Description

Short-term manual and automatic integrated double-insurance structure connector Technical Field The utility model relates to the technical field of engineering equipment, in particular to a short manual and automatic integrated double-insurance structure connector. Background In the structure of the excavator, the connector is a connecting device for connecting the vehicle body and the excavator bucket, the axle distance of the conventional welding type/casting type connector is too large, the total length is too long, the height of the conventional welding type/casting type connector influences the excavating force after the excavator bucket is installed, the length of the conventional connector influences the excavating wall corner, the overall dimensions of the connectors can be seen in fig. 1-4, fig. 1 is a P-series connector, the axle distance of the connector is 45mm, the axle distance is 230mm, the axle distance is 215mm, the total length is 581mm, fig. 2 is a casting type connector, the axle distance of the connector is 45mm, the axle distance is 230mm, the axle distance is 219mm, the total length is 613mm, fig. 3 is an H-type connector, the axle diameter of the connector is 44.5mm, the axle distance is 340mm, the axle distance is 223mm, the total length is 694mm, the conventional connectors are longer, fig. 1 is because of the nose-type protrusions at the left end of the lifting hook and the movable hook are influenced by the length, fig. 2 is because of the existence of the lifting hook, the rear end of the lifting hook is longer than the shell, the rear end of the lifting hook is also designed to be short, and the front end of the cylinder is not occupied due to the fact that the existing side is designed to the front end is short side of the front end of the air cylinder is designed to be short. These existing connectors also have the problems of too large wheelbase and too long total length, which not only affects the use effect (the digging force), but also causes the front edge corner to be touched when the front edge corner is dug by the overlong front end, and the residual soil is left. Therefore, in view of the shortcomings of the practical manufacturing and implementation of the above scheme, the connector is modified and improved, and the technical spirit and concept are adopted, and the short manual and automatic integrated double-insurance structure connector is specially provided by the assistance of professional knowledge and experience and after multiparty thinking and experiments, so that the problems of too large axle distance and too long total length of the existing connector are solved, and the negative influence caused by too long length is reduced. Disclosure of utility model The utility model aims to provide a short manual and automatic integrated double-insurance structure connector, which is used for solving the problems of overlarge wheelbase and overlong total length of the existing connector and reducing the negative influence caused by overlong length.
