Description

Technical Field

[0001] This invention relates to the field of power strip technology, specifically a highly protective safety power strip. Background Technology

[0002] A power strip, also known as a power strip or extension cord, is a multi-socket outlet with a power cord and plug that can be moved around. It can connect more than one power plug, saving both space and wiring. Power strips are generally made of materials such as bakelite, ceramic, and plastic. The main components of a power strip are: socket heads (socket head standards vary from country to country), power cords of different lengths (generally not shorter than 1.5 meters), copper wire cores, and the cross-sectional area of ​​the wire depends on the number of sockets (the more sockets, the thicker the wire). The amperage rating of the fuse is also directly proportional to the number of sockets.

[0003] The emergence of power strips has brought many conveniences to people's daily electricity use. However, when power strips are not in use, the sockets are open, exposing the copper plates inside. This makes it easy for water, dust, and iron objects to get into the sockets. Children can also easily stick their fingers into the sockets, thus posing a risk of electric shock or short circuit, greatly reducing the safety performance of the power strip. In order to address the above shortcomings, this invention provides a highly protective safety power strip. Summary of the Invention

[0015] (III) Beneficial Effects

[0016] This invention provides a highly protective safety power strip. It has the following beneficial effects:

[0017] (1) This highly protective safety power strip has a three-hole socket fixedly connected to the top of the bottom shell and inside the top shell, and a two-hole socket fixedly connected to the top of the bottom shell and behind the three-hole socket. The top of the three-hole socket and the two-hole socket are respectively provided with a first chamber and a second chamber. The first chamber and the second chamber are each provided with a protective mechanism, which includes a slider. The bottom of the inner wall of the first chamber and the second chamber are fixedly connected with short columns. The bottom of the inner wall of the first chamber and the second chamber are fixedly connected with fixed columns on both sides of the surface of the short columns. The inside of the slider is slidably connected to the surface of the fixed columns. The bottom of the slider is provided with a movable groove that matches the short columns. A buffer spring is fixedly connected between the top of the inner wall of the movable groove and the top of the short columns. The front of the top of the top shell is provided with a first socket. The top of the upper shell has a second socket on the back. The top of the slider and inside the first chamber are fixedly connected to a first baffle that matches the first socket. The top of the slider and inside the second chamber are fixedly connected to a second baffle that matches the second socket. By sliding the slider, the first and second baffles are moved to block the first and second sockets, preventing water, dust, and other debris from entering the power strip through the first and second sockets. It also prevents children from inserting their hands or sticks into the sockets out of curiosity. At the same time, it can effectively isolate the three chambers of live wire, neutral wire, and ground wire. Even if water enters, they will not be interconnected, ensuring a relative isolation between the three.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-5 This invention provides a technical solution: a highly protective safety power strip. A slider 71 moves to move a first baffle 76 and a second baffle 77 to block the first socket 8 and the second socket 9, preventing water, dust, and other debris from entering the power strip through these holes. It also prevents children from inserting their hands or sticks into the sockets out of curiosity. Simultaneously, it effectively isolates the live wire, neutral wire, and ground wire chambers, ensuring they remain relatively isolated even if water enters. This combination significantly improves the power strip's safety performance, eliminating the risk of electric shock and short circuits. The power strip includes a bottom shell 1 and an upper shell 2 fixedly connected to the top of the bottom shell 1. A three-hole socket 3 is fixedly connected to the top of the bottom shell 1 and inside the upper shell 2. A two-hole socket 4 is fixedly connected to the top of the bottom shell 1 and behind the three-hole socket 3. The tops of the three-hole socket 3 and the two-hole socket 4 are respectively provided with a first chamber 5 and a second chamber 6. Both the first chamber 5 and the second chamber 6 are equipped with protective mechanisms 7.

[0028] The protective mechanism 7 includes a slider 71. Short columns 72 are fixedly connected to the bottom of the inner walls of the first chamber 5 and the second chamber 6. Fixed columns 73 are fixedly connected to the bottom of the inner walls of the first chamber 5 and the second chamber 6 on both sides of the surface of the short columns 72. The inside of the slider 71 is slidably connected to the surface of the fixed columns 73. The bottom of the slider 71 has a movable groove 74 that matches the short columns 72. A buffer spring 75 is fixedly connected between the top of the inner wall of the movable groove 74 and the top of the short column 72. The buffer spring 75 has good elastic buffering force. When the plug pins leave the first socket 8 or the second socket 9, the elastic force of the buffer spring 75 can lift the slider 71, thereby preventing children from inserting foreign objects into the sockets and causing electric shock hazards.

[0029] In this embodiment of the invention, a first insertion hole 8 is provided on the front side of the top of the upper shell 2, and a second insertion hole 9 is provided on the back side of the top of the upper shell 2.

