[0032] Combination Figure 1 and Figure 2The utility model provides an automatic latching structure, which is applied to sliding doors and windows. The sliding doors and windows include an external transmission component (not shown in the figure). The automatic latching structure includes: a base 1, which is provided with a receiving cavity 11 along the length direction and a cavity opening 12 connected to the receiving cavity 11; a sliding component 2, which is slidably arranged in the receiving cavity 11; the sliding component 2 includes a slider 21 and a handle 22, the slider 21 is slidably arranged in the receiving cavity 11, and is transmission-connected with the external transmission component. When the slider 21 slides, the automatic latching structure is realized. The handle 22 is rotatably connected to the slider 21; when the handle 22 is rotated in a first direction, it can be rotatably accommodated in the accommodating cavity 11 and exposed in the cavity opening 12; when the handle 22 is rotated in a second direction, it can be rotatably extended out of the cavity opening 12 and partially exposed outside the cavity opening 12; wherein, when the handle 22 is accommodated in the accommodating cavity 11, the handle 22 can be pressed from the cavity opening 12; when the handle 22 is rotated and extended out of the cavity opening 12, the portion of the handle 22 exposed outside the cavity opening 12 (such as Figure 4 As shown), the linkage slider 21 slides in the direction of unlocking the doors and windows.

[0033] In this embodiment, the base 1 is in the shape of a rectangular parallelepiped, and the slider 21 is adapted to the shape of the accommodating cavity 11, so that the slider 21 can slide to a first position and a second position in the accommodating cavity 11. When the slider 21 is in the first position, the slider 21 realizes the locking function of the door and window; when the door and window need to be unlocked, the slider 21 is slid to the second position by pressing the handle 22, so that the slider 21 is disengaged from the door and window, thereby unlocking the door and window.

[0034] Specifically, when the handle 22 is accommodated inside the accommodating cavity 11, the base 1 can be exposed through the cavity opening 12. When the handle 22 needs to be pressed, the handle 22 is pressed at the cavity opening 12, and the handle 22 drives the slider 21 to slide to the second position, thereby unlocking the doors and windows; or, when the handle 22 rotates in the accommodating cavity 11, part of the handle 22 can be extended to the outside of the base 1 through the cavity opening 12. Based on this, when the handle 22 needs to be pressed, the handle 22 is pressed to extend to the outside of the base 1, and the slider 21 is driven to slide to the second position, thereby unlocking the doors and windows.

[0035] In this embodiment, by combining two ways of unlocking doors and windows on the same handle 22, compared with the relatively single lock opening method in the prior art, it has better operational flexibility and can meet people's higher requirements for touch locks.

[0036] In one embodiment, a groove 211 is formed on the slider 21 . The groove 211 extends along the length direction of the accommodating cavity 11 and corresponds to the cavity opening 12 . The handle 22 is rotatably connected in the groove 211 .

[0037] In this embodiment, the groove 211 provides an installation space for the handle 22, so that the handle 22 can be installed in a contained manner in the base 1, thereby improving the structural compactness of the installation of the slider 21 and the handle 22; wherein, the groove 211 corresponds to the cavity opening 12, so that the exposed handle 22 can be seen from the cavity opening 12, and then the user can directly press the handle 22 to slide the handle 22 in the direction of unlocking the door or window; or, when the handle 22 rotates in the groove 211, it can be ensured that part of the handle 22 extends out of the cavity opening 12.

[0038] In this embodiment, the volume of the handle 22 is smaller than the volume of the groove 211, so that there is an operating space between the handle 22 and the groove 211, which is convenient for the user to directly press the handle 22 exposed in the cavity 12, and to facilitate the user to rotate the handle 22 in the groove 211 so that the handle 22 extends out of the cavity 12.

[0039] In one embodiment, a mounting portion 212 is provided in the groove 211; one end of the handle 22 is hinged to the mounting portion 212; when the handle 22 rotates in a first direction, the other end of the handle 22 is accommodated in the accommodating cavity 11; when the handle 22 rotates in a second direction, the other end of the handle 22 rotates out of the cavity 12 and is located outside the base 1.

[0040] In this embodiment, the mounting portion 212 includes a first mounting block and a second mounting block relative to each other; one end of the handle 22 is hinged to the first mounting block and the second mounting block through a rotating shaft 23; an arc-shaped avoidance opening for avoiding one end of the handle 22 is provided between the first mounting block and the second mounting block. When the handle 22 rotates, the arc-shaped avoidance opening can accommodate the space required for the rotation of one end of the handle 22, so that the overall structure is more compact and the space utilization rate is higher, so as to facilitate miniaturization.

