Description
A kind of dual-use manual self-locking electricity antimony door lock belongs to the architectural hardware technical field.In the prior art, the freight elevator of manual inside and outside switch door, its manual door lock, electric interlock and mechanical self-latching are individual components, do not have reliable interlock protection effect each other.Its mechanical lock is the spring locking that resets, and reduces or loses as spring force, and then lock hook can not guarantee enough lengths of action, even lock in person even if; Lock hook with end the bolt strength deficiency, impact resistance is poor; Door lock can not reliably be locked.Be used for the electrical contact elements that electric interlock cuts off circuit, and do not have between the mechanical locking device directly and prevent the connection of misoperation, thereby make the locking state that electric interlock can not the reliable authentication mechanical lock.The electric interlock of outward opening door door lock of elevator only can guarantee the fastening position of layer door, can not guarantee lock hook engagement locking, and reliability is poorer.
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple in structure, reliable, easy for installation, is easy to adjust, check, can be used for to substitute the dual-use manual self-locking door lock of elevator of existing old-fashioned hand door lock.
Hammerlock 3 is connected on the base plate 1, push rod 13 links to each other with arm 3, unlocking handle axle 14 is separately fixed on the layer door with unlocking mechanism 16, driving lever 15 links to each other with unlocking handle axle 14, end bolt 12 and link, bump wheel 7 and be fixed on and bump on the wheel arm 8 with fixed head 6, locking bolt 5 with bump wheel arm 8 and be fixed on the same axle, be installed in the axle bed that is connected with fixed head, dust cap 9 is fixed on the fixed head 6.
Description of drawings:
Fig. 1 is the utility model structural front view;
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
Hammerlock 3 is connected on the base plate 1 by rotating shaft 2, push rod 13 links to each other with hammerlock by little 4, conducting strip 10 is fixed on the hammerlock head, unlocking handle axle 14 is separately fixed at appropriate location on layer door or the door leaf with unlocking mechanism 16, driving lever 15 links to each other with the unlocking handle axle, ending bolt 12 is connected with fixed head 6, electrical contact 11 is installed on the fixed head 6, movable locking bolt 5 with bump the wheel arm and be fixed on the same axle, bump the wheel 7 be fixed on bump the wheel arm on, be installed in the axle bed that is connected with fixed head 6, dust cap 9 is fixed on the fixed head.When layer door shifted to when closing the door the position, hammerlock and unlocking mechanism move with door leaf, when the lock hook head enters the position of engagement, lock hook promptly meshes with ending bolt under action of gravity, and when mesh volume reached certain-length, lock hook head conducting strip was just connected the electric interlock contact, the reliably locking of layer door, elevator can start, and lift car leaves onlocking zone, and movable locking bolt 5 is about to the hammerlock self-locking.When elevator enters onlocking zone, make and bump wheel and drive mechanical latch and unblank; At this moment outside unlocking handle can make push rod promote the hammerlock rotation and unblank.After hammerlock locking, can operate special-purpose lock and pin unlocking handle, door lock just can not be opened.
Compared with the prior art the utility model has the following advantages: 1, simple in structure, reliable, easy for installation; 2, be easy to adjust, maintenance and inspection can be used for substituting existing Manual door lock; 3, the locking functions that has dedicated lock when being used for the outward swinging door elevator, can be locked multi-layer door respectively,, opened the door by the unrelated person maloperation through stop to prevent the elevator operation, and when operating personnel leave, locking elevator door at any time.
