Abstract
The utility model discloses an artillery firing toy for teaching children through lively activities, and relates to the field of toys for the children. According to the technical scheme, three to four supporting legs which make contact with the ground are arranged on a supporting frame, two cylindrical protrusions are arranged outside a gun barrel, the axes of the two protrusions coincide, the axes of the protrusions are located in the diameter direction of the gun barrel, the number of supporting rods is two, a through hole is formed in each supporting rod, the through holes of the two supporting rods are at the same height, a ball is fixed into each through hole, the protrusions on the two sides of the gun barrel penetrate through the balls of the two supporting rods respectively, then, the two supporting rods are fixed to the supporting frame, a circular rubber piece is fixed to the edge inside the cylindrical gun barrel, a pull rope suspension hole is formed in the center of the lower surface of the circular rubber piece, a pull rope is fixed to the pull rope suspension hole, and the movable end of the pull rope is provided with a finger ring. The artillery firing toy has the advantages that tensile deformation of the rubber piece is embodied so that the rubber piece can have elastic potential energy, the artillery firing toy can fly to the farthest place when fired at the 45-degree angle, the artillery firing toy is simple and easy to maintain, and the artillery firing toy is relatively safe due to the fact that small foam balls are used.
Description
Technical field
The present invention relates to toy for children field, particularly the toy of bead transmitting.
Background technology
Child is innately a beautiful plain pape, does not know anything; Child has curious sense to various fangles, particularly for firearms toy.For the transmitting of shell, the impacts such as the strength of being launched, the angle of transmitting, air drag, gravity, the flying distance of shell has larger difference; The air drag and the gravity that affect toy shell flight, air drag causes velocity attenuation, gravity causes shell to fall, decision be the time of flight.
Summary of the invention
When being at play for guiding child, can observe and understand some physical knowledges, promote follow-up study can grasp faster and better physical basis knowledge, the present invention designs a kind of shell shooting toy.
The technical scheme that the present invention realizes goal of the invention employing is: a kind of shell shooting toy, by bracing frame, support bar, gun barrel, rotating shaft and circular elastic sheet, formed, and it is characterized in that: bracing frame has the feet of 3-4 kiss the earth; There are two cylindrical protrusions in gun barrel outside, two protruding deads in line, and the axis of projection is positioned at the diametric(al) of gun barrel; Support bar has two, and each support bar has a through hole, and the through hole of two support bars is contour, fixes a ball in each through hole, and the projection of gun barrel both sides pierces into respectively the ball of two support bars, and then two support bars are fixed on bracing frame; A circular elastic sheet is fixed at the edge of cylindrical shape gun barrel inside, and there is a span wire suspension hole at the lower surface center of circular elastic sheet, and a bracing wire is fixed in span wire suspension hole, and the movable end of bracing wire has a finger loop.
Lead to the hole site at support bar has markings that become 45 degree with horizontal plane.Gun barrel is comprised of gun barrel top and gun barrel bottom, gun barrel top is a pipe, there is external screw thread, gun barrel bottom is a pipe, has internal thread, and the gun barrel top being in contact with one another and the mouth of pipe of gun barrel bottom extend in pipe, form a circular platform, berm width is 3-5mm, and circular elastic sheet is fixed between the platform of the inside bore that gun barrel top and gun barrel bottom be in contact with one another, and by screwing screw thread, fixes circular elastic sheet.Thicker than edge in the middle of circular elastic sheet, upper surface is that plane, lower surface are arcwall face, and there is a span wire suspension hole at arcwall face center.The internal diameter of gun barrel is 6-8cm, and the diameter of foam bead is than the little 3-4cm of gun barrel internal diameter.
The invention has the beneficial effects as follows: the physical knowledge that can embody has circular elastic sheet tensile deformation to have elastic potential energy kinetic energy when potential energy can change bead transmitting into; After bead outgoing, be subject to Action of Gravity Field, at the height of ignoring air drag and gun barrel mouth, 45 degree angle of departure flights farthest, of the present invention by pivoting, and changes the angle of departure, and have the markings of one 45 degree, and prompting in such angle of inclination transmitting farthest.This device is simple, safeguards easily, adopts foam bead, safer.

The specific embodiment
A shooting toy, is comprised of bracing frame 1, support bar 2, gun barrel 3, rotating shaft 5 and circular elastic sheet 4.Bracing frame 1 has the feet of 3-4 kiss the earth, because 3 determine a plane, three feets are minimum requirements, if ground out-of-flatness, four feet, also only have three feet kiss the earths, there is a feet unsettled, if but there is a feet to damage, remain three feets and equally can determine a plane, therefore there is amount of redundancy, can extend the service life of bracing frame 1.On bracing frame 1, fix two support bars 2, the support bar 2 on support bar 2, gun barrel 3 and the right side in left side is crossed in a rotating shaft 5 successively, namely the support bar 2 on support bar 2, gun barrel 3 and the right side in left side has the through hole of dead in line, there is screw thread one end of its shaft, the emerge outside of support bar of rotating shaft screw thread, employing nut is fixed, and gun barrel 3 is around rotating shaft rotation, support bar 2 with rotating shaft 5 intersection location, on support bar 2, have markings that become 45 degree with horizontal plane; Motion for ease of bracing wire, the axis of rotating shaft 5 departs from the diametric(al) of gun barrel slightly, or be improved to a diametric(al) at gun barrel, there are two projections in the outside of gun barrel 3, in the through hole of two support bars 2, each fixes a ball, the projection of both sides pierces into respectively the ball of two support bars 2, then support bar 2 is fixed on bracing frame 1.
During use, foam bead is lost into gun barrel top 11, pulls finger loop 7 and makes bracing wire 6 drive circular elastic sheet center 4 to move down, and circular elastic sheet 4, because there is deformation, has elastic potential energy, and hand is decontroled finger loop, and elastic potential energy impels foam bead to fly out from gun barrel.If ignore gun barrel to the height on ground, the angle of departure of 45 degree will be launched farthest, therefore on support bar 2, have the markings with horizontal direction inclination 45 degree.
