Description

The folding catapult

Technical field

The utility model relates to and launches the sports field of tool, particularly a kind of folding catapult.

Background technology

Catapult has a long history and certain civil foundation, is suitable for any crowd, is subjected to liking of men and women, old and young deeply, and on the history of its utilization, catapult not only can be hunted food, can also be in order to defend oneself the shooting enemy.In the modern times, catapult also is one of indispensable instrument of wilderness lore.General catapult is the skewer that is " Y " shape, and the elastic rubber band adhesive tape is connected in two ends of catapult frame, and its using method is to hold the catapult frame with one, and the another hand pinches rubber band bullet pocket backward directions and draws, the release hoodle that gets loose then, directive target object.But this catapult is not easy to carry because the bodily form is bigger, even carry reluctantly, also can cause very inconvenient burden.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of portable folding catapult.

The technical solution of the utility model is as follows:

A kind of folding catapult, comprise left catapult arm (1), right catapult arm (2) and box handle (3), the installation end of described left catapult arm (1) is connected by the left part of left rotary shaft (4) with box handle (3) upper end, and the installation end of described right catapult arm (2) is connected by the right part of right spindle (5) with box handle (3) upper end; When catapult folded, left catapult arm (1) and right catapult arm (2) were placed side by side in the cavity of box handle (3); When catapult launched, left catapult arm (1) and right catapult arm (2) formed " U " shape; Be provided with location pintle hook lock (6) spacing when left and right catapult arm launched above left and right rotating shaft, this location pintle hook lock (6) is positioned at box handle (3), and fixes by pintle hook lock pin (7) and box handle (3).

Adopt above structure, left catapult arm and right catapult arm are connected the corresponding end of box handle respectively by left rotary shaft and right spindle, are provided with location pintle hook lock spacing when left and right catapult arm launched above left and right rotating shaft.When catapult launched, left catapult arm and right catapult arm be by the location spacing formation of pintle hook lock " U " shape structure, and form the catapult structure of " Y " shape with box handle, for use; When catapult was folding, left catapult arm and right catapult arm overturn downwards around left and right rotating shaft, and be placed side by side in the cavity of box handle, dwindled the volume of catapult self like this, is convenient to carry.

As preferably, described box handle (3) is made up of shape size identical pull end plate (8) and back handle plate (9), pull end plate (8) is parallel to each other with back handle plate (9), all connect by steady pin (11) between both middle parts and between the lower end, two steady pins (11) and pintle hook lock pin (7) are all on the vertical center line of box handle (3).Adopt above structure, utilize the little characteristics in steady pin fixed interval (FI), be difficult for producing loosening between pull end plate and the back handle plate, make the gap of contact site of left and right catapult arm and forward and backward handle plate can not become big, the bow arm can not produce in front and rear direction and rock, and can guarantee the degree of accuracy of shooting.

As preferably, be provided with " L " shape opening in the left side of described pull end plate (8) and the right side of back handle plate (9), be somebody's turn to do the crosspiece of " L " shape opening above perpendicular section, and " L " shape opening is positioned at the below of left and right rotating shaft; Described pull end plate (8) and back handle plate (9) form flexible block (10) at the outer panel face of " L " shape opening part correspondence position, when left catapult arm (1) and right catapult arm (2) expansion, the lower surface butt of the upper surface of described flexible block (10) and respective side catapult arm.Adopt above structure, the lower surface of described flexible block butt catapult arm can prevent that the situation of upset downwards when left and right catapult arm launches from taking place, and plays support, spacing effect.

As preferably, described pull end plate (8) and back handle plate (9) are made by elastomeric material.Adopt this programme, at pull end plate and back handle plate the formed flexible block of " L " opening is set, under the effect of elastomeric material, produce the structure of staggered floor with the plane of forward and backward handle plate, when the bow arm launches, can butt the lower end of bow arm support with spacing, when the gathering of bow arm is folding, can bend arm plate face by butt, the bow arm is positioned in the empty van handle, avoid the bow arm from the empty van handle, to get loose and flipped out, improved the security of carrying.

As preferably, described location pintle hook lock (6) is up arc of arc top, have the spacing groove that connects its left and right sides end face in the lower end of location pintle hook lock (6), the bottom land wall of this spacing groove is last, and the bottom land wall of spacing groove by about two sections symmetrically arranged cambered surfaces form, each section cambered surface when catapult launches and the relevant position butt of respective side catapult arm spacing.Adopt above structure, in the pintle hook lock of location the arc surface of spacing groove when catapult launches and the relevant position butt of respective side catapult arm spacing, reduced the bow arm in the gap that upper and lower makes progress, bow arm deployed condition is more stable, also can guarantee the accuracy of shooting simultaneously.

Because left and right bow arm expansion radius is bigger, each parts causes interference during for fear of expansion, reaches the best expanded position when using, and the two ends of described spacing groove preferably are set to " V " shape groove.

Beneficial effect: the utility model compact conformation, easy to use, to be convenient to carry, the gap is little between each parts, and the expansion of bow arm and locking are more stable, fire accuracy height, the service life of having improved catapult.
