Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention; the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; furthermore, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, as they may be fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1 to 5, the opening-adjustable sliding window limiting lock comprises a lock body 1, a movable bolt 2, a shift lever 4 and a pin shaft 5, wherein the movable bolt 2 is vertically movably installed in the lock body 1, one end of the shift lever 4 is rotatably hinged to the movable bolt 2, the other end of the shift lever extends out of an opening 10 in one side of the lock body 1, the shift lever 4 is close to the hinged end and is further provided with the pin shaft 5, the shift lever 4 is rotatably connected to the lock body 1 through the pin shaft 5, the lock body 1 is provided with a through groove 6 for the pin shaft 5 to horizontally move, an elastic pressing strip 7 is further arranged above the pin shaft 5 in the lock body 1, and the other end of the elastic pressing strip 7.

The lock body 1 is arranged at the top end of the side surface of the window 3, and a plurality of lock holes 9 which are distributed at equal intervals are arranged on the window frame 8.

The top end of the movable bolt 2 is an inclined plane which faces the side of the window 3 and is closed, and the bolt can penetrate through the lock body 1.

The elastic pressing strip 7 is an inverted 'concave' thin sheet, and the bottom of the elastic pressing strip 7 is abutted to the pin shafts 5 on two sides of the shifting rod 4.

When the device is used, the shifting lever 4 is shifted to the lower part, the shifting lever 4 drives the movable bolt 2 to move upwards, the bolt is inserted into the lock hole 9 on the window frame 8, the pin shaft 5 slides from the left side to the right side of the through groove 6 in the process and then slides to the left side, and the pin shaft is fixed under the action of the elastic pressing strip 7 to prevent the connected shifting lever 4 from loosening. At this moment, the window 3 is limited and can only move towards the closing direction of the window 3, and in the moving process, because the movable bolt 2 is an inclined plane, the movable bolt 2 moves downwards to jump to the lock hole 9 on the next window frame 8, the pin shaft 5 slides to the middle from the left side of the through groove 6 under the action of the elastic pressing strip 7, the driving lever 4 restores the original state and drives the movable bolt 2 to move upwards, and the bolt slides into the lock hole 9 on the window frame 8 to limit the position of the window 3 again.

When the window is not used, the shifting lever 4 is shifted to the upper side, the shifting lever 4 drives the movable bolt 2 to move downwards, the bolt is separated from a lock hole 9 on the window frame 8, the pin shaft 5 is laterally slid to the right side from the left side of the through groove 6 in the process and then slides to the left side, the fixing is carried out under the action of the elastic pressing strip 7, the connected shifting lever 4 is prevented from slipping, and the window 3 can slide on the window frame 8 in parallel at any position.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes made by the present specification can be changed, or directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
