Description

Technical Field

[0001] This utility model belongs to the field of socket technology, and specifically relates to a child-proof socket. Background Technology

[0002] In modern life, the widespread use of various electrical appliances has made sockets an indispensable basic electrical facility in homes, schools, offices, and other environments. As children's activity range in daily life continues to expand, cases of children inserting foreign objects such as fingers, keys, and hairpins into socket holes out of curiosity are not uncommon, seriously threatening children's lives and family happiness. Therefore, the child-proof insertion function of sockets has become an important part of ensuring electrical safety.

[0003] Currently, most sockets on the market are equipped with some child-proof structures, the most common being the use of elastic shields. This design is based on the fact that children's fingers are relatively weak. The elastic shields physically block the sockets. When a child tries to insert their finger, the force applied is insufficient to overcome the elastic resistance of the shields, and the socket cannot be opened. This reduces the risk of accidental electric shock to a certain extent. This basic protective structure can play a certain protective role in dealing with children's unintentional simple touching behavior.

[0004] However, the child-proof features of existing sockets still have significant shortcomings in practical applications. When children forcefully insert screwdrivers, nails, or other hard tools into the socket holes, the drawbacks of the existing elastic shielding structure become apparent. Since the elastic shielding is not designed to withstand high-intensity external forces, it can be stretched beyond its elastic limit when subjected to significant pressure from hard tools. Once stretched open, the live parts inside the socket will be directly exposed. If a child inserts a conductive material such as iron, the power can be instantly switched on, leading to an electric shock. Furthermore, the elastic shielding, subjected to prolonged strong pressure, can deform and lose elasticity, further reducing the socket's protective performance during subsequent use. Even minor, normal touches from children may fail to provide protection due to the shielding losing its elasticity. Therefore, the existing technology has poor overall protective capabilities during application and requires redesign. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a child-proof plug socket to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0010] Furthermore, the two oblique insertion holes on the lower end of the socket front cover are arranged in an outward V-shape, and the three straight insertion holes are arranged in a linear pattern.

[0011] Furthermore, both ends of the guide rail are convex in shape, and both ends of the movable sealing block are also convex in shape.

[0012] Furthermore, the movable sealing block is configured as an insulating sealing block, and the movable sealing block is located on the rear side of the positive insertion hole and the oblique insertion hole.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Please refer to Figure 1-4This embodiment of a child-proof socket includes a socket body 1, a socket front cover 2 fixedly installed on the front of the socket body 1, a sealing mechanism 3 provided inside the socket front cover 2, a safety mechanism 6 fixedly connected to one side inside the socket front cover 2, and straight insertion holes 4 evenly spaced at the upper end of the front of the socket front cover 2, and oblique insertion holes 5 on both sides of the lower end of the front of the socket front cover 2.

[0026] The blocking mechanism 3 includes a guide rail 31 and a fixing seat 32. The guide rail 31 is fixedly installed inside the socket front cover 2, and the fixing seat 32 is fixedly connected to the middle of one side of the socket front cover 2. A drive motor 33 is fixedly connected to the outside of the fixing seat 32. The output end of the drive motor 33 passes through the socket front cover 2 and the guide rail 31 and is fixedly installed with a blocking assembly 34. The blocking assembly 34 is movably installed inside the guide rail 31. During the application of this device, the socket front cover 2 on the front of the socket body 1 integrates the core protection components, in which the blocking mechanism 3 and the safety mechanism 6 work together. When idle, the drive motor 33 is in a stationary state, and the movable blocking block 342, which is connected to the two ends of the lead screw 341 by reverse threads, remains closed inside the guide rail 31, tightly covering the positive insertion hole 4 and the oblique insertion hole 4. The socket 5 forms a physical protective barrier to prevent children from inserting their fingers or foreign objects. When the socket needs to be used, after authorization by the security mechanism 6 (such as fingerprint recognition module verification), the control module sends a start signal to the drive motor 33. The drive motor 33 drives the lead screw 341 to rotate. Utilizing the opposite thread directions at both ends of the lead screw 341, the two movable sealing blocks 342 slide synchronously in opposite directions along the guide rail 31 to open, exposing the socket for easy plug insertion. After use, the drive motor 33 runs again, driving the movable sealing blocks 342 to move synchronously in opposite directions to re-close the socket. The convex-shaped design of the guide rail 31 and the movable sealing blocks 342 ensures the stability and accuracy of the sealing blocks during sliding, ensuring reliable operation of the protective function.

[0027] Please refer to Figures 3-4The sealing assembly 34 includes a lead screw 341, which is rotatably connected to the inside of the guide rail 31. The two ends of the lead screw 341 have opposite thread directions, and both ends of the lead screw 341 are threadedly connected to movable sealing blocks 342. The movable sealing blocks 342 are slidably connected to the two ends of the inside of the guide rail 31. The oblique insertion holes 5 on both sides of the lower end of the socket front cover 2 are arranged in an outward V-shape, and the three straight insertion holes 4 are arranged linearly. Both ends of the inside of the guide rail 31 are convex. Both ends of the movable sealing blocks 342 are also convex. The movable sealing blocks 342 are insulating sealing blocks and are located on the rear side of the straight insertion holes 4 and oblique insertion holes 5. During the application of this device, when the driving electric current... When the motor 33 starts, the lead screw 341 rotates within the guide rail 31. Utilizing the opposite screw directions at both ends, the movable sealing block 342 slides synchronously in the opposite direction along the guide rail 31. On the socket front cover 2, the three linearly arranged positive sockets 4 and the outward-facing oblique sockets 5 are all covered by the rear insulating sealing block. When needed, the movable sealing block 342 smoothly opens under the limit of the convex guide rail 31, exposing the socket. After use, the drive motor 33 reverses the drive, and the sealing block closes again, forming a physical barrier. The convex structure ensures sliding stability, the insulating material eliminates the risk of leakage, and the outward-facing design of the oblique socket 5 is compatible with triangular plugs, achieving a balance between safety and ease of use.

