Abstract
A kind of sub warhead electric hammer impact minor structure, including impacting sub- ontology and fixing ring, the head and tail portion of the sub- ontology of impact are all made of the bullet header structure that end face is spherical surface, it is additionally provided with profile seal ring recess between the head and the middle front part of the sub- ontology of impact of the sub- ontology of impact, the fixing ring is sleeved in the profile seal ring recess.The utility model provides a kind of can effectively prevent and impacts sub- fracture, feather plucking, oil leak, sub warhead electric hammer convenient for assembly impact minor structure.
Description
Technical field
The utility model is related to electric tool device technical fields, impact minor structure more particularly, to a kind of sub warhead electric hammer.
Background technology
The electric hammer of conventional power tool is that one kind is punched on concrete, is slotted, dabbing tool, in recent years, due to the people
The raising of standard of living, labour cost is higher and higher, and then the perforating efficiency of electric hammer and force de frappe is required to become better and better, in this way
Higher and higher, original impact such as Fig. 1 and Fig. 2 institutes of structure are required for the service life of impact of original structure on electric hammer
Show, using O-ring seal 10, be usually broken, the problems such as feather plucking oil leak, seriously affects service efficiency and the longevity of electric hammer
Life.
Invention content
In order to overcome existing electric hammer impact to there is the defect of fracture, feather plucking, oil leak, the utility model provides a kind of energy
It effectively prevent impacting sub- fracture, feather plucking, oil leak, sub warhead electric hammer convenient for assembly impact minor structure.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of sub warhead electric hammer impact minor structure, including the sub- ontology of impact and fixing ring, the sub- ontology of impact
Head and tail portion are all made of the bullet header structure that end face is spherical surface, the head of the sub- ontology of the impact with impact in sub- ontology before
Profile seal ring recess is additionally provided between portion, the fixing ring is sleeved in the profile seal ring recess.
Further, the angle of arbitrary two busbar extended lines in the round platform portion on the head of the sub- ontology of impact is 37 degree.
Further, middle front part of the head of the sub- ontology of impact close to the outer diameter and the sub- ontology of impact of annular groove side
Outer diameter it is identical.
The beneficial effects of the utility model are mainly manifested in：Spherical surface, the sealing ring on impact are used in impact subheader portion
Slot uses a sipes, designs in sipes and is effectively sealed using fixing ring, impacts sub- tail portion and equally uses at spherical surface
The generation for the problems such as reason can effectively prevent impact and be broken in this way in the case where strength increases, feather plucking, oil leak.
Description of the drawings
Fig. 1 is the explosive view of existing electric hammer impact.
Fig. 2 is the front view of Fig. 1.
Fig. 3 is the explosive view of the utility model.
Fig. 4 is the front view of Fig. 3.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings.
Referring to Fig.1~Fig. 4, a kind of sub warhead electric hammer impact minor structure, including the sub- ontology 1 of impact and fixing ring 2, institute
State the head for impacting sub- ontology 1 and tail portion be all made of the bullet header structure that end face is spherical surface, the head of the sub- ontology of the impact 1 with
It impacts between the middle front part of sub- ontology 1 and is additionally provided with profile seal ring recess, the fixing ring 2 is sleeved on the fixing ring
In slot.
Further, the angle of arbitrary two busbar extended lines in the round platform portion on the head for impacting sub- ontology 1 is 37 degree.
Further, the head of the sub- ontology of the impact 1 close to annular groove side outer diameter with impact in sub- ontology 1 before
The outer diameter in portion is identical.
The design principle of the utility model is：Former and later two end faces for impacting sub- ontology 1 are designed to spherical structure, will be original
Two O-ring slots change be designed to that is widened a profile seal ring recess；Head uses 37 degree of angle bullet header structures, improves
The bearing capacity on block stamp head ensures that impact will not be broken, feather plucking and oil leak situation.
The utility model is mainly used in electric tool electric hammer product.
