Description

  The present invention relates to inflating, and more particularly, to an original inflating structure configuration design having a balloon knotting assist function.

  The term “pneumatic inflating” as used in the present invention is not an inflating for filling tires, but a statement of a specific type of inflating structure for filling balloons with air. deep.

  As known to related users, the conventional air filling structure for filling air into a balloon is provided with a cylindrical body as a typical structural form, and fits into the opening of the balloon in the head of the cylindrical body. A projecting triangular pyramid-shaped air inlet is provided, and a handle projecting from the tail portion of the cylinder is provided. The handle is connected to a piston in the cylinder, with the shaft rod extending into the cylinder. However, it pushes and pulls the handle repeatedly so that the user compresses the air, but the compressed air balloon flows out of the air inlet and achieves the function and purpose of filling the balloon with air. Will do.

  In addition to the above-described form, the conventional balloon-filling air-filling structure for the balloon has another form in which the handle and the shaft rod are provided in the head of the cylinder and the air inlet is provided at the handle.

  However, even if the conventional air filling structure for air filling of the balloon corresponds to any of the above-mentioned forms, it is understood from the widely used experience that there are still insufficient points, for example, When the user completes the filling of the balloon with the air, the conventional air structure is designed so that no auxiliary design is provided for tying the opening of the balloon. To connect the openings, there is a drawback that seems to be very cumbersome and inconvenient, and it is necessary to improve and break through.

  Therefore, it is the user's desire to research and develop an original structure that is more ideal and practical with respect to the problems existing in the above-described conventional balloon-filled air-filling structure. It is also the goal and method that the related industry thinks to break through.

  In view of this, the inventor has many years of experience in manufacturing development and design of related products, and after designing and carefully evaluating the above-mentioned goals, finally, a practical invention can be obtained. That is why.

  The present invention aims to provide a pneumatic structure with a knotting assist function, and the problem to be solved is improved and overcome with the goal of developing an original pneumatic structure that is more ideal and practical. That is.

  As one aspect of the present invention, a cylinder, a piston, an operating shaft, a handle and an air inlet structure dedicated to air filling of a balloon, the piston is capable of reciprocating and has a cylindrical structure. The working shaft is provided in the working space, the inside of the working shaft is connected to the piston, the outside is extended from one side of the cylindrical body to the outside, the handle is connected to the outside of the working shaft, and the air inlet is It is a triangular pyramid-like projecting tube provided at a place connected to the working space of the cylinder, and a knotting auxiliary part is further added at a position spaced apart from the air inlet, A protrusion and an inner concave edge for tie at the tip of the protrusion are provided. Due to such an original design, compared with the background art, the present invention allows the user to directly connect the protruding portion of the knotting assisting portion and the inner concave portion of the knotting aid when the balloon fitted in the air inlet is completely filled with air. As a guide mechanism, the rim is turned around the balloon opening to achieve the function and purpose of the knotting assist, and the added value and function of the inflated product are greatly improved.

  In another aspect of the present invention, a threading portion for positioning an existing thread is further provided at the position where the protrusion of the knotting assisting portion and the air inlet are provided, and the tip of the thread is attached to the tip of the thread. Extending to a position close to one side of the inner rim for tying, so that when the opening of the balloon is turned and tied, the ends of the yarn are tied together, and the yarn is used as a yarn for holding the balloon. It is provided to do.

  The fact of the effect improvement by this invention is as follows. In the “pneumatic structure with a knotting assist function” posted in the present invention, the present invention is based on the background technology by an original design in which a knotting assisting part is further added at a distance from the air inlet. In comparison, when the balloon fitted in the air inlet is completely filled with air, the user directly turns the balloon opening by using the protrusion of the knotting assisting portion and the inner concave edge for tying as a guide mechanism. It has practicality and inventive step, which achieves the function and purpose of tying assistance and greatly improves the added value and function of inflated products.

  The new effects of the present invention are as follows. At the place where the protrusion of the knotting assisting portion and the air injection port are provided, a threading part for allowing the existing thread to pass therethrough is further added, and the tip of the thread is connected to the inner recess for knotting. When the balloon opening is rotated and tied so as to extend to one side of the edge, the ends of the yarn are tied together, and the yarn is used as a yarn that holds the balloon. As a result, there is an effect and an inventive step that a thread for holding the balloon can be tied at the same time as the opening of the balloon is tied.
