Specific embodiment
With reference to embodiment and accompanying drawing, flashlight is further described in detail.
Refer to Fig. 1 to Fig. 3, the pocket lamp 100 of an embodiment, including cylinder 10, blind nut 20, lamp socket 30, multi-directional ball
40th, lamp holder 50, connect lid 60 and with tail-hood 70, light source assembly 80 and battery 90.Blind nut 20 is screwed onto on cylinder 10, multi-directional ball 40
Through blind nut 20 and be arranged on lamp socket 30, lamp holder 50 is movably connected on lamp socket 30 by screw thread, and tail-hood 70 is screwed onto
On cylinder 10.
Refer to Fig. 2 and 3, the substantially hollow cylinder of cylinder 10, cylinder 10 includes shell 110 and inner shell 120, inner shell
120 are contained in shell 110, and inner shell 120 is used for the conductor (not shown) housing battery 90 and connecting battery electrode, connects battery
The conductor of electrode is connected with the both positive and negative polarity of lamp socket 30 respectively.Understand, the two ends of shell 110 are provided with external screw thread 112 He in conjunction with Fig. 4
Screw thread 114, blind nut 20 is threaded on the screw thread 114 of cylinder 10, and cylinder 10 and blind nut 20 have cooperatively formed host cavity 116,
Host cavity 116 is used for housing multi-directional ball 40.Tail-hood 70 is threaded on the external screw thread 112 of the other end.Shell 110 can be gold
Belong to cylinder or plastic barrel.
The female thread of blind nut 20 is screwed together with the screw thread 114 of shell 110, i.e. one end of blind nut 20 and cylinder 10 screw thread
Connect.The other end of blind nut 20 has spherical end surface 210, offers through hole 220 on spherical end surface 210 end face, so as to make to
The screw rod 402 of ball 40 passes through.Multi-directional ball 40 is housed in the host cavity of cylinder 10 and the spherical end surface 210 inwall formation of blind nut 20
In 116.
Refer to Fig. 2 and Fig. 5, lamp socket 30 is matched with host cavity 116.Lamp socket 30 is provided with external screw thread 302, female thread
303rd, screw 304, inner chamber 305.Light source assembly 80 is locked in the screw 304 of lamp socket 30 by screw 307, thus by light sources
Part 80 is fixed in the inner chamber 305 of lamp socket 30, this fixed form more firm it is not easy to loosening.As light source assembly 80 changed by need,
Screw 307 is unloaded, then the light source assembly more renewing, easy to operate.
Refer to Fig. 2 and Fig. 6, multi-directional ball 40 includes spheroid 401 and the screw rod 402 being connected with spheroid 401.Spheroid 401 is lived
Move and be arranged in host cavity 116.The screw rod 402 of multi-directional ball 40 passes through the through hole 220 of blind nut 20, and screw rod 402 is away from spheroid 401
One end is locked on the female thread 303 of lamp socket 30.The rotation therefore passing through multi-directional ball 40 can adjust the direction of lamp socket 30 with multi-angle.
Multi-directional ball 40 is used for adjusting the diameter depending on the through hole 220 on the spherical end surface 210 of blind nut 20 for the angle of lamp holder corner,
For avoiding multi-directional ball 40 therefrom to deviate from and in order to ensure suitably large-scale corner, the diameter outline of described through hole 220 is less than ten thousand
To the diameter of the spheroid 401 of ball 40, and the diameter of through hole 220 be larger than screw rod 402 cross section maximum gauge.I.e. ten thousand
Spheroid 401 diameter to ball 40 > through hole 220 diameter > multi-directional ball 40 screw rod 402 cross section maximum gauge.
In order to reduce the frictional dissipation to spheroid 401 and provide certain cushioning effect to improve the spirit of multi-directional ball 30 steering
Activity, can arrange a bolster 403 in host cavity 116.Bolster 403 is offseted with the sphere of spheroid 401, in the present embodiment

Face coordinates.In other embodiments, cushion pad 403 can also be cushion collar etc..Bolster 403 and the sphere of described spheroid 401
The contact surface offseting constitutes the bottom surface of above-mentioned host cavity 116.
