[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0026] like Figures 1 to 6 As shown, the utility model provides a specific embodiment of a lock.

[0027] A lock, reference Figure 1 and Figure 2 The lock includes: a base 1, a driving member 2, a connecting rod 3, a transmission assembly 4, a lock head connecting member 5 and a gear structure 6 having a plurality of gear slots 61. The gear structure 6 and the transmission assembly 4 are both arranged on the base 1, the lock head connecting member 5 is arranged on the transmission assembly 4, one end of the connecting rod 3 is fixedly connected to the transmission assembly 4 and extends into the gear structure 6, and the other end of the connecting rod 3 is connected to the driving member 2.

[0028] Among them, reference Figure 1 and Figure 2The movement of the driving member 2 can drive the connecting rod 3 to move, thereby driving the transmission assembly 4 to move, and driving the lock head connecting member 5 to move. The movement of the transmission assembly 4 can drive the connecting rod 3 to move relative to the gear structure 6 to be inserted into different gear slots 61.

[0029] Specifically, refer to Figure 1 and Figure 2 A lock is a device that combines the functions of a door driver and a door lock. It is usually installed on a door frame and is used to control the opening and closing of a door. It allows the user to lock or unlock the door by rotating the door driver, thereby providing security and portability; a base 1 is used to be fixed to an external door frame; a transmission assembly 4 is arranged on the base 1 for power transmission; a connecting rod 3 is fixed to the transmission assembly 4 for connecting the driver 2 and the transmission assembly 4; the driver 2 is connected to the connecting rod 3 to facilitate the user to lock or unlock the door, and the driver 2 can be stored in the base 1; a lock connector 5 is fixed to the power output end of the transmission assembly 4 for connecting an external lock.

[0030] refer to Figure 1 and Figure 2 The gear structure 6 includes a plurality of gear slots 61. When the user moves the driving member 2, the transmission assembly 4 can drive the connecting rod 3 to different gear slots 61 to limit the connecting rod 3 to different gears, thereby fixing the lock head at different positions, and finally achieving different locking states of the lock.

[0031] In this embodiment, the gear structure 6 includes three gear slots 61, corresponding to the initial position, the middle position and the end position, respectively. The locking states corresponding to the initial position, the middle position and the end position can be set according to actual needs. For example, the initial position is the door lock locking state, the middle position is the door lock opening state, and the end position is the door lock anti-locking state, etc.

[0032] Taking the initial position as the locked state of the door lock, the middle position as the opened state of the door lock, and the end position as the reverse locked state of the door lock as an example, when the door lock is in the opened state, the connecting rod 3 is in the gear slot 61 corresponding to the middle position, and the driving member 2 is perpendicular to the base 1, so as to facilitate opening or closing the door.

[0033] When the door lock state needs to be converted from the open state to the locked state, the connecting rod 3 is driven to move by the driving member 2, so that the transmission assembly 4 moves, so as to drive the lock head connecting member 5 to move, so as to drive the lock head to move and lock; and in the process of the movement of the transmission assembly 4, the connecting rod 3 will be driven to move together, and the connecting rod 3 will be moved out from the gear slot 61 corresponding to the middle position, and moved and limited to the gear slot 61 corresponding to the initial position. At this time, the driving member 2 will be stored in the base 1.

[0034] When the door lock state needs to be converted from the open state to the anti-lock state, the connecting rod 3 is driven to move again through the driving member 2, so that the transmission assembly 4 moves, so as to drive the lock head connecting member 5 to move, and drive the lock head to move and anti-lock; and in the process of the movement of the transmission assembly 4, the connecting rod 3 will be driven to move together, and the connecting rod 3 will be moved out from the gear slot 61 corresponding to the middle position, and moved and limited to the gear slot 61 corresponding to the end position. At this time, the driving member 2 will also be stored in the base 1, and the direction position of the driving member 2 at this time is opposite to the direction position when the door lock is in the locked state.