[0028] Please refer to Figures 1-4The safety mechanism 6 includes an inner box 61, which is fixedly connected to one side of the socket front cover 2. The inner box 61 houses a control module and a fingerprint recognition module. A fingerprint reader 62 is fixedly connected to the front of the inner box 61, and is electrically connected to both the control module and the fingerprint recognition module. A circular groove 7 is formed in the middle of one side of the socket body 1, and a power switch 8 is fixedly connected inside the groove 7. The power switch 8 is electrically connected to the socket body 1. During the application of this device, the safety mechanism 6 and the power switch 8 together form a comprehensive security protection system. When the user uses the socket, they need to press their finger on the fingerprint reader 62 on the front of the inner box 61. The fingerprint reader 62 quickly collects fingerprint information and transmits it to the fingerprint reader inside the inner box 61. The fingerprint recognition module analyzes the collected fingerprint features using a complex algorithm and compares them with pre-recorded fingerprint data. If the comparison is successful, the fingerprint recognition module sends a matching signal to the control module. Upon receiving the signal, the control module sends a start command to the drive motor 33. The drive motor 33 rotates and opens the sealing mechanism 3, exposing the socket for user use. If the fingerprint comparison fails, the control module will not issue a command, and the sealing mechanism 3 remains closed, preventing children or unauthorized personnel from using the socket. In addition, the power switch 8 in the circular groove 7 on the side of the socket body 1 can manually control the power supply of the entire socket. When the socket is not used for a long time, the user can turn off the power by flipping the power switch 8, completely eliminating the potential risk of leakage and further improving the safety factor of electricity use.

[0029] Operating principle and advantages: This child-proof plug socket, through the sealing mechanism 3, provides excellent protection. It uses a combination of a lead screw 341 and a movable sealing block 342. Utilizing the opposite thread directions at both ends of the lead screw 341, the two movable sealing blocks 342 can move synchronously in opposite directions when the drive motor 33 is running. When the socket is not in use, the movable sealing blocks 342 can completely cover the positive socket 4 and the angled socket 5, forming a physical barrier to effectively prevent children's fingers and foreign objects from being inserted. During normal use, the drive motor 33 drives the sealing blocks to open, facilitating plug insertion. The convex design of the guide rail 31 and the movable sealing block 342 not only enhances the stability of the sealing block's sliding but also prevents the sealing block from accidentally falling off or shifting. Furthermore, the choice of insulating material for the sealing block eliminates the risk of leakage at the source. Compared to traditional elastic shields, this structure can withstand greater external impacts, preventing protection failure due to children forcefully inserting their devices.

[0030] During the application of this device, in terms of intelligent protection, the safety mechanism 6 adds another layer of protection to the socket safety. The control module and fingerprint recognition module built into the inner box 61, together with the fingerprint reader 62 on the front, form an intelligent access control system. Only when an adult with a pre-registered fingerprint operates the socket can the blockage be removed and the power be turned on. Even if a child uses tools, they cannot break through this protection mechanism. In addition, the power switch 8 on the side of the socket body 1 supports manual control of the socket's power on and off status. When the socket is not frequently used, the power can be completely cut off, further reducing safety hazards. This design, which combines mechanical protection and intelligent recognition, comprehensively covers the electrical safety risks that children may cause, providing reliable protection for electrical safety in homes and public places.

The movable sealing block 342 is made of PA66-GF30 reinforced nylon, with a thickness of 2-3mm, a width of 20-25mm, and a height of 10-15mm. The guide rail 31 is made of PC+ABS alloy, with an internal convex groove width of 6-8mm and a depth of 3-4mm. The diameter of the straight insertion hole 4 is 6.5-7mm, the diameter of the angled insertion hole 5 is 6-6.5mm, and the included angle between the two angled insertion holes 5 is 30°-45°. Regarding electronic components, the drive motor 33 is a 5V stepper motor of model 28BYJ-48, the fingerprint reader 62 is an AS608 model, and the control module is an STM32F103C8T6 microcontroller. This controller is installed inside the inner casing 61 and connects to the PCB board via a 40-pin dual-row socket. Its power supply is AC220V converted to DC5V by a 12V / 1A switching power adapter. One path directly powers the drive motor 33, and the other path is converted to 3.3V via an AMS1117-3.3V voltage regulator chip to power the control module and the fingerprint reader module. All electronic components are connected via 0.5mm... 2 The control module's I / O ports are connected to the signal terminals of each module via pull-up resistors, forming a complete control loop.
