Abstract
The utility model relates to a spring sleeved in plastic tube, which is characterized in that a spring 1 is sheathed with a plastic pipe 2, and the both ports of the plastic pipe 2 are respectively sealed; the spring does not contact outside, and can not be corroded by liquid; the spring is particularly suitable for using in the device which is frequently contacted with corrosive liquid. The utility model has the advantages of simple structure, low cost, strong corrosion resistance, and long service life.
Description
The utility model is a kind of spring.
The device of corrosive liquids such as some water contacting, acid solution needs the installing spring, and is generally zinc-plated on the spring surface for preventing spring by liquid corrosion, chromium plating, because spring is done fore and aft motion, coating comes off through after a while, loses protective action,
The purpose of this utility model is that a kind of spring that can prevent liquid corrosion for a long time will be provided.
Solution of the present utility model is to be with plastic tube on existing spring, and closed at both ends has the space between plastic tube and the spring, and plastic tube can fatigue not be damaged during telescopic spring, and spring does not contact with liquid, can be by liquid corrosion.
Below in conjunction with accompanying drawing the utility model is specified:
Accompanying drawing is the utility model schematic representation.
Be with plastic tube 2 on spring 1,2 two ports of plastic tube are sealed respectively, be as the criterion not expose spring 1, the sealing of port adopts heat seal get final product, and plastic tube 2 produces and is out of shape when preventing that spring 1 is flexible, can have the space between spring 1 and the plastic tube 2.
The utility model is simple in structure, and cost is low, and corrosion resistance is strong.Long service life.
Claims (2)
1, a kind of spring that is with plastic tube is characterized in that: be with plastic tube 2 on spring 1,2 two ports of plastic tube are sealed respectively.
2, the spring that is with plastic tube according to claim 1 is characterized in that: have the space between spring 1 and the plastic tube 2.
