[0036] Example 2

[0037] Reference Figure 2-4, which is the second embodiment of the utility model. This embodiment is based on the previous embodiment, and is different from the previous embodiment in that: a gear transmission is provided, a lifting groove 101c-1 is provided in the vertical rod 101c, a shaft sleeve 101c-2 is provided at one end of the vertical rod 101c, and an annular protrusion 101c-3 is provided on the top of the shaft sleeve 101c-2; one end of the vertical rod 101c is connected to the first bevel gear 101e, and an annular groove 101e-1 is provided on the end face of the first bevel gear 101e, and the annular groove 101e-1 is matched with the annular protrusion 101c-3 in shape, a through hole 101e-2 is provided at the center of the first bevel gear 101e, and a threaded groove 101e-3 is provided in the through hole 101e-2; the driving member 103 includes a motor 103aa and a transmission shaft 103b connected to the motor 103aa, and a second bevel gear 103b-1 is provided at one end of the transmission shaft 103b.

[0038] Specifically, the inner wall of the lifting groove 101c-1 of the vertical rod 101c is provided with an internal thread, the inner diameter of the sleeve 101c-2 at one end of the vertical rod 101c matches the diameter of the lifting groove 101c-1, the shape of the annular protrusion 101c-3 at one end of the sleeve 101c-2 matches the shape of the annular groove 101e-1 of the first bevel gear 101e, and the thread groove 101e-3 of the first bevel gear 101e matches the thread of the screw 102d.

[0039] Furthermore, the connecting plate 101d is fixedly connected to one side of the vertical pole 101c, the motor 103a is arranged in the middle of the connecting plate 101d, and the two ends of the motor 103a are connected to the transmission shaft 103b, and the second bevel gear 103b-1 at one end of the transmission shaft 103b is meshed with the first bevel gear 101e.

[0040] Furthermore, the diameter of the screw rod 102d matches the diameter of the lifting groove 101c-1, and the screw rod 102d passes through the through hole of the first bevel gear 101e-1 and is inserted into the lifting groove 101c-1.

[0041] In this embodiment, when the temperature sensor detects that the temperature inside the cabinet is too high, the motor 103a is started, and the motor 103a drives the transmission shaft 103b to rotate. The rotation of the transmission shaft 103b drives the second bevel gear 103b-1 at one end to rotate. The rotation of the second bevel gear 103b-1 causes the first bevel gear 101e meshing therewith to rotate. Since the first bevel gear 101e is fixed by the annular protrusion 101c-3, the first bevel gear 101e drives the screw rod 102d to rise when it rotates. The rise of the screw rod 102d will drive the lifting plate 102a to rise, and finally the lifting platform 102 will rise. When the lifting platform 102 rises to a sufficient height, an opening is opened at the top of the cabinet to discharge the heat in the cabinet in time. , and then turn off the motor 103a; when the temperature sensor detects that the temperature in the cabinet has dropped to an appropriate range, the motor 103a is controlled to reverse, and the motor 103a drives the transmission shaft 103b to reverse, and the transmission shaft 103b reverses and drives the second bevel gear 103b-1 at one end to reverse, and the second bevel gear 103b-1 reverses to reverse the first bevel gear 101e meshing therewith. Since the first bevel gear 101e is fixed by the annular protrusion 101c-3, the first bevel gear 101e drives the screw rod to descend when it reverses, and the descent of the screw 102d will drive the lifting plate 102a to descend, and finally the lifting platform 102 will descend until the lifting platform 102 closes the opening on the top of the cabinet again, and the motor 103a stops running.

[0042] When the motor 103a is started, the first bevel gear 101e and the second bevel gear 103b-1 cooperate to realize the lifting and lowering of the screw rod 102d, and finally realize the lifting and lowering of the lifting platform 102.

[0046] Furthermore, the rack 204a on the dust cover 204 cooperates with the second bevel gear 103b-1, and the side walls of the dust cover 204 are provided with a plurality of heat dissipation openings 204b.

[0047] In this embodiment, the cabinet door 201a of the cabinet shell 201 is controlled by a switch 201b. When the staff needs to enter the cabinet, the cabinet door 201a is unlocked by the switch 201b, and then the handle 201a-1 is turned to open the cabinet door 201a to enter and exit the cabinet. The staff can also observe the situation inside the cabinet at all times through the monitoring window 201c of the cabinet shell 201; the other side of the second bevel gear 103b-1 cooperates with the rack 204a of the dust cover 204. When the temperature sensor detects that the temperature inside the cabinet is too high, when the lifting platform 102 is controlled to rise by the lifting component 100, the second bevel gear 103b-1 rotates and also drives the rack 204a to rise. , thereby driving the dust cover 204 to rise until the upper end of the dust cover 204 contacts the lifting plate 102a, and at the same time triggering the switch of the fan 203 in the heat dissipation window 202, and accelerating the heat dissipation through the fan 203. At this time, the dust cover 204 completely blocks the gap between the lifting platform 102 and the heat dissipation window 202, preventing foreign matter from entering the cabinet through the gap during heat dissipation, and continuously dissipating heat through the heat dissipation port 204b of the dust cover 204; when the lifting component 100 controls the lifting platform 204a to descend, the second bevel gear 103b-1 reverses and drives the rack 204a to descend, thereby driving the dust cover 204 to descend until the dust cover 204 retracts into the heat dissipation window 202, and the fan 203 is turned off.

[0048] Through the cooperation between the rack 204a of the dust cover 204 and the second bevel gear 103b-1, the lifting assembly 100 will also drive the dust cover 204 to rise and fall. The dust cover 204 can protect the cabinet and the lifting assembly 100, and prevent foreign matter from entering the cabinet and affecting the functions of the cabinet and the lifting assembly 100.
