Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Please refer to Figures 1 to 10 As shown:

[0042] The present invention provides a sprayer for external protection of sports equipment, comprising a driving motor 2, which is fixedly mounted at the bottom of a mounting seat 1; and further comprising a spray ring 3 and a liquid supply mechanism 4, wherein the spray ring 3 is rotatably connected to the top of the mounting seat 1, and the spray ring 3 and the mounting seat 1 are both of an unclosed ring body design, the driving motor 2 and the spray ring 3 are connected via a gear rack transmission, and two driving motors 2 are provided, and the two driving motors 2 are symmetrically arranged at the bottom of the mounting seat 1, and the spray ring 3 and the mounting seat 1 are both of an unclosed ring design, so that the tubular sports equipment accessories can be inserted from any position through the notch position of the spray ring 3 and the mounting seat 1, which is convenient for subsequent spraying operations;

[0043] There are two groups of liquid supply mechanisms 4, and the two groups of liquid supply mechanisms 4 are respectively arranged on both sides of the spray ring 3. The liquid supply mechanism 4 includes a liquid supply seat 401, an opening and closing valve ball 402, an opening and closing control block 403, a control gear 404 and a leak-proof sealing block 405. The liquid supply seat 401 is fixedly installed on the top of the mounting seat 1, and the opening and closing valve ball 402 is rotatably connected to the inside of the spray ring 3, the opening and closing control block 403 is plugged into the inside of the liquid supply seat 401, and the control gear 404 is rotatably connected to the inside of the liquid supply seat 401, and the leak-proof sealing block 405 is plugged into the side of the liquid supply seat 401. Each group of liquid supply mechanisms 4 is provided with two leak-proof sealing blocks 405, and the two leak-proof sealing blocks 405 are symmetrically arranged on both sides of the liquid supply seat 401;

[0044] The driving motor 2 can drive the spray ring 3 to rotate via the gear rack, and the liquid supply mechanism 4 can introduce the anti-rust paint and other protective materials supplied by the liquid supply device into the interior of the spray ring 3, so that the spray ring 3 can perform spray processing operations on the outside of the sports equipment accessories through the spray nozzle 5 when rotating. At the same time, with the coordinated use of two driving motors 2 and two groups of liquid supply mechanisms 4 (there is always at least one driving motor 2 and one group of liquid supply mechanisms 4 connected to the spray ring 3), the spray ring 3 can continuously obtain the transmission force and the supply of protective materials such as anti-rust paint, and is stable to use.

[0045] In the embodiment of the present disclosure, a spray channel 301 is provided inside the spray ring 3, and a spray nozzle 5 is installed on the inner side of the spray ring 3, and the spray nozzle 5 is connected to the spray channel 301. A plurality of liquid inlet channels 302 arranged in an annular manner are provided on the outer side of the spray ring 3, and a liquid inlet one-way valve is provided inside the liquid inlet channel 302. A liquid supply channel 4011 is provided inside the liquid supply seat 401, and the liquid supply channel 4011 is arranged on the rotation path of the liquid inlet channel 302. The liquid supply channel 4011 can be connected to up to three liquid inlet channels 302 at the same time, and the other side of the liquid supply channel 4011 is connected to the liquid supply device through a pipeline. In use, the liquid supply mechanism 4 can realize the function of automatic opening and closing according to the rotation position of the spray ring 3, so as to effectively avoid the leakage of protective materials such as anti-rust paint in the liquid supply mechanism 4 when the notch of the spray ring 3 moves to the corresponding position of the liquid supply mechanism 4. The use is stable and the top spring 40 is resisted. 31, the opening and closing control block 403 will abut against the abutment ring 303 when the spray ring 3 rotates. At this time, the opening and closing control block 403 can open the opening and closing valve ball 402. When the opening and closing valve ball 402 is opened, the anti-rust paint and other protective materials of the liquid supply equipment can enter the interior of the liquid supply channel 4011. As the spray ring 3 rotates, the liquid inlet channel 302 can overlap with the liquid supply channel 4011 alternately, so that these anti-rust paints can enter the interior of the spray channel 301 through the liquid inlet channel 302, and finally be sprayed out from the spray nozzle 5 to realize the spraying processing operation of the tubular sports equipment accessories. Since a liquid inlet one-way valve is arranged inside the liquid inlet channel 302, only the liquid inlet channel 302 that overlaps with the liquid supply channel 4011 will obtain the supply of protective materials such as anti-rust paint, and the liquid inlet channel 302 that does not overlap with the liquid supply channel 4011 will automatically close, and there will be no leakage, which is stable to use.

