[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] Please see Figures 1 to 4 The present invention provides a sprocket with easy tooth replacement, comprising a sprocket 1, a side groove 11, a top hole assembly 12, a tooth assembly 2, and a fixing assembly 3;

[0023] Multiple side grooves 11 are formed on the side wall of the sprocket 1. Multiple top hole groups 12 correspond one-to-one with the teeth of the multiple sprockets 1. Each top hole group 12 has two top holes, and both top holes are formed at the top of the teeth of the sprocket 1. The gear tooth assembly 2 is mounted on the sprocket 1. Multiple fixing components 3 are provided, and each fixing component 3 corresponds one-to-one with the multiple top holes. The fixing components 3 are mounted at the bottom of the top holes.

[0024] Among them, the side groove 11 on the sprocket 1 and the top hole in the top hole group 12 serve to connect and assemble, and the gear assembly 2 and the fixing assembly 3 are both installed on the side groove 11 and the top hole;

[0025] Meanwhile, the gear assembly 2 is more firmly fixed to the sprocket 1 through the fixing assembly 3, thereby improving the connection strength of the sprocket 1 and thus improving the working stability of the sprocket 1.

[0026] In this embodiment, two limiting grooves are provided inside the top hole.

[0027] The two limiting grooves inside the top hole are used to cooperate with the gear assembly 2 to achieve quick assembly and disassembly.

[0028] In this embodiment, the toothed plate 21 is mounted on the sprocket 1, the tooth tops 22 are provided with a plurality of teeth and are respectively mounted on both ends of the toothed plate 21, and the tooth roots 23 are provided with a plurality of teeth and are respectively mounted on both sides of the toothed plate 21.

[0029] The tooth tip 22 is mainly used to fix the tooth tip of the sprocket 1, and the tooth tip 22 is installed at the top hole. The tooth root 23 is mainly used to fix the tooth root of the sprocket 1, and the tooth root 23 is installed at the side groove 11. By using the tooth tip 22 and tooth root 23 to be connected and fixed to the sprocket 1 respectively, the connection strength of the sprocket 1 is improved, thereby improving the working stability of the sprocket 1.

[0030] In this embodiment, multiple sliding rods 221 are respectively passed through both ends of the gear plate 21. Multiple positioning pieces 222 correspond one-to-one with the multiple sliding rods 221 and are installed at the top of the sliding rods 221. Multiple handles 223 correspond one-to-one with the multiple positioning pieces 222 and are installed at the top of the positioning pieces 222. Multiple limiting piece groups 224 correspond one-to-one with the multiple sliding rods 221. Each limiting piece group 224 contains two limiting pieces, which are respectively installed at the bottom end of the sliding rods 221. Multiple limiting spring groups 225 correspond one-to-one with the multiple limiting piece groups 224. Each limiting spring group 225 contains two limiting springs, one end of which is connected to the limiting piece, and the other end is connected to the sliding rod 221.

[0031] The positioning piece 222 is marked, and the installation direction of the limiting piece is consistent with the direction of the marking on the positioning piece 222;

[0032] Simultaneously, during the installation of the tooth tip 22, the two sliding rods 221 on the gear plate 21 need to be aligned with the two top holes on the sprocket 1. Then, by manually rotating the handle 223, the sliding rods 221 rotate accordingly, making the marked side of the positioning piece 222 horizontal with the direction of the limiting groove in the top hole. Then, the gear plate 21 and the tooth tip 22 are pushed towards the sprocket 1. During the process of the sliding rod 221 extending into the top hole, because the diameter of the top hole is smaller than the unfolded diameter of the limiting piece, the limiting spring pulls the limiting piece inward, allowing the sliding rod 221 to continue moving down along the inner wall of the top hole. When the bottom end of the sliding rod 221 contacts the fixing component 3, it stops moving down. At this time, the limiting piece moves into the limiting groove in the top hole, and the limiting spring resets, causing the limiting piece to be in the limiting position. The groove is unfolded. At this time, the positioning piece 222 installed at the top of the slide rod 221 slides into the gear tooth plate 21, thereby achieving the purpose of installing the tooth top 22. Conversely, during the process of disassembling the tooth top 22, the slide rod 221 is pushed down along the inner diameter of the top hole. When the thrust is large enough, the slide rod 221 will cause the fixing component 3 to retract. As the slide rod 221 moves down and the fixing component 3 retracts, the limiting piece moves out of the limiting groove. Then, the handle 223 is manually rotated so that the side of the positioning piece 222 with the mark is perpendicular to the direction of the limiting groove in the top hole. The limiting piece also rotates with the positioning piece 222, so that it cannot enter the limiting groove during the upward movement. Then, the handle 223 is pulled so that the slide rod 221 moves up along the inner wall of the top hole and out of the top hole, thereby achieving the purpose of disassembling the tooth top 22.

