Description

Technical Field

[0001] The present invention relates to a socket structure, and more particularly to an anti-misoperation socket. Background Art

[0002] Most traditional socket switches are designed with a single button. Children may accidentally turn on the power due to curiosity pressing, posing serious safety hazards. Existing technologies such as safety doors and rotary switches only solve the problem of accidental contact with the socket holes, but do not effectively protect the power switch. In addition, although the safety door solves the problem of electric shock in the socket holes, due to the uneven quality of the safety doors, it may be more laborious in actual use, causing inconvenience. Therefore, a batch of solutions for protecting the power plug holes through mechanical structures have emerged, reducing the possibility of correct opening by young children. However, for adult users, the repeated operation steps may be too cumbersome, resulting in negligence in the reset operation after finishing using the socket due to impatience. Summary of the Invention

Detailed implementation

[0016] The present invention will be further explained below with reference to the accompanying drawings.

[0017] As Figure 1 shown, an anti-mis-touch socket strip includes a socket body 1, a protective shell 2, and a double-action unlocking mechanism 3. A plurality of socket holes 11 are provided on the upper surface of the socket body 1; a power-on hole 13 is provided at one end of the socket body 1 for the cable 10 to penetrate and be electrically connected to each socket hole 11. Spring installation positions are provided on both sides of the socket body 1, and the protective shell 2 is installed on both sides of the socket body 1 through reset springs. An installation cavity 12 is provided on the upper surface of the socket body 1 near one end of the cable 10. The double-action unlocking mechanism 3 includes a cover 31, a sliding reset button, a power self-locking reset button, and a limiting mechanism, and is installed in the installation cavity 12 through structures such as reset springs.

[0018] As Figure 2 shown, the protective shell 2 includes a left protective shell 21 and a right protective shell 22. The left protective shell 21 is a box structure with one side open, and a spring installation position 211 opposite to the inner side of the open side is provided on the inner side surface opposite to the open side. The left protective shell 21 is connected to the socket body 1 through a first reset spring group 23. The upper left and right four walls of the left protective shell 21 serve as sliding surfaces and slide along the surface of the socket body 1. The two protective shells can move relative to each other to open and close the socket holes 11. An arc-shaped notch 212 is provided on the side edge of the left protective shell 21 to prevent the protective shell from not being fully reset and closed due to the cable 10. The structure of the right protective shell 22 is the same as that of the left protective shell 21, and the right protective shell 22 is connected to the socket body 1 through a second reset spring group 24.

[0019] As Figure 3As shown in the figure, the installation cavity 12 includes a slider chute 121, a guiding chute 122, a reset chute 123, and a limiting chute. The slider chute 121 is located at the top of the installation cavity 12 and is used for installing the slider 33. The guiding chute 122 is opened on the left bottom surface of the slider chute 121, and the reset chute 123 is opened on the middle bottom surface of the slider chute 121. The reset chute 123 communicates with one end of the guiding chute 122. A hole 126 is opened on the wall surface at the other end (left end) of the guiding chute 122; a reset spring installation position is provided at the bottom of the reset chute 123. The limiting chute is located on the side of the slider chute 121 and includes a first limiting chute 125 and a second limiting chute 124. First clamping blocks 1251 and second clamping blocks 1241 are respectively provided at the front ends of the first limiting chute 125 and the second limiting chute 124.

[0020] As Figure 4 shown in the figure, the sliding and reset button includes a sliding button 32, a slider 33, and a slider reset spring 40. The slider 33 is installed on the slider chute 121. The sliding button 32 is connected to the slider 33, and the two move together along the length direction of the slider chute 121, that is, they can slide from one side to the other side. One end of the slider reset spring 40 is installed in the hole 126 on the side wall at one end of the guiding chute 122, and the other end is connected to the slider 33.

[0021] As Figure 4 , Figure 5 , Figure 9 shown in the figure, the cooperation between the slider 33, the sliding button 32, and the slider reset spring 40 is specifically as follows: a sliding button notch 331 is opened on the middle line of the left side of the slider 33, a limiting concave platform 332 is provided at the inner bottom of the sliding button notch 331, a base 321 protruding outward is provided at the bottom of the sliding button 32, the main body of the sliding button 32 is embedded into the sliding button notch 331 from the bottom upward, and the limiting concave platform 332 controls the vertical degree of freedom of the sliding button 32 by restricting the base 321 to prevent it from falling off under the action of the vertical reset spring 37. A guiding block 333 is provided at the bottom left of the slider 33. The guiding block 333 is placed in the guiding chute 122 and is connected to one end of the slider reset spring 40. Among them, the width of the sliding button 32 is greater than the width of the guiding chute 122. After the sliding button 32 is embedded into the sliding button notch 331 from the bottom upward, its bottom surface is flush with the bottom surface of the slider 33.

