Description

Technical Field

[0001] The present invention relates to the field of computer technology, and more particularly to a hard disk cabinet for storing computer data. Background Art

[0002] A hard drive cabinet is a device that can provide a suitable storage environment for computer hard drives. By connecting to a computer, the computer can be connected to multiple hard drives inside the hard drive cabinet at the same time, thereby increasing the computer's data capacity and facilitating the management of hard drives. A vertical hard drive cabinet is a type of hard drive cabinet. Its advantage is that it is easy to install hard drives. A vertical hard drive cabinet is mainly composed of three parts, namely a cabinet body, a hard drive cover, and a protective top cover. There is space inside the cabinet body for installing and storing two or more hard drives. The protective top cover is used to cover the cabinet body space. The hard drive cover is installed on the outside of the hard drive. While protecting the hard drive, it also facilitates the connection between the hard drive and the cabinet body through the socket. When in use, the hard drive is installed inside the hard drive cover, and then the hard drive cover is inserted into the cabinet body. The cabinet body is connected to the computer through a data cable, and the computer can directly read and write data in multiple hard drives and manage multiple hard drives.

[0003] However, the existing hard disk cabinets still have the following shortcomings:

[0004] First, the existing vertical hard disk cabinet stores the hard disk upright, and the hard disk socket is placed downward into the cabinet body. Under the auxiliary effect of gravity, it is easy to connect the hard disk and the cabinet body socket, and the sockets of the two will not become loose due to long-term use. However, when taking out the hard disk, it is difficult to remove the hard disk due to the connection between the hard disk and the cabinet body and the large friction. In addition, the hard disk is prone to sudden fall after being placed in the cabinet, causing collision damage at the hard disk interface;

[0005] Second, existing hard disks can only store data and connect them to computers, without considering the problem that sudden removal of a hard disk connected to a computer may damage the hard disk, reduce the service life of the hard disk, or even cause the hard disk space to crash and destroy data. Summary of the invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a hard disk cabinet for storing computer data to solve the problems existing in the above-mentioned background technology.

[0007] The present invention provides the following technical solution: a hard disk cabinet for storing computer data, comprising a hard disk case, the top of the hard disk case is movably connected to a top cover plate, a square space is present inside the hard disk case, the space opens upward, a hard disk assembly is movably connected inside the hard disk case, an indicator board is fixedly connected to one side of the top cover plate, a handle located at the bottom of the indicator board is fixedly connected to one side of the hard disk case, a connection line for connecting a computer is fixedly connected to one side of the hard disk case, a switch located at one side of the connection line is movably connected to one side of the hard disk case, a hinge is movably connected to the top of the hard disk case, and a rear baffle is fixedly connected to one side of the hard disk case. The upper surface of the rear baffle is movably connected to two hinges, the hard disk case is internally movably connected to a movable protrusion, the top of the handle is movably connected to an air port, the upper surface of the air port is fixedly connected to an air valve sheet, the outer surface of the hard disk assembly is fixedly connected to a hard disk cover, both sides of the lower surface of the hard disk case are fixedly connected to rubber feet, the top cover is movably connected to the rear baffle through a hinge, the bottom of the rear baffle is fixedly connected to a power supply, the bottom of the internal space of the hard disk case is movably connected to a placement rack, the top of one side of the hard disk case is movably connected to a top cover limiter, and the side wall surface of the internal space of the hard disk case is fixedly connected to a limiting side rod.

[0008] Furthermore, a socket is fixedly connected to the middle part of the lower surface of the hard disk cover, square grooves are opened at the four corners of the lower surface of the hard disk cover, a buffer pad is fixedly connected inside the square groove of the hard disk cover, and both sides of the hard disk cover are movably connected with limited side rods, the placement rack includes an air-permeable plate, both sides of the air-permeable plate are fixedly connected with limit plates with cavities inside, one side of the limit plate is movably connected with two buffer legs, the middle part of the upper surface of the air-permeable plate is fixedly connected with a connector, both sides of the bottom of the limit plate are fixedly connected with connecting pipes, the lower surface of the air-permeable plate is movably connected with two fans, the bottom of the fan is transmission-connected with a rotator, the bottom of the air-permeable plate is fixedly connected with a plug base located in the middle of the two fans, and the limit plate The top cover limiter comprises a connecting plate, one end of the connecting plate is fixedly connected to a movable plate located on one side of the hard disk case, one side of the upper surface of the connecting plate is fixedly connected to a grab hook, the connecting plate is movably connected to a rotating rod inside, an air bag is fixedly connected to the lower surface of the connecting plate, the air bag and the grab hook are located in the same vertical plane, one side of the air bag is fixedly connected to an air supply pipe, one side of the inside of the hard disk case is fixedly connected to a front baffle, one side of the air supply pipe is movably connected to a magnetic block, one side of the magnetic block is fixedly connected to an electromagnet, and the electromagnet and the front baffle are located in the same horizontal plane.

