Description

Technical Field

[0001] This utility model relates to the field of computer security protection, and in particular to a computer security protection device. Background Technology

[0002] A computer, commonly known as a PC, is a modern electronic computing machine used for high-speed calculations. It can perform numerical calculations, logical calculations, and has storage and memory functions. It is a modern intelligent electronic device that can run according to a program and automatically and quickly process massive amounts of data. It consists of a hardware system and a software system. A computer without any software installed is called a bare machine. A computer mainly includes a host and a display screen. The display screen serves as an important interface for human-computer interaction, while the host is the core component of the computer.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: Existing computer protection devices are usually exposed during operation and are easily affected by accidental impacts or collisions. Especially during movement or transportation, even slight bumps can cause internal components to loosen or be damaged, and severe impacts can even directly cause hardware failures. This situation not only affects the normal operation of the host and the security of data, but also increases maintenance costs and system risks. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing computer protection devices are usually exposed during operation and are easily subject to accidental impacts during use or transportation, which can lead to hardware failure. Therefore, we propose a computer security protection device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a computer security protection device, comprising a housing, a door rotatably connected to one side of the housing via a hinge, a handle fixedly connected to the front end of the door, a lower housing fixedly connected to both ends of one side of the housing, an upper housing fixedly connected to both ends of one side of the door, a pull rod slidably connected inside the lower housing, a circular plate fixedly connected to one end of the pull rod, a lower boss fixedly connected to the other end of the pull rod, an upper boss slidably connected to the top of the lower boss, a U-shaped elastic block fixedly connected to the top of the upper boss, and a slot for cooperating with the U-shaped elastic block provided inside the upper housing.

[0006] Preferably, a first slider is fixedly connected to the bottom of the lower boss, and a first groove is provided inside the lower housing to cooperate with the first slider.

[0007] Preferably, one end of the lower boss is fixedly connected to a first spring, and the other end of the first spring is fixedly connected to the interior of the lower housing.

[0008] Preferably, a second slider is fixedly connected to both sides of the upper boss, and a second groove is provided on both sides of the lower housing to cooperate with the second slider.

[0009] Preferably, push rods are slidably connected to both sides inside the upper housing, and a push plate is fixedly connected to one end of each push rod.

[0010] Preferably, a pull-out plate is slidably connected inside the box body, a traction rope is fixedly connected to the front end of the pull-out plate, the other end of the traction rope is fixedly connected to the box door, a second spring is fixedly connected to both sides of the pull-out plate, and a third slider is provided inside the box body to cooperate with the second spring.

[0011] Preferably, the rear end of the pull-out plate is fixedly connected to two third sliding grooves, and the other end of the third sliding groove is fixedly connected to the interior of the box.

[0012] The technical effects and advantages of this utility model are:

[0013] In this invention, pressing the circular plate moves the pull rod into the lower housing, which in turn moves the lower boss, causing it to press against the upper boss and push it upward. This pushes the U-shaped elastic block into the upper housing. During the upward movement, the two ends of the top of the U-shaped elastic block first contact the inclined surface inside the slot, and then smoothly insert into the slot, thus fixing the lower and upper housings. This structure ensures that the main unit can withstand external impacts and collisions during transportation and use, significantly reducing the risk of damage.

[0014] In this invention, after the door is released from its fixed position, pulling the handle outward causes the traction rope to move the pull plate outward. At this time, the third slide rail is in a stretched state. The structure of the second spring and the third slider ensures that the pull plate remains stable during movement, preventing wobbling and reducing friction. When it is necessary to retract the main unit into the housing, the rebound force of the third slide rail drives the pull plate to slide into the housing. Through the above structure, the operator can easily pull out and put back the main unit, thus facilitating maintenance such as cleaning and replacing parts. This reduces the tedious process of disassembling the entire protective shell and improves maintenance efficiency. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figures 1-6 As shown, this utility model provides a technical solution: a computer security protection device, including a housing 1, a door 2 rotatably connected to one side of the housing 1 via a hinge, a handle 3 fixedly connected to the front end of the door 2, a lower housing 4 fixedly connected to both ends of one side of the housing 1, and an upper housing 5 fixedly connected to both ends of one side of the door 2. A pull rod 6 is slidably connected inside the lower housing 4, a circular plate 7 is fixedly connected to one end of the pull rod 6, a lower boss 8 is fixedly connected to the other end of the pull rod 6, an upper boss 9 is slidably connected to the top of the lower boss 8, and a U-shaped elastic block 10 is fixedly connected to the top of the upper boss 9. The upper housing 5 has an opening inside that cooperates with the U-shaped elastic block 10. The slot 11, when pressed, causes the pull rod 6 to move into the lower housing 4. The pull rod 6 then moves the lower boss 8, causing the lower boss 8 to press against the upper boss 9, pushing the upper boss 9 upward and causing the U-shaped elastic block 10 to move into the upper housing 5. During the gradual upward movement, the two ends of the top of the U-shaped elastic block 10 will first contact the inclined surface opened inside the slot 11, and then smoothly insert into the slot 11, thus fixing the lower housing 4 and the upper housing 5. At the same time, through the above structure, it is ensured that the main unit can resist external impacts and collisions during transportation and use, significantly reducing the risk of damage.

