Detailed Description
The electric waist support adjusting device of the utility model is further described with reference to fig. 1 to 4.
The utility model provides a waist holds in palm electric adjusting device which characterized by: comprises a positioning plate 2, a driving rod 8, a swinging rod 4, a waist supporting plate 6 and a push rod 3. The positioning plate 2 is provided with an arc-shaped guide groove 213 and a straight guide groove 221, and an extension line of the straight guide groove 221 passes through a circle center 232 of the arc-shaped guide groove 213. The swing lever 4 has a first positioning pin 41 and a second positioning pin 42 arranged in the longitudinal direction, the first positioning pin 41 being located at a first end position of the swing lever 4 and fitted in the arc-shaped guide groove 213, and the second positioning pin 42 being located at an intermediate position of the swing lever 4 and pin-fitted in the linear guide groove 221. The middle part of the driving rod 8 is hinged to the circle center position 232 of the corresponding arc-shaped guide groove 213 of the positioning plate 2 through a pin rod, one end of the driving rod 8 is rotatably connected to the first positioning pin 41, and the other end of the driving rod 8 is hinged to the push rod 3 through a pin rod, which is an electric push rod in this embodiment. The waist rest 6 is connected to the outer end of the oscillating lever 4, i.e. the waist rest 6 is connected to the second end of the oscillating lever 4.
As shown in fig. 2, the positioning plate 2 has a cross-shaped structure and includes a first plate 21, and a second plate 22 and a third plate 23 formed on two sides of the first plate 21, the arc-shaped guide slot 213 is located on the first plate 21, the linear guide slot 221 is located on the second plate 22 and perpendicular to the first plate 21, and a circle center 232 corresponding to the arc-shaped guide slot 213 is located on the third plate 23. This structure can reduce the size of the positioning plate 2 as much as possible to improve the compactness of the entire apparatus.
A tension spring 5 is disposed between the positioning plate 2 and the swing lever 4, that is, a third positioning pin 231 is disposed on the third plate 23, a fourth positioning pin 43 is disposed on the swing lever 4, and both ends of the tension spring 5 are respectively hooked on the third positioning pin 231 and the fourth positioning pin 43. The tension spring 5 can make the swing rod 4 swing more stably and smoothly.
