[0043] See also Figure 1-Figure 2 The present invention provides a door and window lock, comprising:

[0044] The housing module 1 comprises a first housing 11 and a second housing 12, wherein the first housing 11 and the second housing 12 are spaced apart and respectively installed on the indoor side or the outdoor side of the door and window profile;

[0045] The lock core module 2 is disposed between the first housing 11 and the second housing 12;

[0046] The transmission member 3 is mounted on the lock core module 2;

[0047] The rotating shaft 4 is disposed in the lock core module 2 and can rotate relative to the lock core module 2. The rotating shaft 4 can drive the transmission member 3 to rotate;

[0048] The first locking member 5 is in transmission connection with the transmission member 3 so as to move the first locking member to a locking position or an unlocking position.

[0049] In this embodiment, the door and window lock comprises a housing module 1, a lock core module 2, a transmission member 3, a rotating shaft 4 and a first locking member 5. The installation principle of the entire device is: the transmission member 3 and the rotating shaft 4 are installed on the lock core module 2 to form a transmission member lock core structure (such as Figure 3As shown in the figure, the transmission lock core structure is installed between the first shell 11 and the second shell 12, and connected with the first shell 11 and the second shell 12. The first shell 11 and the second shell 12 are respectively installed on the indoor side or the outdoor side of the door and window profile. Then, a first locking member 5 is arranged on one side corresponding to the position of the transmission member 3 between the first shell 11 and the second shell 12, and the first locking member 5 is in transmission connection with the transmission member 3. Among them, the rotating shaft 4 can rotate relative to the lock core module 2 and drive the transmission member 3 to rotate. The working principle of the whole device is: the user inserts the key into the lock core module 2 from one side (for example, the outside), and twists the key, and then drives the rotating shaft 4 to rotate, and then drives the transmission member 3 to rotate to the specified position, so as to realize the unlocking and locking of the doors and windows. The user can also drive the rotating shaft 4 to rotate from the other side (for example, the inside) through the knob 6 and other components, and then drive the transmission member 3 to rotate to the specified position, so as to realize the unlocking and locking of the doors and windows. The entire device of this embodiment has fewer parts and components, and the installation process is simple. In addition, through the meshing arrangement of the transmission member 3 and the first locking member 5, the process of locking and closing the doors and windows is more labor-saving and convenient.

[0050] In a specific embodiment, Figure 1 , Figure 3-Figure 4 As shown, the transmission member 3 is a gear, which is fixedly connected to the rotating shaft 4, and a rack 52 meshing with the gear is provided on one side of the first locking member 5.

[0051] In this embodiment, a mounting hole 31 is provided on the gear, and the mounting hole 31 is a through mounting hole 31. The rotating shaft 4 passes through the mounting hole 31 and is fixed in the mounting hole 31 to achieve a fixed connection with the gear 3. Specifically, a raised clamping portion can be provided on the outer surface of the rotating shaft 4, and a clamping groove can be provided on the inner surface of the mounting hole 31. The clamping portion is clamped in the clamping groove to achieve relative fixation of the two. Of course, a clamping groove can also be provided on the outer surface of the rotating shaft 4, and a raised clamping portion can be provided on the inner surface of the mounting hole 31 to achieve relative fixation of the two. The mounting hole 31 provides a fixing point, strengthens the connection between the rotating shaft 4 and the gear, prevents the rotating shaft 4 and the gear from loosening or falling off during the rotation process, thereby improving the transmission accuracy of the gear. In addition, if the gear fails, the rotating shaft 4 can be separated from the mounting hole 31, so that the gear can be removed from the rotating shaft 4 so that maintenance personnel can replace or adjust the gear.

[0052] In other specific implementations, one end of the rotating shaft 4 can also be set to a structure with a gear on the outer periphery, that is, the gear and the rotating shaft 4 are set to an integrated structure, and the gear cannot be removed from the rotating shaft 4. This integrated structure can also be installed on the lock core module 2 without affecting the use of the lock core module 2.

