Detailed Embodiment

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment: Please refer to Figure 1 and Figure 2 as shown, a new type of tool cabinet includes a cabinet body 1, on which there are provided several storage cavities 2 for accommodating tools and cabinet doors 102 covering each storage cavity 2. An electric control lock 201 is provided between each cabinet door 102 and the cabinet body 1, and a lock control device 101 for controlling the on / off state of each electric control lock 201 is also provided on the cabinet body 1.

[0023] As Figure 2As shown, the storage cavity 2 has a box structure with openings at both the top and the front (the top plate in the figure is the bottom plate of the upper-layer storage cavity 2). The spaces above the storage cavities 2 on the same layer are in communication with each other, and the spaces above the storage cavities 2 on different layers are communicated through the rear space of the cabinet body 1. A louver mechanism 3 that can be unfolded or closed is provided at the top of the storage cavity 2, and a drying mechanism is provided in the rear space of the cabinet body 1. The drying mechanism can be an existing ventilation mechanism, dehumidification mechanism, electric heating device, or a combination thereof, which will not be elaborated here. Since the rear space of the cabinet body 1 is in communication with the upper part of each storage cavity 2 on each layer, the drying mechanism can dehumidify and dry all the storage cavities 2. When the louver mechanism 3 in a certain storage cavity 2 is closed, the louver mechanism 3 can block the storage cavity 2 from the external space and prevent gas exchange between the storage cavity 2 and other spaces in the cabinet body 1.

[0024] On the basis of the above embodiments, a through hole 202 is opened at the covering position of the cabinet door 102 on the front surface of the cabinet body 1. A bolt 4 is movably inserted into the through hole 202. A U-shaped frame 5 is fixedly provided on the inner wall of the cabinet body 1 corresponding to the through hole 202. The tail of the bolt 4 penetrates through the U-shaped frame 5. A ring plate 401 is fixedly provided on the outer wall of the bolt 4 and inside the U-shaped frame 5. A compression spring 6 is sleeved between the U-shaped frame 5 and the ring plate 401 outside the bolt 4. When the cabinet door 102 is opened, the compression spring 6 pushes the ring plate 401 to make the bolt 4 pop out automatically. When the cabinet door 102 is manually closed, the cabinet door 102 presses the bolt 4 to retract until the cabinet door 102 is locked by the electric control lock 201. A connecting rod 304 is provided inside the cabinet body 1 and behind the tail of the bolt 4. The connecting rod 304 is slidably arranged in the front-back direction and is connected to the louver mechanism 3. When the cabinet door 102 is opened and the bolt 4 pops out, the louver mechanism 3 is in a closed state. When the cabinet door 102 is closed and the bolt 4 is pressed back, the louver mechanism 3 is in an unfolded state. Therefore, the unfolded or closed state of the louver mechanism 3 is associated with the opening and closing state of the cabinet door 102. When the cabinet door 102 is opened and not closed, the louver mechanism 3 is always in a closed state, thus preventing the hot air in the cabinet body 1 from flowing out of the storage cavity 2 and reducing heat loss.

[0025] As Figure 3 and Figure 4 As shown, the louver mechanism 3 includes blades 301 arranged at intervals in the front-back direction. The left and right ends of the blades 301 are rotatably connected to the inner wall of the storage cavity 2 through short shafts 303. A gear 302 is provided at the right end of the short shaft 303. The connecting rod 304 is arranged above the gear 302, and a rack 305 meshing with the gear 302 is provided at the bottom of the connecting rod 304 in the front-back direction. Therefore, when the bolt 4 moves, it can drive the connecting rod 304 to move back and forth. When the connecting rod 304 moves, it can drive the gear 302 to rotate, thereby adjusting the louver mechanism 3.

