Positioning rods 1101 that respectively cooperate with the positioning sleeves 1102 are fixedly arranged on both sides of the lock head 4. In the process of the lock box 1 and the lock head 4 cooperating, it is only necessary to insert the positioning rods 1101 on both sides of the lock head 4 into the positioning sleeves 1102 on both sides of the lock box 1, so that the lock head 4 and the lock box 1 can be accurately engaged. In coordination, a plurality of lock cylinders 2 are vertically arranged on the inner side of the lock box 1. In this embodiment, three lock cylinders 2 are arranged. The specific number can be adjusted according to actual conditions. The more lock cylinders 2 are, the higher the anti-theft function of the turnover box 14 is. A first mark plate 201 is fixedly arranged on the top of the lock cylinder 2. The first mark plate 201 can adopt a color plate that is easy to observe. For example, the first mark plate 201 can adopt yellow or red. A first scale plate 202 that cooperates with the first mark plate 201 is fixedly arranged on the front side of the lock box 1. The first scale plate 202 is made of a transparent material, and scale lines are arranged on the first scale plate 202. The two ends of the three lock cylinders 2 are respectively provided with a first adjustment mechanism 3 located on the inner side of the lock box 1. The first adjustment mechanism 3 includes a first screw rod 301 vertically fixedly arranged on the inner side of the lock box 1.A connecting plate 303 slidably sleeved on the first screw rod 301 is fixedly provided on both sides of the lock cylinder 2, and a first knob 302 is threadedly sleeved on the first screw rod 301 and fits with the lower side of the connecting plate 303. A first operating slot 305 matching with the first knob 302 is provided on the front side of the lock box 1, and one side of the first knob 302 extends out of the front side of the lock box 1 through the first operating slot 305. A compression spring 304 sleeved on the outer side of the first screw rod 301 is fixedly provided on the upper side of the connecting plate 303, and one end of the compression spring 304 is fixedly connected to the lock box 1. When it is necessary to adjust the initial position of the lock cylinder 2, it is only necessary to rotate the first knob 302 to make the first knob 302 spirally rise and fall on the first screw rod 301, thereby pushing the connecting plate 303 on the upper side of the first knob 302 to rise and fall, so that the lock cylinder 2 on one side of the connecting plate 303 rises and falls, and the initial position of the lock cylinder 2 can be adjusted.

[0036] like Figure 1 , Figure 2 , Figure 3 , Fig.11 As shown, a trigger mechanism 13 is provided on the inner side of the three lock cylinders 2, and the trigger mechanism 13 includes a trigger rod 1301 which slides vertically through the bottom of the lock cylinder 2, and the lower end of the trigger rod 1301 slides through the lower side of the lock box 1 and extends to the inner side of the lock shell 7, and the upper end of the trigger rod 1301 is fixedly provided with a trigger magnet 1303 which is slidably connected to the inner side of the lock cylinder 2. In order to increase the suction force, the trigger magnet 1303 can be a rubidium magnet, and the lower side of the trigger magnet 1303 is fixedly provided with a reset spring 1302 which is sleeved on the outer side of the trigger rod 1301 and fixedly connected to the bottom of the lock cylinder 2. When in use, when the trigger magnet 1303 is raised or lowered, the trigger rod 1301 is driven to slide vertically at the bottom of the lock cylinder 2, thereby causing the reset spring 1302 to elastically deform.

