Description

Technical Field

[0001] The present invention relates to the technical field of electrical sockets, and in particular to a floating block self-locking child safety socket. Background Art

[0002] A socket, also known as a power outlet or a switch socket, is a receptacle that accepts one or more circuit wiring. Various wires can be inserted into it, making it easy to connect to other circuits. The connection and disconnection between the wires and the copper components ultimately connect and disconnect that circuit. To prevent children from touching the socket and getting an electric shock, sockets with power switches have emerged. However, existing sockets only provide protection when not in use. Pulling out a small section of the plug while the socket is in use, exposing the metal piece, can also cause electric shock, posing a safety threat.

[0003] Authorization announcement No. CN217522274U proposes a safety socket; it includes a base, a socket shell, an unlocking button, a floating block, a self-locking mechanism, and a socket. The base is snap-fitted to the socket shell, and the unlocking button and the floating block are connected in sequence on the outer surface of the socket shell. The floating block is provided with a socket, and the unlocking button and the floating block are connected through a self-locking mechanism; the self-locking mechanism includes a lever and a tilted top block. The middle opening of the lever is rotatably connected to the base. The end away from the unlocking button is square and the other end is a rectangular hole structure. The square is chamfered at a right angle near the upper edge of the floating block to form an inclined surface. The invention uses a self-locking mechanism to make the plug self-locking and energized when inserted, and automatically cut off the power once it is pulled out, which greatly improves the safety performance of the socket and has a simple structure and is easy to use. The safety socket of this structure relies on the self-locking and unlocking of the self-locking mechanism to change the distance between the plug and the clamping part of the live copper sheet to achieve safe power on and off. Even if the distance between the socket and the clamping part of the live copper sheet is large when the float block is floated out, when children play, they force long conductive objects into the socket. The long conductive objects can be directly connected to the live part, and if they touch the live wire, there will still be a risk of electric shock. Summary of the Invention

[0004] The purpose of the present invention is to provide a floating block self-locking child safety socket, which blocks the socket through a self-locking mechanism to prevent accidental touch, and then controls the connection and disconnection of the socket and the copper sheet clamping part through an on-off mechanism to improve safety performance.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a floating block self-locking child safety socket, comprising a base, a shell, an unlocking button, a floating block, a self-locking mechanism and an on-off mechanism, the base is snap-fitted to the shell, the unlocking button and the floating block are floatingly connected to the shell, the floating block is also provided with a socket, the floating block comprises a shell, a pin seat slidably connected to the shell, the on-off mechanism is slidably connected to the top surface of the pin seat, and a copper sheet clamping portion is also provided on the bottom surface.

[0006] The self-locking mechanism includes a lever assembly and a limit assembly, the lever assembly is arranged in the shell, the limit assembly is arranged on the pin seat, the lever assembly consists of a rocker arm and a fulcrum, wherein one end of the rocker arm is rotatably connected to the unlocking button and the other end is rotatably connected to the floating block, the fulcrum is fixed on the shell and hinged to the middle part of the rocker arm, the limit assembly consists of a shift rod and a spring, wherein the shift rod is slidably connected to the pin seat, one end of the shift rod is connected to the pin seat through a spring, and the other end extends out of the pin seat.

[0007] The on-off mechanism includes a connecting plate, a paddle, a contact and a spring. A cylindrical protrusion is provided on one side of the connecting plate and a slope is provided on the other side. One end of the spring is connected to the pin seat and the other end is connected to the cylindrical protrusion. The paddle is vertically connected to the connecting plate, and the lower end of the paddle is rotatably connected to the copper sheet clamping portion. The contact is provided on the paddle on the same side as the spring.

[0008] The two ends of the shifting rod are cylindrical structures, and an inclined block is arranged at intervals in the middle. The inclined block is provided with an inclined surface on a surface close to the shell.

[0009] The paddle is a bent structure, the bent inclined surface is in the same direction as the inclined surface on the connecting plate, and the maximum bending point is located at the lowest end of the socket.

[0010] A set of opposite levers is provided on the socket, and the socket is completely blocked by the levers.

[0011] The beneficial effects of the present invention are: 1) a limit assembly is provided on the plug seat, and the socket is blocked by the lever therein to prevent children from accidentally touching it while playing. At the same time, the extension part at one end of the lever will block the shell in the float from sliding downward and connecting with the plug seat under the action of the spring, so that the plug cannot contact the socket of the plug seat during use, and there is no risk of electric shock when inserting it.

