When the door and window is pushed to enable the lock tongue 20 to be embedded into the corresponding locking notch by overcoming the elastic force of the first elastic piece 31 and the second elastic piece 32, the first lock tongue 21 and the second lock tongue 22 can be clamped into two sides of one lock tongue 20, and the third lock tongue 23 and the fourth lock tongue 24 can be clamped into two sides of the other lock tongue 20, so that the door and window can be locked. When the handle cover 40 is pulled, the first locking piece 21 and the second locking piece 22 can be opened, and the third locking piece 23 and the fourth locking piece 24 can be opened, so that unlocking of doors and windows can be realized.
A coil spring may be further installed between the rear of the handle cover 40 and the bottom wall of the accommodating chamber 11, and the handle cover 40 may be quickly and reliably restored to the original position by the elastic force of the coil spring.
The child lock is installed to the bottom of lock body 10, and child lock is including rotating the lock post 51 of installing in lock body 10 bottom, and hexagonal recess has been seted up to the one end face of lock post 51 and this terminal surface exposes the front of lock body 10, is provided with slider 52 at the one end face border that lock post 51 kept away from the hexagonal recess, and slider 52 is cylindric. A locking block 50 is slidably mounted at the bottom of the accommodating cavity 11 along the left-right direction, a vertical block is integrally formed at the right end of the locking block 50 and at one side close to the locking column 51, a guide groove 53 in the vertical direction is formed at one side of the vertical block close to the locking column 51, and a sliding block 52 is embedded in the guide groove 53.
Referring to a and b of fig. 5, when the child lock is not in use, the locking piece 50 is located at the lower right side of the first locking piece 21, and the locking piece 50 does not obstruct the normal rotation of the first locking piece 21, so that the first locking piece 21 can normally rotate to unlock. Referring to c in fig. 5, when the child lock is needed, the locking piece 50 is pushed to move from the rightmost position to the leftmost position by the sliding block 52 when the locking post 51 is rotated by half a turn by using a tool from the front of the lock body 10, so that the locking piece 50 is positioned below the first locking piece 21, the locking piece 50 is blocked below the first locking piece 21, the first locking piece 21 cannot be rotated anticlockwise, unlocking cannot be achieved, and thus the effect of preventing the child from being opened by mistake can be achieved, and simultaneously, the first locking piece 21 can be prevented from being pried from outside the lock body 10.
An elastic ring 54 is arranged on the outer periphery of the lock cylinder 51, the elastic ring 54 can be made of plastic with good elasticity, positioning blocks 55 protruding outwards are respectively arranged on two sides of the outer periphery of the elastic ring 54, and the positioning blocks 55 are semi-cylindrical. A positioning groove 56 is formed in the bottom wall of the accommodating groove. The inner wall shape of the positioning groove 56 is matched with the outer shape of the positioning block 55. The elastic ring 54 is provided with elastic through grooves 57 at two sides corresponding to the positioning blocks 55, the elastic through grooves 57 penetrate through the elastic ring 54, the cross section of the elastic through grooves 57 is isosceles triangle, and the vertex angle is corresponding to the positioning blocks 55. When the lock cylinder 51 is rotated to make the two positioning blocks 55 respectively embedded in the positioning grooves 56, the sliding blocks 52 respectively correspond to the leftmost and rightmost positions, even if the locking blocks 50 are respectively positioned at the leftmost and rightmost positions, thereby realizing the stability and positioning of the locking position and the unlocking position of the child lock.
A shielding cover 60 is installed in front of the lock body 10 and above the handle cover 40, and both sides of the top of the shielding cover 60 are respectively rotatably installed on the left and right inner side walls of the accommodating cavity 11.
