Abstract
An improved flashlight switching structure. An insulation connecting ring is arranged at the connection of the tube head and the tube body of the flashlight, and is stuck at the outside of the connection of the tube head and the tube body; the utility model is connected with the tube body thread through the outer thread of the connecting ring; the metal tube outer casing is connected and switched on with the negative electrode of the bulb; the tube body metal tube is connected and switched on with the positive electrode of the bulb through a spring, batteries, a tube head positive contacting point; the tube head can be contacted with or separated from the tube body by rotating the tube body, to form a loop or to break the loop, therefore to realize the switching structure turning on or off the flashlight; the tube head and the tube body are connected through the outer thread of the insulation connecting ring under the abnormal working condition and are not switched on; when the flashlight is used, the tube body is rotated to enable the tube body front end contacting point to be contacted with the tube head negative electrode contacting point to form a loop and turn on the flashlight.
Description
Technical field
The utility model belongs to the switch of electricity field hand-held lighting device flashlight, be specifically related to a kind ofly set up an insulation connecting ring at flashlight tube head and stack shell connecting portion, by the rotation stack shell, tube head is linked to each other with stack shell or separate, thereby realize the flashlight switch device of switching function.
Background technology
In miniature flashlight art, how to dwindle the volume of flashlight switch, thereby reach flashlight is minimized, be an important problem.Present existing miniature flashlight, the general rotary switch technology of Cai Yonging, common way is directly to withstand battery with stack shell, the rotation stack shell makes anode contact or be separated with the lamp holder cathode contact, with the realization switching function.These class methods are owing to be not Elastic Contact, often loose contact, and the non-constant of reliability, and damage battery easily by pressure.
The utility model content
The utility model provides a kind of flashlight switch structure of improvement, solves the defective of poor reliability in original technology, makes the switch of miniature flashlight take the flashlight volume inside hardly; very reliable again; the battery that can also adequately protect avoids battery to be damaged by pressure, perhaps rocks in torch.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
Be adhesively fixed in the tube head of flashlight and the stack shell joining part outside connecting ring of an insulation is connected to form torch by the external screw thread and the stack shell of connecting ring.A tube shell is made of metal, and integral body links to each other with lamp pearl negative pole as negative pole; In the bottom of a tube built-in lamp socket of shell, establish the contact of a projection, be connected with the lamp pearl is anodal; Battery can be by the elastic force effect of spring, makes anode connecting cylinder head positive pole all the time when standby, is connected among the loop; GND connects the stack shell metal tube through spring.When the rotation stack shell, it is the tightest that stack shell is screwed to, and the stack shell front end touches a tube shell, and then lamp pearl, tube head, stack shell metal tube, spring, battery, the bottom cathode contact conducting of tube head form the loop, and torch is in open mode.When the rotation stack shell, stack shell only is connected with the external screw thread of insulation connecting ring, during not with tube shell conducting, then torch is in closed condition because of forming the loop.
The beneficial effects of the utility model are:
Because the utility model adopts the tube head to join with stack shell or the method for separating is come the switch torch, makes to increase hardly under the situation of torch minimum diameter and length and finishes switching function, is very beneficial for the product miniaturization; And such construction of switch is simple and reliable, does not have the possibility that lost efficacy; Also have, because battery is connected in the loop by the rubber-like spring, loose contact just can not appear in non-rigid the contact with the Elastic Contact of tube head bottom cathode contact to form battery; Also make battery be reduced to zero by the risk of being damaged by pressure, and any rocking can not arranged in stack shell because of screwing the stack shell overexertion.

The specific embodiment
Below in conjunction with accompanying drawing preferred implementation of the present utility model is done detailed description.
The be adhesively fixed connecting ring 106 of an insulation of flashlight tube 1 and stack shell 2 joining part outsides is connected to form torch by the external screw thread 107 and the stack shell 2 of connecting ring; A tube shell 101 is made of metal, and integral body links to each other with lamp pearl 102 negative poles as negative pole; In the bottom of a tube shell 101 built-in lamp sockets, the contact of establishing a projection is tube head positive pole 105, with 102 anodal connections of lamp pearl; Battery 205 can be by the elastic force effect of spring 204, makes anode connecting cylinder head positive pole 105 all the time when standby, is connected among the loop; Battery 205 negative poles connect stack shell metal tube 203 through spring 204.
When rotation stack shell 2, it is the tightest that stack shell 2 is screwed to, and terminal contacts 201 touches a tube shell 101 before the stack shell, then lamp pearl 102, a tube shell 103, stack shell metal tube 203, spring 204, battery 205, bottom cathode contact 105 conductings of tube head, form the loop, torch is in open mode.
When rotation stack shell 2, stack shell metal tube 203 is only contacted with the external screw thread 107 of insulation connecting ring, during not with 101 conductings of a tube shell, then torch is in closed condition because of forming the loop.
In sum, the utility model is a kind of modified form flashlight switch, and it increases torch diameter and length hardly, is beneficial to very much the product miniaturization; This construction of switch is simple and reliable in addition, does not have the possibility that lost efficacy; Add because battery passes through rubber-like spring string in the loop, form Elastic Contact and non-rigid contact, just the risk that loose contact and battery are not damaged by pressure can not occur, also can in stack shell, not rock; Whole switch is small and exquisite, reliable, easy to operate.
The above is a preferred embodiment of the present utility model only, and being not limited to the utility model only has this a kind of embodiment, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
