[0030] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
[0032] Embodiment 1:
[0033] This embodiment relates to a socket with a safety door, such as Figure 1-5 As shown, it includes: a socket bottom box 100, a two-pole safety slider 200, a three-pole safety slider 300 and an elastic member 400.
[0034] Among them, Figure 1-2 As shown in Figure 4, the bottom of the socket bottom box 100 is provided with a two-pole jack 110 and a three-pole jack, and the three-pole jack includes: a positive and negative jack 120 and a grounding jack 130, and the grounding jack 130 is arranged in the middle of the two-pole jack 110, so that the two-pole jack 110 and the three-pole jack form a five-hole with a compact design, and the socket as a whole is more compact. A guide groove 600 is also arranged on the upper surface of the bottom of the socket bottom box 100, and the guide groove 600 extends parallel to the center line direction of the two-pole jack 110, that is, extends from the two-pole jack 110 to the positive and negative jack 120.
[0035] like Figure 3 , 5As shown, the two-pole safety slider 200 is made of insulating material and is arranged inside the socket bottom box 100 and above the two-pole socket 110, so as to shield the two-pole socket 110 below and insulate it, so as to prevent the external direct connection with the power supply in the two-pole socket 110 and cause electric shock; a grounding hole 210 is provided in the middle of the two-pole safety slider 200 for exposing the grounding socket 130, so as to facilitate the external direct connection with the grounding socket 130, and the inside of the grounding socket 130 is not electrified, so there is no risk of leakage or electric shock; a first sliding block 250 is provided at the bottom of the two-pole safety slider 200, and the first sliding block 250 cooperates with the guide groove 600 to install the two-pole safety slider 200 on the guide groove 600, so that the two-pole safety slider 200 can slide along the guide groove 600. The three-pole safety slider 300 is also made of insulating material and is arranged inside the socket base box 100 and above the positive and negative sockets 120. It is used to shield the positive and negative sockets 120 below and insulate them to prevent the outside from directly conducting with the power supply in the positive and negative sockets 120 and causing electric shock. A second sliding block 340 is arranged at the bottom of the three-pole safety slider 300. The second sliding block 340 cooperates with the guide groove 600 to install the two-pole safety slider 200 to the other end of the two-pole safety slider 200 on the guide groove 600, so that the three-pole safety slider 300 can slide along the guide groove 600.
[0036] like Figure 1 , 2 As shown, the elastic member 400 is disposed between the two-pole safety slider 200 and the three-pole safety slider 300 to push the two-pole safety slider 200 and the three-pole safety slider 300 to the two ends of the guide groove 600 to shield the two-pole socket 110 and the positive and negative sockets 120, thereby achieving a good anti-electric shock effect.
[0037] like Figure 3 As shown, first inclined surfaces 220 are provided on both sides above the two-pole safety slider 200 corresponding to the positions of the two-pole socket 110. The first inclined surfaces 220 are inclined surfaces that are away from the three-pole safety slider 300 and are inclined downward. When the pin of the two-pole plug is inserted into the first inclined surface 220, the pin will push the two-pole safety slider 200 to slide along the guide groove 600 in the direction of the three-pole safety slider 300 and away from the top of the two-pole socket 110 through the first inclined surface 220, and compress the elastic member 400, so that the two-pole plug is smoothly inserted into the two-pole socket 110; when the two-pole plug is pulled out of the two-pole socket 110 on the socket, the elastic member 400 will push the two-pole safety slider 200 to reset to the top of the two-pole socket 110, so as to shield and insulate the two-pole socket 110.
