DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-Figure 12 A safety protection device for a computer information processing device comprises a cabinet 1, a protection groove 2 is provided on the surface of the cabinet 1, and sliding openings 3 are provided on the left and right groove walls of the protection groove 2. A bearing plate 4 for installing a computer information processing device is slidably arranged in the two sliding openings 3, and a cabinet door 5 is fixedly installed at one end of the bearing plate 4 close to the groove of the protection groove 2. A through opening is symmetrically provided on the surface of the cabinet door 5, and a rotating shaft 6 is rotatably installed in the through opening. A clamping block 7 is symmetrically fixedly installed on the surface of one end of the rotating shaft 6, and a sprocket 8 is fixedly installed on the other end of the rotating shaft 6. The sprocket 8 is connected to the cabinet door 5 through an elastic component. The elastic component comprises a first torsion spring 12 sleeved on the rotating shaft 6, and the two ends of the first torsion spring 12 are respectively fixedly connected to the sprocket 8 and the cabinet door 5.

[0020] The cabinet 1 has a first slot 9 symmetrically provided on its surface for inserting the end of the shaft 6 , a circular engaging slot 10 provided on its wall, and a second slot 11 symmetrically provided on its wall for inserting two engaging blocks 7 .

[0021] In the initial state, that is, when the rotating shaft 6 is under the elastic potential energy of the first torsion spring 12 , the two clamping blocks 7 at the ends thereof do not correspond to the positions of the two second slots 11 .

[0022] The carrying plate 4 can slide in the protective groove 2. When the cabinet door 5 and the cabinet body 1 need to be locked, the two rotating shafts 6 need to be controlled to rotate so that the two clamping blocks 7 at the ends of the rotating shaft 6 correspond to the positions of the multiple second slots 11 respectively, and then the cabinet door 5 is pushed to make the cabinet door 5 approach the cabinet body 1. In this process, the ends of the two rotating shafts 6 will pass through the two first slots 9 respectively, and the multiple clamping blocks 7 will pass through the multiple second slots 11 respectively, until the cabinet door 5 and the cabinet body 1 are abutted. At this time, the clamping blocks 7 will all be located in the clamping groove 10, and then the rotating shaft 6 is released. The rotating shaft 6 will quickly rotate and reset with the two clamping blocks 7 under the elastic potential energy of the first torsion spring 12, and the two clamping blocks 7 will rotate until they no longer correspond to the positions of the two second slots 11. The surface of the clamping block 7 will abut against the groove wall of the clamping groove 10, thereby forming a clamping connection. At this time, the movement of the cabinet door 5 cannot be controlled.

[0023] When it is necessary to inspect and repair the computer information processing device located on the carrier plate 4, first control the two rotating shafts 6 to rotate so that the multiple card blocks 7 are rotated to correspond to the positions of the multiple second slots 11. At this time, the control cabinet door 5 is moved in the direction away from the cabinet body 1, and the carrier plate 4 is pulled out of the protective groove 2 to inspect and repair the computer information processing device located on the upper surface of the carrier plate 4. The maintenance personnel can have all-round contact with the equipment and have sufficient operating space. Whether it is using a screwdriver to tighten screws, using tweezers to clamp foreign objects or combing internal circuits, they can do it with ease, which greatly improves the inspection and maintenance efficiency. At the same time, move the device out of the protective groove 2, under sufficient external light conditions, with the help of multi-angle lighting fixtures, the internal structure of the equipment and the status of components are clear at a glance, which can accurately locate the problem and reduce the chance of misjudgment.

[0024] A chain 13 is meshed and wound around the two sprockets 8, and the chain 13 is slidably connected to the cabinet door 5 through a sliding component. The sliding component includes two sliding rods 14 fixedly installed on the surface of the chain 13, and sliding grooves 15 are symmetrically opened on the surface of the cabinet door 5. One end of the two sliding rods 14 is slidably configured in the two sliding grooves 15 respectively.

[0025] By rotating one of the rotating shafts 6, under the transmission effect of the two sprocket wheels 8 and the chain 13, the other rotating shaft 6 will also rotate together, and under the effect of the slide bar 14 and the slide groove 15, the chain 13 can be prevented from separating from the sprocket wheel 8.

[0026] A fixing rod is fixedly mounted on the surface of the sprocket 8 , an adjusting wheel 16 is fixedly mounted on one end of the fixing rod, and an anti-skid pattern is provided on the surface of the adjusting wheel 16 .

