Abstract
The utility model discloses a kind of Novel egg shell mould bow ocular structure catapult, comprise catapult main body and rubber band, two tops of described catapult main body Y type shelf are provided with the interspersed through hole with catapult main body lateral vertical, interspersed through hole is the different stepped hole in aperture, both sides, stepped hole transition position is provided with transition arc limit, rubber band two respectively socket joint in interspersed through hole and rubber band end is positioned at interspersed through hole macropore place, in the mouth of pipe of rubber band two, be respectively arranged with a hoodle, hoodle presses on the transition arc limit place in interspersed through hole.The utility model its adopt hoodle rubber band to be pressed on transition arc limit place, hoodle radian is identical with transition arc limit radian, and compressing contact position is that face contacts with face, relative to traditional linear contact lay, which reduces the degree of injury of rubber band.
Description
Technical field
The utility model relates to and launches technical field of tools, is specifically related to a kind of Novel egg shell mould bow ocular structure catapult.
Background technology
Catapult the most common launches class instrument as a kind of, always like by vast catapult fan, institute's moulding is simple, interesting extremely strong, and the crowd that can adapt to Different age group uses, catapult mainly comprises the rubber band that a shelf and two are individually fixed in catapult two jag ends, its fixed form of existing catapult mainly contains following several form: a kind of mode of to be the most common be also modal knotting setting fastening, another kind is that resistance is pullled in the form formation adopting card to insert, preferably the mode of bellmouth locking rubber band is adopted, the contact form of bellmouth and rubber band is linear contact lay, larger to the injury of rubber band, time one is long, rubber band usually there will be the phenomenon of extrusion fracture.
Utility model content
(1) technical problem that will solve
For solving the problem, the utility model proposes a kind of fixing fastening for above deficiency, contact surface is that the Novel egg shell mould that arc-shaped face contacts with face bends ocular structure catapult.
(2) technical scheme
Of the present utility modelly to be achieved through the following technical solutions: the utility model eggshell type bow ocular structure catapult, comprise catapult main body and rubber band, to be that Y type section bar is made form described catapult main body, two tops of described catapult main body Y type shelf are provided with the interspersed through hole with catapult main body lateral vertical, described interspersed through hole is the different stepped hole in aperture, both sides, described stepped hole transition position is provided with transition arc limit, to be that tubular rubber is made form described rubber band, described rubber band two respectively socket joint in interspersed through hole and rubber band end is positioned at interspersed through hole macropore place, a hoodle is respectively arranged with in the mouth of pipe of rubber band two, described hoodle presses on the transition arc limit place in interspersed through hole.
Improve as one, the radian on described transition arc limit is identical with hoodle radian.
Improve as one, described interspersed through hole side is provided with inlay card seam.
(3) beneficial effect
The utility model, relative to prior art, has following beneficial effect:
The utility model eggshell type bow ocular structure catapult shelf is provided with the different step-like interspersed through hole in aperture, both sides, transition position is provided with arc-shaped transition limit, adopt hoodle rubber band card to be pressed on arc-shaped transition limit place and fix rubber band, hoodle extruding rubber band is face contact, rubber band contact area is large, be subject to the degree of injury reducing rubber band in pulling force situation, avoid changing rubber band too continually, the fixed form of this kind of extruding can, when by making rubber band receive tighter and tighter when pulling force, make catapult bearing more firm simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model catapult shelf interts the sectional view of through hole.
Fig. 3 is the sectional view of interspersed through hole after the utility model is installed.
1-catapult main body; 2-rubber band; 3-hoodle; 11-interts through hole; 12-transition arc limit; 13-inlay card stitches.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
A kind of Novel egg shell mould bow ocular structure catapult as shown in Figure 1-Figure 3, comprise catapult main body 1 and rubber band 2, described catapult main body 1 forms for Y type section bar is made, two tops of described catapult main body 1Y type shelf are provided with the interspersed through hole 11 with catapult main body 1 lateral vertical, described interspersed through hole 11 is the different stepped hole in aperture, both sides, described stepped hole transition position is provided with transition arc limit 12, described rubber band 2 forms for tubular rubber is made, described rubber band 2 two respectively socket joint in interspersed through hole 11 and rubber band 2 end is positioned at interspersed through hole 11 macropore place, a hoodle 3 is respectively arranged with in the mouth of pipe of rubber band 2 two, described hoodle 3 presses on transition arc limit 12 place in interspersed through hole 11.
Wherein, the radian on described transition arc limit 12 is identical with hoodle 3 radian; Described interspersed through hole 11 side is provided with inlay card seam 13.
Be illustrated in figure 3 catapult eggshell type bow ocular structure cross sectional view, when installing and using, the hoodle 3 of predetermined coupling is embedded in rubber band 2 tubulus, rubber band head is pinched and middle part makes its extension that stretches with hand, being embedded from inlay card seam by the rubber band 2 after extending that stretches interts in through hole 11, firmly pull rubber band 2, treat hoodle 3 even at the cost of one's life in transition arc limit 12 place, namely installation process is completed, hoodle 3 in interspersed through hole 11 to rubber band 2 in squeezed state, catapult in use, rubber band 2 presents power of pullling backward and drives hoodle 3 to extrude rubber band 2, this process rubber band 2 will draw tighter and tighter, be conducive to catapult to use, intert through hole 11 in eggshell type simultaneously, during tension, hoodle 2 contacts with face with rubber band 2 and transition arc limit (12) face, reduce the degree of injury of rubber band 2.
Embodiment recited above is only be described preferred embodiment of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that this area ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
