Description

Technical Field

[0001] This utility model relates to the field of furniture lock technology, specifically a furniture lock. Background Technology

[0002] Furniture locks are locks installed on various types of furniture to protect the items inside. They are commonly used in wardrobes, chests of drawers, glass cabinets, office desk drawers, and various chests, cabinets, and bags to ensure that items cannot be accessed by unauthorized persons. Furniture locks come in a variety of types, and can be divided into different categories according to their construction and function, such as pin tumbler locks and leaf locks, as well as locks with different latch shapes, such as square latches, beveled latches, and crab claw-shaped latches.

[0003] Although existing furniture locks can usually only automatically close and open, the internal sensing components of traditional electronic locks are relatively complex. Therefore, if the furniture lock is damaged, it requires professional repair. In addition, the complex structure results in a long response time when locking, which increases the waiting time for users. Furthermore, it consumes a lot of power and requires frequent replacement of batteries and other power supply devices. Some furniture locks only have smart locking, so they cannot be opened when there is a problem. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a furniture lock, including a lock box 1 and a lock base 2. A fixing plate 6 is fixedly installed at the bottom of the lock box 1. A control component 5 is provided on the surface of the lock box 1, and an electrically controlled telescopic component 7 is fixedly connected to the edge of the surface of the fixing plate 6. A swing cover 8 is provided in the inner cavity of the lock box 1, and a locking component 13 is snapped into the bottom of the swing cover 8. A swing component 11 is provided between the locking component 13 and the swing cover 8. A spring 12 is provided between the locking component 13 and the inner cavity of the lock box 1. A key 4 is movably inserted into the surface of the lock box 1, and one end of the key 4 abuts against the swing component 11. One end of the electrically controlled telescopic component 7 is inserted into the port of the swing component 11. A connecting plate 9 is slidably sleeved on the surface of the lock box 1. The inner cavity of the lock box 1 has an installation groove for the swing cover 8 and the locking component 13, which can control the swing cover 8 and the swing component 11. The moving part 11 and the locking part 13 rotate. The locking part 13 has an inner cavity for installing the spring 12. One end of the spring 12 abuts against the inner wall of the lock box 1, and the other end contacts the swinging part 11. When the key 4 is inserted into the inner cavity of the lock box 1 and contacts the end of the swinging part 11, the key 4 is rotated so that one end of the key 4 presses the swinging part 11 to rotate, causing the swinging part 11 to press the spring 12. At the same time, the swinging cover 8 and the locking part 13 also rotate the swinging part 11. The port of the swinging part 11 presses the electrically controlled telescopic part 7, causing the telescopic end of the electrically controlled telescopic part 7 to retract. After the fastening force is lost, the bottom of the locking part 13 slides on the connecting plate 9, thereby driving the connecting plate 9 to move. The connecting plate 9 then drives the lock tongue 10 to retract from the lock seat 2, and the lock can be opened.

[0022] Mounting plate 3 is fixedly installed on the bottom of fixing plate 6 and lock seat 2. Lock box 1 and lock seat 2 are installed on the door and cabinet respectively through mounting plate 3 and are aligned with each other.

[0023] A latch 10 is fixedly connected to the surface of the connecting plate 9, and one end of the latch 10 is inserted into the inner cavity of the lock seat 2. The latch 10 has rotatable angles on both sides, and a retaining spring is installed between the rotatable angles and the inner cavity of the latch 10. This retaining spring automatically resets the latch 10 when the control component 5 is opened. For details, please refer to [link / reference]. Figure 5 .

[0024] Please see Figure 6The control component 5 includes a housing 51, which is rotatably fitted onto the top of the lock box 1, and its bottom is inserted into the surface of the swing cover 8. A keypad 52 is provided on the surface of the housing 51, and a circuit board 53 is provided at the bottom of the keypad 52. A battery 54 is also provided at the bottom of the circuit board 53. The circuit board 53, battery 54, and keypad 52 are electrically connected to each other. The output terminal of the circuit board 53 is electrically connected to the input terminal of the electronically controlled telescopic component 7. The battery 54 provides power to the circuit board 53. The keypad 52 has numeric buttons and an confirmation button. Passwords are entered using the numeric buttons, and then confirmed by pressing the confirmation button. Circuit board 53 receives and confirms the information, then controls the extended end of the electrically controlled telescopic component 7 to retract from the port of the swing component 11, thus removing its obstruction of the swing component 11. The locking spring inside the latch 10 then automatically rebounds, causing the latch 10 to retract from the lock seat 2. This also resets the swing cover 8, the swing component 11, and the locking piece 13. Simultaneously, the swing cover 8 rotates the outer casing 51. When closing is required, rotating the outer casing 51 causes the swing cover 8, the swing component 11, and the locking piece 13 to rotate, causing the connecting plate 9 to insert the latch 10 into the lock seat 2. Finally, the electrically controlled telescopic component 7 is inserted into the port of the swing component 11. (See also...) Figure 5 In addition, circuit board 53 is fixed to the surface of 1 by a mounting bracket and will not rotate with 51.

[0025] During operation or use, first install the lock box 1 and lock seat 2 onto the door and cabinet respectively using the mounting plate 3, aligning them. Enter the password using the numeric keypad, then press the confirmation key. The circuit board 53 receives and confirms the information, then controls the extended end of the electronically controlled telescopic component 7 to retract from the port of the swing component 11, losing its obstruction to the swing component 11. The locking spring inside the bolt 10 then automatically rebounds, causing the bolt 10 to retract from the lock seat 2. This also resets the swing cover 8, the swing component 11, and the locking piece 13. If the control component 5 malfunctions, insert the key 4 into the inner cavity of the lock box 1, contacting the extended end of the swing component 11, and rotate it. Key 4 causes one end of key 4 to press and rotate the swing member 11, which in turn compresses the spring 12. At the same time, the swing cover 8 and the locking member 13 also rotate the swing member 11. The port of the swing member 11 presses the electrically controlled telescopic member 7, causing the telescopic end of the electrically controlled telescopic member 7 to retract. After losing the fastening force, the bottom of the locking member 13 slides on the connecting plate 9, thereby driving the connecting plate 9 to move. The connecting plate 9 then drives and drives the lock tongue 10 to retract from the lock seat 2, thus opening the lock. The control component 5 has a simple structure, which is easy to repair after a problem occurs. The telescopic member 7 alone makes the lock fast to close. The structure is also simple and energy-saving. Finally, it can also be opened by key 4.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
