For existing above mentioned problem, a kind of damper is now provided.
To achieve these goals, the technical scheme that the utility model is taken is：
A kind of damper, wherein, including：
One damper, the damper is the bar from head to afterbody, and the inside of the damper is along the damping
The centerline direction of device is through opening up through hole, and the head-tail two ends of the damper are welded；
The cross sectional shape of the damper includes the Part I, Part II, Part III, the Part IV that are sequentially connected
Constituted with five parts of Part V, the Part I is semicircle, the Part II is isosceles trapezoid, described second
The short side of isosceles trapezoid is divided to be overlapped with the semicircular diameter side of the Part I；The Part IV is isosceles trapezoid, described
Part V is semicircle, and the short side of the Part IV isosceles trapezoid overlaps with the semicircular diameter side of the Part V；
The Part III is rectangle, and the both sides short side of the Part III rectangle overlaps with half round diameter side respectively, described the
The both sides of three segment rectangles are long in long with the Part II isosceles trapezoid respectively and the Part IV isosceles trapezoid
Side long overlaps.
A kind of above-mentioned damper, wherein, the inside of the damper offer along the Part I, described second
Point, the through holes of outer contour shape that are formed of the Part III, the Part IV and the part of the Part V five.
A kind of above-mentioned damper, wherein, laser welding is passed through at the head-tail two ends flattening of the damper.
The utility model is as a result of above-mentioned technology, the good effect for being allowed to have compared with prior art：
(1) by the design of the bossing of damper, the intensity of damper is effectively improved, it is to avoid damper deforms.
(2) by laser welding after the two ends of damper are flattened, the sealing of damper is effectively improved.

Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but not as of the present utility model
Limit.
Fig. 1 is a kind of front view of above-mentioned damper of the present utility model；Fig. 2 is above-mentioned one kind of the present utility model
The cross-sectional view of damper；Fig. 3 is a kind of each several part composition of the cross-sectional view of above-mentioned damper of the present utility model
Figure；Fig. 4 is the scheme of installation of above-mentioned a kind of damper of the present utility model and the oily rail including the damper.Refer to
Shown in Fig. 4 to Fig. 3.Show：One oily rail 3, damper 1 is positioned in oily rail 3, and damper 1 is encapsulated in oily rail by a capping 4
In 3.Damper 1 is formed as bar by head to afterbody, and the damper 1 of the bar is approximately the bar of the shape that is in line
Shape.Run through along the centerline direction of damper 1 in the inside of damper 1 and offer through hole 2, and the two ends of damper 1 are welded.
The cross sectional shape of damper 1 includes the Part I 11, Part II 12, the Part III the 13, the 4th that are sequentially connected
15 5 parts in part 14 and Part V constitute, and Part I 11 is semicircle, and Part II 12 is isosceles trapezoid, second
The short side of 12 isosceles trapezoids is divided to be overlapped with the semicircular diameter side of Part I 11；Part IV 14 is isosceles trapezoid, the 5th
15 are divided to be semicircle, the short side of the isosceles trapezoid of Part IV 14 overlaps with the semicircular diameter side of Part V 15；Part III
