Abstract
The utility model discloses the 40 electric hammer head anti-loose structures of one kind of power tools technology field, including pivoted housing, steel bushing is connected at the left end switching of the pivoted housing, and pivoted housing left end connects electric hammer head, the pivoted housing right end connects electric hammer ontology, and elastic spring is socketed on pivoted housing, pivoted housing and steel bushing interference fit in the utility model, the anti-loosing effect for playing good electric hammer head, greatly increases the service life of electric hammer.
Description
Technical field
The utility model discloses a kind of 40 electric hammer head anti-loose structures, specially power tools technology field.
Background technique
40 or more big electric hammer impact forces are big, and vibration is big, and head construction is easy to fall off, and is all with screw thread knot on present society
Structure or gasket add axle elastic spring.These structure service lifes are not permanent, general 50 hours or so, cause this existing
As the reason of be punching when impact force it is big, vibration is big, and screw thread can loosen, and gasket adds axle elastic spring structure, acutely shake
Gasket ceaselessly impacts elastic spring when dynamic, and elastic spring is caused to slide, for this purpose, we have proposed a kind of 40 electric hammer heads are locking
Structure comes into operation, to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of 40 electric hammer head anti-loose structures, to solve to mention in above-mentioned background technique
Out the problem of.
To achieve the above object, the utility model provides the following technical solutions: a kind of 40 electric hammer head anti-loose structures, including
Pivoted housing is connected with steel bushing at the left end switching of the pivoted housing, and pivoted housing left end connects electric hammer head, and the pivoted housing right end connects electric hammer
Ontology, and elastic spring is socketed on pivoted housing.
Preferably, the pivoted housing be equipped with circlip groove compatible with elastic spring, and on pivoted housing with the junction of steel bushing
Equipped with slot compatible with steel bushing.
Preferably, the internal diameter of the steel bushing is slightly larger than the outer diameter of elastic spring, and steel bushing inner wall is equipped with ring recess, the steel bushing
Gapless between inner hole and elastic spring.
Preferably, in the steel bushing force fit pivoted housing.
Preferably, the steel bushing inner wall is pressed on the outside of elastic spring.
Compared with prior art, the utility model has the beneficial effects that after the utility model steel bushing force fit cannot on
Lower play, gapless between steel bushing inner hole and elastic spring, for hoop on elastic spring, elastic spring can not skid off retaining ring forever
Slot, elastic spring can not skid off, and subsequent constitutional detail can not just fall off, and service life was up to 300 hours or more.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model scheme of installation.
In figure: 1 pivoted housing, 2 steel bushings, 3 elastic springs, 4 electric hammer heads, 5 electric hammer ontologies.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of 40 electric hammer head anti-loose structures, including turns
1 is covered, steel bushing 2 is connected at the left end switching of the pivoted housing 1, and 1 left end of pivoted housing connects electric hammer head 4,1 right end of the pivoted housing connection
Electric hammer ontology 5, and elastic spring 3 is socketed on pivoted housing 1.
Wherein, the pivoted housing 1 is equipped with circlip groove compatible with elastic spring 3, and the connection on pivoted housing 1 with steel bushing 2
Place is equipped with slot compatible with steel bushing 2, and the internal diameter of the steel bushing 2 is slightly larger than the outer diameter of elastic spring 3, and 2 inner wall of steel bushing is set
There is a ring recess, gapless between 2 inner hole of steel bushing and elastic spring 3, in the 2 force fit pivoted housing 1 of steel bushing, the steel bushing 2
Inner wall is pressed on the outside of elastic spring 3.
Working principle: it is 30.5 that elastic spring 3, which is packed into the outer diameter on pivoted housing 1 after circlip groove, and the internal diameter of steel bushing 2 is
30.6, so elastic spring 3 is impossible swell in the circlip groove that diameter is 30.6, while pivoted housing 1 is matched with 2 interference of steel bushing
It closes, cannot slide up and down, then elastic spring 3 is impossible to glide, and causes steel bushing 2 that cannot fall off, to play anti-loosing effect.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
