Abstract
The utility model discloses an electric tool sealing element. The electric tool sealing element comprises an annular body and is characterized by further comprising a reinforcing framework. The reinforcing framework is arranged in the annular body. A flexure part is formed on the inner side of the annular body. The flexure part extends backwards to form a dustproof lip which is slantly arranged. The flexure part extends towards the front side to form a sealing lip which is slantly arranged. A sealing position is formed between the dustproof lip and the sealing lip. The electric tool sealing element solves the problems that most existing electric tool sealing elements are pure rubber matrix sealing elements, the pure rubber matrix sealing elements are usually insufficient in strength when used for sealing components which move repeatedly and have pressure, as a result, the pure rubber matrix sealing elements are damaged, and the service life of the pure rubber matrix sealing elements is short. Meanwhile, an existing electric tool sealing element is provided with only one lip, therefore, dust particles still cannot be prevented from entering the sealing element, and the performance and the service life of the sealing element are greatly affected. In order to solve the problems, the electric tool sealing element is simple in structure, convenient to use, capable of playing a good role in dust prevention, quite high in strength, and quite long in service life.
Description
Technical field
The utility model relates to a kind of Sealing, particularly relates to a kind of electric tool Sealing.
Background technique
Sealing is exactly the parts that seal, rise the gas leakage leakage of oil that prevents from leaking parts.Present electric tool Sealing adopts pure colloid Sealing, and whole intensity is lower, when the parts of the repeatedly motion that is sealed with pressure often because insufficient strength, thereby cause the damage of Sealing, working life is shorter.Present Sealing only is provided with a lip simultaneously, can not prevent entering of dust granule like this, has greatly affected performance and the working life of Sealing.
The model utility content
The electric tool Sealing adopts pure colloid Sealing in order to solve in the prior art, when the parts of the repeatedly motion that is sealed with pressure often because insufficient strength, thereby cause the damage of Sealing, working life is shorter.Present Sealing only is provided with a lip simultaneously, can not prevent entering of dust granule like this, the performance of Sealing and the problem in working life have greatly been affected, it is a kind of simple in structure that the utility model provides, easy to use, can play better dust-proof effect, and have higher-strength, the electric tool Sealing that working life is long.
In order to address the above problem, technical solution adopted in the utility model is:
A kind of electric tool Sealing, comprise ring body, it is characterized in that: also comprise web frame, in ring body, be provided with web frame, the inboard deflection division that forms of described ring body, described deflection division extends back and forms the dust excluder lips that is obliquely installed, and described deflection division extends to form the sealing lip that is obliquely installed to the front side, form sealing station between described dust excluder lips and the sealing lip.
Aforesaid a kind of electric tool Sealing is characterized in that: chamfering before ring body outboard end face forward position forms.
Aforesaid a kind of electric tool Sealing is characterized in that: chamfering after ring body outside end face rear positions forms.
Aforesaid a kind of electric tool Sealing is characterized in that: described ring body adopts rubber material to make.
Aforesaid a kind of electric tool Sealing is characterized in that: described web frame adopts ferrous material to make.
Aforesaid a kind of electric tool Sealing is characterized in that: described sealing lip lowest point height is lower than dust excluder lips lowest point height.
The beneficial effects of the utility model are: the utility model electric tool Sealing is provided with web frame in ring body, greatly improved the bulk strength of Sealing, can be used for being sealed with the reciprocating parts of pressure, sealed product that can instead of pure glue spare, prolonged the working life of Sealing, provided cost savings.Described deflection division extends back and forms the dust excluder lips that is obliquely installed simultaneously, described deflection division extends to form the sealing lip that is obliquely installed to the front side, be provided with two lips on the Sealing, wherein dust excluder lips can be used for preventing that dust from entering the sealing position, improve sealability, prolonged the working life of parts.
Description of drawings
Fig. 1 is the utility model electric tool seal configuration schematic representation.
Fig. 2 is the structure for amplifying schematic representation of A part among Fig. 1.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Shown in Fig. 1-2, a kind of electric tool Sealing comprises ring body 1 and web frame 2, is provided with web frame 2 in ring body 1, and described ring body 1 adopts rubber material to make, and described web frame 2 adopts ferrous material to make.Chamfering 7 before ring body 1 outboard end face forward position forms, chamfering 6 after ring body 1 outside end face rear positions forms.The described ring body 1 inboard deflection division 3 that forms, described deflection division 3 extends back and forms the dust excluder lips 4 that is obliquely installed, and described deflection division 3 extends to form the sealing lip 5 that is obliquely installed to the front side, form sealing station 8 between described dust excluder lips 4 and the sealing lip 5.Described sealing lip 5 lowest point height are lower than dust excluder lips 4 lowest point height.
The utility model electric tool Sealing is provided with web frame 2 in ring body 1, greatly improved the bulk strength of Sealing, can be used for being sealed with the reciprocating parts of pressure, sealed product that can instead of pure glue spare, prolonged the working life of Sealing, provided cost savings.Described deflection division 3 extends back and forms the dust excluder lips 4 that is obliquely installed simultaneously, described deflection division 3 extends to form the sealing lip 5 that is obliquely installed to the front side, be provided with two lips on the Sealing, wherein dust excluder lips 4 can be used for preventing that dust from entering the sealing position, improve sealability, prolonged the working life of parts.
More than show and described basic principle of the present utility model, major character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification 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.
