Description

Technical Field

[0001] This utility model relates to a door lock, and more particularly to a glass door lock. Background Technology

[0002] Existing glass door locks are installed on glass doors using a clamping method. Glass door locks are locks with multiple unlocking methods. Generally, they use a front inner lock body and an outer lock body clamped onto opposite sides of the glass door to achieve locking or unlocking. Existing glass door locks typically have several unlocking mechanisms, such as unlocking or locking with a mechanical key, unlocking or locking with a knob located inside the door, unlocking or locking with a password entered via a touchscreen, or unlocking or locking with fingerprint or facial recognition. All existing unlocking methods rely on a rotating main shaft that drives a lever to operate the bolt mechanism. To coordinate the movement of multiple unlocking mechanisms, multiple [unclear - possibly referring to a specific mechanism or component] are installed on the main shaft. The gears on the main shaft mesh with different unlocking mechanisms. The coordinated movement of multiple unlocking mechanisms makes the entire unlocking device structurally complex, and the assembly precision of multiple unlocking mechanisms in glass door locks is also greatly improved. In order to accommodate the high-precision and complex coordinated movement of multiple unlocking mechanisms, existing designs often use toothed gears to avoid mutual interference between multiple unlocking mechanisms. However, toothed gears are complex to manufacture and costly. Even if a toothed gear design is adopted, it cannot reduce the problem of the overall complex structure of the unlocking device. Therefore, the market needs a glass door lock with a simple structure in which multiple unlocking mechanisms operate independently and do not interfere with each other. Utility Model Content

[0003] This utility model provides a glass door lock to solve the problem of complex overall structure of the unlocking device caused by multiple unlocking mechanisms in existing glass door locks being driven by a single main shaft, and the problem of assembly precision of multiple unlocking mechanisms in Chinese glass door locks.

[0004] According to one aspect of the present invention, a glass door lock is provided, comprising:

[0005] The connector has a U-shaped structure.

[0006] An outer lock body is located on one side of the connector;

[0007] The inner lock body is located on the other side of the connector, and a locking tongue mechanism is provided on the inner lock body.

[0008] The first unlocking mechanism includes a knob, a rotating shaft, and a lever. The rotating shaft is rotatably mounted on the inner lock body. One end of the rotating shaft extends out of the inner lock body and is fixedly connected to the knob. The other end of the rotating shaft is mounted inside the inner lock body and is fixedly connected to one end of the lever. The other end of the lever is connected to the latch mechanism.

[0009] The second unlocking mechanism is located above the first unlocking mechanism. The second unlocking mechanism includes a lock cylinder, a first gear, a transmission component, a second gear, a fixed shaft, and a first lever pusher. The first gear is located inside the outer lock body and is fixedly located at one end of the lock cylinder. The lock cylinder is at least partially located inside the outer lock body. The fixed shaft and the second gear are located inside the inner lock body. The fixed shaft is fixedly connected to the inner lock body, and the second gear is rotatably connected to the fixed shaft. The first lever pusher is fixedly located below the second gear and is used to push the lever to rotate. The first end of the transmission component meshes with the first gear, and the second end of the transmission component meshes with the second gear.

[0010] Furthermore, the transmission component is located inside the connector. The outer lock body has a first slide groove, through which the first end of the transmission component passes. The inner lock body has a second slide groove, through which the second end of the transmission component passes. The transmission component can slide within the first and second slide grooves.

[0011] Furthermore, the glass door lock also includes a third unlocking mechanism, which includes a motor, a third gear, a fourth gear, and a second lever pusher. The motor, the third gear, the fourth gear, and the second lever pusher are all located inside the inner lock body. The third gear is rotatably mounted on a rotating shaft, and the second lever pusher is fixedly mounted above the third gear. The second lever pusher is used to push the lever to rotate. The fourth gear is fixedly connected to the main shaft of the motor, and the fourth gear meshes with the third gear.

[0012] Furthermore, it also includes a fifth gear, through which the fourth gear meshes with the third gear.

[0013] Furthermore, the lever is provided with a positioning part, and a torsion spring is provided on the positioning part.

[0014] Furthermore, the glass door lock also includes a control circuit board and a touch screen, with the control circuit board electrically connected to the motor and the touch screen, respectively.

[0015] Furthermore, the glass door lock also includes a control circuit board and a fingerprint recognition mechanism, with the control circuit board connected to the motor and the fingerprint recognition mechanism, respectively.

[0016] Furthermore, the glass door lock also includes a control circuit board and a facial recognition mechanism, with the control circuit board electrically connected to the motor and the facial recognition mechanism, respectively.

