[0030] As Figures 1 to 6 Indicated, an anti-shock high-pressure box in an embodiment of the utility model, comprising: high pressure box 1, separate type limiting assembly 2, combined anti-shock assembly 3.

[0031] As Figures 1 to 2 Indicated, separate type limiting assembly 2 is assembled below high pressure box 1, and separate type limiting assembly 2 includes anti-shock box seat 201, and anti-shock box seat 201 is arranged below high pressure box 1.Anti-shock box seat 201 plays the role of assembly limiting to elastic supporting pad 202, fixed bottom plate 203, and simultaneously, can support and limit high pressure box 1.

[0032] As Figures 1 to 2 Indicated, anti-shock box seat 201 is integrally formed with inner partition plate 204, and inner partition plate 204 is arranged below elastic supporting pad 202.Inner partition plate 204 plays the role of supporting and limiting to elastic supporting pad 202.

[0033] As Figures 1 to 2As shown, the elastic supporting pad 202 is fixedly assembled in the anti-vibration box seat 201. The bottom surface and the side surface of the fixed bottom plate 203 are protected against vibration by the elastic supporting pad 202.

[0034] Preferably, the cross section of the elastic supporting pad 202 is L-shaped. This facilitates the assembly, limiting and shock absorption assistance of the elastic supporting pad 202 to the bottom surface and the side surface of the fixed bottom plate 203.

[0035] As shown in the figure, Figures 1 to 2 The elastic supporting pad 202 and the high-pressure box 1 are arranged with a fixed bottom plate 203. The high-pressure box 1 is supported and limited by the fixed bottom plate 203.

[0036] As shown in the figure, Figure 6 The upper side of the fixed bottom plate 203 is fixedly assembled with a plurality of uniformly distributed fixed blocks 205, and the plurality of fixed blocks 205 are sleeved on the outer side of the high-pressure box 1. The high-pressure box 1 is fixedly assembled by the plurality of fixed blocks 205.

[0037] As shown in the figure, Figure 6 The outer side of the anti-vibration box seat 201 is fixedly connected with a plurality of uniformly distributed exhaust plates 206, the plurality of exhaust plates 206 are arranged corresponding to the buffer oil cylinder 302, and a plurality of uniformly distributed air holes are formed in the plurality of exhaust plates 206. The exhaust plate 206 plays a role of exhausting and dissipating heat for the anti-vibration box seat 201, reduces the accumulation of heat in the anti-vibration box seat 201, and ensures the stability of the compression piston plate 303 and the hydraulic buffer oil interacting with the fixed bottom plate 203.

[0038] As shown in the figure, Figures 1 to 4 The combined anti-vibration assembly 3 is assembled between the fixed bottom plate 203 and the high-pressure box 1, and the combined anti-vibration assembly 3 includes an anti-vibration air bag 301 arranged between the fixed bottom plate 203 and the high-pressure box 1. The anti-vibration air bag 301 plays a role of supporting, limiting and protecting the fixed bottom plate 203.

[0039] As shown in the figure, Figures 3 to 4 The anti-vibration air bag 301 is arranged with a supporting spring 306. The supporting spring 306 is contracted and reset to support and reset the anti-vibration air bag 301.

[0040] Among them, the outer side of the anti-vibration air bag 301 is provided with a plurality of uniformly distributed damping exhaust holes. The air in the anti-vibration air bag 301 is discharged through the damping exhaust holes, so as to facilitate the shock absorption and limiting of the fixed bottom plate 203 through the exhaust contraction and air intake reset state of the anti-vibration air bag 301.

[0041] Specifically, the damping exhaust hole is located in the anti-seismic air bag 301, and the diameter of one end is larger than that of the other end. It is convenient for the air in the anti-seismic air bag 301 to be exhausted at a rate greater than the intake rate under the action of the damping exhaust hole, so as to facilitate the buffering and limiting of the anti-seismic air bag 301 to the fixed bottom plate 203 by controlling the reset state of the anti-seismic air bag 301.

[0042] As shown in Figures 1 to 2 , the outer side of the anti-seismic air bag 301 is provided with a plurality of groups of uniformly distributed buffer oil cylinders 302.

[0043] Among them, the buffer oil cylinder 302 is filled with hydraulic buffer oil. The vibration suffered by the compression piston plate 303 is converted into the internal energy of the hydraulic buffer oil by the circulation of the hydraulic buffer oil on both sides of the compression piston plate 303, so as to facilitate the shock absorption of the fixed bottom plate 203.

[0044] As shown in Figures 1 to 2 , a plurality of compression piston plates 303 are slidably assembled in the plurality of buffer oil cylinders 302. The compression piston plate 303 supports and limits the piston rod 304, and the piston rod 304 can support and limit the fixed bottom plate 203 by limiting the vibration of the compression piston plate 303.

