Referring to fig. 1,5 and 6, a locking groove 28 is formed in the top surface or the bottom surface of the plate body 21, a self-locking mechanism 29 locked with the locking groove 28 is arranged on the inner wall of the cabinet door 11, the self-locking mechanism 29 comprises a shell 291, a locking piece 292 and a memory spring 293, a movable groove 30 for sliding connection of the locking piece 292 is formed in the shell 291, a travel groove 31 is formed in the inner wall of the movable groove 30, a travel block 32 which is connected in the travel groove 31 in a sliding manner is arranged on the inner wall of the movable groove 30, and two ends of the memory spring 293 are fixedly arranged on opposite sides of the travel groove 31 and the travel block 32 respectively. The lock 292 has a tendency to protrude from the housing 291 by the action of the memory spring 293, the lock 292 protrudes outside the housing 291, and the end of the lock 292 forms a guide surface 33 inclined toward the plate body 21. When the cabinet door 11 is close to the cabinet body 1, the self-locking mechanism 29 is close to the corresponding equipment assembly plate 2, the guide surface 33 is abutted to the corresponding plate body 21, along with the closing of the cabinet door 11, under the action of the guide surface 33, the plate body 21 trend locking piece 292 is retracted into the movable groove 30 until the movable groove 30 corresponds to the locking groove 28, the memory spring 293 is restored to deform so as to drive the locking piece 292 to extend outwards, the end part of the locking piece 292 is inserted into the locking groove 28, the inner groove wall of the locking groove 28 is in interference fit with the guide surface 33, and the cabinet door 11 is locked on the cabinet body 1 through the respective locking mechanism 29, so that the cabinet door 11 is prevented from being opened due to the action of external force.
The memory spring 293 is made of memory alloy, heat generated during operation of the information device is transferred to the self-locking mechanism 29, and the memory spring 293 is contracted due to the fact that the temperature to which the memory spring 293 is subjected is too high, for example, the memory spring 293 is wound by using a CuZnAl memory alloy wire, the expansion temperature is 65-85 ℃, the free state is 200mm at low temperature (room temperature), and the shortened state is 100mm at high temperature (65-85 ℃), which is not described in detail in the prior art.
When the information equipment in the installation space 3 is overheated in operation, the liquid cooling assembly 7 is used for carrying out liquid cooling heat dissipation treatment on the equipment assembly plate 2 and the air cooling pipe 5, under the condition that if the information equipment is still overheated but the overheat condition is not serious, the memory spring 293 is heated and contracted to drive the locking piece 292 to translate upwards, when the temperature received by the memory spring 293 does not reach the telescopic temperature, the translation stroke of the locking piece 292 is smaller, the locking piece 292 is still positioned in the locking groove 28, the air cooling pipe 5 and the liquid cooling assembly 7 are matched for carrying out cooling treatment on the inner wall of the cabinet body 1, so that heat can be discharged under the condition that the cabinet door 11 is closed, and meanwhile, the shielding function of the electromagnetic shielding cabinet can be ensured not to be influenced.
Preferably, the cabinet door 11 is provided with a temperature alarm 36, and when the temperature in the cabinet body 1 exceeds a critical value set by a user, an alarm is sent to the outside, the critical value can be the expansion temperature of the memory spring 293, and the temperature alarm 36 is in the prior art and is not described in detail herein.
When the information equipment in the installation space 3 is overheated in the operation, carry out liquid cooling heat dissipation through liquid cooling subassembly 7 to equipment assembly plate 2 and air-cooled pipe 5, in this case, if the information equipment still is overheated and the overheated condition is comparatively serious, memory spring 293 is heated to stretch in order to drive locking piece 292 and upwards translate, the temperature that memory spring 293 received reaches flexible temperature, the translation stroke of locking piece 292 is great, make locking piece 292 break away from locking groove 28, unblock between cabinet door 11 and the equipment assembly plate 2, simultaneously, the alarm of temperature alarm 36 notifies the staff, in time open cabinet door 11 in time cooling down, and carry out emergency operation such as cutting off the power, open cabinet door 11 in addition helps the quick entering of air in order to carry out heat exchange, the cooling effect of air-cooled pipe 5 and liquid cooling subassembly 7 is strengthened, the risk of equipment damage is reduced.
Preferably, the movable slot 30 penetrates the housing 291, the end of the locking member 292 far away from the plate body 21 extends to the outer side of the housing 291, the electric push rod 34 is arranged on the inner side wall of the cabinet door 11 relative to the self-locking mechanism 29, the push rod end of the electric push rod 34 is connected with the end of the locking member 292 far away from the plate body 21, the outer side wall of the cabinet door 11 is provided with the switch button 35, the switch button 35 is electrically connected with the electric push rod 34 and controlled by the electric push rod 34, a worker needs to press the switch button 35 to start the electric push rod 34 before opening the cabinet door 11, and the electric push rod 34 drives the locking member 292 to overcome the upward translation of the memory spring 293 when being started, so that the self-locking mechanism 29 is unlocked with the equipment assembly plate 2, misoperation is prevented, and the cabinet door 11 is prevented from being opened by careless or accidental touch by the worker.
