Description
Technical field
The present invention relates to a kind of therapeutic instrument, specifically refer to a kind of therapy apparatus protective housing.
Background technology
During ionic curing machine treatment, according to different focuses, select the different treatment needle contact of diameter or insert in body foci, utilizing the high electric field intensity formed in the minimum air gap between contact and tissue to make gas molecule separate, produce plasma flame.When selecting to export by force, moment produces the high temperature of about 3000 DEG C, makes pathological tissues gasification disappear.Simultaneously as also have very thin solidification layer below gasification layer, can stop hemorrhage, protect surface texture, make wound heal rapidly.When select weak output time, can make lesion tissue solidification or carbonization and downright bad, with this reach treat purpose.
Ionic therapy apparatus effect the most on the market is extensive, but in medical procedure, outside the switch of ionic therapy apparatus is exposed to, extraneous dust or steam is easily accessible in the electronic circuit within therapeutic instrument, the most directly consequence is that switch key is the most malfunctioning when wound debridement so that after operation completes, therapy apparatus cannot stop immediately, and disturb the judgement for the treatment of personnel, cause malpractice.
Summary of the invention
It is an object of the invention to provide a kind of ionic curing machine, it is to avoid dust or the steam in the external world enter into therapeutic instrument inside through on & off switch and causes the malfunctioning of switch, and then reduce the fault rate of therapeutic instrument.
The purpose of the present invention is achieved through the following technical solutions:
A kind of therapy apparatus protective housing; including on & off switch and the protective housing having through hole; the sealing cavity of tubular it is provided with in described protective housing; seal and have annular groove on the inwall of cavity; sealing gasket is fixed in annular groove, and on & off switch is placed in annular seal space body through through hole, connects in the bottom of on & off switch and has one end to run through the motion bar sealing cavity bottom; being fixed with circular bottom plate on motion bar, the excircle of circular bottom plate contacts with sealing gasket all the time；Also include cam bit and fixed block; fixed block is arranged on protective housing inwall; cam bit is rotated by rotary shaft and is arranged in protective housing; and on rotary shaft outer wall, have coarse thread, and the side of motion bar is provided with cingulum, cingulum coordinates with coarse thread; rotate on fixed block and be provided with contact supporting; the side of contact supporting is provided with roller, and roller contacts with cam bit, and connecting in the bottom of contact supporting has contact；Being provided with contact base in the bottom of protective housing, contact base is fixed with contact chip, described contact chip is placed on the swing route of contact.When the present invention works, protective housing is embedded on therapeutic instrument casing, contact chip is connected with therapeutic instrument internal circuit by wire, on & off switch is pressed, circular bottom plate moves downwardly together with motion bar, the bottom of motion bar is run through sealing cavity bottom and is entered into inside protective housing, the side of motion bar is provided with cingulum, cingulum coordinates with the coarse thread in rotary shaft, drive cam bit rotates counterclockwise, contact condition between cam bit and roller becomes released state simultaneously, contact holder is a little swinging on fixed block under the effect of self gravitation, until contact is bonded together with contact chip collision, contact chip connects therapeutic instrument internal circuit by wire, therapeutic instrument is started normally work；When therapeutic instrument quits work, being lifted up by & off switch, motion bar drives cam bit to rotate clockwise, and cam bit keeps and the contacting of roller again so that contact separates with contact chip, and then therapeutic instrument is quit work.
Wherein, cam bit and the setting of contact holder, the connected mode that traditional switch flexure strip clashes into is become flexible connection, by the regulation of cam bit, can avoid switching the shock loss of flexure strip, be greatly improved the service life controlling switch；And sealing gasket can deform upon and then make circular bottom plate to contact with sealing gasket all the time in sealing cavity in annular groove; ensure fully sealing between the external world and protective housing inside; steam or the dust of stopping the external world enter into inside therapeutic instrument by & off switch; ensure the control function that switchs the most afterwards of therapeutic instrument and flexibility ratio; improve the service efficiency of therapeutic instrument, reduce the malpractice incidence rate caused because of malfunctioning switch simultaneously.
Being provided with screwed hole bottom described on & off switch, threadeds through screwed hole with on & off switch in the upper end of motion bar.During the use of upper time, having dust unavoidably and entered in bright cavity by through hole, on & off switch is threadeded with motion bar, can be disassembled by & off switch, convenient manually to sealing inside cavity cleaning, it is ensured that the tidiness in annular seal space body.
Also include that torsionspring, the two ends of described torsionspring are connected with contact supporting, fixed block respectively.Under on & off switch during pressure, cam bit separates with roller, contact is done under contact holder self gravitation effect and is freely swung, until with contact chip making contact, now, the torsionspring between fixed block and the frame of contact is stretched, according to active force and counteracting force, torsionspring provides one to contact holder and moves pulling force in opposite direction, it is to avoid excessively the colliding and cause impaired of contact and contact chip.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, the present invention; sealing gasket can deform upon and then make circular bottom plate to contact with sealing gasket all the time in sealing cavity in annular groove; ensure fully sealing between the external world and protective housing inside; steam or the dust of stopping the external world enter into inside therapeutic instrument by & off switch; ensure the control function that switchs the most afterwards of therapeutic instrument and flexibility ratio; improve the service efficiency of therapeutic instrument, reduce the malpractice incidence rate caused because of malfunctioning switch simultaneously；
2, the present invention, during the use of upper time, was had dust unavoidably and is entered in bright cavity by through hole, and on & off switch is threadeded with motion bar, can be disassembled by & off switch, convenient manually to sealing inside cavity cleaning, it is ensured that the tidiness in annular seal space body；
3, the present invention, contact is done under contact holder self gravitation effect and is freely swung, until with contact chip making contact, now, torsionspring between fixed block and the frame of contact is stretched, according to active force and counteracting force, torsionspring provides one to contact holder and moves pulling force in opposite direction, it is to avoid contact and excessively colliding of contact chip and cause impaired.
