Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings.

Example 1, as shown in figures 1 and 2. A window lock comprises a base 1, wherein a pressing plate 2 and a clamping piece 3 are respectively arranged on the left side and the right side above the base 1, one end of the clamping piece 3 is fixedly clamped with the pressing plate 2, and the other end of the clamping piece 3 is hinged with the base 1 through a hinged shaft; the pressing plate 2 is movably arranged on the base 1 and used for locking the clamping piece 3; a reset piece 4 used for driving the clamping piece 3 to overturn upwards is arranged below the clamping piece 3. The reset piece 4 can adopt a spring, the clamping plate 3 and the base 1 are provided with spring mounting seats, the spring is installed, and elastic potential energy compressed by the spring is used as a driving force.

Referring to fig. 2 specifically, a clamping portion 10 is formed at the joint of the pressing plate 2 and the clamping member 3 in an outward protruding manner, the clamping portion 10 is matched with a clamping groove 11 formed in the clamping member 3, the clamping portions 10 are distributed at two ends of the pressing plate 2 on the same side, and the clamping member 3 is better and more stable in locking performance; and sliding blocks 12 are formed on two sides of the pressing plate 2, and the sliding blocks 12 are matched with sliding block grooves 13 formed in the base 1. The utility model discloses a joint structure uses very conveniently, and the slip setting of cooperation clamp plate 2 only needs the horizontal slip just can realize unblock and locking easy operation during the use.

A plurality of limiting cavities 14 are formed in the base 1, and limiting blocks 15 used for being installed in the limiting cavities 14 are formed in the pressing plate 2. The limiting block 15 is provided with an abutting part 16 in a molding mode, and the abutting part 16 is matched with an abutting block 17 formed in the limiting cavity 14, so that even if a large gap is reserved in an inlet port of the limiting block 15 of the limiting cavity 14, the pressing plate 2 can move smoothly, and the limiting block 15 does not need to be worried to break away from the sliding-out limiting cavity 14.

The base 1 is provided with a mounting cavity 18, a return spring 19 is arranged in the mounting cavity 18, one end of the return spring 19 is connected with a connecting block 20 formed on the pressing plate 2, and the pressing plate 2 can automatically return under the action of the return spring 19 after being unlocked by the technical scheme. The joint on the piece with 2 junctions of clamp plate are provided with bolster 21, and bolster 21 has fabulous shock attenuation cushioning effect for fixing the rectangular shape flexible glue on clamp plate 2, reduces the collision dynamics with screens piece 3 under 2 reset spring 19 effects of clamp plate when the return, and reducing wear prolongs the life of product, has also reduced the noise simultaneously, and user experience feels better.

Referring to fig. 3 in particular, the anti-slip grooves 22 are formed on both sides of the pressing plate 2, when in use, the pressing plate 2 needs to be held by fingers, and the anti-slip grooves 22 are formed on the stressed portion, so that friction is increased, and the use is convenient.

The use principle is as follows: with base 1 direct mount on movable window, when in actual use, to keeping away from 3 directions of screens piece are removed clamp plate 2, clamp plate 2 and the contact site separation of screens piece 3, clamp plate 2 removes the locking to screens piece 3, resets simultaneously under the elastic potential energy effect of piece 4 in screens piece 3 below, resets 4 and upwards promotes screens piece 3, and screens piece 3 upwards overturns around the articulated shaft and forms a screens opening, can be supported when movable window promotes the screens opening part to the biggest clearance of opening of restriction movable window.

Example 2, as shown in fig. 4, 5 and 6. This embodiment is on embodiment 1's basis, base 1 slides and sets up on mounting 5, spout 6 has been seted up on base 1, 5 both sides shaping of mounting have with the slide rail 7 of 6 looks adaptations of spout, base 1 can follow the free slip of 7 directions of slide rail, and in order to avoid base 1 to slide first from mounting 5 to drop simultaneously, all be provided with spacing portion in the one end of mounting 5, the other end does not do the injecing, makes things convenient for the installation of base 1 to dismantle, maintain and change. Even shaping has a plurality of fixed slot 8 on mounting 5, the shaping has and is used for inserting on screens piece 3 fixed slot 8 realizes the spacing fixed part 9 of butt, and fixed part 9 is located the hinged end, and when 2 unblocks of clamp plate, screens piece 3 with the link of clamp plate 2 perks upwards, and the hinged end is downward, fixed part 9 inserts downwards along 8 groove faces in fixed slot, plays the fixed bolster effect, has guaranteed that screens piece 3 supports more stably to movable window. This technical scheme provides a can change the mode in the biggest clearance of opening of movable window, can be according to use needs such as ventilation, move 1 adjustment distance of base in order to adapt to different user demands on slide rail 7, and need not with the utility model discloses pull down and reinstall, once install raise the efficiency, the suitability is wider. The fixed part 9 is formed with an inclined plane contacting with the fixed groove 8, on one hand, the fixed part 9 is inserted more smoothly and conveniently along the inclined groove surface, and on the other hand, the inclined groove also limits the opening angle of the clamping part 3 when in use.

The specific working process of the scheme is as follows: the utility model provides a window lock with adjustable interval will the utility model discloses install on being close to the movable window in the outside, 5 bottoms of mounting have glue can directly paste on movable window, and spout 6 gliding direction on slide rail 7 keeps unanimous with movable window's moving direction. When the device is used, the stress part on the pressure plate 2 is pinched by fingers, the pressure plate 2 moves along the direction of the slide block groove 13 and the direction far away from the clamping piece 3, the clamping part 10 on the pressure plate 2 is separated from the clamping groove 11 formed on the clamping piece 3 below, the clamping end of the clamping piece 3 tilts upwards under the action of the elastic potential energy of the reset piece 4 below without the locking of the pressure plate 2, and the pressure plate 2 returns to the original position under the action of the reset spring 19; when the activity window was close to and the card was gone into to screens piece 3, under the application of force of activity window, screens piece 3 rotated around the articulated shaft, made the adaptability adjustment, and the fixed slot 8 on the shaping was inserted the mounting 5 at the fixed part 9 of articulated end one side simultaneously realizes that the butt is spacing, has restricted the activity window and has continued to remove and increase the clearance of windowing along former direction. In the actual use process, the position of the sliding adjustment base 1 on the fixing piece 5 can meet the requirement according to the requirement of the maximum window opening clearance.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
