Description

Technical Field

[0001] This utility model relates to the field of smart socket technology, specifically an extension cord socket with an anti-disconnection structure. Background Technology

[0002] Smart extension cords combine the convenience of traditional extension cords with modern IoT technology. Essentially a power strip with one or more outlets, its core value lies in its ability to connect to a home network via Wi-Fi or Bluetooth. Users can remotely control the switch status via a dedicated mobile app or voice assistant, enabling features such as timed on / off (e.g., setting a rice cooker's start time), countdown shutdown (e.g., preventing air conditioners from running overnight), scene linkage (e.g., a "away mode" to turn off all appliances with a single click), and electricity usage statistics. This significantly improves the convenience, safety, and energy-saving potential of home electricity usage.

[0003] Existing furniture sockets are generally less subject to change, unlike mobile device charging plugs which may be frequently plugged and unplugged. However, when cleaning, moving appliances, or when appliances vibrate during operation, the power cord is easily pulled, causing the power plug of the appliance to be affected by external force, which can easily lead to loosening or detachment, affecting the stability of the appliance's use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an extension cord socket with an anti-disconnection structure to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an extension cord socket with an anti-loosening structure, comprising a smart socket, wherein a base plate is connected to the bottom of the smart socket, and screws are fixed on both sides of the top of the base plate, and springs, anti-loosening nuts and anti-loosening washers are sleeved on the outside of the screws, and a pressure plate is connected between the spring and the anti-loosening washer, and an avoidance groove is provided on the outer surface of the pressure plate.

[0006] By adopting the above technical solution, after inserting the electrical plug into the socket, the user places the pressure plate, which can slide up and down the outer circle of the screw rod to facilitate adjusting the height of the pressure plate to fit electrical plugs of more body types, such as some electrical plugs with lower height or higher height. When the pressure plate contacts the top of the electrical plug and cannot move downwards, then place the anti-loosening gasket and tighten the anti-loosening nut, thereby reducing the occurrence of the pressure plate moving upwards. And due to the elastic force of the spring, it will continuously act among the anti-loosening nut, the anti-loosening gasket and the pressure plate, and its supporting effect makes the top of the pressure plate keep in contact pressure with the anti-loosening gasket, forming a stable axial pre-tightening force to improve the seismic resistance effect. And when the structure is affected by temperature, the metal parts will expand and contract thermally, and the elastic deformation of the spring can absorb these deformations, avoiding the generation of additional stress due to deformation of the rigid structure and protecting the structural integrity. After the anti-loosening nut is tightened, the electrical plug is pressed by the pressure plate, thereby effectively reducing the occurrence of the electrical plug falling off. If the electrical plug is a right-angled three-wire plug, that is, the electrical cable is perpendicular to the electrical plug, the pressure plate will not interfere with the electrical cable of the electrical appliance. If the electrical plug is a straight-in three-wire plug, that is, the electrical cable is parallel to the electrical plug, the electrical cable can pass through through the avoidance groove, thereby avoiding interference between the pressure plate and the electrical cable.

[0007] Further, the longitudinal section of the pressure plate is in a "U" shape.

[0008] By adopting the above technical solution, after inserting the electrical plug into the socket, place the pressure plate, and press the electrical plug through the pressure plate, thereby effectively reducing the occurrence of the electrical plug falling off.

[0009] Further, two of each of the screw rod, the spring, the anti-loosening nut and the anti-loosening gasket are provided, and the two screw rods, springs, anti-loosening nuts and anti-loosening gaskets are symmetrically distributed.

[0010] By adopting the above technical solution, the symmetrical structure enables the pressure plate to be stressed on both sides simultaneously, with good structural stability and high strength, so that it can be used for a long time.

[0011] Further, the pressure plate is slidably connected to the two screw rods, and the two springs and the two anti-loosening gaskets are both abutted against the pressure plate.

[0012] By adopting the above technical solution, the pressure plate can slide up and down the outer circle of the screw rod to facilitate adjusting the height of the pressure plate to fit electrical plugs of more body types, such as some electrical plugs with lower height or higher height. When the pressure plate contacts the top of the electrical plug, it cannot move downwards.

[0013] Further, the screw rod, the spring, the anti-loosening nut, the anti-loosening gasket, the pressure plate and the bottom plate are all made of 304 stainless steel material.

[0014] By adopting the above technical solution, the screw, spring, anti-loosening nut, anti-loosening washer, pressure plate and base plate are made of 304 stainless steel, which has good corrosion resistance, avoids rusting of the structure when the indoor humidity is high and affects the service life, and has higher strength than plastic materials.

[0015] Furthermore, the base plate is connected to the smart socket by bolts.

[0016] By adopting the above technical solution, the base plate is connected to the smart socket with bolts, which avoids the phenomenon of base plate displacement or detachment, thereby improving the stability of the screw.

[0017] Furthermore, the smart socket has a socket cord connected to its back and a socket on its top.

