#我来唠家常#
I don't know if you've noticed
No matter where the bus is
There will be a "small hole" in the seat
About the usefulness of this little hole
There are many opinions on the Internet
But most of them are not very reliable
As the old saying goes
"Existence is reasonable"
Let's explore it today
What's the use of this little hole?
01
Avoid damage to the seat
Extend the life of the seat
The average daily ridership of a bus
From a few hundred to thousands
Busier lines
Almost all day "full"
Such a high frequency of use
The leather is durable and not easy to break
It must be the first factor to consider
Everybody knows
For cost reasons
Bus seats
Most of them are made of plastic
Plastic stuff
The strength is more than enough, and the toughness is insufficient
It has been used for many years
It is inevitable to face some "big weight players"
If there is no such small hole
When there is a relatively large pressure shock
The seat may suddenly be "untenable"
And this little hole was opened
In the face of pressure shocks
The pressure can be distributed more evenly
The toughness of the seat will also be better
There will be no "cracking".
02
Cleaning is more convenient
There are also a few buses
Fabric seats are used
It's been used for a long time
It is inevitable that the following questions will arise -
And plastic seats + a small hole
It can perfectly solve the cleaning problem
The staff can rinse directly with a water gun
Cleaning is better
The efficiency has also been greatly improved
Because of the presence of small holes
It can be quickly hydrophobic and air-drying
It does not affect the use at all
03
Ventilation and cooling are more comfortable
Plastic does not have good heat dissipation
And the buses are basically with large windows
So in the summer
This is often the case with the following –
In this case
Keep a small hole in the seat
It's very necessary
Although it's just a small hole
However, it can increase the flow of airflow
The heat dissipation effect is instantly improved
Let passengers in the hot summer months
can have a better riding experience
Other than that
If you want to emit something
Special gases
The experience will also be a little smoother
(Just kidding)
04
It is more convenient to produce and transport
Multiple small holes in the seats
In the production of seats
The advantages can already be reflected
Plastic seats
Basically, a specific mold is used
Directly "pressed" out
Multiple small holes in the seats
Whether it is production or transportation
More convenient and efficient
Sum up
This little hole in the bus seat
It's really a lot of wisdom
In fact
A variety of items in everyday life
That's why it's designed to look like that
All of them have their own necessity
For example
The subway is also a means of public transportation
The seats are all like this
The light can see people, and it is not slippery
First of all
Same as bus seats
It is also for the purpose of convenient cleaning
We won't expand on that
secondly
Choose stainless steel, fiberglass
Smooth material
It's also for security reasons
The subway is underground
Confined spaces
Once there is a fire point
The diffusion rate is very fast
Stainless steel, fiberglass, these
Non-flammable materials
It can prevent the rapid development of open flames
Dramatically improved security
All right
That's all for today
Finally, a reminder for those who have children at home
Small holes in the bus seats
Don't mess around if it's okay
Avoiding "Happiness and Sorrow"
Doctor for a minute, his posture rising
I'm Dr. Curious
Nice to meet you
