Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 A quick-change structure for a bucket for a loader includes a connecting frame 1 and a bucket body 2. An installation structure for installing the bucket body 2 is provided on the inner side of the connecting frame 1.

[0024] like Figure 1 As shown, the mounting structure includes two inner frames 3 fixedly connected to the inner side of the connecting frame 1, a threaded rod 4 rotatably connected to the inner side of the inner frame 3, a sleeve 5 fixedly connected to the other end of the threaded rod 4 and a sleeve rod 6 passing through the inner side of the sleeve 5, a threaded block 7 threadedly connected to the outer side of the threaded rod 4, and an insert block 8 fixedly connected to one side of the threaded block 7.

[0025] It should be noted that a fixing block 9 is fixedly connected to the top of the bucket body 2, and a fixing opening matched with the fixing block 9 is opened at the bottom of the connecting frame 1, the fixing block 9 extends to the inner side of the connecting frame 1 through the fixing opening, and the left and right walls of the fixing block 9 are both provided with slots matched with the insertion block 8, the upper surface of the inner frame 3 is fixedly connected to the inner top wall of the connecting frame 1, the bottom of the inner frame 3 is fixedly connected to the inner bottom wall of the connecting frame 1, and the two inner frames 3 are respectively located on the left and right sides of the fixing block 9.

[0026] The left-side threaded rod 4 is rotatably connected to the inner right side wall of the left inner frame 3, and the left end of the left-side threaded rod 4 sequentially penetrates the right side wall of the corresponding threaded block 7, the left side wall of the corresponding threaded block 7 and the inner left side wall of the left inner frame 3 and is fixedly connected to the corresponding sleeve 5. The right-side threaded rod 4 is rotatably connected to the inner left side wall of the right inner frame 3, and the right end of the right-side threaded rod 4 sequentially penetrates the left side wall of the corresponding threaded block 7, the right side wall of the corresponding threaded block 7 and the inner right side wall of the right inner frame 3 and is fixedly connected to the corresponding sleeve 5.

[0027] The threaded block 7 is rectangular, and the height and width of the threaded block 7 are respectively equal to the height and width of the inside of the inner frame 3, so that the threaded block 7 can be moved by using the threaded thrust of the threaded rod 4. There are two left-side plug-in blocks 8, which are fixedly connected to the right side wall of the left-side threaded block 7, and there are two right-side plug-in blocks 8, which are fixedly connected to the left side wall of the right-side threaded block 7.
