Abstract

The utility model relates to a latching device for an inner casement window with two latching points. The utility model is sheathed and latched by a box body on a trapezoidal part in the middle of a moving rod and a fixing rod. The middle of the box body is provided with a convex semicircular cone cover, and a cone with 6 square gear teeth is arranged in the cover. The gear teeth are engaged with square holes on the moving rod. The cone rotates to drive the moving rod and latching posts to move, and the latching posts are positioned at both ends of the moving rod. When the latching posts move into the inner side of a latching block on a window frame, a window sash is latched.

Description

A kind of Latching device for window

The utility model relates to a kind of window lock and closes device, particularly has the casement window opening inwards transmission locking device of two lock point locking functions.

At present, known Latching device for window is to be that 7-10 millimeters circular metal rod curves L shaped with a diameter, its long part is a bolt rod, its short part is a handgrip, be fixed with 1-2 semicircle short hoops on the one rectangle metal sheet, under the stirring of handgrip, bolt rod can slide up and down in short hoop, when insertion was fixed on the short hoop of semicircle on the window frame, window was by locking.Because this Latching device for window has only a lock point, and is installed on the upper end or the lower end of window more, so when window was subjected to outside powerful pulling, sash locking device was loosening easily, damage, poor stability.

The purpose of this utility model is to make sash that two lock points be arranged on the vertical stile of window frame, and the handle of dependence rotational fixation on the sash frame, but just locking sash, make handle have two functions of switch sash and locking sash simultaneously, thereby improve the convenience of sash use and the safety of locking.

The purpose of this utility model is achieved in that deciding in the middle of bar and the moving bar one section and all is trapezoidal, and 6 slots are arranged on the moving bar, deciding the trapezoidal portions of bar and moving bar is sealed by a casing cover, deciding bar fixedlys connected with this casing, moving bar can move up and down in this casing, the one semicircle gear wheel cover that protrudes is arranged in the centre of this casing, the circular hole of its both sides for connecting, gear wheel with 6 rectangle teeth is arranged in it, in the middle of the gear wheel is a square internally and round externally shape hole, axle is played on the narrow limit that this Kong Youyi outwards routs up, and can rotate in the circular hole of gear wheel cover.Perforation engagement on teeth on the gear wheel and the moving bar, when rotating the handle handle, handle square plug in the insertion gear wheel square hole is with regard to the turn gear wheel, teeth on the gear wheel are just stirred moving bar and are moved up and down, the lock that drives moving bar two ends simultaneously moves up and down in deciding the rectangle hole slot of bar, when lock slid into the lock dog inboard of being fixed on the window frame, sash was just by locking.

Owing to adopt such scheme, just can make sash that the locking point of two sides is arranged, to improve the safety of window, simultaneously, when being used, closing window and move and can carry out continuously with locking with the handle of given shape, very convenient.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.

Fig. 1 is a vertical section of the present utility model constructional drawing.Fig. 2 is the outward appearance front view of Latching device for window.Fig. 3 is the scheme of installation of Latching device for window.1. locks 2. are decided square opening 7. in the middle of moving bar 4. casings 5. gear wheels 6. gear wheels of bar 3. and decide rectangle hole slot 9. on the rectangle hole slot 8. moving bars on the bar and decide the rectangle teeth that rectangle perforation 11. gear wheels on the bars are moved in nail hole 10. on the bar among the figure

In the accompanying drawings, screw passes the nail hole (7) of deciding on the bar (2) and the hole slot (8) on the moving bar (3), and Latching device for window is fixed on the vertical frame of sash.When the square opening (6) in the middle of the square plug insertion gear wheel (5) of handle rotates, the teeth (11) of gear wheel (5) are stirred the perforation (10) on the moving bar (3), bar (3) is moved up and down, and drive the lock (1) fix its two ends and in deciding the rectangle hole slot (7) of bar (2), move up and down, when lock (1) moved to the lock dog inboard of being fixed on the window frame, sash was just by locking.

Claims

1. a Latching device for window is formed by deciding the stack of bar and moving bar, it is characterized in that a gear wheel is arranged in the casing, at moving bar two ends a lock is arranged respectively.

2. locking device according to claim 1 is characterized in that deciding bar and moving bar mid portion is trapezoidal, and is sealed by the casing cover, decides bar and casing is connected, and moving bar can move up and down in casing.

3. locking device according to claim 1 is characterized in that the gear wheel center of circle in the casing is a square internally and round externally axle, can rotate in the circular hole of box bilateral wall, and gear wheel one side has square teeth, with the square perforation engagement of moving bar.
