[0022] To make the purpose, technical scheme and advantages of the present application more clear, specific embodiments will be described below in conjunction with the accompanying drawings. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] It is understood that the description is only exemplary and is not intended to limit the scope of the present application.

[0024] Some embodiments of the present application provide a metal plate for gearbox.

[0025] Embodiment one:

[0026] In combination with Figure 1-3 The present application provides a metal plate for gearbox, which comprises a plate mechanism 100 and a reinforcing mechanism 200. The plate mechanism 100 comprises a base plate 110, two reinforcing plates 120 mounted on the top and bottom of the base plate 110, and a corrosion-resistant plate 130 mounted on the outer side of the reinforcing plate 120. Three positioning holes 140 are formed on the base plate 110, the reinforcing plate 120 and the corrosion-resistant plate 130.

[0027] The reinforcing mechanism 200 comprises a hollow column 210 connected between the two corrosion-resistant plates 130 and a plurality of bolts 220 penetrating through the hollow column 210. The outer ends of the plurality of bolts 220 extend into the interior of the base plate 110, the reinforcing plate 120 and the corrosion-resistant plate 130, respectively.

[0028] Further, the base plate 110 is triangular, and the two outer edges of the triangle are arc-shaped, and the other outer edge is tooth-shaped. The plurality of corners of the triangle are arc-shaped. The reinforcing plate 120 and the corrosion-resistant plate 130 have the same shape as the base plate 110. The shape design of the base plate 110, the reinforcing plate 120 and the corrosion-resistant plate 130 makes it easy to manufacture and perfectly overlap, improving the appearance and structural stability of the product.

[0029] Further, the plurality of positioning holes 140 on the corrosion-resistant plate 130 and the plurality of positioning holes 140 on the reinforcing plate 120 coincide with the plurality of positioning holes 140 on the base plate 110. The base plate 110 and the reinforcing plate 120 are respectively sleeved on the outer side of the plurality of hollow columns 210. The hollow column 210 enhances the connection firmness of the corrosion-resistant plate 130, the reinforcing plate 120 and the base plate 110.

[0030] Furthermore, the substrate 110 is made of carbide steel, the reinforcement plate 120 is made of high-speed steel, and the anti-corrosion plate 130 is made of galvanized alloy steel. The thickness of the substrate 110 is greater than the thickness of the anti-corrosion plate 130, and the thickness of the anti-corrosion plate 130 is greater than the thickness of the reinforcement plate 120. Carbide steel has super hardness and can adapt well to the base position. High-speed steel is an alloy steel with high hardness, high wear resistance and high heat resistance. These advantages improve the adaptability of the reinforcement plate 120 in the applicable field. Then, galvanized alloy steel effectively prevents steel from corrosion and rusting, thereby extending the service life of steel.

[0031] Example 2:

[0032] Combine Figure 1 and Figure 3 As shown, based on the first embodiment, the multiple pins 220 in the base plate 110, the reinforcement plate 120 and the anti-corrosion plate 130 are evenly spaced and arranged in a ring shape, and the outer ends of the pins 220 are set to be conical. This layout design can improve the connection firmness between the base plate 110, the reinforcement plate 120, the anti-corrosion plate 130 and the hollow column 210.

[0033] Example 3:

[0034] Combine Figure 1 and Figure 3 As shown, in the above embodiment, the top and bottom ends of the hollow column 210 are integrally formed with an annular plate 300, and the two annular plates 300 are respectively embedded in the outside of the two anti-corrosion plates 130. The provision of the annular plates 300 can play the role of pressing the base plate 110, the reinforcement plate 120, and the anti-corrosion plate 130, further improving the connection firmness of the three.

[0035] The working principle and usage process of the present invention: When the device is put into actual use, after the base plate 110, the reinforcement plate 120, and the anti-corrosion plate 130 are pressed together, the hollow column 210 is inserted between the three. Since the hollow column 210 is installed according to the positioning hole 140, the multiple hollow columns 210 are combined with the outer ends of the base plate 110, the reinforcement plate 120, and the anti-corrosion plate 130 to make the connection between the three more secure, and then cooperate with the pin 220, which further improves the connection stability of the three.

[0036] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
