In addition, because the screen window lock in the prior art screws in through the back of the window body, the whole appearance of the window body is not attractive.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that it is succinct to provide the outward appearance to prior art not enough, simple to operate to it is fixed with the window form to have a plurality of fixed points, improves factor of safety's screen window lock.

The utility model discloses the technical problem that solve is realized through following technical scheme:

a screen lock comprising: the lock comprises a lock body, a lock body fixing part and a handle; the top end of the lock body fixing part is provided with a clamping groove for clamping a window body, and the lock body is fixed on the lock body fixing part; the handle is connected with the lock body fixing part and is in a cover shape and can cover the lock body fixing part.

Preferably, the handle with the lock body fixed part is connected through first spacing portion, makes the handle with the degree of opening and shutting between the lock body fixed part is: 0 to 90 degrees.

Preferably, the first position limiting portion includes: the connecting shaft and be in a plurality of stoppers that set up on the connecting shaft.

Preferably, the lower end of the handle is provided with a second limiting part, the lower end of the lock body fixing part is provided with a second positioning clamping groove corresponding to the second limiting part, and when the handle is closed, the second limiting part is clamped in the second positioning clamping groove.

Preferably, the lower end of the lock body fixing part is provided with a fixing screw hole, so that the lock body fixing part is fixed with the window body through a screw.

The utility model discloses screen window lock, the outward appearance is succinct, simple to operate to it is fixed with the window form to have a plurality of fixed points, improves factor of safety.

The technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Detailed Description

Fig. 1 is a schematic structural view of the screen lock handle in the open/close state of the present invention, fig. 2 is a front view of the screen lock handle in the close state of the present invention, fig. 3 is a rear view of the screen lock handle in the close state of the present invention, and fig. 4 is a side view of the screen lock handle in the close state of the present invention. As shown in fig. 1 and with reference to fig. 2-4, the present invention provides a screen window lock, comprising: a lock body 1, a lock body fixing part 2 and a handle 3; the lock body fixing part 2 is provided with a clamping groove 21 for clamping a window body, the lock body 1 is fixed on the lock body fixing part 2, and the lock body 1 is fixedly connected with the lock body fixing part 2 through a screw or a bolt; the handle 3 is connected with the lock body fixing part 2, and the handle 1 is in a cover shape and can cover the lock body fixing part 2. In order to accord with people's operation custom, when operation handle 3, generally can not open more than 90 degrees just pulling, handle 3 with lock body fixed part 2 is connected through first spacing portion 4, makes handle 3 with the degree of opening and shutting between the lock body fixed part 2 is: 0 to 90 degrees. The first stopper portion 4 includes: the connecting shaft and be in a plurality of stoppers that set up on the connecting shaft. The position of every stopper corresponds with the angle that opens and shuts of handle 3, and the skilled person in the art can set up the quantity of stopper and with the stopper position that handle 3 angle that opens and shuts corresponds according to actual need, because of stopper restriction handle 3 angle that opens and shuts is prior art, therefore does not show in the drawing.

Referring to fig. 3 again, in order to prevent the handle 3 from shaking in the closed state, a second position-limiting portion 31 is disposed at the lower end of the handle 3, a second positioning slot (not shown) is disposed at the lower end of the lock body fixing portion and corresponding to the second position-limiting portion 31, and when the handle 3 is closed, the second position-limiting portion 31 is engaged with the second positioning slot.

Referring to fig. 1 and 3, in order to fix the screen window lock on the window better, a fixing screw hole 22 is formed at the lower end of the lock body fixing part 2, so that the lock body fixing part 2 is fixed to the window by a screw.

The working principle is as follows: the utility model discloses a screen window lock at first blocks the edge of the good mounting groove of window form offering in advance through draw-in groove 21, then will 2 blocks of lock body fixed part are in the mounting groove, and the screw is twisted to rethread fixed screw hole 22, make screen window lock and window form fixed connection. The utility model discloses a screen window lock is except passing through screw and window form fixed connection, still fixed through draw-in groove 21 and window form interlock, has increased fixed coefficient. Avoid because of the screw drops and leads to screen window lock and window form separation. Additionally, the utility model discloses a handle 3 covers lock body fixed part 2 for the design of lid form when the closure, not only makes the screen window lock whole pleasing to the eye, but also has reduced lock body 1 because of exposing in the external world, damage and the coefficient of wear that lead to.
