Ball valve

It contains a cylindrical or spherical valve body (as the shell of the fluid channel), with a ball with a through hole inside (core control component, the through hole matches the diameter of the pipe), the ball is connected with the external handle through the valve stem, and both ends of the valve body are equipped with Flange or threaded interface (used to connect the pipeline, there are sealing grooves or gasket marks at the interface). The handle is rod-shaped or butterfly-shaped, and the valve can be fully opened/fully closed by rotating 90 °. Some models may include limit devices (to ensure accurate rotation angle).

Realistic Axe

The wedge structure of metal forging is divided into sharp cutting edge (curved cutting edge, thin and sharp edge), heavy axe back (for percussion), and hole groove connecting axe handle (mortise or metal hoop fixing). The surface may have hammer marks, corners or brand logos (such as cast characters/patterns) left by forging.

Z-type cable car

Advantages of structural mechanics: The Z-shaped polyline structure is supported by segments to disperse the force, which saves more space than the linear type, while improving the overall stability, suitable for scenes requiring vertical or inclined lifting (such as small cargo transportation, space partition lifting). Industrial style aesthetics: the naked frame, neat broken lines and mechanical details (such as connectors and sliding rails) are integrated, presenting a coarse and delicate industrial retro style. The lines are simple but full of power, becoming the visual focus in the space.

German FK C 48 typewriter

It is a classic mechanical typewriter, produced by the famous German typewriter manufacturer HeinrichErnemann. Known for its rugged and precise mechanical design, it was ideal for mid-20th century office and home use. Using the classic "QWERTY" keyboard layout, the character keys are divided into three lines, in addition to the basic character keys, but also equipped with space, carriage return, line feed and move up and other function keys. The design pays attention to the user experience, and the typing method is hard typing, that is, letters or characters directly hit the roller, which belongs to the mechanical typing method. The metal body and fine craftsmanship made it very popular at the time.

Metabo vintage electric drill

Metabo is a German power tool manufacturer with a long history, founded in 1924. Its vintage electric drill was one of the brand's early products, embodying Metabo's strict requirements for tool quality and durability. Robust metal housing and precise mechanical design provide stable drilling performance. It is known for its high output torque and motor overload resistance.

Mainly divided into two categories of DC generators and AC generators. Performance parameters include rated power, rated voltage, rated frequency, etc., which determine the output capacity and scope of application of the generator. When using a generator, it is necessary to select the appropriate model according to actual needs and ensure its stable operation to provide reliable power supply.

Titanic anchor

An important part of this famous cruise ship, each anchor weighs a staggering 15 tons. Physically fixed the Titanic and became part of its history. The construction of the Titanic began on March 31, 1909, and was launched on May 31, 1911. It sank after hitting an iceberg during its maiden voyage in April 1912, killing more than 1500 people. It was not until 1985 that the sunken ship was discovered by humans. Its anchor and other debris lay quietly on the bottom of the Atlantic Ocean. It is a symbol of engineering technology in that era and witnessed a great tragedy in the history of human navigation.
