Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and in particular to a translational and lateral pressure locking structure. Background Art

[0002] A locking structure of a sliding door and window includes a base and a lock seat. The lock seat is installed on the door and window profile. The base is slidably arranged on the side of the door and window leaf. The base is equipped with a lock hook facing the door and window profile, and the lock seat is equipped with a lock column. After the door and window are closed, the base can be slid to drive the lock hook to hook on the lock column, thereby achieving locking. In order to facilitate the pushing and pulling of the door and window leaf, there is a certain gap between the door and window leaf and the door and window profile, which makes the door and window unable to be closed tightly when closed. Utility Model Content

[0003] The utility model aims to provide a locking structure with translational lateral pressure 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 translational side pressure locking structure, comprising: a lock seat, a accommodating cavity is opened on one side, a lock column is installed in the accommodating cavity, and the accommodating cavity is provided with an inclined surface; a base, a lock hook and a guide column are installed on one side, when the lock hook passes through between the lock column and the bottom wall of the accommodating cavity, the guide column contacts the inclined surface, so that the base and the lock seat can move relative to each other along the axial direction of the lock column.

[0005] The technical solution has at least the following beneficial effects: the lock seat is mounted on the door and window profile, and the base is slidably mounted on the door and window sash. By sliding the base, the lock hook can be driven to pass between the lock column and the bottom wall of the accommodating cavity. The lock hook is restricted by the lock column and cannot be pulled out, so that the door and window sash cannot be pushed open, thereby achieving a locking effect. When the guide column contacts the inclined surface, the lock hook continues to be pushed, and the guiding effect of the inclined surface forces the guide column, the base and the door and window sash to move horizontally together, and the door and window sash is pressed against one side of the door and window profile to achieve a sealing effect.

[0006] As a further improvement of the above technical solution, the guide column comprises a connected mounting section and a guide section, the diameter of the mounting section is smaller than the diameter of the guide section, and the mounting section is riveted to the base, so as to facilitate the assembly of the guide column and the base.

[0007] As a further improvement of the above technical solution, a set screw is threadedly mounted on the base, and one end of the set screw abuts against the mounting section, thereby further stabilizing the position of the mounting section and preventing the mounting section from sliding and rotating relative to the base.

[0008] As a further improvement of the above technical solution, the set screw is arranged at an angle away from the guide section at one end thereof that contacts the installation section. When the set screw presses against the installation section, a tightening force can be applied to the installation section to further embed the installation section at one end of the base, thereby further improving the stability of the installation section and preventing the installation section from loosening.

[0009] As a further improvement of the above technical solution, the axis of the guide section and the axis of the installation section are arranged so as not to overlap. The position of the guide column can be adjusted by rotation, thereby adjusting the sealing degree of the door and window sashes.

[0010] As a further improvement of the above technical solution, the guide section is provided with a convex edge at one end away from the mounting section, and the outer cover of the guide section is provided with a first roller sleeve located between the convex edge and the base. The first roller sleeve is in contact with the inclined surface, so that the friction force of the guide section sliding relative to the inclined surface can be reduced, thereby improving the smoothness of the guiding movement of the guide section.

[0011] As a further improvement of the above technical solution, the lock column is rotatably mounted with a second roller sleeve. When the lock hook contacts the second roller sleeve, the friction between the lock hook and the lock column can be reduced, thereby improving the smoothness of the movement of the lock hook.

[0012] As a further improvement of the above technical solution, the lock cylinder is riveted and fixed to the lock seat, which facilitates the installation of the lock cylinder.

[0013] As a further improvement of the above technical solution, a tightening slope is provided at the end of the lock hook and toward the side of the base. When the door or window sash is not fully closed, the sliding base drives the lock hook to move, and the door or window sash can be pulled fully closed by the guidance of the tightening slope, so that the lock hook can smoothly pass through the gap between the lock column and the bottom wall of the accommodating cavity to achieve locking.

[0014] As a further improvement of the above technical solution, the inclined surface is a curved surface protruding toward the inside of the accommodating cavity, so that the door and window sash can be more stable when pressing one side of the door and window profile.

[0025] Reference Figure 1-4, a locking structure with translational side pressure, comprises a lock seat 100 and a base 200. A receiving chamber 110 is provided on the right side of the lock seat 100, and a lock column 120 is provided on the front and rear side walls of the middle position of the receiving chamber 110 to rotate together. The lock column 120 is a straight rivet and is connected to the lock seat 100 by riveting. A second roller sleeve 122 is sleeved on the lock column 120 at the middle position, and the second roller sleeve 122 can be rotatably arranged relative to the lock column 120, and the outer side wall of the second roller sleeve 122 is at a preset first distance from the bottom wall of the receiving chamber 110. An inclined surface 111 is provided at the top position of the front side wall of the receiving chamber 110, and the inclined surface 111 is an arc surface, which protrudes from the receiving chamber 110 toward the rear side.

[0026] A lock hook 300 is installed at the lower left side of the base 200, and the lock hook 300 can be integrally formed with the base 200. The lock hook 300 is L-shaped as a whole, and the hook tip of the lock hook 300 is arranged upward. The thickness of the lock hook 300 is less than or equal to the first distance. Preferably, the thickness of the lock hook 300 is slightly less than the first distance. A tightening slope 310 is arranged on the right side of the hook tip of the lock hook 300, and the top edge of the tightening slope 310 is inclined toward the left side. A stabilizing notch 320 is arranged at the bottom position of the right side of the lock hook 300.