[0053] After the gear is fixedly connected to the rotating shaft 4, a rack 52 is set on the side of the first locking member 5 facing the gear, and the rack 52 is meshed with the gear. When the rotating shaft 4 drives the gear to rotate, the gear and the rack 52 rotate in coordination, thereby making the unlocking and locking process of the lock core module 2 more labor-saving.

[0054] Specifically, Figure 1-2 , Figure 5 As shown, it also includes: a knob 6, which is installed on the first housing 11, and one end of the rotating shaft 4 passes through the lock core module 2 and is connected to the knob 6.

[0055] In this embodiment, the first housing 11 is an inner housing, the knob 6 is mounted on the inner housing, and a rotation hole 61 is provided on the side of the knob 6 facing the first housing 11. One end of the rotating shaft 4 passes through the lock core module 2 and the first housing 11 in sequence and is connected to the rotation hole 61, so that the rotating shaft 4 is connected to the knob 6, so that the knob 6 drives the rotating shaft 4 to rotate during the rotation process relative to the lock core module 2, and finally achieves the effect of unlocking or locking the door and window. If the user unlocks or locks on one side of the first housing 11, it can be done by twisting the knob 6 to a specified position. During the twisting process, the knob 6 drives the rotating shaft 4 to rotate, thereby driving the gear to rotate. The setting of the knob 6 is convenient for the user to unlock, and the user only needs to rotate to adjust or control the position of the knob 6.

[0056] Specifically, Figure 2 and Figure 5 As shown, the first housing 11 is provided with a mounting groove 111 for accommodating the knob 6 . In the locked state, the knob 6 is completely accommodated in the mounting groove 111 .

[0057] In this embodiment, a mounting groove 111 is provided on the first shell 11. In the locked state, the knob 6 is completely accommodated in the mounting groove 111. In the unlocked state, the knob 6 can rotate in the mounting groove 111. During the rotation process, the two ends of the knob 6 are located outside the mounting groove 111. The specific unlocking and locking process can refer to the above-mentioned embodiment.

[0058] Specifically, Figure 3-4 , Figure 6 As shown, a lock hole 121 is provided on the second shell 12, and a lock bar 21 is rotatably provided in the lock core module 2, one end of the lock bar 21 is fixedly connected to the other end of the rotating shaft 4, and a lock eye 211 is provided at the other end of the lock bar 21, and the other end of the lock bar 21 is located in the lock hole 121.

[0059] In this embodiment, the second housing 12 is a shell, and the user inserts the key into the keyhole 211, and then twists the key. During the twisting process, the lock bar 21 drives the rotating shaft 4 to rotate as the key is twisted, and then drives the gear and the knob 6 to rotate, so that the user completes the unlocking or locking of one side of the second housing 12. One end of the lock bar 21 and the other end of the rotating shaft 4 can be fixed by a snap-fitting method similar to the aforementioned rotating shaft 4 and the mounting hole 31, or other fixing methods can be used, such as screw connection, nested connection, etc.

[0060] Specifically, Figure 7 As shown, the lock core module 2 includes a lock core housing 22 , and the lock core housing 22 is provided with a mounting position 221 . The gear is located at the mounting position 221 and can rotate at the mounting position 221 .

[0061] In this embodiment, the mounting position 221 is set in the middle area of ​​the lock core housing 22, and the mounting position 221 divides the lock core housing 22 into a left area and a right area. The middle area is connected to both the left area and the right area. The rotating shaft 4 is installed in the left area, and the lock bar 21 is installed in the right area. The other end of the rotating shaft 4 can pass through the left area to enter the mounting position 221 and connect with the gear, and then pass through the mounting position 221 to enter the right area and connect with the lock bar 21. Figure 4 It can be seen that the installation position 221 is essentially an avoidance space or avoidance groove located in the middle area of ​​the lock core housing 22, so that the gear has room to move and rotate on the installation position 221. Since the rotating shaft 4 is horizontally arranged in the lock core housing 22, the rotating plane of the gear is perpendicular to the rotating shaft 4.

[0062] Specifically, two ends of the lock core housing 22 are respectively plugged into the first housing 11 and the second housing 12 .