[0045] Preferably, the compression piston plate 303 is provided with a tapered oil return hole on both sides, and the diameter of the tapered oil return hole close to one end of the high-pressure box 1 is smaller than that of the other end. It is convenient to control the conduction state of the tapered oil return hole by moving the oil return sealing ball 307 in the tapered oil return hole.

[0046] As shown in Figures 1 to 2 , a plurality of tapered oil return holes are provided with an oil return sealing ball 307. The conduction state of the tapered oil return hole is controlled by the movement of the oil return sealing ball 307. The end of the plurality of tapered oil return holes away from the high-pressure box 1 is fixedly connected with the anti-dropping net 308. The anti-dropping net 308 limits the movement of the oil return sealing ball 307, which reduces the possibility of the oil return sealing ball 307 falling out of the tapered oil return hole.

[0047] As shown in Figures 1 to 2 , the compression piston plate 303 is fixedly connected with the piston rod 304, and the piston rod 304 is fixedly connected with the fixed bottom plate 203. The fixed bottom plate 203 and the compression piston plate 303 are connected and fixed by the piston rod 304.

[0048] As shown in Figures 1 to 2 , the compression piston plate 303 and the buffer oil cylinder 302 are provided with a reset spring 305. The compression piston plate 303 is supported and limited by the contraction and reset of the reset spring 305.

[0049] Specifically, the compression piston plate 303 is provided with a tapered oil inlet hole, which is arranged between a plurality of tapered oil return holes and has a larger diameter at one end of the high-pressure box 1 than at the other end. The conduction state of the tapered oil inlet hole is controlled by the sliding of the oil inlet sealing ball 309 in the tapered oil inlet hole.

[0050] Preferably, the tapered oil inlet hole has a larger diameter at the end away from the high-pressure box 1 than at the end close to the high-pressure box 1. This allows the compression piston plate 303 to have a larger oil inlet speed than oil return speed during movement, thereby facilitating damping and limiting the compression piston plate 303.

[0051] The piston rod 304 is provided with a flow guide oil channel, and the outer side of the piston rod 304 is provided with a pair of oil discharge holes that are connected to the tapered oil inlet hole through the flow guide oil channel. The hydraulic buffer oil delivered by the tapered oil inlet hole is guided out through the cooperation of the flow guide oil channel and the oil discharge hole.

[0052] As shown in Figures 1 to 2 The tapered oil inlet hole is provided with an oil inlet sealing ball 309 arranged therein. The oil inlet sealing ball 309 controls the conduction state of the tapered oil inlet hole by moving in the tapered oil inlet hole. The side of the tapered oil inlet hole close to the high-pressure box 1 is provided with a limiting net 310. The limiting net 310 prevents the oil inlet sealing ball 309 from falling out.

[0053] In use, the high-pressure box 1 can be placed above the fixed bottom plate 203, and the high-pressure box 1 can be assembled and limited by assembling and fixing a plurality of fixed blocks 205. In actual application, the bottom and side surfaces of the fixed bottom plate 203 are limited by the elastic supporting pad 202.

[0054] At the same time, when the high-pressure box 1 is subjected to external force and vibrates, the fixed bottom plate 203 can drive the piston rod 304 to compress the compression piston plate 303 under the gravity of the high-pressure box 1. When the compression piston plate 303 compresses the return spring 305, the oil return sealing ball 307 blocks the tapered oil return hole under the action of the hydraulic buffer oil, and the oil inlet sealing ball 309 can move in the tapered oil inlet hole at the same time. At this time, the tapered oil return hole is closed and the tapered oil inlet hole is open, and the hydraulic buffer oil in the buffer cylinder 302 is delivered to the upper side of the compression piston plate 303 along the tapered oil inlet hole, the flow guide oil channel, and the oil discharge hole.

[0055] When the compression piston plate 303 is reset under the action of the reset spring 305, the oil return sealing ball 307 moves in the tapered oil return hole under the action of the hydraulic buffer oil, and the oil inlet sealing ball 309 can be synchronized to move in the tapered oil inlet hole, at this time, the tapered oil return hole is communicated and the tapered oil inlet hole is closed, the hydraulic buffer oil above the compression piston plate 303 can be returned to the lower side of the compression piston plate 303 along the tapered oil return hole. Since the diameter of the tapered oil inlet hole away from one end of the high-pressure tank 1 is larger than the diameter of the tapered oil return hole close to one end of the high-pressure tank 1, the oil inlet speed is greater than the oil return speed during the movement of the compression piston plate 303, thereby facilitating the damping and limiting of the compression piston plate 303, and the anti-vibration air bag 301 and the multiple groups of piston rods 304 are matched to support the fixed bottom plate 203, thereby improving the anti-vibration performance of the high-pressure tank 1.

[0056] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all aspects as illustrative and not restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended to embrace all changes falling within the meaning and range of equivalents of the elements of the claims.
