Title: INDUSTRIAL PLUG FOR MARINE REFRIGERATION CONTAINER
Abstract:
Disclosed is an industrial plug for a marine refrigeration container, comprising a plug base (10). The plug base (10) is provided with a plug core fixing plate (40), wherein a plug pressing plate (20) adapted to wire connecting plug core assemblies (41, 42) is sheathed on an upper end of the plug core fixing plate (40), and a ring-shaped clamping block (22) protrudes from a lower end of the plug pressing plate (20). A first clamping ring (11) and a second clamping ring (12) are provided on an upper end of the plug base (10), and a ring-shaped groove (13) is formed therebetween, wherein the ring-shaped groove (13) is internally provided with two tension springs (14, 15) which are respectively fixed to the plug pressing plate (20) from two sides. A first snap groove (121) and a second snap groove (122) are provided at intervals on the inner side of the second clamping ring (12), and a slideway (123) is provided between the first snap groove (121) and the second snap groove (122). A rotation brake pin (50) is jacked upwards and rotated, the plug pressing plate (20) rotates along with the rotation brake pin (50) under the action of the tension springs (14, 15), and a rotation clamping block (54) is able to switch within the first snap groove (121) and the second snap groove (122). It is only when the rotation clamping block (54) is snapped into the first snap groove (121) or the second snap groove (122) that the rotation clamping block (54) is stabilized; and if stopping on the slideway (123), the rotation clamping block is immediately pulled back to the original position under the acting forces of the tension springs (14, 15).
