[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0024] See attached document Figure 1 - Appendix Figure 4 As shown, a bucket tooth structure that is easy to assemble and disassemble includes a tooth part 1, a fixing part 2, a plug rod 3, and a plug-in part 4; wherein, the tooth part 1 is inserted into the fixing part 2 welded to the bucket from the front, and is inserted into the fixing part 2 from the side, and the end of the plug rod 3 extends to the outside of the fixing part 2 and is inserted into the plug-in part 4, thereby fixing the position of the tooth part 1.

[0025] In the specific implementation of this utility model, the toothed part 1 is the part that directly contacts and applies pressure to the object being excavated. It is inserted from the front into the fixing part 2 welded to the bucket, thus initially determining the position of the toothed part on the bucket and providing a foundation for subsequent fixing. Subsequently, the insert rod 3 is inserted from the side into the fixing part 2 and engages with the toothed part 1. This step fixes the toothed part 1, preventing it from moving or shaking in the front-to-back direction during excavation. The insert rod 3 also plays a role in lateral fixation, connecting the toothed part 1 and the fixing part 2 more tightly together. Finally, the insert part 4 is inserted into the end of the insert rod 3 that extends to the side of the fixing part 2 to lock the insert rod 3, preventing it from loosening or coming out during use. In this way, a stable connection structure is formed, allowing the toothed part 1 to be firmly fixed to the bucket and withstand various forces during the excavation process.

[0026] For the above scheme, please refer to the appendix. Figure 4 As shown, the tooth part 1 includes a tooth body 11 and a post 12; the end of the tooth body 11 is welded to the post 12, the post 12 has a rectangular structure and a through hole 121 for inserting the rod 3, and after the post 12 is inserted into the fixing part 2, the tooth body 11 contacts the end face of the fixing part 2.

[0027] In this design, the tooth body 11 is the part that directly participates in the excavation work. Its end is welded to the insert post 12 to form a whole. This connection method ensures that when the tooth body 11 is subjected to huge pressure and impact during operation, the insert post 12 inserts into the fixing part 2, so that the tooth body 11 can be accurately positioned on the bucket as required. Furthermore, the cooperation between the insert post 12 and the fixing part 2 restricts the movement of the tooth in all directions, allowing it to function only in the excavation direction. At the same time, the tooth body 11 contacts the end face of the fixing part 2, which not only further restricts the axial movement of the tooth body 11, but also allows the excavation force to be effectively transmitted to the fixing part 2 and the bucket through the tooth body 11, ensuring the efficiency of force transmission. The through hole 121 opened on the insert post 12 is used to insert the insert rod 3. After the insert rod 3 is inserted, the insert post 12 and the fixing part 2 are locked in the lateral direction to prevent the tooth from being displaced due to lateral force during excavation.

[0028] For the above scheme, please refer to the appendix. Figure 4 As shown, the fixing part 2 includes a fixing shell 21, a spring 22, a movable seat 23, and a limiting ring 24. The fixing shell 21 has a rectangular structure and is welded to the bucket. A through hole 211 for inserting the insertion rod 3 is opened on its side. The through hole 211 is connected to the movable seat 23, which is slidably disposed in the fixing shell 21, through the spring 22. A limiting ring 24 is fixedly disposed behind the movable seat 23 so that when the insertion rod 12 is inserted into the fixing shell 21 and the movable seat 23 abuts against the limiting ring 24, the through hole 211 and the through hole 121 are coaxial.

[0029] In this design, the fixed shell 21 is welded to the bucket, providing a stable installation base for the entire fixed part 2 and ensuring a firm connection with the bucket. Spring 22 is connected between the fixed shell 21 and the movable seat 23. The movable seat 23 can slide inside the fixed shell 21. When there is no external force, spring 22 is in its natural state or has a certain preload. When the insert 12 is inserted into the fixed shell 21, the insert 12 will push the movable seat 23 to move backward until the movable seat 23 abuts against the limiting ring 24. At this time, the through hole 211 and the through hole 121 on the insert 12 are coaxial, which allows the insertion rod 3 to be inserted and the teeth to be fixed. In this state, spring 22 is compressed, and the elastic force of spring 22 will generate a reaction force, so that the movable seat 23 always has a forward tendency, thus tightly abutting against the insert 12 and providing a stable support force for the insert 12, ensuring that the teeth will not be affected by shaking during operation.

[0030] For the above scheme, please refer to the appendix. Figure 4 As shown, the insertion rod 3 passes through the through hole 211 and the through hole 121 and extends to the outside of the fixing shell 21, and the end of the insertion rod 3 is provided with an insertion hole 31 for inserting the plug part 4.

[0031] In this design, the insertion rod 3 passes through the through hole 211 and the through hole 121, which allows the insertion rod 3 to be accurately positioned and connected on the fixed shell 21. This ensures that the insertion rod 3 can only be inserted along a specific path, guaranteeing the accuracy of the installation position of the insertion rod 3. This provides a basis for subsequent cooperation with the plug-in part 4. When the insertion rod 3 extends to the outside of the fixed shell 21, it can be easily docked with the external plug-in part 4.

[0032] For the above scheme, please refer to the appendix. Figure 4 As shown, in one embodiment, the insertion part includes an inner hole seat, a insertion shaft, a stop seat, and a second spring; the inner hole seat is welded to the side of the fixed shell and the insertion shaft for insertion into the insertion hole is movably disposed therein, the stop seat is welded on the insertion shaft, and a second spring is provided between the stop seat and the inner hole seat and sleeved on the outside of the insertion shaft, so that when the insertion shaft is pulled back, the second spring can give the stop seat a reaction force.

[0033] In this design, the inner hole seat is welded to the side of the fixed shell, providing a fixed support point for the entire insertion part and ensuring a stable connection between the insertion part and the fixed shell. When the insertion shaft is pulled back, the second spring is compressed, and the second spring will generate a reaction force to try to restore the insertion shaft to its initial position. This reaction force allows the insertion shaft to automatically reset when no external force is applied, ensuring that the insertion shaft can be accurately inserted into the insertion hole of the insertion rod again, thereby fixing the insertion rod.

[0034] For the above scheme, please refer to the appendix. Figure 5 As shown, in another embodiment, the insert part is a cotter pin, which is inserted into the socket.

[0035] In this design, the size and shape of the cotter pin are designed to match the socket, allowing it to be smoothly inserted into the socket. When the cotter pin is inserted into the socket, due to its structural characteristics, it will form a certain fastening force in the socket, thereby connecting and fixing the plug rod with other related components, preventing relative movement or separation between them.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
