Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a multifunctional power strip. Background Art

[0002] A power strip, also called an extension cord, has a socket, a plug and a power cord. It is an electrical product that extends the distance and expands multiple sockets, allowing users to connect multiple electrical appliances for use at the same time. With the development of technology, people need to charge more and more electronic products. Ordinary power strips can no longer meet people's needs. Therefore, different sockets are provided on the power strip to accommodate different types of plugs.

[0003] At present, a Chinese utility model patent application with a publication date of January 8, 2019 and publication number CN208352567U applies for a socket with a rotatable socket hole. Its structure includes a socket bottom shell, a slide groove, a socket top shell, a status indicator light, a socket plug, a power switch, and a power cord. In this utility model, the power cord is connected to a 220V power supply, and the power switch is pressed to power on the socket. At this time, the socket head is not powered on, which can ensure that accidents of accidental touch are avoided when not in use. The socket head is pressed and the socket column is rotated so that the positioning column slides into the sliding groove and is fixed. The conductive position touches the conductive sheet and squeezes the reset spring, thereby powering on the socket head.

[0004] However, this rotatable socket is arranged on the socket board housing, and the plug is directly exposed to the air. Repeated plugging and unplugging, as well as the possibility that the user may collide with the plug, may cause the plug to become loose, which may lead to electric shock accidents, which is very dangerous. Utility Model Content

[0005] In order to improve the safety of a power strip, the utility model provides a multifunctional power strip.

[0006] A multifunctional power strip. The utility model provides a multifunctional power strip, comprising a base, a shell, a conduction mechanism and a fixing mechanism, wherein the shell is arranged on the base, a placement cavity is formed between the shell and the base, a plug-in slot, a power connection hole and a limit hole are provided on the shell, the fixing mechanism comprises a connecting plate and a clamping plate, the connecting plate is arranged on the base, one end of the clamping plate is arranged on the connecting plate, the other end of the clamping plate passes through the limit hole and abuts against the shell, the clamping plate is made of elastic material, the conduction mechanism is arranged on the base, and the conduction mechanism is in the placement cavity.

[0007] By adopting the above technical solution, when using the socket strip, the power cord is connected to the conduction mechanism to power the socket strip, and then the plug is inserted into the wire slot so that the conductive part of the plug is inserted into the power receiving hole. Since the clamp is made of elastic material, the clamp will clamp the plug at this time, and the plug will not loosen easily, thereby reducing the probability of the plug falling from the socket strip and reducing the probability of electric shock accidents.

[0008] Optionally, a first guide block and a second guide block are further provided on the shell, and the first guide block and the second guide block are both located in the plug-in groove, and the first guide block and the second guide block form a guide slide groove.

[0009] By adopting the above technical solution, after the user inserts the plug into the power connection hole along the direction of the first guide block and the second guide block in the socket slot, the insertion direction of the plug will be fixed. When the user then inserts the second and third plugs into the power strip, since the direction of each socket is set in the same way, the wires of the plugs will also be arranged uniformly, which can effectively prevent the safety hazards caused by messy wiring, and the insertion of the plug into the power strip shell can effectively reduce the possibility of the plug becoming loose when the power strip collides.

[0010] Optionally, the fixing mechanism also includes a connecting block, an insulating block, a paddle and a torsion spring, the connecting plate is arranged on the base, the connecting block is provided with a placement groove, the insulating block is arranged in the placement groove, the insulating block is provided with a through hole, the paddle is rotatably connected to the insulating block, one end of the torsion spring is arranged on the connecting block, and the other end of the torsion spring abuts against the paddle.

[0011] By adopting the above technical solution, after the user inserts the plug into the power connection hole along the direction of the first guide block and the second guide block, the plug will pass through the pick on the insulating block and insert into the conductive sheet. At this time, the torsion spring under the pick will clamp the plug under the action of elastic force, effectively preventing the plug from loosening. After using the power strip, the user pulls out the plug. Since children are curious and have weak safety awareness, they are likely to insert their fingers into the socket and cause electric shock accidents. However, the torsion spring in the power strip of the utility model will shrink and drive the pick to close. At this time, the bottom of the power socket and the conductive sheet are separated by the pick on the insulating block, reducing the possibility of electric shock accidents caused by users or children not touching the socket.

[0012] Optionally, the through hole and the power connection hole are on the same vertical line.

[0013] By adopting the above technical solution, the user can save effort and feel more convenient when inserting the power connection hole along the direction of the first guide block and the second guide block.

[0014] Optionally, the conduction mechanism includes two conductive sheets and a power-off switch, wherein the conductive sheets are arranged on the base, and both ends of the conductive sheets are fixedly connected to the connection between the base and the shell, and the power-off switch is arranged at one end of the base, and the power-off switch is placed in the cavity.

