Description

Flashlight with tail rotary switch

The utility model relates to a kind of flashlight, refers to especially place switch connection, deenergization flashlight with afterbody.

At present, the microscler flashlight of traditional tubulose, motion with cervix helical makes its guide card or bulb, be switched on or switched off with battery, but this cervix helical structure often takes place that guide card can't contact with lamp housing or the bulb end can't contact with anode, causes phenomenons such as loose contact or the crooked short circuit of copper sheet, easily advance rainwater in addition with cervix helical, form short circuit, in addition, the key chain hole that afterbody is hung, the outstanding personnel that sharply also easily cause injure, easily rock during operation, exert all one's strength slightly and excessively also can eject battery or head, in a word, it is unreliable to use, even unsafe, again can not waterproof, operation is also inconvenient.

In view of this, the purpose of this utility model is that a kind of afterbody rotary switch flashlight will be provided, and it is reliable to reach contact, again can waterproof and easy to operate.

The purpose of this utility model is achieved in that it has body, tube face, bulb, reflective mirror, waterproof O type ring and battery, at the rear of battery one buffer spring is set, buffer spring rear in body is provided with the switches set of mainly being made up of switch, tailstock and screw, wherein switch is in the rear of tailstock, screw is in the place ahead of tailstock, rear side at switch has key chain hole, both sides have two semicircle valleys, its the place ahead has the protuberance of central zone open-work, and also fluted on protuberance; The place ahead of tailstock has external screw thread, and central authorities have hexagon ring; The screw top has catch, the centre has external screw thread and end has several boss, also has the hexagonal (hexagon)nut that matches with external screw thread in the middle of the screw in addition.

Owing to adopt such scheme: easy to operate, contact is steady, safe and reliable and have waterproof effect.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 3 is the switches set three-dimensional exploded view of the utility model embodiment.

Fig. 4 is the combination section of the utility model embodiment.

Among the figure: 1. body, 10. internal thread, 11. external screw threads, 12.O type ring, 13. heads, 130. internal screw thread, 131. reflective mirrors, 132. bulbs, 133. tube faces, 134. eyeglasses, 135.O the type ring, 14. batteries, 15. buffer springs, 16. screws, 160. catch, 161. external screw thread, 162. boss, 17. hexagonal (hexagon)nuts, 18. pads, 19.O type ring, 20. tailstock, 201. external screw threads, 202. hexagon rings, 21. switches, 210. pairs of semicircle valleys, 211. key chain hole, 212. grooves, 213.O type ring, 214. protuberances.

Consult shown in Fig. 1,2, outer, the inboard at the place ahead of the hollow body 1 of present embodiment and rear have external screw thread 11 and internal thread 10 respectively, and are provided with the O type ring 12 of a waterproof in the end of external screw thread 11, and external screw thread 11 is connected with the internal thread 130 of head 13.As for a tube face 133 and bulb 132 are housed in the body 1, the reflective mirror 131 for the reflection high light is equipped with in the outside of bulb 132 simultaneously, and eyeglass 134 and fireproof O type ring 135 be housed in addition in the outside of this reflective mirror 131, battery 14 can be put in inside as for body 1, and battery 14 rears (negative pole) are provided with a buffer spring 15 in the body 1.

Buffer spring 15 rears in body 1 are provided with the switches set of mainly being made up of switch 21, tailstock 20 and screw 16.Wherein switch 21 is in the rear of tailstock 20, and screw 16 is in the place ahead of tailstock 20; The afterbody of switch 21 has keyhole 211; and have two semicircle valleys 210 in its both sides; can protect staff or clothing not to hurt; protuberance 214 is extended in switch 21 the place aheads; and has a groove 212 that embeds O type ring 213 at its outer surface; and be an open-work 215 in the protuberance 214, be difficult for throwing off after making itself and tailstock described later 20 setting-ins, have and connect firm and waterproof effect.And the place ahead of tailstock 20 has external screw thread 201, and waterproof O type ring 19 is set in external screw thread 201 ends, and tailstock 20 front ends have a hexagon ring 202 inside and are provided with a pad 18, prevent that switch 21 from separating with tailstock 20, switch 21 is to be in the afterbody 20 inner transparent holes, and the interior open-work that hexagon ring 202 diameters wear than switch 21 the place ahead protuberances 214 rear of tailstock 20 (promptly) is bigger, so borrow pad 18 to terminate in its two (being hexagon ring 20 inside), supply T type screw 16 described later again, hexagonal (hexagon)nut 17 grades are stopped, hexagonal (hexagon)nut 17 is provided with in the hexagon ring 202 of tailstock 20, and forward-reverse within it, and the place ahead of screw 16 has a catch 160 and provides hexagonal (hexagon)nut 17 backstops to use, its rear has external screw thread 161 in regular turn and is screwed on the hexagonal (hexagon)nut 17 in the centre, so that hexagonal (hexagon)nut 17 can be made forward-reverse in the hexagon ring 202 of tailstock 20, and the rear of external screw thread 161 (promptly terminal) has several boss 162, embedding is located in the open-work 215 of switch 21 the place ahead protuberances 214, therefore, when screw 16 after being embedded by switch 21, promptly be difficult for throwing off, the head 13 of body 1 can't insert, make flashlight have no way of directly putting, the switches set that is combined into one simultaneously can borrow the external screw thread 201 in tailstock 20 the place aheads to screw into an obturator with waterproof O type ring 19 with the rear internal thread 10 of body 1, buffer spring 15 reaches the effect of action of giving 17 of battery 14 and hexagonal (hexagon)nuts.

Consult Fig. 3, shown in 4, because switch 21 is to borrow rotation mode to reach out, close, and then make bulb 132 bright or extinguish, when desiring to light bulb 132, only switch 21 is turned clockwise, at this moment, hexagonal (hexagon)nut 17 as make and break contact promptly can rotate with it by coping screw 16 synchronously, and tailstock 20 is fixed on the body 1, and make the external screw thread 161 at its catch 160 rears drive hexagonal (hexagon)nut 17 to reach, hexagonal (hexagon)

nut

17 and 14 on battery are provided with buffer spring 15 simultaneously, hexagonal (hexagon)nut 17 is slowly advanced to battery 14, and present the great conducting of contact-making surface, when switch 21 reverse rotations, hexagonal (hexagon)nut 17 promptly can be return in the opposite direction, and itself also be subjected to the restoring force of spring 15 this moment, thus very steadily (do not produce and shake phenomenon) and and make this flashlight circuit disconnection.

If will change battery 14 time, this moment only with tailstock 20 towards rotation counterclockwise, it can withdraw from separation by body 1 part, can reach, so on manipulating safety again quite easily and fast.