[0026] As Figure 5As shown, a first magnetic member 306 is fixedly provided at the rear end of the connecting rod 304, and a second magnetic member 307 is fixedly provided at the rear of the storage cavity 2 corresponding to the connecting rod 304, and the second magnetic member 307 is arranged to repel the first magnetic member 306. Since the extrusion spring 6 is relatively small, and the connecting rod 304 is relatively long and has a relatively large mass, the movement of the connecting rod 304 is easily blocked by relying solely on the extrusion spring 6. By adding the repelling first magnetic member 306 and the second magnetic member 307, the connecting rod 304 can always have a tendency to move forward, and when the latch 4 is not pressed by the cabinet door 102, it is convenient for the latch 4 to pop out and the connecting rod 304 to move forward.

[0027] On the basis of the above embodiment, a weighing sensor and a microcontroller (not shown in the figure) are provided in the storage cavity 2, an electric telescopic component is connected between the latch 4 and the connecting rod 304, and the weighing sensor, the microcontroller and the electric telescopic component are electrically connected in sequence; when the cabinet door 102 is closed, when the weighing weight of the weighing sensor is lower than a preset value, the microcontroller controls the electric telescopic component to shorten to simulate the pop-up latch 4, and the shutter mechanism 3 is in a closed state; when the weighing weight of the weighing sensor is higher than a preset value, the microcontroller controls the electric telescopic component to extend to simulate the pressing back of the latch 4, and the shutter mechanism 3 is in an expanded state.

[0028] like Figure 4As shown, the electric telescopic member includes a shaft rod 8 and a sleeve 7 slidably sleeved on the shaft rod 8, the shaft rod 8 is fixed in the circumferential direction and connected to the connecting rod 304, the sleeve 7 rotates in the circumferential direction and connected to the latch 4, and a special-shaped slide groove is provided on the sleeve 7, the special-shaped slide groove includes a first straight groove 701 and a second straight groove 703 which are vertically axially distributed and arranged in parallel, and an inclined groove 702 connecting the first straight groove 701 and the second straight groove 703 at one end, and the angles between the inclined groove 702 and the first straight groove 701 and the second straight groove 703 are both obtuse. The outer wall of the shaft rod 8 is connected to a limit rod 801, and the limit rod 801 is arranged in the special-shaped slide groove, the outer wall of the sleeve 7 is provided with a circle of gear ring 704, and the outer wall of the sleeve 7 is fixed with a micro motor 705, and the output end of the micro motor 705 is connected to a micro gear 706, and the micro gear 706 is meshed with the gear ring 704. When the cabinet door 102 is closed and the weighing value of the weighing sensor is lower than the preset value, the microcontroller controls the micro motor 705 to rotate forward. Due to the meshing action of the micro gear 706 and the ring gear 704, the sleeve 7 is in a reverse state. Since the shaft rod 8 and the connecting rod 304 can only move forward and backward, the limit rod 801 moves in the first straight groove 701, the oblique groove 702, and the second straight groove 703 in turn and is inserted into the second straight groove 703, while driving the shaft rod 8 and the connecting rod 304 to move forward, which has the same effect as opening the cabinet door 102 and popping out the latch 4, that is, the rack 305 moves forward to drive the shutter mechanism 3 until it is closed, thereby preventing the storage cavity 2 from exchanging gas with other spaces in the cabinet body 1. On the contrary, after opening the cabinet door 102, putting in tools and closing the cabinet door 102, the weighing weight of the weighing sensor is higher than the preset value, the microcontroller controls the micro motor 705 to reverse, the sleeve 7 is in a forward rotation state, and the limit rod 801 moves in the second straight groove 703, the inclined groove 702, and the first straight groove 701 in turn and is inserted into the first straight groove 701, while driving the shaft rod 8 and the connecting rod 304 to move backward, which has the same effect as closing the cabinet door 102 and pressing back the latch 4. The rack 305 moves backward to drive the shutter mechanism 3 to expand, which facilitates the gas exchange between the storage cavity 2 and other spaces in the cabinet body 1 for dehumidification and drying.
