Description

Technical Field

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

[0002] The lock body drive structure of doors and windows needs to be fixed on the side of the door and window frame by bolts. Before installing the bolts to fix the lock body drive structure, the lock body drive structure needs to be held all the time to keep the lock body drive structure in the corresponding installation position so that the bolts can be accurately installed to fix the lock body drive structure. The operation process is relatively cumbersome and not conducive to improving installation efficiency. Utility Model Content

[0003] The utility model aims to provide a door and window locking structure and a door and window thereof, 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 as follows: a door and window locking structure includes a shell with a positioning block installed on one side; an elastic member installed on the side of the shell away from the positioning block, and the elastic member provides an elastic force for the shell toward the positioning block.

[0005] This technical solution has at least the following beneficial effects: when the shell is embedded in the groove of the door and window frame, the shell is initially positioned through the positioning action of the positioning block and the door and window frame, and under the elastic force of the elastic member, the shell is abutted against the inner side wall of the groove of the door and window frame to initially fix the shell, thereby reducing the trouble of manually holding the shell to maintain the installation position, facilitating the installation of the shell at the corresponding position of the door and window frame, and improving the installation efficiency of the door and window locking structure.

[0006] As a further improvement of the above technical solution, the elastic member is a spring sheet installed on the side of the housing away from the positioning block, and the two ends of the spring sheet are bent toward the side away from the housing. When the spring sheet presses against the inner side wall of the groove of the door and window frame, it can provide a stable elastic force for the housing, so that the housing can be stably pressed against the other side wall of the groove of the door and window frame, so as to facilitate the preliminary fixing of the housing, and the spring sheet can be easily embedded in the groove of the door and window frame for installation, so as to facilitate the embedded installation of the housing.

[0007] As a further improvement of the above technical solution, the end of the spring sheet is bent toward the side away from the shell and then toward the side close to the shell. The bent portion of the spring sheet end contacts the inner side wall of the groove of the door and window frame, so that the deformation of the spring sheet end is more stable, and the spring sheet can provide a more stable elastic force to the shell.

[0008] As a further improvement of the above technical solution, the spring sheet is fixed to the shell by riveting, so that the connection between the spring sheet and the shell is more stable and reliable, and the elastic force generated by the deformation of the spring sheet can be more stably transmitted to the shell, so that the shell is stably pressed against the inner wall of the door and window frame, so as to further fix and install the shell.

[0009] As a further improvement of the above technical solution, the housing is also equipped with a driving member, which includes a rotating part, a connecting part and a driving part. The rotating part is connected to the driving part through the connecting part. The housing and the spring sheet are both provided with limiting holes. Both ends of the rotating part are provided with limiting blocks that are rotatably connected to the side walls corresponding to the limiting holes. The handle is connected to the rotating part, and the driving part is connected to the shift fork. When the handle rotates, the rotating part can be driven to rotate, and the driving part can be driven to swing under the transmission of the connecting part, thereby driving the shift fork to move up and down to achieve the locking and unlocking of the door and window. The rotating part is assembled between the housing and the spring sheet, and then the spring sheet is fixed to the housing, which can facilitate the installation of the rotating part, reduce the difficulty of production, reduce the production cost, and improve the economy. Through the positioning effect of the limiting hole and the limiting block, the rotating part can be quickly installed between the spring sheet and the housing, which improves the assembly efficiency. At the same time, it can ensure the installation position of the rotating part and improve the accuracy of the assembly of the rotating part.

[0010] As a further improvement of the above technical solution, the positioning block is a circular ring arranged concentrically with the limiting hole. Since the door and window frames generally need to have mounting holes for connecting the handle and the rotating part, the circular ring can be directly adapted and positioned with the mounting holes of the door and window frames, which can reduce the need to open additional holes or slots in the door and window frames to adapt to the positioning block, thereby simplifying the processing of the door and window frames and making it easier to adapt to door and window frames of different styles.

[0011] As a further improvement of the above technical solution, the spring sheet is provided with a groove for the drive unit to be inserted and positioned. The position of the drive unit is limited by the groove provided by the spring sheet, which can ensure that the drive unit is in the corresponding state position of the door and window unlocking and locking at both ends of the movable range.

