Description

Technical Field

[0001] The utility model belongs to the technical field of engineering machinery, and in particular relates to a large tool box for an excavator. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] With the development of mechanization in engineering construction, excavators are increasingly used in engineering construction. During daily operations, excavators need constant maintenance, and simple repairs are also required during the construction process. Therefore, excavators are generally equipped with large tool boxes to store daily maintenance tools and maintenance parts.

[0004] However, there are still some problems that need to be solved in the current large toolboxes for excavators: (1) The existing large toolboxes for excavators are manufactured by processing and welding parts, and the welding process cannot guarantee the quality of the finished toolbox. The toolbox is easily deformed after welding, and the overall structure is easily damaged by bumps and vibrations during operation, and the appearance is not beautiful. (2) At present, a switch damper is set at the contact position between the toolbox cover and the box body, and a whole rubber strip is used for wrapping. The aging resistance effect is not good. In addition, if the rubber strip is damaged or bulged somewhere during use, the whole rubber strip needs to be replaced, and the maintenance cost is high.

[0005] A new type of excavator toolbox disclosed in a Chinese utility model patent (application number: 201621125204.9) is provided with a limit link on the right side cover support platform, one end of the limit link is pivotally connected to the corresponding side cover, and the other end is pivotally connected to the preset mounting hole of the right side cover support platform. It is understandable that when closing the box cover, due to the high height of the installation platform of the large toolbox for excavators on the excavator, the staff needs to lean into the toolbox to take the items inside the toolbox, and the above structure cannot realize that the toolbox cover keeps the position fixed by itself when it is opened. When the staff leans into the toolbox to take the items, the toolbox cover is easily affected by foreign objects to close and cause harm to the staff. Even if the limit link is fixed manually, the staff needs to lean into the toolbox to operate, which makes the use of the toolbox very inconvenient. Utility Model Content
