Description

Technical Field

[0001] This invention relates to the field of smart socket technology, specifically to a smart energy-saving socket. Background Technology

[0002] Smart sockets are simply power-saving sockets. The concept of energy-saving sockets has been around for a long time and has become quite widespread, but the technology still needs further improvement. Some high-end energy-saving sockets not only save electricity but also protect electrical appliances. They can connect to handheld devices via Wi-Fi, Bluetooth, etc., and their main functions are remote switching and voice control.

[0003] The sockets of existing smart energy-saving sockets are generally in a normally open state. This not only makes it easy for dust and other debris to enter, causing problems such as circuit board failure, corrosion of electrode connecting pieces leading to increased resistance, and socket jamming due to debris, but also reduces the stability of the socket after prolonged plugging and unplugging, resulting in loose plugs and inability to charge. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an intelligent energy-saving socket that solves the problems of existing intelligent energy-saving sockets, such as the sockets being constantly open, leading to internal circuit board failures, increased resistance due to corrosion of electrode connecting pieces, sockets being easily jammed by debris, and decreased stability of the sockets after prolonged use.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a smart energy-saving socket, comprising a smart socket housing, wherein a plurality of five-hole sockets are provided on the top of the smart socket housing, an adjustment groove is provided on the top of the smart socket housing, the adjustment groove is located in front of the sockets, a rotation limiting component is provided inside the adjustment groove, a switch is fixedly connected to the top of the smart socket housing, the switch is located in front of the sockets and on the right side of the adjustment groove, and side grooves are provided on the left and right side walls inside the smart socket housing;

[0008] The rotation limiting assembly includes an adjusting component for adjusting the opening and closing of the socket, a sealing component for sealing the socket, a stabilizing component for stabilizing the plug, and a limiting component for limiting the adjusting component. The sealing component is installed behind the adjusting component, the stabilizing component is installed below the sealing component, and the limiting component is installed below the stabilizing component.

[0009] Preferably, the adjustment assembly includes an outer sleeve, a torsion spring, a helical gear, a ratchet, a pawl, an inner groove, a connecting rod, a return spring, a fixing plate, and a knob. The knob is located inside the adjustment groove. An outer sleeve is installed below the knob. A torsion spring is fixedly installed inside the outer sleeve. The inner end of the torsion spring is fixedly connected to the knob. A ratchet is fixedly connected to the bottom of the knob. A helical gear is fixedly connected to the bottom of the ratchet. A pawl is engaged with the outer side of the ratchet. An inner groove is formed on the pawl. A connecting rod is rotatably connected to the top of the pawl. A return spring is fixedly connected to the right side wall of the pawl. A fixing plate is fixedly connected to the right side wall of the return spring.

[0010] Preferably, the top of the fixing plate and the connecting rod are fixedly connected to the inner top surface of the smart socket housing, and the top of the outer sleeve is fixedly connected to the inner top surface of the smart socket housing.

[0011] By adopting the above technical solution, when the knob is rotated, a clicking sound is made between the ratchet and the pawl, and the ratchet causes the helical gear to rotate together. During the rotation, the torsion spring continuously accumulates elastic potential energy.

[0012] Preferably, the sealing assembly includes a limiting frame, a herringbone rack, a sealing plate, a sealing block, a slot, a side rod, and a guide plate. The limiting frame is fixedly connected to the inner top surface of the smart socket housing. The herringbone rack is slidably installed inside the limiting frame. The sealing plate is fixedly connected to the rear end of the herringbone rack. The sealing block is fixedly connected to the top of the sealing plate. The sealing plate has a slot. The side rods are fixedly connected to the left and right side walls of the sealing plate. A guide plate for guiding the movement of the side rods is installed below the side rods.

[0013] Preferably, the top of the guide plate is fixedly connected to the inner top surface of the smart socket housing, the top of the limiting frame is fixedly connected to the inner top surface of the smart socket housing, and the helical gear is located in front of the limiting frame and meshes with the helical rack on both sides.

[0014] By adopting the above technical solution, during the rotation of the knob, the helical gear drives the helical rack to move within the limit frame, and under the action of the guide rods on both sides, the sealing plate moves down, and under the action of the pawl, the socket is stably opened, making it convenient for the plug to be inserted.

