Abstract
The utility model discloses a three-hole safety socket, which comprises a three-hole socket body, an upper cover in clamping connection with the socket body and provided with jacks, a rest spring, and a sliding block arranged between the upper cover and the socket body to cover a live-line jack and a zero-line jack on the socket body. The lower surface of the sliding block is provided with strip-shaped flanges. When an electric conductor is mistakenly inserted into the live-line jack or the zero-line jack on the upper cover, the sliding block is compelled to be inclined by means of the strip-shaped flanges. The arrangement direction of the flanges is the same with the sliding direction of the sliding block. The inner walls of the live-line jack and the zero-line jack on the upper cover are provided with a groove respectively. Under the inclined state of the sliding block, the tilting end of the sliding block is trapped in the grooves, so that the sliding block cannot move any more. Due to the adoption of the three-hole safety socket, electric shock accidents resulted from the misoperation of inserting an electric conductor into only one jack of the socket by mistake can be effectively prevented. Therefore, the three-hole safety socket is of great significance especially for families with children.
Description
Technical field
The utility model relates to a kind of three safety sockets.
Background technology
Three common sockets comprise live wire, zero line and ground wire jack, although the socket that has is provided with the sliding shoe that covers in live wire and zero line jack on the jack body between loam cake and jack body, but empty table is arranged on foot just, when people's mistake is firmly inserted jack with the electric conductor single hole, still electric conductor might be inserted in the firewire jack on the jack body, electric shock accidents meets accident.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of three safety sockets of protection against electric shock are provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of three safety sockets, comprise three jack bodies, be connected on the jack body and offer the loam cake of jack, back-moving spring, be arranged on the sliding shoe that covers in live wire and zero line jack on the jack body between loam cake and jack body, the sliding shoe bottom surface is provided with the strip flange that forces sliding shoe to tilt when mistake is inserted loam cake live wire or zero line jack with electric conductor, the trend of flange is identical with the glide direction of sliding shoe, is provided with on loam cake live wire and the zero line jack place inwall because the sliding shoe inclination causes sliding shoe perk end to be absorbed in and causes the irremovable groove of sliding shoe.
Back-moving spring one end is fixed on the sliding shoe, and the other end is fixed on the loam cake inwall.
The cross sectional shape of flange is triangle.
The beneficial effects of the utility model are: three safety sockets that the utility model provides can effectively prevent the generation because of the electric shock accidents that the simple eye insertion socket of electric conductor is caused by mistake, and are especially significant to the family that child is arranged in the family.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of loam cake.
Fig. 3 is the front view of sliding shoe.
Fig. 4 is the left view of Fig. 3.
Among the figure: 1. jack body; 2. loam cake; 3. sliding shoe; 4. inclined-plane; 5. back-moving spring; 6. groove; 7. spring base; 8. flange; 9. pin.
Embodiment
By reference to the accompanying drawings the utility model is further described now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of three safety sockets as shown in Figure 1, comprise three jack bodies 1, be connected on the jack body 1 and offer jack loam cake 2, back-moving spring 5, be arranged on the sliding shoe 3 that loam cake 2 and 1 of jack body cover in live wire and zero line jack on the jack body 1, the inclined-plane 4 on the sliding shoe 3 is corresponding with live wire and zero line jack on the loam cake 2.Such as Fig. 3, shown in Figure 4: sliding shoe 3 bottom surfaces are provided with strip flange 8, the cross sectional shape of flange 8 is triangle, the trend of flange 8 is identical with the glide direction of sliding shoe 3, as shown in Figure 2: be provided with groove 6 on loam cake 2 live wires and the zero line jack place inwall, when people mistake is inserted into inclined-plane 4 on the sliding shoe 3 with electric conductor by loam cake 2 live wires or zero line jack, to force sliding shoe 3 to tilt, because thereby sliding shoe 3 tilts to cause sliding shoe 3 perk ends to be absorbed in groove 6, cause sliding shoe 3 to move, electric conductor also just can't enter live wire and the zero line jack on the jack body 1 like this.When people insert three safety sockets with plug, because plug base pin almost is inserted on the inclined-plane 4 on loam cake live wire and the zero line jack downslide motion block 3 simultaneously, because the effect on inclined-plane 4, sliding shoe 3 slides, and plug base pin enters live wire and the zero line jack on the jack body 1.Back-moving spring 5 one ends are sleeved on the pin 9 on the sliding shoe 3, the other end is fixed in the spring base 7 on loam cake 2 inwalls, after people extract plug three safety sockets, under the effect of back-moving spring 5, sliding shoe 3 begins to slide, until again cover in live wire and zero line jack on the jack body 1.
Above-mentioned execution mode only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present utility model and is implemented; can not limit protection range of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in the protection range of the present utility model.
Claims (3)
1. three safety sockets, comprise three jack bodies, be connected on the jack body and offer the loam cake of jack, back-moving spring, be arranged on the sliding shoe that covers in live wire and zero line jack on the jack body between loam cake and jack body, it is characterized in that: the sliding shoe bottom surface is provided with the strip flange that forces sliding shoe to tilt when mistake is inserted loam cake live wire or zero line jack with electric conductor, the trend of flange is identical with the glide direction of sliding shoe, is provided with on described loam cake live wire and the zero line jack place inwall because the sliding shoe inclination causes sliding shoe perk end to be absorbed in and causes the irremovable groove of sliding shoe.
2. three safety sockets according to claim 1, it is characterized in that: described back-moving spring one end is fixed on the sliding shoe, and the other end is fixed on the loam cake inwall.
