The second guide 501a is provided inside with a guide block 501a-2, and the guide block 501a-2 can slide up and down in the vertical direction. The lower end of the guide block 501a-2 is further provided with a first elastic piece 501a-3, the lower end of the first elastic piece 501a-3 is abutted against the bottom of the guide rail of the second guide piece 501a, and the upper end is abutted against the bottom of the guide block 501 a-2. The first elastic member 501a-3 here adopts a spring, and the bar-shaped body of the guide block 501a-2 is also fixed with the magnetic member 501a-5 at the top.
The transmission part 501b comprises a first rotating ring 501b-1 sleeved on the outer side wall of the first driving part 503a and a connecting rod 501b-2 hinged with the first rotating ring 501b-1, and a first notch 501b-3 matched with the outer convex part 503a-1 is formed on the inner side wall of the first rotating ring 501 b-1. Wherein the first rotating ring 501b-1 may be provided in a cam shape, the convex end of which is connected with the lower end of the connecting rod 501b-2 to form a transmission, and the upper end of the connecting rod 501b-2 is hinged with the guide block 501a-2 through the allowable slot 501a-4 (vertical slot) on the second guide 501 a. Therefore, as shown above, if the protruding part 503a-1 of the first driving part 503a is embedded into the first notch 501b-3, the first rotating ring 501b-1 can be driven to rotate simultaneously by rotating the first driving part 503a, and the first rotating ring 501b-1 can pull the guiding block 501a-2 to slide downward in the second guiding part 501a through the transmission of the connecting rod 501 b-2.
The first barb 501c is disposed on one side of the second guide member 501a through the first limiting frame 501d, where the first barb 501c is in a strip-shaped hook structure, and a hook head of the hook is located at the upper end of the first barb 501c and can be matched with the connection component 401; the first limiting frame 501d is used for mounting the first barb 501c and limiting the rotation range of the first barb 501 c. A certain middle section of the first barb 501c is hinged with the first limiting frame 501d, and the first barb 501c is divided into a first area 501c-1 at the upper end and a second area 501c-2 at the lower end by a hinge joint (the first area 501c-1 and the second area 501c-2 are made of materials which can be attracted magnetically, such as iron or iron-nickel alloy).
The top of the guide block 501a-2 is provided with a magnetic member 501a-5 corresponding to the first barb 501c, and the magnetic member 501a-5 can magnetically attract the first region 501c-1 or the second region 501c-2 (the magnetic member 501a-5 here adopts a magnet), and make the first barb 501c rotate correspondingly, as follows:
since the guide block 501a-2 can vertically move up and down on one side of the first barb 501c, the magnetic member 501a-5 attracts the first barb 501c to rotate counterclockwise relative to the first barb 501c when it is located at the position corresponding to the first region 501 c-1; when it is located at the position corresponding to the second region 501c-2, the first barb 501c is attracted to rotate clockwise.
In the present application, due to the elastic action of the first elastic member 501a-3 on the guide block 501a-2, the initial state (temporary locking state) of the opening and closing assembly 501 is: the first rotating ring 501b-1 and the connecting rod 501b-2 are vertical, and the magnetic member 501a-5 is located at the highest point and corresponds exactly to the first region 501c-1, so that the first barb 501c is attracted to a stable state and engages with the connecting assembly 401 to form a temporary lock.
The temporary unlocked state of the shutter assembly 501 is: by operating the rotating handle 503b-2 to drive the first driving member 503a to rotate, linkage can be generated, and the guiding block 501a-2 is pulled to slide downwards until the magnetic member 501a-5 slides to the position corresponding to the second region 501c-2, the first barb 501c rotates clockwise, and the hook head is separated from the connecting assembly 401, so as to form temporary unlocking. At this time, when the rotating handle 503b-2 is released, the guide block 501a-2 is restored to the original state by the resilient force of the first resilient member 501a-3, and still becomes a temporarily locked state.
Therefore, it can be seen from a summary of the implementation processes of the two states that the locking and unlocking processes during temporary operation can be implemented by merely twisting the rotary handle 503b-2. Preferably, since the outer edges of the hook heads of the connecting component 401 and the first barb 501c are smooth curved surfaces, when the insect prevention window 302 is turned over and buckled on the first fixing window 202, the connecting component 401 can smoothly buckle down along the curved surface of the top of the first barb 501c and form locking with the hook heads.
Referring to fig. 9 and 13-17, the locking assembly 502 is capable of locking the insect control window 302 for a long period of time. In the present application, the locking assembly 502 includes a second rotating ring 502a sleeved on the outer sidewall of the first driving member 503a, a second barb 502b fixed on the second rotating ring 502a, and a limiting piece 502c embedded in the second rotating ring 502 a. The second rotating ring 502a has a similar structure to the first rotating ring 501b-1, and has a ring-shaped main body, and a second notch 502a-1 matching with the outer protrusion 503a-1 on the inner side wall, and the second notch 502a-1 has the same structure as the first notch 501b-3.
The second barb 502b has a lower end fixed to the second rotating ring 502a and an upper end capable of being engaged with the first locking part 400. Correspondingly, the bottom surface of the first locking portion 400 has a locking channel 402 that matches the structure and contour of the second barb 502 b. When the hook head at the upper end of the second barb 502b is embedded in the locking channel 402, the insect-proof window 302 and the first fixing window 202 can be permanently locked.
