[0029] Example 1

[0030] This embodiment provides an indoor door lock with a hidden installation hole function, such as Figure 1 As shown, it includes two external mounting plates 1, both ends of the external mounting plates 1 are rotatably connected with handles 2, and the sides of the two external mounting plates 1 are fixedly installed with a docking rod 3. The two docking rods 3 are staggered, and the end of the docking rod 3 on the external mounting plate 1 is inserted into the interior of the other external mounting plate 1.

[0031] like Figure 2 and Figure 3 As shown, an installation component 4 is provided at the external installation plate 1, and the installation component 4 includes an intermediate block 41, a docking hole 42, a clamping block 43, a positioning plate 45 and a spring sheet 46. A docking hole 42 is provided on the intermediate block 41, and the docking rod 3 passes through the docking hole 42. The inner wall of the intermediate block 41 is slidably connected to two symmetrically arranged clamping blocks 43. A groove 5 is provided in the middle of the docking rod 3. The clamping block 43 adopts a rectangular block structure. The width of the clamping block 43 is the same as the width of the groove 5 in the middle of the docking rod 3. The clamping block 43 is clamped in the groove 5 of the docking rod 3, thereby fixing the position of the docking rod 3, and the external installation plate 1 and the docking rod 3 can be fixed on the door.

[0032] like Figure 3 and Figure 4 As shown, positioning plates 45 are fixedly installed on the upper and lower sides of the middle block 41, and a spring sheet 46 is elastically connected between the clamping block 43 and the positioning plate 45. The spring sheet 46 provides support force for the clamping block 43 to prevent the clamping block 43 from detaching from the groove 5.

[0033] The two clamping blocks 43 are respectively clamped with the two docking rods 3. A docking rod 3 is fixedly installed on the side of each of the two external mounting plates 1. The two docking rods 3 are staggered. By clamping the two docking rods 3, the positions of the two external mounting plates 1 can be fixed.

[0034] The inner wall of the middle block 41 is slidably connected with an extrusion plate 44, and the end of the extrusion plate 44 extends from the right side of the middle block 41. The spring sheet 46 is located on the extension line of the end of the extrusion plate 44. By pressing the extrusion plate 44 to squeeze the spring sheet 46, the spring sheet 46 is bent, so that the blocking block 43 is moved away from the docking rod 3, and the external mounting plate 1 can be removed from the door.

[0035] One end of the limiting block away from the clamping block 43 is rotatably connected to the pulling plate 47 . Initially, the pulling plate 47 is flush with the side surface of the guide plate 61 .

[0036] A horizontal limiting block is provided at the end of the clamping block 43 . The limiting block adopts a U-shaped structure. The positioning plate 45 is located in the opening of the limiting block, thereby limiting the positioning plate 45 .

[0037] In this embodiment, two clamping blocks 43 are respectively inserted into the grooves 5 of the two docking rods 3 to fix the positions of the two docking rods 3, thereby fixing the two external mounting plates 1 on the external mounting plate 1 to achieve a quick installation effect. By pressing the extrusion plate 44 to squeeze the spring sheet 46, the spring sheet 46 is bent, and the clamping block 43 is moved away from the docking rod 3, and the external mounting plate 1 can be removed from the door. After installation, there are no mounting screw holes on the door lock, thereby improving the security of the lock.

[0038] Example 2

[0039] Based on Example 1, this embodiment proposes an indoor door lock with a hidden mounting hole function, such as Figure 5 As shown, an extension piece 6 is provided on the side of the middle block 41. The extension piece 6 includes a guide plate 61 and an extension block 62. The guide plate 61 slides inside the middle block 41. The extension block 62 is fixedly installed at the end of the guide plate 61. At the same time, the guide plate 61 not only plays a guiding role, but also blocks the gap between the extension block 62 and the middle block 41.

[0040] A round hole and a square hole are provided on the extension block 62, and the docking rod 3 passes through the round hole to fix the position of the extension block 62 and the middle block 41. A magnet 63 is fixedly installed on the side of the extension block 62, and an iron sheet is installed at the position where the door lock is installed on the door. Since the position of the middle block 41 is fixed, the magnet 63 will drive the extension block 62 to move toward the iron sheet, thereby adapting to the width of the lock installation opening on the door.

[0041] In this embodiment, through the cooperation between the magnet 63 and the iron sheet, the magnet 63 will drive the expansion block 62 to move toward the iron sheet, thereby adapting to the width of the lock installation opening on the door and improving the installation adaptability.

[0042] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
