DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] The present application embodiment provides a microcomputer password disc brake lock, such as Figure 1-Figure 2 As shown, it includes a lock disk 1, a lock tongue 2, an electromagnetic coil 4, an operating keyboard 6, a microcomputer 601, etc.

[0023] Specifically, a card slot 101 is provided at the bottom of one end of the lock disk 1 along the length direction, and a first cavity 102 and a second cavity 103 are provided in the lock disk 1 from one end to the other end; the lock tongue 2 is vertically arranged in the first cavity 102, and a protrusion is provided on the top of the lock tongue 2, and a first groove 201 is provided on the side of the protrusion facing the second cavity 103, and the top of the protrusion is connected to a locking handle 3, and the locking handle 3 passes through the lock disk 1 from the top of the lock disk 1; the electromagnetic coils 4 are a pair, which are arranged at intervals in the length direction of the lock tongue 2, and a locking clamp 5 is provided between the electromagnetic coils 4. When the bottom of the lock tongue 2 abuts against the lock disk 1, the locking clamp 5 has the same height as the first groove 201, and the first cavity 102 and the second cavity 103 are A first through hole is provided on the wall of the lock disk 1 between the two sides, for the locking latch 5 to penetrate into the first cavity 102, and a first spring 501 is sleeved on the end of the locking latch 5 away from the first groove 201, one end of the first spring 501 is fixed to the electromagnetic coil 4, and the other end is fixed to the locking latch 5. When the locking latch 5 is separated from the first groove 201, the first spring 501 is in a stretched state; an operating keyboard 6 is provided on the lock disk 1, which is electrically connected to a microcomputer 601, and the microcomputer 601 is provided in the second cavity 103. The microcomputer 601 is electrically connected to the electromagnet, and when a locking signal is input through the operating keyboard 6, the microcomputer 601 controls the electromagnet to open, and the electromagnet absorbs the locking latch 5 to separate from the first groove 201.

[0024] During actual use, when the lock needs to be closed, the locking latch 5 is first controlled to retract. Specifically, the locking latch 5 can be retracted by turning on the electromagnetic coil 4, or the top of the locking latch 5 facing the first groove 201 can be set as an inclined surface 503. During the downward movement of the lock tongue 2, the locking latch 5 is pushed to retract by the inclined surface 503, and then the locking handle 3 is pressed to make the bottom of the lock tongue 2 abut against the lock disk 1. At this time, the electromagnetic coil 4 is controlled to be closed, and the first spring 501 in a stretched state will pull the locking latch 5 into the first groove 201 to lock the lock tongue 2.

[0025] Preferably, see Figure 1 , Figure 2The end of the locking clamp 5 facing the first groove 201 is sleeved with a retaining ring 502. When the retaining ring 502 abuts against the wall between the first cavity 102 and the second cavity 103, the lock tongue 2 is completely inserted into the first groove 201. The setting of the retaining ring 502 can prevent the lock tongue 2 from being excessively extended by the elastic force of the first spring 501, and the lock tongue 2 is pushed for a long time, causing the lock tongue 2 to tilt and be stuck when unlocking and difficult to reset.

[0026] For details, see Figure 1 The second spring 7 is provided at the bottom of the first cavity 102, and the second spring 7 is sleeved outside the lock tongue 2. The top of the second spring 7 is connected to the lock tongue 2, and the second spring 7 is located below the first groove 201. When the lock tongue 2 is fully inserted into the second spring 7 and is located in the slot 101, the second spring 7 is in a compressed state. When the electromagnetic coil 4 is turned on, the locking clamp 5 is retracted, and the second spring 7 pushes the lock tongue 2 to retract, and the lock is opened, and there is no need to manually pull the locking handle 3 to unlock.

[0027] Specifically, a second through hole is formed on the top of the lock plate 1, and the locking handle 3 passes through the second through hole into the first cavity 102. The width of the top of the lock tongue 2 is greater than the diameter of the second through hole, so as to prevent the lock tongue 2 from being pulled out of the second through hole. Figure 1 A second groove 104 corresponding to the bottom of the lock tongue 2 is formed on the wall of the lock disk 1 below the card slot 101. After the lock tongue 2 is inserted downward into the second groove 104, the stability of the lock tongue 2 can be improved.

[0028] The above are only some of the embodiments listed in this application and are not intended to limit this application.
