DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0021] Example 1, a low-voltage cabinet based on a millisecond-level optical storage system, such as Figures 1-6 and Figure 10-11 As shown, it includes a base 1 and a box body 2; the box body 2 is bolted to the base 1, and the box body 2 is set to be made of alloy; an internal circulation cooling system is set in the box body 2; it also includes a box door 3, a partition 4, a connecting block 1 5, a connecting block 2 6, a connecting block 3 7 and a fixing component; the box door 3 is plugged into the box body 2; a partition 4 is welded in the box body 2; a sealing strip is provided on the partition 4; two connecting blocks 1 5 are welded to the box body 2; each connecting block 1 5 is connected to a connecting block 2 6 by a through groove damping sliding connection; each connecting block 2 6 is rotatably connected to a connecting block 3 7, and the connecting block 3 7 is welded to the box door 3; the box door 3 is connected to a fixing component.

[0022] The fixing assembly includes a fixing block 1 201, a fixing block 202 and a latch 203; the fixing block 1 201 is bolted to the box door 3, and the fixing block 1 201 is set to a metal material; the fixing block 202 is bolted to the box body 2; a latch 203 is inserted between the fixing block 1 201 and the fixing block 2 202, and the box door 3 is fixed to the box body 2 through the cooperation of the fixing block 1 201, the fixing block 2 202 and the latch 203.

[0023] The box door 3 also includes a protrusion 204; the protrusion 204 is bolted to the box door 3.

[0024] each connecting block 26 are welded with a limit block 205, the limit block 205 contacts the door 3, the limit block 205 is used to limit the door 3, so that the door 3 can be more easily rotated to align with the box body 2 state.

[0025] First, manually remove the latch 203 upwards to stop the latch 203 and fix the fixing block 1 201 on the fixing block 2 202, then push the fixing block 1 201 forward, the fixing block 1 201 drives the box door 3 to move forward, the box door 3 drives the connecting block 3 7 to move forward, the connecting block 3 7 drives the connecting block 2 6 to slide forward in the connecting block 1 5, when the box door 3 is separated from the box body 2, manually apply a turning force to the box door 3 through the fixing block 1 201, so that the box door 3 drives the connecting block 3 7 to turn forward around the connecting block 1 5 and open, then perform electrical component installation and maintenance work in the box body 2, after which the box door 3 is manually rotated so that the box door 3 is aligned with the opening of the box body 2, and then push the box door 3 backward to move, the box door 3 drives the connecting block 3 7 backward, and the connecting block 3 7 drives the connecting block 2 6 to slide backward in the connecting block 1 5. , until the box door 3 rests on the partition 4, thereby installing the box door 3 back into the inside of the box body 2, and then inserting the latch 203 back into the fixing block 1 201 and the fixing block 2 202 to complete the closing operation of the box door 3. When in use, the box door 3 is set on the box body 2 by plugging and pulling. The plug-in fit can greatly eliminate the gap between the box body 2 and the box door 3, and effectively avoid the problem of wind and sand entering the inside of the box body 2 through the gap to ensure the normal operation of the electrical components inside the box body 2. At the same time, compared with the conventional plug-in fit, under the cooperation of the connecting block 1 5, the connecting block 2 6 and the connecting block 3 7, the box door 3 does not need to be separated from the box body 2 after opening, and is still located in the rated position of the box body 2, so that it is convenient for manual closing of the box door 3, and there is no need to carry and align the detached box door 3, thereby retaining the advantages of rotation fit.

[0026] When the box door 3 is manually driven to move forward by the fixed block 201, only one end of the box door 3 is subjected to the forward pulling force, which may easily cause the box door 3 to become stuck. Therefore, a protrusion 204 is provided at the other end of the box door 3. When the box door 3 needs to be driven forward, the box door 3 is manually driven forward by the fixed block 201 and the protrusion 204 at the same time, so that the box door 3 is subjected to balanced force and avoids the box door 3 from becoming stuck.

[0027] When the door 3 is closed, the manual operation is to rotate the door 3 back to the state flush with the box body 2, and then push the door 3 to move backward. In the process, it is necessary to ensure that the angle of the door 3 remains unchanged so that the door 3 can be accurately inserted into the box body 2, which is difficult to operate. Therefore, a stop block 205 is provided on the connecting block 26. When the door 3 is closed, the manual operation is to rotate the door 3 toward the box body 2 until the door 3 contacts the stop block 205. At this time, the door 3 is quickly positioned to the state flush with the box body 2 by the stop block 205, and then the manual operation is to apply a backward thrust to the door 3. At this time, the stop block 205 can be used to block the door 3 and prevent the door 3 from rotating. The door 3 can maintain the backward movement at an unchanged angle, so that the door 3 can be stably inserted into the box body 2. When in use, during the closing process of the door 3, the door 3 is quickly positioned by the stop block 205, and the door 3 can maintain the backward movement at an unchanged angle. There is no need for manual operation to position and maintain the angle, which is conducive to improving the convenience of manual operation.

