Abstract
The utility model relates to a battery protective sleeve used for an electric torch to prevent that effluent liquid which is caused by a putrefied battery contact the inner shell of the electric torch, and is characterized in that a sealing sleeve circle and a battery sleeve are made of transparent hard plastics. The bottom of the battery sleeve is provided with a conducting device. When the utility model is used, the battery is put in the battery sleeve. An upper section of the battery is sleeved in the sealing sleeve circle first to lead the battery in the battery sleeve to be sealed to delay the chemical reaction of the battery. Even if the effluent liquid which is caused the battery which is putrefied can not contact the shell of the electric torch, the service life of the battery and the electric torch is extended.
Description
The utility model relates to a kind of parts that the flashlight of battery is housed, and specifically a kind of liquid that can prevent that the battery corruption from flowing out is run into the battery protective jacket of torch inner casing.
Known flashlight all is that battery is directly packed in the torch.In the use, because battery without sealing, has been accelerated its chemical reaction, after using a period of time, battery corruption trickle is run into the torch inner casing makes its damages of getting rusty very soon, and the flashlight after getting rusty is also because of loose contact influences result of use, thus shortening battery and flashlight service life.
The purpose of this utility model is to provide a kind of can postpone the battery corruption, prevents that the liquid after the battery corruption from flowing out the protective device that contacts the torch housing.
The purpose of this utility model is achieved in that with the transparent plastic of hardness is arranged be material, makes tubular sealing shroud and battery cover.The sealing shroud internal diameter equates with the battery girth diameter, height 1～2cm.Battery cover flat opening suitable for reading, the lower seal bottom, bottom center leaves a duck eye electric installation is installed.Battery cover external diameter is slightly smaller than torch shell internal diameter, and internal diameter is identical with the sealing shroud external diameter, the short 1～3cm of aspect ratio 1 or 2 or 3 batteries.
State in realization in the process of purpose, electric installation is to fix from central duck eye by one group of conducting metal screw from the battery cover with a conducting metal disk that leaves corresponding duck eye that is slightly smaller than battery cover end circle at the end.
The utility model adopts such scheme to prepare the battery protective jacket.During use, earlier battery is put into protective jacket, puts it into again in the torch, at this moment, above a batteries make cell sealing in the cover by sealing shroud, slowed down the corruption of battery in the cover, prolonged the life-span of battery.When battery corruption trickle, also can not flow out corrosion torch housing because of the isolation of protective jacket.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the side view of an embodiment of the present utility model.
Fig. 2 is the exploded view of Fig. 1 electric installation.
Among the figure 1, battery 2, sealing ring 3, battery cover 4, copper current-conducting piece 5, screw 6, nut.
In the drawings: make internal diameter φ 33mm respectively with polyethylene or polyvinyl chloride or polyamine fat, external diameter φ 34mm, the sealing ring of high 17mm (2) and high 105mm, internal diameter φ 34mm, the battery cover (3) of external diameter φ 35mm is fixed on copper current-conducting piece (4) by screw (5) and nut (6) in the bottom center duck eye of battery cover (3) at the end.During use, battery of a joint is put into battery cover (3) earlier, another is saved put into battery cover (3) after battery (1) is inserted in sealing ring (2) again, sealing ring (2) major part is goed deep in the battery cover (3).The protective sleeve that battery is housed is put into torch, and at this moment, the screw (5) in the protective sleeve contacts with battery bottom, and copper current-conducting piece (4) contacts with torch afterbody lid.
Claims (5)
1, a kind of flash-light battery protective jacket, it is characterized in that with transparent mould firmly for material make the sealing ring (2) of the battery that can be locked and suitable for readingly flat open, the battery cover (3) of lower seal bottom, the sealing ring (2) of can packing into, electric installation is equipped with in the bottom of battery cover (3).
2, according to the described device of claim 1, it is characterized in that the aspect ratio 1 or the short 1～3cm of 2 or 3 batteries of battery cover (3), internal diameter equates that with sealing ring (2) external diameter external diameter is slightly smaller than torch shell internal diameter.
3,, it is characterized in that the height of sealing ring (2) is 1～2cm, wall thickness 0.7～1.5mm according to the described device of claim 1.
4, according to the described device of claim 1, it is characterized in that leaving a duck eye in the bottom center of battery cover, there is the conductive metal sheet that is slightly smaller than battery cover (3) end circle of corresponding duck eye to be fixed on the battery cover by one group of conducting metal screw with one in the hole at the end.
5,, it is characterized in that described conductive metal sheet is that the employing metallic copper is a material according to the described device of claim 4.
