Description

TECHNICAL FIELD

[0001] The utility model relates to a recoil mechanism of bird repelling gun, and specifically relates to a recoil mechanism of bird repelling gun. BACKGROUND

[0002] The bird repelling gun is a device for dispersing bird flocks by launching blank cartridges or sound and light cartridges to produce explosion sound, and is widely used in airports, farmlands and other places. The cartridge chamber may be caused to leave the chamber due to mechanical failure or environmental factors (such as dampness and foreign matter blockage) during frequent loading and launching, and the hidden danger needs to be eliminated through the recoil operation.

[0003] In the existing recoil operation, the tool is simple, the method is single, the subjective factors of the operator are limited, and safety accidents such as chamber explosion are prone to occur, and the personal safety of the operator cannot be guaranteed.

[0004] A novel general high-integration artillery hydraulic recoil device (authorized publication number CN221349853U) is disclosed in Chinese patent, which can apply slow thrust to the left-chamber bullet to enable the bullet to safely exit the chamber, avoid the accident hidden danger caused by strong impact on the bullet, and ensure the safety of operation. It can also be applied to artillery chambers of different diameters, and has good universality.

[0005] The patent technology relies on the discrete adjustment mechanism of the segmented telescopic rod, and the length is locked through the insertion of the movable positioning block and the through hole. Although it can adapt to different caliber chambers, it has the core defect of insufficient clamping force: the telescopic rod adjustment only realizes position fixation, cannot apply radial pre-tightening force to the non-slip pad, and causes the clamping friction force to completely depend on the elastic deformation of the non-slip pad. At the same time, the discreteness of the through hole spacing limits the adjustment accuracy, and the operator often faces the dilemma of "loose" or "tight", and it is difficult to match the best clamping position. These design defects cause the existing device to frequently appear clamping failure, barrel deviation and even slipping phenomenon during the recoil process, which seriously threatens the safety and reliability of the operation.
