Detailed Description

The invention provides a window limiter, which is described in further detail below by referring to the accompanying drawings and embodiments in order to make the purpose, technical scheme and effect of the invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It should be noted that the front surface of the base in the present application refers to the mounting plane of the adjustment rod, and the other surfaces of the base are defined one by one with the mounting plane of the adjustment rod as the front surface as the reference.

Referring to fig. 1-3, the present invention provides a window stop, which comprises a safety ring 1, two positioning locks 2 sleeved on the safety ring 1; the positioning lock 2 comprises a base 21, a sliding block 22, a first fixing block 23, a second fixing block 24 and an adjusting rod 25, wherein the sliding block 22, the first fixing block 23, the second fixing block 24 and the adjusting rod are connected to the base 21; the perpendicular rigid coupling of first fixed block 23 is in the one end of base 21 bottom surface, base 21 is equipped with first through-hole 21a and second through-hole 21b, run through base 21 about first through-hole 21a, slider 22 sets up in first through-hole 21a, its one side and the perpendicular rigid coupling of second fixed block 24 that is close to with first fixed block 23, first

fixed block

23 and 24 parallel arrangement of second fixed block for it is fixed to the window centre gripping, the front of base 21 still is equipped with second through-hole 21b, second through-hole 21b communicates the front and the first through-hole 21a of base 21, adjusts pole 25 and sets up in second through-hole 21b for adjust the position of slider 22 in first through-hole 21 a.

When the limiting stopper is installed on a casement window, the first fixing block and the second fixing block of one positioning lock are clamped on a window frame on one side of the opened window, the adjusting rod is screwed into the second through hole, the adjusting rod drives the sliding block to move towards the first fixing block, so that the clamping space between the first fixing block and the second fixing block is reduced until the window frame is locked, and then the other positioning lock is fixed on the window frame on the other side of the window, so that the opening size of the window can be fixed. When the positioning lock is disassembled, the positioning lock can be disassembled only by screwing the adjusting rod out of the second through hole, pushing the sliding block to be away from the first fixing block and increasing the distance between the first fixing block and the second fixing block. When the limiting stopper is used for a push-pull window, the safety lock is fixed on a window frame sliding rail, the back surface of the base abuts against the window, the position of the window is fixed, and the installation mode and the disassembly mode of the limiting stopper are the same as those of the limiting stopper installed on a flat-open window. The stopper is convenient to install and detach, does not need tools, and is high in practicability.

Further, the middle of one side of the second fixing block 24 connected with the slider 22 is provided with an installation groove 24a, the installation groove 24a is matched with the side wall formed by the first through hole 21a and the left side surface of the base 21, and the second fixing block 24 is clamped on the base 21 and is fixedly connected with the slider 22. The lateral wall joint that first through-hole and the left surface of base formed is in the mounting groove, and the slider drives the second fixed block and removes on the base, adjusts and the first fixed block between the distance, realizes the fixed of the window frame of different thickness.

Specifically, the length of the slider 22 is longer than the depth of the first through hole 21a, and is equal to the length of the second fixing block 24, so that the second fixing block can be clamped on the base and fixedly connected with the slider, and the slider can drive the slider to move. The thickness of the sliding block is matched with the first through hole, and the width of the sliding block is smaller than the length of the first through hole.

Preferably, the adjusting rod 25 is T-shaped and includes a handle 25a and an adjusting portion 25b, one end of the adjusting portion 25b is fixed in the middle of the handle 25a, the other end abuts against the slider 22, and the adjusting portion 25b is provided with an external thread. The T-shaped adjusting rod is convenient to rotate, can be screwed and loosened without tools, and is convenient to use.

Further, the second through hole 21b is provided with an internal thread adapted to an external thread of the adjusting portion 25b of the adjusting lever 25. The adjusting rod is connected with the second through hole through threads, so that the adjusting rod can be fixed when screwed into the second through hole at different depths, and children cannot take out the adjusting rod easily, and the safety is improved.

Further, the length of the adjustment portion 25b of the adjustment lever 25 is longer than the depth of the second through hole 21 b.

Preferably, the second through hole 21b is a circular hole, and penetrates through the middle between the front surface of the base 21 and the first through hole 21 a. The length that the slider extrudes both sides of base is isometric, and the round hole is convenient for rather than the regulation pole rotation that matches, the second through-hole sets up in the middle of making the regulating lever implement the centre of slider to the push action of slider, and the atress is even, and the slider removes more smoothly, laborsaving.

Specifically, the base 21 is further provided with a third through hole 21c penetrating through the upper and lower surfaces of the base, and the safety ring 1 penetrates through the third through holes 21c on the bases 21 of the two positioning locks 2 to connect the two positioning locks 2.

In one embodiment, the stop is made of 304 stainless steel. The 304 stainless steel has high toughness and good corrosion resistance, and can ensure the safety of the safety lock and prolong the service life of the safety lock when used for preparing the safety lock.
