Specifically, referring to fig. 9 and 10, the driving assembly 403 includes a first driving member 403a, a second driving member 403b, and a guide member 403 c. The first driving member 403a is a cylindrical structure, the opening and closing assembly 401 and the locking assembly 402 are both sleeved on an outer cylindrical wall of the first driving member 403a, and at least two protruding pieces 403a-1 (three pieces are exemplified in the present invention) are uniformly distributed on an outer side wall of the first driving member 403a along a circumference of a cross section, where the protruding pieces 403a-1 are protruding structural blocks on the outer cylindrical wall, and are used for performing embedded matching and driving on the opening and closing assembly 401 or the locking assembly 402. Further, the first driving member 403a has a sliding passage 403a-2 for inserting the guide 403c at a central axis position inside.

The second driving member 403b is externally connected to the outer end surface of the first driving member 403a, and the second driving member 403b can be fixed to the end of the first driving member 403a by a triangular bracket. The second driving member 403b is a shaft-like structure, and has a hollow limiting channel 403b-1 therein, and the opening of the channel is opposite to the sliding channel 403a-2 of the guiding member 403c, and the two are coaxial. The inner end of the guiding element 403c is fixed, the outer end passes through the sliding channel 403a-2 and is inserted into the limiting channel 403b-1, and it should be noted here that: a certain distance is reserved between the outer end of the guide 403c and the inner end of the spacing channel 403b-1, so that the whole combination of the first driving piece 403a and the second driving piece 403b can perform a certain degree of telescopic sliding on the guide 403c, and the limit value of the slidable length is the maximum distance between the outer end of the guide 403c and the inner end of the spacing channel 403 b-1.

The guide 403c is a fixed shaft that provides telescopic sliding and rotational driving of the driving assembly 403. The structure of the device can be correspondingly changed in diameter in order to adapt to the inner diameter of the sliding channel 403a-2 and the limiting channel 403 b-1. In the present invention, an end cap 403d is further disposed on the inner side of the locking assembly 402, the inner end of the guiding member 403c is fixed on the end cap 403d, and the outer end passes through the first driving member 403a and is inserted into the limiting channel 403b-1 of the second driving member 403 b. Further, the outer end of the second driving member 403b passes through the second locking portion 400, and a rotation knob 403b-2 is fixed at the end thereof for manual rotation or pressing to control the driving and telescopic action of the first driving member 403 a.

Referring to fig. 11 to 13, the opening/closing unit 401 can temporarily lock/unlock the top cover 102. In the present invention, the opening and closing assembly 401 includes a second guiding element 401a, a transmission element 401b and a first barb 401c, wherein the second guiding element 401a is a vertically disposed hollow guiding rail, and the lower end thereof is sleeved (clearance-fitted) on the outer side wall of the first driving element 403a through a spacing ring 401 a-1. The spacer 401a-1 is an annular body fixed to the lower end of the second guide member 401a, and the upper portion of the spacer 401a-1 is interrupted by an opening a which allows the protrusion 403a-1 of the first driving member 403a to pass through without hindrance.

The second guide 401a is provided inside with a guide block 401a-2, and the guide block 401a-2 can slide up and down in the vertical direction. The lower end of the guide block 401a-2 is further provided with a first elastic member 401a-3, the lower end of the first elastic member 401a-3 abuts against the bottom of the guide rail of the second guide member 401a, and the upper end abuts against the bottom of the guide block 401 a-2. The first elastic member 401a-3 is a spring, and the top of the strip-shaped body of the guide block 401a-2 is also fixed with a magnetic member 401 a-5.

The transmission member 401b includes a first rotating ring 401b-1 sleeved on an outer sidewall of the first driving member 403a, and a connecting rod 401b-2 hinged to the first rotating ring 401b-1, wherein an inner sidewall of the first rotating ring 401b-1 has a first notch 401b-3 engaged with the protruding member 403 a-1. Wherein, the first rotating ring 401b-1 can be arranged in a cam shape, the convex end of the first rotating ring is connected with the lower end of the connecting rod 401b-2 to form transmission, and the upper end of the connecting rod 401b-2 is hinged with the guide block 401a-2 through the allowable slot 401a-4 (vertical slot) on the second guide element 401 a. Therefore, as can be seen from the above description, when the protruding part 403a-1 of the first driving part 403a is inserted into the first notch 401b-3, the first rotating ring 401b-1 can be driven to rotate by rotating the first driving part 403a, and the first rotating ring 401b-1 can pull the guide block 401a-2 to slide downward in the second guide part 401a through the transmission of the connecting rod 401 b-2.

