Background technique

When reading in the library or classroom, there are often people whispering, the reading environment is not good, it is easy to be influenced by the outside world, and the learning efficiency is low. Sometimes people listen to music to block out the noise, but they are still affected by other people's activities.

Contents of the invention

Design purpose: to avoid the deficiencies in the background technology, to design a quiet curtain with simple structure, easy to use and use.

Design scheme: in order to realize the above-mentioned purpose of the invention. The curtain is rolled in the cylinder by the shaft and connected with the disks on both sides of the cylinder through the shaft, and a coil spring is provided at one end, and the support rod is connected with the disk through the shaft, which is one of the technical characteristics of the utility model . The purpose of this is: when using the curtain, pull the crossbar at the bottom of the curtain to pull the curtain out, and fix it through the hook on the support rod, and then use it by absorbing it on the desktop through the suction cup. When not in use, put the crossbar Take it out from the hook, through the elastic potential energy of the coil spring, the curtain is automatically rolled into the cylinder, the two ends of the cross bar are fixed in the slots on the disc, and then the support rod is rotated and fixed in the slots of the disc, the overall volume Small, takes up little space for storage, and is easy to carry. 2. The bottom of the support rod is provided with a disc design, which is the second technical feature of the present invention. The purpose of doing this is: when in use, the curtain is adsorbed on the desktop through the disc, so that it will not fall over and cause damage to the desktop.

Technical solution: A quiet curtain, which is composed of a support rod, a cylinder and a curtain. The inside of the cylinder is a cavity and the surface of the cylinder is provided with grooves. The curtain is rolled into the cylinder and connected to the cylinder. The side disc is connected, one end of the shaft is provided with a coil spring, and the bottom of the curtain is provided with a cross bar, the support rod and the disc are connected through the shaft and the support rod is provided with a hook, the bottom is provided with a suction cup, and the disc is provided with several card slot. The length of the cross bar is greater than the distance between the two support bars. The length of the curtain is greater than the length between the hook and the top end of the support rod. There are at least three slots on each disc, and the positions of the slots correspond to the positions where the curtain is rolled into the rear cross bar and the support bar.

Compared with the background technology, the utility model has the following advantages: firstly, the structure is simple; secondly, it is convenient to use; thirdly, it can be folded and placed, which is convenient for storage and carrying; thirdly, it can block external interference and is practical.