[0018] By adopting the above technical solution, users can plug the power plug from the socket cord into the wall socket, and use the socket cord as an extension cord to move the smart socket to the vicinity of the appliance's location, avoiding the appliance being unable to receive power due to being too far from the wall socket; then users can plug the appliance into the socket to receive power; the smart socket is equipped with wireless communication modules such as WiFi and Bluetooth, which can remotely control the physical connection or disconnection of the power supply to the internal current collector of the smart socket.

[0019] Furthermore, an electrical plug is provided at the top of the socket, and the electrical plug is a straight-plug three-wire plug or a right-angle three-wire plug.

[0020] By adopting the above technical solution, if the electrical plug is a right-angle three-prong plug, that is, the electrical cable is perpendicular to the electrical plug, the pressure plate will not interfere with the electrical cable. If the electrical plug is a straight-insertion three-prong plug, that is, the electrical cable is parallel to the electrical plug, the electrical cable can pass through the clearance groove, thereby avoiding interference between the pressure plate and the electrical cable.

[0021] Furthermore, the anti-loosening gasket consists of a flat gasket and a spring gasket.

[0022] By adopting the above technical solution, the anti-loosening washer composed of two washers is used to increase the connection stability between the anti-loosening nut and the pressure plate, effectively reducing the possibility of the anti-loosening nut loosening, and the redundant design extends the anti-loosening effect for a long time.

[0023] Furthermore, the bottom end of the screw is truncated cone-shaped.

[0024] By adopting the above technical solution, the contact area between the bottom of the screw and the base plate is increased, and the welding and fixing are more secure.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model, through the setting of a pressure plate and a clearance groove, allows the electrical plug to be inserted into the socket, and then the pressure plate is placed to hold the electrical plug in place, thereby effectively reducing the occurrence of the electrical plug falling off. If the electrical plug is a right-angle three-prong plug, that is, the electrical cable is perpendicular to the electrical plug, the pressure plate will not interfere with the electrical cable. If the electrical plug is a straight-insertion three-prong plug, that is, the electrical cable is parallel to the electrical plug, the clearance groove allows the electrical cable to pass through, thereby avoiding interference between the pressure plate and the electrical cable; thus effectively reducing the occurrence of the electrical plug falling off.

[0027] 2. This utility model, through the setting of a screw, anti-loosening nut, and anti-loosening washer, allows the pressure plate to slide up and down on the outer ring of the screw, so as to adjust the height of the pressure plate to adapt to more types of electrical plugs, such as some electrical plugs with lower or higher heights. When the pressure plate contacts the top of the electrical plug, it cannot move down. Then, the anti-loosening washer is placed and the anti-loosening nut is tightened, thereby reducing the phenomenon of the pressure plate moving up; it is easy to adjust to adapt to more types of electrical plugs.

[0028] 3. This utility model, through the setting of springs, ensures that the elastic force of the springs continuously acts between the anti-loosening nut, anti-loosening washer, and pressure plate, and its supporting effect keeps the top of the pressure plate and the anti-loosening washer in contact pressure, forming a stable axial preload and improving the seismic resistance; and when the structure is affected by temperature, the metal parts will expand and contract with temperature, and the elastic deformation of the springs can absorb these deformations, avoiding additional stress on the rigid structure due to deformation, protecting the structural integrity, and improving the structural stability.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] Example 1:

[0038] An extension cord socket with an anti-disconnection structure, such as Figures 1-5 As shown, the device includes a smart socket 1, with a base plate 10 connected to its bottom. The base plate 10 is connected to the smart socket 1 by bolts. Screws 4 are fixed to both sides of the top of the base plate 10. Springs 5, anti-loosening nuts 6, and anti-loosening washers 7 are sleeved on the outside of each screw 4. Two screws 4, springs 5, anti-loosening nuts 6, and anti-loosening washers 7 are provided, symmetrically distributed. A pressure plate 8 connects the springs 5 ​​and the anti-loosening washers 7, and the pressure plate 8 is slidably connected to the two screws 4. The two springs 5 ​​and the two... Each anti-loosening washer 7 abuts against the pressure plate 8. The longitudinal section of the pressure plate 8 is "U"-shaped, and the outer surface of the pressure plate 8 has a clearance groove 9. The screw 4, spring 5, anti-loosening nut 6, anti-loosening washer 7, pressure plate 8, and base plate 10 are all made of 304 stainless steel. After the electrical plug 11 is inserted into the socket 3, the user places the pressure plate 8. The pressure plate 8 can slide up and down on the outer ring of the screw 4 to adjust the height of the pressure plate 8 to accommodate more types of electrical plugs 11, such as some lower or higher electrical plugs 11. When the pressure plate 8 contacts the top of the electrical plug 11, it cannot move downwards. Then, the anti-loosening washer 7 is placed and the anti-loosening nut 6 is tightened, thus reducing the upward movement of the pressure plate 8. Furthermore, the elastic force of the spring 5 continuously acts between the anti-loosening nut 6, the anti-loosening washer 7, and the pressure plate 8, and its supporting effect keeps the top of the pressure plate 8 and the anti-loosening washer 7 in contact, forming a stable axial preload and improving the shock resistance. Moreover, when the structure is affected by temperature, the metal parts will expand and contract; the elastic deformation of the spring 5 can absorb these deformations, preventing... The rigid structure generates additional stress due to deformation, protecting the structural integrity. After the anti-loosening nut 6 is tightened, it presses the electrical plug 11 through the pressure plate 8, thereby effectively reducing the occurrence of the electrical plug 11 falling off. If the electrical plug 11 is a right-angle three-wire plug, that is, the electrical cable is perpendicular to the electrical plug 11, the pressure plate 8 will not interfere with the electrical cable. If the electrical plug 11 is a straight-insertion three-wire plug, that is, the electrical cable is parallel to the electrical plug 11, the clearance groove 9 allows the electrical cable to pass through, thereby avoiding interference between the pressure plate 8 and the electrical cable.