[0012] As a further improvement of the above technical solution, the housing is provided with a limiting portion, and when the connecting portion is at the end position of the rotation range, the connecting portion abuts against the limiting portion. The abutment of the limiting portion on the connecting portion can limit the rotation range of the connecting portion, thereby limiting the swing range of the driving portion, further ensuring that the driving portion is at the positions at both ends of the activity range corresponding to the state of unlocking and locking the door and window; moreover, the position of the driving portion corresponding to the two states is more stable and reliable.

[0013] As a further improvement of the above technical solution, the driving part is cylindrical. The cylindrical driving part can better fit the side wall of the driving groove of the fork during the up and down swinging process, thereby ensuring the stable connection between the driving part and the fork.

[0014] A door and window comprises the door and window locking structure described above, and also comprises a door and window frame, wherein the door and window frame is provided with a positioning hole adapted to the positioning block. The door and window locking structure is embedded and installed in a groove of the door and window frame, so that the positioning block is adapted to fit in the positioning hole, and the installation position of the shell is preliminarily positioned by the elastic force of the elastic member, so as to facilitate further installation and fixation of the shell, so as to facilitate the fixed installation of the door and window locking structure.

[0025] Reference Figure 1-3 A door and window locking structure includes a shell 10, a driving member 20 and an elastic member. The shell 10 is in a rectangular shape, and a positioning block is installed on one side of the shell 10. A receiving groove is opened on one side of the shell 10, and the driving member 20 is installed in the receiving groove of the shell 10. The driving member 20 can cooperate with the locking members of the doors and windows such as the shift fork, the lock seat and the lock point to realize the locking and unlocking of the doors and windows. The elastic member is installed on the side of the shell 10 away from the positioning block. The elastic force generated by the elastic member can provide the shell 10 with a pressing force against the inner side wall of the groove of the door and window frame, so that the positioning block and the inner side wall of the groove of the door and window frame are positioned and pre-installed, thereby reducing the need to manually hold the shell 10 to keep the shell 10 at the installation position and to accurately install the shell 10, which can facilitate the further fixing and installation of the shell 10 and improve the installation efficiency of the door and window locking structure.

[0026] The elastic member is a spring sheet 30, the width of which is the same as that of the housing 10, and the length of which is longer than that of the housing 10, so that the two ends of the spring sheet 30 protrude from the corresponding two ends of the housing 10. The two ends of the spring sheet 30 are respectively bent at an angle less than 90 degrees toward the end away from the housing 10, and then bent at an angle less than 120 degrees toward the direction close to the housing 10, so that the outer angle side of the second bending of the end of the spring sheet 30 can press against the inner side wall of the groove of the door and window frame. Compared with the scheme in which the spring sheet 30 is bent only once and the end directly presses against the inner side wall of the groove of the door and window frame, this scheme has the advantage that the relative sliding between the spring sheet 30 and the inner side wall of the groove of the door and window frame is not easy to get stuck, so that the deformation of the spring sheet 30 is more stable in the process of pressing against the inner side wall of the groove of the door and window frame, and the direction and magnitude of the elastic force generated can also be more stable and reliable.

[0027] In other embodiments, the elastic member may also be a spring, one end of which is installed on the side of the shell 10 away from the positioning block, and the other end is pressed against the inner side wall of the groove of the door and window frame, so that the spring can provide elastic force for the shell 10 to press against the other side wall of the groove of the door and window frame.

[0028] The spring piece 30 and the shell 10 are fixedly connected by a riveting process, and a plurality of riveting connection points between the spring piece 30 and the shell 10 can be set, thereby suppressing the elastic deformation of the middle part of the spring piece 30 and reducing the situation in which the tightness of the connection between the spring piece 30 and the shell 10 is affected by the pressing force on both sides of the spring piece 30.

