Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and in particular to a door and window center column locking structure and the door and window. Background Art

[0002] In order to achieve the fixation between the door leaf or window leaf and the frame, sliding doors and windows usually use a locking point assembly and a lock seat to lock. For example, the locking point assembly is fixed on the door leaf, and the lock seat is fixed on the frame. When the door leaf is closed, the locking point structure of the locking point assembly can slide into the lock seat to lock. In the related art, since there is a certain installation error between the locking point assembly and the lock seat, the lock seat adopts a slidable installation structure so that the lock seat can move to adjust the position, thereby solving the installation error problem between the locking point assembly and the lock seat. However, the overall structure of the lock seat is relatively complex and the overall appearance is not beautiful. Utility Model Content

[0003] The utility model aims to provide a door and window center column locking structure and a door and window, so as to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above technical problems is: a door and window center column locking structure, including: a base, equipped with a lock hook, the lock hook is provided with a first lock edge; a lock frame, equipped with a second lock edge buckled with the first lock edge, the second lock edge is longer than the first lock edge.

[0005] This technical solution has at least the following beneficial effects: the base can be installed on the door and window sashes, and the lock frame can be installed on the center column frame; when the door and window sashes move relative to the center column frame, the first lock edge of the lock hook is buckled with the second lock edge of the lock frame to achieve fixation between the door and window sashes and the center column frame; since the second lock edge is longer than the first lock edge, installation errors in the length direction of the base and the lock hook can be allowed during installation without the need to set up a sliding installation structure; the structure is simple, easy to install and manufacture, and the overall appearance is more simple and beautiful.

[0006] As a further improvement of the above technical solution, a middle column frame is also included, and the lock frame and the middle column frame are integrally formed. This can reduce the trouble of installing the lock frame. At the same time, it can also improve the connection strength between the lock frame and the middle column frame to ensure the stability of the lock frame. In addition, the setting of the parts for installing the lock frame is reduced, and the appearance of the lock frame is more concise and beautiful.

[0007] As a further improvement of the above technical solution, the length of the lock frame and the length of the second lock edge are the same as the length of the center column frame. The length of the lock frame and the second lock edge is set to be the same as the center column frame, and the base can be installed at any position on the length of the door and window sash according to needs, which is convenient for customized installation. At the same time, the lock frame and the second lock edge are not protruding outside the center column frame in the length direction, making the overall structure more concise and beautiful. In addition, the connection between the lock frame and the center column frame is more stable, providing a stable buckle receiving force point for the lock hook, so as to better ensure the stability of the connection between the door and window sash and the center column frame.

[0008] As a further improvement of the above technical solution, the positions where the first locking edge and the second locking edge are buckled are both provided with guiding inclined surfaces. When the door and window sash and the center column frame move relative to each other, even if there is a certain error in the installation positions of the first locking edge and the second locking edge, and the first locking edge and the second locking edge are not at the corresponding buckled positions, the guiding inclined surfaces of the first locking edge and the second locking edge are in conflict, so that the first locking edge and the second locking edge can be guided to the mutually buckled position, thereby ensuring that the first locking edge and the second locking edge can be buckled.

[0009] As a further improvement of the above technical solution, a threaded rod is installed on one side of the lock hook, the threaded rod is threadedly installed on the base, and a fastener for fixing the threaded rod is installed on the base. By rotating the threaded rod one circle, the position of the lock hook relative to the base can be adjusted, so that the distance between the first locking edge and the second locking edge can be adjusted. During installation, the position of the lock hook can be adjusted according to the actual installation position. After installation, it is ensured that the first locking edge of the lock hook and the second locking edge can be buckled normally and firmly, thereby ensuring a firm connection between the door and window sash and the center column frame.

[0010] As a further improvement of the above technical solution, both sides of the lock hook are provided with a first locking edge or both sides of the lock hook are provided with a first locking edge. When adjusting the position of the lock hook relative to the base, the threaded rod can be rotated half a circle or a quarter of a circle to make the first locking edge on the other side of the lock hook buckle with the second locking edge, thereby improving the accuracy of adjusting the position of the lock hook and better ensuring the tightness of the buckling of the first locking edge with the second locking edge.

