I. Product Overview

This is a simple mechanical pendulum clock principle model, which restores the core mechanical structure of the pendulum clock in an intuitive parts assembly form. Through hand-built and operated, the pendulum clock's "isochronism" timing principle is deeply analyzed, and it is suitable for scenes such as scientific education, popular science demonstrations, and manual exploration, making abstract physical knowledge "visible and tangible".

II. Core Value

(I) Principle Visualization

Break the book concept and split and present the core components of the pendulum clock escapement mechanism, gear transmission, pendulum swing, etc. After assembly, you can observe manually: pendulum swing → escapement fork releases gear → gear group linkage, clearly understand "how to measure time through mechanical motion", and turn the "simple harmonic motion" and "mechanical energy conversion" in the physics textbook into a dynamic demonstration.

(II) Immersive Learning

From scattered parts to complete models, personally experience the whole process of structural cognition → assembly practice → principle verification. In screwing screws and engaging gears, hands-on skills are strengthened; by observing the swing amplitude and gear speed changes, the law of "pendulum length affects the swing period" is independently derived, so that knowledge learning changes from "passive acceptance" to "active exploration".

(III) Multi-scenario adaptation

Classroom teaching aids: The "artifact" used by physics teachers to demonstrate the principle of pendulum clocks makes abstract knowledge concrete in an instant;

Popular science exhibits: In science and technology museums and community activities, attract young people to explore hands-on and ignite scientific interest;

Family experiments: Parents and children play together, parents accompany their children to disassemble and assemble, and talk about the "secret of time measurement" while playing.

III. Product Details

(I) Parts Design

Material: Use safe and environmentally friendly plastic, which is tough and easy to bite, avoiding the sharp hidden dangers of metal parts, and children can operate it more safely;

Color: Orange, red, blue, gray and other colors distinguish functional modules (pendulum/pallet fork/gear set/bracket), intuitively identify the structure, and reduce the difficulty of assembly;

Precision: The gear pitch and shaft hole size are accurate, easy to bite and insert, no violent assembly is required, and the model runs smoothly.

(II) Assembly Experience

Clear steps: The accompanying manual comes with a 3D disassembly diagram + step-by-step process, from bracket construction to gear linkage, every step has guidance;

Moderate difficulty: No professional tools are required, it can be completed with bare hands or a simple screwdriver. Senior elementary school students can challenge it independently and feel a sense of accomplishment!

(III) Operation demonstration

After assembly, lightly flick the pendulum to trigger:

The "tick-tock" linkage of the escapement: the pendulum swings left and right, driving the escapement fork to release/lock the gear, simulating the "escapement speed regulation" function of a real pendulum clock;

The gear set drives in an orderly manner: the large gear and the small gear mesh and rotate, demonstrating "mechanical energy transmission and speed change" and intuitively understanding "how to convert the pendulum swing into continuous timing".
