Description

Technical Field

[0001] The utility model relates to a connection structure, in particular to a connection structure of multiple counterweight blocks, belonging to the technical field of connection of multiple counterweight blocks. Background Art

[0002] A counterweight is a heavy object used to increase its own weight to maintain balance. Counterweights are usually made of various metal materials, such as cast iron, steel, stainless steel, etc. The shape and size of the counterweight can be designed and manufactured according to specific application requirements. In some cases, the counterweight can increase the weight of the object to meet specific requirements, such as increasing inertia, improving stability, etc. Counterweights can also be used to reduce the vibration of mechanical equipment or structures, and improve the smoothness and reliability of operation. In some mechanical equipment, vehicles and structures, in order to ensure the overall balance and stability, counterweights need to be added to offset the weight of other parts.

[0003] When using a counterweight, it is necessary to select and install the counterweight according to the specific situation. When selecting the required counterweight, a counterweight of suitable weight is generally selected for fixed use. Therefore, the use of the counterweight is not flexible. When some machines need to use counterweights of different weights during use, it is necessary to frequently replace the counterweights of different weights and fix the counterweight. In this process, the use of the counterweight is cumbersome, time-consuming and labor-intensive, which greatly reduces the efficiency of the use of the counterweight.
