Description

Technical Field

[0001] The invention relates to the field of door and window equipment, and in particular to a position-adjustable locking point transmission structure and a door and window. Background Art

[0002] During the installation of doors and windows, when closing the doors and windows, the distance between different door and window frames and the door or window frames may be larger or smaller, which requires adjusting the distance between the lock point and the keyhole seat, that is, the lock point needs to be adjusted forward and backward along the axial direction. In addition, due to site reasons or installation errors, the lock point often cannot be aligned with the keyhole seat, which will result in failure to lock or unlock normally.

[0003] For the sash profile without slots, the general installation form of the lock seat is self-tapping screw installation. After the lock seat is installed on the profile, if the lock point and lock seat are not matched within a short distance, it needs to be reinstalled; if the reinstallation position is very close, the lock seat cannot be installed due to the screw installation diameter problem. In addition, the lock point adjustment of most current lock point transmission structures can only adjust the frame and sash extrusion amount, and if the lock point and lock seat position do not match, it cannot be solved. Summary of the invention

[0004] The present invention provides a locking point transmission structure and a door and window with adjustable position, so as to solve the problem that the locking point and the lock seat cannot be matched due to installation error.

[0054] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0055] An embodiment of the present invention provides a locking point transmission structure with adjustable position. After the doors and windows are installed, the installation position of the locking point can be fine-tuned by adjusting the adjustment member, so that the locking point can perfectly cooperate with the lock seat, thereby solving the problem that the locking point and the lock seat cannot effectively cooperate due to a small distance difference.

[0056] First embodiment:

[0057] like Figure 1-8 As shown, a locking point transmission structure with adjustable position provided by the first embodiment of the present invention includes a static piece 1, a dynamic piece 2, a transmission member 3, a locking point 4 and an adjusting member 5. The static piece 1 and the dynamic piece 2 can move relatively, and the locking point 4 and the adjusting member 5 are respectively connected to the two ends of the transmission member 3, and are respectively connected to the static piece 1 and the dynamic piece 2 to jointly realize the transmission connection between the static piece 1 and the dynamic piece 2, so that the locking point 4 is driven to move along the length direction of the static piece 1 through the adjusting member 5 to adjust the installation position of the locking point 4.

[0058] Specifically, Figure 2 As shown, the static sheet 1 is a strip plate installed on the fan profile. Figure 2 The surface of the static piece 1 is provided with a sliding groove 11 (in the X direction), and a rotating hole 12 is provided on the surface of the static piece 1. The sliding groove 11 is used for sliding cooperation with the locking point 4, and the rotating hole 12 is used for rotating cooperation with the adjusting member 5. In addition, both ends of the static piece 1 are provided with mounting holes 13, so that the static piece 1 can be mounted on the fan profile through a connecting member (for example, a bolt). Correspondingly, the moving piece 2 is connected to one of the mounting holes 13 (in this embodiment, the mounting hole 13 is located at Figure 2 An avoidance groove 201 is provided at a position corresponding to the mounting hole above the connector to avoid the connector.

[0059] like Figure 1 and Figure 2 As shown, the moving piece 2 is a strip plate, which is movably arranged on one side of the static piece 1 (i.e. Figure 1 In addition, a connection hole 21 is provided at a position corresponding to the slide slot 11 on the movable plate 2, and a connection slot 22 is provided at a position corresponding to the rotation hole 12. The connection hole 21 is used to connect with the locking point 4, and the connection slot 22 is used to slide with the adjusting member 5.

[0060] like Figure 1 and Figure 2 As shown, the transmission member 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 adjustment member 5.

[0061] like Figure 3 and Figure 4As shown, the locking point 4 is inserted into the slide groove 11 and the connecting hole 21, and is connected to the locking point hole 301 of the transmission member 3. Thus, the static plate 1, the moving plate 2 and the transmission member 3 are connected through the locking point 4, and the locking point 4 can slide in the slide groove 11. Preferably, the locking point 4 is an eccentric structure, so that when the locking point 4 matches the installation position of the lock seat, the locking point 4 can be rotated eccentrically to adjust the extrusion amount 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, and the top end of the adjusting member 5 passes through the rotating hole 12, and the bottom end of the adjusting member 5 passes through the connecting groove 22 and is connected to the offset hole 302 of the transmission member 3. In this embodiment, preferably, the adjusting member 5 is an offset shaft, and the offset shaft is an eccentric structure. Therefore, when the adjusting member 5 is rotated, the transmission member 3 can be driven to reciprocate in the XY plane through the eccentric cooperation between the adjusting member 5 and the offset hole 302, and then through the cooperation between the locking point hole 301 and the locking point 4, the locking point 4 is reciprocated 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 scales around it, and the adjusting member 5 is provided with an indicating portion 51 , which points to the scales to indicate the adjustment amount of the locking point 4 through the scales.