[0027] The adjusting wheel 16 is convenient for controlling the rotation of the rotating shaft 6 and the sprocket 8, and the anti-skid pattern can increase the friction between the palm and the contact surface of the adjusting wheel 16 to prevent the hand from slipping.

[0028] A heat dissipation port is provided on the back of the cabinet 1, and a filter 17 is rotatably installed in the heat dissipation port. Support rods are symmetrically fixedly installed in the protective groove 2, and a mounting ring 31 is fixedly installed between the ends of the two support rods that are close to each other. A drive motor 18 is fixedly installed in the mounting ring 31, and a reciprocating screw rod 19 is fixedly installed on the output shaft of the drive motor 18. An exhaust fan blade 20 is fixedly sleeved on the reciprocating screw rod 19, and the exhaust fan blade 20 corresponds to the position of the heat dissipation port. One end of the reciprocating screw rod 19 is fixedly connected to the surface of the filter 17 through a connecting rod 35.

[0029] The heat dissipation port facilitates the heat generated by the computer information processing device when it is working to be dissipated from the cabinet 1, and the filter 17 can prevent impurities in the outside from entering the cabinet 1 through the heat dissipation port. At the same time, the exhaust fan blades 20 can be driven by the driving motor 18 to rotate, thereby accelerating the efficiency of heat in the cabinet 1 being discharged from the heat dissipation port.

[0030] The back of the cabinet 1 is symmetrically provided with knocking assemblies, and the two sets of knocking assemblies are used for intermittently knocking the filter 17. The knocking assemblies include multiple spring rods 21, a moving plate 22 fixedly installed at one end of the multiple spring rods 21, and multiple knocking balls 23. Multiple cross bars 24 are fixedly installed on the surface of the moving plate 22. Multiple knocking balls 23 are respectively fixedly installed at one end of the multiple cross bars 24 and are all against the filter 17. One end of the spring rod 21 is fixedly connected to the back of the cabinet 1. The two moving plates 22 are controlled by the pressing assembly to move away from the cabinet 1. The pressing assembly includes a slide plate 25 threadedly sleeved on the reciprocating screw rod 19, two mounting rods 26 symmetrically fixedly mounted on the slide plate 25, and two resisting rods 27. A circular opening is symmetrically provided on the back of the cabinet 1. The two mounting rods 26 are respectively slidably inserted into the two circular openings. A rectangular opening is provided on the surface of the movable plate 22. A rotating rod is vertically rotatedly installed in the rectangular opening. A resisting plate 28 is fixedly sleeved on the rotating rod. A second torsion spring 29 is symmetrically sleeved on the rotating rod. The two ends of the second torsion spring 29 are respectively fixed to the wall of the rectangular opening and the surface of the resisting plate 28. The stop plate 28 is fixedly connected, and the end away from the rotating rod is limited by the limiting component to rotate in the direction away from the cabinet 1. The limiting component includes a stop rod 32 located in the rectangular opening, and the bottom end of the stop rod 32 is fixedly connected to the bottom wall of the rectangular opening, and the surface of the stop rod 32 is against the side of the stop plate 28 away from the cabinet 1. A rectangular block is fixedly installed at one end of the mounting rod 26, and a through hole is opened on the surface of the rectangular block. Two stop rods 27 are respectively slidably inserted in the two through holes, and the ends of the two stop rods 27 away from each other are fixedly installed with mounting plates, and the stop rods 27 are fixedly installed with mounting plates. A telescopic spring 30 is sleeved, and the two ends of the telescopic spring 30 are fixedly connected to the mounting plate and the rectangular block respectively. The two abutment plates 28 correspond to the positions of the two abutment rods 27 respectively. A driving assembly is provided on the back of the cabinet 1. The driving assembly is used to control the two abutment rods 27 to move away from each other. The driving assembly includes two horizontal plates symmetrically fixedly installed on the back of the cabinet 1 and two vertical rods 33 respectively fixedly installed vertically on the upper surfaces of the two horizontal plates. Inclined plates 34 are fixedly installed on the surfaces of the two rectangular blocks, and the two vertical rods 33 correspond to the positions of the two inclined plates 34 respectively.

