Abstract

The invention discloses a spinning locking device capable of locking a protective door and a lock body. The locking device structure consists of an opening handle, a spinning cone, a spinning thread bushing, a backstop end cover, a thread bushing end cover, an opening handle and lock body protecting cover and a locking rod. When the protective door needs locking, a protecting cover opening nut is pulled according to the preset thread rotating direction and the preset thread moving distance to expose a lock body opening hole, a key is inserted to turn a guiding spiral shaft, and the locking rod is inserted into a protective door locking base plate by twisting the opening handle so as to realize locking of the protective door.

Description

Technical field [0001] The invention relates to a protective door locking device, in particular to a spinning type protective door locking device which can protect even when the protective door of a thermometer is opened and locked. Background technique [0002] At present, there are two main types of protective door locking methods. One is the electronic code lock used for high-end entrance doors or unit doors. This type of protective door is used in less amount due to its special purpose, and the other is mid-range level and ordinary level. The used entrance door, the use of this type of protective door is relatively common, and the locking methods of this type of protective door are mainly one-way locking and multi-directional locking. These two locking methods are difficult to ensure the protective effect of the protective door during use. No failure, the protective door of the one-way locking method is too simple to lock, and it is easy to lose its protective effect, wh...
