A battery is arranged in the body in which a magnet spring coil circuit board is provided with a magnetic spring tube, and on the outer wall corresponding to such magnetic spring tube of the barrel is arranged with a button device, the button of such device is provided with magnetic body. The waterproof member at the switch of the flashlight has good waterproof performance after long time service.

Description

Waterproof flashlight

Technical field

The utility model relates to a kind of flashlight, especially has the flashlight of water-proof function.

Background technology

The patent No. of application on October 14th, 2000 is that the waterproof flashlight of CN00249652.6 comprises head and stack shell, be provided with transparent bluff piece in the head, reflective mirror, small electric bulb and bearing thereof, be provided with battery in the stack shell, the afterbody opening of stack shell, one switch assembly is connected one with it, this switch assembly comprises housing and is arranged on the interior push-button switch of housing, described housing afterbody has the hole, the button of described press button is overhanging in this hole, the one waterproof press-button cover of being made by soft rubber-plastics material is lived described housing afterbody hole from caulked outside to inside, and its central blind hole then just in time holds outside the described press button and stretches button simultaneously.The press button place of this waterproof flashlight realizes waterproof by the waterproof press-button cover that the soft rubber material is made, but the waterproof jacket that this soft rubber is made is aging easily, fracture after long-term the use, can't continue to reach the waterproof purpose, so service life is shorter.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of waterproof flashlight, and the proof mechanism of water at the switch place of this waterproof flashlight can keep good water resistance in the long-term back of using.

For this reason, the waterproof flashlight that the utility model provides comprises head and stack shell, be provided with transparent bluff piece, reflective mirror, small electric bulb and bearing thereof in the head, be provided with battery in the stack shell, also be provided with magnetic red route of pipe line plate in the stack shell, have the magnetic red pipe on the magnetic red route of pipe line plate, corresponding magnetic red pipe is provided with push button mechanism on the stack shell outer wall, has magnet on the push button in the push button mechanism.

Owing to be provided with magnetic red route of pipe line plate in the stack shell of the waterproof flashlight that the utility model provides, have the magnetic red pipe on the magnetic red route of pipe line plate, corresponding magnetic red pipe is provided with the push button of magnet carrier on the stack shell outer wall, the magnetic force that magnet produces when push button is mobile in push button mechanism is to magnetic red pipe generation effect, and then the break-make of the lighting circuit of control magnetic red route of pipe line plate control, because the magnetic force that magnet produces can see through stack shell and affact on the magnetic red pipe, stack shell can be airtight fully, the sealing property that therefore can keep waterproof flashlight well, and can be because of the long-term phenomenon that the proof mechanism of water fatigue aging takes place of using.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Figure 10, shown in Figure 11, the utility model waterproof flashlight comprises head 1 and stack shell 13, be provided with transparent bluff piece, reflective mirror, small electric bulb and bearing thereof in the head 1, be provided with battery in the stack shell 13, also be provided with magnetic red route of pipe line plate 2 in the stack shell 13, stack shell 13 is airtight to external world mutually, have magnetic red pipe 3 on the magnetic red route of pipe line plate 2, corresponding magnetic red pipe 3 is provided with push button mechanism on stack shell 13 outer walls, has magnet on the push button 4 in the push button mechanism.In the present embodiment, have two magnetic red pipes 3 on the magnetic red route of pipe line plate 2, push button mechanism comprises switch egative film 5, switch dough sheet 6 and push button 4, switch dough sheet 6 is fixed on stack shell 13 outer walls, switch dough sheet 6 central authorities offer through hole 12, switch egative film 5 exposes from through hole 12, switch dough sheet 6 both sides have lug boss 7 respectively, lug boss 7 inboards have chute 8, switch egative film 5 both sides have sidewall 9, sidewall 9 inboard corresponding magnetic red pipes 3 are provided with projection 10, and sidewall 9 inboards are provided with two projections 10 altogether, and switch egative film 5 is arranged between switch dough sheet 6 and the stack shell 13, the sidewall 9 of switch egative film 5 snaps in the lug boss 7, sidewall 9 exposes in chute 8, and the both sides of push button 4 have positive stop hook spare 11, and positive stop hook spare 11 is stuck in the chute 7 and is against on the sidewall 9.When promoting push button 4, the positive stop hook spare 11 of push button 4 slides in chute 8, owing to have two projections 10 on the sidewall 9, positive stop hook spare 11 is subjected to the effect of projection 10 to make push button 4 form three gears, when moving up, push button 4 make positive stop hook spare 11 overcome stopping of projection 10 when arriving the top, positive stop hook spare 11 is between chute 8 tops and the upper process 10, this moment is because the magnet in the push button 4 is nearer from the magnetic red pipe 3 on top, magneticaction is to last magnetic red pipe 3, and magnetic red route of pipe line plate 2 is connected lighting circuit under the adhesive effect of magnetic force; Make positive stop hook spare 11 overcome stopping of upper process 10 when moving between two projections 10 when push button 4 moves down, the magnet in the push button 4 is all distant from two magnetic red pipes 3, and magnetic force can't arrive, and at this moment the lighting circuit of flashlight disconnects; When continuing to move down, push button 4 make positive stop hook spare 11 overcome stopping of lower process 10 when moving between lower process 10 and chute 8 bottoms, the magnetic red pipe 3 of push button 4 relative bottoms is nearer, magnetic force can affact down on the magnetic red pipe 3, magnetic red route of pipe line plate 2 is connected lighting circuit under the adhesive effect of magnetic force, and the different brightness that can control the lamp pearl at these two magnetic red pipes 3 respectively form gear.
