[0021] 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.

[0022] Please see Figures 1-5 A simplified switch lock includes a lock cover, a combination lock 6, and a bolt 4. The lock cover includes a bottom cover 1 and a top cover 2. The top cover 2 is located above the bottom cover 1. A hinge frame 3 is provided at one end of the lower part of the lock cover. A cavity is provided inside the lock cover. A through hole is provided at the other end of the lock cover. The bolt 4 is slidably disposed in the cavity. One end of the bolt 4 is adapted to the through hole. A number of sets of inserts 5 are also provided at the other end of the bolt 4. A combination lock 6 that can abut against the number of sets of inserts 5 is also embedded in the cavity. The combination lock 6 is also provided with an unlocking groove adapted to the inserts 5.

[0023] The latch 4 engages with the combination lock 6 via several sets of inserts 5 at the other end. When the correct combination is not entered, the surface of the combination lock 6 abuts against the inserts 5, restricting the sliding of the latch 4 and thus locking it. The lock cover is connected to one end of the storage box via a hinge bracket. At this time, one end of the latch 4 extends out of the through hole of the lock cover and engages with the latch structure at the other end of the external storage box (such as the box body of the combination lock box), ensuring that the storage cavity is sealed.

[0024] Turn the dial of the combination lock 6. When the unlocking slot on the combination lock 6 is precisely aligned with the insertion block 5 of the bolt 4, the insertion block 5 is no longer blocked by the housing of the combination lock 6, the bolt 4 gains sliding space, and the unlocking preparation is complete.

[0025] The bottom cover 1 has a first support frame 7 on both sides above it, and the top cover 2 has a second support frame 8 adapted to the first support frame 7 below it. The latch 4 is located between the two sets of first support frames 7. The lock cover also has a switch for pushing the latch 4 to move. The switch includes a toggle block 9, a panel 10, a hinge shaft 11, and a push block 12. A groove adapted to the hinge shaft 11 is provided between the corresponding first support frame 7 and second support frame 8. An arc-shaped panel 10 is provided above the middle part of the hinge shaft 11. The top cover 2 has an unlocking hole adapted to the panel 10. The panel 10 has a toggle block 9 protruding from the unlocking hole. Push blocks 12 are symmetrically arranged on the left and right sides of the panel 10. The push blocks 12 are located on the hinge shaft 11. Baffles 13 are symmetrically arranged at the front and rear ends of the left and right sides of the latch 4. The push blocks 12 are located between the corresponding two sets of baffles 13.

[0026] The hinge shaft 11 of the switch is embedded in the grooves of the first support 7 and the second support 8, forming a stable rotation fulcrum. Moving the lever 9 protruding from the unlocking hole of the cover 2 causes the panel 10 and the hinge shaft 11 to rotate synchronously. The symmetrical push blocks 12 on the hinge shaft 11 rotate along with it. The push blocks 12 are located between the front and rear baffles 13 on both sides of the latch 4. When the lever 9 is rotated, the push blocks 12 directly press against the rear baffle 13 of the latch 4, generating a horizontal thrust. Guided by the two sets of first support 7 (to prevent slippage), the latch 4 slides smoothly towards the combination lock 6, and its protruding end gradually retracts into the cavity, disengaging from the external latch structure and completing the unlocking process.

[0027] After unlocking, open the storage box to retrieve items. After closing the box, reverse the lever 9. The pusher 12 presses against the front baffle 13 of the latch 4, pushing the latch 4 to slide towards the through hole until one end of the latch 4 protrudes out of the through hole and engages with the external locking mechanism. At this time, the unlocking slot of the combination lock 6 is misaligned with the insert 5, and the housing of the combination lock 6 again presses against the insert 5, restricting the sliding of the latch 4 and achieving locking.

[0028] In this embodiment, a prompting element is also provided on the latch 4. The prompting element includes a cylinder 14, a spring 15, and a steel ball 16. The lower part of the cylinder 14 passes through the latch 4, and a movable groove with a downward opening is also provided below the cylinder 14. The spring 15 and the steel ball 16 are disposed in the movable groove. The upper and lower sides of the spring 15 are connected to the top wall of the movable groove and the steel ball 16, respectively. Two arc-shaped grooves adapted to the steel ball 16 are also provided on the upper part of the bottom cover 1. During the sliding of the latch 4, the steel ball 16 of the prompting element always adheres to the surface of the bottom cover 1 under the elastic force of the spring 15. When the latch 4 slides to the "locked" position, the steel ball 16 is engaged in the first set of arc-shaped grooves of the bottom cover 1; when it slides to the "unlocked" position, the steel ball 16 is engaged in the second set of arc-shaped grooves. The tactile feedback and slight sound generated at the moment of engagement provide clear status feedback to the user, allowing them to determine whether the lock is in place without visual confirmation.

[0029] In this embodiment, the width of the part of the latch 4 near the combination lock 6 is greater than the width of the through hole, ensuring that the latch 4 is stably slidably connected to the lock cover.
