Description
Technical field
The invention belongs to medical apparatus and instruments rotary apparatus technical field, be specifically related to a kind of spittoon rotating mechanism for dental unit.
Background technology
Dental multipurpose therapy unit is generally used for inspection and the treatment of oral disease, is stomatologic main diagnostic equipment.Dental multipurpose therapy unit is primarily of a few major part composition such as main box, spittoon, apparatus arm, apparatus dish, assistant's frame, mouth lamp and supporting dental chair.It is in order in dental care process, patient can obtain spit preferably position or medical personnel and can obtain larger working place that spittoon rotates, the spittoon rotating mechanism of traditional dental multipurpose therapy unit, usual employing two kinds of rotation modes: one is manual rotation, employing axle sleeve coordinates, axle and spittoon are connected, cover is holder, manually carries out rotation and regulates spittoon position; Two is automatic rotations, take motor as power, by gear or other drive mechanisms, rotary motion is delivered to terminal, to realize the rotation of terminal, this when transmitting power by gear or other drive mechanisms, when speed reducing ratio is larger, transmission is irreversible, realize automatic rotation and then can not realize manual rotation simultaneously, if automatic rotation terminal is obstructed, equipment will damage.Above-mentioned defect, brings very big inconvenience to doctor's operation, is therefore necessary to propose to improve.
Summary of the invention
The technical problem that the present invention solves: a kind of spittoon rotating mechanism for dental unit is provided, in spittoon automatic rotation process, when spittoon runs into obstacle, the gear wheel of embedded magnet and power transmission shaft " skidding ", guarantee device security, simultaneously also can hand rotation spittoon.
The technical solution used in the present invention: for the spittoon rotating mechanism of dental unit, have and be fixed on spittoon motor on roof box and supporting seat, described spittoon motor output shaft is provided with pinion, power transmission shaft upper end be connected with spittoon rotating shaft lower end after common by bearings in supporting seat, wherein supporting seat is stretched out and supporting seat top excircle is provided with two limit switches in 90 degree of angles in spittoon rotating shaft top, when the position that supporting seat is exposed in spittoon rotating shaft is provided with at spittoon axis of rotation and the cam that touches of limit switch, there is the gear wheel engaged with pinion described power transmission shaft lower end by magnet adsorption, described spittoon rotating shaft upper end is fixedly connected with spittoon.
Wherein, described power transmission shaft bottom is provided with bulge loop, and described gear wheel end face is shaped with the groove holding Magnet, and described gear wheel end face is adsorbed on bulge loop lower surface.
Further, described power transmission shaft is shaped with radial slot and the both sides angle of radial slot is 180 degree, bolt to screw in supporting seat and inserts in radial slot simultaneously.
Further, described bulge loop upper surface is provided with packing ring, and the outer ring of bearing is resisted against on packing ring, and described bearing has two, between bearing, be provided with lining.
Further, described supporting seat top excircle is provided with switch fixed mount, and described limit switch is fixed on switch fixed mount.
The present invention compared with prior art adopts spittoon motorized motions; and by the magnetic-adsorption effect between gear wheel and power transmission shaft, transmit spittoon electronic rotation and realize spittoon automatic rotation or utilize " skidding " phenomenon between the two to make transmission lose efficacy and realize manual rotation and proterctive equipment safety.

Detailed description of the invention
Below in conjunction with accompanying drawing 1,2, a kind of embodiment of the present invention is described.
For the spittoon rotating mechanism of dental unit, have and be fixed on spittoon motor 1 on roof box 5 and supporting seat 6, described spittoon motor 1 output shaft is provided with pinion 14, jointly be supported in supporting seat 6 by bearing 7 after power transmission shaft 2 upper end is connected with spittoon rotating shaft 13 lower end, described bulge loop 16 upper surface is provided with packing ring 9, the outer ring of bearing 7 is resisted against on packing ring 9, described bearing 7 has two, lining 8 is provided with between bearing 7, wherein supporting seat 6 is stretched out and supporting seat 6 top excircle is provided with two limit switches 11 in 90 degree of angles in spittoon rotating shaft 13 top, the cam 15 that position is provided with when spittoon rotating shaft 13 is rotated and limit switch 11 touches of supporting seat 6 is exposed in spittoon rotating shaft 13, described supporting seat 6 top excircle is provided with switch fixed mount 12, described limit switch 11 is fixed on switch fixed mount 12, described power transmission shaft 2 lower end is adsorbed with the gear wheel 4 engaged with pinion 14 by Magnet 3, described spittoon rotating shaft 13 upper end is fixedly connected with spittoon 10, described power transmission shaft 2 bottom is provided with bulge loop 16, and described gear wheel 4 end face is shaped with the groove 17 holding Magnet 3, and described gear wheel 4 end face is adsorbed on bulge loop 16 lower surface, described power transmission shaft 2 is shaped with radial slot 18 and the both sides angle of radial slot 18 is 180 degree, bolt 19 to screw in supporting seat 6 and inserts in radial slot 18 simultaneously.
When spittoon 10 rotates automatically, after starting spittoon motor 1, pinion 14 on spittoon motor 1 output shaft drives gear wheel 4 to rotate, Magnet 3 in gear wheel 4 groove 17 and bulge loop 16 adhesive of power transmission shaft 2, thus make power transmission shaft 2 drive the spittoon rotating shaft 13 of spline joint with it to rotate, finally the spittoon 10 being delivered to spittoon rotating shaft 13 upper end will be rotated, realize spittoon 10 automatic rotation, supporting seat 6 is fixed with switch fixed mount 12, limit switch 11 switch fixed mount 12 is equipped with, spittoon rotating shaft 13 there is cam 15, to control the position that spittoon 10 rotates, when spittoon rotating shaft 13 turns to one of them limit switch 11 that cam 15 touches on supporting seat 6, spittoon motor 1 quits work, now, spittoon 10 is static, when the position of spittoon 10 need be rotated, after starting spittoon motor 1, control spittoon 10 to rotate in the opposite direction, turn to cam 15 to touch spittoon motor 1 after another limit switch 11 and quit work, spittoon 10 also stops operating, in spittoon 10 automatic rotation process, when spittoon 10 runs into obstacle, gear wheel 4 and the power transmission shaft 2 of described embedded magnet 3 start " skidding ", can guarantee device security
During manual rotation spittoon 10, promote the assistant's frame pivoted arm being located at spittoon 10 lower end, now, the gear wheel 4 of embedded magnet 3 by magnetic-adsorption on power transmission shaft 2, when gear wheel 4 is fixed, hand push external force, when enough large, can relatively rotate between power transmission shaft 2 and gear wheel 4, namely be commonly called as " skidding ", realize spittoon 10 manual rotation; Hand rotation spittoon 10, because the speed reducing ratio of spittoon motor 1 is comparatively large, spittoon motor 1 output shaft can not rotate by drive motor, and gear wheel 4 is fixed, and now starts " skidding " between power transmission shaft 2 and gear wheel 4, realizes spittoon 10 manual rotation.
Above-described embodiment, just preferred embodiment of the present invention, is not used for limiting the scope of the present invention, therefore all equivalence changes done with content described in the claims in the present invention, all should be included within the claims in the present invention scope.