[0022] The power self-locking reset button includes a power button 36, a vertical reset spring 37, and a self-locking structure. One end of the vertical reset spring 37 is installed in the reset spring installation position at the bottom of the reset chute 123, and the other end is connected to the bottom surface of the power button 36. When the vertical reset spring 37 is in a relaxed state, the top surface of the power button 36 is flush with the bottom surface of the slider chute 121. The self-locking mechanism adopts a ratchet motion mechanism or a clamping groove mechanism in a traditional socket to make the power button 36 a self-locking button.

[0023] AsFigure 7 , Figure 10 As shown in the figure, the limiting mechanism includes a first limiting block 34, a second limiting block 38, a first limiting block spring 35, and a second limiting block spring 39. As Figure 6 shown, the main body of the first limiting block 34 is a trapezoidal block. The top of the trapezoidal block is an inclined surface 344. The bottom of the trapezoidal block is provided with a first limiting block base 341, and a first limiting block spring installation position is provided on the bottom surface of the first limiting block base 341. A push block 342 is provided on one side surface of the trapezoidal block. The first limiting block 34 is installed in the first limiting chute 125, and the inclined surface 344 faces left. One end of the first limiting block spring 35 is connected to the first limiting block base 341, and the other end is connected to the bottom of the first limiting chute 125. The first locking block 1251 in the first limiting chute 125 restricts the first limiting block base 341, so that the first limiting block 34 can only move in the first limiting chute 125. The only difference in structure from the first limiting block 34 is that the second limiting block 38 is not provided with a push block 342. The second limiting block 38 is installed in the second limiting chute 124, and the installation method is the same as that of the first limiting block 34.

[0024] As Figure 8 shown, the contour of the cover 31 is the same as the top view contour of the installation cavity 12, and is used to encapsulate the double-action unlocking mechanism 3 after installation. A sliding button chute 311 is provided on the main trunk of the cover 31, and the sliding button 32 can move in the sliding button chute 311 when moving. A push block chute 312 is provided at the position where the cover 31 covers the first limiting chute 125. The push block 342 can move along the push block chute 312, and the first limiting block 34 is driven by the push block 342 to retract into the first limiting chute 125, releasing the locking of the slider 33.

[0025] Specific operation process: As Figure 4 , Figure 7 , Figure 9 , Figure 10 shown, they are respectively the states of the sliding reset button and the limiting mechanism when the present invention moves from the initial position to the termination position. When the user uses the present invention, first open the protective shell 2, insert the plug into the socket hole 11, and after releasing the protective shell 2, due to the obstruction of the plug, the protective shell 2 cannot be reset.

[0026] At this time, the sliding reset button is still in the initial position. Under the extrusion of the slider 33, the first limiting block 34 retracts into the first limiting chute 125, and the first limiting block spring 35 is in a state of storing energy; the second limiting block 38 extends out of the second limiting chute 124, with the inclined surface facing left, restricting the right displacement of the slider 33 to prevent loosening.

[0027] Push the sliding button 32 to drive the slider 33 to move on the slider slot 121. When the sliding button 32 is aligned with the power button 36, press the sliding button 32 to drive the power button 36 to press down and turn on the power. Under the action of the traditional reset mechanism, the power button is self-locked and reset, and the sliding button 32 is pushed back to the upper position. During the movement, the slider 33 squeezes the inclined surface of the second limit block 38, so that the second limit block 38 retracts into the second limit slot 124. The first limit block 34, due to the loss of the squeezing force of the slider 33, extends under the action of the first limit block spring 35, and prevents the slider 33 from resetting through the back of the inclined surface of the first limit block 34, so that the power unlocking method is converted from the "slide + press" double action mechanical unlocking to the single action of pressing to turn on or off the power. In daily use at home, users do not need to repeat the "slide + press" double action mechanical unlocking method, which improves the user experience.

[0028] When not in use, the push block 342 only needs to be moved along the push block slot 312 to pull the first limit block 34 into the first limit slot 125, thereby releasing the restriction on the slider 33. The slider 33 is reset under the action of the slider reset spring 34, thereby switching the single action of pressing to turn on or off the power supply to the double action mechanical unlocking of "slide + press". Then unplug the plug to release the restriction on the protective shell 2. The protective shell 2 is quickly reset under the action of the reset springs 23 and 24, closing the switch and the socket port together, realizing one-button reset and protection. It is difficult for children to open the protective shell 2 and then perform double action unlocking by themselves.

[0029] The present invention adopts a "slide + press" dual-action mechanical unlocking switch design and a protective shell design to protect the power switch and the power plug at the same time. It does not require external tools and increases the complexity of operation through a purely mechanical structure, thereby reducing the possibility of children accidentally touching the power plug. At the same time, during use, the dual-action switch must be turned on with the protective shell turned on, further reducing the possibility of children touching the live socket by operating alone. Both the dual-action switch and the protective shell have reset capabilities and do not require frequent operation. At the same time, the design of the limit mechanism enables the present invention to have the ability to convert between the dual-action switch and the single-action switch, further enhancing the convenience of the use process.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
