Description

Technical Field

[0001] The utility model relates to the technical field of tensile machine protection, in particular to a disassembly and assembly mechanism of a safety shield of a plastic tensile testing machine. Background Art

[0002] After the production of many plastics is completed, tensile tests are required. During the test using a tensile testing machine, the plastic may be broken and may injure the workers. At this time, safety shields come into being to play a protective role. However, the current safety shields do not have a quick-release connection mechanism, which means that the disassembly and assembly of the safety shields requires more time and energy of the workers, greatly increasing the workload of the workers.

[0003] For example, publication number CN202939090U describes a safety shield for an engineering plastic retainer tensile testing machine. This device belongs to the field of safety protection devices and consists of a fixed shield and a movable shield. The workpiece to be tested is fixed to the tensile fixture. The fixed and movable shields are constructed as uncovered rectangular boxes with facing openings, their inner cavities completely covering the fixed workpiece to be tested. The fixed shield is fixed to the upper tensile fixture, while the movable shield is connected to the upper tensile fixture via a fixture nut. This technical solution uses a working nut for installation, which also presents the aforementioned technical issues. Utility Model Content