[0017] The beneficial effects of this utility model are:

[0018] In this invention, the first unlocking mechanism is fixedly connected to a knob at one end of a rotating shaft, and to a lever at the other end. A person inside the room can rotate the knob, which in turn drives the lever to rotate via the rotating shaft. The lever then pushes the latch mechanism forward or backward to lock or unlock. In the second unlocking mechanism, the user inserts a mechanical key into the lock cylinder and rotates it. The lock cylinder drives the first gear to rotate, which in turn drives a transmission component to slide. This sliding transmission component then drives the second gear to rotate around a fixed shaft. Below the second gear, a first lever pusher pushes the lever to rotate, which in turn pushes the latch mechanism forward or backward to lock or unlock.

[0019] In this utility model, the first unlocking mechanism and the second unlocking mechanism move independently and do not interfere with each other. The first unlocking mechanism and the second unlocking mechanism each have their own axis and can move independently without being coaxial. Since the first unlocking mechanism and the second unlocking mechanism are not coaxial, their assembly accuracy is significantly reduced. At the same time, a coaxial and complex first unlocking mechanism and second unlocking mechanism are split into an independently working first unlocking mechanism and second unlocking mechanism, and the structure of each unlocking mechanism is relatively simple.

[0030] Please see Figure 1-4 The image shows a specific embodiment of a glass door lock according to this utility model. It includes:

[0031] Connector 3 has a U-shaped structure;

[0032] The outer lock body 1 is located on one side of the connector 3;

[0033] The inner lock body 2 is located on the other side of the connector 3, and the inner lock body 2 is provided with a locking tongue mechanism 21.

[0034] The first unlocking mechanism 4 includes a knob 41, a rotating shaft 42 and a lever 43. The rotating shaft 42 is rotatably mounted on the inner lock body 2. One end of the rotating shaft 42 extends out of the inner lock body 2 and is fixedly connected to the knob 41. The other end of the rotating shaft 42 is located inside the inner lock body 2 and is fixedly connected to one end of the lever 43. The other end of the lever 43 is connected to the latch mechanism 21.

[0035] The second unlocking mechanism 5 is located above the first unlocking mechanism 4. The second unlocking mechanism 5 includes a lock cylinder 51, a first gear 52, a transmission component 53, a second gear 54, a fixed shaft, and a first lever pusher 55. The first gear 52 is located inside the outer lock body 1 and is fixedly located at one end of the lock cylinder 51. The lock cylinder 51 is at least partially located inside the outer lock body 1. The fixed shaft and the second gear 54 are located inside the inner lock body 2. The fixed shaft is fixedly connected to the inner lock body 2, and the second gear 54 is rotatably connected to the fixed shaft. The first lever pusher 55 is fixedly located below the second gear 54 and is used to push the lever 43 to rotate. The first end of the transmission component 53 meshes with the first gear 52, and the second end of the transmission component 53 meshes with the second gear 54.

[0036] In this embodiment, the first unlocking mechanism 4 is fixedly connected to a knob 41 at one end of a rotating shaft 42, and to a lever 43 at the other end of the rotating shaft 42. A person inside the room can rotate the knob 41, which drives the lever 43 to rotate via the rotating shaft 42. The lever 43 pushes the bolt mechanism 21 forward or backward to unlock or lock the glass door. In the second unlocking mechanism 5, the user inserts the mechanical key into the lock cylinder 51 and rotates it. The lock cylinder 51 drives the first gear 52 to rotate, which drives the transmission component 53 to slide. The sliding transmission component 53 then drives the second gear 54 to rotate around a fixed axis. The first lever pusher 55 below the second gear 54 pushes the lever 43 to rotate, which in turn pushes the bolt mechanism 21 forward or backward to unlock or lock the glass door.

[0037] In this embodiment, the first unlocking mechanism 4 and the second unlocking mechanism 5 move independently without interfering with each other. The first unlocking mechanism 4 and the second unlocking mechanism 5 each have their own axis and can move independently without being coaxial. Since the first unlocking mechanism 4 and the second unlocking mechanism 5 are not coaxial, their assembly accuracy is significantly reduced. At the same time, a coaxial and complex first unlocking mechanism 4 and the second unlocking mechanism 5 are split into two independently working first unlocking mechanism 4 and the second unlocking mechanism 5. The structure of each unlocking mechanism is relatively simple.

[0038] In one embodiment, the transmission member 53 is disposed inside the connector 3. The outer lock body 1 is provided with a first slide groove, and the first end of the transmission member 53 passes through the first slide groove. The inner lock body 2 is provided with a second slide groove, and the second end of the transmission member 53 passes through the second slide groove. The transmission member 53 can slide within the first slide groove and the second slide groove.

