Description

Technical Field

[0001] This utility model relates to the field of door and window equipment, and in particular to an adjustable locking point transmission structure and a door / window. Background Technology

[0002] During door and window installation, the distance between the door / window frame and the door or window frame varies when the door / window is closed. This necessitates adjusting the distance between the locking point and the lock hole seat, i.e., adjusting the locking point axially. Furthermore, due to site conditions or installation errors, the locking point often fails to align precisely with the lock hole seat, resulting in the inability to lock or unlock properly.

[0003] For slotless fan profiles, the typical installation method for the lock seat is self-tapping screws. If the lock point and lock seat do not align within a short distance after the lock seat is installed, reinstallation is required. If the reinstallation location is very close, the lock seat cannot be installed due to the screw diameter limitation. Furthermore, most current lock point transmission structures can only adjust the frame-fan compression amount when adjusting the lock point; they cannot resolve situations where the lock point and lock seat positions are mismatched. Utility Model Content

[0004] This utility model provides an adjustable locking point transmission structure and door / window to solve the problem that the locking point and locking seat cannot match due to installation errors.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0023] A central pivot is inserted into the shaft groove and the slot to connect the fulcrum and the bending connecting rod;

[0024] The adjusting member is threadedly connected to the first slider, so that rotating the screw drives the first slider to reciprocate in a direction perpendicular to the stationary piece; and the bending connecting rod drives the second slider to reciprocate along the length of the stationary piece to adjust the installation position of the locking point.

[0025] Preferably, there are two bending links, which are symmetrically distributed on both sides of the fulcrum.

[0026] Preferably, the locking point is an eccentric structure, and the locking point can rotate eccentrically to adjust the amount of compression between the locking point and the locking seat.

[0054] 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.

[0055] This utility model provides an adjustable locking point transmission structure. After the door and window are installed, the installation position of the locking point can be finely adjusted by adjusting the adjustment component, so that the locking point can perfectly match the lock seat, thereby solving the problem that the locking point and the lock seat cannot effectively match due to a small distance difference.

[0056] First embodiment:

[0057] like Figure 1-8 As shown, the first embodiment of this utility model provides an adjustable locking point transmission structure, including a stationary plate 1, a moving plate 2, a transmission component 3, a locking point 4, and an adjusting component 5. The stationary plate 1 and the moving plate 2 are movable relative to each other. The locking point 4 and the adjusting component 5 are respectively connected to both ends of the transmission component 3 and to the stationary plate 1 and the moving plate 2, respectively, to jointly realize the transmission connection between the stationary plate 1 and the moving plate 2. Thus, the adjusting component 5 drives the locking point 4 to move along the length direction of the stationary plate 1 to adjust the installation position of the locking point 4.

[0058] Specifically, such as Figure 2 As shown, the stationary plate 1 is a strip plate, mounted on the fan-shaped profile. Furthermore, along its length direction (i.e.,...) Figure 2 A groove 11 is provided in the X direction of the fixed plate 1, and a rotating hole 12 is also provided on the surface of the fixed plate 1. The groove 11 is used for sliding engagement with the locking point 4, and the rotating hole 12 is used for rotating engagement with the adjusting member 5. Furthermore, mounting holes 13 are provided at both ends of the fixed plate 1 to mount the fixed plate 1 onto the fan profile using a connecting member (e.g., bolts). Correspondingly, the moving plate 2 has a mounting hole 13 located at one of the mounting holes 13 (in this embodiment, it is located at...). Figure 2 A clearance groove 201 is provided at the position corresponding to the mounting hole above, so as to avoid the connector.

[0059] like Figure 1 and Figure 2 As shown, the moving plate 2 is a strip plate, which is movably mounted on one side of the stationary plate 1 (i.e., Figure 1 (Right side of the image). Furthermore, a connecting hole 21 is provided on the moving piece 2 at a position corresponding to the sliding groove 11, and a connecting groove 22 is provided at a position corresponding to the rotating hole 12. The connecting hole 21 is used to connect with the locking point 4, and the connecting groove 22 is used for sliding engagement with the adjusting member 5.

[0060] like Figure 1 and Figure 2 As shown, the transmission component 3 is an offset plate, and the two ends of the offset plate are respectively provided with a locking point hole 301 and an offset hole 302. The locking point hole 301 is used to connect with the locking point 4, and the offset hole 302 is used to connect with the adjusting component 5.

[0061] like Figure 3 and Figure 4As shown, the locking point 4 passes through the slide groove 11 and the connecting hole 21, and connects to the locking point hole 301 of the transmission component 3. Thus, the stationary piece 1, the moving piece 2, and the transmission component 3 are connected by the locking point 4, and the locking point 4 can slide within the slide groove 11. Preferably, the locking point 4 has an eccentric structure, so that when the locking point 4 is matched with the installation position of the lock seat, the locking point 4 can be rotated to allow it to rotate eccentrically, thereby adjusting the amount of pressure between the locking point 4 and the lock seat.

[0062] like Figure 3 and Figure 5 As shown, the adjusting member 5 is rotatably installed in the rotating hole 12, with its top end passing through the rotating hole 12 and its bottom end passing through the connecting groove 22 and connecting to the offset hole 302 of the transmission member 3. In this embodiment, preferably, the adjusting member 5 is an offset shaft with an eccentric structure. Therefore, when the adjusting member 5 is rotated, the eccentric engagement between the adjusting member 5 and the offset hole 302 drives the transmission member 3 to reciprocate in the XY plane. Furthermore, through the engagement between the locking hole 301 and the locking point 4, the locking point 4 reciprocates along the slide groove 11 to adjust the installation position of the locking point 4.

