Abstract
The utility model discloses a kind of bumper seal, the outer lip comprising seal ring body and arrange on seal ring body and epipharynx, outer lip and epipharynx are in the shape of the letter V angle, at the upper arc surface being provided with twice projection in seal ring body outer shroud circumferential position up and down successively of outer lip.This bumper seal is provided with the arc surface of twice projection on the outer lip of seal ring body, add sealing surface, good sealing effect, sealing surface is arc surface, not easy to wear, long service life, and make in mould, there is no obvious cusp, not easily produce dirt and easy to clean, production up-to-standard rate is high.The utility model is applicable to Sealing field.
Description
Technical field
The utility model relates to Sealing field, particularly relates to a kind of bumper seal.
Background technique
At present, hydraulic draft gear relies on hydraulic damping to carry out buffer deceleration to stopping to effect object thereon, plays protective action to a certain extent.Be applicable to the machinery such as lifting transport, elevator, metallurgy, harbour machinery, rail truck, be also applicable to drawer, door etc., its effect is the safety buffer device preventing hard collision from causing mechanism to damage in the course of the work.This buffer needs the excellent sealing of long service life, good sealing effect.Existing hydraulic draft gear dynamic sealing technology has two kinds, and the first is single circular arc lip rubber seal, and the second is Y type rubber seal.These two kinds of structures are all owing to adopting single lip, and Sealing sealing effect is bad, easy seepage, and y-type seal ring lip is sharp lip, easy to wear, easily reveal, and the working life of Sealing is shorter.Single circular arc lip seal installs trouble, and easily damage Sealing, Y type seal lip is sharp lip, and its production mould position of cusp easily produces dirt and not easy to clean, and production up-to-standard rate is lower.
Model utility content
For solving the problem, the utility model provides a kind of bumper seal of good sealing effect.
The utility model solves the technological scheme that its technical problem adopts:
A kind of bumper seal, comprises seal ring body and the outer lip that arranges on seal ring body and epipharynx, and outer lip and epipharynx are in the shape of the letter V angle, at the upper arc surface being provided with twice projection in seal ring body outer shroud circumferential position up and down successively of outer lip.
Be further used as the improvement of technical solutions of the utility model, epipharynx is positioned at the arc surface that seal ring body inner ring circumferential position is provided with twice projection up and down successively.
Be further used as the improvement of technical solutions of the utility model, the arc surface radian that epipharynx is provided with is less than the arc surface radian that outer lip is provided with.
Be further used as the improvement of technical solutions of the utility model, the height of outer lip is higher than epipharynx.
Be further used as the improvement of technical solutions of the utility model, seal ring body is positioned at the bottom surface of outer shroud circumferential surface perpendicular to seal ring body of hypomere.
Be further used as the improvement of technical solutions of the utility model, the inner ring circumferential surface of seal ring body is obliquely installed and is acute angle with bottom surface.
The beneficial effects of the utility model: this bumper seal is provided with the arc surface of twice projection on the outer lip of seal ring body, add sealing surface, good sealing effect, sealing surface is arc surface, not easy to wear, long service life, and make in mould, there is no obvious cusp, not easily produce dirt and easy to clean, production up-to-standard rate is high.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model embodiment overall structure schematic diagram.
Embodiment
Be clearly and completely described below with reference to embodiment and the accompanying drawing technique effect to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.Obviously; described embodiment is a part of embodiment of the present utility model, instead of whole embodiment, based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite not paying creative work, all belong to the scope of the utility model protection.
With reference to Fig. 1, the utility model is a kind of bumper seal, the outer lip 1 comprising seal ring body 3 and arrange on seal ring body 3 and epipharynx 2, outer lip 1 and epipharynx 2 are in the shape of the letter V angle, and outer lip 1 is positioned at the arc surface that seal ring body 3 outer shroud circumferential position is provided with twice projection up and down successively.
This bumper seal is provided with the arc surface of twice projection on the outer lip 1 of seal ring body 3, add sealing surface, good sealing effect, sealing surface is arc surface, not easy to wear, long service life, and make in mould, there is no obvious cusp, not easily produce dirt and easy to clean, production up-to-standard rate is high.
Outer lip 1 is provided with the arc surface of twice projection, adopts double-lip design, and sealing together that sealing surface is more than former Sealing, adds sealing surface, therefore good sealing effect.
As the utility model preferred embodiment, epipharynx 2 is positioned at the arc surface that seal ring body 3 inner ring circumferential position is provided with twice projection up and down successively.
The design of many lips, after making one bad seals, the sealing of another road can also continue to work, and extend the working life of product, and sealing surface is arc surface, not easy to wear, therefore long service life.
As the utility model preferred embodiment, the arc surface radian that epipharynx 2 is provided with is less than the arc surface radian that outer lip 1 is provided with.
Sealing entirety does not have larger projection, more convenient during installation, not fragile Sealing.
As the utility model preferred embodiment, the height of outer lip 1 is higher than epipharynx 2.
As the utility model preferred embodiment, seal ring body 3 is positioned at the bottom surface 4 of outer shroud circumferential surface perpendicular to seal ring body 3 of hypomere.
As the utility model preferred embodiment, the inner ring circumferential surface of seal ring body 3 is obliquely installed and is acute angle with bottom surface 4.
In the mould that Sealing described in the utility model uses, do not have obvious cusp, not easily produce dirt and easy to clean, production up-to-standard rate is high.
Certainly, the invention is not limited to above-mentioned mode of execution, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent distortion or replacement are all included in the application's claim limited range.
