Problems solved by technology

This has caused the difficulty of winding the bow. In order to overcome this phenomenon, people have done a lot of work, such as the recurve design of the bow body, the pulley bow, the pulley crossbow, the stringing device, etc., which increase the difficulty of manufacturing and the complexity of the structure.
At the same time, when the stored energy is released, due to the characteristics of the energy storage of the material, the initial release force is the largest, causing the string knocking phenomenon and affecting the ejection accuracy.

Embodiment Construction

[0015] exist figure 1 In the shown vacuum energy storage catapult, the piston 6 and the closed end of the barrel 4 form a vacuum chamber 7, and a valve 8 is provided at the end of the vacuum chamber 7 to exhaust the air. The fixed pulley 1 is installed on the open end of the cylinder body 4, the movable pulley 5 is installed on the piston 6, and the two ends of the string rope 3 are fixed to go around the movable pulley 5 and the fixed pulley 6 and hang on the string blocking body 2. The fixed pulley 1 has two, and the moving pulley block 5 has two to form a pulley system. The moving pulley 5 has changed the pulling force size and the pulling distance of the string rope, and the fixed pulley 1 has changed the pulling direction of the string rope.

[0016] figure 2 yes figure 1 top view partial sectional view. During operation, push the piston 6 to move toward the closed end of the cylinder 4, the air in the vacuum chamber 7 is discharged through the valve 8, the volume of ...

Abstract

The invention provides a vacuum ejection device with an energy storage function. A capacity-variable vacuum chamber consisting of a barrel and a piston is used as an energy storage body, and the size of the capacity of the vacuum chamber is changed by the aid of a chord rope via a pulley system, so that mechanical energy is stored or released. The vacuum ejection device realizes a constant-force spring effect, constant-force input and output of energy storage and releasing of the ejection device are realized, chord feeding difficulty is reduced, and an object is ejected stably. Simultaneously, the stress condition of the chord rope is improved.

Description

technical field [0001] The invention relates to a new energy storage and ejection device, in particular, a variable-volume vacuum chamber composed of a cylinder body and a piston is used as an energy storage body, and the storage and release of mechanical energy is realized by changing the volume of the vacuum chamber through a pulley system by strings and ropes. A device for ejecting an object. [0002] Background technique [0003] At present, when people make bows, crossbows, slingshots and other equipment, the elastic energy storage materials used, such as bamboo, wood, composite materials, rubber composite products, metal to carbon composite boards, etc., generally conform to a general rule, that is, Hooke According to the law, the elastic deformation of a material is proportional to the force it bears. When these materials are directly used to make bows and crossbows and other equipment, a large force is required at the end of bow winding. This has caused the diffic...