[0035] Currently, there are many hidden locks on the market. Hidden locks generally have multiple travel points such as open state, locked state and anti-lock state. Existing hidden locks are difficult to achieve accurate positioning during use. The lock bar is difficult to accurately position and is easy to move between multiple travel sections, which poses a safety hazard to the entire locking system.

[0036] In the present embodiment, a lock is designed, including: a base 1, a driving member 2, a connecting rod 3, a transmission assembly 4, a lock head connecting member 5 and a gear structure 6 having a plurality of gear slots 61, and one end of the connecting rod 3 is fixedly connected to the transmission assembly 4 and extends into the gear structure 6, so that in different door lock states, the connecting rod 3 can move and be limited to different gear slots 61 in the gear structure 6, so that the positioning of the lock head in different door lock states is more accurate, and the gear structure 6 can increase the resistance of the connecting rod 3 during movement, effectively preventing the lock head from moving between multiple strokes, so as to increase the safety of the entire locking system.

[0037] In one embodiment, reference Figure 2 and Figure 3 , the gear structure 6 is an elastic member.

[0038] Specifically, refer to Figure 2 and Figure 3 When the connecting rod 3 is connected to the gear structure 6, the elastic force of the gear structure 6 can press the contact surface of the connecting rod 3, thereby increasing the resistance of the connecting rod 3 during movement, effectively preventing the lock head from moving between multiple strokes, and increasing the safety of the entire locking system.

[0039] In one embodiment, reference Figure 2 and Figure 3 A connecting channel 62 is provided between two adjacent gear slots 61 .

[0040] Specifically, refer to Figure 2 and Figure 3The diameter of the connecting channel 62 is smaller than the diameter of the connecting rod 3, and the diameter of the gear slot 61 is smaller than or equal to the diameter of the connecting rod 3. When the connecting rod 3 moves in the connecting channel 62, the inner wall of the connecting channel 62 will be expanded, and the two sides of the connecting channel 62 will generate a clamping force on the connecting rod 3 under the action of elastic force. When the connecting rod 3 moves from the connecting channel 62 to the gear slot 61, since the diameter of the gear slot 61 is larger than the diameter of the connecting channel 62 and smaller than or equal to the diameter of the connecting rod 3, the clamping force on both sides of the connecting rod 3 will be released. At this time, the elastic force generated by the connecting channels 62 at both ends of the gear slot 61 can limit the connecting rod 3 from moving backward or further forward, so as to achieve precise positioning of the lock head, thereby increasing the safety of the entire locking system.

[0041] In one embodiment, reference Figure 2 The transmission assembly 4 includes a gear 41, a first guide block 42 and a second guide block 43. The first guide block 42 is movably arranged on the base 1 and is fixedly connected to the lock connector 5. The second guide block 43 is fixed in the base 1. The gear 41 is arranged between the first guide block 42 and the second guide block 43 and is fixedly connected to the connecting rod 3. The movement of the driving member 2 can drive the connecting rod 3 to move, so as to drive the gear 41 to roll on the second guide block 43, so as to drive the first guide block 42 to move, and drive the lock connector to move.

[0042] Specifically, refer to Figure 1 and Figure 2 The first guide block 42 is movably connected to the base 1, and the second guide block 43 is fixedly connected to the base 1. The first guide block 42 and the second guide block 43 are respectively arranged on opposite sides of the base 1. A first rack is arranged on a side surface of the first guide block 42 facing the second guide block 43, and a second rack is arranged on a side of the second guide block 43 facing the first guide block 42. The gear 41 is arranged between the first guide block 42 and the second guide block 43, and is respectively meshed with the first rack and the second rack.

[0043] refer to Figure 1 and Figure 2 Since the second guide block 43 is fixedly connected to the base 1 and the first guide block 42 is movably connected to the base 1, the gear 41 can move along the second rack when rolling, and drive the first guide block 42 to move together, so that the first guide block 42 moves relative to the base 1, and the longest movement stroke is the sum of the length of the first rack and the length of the second rack.

