[0022] The utility model discloses a lock structure, which is installed on the door leaf 10. Figures 1 to 4The lock structure includes a lock body 1, a fixed cover 2 and a handle 3. The fixed cover 2 is fixedly connected to the door leaf 10 and forms a storage space (not shown) for accommodating the lock body 1 with the door leaf 10. On the one hand, the lock body 1 is fixedly installed on the door leaf 10 by the fixed cover 2, and the lock body 1 is installed in the storage space, which avoids the lock body 1 from being offset during use and causing the lock structure to fail. On the other hand, the lock body 1 is fixed by the fixed cover 2, and there is no need to drill additional holes on the edge of the door leaf 10 and use bolts to fix the lock body 1, which simplifies the installation steps of the lock structure and saves manpower and material costs during installation. The handle 3 includes an inner handle 31 and an outer handle 32. The inner handle 31 and the outer handle 32 are respectively arranged on both sides of the door leaf 10, and the inner handle 31 is connected to the fixed cover 2, hiding the lock body 1 in the fixed cover 2, making the entire lock structure simple and beautiful. The fixing part 4 passes through the fixing cover 2 and the lock body 1 in sequence in a direction parallel to the door leaf 10, and the fixing part 4 is located at the end away from the edge of the door leaf 10, so that the fixing cover 2 abuts against the edge of the door leaf 10. On the one hand, it ensures that when the lock body 1 is fixed to the door leaf 10, there is no need to punch a second hole on the edge of the door leaf 10 to fix the lock body 1, which simplifies the installation steps of the lock structure; on the other hand, it ensures stable fixation between the fixing cover 2 and the door leaf 10, avoiding unnecessary shaking of the lock body 1 in the accommodating space when opening and closing the lock, which affects the normal use of the lock structure.

[0023] In addition, the fixing member 4 is arranged inside the handle member 3 and is not exposed, so that when the entire lock structure is connected, there is no connection mark on the outside, which ensures the aesthetics of the lock structure and enhances its industry competitiveness.

[0024] In some embodiments, the inner handle 31 includes a top cover. When the fixing member 4 is used to fix the handle member 3, the lock body 1 and the fixing cover 2, the top cover can be opened, and the fixing member 4 can be passed through the connecting hole in the inner handle 31 to fix the lock structure. After the fixation is completed, the top cover can be buckled to achieve a seamless installation and fixation of the lock body 1. There is no need to drill additional holes on the edge of the door leaf 10 and use bolts to fix the lock body 1, which reduces the difficulty of installing the lock structure.

[0025] It can be understood that the fixing part 4 can be a fixing bolt. During installation, the fixing bolt can be tightened to different degrees according to actual needs to achieve stable fixation of the lock body 1; during disassembly, the lock body 1 can be separated from the door leaf 10 at a certain slow speed to prevent the lock body 1 from falling and damaging the lock body 1 during disassembly.

[0026] In some embodiments, the lock body 1 includes an inner plate 11 and a lock tongue 12 disposed on the inner plate 11. The door leaf 10 includes a lock hole 8 disposed at an edge thereof, and a groove 81 is disposed on the side of the lock hole 8 away from the lock body 1. The inner plate 11 is received in the lock hole 8 and abuts against the groove 81. At this time, the connection between the fixing member 4 and the fixing cover 2 can have a certain margin. The inner plate 11 abuts against the lock hole 8. The lock body 1 is fixed to the door leaf 10 via the fixing cover 2 and its own inner plate 11, further ensuring the stable fixation of the lock body 1 to the door leaf 10.

[0027] The lock structure also includes a buckle box member 9, which is mounted on the door frame (not shown). The buckle box member 9 includes a buckle slot 91 corresponding to the inner panel 11. The buckle slot 91 is used to accommodate a lock tongue 12 when the lock structure is closed. The lock tongue 12 extends out of the lock hole 8 and is accommodated in the buckle slot 91. When the lock structure is opened, the lock tongue 12 retracts into the lock hole 8. The outer surface of the lock tongue 12 is flush with the inner panel 11. This ensures that the door leaf 10 installed with the lock structure can be concealed when the door is unlocked, ensuring the overall aesthetics of the door leaf 10.

