The four three-color lights 21 are fixedly mounted on the four corners of the top of the shelf body 1, and the alarm device 2 is fixedly mounted on the four corners of the bottom load plate of the shelf body 1.
[0017] The alarm device 2 consists of a top plate 3, a bottom plate 4, a telescopic rod 5, a first spring 6, a first screw sleeve 7, a second screw sleeve 8, a sleeve 9, a connecting rod 10, a bolt 13, a touch rod 14, a metal touch ring 16, a second spring 17 and a control module. The two ends of the telescopic rod 5 are fixedly connected to the top plate 3 and the bottom plate 4 respectively. The first spring 6 is sleeved on the telescopic rod 5. The upper and lower ends of the first spring 6 act on the top plate 3 and the bottom plate 4 respectively. The first screw sleeve 7 is fixedly mounted on the bottom plate 4. The second screw sleeve 8 is screwed and fixed in the first screw sleeve 7. The sleeve 9 is screwed and fixed in the second screw sleeve 8. The connecting rod 10 is fixedly mounted on the top plate 3, and the connecting rod 10 is slidably mounted in the sleeve 9. Three metal touch rings 16 are fixedly sleeved on the connecting rod 10. An insulating collar 23 is provided between the metal touch rings 16. A countersunk hole 22 is provided on the sleeve 9. The outer end of the countersunk hole 22 is set as a threaded hole structure. The sleeve 9 A groove 20 communicating with the countersunk hole 22 is also provided on it. The bolt 13 is screwed into the threaded hole structure of the countersunk hole 22. The touch rod 14 is slidably installed in the countersunk hole 22. The second spring 17 is installed in the countersunk hole 22.