[0015] Preferably, the stabilizing component includes a limiting plate, a slot, a sliding rod, and a guiding rod. The limiting plate is located below the sealing plate, and the limiting plate has a slot that is conical. Sliding rods are fixedly connected to the left and right side walls of the limiting plate, and the sliding rods are located inside the side slots. A guiding rod is fixedly connected to the front of the limiting plate.

[0016] By adopting the above technical solution, when the plug is inserted, the bottom of the plug presses down on the base plate, causing the other end of the rocker arm to tilt upwards, thereby lifting the transmission rod, which in turn causes the limiting plate to move upwards along the side groove. The slot stabilizes the plug, improving its stability.

[0017] Preferably, the limiting assembly includes a base plate, a rocker arm, a rotating block, a fixed seat, a vertical rod, a slide block, a limiting rod, and an upper spring. The base plate is located below the limiting plate. A rocker arm is fixedly connected to the front of the base plate. A rotating block is fixedly connected to the bottom of the rocker arm. A fixed seat is rotatably connected to the bottom of the rotating block. A vertical rod is installed on the top of the rocker arm. A slide block is slidably connected to the outer side of the vertical rod. A limiting rod is fixedly connected to the top of the vertical rod. An upper spring is fixedly connected to the top of the limiting rod.

[0018] By adopting the above technical solution, when the plug is inserted, the bottom of the plug presses down on the base plate, thereby causing the other end of the rocker arm to tilt upwards, which in turn causes the vertical rod to move upwards, releasing the limit rod from the pawl and thus fixing the ratchet, while the upper spring is in a compressed state.

[0019] Preferably, the bottom of both the slide and the fixed base are fixedly connected to the inner bottom surface of the smart socket housing.

[0020] By adopting the above technical solution, the slide is used to stabilize the rocker arm, and the fixed seat is used to guide the vertical rod to slide up and down.

[0021] Preferably, the limiting rod is located inside the inner groove.

[0022] By adopting the above technical solution, when the plug is pulled out, the vertical rod moves down under the action of the upper spring and releases the pawl from the ratchet.

[0023] Preferably, the top of the upper spring is fixedly connected to the inner top surface of the smart socket housing.

[0024] By adopting the above technical solution, when the rocker arm causes the vertical rod to move upward, it will compress the upper spring to deform. Thus, after the plug is pulled out, the vertical rod will move downward and reset under the action of the upper spring.

[0025] (III) Beneficial Effects

[0026] This invention provides an intelligent energy-saving socket. It has the following beneficial effects:

[0027] 1) When in use, rotate the knob. Under the action of the ratchet and pawl, a clicking sound is made. The torsion spring inside the outer sleeve absorbs the elastic potential energy. The helical gear drives the helical rack and sealing plate to move backward as the ratchet rotates, thereby separating the sealing block from the socket and opening the socket. When not in use, release the pawl. The torsion spring releases its elastic force, thereby causing the helical gear to rotate in the opposite direction, driving the sealing plate to move forward. The sealing block seals the socket, thereby closing the socket and preventing external debris from entering the socket and causing circuit board failure, electrode connection corrosion, socket blockage, etc.

[0028] 2) When in use, after the socket is opened, the plug is inserted into the socket. The bottom of the plug presses down on the base plate, causing the rocker arm to tilt upwards. The rocker arm lifts the transmission rod, causing the limit plate to move upwards. The slot on the limit plate locks the plug in place, thus stabilizing the plug and making it more stable.

[0029] 3) When in use, insert the plug into the socket and slot, press down the bottom plate and lift the other end of the rocker arm. The rocker arm pushes the vertical rod upward, and the limit rod above the vertical rod moves out of the inner groove, so that the pawl restricts the ratchet. This makes the helical gear in a ready-to-rotate state under the action of the torsion spring. The sealing plate also fits tightly with the pins on the plug, improving the stability of the plug. When the plug is pulled out, the vertical rod moves down under the action of the upper spring and releases the pawl from restricting the ratchet. The helical gear moves the sealing plate up quickly under the action of the torsion spring, sealing the socket. Attached Figure Description