The first barb 401c is disposed on one side of the second guide 401a through the first limiting frame 401d, wherein the first barb 401c is a long strip-shaped hook-shaped structure, and the hook head of the first barb 401c is located at the upper end of the first barb 401c and can be matched with the connecting component 301; the first limiting frame 401d is used for mounting the first barb 401c and limiting the rotation amplitude of the first barb 401 c. A middle section of the first barb 401c is hinged to the first stopper 401d, and the first barb 401c is divided into a first region 401c-1 at the upper end and a second region 401c-2 at the lower end by a hinge node (where the first region 401c-1 and the second region 401c-2 are both made of a magnetically attractable material such as iron or iron-nickel alloy).

The top of the guide block 401a-2 is provided with a magnetic member 401a-5 corresponding to the first barb 401c, and the magnetic member 401a-5 can generate magnetic attraction (here, the magnetic member 401a-5 adopts a magnet) to the first region 401c-1 or the second region 401c-2, and cause the first barb 401c to rotate correspondingly, as follows:

since the guide block 401a-2 can move vertically up and down on one side of the first barb 401c, the magnetic member 401a-5 attracts the first barb 401c to rotate counterclockwise with respect to the first barb 401c when it is located at the position corresponding to the first region 401 c-1; when the first barb 401c is located at the position corresponding to the second zone 401c-2, the first barb 401c is attracted to rotate clockwise.

In the present invention, the initial state (temporarily locked state) of the opening/closing unit 401 is: the first rotating ring 401b-1 and the connecting rod 401b-2 are both vertical, and the magnetic member 401a-5 is located at the highest point and just corresponding to the first region 401c-1, so that the first barb 401c is attracted to a stable state and is engaged with the connecting component 301 to form a temporary lock.

The temporarily unlocked state of the opening and closing assembly 401 is: the rotating handle 403b-2 is operated to drive the first driving piece 403a to rotate, so that linkage can be generated, the guide block 401a-2 is pulled to slide downwards, until the magnetic piece 401a-5 slides to the position corresponding to the second area 401c-2, the first barb 401c rotates clockwise, the hook head is separated from the connecting component 301, and temporary unlocking is formed. At this time, when the rotation knob 403b-2 is released, the guide block 401a-2 returns to the original state by the resilient force of the first elastic member 401a-3, and remains in the temporarily locked state.

Therefore, summarizing the above two implementation processes, it can be seen that the locking and unlocking process can be implemented only by twisting the rotating handle 403 b-2. Preferably, since the outer edges of the hook heads of the connecting component 301 and the first barbs 401c are smooth curved surfaces, when the top cover 102 is turned over and fastened to the box casing 101, the connecting component 301 can be smoothly fastened down along the top curved surface of the first barbs 401c and form a lock with the top curved surface.

Referring to fig. 9, 13-17, the locking assembly 402 can lock the top cover 102 for an extended period of time. In the present invention, the locking assembly 402 includes a second rotating ring 402a sleeved on the outer sidewall of the first driving member 403a, a second inverted hook 402b fixed on the second rotating ring 402a, and a limiting piece 402c embedded in the second rotating ring 402 a. The second rotating ring 402a has a structure similar to that of the first rotating ring 401b-1, the main body thereof is a ring-shaped structure, and the inner sidewall thereof has a second notch 402a-1 matching with the protruding member 403a-1, and the second notch 402a-1 has the same structural form as the first notch 401 b-3.

The second inverted hook 402b has a lower end fixed to the second rotating ring 402a and an upper end capable of engaging and locking with the first locking portion 300. Accordingly, the bottom surface of the first locking portion 300 has a locking channel 302 that fits the configuration, contour of the second barb 402 b. When the hook head at the upper end of the second barb 402b is inserted into the locking channel 302, the top cover 102 and the box casing 101 can be locked permanently.

A complementary limiting piece 402c is embedded in the ring of the second rotating ring 402a, and the limiting piece 402c is used for limiting the rotation of the second rotating ring 402a (and the second barb 402 b). The stopper piece 402c has a projection 402c-1 on the outer side thereof to be fitted into the second notch 402a-1, so that the stopper piece 402c is rotated or stopped in conformity with the second rotating ring 402a when it is positioned in the ring of the second rotating ring 402 a. In addition, a limit through hole 402c-2 (the main structure of the limit through hole 402c-2 is a through hole which is in clearance fit with the outer side wall of the guide 403c) is formed in the center of the limit piece 402c and is matched with the guide 403c, that is, the guide 403c passes through the limit through hole 402c-2 of the limit piece 402 c. Furthermore, the inner side wall of the limiting penetration hole 402c-2 is provided with a limiting strip 402c-3 along the longitudinal direction of the guide piece 403c, the limiting strip 402c-3 is a strip-shaped protrusion and is provided with a pair of mutually opposite limiting strips, and the guide piece 403c is provided with a limiting groove 403c-1 matched with the limiting strip 402 c-3. Therefore, after the stopper rib 402c-3 of the stopper piece 402c is fitted into the stopper groove 403c-1, it can be linearly slid in the longitudinal direction of the guide 403c, but cannot be relatively rotated. Since the stopper piece 402c is fitted into the ring of the second rotating ring 402a, the second rotating ring 402a cannot rotate.

