[0002] The cross plate is one of the important connectors in power fittings, mainly used to connect and support power equipment. In the power system, since the power needs to be transmitted and controlled between devices, they must maintain close contact and good stability. The cross plate is an important component used to achieve this purpose, but the existing cross plate has low flexibility and has not been effectively improved in terms of increasing length, so it is necessary to improve the structure. Utility Model Content

[0003] The purpose of the utility model is to provide a wear-resistant metal connector in order to solve the above technical problems.

[0004] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] Each chute is provided with two extension plates, and the extension plates are provided with a plurality of connection holes. The extension plates are slidably connected with the chute, and the lengths of the upper and lower sides of the cross-shaped connection plate are adjusted by setting the connection holes.

[0007] The diameter of the first mounting hole is 30 mm, and the diameters of the second mounting hole and the connecting hole are both 40 mm.

[0008] The axial center distance between adjacent connecting holes is 60 mm.

[0009] The thickness of the extension plate is 20 mm.

[0010] The cross-shaped connecting plate and the extension plate are made of carbon steel, and the surfaces of the cross-shaped connecting plate and the extension plate are sprayed with an anti-corrosion epoxy resin layer, and the surface of the anti-corrosion epoxy resin layer is sprayed with a wear-resistant layer. Carbon steel is a high-strength, high-toughness alloy steel with good corrosion resistance and wear resistance. By setting the sprayed anti-corrosion epoxy resin layer and the wear-resistant layer, the corrosion resistance and wear resistance of the carbon steel are increased, and the service life is extended.

[0011] The extension plate and the cross-shaped connecting plate are connected to the slide slot by bolts and nuts. When in use, when the length of the cross-shaped connecting plate is required, the two upper extension plates are simultaneously slid out of the slide slot to increase the length, and then fixed by bolts and nuts.

[0012] The beneficial effects of the utility model are as follows:

[0013] By setting an extension plate, the service length of the cross-type connecting plate can be adjusted to suit installation conditions of different lengths; by setting a spray-coated anti-corrosion epoxy resin layer and a wear-resistant layer, the corrosion resistance and wear resistance of the carbon steel can be increased and the service life can be extended.

[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figures 1 to 5As shown, this embodiment provides a wear-resistant metal connector, including a cross-shaped connecting plate 1, a first mounting hole 2 is opened on the left and right sides of the cross-shaped connecting plate 1, a slide groove 3 is symmetrically arranged on the front and rear sides of the cross-shaped connecting plate 1, and a second mounting hole 4 is arranged on the top and bottom of the slide groove 3, and the second mounting hole 4 connects the slide grooves 3 on the front and rear sides;

[0024] Two extension plates 5 are provided on each chute 3, and a plurality of connection holes 6 are provided on the extension plates 5. The extension plates 5 are slidably connected to the chute 3, and the lengths of the upper and lower sides of the cross-shaped connection plate 1 are adjusted by setting the connection holes 6. In the present utility model, the number of the connection holes 6 is designed to be 3.

[0025] The diameter of the first mounting hole 2 is 30 mm, and the diameters of the second mounting hole 4 and the connecting hole 6 are both 40 mm.

[0026] The axial center distance between adjacent connecting holes 6 is 60 mm.

[0027] The thickness of the extension plate 5 is 20mm. The overall thickness of the cross-shaped connecting plate 1 is 80mm, and the thickness of the extension plate 5 is one-fourth of the cross-shaped connecting plate 1, so the thickness of the two extension plates is exactly 40mm, which is half of the cross-shaped connecting plate. The depth of the chute is consistent with the thickness of the extension plate. After deducting the depth of the two chute, the thickness of the middle of the cross-shaped connecting plate is 40mm. The thickness design between the components ensures that when the extension plate extends out of the chute, the extension plate and the cross-shaped connecting plate can maintain sufficient strength.

[0028] The cross-shaped connecting plate 1 and the extension plate 5 are made of carbon steel, and the surfaces of the cross-shaped connecting plate 1 and the extension plate 5 are sprayed with an anti-corrosion epoxy resin layer 7, and the surface of the anti-corrosion epoxy resin layer 7 is sprayed with a wear-resistant layer 8. Carbon steel is a high-strength, high-toughness alloy steel with good corrosion resistance and wear resistance, and by providing the sprayed anti-corrosion epoxy resin layer 7 and the wear-resistant layer 8, the corrosion resistance and wear resistance of the carbon steel are increased, and the service life is extended.

[0029] The extension plate 5 and the cross-shaped connecting plate 1 are connected to the slide groove 3 by bolts 9 and nuts 10. When in use, when the length of the cross-shaped connecting plate 1 is required, the two upper extension plates 5 are simultaneously slid out of the slide groove 3 to increase the length, and then fixed by bolts 9 and nuts 10.
