Abstract
The utility model provides a gas spring which comprises a piston rod and a cylinder body. A heat shrinking tube wraps the outer surface of the cylinder body. The surface of the gas spring is easy to process, pollution problems caused by discharging do not exist, and the gas spring is low in cost, convenient to operate and strong in practicability.
Description
Technical field
The utility model relates to a kind of air spring, is specifically related to a kind of employing heat-shrink tube (thermal contraction casing tube) and carries out the air spring that the coating of cylinder body (air spring cylinder barrel) surface is processed.
Background technique
air spring is a kind of widely used elasticity original paper, its cylinder surface all will be carried out application (plastic-blasting, baking vanish, electrophoretic paint, wait surface treatment from the swimming paint) or electroplate (zinc-plated, the surface treatments such as chromium plating) etc. process for treating surface reaches corrosion proof function and specious function, above-mentioned processing method all will be passed through (the degreasing of multiple tracks pretreatment procedure, rust cleaning, phosphatization etc.) and finally be coated with, the plating operation is completed, and relate to the environment protection emission problem, and surface treatment quality (particularly decay resistance) is controlled closely related with each procedure, equipment investment is large, to operator require high.
Summary of the invention
The purpose of this utility model is the defect that exists in prior art in order to solve, and provides that a kind of surface treatment is simple, the air spring of less investment.
In order to achieve the above object, the utility model provides a kind of air spring, comprises piston rod and cylinder body; Outer surface of cylinder block is coated with heat-shrink tube.
Further improvement of the utility model is: large 1 ~ 3 millimeter than cylinder body external diameter of the internal diameter of above-mentioned heat-shrink tube; Long 1 ~ 3 millimeter of Length Ratio cylinder body.
Heat-shrink tube adopts PVC or PET.
The utility model has the following advantages compared to existing technology: the characteristics of utilizing the heat-shrink tube heat to shrink, heat during use, and the heat-shrink tube retraction tightly is coated on the air spring cylinder surface, thereby realizes the surface treatment to cylinder body.The utility model air spring surface treatment simple (heating gets final product), without discharging the pollution problem that causes, and cost is low, and is easy to operate, practical.
Description of drawings
Fig. 1 is the structural representation of the utility model air spring;
Fig. 2 is the structural representation after the heating of the utility model air spring.
In figure, 1-piston rod, 2-cylinder body, 3-heat-shrink tube.
Embodiment
Below in conjunction with accompanying drawing, the utility model air spring is elaborated.
As shown in Figure 1, the utility model air spring comprises piston rod 1 and cylinder body 2.The outer surface of cylinder body 2 coats heat-shrink tube 3, heat-shrink tube 3 can adopt the PVC(PVC＝polyvinyl chloride), the PET(PETG) etc. various material, large 1 ~ 3 millimeter than cylinder body 2 outside dimensions of internal diameter size selection, both facilitated and put heat-shrink tube 3 on cylinder body 2, and can make again heat-shrink tube 3 tightly be coated on the surface of cylinder body 2 owing to replying elastomeric state after heating.The length of heat-shrink tube 3 is selected than long 1 ~ 3 millimeter of cylinder body 2 length.
During coating, can directly customize the heat-shrink tube 3 of required internal diameter size and length according to the size of cylinder body 2, the biscuit of perhaps directly selecting manufacturer to provide, adopt the corresponding length of computer heat shrinkable tube cutter cutting to prepare heat-shrink tube 3.(even not wiping is wiped clean on cylinder body 2 surfaces, there is oil also can not affect coating), then put heat-shrink tube 3, but then put into baking oven or the drying tunnel heating of setting temperature, heating-up temperature is fixed according to material and the heating time of heat-shrink tube 3 used, general temperature is high, heating time short (determining after concrete examination bag), after heating, heat-shrink tube 3 is replied elastomeric state, but at this moment load has not had, will shrink shaping and tightly be coated on the surface of cylinder body 2, thereby complete whole treatment process process.
The utility model air spring is simple in structure, and process of surface treatment is simple, only need to carry out heat treated to get final product less demanding, practical to operator.
