Details often determine success or failure. I remember that during a program interview, the host picked up a bottle of mineral water and asked Zong Qing how many teeth were on the cap. Zong Qinghou replied without hesitation: "General plastic bottles are 18 teeth." The host some hesitation, count the number, it really is 18. He did not expect that when a leader of a large company actually knew such a small problem. The same is true of decoration, and many important things are hidden in the details. For example, the height of the doorknob that will be mentioned next, the effect of reasonable and unreasonable design will be very different, and even affect your life. When installing the door handle height you need to consider the following points:
First, consider the height of the door handle, there is no child
Then we should consider whether there are children in the family. When a child is at home, he can't reach the doorknob. It is inconvenient when he uses it. This is also an important issue if the height of the doorknob is set too high. The child can't reach it. He will step on the chair to get there. This is a relatively big security risk. If you are afraid that it will be inconvenient to renovate later, you may consider setting a height of 100mm lower than the appropriate height for your family members. After all, your child will grow up, so you don't need to set it too low.
Second, the door handle height consideration height
The first is to consider the height of family members. When we install the doorknob, if there is no child at home, we can consider the average height of the family, then the height of the door handle is more suitable, then the height is about 1000mm; but if there is a child at home Then, we must consider setting the height of the doorknob between 800--850mm. If the doorknob is too high, the children in the family will have to step on the stool to be able to obtain it. This will pose a security risk.
Third, the height of the door handle consider the height of the elbow
To find the best height, the next step is to determine the height of the elbow. Because the door is not tailor-made for everyone, so just understand the body's approximate elbow joint position, and this height to make more people use comfortable to achieve the purpose, as long as the standard height of the elbow joint to understand where, It is possible to calculate the approximate height of the elbow based on each person's height and calculate the approximate height of the doorknob.
Fourth, the door handle height considerations open the door
The second is to determine what kind of position the family member opens. If I am decorating the doorknob, I think it should be the most comfortable for the level of the forearm, because the forearm and wrist joints are only subjected to pulling force, and there is no additional force for bending and twisting, which is mechanically the most economical. If I say that the door opening method is more popular, then the most suitable height of the door handle is probably the height of the elbow joint.
However, if other family members find it difficult to do so, other methods should be considered. If it is the door handle of the company or the hotel, a questionnaire survey can be conducted to investigate how people can open the door. The door handles that are so renovated are more popular and acceptable to people.
Decoration construction knowledge
1.cylindrical milling cutter
Used for processing flat surfaces on horizontal milling machines. Cutter teeth are distributed on the circumference of the milling cutter, and are divided into straight teeth and spiral teeth according to tooth shape. According to the number of teeth and coarse teeth and two kinds of fine teeth. The helical tooth rough tooth milling cutter has fewer teeth, high tooth strength and large chip space, which is suitable for rough machining. Fine-tooth milling cutters are suitable for finishing.
2. face milling cutter
Also known as disc milling cutter, used for vertical milling machine, end milling machine or gantry milling machine processing plane, end face and circumference have cutter teeth, also have coarse teeth and fine teeth. The structure has three kinds: integral type, insert type and transferable type.
3. End milling cutter
Used for processing grooves and step surface, knife teeth in the circumference and end face, can not work along the axial feed. When the end mill has end teeth through the center, axial feed can be provided.
4. Three-side edge milling cutter
Used for processing all kinds of grooves and steps, its two sides and circumference are provided with cutter teeth.
5. Angle milling cutter
For milling grooves at a certain Angle, there are two kinds of single Angle and double Angle milling cutters.
6.Saw Blade milling cutter
Used for machining deep grooves and cutting off workpieces, there are more cutter teeth on the circumference. In order to reduce the friction during milling, there are 15 '~1° auxiliary Angle on both sides of the cutter teeth. In addition, there are keyway milling cutters, dovetail slot milling cutters, T - shaped slot milling cutters and various forms of milling cutters.
