The groove 1 of shape.The middle part of the shank of screw is tapping screw thread portion 4, and the rear portion of the shank of screw is the non-circular post in cross section
Shape structure 5, the head of screw are located at the front end of the shank of screw, set on the shank of screw in front of the tapping screw thread portion
There are two radial ringed raised 7,8, the annular recess 6 formed between them with shank of screw is O-ring seals auxiliary section, and annular is recessed
The surface in portion is the surface to be engaged with O-ring seals 3, and correspondingly, the width and height dimension of the annular recess all should
With the units specification of corresponding O-ring seals.Annular radial projection 8 and the self tapping spiral shell near the tapping screw thread portion
Line portion close to.
The groove adjusts bulb with convenient use instrument to be preferably interior hex-shaped recess or interior hexagonal plum blossom connected in star
Light screw a is installed on lamp body.
The rear portion of the shank of screw can be in that outer-hexagonal shape or outer-hexagonal are quincunx, can be with convenient use instrument outside lamp body
Portion rotates bulb light regulating bolt a, so as to realize the regulation to inclination.
The top surface of the head of screw is the sphere being engaged with the ball-and-socket of ball nut, and the head of screw can relative to ball-and-socket
To there is the rotational freedom in three directions.
The head of screw can be with hemispherical, and its bottom surface 9 can be plane, can also be more preferably perpendicular to screw
The plane of rod axis, it is engaged with the structure for facilitating with preventing head of screw from deviating from, obtains preferable screw anticreep effect.
The bulb light regulating bolt with self sealss is preferably made of metal material.
Two radial ringed raised inner sides (two sidewall surfaces of i.e. described annular recess) are vertical
In the plane of the axis of the shank of screw, for fixing O-ring seals 3 it can not be deviate from, two radial ringed projections
Outer side be preferably among evagination surface, such as can be circular conical surface, i.e., described radial ringed projection is closer to spiral shell
Nail rod is thicker, thinner closer to edge, Mold Making and part self-assembling formation when this structure one is conveniently easy to extrusion forming,
On the other hand it is easy to O-ring seals to be inserted in the annular recess from the rear end of the bulb light regulating bolt.
As shown in figure 4, the invention also discloses a kind of bulb light regulating bolt and the fit structure of lamp body, including lamp body
The 10 and bulb light regulating bolt a with self sealss.The lamp body is provided with the hollow columnar structures through lamp body wall, the post
The center through hole of shape structure is coaxial shoulder hole, is inside and outside divided into inner sector hole 13 and outer sector hole 11, inner sector hole 13 according to lamp body
Aperture be more than outer sector hole, be the step surface 12 of annular between two sector holes.The tapping screw thread portion of the bulb light regulating bolt with
The outer sector hole screw thread coordinates, the O-ring seals 3 being embedded between two radial ringed projections under elastic deformation,
The O-ring seals form radial seal with the inner sector hole 13.
The inner end aperture of the inner sector hole is arranged to extend out shape aperture 14, when installing bulb light regulating bolt thereto, rises
To guiding function.
The outer sector hole is unthreaded hole before the bulb light regulating bolt is screwed in, and its external screw thread is into the outer sector hole
Formed during screwing in the bulb light regulating bolt first.
The installation process of the fit structure of the bulb light regulating bolt and lamp body is：By O-ring seals 3 from the shank of screw
Rear end be inserted in shank of screw, then O-ring seals are turned into the annular recess 6 through described radial ringed raised 8.Led to using instrument
The bulb light regulating bolt a groove 1 is crossed, the inner end of shank of screw hollow columnar structures from lamp body is inserted, and
Tapping screw thread portion 4 is screwed on lamp body 10 in the outer sector hole unthreaded hole 11 of the hollow columnar structures, outer sector hole is formed external screw thread
While, the bulb light regulating bolt a is supported in the outer sector hole.Pass through pre-designed relative dimensions, O-ring seals
3 pass through rational compressed fit, formation lamp body 10 and the sealing at the bulb light regulating bolt cooperation with inner sector hole 13.Finally will
Bulb light regulating bolt a head of screw 2 coordinates with the ball-and-socket of ball nut 16, bulb light regulating bolt is fixed on ball nut 16
On, the outward flange of the ball-and-socket of ball nut 16 can be arranged to inside contract degree of lip-rounding formula, so that the edge of the bottom surface 9 of head of screw is complete
It is blocked within the ball-and-socket of ball nut, increase abjection power, so as to prevent screw bulb 2 from being taken off from the ball-and-socket of ball nut 16
Go out, and ball nut 16 is fixed on the speculum 15 for needing to fascinate.
The ball nut and the speculum are respectively positioned on the inboard of the lamp body i.e. in lamp house, and the speculum can fascinate
Ground is arranged on the lamp body.Ball nut is fixed on the speculum.The ball nut is provided with the ball-and-socket of Internal Spherical Surface shape,
And the area of its Internal Spherical Surface passes through elasticity between a whole Internal Spherical Surface, between the head of screw and ball-and-socket in half of Internal Spherical Surface and become
Shape mutually fixes.The lamp body, bulb light regulating bolt, O-ring seals, ball nut and speculum constitute front shining lamp adjustment list
The major part of member.
The course of work of the fit structure of the bulb light regulating bolt and lamp body is：Dimmed by using instrument rotating ballhead
At the column structure 5 at screw a rear portions, so that bulb light regulating bolt a rotates around own axes, because lamp body 10 is fixed
Motionless, lamp body 10 and bulb light regulating bolt a is coordinated by screw thread, thus bulb light regulating bolt a with respect to lamp body 10 to lamp body
When inboard is rotating translation, because the ball-and-socket of head of screw 2 and ball nut only has the free degree rotated, so ball nut is pushed away
Translation in the same direction is also followed in the dynamic also inboard translation to lamp body, correspondingly, one jiao of the speculum fixed with ball nut, therefore instead
Penetrate mirror fascinating there occurs some direction, when bulb light regulating bolt a with respect to lamp body 10 to when being rotating translation on the outside of lamp body, ball
The direction of action of head nut and speculum also respective opposed, thus achieves the regulation to inclination.
The bulb light regulating bolt with respect to lamp body inwards outwards occur axial displacement when, due to O-ring seals 3 all the time with ball
Head light regulating bolt a is relatively fixed, and O-ring seals 3 also inside and outside move in bulb light regulating bolt a under in inner sector hole 13,
The step surface 12 and described radial ringed raised 8 of annular are engaged, it is ensured that and O-ring seals 3 are remained in inner sector hole 13, because
This remains the reliable sealing between bulb light regulating bolt and lamp body.
