Description

Technical Field

[0001] This utility model belongs to the field of AC socket technology, and specifically relates to an AC socket with a flip cover. Background Technology

[0002] An AC socket is an electrical device used to connect to alternating current (AC) power. It is typically installed on walls, socket panels, or electrical appliances to provide a power access point for various appliances. AC sockets have specific socket shapes and specifications to accommodate different types of plugs. Common AC sockets are divided into two-prong and three-prong types. Three-prong sockets usually have a grounding function, which can provide a safer power connection for appliances. The design of AC sockets takes into account factors such as current carrying capacity, insulation performance, and safety. It can withstand a certain range of current loads to ensure that appliances operate normally without overloading. At the same time, good insulation materials and structural design can prevent electric shock accidents. In daily life and industrial fields, AC sockets are widely used in various electrical appliances, such as televisions, computers, refrigerators, washing machines, etc., providing convenient power supply for people's lives and production.

[0003] Chinese patent CN209169478U discloses an AC socket, which includes a plastic base. The front of the plastic base forms a cavity with the back of the plastic base facing the back of the plastic base. A pin is provided in the cavity. The pin includes a long pin and a short pin. The long pin is located at the center of the cavity, and the short pin is symmetrically arranged with respect to the long pin. A mounting platform is formed on the back of the plastic base. Long terminals and short terminals are provided on the mounting platform. The long terminals are located on the center line of the mounting platform, and the short terminals are symmetrically arranged with respect to the long terminals. A bracket is provided on the mounting platform, and the bracket is arranged around the side wall of the mounting platform. Through the layout design of the plastic base, the position of the pin and the layout of the long and short terminals are reasonably designed, and the bracket is provided on the side wall of the mounting platform to ensure the stability of the entire socket.

[0004] While the aforementioned device offers some convenience in practical use, it also exhibits significant shortcomings. The most prominent issue is the lack of effective external protection for the socket. When not in use, the slot is completely exposed to the air. Prolonged exposure to the complex and humid environment makes the socket highly susceptible to damage and corrosion. Over time, the internal components of the AC socket may be damaged by moisture and dust, rendering the socket unusable. Furthermore, the exposed slot poses a significant risk of electrical leakage. Dust, debris, or external impacts that deform the internal structure can compromise the socket's insulation, leading to a leakage accident. This problem is particularly pronounced in older homes or with sockets that have been in use for a long time. A leakage could not only damage connected electrical appliances but also pose a serious threat to the user's life. Therefore, this device has inherent defects and deficiencies that urgently require improvement to enhance its safety and reliability. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an AC socket with a flip cover to solve the problems raised in the background art.

An elastic seat 3 is fixedly connected to the top front end of the socket body 2. A protective cover 4 is fixedly mounted on the outside of the elastic seat 3. The protective cover 4 covers the front of the socket body 2. A limiting mechanism 6 is fixedly mounted on the end of the protective cover 4 away from the elastic seat 3. The protective cover 4 is made of elastic stainless steel.

[0025] The resilient seat 3 includes a concave seat 31, which is fixedly installed on the top front end of the socket body 2. A connecting shaft 32 is rotatably connected to the inner side of the concave seat 31. A hinge frame 33 is rotatably connected to the middle of the outer surface of the connecting shaft 32. The outer end of the hinge frame 33 is fixedly connected to the protective cover 4. Torsion springs 34 are fixedly installed at both ends of the hinge frame 33. The outer ends of the torsion springs 34 are fixedly connected to the inner side of the concave seat 31. The mounting plate 1 provides a stable mounting base for the socket body 2. The resilient seat 3 at the top front end of the socket body 2 fits tightly with the protective cover 4. The protective cover 4 is made of elastic stainless steel, which is sturdy and durable. With a certain degree of elasticity, the concave seat 31 in the elastic seat 3 is connected to the hinge frame 33 through the connecting shaft 32, so that the protective cover 4 can rotate flexibly. The torsion springs 34 at both ends of the hinge frame 33 provide power for the automatic opening and closing of the protective cover 4. When the socket is not in use, the torsion springs 34 reset and drive the protective cover 4 to cover the front of the socket body 2, which plays a good protective role and can prevent dust, moisture and other substances from entering the socket and extend the service life of the socket. At the same time, during use, the plug can be inserted by opening the protective cover 4, which is convenient to operate. This design not only improves the safety of the socket, but also enhances the convenience of use.

[0026] refer to Figure 1-Figure 3Mounting plate 1 has mounting holes 5 at both ends, which are countersunk holes. A sealing gasket 7 is fixedly connected to the side of the protective cover 4 near the socket body 2. The sealing gasket 7 covers the front plug of the socket body 2. The mounting holes 5 at both ends of the mounting plate 1 are countersunk holes, which allow the head of the fixing screw to be recessed into the hole when installing the socket, making the surface of the socket more flat and beautiful after installation. It also avoids the safety hazards such as scratches that may be caused by the screw head protruding. The sealing gasket 7 is fixedly connected to the side of the protective cover 4 near the socket body 2. When the protective cover 4 covers the front plug of the socket body 2, the sealing gasket 7 can fit tightly, effectively preventing dust, moisture and other impurities from entering the socket. It provides good sealing protection for the socket, greatly reducing the risk of socket damage or leakage due to external environmental factors, and further improving the safety and reliability of the socket.

