[0045] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0046] First embodiment:

[0047] like Figure 1As shown, an adjustable locking point device for doors and windows, according to the first embodiment of this utility model, includes a transmission component 1, an adjusting seat 2, an adjusting component 3, and an adjustable locking point 4. The transmission component 1 is installed on the window sash of the door or window. The adjusting seat 2 is connected to the transmission component 1, and the adjusting seat 2 has a rotating cavity 201 and a movable cavity 202 that are interconnected. The adjusting component 3 and the adjustable locking point 4 are respectively disposed in the rotating cavity 201 and the movable cavity 202, and they cooperate with each other, thereby using the adjusting component 3 to lock or release the adjustable locking point 4. This allows the adjustable locking point 4 to freely adjust its length protruding from the surface of the transmission component 1, thereby precisely controlling the locking position of the adjustable locking point 4 and improving the locking effect of the door or window.

[0048] Specifically, such as Figure 2 As shown, in this embodiment, the transmission component 1 is a rectangular plate structure. A connecting hole 11 is provided on the transmission component 1 to connect it to the adjusting seat 2 via a connecting component 10 (e.g., a bolt), thereby limiting the relative position of the transmission component 1 and the adjusting seat 2. It is understood that in another embodiment, the adjusting seat 2 can also be integrally formed with the transmission component 1.

[0049] like Figure 2 As shown, the side of the adjusting seat 2 facing the transmission component 1 (i.e.) Figure 2 The transmission component 1 (on the left side) has a rotating cavity 201 and a movable cavity 202. The rotating cavity 201 and the movable cavity 202 are adjacent to and communicate with each other. An adjustment hole 12 is provided on the transmission component 1 at a position corresponding to the rotating cavity 201, for engagement with an adjustment component 3 (described in detail below). A movable hole 13 is provided on the transmission component 1 at a position corresponding to the movable cavity 202, for engagement with an adjustable locking point 4 (described in detail below).

[0050] like Figure 1 and Figure 2 As shown, the adjusting member 3 is an eccentric shaft, and a first meshing tooth 31 is provided on the outer side of the eccentric shaft 3. The adjusting member 3 is rotatably accommodated in the rotating cavity 201 about a preset direction (in this embodiment, the X direction perpendicular to the surface of the transmission member 1), and one end of the adjusting member 3 (i.e. Figure 2 The left end of the adjusting member 3 is located within the adjusting hole 12. In this embodiment, the left end of the adjusting member 3 has an adjusting port 31 (e.g., a hexagonal screw thread), which is matched with an adjusting tool (e.g., a hexagonal wrench) to drive the adjusting member 3 to rotate clockwise or counterclockwise, thereby switching the adjusting member 3 between the first state and the second state. Specifically, in this embodiment, as shown... Figure 3 As shown, adjusting member 3 is in the first state; as Figure 4 and Figure 5As shown, the adjusting member 3 is in the second state. When the adjusting tool drives the adjusting member 3 to rotate 90° counterclockwise, the adjusting member 3 switches from the first state to the second state; when the adjusting tool drives the adjusting member 3 to rotate 90° clockwise, the adjusting member 3 switches from the second state to the first state.

[0051] like Figure 1 and Figure 2 As shown, the adjustable locking point 4 is telescopically movable within the movable cavity 202 along a preset direction (i.e., the X direction), and one end of the adjustable locking point 4 protrudes from the movable hole 13. The adjustable locking point 4 cooperates with the adjusting member 3 to switch between a locked state and a released state, thereby allowing adjustment of the length of the adjustable locking point 4 protruding from the movable hole 13 in the released state and maintaining stability in the locked state. Specifically, a second engaging tooth 41 is provided on the side of the adjustable locking point 4 near the adjusting member. When the adjusting member 3 is in the first state, the first engaging tooth 31 and the second engaging tooth 41 engage to lock the adjustable locking point 4; when the adjusting member 3 is in the second state, the first engaging tooth 31 and the second engaging tooth 41 disengage to release the adjustable locking point 4.