[0046] In the embodiment of the present disclosure, the opening and closing valve ball 402 can control the opening and closing of the liquid supply channel 4011, and a linkage gear 4021 is provided at one end of the valve stem of the opening and closing valve ball 402, and the gear teeth of the linkage gear 4021 and the control gear 404 are engaged for transmission. A resistance spring 4031 is provided inside the opening and closing control block 403, and the two ends of the resistance spring 4031 are respectively against the inside of the opening and closing control block 403 and the inside of the liquid supply seat 401. Under the action of the resistance spring 4031, the opening and closing control block 403 can be against the resistance ring 303 when the spray ring 3 rotates. The opening and closing control block 403 is arranged on the side of the liquid supply seat 401 facing the spray ring 3 when rotating. In use, when the notch portion of the spray ring 3 rotates to the vicinity of the liquid supply mechanism 4, the group of liquid supply mechanisms 4 can be closed to avoid leakage of materials. Since the opening and closing control block 403 is arranged on the side of the liquid supply seat 401 facing the spray ring 3 when rotating, when the notch portion of the spray ring 3 When just passing through the opening and closing control block 403, under the action of the resistance top spring 4031, the group of liquid supply mechanism 4 can be quickly and automatically closed to avoid material leakage. When the notch part of the spray ring 3 just passes through the opening and closing control block 403, the opening and closing control block 403 will lose the resistance to the resistance ring 303, so that the opening and closing control block 403 will move under the action of the resistance top spring 4031. The outside of the opening and closing control block 403 is provided with a spiral control groove 4032, and the inside of the control gear 404 is provided with a control protrusion 4041, and the control protrusion 4041 is inserted into the inside of the control groove 4032. When the opening and closing control block 403 moves, the control groove 4032 can drive the control gear 404 to rotate through the control protrusion 4041. When the control gear 404 rotates, it can drive the opening and closing valve ball 402 to rotate through the linkage gear 4021, thereby closing the liquid supply channel 4011 to avoid leakage of protective materials such as anti-rust paint, and stable use.

[0047] In the embodiment of the present disclosure, a resistance ring 303 is provided on the outside of the spray ring 3, and an avoidance inclined plate 3031 is provided at one end of the resistance ring 303 in the rotation direction, and the avoidance inclined plate 3031 is at least spaced apart by three liquid inlet channels 302 in front of the rotation direction. In use, when the notch position of the spray ring 3 completely passes through the liquid supply mechanism 4, the liquid supply mechanism 4 will automatically open, thereby supplying protective materials such as anti-rust paint to the spray ring 3 again. Since the opening and closing control block 403 is arranged on the side of the liquid supply seat 401 facing the spray ring 3 when rotating, When the spray ring 3 passes through the liquid supply mechanism 4 again, the avoidance inclined plate 3031 of the resistance ring 303 can lift and reset the opening and closing control block 403 again, so that the opening and closing valve ball 402 is switched to the open state, and the avoidance inclined plate 3031 is spaced at least three liquid inlet channels 302 in front of the rotation direction. That is to say, before the opening and closing valve ball 402 is opened again, the front end of the spray ring 3 can completely block the liquid supply channel 4011, which can effectively avoid the occurrence of protective materials such as anti-rust paint during use, and has extremely strong stability.

[0048] In the disclosed embodiment, the outer diameter of the leak-proof sealing block 405 is larger than the outer diameter of the liquid inlet channel 302, and a sealing top spring 4051 is provided on the outside of the leak-proof sealing block 405, and the two ends of the sealing top spring 4051 respectively abut against the inside of the leak-proof sealing block 405 and the inside of the liquid supply seat 401. In use, the liquid supply mechanism 4 can also ensure the sealing state when the spray ring 3 is used for normal feeding. Under the action of the sealing top spring 4051, the leak-proof sealing block 405 will abut against the outside of the spray ring 3, and the outer diameter of the leak-proof sealing block 405 is larger than the outer diameter of the liquid inlet channel 302, so that the leak-proof sealing block 405 will block the liquid inlet channel 302 that passes through and does not completely overlap with the liquid supply channel 4011, thereby avoiding the phenomenon that the liquid inlet channel 302 is simultaneously connected to the liquid supply channel 4011 and the outside of the liquid supply seat 401 to cause leakage, thereby further improving the stability of the device.

