Product Description

Plastic lockable pulley block

Product Introduction
1. The pulley structure frame is made of carbon steel plate; The hooks at both ends are welded at right angles to each other; The pulley is made of ABS engineering plastic; The main pulley is 40mm in diameter.

2. Matching of pulleys: Four single pulleys (including lockable); Two parallel pulleys; Two pulleys in two strings; Two strut pulleys.

Product Specification

Product name	Plastic lockable pulley block
Material	Plastic & mental
Size	---

Instructions
Carry out combination experiment according to the requirements of the teaching book.
When using the clamping pulley, pull the handle up to the top by hand to release the clamping stopper. At this time, wind the traction rope into the pulley groove, and pull the traction rope down to the bottom of the groove. Then move the handle downward to the bottom of the handle chute to fix the pulley and traction rope. When you want to pull the traction rope for experiment, you must first pull the handle upward to release the clamp stopper.
The fixed pulley experiment can be done with the support rod pulley and the experimental support.

Product feature and application
This plastic lockable pulley block can be used for grouping experiments of scientific physics in middle schools.
Understand the structure, working conditions and characteristics of various pulleys;
Measure the mechanical efficiency of pulley block;
It is used as an auxiliary instrument in other mechanical experiments.

Maintenance and precautions
1. Do not unscrew the screw behind the card head casually to prevent the loss of internal parts, which may cause the card to lose its positioning and stop function. In case of any failure of the connector during normal use, contact the manufacturer for repair.
2. It is found that several screws on the back of the frame are loose and can be tightened clockwise with a cross screwdriver.
3. Do not forcibly pull the traction rope when the clamping device is clamping the traction rope, or the brake clamp head will be worn, resulting in its failure.
4. In the experiment, the load of a single pulley shall not exceed 5N, and the load of double parallel or double string pulleys shall not exceed 10N. The frame shall be placed stably to prevent the falling of the hanging weight from injuring people.
5. When the instrument is not in use, it should be placed in a dry place to prevent oil contamination, high temperature and direct sunlight.
