[0002] A standard European electrical outlet typically features a safety flap outside its sockets that opens and closes by turning. A torsion spring is located on the back of this flap, which returns it to the closed position to prevent the ingress of foreign objects. When in use, the flap must be manually turned to release the socket. However, this flap is enclosed within the outlet housing. Therefore, when inserting a plug, it is often difficult for the user to access the flap and engage it with the plug's prongs to turn it. This impairs the ease of use and smooth operation of the outlet. Content of the invention

Specific embodiments

[0013] The technical solutions in the embodiments of the invention are described below in conjunction with the accompanying drawings, and it is clear that the described embodiments represent only a portion of the embodiments of the invention and not all embodiments. Based on the embodiments in the invention, all other embodiments that a person skilled in the art could achieve without inventive activity fall within the scope of protection of the invention.

[0014] To achieve the above objective, the present invention provides the following technical solution: a protective cap for a European socket, as in Fig. 1 to 4 shown, which includes the following: a rotary flap 1, wherein several first through holes 101 are provided in the upper part of the rotary flap 1, which serve to allow a plug to penetrate the rotary flap 1; several sliding blocks 2, each of which is firmly connected to the upper part of the rotary flap 1, the sliding blocks 2 serving to rotate the rotary flap 1; a base 3 which is arranged on the bottom of the rotary flap 1, wherein a rotary component 5 for rotating the rotary flap 1 is provided at the connection point between the rotary flap 1 and the base 3, wherein several second through-holes 301 are provided on the upper part of the base 3, which serve to allow a plug to penetrate the base 3; a top cover 4, which is arranged on the upper part of the rotary flap 1, wherein a limiting component 6 is provided at the connection point between the rotary flap 1 and the top cover 4, wherein several third through holes 401 are provided in the upper part of the top cover 4, wherein the sliding blocks 2 extend through the third through holes 401 and the third through holes 401 serve to allow a plug to penetrate the top cover 4, and wherein several markings 402 are provided on the upper part of the top cover 4, which serve to indicate the direction of rotation of the rotary flap 1.

[0015] It should be noted that the designated base 3, the rotating flap 1, and the top cover 4 are each formed as a single piece. Compared to the conventional design, where the base 3 is divided into two parts, this simplifies the installation of the protective cap. The rotating flap 1, the base 3, and the top cover 4 each have holes that intersect during use. To install the protective cap, a bolt is inserted directly through the holes in the rotating flap 1, the base 3, and the top cover 4, and the protective cap is then secured in the desired position using the bolt. The formed first through-holes 101 and second through-holes 301 are designed with dimensions that correspond to the pins of a standard plug. This ensures smooth insertion of the plug and a connection with the electrically conductive elements within the socket.The third set of through-holes 401 are curved so that the plug pins can still pass through the top cover 4 even if the first set of through-holes 101 have shifted due to rotation. In everyday use, the first set of through-holes 101 and the second set of through-holes 301 are offset from each other, preventing objects from being inserted directly through the protective cover. This protects both the socket and the user, preventing the user from accidentally inserting other objects into the socket and receiving an electric shock. A number of sliding blocks 2 are also permanently attached to the top of the rotating cover 1. During use, the plug pins move to the side of the sliding blocks 2, causing the pins to engage the sliding blocks 2 and the rotating cover 1 simultaneously.This design solves the problem that the rotary flap 1 is difficult to turn due to the lack of points of attack on the plug pins, thus ensuring smooth operation.

[0016] Specifically, the rotary component 5 comprises a mounting ring 502 fixedly connected to the upper part of the base 3, wherein a torsion spring 504 is arranged within the mounting ring 502, wherein a first through-hole 501 is provided on one side of the mounting ring 502 and a second through-hole 503 is provided on the other side of the mounting ring 502. The two ends of the torsion spring 504 each extend through the first through-hole 501 and the second through-hole 503, respectively. A first insertion groove 505 is formed on one side of the lower part of the rotary flap 1 and a second insertion groove 506 is formed on the other side of the lower part of the rotary flap 1, wherein the two ends of the torsion spring 504 each engage in the first insertion groove 505 and the second insertion groove 506, respectively.

[0017] It should be noted that the mounting ring 502 is manufactured integrally with the base 3. During assembly, the torsion spring 504 is inserted into the mounting ring 502. To receive and secure the torsion spring 504, the first through-hole 501 and the second through-hole 503 are provided on both sides of the ring body of the mounting ring 502. One end of the spring is blocked by the second through-hole 503 and therefore cannot move, while the other end is designed by the arc-shaped first through-hole 501 in such a way that movement of the other end of the torsion spring 504 is permitted. Accordingly, a fixing structure is also provided on the lower part of the rotary flap 1, which interacts with both ends of the torsion spring 504.More precisely, a first insertion groove 505 is provided on one side of the lower part of the rotary flap 1, and a second insertion groove 506 on the other side, with these two insertion grooves each corresponding to the two through-holes. When the other end of the torsion spring 504 engages in the first insertion groove 505, one end moves together with the rotary flap 1. One end of the torsion spring 504 engages in the second insertion groove 506. Thus, when the rotary flap 1 carries the other end of the torsion spring 504 along with it, one end of the torsion spring 504 cannot rotate due to the limitation imposed by the second through-hole 503.

[0018] Furthermore, when the user drives the rotary flap 1 to rotate, the torsion spring 504 is forced to twist, thereby storing elastic potential energy; when the user removes the external force, the torsion spring 504 releases the stored energy and drives the rotary flap 1 to automatically return to its original equilibrium position.

[0019] Specifically, the limiting component 6 comprises a limiting block 602 fixedly connected to one side of the rotary flap 1, and a limiting groove 601 is provided on the upper part of the base 3, with the limiting block 602 engaging in the limiting groove 601.

[0020] It should be noted that the formed limiting groove 601 corresponds to the provided limiting block 602, allowing the limiting block 602 to move within the limiting groove 601. When the limiting block 602 moves until it contacts the inner walls on both sides of the limiting groove 601, it is blocked by the limiting groove 601 and can no longer move. In this way, the movement of the limiting block 602 is limited, which in turn restricts the rotation angle of the rotary flap 1, which is rigidly connected to the limiting block 602.

[0021] Finally, it should be noted that the embodiments described above are merely preferred examples of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art may further modify the technical solutions described in the respective aforementioned embodiments or replace some of the technical features contained therein with equivalent features. All modifications, equivalent replacements, improvements, and the like made in the spirit and within the framework of the principles of the present invention fall within the scope of protection of the present invention.