[0041] In the present embodiment, when the handle 22 is rotated to the first angle in the first direction and the other end of the handle 22 is received in the accommodating cavity 11, the handle 22 is flush with the extension direction of the groove 211 and is completely fitted in the groove 211; and one end of the handle 22 serves as a rotating connection end. In order to facilitate the user to operate the handle 22 exposed in the cavity 12, the height of one end of the handle 22 is set to be flush with the depth direction of the groove 211, thereby improving the convenience of pressing the handle 22.

[0042] In this embodiment, when the handle 22 is rotated to the second angle in the second direction, the other end of the handle 22 will be perpendicular to the bottom of the groove 211 and extend out of the cavity 12, so that when the handle 22 is pressed, the slider 21 is unlocked by pressing the part of the handle 22 extending out of the cavity 12.

[0043] It should be noted that the first angle and the second angle are perpendicular to each other, so as to ensure that the handle 22 can be in two different states after rotation, that is, the other end of the handle 22 is located in the cavity opening 12 or extends out of the cavity opening 12.

[0044] In one embodiment, a first operating portion 221 and a second operating portion 222 are provided on the handle 22. When the handle 22 is accommodated in the accommodating cavity 11, the first operating portion 221 corresponds to a direction away from unlocking the door and window; when the handle 22 is rotated and extended out of the cavity 12, the second operating portion 222 corresponds to a direction away from unlocking the door and window.

[0045] In this embodiment, in the first unlocking operation mode, the first operating part 221 is located at one end of the handle 22. When the door and window need to be unlocked, the handle 22 can be rotated in the first direction to the first angle so that the first operating part 221 corresponds to the direction away from the unlocked door and window, and then the first operating part 221 is pressed to link the slider 21 to unlock, thereby improving the convenience of pressing the handle 22; in the second unlocking operation mode, the second operating part 222 is located at the other end of the handle 22. When the door and window need to be unlocked, the handle 22 can be rotated in the second direction to the second angle so that the second operating part 222 corresponds to the direction away from the unlocked door and window, and then the second operating part 222 is pressed to link the slider 21 to unlock, thereby improving the convenience of pressing the handle 22.

[0046] When the first operating portion 221 or the second operating portion 222 is correspondingly in a direction away from unlocking the door or window, the first operating portion 221 and the second operating portion 222 are both perpendicular to the bottom surface of the groove 211 to improve the convenience of pressing the handle 22 .

[0047] See also Figure 3 As shown, in one embodiment, one end of the slider 21 is limited to one end of the base 1, and the other end of the slider 21 is elastically connected to the other end of the base 1 along the direction of unlocking the door and window.

[0048] In this embodiment, when the slider 21 slides in the locking direction to the first position, it is limited to one end of the base 1, thereby avoiding the slider 21 from sliding too far and ensuring that the slider 21 can be stably locked in the first position; when the slider 21 is forced to slide in the unlocking direction, the slider 21 will be affected by the elastic force at the other end of the base 1, and the elastic force can drive the slider 21 to reset, and finally slide to the first position.

[0049] In a more specific embodiment, a limit member 13 is provided in one end of the base 1, and when the slider 21 slides to the first position along the locking direction, the limit member 13 can be abutted, thereby ensuring that the slider 21 stably stops at the first position to achieve locking; a fixing portion 14 is provided at the other end of the base 1, and a first elastic member 15 is provided on the fixing portion 14. The slider 21 is elastically connected to the fixing portion 14 through the first elastic member 15, and when the slider 21 slides to the second position along the unlocking direction, the first elastic member 15 can be compressed to achieve the slider 21 reset function.

[0050] In this embodiment, the limit member 13 is a limit screw, which is passed through the width direction of the base 1. When the slider 21 slides to the first position along the length direction of the accommodating cavity 11, it can be lower than the limit screw to ensure the stability of the slider 21 stopping at the first position.

[0051] In this embodiment, the fixing portion 14 is fixed to the other end of the base 1. When the slider 21 slides in the unlocking direction, the slider 21 can squeeze the first elastic member 15 in the direction of the fixing portion 14 and move it to the second position, so that the first elastic member 15 is continuously subjected to force. When the slider 21 is not subjected to external force, the elastic force of the first elastic member 15 drives the slider 21 to return to the first position, thereby ensuring the automatic return of the slider 21 and the automatic locking function of the latch of this embodiment.

