Description

Technical Field

[0001] The utility model relates to the field of door locks, in particular to a card-inserting door lock. Background Art

[0002] A card-insertion door lock is a door lock manufactured using the identification and reading functions of an IC card and a card reader. The IC card is inserted into the door lock and fits into the card reader inside it. The card reader reads and identifies the IC card data. After identification, the door is unlocked. It is widely used in the hotel and guesthouse industries.

[0003] A common card-insertion door lock has a card slot on the front. By inserting the room card into the inner cavity of the card slot, the room card enters the door lock and contacts the card reader. However, since the card slot on the door lock is mostly directly exposed to the air, dust and other impurities in the air enter the door lock through the card slot, causing contamination of the internal components of the door lock. At the same time, when impurities are between the room card and the card reader, they will block the contact between the room card and the card reader, which may easily cause poor contact between the room card and the card reader.

The protective mechanism 3 prevents impurities such as dust from entering the inner cavity of the card insertion slot 2 into the interior of the door lock body 1. The elastic mechanism 4 is arranged on the protective mechanism 3. The elastic mechanism 4 is used to rebound downward inside the protective mechanism 3. The movable block 33 is driven to rotate by the elastic mechanism 4 to ensure that the movable block 33 stably shields the position of the through slot 32.

[0037] Furthermore, the protection mechanism 3 includes a protection shell 31, a through slot 32, a movable block 33, a mounting hole 34 and a mounting shaft 35. The back of the protection shell 31 is fixedly connected to the top of the front of the door lock body 1. The protection shell 31 is used to install the movable block 33. The card slot 2 is arranged in the inner cavity of the protection shell 31. The through slot 32 is arranged at the bottom of the front of the protection shell 31. The through slot 32 corresponds to the position of the card slot 2. The room card passes through the inner cavity of the through slot 32 and the card slot 2 in turn to enter the inner cavity of the door lock body 1. The movable block 33 is arranged in the inner cavity of the protection shell 31. The movable block 33 is used to move the through slot 32. The movable block 33 is arranged in a long strip shape, and the mounting hole 34 is arranged on one side of the inner wall of the protective shell 31. The mounting hole 34 is used to connect the mounting shaft 35. One end of the mounting shaft 35 is fixedly connected to one side of the top of the movable block 33, and the other end of the mounting shaft 35 is slidably inserted into the inner cavity of the mounting hole 34. The top of the movable block 33 is rotatably connected with the inside of the protective shell 31 through the mounting shaft 35, so that the movable block 33 rotates around the mounting shaft 35. When the room card slides and inserts into the inner cavity of the through groove 32, the movable block 33 is squeezed, so that the movable block 33 rotates upward around the mounting shaft 35.

[0038] Furthermore, the elastic mechanism 4 includes a movable rod 41, a connecting shaft 1 42, a connecting seat 1 43, a connecting rod 44, a connecting shaft 2 45, a connecting seat 2 46, a compression spring 47 and a fixed block 48. The movable rod 41 is arranged on one side of the back of the movable block 33. The top of the movable rod 41 is hollow and used to install the connecting rod 44. The movable rod 41 moves with the movable block 33. The connecting shaft 1 42 is fixedly connected with the bottom of the movable rod 41. The connecting seat 1 43 is fixedly connected to one side of the back of the movable block 33. The connecting seat 1 43 The two ends of the connecting shaft 42 are rotatably connected, and the bottom of the movable rod 41 is rotatably connected to one side of the back of the movable block 33 through the connecting shaft 42 and the connecting seat 43, so that the bottom of the movable rod 41 rotates around the connecting shaft 42, and the bottom of the connecting rod 44 is slidably connected to the inner cavity of the movable rod 41. The bottom of the connecting rod 44 slides in the inner cavity of the movable rod 41, and the connecting shaft 45 is fixedly connected to the top of the connecting rod 44. The connecting seat 46 is fixedly connected to the back of the inner wall of the protective shell 31. The connecting seat 46 The two ends of the connecting shaft 45 are rotatably connected and interlaced. The top of the connecting rod 44 is rotatably connected through the connecting shaft 45 and the connecting seat 46, so that the top of the connecting rod 44 rotates around the connecting shaft 45. The compression spring 47 is movably sleeved with the top of the connecting rod 44. The compression spring 47 is used to push the fixed block 48 and the movable rod 41. The fixed block 48 is fixedly interlaced with the top of the movable rod 41. The upper surface of the fixed block 48 is in contact with the bottom end of the compression spring 47. The fixed block 48 moves with the top of the movable rod 41 to push the movable rod 41. The compression spring 47 is squeezed and deformed, and the movable block 33 rotates upward around the installation axis 35, driving the movable rod 41 and the connecting rod 44 to rotate together. The movable rod 41 slides upward along the connecting rod 44, driving the fixed block 48 to squeeze and deform the compression spring 47, and the movable block 33 is rotated to open. The elastic action of the compression spring 47 is used to push the fixed block 48 and the movable rod 41 back to the initial position, so that the movable rod 41 slides downward along the connecting rod 44, pushing the movable block 33 to rotate downward, and the movable block 33 blocks the through groove 32.