[0031] In the initial state, the multiple knocking balls 23 will all be against the surface of the filter 17 under the elastic potential energy of the spring rod 21, and the abutment plate 28 will be against the blocking rod 32 under the elastic potential energy of the second torsion spring 29, and the two abutment rods 27 will correspond to the positions of the two abutment plates 28 respectively under the elastic potential energy of the telescopic spring 30.

[0032] When the driving motor 18 drives the reciprocating screw 19 to rotate, the slide plate 25 threadedly connected to the reciprocating screw 19 will drive the two mounting rods 26 and the two push rods 27 to perform horizontal reciprocating movement. When the two push rods 27 move in the direction away from the cabinet 1, the surfaces of the two push rods 27 will respectively resist the surfaces of the two push plates 28. Since the push plates 28 are restricted by the blocking rod 32, the ends of the push plates 28 away from the rotating rod cannot rotate in the direction away from the cabinet 1. Therefore, under the pushing action of the push rods 27, the two movable plates 22 will move in the direction away from the cabinet 1. At this time, the multiple spring rods 21 will be stretched together, and the multiple knocking balls 23 will be away from the surface of the filter 17.

[0033] Then, as the push rod 27 moves, the inclined surfaces of the two inclined plates 34 will respectively resist the surfaces of the two vertical rods 33. Under the action of the inclined surface pressure, the two push rods 27 will move away from each other, and the contact area between the push rod 27 and the push plate 28 will gradually decrease. When the push rod 27 and the push plate 28 are no longer in contact, the thrust given by the push rod 27 to the push plate 28 and the moving plate 22 disappears, and the moving plate 22 will quickly move and reset under the elastic potential energy of the multiple spring rods 21, and the multiple knocking balls 23 will also collide with the filter 17.

[0034] Then, when the push rod 27 moves in the direction closer to the cabinet body 1, the push rod 27 will abut against the surface of the push plate 28 away from the cabinet body 1. At this time, the end of the push plate 28 away from the rotating rod will rotate in the direction close to the cabinet body 1 under the pressure of the push rod 27, until the push rod 27 no longer abuts against the push plate 28, the push plate 28 will quickly rotate and reset under the elastic potential energy of the second torsion spring 29, and the surface of the push plate 28 away from the cabinet body 1 will abut against the surface of the vertical rod 33 again, and then the push rod 27 moves in the direction away from the cabinet body 1 again, and the above steps are repeated to achieve intermittent collision of multiple knocking balls 23 with the filter 17.

[0035] The intermittent knocking of the knocking ball 23 can generate vibrations, loosening the dust particles attached to the filter 17 to prevent them from clogging due to excessive accumulation, ensuring smooth air circulation inside the cabinet 1, maintaining a stable working temperature, and preventing a large amount of dust and impurities from accumulating on the surface of the filter 17, which would cause the filter holes of the filter 17 to become clogged and affect the air permeability.

[0036] And because the output shaft of the driving motor 18 rotates with the reciprocating screw 19, the reciprocating screw 19 will also rotate with the connecting rod 35 and the filter 17. The rotation of the filter 17 and the intermittent knocking of the knocking ball 23 realize all-round dynamic cleaning of the filter 17, ensuring that the dust particles on the surface of the entire filter 17 have a chance to be shaken off. Compared with the fixed filter 17 that can only rely on local vibration cleaning, the comprehensiveness of the cleaning is greatly improved, so that the filter 17 always maintains a good permeability state.

[0037] Since the filter 17 is continuously rotating, it becomes more difficult for dust particles to adhere to the surface of the filter 17. Even if some dust tries to adhere, the intermittent vibration of the ball 23 combined with the dynamic surface of the filter 17 can quickly shake off the newly attached dust, effectively preventing dust from accumulating on the filter 17 to form a blockage, further ensuring the stability of air circulation inside the cabinet 1, and maintaining the heat dissipation conditions required for the efficient operation of the computer information processing device.

[0038] In the present invention, the locking and unlocking between the cabinet door 5 and the cabinet body 1 can be quickly completed through the cooperation between the rotating shaft 6 and the clamping block 7. At the same time, when it is necessary to repair the computer information processing device located in the cabinet body 1, the cabinet door 5 can be quickly unlocked, and then the cabinet door 5 can be pulled to pull the supporting plate 4 on which the computer information processing device is installed out of the protective groove 2. The maintenance personnel can have all-round contact with the equipment, with sufficient operating space and a wide field of vision.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