[0011] As a further improvement of the above technical solution, the threaded rod is rotatably connected to the lock hook, a damping member is installed between the threaded rod and the lock hook, and the damping member abuts against the threaded rod and the lock hook respectively. The lock hook can be adjusted to the most suitable position by rotating the threaded rod at any angle, thereby improving the accuracy of adjusting the position of the lock hook and further ensuring the tightness of the buckling of the first lock edge with the second lock edge; after adjusting the position of the threaded rod, the position of the threaded rod is fixed by a fastener, and then a larger force is applied to rotate the lock hook, so that the first lock edge is in a direction position that can be buckled with the second lock edge, and the damping member can provide a damping effect for the rotation of the lock hook relative to the threaded rod, so that the first lock edge can be maintained in a correct direction position for buckling, thereby ensuring the smooth buckling of the first lock edge with the second lock edge.

[0012] As a further improvement of the above technical solution, the damping member is a rubber ring, which is sleeved on the threaded rod, and the outer circumference and inner circumference of the rubber ring are respectively in contact with the lock hook and the threaded rod. The rubber ring has good elasticity and friction resistance, which can increase the rotational friction between the lock hook and the threaded rod, and can ensure the relative fixation between the lock hook and the threaded rod in a non-stress state or a small stress state.

[0013] As a further improvement of the above technical solution, the threaded rod is rotatably connected to the lock hook, the lock hook is equipped with a guide column, and the base is provided with a guide groove for the guide column to be embedded in. When the threaded rod is rotated, the lock hook cannot rotate under the guidance of the guide column, thereby ensuring that the first locking edge can be stabilized in the correct buckling position, thereby ensuring the smooth buckling of the first locking edge with the second locking edge.

[0014] A door and window comprises the door and window center column locking structure described above, wherein the base and the lock frame are respectively fixed on two profiles in the door and window that can move relative to each other. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Reference Figure 1-3 A locking structure for a door and window center column includes a base 10 and a lock frame 30. A threaded rod 61 is threadedly installed on one side of the base 10. A lock hook 11 is installed on the end of the threaded rod 61 away from the base 10. The lock hook 11 is in the shape of a square plate. The axis of the threaded rod 61 is perpendicular to the plate surface of the lock hook 11. The base 10 is also installed with a fastener 62. The fastener 62 is used to limit the rotation of the threaded rod 61 relative to the base 10, so as to fix the threaded rod 61. A first locking edge 20 is integrally formed on one side of the lock hook 11. One side of the first locking edge 20 protrudes from the outer surface of the lock hook 11 in the direction close to the base 10. A second locking edge 40 is installed on one side of the lock frame 30. The first locking edge 20 and the second locking edge 40 can be buckled together after approaching and crossing each other. Among them, the length of the second locking edge 40 is longer than that of the first locking edge 20. The first locking edge 20 and the second locking edge 40 are both provided with a guide inclined surface 50 on one side of the position where they are close to each other and buckled, so as to ensure the buckling of the first locking edge 20 and the second locking edge 40.

[0030] A door and window, comprising a door and window leaf 90, a center column frame 60 and the door and window center column locking structure described above, wherein a base 10 is mounted on the frame of the door and window leaf 90 by bolts, a lock hook 11 is mounted on one side of the center column frame 60, and the frame of the door and window leaf 90 and the center column frame 60 are two profiles in the door and window that can move relative to each other. Figure 4-5 When the door and window sash 90 moves relative to the center column frame 60, the first locking edge 20 and the second locking edge 40 approach each other and contact each other, and under the action of the guide inclined surface 50, the first locking edge 20 and the second locking edge 40 are smoothly buckled and connected together, so as to relatively and fixedly connect the door and window sash 90 and the center column frame 60. Since the second locking edge 40 is longer than the first locking edge 20, when installing the base 10 and the lock frame 30, even if there is a certain installation error in the length direction, the first locking edge 20 is still within the length range of the second locking edge 40 and is buckled with the second locking edge 40, so that the first locking edge 20 and the second locking edge 40 can be firmly connected.