[0039] After the user inserts the mechanical key into the lock cylinder 51 and turns it, the transmission component 53 slides left and right under the drive of the first gear 52. In order to prevent the transmission component 53 from interfering with other objects during the sliding process and affecting the locking or unlocking function of the glass door lock, the transmission component 53 is set inside the connector 3. The connector protects the transmission component 53 and prevents the transmission component 53 from being interfered with during the sliding process.

[0040] In one implementation, please refer to Figure 5 As shown, the glass door lock also includes a third unlocking mechanism 6, which includes a motor 61, a third gear 63, a fourth gear 62, and a second lever pusher 64. The motor 61, the third gear 63, the fourth gear 62, and the second lever pusher 64 are all located inside the inner lock body 2. The third gear 63 is rotatably mounted on the rotating shaft 42. The second lever pusher 64 is fixedly mounted above the third gear 63 and is used to push the lever 43 to rotate. The fourth gear 62 is fixedly connected to the main shaft of the motor 61 and meshes with the third gear 63.

[0041] The third unlocking mechanism 6 drives the fourth gear 62 to rotate via the motor 61. The fourth gear 62 directly or indirectly meshes with the third gear 63. The fourth gear 62 drives the third gear 63 to rotate on the rotating shaft 42. The second lever pusher 64, which is fixedly installed above the third gear 63, pushes the lever 43 to rotate. The lever 43 pushes the latch mechanism 21 forward or backward to unlock or lock the glass door lock.

[0042] A fifth gear can be provided between the third gear 63 and the fourth gear 62. The fifth gear meshes with the third gear 63 and the fourth gear 62 respectively. The provision of the fifth gear can move the motor 61 away from the rotating shaft 42, and provide more space for the motor 61 in the inner lock body 2. At the same time, by changing the number of teeth of the fifth gear, the rotation speed of the third gear 63 can be changed, thereby changing the locking or unlocking speed.

[0043] The glass door lock can also be equipped with a control circuit board and touchscreen 11, please refer to [link / reference]. Figure 1 As shown, the touch screen 11 is mounted on the outer lock body 1. The control circuit board is electrically connected to the motor 61 and the touch screen 11 respectively. The user inputs the unlocking password through the touch screen 11. The processor on the circuit board compares the input unlocking password with the preset password of the processor. When the input unlocking password and the preset password of the processor match, the processor sends a signal to the motor 61. The motor 61 starts the main shaft to rotate, which drives the fourth gear 62 to rotate, thereby driving the third gear 63 to rotate on the rotating shaft 42. The second lever pusher 64, which is fixedly mounted above the third gear 63, pushes the lever 43 to rotate. The lever 43 pushes the lock tongue mechanism 21 forward or backward to unlock or lock the glass door lock.

[0044] The glass door lock can also be equipped with a fingerprint recognition mechanism 12, please refer to [link / reference]. Figure 1 As shown, the control circuit board is electrically connected to the motor 61 and the fingerprint recognition mechanism 12 respectively. The fingerprint recognition mechanism 12 is installed on the outer lock body 1. The user inputs the fingerprint to unlock through the fingerprint recognition mechanism 12. The processor on the circuit board compares the input fingerprint with the fingerprint preset by the processor. When the input fingerprint and the fingerprint preset by the processor match, the processor sends a signal to the motor 61. The motor 61 starts the main shaft to rotate, which drives the fourth gear 62 to rotate, thereby driving the third gear 63 to rotate on the rotating shaft 42. The second lever pusher 64, which is fixedly installed above the third gear 63, pushes the lever 43 to rotate. The lever 43 pushes the lock tongue mechanism 21 forward or backward to unlock or lock the glass door lock.

[0045] The processor can have multiple preset fingerprints. When the input fingerprint matches one of the preset fingerprints, the processor sends a signal to the motor 61.

[0046] The glass door lock can also be equipped with a facial recognition mechanism 13, please refer to [link / reference]. Figure 1 As shown, the face recognition mechanism 13 is installed on the outer lock body 1. Its working principle is similar to that of the fingerprint recognition mechanism 12 and the touch screen 11, and will not be described in detail here.

[0047] In one embodiment, a positioning part is provided on the lever 43, and a torsion spring is provided on the positioning part. The torsion spring is equivalent to a damper to prevent the lever 43 from rotating too fast. There is a pulling force when the lever 43 returns, making the unlocking process smoother.