[0040] Please see Figures 1 to 8 The present invention provides a technical solution: a smart energy-saving socket, including a smart socket housing 1, a circuit board installed inside the smart socket housing 1, a plurality of five-hole sockets 2 opened on the top of the smart socket housing 1, electrode connecting pieces corresponding to the sockets 2 installed inside the smart socket housing 1 for easy connection with plugs, an adjustment groove 3 opened on the top of the smart socket housing 1, the adjustment groove 3 being located in front of the sockets 2, a rotation limiting component 4 being provided inside the adjustment groove 3, a switch 5 being fixedly connected to the top of the smart socket housing 1, the switch 5 being located in front of the sockets 2 and to the right of the adjustment groove 3, and side grooves 6 being opened on the left and right side walls inside the smart socket housing 1.

[0042] The rotation limiting assembly 4 includes an adjustment assembly 401 for adjusting the opening and closing of the socket 2, a sealing assembly 402 for sealing the socket 2, a stabilizing assembly 403 for stabilizing the plug, and a limiting assembly 404 for limiting the adjustment assembly 401. The sealing assembly 402 is installed behind the adjustment assembly 401, the stabilizing assembly 403 is installed below the sealing assembly 402, and the limiting assembly 404 is installed below the stabilizing assembly 403.

[0043] Switch 5 is electrically connected to the internal circuit board of the smart socket housing 1. When switch 5 is turned on, the electrode connecting piece corresponding to switch 5 is connected to the circuit board, so that the socket 2 can be used.

[0044] The adjustment assembly 401 includes an outer sleeve 405, a torsion spring 406, a helical gear 407, a ratchet 408, a pawl 409, an inner groove 410, a connecting rod 411, a return spring 412, a fixing plate 413, and a knob 433. The knob 433 is located inside the adjustment groove 3. The outer sleeve 405 is installed below the knob 433. The torsion spring 406 is fixedly installed inside the outer sleeve 405. The inner end of the torsion spring 406 is fixedly connected to the knob 433. The bottom of the knob 433 is fixedly connected to the ratchet 408. A helical gear 407 is fixedly connected, and a pawl 409 is engaged on the outer side of a ratchet 408. An inner groove 410 is provided on the pawl 409. A connecting rod 411 is rotatably connected to the top of the pawl 409. A return spring 412 is fixedly connected to the right side wall of the pawl 409. A fixing plate 413 is fixedly connected to the right side wall of the return spring 412. The tops of the fixing plate 413 and the connecting rod 411 are fixedly connected to the inner top surface of the smart socket housing 1. The top of the outer sleeve 405 is fixedly connected to the inner top surface of the smart socket housing 1.

[0045] When the knob 433 is rotated, a clicking sound is made between the ratchet 408 and the pawl 409, and the ratchet 408 causes the helical gear 407 to rotate together. During the rotation, the torsion spring 406 continuously accumulates elastic potential energy.

[0046] The sealing assembly 402 includes a limiting frame 414, a helical rack 415, a sealing plate 416, a sealing block 417, a slot 418, a side rod 419, and a guide plate 420. The limiting frame 414 is fixedly connected to the inner top surface of the smart socket housing 1. The helical rack 415 is slidably installed inside the limiting frame 414. The sealing plate 416 is fixedly connected to the rear end of the helical rack 415. The sealing block 417 is fixedly connected to the top of the sealing plate 416. The slot 418 is provided on the sealing plate 416. The side rod 419 is fixedly connected to the left and right side walls of the sealing plate 416. The guide plate 420 for guiding the movement of the side rod 419 is installed below the side rod 419. The top of the guide plate 420 is fixedly connected to the inner top surface of the smart socket housing 1. The top of the limiting frame 414 is fixedly connected to the inner top surface of the smart socket housing 1. The helical gear 407 is located in front of the limiting frame 414 and meshes with the helical rack 415 on the left and right sides.

[0047] During the rotation of knob 433, helical gear 407 drives helical rack 416 to move within limit frame 414, and under the action of guide plates 420 on both sides, sealing plate 416 and side rod 419 move backward and downward, and under the action of pawl 409, the socket 2 is stably opened, making it convenient for plug to be inserted.

