Abstract
The invention relates to a pair of telescopic nunchakus which comprises two sections staffs (1) connected by a chain (2). Each section of staff (1) is divided into three telescopic rods, including anexternal rod (11), a middle rod (12) and an internal rod (13); the chain (2) is connected in a piston block (3) in the internal rod (13); the external rods (11) of the two sections of staffs (1) are provided with matched connecting threads; the inner cavities of the external rod (11) and the middle rod (12) are both provided with inverted L shaped slots (4) which are matched with bulges on the external walls of internal rod (13) and the middle rod (13). The three telescopic rods of the telescopic nunchakus can be contracted into one, and the chain can be contracted in the internal rod completely; and two sections of staffs are connected into a whole by threads; therefore, the telescopic nunchakus has the advantages of small size, light weight, good telescopic nunchakus, and the like.
Description
Technical field
The present invention relates to a kind of athletic equipment, relate in particular to a kind of nunchakus.
Background technology
Now, nunchakus not only can be used as a kind of self-defence instrument and uses, and can be used for body-building, amusement or other recreation.Mainly there are following two big defectives in existing nunchakus:
1, volume big, carry inconvenience, be unfavorable for self-defence.
2, chain is in the retractable rod body, and is attractive in appearance inadequately.
Summary of the invention
Technical problem to be solved by this invention provides a kind of scalable nunchakus, to solve the defective of carrying inconvenience in the prior art.
Technical scheme
A kind of scalable nunchakus, the two joint rod bodies that connected by chain constitute, described rod body is divided into outer bar, intermediate bar, three expansion links of interior bar, in the piston block in chain is connected in the bar, on the outer bar of two joint rod bodies the connecting thread that matches is arranged, " Γ " shape groove is arranged in the inner chamber of described outer bar and intermediate bar, and the projection on this " Γ " shape groove and described interior bar and the intermediate bar outer wall matches.
Beneficial effect
Three expansion links of rod body of the present invention can be shrunk to one, and in chain can be fully retracted in the bar, and two rod body appropriate combination are integral, and have advantages such as volume is little, in light weight, easy to carry again.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is respectively the cutaway view and the outline schematic diagram of interior bar, intermediate bar, outer bar.
(1) be that interior bar (2) is outer bar for intermediate bar (3)
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in the figure, a kind of scalable nunchakus, the two joint rod bodies 1 that connected by chain 2 constitute, it is characterized in that: described rod body 1 is divided into outer bar 11, intermediate bar 12,13 3 expansion links of interior bar, in the piston block 3 in chain 2 is connected in the bar 13, on the outer bar 11 of two joint rod bodies 1 connecting thread that matches is arranged, " Γ " shape groove 4 is arranged in the inner chamber of described outer bar 11 and intermediate bar 12, the projection on this " Γ " shape groove 4 and described interior bar 12 and intermediate bar 13 outer walls matches.
The present invention realizes in the following manner: at first, turn on outer bar, drive by chain and pull out two expansion links, the projection of bar is slided in the internal channel of coupled outer bar relatively in making, after being pulled out to certain-length, axially rotation can not endwisely slip expansion link.After treating all to stretch out, structure and common nunchakus are basic identical.
Claims (1)
1. scalable nunchakus, the two joint rod bodies (1) that connected by chain (2) constitute, it is characterized in that: described rod body (1) is divided into outer bar (11), intermediate bar (12), (13) three expansion links of interior bar, chain (2) is connected in the piston block (3) in the interior bar (13), and in can indentation in the bar (13), on the outer bar (11) of two joint rod bodies (1) connecting thread that matches is arranged, " Γ " shape groove (4) is arranged in the inner chamber of described outer bar (11) and intermediate bar (12), and the projection on this " Γ " shape groove (4) and described interior bar (12) and intermediate bar (13) outer wall matches.
