In an embodiment of the anti-seismic 5G communication cabinet of the present invention, as shown in fig. 1 to 10, the anti-seismic 5G communication cabinet includes a cabinet body 500 and an anti-seismic portion connected to the cabinet body 500, where the anti-seismic portion includes a fixing rod 100, a mounting frame 200, a fixing assembly 300, and a damping device 400.

The fixing rod 100 is fixedly connected with the mounting frame 200, the mounting frame 200 is provided with a chute 210, and the mounting frame 200 is provided with a gear 220. Two mounting frames 200 are connected to the two fixing rods 100 arranged side by side, and four gears 220 are distributed at four corners of each mounting frame 200.

The fixing assembly 300 comprises a fixing plate 340, the fixing plate 340 is provided with a sliding rail 320, a rack 330 and a fixing hole 310, the sliding rail 320 is in guiding sliding fit with the sliding groove 210, the rack 330 extends horizontally and is in meshing fit with the gear 220, and the fixing assembly 300 is connected with the cabinet body 500 of the cabinet through the fixing hole 310 and the connecting bolt 501. The mounting frame 200, the fixing component 300 and the cabinet body are fixedly connected after being adjusted to proper positions.

The damping device 400 comprises a transmission shaft 410 and a housing 460, wherein the housing 460 is provided with a cylindrical cavity, the gear 220 is sleeved on the transmission shaft 410 and rotates synchronously, and the housing 460 is fixed on the mounting frame 200. The coaxial synchronizing shaft 420 is fixedly connected to the transmission shaft 410, the synchronizing shaft 420 is located in the shell 460, the transmission shaft 410 extends out of the shell 460, the damping fixing plate 432 is fixed to the synchronizing shaft 42, two rotatable damping baffles 431 are arranged on the periphery of the synchronizing shaft 420, and the damping baffles 431 are hinged to the damping fixing plate 432 through a one-way ratchet structure and a torsion spring, so that the two damping baffles 431 can only rotate oppositely, namely, the angle between the two damping baffles 431 can only be reduced and cannot be increased in the using process. The width of the damping baffles 431 is smaller than the distance between the synchronizing shaft 420 and the outer housing 460, the swing range of each damping baffle 431 is an acute angle, the swing limit position of the damping baffles 431 is collinear with the radius of the outer housing 460, and the gap between the damping baffles 431 and the outer housing 460 is the minimum.

Two damping adjusting pieces 440 capable of rotating in one direction are arranged between the synchronizing shaft 420 and the shell 460, the two damping adjusting pieces 440 can only rotate towards the direction close to the damping baffle 431, each damping adjusting piece 440 comprises an adjusting baffle 443, liquid storage cavities 444 are connected to the opposite sides of the two adjusting baffles 443, and sealing sliders 445 are connected in the liquid storage cavities 444 in a sealing and sliding mode. The adjusting baffle 443 is connected with a shifting block 441 through a connecting rod 442, the shifting block 441 and the liquid storage cavity 444 are located on two sides of the adjusting baffle 443, and the damping baffle 431 can be shifted to swing through the shifting block 441. The width of the adjustment flapper 443 is equal to the distance between the synchronizing shaft 420 and the housing 460 and the height is equal to the height of the inner wall of the housing 460, so that the adjustment flapper 443 sealingly rotates between the synchronizing shaft 420 and the housing 460. The opposite sides of the adjusting dampers 443 of the two damping adjusters 440 are filled with damping liquid in which the two damping dampers 431 are located. A one-way valve 446 is disposed in the fluid reservoir 444 to permit one-way entry of damping fluid into the fluid reservoir 444. The other side (opposite side) of the two regulating baffles 443 is filled with gas, and in the liquid storage chamber 444, the side of the sealing slider 445 away from the regulating baffles 443 is in communication with the gas. The liquid storage chambers 444 of the two damping adjusters 440 are alternately arranged, and the tension spring 450 is connected between the alternate ends of the two damping adjusters 440.

When the anti-seismic 5G communication cabinet is used, as shown in fig. 3, if a conventional vibration occurs, the rack 330 fixedly connected with the cabinet body can rotate the gear 220 on the mounting frame 200, so as to drive the transmission shaft 410 to synchronously and reciprocally rotate, and under the pushing of the damping baffles 431, damping liquid can form clockwise or counterclockwise flow, that is, the damping liquid passes through the outer sides of the two damping baffles 431 from one regulating baffle 443 to the other regulating baffle 443, so as to generate damping force and further consume seismic energy, and achieve the shock absorption effect. In each vibration stroke (two strokes for one vibration), the liquid pressure between each damping damper 431 and the corresponding regulating damper 443 alternately increases and decreases. Note that the vibration of conventional intensity is not sufficient to rotate damping flapper 431 to the position of contact with paddle 441, nor is it sufficient to open check valve 446 or oscillate damping flapper 431.

If the vibration amplitude is large but the frequency is not large, the check valve 446 will not open. In each vibration stroke, one of the damping baffles 431 is rotated to be in contact with the corresponding dial 441 to swing, thereby reducing a gap with the housing 460, so that a passage through which the damping liquid flows is narrowed and the damping capacity is enhanced.

When the frequency of the vibration in one direction is high, as shown in fig. 7, taking the clockwise rotation of the transmission shaft 410 as an example, the impact force of the liquid between the lower damping baffle 431 and the downstream adjusting baffle 443 in the clockwise direction is high, so that the corresponding one-way valve 446 is opened, a part of the damping liquid enters the liquid storage cavity 444 from the one-way valve 446 on the adjusting baffle 443, the sealing slider 445 moves in the clockwise direction, because the damping adjusting member 440 on the side cannot rotate clockwise, the other damping adjusting member 440 opposite to the one damping adjusting member 440 rotates clockwise, the corresponding damping baffle 431 rotates clockwise through the shifting block 441 thereof, the gap between the upper damping baffle 431 and the housing 460 is reduced, and the damping capacity is increased. When the vibration is in the other direction, the direction is opposite to the process, and the description is omitted. When the vibrations are perfectly symmetrical, the two damper flaps 431 rotate by substantially the same angle.

If the vibration is not completely symmetrical, as shown in fig. 8, after the vibration, the amplitude of clockwise rotation of the damping mount 431 located at the upper side when the driving shaft 410 rotates clockwise is greater than the amplitude of counterclockwise rotation of the damping mount 431 located at the lower side when the driving shaft 410 rotates counterclockwise. Under the same vibration condition, the effective area of the damping baffle 431 on the upper side for pushing the damping liquid is larger, the probability that the corresponding one-way valve 446 is opened is increased, so that the quantity of the liquid in the corresponding chambers of the two liquid storage chambers 444 is basically consistent, and the damping baffle 431 on the lower side is easier to rotate anticlockwise, so that the sizes of gaps at the positions of the two damping baffles 431 are basically consistent, the symmetry of the damping effect is further ensured, and the device is not easy to generate side rollover due to the non-uniformity of vibration.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
