DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0021] Embodiment:

[0022] Referring to Figures 1-3 A balance weight structure for electric loader, comprising:

[0023] The main body 1;

[0024] The warehouse body 2 symmetrically arranged is fixedly connected on the main body 1;

[0025] The extension connecting part 3 is connected to the bin body 2.

[0026] The bin body 2 comprises a first empty bin 21 and a second empty bin 22, both of which are fixedly connected to the main body 1.

[0027] The two groups of bin bodies 2 and the main body 1 form a concave shape structure.

[0028] The concave shape structure extends inward, which slightly increases the size of the outline and turns the force on the balance weight to the frame when the loader is working.

[0029] The main body 1 comprises a first sealing plate 11, a second sealing plate 12, a third sealing plate 13 and a fourth sealing plate 14, the fourth sealing plate 14 is fixedly connected to the first empty bin 21 and the second empty bin 22, the first sealing plate 11 is fixedly connected to the top of the fourth sealing plate 14, the second sealing plate 12 is fixedly connected to the side wall of the fourth sealing plate 14, and the third sealing plate 13 is fixedly connected to the bottom of the fourth sealing plate 14.

[0030] Referring to Figure 2 , the extension connecting part 3 comprises a gasket 31, a bent plate 32 and a round pipe 34, the bent plate 32 is welded to the gasket 31, and the gasket 31 is fixedly connected to the bin body 2.
