Detailed Description
The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Examples, see fig. 1-4: a neck support for preventing myopia comprises a cylinder body 1, a telescopic column 2 and a fixing device. The side wall of the cylinder body 1 is provided with an axial sliding groove 3. The upper end part of the telescopic column 2 is provided with a jaw support 4, and the jaw support 4 is a three-dimensional cartoon-shaped jaw support and comprises three-dimensional cartoon-shaped jaw supports such as piglets, bears, elephants, kittens, puppies and the like, so that the myopia-preventing neck support is more attractive and popular with students; the telescopic column 2 is arranged in the inner barrel cavity of the barrel body 1 in a matched manner and can slide up and down along the inner barrel cavity, the lower end of the telescopic column 2 and the sliding groove 3 are provided with limiting devices, and the limiting devices are used for adjusting the distance of the telescopic column 2 sliding up or down in the inner barrel cavity of the barrel body 1. The fixing device is used for installing and fixing the myopia-preventing neck support on the edge of a desk board or other board surfaces.
Specifically, the fixing device comprises a lower clamp plate 5, a screw rod 6 and an upper clamp plate 7 fixed at the lower end of the barrel 1, wherein a handle part 8 is arranged at the lower end of the screw rod 6, a through hole matched with the screw rod 6 is formed in the lower clamp plate 5, a guide post 9 is arranged on the upper side surface of the lower clamp plate 5 at the rear side of the through hole, an internal thread matched with the screw rod 6 is arranged in an inner barrel cavity at the lower end of the barrel 1, and a guide groove 10 matched with the guide post 9 is formed in the side wall at the lower end of the barrel 1; the screw 6, the lower clamping plate 5 and the lower end of the barrel 1 are connected in a matching way. The lower side surface of the upper clamping plate 7 and the upper side surface of the lower clamping plate 5 are respectively provided with a flexible layer 11.
The screw rod 6, the lower clamping plate 5 and the lower end of the barrel 1 are connected in a matched mode, wherein the screw rod 6 is inserted into a through hole of the lower clamping plate 5 in a matched mode, the screw rod 6 is in threaded connection with the lower end of the barrel 1, and the guide column 9 is inserted into the guide groove 10 in a matched mode. The screw 6 is rotated by operating the handle part 8, so that the screw 6 pushes the lower splint 5 to move upwards or downwards, thereby achieving the purpose of installing and fixing the myopia-preventing neck brace, and the installation and the operation are simple and the installation is firm. The flexible layer 11 can be a rubber pad or a foam material pad, so that the friction force between the flexible layer and a desk board or other board surfaces is increased, and the myopia-preventing neck support is more stably installed. The cooperation of guide post 9 and guide way 10 makes lower plate 5 more stable, improves the centre gripping dynamics of upper plate 7 and lower plate 5.