[0012] 2) The plug seat is also equipped with an on-off mechanism. When in use, the plug needs to first contact the connecting plate to displace it, and then continue to insert and displace the paddle to rotate the contact to connect with the live contact. Simply forcibly inserting a conductive object into the plug seat will not push the connecting plate to move to the live contact to energize it, which can effectively avoid the risk of electric shock.

DETAILED DESCRIPTION

[0021] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0022] Example: Figures 1 to 7 As shown, a floating block self-locking child safety socket according to the present invention includes a base 1, a shell 2, an unlocking button 3, a floating block 4, a self-locking mechanism 5 and an on-off mechanism 6. The base 1 is snap-fitted with the shell 2, the unlocking button 3 and the floating block 4 are floatingly connected to the shell 2, and the floating block 4 is further provided with a socket 7. The floating block 4 includes a shell 8, a latch seat 9 slidably connected to the shell 8, the on-off mechanism 6 is slidably connected to the top surface of the latch seat 9, and a copper sheet clamping portion 10 is fixed to the bottom surface. The self-locking mechanism 5 includes a lever assembly 51 and a limit assembly 52. ​​The lever assembly 51 is arranged in the shell 8, and the limit assembly 52 is arranged on the latch seat 9. The lever assembly 51 is composed of a rocker 511 and a fulcrum 512. One end of the rocker arm 511 is rotationally connected to the unlocking button 3, and the other end is rotationally connected to the floating block 4. The fulcrum 512 is fixed on the shell 2 and hinged to the middle part of the rocker arm 511. Specifically, slots are provided on both ends of the rocker arm 511, one end is hinged to the connecting parts on both sides of the unlocking button 3, and the other end is hinged to the connecting part on the lower end of the shell 8. The middle fulcrum 512 is fixed on the inner wall of the shell 2, so that a lever mechanism is formed between the shell 8 of the floating block 4 and the unlocking button 3 through the rocker arm 511, that is, when the shell 8 is pressed down, the unlocking button 3 floats, and when the unlocking button 3 is pressed again, the shell 8 floats. When the shell 8 floats, the socket 7 is separated from the pin seat 9, thereby increasing the contact distance and preventing accidental touch, thereby improving safety performance.

[0023] The limiting assembly 52 is composed of a lever 521 and a spring 522, wherein the lever 521 is slidably connected to the pin seat 9, one end of the lever 521 is connected to the pin seat 9 by a spring 522, and the other end extends out of the pin seat 9, and the two ends of the lever 521 are cylindrical structures, with an inclined block 11 arranged at intervals in the middle, and an inclined surface is arranged on the side of the inclined block 11 close to the shell 2, and a group of opposite levers 521 are provided on the socket 7, and the socket 7 is completely blocked by a group of levers 521. When in use, the socket 7 is blocked by two oppositely arranged levers 521, and the socket 7 of the plug is inserted into the socket 7 of the shell 8, and the shell 8 of the float 4 is pressed down first. During the pressing process, the distance between the shell 8 and the pin seat 9 is gradually reduced. When pressed down until the plug contacts the lever 521, it first contacts the inclined surface of the inclined block 11. Figure 5 As shown, one plug portion contacts the levers 521 in two directions at the same time. After being pressed down, the two levers 521 move in different directions, and at the same time compress the spring 522 on the other end. When moving, the extension part at the end of the lever 521 contracts inward. When the outermost end contracts into the shell 8, the shell 8 is not blocked by the extension part and can continue to be pressed down to contact the pin seat 9. At this time, the plug is normally inserted into the pin seat 9. When children use foreign objects to insert into the jack 7 during play, the levers 521 in two directions will not be driven to move at the same time. Any extension part of the lever 521 that has not moved will prevent the shell 8 from being pressed down to contact the pin seat 9 to power on, which is safer to use.

