Moreover, it is difficult to adjust the softness and hardness of the shock absorbers by other means, and the adjustment means are relatively single. Therefore, a nitrogen shock absorption structure is urgently needed. Content of the Utility Model

Detailed Embodiment
[0022] Next, the technical solutions in the present utility model will be clearly and completely described in conjunction with the drawings. Only the preferred embodiments in the description are taken as examples. All other embodiments obtained by those skilled in the art without making creative efforts fall within the protection scope of the present utility model.
[0023] As Figures 1-4As shown in the figure, the following technical solution is adopted in this specific embodiment: It includes a piston column 1, an oil storage cylinder 2, and a first piston 3. The two piston columns 1 are respectively fixedly arranged on the opposite side walls of a platform 4 and a support frame 5 through bolts. An oil storage cylinder 2 is suspended between the platform 4 and the support frame 5. The first pistons 3 are movably arranged on both the upper and lower sides inside the oil storage cylinder 2, and the first pistons 3 are connected to one end of the piston columns 1. Guide rods 16 are fixedly arranged at the four corners of the lower part of the platform 4, and the guide rods 16 are movably inserted into the support frame 5. The guide rods 16 can provide guidance for the up and down movement of the platform 4, making the platform 4 more stable;
[0024] It further includes:
[0025] A nitrogen tank 6, the nitrogen tank 6 is fixedly arranged through penetration on the front side of the oil storage cylinder 2. A second piston 17 is movably arranged inside the nitrogen tank 6. Connecting frames 7 are respectively fixedly arranged on the left and right sides of the oil storage cylinder 2 through bolts. A cylindrical oil groove 8 opened inside the connecting frame 7 is communicated with the oil storage cylinder 2;
[0026] Moving blocks 9, there are two moving blocks 9, which are respectively movably arranged in the moving grooves 10 opened on the two connecting frames 7. A soft and hard adjustment mechanism 11 is arranged on the connecting frame 7;
[0027] Connecting rods 12, there are two connecting rods 12, which are respectively fixedly arranged on the front and rear side walls of the moving blocks 9 through bolts. Two connecting rods 13 are rotatably sleeved on the connecting rods 12 through bearings. The other ends of the two connecting rods 13 are respectively hinged to the platform 4 and the support frame 5. Reinforcing ribs 15 are arranged on the side walls of the connecting rods 13. The reinforcing ribs 15 can improve the structural strength of the connecting rods 13, so that the force-bearing performance of the connecting rods 13 is improved;
[0028] The soft and hard adjustment mechanism 11 includes:
[0029] A third piston 11-1, the third piston 11-1 is movably arranged in the cylindrical oil groove 8. A piston rod 11-2 is arranged on the third piston 11-1, and the piston rod 11-2 is movably arranged inside the connecting frame 7;
[0030] A threaded rod 11-3, the threaded rod 11-3 is rotatably penetrated through the moving block 9 through threads. A rubber pad 14 is fixedly arranged at one end of the threaded rod 11-3 through adhesion, and the rubber pad 14 abuts against one end of the piston rod 11-2. The rubber pad 14 can generate a large frictional force with one end of the piston rod 11-2 to prevent the threaded rod 11-3 from rotating under the influence of vibration during the shock absorption process, resulting in the rubber pad 14 being separated from the piston rod 11-2. The other end of the threaded rod 11-3 passes through the connecting frame 7 and is fixedly provided with an adjustment handle 11-4.
[0031] When using the utility model, an appropriate amount of nitrogen is injected into the nitrogen tank 6, and the nitrogen pressure in the nitrogen tank 6 is adjusted. When the platform 4 moves up and down due to vibration, the piston columns 1 on both sides move synchronously in opposite directions. Through the movement of the first piston 3 and the second piston 17, and the cooperation of the nitrogen pressure in the nitrogen tank 6, the hydraulic oil can flow reciprocally between the oil storage cylinder 2 and the nitrogen tank 6, forming a damping force and also realizing the shock absorption of the platform 4. During this process, affected by the connecting rod 13, the movable block 9 can reciprocally move in the movable groove 10. The movable block 9 drives the threaded rod 11-3 to reciprocally move left and right. The threaded rod 11-3 drives the third piston 11-1 to reciprocally move left and right through the piston rod 11-2. When the hydraulic oil in the oil storage cylinder 2 flows into the nitrogen tank 6, the third piston 11-1 can also push the hydraulic oil in the cylindrical oil groove 8 into the oil storage cylinder 2, increasing the compression amount of the nitrogen in the nitrogen tank 6. When the adjusting knob 11-4 is rotated to make the threaded rod 11-3 drive the rubber pad 14 to disengage from the piston rod 11-2 and move to the inside of the movable block 9, the reciprocating movement of the movable block 9 and the threaded rod 11-3 will not push the piston rod 11-2, so that the hydraulic oil in the cylindrical oil groove 8 and the oil storage cylinder 2 will not flow reciprocally during the shock absorption process, thus realizing a large-span adjustment of the shock absorption softness and hardness of the shock absorption structure.
[0032] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0033] 1. Through the cooperation of the support frame 5, the nitrogen tank 6, the connecting frame 7, the movable block 9, the connecting rod 12 and the connecting rod 13, the support and shock absorption of the platform 4 can have high stability;
[0034] 2. Through the cooperation of the soft and hard adjustment mechanism 11, means other than adjusting the nitrogen pressure can be used according to the usage requirements to realize a large-span adjustment of the shock absorption softness and hardness of the shock absorption mechanism.
[0035] For those skilled in the art, they can modify the technical solutions recorded in the foregoing embodiments and perform equivalent replacements of some technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
