Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorbers, and in particular relates to a nitrogen shock absorber. Background Art

[0002] Shock absorbers are used to suppress the vibration caused by the rebound of the spring after absorbing shock and the impact from the road. They are widely used in automobiles to accelerate the attenuation of frame and body vibrations to improve the driving smoothness of the car. When passing through uneven roads, although the shock-absorbing spring can filter out the vibration of the road, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump.

[0003] However, there are some problems with the prior art: for similar nitrogen shock absorbers on the market, the adjustment knobs are not located within the user's adjustment line of sight after the shock absorbers are installed. When the shock absorbers need to be adjusted, users cannot accurately know the specific scale of their adjustments, resulting in different hardnesses of the four shock absorbers of the vehicle, which leads to unstable vehicle driving and poor driving comfort. More seriously, the vehicle is bumpy and easily causes accidents, and the user experience is not good. Therefore, we propose a nitrogen shock absorber. Utility Model Content

[0025] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 5As shown, a nitrogen shock absorber provided by an embodiment of the utility model includes a connecting device 1, one end of the connecting device 1 is detachably connected to a shock absorber body 2, and the other end of the connecting device 1 is detachably connected to an oil-gas separator 6, the oil-gas separator 6 is responsible for transmitting oil pressure and air pressure to the shock absorber body 2 so that the internal pressure of the shock absorber body 2 is balanced to achieve a shock absorbing effect, a second connecting member 5 is provided at the lower end of the connecting device 1, and the second connecting member 5 is used to connect to the car body, when encountering a bumpy road section, the car is pressed down to transmit inertia to the piston rod 3, and then the piston rod 3 is pressed down to the inside of the shock absorber body 2 to transmit the force, so that the car body can reduce the discomfort caused by the bump.

[0027] An adjustment component 7 is provided on one side of the connecting device 1. The adjustment component 7 is located on the side of the connecting device 1 close to the tire, so that the user can clearly see the adjustment number of the shock absorber body 2 during adjustment. This is more conducive to the user adjusting the softness and hardness of the four shock absorber bodies 2 to the same state, so that the car body runs smoothly and the driving comfort is guaranteed. The position of the adjustment component 7 also makes the shock absorber body 2 more beautiful and cool, so that the product is effectively combined in terms of appearance, ease of use and diverse functions.

[0028] An oil inlet hole 11 is opened on the side wall of the connecting device 1, and a cavity 12 is formed inside the connecting device 1 for oil and gas cooperation with the shock absorber body 2. Oil is transported to the cavity 12 through the oil inlet hole 11, thereby forming oil and gas pressure cooperation, so that the shock absorber body 2 can achieve a better shock absorption effect.

[0029] The cavity 12 is communicated with the oil inlet hole 11, and the adjustment component 7 includes an adjustment knob 701 and a shutoff damping plug 703.

One end of the fine-tuning core rod 702 is rotatably connected to a shutoff regulating valve core 705, and a shutoff regulating core rod 707 is arranged on one side of the shutoff regulating valve core 705. When it is necessary to adjust the shock absorber body 2, first rotate the adjustment knob 701, and then drive the fine-tuning core rod 702 to rotate. When the fine-tuning core rod 702 rotates, it will drive the shutoff regulating valve core 705 to rotate. At this time, the shutoff regulating valve core 705 drives the shutoff regulating core rod 707 to rotate, and the shutoff regulating core rod 707 drives the lower component to rotate. Under the linkage of each component, the hardness of the shock absorber body 2 is adjusted.

[0030] A circular hole 15 is opened on one side of the connecting device 1, and a gear plate 8 is arranged on one side of the connecting device 1. The gear plate 8 has an eight-stage adjustment function, which is more accurate than the traditional twenty-plus stages. The eight-stage adjustment allows the user to adjust the gear more intuitively. The adjustment component 7 passes through the center end of the gear plate 8 and is arranged in the circular hole 15, and the circular hole 15 is communicated with the oil inlet hole 11, so that the adjustment component 7 can adjust the hardness of the shock absorber body 2.

[0033] A first connecting hole 9 is provided at one end of the connecting device 1, and a second connecting hole 10 is provided at the other end of the connecting device 1. A through hole is provided at the bottom end of the second connecting hole 10, and the through hole is communicated with the circular hole 15. The lower end of the shock absorber body 2 is threadedly connected to the first connecting hole 9, and the lower end of the oil-gas separator 6 is threadedly connected to the second connecting hole 10.