[0052] The following is combined Figure 3-5 The working principle of the adjustable locking point device for this door and window is explained below:

[0053] like Figure 3 As shown, the adjusting member 3 is in the first state. At this time, the first meshing tooth 31 and the second meshing tooth 41 mesh together so that the adjustable locking point 4 is in the locked state.

[0054] like Figure 4 As shown, when it is necessary to adjust the adjustable locking point 4, the adjusting tool drives the adjusting part to rotate 90° counterclockwise. At this time, the first meshing tooth 31 and the second meshing tooth 41 are separated, so that the adjustable locking point 4 is in the loose state.

[0055] Then, the position is adjusted by moving the adjustable locking point 4, such as... Figure 5 The image shows the state after the adjustable locking point 4 has been adjusted. At this point, the tool can be rotated 90° clockwise to make the first meshing tooth 31 mesh with the second meshing tooth 41, thereby locking the adjustable locking point 4 again.

[0056] Furthermore, in the above embodiments, such as Figure 2 As shown, preferably, the inner wall of the movable cavity 202 is provided with a first guide portion 210 (a strip-shaped protrusion in this embodiment) along a preset direction, and the outer wall of the adjustable locking point 4 is provided with a second guide portion (a strip-shaped groove in this embodiment, not shown in the figure) along a preset direction. The first guide portion 210 and the second guide portion cooperate to guide the adjustable locking point 4 to move.

[0057] Furthermore, in the above embodiments, such as Figure 2 As shown, preferably, a force-applying part 42 (a flange in this embodiment, but not limited to this structural form) is formed at the end of the adjustable locking point 4 away from the adjusting seat 3, so as to transmit force to the adjustable locking point 4 through the force-applying part 42. It can be understood that the force-applying part 42 can more easily drive the adjustable locking point 4 to move telescopically, thereby improving the convenience of moving the adjustable locking point 4.

[0058] Second embodiment:

[0059] like Figure 6-8 As shown, an adjustable locking point device for doors and windows, provided in the second embodiment of this utility model, includes a transmission component 1, an adjusting base 2, an adjusting component 3, and an adjustable locking point 4. The difference between this embodiment and the first embodiment lies in the different structural forms of the adjusting component 3 and the adjustable locking point 4.

[0060] Specifically, in this embodiment, the adjusting member 3 is an eccentric shaft, and a first engaging portion 33 is provided on the outer side of the eccentric shaft. Correspondingly, a plurality of second engaging portions 43 are provided on the side of the adjustable locking point 4 near the adjusting member 3, and the plurality of second engaging portions 43 are spaced apart along the X direction. Thus, when the adjusting member 3 is in the first state, the first engaging portion 33 engages with any of the second engaging portions 43, so that the adjustable locking point 4 is in a locked state. When the adjusting member 3 is in the second state, the first engaging portion 33 separates from the second engaging portion 43, so that the adjustable locking point is in a released state.

[0061] In specific adjustments Figure 6 The state shown indicates that the adjustable locking point 4 is in the locked state. At this time, the first engaging part 33 is engaged with the upper second engaging part 43. When the adjusting tool drives the adjusting part to rotate counterclockwise by 90°, the first engaging part 33 separates from the upper second engaging part 43 (as shown). Figure 7 As shown in the diagram, at this time, the adjustable locking point 4 can move up and down, thereby aligning the lower second engaging part 43 with the first engaging part 33. Finally, by using the adjusting tool to rotate the adjusting part 90° clockwise, the first engaging part 33 engages with the lower second engaging part 43, thus locking the adjustable locking point 4 again.

[0062] Except for the differences mentioned above, the structure of this embodiment is the same as that of the first embodiment, and will not be described again here.

