Abstract
The utility model discloses an oilless air compressor which comprises an air storage tank. A motor, a transmission mechanism, a cylinder and a pressure control switch are arranged on the air storage tank. Guide wheels which are used for moving are arranged on the lower side of the cylinder, and are fixed below the air storage tank through a damping device. The damping device comprises an upper base and a lower base. An extra heavy pipe and a tubule are arranged between the upper base and the lower base. The upper base is connected with the upper end of the extra heavy pipe. The lower base is connected with the lower end of the tubule. The upper end of the tubule is inserted in the extra heavy pipe in a penetrating mode. Springs are arranged on the extra heavy pipe and the tubule. The oilless air compressor is simple in structure, ingenious in design and capable of preventing parts on the compressor air storage tank from loosening and falling off, and has damping effect.
Description
Technical field
The utility model relates to the compressed air source unit field, particularly relates to a kind of oilless air compressor.
Background technique
Air compressor is the main body in the compressed air source unit, and it is the device that the mechanical energy of prime mover is converted to the gas pressure energy, is compressed-air actuated pressure generator.Patent application document such as Chinese application number 03221163. 5 discloses a kind of Novel non-oil air compressor, comprise motor, driving mechanism, cylinder block, pressure control switch, gas holder, piston rod and be located at polymer piston ring on the piston rod, it is characterized in that, in piston ring, be provided with auxiliary press ring, this pressure ring comprises that an outer ring is the reed of profile of tooth, be provided with the profile of tooth trim ring that cooperates with it in the reed, the profile of tooth trim ring is fixed on the piston rod.Although the oilless air compressor of this structure is provided with auxiliary press ring in piston ring, thereby reduce motor load, reduce energy consumption.But oilless air compressor can produce vibrations in work, can cause part above the air compressor air storage tank loose, come off.
In sum, for the defective of prior art, need especially a kind of oilless air compressor, thereby solve above-mentioned problem.
The model utility content
The technical problem that the utility model mainly solves provides a kind of oilless air compressor, can solve traditional air compressor, the large problem of vibratility.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of oilless air compressor is provided, comprise gas holder, gas holder is provided with motor, driving mechanism, cylinder and pressure control switch, be provided with below the described cylinder for mobile guide wheel, guide wheel is fixed on the below of gas holder by damping device, damping device comprises upper bed-plate and lower bottom base, be provided with extra heavy pipe and tubule between upper bed-plate and the lower bottom base, the upper end of extra heavy pipe is connected with upper bed-plate, the lower end of tubule is connected with lower bottom base, and intert in extra heavy pipe the upper end of tubule, and extra heavy pipe and tubule are provided with spring.When air compressor is vibrative, can pass to damping device by gas holder when work, because damping device is provided with spring, spring has certain buffer function, so just can reach certain damping effect.
In preferred embodiment of the utility model, also be provided with on the described gas holder for the handle that promotes.
In preferred embodiment of the utility model, the below of described gas holder also is provided with sewage draining exit.
The beneficial effects of the utility model are: the utility model is simple in structure, designs ingeniously, has damping effect, can prevent that the part above the air compressor air storage tank is loose, come off.
Description of drawings
Fig. 1 is the schematic representation of a kind of oilless air compressor of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of oilless air compressor described in the utility model, comprise gas holder 1, gas holder 1 is provided with motor 2, driving mechanism 3, cylinder 5 and pressure control switch 6, be provided with below the described cylinder 5 for mobile guide wheel 7, guide wheel 7 is fixed on the below of gas holder 1 by damping device, damping device comprises upper bed-plate 8 and lower bottom base 9, be provided with extra heavy pipe 11 and tubule 12 between upper bed-plate 8 and the lower bottom base 9, connection is connected in the upper end of extra heavy pipe 11 with upper bed-plate, the lower end of tubule 12 is connected with lower bottom base 9, and intert in extra heavy pipe 11 upper end of tubule 12, and extra heavy pipe 11 and tubule 12 are provided with spring 10.When air compressor is vibrative, can pass to damping device by gas holder when work, because damping device is provided with spring, spring has certain buffer function, so just can reach certain damping effect.Also be provided with on the gas holder 1 for the handle 13 that promotes.Just need not to adopt overhead traveling crane to lift by crane like this in mobile, the below of gas holder 1 also is provided with sewage draining exit 14.Like this service time of a specified duration some impurity in the gas holder can be discharged.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
