TONG KEY LOCKING STRUCTURE FOR IMPROVING SAFETY PERFORMANCE AND REDUCING LOCKING LOAD

摘要

The present invention relates to a tong key lock structure. The tong key locking structure according to the present invention can reduce a load which is generated in the tong key locking structure by using an electromagnet instead of a conventional mechanical operation for locking and unlocking the tong key locking structure, thereby preventing the tong key locking structure from being damaged and malfunctioning. Also, an indicator for checking the rotation state of the tong key locking structure is formed in the tong key locking structure according to the present invention, thereby enabling a user to easily check the locking and unlocking states of the tong key locking structure with the naked eye.;COPYRIGHT KIPO 2018
