    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • The present invention will be specifically described as below by specific embodiments.
    • Embodiment 1:
  • As illustrated in Figs. 1-8, a baby walker with an infinite-adjustment function is provided, like a conventional baby walker, including an upper plate 1 and a lower plate 2, a backrest 3 being provided on the upper plate 1, a wheel set 4 being provided on the lower plate 2. The upper plate 1 is connected to the lower plate 2 by a telescopic structure 5 capable of adjusting a space between the upper plate 1 and the lower plate 2.
  • The telescopic structure 5 includes a fixed seat 501 and a movable arm 502. The fixed seat 501 is in telescopic connection to the movable arm 502. In this embodiment, the upper end of the fixed seat 501 is provided with an opening. The end of the movable arm 502 connected to the fixed seat 501 is fitted with the opening. The end of the movable arm 502 connected to the fixed seat 501 is inserted into a chamber of the fixed seat 501 through the opening. The chamber 503 is fitted in size with the end of the movable arm 502 connected to the fixed seat 501.
  • The fixed seat 501 is fixed on the lower plate 2, and the movable arm 502 is connected to the upper plate 1. The fixed seat 501 is integrated with the lower plate 2. In this embodiment, the fixed seat 501 is a plastic shell.
  • In this embodiment, an upper coil pipe 6 is provided in the upper plate 1 and secured with the upper plate. A lower coil pipe 8 is provided in the lower plate 2 and secured with the lower plate. A support pipe 7 is provided in the movable arm 502. A V-shaped spring piece 701 is disposed in the support pipe 7. The upper coil pipe 6 is fixedly connected to the upper end of the support pipe 7. The lower end of the support pipe 7 is in telescopic connection to a bent portion 801 of the lower coil pipe 8. The lower end of the support pipe 7 may also be inserted into the bent portion 801 of the lower coil pipe 8. The bent portion 801 of the lower coil pipe 8 is located in the fixed seat 501.
  • The movable arm 501 includes an outer support cover 503 and an inner support cover 504. The inner support cover 504 is sheathed with the support pipe 7 and fixed on the outer support cover 503.
  • A rotary adjusting wheel 9 is provided on the fixed seat 501, the adjusting wheel 9 being placed vertically. An adjusting groove 11 disposed along an involute 10 is provided on one surface of the adjusting wheel 9. The involute 10 is provided on a plane where the one surface of the adjusting wheel 9 is located. The end of the movable arm 502, connected to the fixed seat 501, is provided with a positioning column 505 having one end extended into the adjusting groove 11. Certainly, the positioning column 505 may also be integrated with a component on the movable arm 502. An adjusting member 12 is connected to the adjusting wheel 9. The adjusting wheel 9 is driven to rotate by an external force through the adjusting member 12. Certainly, the adjusting member may also be integrated with the adjusting wheel. As an improvement in this embodiment, the adjusting member 12 is an adjusting knob. The adjusting wheel 9 is connected to the adjusting knob through a rotating shaft 13 which is mounted on the fixed seat 501. The adjusting wheel is located within the fixed seat 501, while the adjusting knob is located outside the fixed seat 501.
  • When in operating, when the adjusting knob is rotated clockwise, the rotation of the adjusting wheel against the gravity of the upper plate allows the movable arm to ascend gradually, thereby realizing upward adjustment; and when the adjusting knob is rotated counterclockwise, the movable arm may be descended gradually, thereby realizing downward adjustment. Therefore, it is convenient and easy for adjustment. Fig. 8 is a diagram showing a position relation between the adjusting wheel and the positioning column when the upper plate is in a lowest position. Fig. 9 is a diagram showing a position relation between the adjusting wheel and the positioning column when the upper plate is in a middle position. Fig. 10 is a diagram showing a position relation between the adjusting wheel and the positioning column when the upper plate is in a highest position.
  • The following describes the working principle. The infinite-adjustment function of the present invention is realized on the basis of the principle of the involute. The fixed seat is in telescopic connection to the movable arm, that is, the fixed seat and the movable arm may be movable. When the adjusting wheel is rotated, the adjusting groove rotates along with the adjusting wheel. However, as one end of the positioning column is located within the adjusting groove, the position of the positioning column is changed. This change in position embodies in the vertical direction, the positive direction or the negative direction only. As a result, the position of the positioning column is changed and the position of the movable arm is also changed. In this embodiment, the support pipe is also changed, so the height of the upper plate may be changed to realize the function of ascending or descending. As the adjusting groove is disposed along the involute, the position of the positioning column may be changed until the height of the upper plate changes smoothly. Furthermore, the baby walker is linear, so it may fit the height of a baby easily, flexibly and properly even if there is a baby in the baby walker. It is easier to meet the demand of adjustment. The present invention uses fewer components and is simple in structure and low in cost.
    • Embodiment 2:
  • This embodiment is characterized in that the fixed seat is fixed on the upper plate and the movable arm is fixed on the lower plate. The position of the fixed seat and the position of the movable arm are exchanged with respect to those in Embodiment 1, but the implementation principle is the same as that in Embodiment 1.
  • As the baby walker with an infinite-adjustment function provided by the present invention has an infinite-adjustment function, and the adjusting groove is disposed along the involute, the position of the positioning column may be changed, when the upper plate is ascended or descended, so that the height of the upper plate changes smoothly; furthermore, the baby walker is linear, so it may fit the height of a baby easily, flexibly and properly. The baby walker requires fewer components and is simple in structure and easy in manufacturing.
