[0002] In places like government agencies, hospitals, and design institutes, to implement specific plans for urban and rural development and construction, it's common to store large quantities of local human resources documents for extended periods of time. These documents include, but are not limited to, census files and original documents of signed agreements with official seals. To preserve these documents over the long term, numerous cabinets are typically required for their classification, taking up significant space. To address this issue, compact cabinets have emerged, effectively reducing space requirements and facilitating access to relevant documents.

[0003] However, the lighting between existing dense cabinets is actually a relatively big problem. There is basically no lighting between the cabinets, and they rely entirely on the lighting provided by the venue. When the indoor environment is relatively dark, the user experience will be very poor. After searching for relevant content, it was found that there are patents that deal with the above problems, such as patent number CN213720726U, which has a lighting function. However, the existing technology is generally fixed lighting. In order to achieve a better lighting effect, a large number of lighting lamps are usually arranged.

The rotation sleeve 22 is symmetrically fixed to the first placement plate 16. The latch 23 is symmetrically fixed to the second placement plate 17. The latch 23 is connected to the rotation sleeve 22 for rotation. The rotation sleeve 22 and the latch 23 are hinged between the first placement plate 16 and the second placement plate 17. A locking assembly is provided in the fixed seat 32 to control When the second slide 49 is positioned within the first fixed seat 32 and the second upright 27 is manually controlled to approach the first upright 26, the angle between the first placement plate 16 and the second placement plate 17 becomes smaller. At this time, files and documents can be placed on the placement slot 18 and the second placement slot 21, which is very convenient. A large number of files and documents can be placed on the placement rack formed by the placement slot 18 and the second placement slot 21 (the bottoms of the placement slot 18 and the second placement slot 21 simultaneously support the documents), which facilitates batch operations by users.

[0034] See Figure 3 It should be noted that the second placement plate 17 and the first placement plate 16 are both slightly tilted outward to form a bulge in the initial state, ensuring that the movement trajectory of the second placement plate 17 is constant;

[0035] The locking assembly includes a socket 50 formed on the second slide 49, two movable grooves 51 formed in the first fixed seat 32, a slider 52 slidably disposed in the movable groove 51, a slider 31 passing through the movable groove 51 is fixed on the slider 52, and a spring 53 is fixed between the slider 52 and the inner wall of the movable groove 51, and one of the sliders 52 is inserted into the second slide 49;

[0036] See Figure 11 Both sides of the slide 2 49 are designed with inclined surfaces. When adjusting the position of the slide 2 49 , one of the pull heads 31 is manually pulled out to disengage the slider 52 from the socket 50 , and the slide 2 49 is manually pushed to move until the slider 52 is automatically locked into the other socket 50 .

[0037] A connecting strip 28 is fixed between the slide 1 48 and the slide 2 49, and a handle 54 is fixed on the connecting strip 28 for easy movement. A light strip 29 is fixedly installed on the back of the connecting strip 28, and lighting is provided by the light strip 29. When the connecting strip 28 moves with the fixing seat 1 32, it drives the light strip 29 to move, thereby providing mobile lighting, thereby achieving targeted lighting, improving the local lighting effect, and the overall structural design is also very simple. A battery box 55 is fixedly installed on the connecting strip 28, and a detachable battery is contained in the battery box 55 to power the light strip 29. The battery needs to be replaced regularly. A switch 56 is also fixedly installed on the connecting strip 28 to control the on and off of the light strip 29. The light strip 29, the battery box 55 and the switch 56 form a series circuit.

[0038] A magnet 1 34 is fixed on one side of the fixing seat 1 32 and the fixing seat 2 37 , and an iron block 33 adsorbed by the magnet 1 34 is fixed on the shelf 15 , and the free movement of the fixing seat 1 32 is restricted by the adsorption of the iron block 33 and the magnet 1 34 .

[0039] Two ends of a shielding cloth 45 are fixed to the second column 27 and the first column 26 respectively. In the initial state, the shielding cloth 45 is stretched straight. When storing certain documents that are easy to fall during movement, the documents can be placed directly behind the shielding cloth 45. The shielding cloth 45 plays a blocking role. After the second placement plate 17 and the first placement plate 16 are folded, the shielding cloth 45 will become loose and will not affect the placement of documents and files on the placement slot 18 and the second placement slot 21.

[0040] Directions:

[0041] When taking, placing, or checking documents and files, the corresponding hand wheel 13 is manually rotated. The hand wheel 13 drives the rotating shaft 1 43 to rotate. The sprocket 1 42 rotates along with the rotating shaft 1 43. The sprocket 1 42 drives the sprocket 2 40 to rotate through the chain 41. The sprocket 2 40 drives the rotating shaft 2 39 to rotate, thereby driving the track wheel 38 to move. The movement of the track wheel 38 on the track 14 drives the movement of the mobile cabinet 12 on the track 14, thereby revealing the corresponding shelf 15.

[0042] When there are few documents and files to be retrieved or checked, the switch 56 is manually turned on to power on the light strip 29, and the handle 54 is grasped to move the light strip 29 to help find the required documents and files.

[0043] When there are many files and documents to be taken in and put in / checked, the switch 56 is manually turned on to make the light strip 29 powered on and illuminated, and one of the pull heads 31 is manually pulled to make the slider 52 disengage from the socket 50, and the slide seat 2 49 is manually pushed to move until the slider 52 is automatically stuck in the other socket 50. At this time, the angle between the placement plate 1 16 and the placement plate 2 17 becomes smaller, and files and documents can be placed on the placement slot 18 and the placement slot 2 21, which is very convenient. A large number of files and documents can be placed on the placement rack formed by the placement slot 18 and the placement slot 2 21 (the placement slot 18 and the bottom of the placement slot 2 21 support the documents at the same time).

[0044] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand and implement the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made in accordance with the spirit of the present invention are intended to be covered by the scope of protection of the present invention.
