Description

Spring coiling and retracting device

Technical Field

The utility model relates to a space flight equipment field, concretely relates to wind spring telescoping device.

Background

The coil spring is generally used as the power of a miniature machine without electric energy, such as the travel power of a mechanical clock and the power of a time telling system; the power of the disc rotation of the mechanical gramophone; a mechanical music box; an automatic player piano; power of the top string type toy, etc. The common point of machines powered by these types of spring is that the drive train is a speed-increasing mechanism, rather than a speed reducer as is commonly used in machines, and in addition, the torque output by the spring is large when it is tightened, but decreases considerably when it approaches full relaxation, and in order to reduce this uneven output torque of the spring, these devices have a speed-stabilizing mechanism which is used to stabilize the speed of rotation of the mechanism. In order to reduce the moment difference in the mechanical watch, a spring is specially made into an S shape in a free state instead of a plane equidistant spiral shape, so that the output moment of a coil spring is relatively balanced.

At present, chinese patent publication No. CN102699929A discloses a multi-leaf coil spring type linear extension mechanism, which comprises a base, a telescopic unit, a docking tray, and a power transmission unit; the telescopic unit is characterized in that the telescopic unit is provided with a zipper lock catch, the zipper lock catch is fixedly connected with the base, and the zipper lock catch is longitudinally provided with four coil spring piece converging grooves which are two groups of gradually-approaching structure slotted holes respectively; four coil springs are arranged corresponding to the four coil spring piece gathering grooves and respectively comprise an upper straight coil spring piece, a lower straight coil spring piece, a left arc-shaped coil spring piece and a right arc-shaped coil spring piece, the cross sections of the upper straight coil spring piece and the lower straight coil spring piece are integrally in a straight line shape and are provided with lock holes, the cross sections of the left arc-shaped coil spring piece and the right arc-shaped coil spring piece are integrally in an arc shape, and lock hooks are arranged at the edges of two sides of the left arc-shaped; the four rolling spring leaves are meshed into an I shape from the extending part of the zipper lock catch through the lock hole and the lock hook.

The multi-piece coil spring type linear extension mechanism is flexible, telescopic, reduced in mass and volume, increased in stroke, and more suitable for being used in the space weightless environment, but is short in extension distance and low in strength.
