Adjustable mechanical arms are commonly used in offices, laboratories, studios and other locations to support objects at various angles and heights, such as lights, computer screens, laboratory instruments, microphones, etc.   The adjustable manipulator consists of a base member and two connecting rods connected through a pivot joint, which are held in place by friction in the joint. By using spring assisted balancing devices that compensate for most of the weight, the amount of friction required to keep the equipment in place is reduced.   The pivot is a connecting ring that can rotate around an axis set at the pivot...

In order to prevent accidents caused by excessive wear of the carbon brushes on the collector device of the slip ring brush holder of the wind turbine, a normally closed switch-type alarm unit is configured for each carbon brush, and these alarm units are connected in series to the alarm. In the prior art, the grounding brush is held on the structure using a coil spring pressure finger lever structure. In order to ensure sufficient pressure after the carbon brush is worn, the initial pressure of the spring has to be increased, which aggravates the wear of the carbon brush. However, in...

With the increasing attention of human beings to environmental issues in the process of social progress, green and low-carbon has become a popular new trend, and energy-saving and environmental protection technologies and products continue to emerge, which are affecting and changing our lives. Hand power generation is a green way of energy supply. The generator powered by the radio contains a constant torque spring motor. When tightening the spring, the spring is gradually wound onto the larger drum, and the mechanical energy obtained during winding is converted into potential energy and stored in the spring. When the spring is released, the...

Luggage compartments in the aircraft cabin are usually located above the heads of seated passengers. To ensure optimum headroom between luggage compartments on the one hand, and to facilitate loading on the other hand, aircraft luggage racks can be lowered from shell luggage compartments or trays in certain applications. When lowered, the front of the luggage compartment opens for loading. A luggage compartment with a lowered housing for an aircraft, wherein the lowered housing is connected to a pulley attached to a support structure of the aircraft by a cable. In order to lower the shell, when the rope lifts...

A draw-wire encoder, also known as a string potentiometer, pull wire position sensor, cable extension displacement sensor, or yo-yo potentiometer. It is a cable driven position or displacement sensor for linear position measurement and velocity using a flexible cable (wire) and a spring loaded spool.   The string pot or cable extension sensor is composed of four main components in the shell: 1. High strength stainless steel cable (rope or steel wire rope); 2. Equal diameter spool (drum); 3. Power spring with high torque and long service life; 4. Rotary potential precision sensor.   In the shell of the sensor, a soft high-strength stainless steel...

As the building access door of modern plant, the industrial door must be familiar to everyone. The industrial door has a variety of lifting door modes. It slides upward according to the track installed on the wall, which is fast and stable. At present, the industrial door mainly uses the torsion spring balance system to stabilize the industrial door in the process of operation, so that it can be opened quickly.   Principle of torsion spring balance system: torsion spring balance is the principle that the weight of the door body is balanced by the torsion torque of the torsion...

Transmission hoses and wires are necessary for automotive production and maintenance work, but they are time-consuming and labor-intensive to sort out after use. Another common problem is safety when handling them. This can cause serious injury if the operator is inexperienced. Bulky and unwieldy hoses are also an added risk, especially if they are too short for the job. This forces the operator to move into dangerous positions that can cause injury.   The hose reel now solves these problems by incorporating the maneuverability of the power spring, allowing the long hose to automatically retract after use and align itself continuously and...

 Small engines are well known and are commonly used in lawn mowers and garden tractors and various other garden and lawn maintenance tools, in addition to other environments. Typically, each of these engines is equipped with a recoil starting system that includes a rope that rotates the starting mechanism to engage a flywheel that is connected to the engine for starting purposes. Once the rope starter is pulled, the recoil mechanism is always provided with the engine to reel the starter rope back to the starting mechanism.   The recoil portion of the starter mechanism is operated by a power...