[0063] Third embodiment:

[0064] like Figure 9-11 As shown, an adjustable locking point device for doors and windows, provided in the third embodiment of this utility model, includes a transmission component 1, an adjusting base 2, an adjusting component 3, and an adjustable locking point 4. The difference between this embodiment and the first embodiment lies in the different structural forms of the adjusting component 3 and the adjustable locking point 4.

[0065] Specifically, in this embodiment, the adjusting member 3 is a notched eccentric shaft with a notched portion 310, and a first engaging portion 33 is provided on the outer wall of the notched eccentric shaft at a position corresponding to the notched portion. The first engaging portion 33 is offset from the rotation center by a certain distance, that is, the engaging portion and the rotation center have a maximum distance and a minimum distance. Correspondingly, a plurality of second engaging portions 43 are provided on the side of the adjustable locking point 4 near the adjusting member 3, and the plurality of second engaging portions 43 are spaced apart along a preset direction.

[0066] Therefore, when the adjusting member 3 is in the first state, the first engaging part 33 engages with any of the second engaging parts 43, so that the adjustable locking point 4 is in a locked state. When the adjusting member 3 is in the second state, the first engaging part 33 and the second engaging part 43 separate, so that the adjustable locking point 4 is in a released state.

[0067] In specific adjustments Figure 9 The state shown indicates that the adjustable locking point 4 is in the locked state. At this time, the first engaging part 33 is engaged with the upper second engaging part 43. When the adjusting tool drives the adjusting part to rotate counterclockwise by 90°, the first engaging part 33 separates from the upper second engaging part 43 (as shown). Figure 10 As shown), at this time, the adjustable locking point 4 can move up and down, thereby aligning the lower second engaging part 43 with the first engaging part 33 (as shown). Figure 11 (As shown). Finally, by using the adjusting tool to rotate the adjusting part 90° clockwise, the first engaging part 33 engages with the second engaging part 43 below, thereby locking the adjustable locking point 4 again.

[0068] Except for the differences mentioned above, the structure of this embodiment is the same as that of the first embodiment, and will not be described again here.

[0069] Fourth embodiment:

[0070] like Figure 12-14 As shown, an adjustable locking point device for doors and windows, provided in the second embodiment of this utility model, includes a transmission component 1, an adjusting base 2, an adjusting component 3, and an adjustable locking point 4. The difference between this embodiment and the first embodiment lies in the different structural forms of the adjusting component 3 and the adjustable locking point 4.

[0071] Specifically, in this embodiment, the adjusting member 3 is a notched shaft with a notched portion 310, and a first engaging portion 33 is provided on the outer wall of the notched shaft at a position corresponding to the notched portion. The first engaging portion 33 has no offset distance from the rotation center; that is, the distance between the engaging portion and the rotation center is always the same. Correspondingly, a plurality of second engaging portions 43 are provided on the side of the adjustable locking point 4 near the adjusting member, and the plurality of second engaging portions 43 are spaced apart along a preset direction. When the adjusting member 3 is in the first state, the first engaging portion 33 engages with any of the second engaging portions 43, so that the adjustable locking point 4 is in a locked state; when the adjusting member is in the second state, the first engaging portion 33 separates from the second engaging portion 43, so that the adjustable locking point 4 is in a released state.

[0072] In specific adjustments Figure 12 The state shown indicates that the adjustable locking point 4 is in the locked state. At this time, the first engaging part 33 is engaged with the upper second engaging part 43. When the adjusting tool drives the adjusting part to rotate counterclockwise by 90°, the first engaging part 33 separates from the upper second engaging part 43 (as shown). Figure 13 As shown), at this time, the adjustable locking point 4 can move up and down, thereby aligning the lower second engaging part 43 with the first engaging part 33 (as shown). Figure 14 (As shown). Finally, by using the adjusting tool to rotate the adjusting part 90° clockwise, the first engaging part 33 engages with the second engaging part 43 below, thereby locking the adjustable locking point 4 again.

[0073] Except for the differences mentioned above, the structure of this embodiment is the same as that of the first embodiment, and will not be described again here.