[0044] In this embodiment, a movable first guide block 42 and a fixed second guide block 43 are designed so that the moving stroke of the first guide block 42 is the sum of the length of the first rack and the length of the second rack, that is, the moving stroke of the lock cylinder is the sum of the length of the first rack and the length of the second rack. The moving stroke of the second guide block 43 is effectively increased without increasing the diameter of the gear 41 to ensure miniaturization. This solution not only meets the installation size requirements, but also meets the stroke requirements for complete locking.

[0045] In one embodiment, reference Figure 1 and Figure 4 The base 1 is provided with a first receiving groove 11 for receiving the driving member 2 and a second receiving groove 12 for receiving the transmission assembly 4, and the first receiving groove 11 and the second receiving groove 12 are arranged in opposite directions.

[0046] Specifically, refer to Figure 1 and Figure 4 The first accommodating groove 11 is mainly used to accommodate the driving member 2, and the second accommodating groove 12 is used to accommodate the gear 41, the first guide block 42 and the second guide block 43. The first accommodating groove 11 and the second accommodating groove 12 are arranged side by side and the notches are arranged in reverse to reduce the space occupied by the two. The connecting rod 3 runs through the first accommodating groove 11 and the second accommodating groove 12. One end of the connecting rod 3 is connected to the driving member 2 in the first accommodating groove 11, and the other end of the connecting rod 3 is fixedly connected to the gear 41 in the second accommodating groove 12. Pulling the driving member 2 can drive the connecting rod 3 to move, thereby driving the gear 41 to move, thereby driving the first guide block 42 to move along the notch of the second accommodating groove 12, and driving the lock head connecting member 5 to move, and driving the external lock head to move to achieve different locking states; wherein, the driving member 2 can move and be stored and hidden in the first accommodating groove 11 to provide better aesthetics and higher safety.

[0047] In one embodiment, reference Figure 1 and Figure 4 The second receiving groove 12 includes a first receiving portion 121 and a second receiving portion 122 , the first guide block 42 is disposed in the first receiving portion 121 , and the gear 41 and the second guide block 43 are both disposed in the second receiving portion 122 .

[0048] Specifically, refer to Figure 1 and Figure 4The first accommodating portion 121 is used to accommodate the first guide block 42, and the second accommodating portion 122 is used to accommodate the gear 41 and the second guide block 43.

The first guide block 42 is arranged at the connection between the second accommodating portion 122 and the first accommodating portion 121, and the length of the first guide block 42 is the same as the length of the second guide block 43. The length of the first accommodating portion 121 is greater than or equal to the sum of the lengths of the first guide block 42 and the second guide block 43 so as to provide a moving space for the first guide block 42; the gear 41 is arranged in the second accommodating portion 122 to connect the first guide block 42 and the second guide block 43.

[0049] In one embodiment, reference Figure 1 , Figure 4 and Figure 5 A positioning portion 13 is provided between the first accommodating groove 11 and the second accommodating groove 12 , one end of the connecting rod 3 is provided in the first accommodating groove 11 and fixed to the driving member 2 , and the other end of the connecting rod 3 passes through the positioning portion 13 and extends into the second accommodating groove 12 and is fixed to the gear 41 .

[0050] Specifically, refer to Figure 1 , Figure 4 and Figure 5 The positioning portion 13 is used to avoid the connecting rod 3 to facilitate the connecting rod 3 to pass through the first accommodating groove 11 and the second accommodating groove 12. The length of the positioning portion 13 is adapted to the length of the second rack. When the gear 41 rolls, the gear 41 moves along the first rack and drives the second guide block 43 to move together. When the gear 41 moves along the second rack, the connecting rod 3 will also move in the positioning portion 13. By setting the length of the positioning portion 13 to be adapted to the length of the second rack, a complete moving space can be provided for the connecting rod 3.
