Description
The utility model relates to a kind of double section rotary control flashlight.
The conventional batteries of tradition flashlight because of using general osram lamp and being correlated with, and for conveniently holding use, this type of flashlight volume homogeneous phase commonly used is worked as big, and is inconvenient to carry.And its length of miniaturization flashlight is about the 3-5 centimetre, and barrel diameter is then for about 1.5-2.0 centimetre, it can consistently with the carry-on articles of key gathering-device and so on easily be carried and is equipped with for use.
Modern age, semiconductor science and technology constantly progressed greatly, and need not use the light emitting diode (LED) of filament can be made as various different colours, and have the function of high brightness even superbright degree, gradually can replace conventional bulb, and be widely used in the product of various different field.The LED of this type of small size also makes to make as above-mentioned miniaturization flashlight certainly becomes possibility.
The conventional bulb of using filament is that Yu Yiduan is provided with the thread metallic sheath it is bolted in the lamp socket that contains internal screw thread, but existing LED then makes its two poles of the earth pin expose, and therefore it will be used in and promptly need use diverse lamp socket connecting structure on the flashlight.Show the existing LED bulb of this kind flashlight as Fig. 1, it comprises a main cylinder 10, this main cylinder 10 top interlockings one cover cap 11, the bottom then engages a bottom 12, and its inside then is provided with elements such as spring 13, insulation sleeve 14, battery pack 15, lamp socket 16, LED17 and reflector 18 in regular turn.Wherein, 171,172 on the two poles of the earth pin of LED17 can be inserted in lamp socket 16 relative openings 161,162, and this lamp socket 16 will be because of being embedded the upspringing or descend of action movie 163,164 of combination with its activity, and can control flickering of LED.The existing LED flashlight structure of this kind is because the battery pack 15 that must change the outfit from the bottom, and flickering with cover cap 11 control LED, thereby the essential three-section type structure of using main cylinder 10, cover cap 11 and bottom 12, overall structure is except that than the complexity, it thoroughly also is not easy to be shortened again, be cooperated with LED structure and be embedded action movie simultaneously, very trouble is with bothersome on making for its lamp socket 16, and it is also unstable to drive the control action.
At the shortcoming that prior art exists, the purpose of this utility model is promptly providing a kind of double section rotary control flashlight, thereby can make this type of LED flashlight be more suitable for miniaturization because of only adopting double-joint type, and its anti-structural strength of falling can be provided; The main cylinder blind end more can cooperate assembling another connector and can locking to be loaded on other relative article.
For achieving the above object, the utility model is achieved through the following technical solutions a kind of double section rotary control flashlight, it is characterized in that: it is provided with the hollow main cylinder of a suitable length, and this main cylinder is provided with underseal closed end and upper shed, is provided with the internal screw thread section in inside slightly in contiguous upper open end; The end cap that is made as hollow equally then is provided with the outer screwed pipe that matches with above-mentioned internal screw thread section is spirally connected both each other; This end cap in the internal preset translucent cover, contain the main elements such as lamp socket of LED and contained spring; In the hollow inside of above-mentioned main cylinder that has made up and end cap, except that above-mentioned light-emitting device, and insert an at least one battery pack and a switch controlling device, make this battery pack and switch controlling device cooperate above-mentioned lamp socket contained spring to become to urge mutually joint in inside; Above-mentioned switch controlling device comprises an insulation sleeve, and metal spring pole socket sleeve is in this insulation sleeve, and this spring pole socket is provided with enlarged end up and down, and wherein an enlarged end presses the spring that defaults in the insulation sleeve expansion endoporus, and end touches part for metal in addition.
A this LED wherein utmost point pin stretches into lamp tube inside and touches spring, the then curved lamp socket periphery wall that is connected to of another utmost point pin.
The default bead rank portion of this translucent cover is assembled in end cover associated inner, and expose from the default loophole of end cover its end.
The sheathed metal circular tube of this end cover inwall cooperates location one optically focused translucent cover.
The metal of this switch controlling device touches the default concave regions inside of part.
The metal of this switch controlling device touches part and is made as the sheet that conveniently presses.
The battery pack of being located at main cylinder and end cover hollow inside thereof is loaded between lamp socket contained spring and the switch controlling device.
Be located at main cylinder and hold cover hollow switch inside control device to be loaded between lamp socket contained spring and the battery pack.
This battery pack bottom assembling one turriform spring.
This main cylinder blind end is established hanging device.
This main cylinder blind end is established a spiro connecting piece.
By a kind of double section rotary control flashlight of the utility model, overcome the shortcoming of prior art, reached the purpose of above-mentioned creation, the utility model is simple in structure, operates more convenient.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
