Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of lockset, especially a kind of electronic lockset of embedded installation. BACKGROUND

[0002] Lockset is a kind of device for closing and protecting goods, space or facilities, with multiple types and functions. Lockset is generally divided into mechanical lock and electronic lock. Among them, in electronic lock, if there is only single electronic lock component, it will make the door body and frame directly unlocked and separated after unlocking, without additional operation action. However, this structure is slightly poor in safety, and misopening situation is prone to exist.

[0003] Therefore, in most electronic locks, there are electronic lock components and mechanical lock components, and after unlocking the electronic lock component, the mechanical lock component needs to be unlocked by pushing or rotating operation, which can obviously improve the use safety and is accepted by a large number of users. Prior art example, refer to patent document CN222295985U, discloses a hidden lockset, including shell, locking mechanism, elastic element, lock hook and baffle; the shell has accommodating cavity inside, and the outer surface is provided with opening communicating with the accommodating cavity; the locking mechanism and the elastic element, the lock hook and the baffle are installed in the accommodating cavity; the lock hook includes first locking structure and second locking structure, and is in transmission connection with the elastic element, and the lock hook is stretched out or retracted at the opening; the baffle is used to limit the sliding state of the lock hook, so that the lock hook is switched in hidden state, locking state and opening state in turn; wherein, when the locking mechanism acts on the first locking structure, the lock hook is in hidden state; the locking mechanism releases the restriction on the first locking structure, the elastic element drives the lock hook to stretch out from the opening, and the baffle limits the sliding state of the lock hook, so that the locking mechanism can act on the second locking structure, when the locking mechanism acts on the second locking structure, the lock hook is in the locking state, the application technical scheme can accommodate the lock hook, and reduce the occupied space. In the technical example, although it is named as hidden lockset, but it can only achieve the effect of "hidden lock hook", the whole lockset (especially lock shell) is still protruding outward, compared with the lock shell, the space occupied by the "lock hook" can be ignored, therefore, for the whole lock, it is completely impossible to achieve the effect of hidden type.

[0004] In summary, the above technical examples clearly demonstrate that even with an embedded design that allows the lock shell to be concealed within the door or cabinet body, existing lock products often have drawbacks. For user convenience, the handle (or knob) and other operating components protrude from the lock shell's end face, leading to several issues: 1. Increased susceptibility to damage: Protruding handles are prone to collisions with other objects during daily use. For instance, in narrow passages, people or objects passing by may accidentally bump into the handle, causing deformation or damage and affecting its normal use. Frequent collisions can also loosen the connection between the handle and the lock body, reducing the overall stability of the lock and potentially causing the handle to detach. 2. Space consumption: Protruding handles occupy space, which can be inconvenient for doors or cabinets with limited space. For example, in small storage rooms or compact furniture, protruding handles may obstruct the placement of surrounding items or cause collisions when opening and closing the door. 3. Aesthetic Impact: Some design styles prioritize a simple, flat appearance, while protruding handles can disrupt the overall aesthetic and clash with the surrounding environment or decor. This disharmony is particularly noticeable in modern minimalist architecture or home designs. 4. Safety Hazards: Protruding handles can pose a safety threat to children or people with mobility issues. Children may trip or be scratched while playing, and people with mobility issues may bump into the handles, leading to falls or other accidents. In public places such as shopping malls and schools, excessively protruding handles can also hinder evacuation speed, posing a safety risk in emergencies. 5. Increased Risk of Dust and Dirt Accumulation: Because handles are exposed, they are more susceptible to dust, dirt, and various pollutants, requiring more frequent cleaning and maintenance. Furthermore, dirt can accumulate in hard-to-clean corners and crevices, affecting the handle's appearance and hygiene. Summary of the Invention

The working mechanism of the state switching mechanism 8 is that: when the state switching mechanism 8 is in the limiting movement state, the telescopic shell 3 is retracted into the mounting chamber 11 to ensure that the telescopic shell 3 does not protrude from the outer end surface of the fixed outer shell 1; at the same time, the fixed outer shell 1 is embeddedly installed, so that the overall lock will be fully hidden relative to the door cabinet body 91. Thus, the defects of being easy to collide and damage, occupying space, being easy to be contaminated with dust and stains are eliminated, the safety hidden danger is solved, and the aesthetic appearance is improved. When the state switching mechanism 8 is in the release position state, the telescopic shell 3 at least partially extends out of the fixed outer shell 1 under the action of the elastic member 7 to respond to the second unlocking operation of the user, thereby unlocking the mechanical hand straight assembly.

The user presses the telescopic shell 3, and the switching buckle 81 on the rotating support 2 is guided by the first guide block 82 to move out of the state holding groove 85 through the separation side 851; then the user releases the telescopic shell 3, and the telescopic shell 3 is guided by the second guide block 83 and rebounded by the elastic member 7 to extend outward, so that the telescopic shell 3 at least partially extends out of the fixed outer shell 1, and the switching buckle 81 on the rotating support 2 moves to the inner side of the second guide block 83, and the state switching mechanism 8 switches to the release position state; 2. The user presses the telescopic shell 3 again, and the telescopic shell 3 is guided by the second guide block 83 to enter the state holding groove 85 through the entry side 852, and the state switching mechanism 8 switches to the limited motion state; 3.
