Abstract
A novel energy storage device of a crossbow is characterized in that a combined roller and a tension spring are fixedly mounted in a crossbow body respectively through a bolt pin; the combined roller is composed of two kinds of rollers which are different in diameter, wherein two large rollers and a small roller in the middle rotate synchronously; a bowstring for pushing an arrow is divided into two stands which are respectively enwound on the two large-diameter rollers of the combined roller; and a bowstring connected with the tension spring is enwound on the small-diameter roller of the combined roller. The utility model adopts the vertical crossbow body, so that the crossbow has simple and compact structure and good portability; and the combined roller and the tension spring are arranged in the crossbow body, so that the initial speed that the crossbow triggers the arrow is improved, and the operation is labor-saving.
Description
Technical field:
The utility model relates to a kind of new crossbow body, and the energy storage device of power and structural framing is provided in particular for crossbow.
Background technology:
At present, this ancient weapons of bow and crossbow not only become welcome amusement, physical culture and hunting apparatus, also as special police's special equipment, are with a wide range of applications.Modern crossbow is existing a lot of innovations in concrete structure and moulding, as patent 93105057.X, 99237136.8,02245366.0,200920091473.1 etc., but generally all be to be made of crossbow, crossbow arm, three parts of the trigger mechanism of a crossbow: the horizontal crossbow arm front end that is loaded on of crossbow, the trigger mechanism of a crossbow is installed on crossbow arm rear portion.The crossbow arm is in order to holding bow, support string, and for the user holding; The trigger mechanism of a crossbow is in order to button string, emission.Because crossbow roughly becomes cross-like with the crossbow arm, the lateral dimension of crossbow is bigger, therefore in actual use, the architectural feature that its width is bigger causes crossbow very inconvenience when jungle carries and use, and the crossbow body is caught on by plant and the gait of march that hinders the crossbow hand easily.Simultaneously, the power of doing to shoot with arculae also exists the shortcoming that operation is required great effort, fire effect is poor, product is single, service life is short.
The utility model content:
In order to solve existing crossbow carries inconvenience, operation effort, fire effect difference at jungle deficiency, the utility model provides a kind of energy storage device of novel crossbow, realized adopting the possibility of vertical crossbow body on the structure, make that crossbow is easy to carry in jungle, rapid operation, increased arrow simultaneously and propped up the initial velocity of percussion.
Technical solution adopted in the utility model is: with traditional T type crossbow structural reform is the vertical shape crossbow body that is integrated with the crossbow arm, is installed with combination roller and extension spring with bolt pin respectively in vertical crossbow body inside; The combination roller is made of two kinds of different rollers of diameter, two big rollers and a trundle that is positioned at the centre keep rotational synchronization, the string that promotes arrow is divided into two stocks and is not wrapped on two big footpath rollers that make up roller, and the string that connects extension spring is wrapped on the path roller of Combined pulley.Owing to replace the crossbow sheet as energy-accumulating medium with the high energy extension spring, and adopt the combination roller to change the resilience speed of crossbow string, improve the energy conversion efficiency of extension spring, increase arrow and prop up the initial velocity of percussion; Because crossbow no longer becomes cross-like with the crossbow arm, it is portable preferably to make crossbow have.
The beneficial effects of the utility model are, adopt that vertical shape crossbow body makes the compact conformation of crossbow simple, good portability; In the crossbow body, adopt combination roller and extension spring, improved the initial velocity when crossbow percussion arrow props up, and rapid operation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the cutaway view of combination roller
Fig. 3 is the vertical view of combination roller at crossbow body upper surface
Among the figure: 1. arrow props up; 2. vertical crossbow body; 3. combination roller; 4. string; 5. press the arrow sheet; 6. protecting cover; 7. trigger; 8. handle; 9. bolt; 10. extension spring; 11. extension spring casing; 12. extension spring connection cord; 13. retaining string piece; 14. stomidium; 15. returning spring; 16. bolt pin assembly.
The specific embodiment
As shown in Figure 1, the utility model structure is made up of vertical crossbow body 2, combination roller 3, string 4, extension spring connection cord 12, extension spring 10, spring casing 11, retaining string piece 13.Wherein, two retaining string pieces 13 are distributed on the crossbow body arrow road side by side, combination roller 3 is fixed on crossbow body 2 front ends by bolt pin assembly 16, extension spring 10 right-hand members as energy storage are fixed on the spring casing 11, the other end links to each other with connection cord 12, its medi-spring casing 11 and crossbow body 2 are fixed by screw, and not with its generation relative motion.
Shown in Fig. 2,3, combination roller 3 is made up of three parts, i.e. the angular speed that two major diameter rollers and a minor diameter roller that is positioned at the centre, three rollers sway is identical.The connection cord 12 that links to each other with extension spring 10 is wrapped on the path roller of combination roller 3, and the two ends of string 4 are wrapped in respectively on the rollers of two of roller 3 big footpaths of combination, and string 4 is put into gear on the string piece 13 simultaneously to stop the trend of shrinking forward that himself has.
Among the embodiment as shown in Figure 1, when needing the emission arrow to prop up, can earlier the string 4 between the retaining string piece 13 be pulled back above the bolt 9 that hangs over percussion lock.When string 4 spurred to the right, combination roller 3 turned clockwise, and extension spring connection cord 12 was wrapped on the path roller of combination roller 3, and connection cord 12 spurs extension spring 10 left simultaneously, made extension spring 10 savings elastic potential energys be in arm-to-arm.In this process, will pull the elastic potential energy that energy that string consumes is converted into extension spring 10 by combination roller 3 and extension spring 10, string 4 has movement tendency left under the effect of extension spring.During percussion, cocking 7, string 4 pulling bolts 9 are rotated counterclockwise, and string 4 props up 1 with bolt 9 disengagings with arrow subsequently and propels away, so far finishes a percussion process.
In the percussion process, owing to promote that arrow props up 1 string 4 and the connection cord 12 of pulling extension spring 10 is wrapped on the combination roller of synchronous rotation, different radii, and connection cord 12 is wrapped on the path roller, string 4 is wrapped on two big footpath rollers, so the tension force of string 4 is less than the pulling force of extension spring connection cord 12, and contraction rate forward is greater than extension spring connection cord 12 contraction rate backward, required arm strength but also increased the initial velocity that string 4 shrinks forward when so not only having reduced to draw string has improved the energy utilization efficiency of entire mechanism.
