Get up at night and want to go to the toilet. I can't tell east, west, north and south in the dark. It's really troublesome to grope for the switch to turn on the light! Wouldn't it be easier to turn on the light if I got out of bed and put on slippers? So I had an inventive idea: put a high-energy and long-life button cell, a small light bulb and a microswitch on the sole of slippers. When the foot reaches into the shoe and steps on the ground, press the microswitch to connect the circuit, and the small light bulb lights up to illuminate the front.
When I got back to bed from the toilet and my feet left my slippers, the light went out. I also got into bed, and there was no trouble turning on and off the lights.
Invention: safety socket
Nowadays, household appliances are popular and there are many power plugs.
Some people don't pinch the plug when pulling the power plug, but pull the wire, causing damage to the plug wire and sometimes getting an electric shock.
My safety socket is designed for this problem.
As shown in the upper left, the socket panel has only two covered pinholes and a button flush with the panel.
The internal structure of the socket is shown in the left figure below. When the plug is inserted, the hole covers of two plastic movable pins are pressed into the hole wall, and the two elastic pins below are pressed. When the pins are in place, the upper two plastic movable pins are ejected, locking the pins (with grooves on the pins) to prevent them from sliding backwards. The copper ring on the pin just touches the electrode elastic copper ring on the hole wall, and the power supply is connected.
When you need to pull out the plug, press the button, and the two plastic movable pinhole covers will bounce back, and the needle will automatically pop up, disconnect the power supply and reset the button at the same time.
It can avoid the bad actions of pulling wires and unplugging plugs by hand, and can also prevent children from playing with sockets; It can also prevent the plug from loosening and falling off.
Invention: anti-theft screw
Traditional wooden screws are not safe to screw out.
I designed a new type of wood screw, improved the original nail head, and changed one side of the nail head into an inclined plane, which could not be screwed out after being screwed in. This was discovered by accident.
Once, I screwed a screw on the wood. Because the wood was too hard, the screwdriver scratched the nail head and I couldn't screw it in any more.
So, I thought of turning this scraped slope into an anti-theft wooden screw in turn.
Can be used in doorplates, wooden boxes, bus stop signs and other places, and can not be removed with general tools.
Invention: Earplugs can be used.
At present, earplugs can only be used by one person, and earplugs are needed in many cases.
For example, in a family of three, children do their homework at night, and parents should wear earplugs to watch TV programs so as not to affect their children.
At this time, only one person can enjoy earplugs.
Earplugs can solve this kind of problem well.
With this earplug, two or more people can enjoy TV, listen to music, surf the Internet and so on. Without affecting the people around you, as shown in the figure.
1 is the jack, 2 is the matcher, 3 is the volume and sound quality tuner, 4 is the earplug, 5 is the auxiliary earplug, and 6 is the plug.
* * * When in use, just insert the gamete earplug into the jack of the matcher.
The sound quality and volume can be adjusted at will.
This invention has applied for a national invention patent.
Nowadays, popular clothes hangers generally have no windproof function, and users often encounter such troubles: a newly washed dress hangs on a rope to dry, and when the wind blows, it falls to the ground and needs to be washed again.
The self-locking windbreaker hook I invented can relieve everyone's troubles.
The above picture is a schematic diagram of the self-locking windproof clothes hanger: in the above picture, (1) is a lock sleeve, (2) is a lock column, and a lever is formed by a rotating shaft (3) and a crank (4), and the lever rotates with (3) as a fulcrum under the action of a counterweight (5).
When hanging clothes, just lift the crank (4) by hand or hook. Under the action of gravity, the lock sleeve (1) and the lock column (2) are automatically separated. The user can hang the clothes hook on the rope smoothly and then loosen the crank. Under the action of the counterweight (5), the lock post (2) is automatically connected with the lock sleeve (1).
The process of taking off the clothes hanger is also very simple: just lift the crank (4) upward by hand or hook, the lock will automatically open, and the user can take off the clothes hanger conveniently. The self-locking windproof clothes rack can not only hang clothes on the rope to dry by hand, but also hang clothes or take off clothes easily if you want to hang clothes in a higher place.
At the same time, the clothes hanger also has the characteristics of simple manufacture, good reliability and low cost.
My little invention won the national invention patent.
Technological gizmo: convenient newspaper folder
In order to facilitate reading, sorting and collecting newspapers, the reading room of the library usually uses newspaper clips to clamp the first issue of newspapers together, and then takes them down and binds them one month later, which is not convenient.
The newspaper clip I designed can directly bind the newspaper through the binding hole with the binding line without taking off the binding line every time the newspaper is full.
Its structure is that three positioning holes are drilled in the ordinary newspaper clip, and a pointed positioning pile with holes is installed in each positioning hole.
When in use, the newspaper is placed on the positioning post every time, and the other newspaper folder is closed, so that the newspaper is fixed on the newspaper folder, and the newspaper is directly inserted into the hole for binding after being full.
This folder is most suitable for use in the library.