[0028] Example 2, based on Example 1, Figure 7-Figure 9 As shown, it also includes a frame 206 and a cylinder 207; the frame 206 is welded to the box door 3, and the frame 206 is slidably connected to the partition 4; a cavity 91 is formed between the box body 2, the box door 3, the partition 4 and the frame 206; the upper part of the frame 206 is provided with an inclined portion 92; the lower part of the box body 2 is provided with an inclined portion 93; the lower part of the box body 2 is opened with a circular hole 94, which is connected to the cavity 91; the cylinder 207 is bolted to the box body 2, and the cylinder 207 is connected to the circular hole 94.

[0029] It also includes a blocking block 208; the cylinder 207 is rotatably connected to the blocking block 208 via a torsion spring shaft.

[0030] A sealing ring is provided on the outside of the block 208 , which is beneficial to improving the sealing between the cylinder 207 and the block 208 .

[0031] The surfaces of the fixing block 201 and the protruding block 204 are both roughened to increase friction and prevent slipping.

[0032] The ends of the latch 203 are chamfered to make it easier for the latch 203 to be inserted into the first fixing block 201 and the second fixing block 202 .

[0033] The surface of the frame 206 is made of a smooth material to reduce friction.

[0034] In windy and rainy weather, the sealing strip on the partition 4 is used to seal the gap between the box door 3 and the partition 4 to prevent rainwater from penetrating into the inside of the box body 2, so as to ensure the normal operation of the electrical components inside the box body 2; rainwater mixed with mud and sand will splash onto the edges of the box body 2 and the box door 3 and form agglomerates. When the box door 3 is opened, the agglomerated impurities will break up, but some impurities will still remain at the edges of the box body 2 and the box door 3. When the box door 3 is subsequently closed, the box door 3 may push the impurities remaining at the edge of the box body 2 to move, causing some impurities to be pushed into the inside of the box body 2, and causing impurities to remain in the gap between the box door 3 and the partition 4, thereby causing the sealing performance between the box door 3 and the partition 4 to deteriorate. When the box door 3 is closed, the box door 3 is manually pushed to move backward, and the box door 3 drives the frame 206 to move backward, so that the frame 206 is inserted into the partition 4. At this time, there is no contact between the box body 2 and the box door 3, and the whole formed by the box door 3, the partition 4 and the frame 206 has covered the front side of the box body 2. The box door 3 is manually pushed to continue to move backward so that the box door 3 is inserted into the box body 2. At this time, the box door 3 will disturb the movement of impurities remaining on the edge of the box 2. At this time, the partition 4 and the frame 206 can cooperate to intercept the impurities and prevent them from falling into the inside of the box 2. Figure 7 and Figure 8 As shown, when the edge of the door 3 is just inserted into the box body 2, a cavity 91 is formed between the box body 2, the door 3, the partition 4 and the frame 206, and the impurities remain in the cavity 91. The impurities move downward under the action of gravity. Under the guidance of the inclined portion 1 92 and the inclined portion 2 93, the impurities flow to the circular hole 1 94, and then flow into the cylinder 207 and are supported on the blocking block 208. Then the door 3 is manually pushed backward to close it. When in use, in the process of closing the door 3, the partition 4 and the frame 206 cooperate to intercept the impurities to prevent them from falling to the inside of the box body 2. At the same time, under the guidance of the inclined portion 1 92 and the inclined portion 2 93, the impurities in the cavity 91 will be discharged into the cylinder 207, avoiding the problem of poor sealing performance caused by impurities remaining in the gap between the door 3 and the partition 4.

[0035] During the impurity cleaning process, some dust impurities will adhere to the inner wall of the cavity 91 and cannot fall down, thereby interfering with the sealing operation between the box door 3 and the partition 4. Therefore, when the edge of the box door 3 is inserted into the inner side of the box body 2 and moves backward, the box door 3 will squeeze the air in the cavity 91, causing the air in the cavity 91 to flow into the circular hole 1 94, thereby blowing away the dust impurities adhering to the inner wall of the cavity 91 by the flowing air, preventing the dust impurities from interfering with the sealing of the box door 3 and the partition 4. After the air is squeezed into the cylinder 207, it will push the blocking block 208 to rotate around the torsion spring shaft thereon, so that the blocking block 208 stops blocking the cylinder 207, allowing the impurities in the cylinder 207 to be discharged After the box door 3 is completely closed, the cavity 91 stops supplying air to the cylinder 207, and the torsion spring shaft drives the blocking block 208 to rotate back to its original position, so that the blocking block 208 blocks the cylinder 207 again. In the normal operation of this low-voltage cabinet, the blocking block 208 prevents impurities in the external environment from entering the cylinder 207 and the circular hole 94. When in use, the air in the cavity 91 can also be squeezed during the closing process of the box door 3 to generate flowing air. The dust impurities adhering to the cavity 91 can be blown away by the flowing air, further reducing the interference with the sealing of the box door 3 and the partition 4. At the same time, the flowing air can also force the blocking block 208 to open and discharge the impurities in the cylinder 207.