[0037] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig.12 , Fig.13As shown, three second adjustment mechanisms 6 are provided on the inner side of the lock head 4, which respectively pull the three trigger mechanisms 13 for vertical height adjustment. The second adjustment mechanism 6 includes a reset cylinder 5 that vertically slides through the upper side of the lock head 4. The front side thread of the lock head 4 is penetrated by a positioning knob 610 that abuts against the outer side of the reset cylinder 5. Before the lock head 4 is used, the positioning knob 610 is in a relaxed state (that is, one end of the positioning knob 610 does not abut against the outer side of the reset cylinder 5). Before turning the second knob 602, the positioning knob 610 is first turned so that one end of the positioning knob 610 abuts against the outer side of the reset cylinder 5, so that the reset cylinder 5 is positioned to prevent the reset cylinder 5 from shaking. Sliding sleeves 607 are fixedly provided on both sides of the reset cylinder 5, and the inner sides of the two sliding sleeves 607 are slidably provided with a sleeve that abuts against the lock The guide rod 608 is fixedly connected to the inner side of the head 4, and the second screw rod 601 is vertically slidably penetrated at the bottom of the reset cylinder 5. The second knob 602 which is threadedly sleeved on the outer side of the second screw rod 601 is rotatably provided at the bottom of the reset cylinder 5. The front side of the lock head 4 is provided with a second operating groove 605 which cooperates with the second knob 602. The lower end of the second screw rod 601 is fixedly provided with an attraction magnet 606 which magnetically cooperates with the trigger magnet 1303. In order to improve the attraction of the attraction magnet 606 to the trigger magnet 1303, the attraction magnet 606 adopts a rubidium magnet. The bottom of the lock head 4 is provided with a second through hole 604 which cooperates with the second screw rod 601, and the top of the lock box 1 is provided with a first through hole 101 which cooperates with the second through hole 604. When in use, the lower end of the second screw rod 601 is penetrated in sequence. The second screw rod 601 extends through the second through hole 604 and the first through hole 101 to the interior of the lock box 1, so that the attraction magnet 606 at the lower end of the second screw rod 601 is inserted into the interior of the lock box 1. When in use, when the positioning rods 1101 on both sides of the lock head 4 are inserted into the positioning sleeves 1102 on both sides of the lock box 1, the three second screw rods 601 extending from the lower side of the lock head 4 and the attraction magnet 606 at the lower end thereof can be inserted into the interior of the lock cylinder 2 through the first through hole 101, so that the attraction magnet 606 is attracted to the trigger magnet 1303 inside the lock cylinder 2, and the positioning knob 610 is tightened, and then the second knob 602 is turned, so that the second screw rod 601 can be driven to rise and fall on the inner side of the reset cylinder 5. When the second knob 602 is rotated and drives the second screw rod 601 to rise, it will pull the second screw rod 60 The attraction magnet 606 at the lower end of 1 is raised. Since the attraction magnet 606 and the trigger magnet 1303 are always in an attraction state, the raising of the attraction magnet 606 will drive the trigger magnet 1303 to rise. The upper end of the second screw rod 601 is fixedly provided with a second mark plate 603 which is slidably connected to the inner side of the reset cylinder 5. The second mark plate 603 can adopt a color plate that is easy to observe. For example, the second mark plate 603 can adopt yellow or red. A second scale plate 609 matched with the second mark plate 603 is fixedly provided on one side of the reset cylinder 5. The second scale plate 609 is made of transparent material, and scale lines are arranged on the second scale plate 609, so that personnel can observe the position of the second mark plate 603 through the second scale plate 609, and the position of the second mark plate 603 can be accurately adjusted.Improve the efficiency of unlocking.

[0038] like Figure 1 , Figure 2 , Figure 8 , Fig.10 As shown, the lower ends of the three trigger mechanisms 13 are all provided with a lock core mechanism 9 that cooperates with the lock rod 8. The lock core mechanism 9 includes a lock core rod 901 fixedly arranged at the lower end of the trigger rod 1301 and located on the inner side of the lock shell 7. A first lock core groove 902 is opened at the bottom of one side of the lock core rod 901, and a second lock core groove 903 that cooperates with the first lock core groove 902 is opened on one side of the lock rod 8. When in the locked state, the first lock core groove 902 on the lock core rod 901 is located below the second lock core groove 903, and the distance between the first lock core groove 902 and the second lock core groove 903 can be adjusted, for example, the initial distance between the first lock core groove 902 and the second lock core groove 903 is controlled to be 5-10cm, and the accuracy between the first lock core groove 902 and the second lock core groove 903 is 1mm, for example, for different lock boxes 1 and lock shells 7 (i.e. lock boxes 1 and lock shells 7 of different batches), the initial distance between the first lock core groove 902 and the second lock core groove 903 can be 5, 6, 7, 8, 9 or 10 cm. When the first lock core groove 902 and the second lock core groove 903 are at the initial distance, the first knob 302 is at the bottom of the first operating groove 305. When in use, when the first lock core groove 902 on the three lock core rods 901 coincide with the second lock core groove 903 on the locking rod 8, the pull ring 1204 can be pulled to drive the pull rod 1203 to slide out from the inner side of the lock shell 7, so that the pull plate 1201 at one end of the pull rod 1203 drives the locking rod 8 to slide on the inner side of the lock shell 7, which can drive the first lock buckle 10 at one end of the locking rod 8 to slide, so that the first lock buckle 10 is engaged with the second lock buckle 18 at one end of the turnover box 14 to complete the locking.

