Description

Improved barrel structure

The present invention relates to the technical field of a large gun, in particular to the category of a conveniently portable, high-strength large gun barrel.

Press, the big gun is the main weapon in the ancient battlefield, please refer to Figure 6, a conventional big gun 9 uses wood or bamboo to make the gun shaft, the length of the known big gun 9 is more than 3 meters, and the user uses both hands to move forward and backward After holding a gun root 91 and a gun body 92 of this known large gun 9, in the arena, performance field or for the purpose of demonstration, for different parts such as the mask, breastplate, waist of the opposite party, use the known The head 93 of the big gun 9 stabs, and the game is played for the purpose of obtaining the highest score within a limited time.

However, due to the changes in material, length, weight, etc. of this conventional large gun, based on the fairness, consistency, and safety requirements of modern competitive sports, it cannot meet the requirements of toughness such as homogeneity and equal weight. Knowing that the big gun 9 is integrally formed, it is inconvenient to carry, and it may be broken after being knocked against the opponent in the game, which may cause a stabbing risk, and the root 91 of the gun is mostly flat or blunt. The palms are tightly closed, and if the reaction force generated at the moment of counterattack is too strong and cannot be removed, it may cause injuries or even comminuted fractures to the arm holding the gun. Therefore, it is really necessary to improve it.

For this reason, in view of above-mentioned this conventional big gun generation problem point, the creator of the present invention develops the improved structure of the new type of gun shaft with great effort, so the main purpose of the new type is to improve the structure of a kind of gun shaft with toughness and strength; Main purpose: to improve the structure of a gun barrel that is convenient to carry; another purpose of the present invention: to improve the structure of a gun barrel that is safely held.

In order to achieve the above object, the technical means used in the present invention are as follows:

The present invention relates to an improved structure of a gun rod, which includes: a first rod body, the first rod body is made of carbon fiber material, and one end of the first rod body is provided with a joint, and the joint part is provided with an internal thread, And the front end and the end of the internal thread are respectively provided with an inner chamfer; and a second rod body, the second rod body is made of carbon fiber material, and one end of the second rod body is provided with a butt joint, and the butt joint is connected It is arranged at the joint portion of the first rod body.

The above-mentioned first rod body is provided with a gun root, and the gun root is connected to the other end of the first rod body; and the second rod body is provided with a gun head, and the gun head is connected to the second rod body. The other end of the two rods.

Above-mentioned this gun root is the egg shape with circular arc.

The butt joint portion of the second rod body is provided with an external thread corresponding to the joint portion of the first rod body, and the front end and the end of the external thread are respectively provided with an external chamfer, and the external chamfer fits the first rod The inner chamfer of the body.

The first rod has a first length of at least 150 cm, and the second rod has a second length of at least 150 cm.

This novel by above-mentioned technical means, can reach following effect: 1. With the inner chamfer of the joint part and the outer chamfer of the butt joint part, when the first rod body and the second rod body are impacted, the strength of the force is determined by the inner chamfer and the outer chamfer. The inclined surface of the corner bears, does not damage the screw teeth, prolongs the service life, and ensures the stability of the first rod body and the second rod body. 2. In the present invention, when the first rod body and the second rod body are separated, the length of the first rod body and the second rod body is about 150 cm, which is convenient to carry. 3. In this new model, the root of the gun is set in an egg shape with a circular arc, and the contact area between the root of the gun and the palm is enlarged, which effectively reduces the problem of the palm being worn out and falling out of the hand.

The present invention relates to an improved gun barrel structure, which is convenient to carry and increases the overall strength of a gun barrel A. It includes: a first rod body 1 and a second rod body 2;

The above-mentioned first rod body 1, as shown in Fig. 1 to Fig. 3, is that the first rod body 1 is made of carbon fiber material, and one end of the first rod body 1 is provided with a joint portion 11, and the other end is provided with a Gun root 12, and this gun root 12 is the egg shape with circular arc.

The above-mentioned second rod body 2, please refer to Fig. 1 to Fig. 3 again, is that the second rod body 2 is made of carbon fiber material, and one end of the second rod body 2 is provided with a butt joint 21, and the other end is connected with a gun The gun head 22 is made of elastic material, and the joint portion 21 of the second rod body 2 is connected to the joint portion 11 of the first rod body 1 .

Further, please refer to FIG. 3 , the above-mentioned joint portion 11 of the first rod body 1 is provided with an internal thread 13 , and the front end and the end of the internal thread 13 are respectively provided with an inner chamfer 14 , and the butt joint of the second rod body 2 Part 21 is provided with an external thread 23 corresponding to the joint portion 11 of the first rod body 1, and the front end and the end of the external thread 23 are respectively provided with an outer chamfer 24, and the outer chamfer 24 fits the first rod body 1 inside chamfer 14.

In particular, referring to Fig. 1, the first rod body 1 is provided with a first length W1 of at least 150 centimeters, and the second rod body 2 is provided with a second length W2 of at least 150 centimeters, so the The first rod body 1 and the second rod body 2 are easy to carry after being disassembled, and the first rod body 1 and the second rod body 2 use carbon fiber instead of natural materials to effectively control the toughness of the gun shaft A and achieve the goal of competition equipment. Standardization and fairness, while improving security.

Therefore, the present invention provides a preferred embodiment for improving the structure of the gun shaft A, please refer to Figures 2 to 4, and when it is intended to be used on the field, the internal thread 13 of the joint part 11 and the external thread 23 of the docking part 21 are locked relative to each other At the same time, the outer chamfer 24 and the inner chamfer 14 are in contact with each other. When using the gun shaft A to compete with the opponent's weapon and hit, hit, etc., when the joint part 11 and the butt joint part 21 are subjected to impact force, the The external chamfer 24 and the internal chamfer 14 bear impact together, reduce the damage to the internal thread 13 and the external thread 23, prolong the life of the internal thread 13 and the external thread 23, and ensure that the first rod body 1 and the The stability of the second rod body 2.

Further, please refer to Fig. 4 and Fig. 5, the user holds the first rod body 1 with one hand and the gun root 12 with the other hand. The rounded egg-shaped gun root 12 can come out along the shape of the palm 3, avoiding the reaction force transmitted to the forearm to cause injury or even comminuted fracture. In addition, the shape of the gun root 12 enlarges the contact area between the palm 3 and the gun root 12 , and then improve the stability of holding the gun root 12.

To sum up, this new model involves an improvement in the structure of a gun barrel, and its structure has never been seen in books or public use. It truly meets the requirements for a new patent application. I sincerely hope that the bureau will grant the patent as soon as possible, and I will pray for it;

It needs to be stated that the above is the technical principle used in the specific embodiment of this case. If the changes made according to the concept of this case do not exceed the spirit covered by this specification and drawings, all It should be submitted to Chen Ming within the scope of the patent application in this case.