[0049] Specific usage and function of this embodiment: In the present invention, when spraying anti-rust paint and other protective materials on tubular sports equipment accessories, the spray ring 3 and the mounting seat 1 are both non-closed annular designs, and the spray ring 3 and the mounting seat 1 can be inserted from any position of the tubular sports equipment accessories through the notch position, and the spraying operation can be started. The driving motor 2 can drive the spray ring 3 to rotate through the gear rack, and the liquid supply mechanism 4 can introduce the anti-rust paint and other protective materials supplied by the liquid supply device into the interior of the spray ring 3, so that the spray ring 3 can perform spray processing operations on the outside of the sports equipment accessories through the spray nozzle 5 during rotation. At the same time, under the coordinated use of two driving motors 2 and two groups of liquid supply mechanisms 4 (there is always at least one driving motor 2 and one group of liquid supply mechanisms 4 and the spray The spray ring 3 is connected with the coating ring 3), the coating ring 3 can continuously obtain the transmission force and the supply of protective materials such as anti-rust paint, and the liquid supply mechanism 4 can realize the automatic opening and closing function according to the rotation position of the spray ring 3, so as to effectively avoid the leakage of protective materials such as anti-rust paint in the liquid supply mechanism 4 when the notch part of the spray ring 3 moves to the corresponding position of the liquid supply mechanism 4. It is stable to use, and under the action of the resistance top spring 4031, the opening and closing control block 403 will resist on the resistance ring 303 when the spray ring 3 rotates. At this time, the opening and closing control block 403 can open the opening and closing valve ball 402. When the opening and closing valve ball 402 is opened, the anti-rust paint and other protective materials of the liquid supply equipment can enter the interior of the liquid supply channel 4011. As the spray ring 3 rotates, the liquid inlet channel 302 can 4011, so that the anti-rust paint can enter the interior of the spray channel 301 through the liquid inlet channel 302, and finally be sprayed out from the spray nozzle 5 to realize the spray processing operation of the tubular sports equipment accessories. Since the liquid inlet channel 302 is provided with a liquid inlet one-way valve, only the liquid inlet channel 302 that overlaps with the liquid supply channel 4011 will obtain the supply of protective materials such as anti-rust paint, and the liquid inlet channel 302 that does not overlap with the liquid supply channel 4011 will automatically close without leakage. When the notch of the spray ring 3 rotates to the vicinity of the liquid supply mechanism 4, the group of liquid supply mechanisms 4 can be closed to avoid leakage of materials. Since the opening and closing control block 403 is arranged on the liquid supply seat 401 toward the spray ring 3 when it rotates, On one side, so when the notch of the spray ring 3 just passes through the opening and closing control block 403, under the action of the resistance top spring 4031, the group of liquid supply mechanism 4 can be quickly and automatically closed to avoid material leakage. When the notch of the spray ring 3 just passes through the opening and closing control block 403, the opening and closing control block 403 will lose the resistance to the resistance ring 303, so that the opening and closing control block 403 will move under the action of the resistance top spring 4031. When the opening and closing control block 403 moves, the control groove 4032 can drive the control gear 404 to rotate through the control protrusion 4041. When the control gear 404 rotates, it can drive the opening and closing valve ball 402 to rotate through the linkage gear 4021, thereby closing the liquid supply channel 4011 to avoid leakage of protective materials such as anti-rust paint.When the notch position of the spray ring 3 completely passes through the liquid supply mechanism 4, the liquid supply mechanism 4 will automatically open, thereby supplying anti-rust paint and other protective materials to the spray ring 3 again. Since the opening and closing control block 403 is arranged on the side of the liquid supply seat 401 facing the spray ring 3 when rotating, when the spray ring 3 passes through the liquid supply mechanism 4 again, the avoidance inclined plate 3031 of the resistance ring 303 can lift the opening and closing control block 403 again to reset, so that the opening and closing valve ball 402 is switched to the open state, and the avoidance inclined plate 3031 is at least spaced three liquid inlet channels 302 in front of the rotation direction, that is to say, before the opening and closing valve ball 402 is opened again, the spray ring 3 can move forward The end can completely block the liquid supply channel 4011, which can effectively avoid the occurrence of protective materials such as anti-rust paint during use. The liquid supply mechanism 4 can also ensure the sealing state when the spray ring 3 is used for normal feeding. Under the action of the sealing top spring 4051, the leak-proof sealing block 405 will contact the outside of the spray ring 3, and the outer diameter of the leak-proof sealing block 405 is larger than the outer diameter of the liquid inlet channel 302, so that the leak-proof sealing block 405 will block the liquid inlet channel 302 that passes through and does not completely overlap with the liquid supply channel 4011, avoiding the phenomenon that the liquid inlet channel 302 is simultaneously connected to the liquid supply channel 4011 and the outside of the liquid supply seat 401, causing leakage.