[0039] It should be noted that, when using this box-type anti-theft device, the first knob 302 is first turned, so that the first knob 302 can be spirally lifted and lowered on the first screw rod 301, and then the connecting plate 303 on the upper side of the first knob 302 is pushed up and down, so that the lock cylinder 2 on one side of the connecting plate 303 is lifted and lowered, and the initial position of the lock cylinder 2 can be adjusted, that is, the lock cylinder 2 drives the trigger rod 1301 and the lock core rod 901 on its lower side to rise to a specific position, for example, the lock core rod 901 is raised by 1.2 cm, and then the lock head 4 is slid into the inner side of the groove 16 at one end of the turnover box 14, so that the positioning rods 1101 on both sides of the lock head 4 can be inserted into the positioning sleeves 1102 on both sides of the lock box 1, and at the same time, The lower end of the second screw rod 601 passes through the second through hole 604 and the first through hole 101 in sequence and extends to the interior of the lock box 1, so that the attraction magnet 606 at the lower end of the second screw rod 601 is inserted into the interior of the lock cylinder 2 inside the lock box 1, so that the attraction magnet 606 is attracted to the trigger magnet 1303 inside the lock cylinder 2. During the process of attraction between the attraction magnet 606 and the trigger magnet 1303, the elastic force of the reset spring 1302 pushes the trigger magnet 1303 to always be in the initial position, that is, the trigger magnet 1303 pushes the attraction magnet 606 to rise, so that the second screw rod 601 rises, and the reset cylinder 5 is driven by the second knob 602 to slide and rise on the upper side of the lock head 4, and the rising height is also 1.2cm, then by turning the positioning knob 610, one end of the positioning knob 610 is abutted against the outer side of the reset cylinder 5, so that the reset cylinder 5 is positioned, and then the second knob 602 is turned to drive the second screw rod 601 to rise, which will pull the attraction magnet 606 at the lower end of the second screw rod 601 to rise. Since the attraction magnet 606 and the trigger magnet 1303 are always in an attracted state, the rise of the attraction magnet 606 will drive the trigger magnet 1303 to rise. The trigger magnet 1303 pulls the trigger rod 1301 to slide vertically at the bottom of the lock cylinder 2, thereby causing the reset spring 1302 to deform elastically, and at the same time, the lock core rod 901 at the lower end of the trigger rod 1301 is vertically raised on the inner side of the lock shell 7, so that the first lock core rod 901 on one side of the lock core rod 901 is lifted. The groove 902 is raised to a certain height so that the first lock core groove 902 coincides with the second lock core groove 903 on the lock rod 8, so that one of the lock core rods 901 can be unlocked from the lock rod 8. Similarly, by unlocking the remaining lock core rods 901 from the lock rod 8, the lock rod 8 can be unlocked, so that the lock rod 8 is pushed by the elastic force of the tensioning spring 1202, so that the first lock buckle 10 at one end of the lock rod 8 is disengaged from the second lock buckle 18 at one end of the turnover box 14, so that one end of the inner core 15 can be unlocked from one end of the turnover box 14, and the inner core 15 can slide out of the turnover box 14 freely; the rising distance of the above-mentioned lock core rod 901 (that is, the rising and moving distance of the first lock core groove 902) is determined according to two aspects, one of which is the first mark plate 201, and the second is the lifting distance of the second mark plate 603. For example, the initial distance between the first lock core groove 902 and the second lock core groove 903 is 5 cm. By rotating the first knob 302, the first knob 302 can be rotated to make the first knob 302 spirally rise on the first screw rod 301, thereby pushing the connecting plate 303 on the upper side of the first knob 302 to rise, so that the lock cylinder 2 on one side of the connecting plate 303 can be raised, and the initial position of the first mark plate 201 at the upper end of the lock cylinder 2 can be adjusted. The moving distance of the first knob 302 in the first operating groove 305 is limited, and the maximum lifting distance of the first knob 302 can be set to 2 cm (that is, the vertical height of the first operating groove 305 is 2 cm), and the second operating groove 60 The vertical height of the second operating groove 605 is 2 cm, and the maximum distance that the second mark plate 603 moves in the reset cylinder 5 is set to 3 cm, that is, the sum of the vertical height of the second operating groove 605 and the maximum distance that the second mark plate 603 moves in the reset cylinder 5 is the initial distance between the first lock cylinder groove 902 and the second lock cylinder groove 903. Therefore, after the first knob 302 is raised by a certain distance, the second knob 602 is also required to drive the second screw rod 601 to rise by a certain distance, so that the first lock cylinder groove 902 can be raised by 5 cm together, that is, the first lock cylinder groove 902 and the second lock cylinder groove 903 are overlapped, and the lock is unlocked. The specific operation is: adjust the initial position of the first mark plate 201 to 1.2 cm, and when the lock cylinder 2 is raised, it will drive the lock cylinder rod 901 to rise from the initial position by 1.2cm, then turn the second knob 602 to raise the second screw rod 601, and then adjust the height of the second mark plate 603 at the upper end of the second screw rod 601, so that the height of the second mark plate 603 is adjusted to 3.8cm. By adjusting the double distance between the first mark plate 201 and the second mark plate 603, the anti-theft effect is further improved. By analogy, the height of the three second mark plates 603 can be adjusted, and the height adjustment of each second mark plate 603 can be different, thereby improving the anti-theft performance of the turnover box 14. .
