For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the embodiment of the present invention and accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.It should be noted that, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment
Refer to Fig. 1, the invention discloses a kind of safety utilization of electric power socket, comprise protecgulum and the box body 1 of combination installation mutually; Box body 1 is square box-like, and the back side of box body 1 is provided with string holes 2; Protecgulum comprises cover plate 3, spiral cover 6 and brushgear 5; Cover plate 3 is square, and cover plate 3 is provided with at least one columniform cavity 4 set to the concave, and cavity 4 back is provided with cabling hollow out and centre bore, and cover plate 3 is covered on the front of box body 1; Spiral cover 6 is rounded, and spiral cover 6 is provided with the jack matched with plug, and the back side of spiral cover 6 is provided with rotating shaft 7 vertically, and the cavity 4 that spiral cover 6 is covered on cover plate 3 is plugged in the centre bore of cavity 4 by rotating shaft 7; The cavity 4 that cover plate 3 is located at by brushgear 5 is inner, hollow in the middle part of brushgear 5, the rotating shaft 7 of spiral cover 6 is plugged in the centre bore of cavity 4 through brushgear 5, the front of brushgear 5 is provided with the jack matched with plug, the back side of brushgear 5 is electrically connected with civil power, and the electrical connection between the jack of brushgear 5 and civil power triggers and triggers for rotating.
The present invention and the maximum difference of prior art are to have increased brushgear 5 newly, and under normal condition, civil power jack that is real and brushgear 5 is connected.General electrical socket civil power is directly connected by electric wire and jack, thus can there is certain contact risk.Such as baby is thus curious and finger is stretched into the firewire jack of socket, child at oneself inserted sheet etc. by hand false touch plug in the process of the plug insertion socket of electrical appliance.
Refer to Fig. 2, as preferably, described brushgear 5 comprises holder 8, active unit 9, torque spring, brush plate, conducting strip, spring and jacking block 10, holder 8 is in disc, and its back is provided with the groove matched with cavity 4 back of cover plate 3, and groove is arranged in the back of cavity 4, the middle part hollow of holder 8, and the positive Middle face of holder 8 is provided with one 90 ° fan-shaped projections, hollow in the middle part of active unit 9, the front of active unit 9 is provided with the jack matched with plug, conducting strip to be fixed within jack and to be through to the back side of active unit 9, the semi-circular groove of 180 ° is provided with in the middle part of the back side of active unit 9, active unit 9 is coaxially arranged at the front of holder 8 and semi-circular groove is sheathed on the projection of holder 8, active unit 9 is connected to the front of holder 8 by torque spring turnable elastic, the jack back side of active unit 9 is provided with inner cavity, the bottom surface of inner cavity is less than the length of the inserted sheet of electrical appliance plug to the distance between active unit 9 front, two panels brush plate to be fixed on holder 8 and to be positioned in the orientation of international 90 ° of rotation of jack, and the live wire of civil power is electrically connected with two panels brush plate respectively with zero line, the front of holder 8 is provided with cylindrical shaft to the mounting groove caved in, mounting groove is right against in the orientation of rotational trajectory 90 ° of the jack of active unit 9, jacking block 10 is located in the mounting groove of holder 8, spring is provided with between jacking block 10 and the bottom of mounting groove, the head of jacking block 10 protrudes from the front of holder 8, and the head of jacking block 10 is provided with inclined-plane on the rotational trajectory direction of jack, the rotating shaft 7 of spiral cover 6 is plugged in the centre bore of the cavity 4 of cover plate 3 through the hollow in the middle part of active unit 9 and holder 8.
Operation principle of the present invention is: when the plug of electrical appliance is inserted jack, the active unit 9 of brushgear 5 is in normal position, brush plate is positioned in the orientation of international 90 ° of rotation of jack, and be not thus also electrically connected with the conducting strip of jack, civil power can not access the conducting strip of jack.Meanwhile, because the bottom surface of the inner cavity of active unit 9 to be less than the length of the inserted sheet of electrical appliance plug to the distance between active unit 9 front, thus after the plug insertion socket of electrical appliance, inserted sheet is the bottom surface exposing to inner cavity a little.
Now, user only needs plug to screw 90 °, and spiral cover 6 can with plug half-twist, and active unit 9 also can half-twist and the conducting strip in jack is engaged with the brush plate of holder 8 together, civil power is linked into conducting strip by brush plate, thus the energy supply of access plug is to electrical appliance.Now active unit 9 is that the elastic force overcoming torque spring is forced to rotate, and when in rotary course, the inserted sheet of plug streaks the inclined-plane of jacking block 10, jacking block 10 is made to overcome the elastic force first inwardly motion of spring, after active unit 9 rotates to 90 °, jacking block 10 resets under the elastic force effect of spring, and has withstood inserted sheet, stops inserted sheet and active unit 9 to reset and rotates.Meanwhile, the projection of holder 8 is in the semi-circular groove of active unit 9, and the side of semi-circular groove can be withstood in the side of projection, plays position-limiting action to active unit 9, and what prevent active unit 9 rotates over 90 °.
After user pulls the plug out of the socket, jacking block 10, not on the inserted sheet acting on plug, then causes active unit 9 also lose coupling mechanism force and reset under the effect of torque spring, makes brush plate be separated power-off with conducting strip thereupon.
In said process, plug is exactly " key " of opening electrical safety socket of the present invention, cannot screw active unit 9 brush plate and conducting strip are connected under the prerequisite not inserting socket from outside.Therefore, when active unit 9 is in normal position, be also perfectly safe even if allow human body contact with conducting strip.On the contrary, after plug is extracted, active unit 9 also can reset at once, has stopped the danger of contact.
As preferably, the sidewall of described box body 1 is provided with back-off groove, and the side of cover plate 3 is provided with back-off tooth, and the back-off tooth of cover plate 3 is buckled and is located in the back-off groove of box body 1.Adopt non-bolted joint between cover plate 3 and box body 1, install more convenient, product is more attractive in appearance.
As preferably, rotating shaft 7 end of described spiral cover 6 is provided with back-off tooth, and spiral cover 6 is connected to the centre bore of the cavity 4 of cover plate 3 by back-off eye cutting.The inserting mode of spiral cover 6 also adopts non-bolted joint, convenient installation.
A kind of safety utilization of electric power socket provided by the present invention, the energising of socket needs user initiatively to complete, initiatively screw and can be energized after must inserting plug, guarantee to get an electric shock in the process inserting plug or under the state of no-pin plug, and auto-breaking after pulling the plug out of the socket.Meanwhile, easy to use, substantially identical with the using method of common socket.
The above embodiment only have expressed one embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