[0028] In order to stably fix the lock body 1 to the door leaf 10, in some embodiments, the fixing cover 2 includes a connecting plate 21 and a side plate 22 located at the edge of the connecting plate 21. The connecting plate 21 is connected to the inner handle 31, and the fixing member 4 passes through the connecting plate 21 to fix the lock body 1 and the door leaf 10. The side plate 22 and the connecting plate 21 form a accommodating space where the lock body 1 is located, and the connecting plate 21 abuts against the door leaf 10, further ensuring the stability of the abutment between the fixing cover 2 and the edge of the door leaf 10, and preventing the lock body 1 from shifting due to the shifting of the fixing cover 2 when the lock body 1 is located inside the fixing cover 2, which would affect the normal use of the entire lock structure.

[0029] In some embodiments, the distance between the parallel side panels 22 is smaller than the width of the lock body 1, ensuring that when the fixing cover 2 is used to fix the lock body 1, the fixing cover 2 can fully abut against the lock body 1, thereby enhancing the stability of the lock body 1 installed on the door leaf 10.

[0030] In some embodiments, a through-hole 20 is provided on the side panel 22 on the side away from the edge of the door leaf 10. The lock body 1 includes a mounting hole 10, which is arranged correspondingly to the through-hole 20. The fixing member 4 passes through the mounting hole 10 and the through-hole 20 in sequence to secure the lock body 1, preventing the lock body 1 from shifting unnecessarily under the influence of gravity, which could affect the normal operation of the entire lock structure. Furthermore, the connection hole provided on the fixing cover 2 is concealed at the junction of the inner handle 31 and the fixing cover 2, eliminating any connection marks on the overall appearance of the lock structure and enhancing the external aesthetics of the entire lock structure.

[0031] It can be understood that there is inevitably a certain installation gap between the fixed cover 2 and the lock body 1. During actual use, a certain amount of wear will occur between the fixed cover 2 and the lock body 1, which reduces the service life of the lock body 1. Therefore, in some embodiments, the lock structure also includes a first buffer pad (not shown in the figure), which abuts against the connecting plate 21 and the lock body 1 to eliminate the installation gap between the lock body 1 and the fixed cover 2, thereby improving the stability of the lock body 1 fixed on the door leaf 10, enhancing the service life of the fixed cover 2 and the lock body 1, and reducing maintenance costs.

[0032] Furthermore, in actual use, the door leaf 10 may be a wooden door, a glass door, or the like, and the surface of the door leaf 10 is smooth, and the hardness thereof is different from that of different types of lock bodies 1. In order to prevent the door leaf 10 from being crushed when the fixing member 4 is tightened and the lock body 1 is clamped, in some embodiments, the lock structure further includes a second buffer pad 5, which abuts between the lock body 1 and the door leaf 10. On the one hand, direct contact between the door leaf 10 and the lock body 1 can be avoided, and the second buffer member acts as a buffer between the two, thereby avoiding damage to both the door leaf 10 and the lock body 1 and reducing maintenance costs. On the other hand, since the surface smoothness of different door leaves 10 is different, the surface roughness of the contact surface between the door leaf 10 and the lock body 1 is increased by adding the second buffer pad 5, thereby further fixing the lock body 1 and avoiding relative sliding between the door leaf 10 and the lock body 1 during the door opening and closing process, which may cause malfunction of the lock structure.

[0033] It can be understood that the second buffer pad 5 is a silicone member or other material with elastic and impact-resistant properties to absorb and alleviate the locking force brought by the fixing member 4 when the lock body 1 is fixed on the door leaf 10, and reduce the vibration between the door leaf 10 and the lock body 1 when the door is opened and closed, thereby avoiding relative sliding between the door leaf 10 and the lock body 1 during the process of opening and closing the door.

[0034] In some embodiments, the lock structure further includes a rotating core 6, which passes through the lock body 1 and is disposed between the inner handle 31 and the outer handle 32. The lock structure is opened and closed by the control of the inner handle 31 and the outer handle 32. When multiple fixing members 4 and connecting holes are provided, they should be arranged symmetrically around the rotating core 6 to prevent the fixing members 4 and the connecting holes provided on the fixed cover 2 from being exposed due to the rotation of the inner handle 31 and the outer handle 32, thereby affecting the fixing fastening of the fixing members 4 and the overall aesthetics.

[0035] In addition, the lock structure also includes a square tube 7, which is mounted on the outside of the rotating core 6 and passes through the lock body 1. On the one hand, when the lock body 1 is installed on the door leaf 10, it assists in installing the rotating core 6 and ensures the correspondence between the lock structure and the door leaf 10; on the other hand, the square tube 7 can also be used to adjust the position of the lock structure so that it fits closely with the door leaf 10, thereby ensuring the normal use and safety of the lock structure.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
