Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] This invention provides a micro-particle ribbed cylindrical perforated anti-slip basketball. By evenly distributing ribs on the surface of the ball, the contact area between the ball and the palm is increased, thereby increasing friction and effectively preventing slippage. Please refer to [link / reference]. Figure 1 Includes: ball 100 and valve core assembly 200;

[0047] Example 1

[0048] Please see Figure 1-2 The vertical rib 110 is a hollow cylindrical vertical rib, which is integrally formed on the surface of the sphere 100. The vertical rib 110 is evenly distributed on the surface of the sphere 100. During use, the palm is always in contact with the vertical rib 110. The vertical rib 110 increases the friction between the palm and the surface of the sphere 100, thereby effectively playing a role in preventing slippage.

[0049] Example 2

[0050] Please see Figure 1 and Figure 3-8 The valve core assembly 200 is installed in the inner cavity of the ball 100. One end of the valve core assembly 200 penetrates the outer surface of the ball 100, is disposed on the outside of the ball 100 and is flush with the outer surface of the ball 100. The valve core assembly 200 can be used to inflate the inner cavity of the ball 100.

[0051] Valve core assembly 200 includes housing assembly 210, drive component 220, positioning mechanism 230 and sealing mechanism 240;

[0052] The housing assembly 210 is disposed in the inner cavity of the sphere 100. One end of the housing assembly 210 penetrates the outer surface of the sphere 100 and is disposed outside the sphere 100 and flush with the outer surface of the sphere 100. The inner cavity of the housing assembly 210 and the sphere 100 can be manually connected, and the inner cavity of the sphere 100 can be inflated after connection.

[0053] The driving component 220, the positioning mechanism 230, and the sealing mechanism 240 are all movably installed in the inner cavity of the housing assembly 210. The driving component 220 is movably connected to the positioning mechanism 230, and the sealing mechanism 240 is movably connected to the positioning mechanism 230. The driving component 220 drives the positioning mechanism 230 to move, and the positioning mechanism 230 drives the sealing mechanism 240 to move, so as to achieve the purpose of penetrating the inner cavity of the housing assembly 210 and the inner cavity of the ball 100, thereby achieving the purpose of inflating the inner cavity of the ball 100.

[0054] The housing assembly 210 includes a housing 210a, a sealing plug 210b, an air port 210c, and a first spring 210d;

[0055] The housing 210a is disposed in the inner cavity of the sphere 100. One end of the housing 210a penetrates the outer surface of the sphere 100 and is disposed outside the sphere 100 and flush with the outer surface of the sphere 100. The housing 210a and the sphere 100 are sealed together.

[0056] The sealing plug 210b is fixed to the end of the inner cavity of the housing 210a facing the outside of the sphere 100 by adhesive. The side of the sealing plug 210b is provided with an inflation hole that can accommodate the air nozzle. The air nozzle is inserted into the inner cavity of the housing 210a through the inflation hole.

[0057] The air inlet 210c is integrally formed in the middle of the outer circumferential wall of the shell 210a. The air inlet 210c is connected to the inner cavity of the shell 210a. The shell 210a is connected to the inner cavity of the sphere 100 through the air inlet 210c. Air is injected into the inner cavity of the shell 210a through the air nozzle. Air enters the inner cavity of the sphere 100 through the air inlet 210c.

[0058] One end of the first spring 210d is fixed to the end of the inner cavity of the housing 210a away from the sealing plug 210b. Under the action of external force, the first spring 210d can extend and retract within the inner cavity of the housing 210a.

[0059] The drive unit 220 includes a mounting ring 220a, a connecting block 220b, and a mounting plate 220c;

[0060] The mounting ring 220a is disposed in the inner cavity of the housing 210a near the sealing plug 210b. The outer circumferential wall of the mounting ring 220a contacts the inner circumferential wall of the housing 210a. The mounting ring 220a is movably connected to the housing 210a. The mounting ring 220a can move along the axial direction of the housing 210a in the inner cavity of the housing 210a.

