Abstract
A kind of light crossbow, comprises crossbow, crossbow body chord, and described crossbow is the torque spring that a pair tail end connects, be arranged on the front end of crossbow body, the middle part of described crossbow body is provided with draws string device and plucking device, and crossbow body is also provided with arrow groove, and described arrow groove is the groove to crossbow body front end in the middle part of crossbow body.The utility model adopts torque spring as the force storage device of crossbow, rapid operation, and structure is simple, is easy to carry, and distinctively draws string apparatus structure, simple to operate, easy to use.
Description
Technical field
The utility model relates to sports equipment and entertainment leisure area, is specially a kind of small-sized bow and crossbow.
Background technology
Bow and crossbow is a kind of traditional physical culture, leisure, article for hunting, is subject to some sports enthusiasts, outdoor enthusiast liked.Bow and crossbow according to type generally has bow and crossbow two kinds, and the advantage of bow uses flexibly, operation beautiful design, far firing range, but operation easier is higher, and the advantage of crossbow is that firing rate is fast, simple to operate, but structure is comparatively complicated.For small-sized light crossbow, its moulding is less to be easy to carry, and is subject to people's favor especially.
Present light crossbow, the general leaf spring that adopts, as bent body, utilizes the elastic deformation of leaf spring self to carry out storage of potential energy, for the injection of crossbow bolt provides energy.Although this can provide larger power for crossbow bolt, larger power is also needed to go to pull open bowstring, on the contrary for the quick shooting of light crossbow brings adverse influence.Meanwhile, adopt torque spring to carry out the principle of the power that stores, a long time ago just utilized by heavy crossbow, but the material that adopts by torque spring at that time limit, and could not miniaturization be realized.
Utility model content
The purpose of this utility model is to provide a kind of light crossbow easy to use.
For achieving the above object, the technical scheme that the utility model proposes is:
A kind of light crossbow, comprise crossbow, crossbow body chord, in the utility model, described crossbow is the torque spring that a pair tail end connects, be arranged on the front end of crossbow body, the middle part of described crossbow body is provided with draws string device and plucking device, and crossbow body is also provided with arrow groove, and described arrow groove is the groove to crossbow body front end in the middle part of crossbow body.
In the utility model, the both sides, front end of described crossbow body are provided with breach, and the body of described torque spring is arranged in breach.
In the utility model, described in draw string device to comprise to be fixed on crossbow extension string bolt with it and be slidably connected with crossbow body draw string hook, described in draw string hook string to be pulled to the position hanging string bolt, string is strained by extension string bolt.
Further, the described string hook that draws is included in the slide mass that crossbow slides and the triangle body being arranged on slide mass front end with it, described triangle body is isosceles triangular prism, the drift angle rib of isosceles triangular prism is connected on slide mass by rotating shaft, fitted with slide mass upper surface respectively by rotation around the shaft in two sides of isosceles triangular prism, string slot is preset in one of them side, prevents string slippage when pulled.
In the utility model, described plucking device is arranged on the rear hanging string bolt, utilizes lever principle to be pushed aside by the string hung on string bolt, string is rebounded original state, and crossbow bolt is penetrated.
In the utility model, the torque spring of described crossbow can be replaced the composite construction that torque spring that upper and lower two pairs of tail ends connect is arranged symmetrically with, or the composite construction of the torque spring arranged concentric of various outer diameter, while guarantee stable operation, accumulation of energy is larger, crossbow bolt firing rate is faster, and range is farther.
Compared with prior art, the utility model has the advantage of:
(1) by the force storage device of torque spring as crossbow, can store larger potential energy, the arm of force is longer simultaneously, rapid operation;
(2) overall structure is simply light, and dimensions range of choices is comparatively large, is easy to carry;
(3) distinctively draw string device, wind up simple to operate, crossbow bolt injection can not be affected again, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment.
Fig. 2 is the using state figure of the utility model preferred embodiment.
Fig. 3 is that the A of crossbow in Fig. 1 is to schematic diagram.
Fig. 4 draws the B of string hook to schematic diagram in Fig. 1.
In figure: crossbow 1, string 2, crossbow body 3, draw string hook 31, plucking device 32, arrow groove 33, hang string bolt 34, slide mass 311, triangle body 312, rotating shaft 313, string slot 314.
Detailed description of the invention
Below in conjunction with Figure of description and concrete preferred embodiment, the utility model is further described, but does not therefore limit protection domain of the present utility model.
See the light crossbow of Fig. 1-4, comprise crossbow 1, crossbow body 3 chord 2, described crossbow 3 is the torque spring that a pair tail end connects, be arranged on the front end of crossbow body 3, the middle part of described crossbow body 3 is provided with draws string device and plucking device 32, described draw string device to comprise to be fixed on the extension string bolt 34 on crossbow body 3 and be slidably connected with crossbow body 3 draw string hook 31, string hook 31 is drawn to be included in the slide mass 311 that crossbow body 3 slides and the triangle body 312 being arranged on slide mass 311 front end, described triangle body 312 is isosceles triangular prism, the drift angle rib of isosceles triangular prism is connected on slide mass 311 by rotating shaft 313, two sides of isosceles triangular prism by around the shaft 313 rotation fit with slide mass 311 upper surface respectively, string slot 314 is preset in one of them side, described crossbow body 3 is also provided with arrow groove 33.
The utility model in use, string 2 is hooked by drawing the string hook 31 that draws of string device, and in the string slot 314 that string 2 is fallen on triangle body 312, pull back and draw string hook 31, string 2 is hung over after on string bolt 34, crossbow bolt can be loaded in arrow groove 33, simultaneously slightly push-and-pull string hook 31 forward, and the triangle body 312 drawn on string hook 31 313 is rotated around the shaft, after string hook 31 then will be drawn to move extension string bolt 31 to, prevent it from hampering crossbow bolt injection; When needing crossbow bolt to penetrate, by pressing plucking device 32, the string 2 hung on string bolt 34 is held up by glass device 32, namely string 2 rebounds forward with crossbow bolt and is penetrated in arrow groove 33 by crossbow bolt.
