Abstract
The invention relates to a double dust cover-type front shock absorber which comprises a shank and a rod cylinder, wherein a rod cavity is formed in the rod cylinder; one end of the shank is inserted into the rod cavity, so as to be in movable fit with the rod cylinder; a skeleton dust cover is arranged on the opening of the rod cavity, and is in sliding and sealed fit with the shank; a corrugated dust cover is arranged on the outer wall, corresponding to the opening of the rod cavity, of the rod cylinder. The front shock absorber has the advantage that the rod cavity can be protected with the double dust covers, so that dust is prevented from entering the rod cavity to damage an oil seal, that is, the service life of the oil seal can be prolonged.
Description
Technical field
The present invention relates to a kind of two dust-proof bell-type front shock absorber.
Background technique
In front shock absorber, mainly comprise handle bar and bar cylinder, handle bar does shock-decreasing type and moves in bar cylinder, in the past, often has dust to enter in bar chamber, causes oil sealing to be ground away, affect the working life of vibration damper, and therefore, the dust-proof problem how solving vibration damper is very urgent.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides a kind of two dust-proof bell-type front shock absorber.
The technical solution adopted for the present invention to solve the technical problems is: a kind of two dust-proof bell-type front shock absorber, comprises handle bar and bar cylinder, offer bar chamber in described bar cylinder, coordinates in the insertion rod chamber, one end of described handle bar with formation activity between bar cylinder;
The opening in described bar chamber is provided with skeleton dust-proof cover, and described skeleton dust-proof cover and handle bar form slipper seal and coordinate; The bar drum outer wall of described bar chamber opening is provided with radiation fins dust-proof cover.
Further, described skeleton dust-proof cover comprises annular fixing body, the first dust-proof ring body and the second dust-proof ring body, described first dust-proof ring body is connected with annular fixing body, described second dust-proof ring body is connected with the first dust-proof ring body, leaves elastic gap between described second dust-proof ring body and annular fixing body.
Further, be provided with metal ring in described annular fixing body, metal ring improves the installation strength of annular fixing body.
Further, described annular fixing body, the first dust-proof ring body and the second dust-proof ring body are structure as a whole.
Further, the outer ring of described annular fixing body forms installation step, and described installation step coordinates with the bar chamber of bar cylinder.Installation step improves the installation strength between skeleton dust-proof cover and bar cylinder.
Further, described radiation fins dust-proof cover offers exhaust port.
The invention has the beneficial effects as follows: the protection that can realize two dust cover to bar chamber, avoid dust to enter in bar chamber and destroy oil sealing, extend the working life of oil sealing.
Skeleton dust-proof cover relies on two dust-proof ring body, guarantees its dust-proof effect further.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is the schematic diagram of vibration damper of the present invention;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1;
Wherein, 1, bar cylinder, 2, handle bar, 3, skeleton dust-proof cover, 30, annular fixing body, the 31, first dust-proof ring body, the 32, second dust-proof ring body, 33, metal ring, 4, radiation fins dust-proof cover, 41, exhaust port.
Embodiment
The present invention is further illustrated by reference to the accompanying drawings now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present invention in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Fig. 1 Fig. 2, a kind of two dust-proof bell-type front shock absorber, comprises handle bar 2 and bar cylinder 1, offers bar chamber in bar cylinder 1, coordinates in the insertion rod chamber, one end of handle bar 2 with formation activity between bar cylinder 1.
The opening in bar chamber is provided with skeleton dust-proof cover 3, and skeleton dust-proof cover 3 forms slipper seal with handle bar 2 and coordinates; Bar cylinder 1 outer wall of described bar chamber opening is provided with radiation fins dust-proof cover 4.
Skeleton dust-proof cover 3 comprises annular fixing body 30, first dust-proof ring body 31 and the second dust-proof ring body 32, first dust-proof ring body 31 is connected with annular fixing body 30, second dust-proof ring body 32 is connected with the first dust-proof ring body 31, leaves elastic gap between the second dust-proof ring body 32 and annular fixing body 30.The annular dust-proof ring body 31 of fixing body 30, first and the second dust-proof ring body 32 are structure as a whole.Metal ring 33 is provided with in annular fixing body 30.Metal ring 33 improves the installation strength of annular fixing body 30.
The outer ring of annular fixing body 30 forms installation step, and installation step coordinates with the bar chamber of bar cylinder 1.Installation step improves the installation strength between skeleton dust-proof cover 3 and bar cylinder 1.
Radiation fins dust-proof cover 4 offers exhaust port 41.What radiation fins dust-proof cover 4 safety was guaranteed in the setting of exhaust port 41 does compression movement.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
