Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliances, in particular to an extendable hidden refrigerator socket and a use method thereof. Background Art

[0002] A socket, also known as a power socket or a switch socket, refers to a seat into which one or more circuit wiring can be inserted. Various wiring can be inserted through it, making it convenient to connect with other circuits. The connection and disconnection between the circuit and the copper parts can ultimately achieve the connection and disconnection of this part of the circuit.

[0003] However, the existing refrigerator socket lacks overload protection when in use, and the installation operation is relatively cumbersome, extremely inconvenient to use, and is prone to accidental touch, causing safety hazards; therefore, it does not meet the existing needs. In this regard, we propose an extendable hidden refrigerator socket and a method of using it. Summary of the Invention

[0004] The purpose of the present invention is to provide an extendable hidden refrigerator socket and a method for using the same, so as to solve the problems of the refrigerator socket proposed in the above background technology, which lacks overload protection during use, is cumbersome to install and operate, is extremely inconvenient to use, is prone to accidental touch, and poses a safety hazard.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: an extendable hidden refrigerator socket and a method for using the same, comprising a bottom box, a conductive box fixedly mounted on one end of the bottom box, anti-slip plates provided at both upper and lower ends of the bottom box, plug-in mechanisms provided on both sides of the inner wall of the bottom box, conductive structures symmetrically mounted on the outer surface of one end of the conductive box, and an overload protection device fixedly mounted between the two conductive structures;

[0006] The bottom box includes an outer shell, an inner cavity, a positioning groove, a conductive seat, a line connection end and a through-hole groove. The inner cavity is provided inside the outer shell, and two positioning grooves are provided at the upper and lower ends of the inner wall of the inner cavity. The outer surface of one end of the outer shell is symmetrically provided with two through-hole grooves. One end of the inner shell is symmetrically installed with two line connection ends, and one end of each line connection end is provided with a conductive seat. The conductive box includes a connecting box body, a slide groove, a positioning bar, a fixing pin, a toggle pin, a conductive end, an extension spring column, a power input line and a power output line. Slide grooves are provided on both sides of the connecting box body, and fixing pins are provided inside the slide grooves. Two positioning bars are provided at the upper and lower ends of the connecting box body, and a toggle pin is provided on one side of the fixing pin. Two conductive ends are symmetrically installed at one end of the connecting box body, and an extension spring column is fixedly installed at one end of the positioning bar. The power input line is fixedly installed at one end of the extension spring column. The upper end of the power input line is fixedly installed with a power on the overload protection side. The cam is connected to the drive means by a spring, and the cam is connected to the drive means by a spring.

[0007] Preferably, the ratchet comprises a sprocket and a support shaft, the upper surface of the sprocket is provided with a shift rod, the inner wall of the sprocket is provided with ratchet teeth, and the outer layer of the support shaft is movably connected with two pawls.

[0008] Preferably, the outer shell and the connection box body are fixedly connected via a plug-in mechanism, and the outer shell and the connection box body are connected via a positioning groove that cooperates with the connection box body to limit the connection.

[0009] Preferably, the conductive end is connected to the connection box body by sliding, and the conductive end is electrically connected to the conductive seat.

[0010] Preferably, the brake push rod is connected to the ratchet by tooth groove engagement, and the brake push rod is fixed to the brake pin by plugging.

[0011] Preferably, when the ratchet rotates counterclockwise, the ratchet and the support shaft are in an active state, and when it rotates clockwise, it is in a braking state.

[0012] Preferably, the width of one end of the plug-in bar is consistent with the width of the sliding groove, and the width of one side of the positioning bar is smaller than the width of the other side of the positioning bar.