[0048] The stabilizing component 403 includes a limiting plate 421, a slot 422, a sliding rod 423, and a guiding rod 424. The limiting plate 421 is located below the sealing plate 416. The limiting plate 421 has a slot 422, which is conical. The sliding rod 423 is fixedly connected to the left and right side walls of the limiting plate 421. The sliding rod 423 is located inside the side groove 6. The guiding rod 424 is fixedly connected to the front of the limiting plate 421.

[0049] When the plug is inserted, the bottom of the plug presses down on the base plate 425, causing the other end of the rocker arm 426 to tilt upward, thereby lifting the transmission rod 424, which in turn causes the limiting plate 421 to move upward along the side groove 6. The slot 422 stabilizes the plug and improves its stability.

[0050] The limiting component 404 includes a base plate 425, a rocker arm 426, a rotating block 427, a fixed seat 428, a vertical rod 429, a slide block 430, a limiting rod 431, and an upper spring 432. The base plate 425 is located below the limiting plate 421. The rocker arm 426 is fixedly connected to the front of the base plate 425. The rotating block 427 is fixedly connected to the bottom of the rocker arm 426. The fixed seat 428 is rotatably connected to the bottom of the rotating block 427. The vertical rod 429 is installed on the top of the rocker arm 426. The outer side of the vertical rod 429 slides. A slide block 430 is connected to the bottom of both the slide block 430 and the fixed base 428, which are fixedly connected to the inner bottom surface of the smart socket housing 1. The slide block 430 is used to stabilize the rocker arm 426, and the fixed base 428 is used to guide the vertical rod 429 to slide up and down. A limit rod 431 is fixedly connected to the top of the vertical rod 429. The limit rod 431 is located inside the inner groove 410. An upper spring 432 is fixedly connected to the top of the limit rod 431, and the top of the upper spring 432 is fixedly connected to the inner top surface of the smart socket housing 1.

[0051] When the plug is inserted, the bottom of the plug presses down on the base plate 425, causing the other end of the rocker arm 426 to tilt upwards, thereby moving the vertical rod 429 upwards. The limiting rod 431 releases the restriction on the pawl 409, thus fixing the ratchet 408. The upper spring 432 is in a compressed state. When the plug is pulled out, the vertical rod 429 moves downwards under the action of the upper spring 432, causing the pawl 409 to release the restriction on the ratchet 408. The ratchet 408 and the helical gear 407 rotate in opposite directions under the action of the torsion spring 406.

[0052] Working principle: Before use, the socket 2 is sealed and the switch 5 is closed. When needed, switch 5 is turned on and knob 433 is rotated, causing a clicking sound between ratchet 408 and pawl 409. The ratchet 408 also causes helical gear 407 to rotate. During rotation, torsion spring 406 continuously accumulates elastic potential energy. Helical gear 407 drives helical rack 416 to move within limit frame 414. Under the action of guide plates 420 on both sides, sealing plate 416 and side rod 419 move backward and downward. Under the action of pawl 409, socket 2 is stably opened. When the plug is inserted into socket 2, the bottom of the plug presses down on base plate 425, causing the other end of rocker arm 426 to tilt upward, thereby lifting transmission rod 424. This causes limit plate 421 to move upward along side groove 6, and slot 422 engages with the plug. The head is stabilized to improve the stability of the plug connection. At the same time, the rocker arm 426 also moves the vertical arm 429 upward, and the limiting arm 431 moves out of the inner groove 410 to release the restriction on the pawl 409. The pawl 409 limits the ratchet 408. The torsion spring 406 is in a state of accumulating elastic potential energy and is in a stable state. The upper spring 432 is in a compressed state. When the plug is unplugged after use, the vertical arm 429 moves downward under the action of the upper spring 432 and releases the pawl 409 from the restriction on the ratchet 408. The ratchet 408 and the helical gear 407 rotate in opposite directions under the action of the torsion spring 406. The helical gear 407 drives the helical rack 415 to move upward. The sealing block 417 is inserted into the socket 2 to form a seal, preventing external debris from entering the socket from the socket 2 and causing circuit board failure, electrode connection corrosion, and socket 2 blockage.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
