Abstract
The utility model discloses a leak-proof braking cup. The cup comprises a cup main body, wherein a ring-shaped braking primary lip extending outwards and a ring-shaped braking secondary lip extending outwards are arranged on the peripheral surface of the cup main body. The braking primary lip and the braking secondary lip are combined in a sealing way so that the leak-proof braking cup achieves stronger elasticity and ductility; the braking secondary lip plays roles of assisting the primary lip to seal and protecting the primary lip, which not only can improve the sealability of the leak-proof braking cup, but also can prolong the service life of the leak-proof braking cup; when braking, a brake has the advantages of stable working, good leak tightness, no leakage and long pressure maintaining time; and the leak-proof braking cup can better improves the quality of products, prolongs the service life of the products, and lowers the cost of maintenance.
Description
Technical field
The utility model relates to a kind of drg accessory, relates in particular to a kind of braking leather cup.
Background technology
Along with the development of auto trade, driven the development of vehicular spare parts industry, the braking leather cup that uses on the car brake belongs to consumable store, is easy to wearing and tearing, after the wearing and tearing, the leak tightness variation of leather cup, influence braking.At present, the braking leather cup of hydraulic brake is generally single procheilon structure, and as shown in Figure 2, this kind braking cup leather packing is relatively poor, fragile, causes braking unstable, influences traffic safety; And the frequent braking leather cup of changing, make car opertion and maintenance cost increase.
The utility model content
Technical problem to be solved in the utility model provides a kind of good seal performance, wear-resistant leakproof braking leather cup.
For solving the problems of the technologies described above, the technical solution of the utility model is: leakproof braking leather cup, comprise the leather cup main body, described leather cup main body outer peripheral face is provided with outward extending annular stop master's lip, and described leather cup main body outer peripheral face also is provided with the secondary lip of outward extending annular stop.
As a kind of optimized technical scheme, the secondary lip of described braking has one at least.
As a kind of optimized technical scheme, the outer circumference diameter of the secondary lip of described braking is littler than the outer circumference diameter of the main lip of described braking.
As a kind of optimized technical scheme, described leakproof braking leather cup is high polymerization oil proof rubber braking leather cup.
Owing to adopted technique scheme, leakproof braking leather cup comprises the leather cup main body, and described leather cup main body outer peripheral face is provided with outward extending annular stop master's lip, and described leather cup main body outer peripheral face also is provided with the secondary lip of outward extending annular stop; The sealing means that adopts main lip of braking and the secondary lip of braking to combine, has stronger elasticity and toughness, brake the effect that secondary lip plays auxiliary seal with respect to the main lip of braking and protects the main lip of braking, the sealing property of leakproof braking leather cup not only can be improved, the service life of leakproof braking leather cup can also be prolonged; And glancing impact drg working stability, good airproof performance, ne-leakage, dwell time are long, and the technical program can be improved the quality of products, prolong product life better, be reduced the maintenance expense.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the prior art constructions scheme drawing;
Among the figure: 1-leather cup main body; 2-brakes main lip; 3-brakes secondary lip.
The specific embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only some one exemplary embodiment of the present utility model has been described by the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, under the situation that does not depart from spirit and scope of the present utility model, can revise described embodiment with various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection domain of claim.
As shown in Figure 1, leakproof braking leather cup, comprise leather cup main body 1, described leather cup main body 1 outer peripheral face is provided with outward extending annular stop master's lip 2, described leather cup main body 1 outer peripheral face also is provided with the secondary lip 3 of outward extending annular stop, the secondary lip 3 of described braking has at least one (can certainly have a plurality of, can customize according to the practical application needs), in the present embodiment, leakproof braking leather cup is provided with a secondary lip 3 of braking, the outer circumference diameter of the secondary lip 3 of described braking is littler than the outer circumference diameter of the main lip 2 of described braking, brake the effect that secondary lip 3 plays auxiliary seal with respect to the main lip 2 of braking and protects the main lip 2 of braking, the sealing property of leakproof braking leather cup not only can be improved, the service life of leakproof braking leather cup can also be prolonged; Described leakproof braking leather cup is high polymerization oil proof rubber braking leather cup.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