[0061] A tapered hole 220a-1 is formed on the side of the mounting ring 220a facing the sealing plug 210b and passes through the end of the mounting ring 220a away from the sealing plug 210b;

[0062] The vent 220a-2 is integrally formed on the mounting ring 220a at the end away from the sealing plug 210b. The vent 220a-2 communicates with the inner cavity of the conical hole 220a-1. The air nozzle is inserted into the inner cavity of the conical hole 220a-1 through the air inlet on the sealing plug 210b. The end of the air nozzle inserted into the inner cavity of the conical hole 220a-1 contacts the conical surface of the conical hole 220a-1. The conical surface will not block the end of the air nozzle. Therefore, when inflating, air enters the conical hole 220a-1 through the air nozzle and is discharged into the inner cavity of the housing 210a through the vent 220a-2, and enters the inner cavity of the ball 100 through the air port 210c.

[0063] There are three connecting blocks 220b. The three connecting blocks 220b are integrally formed in an equilateral triangle on the edge of the mounting ring 220a away from the sealing plug 210b. The position of the three connecting blocks 220b should be such that they do not block the air port 210c assembly.

[0064] Mounting plate 220c is integrally formed on the end of connecting block 220b away from mounting ring 220a. The outer circumferential wall of mounting plate 220c contacts the inner circumferential wall of housing 210a. A pressure rod 220c-1 is integrally formed on the side of mounting plate 220c away from connecting block 220b. An external force can be applied to mounting ring 220a through an air nozzle to drive mounting ring 220a to move along the axial direction of housing 210a away from sealing plug 210b in the inner cavity of housing 210a. Mounting ring 220a drives mounting plate 220c to move away from sealing plug 210b through connecting block 220b, and drives pressure rod 220c-1 to move through mounting plate 220c.

[0065] The positioning mechanism 230 includes a movable shaft 230a, a second spring 230b, a limiting block 230c, and a third spring 230d;

[0066] The movable shaft 230a is located in the middle of the inner cavity of the housing 210a, corresponding to the air port 210c. The outer circumferential wall of the movable shaft 230a contacts the inner circumferential wall of the housing 210a. The movable shaft 230a is located between the mounting plate 220c and the first spring 210d. One end of the movable shaft 230a away from the mounting plate 220c is fixedly connected to the end of the first spring 210d. The movable shaft 230a is movably connected to the housing 210a and can move along the axial direction of the housing 210a within the inner cavity of the housing 210a.

[0067] The movable shaft 230a has a connecting hole 230a-1 that matches the pressure rod 220c-1 at one end facing the mounting plate 220c. The pressure rod 220c-1 can move along the axial direction of the connecting hole 230a-1 in the inner cavity of the connecting hole 230a-1 under the drive of the mounting plate 220c.

[0068] The movable shaft 230a has a connecting groove 230a-2 inside. The connecting groove 230a-2 is a rectangular groove. The inner cavity of the connecting groove 230a-2 communicates with the inner cavity of the connecting hole 230a-1. The end of the pressure rod 220c-1 away from the mounting plate 220c can be inserted into the inner cavity of the connecting groove 230a-2 through the connecting hole 230a-1.

[0069] The bottom of the movable shaft 230a is provided with a groove 230a-3, which is a cylindrical groove;

[0070] The bottom of the movable shaft 230a is provided with a mounting groove 230a-4. The mounting groove 230a-4 is located inside the recess 230a-3 and communicates with the inner cavity of the recess 230a-3. There are six mounting grooves 230a-4, with three mounting grooves 230a-4 on each of the left and right sides. The two adjacent mounting grooves 230a-4 are set at a 15° angle.

[0071] One end of the second spring 230b is fixed to the end of the inner cavity of the connecting groove 230a-2 away from the connecting hole 230a-1. The second spring 230b can extend and retract within the inner cavity of the connecting groove 230a-2 under the action of external force.

[0072] The limiting block 230c is disposed in the inner cavity of the connecting groove 230a-2 and connected to the end of the second spring 230b facing the connecting hole 230a-1. The limiting block 230c is movably connected to the connecting groove 230a-2 and can move along the length of the connecting groove 230a-2 in the inner cavity of the connecting groove 230a-2. Under the elastic force of the second spring 230b, the limiting block 230c contacts the side of the inner cavity of the connecting groove 230a-2 away from the second spring 230b. The limiting block 230c contacts the end of the pressure rod 220c-1 away from the mounting plate 220c. The pressure rod 220c-1 drives the limiting block 230c to move in the inner cavity of the connecting groove 230a-2 to compress the second spring 230b.