[0009] Furthermore, heat dissipation holes are provided on both sides of the hard disk case, the top cover and the indicator plate are perpendicular to each other, a lamp for displaying the number of hard disks inside the hard disk case is installed on one side of the indicator plate, a magnet is installed on the other side of the indicator plate, and the top cover is rotated by a hinge.

[0010] Furthermore, a notch is provided at one end of the movable protrusion, which functions to automatically press the movable protrusion in when the top cover is opened. After the top cover is opened to ninety degrees, the movable protrusion pushes out to fix the top cover to prevent the top cover from falling and colliding with the hard disk case to cause damage. The air port controls the air inlet and outlet through magnetic force and also acts as a counterweight. After the gas is discharged from the air port to reduce the internal air pressure, the valve sheet presses the air port down to seal it.

[0011] Furthermore, notches are provided on both sides of the top of the hard disk cover to facilitate the hard disk assembly to be removed from the inside of the hard disk cover. Vertical long grooves are provided on both sides of the hard disk cover, and the hard disk cover is inserted into the internal space of the hard disk case according to the positions of the long grooves and the limiting side rods. The limiting side rods are in full contact with the long grooves of the hard disk cover to increase friction and reduce the falling speed of the hard disk cover.

[0012] Furthermore, rubber buffer pads are installed at the four corners of the bottom of the hard disk cover to buffer the collision and vibration generated by the contact between the hard disk cover and the buffer support feet. The connecting pipe is a hollow pipe, which is used to connect the cavities between several limit plates so that the internal air pressure of the limit plates is uniformly controlled.

[0013] Furthermore, when the movable plate moves upward, the connecting plate rotates around the rotating rod, a circular pipe for accommodating the electromagnet and the magnetic block is opened inside the front baffle, and the air supply pipe is made of soft material.

[0014] Furthermore, when the airbag is inflated, if the magnetic block squeezes the air pipe, the internal gas will not overflow when the connecting plate squeezes the airbag. If the magnetic block does not squeeze the air pipe, the connecting plate can squeeze out the internal gas of the airbag, causing the grab hook to deviate.

[0015] Furthermore, when the air pressure inside the limit plate is low, the external pressure will compress the buffer foot, and the hard disk cover is installed inside the hard disk case and connected to the connector. When the internal pressure of the limit plate is the same as that of the outside world, the spring will lift up the connecting tube, and the hard disk cover will be lifted up to facilitate removal.

[0016] Technical effects and advantages of the present invention:

[0017] 1. The present invention is provided with a placement rack. When the top cover is fully opened, one side of the indicator plate is located directly above the valve plate. The indicator plate adsorbs the valve plate upward through the magnetic force so that the air port is opened, and the outside air quickly flows into the limiting plate to increase the internal air pressure. The outside air pressure no longer suppresses the buffer foot. The buffer foot is slowly lifted up by the spring, and the vertical upward force enables the socket and the connector to be safely disengaged to avoid damage to the socket and the connector due to force tilting, and facilitates the removal of the hard disk assembly. When the hard disk assembly is installed inside the hard disk cover and placed in the hard disk box, the limiting side rod provides a limiting buffering effect. When the hard disk assembly is stored in the hard disk box and the top cover is closed, the air inside the limiting plate overflows from the air port under the action of pressure, causing the buffer foot to lower. The pressure buffering of the buffer foot and the protective effect of the buffer pad avoid damage to the socket and the connector due to impact caused by the falling of the hard disk cover.

[0018] 2. The present invention is provided with a top cover limiter. After the connecting line is connected to the computer, the hard disk assembly is connected to the power supply and is in the read-write state, and the top cover is in the closed state. The air inside the limit plate is squeezed by the hard disk cover, a part of which overflows from the air port, and the other part enters the airbag to expand it. When the power is turned on, the electromagnet squeezes the magnetic block on the air pipe through repulsion. The airbag is in a sealed state at this time and the top cover cannot be opened by pressing the rotating rod offset hook. When the power is cut off, pressing the connecting plate will squeeze out the air in the airbag. This device prevents the hard disk assembly from being removed in the read-write state and causing damage, thereby ensuring the data security in the hard disk assembly.

[0035] In this embodiment, it is necessary to further explain that notches are provided on both sides of the top of the hard disk cover 201 to facilitate the hard disk assembly 2 to be removed from the inside of the hard disk cover 201. Vertical long grooves are provided on both sides of the hard disk cover 201. The hard disk cover 201 is inserted into the internal space of the hard disk case 1 according to the position of the long grooves and the limiting side rods 10. The limiting side rods 10 are fully in contact with the long grooves of the hard disk cover 201 to increase friction and reduce the falling speed of the hard disk cover 201, thereby preventing the hard disk cover 201 from falling too fast and causing excessive collision and damage to the socket 202 and the connector 114. Rubber buffer pads 203 are installed at the four corners of the bottom of the hard disk cover 201 to buffer the hard disk cover 201. 01 collision and vibration caused by contact with the buffer foot 113, the connecting tube 115 is a hollow pipe, which is used to connect the cavities between several limit plates 112 so that the internal air pressure of the limit plate 112 is uniformly controlled. When the internal air pressure of the limit plate 112 is low, the external pressure compresses the buffer foot 113, and the hard disk cover 201 is installed inside the hard disk box 1 and connected to the connector 114. When the internal pressure of the limit plate 112 is the same as that of the outside world, the spring 117 lifts the connecting tube 115, and the hard disk cover 201 is lifted up to facilitate removal. The four connecting tubes 115 are lifted and lowered synchronously to disengage the connector 114 and the socket 202 to avoid damage.