[0027] refer to Figure 1-Figure 4 The limiting mechanism 6 includes a horizontal rail 61, which is fixedly installed on the end of the protective cover 4 away from the elastic seat 3. A lead screw 62 is rotatably connected to the inner side of the horizontal rail 61. The two ends of the lead screw 62 have opposite thread directions and both ends of the lead screw 62 pass through the horizontal rail 61. Sliding blocks 63 are threadedly connected to the two ends of the lead screw 62 inside the horizontal rail 61. The sliding blocks 63 are slidably connected to the inner side of the horizontal rail 61. A clamping arm 64 is fixedly connected to the side of the sliding block 63 away from the horizontal rail 61. An anti-slip component 65 is fixedly connected to the inner side of the clamping arm 64. A clamping groove 66 is formed on the inner side of the anti-slip component 65. The overall cross-sectional shape of the clamping groove 66 is an isosceles trapezoid. Anti-slip protrusions 67 are fixedly connected at equal intervals on both sides of the inclined surface inside the clamping groove 66. Adjusting knobs 68 are fixedly connected to both ends of the lead screw 62 through the horizontal rail 61. Anti-slip stripe grooves are formed at equal intervals on the outer surface of the adjusting knobs 68. The horizontal rail 61 is fixed to the protective cover. 4. One end provides a stable mounting base for the internal components. The lead screw 62 rotates inside the horizontal rail 61. The ingenious design of the opposite thread direction at both ends allows the sliding blocks 63 at both ends to slide synchronously in opposite directions when the lead screw 62 rotates, thereby driving the clamping arm 64 to achieve precise displacement adjustment. The anti-slip part 65 on the inner side of the clamping arm 64 and the clamping groove 66 with an isosceles trapezoidal cross section can better fit the shape of the plug, increase the contact area, and improve the stability of clamping. The anti-slip protrusions 67 on the inclined surfaces on both sides of the clamping groove 66 further enhance the friction between the plug and the plug, effectively preventing the plug from accidentally falling off. The adjustment knobs 68 at both ends of the lead screw 62 are convenient for users to operate. The anti-slip stripe grooves on its outer surface increase the friction during operation, making the adjustment easier and more accurate. This limiting mechanism 6 greatly improves the stability and safety of the socket during use, providing users with reliable power supply protection.

[0028] Operating principle and advantages: By setting the elastic seat 3 and protective cover 4, this device is endowed with excellent performance during use. During the operation of the device, the reset function of the torsion spring 34 can help drive the connecting shaft 32 of the hinge frame 33 inside the concave seat 31 to rotate. When the hinge frame 33 rotates, it can drive the protective cover 4 to rotate accordingly, thereby causing the protective cover 4 to tightly cover the front of the socket body 2. When the socket body 2 needs to be used, it can be opened by adjusting the rotation of the protective cover 4. At this time, the torsion spring 34 is pressed and in a compressed state. Then, the plug is inserted into the inside of the socket body 2 to complete the power connection. During use, when the plug is pulled out, the torsion spring 34 will automatically reset, thereby driving the protective cover 4 to close the front of the socket body 2. At the same time, the sealing gasket 7 can play an auxiliary sealing role. It can be seen that this device can exhibit excellent sealing and protection performance during the overall use. This design can not only extend the service life of the socket body 2, but also effectively prevent the socket body 2 from leaking electricity, providing users with a safer and more reliable power environment.

[0029] By incorporating a limiting mechanism 6, this device exhibits numerous advantages during use. When the protective cover 4 is closed on the front of the socket body 2, the limiting mechanism 6 is cleverly concealed at the bottom of the socket body 2, without affecting the overall aesthetics of the device. When the plug is inserted into the socket body 2, the adjusting knob 68 can be turned, thereby driving the lead screw 62 to rotate inside the horizontal rail 61. The rotation of the lead screw 62 drives the sliding block 63 to slide inside the horizontal rail 61. Since the threads at both ends of the lead screw 62 rotate in opposite directions, as the lead screw 62 rotates, it synchronously drives the sliding block 63 to slide at both ends inside the horizontal rail 61. When the sliding block 63 slides, it will cause the clamping arms 64 to move relative to each other. When the plug is inserted into the socket body 2 and the protective cover 4 of the socket body 2 is opened, the relative displacement of the clamping arms 64 can be adjusted so that the anti-slip part 65 on the inner side of the clamping arm 64 can fit and clamp the plug to the outer side. At this time, the anti-slip protrusion 67 inside the clamping groove 66 can fit firmly against the outer surface of the plug. This design allows the device to clamp the plug more securely, ensuring that the plug can be stably inserted into the socket body 2, effectively avoiding the situation of the plug accidentally falling off, and greatly improving the overall stability of the device during use.
