The utility model discloses a structure setting is comparatively reasonable, has improved the intensity of lip, also avoids the lip to damage because of frictional force when using to be favorable to improving life and dustproof stability, solved that can warp and to influence the technique of dustproof effect not enough when dustproof sealing uses for a long time in the conventional art.
Description
Technical field
The utility model is specifically related to a kind of dust seal.
Background technology
Dust seal is generally provided with during damper use to carry out dust-proof, and the dust seal of conventional art is mainly using complete
Glue dust seal, it is set in when in use on the decoupling rod of damper, so as to prevent dust from entering inside damper from decoupling rod,
It is poor yet with the rigidity of full glue dust seal while the lip dust seal of dust seal is not enough, when in use lip with subtract
The frictional force of shake device is larger, is easily deformed when using for a long time so as to affect dust-proof effect.
The content of the invention
The purpose of this utility model is to provide the dust seal that a kind of stability in use is good and dust-proof effect is strong, it is intended to solve to pass
Dust seal long-time can deform when using and affect the technical deficiency of dust-proof effect in system technology.
The technical scheme for realizing the utility model purpose is a kind of dust seal, including rubber dust-proof envelope body and main dust seal bone
Frame, it is internal that the main dust seal skeleton is embedded in rubber dust-proof envelope, have on the center bore inner wall that the rubber dust-proof seals body with
The dust excluder lips of damper link obvolvent, the dust excluder lips include least one set C font lip, and in rubber dust-proof envelope C is embedded with vivo
Font cushioning frame, the two ends of the C fonts cushioning frame are extended in C font lips, embedding in vivo in rubber dust-proof envelope
Bar is compressed, described one end for compressing bar is weldingly fixed on main dust seal skeleton, the other end is weldingly fixed on C fonts buffering bone
The arc-shaped side center of frame, is provided with dust arrest groove on the end face that the rubber dust-proof seals body, and the dust arrest groove is anti-in rubber
Be covered with dust on the end face of body and air contact and the centrally disposed hole of dust arrest groove outside.
Be provided with spheroid in the end of the C fonts cushioning frame, the end body one of institute's spheroid and C font cushioning frames into
Type.
The C fonts lip is two groups.
Synchronous muscle bar is welded between two C font cushioning frames.
The utility model has positive effect：Structure setting of the present utility model is relatively reasonable, and it is sealed in rubber dust-proof
Main dust seal skeleton is increased in vivo, such that it is able to prevent rubber dust-proof envelope deformation, while lip is arranged be C-shaped, and
C font cushioning frames are set up in C font lips, with preferable shock-absorbing capacity, the intensity of lip is not only increased, while
Lip can be avoided to damage because of frictional force when in use, so as to be conducive to improving service life and dust-proof stability, solve biography
Dust seal long-time can deform when using and affect the technical deficiency of dust-proof effect in system technology, strong applicability and practicality is good.
Description of the drawings
In order that content of the present utility model is more likely to be clearly understood, below according to specific embodiment and with reference to attached
Figure, is described in further detail to the utility model, wherein：
Fig. 1 is structural representation of the present utility model.
Specific embodiment
(embodiment 1)
Fig. 1 shows a kind of specific embodiment of the present utility model, and wherein Fig. 1 is structural representation of the present utility model
Figure.
Fig. 1, a kind of dust seal, including rubber dust-proof envelope body 1 and main dust seal skeleton 2 are seen, in the main dust seal skeleton 2
It is embedded in rubber dust-proof envelope body 1, has dust-proof with damper link obvolvent on the center bore inner wall that the rubber dust-proof seals body 1
Lip 3, the dust excluder lips 3 include least one set C font lip, and in rubber dust-proof envelope body 1 C fonts cushioning frame 4 is embedded with, described
The two ends of C fonts cushioning frame 4 are extended in C font lips, are embedded with rubber dust-proof envelope body 1 and are compressed bar 5, described to support
One end of depression bar 5 is weldingly fixed on main dust seal skeleton 2, the other end is weldingly fixed in the arc-shaped side of C fonts cushioning frame 4
The heart, on the end face that the rubber dust-proof seals body 1 dust arrest groove 6 is provided with, the dust arrest groove 6 in rubber dust-proof envelope body 1 with
The outside on the end face of the air contact and centrally disposed hole of dust arrest groove 6.It is dust-proof that it increased in vivo master in rubber dust-proof envelope
Envelope skeleton, such that it is able to prevent rubber dust-proof envelope deformation, while lip is arranged being C-shaped, and sets up in C font lips
C font cushioning frames, with preferable shock-absorbing capacity, not only increase the intensity of lip, while can also avoid lip from using
When damage because of frictional force.
The end body one of spheroid 7, institute's spheroid 7 and C fonts cushioning frame 4 is provided with the end of the C fonts cushioning frame 4
Shaping.Spheroid is provided with, causes lip to damage such that it is able to prevent lip from compressing with the end edge of C font cushioning frames, and
Contact for arc when can ensure that and being included with connecting rod, it is ensured that the stability of contact, so as to the dust-proof effect of dust seal can be ensured.
The C fonts lip is two groups.
Synchronous muscle bar 8 is welded between two C font cushioning frames.Such that it is able to make each lip embrace with connecting rod all the time
Close.
Structure setting of the present utility model is relatively reasonable, so as to be conducive to improving service life and dust-proof stability, solves
Can deform when dust seal long-time is used in conventional art and affect the technical deficiency of dust-proof effect, strong applicability and practicality
It is good.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
