Embodiment
With reference to shown in Fig. 2, a kind of air-pressure damping mechanism of the present embodiment, including handle pipe 2 and the piston rod in handle pipe 2
5, the two ends of handle pipe 2 sealing, handle pipe 2 is interior filled with gas, and the gas can be air, or mixed gas, piston rod 5 is located at
One end in handle pipe 2 is provided with damping piston 6, and 2 points by handle pipe of the damping piston 6 is A chambers and B chambers, and A chambers are rodless cavity, and B chambers are to have
Rod cavity, the structure is similar to air cylinder structure, and difference is, handle pipe 2 is sealing space, and damping piston 6 has good gas
Body damping action；Specifically, damping piston 6, which is provided with sealing ring mounting groove, sealing ring mounting groove, is provided with floating seal ring 63,
The size of the sealing ring mounting groove is suitably larger than floating seal ring 63, floating seal ring 63 is had certain floating space, should
Floating seal ring 63 is "O"-ring, be communicated with damping piston 6 A chambers and sealing ring mounting groove the first damping hole 62 and
B chambers and the second damping hole 64 of sealing ring mounting groove are connected, the aperture of the first damping hole 62 is more than the aperture of the second damping hole 64,
The gap 65 for connecting B chambers and sealing ring mounting groove is additionally provided between damping piston 6 and handle pipe 2, i.e., damping piston 6 is close to B chambers
Diameter is less than diameter of the damping piston 6 close to A chambers, and damping piston 6 is slightly less than the internal diameter of handle pipe 2, gap close to the diameter of A chambers
65 can allow gas to circulate.The concrete operating principle of damping piston 6 is described as follows：
When handle pipe 2 is moved relative to piston rod 5, the gas of A chambers and B intracavitary is damped by the first damping hole 62, second
Hole 64 and gap 65 form damping action, specifically, when A chambers compresss, in the case where gas pressure is acted on, and floating seal ring 63 is to A
Cavity direction floats (shown in such as Fig. 2 (a)), gap 65 is opened, A intracavity gas are by the first damping hole 62 through the He of the second damping hole 64
Gap 65 enters B chambers, forms air damping effect；When B chambers compress, floating seal ring 63 gas pressure effect under formed to
The trend that B cavity directions float, floats in the middle of sealing ring mounting groove, (shown in such as Fig. 2 (b)), and B intracavity gas are by gap 65 and second
Damping hole 64 enters A chambers through the first damping hole 62, forms air damping effect.Therefore, moved in handle pipe 2 relative to piston rod 5
When, obvious damping action can be produced, and damping depends on the chi of the first damping hole 62, the second damping hole 64 and gap 65
The gas circulation of very little size, wherein gap 65 is more than the gas circulation of the first damping hole 62, the gas of the first damping hole 62
Circulation is more than the gas circulation of the second damping hole 64, and floating seal ring 63 can play air-flow adjustment effect, gas is circulated
More stablize, using damping action of the gas medium in the damping hole of damping piston 6, the resistance of gas medium can be greatly improved
Buddhist nun's power, and the impulsive force of A chambers compression is bigger, damping is better, makes the damping effect of gas medium more excellent.
In addition, being additionally provided with damping piston 6 in the present embodiment in guide ring mounting groove, guide ring mounting groove provided with being oriented to
Ring 61, guide ring 61 plays good supporting and guide effect to damping piston 6, protects damping piston 6 and handle pipe 2 not to be damaged
It is bad.First damping hole 62 passes through guide ring 61, and guide ring 61 passes through spring finger setting, it is to avoid the movement dislocation of guide ring 61, blocks up
Fill in the first damping hole 62.

Sleeve pipe 1, handle pipe 2 and piston rod 5, the bottom of sleeve pipe 1 are provided with the mounting hole for being used for connecting wheel shaft, and top is hatch frame, and handle pipe 2 is set
In in sleeve pipe 1, the outer diameter of handle pipe 2 is slightly less than the inner diameter of sleeve pipe 1, handle pipe 2 is in slide fit state with sleeve pipe 1, no
It is also easy to produce and rocks, and one end that handle pipe 2 is engaged with sleeve pipe 1 is provided with handle pipe piston 3, handle pipe piston 3 forms close with the bottom of sleeve pipe 1
The C chambers of envelope, C intracavitary is filled with gas；Piston rod 5 passes through handle pipe piston 3, and is tightly connected between the two, and one end of piston rod 5 leads to
Cross and hang tight screw 7 and be fixed on the bottom of sleeve pipe 1, and provided with seal ring seal, the other end is provided with the damping piston being engaged with handle pipe 2
6, the damping piston 6 has the damping pore structure of above-mentioned air-pressure damping mechanism.When handle pipe 2 is pushed, A chambers and C cavity spaces subtract
It is small, gas compression；B cavity spaces increase, and gas pressure reduces, and now floating seal ring 63 floats, i.e., floated to A cavity directions, will
Gap 65 is opened, and A chambers gas enters B chambers by the first damping hole 62 through the second damping hole 64 and the two-way of gap 65, produces lower pressure drag
Buddhist nun's power, and the impact strength that handle pipe 2 is pushed is bigger, damping is better；When handle 2 resilience of pipe, B cavity spaces reduce, gas pressure
Contract, now floating seal ring 63 forms the trend floated downward under gas pressure effect, i.e., floated to B cavity directions, float on sealing ring
In the middle of mounting groove, force B chambers gas to enter A chambers through the first damping hole 62 by the damping hole 64 of gap 65 and second, produce resilience resistance
Buddhist nun's power, in the process, because the aperture of the second damping hole 64 is smaller, therefore, gas is mainly circulated by gap 65.
A kind of air-pressure damping damper of the present embodiment, using A chambers, three cavity body structures of B chambers and C chambers, wherein any one
Gas leakage occurs for individual cavity, can the resilience of support shank pipe 2, it is smaller to damper integral shock-absorbing influential effect；Hindered using air pressure
