Description
Technical field
The utility model relates to the instrument of launching, and relates in particular to a kind of portable strong crossbow.
Background technology
Bow and crossbow have used as a kind of weapon very early in China.Crossbow is to create on the basis of bow, owing to be subjected to the restriction of muscle power, the people draws back bow can not be lasting, in order to prolong the time that draws a bow, aiming better, our ancestors' utility model crossbow.Crossbow mainly is made up of bow and crossbow arm two parts, and the dress string is adorned the trigger mechanism of a crossbow on the bow on the arm, and both cooperate and shoot arrows.The use of crossbow is string to be drawn back to be buckled on the trigger mechanism of a crossbow earlier, waits to capture best emission during opportunity, moves " outstanding cutter " (trigger), shoots the arrow from the bow.The trigger mechanism of a crossbow has the earliest just played " time-delay mechanism ", and through updating, the performance of crossbow is become better and better later on, and kind is more and more.Though now crossbow is not used further to weapon, still doted on by fan and collector as a kind of ancient shooting apparatus, therefore it is studied improvement also in continuing to carry out.Though the structural change of crossbow, innovations in pattern or design determines the ejection mechanism of its key property substantially to become, and namely all drives the crossbow bolt action with the elastic force that bends.The crossbow of prior art remains in following deficiency, at first be subjected to the limitation of tradition " bow " structure, long crossbow bolt boosting slideway can not be provided, the basic tension force in short-term of bow that relies on promotes crossbow bolt, its thrust is restricted, namely can not make crossbow bolt obtain enough impulse forces, range is not good, and the short crossbow bolt that also is unfavorable for of slideway keeps stable at transmit direction in addition; Secondly, the general armrest arm of the crossbow of prior art is lifted the holder emission, and is inconvenient to aim at, and hit rate is lower; Again, rely on arm that string is drawn back and be buckled on the trigger mechanism of a crossbow, the operation effort, therefore can not bow do too strong, this has also limited the range of crossbow.