[0063] Furthermore, in the above embodiment, preferably, the rotating hole 12 has a scale around its perimeter, and the adjusting member 5 is provided with an indicator 51 that points to the scale to indicate the adjustment amount of the locking point 4.

[0064] Reference Figure 6 As shown, the specific adjustment process of this locking point transmission structure is as follows:

[0065] like Figure 6 As shown, position one is where lock point 4 is in its original position.

[0066] When locking point 4 needs to be adjusted to the left (or downward if vertically installed), the adjusting component 5 is rotated counterclockwise using a wrench. This causes the transmission component 3 to move to the left through the eccentric engagement of the adjusting component 5 with the offset hole 302. Correspondingly, the engagement of the locking point hole 301 with locking point 4 causes locking point 4 to move to the left along the slide groove 11, moving it a certain distance to the left (e.g., 1.5mm). That is, adjusting from position one to position two.

[0067] When locking point 4 needs to be adjusted to the right (or upward if vertically installed), the adjusting component 5 is rotated clockwise using a wrench. This causes the transmission component 3 to move to the right through the eccentric fit between the adjusting component 5 and the offset hole 302. Correspondingly, the locking point 4 moves to the right along the slide groove 11 through the fit between the locking point hole 301 and the locking point 4, allowing the locking point 4 to move a certain distance to the right (e.g., 1.5mm). That is, from position one to position three.

[0068] In summary, the locking point transmission structure provided in the first embodiment of this utility model achieves the following effects: the stationary plate 1 and the moving plate 2 move relative to each other, and the locking point 4 can slide within the slide groove 11 by rotating the adjusting member 5. Therefore, the adjusting member 5 can be freely rotated as needed to adjust the installation position of the locking point 4, ensuring a perfect fit between the locking point 4 and the lock seat. Furthermore, after adjusting the fit between the locking point and the lock seat, the locking point 4 can be rotated to change the amount of compression between the frame and the sash using its eccentric structure, thereby improving installation stability.

[0069] Second embodiment:

[0070] like Figure 7-11 As shown, this is a second embodiment of the adjustable locking point transmission structure provided by the present invention, including a stationary plate 1, a moving plate 2, a transmission component 3, a locking point 4, and an adjusting component 5. The difference between this embodiment and the first embodiment is that the transmission component 3 and the adjusting component 5 have different structural forms.

[0071] Specifically, such as Figure 7 As shown, in this embodiment, the transmission component 3 includes a first slider 31, a second slider 32, and a connecting rod assembly. The first slider 31 is disposed on the side of the moving plate 2 away from the stationary plate 1 (i.e.,...). Figure 7 The first slider 31 is located on the right side of the moving piece 2, away from the stationary piece 1, for connection with the adjusting member 5. The second slider 32 is located on the side of the moving piece 2 away from the stationary piece 1 for connection with the locking point 4. The connecting rod assembly is connected between the first slider 31 and the second slider 32.

[0072] Specifically, refer to Figure 7 As shown, the linkage assembly includes two bent links 33, a fulcrum 34, a central pivot 35, and two end pivots 36. Figure 8 As shown, both ends of the bent connecting rod 33 have strip grooves 331, and the bent part of the bent connecting rod 33 has a slot 332. The fulcrum 34 is movably connected to the moving plate 2, and the fulcrum 34 has a shaft groove 341 at a position corresponding to the slot 332. The central rotating shaft 35 passes through the shaft groove 341 and the slot 332 to connect the fulcrum 34 and the bent connecting rod 33. Correspondingly, the two end rotating shafts 36 pass through the strip grooves 331 at both ends of the bent connecting rod 33, and are respectively connected to the first slider 31 and the second slider 32.

[0073] Reference Figure 9 and 10 As shown, the locking point 4 passes through the slide groove 11 and the connecting hole 21, and is connected to the second slider 32. Thus, the stationary plate 1, the moving plate 2, and the transmission component 3 are connected via the locking point 4, and the locking point 4 can slide within the slide groove 11. Furthermore, referring to… Figure 10As shown, the second slider 32 will cooperate with the inner wall of the profile 10, and thus be constrained by the inner wall of the profile groove and cannot rotate, but can only move along the length direction of the stationary piece 1.

[0074] Reference Figure 9 and Figure 11 As shown, the adjusting member 5 is rotatably mounted in the rotating hole 12, and one end of the adjusting member 5 (the bottom end of the adjusting member 5 in this embodiment) passes through the connecting groove 22 and is connected to the first slider 31. Furthermore, referring to... Figure 11 As shown, the first slider 31 will cooperate with the inner wall of the profile 10, and thus be constrained by the inner wall of the profile groove and cannot rotate, but can only move in a direction perpendicular to the surface of the stationary piece 1.

[0075] In this embodiment, the adjusting component 5 is a screw. Through the screw's thread engagement with the first slider 31, the first slider 31 can be driven to reciprocate along a direction perpendicular to the surface of the stationary plate 1. Then, through the bending connecting rod 33, the second slider 32 is driven to reciprocate along the length direction of the stationary plate 1. Thus, through the moving plate 2, the locking point 4 is driven to reciprocate along the slide groove 11 to adjust the installation position of the locking point 4.

[0076] It should be understood that in this embodiment, the entire motion chain from bolt 5 to locking point 4 can only move according to a predetermined operating pattern, thus allowing for stepless adjustment of the locking point position as needed. Furthermore, compared to the first embodiment, this adjustment method offers stronger impact resistance, and locking point 4 remains stable even after prolonged use.

[0077] 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.

[0078] Third embodiment:

[0079] Based on the first or second embodiment described above, the third embodiment of this utility model also provides a door or window, which includes any of the locking point transmission structures described above.