[0038] A second inclined surface 310 is provided on both sides above the three-pole safety slider 300 corresponding to the positions of the positive and negative sockets 120. The second inclined surface 310 is an inclined surface inclined downwardly and away from the two-pole safety slider 200. When the positive and negative pins of the three-pole plug are inserted into the second inclined surface 310, the positive and negative pins will push the three-pole safety slider 300 to slide along the guide groove 600 toward the two-pole safety slider 200 and away from the top of the positive and negative sockets 120 through the second inclined surface 310, and compress the elastic member 400, so that the positive and negative plugs can be smoothly inserted into the positive and negative sockets 120. The grounding pin of the three-pole plug can be connected to the grounding socket 130 through the grounding hole 210 on the two-pole safety slider 200, so as to realize the plug-in of the three-pole plug 300. When the three-pole plug is pulled out from the positive and negative sockets 120 on the socket, the elastic member 400 will push the three-pole safety slider 300 to return to the top of the positive and negative sockets 120 to shield and insulate the two-pole socket 110 .
[0039] The two-pole safety slider 200 and the three-pole safety slider 300 are both installed in the socket bottom box 100 through the guide groove 600, so that the two-pole safety slider 200 and the three-pole safety slider 300 can slide in the socket bottom box 100, and the guide groove 600 can guide the sliding of the safety slider, ensuring the sliding stability and smoothness of the safety slider. The socket pin does not need much force to insert into the safety door, and the plug can be smoothly plugged into the socket. As a preferred solution, the guide groove 600 is set as a semicircular guide groove, and the first sliding block 250 and the second sliding block 340 are set as semicircular sliding blocks that match well with the semicircular guide groove. The semicircular sliding block is concentrically matched with the semicircular sliding groove, so that the two-pole safety slider 200 and the three-pole safety slider 300 can slide more smoothly in the socket bottom box 100, and the socket is more convenient and easy to use.
[0040] like Figure 4 As shown, in this embodiment, only one group of guide grooves 600 is provided, extending along the center line direction of the two-pole plug hole 110. The middle of the two-pole safety slider 200 and the three-pole safety slider 300 is guided to ensure the balance of the two-pole safety slider 200 and the three-pole safety slider 300, and achieve a good guiding effect.
[0041] The upper sides of the two-pole safety slider 200 and the three-pole safety slider 300 are both provided with inclined surfaces, and the moving direction of the safety slider is perpendicular to the direction of the two-pole socket 110 and the two-side sockets of the positive and negative sockets 120. The pins need to be inserted into the sockets on both sides at the same time to open the safety door more easily, thereby improving the safety factor of the socket and reducing the possibility of accidental electric shock.
[0042] As a preferred solution, an anti-misinsertion limit block 500 is provided at the bottom of the socket bottom box 100 and between the two-pole safety slider 200 and the three-pole safety slider 300. Two groups of anti-misinsertion limit blocks 500 are provided, symmetrically arranged on the left and right sides of the center line of the two-pole socket 110. When the socket is mis-inserted or wrongly inserted, and only the inclined surface on one side of the safety slider is subjected to external force, the safety slider will tilt toward the side subjected to force, and the anti-misinsertion limit block will block the safety slider to prevent the safety slider from sliding away from the corresponding socket. The anti-misinsertion limit block 500 can avoid accidental electric shock caused by the safety slider sliding open and inserted into the socket due to the insertion of foreign objects on one side, thereby improving the safety factor of the socket and reducing the possibility of accidental electric shock. In this embodiment, the anti-misinsertion limit block 500 is extended in a direction parallel to the guide groove 600, and the anti-misinsertion limit block 500 cooperates with the bottom of the two-pole safety slider 200 and the three-pole safety slider 300 to support the bottom of the two-pole safety slider 200 and / or the three-pole safety slider 300 when the safety slider slides out, thereby preventing the two-pole safety slider 200 and the three-pole safety slider 300 from tilting to one side during the sliding process, thereby affecting the sliding smoothness and even causing the safety slider to be unable to reset.
[0043] Of course, in other embodiments, the guide grooves 600 may also be arranged at other positions, or two groups may be arranged symmetrically on both sides of the center line of the two-pole socket 110, so that the two-pole safety slider 200 and the three-pole safety slider 300 can slide more smoothly and balanced.
