Description

The aluminum window door lock

The utility model relates to a kind of aluminum window door lock.

The aluminum window door lock is a lot, and is miscellaneous on the structure, have in addition the joint portion stable not enough, produce problems such as using inconvenience.

Task of the present utility model provides a kind of aluminum window door lock of simple in structure, easy to use, good stability.

The technical solution of the utility model is: the aluminum window door lock is made up of panel, lock pin and drain pan, porose on the relevant position of drain pan, panel, lock pin inserting surface plate hole, pass the drain pan hole, lock pin can move up and down along two holes, lock pin is with spring on a section between panel and the drain pan, there is pin at the nearly panel place of lock pin, the lock pin upper end is fluted, the closely connected jam plate of lateral surface at the bottom of the panel, jam plate by securing member closely connected at the bottom of panel lateral surface, jam plate, securing member and panel are slidingly matched, and can move along lateral surface at the bottom of the panel is parallel.

When pushing lock pin downwards, jam plate promptly can snap in the groove of lock pin, fixing lock pin position, and lock pin inserts in the hole of two aluminium alloys window frames, and Aluminium alloy window-door is fixed, and finishes the invention task.

Fig. 1 is embodiment of the present utility model.

Fig. 2 is the embodiment of jam plate.

Be described in detail the utility model below in conjunction with accompanying drawing.

The aluminum window door lock, form by panel (1), lock pin (3) and drain pan (2), porose on the relevant position of drain pan (2), panel (1), lock pin (3) inserts panel (1), pass drain pan (2) hole, lock pin (3) can move up and down along two holes, there is pin (10) at the nearly panel place of lock pin (3), lock pin (3) upper end fluted (12), the closely connected jam plate of panel (1) end lateral surface (5), jam plate (5) is closely connected at panel (1) end lateral surface by securing member (7), jam plate (1), and securing member (7) is slidingly matched with panel (1).Can do parallel moving along panel (1) end lateral surface.(Fig. 1)

Female hollow cylinder (13) is arranged in the drain pan (2), recessed frame is arranged at panel (1) top, fastening bolt (6) inserts from the hole of the recessed frame of panel (1), is fastened on the interior female hollow cylinder (13) of drain pan (2), with panel (1), drain pan (2) fastening (Fig. 1, Fig. 2).

Securing member (7) is that a set screws component and nut (9) combine, and the set screws component is that screw head covers and is cast with unit of plastic.

Between fastening bolt (6) and securing member (7), spring (8) is arranged.Nearly head two sides of fastening bolt (6) have groove, and two sides of the rectangle hole slot (14) of jam plate (5) are positioned at fastening bolt (6) groove.The groove of the nearly head of fastening bolt (6), the gathering sill as jam plate (5) when mobile, the head of lock pin (3) can design latch cover (11).

When pressing down, jam plate (5) inserts lock pin (3) groove (12) and makes lock pin (3) location under the effect of spring (8), thereby lock pin (3) is fixed between the two aluminum window doorframes with lock pin (3), makes the window locking.