[0029] The driving member 20 includes a rotating part 21, a connecting part 22 and a driving part 23. The spring piece 30 is provided with a limiting hole 40 at a position corresponding to the installation position of the rotating part 21. The housing 10 is also provided with a limiting hole 40 at the side wall of the accommodating groove and at a position corresponding to the installation position of the rotating part 21. Limiting blocks 41 are provided at both ends of the rotating part 21. The limiting blocks 41 on both sides are respectively rotatably installed in the corresponding limiting holes 40. The limiting holes 40 are circular holes. The two ends of the driving part 23 can first connect the spring piece 30 and the housing 10 respectively, and then the spring piece 30 and the housing 10 are fixed by riveting. The limiting blocks 41 and the limiting holes 40 not only play the role of positioning and installation, but also play the role of rotational connection. The structural design is ingenious and convenient for overall assembly.

[0030] The connecting portion 22 is used to connect the rotating portion 21 and the driving portion 23. The driving portion 23 is cylindrical and protrudes from the surface of the housing 10. The axis of the driving portion 23 is parallel to the rotation axis of the rotating portion 21, so that the driving portion 23 can be better connected with the lock of the door and window, that is, the fork. When the rotating portion 21 rotates, the driving portion 23 is driven to swing, thereby driving the fork to move up and down, thereby achieving the locking and unlocking of the door and window.

[0031] The spring piece 30 is provided with two grooves 31 on one side close to the driving part 23. When the driving part 23 is in the end state of the two rotation ranges, the driving part 23 can be respectively embedded in the grooves 31 on the corresponding sides. The side walls of the grooves 31 can limit the continued rotation of the driving part 23, so that the driving part 23 is not easy to be separated from the connection structure of the door and window lock, that is, the fork, and the driving connection relationship between the fork and the driving part 23 is maintained. In addition, the driving part 23 is located between the fork and the side walls of the groove, so that the position of the driving part 23 is more stable, and it is not easy to be disengaged due to external forces, so that the connection between the fork and the driving part 23 is more reliable.

[0032] In order to further limit the rotation range of the driving part 23, limiting parts 24 are provided on both side walls of the accommodating groove of the shell 10. When the driving part 23 is in the two end states of the rotation range, that is, when the connecting part 22 is in the two end states of the rotation range, the corresponding limiting parts 24 abut against the side wall of the corresponding side of the connecting part 22. The limiting parts 24 are used to limit the rotation range of the connecting part 22, and then the rotation range of the driving part 23 is limited, thereby ensuring the stability and reliability of the driving member 20 when it is in the end state of the rotation range.

[0033] A circular ring 11 is arranged near the limiting hole 40 of the housing 10, and the circular ring 11 is arranged concentrically with the limiting hole 40, and the circular ring 11 is located at the outer edge of the limiting hole 40. A mounting hole for connecting the handle and the rotating part 21 is provided on the inner side wall of the groove of the door and window frame, and the mounting part of the handle will pass through the mounting hole and the limiting hole 40 to connect with the rotating part 21. At this time, the circular ring 11 can be embedded in the mounting hole for adaptive positioning, and the housing 10 is positioned and installed, thereby reducing the need to set a structure that cooperates with the positioning block on the door and window frame, simplifying the processing of the door and window frame, and improving the adaptability of the door and window locking structure.

[0034] Reference Figure 4 The present embodiment also provides a door and window, including any one of the door and window locking structures described above, and also including a door and window frame 50, the housing 10 is installed in the inner side wall of the groove of the door and window frame 50, and a positioning hole 51 is opened in the inner side wall of the groove of the door and window frame 50, and the positioning hole 51 is the mounting hole mentioned above. The positioning hole 51 is adapted to fit and position with the positioning block. When installing the housing 10, one side of the housing 10 can be embedded in the groove of the door and window frame 50 first, and after adjusting the position of the housing 10, the other side is also embedded in the groove of the door and window frame 50, so that the housing 10 can be completely embedded in the groove of the door and window frame 50. After aligning the positioning block with the positioning hole 51, the housing 10 can be initially positioned and installed in the groove of the door and window frame 50 under the action of the elastic member, and then the housing 10 can be further fixed and installed very conveniently.

[0035] 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.
