Description

Technical Field

[0001] The utility model belongs to the technical field of pickle balls, and in particular relates to a multi-chamber shock-absorbing structure of the inner core of a pickle ball. Background Art

[0002] Pickleball is a racket-based sport that combines elements of badminton, tennis, and table tennis. The court is similar in size to a badminton court, with a net about the same height as a tennis net. The ball is a hollow plastic ball slightly larger than a tennis ball and has multiple holes. Playing is similar to tennis, with the ball either ground or intercepted mid-air. Pickleball is undoubtedly a fun and easy-to-learn game suitable for people of all ages.

[0003] However, there are some problems with the existing technology: the existing pickle ball does not have a shock-absorbing function. When people use the pickle ball, they often need to hit the pickle ball hard and the flying ball falls to the ground, but the pickle ball cannot offset the external impact force, which will cause the surface of the pickle ball to deform, resulting in damage to the pickle ball, affecting the service life of the pickle ball and increasing the cost of use. Therefore, we propose a multi-chamber shock-absorbing structure for the inner core of the pickle ball. Utility Model Content

[0004] In response to the problems existing in the prior art, the purpose of the present invention is to provide a multi-chamber shock-absorbing structure for the inner core of a pickle ball, which has the advantage of having a shock-absorbing function and solves the problem that the existing pickle ball does not have a shock-absorbing function. When people use the pickle ball, they often need to hit the pickle ball hard and the flying ball falls to the ground, but the pickle ball cannot offset the external impact force, which will cause the surface of the pickle ball to deform, resulting in damage to the pickle ball, affecting the service life of the pickle ball and increasing the cost of use.

[0023] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 6 As shown, the embodiment of the present invention provides a multi-chamber shock-absorbing structure of a pickle ball inner core, comprising:

[0025] The pickle ball body 1 has a shockproof chamber 2 disposed inside the pickle ball body 1 , a buffer chamber 3 is disposed around the inside of the shockproof chamber 2 , and a shock-absorbing chamber 4 is disposed inside the buffer chamber 3 .

[0026] Furthermore, the shockproof chamber 2 includes a polystyrene foam filling layer 21, a polyethylene foam filling layer 22 and a polyurethane foam filling layer 23. The surface of the polyurethane foam filling layer 23 is located inside the polyethylene foam filling layer 22, and the surface of the polyethylene foam filling layer 22 is located inside the polystyrene foam filling layer 21. Through the mutual cooperation of the internal thread interface 5 and the external thread interface 6, the upper hemisphere shell 11 and the lower hemisphere shell 12 are facilitated to be disassembled and assembled during use, thereby solving the problem that the upper hemisphere shell 11 and the lower hemisphere shell 12 are inconvenient to be disassembled and assembled during use.

[0027] Through the setting of the polystyrene foam filling layer 21, in which the polystyrene foam plastic is mainly made of polystyrene resin and added with additives such as foaming agent, it is the most commonly used cushioning material, it has a closed-cell structure, low water absorption, and excellent water resistance; low density, generally 0.015~0.03; good mechanical strength, excellent cushioning performance; good processability, easy molding; good colorability, strong temperature adaptability, through the setting of the polyethylene foam filling layer 22, in which the polyethylene foam plastic is mainly made of polyethylene resin and added with foaming agent, cross-linking agent and other additives, it is a very important cushioning material, it has low density, the minimum can reach 0.01g / cm3; cushioning, heat resistance, low water absorption; stable chemical properties, not susceptible to corrosion; good mechanical properties, toughness, flexibility, friction resistance and other advantages.

[0028] Furthermore, the buffer chamber 3 includes an elastic airbag 31, a nitrile rubber layer 32, and a polyamide fabric layer 33. The surface of the elastic airbag 31 is located inside the nitrile rubber layer 32, and the surface of the nitrile rubber layer 32 is located inside the polyamide fabric layer 33. Through the setting of the shockproof chamber 2, the shockproof performance of the pickle ball body 1 is increased during use, which solves the problem that the pickle ball body 1 is easily hit and falls during use, causing the pickle ball body 1 to be deformed and damaged due to the impact force, thereby increasing the service life of the pickle ball body 1.

[0029] The provision of the nitrile rubber layer 32 provides good protection for the elastic airbag 31 during use. Nitrile rubber is a copolymer formed by polymerization of acrylonitrile and butadiene monomers, and is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, and good heat resistance.

[0030] Furthermore, the shock-absorbing chamber 4 includes an EVA rubber and plastic foam core block 41 and a high-density EPDM rubber foam filling layer 42. The surface of the EVA rubber and plastic foam core block 41 is located inside the high-density EPDM rubber foam filling layer 42. Through the buffer chamber 3, it has a good buffering effect on the pickle ball body 1 during use, preventing the pickle ball body 1 from being unable to effectively buffer during use, resulting in hard damage to the pickle ball body 1, thereby increasing the service life of the pickle ball body 1.

[0031] Through the setting of the EVA rubber and plastic foam core block 41, the EVA rubber and plastic foam material is light and elastic, and has excellent shockproof performance. The EVA material is antibacterial, oil-resistant, acid-alkali-resistant and chemical-resistant, has a long service life, low density, excellent floating performance, does not absorb water, has good moisture-proof performance, and is resistant to low temperatures at -170°C to 105°C. It has the advantages of being non-toxic, odorless, and will not mold, insect-eaten, or rot.

[0032] Furthermore, the pickle ball body 1 includes an upper hemisphere shell 11 and a lower hemisphere shell 12. The lower end of the upper hemisphere shell 11 is fixedly connected to an internal threaded interface 5, and the upper end of the lower hemisphere shell 12 is fixedly connected to an external threaded interface 6 that is compatible with the internal threaded interface 5. Through the setting of the shock-absorbing chamber 4, the pickle ball body 1 has a good shock-absorbing effect during use, which solves the problem that the pickle ball body 1 cannot effectively absorb shock during use, affecting the stability of the pickle ball body 1.

[0033] By setting up a high-density EPDM rubber foam filling layer 42, the EPDM rubber foam material has good heat insulation and sound absorption properties due to its excellent weather resistance, heat resistance and ozone resistance, and can be used as a sound insulation pad and a sound-absorbing strip. Its open-pore structure can effectively absorb sound and reduce noise pollution, and plays an important role in sealing, cushioning, heat insulation, sound absorption, waterproofing and dustproofing.

[0034] Furthermore, the number of the buffer chambers 3 is six groups, and the six groups of buffer chambers 3 are arranged at equal distances on the surface of the shock absorbing chamber 4 .

[0035] The provision of the polyamide fabric layer 33 increases the safety of the elastic airbag 31 during use. The polyamide fabric has good crack resistance and can reduce the impact force of the elastic airbag 31 when it is inflated after vulcanization treatment.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