[0015] By adopting the above technical solution, one end of the power cord is connected to the power-off switch, and two leads are pulled out from the other end of the power-off switch and connected to two conductive plates. After the user turns on the power cord, the power-off switch can directly control the closing and opening of the internal circuit of the power strip. After the user stops using the power strip, there is no need to unplug the plugs one by one, and the circuit can be disconnected by directly pressing the power-off switch. When it is needed, it is only necessary to press the power-off switch again, which improves the user's usage efficiency while reducing the possibility of electric shock accidents in the power strip, thereby improving the safety of the power strip.

[0016] Optionally, a USB interface is further provided on the base, and the USB interface is arranged at an end away from the power off switch. A long hole is also provided on the shell, and the USB interface passes through the long hole and is flush with the top of the shell.

[0017] By adopting the above technical solution, with the development of science and technology, more and more electronic products need to be charged. When multiple chargers are plugged into a power strip, adjacent sockets are easily blocked, causing inconvenience to users. The utility model directly provides a USB interface and a Type-C interface for charging electronic products, and the USB interface can support a power of 18W, and the Type-C interface can support a power of up to 20W, which not only saves the space occupied by the power strip when users charge electronic products, but also ensures the charging efficiency of users.

[0018] Optionally, the shell and the base are arranged on a fixed plate away from one end of the USB interface, and a clamping plate is also arranged on the fixed plate. A guide groove is opened at the connection between the shell and the base, and an annular gasket is arranged on the guide groove.

[0019] By adopting the above technical solution, users may need to move the power strip when using it. Many people will directly lift the power cord to move the power strip, causing the power cord and the power strip to loosen. The utility model provides a clamping plate at the place where the power cord and the power strip are connected, so that even if the user directly lifts the power strip by the power cord, it can effectively prevent loosening. In addition, an annular gasket is provided on the outer shell, which greatly reduces the loss caused by friction between the power cord and the power strip and increases the service life of the power strip.

[0020] In summary, the present invention includes at least one of the following beneficial technical effects:

[0021] 1. The power strip has a clamping plate, which is made of elastic material. After the user inserts the plug into the power port, the clamping plate will clamp the plug tightly, and the plug will not loosen easily, and the probability of electric shock accidents will be greatly reduced.

[0022] 2. All plugs will be inserted into the power strip in the same direction, which can effectively prevent the safety hazards caused by messy wiring. And the plugs will be inserted into the power strip shell, which can effectively reduce the possibility of the plugs becoming loose when the power strip collides.

[0023] 3. As children are more curious and less aware of safety, they are likely to insert their fingers into the socket, causing electric shock accidents. The torsion spring in the power strip of the utility model will drive the paddle to close. At this time, the bottom of the power socket and the conductive sheet are separated by the paddle on the insulating block, reducing the possibility of electric shock accidents caused by users or children not touching the socket.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] This embodiment discloses a multifunctional power strip: Figure 1-Figure 5A multifunctional power strip includes a base 1, a shell 2, a conducting mechanism and a fixing mechanism. The shell 2 is connected to the base 1 by screws. A placement cavity is formed between the shell 2 and the base 1. The conducting mechanism and the fixing mechanism are both arranged in the placement cavity. The conducting mechanism is used for transmitting electricity, and the fixing mechanism is used for fixing the plug.

[0032] Reference Figure 1-Figure 5 The conduction mechanism includes two conductive sheets 31 and a power-off switch 32. The conductive sheets 31 are connected to the base 1 by screws. Both ends of the conductive sheets 31 are fixedly connected to the connection between the base 1 and the shell 2. The power-off switch 32 is connected to one end of the base 1 by screws, and the power-off switch 32 is placed in the cavity. A USB interface 33 is also provided on the base 1. The USB interface 33 is connected to the end away from the power-off switch 32 by bolts. A long hole 21 is also provided on the shell 2. The USB interface 33 passes through the long hole 21 and is flush with the top of the shell 2.

[0033] One end of the power cord is connected to the power-off switch 32, and the other end of the power-off switch 32 pulls out two leads and connects to the two conductive sheets 31. After the user turns on the power cord, the power-off switch 32 can directly control the closing and disconnection of the internal circuit of the power strip. After the user stops using the power strip, there is no need to unplug the plugs one by one. The circuit can be disconnected by directly pressing the power-off switch 32. When it is needed, it only needs to press the power-off switch 32 again, which improves the user's efficiency and reduces the possibility of electric shock accidents in the power strip, thereby improving the safety of the power strip. With the development of science and technology, more and more electronic products need to be charged. When multiple chargers are plugged into the power strip, adjacent sockets are easily blocked, which brings inconvenience to users. The utility model directly provides a USB interface 33 and a Type-C interface for charging electronic products, and the USB interface 33 can support a power of 18W, and the Type-C interface can support a power of up to 20W, which not only saves the space occupied by the user when charging electronic products, but also ensures the charging efficiency of the user.