[0033] In this embodiment, a plurality of rotating shafts 231 are respectively installed on both sides of the gear plate 21, a plurality of connecting flexible plates 232 correspond one-to-one with the plurality of rotating shafts 231, and one end of the connecting flexible plate 232 is connected to the rotating shaft 231, a plurality of magnetic plates 233 correspond one-to-one with the plurality of connecting flexible plates 232, and the other end of the magnetic plate 233 is connected to the connecting flexible plate 232.

[0034] During the installation of the tooth root 23, after the tooth plate 21 is fully engaged with the sprocket 1, the rotating shafts 231 on both sides of the tooth plate 21 need to be manually rotated so that the two connecting flexible plates 232 on the two rotating shafts 231 pass through the side grooves 11 on the sprocket 1. At this time, the magnetic plates 233 on the connecting flexible plates 232 attract and adhere to each other, thereby achieving the purpose of installing the tooth root 23. Conversely, during the disassembly of the tooth root 23, the magnetic plates 233 on the two connecting flexible plates 232 need to be manually separated, and then the two connecting flexible plates 232 are pulled out of the side grooves 11, thereby achieving the purpose of disassembling the tooth root 23. This improves the connection strength between the tooth root 23 and the sprocket 1, and also increases the speed of tooth assembly and disassembly.

[0035] In this embodiment, a plurality of fixing springs 31 correspond one-to-one with a plurality of top holes, and one end of each fixing spring 31 is installed inside the top hole. A plurality of fixing plates 32 correspond one-to-one with a plurality of fixing springs 31, and the fixing plates 32 are installed at the other end of each fixing spring 31.

[0036] During the disassembly of the tooth top 22, the operator continues to apply a downward pushing force to the positioning plate 222, causing the slide bar 221 to continue to move downward. When the pushing force exceeds the bearing capacity of the fixed spring 31, the fixed spring 31 contracts and drives the fixed plate 32 to move downward. At this time, the limiting plate on the slide bar 221 moves out of the limiting groove. Then, the operator rotates the handle 223 so that the side of the positioning plate 222 with the mark is perpendicular to the direction of the limiting groove in the top hole. The limiting plate also rotates with the positioning plate 222, thus preventing it from entering the limiting groove during the upward movement. Then, the operator pulls the handle 223 to move the slide bar 221 out of the top hole along the inner wall of the top hole. This greatly improves the connection strength between the tooth top 22 and the sprocket 1 through the fixing component 3, and also increases the disassembly speed of the gear teeth.

[0037] In summary, the sprocket with easily replaceable teeth includes a sprocket 1, a tooth assembly 2 for quick disassembly, and a fixing assembly 3 for engaging and fixing the tooth assembly 2. The sprocket 1 includes multiple side grooves 11 and multiple top hole groups 12. The multiple side grooves 11 are all formed on the side wall of the sprocket 1. The multiple top hole groups 12 correspond one-to-one with the teeth of the multiple sprocket 1 teeth. Each top hole group 12 has two top holes, and both top holes are formed at the top of the teeth of the sprocket 1 teeth. The tooth assembly 2 is mounted on the sprocket 1. Multiple fixing assemblies 3 are provided, and the multiple fixing assemblies 3 engage with multiple... The top holes correspond one-to-one, and the fixing component 3 is installed at the bottom of the top hole. The sprocket of this utility model, which facilitates tooth replacement, allows the teeth to be quickly installed and removed from the sprocket 1 through the tooth assembly 2. This reduces the wear and maintenance costs of the sprocket 1 and improves work efficiency. At the same time, the tooth tip 22 and tooth root 23 work together with the fixing component 3 to connect and fix the tooth root and tooth tip to the sprocket 1, which can be more firmly fixed to the sprocket 1. This also improves the speed of tooth installation and removal, thereby improving the connection strength of the sprocket 1 and thus improving the working stability of the sprocket 1.
