[0014] The present invention provides a multimedia information security device with multiple interfaces. It has the following beneficial effects:

[0015] (1) The multimedia information security device drives the lower baffle to move by the upper baffle and the rotating shaft. Under the action of the forward and backward movement of the upper baffle and the lower baffle, the interface can be effectively closed to prevent foreign matter from entering the interior of the processing frame through the interface, thereby increasing the subsequent maintenance cost. At the same time, under the action of the limit rod and the limit slot, the upper baffle and the lower baffle can be further prevented from shaking, so that foreign matter can enter the interior of the processing frame through the gap.

[0016] (2) In the multimedia information security device, the movement of the device connector drives the blocking rod to move through the sliding plate and the receiving rod to release the limit on the fixed block, so that the arc-shaped clamping plate clamps the device connector to prevent the device connector from being disconnected from the device due to accidental touch, affecting the normal use of the device. At the same time, when the device connector is subjected to tension, the clamping force is increased through the clamping block to prevent the device connector from being directly disconnected due to external tension due to accidental touch, thereby affecting the normal use of the device and reducing subsequent maintenance costs.

[0017] (3) When the multimedia information security device needs to be disconnected, the device connector is pushed. Under the action of the sliding plate and the L-shaped rod, the push rod drives the block and the arc-shaped clamp to move upward. The arc-shaped clamp moves upward to release the clamp on the device connector, making it easier to disconnect the device connector and avoiding direct dragging that affects the service life of the device. At the same time, under the action of the air outlet valve and the air return valve on the surface of the slide, the arc-shaped clamp slowly resets, making it easier for the staff to pull out the device connector, extending the service life of the equipment and reducing maintenance costs.

[0018] (4) When the multimedia information security equipment needs to be repaired, the L-shaped baffle is moved to enter the movement trajectory of the quantitative box, and then the upper baffle moves downward to drive the oil storage tank downward and the lubricating oil is sprayed out under the action of the L-shaped baffle, which lubricates the surface of the rotating shaft and realizes the quantitative discharge of the lubricating oil, thereby extending the service life of the equipment, avoiding the waste of lubricating oil, and reducing maintenance costs.

At the same time, the movement of the L-shaped rod 52 drives the connecting rod 57 to move, and the movement of the connecting rod 57 drives the slide plate 56 to move and squeeze the air inside the air frame 55, so that the air flows to the left under the action of the air outlet valve on the surface of the slide plate 56.

The metering box 62 moves downward and contacts and moves upward under the action of the L-shaped baffle 66. The metering box 62 moves upward and drives the nozzle 63 upward. The nozzle 63 moves upward and drives the latch 64 upward. The latch 64 moves upward and contacts and moves downward under the action of the support plate 65 to open the outlet of the nozzle 63.