[0039] See Figure 1 , Figure 2 and Figure 5In the above embodiment, the smart socket 1 is connected to a socket cord 2 on its back, and a socket 3 is provided on the top of the smart socket 1. An appliance plug 11 is provided on the top of the socket 3. The appliance plug 11 is a straight-plug three-prong plug or a right-angle three-prong plug. The user plugs the power plug on the socket cord 2 into the wall socket, and uses the socket cord 2 as an extension cord to move the smart socket 1 to the vicinity of the appliance's location, so as to avoid the appliance being unable to be powered due to being too far away from the wall socket. Then the user can insert the appliance plug 11 into the socket 3 to turn on the power. The smart socket 1 is equipped with wireless communication modules such as WiFi and Bluetooth, which can remotely control the physical connection or disconnection of the power supply of the current collector inside the smart socket 1.

[0040] Example 2:

[0041] Based on the above embodiment one, the following settings are now adopted to enhance the anti-loosening effect.

[0042] See Figure 1 , Figure 3 , Figure 4 and Figure 5 In the above embodiment, the anti-loosening washer 7 is composed of a flat washer and a spring washer. The anti-loosening washer 7 is composed of two washers, which increases the connection stability between the anti-loosening nut 6 and the pressure plate 8, effectively reduces the possibility of the anti-loosening nut 6 loosening, and the redundant design extends the anti-loosening function for a long time.

[0043] Example 3:

[0044] Based on the above embodiment one, the following settings are now adopted to increase the stability of the structure.

[0045] See Figure 2 and Figure 4 In the above embodiment, the bottom end of the screw 4 is frustum-shaped. By increasing the bottom diameter of the screw 4, the contact surface between the bottom of the screw 4 and the base plate 10 is larger, and the welding and fixing are more secure.

[0046] The implementation principle of this utility model is as follows: First, the user plugs the power plug on the socket line 2 into the wall socket. Using the socket line 2 as an extension line, the smart socket 1 can be moved to the vicinity of the appliance's location to avoid the appliance being unable to receive power due to being too far from the wall socket. Then, the user can insert the appliance plug 11 into the socket 3 to turn on the power. The smart socket 1 is equipped with wireless communication modules such as WiFi and Bluetooth, which can remotely control the physical connection or disconnection of the power supply of the current collector inside the smart socket 1.

[0047] After inserting the electrical plug 11 into the socket 3, the user places the pressure plate 8. The pressure plate 8 can slide up and down on the outer ring of the screw 4 to adjust its height to accommodate electrical plugs 11 of various sizes, such as those that are shorter or taller. Once the pressure plate 8 contacts the top of the electrical plug 11, it cannot move downwards. Then, the anti-loosening washer 7 is placed and the anti-loosening nut 6 is tightened to reduce the upward movement of the pressure plate 8. The elastic force of the spring 5 continuously acts between the anti-loosening nut 6, the anti-loosening washer 7, and the pressure plate 8, and its supporting effect keeps the top of the pressure plate 8 and the anti-loosening washer 7 in contact, forming a stable axial preload. It has high seismic resistance; and when the structure is affected by temperature, the metal parts will expand and contract with temperature. The elastic deformation of the spring 5 can absorb these deformations, avoid the rigid structure from generating additional stress due to deformation, protect the structural integrity, and after the anti-loosening nut 6 is tightened, it presses the electrical plug 11 through the pressure plate 8, thereby effectively reducing the occurrence of the electrical plug 11 falling off. If the electrical plug 11 is a right-angle three-wire plug, that is, the electrical cable is perpendicular to the electrical plug 11, the pressure plate 8 will not interfere with the electrical cable. If the electrical plug 11 is a straight-insertion three-wire plug, that is, the electrical cable is parallel to the electrical plug 11, the electrical cable can pass through the clearance groove 9, thereby avoiding interference between the pressure plate 8 and the electrical cable.
