Detailed description of the invention
As shown in Figure 1 to Figure 3, seat lifting structure, comprises base 1, lower gear parallel shelf 2, the parallel shelf 3 that cogs, bottom plate 41, bottom plate 42, upper mounted plate 51, upper mounted plate 52, linear electric motors 6, connecting lateral plate 71, connecting lateral plate 72, support side plate 81, support side plate 82; One end of lower gear parallel shelf 2 is connected to base 1 rotationally, the both sides of the other end of lower gear parallel shelf 2 rotationally correspondence are connected to connecting lateral plate 71, connecting lateral plate 72, cog parallel shelf 3 one end both sides rotationally correspondence be connected to connecting lateral plate 71, connecting lateral plate 72, cog parallel shelf 3 the other end both sides rotationally correspondence be connected to support side plate 81, support side plate 82, lower gear parallel shelf 2 and cog between parallel shelf 3 and be provided with engaging mechanism; The two ends of bottom plate 41 rotationally correspondence are connected to base 1, connecting lateral plate 71, the two ends of bottom plate 42 rotationally correspondence are connected to base 1, connecting lateral plate 72, the two ends of upper mounted plate 51 rotationally correspondence are connected to connecting lateral plate 71, support side plate 81, and the two ends of upper mounted plate 52 rotationally correspondence are connected to connecting lateral plate 72, support side plate 82; The body 61 of linear electric motors 6 is connected to base 1 rotationally, and the catch bar 62 of linear electric motors 6 is connected to the parallel shelf 3 that cogs rotationally.
The operation principle of above-mentioned seat lifting structure: when the catch bar 62 of linear electric motors 6 launches, catch bar 62 promotes to cog parallel shelf 3, under the restriction of the transmission of engaging mechanism, spacing and bottom plate (41,42), upper mounted plate (51,52), cog parallel shelf 3 and lower gear parallel shelf 2 upwards launches, thus make support side plate 81, support side plate 82 vertically rises.When the catch bar 62 of linear electric motors 6 does and shrinks, catch bar 62 drives the parallel shelf 3 that cogs downward, and cog parallel shelf 3 and lower gear parallel shelf 2 are amounted to downwards, thus make support side plate 81, support side plate 82 vertically declines.
Above-mentioned seat lifting structure, linear electric motors 6 are utilized to promote to cog parallel shelf 3, in conjunction with the transmission of engaging mechanism and spacing, can make seat in lifting process, keep front and back position constant with the object reaching vertical lift, usage space is relatively little, and rising or falling speed is fast, structure is simple, is convenient to I&M.In addition, utilize lower gear parallel shelf 2, supporting component that the parallel shelf 3 that cogs, upper mounted plate (41,42), bottom plate (51,52) and connecting lateral plate (71,72) are formed, effectively ensure that rigidity and the intensity of support.
One of them embodiment, also comprises air spring 9, and one end of air spring 9 is connected to base 1 rotationally, and the other end of air spring 9 is connected to the parallel shelf 3 that cogs rotationally.The program utilizes air spring 9 to play the effect of buffering, makes upgrading more stable, uses in dental multipurpose therapy unit, patient can be allowed more comfortable in lifting.
One of them embodiment, lower gear parallel shelf 2, the parallel shelf 3 that cogs are and are integrated into.Effectively ensure that rigidity and the intensity of support further.
Wherein, lower gear parallel shelf 2 is quadrilateral frame.The parallel shelf 3 that cogs comprises quadrilateral frame 31 and is located at the connecting rod 32 on quadrilateral frame 31.
Cog in parallel shelf 3 above-mentioned, the catch bar 62 of linear electric motors 6, the other end of air spring 9 are connected to this connecting rod 32 all rotationally.
One of them embodiment, engaging mechanism comprises the lower gear 11 be located on lower gear parallel shelf 2 and is located to cog parallel shelf 3 cogs 12, and lower gear 11 12 to engage with cogging.A kind of concrete structure of the present embodiment engaging mechanism that has been concrete illustrates, not limiting engaging mechanism is only this concrete structure.Herein means out, all engaging mechanisms can be applied to the application's scheme.
One of them embodiment, lower gear 11, cogging 12 can be respectively all gear or half gear.Certainly, lower gear 11, cogging 12 can be designed to according to the scope of rotating not be the non-all gear of half gear.
This detailed description of the invention also provides a kind of dental multipurpose therapy unit, comprises the seat lifting structure of seat (not shown) and above-mentioned any embodiment, and seat is connected in support side plate 81, support side plate 82.Above-mentioned dental multipurpose therapy unit employs above-mentioned seat lifting structure, similarly has following advantage: usage space is relatively little, and rising or falling speed is fast, and structure is simple, is convenient to I&M.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