[0027] A guide post 400 is installed at the upper left side of the base 200. Specifically, the second distance between the top of the lock hook 300 and the bottom of the guide post 400 is slightly smaller than the third distance between the bottom of the inclined surface 111 and the top of the lock post 120. The rearmost position of the inclined surface 111 is later than the guide post 400. Locking screws are penetrated at the top and bottom of the lock base 100, and the lock base 100 is fixedly installed on the inner side of the door and window profile through the locking screws, and the base 200 is slidably installed on the side wall of the door and window leaf, and a locking piece connected to the base 200 is slidably installed on the front side of the door and window leaf. The relative position of the lock base 100 and the base 200 should meet the following requirements: when the base 200 is at the lowest position of the sliding range, the top of the hook tip of the lock hook 300 is lower than the bottom of the lock post 120; when the base 200 is at the highest position of the sliding range, the height position of the stable notch 320 of the lock hook 300 is the same as the height position of the lock post 120. That is, it can be understood that the sliding distance of the base 200 is greater than the fourth distance between the stable notch 320 and the top of the hook tip. After closing the door and window sash, the base 200 can be driven to move upward by pushing the locking member upward. At this time, the lock hook 300 passes through the gap between the lock column 120 and the bottom wall of the accommodating cavity 110, so that the lock column 120 falls into the right range of the stable notch 320. Since the lock hook 300 is hooked on the lock column 120, the door and window sash cannot be opened at this time, thereby achieving the locking effect. By slightly pulling the door and window sash, the lock column 120 can be embedded in the position of the stable notch 320, so that the lock hook 300 is not easy to fall off, thereby improving the stability of the locked state.

[0028] It should be noted that, in the process of the lock hook 300 passing through the gap between the lock column 120 and the bottom wall of the accommodating chamber 110, the guide column 400 abuts against the inclined surface 111. As the guide column 400 continues to move upward, the guide column 400, the base 200 and the door and window sash can be pushed to move backward together, and the rear side of the door and window sash is set to abut against the front side of the door and window profile track to achieve a sealing effect when locking. When the door and window sash is not fully closed, as long as the tightening inclined surface 310 of the lock hook 300 is located below the lock column 120, the tightening inclined surface 310 can be used to abut against the lock column 120 to guide the door and window sash in the process of pushing the base 200, so that the lock hook 300 can smoothly pass through the gap between the lock column 120 and the bottom wall of the accommodating chamber 110 to complete the locking.

[0029] The guide column 400 can be divided into a mounting section 410 with a smaller diameter and a guide section 420 with a larger diameter. The mounting section 410 is fixed vertically and riveted to the upper left side of the base 200. A convex edge 421 is integrally formed at the leftmost end of the guide section 420. A first roller sleeve 422 is sleeved on the outer side of the guide section 420. The first roller sleeve 422 can rotate relative to the guide section 420, and the first roller sleeve 422 is restricted between the right side of the convex edge 421 and the left side of the base 200. This facilitates the installation of the first roller sleeve 422.

[0030] The axis of the guide section 420 is parallel to the axis of the installation section 410. Since the uppermost position of the base 200 corresponds to the position where the guide column 400 stops guiding translation relative to the inclined surface 111, in this state, the door and window sashes need to be pressed against the track side of the door and window sash profile to achieve a sealing effect. Therefore, in order to ensure that the sealing is adjustable, the axis of the guide section 420 deviates from the installation section 410 by a certain distance. When installing the guide column 400, the angle position of the guide section 420 can be adjusted by rotating it according to the required degree of sealing on the door and window. Taking the axis of the guide section 420 being directly above the axis of the mounting section 410 as a reference, when the axis of the guide section 420 is directly in front of the axis of the mounting section 410, during the upward movement of the base 200, the guide section 420 will contact the inclined surface 111 in advance, thereby increasing the travel of the guide section 420 contacting the inclined surface 111, and thus the door and window sash can be moved backwards a greater distance; when the axis of the guide section 420 is directly behind the axis of the mounting section 410, during the upward movement of the base 200, the guide section 420 will contact the inclined surface 111 later, thereby reducing the travel of the guide section 420 contacting the inclined surface 111, and thus the door and window sash can be moved backwards a smaller distance. Therefore, the angular position of the guide column 400 can be adjusted according to the gap between the door and window sash and the door and window profile, thereby ensuring the airtightness of the door and window sash after locking.

[0031] In addition, a set screw 500 is threadedly inserted into the top of the base 200, and a chamfer is provided on the outer periphery of the bottom end of the set screw 500. The bottom end of the set screw 500 penetrates the base 200 and contacts the outer peripheral side wall of the mounting section 410, thereby stabilizing the axial position and axial position of the guide column 400. The bottom end of the set screw 500 is tilted toward the right direction, so that the bottom end of the set screw 500 exerts a right-side force on the mounting section 410 in the process of pressing against the mounting section 410, further fastening the mounting section 410 in the base 200. This ensures that the angular position of the guide column 400 is not easy to change in the process of contacting the inclined surface 111, thereby ensuring the sealing stability of the door and window sash when locked.

[0032] 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.
