Description

Technical Field

[0001] This utility model belongs to the field of compression technology, specifically, it relates to a four-corner fixed rod compression mechanism. Background Technology

[0002] Hydraulic compression equipment is an important type of mechanical device that can compress liquids or gases to high pressure, thereby obtaining high-energy-density energy. With the continuous advancement of industrial development, the application scope of hydraulic compression equipment is constantly expanding, and the demand for hydraulic compression equipment with excellent performance, reliability, safety, low cost, ease of use, and high efficiency is also constantly increasing.

[0003] Currently, in scissor lift hydraulic compression equipment, such as Figure 1 As shown, one end of the top of the scissor telescopic mechanism a is connected to the fixed plate b, and the other end is slidably mounted on the fixed plate b. One end of the bottom of the scissor telescopic mechanism a is hinged to the lower pressure plate c, and the other end is slidably mounted on the lower pressure plate c. With this configuration, during the compression process, as the scissor telescopic mechanism a extends, the point of force application on the lower pressure plate c at the sliding connection end of the scissor telescopic mechanism a will move inward. This causes the lower pressure plate c to be subjected to unbalanced forces during the compression process, affecting the stability and service life of the equipment. At the same time, the object being compressed will not achieve the desired compression effect due to uneven force. Utility Model Content
