Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced otherwise than as specifically described herein, and thus the scope of the present invention is not limited by the specific embodiments disclosed below.
Referring to fig. 1, 2, 3 and 4, the invention relates to a hand-operated liftable closestool footrest, and a transmission mechanism of the invention is formed by combining chain transmission, bevel gear transmission and spiral transmission. When a person uses the mechanism, firstly, the rocking wheel 15 is manually rotated, the rocking wheel is designed into a large-diameter round wheel, the rocking wheel 15 and the driving chain wheel 16 are both mounted on the first shaft 17 through key connection, the first shaft 17 is mounted on the upper box 18 through the bearing 11, and the driving chain wheel 16 is axially positioned through the first sleeve 12 and the second sleeve 13. Rotation of the rocker 15 rotates the drive sprocket 16, which in turn is transmitted to the driven sprocket 22 via the chain 19.
Similarly, the driven sprocket 22 and the drive bevel gear 9 are also splined to the second shaft 21, so that the drive bevel gear 9 rotates together with the driven sprocket 22. The driven bevel gear 2 rotates in a vertical direction in a normal direction by the engagement of the bevel gears.
In this example, the height of the toilet bowl is 441mm, the height of the lower case is 260mm, and the maximum height of the pedal which can be lifted up by 180mm is 440 mm. For example, the pedal is only required to be lifted by 0-40mm by a common adult, and the optimal defecation angle can be basically realized;
in this example, the screw pitch is 2mm, the number of threads is 4, the thread has a coarse pitch, and the lead is 8mm, so that the screw rises to the maximum height, and the rocking wheel only needs to rotate 5 turns.
The driven bevel gear 2 and the nut sleeve 3 are connected in a welded mode, threads are arranged on the inner wall of the nut sleeve 3, the nut sleeve 3 rotates along with the driven bevel gear 2, the pedal 10 and the screw top cover 7 are connected through screws in a fixed mode, disassembly is convenient, and the screw top cover 7 and the screw 8 are connected in an interference fit mode. A round hole is formed in the upper box wall of the lower box body 23, the screw 8 extends out of the round hole, and the pedal 10 and the screw 8 are screwed out together with the rotation of the nut sleeve 3 to realize lifting movement. The round hole on the upper box wall of lower box 23 is less, only is used for stretching out screw 8, can effectively avoid water splash to in the box, shortens the life of part. The user can adjust the angle between the thigh and the upper body of the human body by putting the feet on the pedal and lifting the pedal, thereby achieving the most ideal defecation posture.
