[0002] Smart door locks are composite locks that are different from traditional mechanical locks and are more intelligent and simple in terms of user security, identification, and management. They are the executive components of door locks in access control systems. Common smart door locks include magnetic card locks, fingerprint locks, iris recognition locks, etc. They are mostly used in banks, government departments (focusing on security), hotels, etc. With the development of smart door locks, smart door locks are also developing towards networking, and users can control them directly on their mobile phones. Although smart door locks are relatively mature, there are still some problems.
[0003] Traditional smart identification door locks are generally installed directly on the surface of the door, and the overall firmness is not very strong. When encountering theft by criminals, the entire door lock can be easily removed directly from the surface of the door, and then the lock core inside the door is damaged, which causes great losses to the user and the overall security is not very good, giving criminals an opportunity to take advantage.

[0016] Figure 2 This is a schematic diagram of the exploded structure of an anti-disassembly smart door lock according to an embodiment of the utility model;
[0017] Figure 3 The figure is a schematic diagram of the structure of a protective cover in one embodiment of the utility model. DETAILED DESCRIPTION
[0018] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:
[0019] like Figures 1 to 3 The embodiment of the utility model shown preferably provides an anti-disassembly and assembly smart door lock, including a lock body 1, a handle 2 is rotatably provided on the outer side of the lock body 1, a transmission member 3 connected to the handle 2 is provided on the inner side of the lock body 1, one end of the transmission member 3 has a mounting groove 4 that can be connected to a square rod, a flange 5 is circumferentially provided on the inner side of the lock body 1, a mounting cavity 6 is formed on the inner side of the flange 5, connecting holes 7 connected to the mounting cavity 6 are arranged at intervals on the lock body 1, a protective cover 8 is provided on the outer side of the lock body 1 through a magnet magnetic cover, a limiting rod 9 that can cooperate with the connecting hole 7 is provided on the inner side of the protective cover 8, one end of the limiting rod 9 extends into the mounting cavity 6 and is circumferentially provided with a card slot 10, a limiting member 11 that can be engaged with the card slot 10 is rotatably provided in the mounting cavity 6 through a torsion spring, and a transmission component 12 that can drive the limiting member 11 to rotate with the transmission member 3 and disengage from the card slot 10 is provided in the mounting cavity 6.
[0020] Specifically, a cover protective cover is added to the outside of the lock body, and the protective cover is kept in contact with the lock body by magnets to protect the lock body, and a limiting rod of the protective cover passes through the connection hole of the lock body and extends into the installation cavity inside the lock body, and a limiting member in the installation cavity is kept in contact with the card slot of the limiting rod by a torsion spring, thereby realizing the connection state of the protective cover fastening the cover to the lock body;
[0021] And when the lock body is in an unlocked handle rotatable state, the user can rotate the handle to drive the limit member out of engagement with the slot through the transmission component, so that the protective cover can be removed from the lock body. Conversely, when the lock body is in a locked handle and cannot be rotated state, the limit member cannot be driven out of the slot through the transmission action of the transmission component, so as to better protect the lock body.
[0022] Furthermore, the transmission member 12 includes a ring gear 13 and racks 14 respectively meshed with both sides of the ring gear 13. The ring gear 13 is sleeved on one end of the transmission member 3 and can rotate with the transmission member 3. A guide seat 15 is provided in the installation cavity 6. A first guide hole is formed through one side of the guide seat 15. The rack 14 is inserted into the first guide hole. A convex portion 16 is provided at one end of the rack 14. The convex portion 16 is movably abutted against one side of the stopper 11 with the rack 14. Specifically, when the user rotates the handle, the ring gear is driven to rotate through the transmission member, and then the rack is driven to move axially along the first guide hole of the guide seat through the ring gear. At this time, the convex portion on the rack moves and presses against one side of the stopper, so that the stopper rotates and disengages from the engagement of the stopper rod slot, thereby facilitating the subsequent manual disassembly and separation of the protective cover from the lock body.
[0023] Furthermore, the protective cover 8 includes a first cover shell 81 and a second cover shell 82. The first cover shell 81 is provided with a connecting rod 83 at one end close to the second cover shell 82. The second cover shell 82 is provided with a second guide hole 84 at one end corresponding to the connecting rod 83. The connecting rod 83 is inserted into the second guide hole 84 so that the first cover shell 81 and the second cover shell 82 can move relatively close to or away from each other. When the limiting rod of the protective cover moves away from the connecting hole of the lock body, the first cover shell and the second cover shell of the protective cover can be relatively separated and moved, so as to give way to the handle position and facilitate the removal of the protective cover.
[0024] Furthermore, a first notch 85 is concavely formed at one end of the first cover shell 81 , and a second notch 86 is concavely formed at one end of the second cover shell 82 . The first notch 85 and the second notch 86 are combined to form a clearance hole that can cooperate with the connection end of the handle 2 .
[0025] Furthermore, there are two limit rods 9 , which are respectively and one-to-one connected to the first cover shell 81 and the second cover shell 82 .
[0026] Furthermore, a slot 87 is formed on one side of the first cover 81. Specifically, the position of the slot corresponds to the position of the password button or fingerprint button of the lock body, so that the password button or fingerprint button of the lock body is exposed for use.
[0027] Furthermore, the protective cover 8 is made of transparent material, thereby increasing the overall aesthetics and facilitating intuitive viewing of the lock body.
[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