[0034] Reference Figure 1-Figure 5The shell 2 is provided with a plug slot 22, a power connection hole 23 and a limit hole 24, the fixing mechanism includes a connecting plate 41, a clamping plate 42, a connecting block 43, an insulating block 44, a paddle 45 and a torsion spring 46, the connecting plate 41 is arranged on the base 1, one end of the clamping plate 42 is arranged on the connecting plate 41, and the other end of the clamping plate 42 passes through the limit hole 24 and abuts against the shell 2, the clamping plate 42 is made of elastic material, and the clamping plate 42 and the connecting plate 41 are integrally formed; the shell 2 is also provided with a first guide block 25 and a second guide block 26, the first guide The guide block 25 and the second guide block 26 are both located in the plug-in slot 22. The first guide block 25 and the second guide block 26 are formed integrally with the housing 2. The first guide block 25 and the second guide block 26 form a guide slot 27. The connecting block 43 is arranged on the base 1. A placement slot 47 is provided on the connecting block 43. The insulating block 44 is arranged in the placement slot 47. A through hole 48 is provided on the insulating block 44. The paddle 45 is rotatably connected to the insulating block 44. One end of the torsion spring 46 is arranged on the connecting block 43. The other end of the torsion spring 46 abuts against the paddle 45. The through hole 48 and the power connection hole 23 are on the same vertical line.

[0035] When using the power strip, connect the power cord to the conducting mechanism to supply power to the strip, and then insert the plug into the socket slot so that the conductive part of the plug is inserted into the power receiving hole 23. Since the clamp 42 is made of elastic material, the clamp 42 will clamp the plug at this time, and the plug will not be easily loosened, thereby reducing the probability of the plug falling off the strip and reducing the probability of electric shock accidents. At the same time, after the user inserts the plug into the power receiving hole 23 along the direction of the first guide block 25 and the second guide block 26 in the socket slot 22, the direction of the plug insertion will be fixed. When the user inserts the second and third plugs into the strip, since the direction of each socket is the same, the wires of the plugs will also be arranged uniformly, which can effectively prevent the safety hazards caused by messy wiring, and the plug is inserted into the strip housing 2, which can effectively reduce the situation where the plug is loosened when the strip collides. After the plug is inserted into the power-on hole, it will pass through the paddle 45 on the insulating block 44 and insert into the conductive sheet 31. At this time, the torsion spring 46 under the paddle 45 will clamp the plug under the action of elastic force, effectively preventing the plug from loosening. After using the power strip, the user unplugs the plug. Since children are curious and have weak safety awareness, they are likely to insert their fingers into the socket and cause electric shock accidents. However, the torsion spring 46 in the power strip of the utility model will shrink and drive the paddle 45 to close. At this time, the bottom of the power port and the conductive sheet 31 are separated by the paddle 45 on the insulating block 44, reducing the possibility of electric shock accidents caused by users or children not touching the socket.

[0036] Reference Figure 1-Figure 2The housing 2 and the base 1 are arranged on a fixing plate 5 at one end away from the USB interface 33, and a clamping plate 6 is also arranged on the fixing plate 5. A guide groove 7 is opened at the connection between the housing 2 and the base 1, and an annular gasket 8 is arranged on the guide groove 7.

[0037] When using a power strip, a user may need to move the power strip. Many people will directly lift the power cord to move the power strip, causing the power cord and the power strip to loosen. The utility model provides a clamping plate 6 at the place where the power cord and the power strip are connected, so that even if the user directly lifts the power strip by the power cord, it can effectively prevent loosening. In addition, an annular gasket 8 is also provided on the housing 2, which greatly reduces the loss caused by friction between the power cord and the power strip and increases the service life of the power strip.

[0038] The implementation principle of a multifunctional power strip in this embodiment is as follows:

[0039] When the user needs to use the power strip, he needs to first insert the plug on the power cord into the socket that is already powered. At this time, the power-off switch 32 needs to be turned on, so that the current will flow to the conductive sheet 31 through the power-off switch 32, and the other end of the conductive sheet 31 will connect two wires to pass the current to the USB interface 33. At this time, the checked socket and the USB interface 33 are both powered on. The user only needs to insert the plug into the power connection hole 23 along the direction of the first guide block 25 and the second guide block 26. The plug will press the paddle 45 on the insulating block 44 down and insert it into the conductive sheet 31. At the same time, the clamp 42 on the fixing mechanism will clamp the plug, and the torsion spring 46 under the paddle 45 will also clamp the plug under the action of the rebound force, effectively preventing the plug from loosening. After the user does not need to use the power strip to pull up the plug, the paddle 45 will close under the elastic force of the torsion spring 46 to prevent people from accidentally touching the power connection hole 23 and causing electric shock accidents.

[0040] When the user needs to move the power strip, the user can directly lift the power cord to move it. On the one hand, the power cord connection is fixed with a clamping plate 6, and on the other hand, the design of the annular gasket 8 can also reduce the damage to the power cord and the power strip caused by collision during movement.

[0041] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