[0013] An extendable hidden refrigerator socket: the method of using the same comprises the following steps:

[0014] 1. When fixing the device, first make a groove at the designated position of the wall, then fix the bottom box at the designated position in the groove, and connect the live and neutral wires to the line connection ends respectively in advance to complete the operation. The anti-drop plate can be used to clamp it, and one end of the connection box body is aligned with the inside of the inner cavity. Insert the connection box body into the inner cavity, and ensure that the connection box body is stuck in the inside of the positioning groove, and make the conductive end and the conductive seat conductively contact to complete the fixing operation. At the same time, the connection box body is fixed by the plug-in mechanism;

[0015] 2. When the plug-in bar slides into the interior of the slide groove, the brake pin is first squeezed inward through the slide groove to make the brake pin consistent with the width of the slide groove. At this time, the brake slot and the brake push rod are not in the same position. When the brake pin extends to the position of the positioning bar, the brake pin rebounds and is stuck in the interior of the positioning bar to form a fixed state. When the device is removed, press the connecting box body to extend the plug-in bar to the top of the slide groove. When the brake pin is stuck in the top of the slide groove, it will further shrink inward, so that the brake slot and the brake push rod are in the same horizontal position, and the ejection spring and the ratchet rotate counterclockwise to the active state, and clockwise When the cam is in the braking state, the brake push rod is extended to the inside of the brake slot and the brake slot is braked, so that the connecting box body can be withdrawn outwards. When withdrawing, when the ratchet moves to the position of the toggle pin, the toggle rod at the upper end of the ratchet is facing left, and after passing the toggle pin, it will be toggled to the right. When toggling to the right, the ratchet and the support shaft inside the ratchet are in the braking state, which will toggle the brake push rod back, so that the brake push rod is withdrawn from the inside of the brake slot, so that the brake pin realizes outward tension, and the toggle pin is small in size and will not affect the sliding effect of the brake pin in the slide slot. At this time, the removal operation is completed;

[0016] 3. When the connection box is inside the outer shell, the conductive seat transmits power to the conductive end, then transmits it to the inside of the power input line, and then transmits it to the inside of the overload protection, and then the overload protection transmits power to the two conductive structures;

[0017] 4. When the plug is inserted into the plug pin slot, the iron of the plug reacts with the magnetic rod, causing the magnetic rod to move toward the pin, and the length of the power transmission end is greater than the length of the magnetic rod. When the power transmission end contacts the outer surface of the pin, the magnetic rod does not contact the outer surface of the pin. When the pin is pulled out, the magnetic rod is returned to its original position by the retraction spring.

[0018] Preferably, the extended length of the power transmission end is greater than the extended length of the magnetic rod.

[0019] Preferably, the upper and lower ends of the magnetic rod are connected to the upper and lower ends of the inner wall of the inner groove by sliding.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention enables the device to achieve the function of plugging and fixing the device, and can be quickly taken out and inserted into the wall for hidden installation. It is simple to operate and easy to use, and an anti-accidental touch structure is added to prevent children from being electrocuted when touching the socket. BRIEF DESCRIPTION OF THE DRAWINGS

The power transmission end 506 is fixedly installed inside the magnetic rod 504, and the power access line 507 is fixedly installed at one end of the power transmission end 506.

[0034] Furthermore, the ratchet 406 includes a sprocket and a support shaft. A lever is provided on the upper surface of the sprocket, a ratchet is provided on the inner wall of the sprocket, and two pawls are movably connected to the outer layer of the support shaft. Through this mechanism, the device can be conveniently fixed.

[0035] Furthermore, the outer shell 101 and the connection box body 201 are fixedly connected via the plug-in mechanism 4 , and the outer shell 101 and the connection box body 201 are limitedly connected via the positioning groove 103 and the connection box body 201 . Through this mechanism, the connection box body 201 can be limited.

[0036] Furthermore, the conductive end 206 is connected to the connection box body 201 through sliding, and the conductive end 206 is electrically connected to the conductive seat 104. Through this mechanism, the function of power transmission can be achieved.

[0037] Furthermore, the brake push rod 405 is engaged with the ratchet 406 through the tooth groove, and the brake push rod 405 is fixed to the brake pin 402 by plugging. Through this mechanism, the automatic pop-up and retraction function of the device can be realized.

