TECHNICAL FIELD
[0001] The utility model relates to the field of door and window fittings, in particular to a self-adaptive adjusting lock for sliding window. BACKGROUND
[0002] In the sliding door and window, in order to ensure the safe locking of the movable door and window sash, a lock is installed. The lock is mainly composed of a lock shell and a lock hook. The lock shell is usually installed on the sash frame of a door and window, and the lock shell has a lock slot with a side opening. The lock hook is correspondingly installed on the sash frame of the adjacent door and window. During the closing of the door and window, the movable window sash is moved so that the lock hook can be smoothly inserted into the lock slot to achieve effective locking. However, if the installation position of the lock hook is deviated, the lock hook may not be able to be smoothly inserted into place due to the inability to accurately align the lock slot, resulting in the door and window being unable to be completely closed. Thus, the sealing and safety of the door and window are affected, and the user's use is inconvenient. SUMMARY
[0003] Therefore, in view of the above problems, the utility model provides a self-adaptive adjusting lock for sliding window.
[0004] The purpose of the utility model can be achieved through the following technical solutions:
[0005] A self-adaptive adjusting lock for sliding window, comprising a lock shell installed on the inner side of a first window frame and a lock hook installed on a second window frame at a position corresponding to the lock shell. The lock shell has an internal cavity. An active block is installed in the cavity. The active block has a lock slot with a side opening. The lock shell has an exposed opening that exposes the lock slot. An elastic member is installed in the upper and lower parts of the cavity to abut against the upper and lower parts of the active block.
[0006] According to the above technical solution, in the unlocked state, the lock slot of the active block is located in the middle position under the action of the upper and lower elastic members. When the installation position of the lock hook is slightly deviated, the lock hook cannot be aligned with the lock slot. When locking is required, the lock hook contacts the lock slot and presses the active block to adaptively shift upward or downward in the cavity, ensuring that the lock hook can be freely clamped into the lock slot, thereby achieving stable locking of the door and window.
[0007] In the specific embodiment of the utility model, the notch of the active block has a stepped structure. The notch has a clamping groove on the upper and lower sides. A fixed block is arranged in the upper and lower parts of the cavity. The fixed block has a fixed hole. First notches are formed in the opposite side walls of the two fixed holes. Second notches are formed in the clamping groove at positions corresponding to the first notches. One end of the elastic member is fixed in the fixed hole, and the other end extends into the corresponding clamping groove and abuts against the notch. With this structure, the two elastic members not only provide support for the active block, but also press the active block in the cavity.
[0008] In the specific embodiment of the utility model, the elastic member comprises a cylindrical connecting portion installed in the fixing hole and two hook-shaped abutting portions symmetrically bent on the connecting portion, the end portion of the abutting portion is abutted on the notch, and the free end is abutted on the inner wall of the corresponding clamping groove.
[0009] In the specific embodiment of the utility model, the fixing hole is a through hole, a via hole is formed on the connecting portion, a bolt is installed in the via hole, the end of the bolt is screwed on the window frame through the via hole, and the shell is fixed on the window frame.
[0010] In summary, the utility model is pressed by two elastic members to prevent the movable block from falling off the cavity, and the two elastic sheets are respectively abutted on the two sides of the upper and lower movable blocks, so that when the installation position of the lock hook is slightly deviated, the lock hook is in contact with the lock groove and presses the movable block to adaptively shift upward or downward in the cavity when locked, the lock hook can be clamped into the lock groove, and the door and window can be completely closed.

[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0017] Please refer to Figure 3 and Figure 4 The utility model discloses a self-adaptive adjustment lock for sliding window, which comprises a lock shell 10 installed on the inner side of a first window frame 9 and a lock hook 7 installed on a second window frame 8 at the position corresponding to the lock shell 10.
[0018] combined Figure 1 andFigure 2 As shown in the drawings, the lock housing 10 has a cavity 11 inside. A movable block 20 is installed in the cavity 11. The movable block 20 has a U-shaped lock slot 21 with a side opening. The lock housing 10 has an exposed opening 12 with a side opening to expose the lock slot 21.
[0019] Two elastic members 30 are installed in the upper and lower parts of the cavity 11 to abut against the upper and lower parts of the movable block 20. In this way, when the lock is not locked, the lock slot 21 of the movable block 20 is located in the middle position under the action of the two elastic members 30. When the installation position of the lock hook 7 is slightly deviated and cannot be aligned with the lock slot 21, the lock hook 7 contacts the lock slot and presses the movable block 20 to adaptively shift upward or downward in the cavity when locking is needed, so as to ensure that the lock hook 7 can be freely clamped into the lock slot.
[0020] The movable block 20 has a stepped notch 22. The notch 22 has a clamping groove 23 on each of the upper and lower sides. The cavity 11 has a fixed block 13 on each of the upper and lower parts. Each fixed block 13 has a fixed hole 14. The opposite side walls of the two fixed holes 14 are provided with a first notch 15. The clamping groove 23 is provided with a second notch 24 corresponding to the position of the first notch 15. One end of the elastic member 30 is fixed in the fixed hole 14, and the other end extends into the corresponding clamping groove 23 and abuts against the notch 22. In this way, the two elastic members 30 not only provide support for the movable block 20, but also press the movable block in the cavity.
[0021] In this embodiment, the elastic member 30 includes a cylindrical connecting part 31 installed in the fixed hole 14, and two hook-shaped abutting parts 32 symmetrically bent on the connecting part. The bent end of the abutting part 32 abuts against the notch 22, and the free end abuts against the inner wall of the corresponding clamping groove 23.
[0022] In this embodiment, the fixed hole 14 is a through hole. The connecting part 31 is provided with a through hole 33. A bolt is installed in the through hole 33. During assembly, the end of the bolt is screwed into the window frame through the through hole to fix the housing on the window frame.
[0023] As described above, the movable block is pressed by the two elastic members in the utility model to prevent the movable block from falling out of the cavity. Meanwhile, the two elastic members abut against the upper and lower sides of the movable block. When the installation position of the lock hook is slightly deviated, the lock hook contacts the lock slot and presses the movable block to adaptively shift upward or downward in the cavity when locking is needed, so as to ensure that the lock hook can be clamped into the lock slot, thereby ensuring that the door and window can be completely closed.
[0024] The above has carried out the detailed description to one embodiment of the utility model, but the content described is only the preferred embodiment of the utility model, cannot be considered for limiting the implementation scope of the utility model. All equal changes and improvements etc. that are made in the utility model application scope should still belong to the patent coverage scope of the utility model.
