Specific embodiment

The technical solution of the utility model is illustrated with embodiment with reference to the accompanying drawing.

As shown in Figure 1 to Figure 3, a kind of window gear lock described in the utility model, including ontology 1 further include set on described The positive handle 2 of ontology 1,1 front of ontology have leader hole 11 for accommodating the handle 2, the grip hole 11 1 End has a through-hole 12, and 12 back side of through-hole is equipped with a gear 3, and described 2 one end of handle passes through the through-hole 12, the handle Rotatably hinged along the plane where the axis of the gear 3 between 2 and the gear 3, i.e., handle 2 can be swung up and down, in this way It can be taken out from grip hole 11, but when handle 2 is rotated around its fixing end, it further includes one being set to that gear 3, which also can be rotated and then, The latch fitting 4 at 1 back side of ontology, the latch fitting 4 are slidably connected to the ontology 1, the latch fitting along the length direction of the ontology 1 4 have a spur rack 41 engaged with the gear 3, and specifically the spur rack 31 of latch fitting 4 is located at its one side, such gear 3 When rotation, latch fitting 4 can be moved up and down, and the fixing end of the handle 2 is equipped with a spring and the handle 2 is made to be in pop-up shape State, 11 other end of grip hole are equipped with a fastener 5,5 end of fastener and the handle 2 along 1 direction of ontology sliding End cooperates for blocking the handle 2, when the handle 2 is pressed into the grip hole 11, is equipped with spring in the fastener 5 It pops up it toward the direction of handle 2, and blocks the handle 2 and up popped up for limiting the handle 2, such handle 2 can It is overall beautiful to conceal in grip hole 11.

Specifically, the fastener 5 is additionally provided with key lock 51 for limiting the sliding of the fastener 5, when handle 2 is concealed When in grip hole 11, key lock 51 to latching, so that it may not allow handle 2 to pop up, can thus lock window, avoid leading to Handle 2 is crossed to open.

Specifically, 5 front of fastener, which is additionally provided with anti-skid chequer, conveniently pulls the fastener 5, because opening handle 2 is to want Fastener 5 is slid down, increasing anti-skid chequer can be more convenient to slide.

Specifically, the latch fitting 4 has long limit hole 42,1 back side of ontology has limited post 13, the limited post 13 slide in the limit hole 42, and the outer diameter of limited post 13 is matched with the aperture of limit hole 42, can thus limit latch fitting 4 Shift position, it is ensured that engaging between the gear 3 and spur rack 41 so that transmission it is relatively reliable.

The embodiments of the present invention are described in conjunction with attached drawing above, but the utility model be not limited to it is above-mentioned Specific embodiment, the above mentioned embodiment is only schematical, rather than restrictive, the common skill of this field Art personnel are not departing from the utility model aims and scope of the claimed protection situation under the enlightenment of the utility model Under, many forms can be also made, these are belonged within the protection scope of the utility model.