[0031] Reference Figure 1-3, the lock frame 30 can be integrally formed with the middle column frame 60, and the lock frame 30 and the second lock edge 40 are extended to the same or almost the same length as the middle column frame 60 at both ends in the length direction. The lock frame 30 and the middle column frame 60 are beautiful and not abrupt as a whole, and the connection strength between the lock frame 30 and the middle column frame 60 can be better guaranteed. And the base 10 can be installed at any position in the length direction of the door and window sash 90, which improves the overall adaptability and facilitates customized installation. In the prior art, in order to install the lock seat and provide a connection position for the lock seat to be stressed, the position of the middle column frame 60 corresponding to the lock seat installation often requires special treatment or the addition of ribs and other structures to improve the connection strength of the position, which will increase a certain manufacturing cost. However, if the lock frame 30 and the middle column frame 60 of this embodiment are integrally formed, although the amount of material is increased, the middle column frame as a whole does not need special treatment or additional ribs and other structures, and the manufacturing cost will not increase or can even decrease, thereby ensuring better economy.

[0032] The fastener 62 may be a set screw, which is screwed into the base and abuts against the outer wall of the threaded rod 61, so that the threaded rod 61 cannot rotate relative to the base 10, so as to stabilize the position of the lock hook 11. During installation, the base 10 is first installed in the door and window sash 90, and a circular hole for the threaded rod 61 to pass through is pre-opened on the side of the door and window sash 90 close to the center column frame 60, and the end of the threaded rod 61 away from the lock hook 11 passes through the circular hole from the outside and is screwed into the base 10. The threaded rod 61 can be screwed into the base 10 according to the estimated depth, and then the threaded rod 61 is rotated according to the position of the lock frame 30 or the second lock edge 40 to adjust the position of the first lock edge 20 relative to the second lock edge 40, and the position of the lock hook 11 is adjusted to a position where the first lock edge 20 can be firmly buckled with the second lock edge 40, and then the set screw is screwed in and abuts against the threaded rod 61 to stabilize the position of the lock hook 11 relative to the base 10. It should be noted that in order to ensure that the first locking edge 20 and the second locking edge 40 can be normally buckled in the correct direction, when rotating the threaded rod 61 to adjust the direction of the locking hook 11, the threaded rod 61 needs to be rotated a full circle for adjustment.

[0033] In order to improve the accuracy of the position adjustment of the lock hook 11, the first locking edges 20 can be provided on both sides of the lock hook 11, and the first locking edges 20 on both sides are symmetrically arranged with respect to the rotation center of the lock hook 11. After the threaded rod 61 rotates half a circle, the first locking edge 20 on the other side is in a direction position capable of being buckled with the second locking edge 40, so as to ensure the buckling of the first locking edge 20 and the second locking edge 40. In other embodiments, the first locking edges 20 can be provided on all four sides of the lock hook 11, and the threaded rod 61 can make the first locking edges 20 on the adjacent sides buckle with the second locking edge 40 after rotating a quarter of a circle. In other embodiments, if the lock hook 11 is configured as a triangular, pentagonal or other polygonal plate-shaped structure, the first locking edges 20 can be provided on the corresponding three or five sides, and after the threaded rod 61 is rotated by a corresponding angle, the first locking edge 20 on one side can be buckled with the second locking edge 40.

[0034] Reference Figure 6-7 In other embodiments, the threaded rod 61 and the lock hook 11 can be set to be rotatably connected, and a guide column 80 is installed on the side of the lock hook 11 close to the threaded rod 61. The length direction of the guide column 80 is parallel to the length direction of the threaded rod 61. A guide groove is opened at the position of the base 10 corresponding to the guide column 80, and the guide groove can be used for the guide column 80 to be embedded and slid. When the threaded rod 61 is screwed into the base 10, the guide column 80 is embedded in the guide groove and slides in the guide groove, so that the lock hook 11 can be restricted. When the threaded rod 61 is rotated to any angle, the lock hook 11 does not rotate with the threaded rod 61 and can keep the first locking edge 20 in the direction and position of correct buckling with the second locking edge 40.

