Problems solved by technology
[0002] At present, similar projectile devices at home and abroad are mainly pneumatic and gunpowder explosion. Pneumatic projectile devices have complex structures and high costs, and other auxiliary equipment (such as air compressors, high-pressure inflatable gas cylinders, etc.) must be used when using them.
However, the gunpowder explosive projectile device has large volume, strong recoil force, loud sound and poor safety in use.

Embodiment Construction
[0032] Such as figure 1 , 2 The shown embodiment of the mechanical ejector of the present invention includes a cylinder, a flexible disk 1 disposed in the cylinder, 18 strip-shaped elastic bodies 2, 18 fixed pulleys 3, and a fixed seat 7.
[0033] Cylindrical body is made up of front annulus 5, rear annulus 6, support bar 4 that is supported between anterior annulus and rear annulus (as image 3 shown). The front circular ring 5 and the rear circular ring 6 are formed by butt jointing of three 1 / 3 arc bodies respectively. There are three supporting rods 4, and each 1 / 3 arc body passes through the ends of the supporting rods 4 respectively, and is connected with a bolt assembly.
[0034] Each fixed pulley 3 is evenly distributed on the rear end of the front ring 5 along the circumference, and one end of each strip elastic body 2 is connected with the flexible disk 1 respectively, and the other end is connected with the front end of each fixed pulley 3 and the rear ring 6 res...

The invention relates to a mechanical catapult which comprises a cylindrical body, a flexible disk (1) that is arranged inside the cylindrical body, more than three strip elastic bodies (2) and more than three fixed pulleys (3); all the fixed pulleys (3) are distributed evenly at the front part of the cylindrical body along the circumference, one end of each strip elastic body (2) is respectively connected with the flexible disk (1), and the other end thereof is respectively connected with the back part of the cylindrical body by bypassing each fixed pulley (3); joint points between the strip elastic bodies (2) and the flexible disk (1) are distributed evenly at the margin of the flexible disk (1); the joint points between the strip elastic bodies (2) and the back part of the cylindrical body are distributed evenly at the back part of the cylindrical body. The mechanical catapult adopts the form of absolutely mechanical structure, takes the strip elastic bodies that are distributed evenly at the circumference as energy storing elements, and leads the strip elastic bodies to release instantaneously, thus shooting out objects at high speed. The mechanical catapult of the invention has simple structure, convenient processing and the advantages of convenient operation, large catapult distance, low catapult sound and little recoiling force, etc.
Description
technical field [0001] The invention relates to a projecting device for projecting objects, which is suitable for projecting props on a stage and projecting objects in fields such as fire fighting and rescue. Background technique [0002] At present, similar projectile devices at home and abroad are mainly pneumatic and gunpowder explosive. Pneumatic projectile devices are complex in structure and high in cost, and must have other auxiliary equipment (such as air compressors, high-pressure gas cylinders, etc.) when used. And gunpowder explosive type projectile device its volume is big, recoil force is strong, sound is big, use safety is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mechanical ejector, which does not need other auxiliary equipment when used, has low sound and good safety. [0004] The technical solution adopted by the present invention to solve the problems of the technologies described...
