiting the continuous rotation of the direction-changing column 422; during the rotation of the direction-changing column 422, the pressing cover 41 moves downward to exert an action on the elastic buckle component 3 to move toward the side away from the installation cavity 11, so that the end of the elastic buckle component 3 will pass through the box cover and enter the box body 5, and when the locking surface 42331 of the hanging tooth 4233 contacts and cooperates with the bottom surface of the locking groove 42211, the box body 5 and the box cover are buckled.

[0064] On the contrary, when the box body 5 and the box cover are opened, the pressing cover 41 is pressed, and the pressing cover 41 is forced to move downward, the bottom surface of the locking groove 42211 is separated from the locking surface 42331, and the direction-changing column 422 can be rotated, and through the cooperation of the direction-changing surface 42332, the bottom surface of the V-shaped groove 4224, and the bottom surface of the ratchet 4222, the direction-changing column 422 makes the hanging tooth 4233 enter the corresponding sliding groove 4223 after the direction-changing rotation, the pressing cover 41 will move upward at this time, driving the direction-changing column 422 to move to the side away from the box body 5, and the pressing cover 41 will no longer apply a force to the elastic buckle assembly 3; the elastic buckle assembly 3 moves along the X-axis direction and is retracted into the box cover, so that the box body 5 and the box cover are separated;

[0065] The upper cover 1 is provided with a hole for the sleeve 4231 to pass through, and the bottom of the sleeve 4231 is provided with buckles to achieve a buckling connection with the upper cover 1; a circular ring portion coaxial with the hole is provided on the upper cover 1 and located in the installation cavity 11, and the circular ring portion is sleeved on the outer side of the circular support plate 4232; a spring 424 is located between the sleeve 4231 and the circular ring portion; the spring 424 is in a compressed state when the box cover and the box body 5 are buckled together, and when opening, the spring 424 will return to the initial state, push the pressing cover 41 upward, so that the pressing cover 41 is separated from the elastic buckling component 3, and the elastic buckling component 3 will return to the initial state from the compressed state after being free of force, so that the box body 5 and the box cover are opened;

[0066] In some possible embodiments, the elastic buckle assembly 3 includes a sliding frame 31 installed in the chamber and having one end extending into the installation cavity 11, a buckle portion 32 rotatably installed on the sliding frame 31 and having one end passing through the lower cover 2 and buckled with the box body 5, and an elastic assembly 33 installed on the sliding frame 31 and arranged on the side of the sliding frame 31 away from the installation cavity 11; the side of the sliding frame 31 close to the installation cavity 11 is a sliding surface 311 used in conjunction with the lower edge of the pressing cover 41, and the sliding surface 311 is an inclined surface, and the angle formed in the Z-axis direction is an acute angle;

[0067] The sliding frame 31 includes a base slidably mounted in the mounting cavity, two sets of brackets mounted on the base and symmetrically arranged; the buckle portion 32 is located between the two sets of brackets and cooperates with the two sets of brackets to rotate around the Y axis direction; the elastic component 33 is arranged on the side of the bottom away from the mounting cavity 11;

[0068] The elastic component 33 includes a positioning shaft 331 arranged on the side of the sliding frame 31 away from the installation cavity 11 and arranged along the X-axis direction, and a spring 2 332 which is sleeved on the outside of the positioning shaft 331 and connected to the sliding frame 31; when the sliding frame 31 is acted upon by the pressing cover 41, it will move along the X-axis direction toward the side away from the installation cavity 11, and the spring 2 332 will change from an initial state to a compressed state.

[0069] In some possible implementations, the buckle portion 32 includes a rotating shaft 321 arranged along the Y-axis direction and rotatingly matched with the sliding frame 31 around the Y-axis direction, and a buckle block sleeved on the rotating shaft 321; a through hole 20 is arranged on the lower cover 2 and is installed at one end of the buckle block away from the installation cavity 11, and a buckle hole 50 is arranged on the inner side surface of the box body 5 and is arranged corresponding to the through hole 20;

[0070] Preferably, the buckle blocks are in two groups, and the through holes 20 and the buckle holes 50 are arranged correspondingly;

[0071] The buckle block includes a support block 322 having a buckle tooth 3221 at one end and connected to the rotating shaft 321 at the other end, and a driving block 323 connected to the rotating shaft 321 and arranged on a side of the rotating shaft 321 close to the installation cavity 11; the support block 322 and the driving block 323 are in a Z-shaped structure, wherein the buckle tooth 3221 on the support block 322 is arranged on a side close to the pressing cover 41, and the driving block 323 is arranged on a side close to the lower cover 2;

[0072] When the pressing cover 41 is subjected to force, its lower edge moves downward after being subjected to force, and contacts the sliding surface 311, so that the sliding frame 31 and the buckling block move toward the side close to the buckling hole 50 along the X-axis direction. Then, the lower edge of the pressing cover 41 contacts the driving block 323 and applies a downward force to the driving block 323, so that the driving block 323 rotates downward around the Y-axis direction, thereby driving the supporting block 322 to rotate upward around the Y-axis direction and buckle with the buckling hole 50.

[0073] Furthermore, the sliding frame 31 is also provided with a tooth surface 312 near the installation cavity 11. The angle formed by the tooth surface 312 and the Z-axis direction is smaller than the angle formed by the sliding surface 311 and the Z-axis direction. When the buckling teeth 3221 cooperate with the buckling holes 50 to realize the box body 5 and the box cover, the lower edge of the pressing cover 41 will contact and abut against the tooth surface 312. When the pressing cover 41 continues to move downward, the tooth surface 312 will contact with the lower edge of the pressing cover 41.

[0074] Specifically, the side of the driving block 323 away from the rotating shaft 321 is also an inclined surface, and its distance from the installation cavity 11 is smaller than the distance between the sliding surface 311 and the installation cavity 11. When the pressing cover 41 moves downward, the lower edge of the pressing cover 41 will contact the tooth surface 312. Since the pressing cover 41 will also move downward, it will generate vibration and sound with the tooth surface 312, thereby increasing the user's experience. When the pressing reaches the downward end position, positioning is achieved.

[0075] On the contrary, when opening, the pressing cover 41 is pressed again, the rotating locking assembly 42 is no longer locked, the pressing cover 41 moves to the side away from the box body 5, the elastic buckle assembly 3 is no longer stressed, the second spring 332 will recover from the compressed state to the initial state, the sliding frame 31 and the buckle block will move to the side close to the installation cavity 11, and the buckling teeth 3221 on the support block 322 will shrink into the through hole 20, so that the box cover and the box body 5 are separated;

[0076] Furthermore, the pressing cover 1 includes a top plate, and an annular side plate connected to the top plate and located at the bottom of the top plate. The chamber formed by the upper cover 1 and the lower cover 2 is an annular structure. The sliding frame is located in the chamber and one end passes through the chamber and is located in the installation chamber 11, so as to cooperate with the annular side plate and drive the elastic buckle assembly 3 to realize the buckling of the box cover and the box body 5.

[0077] A snap-fitting tooth 1 is provided at the bottom of the pressing cover 41, and the snap-fitting tooth 1 is provided at the bottom of the annular side plate. A snap-fitting hole 12 used in conjunction with the snap-fitting tooth 1 is provided on the upper cover 1. The snap-fitting tooth 1 is located in the snap-fitting hole 12. When the pressing cover 41 moves upward along the Z-axis direction, the snap-fitting tooth 1 will snap into contact with the top surface of the snap-fitting hole 12, so that the pressing cover 41 will not be separated from the upper cover 1.
