Abstract

The utility model relates to a door lock mechanism of a dumb waiter, which is an improvement of the structure of the door lock structure of a dumb waiter. The utility model is arranged on a landing car door and a slideway of the dumb waiter, the automatic opening and the automatic closing of the landing car door of the dumb waiter are realized, and the problem that landing car doors of past dumb waiters don not have the functions of the automatic opening and the automatic closing is solved. The utility model is composed of a wheel foot, a fixed wheel, a rocking wheel, a rotating shaft, a rotating arm, a bearing, a bearing sleeve, springs, spring set screws, a connecting bar, a door lock foot, a shaft, a shaft sleeve, a lock core and a locking fastener. The utility model has the advantages that the door lock mechanism of a dumb waiter realizes the automatic opening and the automatic closing of the landing car door of the dumb waiter by matching with a door knife, the rotation of the utility model is stable and flexible, the durability of the landing car door of the dumb waiter is improved, and the utility model can be used a the dumb waiter.

Description

The dumb waiter door lock mechanism

Technical field: the invention is the improvement to dumb waiter door lock mechanism structure, is installed on the layer door, realizes dumb waiter layer, gate automatic switch.

Background technology: the door lock of installing on the common in the past dumb waiter does not have auto-switch function, can't satisfy the demand of dumb waiter layer, gate automatic switch.

Summary of the invention: the purpose of the invention provides a kind of dumb waiter door lock mechanism that can realize dumb waiter layer, gate automatic switch, and the purpose of the invention is achieved through the following technical solutions: the dumb waiter door lock mechanism: be by wheel base, tight pulley, shake wheel, turning cylinder, swivel arm, bearing, bearing carrier ring, spring, spring jackscrew, pipe link, door lock base, axle, axle sleeve, lock core, pintle hook lock and constitute; On the wheel base, turning cylinder and tight pulley are installed, swivel arm is installed on turning cylinder, on swivel arm, install and shake wheel, bearing and bearing carrier ring are installed on the turning cylinder at the back side of wheel base, swivel arm with hit mounting spring and spring jackscrew between the wheel base, axle of installation on the door lock base, suit axle sleeve on axle, and the installation lock core, the pipe link two ends are installed in respectively on swivel arm and the lock core, and pintle hook lock is installed on the slideway of dumb waiter.

Pipe link is made two sections, connects with bolt, nut, and bolt hole is made strip hole.

Description of operation: the dumb waiter door lock mechanism is installed on layer door and the slideway, be that pintle hook lock is installed on the slideway, on in the door cutter mechanism, when the Xiamen cutter is stuck in tight pulley and shakes wheel, make and shake wheel and move obliquely upward, thereby drive the swivel arm moving axis that rotates and rotate, by pipe link the lock core pulling is moved right, contact switch disconnects, layer door is in the drive lower floor that is installed in the door cutter mechanism on the gate, gate is opened simultaneously automatically, when door cutter and the tight pulley of door cutter mechanism with after shaking the wheel disengaging, swivel arm swivel arm under the effect of spring resets, and lock core contacts with pintle hook lock again, the contact switch contact, layer door closed.

The advantage of the invention: be used with the door cutter mechanism and can realize dumb waiter layer, gate automatic switch; Changed the mode that traditional door cutter by on the cab is unblanked; On the turning cylinder of this door lock mechanism bearing has been installed, the swivel arm stability of rotation, flexibly, tight pulley is made with the rubber-like non-metallic material with shaking to take turns, and plays good sound deadening; Pipe link is made two sections and is made strip hole on it, leaves the process adjustments amount, has made things convenient for installation.

Description of drawings:

Fig. 1 is a dumb waiter door lock mechanism structural representation;

Fig. 2 is the birds-eye view of Fig. 1.

The specific embodiment: dumb waiter door lock mechanism: by wheel base 16, tight pulley 14, shake wheel 15, turning cylinder 19, swivel arm 18, bearing 10, bearing carrier ring 9, spring 13, spring jackscrew 12, pipe link 1, bolt 20, nut 2, door lock base 3, lock core 4, axle 7,8, axle sleeve 6, pintle hook lock 5 and constitute; On the wheel base, turning cylinder and tight pulley are installed, swivel arm is installed on turning cylinder, on swivel arm, install and shake wheel, shaking wheel drives the swivel arm moving axis that rotates and rotates, on the turning cylinder at the back side of taking turns base, bearing is installed, bearing carrier ring and bearing cap shim 11, bearing guarantees the turning cylinder stability of rotation, flexibly, swivel arm and hit the wheel base between mounting spring and spring jackscrew, spring resets swivel arm, lock core is contacted with contact switch 17 on the pintle hook lock layer door closed, and an axle is installed on the door lock base, suit axle sleeve on axle, make lock core and door lock base keep certain interval, reduce friction, lock core is moved flexibly, lock core is installed on the axle, pintle hook lock is installed on the slideway, and contact switch 17 is installed on lock core and pintle hook lock, and pipe link is made two sections, the middle bolt of using, nut is tightly locked, the bolt hole that pipe link cooperates with bolt is made strip hole, leaves the process adjustments surplus, the two ends of pipe link be fixedly mounted on respectively on swivel arm and the door lock base the axle on.When the upper and lower door cutter holder of door cutter mechanism is lived tight pulley and is shaken wheel, shake wheel and drive the swivel arm moving axis that rotates and rotate, swivel arm drives pipe link and moves, and pipe link pulling lock core moves right, and lock core is thrown off with pintle hook lock, and this moment, a layer gate opened; When upper and lower door cutter broke away from tight pulley and shakes wheel in the door cutter mechanism, swivel arm resetted under action of the spring, and lock core contacts with pintle hook lock, the contact switch contact, and layer door closed.
