The specific implementation manner of the utility model is as follows:

example 1: as shown in fig. 1-8, the present invention provides a rolling device, which is applied to a bookshelf of a learning desk, and comprises a rolling screen 1 and a fixed frame 2; the fixed frame 2 comprises a left side plate 3 and a right side plate 4 which are arranged at intervals, a storage space is arranged in the fixed frame 2, a window 5 communicated with the storage space is correspondingly arranged at the front end of the fixed frame, and articles are taken and placed in the storage space through the window 5; the inner side surfaces of the left and right side plates 3 and 4 are symmetrically provided with guide rails 6, and the two sides of the roller shutter 1 respectively slide along the guide rails 6 to open or close the window 5 of the roller shutter 1, so that the privacy of the fixed frame 2 is improved.

As shown in fig. 1-3, the fixed frame 2 further includes a back plate 10 connected to the rear ends of the left and right side plates 3, 4 and a storage box 11 located above the roller blind; the window 5 is formed at the front ends of the left and right side plates 3 and 4 and the storage box 11; the guide rails 6 comprise front vertical guide rails 7 which are positioned at the front ends of the left and right side plates 3 and 4 and close to the window 5, upper guide rails 8 which extend backwards along the upper ends of the front vertical guide rails 7, and rear vertical guide rails 9 which are positioned at the rear ends of the left and right side plates 3 and 4, and the front vertical guide rails 7 are communicated with the rear vertical guide rails 9 through the upper guide rails 8; the rear vertical guide rail 9 is positioned in front of the back plate 10, so that the roller shutter 1 and the back plate 10 do not interfere with each other in the sliding process of the roller shutter 1; then, the front vertical guide rail 7, the upper guide rail 8 and the rear vertical guide rail 9 form a sliding path of the roller shutter 1; the specific sliding mode is as follows: preceding vertical guide rail 7, upper guideway 8 and back vertical guide rail 9 on all be equipped with the spout, the both sides of roll up curtain 1 be located the spout respectively, just roll up curtain 1 for plastics or PVC material, make roll up curtain 1 and have glossy surface, can smoothly slide on guide rail 6.

In addition, the length of the front vertical guide rail 7 extends from the lower end of the storage box 11 to the bottom of the left and right side plates 3 and 4, so that the roller shutter 1 can close the window 5 after the roller shutter 1 is completely positioned in the front vertical guide rail 7; the length of the rear vertical guide rail 9 is shorter, and the rear vertical guide rail 9 is only formed on the upper half parts of the left and right side plates 3 and 4; when the roller blind 1 slides from the front vertical guide rail 7, passes through the upper guide rail 8 and enters the rear vertical guide rail 9, the roller blind 1 can open the window 5.

As shown in fig. 3, the roller shutter 1 comprises a plurality of shutter blades 12 hinged together end to end, each shutter blade 12 having two connecting ends, namely a shaft sleeve end 13 and a rotating shaft end 14; between two adjacent rolling shutter blades 12, a shaft sleeve end 13 on one rolling shutter blade 12 is sleeved on a rotating shaft end 14 on the other rolling shutter blade 12, so that the two rolling shutter blades 12 can be turned over, and the included angle between the two adjacent rolling shutter blades 12 ranges from 90 degrees to 180 degrees; when the roller shutter 1 slides on the guide rail 6, the roller shutter blades 12 can be folded and adjusted in angle according to the change of the position of the roller shutter 1. And when the window 5 is changed from the closed state to the open state, as shown in fig. 4, the rolling shutter blade at the lowest end of the front vertical guide rail 7 on the rolling shutter 1 is still in the front vertical guide rail 7, and a handle 15 is arranged on the outer surface of the rolling shutter blade 12, so that the handle 15 is always exposed outside, and then a person can conveniently operate the handle 15 to pull the rolling shutter 1 to slide.

As shown in fig. 4-8, the window 5 on the fixed frame 2 then has two states, open and closed by the roller shutter 1; in the open state, as shown in fig. 4 and 5, the roller shutter 1 is positioned on the upper guide rail 7 and the rear vertical guide rail 9; at this time, the rolling screen 1 has a tendency of sliding backwards under the action of the gravity of the rolling screen on the rear vertical guide rail 9, and the lower end of the rolling screen on the rear vertical guide rail 9 is abutted against the bottom of the rear vertical guide rail 9; so that the roller blind 1 stays in this position and the window 5 is opened. In a closed state, a handle 15 on a roller shutter blade 12 at the upper end of the front vertical guide rail 7 is pulled downwards, so that the roller shutter 1 slides out of the rear vertical guide rail 9, as shown in fig. 6 and 7, and the roller shutter 1 slides through the upper guide rail 8 and then enters the front vertical guide rail 7; when the rolling screen 1 slides to the state that the lower end of the rolling screen 1 is abutted against the bottoms of the left and right side plates 3 and 4, as shown in fig. 6, the window 5 is closed; when the window needs to be opened again, the handle 15 is pulled upwards to enable the roller shutter 1 to reversely reset and slide. The integral structure is simple, the sliding of the roller shutter 1 is easy and convenient, the window 5 on the fixed frame 2 can be closed or opened well through the roller shutter device, the privacy of the space is provided, the cost is low, and the popularization is high; as shown in fig. 8, the rolling shutter device is mounted on the bookshelf, so that the bookshelf has a private storage space, and the functions of the bookshelf are enriched.

Example 2: the present embodiment is different from embodiment 1 in that: the outer sleeve of the roller shutter 1 is provided with materials with moderate friction coefficient, such as rubber or nylon, so that when the roller shutter 1 slides along the guide rail 6, sliding friction force exists between the roller shutter and the guide rail.

Specifically, sliding friction force exists when the roller shutter 1 slides along the guide rail 6, so that a good damping hand feeling is achieved when the roller shutter 1 is pulled by a human hand; the roller shutter 1 can stay at any position of the guide rail 6, and the roller shutter 1 can slide only after force is applied to the roller shutter 1; this makes it possible for the roller shutter 1 not only to fully open the window 5 or to close the window 5; as shown in fig. 9, the roller blind 1 can also be left at the position after opening a part of the window 5, so that the roller blind 1 has more functions and is more diversified in use.
