Abstract

The utility model provides an anti-explosion basketball bladder, and relates to the field of basketballs. The anti-explosion type basketball bladder comprises an outer-layer bladder skin, an inflation inlet is formed in one side of the outer-layer bladder skin, an inner-layer bladder skin is arranged in the outer-layer bladder skin, one end of the inner-layer bladder skin extends to the outer side of the outer-layer bladder skin, and the interior of a protruding part of the inner-layer bladder skin is in friction connection with a sealing piece for blocking exhaust. According to the anti-explosion type basketball bladder, the inner-layer bladder skin is inflated firstly, then the outer-layer bladder skin is inflated, when a basketball collides, the outer-layer bladder skin extrudes the inner-layer bladder skin, when violent collision occurs, gas of the inner-layer bladder skin extrudes the sealing piece, so that the sealing piece is separated from the inner-layer bladder skin, exhausting is conducted, and therefore the inner bladder can be prevented from being broken.

Description

Technical Field

[0001] The utility model relates to the technical field of basketballs, in particular to an explosion-proof basketball bladder. Background Art

[0002] The inner bladder plays a supporting role and is mostly filled with gas. The ball is spherical in shape. This spherical inner bladder is called a ball bladder. Generally, the ball bladder is a soft and elastic bag made of rubber. It is placed inside the ball and inflated to make the ball elastic.

[0003] An existing patent for an explosion-proof basketball bladder (CN213589668U) discloses that when the air pressure in the rubber bladder 4 is sufficient, the air pressure will push the pressure plate 5, and the air plug 11 and the positioning cylinder 8 fixed to the pressure plate 5 by rivets 12 will move in the track cylinder 6, and then the air plug will block the air inlet pipe 9. The spring 10 can prevent the air plug 11 from blocking the air inlet pipe 9 when it is not inflated, and the excess air in the air inlet pipe 9 will be discharged from the air outlet 7. Finally, the carbon fiber 3 installed in the basketball bladder can enhance the strength of the bladder, and the thin steel wire 2 can prevent the basketball bladder from bursting during use.

[0004] Since components such as rivets, springs, and pressure plates are arranged inside the inner liner, it is easy for the liner to be squeezed and broken when it is deflated. At the same time, due to the arrangement of the components, the center of gravity of the ball is deflected after it is formed into a ball, and the flight trajectory is unstable. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an explosion-proof basketball bladder, which solves the problems raised in the background technology.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: an explosion-proof basketball bladder, including an outer bladder skin, one side of the outer bladder skin is provided with an inflation port, an inner bladder skin is provided inside the outer bladder skin, one end of the inner bladder skin extends to the outside of the outer bladder skin, and the protrusion of the inner bladder skin is frictionally connected with a seal that hinders exhaust.

[0007] Preferably, the sealing member is symmetrically arranged with respect to the inflation port.

[0008] Preferably, hollow protrusions communicating with the inner layer of bile skin are arranged around the inner layer of bile skin, and the hollow protrusions are fixedly connected to the outer layer of bile skin.

[0009] Preferably, the outer edge of the sealing member is provided with a protrusion for rubbing against the inner layer of the bile skin.

[0010] Preferably, the sealing member is divided into an outer hard friction portion and an air injection port wrapped inside the outer hard friction portion.

[0011] The utility model has the following beneficial effects:

[0012] The explosion-proof basketball bladder is first inflated into the inner bladder skin and then into the outer bladder skin. When the basketball collides, the outer bladder skin squeezes the inner bladder skin. When a violent collision occurs, the gas in the inner bladder skin squeezes the seal so that the seal is separated from the inner bladder skin, and exhaust occurs, thereby preventing the inner bladder from rupturing.

[0013] The explosion-proof basketball bladder has a sealing component which is divided into an outer hard friction portion and an air injection port wrapped inside the outer hard friction portion. With such an arrangement, the inner bladder skin can be inflated through the friction portion. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides an explosion-proof basketball bladder:

[0020] Embodiment 1, as Figure 1-3 As shown, it includes an outer bile skin 1, one side of the outer bile skin 1 is provided with an inflation port 2, the inner layer of the bile skin 3 is provided inside the outer bile skin 1, the inner layer of the bile skin 3 and the outer layer of the bile skin 1 are both composed of two symmetrical halves, the inner layer of the bile skin 3 is fixedly wrapped inside the outer layer of the bile skin 1, one end of the inner layer of the bile skin 3 extends to the outside of the outer layer of the bile skin 1, and the protruding part of the inner layer of the bile skin 3 is frictionally connected with a seal 4 that hinders exhaust.

[0021] The sealing member 4 and the inflation port 2 are symmetrically arranged, and such an arrangement can make the inner liner symmetrical.

[0022] Hollow protrusions 5 communicating with the inner bile skin 3 are arranged around the inner bile skin 3 , and the hollow protrusions 5 are fixedly connected to the outer bile skin 1 . Such an arrangement can prevent the inner bile skin 3 from shaking in the inner bile.

[0023] The outer edge of the seal 4 is provided with a protrusion that rubs against the inner bile skin 3. Such a setting can increase the friction force, and the response pressure of the inner bile skin 3 when exhausting gas can be controlled by controlling the friction force between the protrusion and the inner bile skin 3.

[0024] The sealing member 4 is divided into an outer hard friction portion 401 and an air injection port 402 wrapped inside the outer hard friction portion 401 . Such a configuration can facilitate the inflation of the inner layer of the bile skin 3 .

[0025] When in use, first inflate the inner bladder skin 3, then inflate the outer bladder skin 1. When the basketball collides, the outer bladder skin 1 squeezes the inner bladder skin 3. When a violent collision occurs, the gas of the inner bladder skin 3 squeezes the seal 4 so that the seal 4 is separated from the inner bladder skin 3, and exhaust occurs, thereby preventing the inner bladder from rupturing. A new seal 4 can be replaced and inflated for continued use.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
