Abstract

The utility model relates to telescopic nunchakus comprising two stick bodies (1) connected by a chain (2). Each stick body is divided into three telescopic sticks including an outer stick (11), a middle stick (12) and an inner stick (13); the chain (2) is connected to the inside of a piton block (3) in the inner stick (13); the outer sticks of the two stick bodies are provided with connecting screw threads which are matched with each other; reverse L-shaped troughs (4) are arranged in both the inner cavities of the outer stick (11) and the middle stick (12) and are matched with bulges on the outer walls of the inner stick (12) and the middle stick (13). The three telescopic sticks of the stick bodies can be shrunk into one, the chain can be completely shrunk into the inner stick, and the two stick bodies are connected by the screw threads to combine into a whole. The utility model has the advantages of small volume, light weight, convenient carryover, and the like.

Description

A retractable nunchaku

technical field

The utility model relates to a sports appliance, in particular to a nunchaku.

Background technique

Today, nunchakus can be used not only as a self-defense tool, but also for fitness, entertainment or other games. The existing nunchaku mainly has the following two major defects:

1. It is bulky and inconvenient to carry, which is not conducive to self-defense.

2. The chain cannot be retracted into the stick body, which is not beautiful enough.

Contents of the invention

The technical problem to be solved by the utility model is to provide a retractable nunchaku to solve the defect of inconvenient portability in the prior art.

Technical solutions

A retractable nunchaku, which is composed of two-section stick bodies connected by chains. The stick body is divided into three telescopic rods: an outer rod, a middle rod, and an inner rod. The chain is connected to the piston block in the inner rod. There are matching connecting threads on the outer rod of the stick body. There are "Γ" shaped grooves in the inner cavity of the outer rod and the middle rod. match the protrusions.

Beneficial effect

The three telescopic rods of the stick body of the utility model can be shrunk into one, the chain can be fully retracted into the inner rod, and the two stick bodies are suitably combined into one body, which has the advantages of small size, light weight, and convenient portability.

Detailed ways

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that those skilled in the art may make various changes or modifications to the present invention after reading the content taught by the present utility model, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

Example 1

As shown in the figure, a telescopic nunchaku consists of two stick bodies 1 connected by chains 2. The rod and the chain 2 are connected to the piston block 3 in the inner rod 13. There are matching connecting threads on the outer rod 11 of the two stick bodies 1. The inner chambers of the outer rod 11 and the middle rod 12 have " Γ "shaped groove 4, this " Γ " shaped groove 4 is matched with the protrusion on the outer wall of the inner rod 12 and the middle rod 13 .

The utility model is realized by the following methods: firstly, unscrew the outer rod, and pull out two telescopic rods through the chain, so that the protrusion of the inner rod slides relatively in the inner groove of the outer rod connected to it, and pulls out to a certain length Finally, rotate axially so that the telescopic rod cannot slide axially. After being fully stretched out, the structure is basically the same as that of ordinary nunchakus.

Claims (1)

1. A retractable nunchaku consisting of two stick bodies (1) connected by chains (2), characterized in that: the stick body (1) is divided into an outer rod (11), a middle rod (12 ), three telescopic rods of the inner rod (13), the chain (2) is connected in the piston block (3) in the inner rod (13), and can be retracted in the inner rod (13), the two-section stick body (1) There are matching connecting threads on the outer rod (11), and there are "Γ" shaped grooves (4) in the inner cavities of the outer rod (11) and the middle rod (12). This "Γ" shaped groove (4) ) and the protrusions on the outer wall of the inner rod (12) and the middle rod (13) are matched.