A complementary limiting piece 502c is embedded in the ring of the second rotating ring 502a, and the limiting piece 502c is used for limiting the rotation of the second rotating ring 502a (and the second barb 502 b). The outside of the limit tab 502c has a protrusion 502c-1 that mates with the second notch 502a-1 so that when the limit tab 502c is positioned within the ring of the second rotating ring 502a, its rotated or resting state is consistent with the second rotating ring 502 a. In addition, the center of the limiting piece 502c is penetrated with a limiting through hole 502c-2 (the main structure of the limiting through hole 502c-2 is a through hole in clearance fit with the outer side wall of the guiding piece 503 c), that is, the guiding piece 503c penetrates through the limiting through hole 502c-2 of the limiting piece 502c. Further, the inner sidewall of the limiting through hole 502c-2 is provided with a limiting bar 502c-3 along the longitudinal direction of the guiding member 503c, the limiting bar 502c-3 is a bar-shaped protrusion and has a pair of opposite sides, and the guiding member 503c is provided with a limiting groove 503c-1 matching with the limiting bar 502 c-3. Therefore, after the stopper piece 502c-3 of the stopper piece 502c is inserted into the stopper groove 503c-1, it is possible to linearly slide along the longitudinal direction of the guide 503c, but it is impossible to relatively rotate. Since the stopper piece 502c is embedded in the ring of the second rotating ring 502a, the second rotating ring 502a cannot rotate either.
In the present application, it is noted that: in the initial state, the limiting piece 502c is integrally embedded into the ring of the second rotating ring 502a, meanwhile, the inner end of the first driving piece 503a is also embedded into the ring of the second rotating ring 502a, and the outer end surface of the limiting piece 502c is contacted with the inner end surface of the first driving piece 503a (both are positioned in the ring of the second rotating ring 502 a), so that the limiting piece 502c can be extruded out of the ring of the second rotating ring 502a by pushing the first driving piece 503a through external force. In addition, a second elastic piece 502d (the second elastic piece 502d may be a spring) is further disposed on the inner side of the limiting piece 502c, and the second elastic piece 502d is sleeved on the guide piece 503c and abuts against the inner side surface of the limiting piece 502c, so as to abut the limiting piece 502c against the ring of the second rotating ring 502a, and prevent the situation that the first driving piece 503a is unintentionally pushed by an external error, so that the limiting piece 502c is extruded out of the ring. Correspondingly, the inner side surface of the limiting piece 502c is further provided with a plurality of limiting pieces 502c-4, and the limiting pieces 502c-4 can be uniformly distributed on the peripheral outer edge of the limiting piece 502c and used for preventing the limiting piece 502c from being extruded in the opposite direction due to the elastic force of the second elastic piece 502 d.
As can be seen from the above, the limiting piece 502c can only slide within the length range of the limiting groove 503c-1, and the sliding range is limited to the second rotating ring 502 a. In the present application, the outer side surface of the second barb 502b is connected to the second limiting frame 502e through the third elastic member 502e-1 (the third elastic member 502e-1 may use a spring), wherein the second limiting frame 502e is used for installing the third elastic member 502e-1, one end of the third elastic member 502e-1 is fixed on the second limiting frame 502e, and the other end abuts against the outer side surface of the second barb 502b to form elastic potential energy.
Thus, in summary, the initial state (unlocked state) of the locking assembly 502 is: the limiting piece 502c is located in the ring of the second rotating ring 502a, and the second rotating ring 502a cannot rotate, so that the second barb 502b cannot be embedded into the locking channel 402 to be locked. In this state, the above-described temporary locking and unlocking process can be achieved by simply twisting the rotation knob 503b-2.
The lock-up state of the locking assembly 502 is: pushing the first driving member 503a (the pushing force is greater than the elastic force of the second elastic member 502 d), so that the inner end of the first driving member 503a pushes the limit piece 502c out of the ring of the second rotating ring 502 a. Because there is no rotation restriction of the limiting piece 502c to the second rotating ring 502a (the limiting piece 502c cannot rotate all the time and can only slide), the second barb 502b rotates clockwise along with the second rotating ring 502a under the elastic force of the third elastic piece 502e-1 until the hook head of the second barb 502b is completely inserted into the locking channel 402, so as to form a lock.
The process of unlocking the locking assembly 502 is: pushing the first driving member 503a inwardly until the pushing cannot be continued, at which time the male protrusion 503a-1 on the first driving member 503a is not aligned with the second notch 502a-1 of the second rotating ring 502a, thereby rotating the first driving member 503a until the male protrusion 503a-1 is spatially aligned with the second notch 502a-1 and pushing the insertion; then, the first driving member 503a is reversely rotated to drive the second rotating ring 502a to reversely rotate until the second notch 502a-1 of the second rotating ring 502a is aligned with the protrusion 502c-1 of the limiting piece 502c, at this time, the limiting piece 502c pushes the limiting piece 502c into the ring of the second rotating ring 502a under the action of the second elastic member 502d, so that the original state of the locking assembly 502 is restored, and the locking state is released.
Preferably, in the present application, it is also possible to set: the second notch 502a-1 of the second rotating ring 502a is just opposite to the protruding part 503a-1 in the above-mentioned locking state (correspondingly, the initial state of the second notch 502a-1 and the protrusion 502c-1 is a position rotated counterclockwise by a corresponding angle), so the process of releasing the locking state is preferably: only the first driving member 503a is pushed to be embedded into the second rotating ring 502a, and then the first driving member is rotated counterclockwise by a corresponding angle until the first driving member faces the limiting piece 502c.
In the present application, the second locking portion 500 further includes a lock body housing 504, and the first limiting frame 501d and the second limiting frame 502c are both fixed on an inner sidewall of the lock body housing 504. In addition, the inner end of the guide member 503c is fixed to the end cap 503d, and the inner side surface of the end cap 503d is fixed to the inner side surface of the lock body case 504. The outer end of the second driving member 503b of the present application is penetrated out of the lock body case 504 and is fixed at its end with a rotation knob 503b-2.