[0035] The guide post 80 can be installed at a position parallel to the threaded rod 61, and the guide groove and the threaded hole for the threaded rod 61 to be screwed in are separately opened on the base 10. However, if the installation position of the guide post 80 is set relatively close to or close to the threaded rod 61, the guide groove can be opened on the inner side wall of the threaded hole. In addition, the guide post 80 can also be installed at a position coaxial with the threaded rod 61, the guide post 80 passes through the middle position of the threaded rod 61, and a circular through hole is opened in the middle of the threaded rod 61, so that the threaded rod 61 can rotate relative to the guide post 80, and the guide groove is installed on the bottom wall of the threaded hole. The cross section of the guide post 80 is square or other non-circular, so that the guide post 80 cannot rotate relative to the base 10, but can only slide in the guide groove. When the threaded rod 61 rotates spirally, it can drive the lock hook 11 to move, and the guide post 80 slides in the guide groove within a limited position, so that the lock hook 11 does not rotate with the threaded rod 61, so as to keep the first locking edge 20 stably in the correct buckling position.

[0036] Reference Figure 7In other embodiments, after the threaded rod 61 and the lock hook 11 are set to be rotatably connected, the guide column 80 and the guide groove structure may not be provided, but a damping member is installed between the threaded rod 61 and the lock hook 11, and the two sides of the damping member are respectively pressed against the outer side of the threaded rod 61 and the inner side of the lock hook 11. The damping member plays a role of rotational damping, which can hinder the relative rotation between the threaded rod 61 and the lock hook 11. When the threaded rod 61 is rotated to adjust the position of the lock hook 11, the lock hook 11 will rotate together with the threaded rod 61. After the threaded rod 61 is adjusted to a suitable position, the threaded rod 61 is fixed by the fastener 62, and then the lock hook 11 is rotated by applying a large force to adjust the lock hook 11 to the correct direction position. In daily use, the damping effect of the damping member keeps the first locking edge 20 stably in the correct buckling position, thereby ensuring the normal use of the lock hook 11.

[0037] Specifically, the damping member is a rubber ring 70, which is made of rubber material. The rubber ring 70 is sleeved on the end of the threaded rod 61 away from the base 10, the inner peripheral side of the rubber ring 70 is pressed against the outer wall of the threaded rod 61, and the outer peripheral side of the rubber ring 70 away from the threaded rod 61 is pressed against the lock hook 11. Specifically, a cylindrical structure is provided on the side of the lock hook 11 close to the threaded rod 61, and the cylindrical structure can be embedded and rotatably installed with the threaded rod 61, and the rubber ring 70 is inside the cylindrical structure. It can be understood that the rubber ring 70 has good elasticity and friction resistance, can produce large deformation under the action of external force, and can return to its original state after the external force is removed. When the lock hook 11 rotates relative to the threaded rod 61, the rubber ring 70 can generate large friction resistance to the lock hook 11. Under the action of friction resistance, the lock hook 11 is not easy to rotate relative to the threaded rod 61, and has an excellent rotation damping effect. The rubber ring 70 may be in the shape of a whole ring, a ring with a notch, or an arc.

[0038] In other embodiments, the damping member may also be an elastic plastic member, a spring member, etc. Among them, the elastic plastic member is made of an elastic plastic material, has a certain elasticity, and can provide friction resistance. For example, it can be a thermoplastic elastomer, which is a material with both rubber and plastic properties, showing rubber elasticity at room temperature and a polymer material that can be plasticized and formed at high temperature. The spring member can be a spring sheet or a spring steel wire, both of which can provide friction. For example, the spring sheet is set in the gap between the lock hook 11 and the threaded rod 61, and the spring sheet is deformed by being squeezed, thereby generating friction resistance acting on the lock hook 11, providing a rotation damping effect.

[0039] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