[0052] The first elastic member 15 may be one of a spring, a compression spring and a spring sheet.

[0053] In one embodiment, the sliding assembly 2 further includes a buffer member 24 . The buffer member 24 is disposed at one end of the sliding block 21 facing the locking direction and is opposite to the limiting member 13 .

[0054] In this embodiment, when the slider 21 slides to the first position in the locking direction, the slider 21 will collide with the limit member 13, and the limit member 13 limits the continued sliding of the slider 21. A buffer member 24 is arranged on the slider 21. When the slider 21 is limited by the limit member 13, the buffer member 24 can reduce the impact force between the slider 21 and the limit member 13, thereby protecting the slider 21 and the limit member 13 from wear and tear, and improving the service life of the slider 21.

[0055] The buffer member 24 may be made of a deformable material such as sponge or rubber.

[0056] In one embodiment, a telescopic component 16 is further included, and the telescopic component 16 includes a telescopic portion 161 and a second elastic member 162. The telescopic portion 161 is limited inside one end of the base 1 and partially extends outside one end of the base 1. One end of the second elastic member 162 is connected to the telescopic portion 161, and the other end of the second elastic member 162 is connected to the limiting member 13.

[0057] In this embodiment, in the initial state, part of the telescopic portion 161 extends out of one end of the base 1. By pressing the telescopic portion 161, the telescopic portion 161 can be retracted into the inside of the base 1 to shorten the length of the entire automatic latch structure. Therefore, when the entire automatic latch structure is installed in the cavity of the door or window, the telescopic portion 161 can be pressed so that the entire automatic latch structure can enter the cavity of the door or window after being shortened. After entering the cavity, the telescopic portion 161 is reset due to the elastic force of the second elastic member 162, thereby improving the convenience of latch installation and the stability after installation.

[0058] In one embodiment, a locking member 3 is further included. The locking member 3 is arranged at the end of the base 1 facing the unlocking direction. The base 1 is provided with a toggle groove 17 (such as Figure 2 As shown in the figure, an external tool can slide the locking member 3 in a direction perpendicular to the switch lock through the toggle groove 17, and when the locking member 3 slides in the sliding direction, it can prevent the slider 21 from sliding in the unlocking direction.

[0059] In this embodiment, when the slider 21 slides in the locking direction, one end of the slider 21 is limited by the limit piece 13, and the locking piece 3 has a hole core 311, which is exposed to the outside of the base 1 through the toggle slot 17, wherein the external tool can be a small object with a small head, and the locking piece 3 is driven to slide in a direction perpendicular to the switch lock by inserting the external tool into the hole core 311, so that the locking piece 3 blocks the other end of the slider 21, thereby preventing the other end of the slider 21 from moving in the unlocking direction; such a configuration fixes the slider 21 in the accommodating cavity 11 of the base 1, so that the slider 21 cannot slide, thereby ensuring the safety of the slider 21 after locking the door and window.

[0060] Among them, the locking member 3 includes a sliding portion 31 and a locking portion 32, the locking portion 32 is inserted into the fixed portion 14, and the sliding portion 31 is slidably assembled on the fixed portion 14 along a direction perpendicular to the switch lock. When the sliding portion 31 slides, the locking portion 32 can prevent the slider 21 from sliding; more specifically, a slide rail 141 is provided on the fixed portion 14 along a direction perpendicular to the switch lock, and a slide groove 312 is provided on the sliding portion 31. The sliding portion 31 is slidably assembled on the slide rail 141 through the slide groove 312 to realize the sliding of the locking member 3.

[0061] In one embodiment, an escape groove 25 is provided on one end of the slider 21 facing the unlocking direction along the switch lock direction, and when the locking member 3 slides to the escape position or the locking position in the sliding direction, it can correspond to or be misaligned with the escape groove 25.

[0062] In this embodiment, when the slider 21 slides in the unlocking direction, the locking member 3 is slid in the sliding direction to the avoidance position so that the locking member 3 corresponds to the avoidance groove 25, thereby preventing the locking member 3 from blocking the sliding of the slider 21; and when it is necessary to block the slider 21 from sliding in the unlocking direction, the locking member 3 is slid in the sliding direction to the locking position so that the locking member 3 and the avoidance groove 25 are misaligned, thereby making the locking member 3 and the slider 21 physically abut against each other, thereby achieving the locking member 3 being able to block the movement of the slider 21.

[0063] The embodiment of the utility model further provides a sliding door and window, comprising the automatic latching structure as described above.

[0064] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
