Problems solved by technology

[0003] With the continuous development of science and technology, lead doors are used more and more widely. Now lead doors are suitable for scientific research, testing, medical treatment, production and other construction units with radiation sources, which can effectively protect against X, gamma rays and neutron rays. It is an essential device for radiation protection in industrial flaw detection exposure room. When the installation site is too small, the traditional push-pull protective jaws and flat swing protective jaws have problems such as inconvenient installation, so it is not conducive to user installation, and the traditional jaws lack automatic protection. device, people often collide accidentally when pushing and pulling, which causes damage to the equipment and reduces the service life of the equipment

Abstract

The invention provides a rotary lead door with an automatic protection function. The rotary lead door comprises a main body, wherein a lead door body is fixedly mounted on the outer side of the main body; a first lead plate and a second lead plate are mounted in the lead door body; a movable part is fixedly mounted on the inner wall of the main body; a mounting part is mounted in the movable part; a groove is formed in the mounting part; and a mounting spring is fixedly mounted on the inner wall of the groove. According to the rotary lead door with the automatic protection function, when the lead door is quickly pushed, the movable part is promoted to generate a relatively large centrifugal force due to overexertion of people behind, and then a fixed clamping piece pulls the mounting spring to move outwards, so that the fixed clamping piece is attached to a fixed clamping groove in a fixed shaft; and the fixed clamping piece is effectively clamped by utilizing the fixed clamping groove, so that the rotating force of the lead door body is effectively relieved, automatic protection of people in front is realized, and the injury caused by the fact that people do not notice the lead door to get close is avoided.

Description
