The specific embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing and concrete embodiment:
A kind of angle regulator of blood-drawing chair back plate comprises the seat board frame 1, the backboard frame 2 that rotate and connect, and described seat board frame 1 is connected with seat, described backboard frame 2 is connected with backrest.
The rotating putting film 3 that is connected with in the bottom of described seat board frame 1, an end of described putting film 3 rotate with described seat board frame 1 and are connected.The bottom of described backboard frame 2 is provided with lead 6, slidably is arranged with axle sleeve 5 on the outer circle wall of described lead 6.The bottom of described backboard frame 2 is provided with the electric pushrod 4 with output shaft 41.The other end of described putting film 3 rotates with described axle sleeve 5 and is connected, and described output shaft 41 is connected with described axle sleeve 5.
In order to make motion of mechanism more steady, described putting film 3 is symmetrically arranged two, an end of two described putting films 3 all rotate with described seat board frame 1 be connected, the other end all rotates with described axle sleeve 5 and is connected.
Described lead 6 is symmetrically arranged two, has 51, two described leads 6 of two symmetrically arranged pilot holes on the described axle sleeve 5 and is plugged in respectively in the described pilot hole 51.The axial line of two described leads 6 all parallels setting with the end face of described backboard frame 2, and the axial line of two described leads 6 is all perpendicular to the rotational axis line of described backboard frame 2 with described seat board frame 1.
The both ends of two described leads 6 all are fixedly installed on the bottom of described backboard frame 2, and described axle sleeve 5 can slide on the cylinder of two described leads 6, can not break away from from described lead 6.
End with described output shaft 41 deviates from mutually of described electric pushrod 4 is connected by straight pin 7 with the bottom of described backboard frame 2, being connected of being connected of described output shaft 41 and described axle sleeve 5, described putting film 3 and described seat board frame 1, described putting film and described axle sleeve 5 be connected all connection by described straight pin 7.Though described electric pushrod 4 be by described straight pin 7 be connected with described backboard frame 2, described output shaft 41 is to be connected with described axle sleeve 5 by described straight pin 7, yet its essence is between described electric pushrod 4 and the described backboard frame 2 and fixedly connected.
Referring to the process from Fig. 8 to Fig. 7 to Fig. 6, when described output shaft 41 was protruding, described backboard frame 2 was turned up with respect to described seat board frame 1; Referring to the process from Fig. 6 to Fig. 7 to Fig. 8, when described output shaft 41 was inwardly withdrawn, described backboard frame 2 was set level with respect to described seat board frame 1.This principle can be represented with Fig. 5, the difference part of Fig. 5 principle and Fig. 2 principle is, what the slide block of Fig. 5 was represented is described axle sleeve 5, described axle sleeve 5 slidably is set on the described lead 6, and its moving rail trace and the end face of described backboard frame 2 are parallel and perpendicular to the pivot center of described backboard frame 2 with described seat board frame 1; Described putting film 3 is rotationally connected with described seat board frame 1, axle sleeve 5 homogeneous phases.When the described axle sleeve 5 of described electric pushrod 4 drivings slides, just cause the angle adjustment of described backboard frame 2 on described lead 6.Because described axle sleeve 5 can determine, not be subjected to the influence of described electric pushrod 4 length own in theory according to the actual requirements to the described backboard frame 2 and the distance of the pivot center of described seat board frame 1, therefore the angle between described in theory backboard frame 2 and the described seat board frame 1 can change between ± 90 °, and in fact also can realize the variation of scope between 0 ° to 80 ° easily, satisfy the demand of actual blood sampling chair, this moment is lower to the flexible area requirement of described output shaft 41.And adopt structural principle of the present invention, the tensile force of output shaft 41 or compression stress act directly on the described axle sleeve 5, the direction of power is identical with the direction of motion of described axle sleeve 5, and the utilization rate height of power, power 100% acting and motion are more steady in theory; Yet the structural principle of Fig. 2, steady phenomenons such as there is very mitre in the direction of motion of the direction of power and described backboard frame 2, and the utilization rate of power is low, power has only fraction to do work, the vibration when causing component movement easily with the vertical component of described backboard frame 2 directions of motion is trembled.
Above-mentionedly being the present invention's most preferred embodiment, is not limitation of the invention, every invention main points that meet the present invention, all should be at the row of protection of the present invention.