[0073] There are six third springs 230d, which are installed one-to-one in the inner cavity of the six mounting slots 230a-4;

[0074] The sealing mechanism 240 includes a sealing block 240a and a guide post 240b;

[0075] The guide post 240b is integrally formed at the top center of the sealing block 240a. The guide post 240b is inserted into the bottom of the movable shaft 230a and passes through the movable shaft 230a to be inserted into the inner cavity of the connecting groove 230a-2. The top plane of the guide post 240b contacts the bottom plane of the limiting block 230c. The height position of the guide post 240b is limited by the limiting block 230c. The top of the guide post 240b is provided with a second inclined surface 240b-1 that matches the first inclined surface 230c-1.

[0076] The sealing block 240a is set in the inner cavity of the air port 210c via the guide post 240b. The sealing block 240a is movably connected to the air port 210c. The sealing block 240a can move along the axial direction of the air port 210c in the inner cavity of the air port 210c. The sealing block 240a and the air port 210c provide a movable seal. The top edge of the sealing block 240a is fixedly connected to the end of the third spring 230d away from the mounting groove 230a-4. The sealing block 240a is inserted into the inner cavity of the air port 210c under the limit of the limiting block 230c. The third spring 230d is in a stretched state under the action of the sealing block 240a.

[0077] Specific;

[0078] In the sealed state: the mounting ring 220a is in contact with the sealing plug 210b on the side facing the sealing plug 210b, the pressure rod 220c-1 is inserted into the inner cavity of the connecting hole 230a-1, the second spring 230b is in a naturally extended state, and the limiting block 230c is pressed against the side wall of the inner cavity of the connecting groove 230a-2 away from the second spring 230b by the second spring 230b and in contact with the pressure rod 220c-1, the top plane of the guide post 240b is in contact with the bottom plane of the limiting block 230c, and the height position of the guide post 240b is limited, so that the sealing block 240a is inserted into the inner cavity of the air port 210c to seal it, and prevent the gas in the inner cavity of the ball 100 from entering the inner cavity of the housing 210a and causing air leakage. At this time, the third spring 230d is in a stretched state under the pull of the sealing block 240a, and the first spring 210d is in a naturally extended state.

[0079] During inflation: The air nozzle is inserted into the inner cavity of the conical hole 220a-1 through the inflation hole on the sealing plug 210b, contacting the conical surface of the inner cavity of the conical hole 220a-1. External force is applied to the conical hole 220a-1 through the air nozzle, driving the mounting ring 220a to move away from the sealing plug 210b. The mounting ring 220a drives the pressure rod 220c-1 to move into the inner cavity of the connecting groove 230a-2. The pressure rod 220c-1 drives the limiting block 230c to move, compressing the second spring 230b. This causes the bottom plane of the limiting block 230c to gradually move away from the top plane of the guide post 240b, bringing the first inclined surface 230c-1 into contact with the second inclined surface 240b-1, releasing the height restriction on the guide post 240b. Under the elastic force of the third spring 230d, the sealing block 240a moves toward the groove 230a-3, disengaging from the air port 210c and entering the inner cavity of the groove 230a-3. The top of the guide post 240b is inserted into the inner cavity of the connecting groove 230a-2, releasing the restriction on the movable shaft 230a. Under the external force applied by the air nozzle, the movable shaft 230a moves away from the sealing plug 210b, compressing the first spring 210d, causing the movable shaft 230a to move away from the air port 210c, thus releasing the blockage of the air port 210c. At this time, air is injected into the inner cavity of the housing 210a through the air nozzle. Air enters the interior of the sphere 100 through the housing 210a and the air port 210c, inflating the sphere 100.

[0080] Reset: After inflation, remove the air nozzle from the sealing plug 210b, releasing the external force applied to the tapered hole 220a-1. Under the elastic force of the first spring 210d, drive the movable shaft 230a to move towards one side of the sealing plug 210b until the movable shaft 230a moves to the air port 210c. Since the air nozzle has been removed, the external force applied to the limiting block 230c is also released. Under the elastic force of the second spring 230b, drive the limiting block 230c to move towards the connecting hole 230a-1. The moving drive first inclined surface 230c-1 applies pressure to the second inclined surface 240b-1, driving the guide column 240b to move towards the air port 210c. The guide column 240b drives the sealing block 240a into the inner cavity of the air port 210c to seal the air port 210c. Due to the limiting block 230c, even if the air pressure in the inner cavity of the ball 100 is high, it cannot drive the sealing block 240a to move upward, so that the sealing block 240a and the air port 210c are always in a sealed state, improving the sealing effect and reducing the possibility of air leakage.
