Embodiment Construction

[0008] The device is made of materials such as plexiglass or plastic. There are distance positioning screw holes 3 on the distance between the left and right arms from the mobile positioning bushing 1 and the distance from the arm to the mobile positioning shaft plate 2. After the distance is determined, they are connected with screws 8. There are screw holes 3 on the left and right arms distance moving positioning axle sleeve 1 two ends and restriction forearm cross-border baffle plate 4, after determining the angle, connect with bolt 9. Push-pull lock groove 10 is arranged on the lifting plate 6 that limits the upper body leaning forward to block the chest plate cover 5 and the limit upper body leaning forward to block the chest plate cover, after determining the height, connect with push-pull lock 11. Restrict upper body leaning forward to block chest plate cover 5 and clip 7 to have screw hole 3, connect with hinge 14. There are screw holes 3 on the inner side of the bott...

Abstract

The invention discloses a movable myopia-prevention and kyphosis-prevention device. The device is in a door shape, a shaft plate is sleeved with an arm movement positioning shaft sleeve, a threaded hole is formed in the arm movement positioning shaft sleeve, and after a distance is determined, a bolt is used for connecting the shaft plate with the arm movement positioning shaft sleeve. Threaded holes are formed in the two ends of the arm movement positioning shaft sleeve and a forearm border-crossing limit baffle, and after an angle is determined, bolts are used for connecting the arm movement positioning shaft sleeve with the forearm border-crossing limit baffle. Push-and-pull lock grooves are formed in a chest baffle sleeve and a lifting plate which is located in the chest baffle sleeve, and after a height is determined, a push-and-pull lock is used for connecting the chest baffle sleeve and the lifting plate. Threaded holes are formed in the chest baffle sleeve and a clamp, and a hinge is used for connecting the chest baffle sleeve and the clamp. Threaded holes are formed in the inner side of the bottom of a chest partition support and in the upper portion of the rear face of the clamp, and a hinge is used for connecting the chest partition support and the clamp. The clamp is used for clamping the arm movement positioning shaft sleeve and the shaft plate at the edge of a table. A shaft rod is sleeved with a chest-baffle-frame movement-distance positioning shaft sleeve, a threaded hole is formed in the chest-baffle-frame movement-distance positioning shaft sleeve, and a screw is used for connecting the shaft rod and the chest-baffle-frame movement-distance positioning shaft sleeve. Threaded holes are formed in the left and right corners of the upper end of the lifting plate in the chest baffle sleeve and in the chest-baffle-frame movement-distance positioning shaft sleeve, and after positioning is conducted, bolts are used for connected the chest baffle sleeve and the chest-baffle-frame movement-distance positioning shaft sleeve. Threaded holes are formed in chest-baffle-frame leg shaft sleeves and leg shaft rods, and after positioning is conducted, screws are used for connecting the chest-baffle-frame leg shaft sleeves and the leg shaft rods. The clamp is used for fixing the chest-baffle-frame leg shaft sleeves to rails on table legs.

Description

technical field [0001] The invention relates to a device capable of preventing people from suffering from myopia and hunchback. Background technique [0002] There are many students nowadays, their postures are very incorrect when reading and writing, which causes their eyes to become short-sighted, and their spines are deformed into hunchbacks. In this way, the healthy development of students has been greatly affected. Contents of the invention [0003] The purpose of the present invention is to improve a mobile anti-myopia anti-hunchback device that can maintain correct posture when students are studying. [0004] The purpose of the present invention is achieved in this way: the device moves the positioning shaft sleeve by the distance of the left and right arms, moves the positioning shaft plate from the arm distance, limits the forearm cross-border baffle plate, restricts the upper body to lean forward to block the chest plate sleeve, and restricts the upper body to l...
