The mounting structure of rechargeable battery in light fixture
Technical field
The utility model relates to the light fixture that uses rechargeable battery, refers more particularly to the mounting structure of rechargeable battery in a kind of light fixture of conveniently replaced battery.
Background technology
When design LED watertight light fitting product, in order to reach the classification of waterproof of standard, usually all adopt hermetically sealed design, by built-in rechargeable battery power supply.Then, no matter rechargeable battery is Ni-MH battery or lithium battery, and all arranged service life, namely discharges and recharges the number of times restriction.Present watertight light fitting, as shown in Figure 1, its lamp socket 101 all bonds together with seccotine usually with lampshade 103, make must pull down from lamp socket 101 for install rechargeable battery to be filled housing 102 very difficult, when rechargeable battery expires service life, when needing to change battery, can only adopt cutter carefully to destroy adhesive linkage between lampshade and lamp socket, lampshade is separated with lamp socket, then lampshade is opened.Yet, usually can not guarantee the integrality of lampshade and lamp socket after separation, battery is finished changing, lampshade and lamp socket is again bonding after, more or less can affect its sealing; Because the price of watertight light fitting is usually more expensive, if after battery expires, directly this light fixture is scrapped, waste too large.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of do not open lampshade just can change battery and also can not affect the sealing of light fixture and the normal light fixture that uses in the mounting structure of rechargeable battery.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the mounting structure of rechargeable battery in light fixture, comprise: the housing that filled that is used for the battery case of installation rechargeable battery and is used for installing battery case, being filled housing comprises: base is provided with the sealing ring that offers bellmouth with matching on this base; Described battery case comprises: the cassette holder that lateral wall matches with the bellmouth of sealing ring, cassette holder is arranged in sealing ring, offers the battery chamber that matches with rechargeable battery on cassette holder, and in the battery chamber, sealing is provided with battery cover, and whole battery case is retracted within described base.
Fixed form between described base and sealing ring is: the fixing hole that offers at least one pair of perforation on the end face of described sealing ring, described base offer on itself and the contacted end face of sealing ring with sealing ring on fixing hole corresponding matching and the fixing hole that connects one by one, will pass fixing hole corresponding on base and sealing ring and nut with the bolt that fixing hole matches and be set together.
Described battery chamber is set together by sealing ring and battery cover.
The bottom surface of described base is provided with inside depression at the position at each fixing hole place, makes between adjacent in twos depression and forms the support portion.
Be provided with magnetic attracting mechanism between described battery case and supporting charger.
Described magnetic attracting mechanism comprises: be provided with on described cassette holder with charger shell on magnet corresponding and opposite polarity magnet one by one.
The beneficial effects of the utility model are: the utility model is arranged on battery cover in the battery chamber by being opened in the battery chamber that matches on its cassette holder, with rechargeable battery and sealing, can not open lampshade, directly open battery case and just can change battery, thereby can not affect the sealing of light fixture; Simultaneously, because whole battery case is retracted within described base, can not affect the supporting role of base, thereby can not affect the normal use of whole light fixture.In addition, the support portion that is recessed to form on base has been saved material on the one hand, make on the other hand this support portion can more stably support light fixture, and the bolt cap that also can be used in the bolt of fixed lamp-socket and lampshade is hidden in corresponding depression, can not affect the support of base at all.In addition, be arranged on the battery cover inner surface with charger shell on magnet corresponding and opposite polarity magnet one by one, can be so that the charging of light fixture be convenient.

The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail:
As shown in Figures 2 and 3, the mounting structure of rechargeable battery in light fixture described in the utility model, comprise for the battery case that rechargeable battery is installed and the housing that filled that is used for installing battery case, this is filled the base 1 that housing comprises hollow, is provided with the sealing ring 2 that offers bellmouth with matching on base 1; Described battery case comprises: cassette holder 3, the taper surface of the lateral wall of cassette holder 3 for matching with the hole wall of the bellmouth of described sealing ring 2, cassette holder 3 is arranged in the bellmouth of sealing ring 2, the hole wall of the bellmouth of its lateral wall and sealing ring 2 sticks together, offer the battery chamber that matches with rechargeable battery on cassette holder 3, the battery chamber is provided with battery cover 6 by sealing ring 5 sealings, and whole battery case is retracted within described base 1, thereby can not affect the support of base 1.In the present embodiment, fixed form between described base 1 and sealing ring 2 is: the fixing hole 21 that offers four perforations on the end face of sealing ring 2, base 1 also offer on itself and the contacted end face of sealing ring 2 four with sealing ring 2 on fixing hole 21 corresponding matching and the fixing hole 12 that connects one by one, four bolts are passed respectively fixing hole corresponding on screwed hole 12 on base 1 and sealing ring 2 21 and nut be set together (bolt, nut are usual structure, and be not shown in FIG.); The bottom surface of described base 1 is provided with inside depression 11 at the position at four fixing hole 12 places, makes and forms support portion 13 between adjacent in twos depression 11; Be provided with magnetic attracting mechanism between described battery cover 6 and supporting charger 7, its structure comprises: be provided with the magnet corresponding and opposite polarity magnet 4 one by one in the second placing chamber 73 with charger 7 housings on cassette holder 3, its concrete set-up mode is: be provided with on described cassette holder 3 and magnet 4 the first placing chamber 31 one to one, every block of magnet 4 is placed in corresponding the first placing chamber 31.
During installation, at first the cassette holder 3 with battery case is shelved on base 1, then, sealing ring 2 is covered on cassette holder 3, and by bolt and nut, sealing ring 2 is fixed on base 1, makes cassette holder 3 be fixed in the bellmouth of sealing ring 2; Then, by sealing ring 5, battery cover 6 is arranged on cassette holder 3, and is screwed.
During charging, owing to being provided with magnetic attracting mechanism between battery cover 6 and supporting charger 7, as long as with the close base 1 of charger 7, the charging protuberance that is equipped with central spring thimble 71 and eccentric spring thimble 72 of charger 7 can be drawn to battery cover 6 outer surfaces automatically, make the central spring thimble 71 of charger 7 and eccentric spring thimble 72 contact with the central contact 61 that is arranged on battery cover 6 outer surface centers with ring-type contact 62 centered by central contact 61 respectively, realize that 7 pairs of rechargeable batteries that are arranged in battery case of charger charge.
In use, expire when the service life of rechargeable battery, when needing to change battery, only need to open battery cover 6, change new rechargeable battery, then, then the battery cover 6 that closes gets final product.
