Abstract
The utility model discloses a kind of durable damping, including housing, telescopic rod, spring, sealing ring and locating part, the housing is hollow and one end is provided with opening and is inserted into for telescopic rod, the spring is placed on telescopic rod and spring mid diameter is more than both ends diameter, by plastic manufacturing, the sealing ring branch is sheathed on telescopic rod and positioned at the upper and lower ends of spring two sealing rings；The longer life expectancy of the utility model damping, spring mid diameter is more than the diameter of both ends of the spring, spring is set to be unlikely to deform after being compressed, so that the access times of spring are more, longer life expectancy, simultaneously because stress is more preferable when sealing ring by plastic manufacturing, makes the sealing ring movement be touched with spring interface, telescopic rod is set to be easier pull-out, and it is not easily to fall off, be hardly damaged, so as to improve the service life entirely damped.
Description
Technical field
Damping field is the utility model is related to, more particularly, to a kind of durable damping.
Background technology
Traditional damping, since its spring is in straight barrel type, has larger bounce, and use when being compressed the spring
Short life, is using certain number（Usually 5-6 ten thousand times）The situation for oil leak occur is easily deformed and caused afterwards, and is placed on bar
Sealing ring be rubber manufacture, making it, the stressing conditions when contacting are poor with spring, phenomena such as easily coming off, so as to reduce
Damp overall service life.
Utility model content
In view of the deficiencies of the prior art, the purpose of this utility model is to provide a kind of service life is longer, stress is more preferable
Damping.
To achieve the above object, scheme provided by the utility model is：A kind of durable damping, including housing, telescopic rod,
Spring, sealing ring and locating part, the housing is hollow and one end is provided with opening and is inserted into for telescopic rod, and the spring is placed on telescopic rod
Upper and spring mid diameter is more than both ends diameter, and two sealing rings are sheathed on telescopic rod by plastic manufacturing, the sealing ring branch
And positioned at the upper and lower ends of spring.
Further, a capping is cased with the telescopic rod, the capping, which is also embedded in shell end opening, to be used to incite somebody to action
Telescopic rod is fixed in housing.
Further, the telescopic rod end is provided with a groove and is used to be connected with locating part.
This programme has the beneficial effect that：The longer life expectancy of damping, spring mid diameter are more than the diameter of both ends of the spring, make bullet
Spring is unlikely to deform after being compressed, so that the access times of spring are more, longer life expectancy, simultaneously because sealing ring is by plastics system
Make, make sealing ring movement with spring interface touch when stress it is more preferable, make telescopic rod be easier pull-out, and it is not easily to fall off, be hardly damaged,
So as to improve the service life entirely damped.
Brief description of the drawings
Fig. 1 is the overall structure figure of the utility model.
Fig. 2 is the cut-away view of the utility model.
Wherein, 1 is housing, and 2 be telescopic rod, and 21 be groove, and 3 be spring, and 4 be sealing ring, and 5 be locating part.
Embodiment
With reference to specific embodiment, the utility model is described in further detail：
Referring to shown in attached drawing 1 to attached drawing 2, a kind of durable damping, including housing 1, telescopic rod 2, spring 3, sealing ring 4 with
Locating part 5, housing 1 is hollow and one end is provided with opening and is inserted into for telescopic rod 2（Housing 1 is cylindrical）, spring 3 is placed on telescopic rod 2
Upper and 3 mid diameter of spring is more than both ends diameter, and two sealing rings 4 are by plastic manufacturing（Sealing ring 4 is cirque structure）, sealing ring
4 branches are sheathed on telescopic rod 2 and positioned at the upper and lower ends of spring 3.
Wherein, a capping is cased with telescopic rod 2, it is open-ended upper for telescopic rod 2 to be fixed that capping is also embedded in housing 1
In in housing 1；2 end of telescopic rod is provided with a groove 21 and is used to be connected with locating part 5.
The embodiment of the above is only presently preferred embodiments of the present invention, and limit in any form is not done to the present invention
System.Any those skilled in the art, without departing from the scope of the technical proposal of the invention, all using the disclosure above
Technology contents more possible variations and retouching are made to technical solution of the present invention, or be revised as the equivalence enforcement of equivalent variations
Example.Therefore all contents without departing from technical solution of the present invention, the equivalent equivalence changes that the thinking according to the present invention is made, should all cover
In in protection scope of the present invention.
