By setting the arc-shaped surfaces of the first shielding block 4, the second shielding block 5 and the third shielding block 6, the first shielding block 4, the second shielding block 5 and the third shielding block 6 can be easily moved.

[0032] The following is a detailed description of its overall specific settings and functions.

[0033] like Figure 1-Figure 7 As shown, the sides of the two first shielding blocks 4 are fixedly connected with connecting blocks 7, and the inner wall of the connecting block 7 is slidably connected with a fixing rod 8, and the fixing rod 8 is fixedly connected to the inner wall of the shielding box 3. By setting the fixing rod 8, the connecting block 7 can be connected to the shielding box 3, and the connecting block 7 sleeved on the surface of the fixing rod 8 can move, thereby ensuring that the first shielding block 4 can move. The surface of the fixing rod 8 is sleeved with a first spring 9, and the two ends of the first spring 9 are respectively fixedly connected to the connecting block 7 and the shielding box 3. By setting the first spring 9, the stable connection between the connecting block 7 and the shielding box 3 can be guaranteed, and the first spring 9 can limit the position of the connecting block 7. The side of the connecting block 7 close to the first spring 9 is fixedly connected with an "L"-shaped plate 10, and the inner wall of the "L"-shaped plate 10 is slidably connected with a moving rod 11. By setting the "L"-shaped plate 10, the moving rod 11 can be connected to the connecting block 7, and the moving rod 11 slidably connected to the inner wall of the "L"-shaped plate 10 can move.

[0034] The end of the moving rod 11 away from the connecting block 7 is fixedly connected with a circular plate 12, and the surface of the moving rod 11 is covered with a second spring 13, and the two ends of the second spring 13 are fixedly connected with the circular plate 12 and the "L"-shaped plate 10 respectively. By setting the circular plate 12, the second spring 13 can be conveniently installed, and by setting the second spring 13, the position of the moving rod 11 can be limited. The side of the second blocking block 5 close to the connecting block 7 is fixedly connected with the first moving block 14, and the side of the third blocking block 6 close to the connecting block 7 is fixedly connected with the second moving block 17. By setting the first moving block 14 and the second moving block 17, the second blocking block 5 and the third blocking block 6 can be conveniently connected to the connecting block 7. The first moving block 14 and the second moving block 17 are fixedly connected with the first slide bar 15 on the side away from each other, and the first slide bar 15 is slidably connected to the inner wall of the connecting block 7, and the side of the first moving block 14 close to the second moving block 17 is fixedly connected with the second slide bar 16, and the second slide bar 16 is slidably connected to the inner wall of the second moving block 17. By providing the first slide bar 15 and the second slide bar 16 , the first moving block 14 , the second moving block 17 and the connecting block 7 are connected while ensuring that the first moving block 14 and the second moving block 17 can move.

[0035] Working principle: when the lock body 1 needs to be opened, the key needs to be moved closer to the lock cylinder 2. In the process of moving the key closer to the lock cylinder 2, the key is inserted into the shielding box 3. When the key is close to the arc-shaped surfaces of the first shielding block 4, the second shielding block 5 and the third shielding block 6, the key pushes the first shielding block 4, the second shielding block 5 and the third shielding block 6 to move closer to the fixed rod 8. At this time, the connecting block 7 slides on the surface of the fixed rod 8, and the first spring 9 contracts, so that the key can be moved closer to the lock cylinder 2. Then, the lock body 1 can be opened by turning the key. When the key is moved away from the lock cylinder 2, under the action of the elastic force of the first spring 9, the first shielding block 4 moves away from the fixed rod 8. When the second shielding block 5 or the third shielding block 6 is moved alone, the first moving block 14 or the second moving block 17 pushes the moving rod 11 to slide on the inner wall of the "L"-shaped plate 10, so that the circular plate 12 moves away from the "L"-shaped plate 10. At this time, the lock hole of the lock cylinder 2 will not be completely exposed. When the second shielding block 5 or the third When the pressure of the blocking block 6 is applied, under the action of the elastic force of the second spring 13, the second blocking block 5 or the third blocking block 6 moves away from the "L"-shaped plate 10. By setting the first sliding bar 15 and the second sliding bar 16, the first blocking block 4, the second blocking block 5 and the third blocking block 6 can be moved separately while ensuring the connection between the first blocking block 4, the second blocking block 5 and the third blocking block 6. By setting the first blocking block 4, the second blocking block 5 and the third blocking block 6, the lock hole on the lock core 2 can be blocked, thereby preventing dust and other impurities from entering the lock hole as much as possible and affecting the normal use of the lock. By setting the first sliding bar 15 and the second sliding bar 16, the first blocking block 4, the second blocking block 5 and the third blocking block 6 can be moved separately while being connected. Therefore, when using a non-key to open the lock, the complexity of unlocking can be increased, thereby providing an anti-theft effect as much as possible.
