Abstract

The utility model relates to a middle window lock for pull hooks, which comprises a lock handle and a pull hook. The utility model is characterized in that the middle window lock for pull hooks also comprises a shaft sleeve which is provided with a saddle-shaped retractor, a retracting spring and a crosspiece. The shaft sleeve is fixed to vertical material of window sashes. The pull hook is extended into the shaft sleeve. One end of the pull hook is connected with the lock handle and the other end is an 'L'-shaped structure. The pull hook is matched with a buckling hook of the vertical material of the window sashes and is locked tightly. The saddle-shaped end of the shaft sleeve is also provided with the retracting spring. The lock handle is provided with the crosspiece which can be positioned on the saddle-shaped end of the shaft sleeve. The window sashes are pulled and locked tightly in a transverse direction through rotating the pull hook to make the inner sash of a window top tightly an outer sash. The inner and the outer sashes are closed tightly without looseness. Through the saddle-shaped structure of the shaft sleeve, during rotation, the crosspiece of the lock handle is gradually raised.

Fig. 2 is a structure front elevational schematic of the present utility model;

Fig. 3 schemes to analysing and observe (being in unlocking condition) for A-A of the present utility model;

Fig. 4 schemes to analysing and observe (being in locking state) for A-A of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1～Fig. 4, the utility model comprises lock handle 1, group hook 2, the axle sleeve 3 of being with the saddle constriction device, retraction spring 4, crosspiece 5, latch screw 8, screw 9, fluid sealant 10 etc.

Dial hook 2 and can be inserted in the axle sleeve 3, the one end links to each other with crosspiece 5 on the lock handle 1 by latch screw 8; The other end is " L " type structure, can be buckled on the clasp 7-1 of the perpendicular material 7 of sash, makes perpendicular material 6 lockings of perpendicular material 7 of sash and sash.Axle sleeve 3 its saddle one ends of band saddle constriction device cooperate and can progressively tighten up dialling hook 2 with the crosspiece 5 on the handle 1, play tension two fan sash.A recess 3-1 is established at top at axle sleeve 3 saddle types one end, when tightening up the usefulness of making firm handle 2 when dialling hook, makes it can not scarifying; Establish a recess 3-2 at the axle sleeve mouth, make the usefulness of collection retraction spring 4; Axle sleeve 3 saddle types one end is provided with two-screw hole 3-4, for two-screw 9 axle sleeve 3 is fixed on the perpendicular material 6 of sash.The other end of axle sleeve 3 has half round cut 3-3, and gib head is reduced to axle sleeve 3 ends when dialling hook 2 opening, and half round cut 3-3 plays firm gib head effect, does not influence the sash pulling after guaranteeing to unblank.Retraction spring 4 retracts to gib head the end of axle sleeve 3 when group hook 2 is opened, do not influence the sash pulling after guaranteeing to unblank; Retraction spring 4 adopts the turriform design, and minimum takes up room during with the assurance compression.Lock handle 1 is provided with strut rail 5, and is fixed on latch screw 8 and dials on the hook 2, and by rotating, strut rail 5 progressively promotes on saddle or descends, and plays a part to loosen and tightens up group hook 2.Lock handle 1 can arbitrarily be selected various ways such as round, blossom type, cross, yi word pattern according to the requirement of decorating and use for use.
