Description

Improvement of Aluminum Extrusion Stick Structure for Lacrosse

technical field

The utility model relates to an improved structure of an aluminum extruded club for tennis, in particular to an aluminum extruded club which can reduce weight and increase its surface strength.

Background technique

Lacrosse is a game in which two teams attack each other. The side with more goals is the winner. Like a football game, it also has a formation of goals, forwards, midfielders and defenders. Lacrosse Players do not use their hands or feet to control the ball, but use a special bat to control the ball, and the ball used in the game is a little bigger than a baseball, with elasticity and weight, so the attack needs to be flexible, so the striker The bat used is shorter, about 4 feet long, and the defender uses a slightly longer stick to increase the range of his defense, and a net is set and locked on the top of the stick, and the game The player in the game needs to keep turning the stick and use the centrifugal force to collect the ball in the net. Therefore, every player needs to be familiar with the movement of turning the stick and the net before he can shoot the ball into the opponent's goal and score. , but due to the extremely fast speed of the ball, it is very easy to cause players to collide with each other during the game, and each player holds a stick in his hand, so players use the stick as a weapon to collide with each other during the game. However, the currently used stick Tennis club 1, all as shown in Fig. 1～Fig. The end is sleeved with a rear cover 13 and formed, but such a club has the following disadvantages:

1. In order to make the players have the best flexibility in the game, the stick will control the weight of the tennis stick 1, and the net is a standard competition item, and its weight is fixed. Therefore, Generally, the aluminum-extruded club 11 is formed with an aluminum-extruded hollow tube to reduce its weight. During the game, players hold the aluminum-extruded club 11 with both hands and run fast. Therefore, in the process of running fast and grabbing the ball, the club 11 is used as a weapon to collide with each other, which often causes the aluminum extruded club 11 to bend or sag during the collision due to the hollow tube, thereby causing the extruded aluminum club 11 to bend or sag during the collision. Damage to club 11 .

2. Conversely, if the strength of the extruded aluminum club 11 is to be strengthened to reduce the degree of bending or dent damage during collisions, the thickness of the hollow tube wall must be increased. However, once the thickness of the tube wall is increased , the weight of its extruded aluminum club 11 is relatively increased, which on the contrary affects the flexibility of players running and grabbing the ball in the game.

3. During the game, players use the stick as a weapon to collide with each other, often causing the stick to be dented or bent due to the collision, but the accuracy of turning the stick and the net is the most important thing in stick tennis. One ring, and the depression or bending of the aluminum extruded ball stick 11 will often seriously affect the accuracy of the player's rotation of the aluminum extruded ball stick 11, thereby affecting the accuracy of ball control and throwing the ball on the net, and then affecting the game. result.

Therefore, the creator of this utility model is based on his many years of experience in aluminum extrusion manufacturing and design, hoping to change the predicament of existing clubs that affect the game due to poor strength, and is actively researching and improving, and after many tests And change, finally get the generation of the present utility model.

Utility model content

The main purpose of the utility model is to provide a lightweight and strong aluminum extruded lacrosse club.

The utility model is an improved structure of an aluminum extruded club for tennis. The front end of a hollow aluminum extruded club is sheathed and locked to a net, and the tail end of the aluminum extruded club is It consists of a rear cover, wherein: the aluminum extruded ball stick is a hollow tube, and an inner column is arranged in the hollow tube.

The structure improvement of the aluminum extruded club for lacrosse tennis, wherein the hollow aluminum extruded club is a hollow polygonal tube.

The structure improvement of the aluminum extruded club for lacrosse, wherein, the tube of the hollow aluminum extruded club is integrally formed with an inner column.

The structure improvement of the aluminum extruded club for lacrosse, wherein, the groove in the tube of the hollow aluminum extruded club can be implanted into an inner column.

In the structure improvement of the aluminum extruded club for lacrosse tennis, the thickness or quantity of the inner column can be increased according to the requirement.

The structure improvement of the aluminum extruded club of the lacrosse tennis ball is improved, wherein the inner column can be in various shapes according to requirements.

In the improved structure of the aluminum extruded club for lacrosse tennis, the inner column may be in the shape of a cross.

The utility model can enhance the surface strength of the aluminum extruded club through the design of the aluminum extruded club designed by the inner column of the hollow tube, and in the game, it can slow down the degree of damage of the club from bending or sag, or because of its The surface strength is enhanced, and when the strength meets the requirements, the thickness of the hollow tube wall can be reduced, thereby achieving the purpose of light weight, so that players can achieve a more flexible use of the stick during the game, and its efficacy is greatly improved. The improvement is beyond doubt.

Hereinafter, with regard to the structural content and the characteristics thereof of the present utility model, cooperate the drawings to describe in detail as follows:
