[0054] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the present invention, so as to fully understand the purpose, scheme and effect of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other without conflict. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0055] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature, or it may be indirectly fixed or connected to the other feature. In addition, the descriptions of up, down, left, right, etc. used in the present invention are only relative to the relative positional relationship of the components of the present invention in the drawings.

[0056] Reference Figures 1 to 14 , an actuator 100 of a door and window lock includes a fixing seat 110, a driving gear 120 and a sliding strip 130.

[0057] Among them, Figure 2 and Figure 3As shown, the fixing seat 110 is used to be fixedly connected to the base 300, and the fixing seat 110 is provided with a slide groove 111 and a gear receiving groove 112 connected to the slide groove 111. The slide groove 111 is used to install the sliding insert 130, and the slide groove 111 is vertically arranged. The length of the sliding insert 130 can be greater than the slide groove 111. The gear receiving groove 112 is used to install the driving gear 120 and allow it to rotate, and is a cylindrical groove. The fixing seat 110 is divided into two halves, left and right, which are combined to form the above-mentioned slide groove 111 and gear receiving groove 112.

[0058] like Figure 1 As shown, the base 300 mentioned here can be a frame profile of a door or window, or can be other parts where door and window locks need to be installed.

[0059] like Figure 3 and Figure 4 As shown, the driving gear 120 is rotatably mounted in the gear accommodating groove 112. The driving gear 120 includes a first gear portion 121 and a second gear portion 122 arranged side by side, the first gear portion 121 is provided with a protruding first gear tooth 1211, the second gear portion 122 is provided with a protruding second gear tooth 1221, the first gear tooth 1211 and the second gear tooth 1221 are staggered at an angle, and the driving gear 120 is also provided with a rotating connecting portion 123 for connecting with a rotating driving member. In short, the driving gear 120 is a double gear. Compared with the method of dividing into two gears for cooperative driving, the driving gear 120 of the present invention is more convenient to assemble, has high assembly efficiency and is less prone to errors.

[0060] like Figures 1 to 3 and Figure 5 As shown, the sliding insert 130 can be slidably inserted in the slide groove 111, and one side of the sliding insert 130 is provided with a first rack 131 and a second rack 132 that match and mesh with the first gear 1211 and the second gear 1221 respectively along the direction of the slide groove 111.

[0061] Based on the above structure, after the rotary drive member is connected via the rotary connection portion 123, the driving gear 120 can be driven to rotate by the rotation of the rotary drive member. Since the gear teeth and the rack are meshed, the slide groove 111 can be driven to slide up and down.

[0062] The rotating driving member can be a handle 200 of the lock, on which an output shaft 201 is provided, and the output shaft 201 is connected to the driving gear 120. When the handle is turned, the output shaft 201 also rotates, thereby driving the driving gear 120 to rotate together, driving the sliding strip 130 to slide up and down, and performing locking and unlocking actions.

[0063] The rotating connection part 123 can be set as a hole, which is circumferentially fixedly connected to the output shaft 201 of the rotating drive member, or the rotating connection part 123 can be set as a shaft, which is circumferentially fixedly connected to the output shaft 201 of the rotating drive member through a coupling.

[0064] Specifically, Figure 3 As shown, the rotating connection part 123 is a shaft connection hole 1231, and the shaft connection hole 1231 is used to be fixedly connected to the output shaft 201 of the rotating driving member in the circumferential direction; the side wall of the gear receiving groove 112 is provided with a shaft through hole 118 for the output shaft 201 to pass through. The output shaft 201 is usually a regular hexagonal column, and the shape of the shaft connection hole 1231 can be a regular hexagon, which can be fixed to the output shaft 201 in the circumferential direction, and when the output shaft 201 rotates, the two do not slip.

[0065] Or, if Fig.13 and Fig.14 As shown, the rotary connection part 123 is a shaft column 1232 protruding from the end face of the driving gear 120, the shaft column 1232 is coaxially arranged with the driving gear 120, the shaft column 1232 is circumferentially fixedly connected with the output shaft 201, and the side wall of the gear receiving groove 112 is provided with a shaft through hole 118 for the output shaft 201 or the shaft column 1232 to pass through. In actual use, the shaft column 1232 and the output shaft 201 of the handle 200 can be connected together by a coupling 204, and the rotation of the handle 200 is transmitted to the driving gear 120 through the coupling 204, driving the driving gear 120 to rotate together, thereby driving the sliding strip 130 to slide up and down to perform a locking or unlocking action. The cross section of the shaft column 1232 is usually set to a regular hexagon, and the cross section of the output shaft 201 is also set to the same regular hexagon. The coupling 204 is provided with a coupling through hole 2041, and the cross section of the coupling through hole 2041 is also the same regular hexagon. The shaft column 1232 and the output shaft 201 are both inserted into the coupling through hole 2041 to achieve circumferential fixed connection.

[0066] The driving gear 120 of the present invention is provided with a first gear portion 121 and a second gear portion 122, which are staggered at an angle and can simultaneously mesh and rotate with the first rack 131 and the second rack 132 of the sliding insert 130 during rotation. The two cooperate to drive the sliding insert 130 to slide, and can complement each other's rotation drive interval, thereby reducing the sense of jamming when the sliding insert 130 slides, making it slide more smoothly and improving the user experience.

[0067] Preferably, if Figure 4As shown, the first gear teeth 1211 and the second gear teeth 1221 are the same gear teeth, which are only staggered by an angle and do not overlap, so that the rotation between the two can maintain the same driving speed for the sliding insert 130, ensuring that the sliding insert 130 slides up and down at a uniform speed. Correspondingly, the first rack 131 and the second rack 132 are also staggered by an angle.

[0068] Among them, Figure 4 As shown, the driving gear 120 is integrally formed, and no other connection is required between the two, which is more stable and reliable when used.

[0069] Preferably, in order to facilitate the installation and fixation of the actuator 100 and the profile of the door and window, Figure 3 , Figures 6 to 9 As shown, the actuator 100 of the door and window lock also includes a clamping structure 140. The clamping structure 140 includes a first clamping block 141, a second clamping block 142 and a push-off member 143.

[0070] Among them, Figure 3 As shown, the fixing seat 110 is provided with a clamping block receiving groove 113 which is perpendicular to the sliding groove 111 , and a groove 114 is provided on one side of the clamping block receiving groove 113 .

[0071] like Figure 7 and Fig. 9 As shown, the first clamp block 141 and the second clamp block 142 are both arranged in the clamp block accommodating groove 113 and can slide along the clamp block accommodating groove 113; the first clamp block 141 is provided with a first hook 1411 extending out of the slot 114; the second clamp block 142 is provided with a second hook 1421 extending out of the slot 114, and the first hook 1411 and the second hook 1421 are in opposite directions; the push-off member 143 is arranged between the first clamp block 141 and the second clamp block 142, and is used to push the first clamp block 141 and the second clamp block 142 to the two ends of the clamp block accommodating groove 113 respectively.

[0072] Based on the above structure, the hooks of the first clamp block 141 and the second clamp block 142 are extended, and the hooks can be fixed with the groove 301 of the frame profile of the door and window. The groove 301 of the existing profile is C-shaped, and the hooks can be hooked on the notch edge of the C-shaped groove 301 for fixing, and the hooked state is maintained under the action of the push-off member 143 to prevent the fixing seat 110 from separating from the profile. During installation, the distance between the first clamp block 141 and the second clamp block 142 can be reduced first so that they can be installed in the groove 301, and then fixed to the profile under the push-off of the push-off member 143.

[0073] After the clamping structure 140 is fixed with the groove 301, the front-back and left-right positions of the fixing seat 110 on the profile are fixed, and the upper and lower positions can be fixed by means of screws, positioning pins or positioning columns.

[0074] like Figure 7 and Fig. 9 As shown, in order to make the push-off member 143 maintain a stable connection with the first clamp block 141 and the second clamp block 142 to avoid dislocation and separation, the first clamp block 141 and the second clamp block 142 are respectively provided with a first connection positioning groove 1412 and a second connection positioning groove 1422 for connecting with the push-off member 143 on the facing surfaces. After the first connection positioning groove 1412 and the second connection positioning groove 1422 are connected to the push-off member 143, the push-off member 143 can be prevented from being dislocated and separated.

[0075] It is understandable that the push-off member 143 can adopt a variety of structures, but the following three structures have the advantages of easy installation, stable connection, and not easy to fall off.

[0076] One of the structures is: Figure 6 and Figure 7 As shown, the push-off member 143 is an elastic member 1431, and two ends of the elastic member 1431 are respectively in contact with the first clamping block 141 and the second clamping block 142. More specifically, the elastic member 1431 is a compression spring.

[0077] During installation, the first clamp block 141 and the second clamp block 142 can be brought close to each other to compress the elastic member 1431 so that the first clamp block 141 and the second clamp block 142 can be placed in the groove 301 of the profile, and then the elastic member 1431 can be released. Under the elastic force of the elastic member 1431, the first clamp block 141 and the second clamp block 142 are separated and respectively hooked on the notches of the groove 301 of the profile to complete the installation.

[0078] Preferably, if Figure 7 As shown, the first hook 1411 and the second hook 1421 are provided with a guide surface 1440 facing the notch of the groove 301, so that during installation, the first hook 1411 and the second hook 1421 are inserted into the groove 301. Under the action of the guide surface 1440, the first hook 1411 and the second hook 1421 automatically approach and compress the elastic member 1431, and finally the first hook 1411 and the second hook 1421 are inserted into the groove 301 and hooked and fixed to the groove 301.

[0079] In order to facilitate subsequent maintenance, the fixing seat 110 is separated from the groove 301 of the profile. Figure 6 and Figure 7As shown, an adjustment positioning hole 145 is provided on the side of the first clamp block 141 or the second clamp block 142 away from the other side, and the fixing seat 110 is provided with a first adjustment opening 115 corresponding to the adjustment positioning hole 145 for the adjustment tool 400 to pass through and extend into the adjustment positioning hole 145. Based on the above structure, the adjustment tool 400 can be inserted into the adjustment positioning port after being inserted into the first adjustment opening 115, and then force can be applied to compress the elastic member 1431, reduce the distance between the first clamp block 141 and the second clamp block 142, and then separate the first hook 1411 and the second hook from the profile to remove the fixing seat 110. The adjustment positioning hole 145 can prevent the adjustment tool 400 from slipping when force is applied. Here, the adjustment tool 400 can be a slender column, such as a wire, a screwdriver, an Allen wrench, etc.

[0080] The second structure is: Figure 8 and Fig. 9 As shown, the push-off member 143 is a threaded adjustment rod 1432, and the threaded adjustment rod 1432 includes a first threaded connection portion 1433 and a clamping section 1434, wherein the first threaded connection portion 1433 is provided with an external thread, and the clamping section 1434 is provided with an annular clamping groove 1436, and the end surface of the first threaded connection portion is provided with a first tool connection groove 1437 for circumferentially fixed connection with the adjustment tool 400. After the adjustment tool 400 is inserted into the first tool connection groove 1437, the threaded adjustment rod 1432 can be rotationally adjusted. Here, the first tool connection groove 1437 can be a cross shape, a straight shape, or a regular hexagon, etc., and correspondingly, the adjustment tool 400 can be a cross screwdriver, a straight screwdriver, or a hexagonal wrench.

[0081] like Figure 8 As shown, the first clamp block 141 is provided with a threaded hole 1438 matching the external thread, the fixing seat 110 is provided with a second adjustment opening 116 for the adjustment tool 400 to pass through and extend into the threaded hole 1438 at a position corresponding to the threaded hole 1438, and the second clamp block 142 is provided with a clamping groove 1439 on one side close to the first clamp block 141 which can be clamped and fixed with the annular clamping groove 1436.

[0082] The first threaded connection portion 1433 of the threaded adjustment rod 1432 is installed in the threaded hole 1438 , and the annular clamping groove 1436 of the clamping section 1434 is fixedly connected to the clamping groove 1439 .

[0083] Based on the above structure, the first clamp block 141 and the second clamp block 142 are connected by a threaded adjustment rod 1432, and the second clamp block 142 is fixed at the end of the threaded adjustment rod 1432. The first clamp block 141 is threadedly connected to the threaded adjustment rod 1432. When the threaded adjustment rod 1432 rotates, due to the limiting effect of the clamp block accommodating groove 113, the first clamp block 141 and the second clamp block 142 cannot rotate with it, so that the first clamp block 141 will move on the threaded adjustment rod 1432, thereby changing the distance between the first clamp block 141 and the second clamp block 142, so as to achieve the fixation or separation of the first hook 1411, the second hook 1421 and the profile.

[0084] The third structure is a combination of the above two structures, that is, the clamping structure 140 is provided with two groups, one group of push-off members 143 uses an elastic member 1431 , and the other group uses a threaded adjustment rod 1432 .

[0085] Preferably, the fixing seat 110 and the door and window profile in the vertical direction adopt the following structure:

[0086] like Figures 10 to 12 As shown, the actuator 100 of the door and window lock also includes a limiting member 146, which includes a limiting column 1461, a limiting convex edge 1462 fixedly arranged at one end of the limiting column 1461, and a second connecting portion 1463 arranged on one side of the limiting convex edge 1462. The limiting column 1461 is provided with a second tool connecting groove 1464 on the end surface away from the limiting convex edge 1462 for circumferentially fixedly connected with the adjustment tool 400; the fixing seat 110 is provided with a limiting through hole 117 matching the limiting member; the second connecting portion 1463 is connected and fixed to the base 300 with the handle 200, and the limiting convex edge 1462 is against the base 300. The shape of the second tool connecting groove 1464 can be a cross, a straight or a regular hexagon, etc. Correspondingly, the adjustment tool 400 can be a cross screwdriver, a straight screwdriver or a hexagon wrench.

[0087] That is, the limiting member 146 is fixed on the profile and inserted into the limiting through hole 117, so as to realize the upper and lower limiting of the fixing seat 110. Specifically, during installation, the limiting member 146 is inserted into the limiting through hole 117, and then the fixing seat 110 is installed into the groove 301 of the profile and fixed by the clamping structure 140, and then the handle 200 is installed on the outer side of the profile, and the handle 200 is aligned with the limiting member 146. The limiting member 146 is rotated by the adjusting tool 400, so that the handle 200 is threadedly connected and fixed with the limiting member 146, and the limiting convex edge 1462 is against the profile to cooperate with the handle 200 to clamp the profile. In this way, the number of openings on the fixing seat 110 can be reduced, making it more beautiful. In general, the limiting through hole 117 is usually set to 2, plus the shaft through hole 118, a total of 3 holes, the number of holes is small, and it is more beautiful. In the prior art, in addition to the above three holes, at least two screw connection holes are required, that is, at least five holes. The number of holes is too large and not beautiful enough.

[0088] Specifically, the second connection portion 1463 has two structures:

[0089] One of them is: Fig.10 As shown, the second connection portion 1463 is a threaded connection hole, which is arranged on the side of the limiting flange 1462 and extends in the direction of the limiting column 1461. Correspondingly, a protruding stud 202 is provided on the handle 200, and the stud 202 can be connected and fixed with the threaded connection hole.