[0038] Furthermore, when the ratchet 406 rotates counterclockwise, the ratchet and the support shaft are in an active state, and when it rotates clockwise, it is in a braking state. Through this mechanism, the brake push rod 405 can be rebounded.

[0039] Furthermore, the width of one end of the plug-in bar 401 is consistent with the width of the slide groove 202, and the width of one side of the positioning bar 203 is smaller than the width of the other side of the positioning bar 203. Through this mechanism, the fixing effect of the device can be achieved.

[0040] An extendable hidden refrigerator socket: its use method includes the following steps:

[0041] 1. When fixing the device, first make a groove at the designated position of the wall, then fix the bottom box 1 at the designated position in the groove, and connect the live and neutral wires to the line connection terminals 105 in advance, and complete the operation. The anti-drop plate 3 can be used to clamp it, and one end of the connection box body 201 is aligned with the interior of the inner cavity 102, and the connection box body 201 is inserted into the interior of the inner cavity 102, while ensuring that the connection box body 201 is snapped into the interior of the positioning groove 103, and the conductive end 206 is in conductive contact with the conductive seat 104, completing the fixing operation. At the same time, the connection box body 201 is fixed by the plug-in mechanism 4;

[0042] 2. When the connecting rod 401 slides into the interior of the slide groove 202, the brake pin 402 is first squeezed inward through the slide groove 202, so that the brake pin 402 is consistent with the width of the slide groove 202, and at this time, the brake slot 408 and the brake push rod 405 are not flush with each other. When the brake pin 402 extends to the position of the positioning bar 203, the brake pin 402 rebounds and is stuck in the interior of the positioning bar 203 to form a fixed state. When the device is removed, the connecting box body 201 is pressed to extend the connecting rod 401 to the top of the slide groove 202. When the brake pin 402 is stuck in the top of the slide groove 202, it will further shrink inward, so that the brake slot 408 and the brake push rod 405 are at the same horizontal position, and the ejection spring 407 and the ratchet 406 are rotated counterclockwise to When the cam 405 is in the active state, the clockwise rotation is the braking state, which makes the brake push rod 405 extend to the inside of the brake slot 408 and realizes the braking operation on the brake slot 408, so that the connecting box body 201 can be withdrawn outwards. When withdrawing, when the ratchet 406 moves to the position of the toggle pin 205, the toggle rod state at the upper end of the ratchet 406 is facing left, and after passing the toggle pin 205, it will be toggled to the right. When toggling to the right, the ratchet and the support shaft inside the ratchet 406 are in the braking state, which will toggle the brake push rod 405 back, so that the brake push rod 405 is withdrawn from the inside of the brake slot 408, so that the brake pin 402 realizes outward tension, and the toggle pin 205 is small in size and will not affect the sliding effect of the brake pin 402 in the slide groove 202. At this time, the removal operation is completed;

[0043] 3. When the connection box 201 is inside the outer shell 101, the conductive base 104 transmits power to the conductive end 206, which then transmits power to the inside of the power input line 208. The power input line 208 then transmits power to the inside of the overload protection 6, which then transmits power to the two conductive structures 5.

[0044] 4. When the plug is inserted into the plug pin slot 502, the iron of the plug reacts with the magnetic rod 504, causing the magnetic rod 504 to move toward the plug. In addition, the length of the power transmission end 506 is greater than the length of the magnetic rod 504. When the power transmission end 506 contacts the outer surface of the plug, the magnetic rod 504 does not contact the outer surface of the plug. When the plug is pulled out, the magnetic rod 504 is returned to its original position by the retraction spring 505.

[0045] Furthermore, the extended length of the power transmission end 506 is greater than the extended length of the magnetic rod 504 . Through this mechanism, the magnetic rod 504 can be prevented from contacting the latch.

[0046] Furthermore, the upper and lower ends of the magnetic rod 504 are connected to the upper and lower ends of the inner wall of the inner groove 503 by sliding. Through this mechanism, the sliding effect of the magnetic rod 504 can be achieved.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