In the present invention, it is noted that: in the initial state, the stopper piece 402c is integrally inserted into the ring of the second rotating ring 402a, and simultaneously, the inner end of the first driving member 403a is also inserted into the ring of the second rotating ring 402a, and the outer end surface of the stopper piece 402c contacts with the inner end surface of the first driving member 403a (both of which are located in the ring of the second rotating ring 402a), so that the stopper piece 402c can be extruded out of the ring of the second rotating ring 402a by pushing the first driving member 403a by external force. In addition, the inner side of the limiting piece 402c is further provided with a second elastic member 402d (the second elastic member 402d can be a spring), the second elastic member 402d is sleeved on the guiding member 403c and abuts against the inner side surface of the limiting piece 402c, so as to abut the limiting piece 402c against the ring of the second rotating ring 402a, and prevent the situation that the limiting piece 402c is extruded out of the ring by pushing the first driving member 403a unintentionally by external errors. Correspondingly, the inner side surface of the limiting piece 402c is further provided with a plurality of limiting blocks 402c-4, and the limiting blocks 402c-4 are uniformly distributed on the outer edge of the circumference of the limiting piece 402c and used for preventing the limiting piece 402c from being extruded in the opposite direction due to the elastic force of the second elastic piece 402 d.

As described above, the stopper piece 402c can only slide within the length of the stopper groove 403c-1, and the sliding range is limited to the inside of the second rotating ring 402 a. In the invention, the outer side surface of the second barb 402b is connected with the second limiting frame 402e through a third elastic member 402e-1 (the third elastic member 402e-1 can adopt a spring), wherein the second limiting frame 402e is used for installing the third elastic member 402e-1, one end of the third elastic member 402e-1 is fixed on the second limiting frame 402e, and the other end abuts against the outer side surface of the second barb 402b to form elastic potential energy.

Thus, to summarize, the initial state (unlocked state) of the locking component 402 is: the stopper 402c is located in the second rotating ring 402a, and the second rotating ring 402a cannot rotate, so the second barb 402b cannot be inserted into the locking channel 302 for locking. In this state, the above-described temporary locking and unlocking process can be achieved by simply twisting the rotating knob 403 b-2.

The deadlocked state of the locking assembly 402 is: the first driving member 403a is pushed (pushing force is greater than the elastic force of the second elastic member 402d), so that the inner end of the first driving member 403a pushes the stopper piece 402c out of the second rotating ring 402 a. Because there is no rotation restriction of the limiting piece 402c to the second rotating ring 402a (the limiting piece 402c cannot rotate all the time, but can only slide), the second barb 402b rotates clockwise along with the second rotating ring 402a under the elastic force of the third elastic member 402e-1 until the hook head of the second barb 402b is completely inserted into the locking channel 302, so as to form a locking.

The process of the locking component 402 removing the deadlocked state is: pushing the first driving member 403a inward until advancement is no longer possible, at which point the male member 403a-1 on the first driving member 403a is misaligned with the second notch 402a-1 of the second rotating ring 402a, thereby rotating the first driving member 403a until the male member 403a-1 is in spatial alignment with the second notch 402a-1 and advancing the embedment; then, the first driving member 403a is rotated reversely to drive the second rotating ring 402a to rotate reversely until the second notch 402a-1 of the second rotating ring 402a is aligned with the protrusion 402c-1 of the limiting piece 402c, and at this time, the limiting piece 402c pushes the limiting piece 402c into the ring of the second rotating ring 402a under the action of the second elastic member 402d, so as to restore to the initial state of the locking assembly 402, and the locked state is released.

Preferably, in the present invention, it is also possible to set: the second notch 402a-1 of the second rotating ring 402a is just aligned with the protruding part 403a-1 in the above-mentioned locking state (accordingly, the initial state of the second notch 402a-1 and the protrusion 402c-1 is a position rotated counterclockwise by a corresponding angle), and therefore, the procedure of releasing the locking state in this preferred case is as follows: the first driving member 403a is pushed to be embedded into the second rotating ring 402a, and then the second rotating ring rotates counterclockwise by a corresponding angle until the first driving member faces the limiting piece 402 c.

In the present invention, the second locking portion 400 further includes a lock housing 404, and the first limiting frame 401d and the second limiting frame 402c are fixed on an inner side wall of the lock housing 404. Additionally, the inner end of the guide 403c is secured to the end cap 403d, which in turn is secured to the inside surface of the lock body housing 404. The outer end of the second driving member 403b in the present invention extends through the lock body housing 404 and has a rotating handle 403b-2 secured to its end. In addition, the top of the lock body housing 404 is provided with a first through hole 404a corresponding to the connecting member 301 and a first through hole 404b corresponding to the second barb 402 b. The outer side of the lock body housing 404 is also covered with an outer cover 404c, and the periphery of the outer cover 404c is fixed to the edge of the lock body housing 404 by screws.
