Abstract
The utility model discloses a cylinder body type spring shock absorber which is used for overcoming the defect that an existing spring shock absorber is easy to abrade and corrode. The cylinder body type spring shock absorber comprises a cylinder body, an end cover, a piston and a piston rod, the upper end of the cylinder body is connected with the end cover, a suspension ring is arranged at the lower end of the cylinder body, the piston is arranged in the cylinder body and matched with the cylinder body, the piston rod penetrates through the end cover and is connected with the piston, at least one spring is arranged at the lower end of the piston, one end of the spring is connected with the piston, and the other end of the spring is connected with the bottom of the cylinder body. The cylinder body type spring shock absorber has the advantages of being capable of preventing the spring from being abraded and corroded, and long in service life.
Description
Technical field
The utility model relates to a kind of vibration damper, relates in particular to a kind of barrel-type spring damper.
Background technique
Vibration damper be mainly used to suppress between the link concussion and from the impact of external force.Common are rubber absorbers, butterfly spring vibration damper, flexible cantilever beam vibration damper and helical spring shock absorber, have a wide range of applications.Helical spring shock absorber particularly, because of its low cost of manufacture, good damping effect and use very extensively.
Application number is that 201020168845.9 Chinese utility model patent discloses a kind of Double-spring shock absorber, comprise piston rod, one end activity is plugged in the piston rod, the stiffening rib that the other end is overhanging, be installed in the lower union joint of piston-rod lower end and the connecting head of stiffening rib upper end, be enclosed within the cushion collar on the stiffening rib, be enclosed within the gear cover of movable match middle-end, the gear button, place kick spring and reinforcement spring between gear cover and the upper binding head, it is characterized in that gear cover lower end is provided with shift slot, the gear button swings selects gear, and then the gear cover moves up and down the active force that changes kick spring and reinforcement spring.
This spring damper is because spring is exposed in the external environment, easily wearing and tearing, in case the corrosion-resistant coating of spring outside be worn, corrosion that just can acceleration spring, thus shortened working life of vibration damper.
The model utility content
The utility model causes vibration damper short problem in working life for the existing easy abrasion and corrosion of spring damper, and a kind of barrel-type spring damper is provided.
For addressing the above problem, the technological scheme that the utility model adopts is as follows:
A kind of barrel-type spring damper is characterized in that: comprise cylindrical shell, end cap, piston and piston rod; Described cylindrical shell upper end connects end cap, and the lower end is provided with suspension ring; Described piston is located in the cylindrical shell, and cooperates with cylindrical shell; Described piston rod passes end cap and is connected with piston, and described piston lower end is provided with at least one spring, and described spring one end is connected with piston, and the other end is connected with cylinder body bottom.
Further, described end cap and cylindrical shell are by being welded together.
Further, described piston rod and piston are threaded connection.
Further, be provided with the guide holder that leads for piston rod in the described cylindrical shell.
Compared with prior art, the utlity model has following beneficial effect:
One, the utility model is arranged on spring in the cylindrical shell, and spring one end is connected with the piston lower end, and an end is connected with cylinder body bottom, and piston is connected with piston rod, reaches the effect of damping.Simultaneously, avoid spring to place external environment, avoided spring to be worn and corrode, increased the working life of vibration damper.
Two, the utility model piston rod and piston are threaded connection, and it is low to have processing cost, mount and dismount easily characteristics.
Three, the utility model is provided with guide holder in cylindrical shell, and the wearing and tearing in less piston and the cylindrical shell are so that the utlity model has the characteristics of long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Mark among the figure: 1 is piston rod, and 2 is end cap, and 3 is guide holder, and 4 is cylindrical shell, and 5 is piston, and 6 is spring, and 7 is suspension ring.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Barrel-type spring damper of the present utility model comprises cylindrical shell 4, end cap 2, piston 5 and piston rod 1; Cylindrical shell 4 upper ends connect end cap 2, and the lower end is provided with suspension ring 7; Piston 5 is located in the cylindrical shell 4, and cooperates with cylindrical shell 4; Piston rod 1 passes end cap 2 and is connected with piston 5, and piston 5 lower ends are provided with at least one spring 6, and spring 6 one ends are connected with piston 5, and the other end is connected with cylindrical shell 4 bottoms.Preferably, end cap 2 and cylindrical shell 4 are by being welded together; Piston rod 1 is threaded connection with piston 5, makes things convenient for manufacturing, and installation and removal are convenient simultaneously.Be provided with the guide holder 3 for piston rod 1 guiding in the cylindrical shell 4, reduce the wearing and tearing between piston 5 and the cylindrical shell 4, improve working life of the present utility model.
