Description

Technical Field

[0001] The utility model relates to an earthquake-resistant device, in particular to an earthquake-resistant device for a computer case. Background Technique

[0002] With the popularization and application of computers, computers are also configured on various mobile vehicles according to needs, such as motorhomes. However, on mobile vehicles, certain vibrations often occur, which may cause the components inside the computer case to become loose or damaged. Therefore, an earthquake-resistant device is required to dampen the vibrations of the computer case to ensure the safety of the computer.

[0003] For example, an earthquake-resistant computer case with a publication number of CN209229261U disclosed in a Chinese patent includes a case body and a placement base. In the middle of the inner cavity of the placement base, there is a placement plate. The bottom of the placement plate is connected to the bottom of the inner cavity of the placement base through multiple telescopic rods. A shock-absorbing spring is sleeved outside the telescopic rods. On both sides of the bottom of the placement plate, there are clamping devices. The clamping device includes a first connecting rod, a first slider, a second connecting rod, a second slider, a mounting rod, and a clamping roller. On both sides of the bottom of the placement base, mounting plates are welded and fixed. Threaded rods are symmetrically penetrated through the mounting plates in the front and back. A universal roller is welded and installed at the bottom end of the threaded rod. The utility model is provided with a clamping device, which can automatically clamp and fix by using gravity, avoiding the case body from being touched. At the same time, the greater the amplitude of the vibration, the greater the clamping force of the clamping roller on it, achieving a further shock-absorbing effect. It is provided with mounting plates, threaded rods, and universal rollers, which is convenient for movement;

[0004] When the above-mentioned existing earthquake-resistant device for a computer case is used, some problems are found. First of all, the vibration is not only downward. When the vibration direction is upward, the clamping force of the clamping roller will become smaller, and at this time, the case is prone to loosen and fall. Summary of the Utility Model

The clamping mechanism includes a clamping plate and two side limiting plates. A second limiting groove is opened in the clamping plate. A second limiting slider is fixedly connected to the side limiting plate. The second limiting slider is slidably matched with the second limiting groove.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 3 , the present invention provides a technical solution: an anti-seismic device for a computer chassis, including a fixed base 1 and a computer chassis 6. Shock-absorbing mechanisms 2 are fixedly connected to the positions near the four corners and edges of the upper surface of the fixed base 1. A fixed table 3 is fixedly connected to the upper ends of the shock-absorbing mechanisms 2. Two clamping mechanisms 4 are symmetrically and slidably connected to the front and rear of the upper surface of the fixed table 3. A telescopic adjustment rod 5 is fixedly connected to the upper surface of the rear clamping mechanism 4. A pressing plate 504 is fixedly connected to the upper end of the telescopic adjustment rod 5. The clamping mechanism 4 includes a clamping plate 401 and two side limit plates 402. A second limit groove 403 is formed in the clamping plate 401. Second limit sliders 407 are fixedly connected to the side limit plates 402. The second limit sliders 407 are slidably matched with the second limit groove 403.

[0021] In this implementation scheme, by placing the computer chassis 6 on the fixed platform 3, adjusting the distance between the two clamping mechanisms 4, so that the clamping plates 401 clamp the computer chassis 6 front and back. At the same time, the second limit slider 407 is slidably matched with the second limit groove 403, and the side limit plate 402 is slidably connected to the clamping plate 401. By adjusting the distance between the two clamping plates 401, it can clamp both sides of the computer chassis 6 and limit the left and right sliding of the computer chassis 6. The upper end of the telescopic adjusting rod 5 is connected with a pressing plate 504. By adjusting the length of the telescopic adjusting rod 5, the pressing plate 504 presses the upper surface of the computer chassis 6 to prevent the computer chassis 6 from bouncing upward relative to the fixed platform 3. Furthermore, the computer chassis 6 is fixed on the fixed platform 3, avoiding the problem that the computer chassis 6 slips and topples due to vibration. The fixed platform 3 is connected to the fixed base 1 by a damping mechanism 2, and the damping mechanism 2 can provide a certain damping capacity for the fixed platform 3, thereby attenuating the vibration transmitted to the computer chassis 6 and preventing damage to the internal components of the computer chassis 6.