[0063] In this embodiment, the lock core housing 22 is arranged between the first shell 11 and the second shell 12, and the two ends of the lock core housing 22 are respectively inserted into the first shell 11 and the second shell 12, so that the three form a stable whole, which effectively prevents the lock bar 21, the rotating shaft 4 and the transmission member 3 from rotating, and the lock core module 2 from loosening or breaking during rotation, thereby improving the overall stability.

[0064] In a specific embodiment, Figure 2 , Figure 5-6 As shown, the first shell 11 and the second shell 12 are both provided with connecting holes 13 , and the two ends of the lock core housing 22 are respectively connected to the two connecting holes 13 .

[0065] In this embodiment, a connecting hole 13 is provided at the connecting position of the first shell 11 and the second shell 12 with the lock core shell 22. The contours of the two connecting holes 13 match the two ends of the lock core shell 22, and through holes are provided in both connecting holes 13. This is because the other end of the lock bar 21 is provided with a keyhole 211 and protrudes from the lock bar 21. Therefore, when one end of the lock core module 2 is connected to the second shell 12, a through lock hole 121 (the lock hole 121 is one of the through holes, such as Figure 6 As shown), the keyhole 211 is exposed on the second housing 12, so that the user can insert the key to unlock the lock according to the position of the keyhole 211; and because the rotating shaft 4 needs to be connected to the knob 6, a through shaft hole 112 is opened (the shaft hole 112 is another through hole, such as Figure 5 As shown), the rotating shaft 4 extends out of the first housing 11 and is then firmly connected to the knob 6 through the rotating hole 61, thereby completing the unlocking process.

[0066] Specifically, Figure 2 As shown, the first shell 11 and the second shell 12 are connected via a connecting member 7 .

[0067] In this embodiment, in order to make the connection between the first shell 11 and the second shell 12 more stable, shell holes can be respectively provided on the two shells, and the two ends of the connecting member 7 are respectively connected to the two shell holes. The connecting member 7 can be a spring or a screw. If the connecting member 7 is a screw, the lock core module 2 can be installed between the first shell 11 and the second shell 12 for preliminary fixation, and then the fixing can be strengthened by the connecting member 7; if the connecting member 7 is a spring, the spring can adjust the distance between the two shells according to the length of the two ends of the lock core module 2, so there is no need to wait for the lock core module 2 to be installed before connecting the connecting member 7.

[0068] Specifically, Figure 8 As shown, the first locking member 5 includes a first locking member plate 51, a rack 52 is provided on one side of the first locking member plate 51, and a locking point 53 is provided on the other side of the first locking member plate 51. When the first locking member plate 51 moves, the locking point 53 is synchronously driven so that the locking point 53 cooperates with the lock seat provided on the frame profile to achieve locking.

[0069] In this embodiment, the first locking member 5 includes a first locking member plate 51, a rack 52 and a locking point 53. The rack 52 is composed of a plurality of teeth, and the plurality of teeth are evenly distributed on one side of the first locking member plate 51 close to the gear in the axial direction. The locking point 53 is arranged on the other side of the first locking member plate 51, and the first locking member plate 51 can be installed on the object to be locked (such as doors, windows, profiles, etc.). At the same time, when the first locking member plate 51 moves, it synchronously drives the locking point 53, so that the locking point 53 cooperates with the lock seat arranged on the frame profile to achieve locking. After the first locking member 5 is installed, according to the position of the rack 52, the whole composed of the above-mentioned embodiment (i.e., the whole composed of the transmission member 3, the rotating shaft 4, the lock core module 2 and the housing module 1) is installed, and the gear is meshed with the plurality of teeth, so that the door and window lock can operate normally. In other specific embodiments, the rack 52 can also be replaced with a gear, and the gears can also be meshed with each other to achieve the same effect.

[0070] like Fig. 9 As shown, the embodiment of the utility model further provides a door and window 8, including a frame assembly and a sash assembly, and the frame assembly and the window assembly are connected by the door and window lock as described above.

[0071] The door and window lock of this embodiment is achieved by installing the first locking component 5 on the frame assembly and the fan assembly of the door and window 8, and then fixing the assembled whole with connecting parts such as screws. The installation process is simple, and the aesthetic and firm installation of the door and window is achieved.

[0072] 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.
