Problems solved by technology

The current compound bows are generally installed and debugged finished products, which are too large and inconvenient to carry; and drawing the bow requires artificially consistent draw distance and consistency of vertical and horizontal geometric relationships to achieve the purpose of shooting. The number of times a compound bow is used If there are too many, the bow limbs will be deformed to a certain extent, resulting in loose bow strings and reduced shooting accuracy. It needs to be sent to the manufacturer for repair or replacement parts, which is inconvenient and expensive to maintain

Abstract

The invention belongs to the technical field of archery equipment, and provides a folding composite bow which enables people to adjust the appropriate degree of tightness of a bowstring and to carry out routine maintenance. According to the technical scheme, the folding composite bow comprises a bow handle, bow pieces, handle piece connecting supports and a bowstring. The two handle piece connecting supports are installed at the two ends of the bow handle, one ends of the handle piece connecting supports are hinged to one side of the bow handle, end portions of the handle piece connecting supports horizontally extend to the other side of the bow handle, the other ends of the two handle piece connecting supports are fixedly connected with one end of a bow piece, the other ends of the two bow pieces are respectively provided with an eccentric wheel, the two eccentric wheels are provided with the bowstring, one ends, provided with the bow pieces, of the handle piece connecting supports are hinged to one end of a telescopic connecting device, the other end of the telescopic connecting device is hinged to a handle, and the telescopic connecting device is a small hydraulic oil cylinder or a small jack. The folding composite bow is used for outdoor archery and can be folded to be placed and carried.

Description

technical field [0001] The invention relates to a foldable compound bow, which belongs to the technical field of archery sports equipment, and in particular relates to a compound bow. Background technique [0002] Present compound bow mainly is made up of bow riser, bow limb, bow string etc. The current compound bows are generally installed and debugged finished products, which are too large and inconvenient to carry; and drawing the bow requires artificially consistent draw distance and consistency of vertical and horizontal geometric relationships to achieve the purpose of shooting. The number of times a compound bow is used If there are too many, the bow limbs will be deformed to a certain extent, resulting in loose bow strings and reduced shooting accuracy. It needs to be sent to the manufacturer for repair or replacement parts, which is inconvenient and expensive to maintain. Contents of the invention [0003] The present invention overcomes the deficiencies in the p...
