Abstract

The utility model relates to a water-proof plastic electric torch which comprises an electric torch body made of plastics, a spring installed in the bottom of the electric torch body, a glass sheet, a reflecting disk and a bulb socket, a contact sheet which is communicated with the metal sleeve of the bulb socket, a swing rod which is matched with the contact sheet and is connected with the spring in the bottom by a conductor, and a button which is arranged on the outer wall of the electric torch body and is corresponding to the swing rod, wherein, the glass sheet, the reflecting disk and the bulb socket are arranged in the head part of the electric torch body. The button drives a magnetic iron, and the attracting force of the magnetic iron leads the swing rod to be conducted with the contact sheet or be disconnected with the contact sheet. A sealing gasket is arranged among the end cover of the head part, glass and the electric torch body. The inside of the electric torch of the utility model is completely sealed, which ensures water protection. The utility model is especially suitable for fishermen, sailing ships, combat against a flood, and underwater operation.

Description

Water-proof plastic torch

The utility model relates to flashlight, guarantees effective waterproof, is particularly suitable for using in fisherman, boat, flood fighting and the underwater operation.

Flashlight is a kind ofly to have long historical articles for daily use, though its scope of application reduce gradually because the unique function that it is particularly suitable for moving, so still often standby by people.Existing flashlight can be divided into metal-back and plastic housing, but one of disadvantage that all exists is water funk drenching, promptly non-watertight, this is for (as the fisherman) on the ship and underwater operation personnel and when combating typhoon flood control (needing flashlight again especially), and is often wet by water and influence result of use and life-span.

The purpose of this utility model is to design a kind of waterproof plastic flashlight of drenching with rain, soaking of not being afraid of.

The solution of the utility model waterproof plastic flashlight technology is: a cylindrical shell is arranged, the head and the push button switch that link to each other with cylindrical shell are formed, mounting spring or reed in the bottom of cylindrical shell, so-called head has sheet glass, optical reflective disk and electric bead block, in the front end of cylindrical shell, contact is installed, contact UNICOM small electric bulb socket, the fork that matches with contact, fork connects conductor and connects the interior spring in cylindrical shell bottom, corresponding fork is installed push button outside cylindrical shell, magnet is arranged in the push button, between the end cap of head and sheet glass and cylindrical shell, seal washer is arranged.

The utility model is the waterproof plastic flashlight, compared with the prior art, between end cap and sheet glass and cylindrical shell, pacified the positiver sealing circle, most critical to be push button switch slide with the outer magnet of barrel wall, make fork and contact conducting or disconnection in the barrel wall, have not a particle of leak, guarantee sealing in the tube, thoroughly solved waterproof problem, realized that flashlight is under the situation of drenching with rain and take under water and use.

Fig. 1 is the utility model waterproof plastic flashlight structure schematic diagram;

Fig. 2 is the utility model waterproof plastic flashlight push button switch schematic diagram.

Below in conjunction with Fig. 1-Fig. 2 embodiment of the present utility model is elaborated.

The utility model is a kind of flashlight, and

battery

7,8 is installed in the cylindrical shell 6 that is made of plastics, cylindrical shell, and spring 9 is arranged in the bottom, and spring is fixed by pressing plate 10, also can be without the spring reed.Head at cylindrical shell connects end cap 1, and sealing ring 2 is installed between end cap and sheet glass 3 and optical reflective disk 4 and the cylindrical shell, and water can not be infiltrated in the tube, and electric bead block 5 is arranged under the optical reflective disk, and the small electric bulb socket 21 that small electric bulb 22 is installed is arranged in the electric bead block.Side at cylindrical shell is installed push button switch, and the part of its push button switch is in the wall of cylindrical shell, and a part is outside the wall of cylindrical shell.Switch bearing 11 is arranged in barrel wall, Metal Contact sheet 19 is arranged on the bearing, contact form galvanization, and the other end of contact cooperates with fork by screw 20 UNICOM's small electric bulb sockets 21, fork is fixing by pin 15, the motion of fork relies on the push button 13 and the magnet 14 of cylinder body outer wall to determine, when push button 13 backward the time, and the rear end 12 of attraction fork, fork front end 17 and contact 19 are disconnected, and torch does not work; And after the push button reach, the front end 17 of attraction fork makes fork front end 17 contact with contact 19, circuit turn-on, and torch is shinny, slides in chute 18 with pin 16 when push button is movable.In sum, the switch of waterproof plastic flashlight is to move with the outer magnet of barrel, makes the fork swing, and whether fork contacts with contact, and circuit turn-on or disconnection make sealing fully in the tube, have solved waterproof problem.

Claims

1, waterproof plastic water power tube, a cylindrical shell is arranged, the head and the push button switch that link to each other with cylindrical shell are formed, mounting spring or shell fragment in the bottom of cylindrical shell, so-called head has sheet glass, optical reflective disk and electric bead block, the interior contact 19 of installing of front end that it is characterized in that cylindrical shell 6, contact UNICOM small electric bulb socket 21, the fork that matches with contact, fork connects conductor and connects the interior spring 9 in cylindrical shell bottom, corresponding fork is installed push button 13 outside cylindrical shell, and magnet 14 is arranged in the push button, between the end cap 1 of head and sheet glass 3 and cylindrical shell 6 seal washer 2 is arranged.
