Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and fig. 2, a door and window lock provided in an embodiment of the present invention includes a housing 1, a handle 8, a slider 11, and a transmission member 10, where the housing 1 has a handle slot, the handle 8 can be hidden in the handle slot, a front end of the handle 8 can be rotatably connected to the housing 1 through a handle shaft 7, an elastic member 12 for making the handle 8 bounce relative to the housing 1 is disposed between the handle 8 and the housing 1, the elastic member 12 can be a torsion spring, the slider 11 is slidably connected to the housing 1, one end of the transmission member 10 is rotatably connected to the handle 8, the other end of the transmission member 10 is rotatably connected to the slider 11, an idle stroke structure for making the slider 11 rest relative to the housing 1 when the handle 8 bounces a set angle is disposed between the slider 11 and the transmission member 10, that is, in an initial stage, the elastic member 12 (torsion spring) can make the handle 8 bounce a certain angle, when the handle 8 is bounced by a certain angle (as shown in fig. 3), the sliding block 11 can be kept static, so that the bouncing force of the handle 8 can be very small, the hand is not easy to hurt, the handle 8 folded on the shell 1 is also not easy to be locked by stress, the user is easy to operate, and the user experience is good.

Specifically, the idle stroke structure includes a stroke groove 111 disposed in the slider 11, the stroke groove 111 may be disposed along a sliding direction of the slider 11, and the transmission member 10 is connected to the slider 11 through a sliding shaft 9 slidably disposed in the stroke groove 111. The transmission member 10 is rotatably connected to the slide shaft 9. When the handle 8 is in idle stroke, the sliding shaft 9 can slide and rotate in the stroke groove 111.

Or, as an alternative, the idle stroke structure includes a stroke groove disposed in the transmission member 10, and the sliding block is connected to the transmission member 10 through a sliding shaft slidably disposed in the stroke groove, so that the function that the handle 8 is bounced by a certain angle and the sliding block 11 is stationary can also be realized.

Specifically, the housing is provided with a locking mechanism for locking and releasing the rear end of the handle 8, and the locking mechanism can be locked at the rear end of the handle 8, so that the handle 8 can be kept in a folded state in the handle groove.

Specifically, the locking mechanism is a button 6 rotatably connected to the housing 1, the front part of the button 6 is clamped at the rear end of the handle 8, and the rear part of the button 6 is provided with a return elastic part 4; namely, a return elastic member 4 is provided between the rear portion of the push button 6 and the housing 1. The button 6 may be of a rocker type, and the middle portion of the button 6 is rotatably connected to the housing 1. The rear end of the handle 8 can be set to be an inclined plane, or the front end face of the button 6 is set to be an inclined plane, when the rear end of the handle 8 is downward, the front end of the button 6 can be automatically clamped at the front end of the button 6, when the rear portion of the button 6 is pressed downward, the front end of the button 6 is lifted upward to release the locking of the rear end of the handle 8, the handle 8 immediately bounces upward for a certain angle under the action of the elastic piece 12 (torsion spring), and the elastic piece 12 (torsion spring) does not need to drive the sliding block 11, so that the elastic force of the elastic piece 12 (torsion spring) can. The user can easily operate the handle 8 (as shown in fig. 4) to slide the slider 11 to unlock the door and window. The handle 8 can also be folded by reverse rotation (as shown in fig. 5 and 6).

In particular, the return elastic member 4 is a spring.

Specifically, the housing 1 is further provided with a lock cylinder structure for locking the button 6, the lock cylinder structure comprises a lock cylinder piece 3 which can be unlocked by a key 5 and a lock cylinder slide 2 which is connected to the lock cylinder piece 3 and can be driven by the lock cylinder piece 3 and moved to the position below the button 6, and when the lock cylinder slide 2 is moved to the position below the button 6, the rear part of the button 6 cannot be pressed down, and the locking of the handle 8 cannot be released.

Specifically, the front end of the casing 1 is provided with an upper plug cushion block 13, an upper plug 15 and a handle spring 14, and two ends of the handle spring 14 respectively abut against the upper plug 15 cushion block 13 and the upper plug 15. One end of the cushion block 13 of the upper plug 15 faces the sliding block 11.

Specifically, the door and window lock is a hidden lock; the idle stroke structure enables the idle stroke angle of the handle 8 to be 30-40 degrees, the maximum opening angle of the handle 8 is larger than 90 degrees, and the sliding stroke of the sliding block 11 is larger than 15 mm. In this embodiment, the idle stroke structure makes the idle stroke angle of the handle 8 bouncing up 34 degrees, the maximum opening angle of the handle 8 is 94 degrees, and the sliding of the slider 11 is 16.5 mm. Of course, the idle stroke structure enables the idle stroke angle of the handle 8, the maximum opening angle of the handle 8 and the sliding stroke of the slider 11 to be set according to actual conditions.

According to the door and window lock provided by the embodiment of the invention, the handle 8 can be bounced by the elastic part 12 (torsion spring) at a certain angle so as to be convenient for a user to hold and operate, and the sliding block 11 can be kept static when the handle 8 bounces at a certain angle, so that the bouncing force of the handle 8 can be very small, the hand is not easy to be injured, the handle 8 folded on the shell 1 is not easy to be locked by force, the operation is easy for the user, and the user experience is good.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents or improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