[0044] In this embodiment, the elastic member 400 is configured as a spring, and one end of the elastic member 400 abuts against the two-pole safety slider 200, and the other end abuts against the three-pole safety slider 300, so as to push the safety sliders on both sides. The elastic member 400 is arranged along the center line of the two-pole socket 110, so that the two ends of the elastic member 400 abut against the middle of the safety slider, which can better act on the safety slider, while ensuring the balance of the action on the safety slider, so that only when plugs are inserted on both sides can the safety slider be pushed to move, which is safer. Of course, in other embodiments, the elastic member 400 can also be provided in two groups, symmetrically arranged on the left and right sides of the center line of the two-pole socket 110. As a preferred solution, Figure 3 As shown, the two-pole safety slider 200 is provided with a first mounting column 230 for mounting the elastic member 400, and the three-pole safety slider 300 is provided with a second mounting column 320 for mounting the elastic member 400, so as to improve the installation stability of the elastic member 400 and ensure the good effect and correct action direction of the elastic member 400.
[0045] As a preferred solution, Figure 5As shown, a plug-in block 240 is provided on one side of the two-pole safety slider 200 close to the three-pole safety slider 300, and a plug-in hole 330 cooperating with the plug-in block 240 is provided on the three-pole safety slider 300. When the plug is inserted into the two-pole jack 110 or the three-pole jack, the two-pole safety slider 200 or the three-pole safety slider 300 will slide along the guide groove 600, so that the plug-in hole 330 and the plug-in block 240 are matched, ensuring the stability of the two-pole safety slider 200 and the three-pole safety slider 300, and achieving a good plug-in effect between the plug and the socket. At the same time, the plug-in block 240 is also the part of the two-pole safety slider 200 used to cover the two-pole jack 110, and the three-pole safety slider 300 above the plug-in hole 330 can also cover the positive and negative jacks 12, and the plug-in hole 330 and the plug-in block 240 are mutually matched, which can reduce the volume of the safety slider and optimize the internal space of the socket.
[0046] In this embodiment, if Figure 4 As shown, a first anti-slip block 140 is provided on the socket bottom box 100 and above the two-pole socket 110. The first anti-slip block 140 can prevent the two-pole safety slider 200 from slipping out from above the two-pole socket 110, thereby affecting the protective effect of the two-pole safety slider 200. A second anti-slip block 150 is provided on the socket bottom box 100 and above the positive and negative sockets 120. The second anti-slip block 150 can prevent the three-pole safety slider 300 from slipping out from above the positive and negative sockets 120, thereby affecting the protective effect of the three-pole safety slider 300. However, no anti-slip block is provided above the middle of the two-pole socket 110 and the positive and negative sockets 120, thereby facilitating the installation of the two-pole safety slider 200 and the three-pole safety slider 300 into the socket bottom box 100, thereby making the assembly of the socket more convenient. When the socket is inverted during installation, the first anti-slip block 140 and the second anti-slip block 150 can prevent the two-pole safety slider 200 and the three-pole safety slider 300 from slipping out, making the installation process more convenient.
[0047] Embodiment 2:
[0048] This embodiment relates to a socket with a safety door, which is different from the above-mentioned embodiment 1 in that only one safety slider, a two-pole safety slider 200 or a three-pole safety slider 300, is provided inside the socket bottom box 100, which is provided above the corresponding socket in the socket bottom box. The configuration of the socket at the bottom of the socket bottom box 100 may also be different from that in the embodiment 1.
[0049] One end of the elastic member 400 abuts against the socket bottom box 100, and the other end abuts against the safety slider to push the safety slider to the top of the socket. A sliding block is provided at the bottom of the safety slider, and the sliding block cooperates with the guide groove to install the safety slider on the guide groove 600, so that the safety slider can slide in the socket bottom box, ensuring the stability and smoothness of the sliding of the safety slider, and facilitating the opening and closing of the safety door.
[0050] The above is only used to illustrate the technical solution of the utility model rather than to limit it.
