Abstract
The utility model relates to a metal framework dust ring, including metal framework and dust lip, wherein, metal framework includes that the skeleton erects the limit, horizontal limit of skeleton and skeleton hypotenuse, perpendicular limit of skeleton and the horizontal limit of skeleton are continuous perpendicularly, the skeleton hypotenuse links to each other with skeleton horizontal limit, the skeleton hypotenuse sets up in dust lip, dust lip includes vertical lip, first arch and second are protruding, first arch and second are protruding all to link to each other with the slope of vertical lip, dust lip axle cross -section forms " K " type structure, the skeleton erects the limit and the horizontal limit of skeleton all links to each other on one side of vertical lip, horizontal limit of skeleton and the bellied one end of second are point -blank, the utility model has the advantages of simple structure and reasonable design, have better withstand voltage wearability, can improve dustproof effect and sealing performance, increase life, reduce the cost.
Description
Technical field
The utility model designs a kind of dust ring, particularly a kind of metal frame dust ring.
Background technique
Dust ring, Main Function is that removing reciprocating piston bar is exposed at the dirts such as dust, sand-lime, rainwater and frost accompanying on cylinder outer surface, prevents external dust, rainwater enters sealing mechanism inside.In dust ring using process of the prior art, meeting compressive deformation, vibration etc., affect dust-proof effect and working life.
Model utility content
The purpose of this utility model is the defect for prior art, provides a kind of metal frame dust ring, has good withstand voltage wear resistance, improves dust-proof effect and sealability, increases working life.
The utility model is achieved by the following technical solutions.
A kind of metal frame dust ring, comprise metal frame and dust excluder lips, wherein, described metal frame comprises skeleton vertical edge, skeleton horizontal edge and skeleton hypotenuse, described skeleton vertical edge is vertically connected with skeleton horizontal edge, described skeleton hypotenuse is connected with skeleton horizontal edge, described skeleton hypotenuse is arranged in dust excluder lips, described dust excluder lips comprises vertical lip, first protruding and the second projection, described first projection all tilts to be connected with vertical lip with the second projection, dust excluder lips shaft section forms " K " type structure, described skeleton vertical edge and skeleton horizontal edge are all connected with vertical lip side, one end of described skeleton horizontal edge and the second projection point-blank.
Above-mentioned a kind of metal frame dust ring, wherein, between described skeleton hypotenuse and skeleton horizontal edge, angle is θ 1, and described θ 1 is between 95 ° ~ 120 °.
Above-mentioned a kind of metal frame dust ring, wherein, the described first protruding and vertically between lip angle is θ 2, and described θ 2 is between 70 ° ~ 85 °.
Above-mentioned a kind of metal frame dust ring, wherein, the angle between described first projection and the second projection is θ 3, and described θ 3 is between 110 ° ~ 150 °.
The beneficial effects of the utility model are:
Metal frame and dust excluder lips combine by the utility model, add the distortion resistance of dust ring, prevent dust ring compressive deformation in use, improve sealing; The dust excluder lips of " K " type structure makes it to have sharp-pointed lip type structure, reduces friction factor, effectively realizes stoping extraneous dust to enter system, also reduces the abrasion of equipment simultaneously; Point-blank, in using process, dust excluder lips is not easily stretched out in one end of skeleton horizontal edge and the second projection, is beneficial to and installs and sealing.
The angle of θ 1 of the present utility model is suitable for, and makes the close company property of metal frame and dust excluder lips better, ensure that the crushing resistance of dust ring; The angle of θ 2 and θ 3 is suitable for, and dust ring is formed and coordinates crush resistance, and make sealability better, dustiness is convenient to clean.
To sum up, the utility model structure is simple, reasonable in design, has good withstand voltage wear resistance, can improve dust-proof effect and sealability, increases working life, reduces cost.
Accompanying drawing explanation
Fig. 1 is axle cross-sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
A kind of metal frame dust ring, comprise metal frame 1 and dust excluder lips 8, wherein, described metal frame 1 comprises skeleton vertical edge 2, skeleton horizontal edge 4 and skeleton hypotenuse 3, described skeleton vertical edge 2 is vertically connected with skeleton horizontal edge 4, described skeleton hypotenuse 3 is connected with skeleton horizontal edge 4, between described skeleton hypotenuse 3 and skeleton horizontal edge 4, angle is θ 1, described θ 1 is between 95 ° ~ 120 °, described skeleton hypotenuse 3 is arranged in dust excluder lips 8, described dust excluder lips 8 comprises vertical lip 6, first protruding 5 and second projection 7, described first protruding 5 all tilts to be connected with vertical lip 6 with second protruding 7, angle between described first protruding 5 and vertical lip 6 is θ 2, described θ 2 is between 70 ° ~ 85 °, angle between described first protruding 5 and second projection 7 is θ 3, described θ 3 is between 110 ° ~ 150 °, dust excluder lips 8 shaft section forms " K " type structure, described skeleton vertical edge 2 and skeleton horizontal edge 4 are all connected with vertical lip 6 side, one end of described skeleton horizontal edge 4 and the second projection 7 point-blank.
The utility model structure is simple, reasonable in design, has good withstand voltage wear resistance, can improve dust-proof effect and sealability, increases working life, reduces cost.
Be only specific embodiment of the utility model disclosed in above-mentioned, this embodiment is only that clearer explanation the utility model is used, but not to restriction of the present utility model, the changes that any person skilled in the art can think of, all should drop in protection domain.
