Abstract

The utility model relates to a machinery lock switch which is an improvement on the lock switch of a dishwasher. A small fixing post is rivetedly connected with a lock handle, and a big fixing post is connected with a nylon gasket and a lock fixing seat; one end of a spring is hooked with the slotted hole of the lock fixing seat, and the other end of the spring is hooked with the groove of a stepped plate of the lock handle; the lock handle and a lock hook are sheathed on the big fixing post. The utility model has the advantages of simple and reasonable structure, can be arranged on the door of the dishwasher, and has the self-locking function and is used safely.

Description

The mechanical lock buckle switch

The utility model relates to a kind of improvement of anchor switch of dish washing machine door, is a kind of mechanical lock buckle switch specifically.

The switch of existing dish washing machine door all adopts the magnet type switch, pulls at slightly after door shuts, and will use Men Lakai very dangerous reliable.

The utility model purpose is to overcome the shortcoming in the above-mentioned technology, proposes a kind of mechanical lock buckle switch, needs only the position that switch knob is forwarded to the pass, just Men Lakai can not had auto-lock function.

The utility model purpose is realized by following technical scheme:

This mechanical lock buckle switch, it is characterized in that having the riveted joint of a little fixed leg and snap close handle, a big fixed leg is connected with nylon washer and snap close holder, snap close handle and snap close hook are sleeved on the big fixed leg, end by spring colludes on the slotted hole of snap close holder, and the other end of spring colludes the trapezoidal plate groove at the snap close handle.

The snap close holder is the mutually perpendicular surface plate of L type, a crescent-shaped slot and a circular hole that inserts big fixed leg are arranged on vertical panel, insert in the crescent-shaped slot with the little fixed leg of snap close handle riveted joint, and can in crescent-shaped slot, move, two installing holes and a slotted hole are arranged on the horizontal plane of snap close holder, and an end of spring colludes on the slotted hole of horizontal plane.Big fixed leg is loaded in the circular hole at snap close holder and vertical plane center, and the little fixed leg of snap close hook, snap close handle and snap close handle rotates around big fixed leg.Have 2 elongated slots in the snap close hook, be enclosed within respectively on big fixed leg and the little fixed leg.

Snap close handle and snap close hook can be around big fixed leg rotations, and little fixed leg also around big fixed leg rotation, moves in the crescent of snap close holder.The turned position of snap close handle is by little fixed leg limiting of shift position and being defined in crescent.Two elongated slots in the snap close hook are enclosed within respectively on big fixed leg and the little fixed leg.When the snap close handle rotates, drive little fixed leg and slide in the crescent of snap close holder, an elongated slot that also drives in the snap close hook also moves with little fixed leg, and another elongated slot is around big fixed leg rotation and upper and lower moving.The start-stop position of snap close hook also is subjected to the restriction of crescent on the snap close holder.When operable lock attacker handle turns clockwise, the crescent top of little fixed leg to the snap close holder, this moment the position for closing, the snap close handle is rotated counterclockwise, the crescent bottom of little fixed leg to the snap close holder, this moment the position for opening.Both ends of the spring is hung on the slotted hole of the trapezoidal plate groove of snap close handle and snap close holder, when the snap close handle rotates to right-hand member, spring is subjected to pulling force, make the snap close handle clockwise rotate power, because crescent limits moving of little fixed leg on the snap close holder, make the snap close handle be forced to stop motion, the snap close hook stops at this.As not operation again of handle, the snap close hook is in locking state forever, reaches auto-lock function, makes the mechanical lock buckle switch safe and reliable.

The utility model advantage is simple and reasonable for structure, easy to make, its door that is installed in dish-washing machine gone up replace original magnet type switch, because auto-lock function is arranged, and safe and reliable, need only the position that handle is placed the pass, door just can not drawn back.

Embodiment of accompanying drawings:

Fig. 1, Fig. 2 are a kind of 2 views of mechanical lock buckle construction of switch,

Fig. 3 is snap close handle rotary state figure,

Fig. 4 is snap close hook rotary state figure,

This mechanical lock buckle switch, little fixed leg (6) is riveted together with snap close handle (1), big fixed leg (5) connects as one with nylon washer (7) and snap close holder (2), spring (3) one ends collude on the slotted hole of snap close holder (2), and the other end colludes the trapezoidal plate groove at snap close handle (1).Snap close hook (4) and snap close taper knob are contained on the big fixed leg.When turning clockwise snap close handle (1), when little fixed leg (6) forwards the crescent top of snap close holder (2) to, the position of this mechanical lock buckle switch for closing, when rotating counterclockwise the snap close handle, when little fixed leg forwards the crescent bottom of snap close holder (2) to, the position that the mechanical lock buckle switch is out.