Refer to Fig. 2 and Fig. 7, lamp holder 50 is provided with female thread 501, around light source assembly 80 curved reflection face 502,
Screw thread 503 and endoporus 504.Lamp holder 50 is movably attached on the external screw thread 302 of lamp socket 30 by female thread 501, light source assembly 80
Through endoporus 504, when needing to adjust poly- astigmatism, can adjust the distance of lamp holder 50 and lamp socket 30 by Rotatable lamp holder 50, by lamp
The curved reflection face 502 on light source assembly 80 and lamp holder 50 on seat 30 is pulled open or is furthered, to adjust light source assembly 80 and arc
The distance between focus of shape reflective surface 502, thus flashlight 100 carries out poly- floodlight adjustment effect.Also set up on lamp holder 50
There are the light-guiding shade 505 relative with light source assembly 80 and trim ring 506, and light-guiding shade 505 is locked at by lamp holder 50 by trim ring 506
So that light-guiding shade 505 is fixed on lamp holder 50 on screw thread 503.In other embodiments, lamp holder 50 can also be with light-guiding shade 505
It is integrally formed, now trim ring 506 can omit.
Refer to Fig. 2 and Fig. 8, connect and be threaded 602 on lid 60.Connect lid 60 and lamp holder 50 is locked in by screw thread 602
On female thread 501.In the present embodiment, connect lid 60 and also include arc inner wall 604, blind nut 20 has spherical end face, blind nut 20
Spherical outer face with connect lid 60 arc inner wall 604 cooperation contact, for adjust angular dimension so that connect cover 60 to
Blind nut 20 mobile one end distance, thus lamp holder 50 can be towards the mobile one end in blind nut 20 direction distance.In other embodiments, connect
Lid 60 can also omit, and the external screw thread 302 being connected with lamp holder 50 in lamp socket 30 arranges limited block away from the end of lamp holder 50
Thus reaching the position-limiting action to lamp holder 50.
During assembling pocket lamp 100, first battery 90 is encased in the inner shell 120 of cylinder 10, then tail-hood 70 is sold cylinder
On the external screw thread 112 of the shell 110 of body 10, then light source assembly 80 is locked at the screw 304 of lamp socket 30 by screw 307
Interior, then by trim ring 506, light-guiding shade 505 is locked on the screw thread 503 of lamp holder 50, then again by the female thread 501 of lamp holder 50
Rotate on the external screw thread 302 of lamp socket 30, then the screw thread 602 connecting lid 60 is locked on the female thread 501 of lamp holder 50, Ran Houzai
Multi-directional ball 20 is passed through blind nut 20 to be locked on the female thread 303 of lamp socket 30, finally cushion pad 403 is placed in host cavity 116,
Again by the cooperation of the spheroid 401 of multi-directional ball 20 and cushion pad 403, by the shell 110 of the female thread 201 of blind nut 20 and cylinder 10
External screw thread 102 lock together, complete assemble.
Multi-directional ball 40 activity that above-mentioned pocket lamp 100 includes cylinder 10 is housed in host cavity 116, by multi-directional ball 40
Rotation can flexibly control lamp holder 50 to rotate, thus the direction of illumination of pocket lamp 100 can carry out multi-angle adjustment as needed.
Refer to Fig. 9, Fig. 9 is the schematic diagram that pocket lamp 100 adjusts certain angle.Simultaneously as lamp holder 50 passes through screw thread movably
It is connected on lamp socket 30, lamp holder 50 can move forward and backward with respect to lamp socket 30, will be anti-with the arc on lamp holder 50 for light source assembly 80
Bright finish 502 zooms out or furthers, and adjusts light source assembly 80 and curved reflection by adjusting lamp holder 50 with the relative position of lamp socket 30
The distance between the focus in face 502, thus flashlight 100 carries out poly- floodlight regulation, realizes direction of illumination and optically focused can be flexible
Adjust, the structure of pocket lamp 100 is simple, easy to assembly simultaneously, be conducive to processing and use.
Embodiment described above only have expressed the several embodiments of the present invention, and its description is more concrete and detailed, but simultaneously
Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, some deformation can also be made and improve, these broadly fall into the guarantor of the present invention
Shield scope.Therefore, the protection domain of patent of the present invention should be defined by claims.
