Specific embodiment
A specific embodiment of the invention is made further detailed below against attached drawing by the description to optimum embodiment
Thin explanation.
The invention discloses a kind of non-return self-locking devices for ventilating skylight locking；Device disclosed by the invention is suitble to each
Class needs the workshop with opened skylight, while also realizing that skylight opens ventilation and closes the performance of heat preservation, and valve plate installation radix saposhnikoviae
To time self-locking device, it is ensured that the stabilization and windbreak function of bad weather, windy season and northern area skylight dormer valve plate；In reality
Ventilating skylight is a commonly used equipment in the production of border, and the structure of ventilating skylight is to belong to a known features, and which is not described herein again,
It simultaneously include valve board structure in ventilating skylight, the unlatching of valve board structure and closure can be realized in installation ventilating skylight workshop
Ventilation and heat preservation, while valve plate is also connected with a wirerope, which is connected with driving device, this driving device can be with
Motor is also possible to other structures, be mainly used for provide valve plate unlatching when pulling picture external force, here wirerope with hereafter
In wirerope belong to two wirerope, wirerope here can be called main rope；Traditional valve plate without other fixed structures,
The closure of valve plate is often realized using valve plate self gravity, when encountering biggish air-flow, valve plate can be jacked up, when falling after rise again,
It is relatively easy to cause biggish noise, while being possible to damage valve plate overall structure；So in order to solve such technical problem,
The invention discloses a kind of non-return self-locking devices；The non-return self-locking device includes Slip-preventing hook 1, and the Slip-preventing hook 1 connects
