[0002] Wall sockets are a common type of sockets installed in walls in daily life. The corresponding sockets on existing wall sockets are all open, which poses certain safety hazards. In particular, children or people with weak awareness of electrical safety may insert foreign objects such as wires and metal sheets into the sockets, thereby causing safety accidents.

[0003] The invention patent with application number 2021104384000 discloses an overload protection wall socket with an overload protection function, including a socket body, a plug interface on the socket body, the plug interface including a plurality of sockets one located on the surface of the socket body, a conductive strip matching the socket one installed inside the socket body, a pin holder one provided on the conductive strip, the pin holder one installed at the opening of the socket one, a wire connection device matching the conductive strip installed on the socket body, and the wire connection device and the conductive strip are connected through an overload protection device. The wall socket disclosed in the invention patent has an overload protection function through an overload guarantee device inside the socket body, which effectively prevents the occurrence of fire, but the socket is still open, which is prone to electric shock safety accidents. Therefore, in view of the shortcomings of the existing wall sockets that are open and prone to electric shock safety accidents, this application proposes a wall socket with a safety protection device that can effectively solve the above technical problems. Summary of the invention

[0004] The present invention aims to provide a wall socket with a safety protection device to solve the problem that the existing wall socket is easily prone to electric shock safety accidents due to the open arrangement of the socket.

[0005] The present invention is achieved through the following technical solutions:

[0006] A wall socket with a safety protection device, comprising a socket body, a plug socket is arranged on the front side of the socket body, an insulating panel covering the plug socket is arranged on the front side of the socket body, a circular groove corresponding to the plug socket is opened on the insulating panel, a corresponding hole aligned with the plug socket is opened on the bottom wall of the circular groove, an insulating swivel is rotatably arranged in the circular groove through a positioning shaft and a torsion spring, and a pin hole corresponding to the plug socket is opened on the insulating swivel;

[0007] A radial lock tongue hole connected to each hole position in the pin hole is provided on the outer circumferential surface of the insulating swivel, a lock tongue strip extending into the pin hole is inserted into the radial lock tongue hole, a telescopic receiving groove corresponding to each lock tongue strip is provided on the periphery of the circular groove, a radial channel is provided between the telescopic receiving groove and the circular groove, a locking block is provided in the telescopic receiving groove, an elastic member supporting the locking block toward the circular groove is provided in the telescopic receiving groove, and an end of the locking block passes through the radial channel and extends into the radial lock tongue hole to interact with the lock tongue strip.

[0008] As a further configuration of the above solution, a rectangular groove matching the insulating panel is formed on the front side of the socket body, and the plug socket is arranged in the rectangular groove.

[0009] As a further configuration of the above solution, a plurality of screw holes are provided on the outer edge of the insulating panel, and connecting screws connected to the socket body are provided in the screw holes.

[0010] As a further configuration of the above solution, the lock tongue strip is made of insulating material, and the upper inner end of the lock tongue strip is configured to be an inclined surface with a guiding function.

[0011] As a further configuration of the above solution, the locking block is configured in a T-shaped structure, and one end of the locking block extends along the radial channel into the radial locking tongue hole.

[0012] As a further configuration of the above solution, a protective cover is rotatably connected to the upper end of the socket body, and the lower end of the protective cover is open.

[0013] As a further configuration of the above solution, a plug-in card block is fixed to the top surface of the protective cover, and an elastic card strip that interacts with the plug-in card block is fixed to the upper surface of the socket body.

[0014] The wall socket disclosed in the present invention is provided with a safety protection device on the outside of the plug socket. Before the plug is inserted, the safety protection device rotates the insulating swivel to a certain angle due to the action of the torsion spring, thereby causing the pin hole on the insulating swivel to be misaligned with the plug socket and then sealing them.

[0015] At the same time, the safety protection device in the present invention is further provided with structures such as a lock tongue strip, a locking block, and a spring. Before the wall socket is not used, the locking block is pushed into the radial lock tongue hole of the insulating swivel by the spring, thereby restricting the circumferential rotation of the insulating swivel. Only when all the pins in the matching plug are inserted into the pin holes, the lock tongue strip is moved radially outward by the extrusion effect, and the locking block is pushed out of the radial lock tongue hole. At this time, the circumferential restriction effect of the insulating swivel will be released. At this time, the insulating swivel can be rotated until the plug on the plug is aligned with the plug jack before it can be inserted into the wall socket to realize circuit connection.

