Description
Technical Field
The utility model relates to a leather pocket and a rubber band for improving a slingshot (or a crossbow), in particular to a 3D integral leather pocket rubber band.
Background
At present, common rubber band leather pockets of slingshots and crossbows on the market are basically formed by manual cutting and binding, and the shapes, the sizes, the functions and the durability can not meet higher requirements.
Ordinary leather pocket rubber band is difficult to master by novice on the market, mainly embodies, and the shot is very difficult accurate places in the centre of leather pocket, even place in the centre of leather pocket, also produces the skew easily when the bow is drawn. The common leather pocket rubber band needs an operator to clamp a bullet in the leather pocket by fingers, when the rubber band is lengthened, the fingers are easy to rotate, so that the rear ends of the two rubber bands are not on the same plane, and a so-called 'rear hand spiral' generates a firing error. And the common rubber band realizes the connection of the rubber band and the rubber bag through binding, the work efficiency is very low, and the structure is unreliable. After the rubber band of the common leather pocket is launched, the rubber band is easy to wind and twist, and the arrangement is time-consuming and labor-consuming. The tail part of the common rubber band is smooth and is not easy to fix. The common rubber band is cut into isosceles trapezoids, so that when the common rubber band is stretched on a bow door, the two sides of a single rubber band are stressed unevenly, and the service life of the rubber band is short.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a 3D integral leather pocket rubber band, which greatly improves the manufacturing efficiency and firing precision of the leather pocket rubber band, learning easiness and user satisfaction.
The technical scheme of the utility model is as follows:
A3D integral leather pocket rubber band comprises a rubber band body and a leather pocket, wherein the leather pocket comprises a bowl-shaped magazine, and an axial pull buckle is connected to the tail part of the bowl-shaped magazine; two rubber bands are symmetrically arranged on two sides of the axis of the bowl-shaped magazine and connected to the bowl opening of the bowl-shaped magazine.
An aiming point is arranged on the outer edge of the bowl opening of the bowl-shaped magazine, and the distances from the aiming point to rubber bands on the two sides are the same.
The rubber band is provided with a twisting structure, and the cross section of the part of the rubber band twisted by 90 degrees is in a cross shape, a wave shape or an oval shape.
The rubber band is a strip-shaped rubber band, the wide edge of the connecting end of the strip-shaped rubber band and the slingshot body is set to be an inclined edge, and the acute angle between the inclined edge of the rubber band and the long edge is 5-30 degrees. The design can avoid the problem that the two sides of the rubber band are stressed unevenly when the bow is triangular.
The rubber band is folded in a free state (e.g., spiral or undulated, i.e., the rubber band is contracted in a free state).
A3D integral leather pocket rubber band comprises a rubber band body and a leather pocket, wherein the leather pocket comprises a bowl-shaped magazine, and an axial pull buckle is connected to the tail part of the bowl-shaped magazine; the front part of the bowl-shaped magazine is connected with a cylindrical rubber band with a coaxial line.
The utility model provides an integral skin pocket rubber band of 3D, includes rubber band, skin pocket, the skin pocket is for penetrating sword skin pocket, penetrates sword skin pocket structure and is thin square pole type or banding type or round bar type or ellipse shape type.
The utility model combines the axial pull buckle and the bowl-shaped bullet cabin together and is on the same axial line, thereby preventing the bullet from being not in the center of the leather pocket, preventing the bullet from deviating when the rubber band is stretched and preventing the two rubber bands from being not on the same plane due to the rotation of fingers after stretching. The launching point is ensured to be positioned on the central line of the trajectory, and the 'back hand helix' is avoided. Simultaneously with leather pocket rubber band integrated into one piece, effectively improve production efficiency, reduction in production cost, extension rubber band life-span, reinforcing rubber band degree of stabilizing improves the accuracy of percussion and the convenience of operation. The utility model greatly improves the satisfaction degree of user experience, has simple manufacture, low cost and accurate percussion and has better popularization prospect.

The missile launching system comprises a rubber band 1, an axial pull buckle 3, an aiming point 4, a bowl-shaped magazine 5, a torsion part 6, a bevel edge 7, a sword leather pocket 8 and a cylindrical rubber band 9.
Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
The bowl-shaped magazine 5 of the utility model triggers the shot, and the sword-shooting leather pocket 8 triggers the non-shot such as a short arrow.
Except that the cylindrical rubber band 9 is connected with the annular catapult body, the other rubber bands 1 are connected with the Y-shaped catapult body.
The bowl-shaped magazine 5 and the axial pull buckle 3 are made of elastic materials. The bullet and the bowl-shaped bullet cabin 5 are designed to be in transition fit or magnetic materials are distributed in the bowl-shaped bullet cabin 5, so that the bullet can be prevented from falling out.
The design that the axial pull buckle 3, the bowl-shaped bullet bin 5 and the cylindrical rubber band 9 are tightly combined together changes the defect that the cylindrical rubber band 9 is not centered when balls are placed in the prior art, and the direct pull buckle is not arranged, so that the rubber band is easy to break.
When the bullet storage box is used, a bullet is placed into the bowl-shaped bullet storage box 5, and the axial pull buckle 3 is pulled by fingers, so that the shot firing point is closer to the center trajectory of the rubber band 1 to coincide.
Example 1
As shown in fig. 6, one end of the rubber band 1 (belt shape) is connected with the bowl-shaped magazine 5 into a whole, and the tail part of the bowl-shaped magazine 5 is connected with an axial pull buckle 3; two rubber bands 1 are symmetrically arranged on two sides of the axial lead of the bowl-shaped magazine 5 and connected to the bowl opening of the bowl-shaped magazine. An aiming point 4 is arranged on the outer edge of the bowl opening of the bowl-shaped magazine 5, and the distances from the aiming point 4 to the rubber bands 1 on the two sides are the same. The other end of the rubber band 1 is arranged into a bevel edge 7 and is connected with the slingshot body, and the acute angle between the bevel edge 7 of the rubber band 1 and the long edge is 10 degrees; the belt-shaped rubber band 1 is vertically connected with the slingshot body, and the acute angle is arranged on the outer side. The rubber band 1 is arranged in a wavy shape.
Example 2
As shown in fig. 7, one end of the cylindrical rubber band 9 (purchased part) is connected with the bowl-shaped magazine 5 into a whole, and the tail part of the bowl-shaped magazine 5 is connected with an axial pull buckle 3; the other end of the cylindrical rubber band 9 is fixed on the annular catapult body.
Example 3
As shown in fig. 8, it is a non-projectile type such as a shooting arrow, and therefore, the structure of the shooting sword leather pocket 8 is designed into four forms of a thin square rod type, a strip type, a round rod type and an oval type, and both ends of the shooting sword leather pocket 8 are respectively connected to a rubber band (the rubber band is omitted in the figure).
The utility model greatly reduces the entry threshold and the training intensity of a novice and improves the accuracy and the efficiency of shooting games. The leather pocket and the rubber band consumable material in the percussion game are lower in manufacturing cost and higher in manufacturing efficiency, and have better popularization prospect.
