Abstract
The utility model provides a horizontal compensation mechanism for a dental chair. A guide rail is arranged between a left side plate and a right side plate. An arc groove is formed in the guide rail, and the shape of the arc groove is matched with that of a bent plate. The lower end of the bent plate penetrates through the arc groove and is connected with one end of an active connecting rod. The other end of the active connecting rod is connected with a seat cushion support located above the left side plate and the right side plate. One end of the seat cushion support is fixedly connected with an extending plate. The two sides of the other end of the seat cushion support are connected with the left side plate and the right side plate through passive connecting rods. A motor supporting plate used for supporting a direct current motor is arranged at the end of the left side plate and the end of the right side plate. A motor shaft of the direct current motor is connected with the inner side of the bent plate and drives the bent plate to conduct reciprocating movement along the arc groove, so that the driving connecting rod is made to drive the seat cushion support and the extending plate to conduct horizontal movement and vertical movement at the same time. When the horizontal compensation mechanism for the dental chair moves, transmission is stable, generated resonance noise is small, it can be guaranteed that the seat cushion support conduct vertical movement and horizontal movement at the same time during pitching of a backrest, the phenomena that the back is rubbed and the human body is pressed are avoided, and therefore a patient can sit on the dental chair comfortably.
Description
Technical field
This utility model relates to a kind of level compensating mechanism for dental chair.
Background technology
Existing dental chair backrest pitch rotation mechanism, the structure that great majority adopt bent plate to rotate along fixed pivot, the dental chair structure of its type takes up room larger, rotating fulcrum location comparison is high in use simultaneously, cause patient to take uncomfortable, and back rest cushion there will be serious chopping phenomenon in motor process, seat cushion is also easily damaged; Also the backrest luffing mechanism having designs guide rail in dental chair, adopts this kind of drive, owing to there is no level compensating effect, unsatisfactory equally in back movement process, is therefore necessary to improve.
Utility model content
The technical problem that this utility model solves: a kind of level compensating mechanism for dental chair is provided, and the reciprocating motion by bent plate in arcuate groove, makes drive connecting rod drive seat support to produce and move up and down in horizontal movement.
The technical solution adopted in the utility model: for the level compensating mechanism of dental chair, there is bent plate, direct current generator, seat support, extending-board, left plate and right plate, between described left plate and right plate, be provided with on guide rail and guide rail and be shaped with and the identical arcuate groove of bent plate shape, described bent plate upper end is back rest supports plate fixedly, bent plate lower end is passed arcuate groove and is connected with drive connecting rod one end, the described drive connecting rod other end is connected with the seat support that is positioned at left plate and right plate top, and seat support one end is fixedly connected with extending-board, the both sides of the described seat support other end are connected with right plate with left plate respectively by passive connecting rod, in the end of left plate and right plate, be provided with the motor support plate that supports direct current generator, thereby the motor shaft of described direct current generator is connected driving bent plate to be moved back and forth and makes drive connecting rod drive seat support and extending-board to produce and move up and down in horizontal movement along arcuate groove with bent plate inner side.
Further, described guide rail two ends are fixed between left plate and right plate, and the nock place of described arcuate groove is provided with the screw that prevents from deviating from when bent plate from moving back and forth.
Stable drive when this utility model compared with prior art moves, to produce resonance sound little, can guarantee again in backrest pitching process that seat support is upper and lower and horizontal movement is synchronous, there will not be chopping and health to oppress phenomenon, and patient is sat with comfortable.

The specific embodiment
Below in conjunction with accompanying drawing 1-5, a kind of embodiment of the present utility model is described.
Level compensating mechanism for dental chair, there is bent plate 1, direct current generator 3, seat support 6, extending-board 10, left plate 5 and right plate 11, between described left plate 5 and right plate 11, be provided with on guide rail 7 and guide rail 7 and be shaped with and the identical arcuate groove 12 of bent plate 1 shape, specifically, described guide rail 7 two ends are fixed between left plate 5 and right plate 11, the nock place of described arcuate groove 12 is provided with the screw that prevents from deviating from when bent plate 1 from moving back and forth, bent plate 1 can be slided by guide rail arcuate groove 12, but can not swing.Described bent plate 1 upper end is back rest supports plate fixedly, bent plate 1 lower end is passed arcuate groove 12 and is connected with drive connecting rod 9 one end, described drive connecting rod 9 other ends be positioned at left plate 5 and be connected with the seat support 6 of right plate 11 tops, and seat support 6 one end are fixedly connected with extending-board 10, the both sides of described seat support 6 other ends are connected with right plate 11 with left plate 5 respectively by passive connecting rod 4, in the end of left plate 5 and right plate 11, be provided with the motor support plate 8 that supports direct current generator 3, thereby the motor shaft 2 of described direct current generator 3 is connected driving bent plate 1 to be moved back and forth and makes drive connecting rod 9 drive seat support 6 and extending-board 10 to produce and move up and down in horizontal movement along arcuate groove 12 with bent plate 1 inner side.
During use, this utility model is arranged on the mounting of dental chair, start direct current generator 3, the motor shaft 2 of direct current generator 3 drives bent plate 1 in the interior reciprocating motion of arcuate groove 12, bent plate 1 drives drive connecting rod 9 motions, drive connecting rod 9 drives seat support 6 to produce and move up and down in horizontal movement, can synchronously realize leg lift function and horizontal movement, and patient is sat with more comfortable.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting this utility model practical range, and the equivalence of being done with content described in this utility model claim therefore all changes, within all should being included in this utility model claim scope.
