Description

The double-hook automatic locking

The utility model relates to a kind of slide door or window securing member, particularly a kind of lock for sliding door and window.

The most of lock bodies that will be installed on the jamb earlier of original lock for sliding door and window push lock, then the shifting block on the lock body are upwards carried, and lean on lock and lock body to fasten and close the doors and windows; Press the shifting block on the down lock body, lock separates with lock body, gets final product door and window, at this moment, opens and closes lock for sliding door and window and all needs manual operations, and is very inconvenient.

Existing a kind of lock for sliding door and window, for lock colludes, lock body has the latch hook of the button fit structure that interlocks, when being installed in lock body on the door and window side and pushing lock to, after button on the lock body and the hook on the lock are collided, latch hook interlocks and gets final product the self-closing doors window, but because employing is single face, single hook, single buckle structure, big or people is when shaking door and window at wind-force, automatically throw off easily, to antitheft, windproof, waterproof is unfavorable, again because the deadweight of slide door or window itself and under the acting in conjunction of people's thrust, easily the hook on the lock to be bumped disconnectedly, lack application life, when simultaneously lock for sliding door and window being installed, also higher to required precision, otherwise can lock phenomenon because of the excessive sky that occurs that interspaces in advance, so can not safety, bring into play the effect of door and window lock reliably.

The purpose of this utility model provides a kind of double-hook automatic locking of safe and reliable, long service life, and it can not only be effectively with the slide door or window fastening, and installs simple and convenient.

For achieving the above object, bearing support that the utility model double-hook automatic locking is connected as a single entity by lock, lock body, with lock body and rotating shaft and the torsionspring that is installed on the bearing support are formed, dead bolt on the lock is two-sided hook, and the outer clasp and the interior clasp that are interlocked with the two-sided hook of lock are arranged on the lock body.

There is inside hook on one side of clasp in addition, and another side has the clutch shaft bearing seat, and torsionspring and clutch shaft bearing seat are passed in rotating shaft, is fixed on the bearing support of lock body; Interior clasp simultaneously has second bearing support and spacing top board, and another side has shifting block, Yi Bian have and the corresponding and inside hook of outer clasp, second rotating shaft is passed on the bearing support that second bearing support is fixed on lock body; Dead bolt on the lock is sagittate two-sided hook.

The utility model double-hook automatic locking is owing to adopted double hook, two buckle structure, when therefore closing slide door or window, outer clasp on the lock body, interior clasp and dead bolt are the dual fastening of lock of two-sided hook, make that colliding and shake door and window is difficult for throwing off, and is not prone to empty the lock simultaneously; Owing to increased spacing top board on interior clasp, define the space between outer clasp and the interior clasp again, it is disconnected to make that slide door or window can be not that sagittate two-sided hook bumps to the lock upper lock tongue, long service life.

Below in conjunction with accompanying drawing the utility model double-hook automatic locking is described in further detail;

Fig. 1 is the utility model double-hook automatic locking structural representation;

Fig. 2 is the structural representation of the utility model double-hook automatic locking when opening outer clasp and interior clasp;

Fig. 3 is the sectional view of Figure 1A-A when SBR;

Fig. 4 is the sectional view of Figure 1A-A when locking state;

Fig. 5 is the sectional view of Figure 1A-A when opening.

Bearing support 2 that Fig. 1, Fig. 2, Fig. 3, Fig. 4 and double-hook automatic locking shown in Figure 5 are connected as a single entity by lock 12, lock body 1, with lock body 1 and rotating shaft 3 and the torsionspring 4 that is installed on the bearing support 2 are formed, dead bolt 13 on the lock 12 is two-sided hook, has on the lock body 1 with 12 pairs of locks to collude outer clasp 5 and the interior clasp 6 that is interlocked.

There is inside hook on one side of clasp 5 in addition, and another side has clutch shaft bearing seat 10, and torsionspring 4 and clutch shaft bearing seat 10 are passed in rotating shaft 3, is fixed on the bearing support 2 of lock body 1, at this moment forms a button, and this button has guaranteed that outer clasp 5 has inside active force; Interior clasp 6 one sides have second bearing support 9 and spacing top board 8, another side has shifting block 11, the hook corresponding and inside with outer clasp 5 arranged on one side, second rotating shaft 7 is passed on the bearing support 2 that second bearing support 9 is fixed on lock body 1, at this moment form another button, spacing top board 8 in this button defines the space between outer clasp 5 and the interior clasp 6; Dead bolt 13 on the lock 12 is sagittate two-sided hook.

When closing slide door or window under external force, the effect that is hooked in torsionspring 4 inside on the outer clasp 5 on the lock body 1 produces inside power down, between hook corresponding and inside on the interior clasp 6, limit space between outer clasp 5 and the interior clasp 6 by spacing top board 8, make the dead bolt 13 of the two-sided hook of arrow-shaped on the lock 12 pass the automatic dual fastening in space between outer clasp 5 and the interior clasp 6, slide door or window is promptly closed.

When opening slide door or window, stir the shifting block 11 that is cast as one with interior clasp 6, under the drive of shifting block 11, outwards open on the interior clasp 6, outer clasp 5 also outwards opens under the promotion of the spacing top board 8 on the interior clasp 6, sagittate dead bolt 13 is thrown off with outer clasp 5 and interior clasp 6, and mobile slide door or window can be opened.At this moment, torsionspring on the outer clasp 54 produces the inside power and the effect of interior clasp 6 upper limit top boards 8, makes space that generation between outer clasp 5 and the interior clasp 6 is certain and setting back.

When the double-hook automatic locking is in SBR, as shown in Figure 3, lock 12 with sagittate two-sided hook lock tongue 13 is installed on doorframe or the window frame, at this moment, corresponding each other between the inside hook on inside hook and the interior clasp 6 on the outer clasp 5 on the lock body 1, the torsionspring 4 that connects on the outer clasp 5 produces inside active force with under the qualification of the spacing top board 8 that interior clasp 6 is cast as one, produce certain space between outer clasp 5 and the interior clasp 6, making on the lock 12 can be not directly and the hook generation head-on crash on outer clasp 5 and the interior clasp 6 with sagittate two-sided hook lock tongue 13.

When the double-hook automatic locking is in locking state, as shown in Figure 4, on the lock 12 with sagittate two-sided hook lock tongue 13 pass between outer clasp 5 on the lock body 1 and the interior clasp 6 the space, make on the outer clasp 5 that corresponding and inside hook and the sagittate two-sided hook lock tongue 13 of being with on the lock 12 are distinguished fastenings on the inside hook and interior clasp 6.

When the double-hook automatic locking is in opening, as shown in Figure 5, shifting block 11 in stirring on the clasp 6, interior clasp 6 outwards opens, outer clasp 5 also outwards opens under the effect of the spacing top board 8 on the interior clasp 6, be with this moment sagittate two-sided hook lock tongue 13 to throw off on the lock 12, mobile slide door or window can be opened.