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

[0065] like Figure 6 As shown, position 1 is when the locking point 4 is in the original position.

[0066] When the locking point 4 needs to be adjusted to the left (if it is installed vertically, it is adjusted downward), the adjusting member 5 is rotated counterclockwise by a wrench. At this time, the eccentric cooperation between the adjusting member 5 and the offset hole 302 drives the transmission member 3 to move to the left; accordingly, the cooperation between the locking point hole 301 and the locking point 4 causes the locking point 4 to move to the left along the slide groove 11, so that the locking point 4 moves to the left by a certain distance (for example: 1.5mm). That is: adjusting from position one to position two.

[0067] When the locking point 4 needs to be adjusted to the right (upward if installed vertically), the adjusting member 5 is rotated clockwise by a wrench. At this time, the eccentric cooperation between the adjusting member 5 and the offset hole 302 drives the transmission member 3 to move to the right; accordingly, the cooperation between the locking point hole 301 and the locking point 4 causes the locking point 4 to move to the right along the slide groove 11, so that the locking point 4 moves to the right by a certain distance (for example: 1.5mm). That is, it is adjusted from position one to position three.

[0068] In summary, the locking point transmission structure provided by the first embodiment of the present invention can achieve the following effects: the static plate 1 and the dynamic plate 2 move relative to each other, and the locking point 4 can slide in the slide groove 11 by rotating the adjusting member 5. Therefore, the adjusting member 5 can be freely rotated as needed, so that the installation position of the locking point 4 can be adjusted so that the locking point 4 can perfectly match the lock seat. In addition, after the lock point and the lock seat are adjusted, the locking point 4 can be rotated to change the amount of extrusion between the frame and the sash by using the eccentric structure of the locking point 4 itself, thereby improving the stability of the installation.

[0069] Second embodiment:

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

[0071] Specifically, Figure 7 As shown, in this embodiment, the transmission member 3 includes a first slider 31, a second slider 32 and a connecting rod assembly. The first slider 31 is arranged on the side of the moving plate 2 away from the static plate 1 (i.e. Figure 7 The second slider 32 is disposed on the side of the moving piece 2 away from the static piece 1 to be connected to 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 connecting rod assembly includes two curved connecting rods 33, a fulcrum 34, a central rotating shaft 35 and two end rotating shafts 36. Figure 8 As shown, both ends of the curved link 33 are provided with strip grooves 331, and a notch 332 is provided at the bend of the curved link 33. The fulcrum 34 is movably connected to the movable plate 2, and an axis groove 341 is provided at a position corresponding to the notch 332 on the fulcrum 34. The central rotating shaft 35 is penetrated in the axis groove 341 and the notch 332 to connect the fulcrum 34 and the curved link 33. Correspondingly, two end rotating shafts 36 are respectively penetrated in the strip grooves 331 at both ends of the curved link 33, and are respectively connected to the first slider 31 and the second slider 32.

[0073] Reference Fig. 9 and 10 As shown, the locking point 4 is arranged in the slide groove 11 and the connecting hole 21, and is connected to the second slider 32. Thus, the static plate 1, the moving plate 2 and the transmission member 3 are connected through the locking point 4, and the locking point 4 can slide in the slide groove 11. Fig.10As shown, the second sliding block 32 will cooperate with the inner wall of the profile 10 , so that it cannot rotate due to the constraint of the inner wall of the profile groove and can only move along the length direction of the static piece 1 .

[0074] Reference Fig. 9 and Fig.11 As shown, the adjusting member 5 is rotatably installed 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. Fig.11 As shown, the first sliding block 31 will cooperate with the inner wall of the profile 10, so that it cannot rotate due to the constraint of the inner wall of the profile groove and can only move in a direction perpendicular to the surface of the static piece 1.

[0075] In this embodiment, the adjusting member 5 is a screw, which cooperates with the thread of the first slider 31 to drive the first slider 31 to reciprocate in a direction perpendicular to the surface of the static piece 1, and then drives the second slider 32 to reciprocate along the length direction of the static piece 1 through the bent connecting rod 33, thereby driving the locking point 4 to reciprocate along the slide groove 11 through the movable piece 2 to adjust the installation position of the locking point 4.

[0076] It should be understood that in this embodiment, the entire motion chain from the bolt 5 to the locking point 4 can only move in a predetermined operating mode, so that the locking point position can be infinitely adjusted according to demand. Moreover, compared with the first embodiment, this adjustment method has strong impact resistance, and the locking point 4 does not move after long-term use.

[0077] Except for the above differences, the rest of the structure of this embodiment is the same as that of the first embodiment and will not be described again.

[0078] Third embodiment:

[0079] On the basis of the first embodiment or the second embodiment described above, the third embodiment of the present invention further provides a door and window, which includes any one of the above locking point transmission structures.
