What is the principle of hand crank for lifting clothes rack? How to lock yourself? Find the internal structure diagram.

Principle: Manual operation pulls the steel wire to drive the clothes drying rod to pass through the corner and the top seat to make it rise or fall. The hand crank has self-locking function (mainly through the tightening or expansion of the built-in spring to generate friction), which can automatically lock the clothes drying rod at any height. When the hanger stops, it will automatically lock itself.

The internal structure diagram is as follows:

Extended data:

1, hand crank: This is the core component and power source of the clothes hanger. Shake the handle to drive the drying rod of the clothes rack to rise and fall. Light vibration and reliable self-locking are required.

2. Corner device: the intermediate device when the lifting rope changes direction, which requires the pulley to rotate flexibly after long-term use, so that the rope does not jump off the boat.

3. Top device assembly: It consists of two parts-top bracket and top cover. The top bracket plays a functional role, and the top cover plays a decorative role. The top bracket is firmly installed, which will not fall off and rust for a long time, and the pulley rotates flexibly, so that it will not jam or jump off the boat; The top cover should not rust, peel off, fade or lose leg color for a long time.

4. clothesline: this is a part that needs to pay attention to appearance very much. Clothes hang in this part, which is very eye-catching. Therefore, it requires sufficient rigidity (that is, it will not bend) and good surface treatment. Most clothes hangers are made of aluminum alloy.

5. Hanging rope: this is an important part connecting the crank and the hanger rod, and it requires no rust, no twisted wire and no hardness. Generally, 7*7 metal rope with the diameter of 1.2~ 1.8mm is used (galvanized iron wire is used at the earliest, mostly fake stainless steel wire rope, and standard stainless steel is rarely used).

6. Hanging ball: The connection between the hanging rope and the clothesline should be convenient, reliable and at least beautiful. Generally made of aluminum alloy.

7, pipe sleeve: because the hanger rod is hollow, the end is not good-looking, so there must be an end cover. The size is required to be appropriate and not easy to fall off.

8. clothes rack: it is a small clothes rack hanging on the clothes rail. Generally, a set of clothes hangers is equipped with 12~ 18, most of which are plastic, and a few high-grade clothes hangers are made of aluminum alloy.
