Description

Technical Field

[0001] This utility model relates to the technical field of cabinet shockproof buffer devices, and in particular to a cabinet shockproof buffer device. Background Technology

[0002] With the rapid development of information technology, rack-mounted servers have been widely used in data centers, communication equipment rooms and other places. These racks are usually used to store various electronic devices, such as servers, switches and routers. However, rack-mounted servers face an important problem in actual use: insufficient shock resistance.

[0003] Existing server racks typically have four feet at the bottom that contact the ground. Because the base of these feet has a small area, the overall contact area between the server rack and the ground is very small. During an earthquake, the continuous ground vibrations, horizontal shaking, and vertical jolting, combined with the rack's small contact area, weight, and height, make it prone to tipping over. This damages the rack and the servers inside, disrupting the normal operation of both the rack and the servers. Therefore, a shock-absorbing device for server racks is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cabinet shock absorption device includes a base, four buffer accessories are installed at the four corners of the top of the base, a top plate is provided at the top of the buffer accessories, and a shock-absorbing accessory is provided at the center of the bottom of the top plate. The buffer accessories include a plate base that is connected and fixed to the bottom of the plate base. A sleeve plate is provided inside the plate base, and an inner plate is inserted inside the sleeve plate. The top of the inner plate is connected and fixed to the bottom of the top plate. A damping rod is provided between the inner plate and the sleeve plate, and a buffer spring is sleeved on the outside of the damping rod. The top of the buffer spring is connected and fixed to the inner wall of the inner plate, and the bottom of the buffer spring is connected and fixed to the inner wall of the sleeve plate.

[0007] Preferably, the top of the chassis base is provided with an H-shaped rib end, and the side of the chassis base is provided with an installation groove. The H-shaped rib end can reinforce the chassis base, prevent the chassis base from deforming under the weight of the cabinet, and ensure the overall strength of the chassis base.

[0008] Preferably, the sleeve plate has two threaded shaft ends on the left side, and the threaded shaft ends pass through the side of the plate base and are connected to the nut ends. The nut ends are used for fixing, which can ensure the stability of the sleeve plate installed inside the plate base and prevent the sleeve plate from easily loosening during installation.

[0009] Preferably, the bottom end of the sleeve is connected to a limiting block, and the limiting block is slidably embedded into the plate base through a limiting groove. By sliding the limiting block into the limiting groove of the plate base, the stability of the sleeve installed inside the plate base can be ensured.

[0010] Preferably, the inner insert plate has two guide strips symmetrically connected on its left and right sides, and the guide strips are embedded in the inner wall of the sleeve plate through guide grooves. The guide grooves of the sleeve plate can limit and guide the guide strips, ensuring the stability of the inner insert plate moving up and down inside the sleeve plate.

[0011] Preferably, the shock-absorbing component includes a mating plate that is connected and fixed to the bottom end of the top plate. The bottom end of the mating plate is bolted to a rubber disc, and the bottom end of the rubber disc abuts against the surface of the fixed disc. The fixed disc is bolted to the end surface of the H-shaped rib of the chassis base. The bottom end of the rubber disc is supported on the surface of the fixed disc, which can ensure the stability of the top plate installation.

[0012] Preferably, the rubber disc is composed of a disc end and a rubber column end. A protrusion end is provided at the center of the bottom end of the rubber disc, and the protrusion end is inserted into the fixed disc through a positioning groove. The protrusion end at the bottom of the rubber disc is inserted into the positioning groove of the fixed disc, which facilitates the assembly when the fixed disc and the rubber disc are connected.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. By setting four buffer accessories, the device can absorb and cushion the impact of vibration. Compared with the traditional structure, this device moves within the sleeve through an inner insert plate. During the movement of the inner insert plate, the buffer spring can be compressed and deformed. The compressed buffer spring can buffer the impact force generated during vibration, reducing the impact of earthquake impact on the top plate. At the same time, it expands the contact area between the chassis and the ground, reducing the probability of the top cabinet of the top plate tipping over and ensuring the normal use of the cabinet and server.

[0015] 2. By setting up shock-absorbing components, the stability of the top cabinet of the top plate is ensured. This device connects to the top end of the rubber plate through a docking plate. The bottom end of the rubber plate is supported on the surface of the fixed plate. Under normal conditions, the docking plate, rubber plate and fixed plate are supported between the chassis base and the top plate, maintaining the stability of the top cabinet of the top plate. The rubber plate is designed with elasticity, which can relieve stress during deformation. After the stress is relieved in a short time, it can quickly return to its original position, ensuring the stability of the top cabinet of the top plate. Attached Figure Description

A damping rod 27 is provided between the inner insert plate 24 and the sleeve plate 23, and a buffer spring 26 is sleeved on the outside of the damping rod 27. The top of the buffer spring 26 is connected and fixed to the inner wall of the inner insert plate 24, and the bottom of the buffer spring 26 is connected and fixed to the inner wall of the sleeve plate 23.

[0024] The top of the chassis base 1 is provided with an H-shaped rib end, and the side of the chassis base 1 is provided with an installation groove.

[0025] The left side of the sleeve 23 is provided with two threaded shaft ends, and the threaded shaft ends pass through the side of the plate base 21 and are connected to the nut end.

[0026] The bottom end of the sleeve plate 23 is connected to the limiting block 22, and the limiting block 22 is slidably embedded into the plate base 21 through the limiting groove.

[0027] Two guide strips 25 are symmetrically connected on the left and right sides of the inner insert plate 24, and the guide strips 25 are embedded into the inner wall of the sleeve plate 23 through guide grooves.

[0028] The shock-absorbing component 4 includes a mating plate 41 that is connected and fixed to the bottom end of the top plate 3. The bottom end of the mating plate 41 is connected to a rubber disc 42 by bolts, and the bottom end of the rubber disc 42 abuts against the surface of the fixed disc 43. The fixed disc 43 is fixed to the surface of the H-shaped rib end of the chassis base 1 by bolts.

[0029] The rubber disc 42 consists of a disc end and a rubber column end. A protruding end is provided at the center of the bottom end of the rubber disc 42, and the protruding end is inserted into the fixed disc 43 through a positioning groove.

[0030] The H-shaped ribs can reinforce the chassis base 1, preventing it from deforming under the weight of the cabinet and ensuring its overall strength. The mounting groove design on the side of the chassis base 1 allows it to be easily fixed to the ground surface using ground anchors or long screws, ensuring the stability of the chassis base 1. When the sleeve plate 23 is installed inside the plate base 21, the threaded shaft end of the sleeve plate 23 passes through the side of the plate base 21 and is fixed by the nut end, ensuring the stability of the sleeve plate 23 inside the plate base 21 and preventing it from easily loosening during installation.

[0031] By sliding the limiting block 22 into the limiting groove of the plate base 21, the stability of the sleeve plate 23 installed inside the plate base 21 can be ensured, and the sleeve plate 23 can be prevented from shaking during installation.

Two shaft ends are provided on the left side of the sleeve plate 23, passing through the side of the plate base 21 and locked in place with nuts. When the cabinet above the top plate 3 vibrates or shakes, the force of the vibration on the top plate 3 can be neutralized and dissipated by the elastic compression of the buffer spring 26. The damping rod 27 between the inner insert plate 24 and the sleeve plate 23 prevents the inner insert plate 24 from frequently shaking up and down within the sleeve plate 23 under the elastic force of the buffer spring 26. (According to the attached...) Figure 4 As shown, when the top plate 3 shakes, the top plate 3 can simultaneously drive the rubber disc 42 to compress on the surface of the fixed disc 43, and the rubber disc 42 can relieve and buffer the impact force during vibration.