[0016] In addition, a protective cover is provided on the socket body, which can provide good dust and water-proof effects when the wall socket is not in use or in use. The protective cover can be flipped up and fixed when plugging and unplugging the plug, making it convenient for users to perform plugging and unplugging operations. Beneficial Effects

[0017] The wall socket disclosed in the present invention is designed with a safety protection device so that when the wall socket is not in use, its plug socket can be sealed by an insulating swivel misalignment, effectively solving the risk of electric shock easily caused by the open socket design in the existing wall socket.

[0018] The safety protection device in the present invention is further provided with a lock tongue strip, a locking block, a spring and other components. Only when all the pins in the plug are inserted into the pin holes in the insulating swivel will the limiting effect of the insulating swivel be released, and then the insulating swivel can be rotated so that the plug can be inserted into the socket to connect the circuit. That is, the corresponding plug is similar to a key for releasing the limitation of the insulating swivel. Only when the user uses the correct plug can the circuit be connected, which greatly avoids the occurrence of electric shock safety accidents and has extremely high safety.

[0019] The present invention further provides a protective cover, so that the wall socket has a good dust and water proof effect when not in use or in long-term use, and is easy for users to operate during the plug insertion and removal process, and has strong practicality.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 9 , and describes the application in detail with reference to embodiments. Example 1

[0032] Embodiment 1 discloses a wall socket with a safety protection device. Figure 1 , Attachment Figure 3 and attached Figure 4 The wall socket includes a socket body 100 and a safety protection device 200. A rectangular groove 101 matching the overall frame of the safety protection device 200 is provided on the front of the socket body 100, and a plug jack 102 is provided in the rectangular groove 101. The specific plug jack 102 can be one or more of a two-pin jack and a three-pin jack, and the number and arrangement of the plug jack 102 can be adjusted according to actual conditions. In this figure, one two-pin jack and one three-pin jack are provided, and the two are arranged at intervals up and down.

[0033] Reference Figure 4 and attached Figure 6The safety protection device 200 includes an insulating panel 201 matching the rectangular groove 101, and a plurality of screw holes 202 are provided at intervals on the outer edge of the insulating panel 201, so that the insulating panel 201 can be fixedly connected to the socket body 100 through the connecting screws in the screw holes 202. A circular groove 203 corresponding to the plug jack 102 is provided on the insulating panel 201, and then a corresponding hole 204 aligned with the plug jack 102 is provided on the bottom wall of the corresponding circular groove 203, so that the pins in the plug can pass through the corresponding hole 204 and be inserted into the plug jack 102, and connect with the contact piece inside the socket body 100, thereby realizing the conduction of the circuit.

[0034] A positioning shaft 205 arranged along its axial direction is connected to the center of the bottom wall of each circular groove 203, and then an insulating rotator 206 matching the circular groove 203 is rotatably connected to the positioning shaft 205, and a torsion spring 207 sleeved on the positioning shaft 205 is connected between the insulating rotator 206 and the bottom wall of the circular groove 203.

[0035] A pin hole 2061 is provided on the insulating rotator 206, and the pin hole 2061 corresponds to the plug socket 102 on the socket body 100. When the insulating rotator 206 is not acted upon by an external force, the pin hole 2061 on the insulating rotator 206, the plug socket 102 on the socket body 100, and the corresponding hole 204 can be rotated and misaligned with each other under the force of the torsion spring 207. At this time, the plug cannot be inserted into the plug socket 102 by directly inserting it into the pin hole 2061.

[0036] When the user needs to connect the plug to the wall socket, the user directly inserts the plug into the corresponding pin hole 2061, and then rotates the insulating swivel 206 to align the pins on the plug with the plug jack 102 on the socket body 100. After alignment, the plug can be inserted into the socket body 100 by pressing it hard to connect the circuit. When not in use, the plug is unplugged, and then the insulating swivel 206 automatically rotates a certain angle under the force of the torsion spring 207, so that the pin hole 2061 and the plug jack 102 are rotated and misaligned with each other, and the plug jack 102 on the socket body 100 is sealed by the insulating swivel 206. Example 2

[0037] Example 2 discloses a wall socket that is further improved based on the technical solution in Example 1, and the similarities between it and Example 1 are not described again.

[0038] Reference Figure 5 , Attachment Figure 6 and attached Figure 7A plurality of radially arranged locking tongue holes 2062 are provided on the outer circumferential surface of the insulating rotator 206 , and the inner end of each locking tongue hole 2062 is connected to the hole position of the pin hole 2061 .

