Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of breaker hammers, in particular to a novel through bolt assembly. Background Art
[0002] A breaker hammer can more effectively clear floating stones and soil in rock crevices when excavating the foundation of a building. Its main function is to break hard objects into smaller particles or fragments through high-speed impact force. Therefore, it is widely used in mining, metallurgy, railways, construction and other fields.
[0003] However, the current way of fixing the main body with the through-bolt assembly is that during the high-intensity operation of the breaker hammer, the piston and the steel chisel continuously collide, resulting in a gap between the through-bolt and the gasket. At the same time, during the collision, the gasket is easily displaced, causing the upper nut to loosen. For this reason, we propose a new through-bolt assembly. Utility Model Content
