DETAILED DESCRIPTION

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] A high-strength bucket tooth design, such as Figures 1-4 As shown, it consists of a tooth tip 1 and a tooth base 2. The tooth tip 1 has a built-in slot 11, while the tooth base 2 is equipped with a pluggable plug 21 that matches the slot 11. The plug 21 has a through groove 22 inside, and the tooth tip 1 has corresponding openings 12. The diameter of these openings 12 is slightly larger than that of the through groove 22 to accommodate the sliding of the positioning pin 31. One end of the positioning pin 31 is embedded in one opening 12, and the other end has a thread 312 for connecting to the connecting component 3 located at another opening 12. The plug 21 also has a cavity 23 inside, which is connected to the end face of the plug 21 and the through groove 22. A reinforcing component 4 is configured inside the cavity. When the positioning pin 31 slides into the through groove 22, it will drive the reinforcing component 4, thereby effectively increasing the contact area between the tooth tip 1 and the tooth base 2 and enhancing the stability of the connection.

[0023] When installing the bucket teeth, the worker first aligns the tooth tip 1 with the insert 21 and inserts it. Then, the positioning bolt 31 passes through the corresponding opening 12 and through slot 22 to firmly connect the tooth tip 1 with the tooth base 2. During this process, the positioning bolt 31 not only plays a connecting role, but also activates the reinforcing component 4 through its movement, further stabilizing the connection between the tooth tip 1 and the tooth base 2, effectively preventing shaking after installation.

[0024] Practical effect: By inserting the positioning bolt 31 into the through slot 22, the reinforcing component 4 is moved, thereby increasing the engagement area between the tooth tip 1 and the tooth base 2, ensuring the connection stability between the tooth tip 1 and the tooth base 2.

[0025] like Figure 5 As shown, the end of the positioning bolt 31 away from the thread 312 is provided with a hexagonal groove 311. The connecting component 3 includes a washer 32 and a locking member 33. The washer 32 is sleeved on the positioning bolt 31. The two sides of the washer 32 abut against the positioning bolt 31 and the toothed seat 2 respectively. The locking member 33 matches the thread 312. The hexagonal groove 311 facilitates the selection of the connection between the positioning bolt 31 and the locking member 33.

[0026] like Figure 6As shown, the reinforcing assembly 4 comprises a column 41 and a sliding block 42, the column 41 is provided with a round groove 411 for the sliding block 42 to slide into, when the column 41 slides in the cavity 23, the sliding block 42 will be pushed to extend outward until it matches the clamping part of the tooth tip 1, the spring 43 is arranged between the column 41 and the plug-in 21, the spring 43 is used to push the column 41 out of the cavity 23 in the direction of the through groove 22, the tooth tip 1 is provided with a positioning groove 13 at the position corresponding to the position of the sliding block 42, when the sliding block 42 is pushed out, it can accurately abut with the positioning groove 13.

[0027] The reinforcing assembly 4 is arranged so that when the connecting assembly 3 slides into the through groove 22, the sliding block 42 can be pushed out of the cavity 23 and abut with the positioning groove 13 in the tooth gap, and the tooth tip 1 is pressed, the tooth tip 1 is prevented from shaking by pressing, the stability of the connection between the tooth tip 1 and the tooth seat 2 is increased, and the tooth is more practical.