[0024] Reference Figure 3 As shown in this embodiment: the bottom of the lower boss 8 is fixedly connected to the first slider 12, and the interior of the lower housing 4 is provided with a first sliding groove 13 that cooperates with the first slider 12. By setting the structure of the first slider 12 and the first sliding groove 13, the movement trajectory of the lower boss 8 can be effectively constrained, preventing shaking and tilting, and improving the stability of the device.

[0025] Reference Figure 2 As shown in this embodiment: one end of the lower boss 8 is fixedly connected to a first spring 14, and the other end of the first spring 14 is fixedly connected to the interior of the lower housing 4. Push rods 17 are slidably connected to both sides of the interior of the upper housing 5. One end of the push rod 17 is fixedly connected to a push plate 18. By setting the structure of the first spring 14, when the user pushes the lower boss 8 to squeeze the upper boss 9, the first spring 14 will be squeezed at the same time. At this time, the first spring 14 is in a compressed state. When it is necessary to release the fixation between the lower housing 4 and the upper housing 5, the push plate 18 is pushed to drive the push rod 17 to squeeze the two ends of the top of the U-shaped elastic block 10 until the U-shaped elastic block 10 is disengaged from the interior of the slot 11. At this time, the rebound force of the first spring 14 will push the lower boss 8 and the pull rod 6 to move towards the circular plate 7, which is convenient for the operator to use next time.

[0026] Reference Figure 3 As shown in this embodiment: the upper boss 9 is fixedly connected to both sides of the second slider 15, and the lower housing 4 is provided with the second slide groove 16 on both sides of the lower housing 4 to cooperate with the second slider 15. By setting the structure of the second slider 15 and the second slide groove 16, the movement direction of the upper boss 9 can be restricted and an auxiliary function can be provided to further improve the stability of the device.

[0027] Reference Figure 4 , Figure 5 and Figure 6As shown in this embodiment: a pull-out plate 19 is slidably connected inside the box body 1. A traction rope 20 is fixedly connected to the front end of the pull-out plate 19, and the other end of the traction rope 20 is fixedly connected to the box door 2. Second springs 21 are fixedly connected to both sides of the pull-out plate 19. A third slider 22 that cooperates with the second springs 21 is provided inside the box body 1. Two third sliding grooves 23 are fixedly connected to the rear end of the pull-out plate 19. The other end of the third sliding groove 23 is fixedly connected to the inside of the box body 1. After the box door 2 is released from its fixed position, the handle 3 is pulled outward, causing the traction rope 20 to drive the pull-out plate 19. 9 moves outward, at which point the third slide 23 is in a stretched state. The structure of the second spring 21 and the third slider 22 ensures that the pull plate 19 remains stable during movement, preventing shaking and reducing friction. When the main unit needs to be retracted into the housing 1, the rebound force of the third slide 23 drives the pull plate 19 to slide into the housing 1. Through the above structure, the operator can easily pull out and put back the main unit, thus facilitating maintenance such as cleaning and replacing parts. This reduces the tedious process of disassembling the entire protective shell and improves maintenance efficiency.

[0028] Working principle: By pressing the circular plate 7, the user moves the pull rod 6 into the lower housing 4. The pull rod 6 then moves the lower boss 8, causing the lower boss 8 to press against the upper boss 9, pushing the upper boss 9 upward. This, in turn, moves the U-shaped elastic block 10 into the upper housing 5. During this gradual ascent, the two ends of the top of the U-shaped elastic block 10 first contact the inclined surfaces inside the slot 11, and then smoothly insert into the slot 11, thus fixing the lower housing 4 and the upper housing 5. This structure ensures the stability of the main unit during transportation and use. During the process, it can withstand external impacts and collisions, significantly reducing the risk of damage. By setting the structure of the first slider 12 and the first groove 13, the movement trajectory of the lower boss 8 can be effectively constrained, preventing shaking and tilting, thus improving the stability of the device. By setting the structure of the first spring 14, when the user pushes the lower boss 8 to squeeze the upper boss 9, the first spring 14 will be squeezed at the same time. At this time, the first spring 14 is in a compressed state. When it is necessary to release the fixation between the lower housing 4 and the upper housing 5, the user can push the slider 12 to release the upper boss 9 to release the upper boss 9 to release the upper boss 8 ... Plate 18 drives push rod 17 to press the two ends of the top of U-shaped elastic block 10 until U-shaped elastic block 10 is disengaged from the inside of slot 11. At this time, the rebound force of the first spring 14 will push the lower boss 8 and pull rod 6 towards the circular plate 7, making it easier for the operator to use next time. By setting the structure of the second slider 15 and the second slide groove 16, the movement direction of the upper boss 9 can be restricted and an auxiliary function can be provided to further improve the stability of the device. After the door 2 is released from the fixation, pull the handle 3 outward to make the traction rope 20 drive the pull plate 19 to move outward. At this time, the third slide 23 is in a stretched state. The structure of the second spring 21 and the third slider 22 ensures that the pull plate 19 is stable during movement, avoiding shaking and reducing friction. When the main unit needs to be retracted into the housing 1, the rebound force of the third slide 23 drives the pull plate 19 to slide into the housing 1. Through the above structure, the operator can easily pull out and put back the main unit, which facilitates maintenance such as cleaning and replacing parts. This reduces the tedious process of disassembling the entire protective shell and improves maintenance efficiency.