[0022] Among them, in order to achieve the purpose of damping, the following technical solutions are adopted in this device: Rubber damping fixing feet 101 are fixedly connected to both sides of the fixed base 1. The damping mechanism 2 includes a damping telescopic rod 201 and a damping spring 202. The upper and lower ends of the damping telescopic rod 201 are fixedly connected to the fixed base 1 and the fixed platform 3 respectively. The damping spring 202 is sleeved on the damping telescopic rod 201. First limit sliding grooves 301 are symmetrically arranged front and back on the upper surface of the fixed platform 3. First limit sliders 405 are fixedly connected to the lower surface of the clamping plate 401, and the first limit sliders 405 are slidably matched with the first limit sliding grooves 301.

[0023] The fixed base 1 can be fixed in a suitable position by bolts through the rubber damping fixing feet 101. At the same time, the rubber damping fixing feet 101 are made of rubber material, which can further provide a certain damping capacity for the device. The damping telescopic rod 201 itself has a certain damping, and it cooperates with the damping spring 202 to be able to provide a certain damping capacity for the fixed platform 3. The first limit sliders 405 are slidably matched with the first limit sliding grooves 301, and then the clamping plate 401 is slidably installed on the fixed platform 3.

[0024] Among them, in order to achieve the purpose of fixing the computer chassis 6, the following technical solutions are adopted in this device: A first bidirectional threaded rod 302 is rotatably installed in the fixed platform 3. A first threaded hole 406 is formed in the first limit slider 405, and the first threaded hole 406 is threadedly matched with the first bidirectional threaded rod 302. A second bidirectional threaded rod 404 is rotatably installed in the second limit groove 403. A second threaded hole 408 is formed in the second limit slider 407, and the second threaded hole 408 is threadedly matched with the second bidirectional threaded rod 404. The telescopic adjusting rod 5 includes a threaded sleeve 501 and two threaded connecting rods 503. The two threaded connecting rods 503 are threadedly installed at both ends of the threaded sleeve 501, and a knob 502 is fixedly connected to the threaded sleeve 501.

[0025] Through the threaded fit between the first bidirectional threaded rod 302 and the first threaded hole 406, rotating the first bidirectional threaded rod 302 can drive the first limit slider 405 to move. The movement of the first limit slider 405 can drive the clamping plate 401 to move, thereby adjusting the distance between the two clamping plates 401. The second threaded hole 408 is in threaded fit with the second bidirectional threaded rod 404. Rotating the second bidirectional threaded rod 404 can drive the second limit slider 407 to move. The movement of the second limit slider 407 can drive the side limit plate 402 to move, thereby adjusting the distance between the two side limit plates 402. The side limit plates 402 are used to clamp both sides of the computer case 6. The threaded sleeve 501 is in threaded fit with the threaded connecting rod 503. Rotating the threaded sleeve 501 with the knob 502 can adjust the distance between the two threaded connecting rods 503, and then drive the pressing plate 504 to move, so that the pressing plate 504 presses against the top of the computer case 6. The adjustable pressing plate 504, side limit plates 402, and clamping plates 401 enable computer cases 6 of different sizes and specifications to be fixed on the fixing table 3.

[0026] The working principle and usage process of the present utility model: When in use, first, the fixing base 1 needs to be fixed at a suitable position by using bolts and rubber shock-absorbing fixing feet 101. Place the computer case 6 on the fixing table 3. Rotate the first bidirectional threaded rod 302 to drive the clamping plate 401 to move, and use the two clamping plates 401 to clamp and fix the fixing table 3 front and back. Subsequently, rotate the second bidirectional threaded rod 404 to drive the side limit plates 402 to clamp both sides of the computer case 6. Rotate the threaded sleeve 501 with the knob 502. The rotation of the threaded sleeve 501 will adjust the distance between the two threaded connecting rods 503, and then drive the pressing plate 504 to press down on the computer case 6. When the device is vibrated, the shock-absorbing mechanism 2 can reduce the vibration transmitted to the fixing table 3, thereby preventing the computer case 6 from being strongly vibrated and ensuring the safety of the internal components of the case.

[0027] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
