CN201740463U - Nunchakus - Google Patents

Abstract

The utility model provides nunchakus comprising two stick bodies and a connecting chain connected with the two stick bodies. The nunchakus are characterized in that each stick body has a closed hollow cavity; one end of each stick body, close to the connecting chain, is provided with a charging connector; the stick bodies are internally provided with water absorbing materials; and the stick bodies are made of flexible rubber. In the utility model, the hardness of the stick bodies can be adjusted by adjusting the air charged in the stick bodies, and the quality can be adjusted by controlling the amount of water injected in the stick bodies, thus being very suitable for beginners of nunchakus to use.

Description

A kind of two rod that cuts

Technical field:

The utility model relates to two rod technology of cutting.

Background technology:

Two sections rods are a kind of learning martial arts or the equipment of body-building, two at present rod bodies that cut rods by material constitute can be divided into steel, hard rubber, solid wood with the soft cotton-padded covering of reel band.For the beginner, two rods that cut of the soft cotton-padded covering of reel band are owing to its quality softness, lighter weight, the willful murder overstrain is faint, easy left-hand seat, but also, make the person of practising be difficult to hold the size of having an effect and cause exercise not harmony, cut rod because its hardness is bigger and the hard of other types is two just because its quality is too light, the willful murder overstrain is bigger, and the beginner injures oneself when exercise easily.

Summary of the invention:

The purpose of the utility model is:

A kind of safe in utilization and adjustable two rods that cut of quality are proposed, to overcome the deficiency that two sections rods of prior art exist when being used to practise.

For realizing the purpose of the utility model, intend adopting following technology to be achieved:

Two rod bodies and the connection chain that is connected two rod bodies are arranged, it is characterized in that: described rod body is airtight hollow cavity, and is provided with charging connector near connection chain one end side surface on the rod body.

In such scheme, be provided with absorbent material in the described rod body.

In such scheme, described rod body is that flexible rubber is made.

Compared with prior art, the beneficial effects of the utility model are:

Because the rod body is airtight hollow cavity, the rod body is provided with charging connector, and the rod body is that flexible rubber is made, and this has just reduced two lethality when cutting rods and hitting human body greatly; Owing to be provided with absorbent material in the rod body, then can in the rod body, inject the water of suitable quality again, make the person of practising when exercise, can grasp dynamics and degrees of coordination better according to the person's of practising concrete condition.

Description of drawings:

Fig. 1 has illustrated structure of the present utility model.

1: the rod body; 2: absorbent material; 3: charging connector; 4: connection chain.

The specific embodiment:

Key of the present utility model is: rod body 1 is airtight hollow cavity, and is provided with charging connector 3 near connection chain 4 one ends on the rod body 2; Be provided with absorbent material 2 in the described rod body 1; Described rod body 1 is that flexible rubber is made.

Described absorbent material can be a sponge, its effect is: when whipping rod body 1, water in the rod body 1 is difficult for flowing, and mass ratio is more even in the longitudinal direction to make rod body 1, can avoid water flowing to the mass motion trajectory generation influence of rod body 1 in the whipping process in rod body 1.

Described charging connector 3 is to be used to charge and discharge the sky G﹠W, and its structure is consistent with the air-filled pore structure of common football, basketball.

With reference to the accompanying drawings 1.When the beginner uses the utility model, can in rod body 1, inject a spot of water by charging connector 3 earlier, in rod body 1, squeeze into compressed air by charging connector 3 with air pump or inflator then.Because the less lighter weight of water in the rod body 1, lethality is faint, squeezes into the suitable height (as: 300Kpa) of compressed air air pressure in the rod body 1.

After the beginner has grasped the elemental motion main points of two sections rods preferably, can in rod body 1, inject more water, make to the utlity model has bigger quality, the beginner can further practise grasping dynamics and the degrees of coordination when use is two to cut rod.Under the more situation of the water that injects in rod body 1, the compressed air air pressure of squeezing in the rod body 1 should suitably reduce, and does not produce tangible bending as long as guarantee rod body 1 in the whipping process.Like this, even quality of the present utility model is bigger, but its hardness is low, and contact area is bigger when impacting human body, and pressure is little, and human body does not just have tangible pain, can be not injured.Also can bring into play better in the training process in air exercise, not worry that two rods that cut injure the adversary.

Claims (3)

1. two rod that cuts comprises two rod bodies (1) and the connection chain (4) that is connected two rod bodies (1), and it is characterized in that: described rod body (1) is airtight hollow cavity, and the end side surface that rod body (1) is gone up near connection chain (4) is provided with charging connector (3).

2. a kind of two rods that cut as claimed in claim 1 is characterized in that: be provided with absorbent material (2) in the described rod body (1).

3. one kind a kind of pair as claimed in claim 1 is cut rods, and it is characterized in that: described rod body (1) is that flexible rubber is made.
