Balloon needle structure

The present invention provides a ballooning needle structure, which is mainly used for inflation of inflatable balls, and coexists with different nozzle shapes at both ends of the ball needle, so that it can be selectively combined with the balloon valve port. According to the inflation requirements of inflatable balls of different vent type, it is suitable for practicality and convenience.

According to the conventional inflatable ball (such as soft tennis, hard tennis, volleyball, basketball, etc.), the structure usually has an inflation hole or mark at a predetermined part of the ball, which is used for inflating with the ball and the air pump, and using the gas. Filled inside the sphere to maintain its sphere shape.

However, under normal use conditions, such inflatable balls are inevitably subject to natural deflation. Due to the leakage of internal gas, the hardness of the sphere is insufficient, and even its overall functionality is affected. When the ball is found to be under-inflated, it needs to be inflated to restore its shape and functionality.

In addition to the large-scale air pumping cylinders used in the inflation work of such inflatable balls, in addition to the convenience of carrying and use, there is a simple balloon needle suitable for hand-held pressure control, please Referring to Figures 1 to 4, a balloon (10) suitable for hand pressure control is mainly provided. The balloon (10) is usually made of rubber material and has a predetermined position at the balloon (10). Valve port (11) for optional ball needles (12) In combination with the plug group, the ball needles (12) are made of metal material, and are integrally formed at the rear end thereof into a plug group portion (13) which can fit into the valve port (11) of the balloon (10). The material property of the balloon (10) is used to form a tight binding effect on the plug portion (13) of the ball needle (12), and the front end of the ball needle (12) can be made into a round head nozzle (14) or The oblique mouth nozzle (15) is further provided with an exposed thread segment (16) at the front end of the plug group portion (13) according to different inflation type requirements of the inflatable air hole or the marking of the inflatable ball, and the thread segment is used. (16) The protective sleeve screw can be used to cover the ball needle (12), thereby constituting the basic functional structure of the conventional hand pressure type simple balloon needle.

However, it is customary to use a balloon needle in the structure. It can only choose to assemble a round-head nozzle or a slant-mouth needle, that is, its balloon needle can only be applied to a single-type inflatable ventilating ball, resulting in its use. Restrictions and inconveniences, especially when inflating the inflatable ball temporarily, may not be able to smoothly perform the inflation operation because the applicable balloon needle is not found. To avoid such problems, the user must prepare two different types at the same time. The type of balloon needle not only causes an increase in the purchase cost, but also causes trouble and inconvenience in the derivation. It is difficult to call it ideal and perfect, and it is necessary to try to solve the improvement.

The creation of this creation is mainly due to the fact that the conventional hand-pressed simple balloon needle only has a single type of ball needle, which makes it unsuitable for the inflation requirements of various inflatable balls, which seriously affects the convenience of its use. And practicality, based on the years of experience and technology of the creator in the relevant industry, and then researched and created the balloon structure of the creation.

In order to meet the inflation requirements of various inflatable balls, the design is based on the different types of nozzles at different ends of the ball needle, and the combination of the valve plugs that match the balloon valve port is modified. It is located in the middle of the ball needle, so that different types of balloon needles can be obtained by combining the different ends of the ball with the balloon insert, which is suitable for practicality and convenience.

The structure of the balloon needle of this creation, through the structure of the structure, enables a single balloon to be matched with the reversing insert of the ball needle, and is suitable for the inflation demand of various inflatable balls, and can reduce the purchase cost and solve the carrying Problems that give better use convenience and usability.
