The specific embodiment
For further setting forth essence of the present utility model, by reference to the accompanying drawings the specific embodiment of the present utility model is described as follows.
Leverage embodiment
As shown in Figure 1, a kind of seat leverage, comprise: lever bracing frame 1, be arranged on the cushions support 2 on the lever bracing frame 1, the backrest bent plate 3 that is slidingly connected with cushions support 2, it is characterized in that described backrest bent plate 3 flexibly connects lever bracing frame 1 and cushions support 2 by connecting rod 4, the first crank connecting links 5 and second crank connecting link 6.Further, the motion for convenient control backrest bent plate 3 also fixedly has the motor 7 that is connected with backrest bent plate 3 on the described cushions support 2.
Wherein, as shown in Figure 2, described cushions support 2 is provided with the slideway that holds backrest bent plate 3; Have three not links on same straight line on described first crank connecting link 5.Preferably, described first crank connecting link 5 is " L " shape of bending.
In the present embodiment, described connecting rod 4, first crank connecting link 5 and second crank connecting link 6 and lever bracing frame 1, cushions support 2, the movable connection structure of backrest bent plate 3 refers to:
One end of connecting rod 4 is connected with backrest bent plate 3 by connecting axle 3-4, and the other end of connecting rod 4 is connected with an end of first crank connecting link 5 by connecting axle 4-5;
The other end of first crank connecting link 5 is connected on the lever bracing frame 1 by connecting axle 1-5, and the intermediate ends of first crank connecting link 5 is connected with an end of second crank connecting link 6 by connecting axle 5-6;
The other end of second crank connecting link 6 is connected with cushions support 2 by connecting axle 2-6.
In other embodiments, described connecting axle can replace with hinge, is not limited to present embodiment.
Particularly, its operation principle of the described leverage of present embodiment is: when motor pulling backrest bent plate 3 is lain down backrest, connecting rod 4 promotes first crank connecting link 5 and second crank connecting link 6 is in straight configuration, as shown in Figure 3, at this moment cushions support 2 can recede, and then drives receding of medicated cushion.On the contrary, when motor promotion backrest bent plate 3 was holded up backrest, connecting rod 4 promotes first crank connecting links 5 and second crank connecting link 6 is in folded state, and as shown in Figure 4, at this moment, cushions support 2 can travel forward, and then medicated cushion is flat.
From ergonomics and comfortable angle, the motion of medicated cushion and backrest is suitable between 1:3-1:5 than the scope of 1:X; The meaning of 1:X in other words, the medicated cushion revolution is crossed 1 °, backrest just turns over X °.As shown in Figure 3, Figure 4, in the present embodiment, it is 0 ° that the setting backrest is lied down minimum, and backrest is rotating in the angular range of 0-α under the drive of motor, and medicated cushion is the equidirectional angle beta that turns over correspondence under the effect of leverage.
β=（1/3~1/5）*α
By adjusting the relevant parameter of leverage, can determine required α and β.Here, we have adopted following parameter: α=0 ° ~ 65 °, β=0 ° ~ and, 13.6 °.That is to say that it is 0 that the setting backrest is lain minimum, backrest rotates between 0 ° ~ 65 ° along guide rail under the drive of motor, and medicated cushion is the equidirectional angle that turns over correspondence under the effect of leverage, is 0 ° ~ 13.6 °.In other embodiments, by adjusting the relevant parameter of leverage, the slewing area of backrest can expand to 0 ° ~ 70 °, and medicated cushion equidirectional angle that turns over correspondence under the effect of leverage is 0 ° ~ 14.5 °; Or press other angular ranges that 5:1-3:1 determines, be not limited to present embodiment.
A kind of leverage that is applied to dental chair that present embodiment provides, adopt connecting rod, first crank connecting link, second crank connecting link that lever bracing frame, cushions support and backrest bent plate are flexibly connected, only need to drive the backrest bent plate, motion when can realize backrest and medicated cushion, simple in structure, easy to operate.
The tooth chair embodiment
As shown in Figure 5, a kind of rotatable dental chair based on aforementioned leverage, comprise: base 8, be arranged on the elevating mechanism 9 on the base 8, be arranged on the leverage on the elevating mechanism 9, be positioned at medicated cushion 10 and backrest 11 on the leverage, it is characterized in that, described medicated cushion 10 and backrest 11 are for being rotatably connected.
In the present embodiment, described backrest 11 has one to rotate angle with its lowest order under the drive of backrest bent plate, and the scope of this rotation angle is 0 °-70 °; Accordingly, described medicated cushion 10 has an angle of rotation with cushions support, and the scope of this angle of rotation is 0 °-14.5 °.
A kind of rotatable dental chair that present embodiment provides is arranged on 0 °-70 ° by the rotation angle with backrest and lowest order, and the medicated cushion rotational angle is arranged on 0 °-14.5 ° accordingly, makes patient's seating very comfortable.
The above specific embodiment has been described in detail essence of the present utility model, but can not come protection domain of the present utility model is limited with this.In every case according to the essence of this utility model, the simple modifications of doing and modification all drop within the claim protection domain of the present utility model.
