Description

Dual-purpose door lock for goods elevator

This reality has novel a kind of Cargo Lift lock, especially the Cargo Lift Room door multifunctional door lock of relating to.

Loading is with needing to use door lock on the elevator, wherein external door is called Room door, and inside door is called gate.There is following deficiency in existing door lock: need handle, handle must see clearly that direction opens the door, and as mistaking one's bearings in a great rush, does not only open door, also easily causes handle by the spring pin fracture in shear; Existing latch hook pressure spring loses easily, loses closure effect; The contact of electrical equipment clutch does not meet the national newest standards requirement of industry; Because the existence of handle has influenced the distance of opening the door.

The purpose of this utility model is: a kind of Dual-purpose door lock for goods elevator is provided, make it be applicable to the Cargo Lift of various external-internal control, and easy for installation, with reliable, the electrical equipment clutch is synchronous with the integrated feasible electromechanics of switch of door, the contact of electrical equipment clutch meets the national up-to-date standard and the requirement of industry, makes things convenient for the control of elevator.

The purpose of this utility model is achieved in that Dual-purpose door lock for goods elevator, comprise adapter plate, latch hook, hammerlock, push rod, contact, the unblank frame and the flap of unblanking formed, an end that it is characterized in that hammerlock is installed on the active bearing pin, the other end cooperates with latch hook and contacts with contact, active bearing pin in the middle part of hammerlock and push rod, one end of push rod connects hammerlock, the other end connects the unblank frame and the flap of unblanking, the middle part of hammerlock also is provided with stage clip, and the elasticity direction of stage clip and the sense of motion of push rod are on a parallel lines.

The utility model is worked in the following manner: because hammerlock contacts with the contact that electrically contacts and opens absolutely, stage clip is contained on the hammerlock, when pushing inward by unblank frame and flap, drive push rod, force push rod to overcome stage clip power and drive hammerlock and make progress, reach disengaging appliance contact and mechanical synchronization and break off relations, door is opened, and has finished the task of unblanking.At closing time, hand also injects the frame of unblanking and moves to the limit to the direction of closing the door, after the door closure, hand is taken out and is left the frame of unblanking, because the latch hook stage clip works, utilizing stage clip to press down hammerlock coincide the contact of itself and contact switch, make latch hook drive push rod, add that latch hook push rod and unlocking apparatus (deadweight, stage clip) impel the latch hook closure, reach the mechanical electric apparatus synchronizing close, finish the latch hook closing course, the overall process that complete Room door is closed.The closure of unblanking is finished by same parts, and electrical equipment could start after contact switch coincide.

Characteristics of the present utility model are: Dual-purpose door lock for goods elevator has the mechanical electric apparatus synchronizing close, and it is simple and convenient to unblank, and does not have misoperation, more is not to leave no choice but go to finish with handle unblank.Add compression spring and be assemblied on the hammerlock, the deadweight free-falling body of unlocking apparatus and latch hook impels the hammerlock auto-closing, appliance contact is installed on the doorframe, contact is installed in door-plate, reaches door and is not related to electrical equipment and can't connects, and has guaranteed safety, advantage such as reliable, practical, convenient.The contact of electrical equipment clutch meets the national up-to-date standard and the requirement of industry, makes things convenient for the control of elevator.

The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment:

Fig. 1 is the utility model structural representation

As shown in the figure, Dual-purpose door lock for goods elevator, comprise adapter plate 1, latch hook 2, hammerlock 3, push rod 4, contact 5, the unblank frame 6 and the flap 7 of unblanking formed, one end of hammerlock 3 is installed on the active bearing pin 8, the other end cooperates with latch hook and contacts with contact, and promptly electrical equipment contact closure is locked and made to hammerlock and latch hook when locking.The middle part of hammerlock is provided with active bearing pin 9 and push rod, and an end of push rod connects hammerlock, and the other end connects the unblank frame and the flap of unblanking, and the middle part of hammerlock also is provided with stage clip 10, and stage clip and hammerlock are fixed, and the sense of motion of its elasticity direction and push rod is on a parallel lines.

Unblank frame 6 and unblank flap 7 and push rod 4 mechanical interlocks are the existing structures of unblanking, and when promoting to unblank frame 6, the flap interlock push rod of unblanking is freed hammerlock and latch hook.
