Abstract
The utility model relates to a waterproof power supply box and belongs to the electrical accessory field. An existing plugging port does not possess a waterproof function, which brings a potential safety hazard for usage of the power supply box. The power supply box of the utility model comprises a box body formed by a front end cap and a rear end cap. The front end cap is provided with an installing port and at least one jack is arranged in the installing port. The front end cap is provided with an embossment which surrounds the installing port. The front end cap is movably connected with a waterproof cover plate which can cover the installing port. An inner side surface of the waterproof cover plate is provided with a groove. When the waterproof cover plate covers the installing port, the embossment is located in the groove. After using the above structure, the power supply box of the utility model possesses multiple defensive lines so as to prevent invasion of water, steam, dust and other impurities. Waterproof and dustproof effects are significant. The function is durable and stable so that usage security is increased and a service life is prolonged.
Description
Technical field
The utility model belongs to the electrical accessorie field, is specifically related to a kind of power pack.
Background technology
Power pack is that people are used for obtaining power supply or controlling by power pack a kind of device that other electrical equipment opens or cuts out when making electrical appliance, usually exist with the single cartridge bodies state, generally be provided with simultaneously interface and switch on power pack, and existing interface does not possess water-proof function, it is long-term outside exposed, not only can be subject to the intrusion of water and steam, also can be subject to the erosion of dust or other impurity, bring potential safety hazard for the use of power pack.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of power pack with water-proof function.
The purpose of this utility model can realize by following technical proposal: a kind of waterproof power pack, comprise the box body that is formed by front end housing and rear end cap, offering an installing port on front end housing and be provided with at least one jack in installing port, it is characterized in that, described front end housing is provided with the projection around described installing port, also be connected with the waterproof cover that can cover described installing port on front end housing, be provided with groove on the waterproof cover medial surface and when waterproof cover covers described installing port described projection be positioned at groove.By waterproof cover is set, the power pack jack is isolated from the outside, both can avoid jack to contact with the direct of water, steam, also can effectively stop entering of dust or other impurity, coordinate again the hermetically-sealed construction of upper projection and groove, can also effectively stop water, steam and dust or other impurity to penetrate into inside from the gap between waterproof cover and front end housing outer surface.
In above-mentioned a kind of waterproof power pack, described waterproof cover edge has turning edge towards installing port.This design can reduce the gap between waterproof cover and front end housing outer surface, then coordinates the hermetically-sealed construction of above-mentioned projection and groove, makes the waterproof and dustproof function of waterproof cover more effective.
In above-mentioned a kind of waterproof power pack, described front end housing is provided with holder and bearing pin, and described waterproof cover forms by bearing pin and holder and is articulated and connected.Adopt this syndeton can easily open or close waterproof cover.
In above-mentioned a kind of waterproof power pack, described bearing pin is provided with torsion spring.Torsion spring gives the active force that waterproof cover covers jack, even when using power pack, need the people for overcoming this active force, waterproof cover to be opened, plug is linked into jack, when pulling out plug, waterproof cover just can cover jack under the torsion spring effect, also make on the other hand waterproof cover tightr with the applying of front end housing outer surface under the torsion spring effect, is difficult for starting a leak.
In above-mentioned a kind of waterproof power pack, described projection is annular protrusion, and described groove is made of two annular ribs and two annular rib concentric circles settings.When waterproof cover is closed, adopt said structure, projection is difficult for dislocation with groove.
In above-mentioned a kind of waterproof power pack, described two annular ribs and waterproof cover are one-body molded.
In above-mentioned a kind of waterproof power pack, described projection and front end housing are one-body molded.
Compared with prior art, after the utility model adopts said structure, possesses the invasion of the anti-sealing of multiple defence line, steam, dust and other impurity, the waterproof and dustproof effect is remarkable, and this function is lasting, stable, thereby improves safety in utilization, and increases the service life.

Fig. 1 is the utility model front view.
Fig. 2 is the utility model left view.
In figure, 1, front end housing; 2, rear end cap; 3, installing port; 4, switch; 5, jack; 6, projection; 7, waterproof cover; 8, rib; 9, groove; 10, turn edge; 11, holder; 12, bearing pin; 13, torsion spring.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As depicted in figs. 1 and 2, a kind of waterproof power pack, its box body is comprised of front end housing 1 and rear end cap 2, has an installing port 3 and a switch 4 on front end housing 1, offers a jack 5 in installing port 3, and annular protrusion 6 is one-body molded and around installing port 3 with front end housing 1.Why projection 6 is made as annular, has eliminated on the one hand because producing corner angle and increase the risk that starts a leak, more smooth-going when making on the other hand annular protrusion 6 enter groove 9 on waterproof cover 7.
The spacing that has 8 of the two annular ribs of annular rib 8, two that and concentric circles one-body molded with waterproof cover 7 arrange on waterproof cover 7 medial surfaces forms the groove 9 that can hold above-mentioned annular protrusion 6, and the edge of waterproof cover 7 has and turns edge 10 towards installing port 3.The setting of waterproof cover 7 both can avoid jack 5 to contact with the direct of steam, water, also can effectively stop entering of dust and other impurity, be on coordinating again integrated protruding 6 with the hermetically-sealed construction of groove 9 and waterproof cover 7 on turn edge 10, make the waterproof and dustproof effect of waterproof cover 7 more remarkable, adopt the structure of sealing ring sealing to compare with tradition, water-proof function is more lasting, stable.
The top that is positioned at jack 5 on front end housing 1 is provided with holder 11 and bearing pin 12, and waterproof cover 7 forms with holder 11 by bearing pin 12 and is articulated and connected, and also is provided with a torsion spring 13 on bearing pin 12.Adopt this syndeton can easily open or close waterproof cover 7, and waterproof cover 7 can be under torsion spring 13 effects after opening autoshutdown, this function also makes waterproof cover 7 fit closelyr with front end housing 1 outer surface under torsion spring 13 effects, is difficult for starting a leak.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
