[0024] A detachable wind and sand proof door box comprises a frame 1; a fixing frame 2 is arranged on the outer side of the frame 1, and a first storage shell 3011 and a second storage shell 3012 are connected to one side of the frame 1; an active door panel 3021 is arranged in the first storage shell 3011; a linkage door panel 3022 is arranged in the second storage shell 3012; a handle 303 is arranged on the active door panel 3021; ​​an opening and closing mechanism is arranged in the handle 303; a control mechanism 3 is arranged between the active door panel 3021 and the linkage door panel 3022.

[0025] Furthermore, the opening and closing mechanism includes a pull rod 310 and a traction rope 309; the pull rod 310 is slidably connected in the handle 303; the handle 303 is provided with a guide groove relative to the pull rod 310; an upper chamber 5 and a lower chamber 6 are provided on the side end surface of the active door panel 3021; ​​a pulley 311 is provided in the lower chamber 6; a wedge block 307 is provided in the upper chamber 5; the upper chamber 5 and the lower chamber 6 are connected through a slide groove.

[0026] Furthermore, a spring 308 is provided at the bottom of the wedge block 307 ; the upper end of the traction rope 309 is connected to the wedge block 307 , and the lower end is connected to the pull rod 310 ; the traction rope 309 is tensioned and sleeved outside the pulley 311 .

[0027] Furthermore, a slot 304 is provided on the inner side of the upper portion of the frame 1 opposite to the wedge block 307 ; the wedge block 307 is engaged in the slot 304 .

[0028] Furthermore, the spring 308 is arranged in the upper chamber 5; the spring 308 is sleeved on the outer side of the traction rope 309; and the wedge block 307 slides vertically in the upper chamber 5.

[0029] In this embodiment, the active door panel 3021 is locked by an opening and closing mechanism. After the opening and closing mechanism is opened, the active door panel 3021 can be opened; the specific opening principle is: when the pull rod 310 is pressed, the pull rod 310 can pull the traction rope 309 downward, thereby allowing the wedge block 307 to overcome the elastic force of the spring 308 and move downward, and finally the wedge block 307 is separated from the slot 304, and the active door panel 3021 can slide horizontally.

[0030] Furthermore, the control mechanism includes a telescopic rod 305; a hinge seat is provided on the opposite side of the active door panel 3021 and the linkage door panel 3022; and both ends of the telescopic rod 305 are respectively connected to the hinge seat.

[0031] Furthermore, a rotating shaft 306 is provided at the center of the surface of the telescopic rod 305 ; and a rotating bearing is provided on the inner side of the upper portion of the frame 1 relative to the rotating shaft 306 .

[0032] Specifically, when the active door panel 3021 slides horizontally, one end of the telescopic rod 305 will rotate around the rotating shaft 306, and correspondingly, the other side of the telescopic rod 305 will rotate in the opposite direction, eventually causing the linkage door panel 3022 to move in the opposite direction to the active door panel 3021, and the linkage door panel 3022 moves horizontally to a closed state. At this time, although the active door panel 3021 has been opened, the linkage door panel 3022 can still prevent wind and sand from entering.

[0033] Working principle: The fixing frame 2 is connected to the position of the indoor door frame, and the fixing bolts are passed through the fixing frame 2 to connect and fix the outer wall of the indoor door frame, so as to achieve the effect of installing and fixing the fixing frame 2 and the frame 1.

[0034] When the user needs to enter the door lobby, the handle 303 provided on a group of door panels 302 is pulled, and the pull rod 310 provided on the handle 303 is held to make the pull rod 310 provided on the handle 303 move laterally, so that the pull rod 310 moves laterally, and the traction rope 309 is driven to move during the lateral movement of the pull rod 310, so that the traction rope 309 drives the wedge block 307 to retract inwardly, so that the wedge block 307 releases the clamping and fixing effect on the slot 304, and then moves the door panel 302 laterally, so that the active door panel 3021 is opened outwardly, and at the same time, the telescopic rods 305 at both ends are turned over, so that the telescopic rods 305 at both ends drive the rotating shaft 306 to turn over along the top of the inner wall of the frame 1, so that the linkage door panel 3022 moves inwardly, and the outer door panel 302 is opened while the inner door panel 302 is closed, thereby achieving the purpose of protection, and preventing wind and sand from entering the room along the opened door panel 302 during the opening of the door panel 302, thereby affecting the cleanliness of the room.

[0035] Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the utility model rather than limiting it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
