Description

Flat rubber band mounting structure of catapult

Technical Field

The utility model belongs to the technical field of the catapult, especially, relate to a flat rubber band mounting structure of catapult.

Background

The slingshot is a tool which people like playing, people use the slingshot for entertainment, and the slingshot is also used for competition, so that playing methods of the slingshot are various. At present, the flat rubber band slingshot has two modes of installing a flat rubber band group, one mode is a binding type, and the other mode is a binding-free type. The binding type requires that the flat rubber band is bound and fixed on the bow body of the slingshot through the binding band. The first type is that a binding-free groove is pre-arranged on the bow body, the flat rubber band is pulled out after being rolled for several circles and then is plugged into the binding-free groove for fixing, or the flat rubber band is tightly pressed into the binding-free groove for fixing by a round rubber band with proper size; the second type is a screw locking type, and a pressing block is pressed on a rubber band groove of the bow body by using the rotating pressure of a screw, so that a flat rubber band placed in the rubber band groove is clamped tightly. However, the binding type and the first binding-free type are relatively complicated. The second type of binding-free type requires a special tool for disassembly and assembly, is also inconvenient and time-consuming.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The utility model aims at providing a flat rubber band mounting structure of catapult, it is simple structure not only, but also can realize the firm installation of flat rubber band.

(II) technical scheme

In order to achieve the above object, the utility model provides a following technical scheme: a slingshot flat rubber band mounting structure comprises a slingshot body, a flat rubber band, two clamping pins and two bowlegs arranged on the slingshot body, wherein a clamping groove is formed in the upper end of each bowleg, and the two ends of the flat rubber band are inserted into the clamping grooves after being folded respectively; two bayonet locks all are located outside pressing from both sides the groove, and insert respectively in the crack of the folding formation in flat rubber band both ends, the minimum width of bayonet lock cross section is greater than the width that presss from both sides the groove.

Through the technical scheme, the flat rubber band mounting structure is simple in structure, the pin lock is driven to tilt through the friction force of the flat rubber band and the pin lock in the stretching process of the flat rubber band, the pin lock is driven to compress the flat rubber band at the opening of one end of the clamping groove, and the flat rubber band is fixed with the bow arm.

In a further technical scheme, the cross section of bayonet lock is non-circular, and equal fixed mounting has the adapter sleeve on two bowarms, be equipped with the fastening groove in the adapter sleeve, the cross section of fastening groove is similar with the cross section of bayonet lock, bayonet lock and the flat rubber band of cladding in the bayonet lock outside are located the fastening groove.

Through above-mentioned technical scheme, because the cross section of bayonet lock is non-circular, causes flat rubber band to hug closely fastening inslot wall when the bayonet lock verts, the tensile force is big more tight that pastes to block flat rubber band, make flat rubber band fixed with the bow arm.

In a further technical scheme, the cross section of the clamping pin is triangular.

In a further technical scheme, fastening caps are sleeved on the two bow arms, are positioned at the lower ends of the fastening sleeves and are in threaded connection with openings at the lower ends of the fastening sleeves; the fastening sleeve is provided with an avoiding groove for extending the flat rubber band.

In a further technical scheme, a handle is fixedly installed on the bow body, and clamping grooves for installing the bow body are formed in two sides of the handle.

In a further technical scheme, the bow body and the bow arm are of an integrated structure.

(III) advantageous effects

Compared with the prior art, the technical scheme of the utility model have following advantage:

the flat rubber band mounting structure is simple in structure, and the flat rubber band drives the clamping pin to be tilted through the friction force between the flat rubber band and the clamping pin in the process of stretching the flat rubber band, and drives the clamping pin to tightly press the flat rubber band at the opening at one end of the clamping groove; in addition, because the cross section of bayonet lock is non-circular, causes flat rubber band to hug closely fastening inslot wall when the bayonet lock verts, the tensile force pastes more tightly more greatly to block flat rubber band, make flat rubber band and bow arm fixed.

Drawings

FIG. 1 is a three-dimensional structure of the present invention;

fig. 2 is an enlarged structural view at a in fig. 1.

Detailed Description

Example 1

Referring to fig. 1-2, a slingshot flat rubber band mounting structure includes a bow 1, a flat rubber band 2, two pins 3, and two bow arms 4 disposed on the bow 1, wherein the bow 1 and the two bow arms 4 are an integral structure. The upper end of each bow arm 4 is provided with a clamping groove 401, and the two ends of the flat rubber band 2 are respectively folded and inserted into the clamping grooves 401; the two clamping pins 3 are positioned outside the clamping groove 401 and are respectively inserted into a gap formed by folding two ends of the flat rubber band 2, and the minimum width of the cross section of each clamping pin 3 is larger than the width of the clamping groove 401. The bayonet 3 is non-circular in cross-section, preferably triangular here. All fixed mounting has adapter sleeve 5 on two bow arms 4, be equipped with the fastening groove in the adapter sleeve 5, the cross section of fastening groove is similar with the cross section of bayonet lock 3, bayonet lock 3 and the flat rubber band 2 of cladding in the 3 outsides of bayonet lock are located the fastening groove.

The two bow arms 4 are sleeved with fastening caps 6, and the fastening caps 6 are positioned at the lower ends of the fastening sleeves 5 and are in threaded connection with openings at the lower ends of the fastening sleeves 5; the fastening sleeve 5 is provided with an avoiding groove 501 for the flat rubber band 2 to extend out. The bow body 1 is fixedly provided with a handle 7, and the two sides of the handle 7 are provided with clamping grooves 701 for mounting the bow body 1.

The installation structure of the flat rubber band 2 is simple in structure, and the bayonet pin 3 is driven to tilt through the friction force between the flat rubber band 2 and the bayonet pin 3 in the stretching process of the flat rubber band 2, and the bayonet pin 3 is driven to tightly press the flat rubber band 2 at the opening at one end of the bayonet slot 701; in addition, because bayonet lock 3's cross section is non-circular, causes flat rubber band 2 to hug closely fastening inslot wall when bayonet lock 3 verts, the tensile force pastes more tightly more greatly to block flat rubber band 2, make flat rubber band 2 fixed with bow arm 4.

Example 2

This embodiment is the same as embodiment 1 except that the bayonet has a square cross-section.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
