CN205064954U - A new type of sealing ball plug - Google Patents

Abstract

The utility model discloses a novel sealing ball stopper. The ball plug body is arranged in the hose at the vent hole on the inner wall of the inflatable ball; the ball plug body is provided with a boss which is contacted with the hose; an air inlet hole is formed in the ball plug body; the expansion piece is arranged in the air inlet hole, the outer diameter of the expansion piece is larger than the inner diameter of the air inlet hole, when the expansion piece is plugged into the air inlet hole, the corresponding part of the ball plug body expands and deforms and is in contact with the hose, and the expansion piece is a sphere or a cylinder. The outer diameter of the expansion piece of the utility model is larger than the inner diameter of the air inlet, thus the expansion piece can be expanded and deformed greatly after being placed in the air inlet, the deformed part of the ball plug is contacted with the inside of the hose more closely, on one hand, the air inlet can be blocked, and the air leakage can be prevented; meanwhile, the contact area and the stress degree of the ball plug and the hose are increased, and the ball plug is prevented from falling off.

Description

A new type of sealing ball plug

Technical field:

The utility model belongs to the field of ball plug sealing, in particular to a novel sealing ball plug.

Background technique:

The internal structure of the air inlet nozzle of the existing inflatable ball is as follows: a through hole runs through the surface of the inflatable ball, a hose is provided at the vent hole on the inner wall of the inflatable ball, a ball plug is inserted in the hose, a boss is arranged on the ball plug, and the center of the ball plug is located at the center of the ball plug. Air intake holes are provided. The function of the air inlet is to inflate the sphere, and the elastic body of the ball plug acts as a seal after inflation; the function of the boss is that when the ball plug is placed in the inner wall of the hose, the boss on the ball plug is in close contact with the inner wall of the hose , to prevent the ball plug from falling off. The main disadvantages of the existing structure are: (1) the air inlet hole of the ball plug is not tightly sealed, and air leakage is prone to occur after long-term use or placement; (2) the thickness of the boss on the general ball plug is very thin and the tightness of the hose The contact area is relatively small, and it is easy to cause the ball plug to shift, slide or even fall off.

The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and should not be considered as an acknowledgment or in any form to imply that the information constitutes the prior art already known to those skilled in the art.

Utility model content:

The purpose of this utility model is to provide a new type of sealing ball plug, so as to overcome the above-mentioned defects in the prior art.

In order to achieve the above object, the utility model provides

A new type of sealed ball plug, comprising: a ball plug body, an air inlet hole, and an expansion member; the ball plug body is arranged in a hose at the vent hole on the inner wall of an inflatable ball; The contact boss; the ball plug body is provided with an air inlet; the air inlet is provided with an expansion member, and the outer diameter of the expansion member is larger than the inner diameter of the air inlet. When the expansion member is inserted into the air inlet , the corresponding part of the ball plug body expands and deforms and contacts with the hose.

Preferably, in the technical solution, the expansion member is a sphere or a cylinder.

Compared with the prior art, the utility model has the following beneficial effects:

The outer diameter of the expansion part is larger than the inner diameter of the air intake hole, so that after the expansion part is placed in the air intake hole, the ball plug can be stretched and deformed, and the deformed part of the ball plug is in closer contact with the inside of the hose. On the one hand, the air intake hole can be blocked dead, to prevent air leakage; at the same time, increase the contact area and force between the ball plug and the hose to prevent the ball plug from falling off.

detailed description:

The specific embodiments of the present utility model are described in detail below, but it should be understood that the protection scope of the present utility model is not limited by the specific embodiments.

Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

As shown in Figure 1, a new type of sealed ball plug includes: a ball plug body 1, an air inlet hole 2, and an expansion member 3; the ball plug body 1 is arranged in the hose 4 at the vent hole on the inner wall of the inflatable ball; The ball plug body 1 is provided with a boss 5 in contact with the hose 4; the ball plug body 1 is provided with an air inlet 2; the air inlet 2 is provided with an expansion member 3, and the expansion member 3. The outer diameter is larger than the inner diameter of the air inlet 2. When the expansion member 3 is inserted into the air inlet 2, the corresponding part of the ball plug body 1 expands and deforms and contacts the hose 4; the expansion member 3 is a sphere or cylinder.

The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. These descriptions are not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can realize and utilize various exemplary embodiments of the present invention and various Different options and changes. It is intended that the scope of the invention be defined by the claims and their equivalents.
