Crossbow machine with automatic-winding motor and labor-saving launching mechanism

Abstract

The invention provides a crossbow machine with an automatic-winding motor and a labor-saving launching mechanism. The crossbow machine comprises a crossbow string, a crossbow body, a crossbow piece located at the front end of the crossbow body and an electronic switch controller, wherein a motor gear and rack mechanism and the labor-saving launching mechanism are integrated in the crossbow body, the motor gear and rack mechanism is connected with the electronic switch controller and comprises a gear box, and the motor, a first-stage speed reduction gear, a second-stage speed reduction gear, a string hooking gear, a string hooking rack and a ratchet wheel mechanism used for controlling movement positioning of the string hooking gear are arranged in the gear box, the motor is connected with the first-stage speed reduction gear, the first-stage speed reduction gear is meshed with the second-stage speed reduction gear, the top tooth surface of the second-stage speed reduction gear is meshed with the string hooking gear, the string hooking gear is meshed with the string hooking rack, and the string hooking gear is connected with both the crossbow string and a string hooking gear positioning ratchet wheel. By means of the crossbow machine with the automatic-winding motor and the labor-saving launching mechanism, an operator can save operation time and effort, the crossbow arrow launching frequency is improved, and unnecessary labor-saving devices for assisting manual winding, such as pedals and labor-saving pulley blocks, are reduced.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a crossbow with automatic winding by a motor and labor-saving launching mechanism. Background technique [0002] As an ancient cold weapon, the crossbow has the advantage of being charged and ready to attack, which can be launched after aiming. No additional force is required to control the string after it is strung, making it easier to operate than bows that require long periods of time to aim. With the development of weapons, crossbows as cold weapons were gradually replaced by hot weapons. However, in modern special operations and anti-terrorism operations, thermal weapons often have huge movements and are easy to cause the enemy to detect. As a weapon similar to thermal weapons, crossbows have the advantages of being close to silent, lethality close to modern thermal weapons, arrows of different materials and uses can be selected to meet different combat needs, and it is difficult for...

Problems solved by technology

However, the shortcomings of traditional crossbows are also very obvious. The manual winding method greatly affects the degree of automation of its operation, and manual winding will cause great inconvenience to the operator for long-term use.