[0030] In this embodiment of the invention, a first baffle 76 adapted to the first socket 8 is fixedly connected to the top of the slider 71 and inside the first chamber 5, and a second baffle 77 adapted to the second socket 9 is fixedly connected to the top of the slider 71 and inside the second chamber 6.

[0031] In this embodiment of the invention, a power cord connection port 10 is provided on one side of the upper shell 2, and a switch slot 11 is provided on one side of the top of the upper shell 2. The power cord inside the power cord connection port 10 is connected to an external power source to supply power to the power strip.

[0032] In this embodiment of the invention, mounting blocks 12 are fixedly connected to the surfaces of both the three-hole socket 3 and the two-hole socket 4.

[0033] In this embodiment of the invention, the mounting block 12 has a mounting hole 13 inside.

[0034] In this embodiment of the invention, the interior of the mounting hole 13 is fixedly connected to the bottom of the inner wall of the upper shell 2 by fastening screws, which facilitates a tight connection between the upper shell 2 and the mounting block 12 by fastening screws, thus providing protection for the top of the two-hole socket 4 and the three-hole socket 3.

[0035] In use, the power strip is connected to an external power source via the power cord inside the power cord connection port 10 to supply power. After pressing the switch inside the switch slot 11, the user inserts the plug into the first socket 8 or the second socket 9 to power on the device. During insertion into the first socket 8 or the second socket 9, the prongs on the plug abut against the slider 71. At this time, the slider 71 slides obliquely along the fixed post 73. This setting does not hinder the use of the plug. When the prongs on the plug leave the first socket 8 or the second socket 9, the buffering force of the buffer spring 75 on the short post 72 causes the slider 71 to rise along the surface of the fixed post 73, thereby causing the slider 71 inside the first chamber 5 to drive the first baffle 76 to the first... The socket 8 is blocked, and the slider 71 inside the second chamber 6 drives the second baffle 77 to block the second socket 9, so that the tops of the first baffle 76 and the second baffle 77 and the top of the upper shell 2 are on the same plane. At the same time, there are no gaps between the first socket 8 and the first baffle 76 and between the second baffle 77 and the second socket 9, preventing water, dust and other debris from entering the power strip through the first socket 8 and the second socket 9. Through the setting of the first chamber 5 and the second chamber 6, even if water enters one of the three chambers (live wire, neutral wire and ground wire), it will not flow into the other chambers, thus ensuring a relative isolation between the three. At the same time, it can also prevent children from inserting their hands or sticks into the sockets out of curiosity, greatly improving the safety of the power strip.

[0036] In this invention, a three-hole socket is fixedly connected to the top of the bottom shell and inside the top shell, and a two-hole socket is fixedly connected to the top of the bottom shell and behind the three-hole socket. The tops of the three-hole socket and the two-hole socket are respectively provided with a first chamber and a second chamber. Both the first and second chambers are equipped with protective mechanisms, including sliders. Short columns are fixedly connected to the bottom of the inner walls of both the first and second chambers. Fixed columns are fixedly connected to the bottom of the inner walls of both the first and second chambers and on both sides of the surface of the short columns. The inside of the slider is slidably connected to the surface of the fixed columns. A movable groove adapted to the short columns is provided at the bottom of the slider, and a buffer spring is fixedly connected between the top of the inner wall of the movable groove and the top of the short columns. A first insertion hole is provided on the front of the top of the top shell. The back of the power strip has a second socket. A first baffle, matching the first socket, is fixedly connected to the top of the slider and inside the first chamber. A second baffle, matching the second socket, is fixedly connected to the top of the slider and inside the second chamber. By sliding the slider, the first and second baffles block the first and second sockets, preventing water, dust, and other debris from entering the power strip through them. This also prevents children from inserting their hands or sticks into the sockets out of curiosity. Furthermore, it effectively isolates the live, neutral, and ground wires, ensuring they remain relatively isolated even if water enters. This combination of features significantly improves the power strip's safety performance, eliminating the risk of electric shock or short circuits.

[0037] Meanwhile, the mounting block has mounting holes inside, and the inside of the mounting holes is fixedly connected to the bottom of the inner wall of the upper shell by fastening screws. This allows the upper shell to be tightly connected to the mounting block by fastening screws, thus providing protection for the top of the two-hole socket and the three-hole socket.

[0038] Meanwhile, fixed posts are fixedly connected to the bottom of the inner walls of the first and second chambers, and to both sides of the surface of the short column. The inside of the slider is slidably connected to the surface of the fixed posts. The bottom of the slider has a movable groove that matches the short column, and a buffer spring is fixedly connected between the top of the inner wall of the movable groove and the top of the short column. The buffer spring has good elasticity and buffering force. When the plug pins leave the first or second socket, the spring force of the buffer spring can lift the slider, thereby preventing children from inserting foreign objects into the sockets and causing electric shock hazards.