[0024] The on-off mechanism 6 includes a connecting plate 61, a paddle 62, a contact 63 and a spring 522. A cylindrical protrusion is provided on one side of the connecting plate 61 and a slope is provided on the other side. One end of the spring 522 is connected to the latch seat 9 and the other end is connected to the cylindrical protrusion. The paddle 62 is vertically connected to the connecting plate 61. The lower end of the paddle 62 is rotatably connected to the copper sheet clamping portion 10. The contact 63 is provided on the paddle 62 on the same side as the spring 522. The paddle 62 is a bent structure. The bent inclined surface is in the same direction as the inclined surface on the connecting plate 61, and the maximum bend is located at the lowest end of the jack 7. Figure 6 、 Figure 7As shown, the connecting plate 61 is slidably connected in the slide groove at the upper end of the pin seat 9, the connecting plate 61 is vertically connected to the socket 7 and blocks a part of the socket 7, a slope is provided on the end of the connecting plate 61 that blocks the socket 7, and the corresponding socket 7 is built-in, and the end of the slope extends to the top of the socket 7, and the cylindrical protrusion is provided on the side of the connecting plate 61 away from the slope. The cylindrical protrusion is connected to the pin seat 9 through a spring 522, and a paddle 62 is vertically connected to the connecting plate 61. The paddle 62 is parallel to the direction of the socket 7 and is rotatably connected to the copper sheet clamping part 10 at the bottom of the pin seat 9. A contact 63 is connected on the side of the paddle 62 away from the socket 7. At the same time, a flat portion at a small distance on the pin seat 9 Another contact 63 connected to the outside is provided. When the plug continues to be pressed down after passing through the lever 521, it will contact the connecting plate 61. The plug part first squeezes the slope, and continues to press down to move the connecting plate 61 to the end away from the socket 7, while squeezing the spring 522. When the pressure continues to be pressed down, the plug will contact the paddle 62. When the plug is pressed down to the bend of the paddle 62, it will continue to squeeze the inclined surface of the bend, so that the lower end of the paddle 62 and the copper sheet clamping part 10 are used as the rotation point to rotate toward the contact 63 at the right end. When the plug is fully inserted into the socket 7, that is, the plug and the maximum bend of the paddle 62 are squeezed so that the contact 63 connected to the paddle 62 is connected to the live contact 63 on the right, forming a loop power supply.

[0025] Working principle and usage steps:

[0026] 1. Self-locking of the float: When the socket is in a normal state without a plug inserted, the float 4 is in a pop-up state. When the plug is not inserted, the float 4 is under the action of the lever 521 and the spring 522, so that the lever 521 is always in an ejected state. When the float 4 is pressed, it cannot be pressed down, so that the float 4 is self-locking without a plug. When the plug is inserted, the plug will move along the inclined block 11 of the lever 521, and the lever 521 will be moved inward to unlock. At the same time, the spring 522 is compressed to store energy, so that the float 4 is inserted and unlocked. When the float 4 is pressed to the bottom, the unlocking button 3 is forced to pop out through the fulcrum 512. When the plug is inserted into the copper sheet, the unlocking button 3 is pressed and the float 4 pops out, so that the float 4 is self-locking.

[0027] 2. Power on after the plug is inserted: When the plug is not inserted, the paddle 62 is not subjected to force and is in a normal non-contact state. When the plug is inserted into the socket, it must first pass through the slope of the connecting plate 61, driving the paddle 62 connected to the connecting plate 61 to rotate on the copper sheet support portion. At the same time, the spring 522 is compressed to store energy. As the plug is inserted downward into the socket 7, the paddle 62 contacts the live contact 63, realizing insertion and power on. When the plug is pulled out, the connecting plate 61 is pushed outward by the spring 522, and the paddle 62 rotates along the copper sheet support portion to disengage, realizing pull-out and power off.

[0028] The present invention provides a limit assembly 52 on the pin seat 9, and blocks the socket 7 through the lever 521 therein to prevent children from accidentally touching it while playing. At the same time, the extension part at one end of the lever 521 will block the shell 2 in the float 4 from sliding downward to connect with the pin seat 9 under the action of the spring 522, so that the plug cannot contact the socket 7 of the pin seat 9 when in use, and there is no risk of electric shock when inserted.

[0029] At the same time, an on-off mechanism 6 is also provided on the plug seat 9. When in use, the plug needs to first contact the connecting plate 61 to displace it, and then continue to insert and displace the paddle 62 to rotate the contact 63 and connect with the live contact 63. Simply forcibly inserting a conductive object into the plug seat 9 will not be able to push the connecting plate 61 to move to the live contact 63 to energize. The simultaneous action of the self-locking mechanism and the on-off mechanism can effectively avoid the risk of electric shock.

Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
