Description
Technical field
The present invention relates to the instrument of launching, particularly relate to a kind of Portable strong crossbow.
Background technology
Bow and crossbow employ as a kind of weapon very early in China.Crossbow creates out on the basis of bow, and owing to being subject to the restriction of muscle power, people pulls open bow can not be lasting, in order to extend the time drawn a bow, aims at better, and our ancestors have invented crossbow.Crossbow is primarily of bow and crossbow arm two parts composition, and bow fills string, arm fills the trigger mechanism of a crossbow, both coordinate and shoot arrows.The use of crossbow first string is pulled open to be buckled on the trigger mechanism of a crossbow, to be captured to best launching time time, move " outstanding cutter " (trigger), shoot the arrow from the bow.The trigger mechanism of a crossbow the earliest just plays the effect of " time-delay mechanism ", and later through updating, the performance of crossbow is become better and better, and kind gets more and more.Although now crossbow is not used further to weapon, as a kind of ancient shooting equipment still by fan and collector are doted on, therefore to its Improvement also in continuing to carry out.Although the structure change of crossbow, innovations in pattern or design, determines that the ejection mechanism of its key property does not become substantially, namely all drives crossbow bolt action with the elastic force of bow.The crossbow of prior art remains in following deficiency, first by the limitation of tradition " bow " structure, longer 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 crossbow bolt can not be made to obtain enough impulse forces, and range is not good, and slideway is shorter in addition is also unfavorable for that crossbow bolt keeps stable in a transmit direction; Secondly, the general armrest arm of crossbow of prior art is lifted holder and is launched, and is inconvenient to aim at, and hit rate is lower; Again, rely on arm string is pulled open to be buckled on the trigger mechanism of a crossbow, operation effort, therefore can not bow do too strong, which also limits the range of crossbow.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of novel Portable strong crossbow is provided.It can make crossbow emissivity stronger, and range is farther; Be convenient to aim at, shoot straight.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of Portable strong crossbow, comprise crossbow holder, crossbow frame, handle, cocking mechanism and ejection mechanism, it is characterized in that, described crossbow holder is fixedly connected with the rear end of described crossbow frame, described crossbow frame is provided with chute along direction of ejection, described handle is fixed on the bottom of described crossbow frame, and described cocking mechanism is located on the crossbow frame of described handle front portion;
Described ejection mechanism comprises symmetrically arranged left and right elastic plate and pantograph;
Described pantograph comprises cuts arm, rear pin shaft hole, front pin shaft hole and left and right foramen alare, described in cut arm and intersect the parallelogram sturcutre that constitutes by an active connection each other, described left and right foramen alare is respectively equipped with left and right elastic plate socket; Described pantograph is connected on described crossbow frame by rear pin shaft hole and rear pin shaft, front bearing pin is provided with in described front pin shaft hole, and be arranged in described chute by front bearing pin, the upper end of described front bearing pin is connected with and pushes away arrow block, when pantograph is retracted, the lower end of described front bearing pin locks with described cocking mechanism and is connected;
The rear end of described left and right elastic plate is fixed on the rear portion of described crossbow frame by frame clamp, front end is inserted in described left and right movable socket respectively.
The invention has the beneficial effects as follows: owing to have employed elastic plate structure, " bow " that can be more used than prior art obtains larger emissivity, owing to adopting scissors stretching structure, the stroke of elastic plate has been carried out abundant amplification, thus obtain longer transmitting slideway, crossbow bolt can be made like this to obtain the thrust continued, slideway obtains larger acceleration, to ensure that range is farther; Due to the good guide of slideway, also improve the hit rate of crossbow bolt simultaneously; This structure operationally similar rifle in addition, is punctured into one at non-working condition along crossbow frame, adds that braces can carry than general crossbow more convenient.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described elastic plate is made up of multilayer elastic steel plate.
Adopt the beneficial effect of above-mentioned further scheme to be can design according to purposes, select the steel plate layer array dress elastic plate of suitable dynamics.
