Drying kiln detecting door safety lock

Abstract

The invention provides a drying kiln detecting door safety lock. The drying kiln detecting door safety lock comprises an outer handle (4), an inner handle (5), a lock point (6), a transmission shaft (7), a shaft sleeve (8), M8 self-locking nuts (9), a countersunk bolt (12), a phi 50 outer flange (14), a phi 50 inner flange (16) and bolts (17); the transmission shaft (7) penetrates through an innercircle of the shaft sleeve (8); the outer handle (4) and the inner handle (5) are fastened at the two ends of the transmission shaft (7) by the M8 self-locking nuts (9); and the lock point (6) is fastened on an inner wall (1-1) of a detecting door edge frame (1) through the bolts (17). The drying kiln detecting door safety lock achieves an opening / closing limiting function to prevent influence onthe door opening and closing detecting effect by wrong operation, can achieve an escape function of two-way opening inside and outside a kiln to prevent wrong locking of workers in the kiln, and is prepared by adopting two special materials of stainless steel and fluororubber to achieve zero fault, no maintenance and effective prolonging of the equipment service life.

Description

technical field [0001] The invention relates to the technical field of safety locks, in particular to a safety lock for a detection door of a drying kiln. Background technique [0002] There is a kind of drying kiln in the wood drying industry. At present, this type of drying kiln occupies a dominant position in the wood drying market at home and abroad due to the large amount of material loaded, high drying efficiency, and relatively low construction and operating costs. In the prior art, most of the detection doors on the drying kiln are door locks that can be opened in one direction outside the kiln, and do not have the function of two-way opening inside and outside the kiln. Every year, accidents of staff being locked inside the kiln by mistake occur from time to time. There are certain security risks. Therefore, from the perspective of production safety, the present invention can effectively reduce the probability of risk accidents, and has a very long-term marketing v...
