Abstract

A novel bucket tooth connection structure, its structure by: fixed column (1) on the ladder, lower fixed column (2), toothholder (3), bucket tooth (4), spring shim (5) constitute, bucket tooth (4) cover on toothholder (3) to through fixed column (1) and lower fixed column (2) locking on the ladder, toothholder (3) and bucket tooth (4) are connected successfully promptly, spring shim (5) are installed on the ladder between fixed column (1) and lower fixed column (2), its purpose is to the above-mentioned problem that current bucket tooth connection structure exists, provide one kind and aim at preventing down and assemble simple bucket tooth connection structure, promptly a novel bucket tooth connection structure.

Description

Novel bucket tooth connecting structure

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the technical field of fan blade manufacturing and designing, concretely relates to novel bucket tooth connection structure.

[ background of the invention ]

The bucket is a square bucket-shaped excavating tool with teeth and arranged at the front end of a bucket rod of the excavator, the bucket teeth are important parts on the bucket, are similar to teeth of people and are also wearing parts, generally, the bucket is formed by combining a tooth holder and the bucket teeth, the tooth holder and the bucket teeth are connected through tooth pins, and the wearing failure part of the bucket teeth is the tip of the bucket teeth, so that the bucket teeth can be independently dismounted and replaced. The existing matching structure of the tooth holder and the bucket teeth, the tooth holder and the tooth sleeve of the bucket of the hydraulic excavator are mostly connected by adopting a tooth pin at present, and the main purpose is to fix the tooth sleeve and the tooth holder. The connection form of current tooth round pin and bucket tooth is connected through interference fit usually, and is more difficult during the assembly of this kind of connection mode, and changes and join in marriage the structure insecure, and simultaneously, current structure falls on one side easily when using, influences the stability of using.

Therefore, the research on a novel bucket tooth connecting structure is of great practical significance.

[ Utility model ] content

To the above-mentioned problem that current bucket tooth connection structure exists, its aim at provides one kind and is fairly simple when aiming at the assembly, and assembly structure is firm, can not toward the bucket tooth connection structure who falls on one side during the use, promptly a novel bucket tooth connection structure.

In order to achieve the above object, the utility model relates to a novel bucket tooth connection structure, its structure by: fixed column (1) on the ladder, lower fixing column (2), toothholder (3), bucket tooth (4), spring shim (5) constitute, bucket tooth (4) cover on toothholder (3) to through fixed column (1) and lower fixed column (2) locking on the ladder, toothholder (3) and bucket tooth (4) are connected successfully promptly, spring shim (5) are installed on the ladder between fixed column (1) and lower fixed column (2).

In order to achieve the purpose, the novel bucket tooth connecting structure is characterized in that the lower end of the lower fixing column (2) is designed to be of a circular arc-shaped structure, namely, the lower end of the lower fixing column (2-1) is in a processing shape.

The utility model has the advantages as follows:

compared with the prior art, the assembly method has the advantages that the assembly method is simple and stable as the upper ladder fixing column is directly hit and inserted into the lower ladder fixing column; because the spring gasket is arranged, the spring gasket is anti-abrasion glue, and therefore the connection between the upper fixing column and the lower fixing column of the ladder is not easy to fall off.

The reference numbers marked in fig. 1 to 5 are respectively indicated as an upper fixing column (1), a lower fixing column (2), a tooth holder (3), a bucket tooth (4), a spring gasket (5) and a lower fixing column lower end (2-1).

[ detailed description ] embodiments

The novel bucket tooth connecting structure of the present invention is further described with reference to fig. 1 to 5.

In the preferred embodiment of the novel bucket tooth connecting structure of the present invention, the structure thereof is formed by: the upper ladder fixing column 1, the lower fixing column 2, the toothholder 3, the bucket tooth 4 and the spring gasket 5 constitute, the bucket tooth 4 cover on the toothholder 3 to through the locking of the upper ladder fixing column 1 and the lower fixing column 2, the toothholder 3 is connected with the bucket tooth 4 successfully promptly, the spring gasket 5 is installed on the ladder between the upper ladder fixing column 1 and the lower fixing column 2.

In the preferred embodiment of the novel bucket tooth connecting structure of the present invention, the lower end of the lower fixing column 2 is designed to be a circular arc-shaped structure, i.e. the processing shape of the lower fixing column lower end 2-1.

Appropriate changes and modifications to the embodiments described above will become apparent to those skilled in the art from the disclosure and teachings of the foregoing description. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention. Furthermore, although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.

Claims
