Abstract

The utility model discloses a rechargeable flashlight which comprises a rear cover, wherein the rear cover is arranged at the rear end of a flashlight body; a charging plug is arranged at the inner side of the rear cover and is connected with the anode and the cathode at the rear end of a rechargeable battery in the flashlight body through a positive electrode and a negative electrode; a charging hole is formed in the side wall of the rear cover; a sleeve body which is capable of sliding along the axial line of the rear cover and shielding the charging hole is sheathed on the rear cover; and the sleeve body is capable of exposing the charging hole after sliding backwards. When the rechargeable flashlight is in normal use, the charging hole is shielded by the sleeve body to prevent filths such as dust, grease and the like from entering the charging hole to cause bad contact; when charging is required, the sleeve body is pushed backwards to ensure that the sleeve body moves backwards along the axial line of the rear cover until the charging hole is exposed, and then the flashlight can be charged; and after the charging is finished, the sleeve body is pushed back until the charging hole is shielded, so that the operation is very convenient.

Description

A kind of chargeable flashlight

Technical field

The utility model relates to a kind of flashlight, particularly a kind of chargeable flashlight.

Background technology

Chargeable flashlight is a kind of energy-saving flashlight that uses rechargeable battery (dry cell), and it can charge to the battery in its stack shell and use through charger repeatedly, has solved the problem that traditional flashlight needs often to change battery, helps protecting environmental resource.Existing chargeable flashlight generally comprises the stack shell that is used to install battery, son, tube cover, light source and bonnet are inserted in the charging that is used for that rechargeable battery is charged, and the slotting son of charging places stack shell inboard, and charging Kong Zekai is at the sidewall of stack shell; But get in it because the charging hole is exposed to the outer dirts such as extraneous dust, grease that make easily, cause loose contact, institute thinks and prevents to influence charging performance because of dirt gets into; The prior art hole of will charging is arranged on the stack shell front portion; And can be when chargeable flashlight normally uses by the rear portion of the tube cover maskaperture mask that will charge, get into the charging hole to prevent dirt, and cross a step ground; For preventing that liquid from getting into the charging hole; Also the rearward position of corresponding stack shell is provided with groove water proof ring is installed in the charging hole, when the tube cover covers the charging hole, and water proof ring and the tube cover inwall formation watertight that offsets.Though but this type of chargeable flashlight can will charge maskaperture mask with dustproof, waterproof under normal situation about using, need the tube cover be unscrewed forward to expose the charging hole before its charging, the tube cover of backward screwing again after charging, obviously, operation is very inconvenient.

Summary of the invention

The purpose of the utility model is to provide a kind of prevents dust, waterproof and chargeable flashlight easy to use.

The described chargeable flashlight of the utility model; Comprise the bonnet that is installed in the stack shell rear end; The slotting son of charging is equipped with in the inboard of described bonnet, and the positive and negative electrode that the slotting son of charging passes through the rechargeable battery rear end in positive and negative electrode and the stack shell is connected, and the sidewall of bonnet has the charging hole; Described bonnet is set with to slide along the axis of bonnet and also can covers the body in charging hole, can the charging hole be exposed after body slides backward.

The utility model is because the slotting son that will charge is arranged on bonnet with the charging hole; And on bonnet, be set with and slide and be used to cover the body in charging hole along the axis of bonnet; During normal the use, the body maskaperture mask that will charge causes loose contact to prevent dirts entering such as dust, grease in it; And when needing charging, then can promote body backward, and body is moved to behind the axis of bonnet expose the charging hole and can flashlight be charged, and the past rightabout in the back of charge gets final product the position that body pushes back to the maskaperture mask that charges, operation is very easy.
