[0028] Embodiment 1
[0029] like Figure 1 As shown, it is a schematic diagram of the structure of a protective support structure of an explosion-proof basketball liner of the utility model, including an liner 1, and a first protective layer 2 is arranged on the outer surface of the liner 1. The first protective layer 2 includes a first rubber layer 201 and a first yarn winding layer 202 arranged on the outer side of the first rubber layer 201.
[0030] An airbag 3 is arranged outside the first protective layer 2 .
[0031] The outer surface of the airbag 3 is provided with a second protective layer 4 , which includes a foam rubber layer 401 , a second yarn winding layer 402 , a carbon fiber layer 403 and a second rubber layer 404 from the outside to the inside.
[0032] The first yarn winding layer 202 and the second yarn winding layer 402 have the same structure. The first yarn winding layer 202 includes a first nylon thread layer and a second nylon thread layer. The first nylon thread layer and the second nylon thread layer are perpendicular to each other and are wound in sequence. Nylon thread has the advantages of good wear resistance, heat resistance and good mechanical properties. It is used on the outer surface of the liner 1 and the airbag 3 to play an effective protective and supporting role.
[0033] The carbon fiber layer 403 has high strength and high toughness, and can play a protective role to prevent the airbag 3 from bursting.
[0034] The foam rubber layer 401 can be a natural foam rubber layer, an artificial foam rubber layer or an artificial-natural mixed foam rubber layer, and is not specifically limited. The foam rubber layer 401 can increase the elasticity and deformation resistance of the basketball liner, and the obtained finished product has good roundness and good feel.
[0035] The airbag 4 is evenly divided into a first air chamber 6, a second air chamber 7, a third air chamber 8 and a fourth air chamber 9 by four partition layers 5. Each air chamber is an independent space and can only be inflated and connected through a sealed explosion-proof component 13 provided on the partition layer 5.
[0036] The first gas bin 6 is provided with a gas bin inflation hole 10, and the top of the gas bin inflation hole 10 is provided with a first sealing cover to ensure the air tightness of the gas bin.
[0037] The sealed explosion-proof assembly 13 includes a cylinder 131 , a positioning cylinder 132 is arranged inside the cylinder 131 , a vent pipe 133 is installed inside the positioning cylinder 132 , an air plug 134 is arranged at the other end of the vent pipe 133 , a baffle 135 is fixedly connected to the other end of the air plug 134 , and the positioning cylinder 132 is fixedly connected to the baffle 135 .
[0038] There is a sliding structure between the positioning cylinder 132 and the cylinder body 131 .
[0039] When the air bin is inflated through the air bin charging hole 10, the gas enters each air bin in turn through the vent pipe 133. When the air pressure in the air bin reaches a certain level, the gas will push the baffle 135 to move toward the vent pipe 133, and the vent pipe 133 will be blocked by the air plug 134, thereby preventing bursting caused by excessive inflation.
[0040] An inner liner inflation hole 11 (not marked in the figure) is arranged on the outside of the foam rubber layer 401, and an inner liner inflation tube 12 is connected to the inside of the inner liner inflation hole 11. The inner liner inflation tube 12 runs through the fourth air chamber 9. The inner liner inflation tube 12 can also be connected to a sealing explosion-proof component 13 inside the inner liner. Its working principle is the same as that of the sealing explosion-proof component in the air chamber, which can prevent the inner liner 1 from bursting.
[0041] A second sealing cover is arranged outside the inner liner inflation hole 11 to ensure the air tightness of the inner liner 1 .
[0042] Therefore, the utility model adopts the above-mentioned protection support structure of the explosion-proof basketball liner, which can effectively protect the basketball liner, making the liner less likely to deform, and is provided with a sealed explosion-proof component to increase the service life of the basketball.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