[0036] Reference Figure 8-9 The top cover limiter 12 includes a connecting plate 1201, one end of which is fixedly connected to a movable plate 1202 located on one side of the hard disk case 1, one side of the upper surface of the connecting plate 1201 is fixedly connected to a grab hook 1203, the interior of the connecting plate 1201 is movably connected to a rotating rod 1208, the lower surface of the connecting plate 1201 is fixedly connected to an air bag 1209, the air bag 1209 and the grab hook 1203 are located in the same vertical plane, one side of the air bag 1209 is fixedly connected to an air pipe 1206, one side of the interior of the hard disk case 1 is fixedly connected to a front baffle 1205, one side of the air pipe 1206 is movably connected to a magnetic block 1204, one side of the magnetic block 1204 is fixedly connected to an electromagnet 1207, and the electromagnet 1207 and the front baffle 1205 are located in the same horizontal plane;

If the magnetic block 1204 does not squeeze the air pipe 1206, the connecting plate 1201 can squeeze the internal gas of the air bag 1209 to offset the grab hook 1203. A space is opened inside the hard disk case 1 and the front baffle 1205 to enable the connecting plate 1201 to move to control the deflection of the grab hook 1203.

[0038] Working principle of the present invention:

[0039] S1. After fixing the hard disk assembly 2 to the hard disk cover 201 with screws, place the hard disk cover 201 inside the hard disk case 1 according to the position of the limiting side rod 10. The limiting side rod 10 not only limits the position of the hard disk cover 201, but also increases friction, so that the hard disk cover 201 can fall slowly, preventing the hard disk cover 201 from falling suddenly and causing damage to the hard disk assembly 2. After the hard disk cover 201 falls to the top of the buffer foot 113, gravity moves the buffer foot 113 downward, compressing the air inside the limiting plate 112. After the buffer foot 113 moves to the bottom, the connector 114 is connected to the socket 202. The excessive air pressure inside the limiting plate 112 is transmitted to the air port 501 through the connecting pipe 115. The air pressure pushes the valve plate 502 open to discharge excess air, and then the valve plate 502 falls.

[0040] S2. When taking out the hard disk cover 201, first open the top cover 3 completely. The indicator plate 4 is located directly above the air flap 502. The air flap 502 is moved upward by magnetic attraction. The air port 501 is no longer sealed. The outside air flows into the limit plate 112 through the connecting pipe 115 to increase the internal air pressure. The internal air pressure of the limit plate 112 gradually becomes the same as the outside air pressure. The buffer legs 113 are no longer affected by the air pressure and are lifted up by the springs 117. The four buffer legs 113 hold the hard disk from the four corners. The cover 201 is lifted up to make the socket 202 and the connector 114 come out safely, so as to avoid the socket 202 and the connector 114 being damaged by the force tilting. The hard disk cover 201 is lifted up from the inside of the hard disk box 1, so as to facilitate the removal of the hard disk assembly 2, and it is more convenient to use. When the hard disk assembly 2 is installed inside the hard disk cover 201 and placed in the hard disk box 1, the pressure buffering of the buffering feet 113 and the protective function of the buffer pad 203 prevent the hard disk cover 201 from falling and hitting the socket 202 and the connector 114 and damaging them.

[0041] S3. Connect the connecting line 6 to the computer and the hard disk assembly 2 is connected to the power supply and is in the read-write state. At this time, the top cover 3 is in the closed state, and the air inside the limit plate 112 is squeezed by the hard disk cover 201. A part of the air overflows from the air port 501, and the other part enters the air bag 1209 to expand it, and one end of the connecting plate 1201 is lifted up. The electromagnet 1207 uses magnetic force to press the magnetic block 1204 against the air pipe 1206, so that the air inside the air bag 1209 is not easily squeezed out, and the air bag 1209 cannot be deformed by pressing the rotating rod 1208 to offset the grab hook 1203 to open the top cover 3. After the power is cut off, the magnetic block 1204 no longer squeezes the air pipe 1206. Pressing the connecting plate 1201 will squeeze out the air in the air bag 1209, causing the grab hook 1203 to offset before the top cover 3 can be opened. This device prevents the hard disk assembly 2 from being removed in the read-write state and causing damage.
