Abstract
The utility model relates to the technical fields of air-leg, especially a kind of dust-proof air-leg, including cylinder body, piston rod and piston, the piston is built in cylinder body, and described piston rod one end is connect with piston, and the piston base is equipped with elastic limit block, it connect with piston place on the piston rod and is arranged with dustband, the cylinder body top inner side is equipped with when piston rod movement and while driving dustband to move to cylinder body top accommodates the cavity of dustband.The dustband is " O " type elastomeric wiper.The utility model is equipped with block and dustband, either air-leg working condition or closed state on the piston rod, can prevent dust from entering cylinder body well, influences the use in later period, and structure is simple, easy to operate.
Description
Technical field
The utility model relates to the technical field of air-leg, especially a kind of dust-proof air-leg.
Background technique
Air-leg is common one of turnover device, be one kind can support, buffer, braking, height adjustment and angle tune
The industry accessories of the effects of section.Principle is that inert gas or gas mixture are filled in closed pressure cylinder, is made in cavity
Pressure be higher than several times or tens times of atmospheric pressure, be less than the cross-sectional area of piston using the cross-sectional area of piston rod to produce
Raw pressure difference realizes the movement of piston rod.But existing air-leg is either in work or in the state of closure, dust-proof
Effect is poor, and dust enters oil cylinder, leverages the using effect in its later period.
Utility model content
In order to overcome the shortcomings of existing technology, the utility model provides a kind of dust-proof air-leg.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of dust-proof air-leg, including cylinder body, it is living
Stopper rod and piston, the piston are built in cylinder body, and described piston rod one end is connect with piston, and the piston base is equipped with elasticity
Limited block, it is described stretch out cylinder body upper cover of piston rod be equipped with block, the block on the top of cylinder body, the piston rod with work
Plug connection place is arranged with dustband, and the cylinder body top inner side is equipped with when piston rod movement and dustband is driven to move to cylinder
The cavity of dustband is accommodated when body top.
It is " O " type elastomeric wiper that another embodiment according to the present utility model, which further comprises the dustband,.
The utility model has the beneficial effects that on the piston rod equipped with block and dustband, either air-leg work shape
State or closed state can prevent dust from entering cylinder body well, influence the use in later period, and structure is simple, easy to operate.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
1. cylinder body in figure, 2. piston rods, 3. pistons, 4. dustbands, 5. cavitys, 6. blocks, 7. elastic spacings
Block.
Specific embodiment
If Fig. 1 is the structural schematic diagram of the utility model, a kind of dust-proof air-leg, including cylinder body 1, piston rod 2 and piston
3, piston 3 is built in cylinder body 1, and 2 one end of piston rod is connect with piston 3, and 3 bottom of piston is equipped with elastic limit block 7, stretches out cylinder body
Block 6 is arranged on 1 piston rod 2, block 6 is arranged with dust-proof in place of connecting on the top of cylinder body 1, piston rod 2 with piston 3
Circle 4,1 top inner side of cylinder body, which is equipped with, accommodates dustband 4 when piston rod 2 moves and dustband 4 is driven to move to 1 top of cylinder body
Cavity 5.Preferably, dustband 4 is " O " type elastomeric wiper.
When not in use, when piston rod 2 does not move, above cylinder body 1, the block 6 on piston rod 2 just blocks the utility model
The opening of built-in piston 3 on cylinder body 1, avoids the entrance of dust.When piston rod 2 moves, piston rod 2 stretches out cylinder body 1, but moves
To the position of needs, it is dust-proof that dustband 4 is just contained in progress in cavity 5.3 bottom of piston is equipped with elastic limit block 7, prevents from living
When stopper rod 2 pushes, the collision between piston 3 and cylinder body influences the use of piston 3.
The utility model is equipped with block 7 and dustband 4 on piston rod 2, and either air-leg working condition is still closed
State can prevent dust from entering cylinder body well, influence the use in later period, and structure is simple, easy to operate.