[0039] Taking the two pin through holes 2061 as an example, two locking tongue holes 2062 are provided on the outer circumferential surface of the insulating swivel 206, and the two locking tongue holes 2062 are respectively connected with the inner ends of the two holes of the pin hole 2061. A locking tongue strip 208 matching with it is inserted in each locking tongue hole 2062, and the upper part of the inner end of the locking tongue strip 208 is set to be an inclined surface with a guiding function, so that the pins in the plug can first contact with the upper inclined surface of the locking tongue strip 208 when extending into the pin hole 2061, and then the locking tongue strip 208 is pushed outward along the locking tongue hole 2062 under the extrusion effect. In addition, in order to avoid leakage accidents, the locking tongue strip 208 is made of insulating material.

[0040] A plurality of telescopic receiving grooves 209 are provided on the back of the insulating panel 201 outside each circular groove 203, and the specific number of the telescopic receiving grooves 209 is determined by the specific type of the pin hole 2061 on the insulating swivel 206. When the pin hole 2061 is a two-pin perforation, two telescopic receiving grooves 209 are provided, and when it is a three-pin perforation, three telescopic receiving grooves 209 are provided. A channel radially connected to the circular groove 203 is provided at the side end of the telescopic receiving groove 209 close to the circular groove 203, and a T-shaped locking block 210 is provided in each telescopic receiving groove 209, and one end of the locking block 210 is extended through the channel to the circular groove 203, and then a spring 211 is provided in the telescopic receiving groove 209 to support the locking block 210 toward the circular groove 203.

[0041] When the wall socket disclosed in the second embodiment is not in use, the pin hole 2061 on the insulating swivel 206 and the plug socket 102 on the socket body 100 are rotated and misaligned with each other due to the force of the torsion spring 207, and at this time, the lock tongue hole 2062 on the insulating swivel 206 is aligned with the channel on the telescopic receiving groove 209, and the locking block 210 is pushed toward the center of the insulating swivel 206 under the force of the spring 211, so that the end of the locking block 210 extends into the lock tongue hole 2062 and pushes the inner end of the lock tongue strip 208 into the pin hole 2061 (see attached Fig. 9 ). In this locked state, the entire insulating rotator 206 cannot rotate in the circular groove 203 due to the circumferential limiting effect of the locking block 210 .

[0042] When the wall socket is in use, the user inserts the pins in the plug into each hole of the corresponding pin hole 2061 at the same time. Under the pressure of the pins, the lock tongue strip 208 is pushed toward the telescopic storage groove 209 until the pins are fully extended to the lower end of the pin hole 2061. At this time, the abutment between the inner end of the locking block 210 and the outer end of the lock tongue strip 208 is located in the annular gap between the insulating swivel 206 and the circular groove 203 (see attached Figure 8 ), and then rotating the insulating swivel 206 will not be restricted. When the pins on the plug are aligned with the plug jacks 102 on the socket body 100, the plug can be inserted into the socket body 100 and connected to the circuit by pressing it hard. Example 3

[0043] Example 3 discloses a wall socket that is further improved based on Example 1 or Example 2, and the similarities between it and Example 1 or Example 2 will not be described again.

[0044] Reference Figure 1 , Attachment Figure 2 and attached Figure 3 In the third embodiment, a protective cover 300 is connected to the upper end of the socket body 100 by rotation, and the lower end of the protective cover 300 is open, so as to facilitate the wiring harness to be led out from the opening at the lower end.

[0045] A plug-in card block 301 is fixedly disposed on the top surface of the protective cover 300 , and an elastic card strip 302 is fixedly disposed at a corresponding position on the upper surface of the socket body 100 . The elastic card strip 302 is normally designed in a U shape, and its two ends are made of elastic plastic.

[0046] When the wall socket disclosed in this embodiment 3 is not in use, the protective cover 300 can be directly flipped downward to cover the entire socket body 100 and the safety protection device 200; when the plug needs to be inserted into the socket body 100, the protective cover 300 is flipped upward by 90°, so that the plug-in card block 301 is inserted into the elastic card strip 302 and fixed, thereby facilitating subsequent operations. After the plug is inserted, the protective cover 300 can be directly flipped downward with force to cover the socket body 100, the safety protection device 200 and the plug, so that it has a certain dustproof and waterproof effect.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
