Fan housing pressure relief lock
The invention provides a fan cover pressure relief lock which comprises a base, a lock body, a locking matching piece, an elastic element, an unlocking button and a button reset piece. Under the action of the button reset piece, the unlocking button can rotate to abut against the locking matching piece, the two ends of the elastic element abut against the lock body and the locking matching piece respectively, at the moment, the relative positions of the lock body, the locking matching piece and the unlocking button are locked through the elastic force of the elastic element, and therefore the covering cap is locked. When the air pressure in the fan cover is too large, the air pressure generates outward force on the opening cover and the base on the opening cover, the locking end of the lock body still abuts against the cover body, therefore, the lock body rotates relative to the base to be unlocked, meanwhile, the opening cover is pushed open through the air pressure, and pressure relief can be automatically conducted; when maintenance is carried out, the unlocking button is manually pressed to enable the unlocking button to rotate to be separated from the locking matching piece, manual unlocking can be carried out, the unlocking button is pressed to enable the unlocking button to rotate without applying too large force, and a maintainer can easily unlock the pressure relief lock and open the covering cap for maintenance.
本发明提供一种风扇罩泄压锁，包括基座、锁体、锁止配合件、弹性元件、开锁按钮以及按钮复位件。在按钮复位件的作用下，开锁按钮能够转动至与锁止配合件相抵接，弹性元件两端分别与锁体和锁止配合件相抵接，此时弹性元件的弹性力就将锁体、锁止配合件和开锁按钮的相对位置进行锁止，从而锁住口盖；而在风扇罩内的气压过大时，气压对口盖及其上的基座产生向外的力，锁体的锁止端部仍与罩体相抵接，因此锁体相对于基座转动解锁，同时气压推开口盖，即可自动进行泄压；在进行检修时，手动按压开锁按钮使其转动至与锁止配合件脱离，就可以手动解锁，且按压开锁按钮使其转动不需要施加太大力，检修人员可以轻松地解锁该泄压锁、打开口盖进行检修。
