Technical Field

[0001] This utility model relates to the field of football bladder technology, and in particular to a football bladder with good sealing performance. Background Technology

[0002] Football is a sport, and as a sport, it is very popular worldwide.

[0003] A soccer ball consists of an inner bladder and a surface structure. The inner bladder contains a valve core to inject air into it and cause it to expand. However, the impact force and time of use cause the valve core to age, resulting in air leakage. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem of air leakage in the valve core of the inner bladder due to aging of the football in the prior art, and to propose a football inner bladder with good sealing performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A well-sealed soccer ball bladder includes an inner bladder body and a valve core body with one end penetrating through the outer wall of the inner bladder body, and further includes:

[0007] A sealing element is disposed inside the inner liner body, and one end of the valve core body located inside the inner liner body is threadedly connected to the sealing element, so as to achieve a sealing effect by sealing the valve core body through the sealing element.

[0008] In one feasible embodiment, the seal includes:

[0009] A sealing cover, the top of which is threadedly connected to one end of the valve core body via a connecting pipe, and the sealing cover is in communication with the valve core body; a vent is provided at the bottom of the sealing cover.

[0010] Four connecting telescopic components are respectively disposed at the four inner top corners of the sealing cover. The sealing cover is connected to a sealing plate through the connecting telescopic components, and the sealing plate is located below the sealing cover.

[0011] In one feasible embodiment, the connecting telescopic member includes:

[0012] A limiting tube, one end of which is open, and the other end of which is sealed is fixedly disposed on the top inner wall of the sealing cover;

[0013] A spring, one end of which is fixedly disposed on the top inner wall of the limiting tube;

[0014] A connecting rope, one end of which is fixedly wrapped around the other end of the spring, and the other end of which passes through the bottom of the sealing cover and is connected to the sealing plate.

[0015] In one feasible embodiment, the top of the sealing plate is provided with a sealing protrusion, and the bottom of the sealing cover is provided with a sealing groove that fits into the sealing protrusion on the outer periphery of the sealing plate.

[0016] In one feasible embodiment, both the top of the sealing protrusion and the inner wall of the sealing groove are provided with sealing rubber.

[0017] In one feasible embodiment, the sealing plate is made of plastic sheet, and the limiting tube is made of nylon rope.

[0018] The beneficial effects of this utility model are as follows:

[0035] Example

[0036] Reference Figures 1 to 5 This invention addresses the technical problem of air leakage from the valve core of a soccer ball due to aging, by providing a soccer ball bladder with good sealing performance. The bladder includes an inner bladder body 1 and a valve core body 2, one end of which penetrates the outer wall of the inner bladder body 1, allowing air to be injected into the inner bladder body 1 via the valve core body 2. It also includes a sealing element 3, which is disposed inside the inner bladder body 1. The end of the valve core body 2 located inside the inner bladder body 1 is threadedly connected to the sealing element 3, achieving a sealing effect by sealing the valve core body 2. Specifically, the sealing element 3 includes a sealing cover 31 and four connecting telescopic elements 33. The top of the sealing cover 31 is threadedly connected to one end of the valve core body 2 via a connecting pipe 32, and the sealing cover 31 communicates with the valve core body 2. The threaded connection facilitates installation before the inner bladder is formed. A vent 311 is provided at the bottom of the sealing cover 31, allowing gas to be injected into the interior of the inner bladder body 1. Four connecting telescopic components 33 are respectively set at the four corners of the inner top of the sealing cover 31. The sealing cover 31 is connected to the sealing plate 34 through the connecting telescopic components 33. The sealing plate 34 is located below the sealing cover 31. The sealing plate 34 can be connected to the sealing cover 31 through the setting of the connecting telescopic components 33, and the sealing plate 34 can be attached to the bottom of the sealing cover 31. This allows the vent 311 at the bottom of the sealing cover 31 to be blocked in daily use, so that the air inside the inner liner body 1 cannot leak from the valve core body 2.

[0037] Please refer to Figures 3 to 4As shown, in this embodiment, for ease of description of multiple connecting telescopic components 33, one connecting telescopic component 33 is used as an example. The connecting telescopic component 33 includes: a limiting tube 331, a spring 332, and a connecting rope 333. One end of the limiting tube 331 is open, and the sealed end of the limiting tube 331 is fixedly disposed on the top inner wall of the sealing cover 31. One end of the spring 332 is fixedly disposed on the top inner wall of the limiting tube 331; here, the limiting tube 331 can limit the spring 332, preventing the spring 332 from bending during use. One end of the connecting rope 333 is fixedly wrapped around the other end of the spring 332, and the other end of the connecting rope 333 passes through the bottom of the sealing cover 31 and is connected to the sealing plate 34; it should be noted that the limiting tube 331 is made of nylon rope material, and the connecting rope 333 made of this material is not easily broken by tensile force during use, increasing the robustness of the device. In this embodiment, when the valve core body 2 is being inflated, the air pushes the sealing plate 34 away from the bottom of the sealing cover 31. The sealing plate 34, pulled by the connecting rope 333, causes the spring 332 to deform and extend, thus exposing the vent 311 at the bottom of the sealing cover 31 and allowing air to be injected into the inner liner body 1. Conversely, when the valve core body 2 is not in use, the spring 332 returns to its original position, pulling the sealing plate 34 to fit against the bottom of the sealing cover 31 and sealing the vent 311. It should be noted that the sealing plate 34 is made of plastic, a material that makes it more easily pushed by the injected air during use.

[0038] In one feasible embodiment, in order to better seal the vent 311 when the sealing plate 34 and the bottom of the sealing cover 31 are attached, a sealing protrusion 341 is provided on the top of the sealing plate 34, and a sealing groove (not shown in the figure) is provided on the bottom of the sealing cover 31 on the outer periphery of the sealing plate 34 to fit the sealing protrusion 341. Both the top of the sealing protrusion 341 and the inner wall of the sealing groove are provided with sealing rubber.

[0039] Working principle

[0040] When using the football bladder, air can be injected into the bladder body 1 through the valve core body 2. During the injection process, air enters the sealing cover 31 and pushes the sealing plate 34 away from the bottom of the sealing cover 31 through the vent 311. At the same time, the sealing plate 34 will pull the spring 332 through the connecting rope 333 to deform and extend, thereby injecting air into the bladder body 1. Under normal use, the sealing plate 34, which loses the air push, will retract and fit against the bottom of the sealing cover 31 through the reset of the spring 332, thereby sealing the vent 311 at the bottom of the sealing cover 31 and achieving the effect of preventing air leakage and increasing the sealing performance of the football bladder.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
