Abstract
The utility model discloses a bracket and bed surface board locking device of an X-ray machine. The device comprises a coil component which consists of an iron core and a coil. The locking device is characterized in that the coil component is arranged in an outer cover and in a base seat under the bracket and the bed surface board; the coil is wound at the side face of the iron core; a permanent magnet is arranged between the lower end face of the iron core and the outer cover; the upper end face of the iron core is respectively contacted with the bracket and the bed surface board; the outer cover and the base seat are provided with a coil conducting wire leading opening; and a conducting wire is connected with a control power source. The device can prevent the X-ray machine from having long electrifying time under the work status, and has small power consumption, thereby being not only safe but also environment-friendly.
Description
Technical field
This utility model relates to a kind of medical X-ray machine, particularly relates to a kind of x-ray source assembly support, bed panel locking device of medical X-ray machine.
Background technology
At present, X-ray machine has been widely used in all kinds of medical institutions, the patient is checked take the photograph sheet.When using adjustment, the support of X-ray machine and bed panel can be according to checking that needs carry out displacement or rotation; And when in running order, promptly need support and bed panel are locked, so that observe and take the photograph sheet.Existing X-ray machine, the general electric magnet mode that adopts locks x-ray source assembly support, bed panel, its working method produces magnetic field for energising, be that electric magnet holds state, lock bracket and bed panel, outage back demagnetization (promptly unclamping electric magnet), x-ray source assembly support, bed panel can move freely.Adopt this electric magnet mode, need in the course of the work energising for a long time, power consumption is big, and easily causes electromagnetic radiation, and the person and diagnosis are impacted.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, provides a kind of long-time energising that do not need in the course of the work, New X ray machine support, bed panel locking device that power consumption is little.
The technical scheme that this utility model solution prior art weak point is taked is: a kind of X-ray machine support, bed panel locking device, comprise the coil block of forming by iron core, coil, coil block is placed in the overcoat, be installed in the base under support, the bed panel, coil is established a permanent magnet around the side of iron core between the lower surface of iron core and the overcoat, the upper surface of iron core contacts with support, bed panel respectively, overcoat and base have the winding wire outlet, and lead connects the control power supply.
Described iron core be shaped as boss shape, be surrounded by 3～4 layers of adhesive tape insulating barrier, coil is around the boss side surfaces of iron core, the line of coil directly is 0.25 millimeter, the number of turn is 1240 circles, and coil is surrounded by 5～6 layers of adhesive tape insulating barrier outward, and the upper surface of boss contacts with support, bed panel respectively.
Described permanent magnet be shaped as annular, adopt the SmCo magnet steel, magnetic circuit is oriented to axially.
Described coil upper/lower terminal is respectively equipped with the epoxy plate insulating trip, and upper end epoxy plate insulating trip is concordant with the iron core upper surface.
Described overcoat is made by pure iron, and the outside and the overcoat of coil block and permanent magnet leave the gap, and the lower surface and the overcoat of iron core are fixed by screw.
Described base is made by aluminium alloy.
The beneficial effects of the utility model are: permanent magnet and existing electric magnet are organically combined, permanent magnet lock bracket, bed panel have been realized utilizing when X-ray machine in working order, only when adjusting, just carry out of short duration energising demagnetization, broken through that prior art needs long-time energising, power consumption is big and easily caused the deficiency of electromagnetic radiation, not only safety but also energy-conserving and environment-protective.
Description of drawings
Fig. 1 is this utility model structural representation.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model is further described.
A kind of X-ray machine support of this utility model as shown in Figure 1, bed panel locking device are formed coil block by iron core 1, coil 2, coil block is placed in the pure iron overcoat 3, and be installed in the aluminium alloy base 4 under support, the bed panel (omitting among the figure).Coil is established a permanent magnet 5 around the side of iron core between the lower surface of iron core and the overcoat, permanent magnet be shaped as annular, adopt the SmCo magnet steel, magnet steel surface magnetic field intensity everywhere is 2200oe, magnetic circuit is oriented to axially, can guarantee that its lock ability is not less than 100N.The shaped design of iron core becomes boss shape, is surrounded by 3～4 layers of adhesive tape insulating barrier, and coil is around the boss side surfaces of iron core, and the line of coil directly is 0.25 millimeter, and the number of turn is 1240 circles, and coil is surrounded by 5～6 layers of adhesive tape insulating barrier outward.The upper surface A of iron core boss contacts with support, bed panel respectively, and it is smooth that upper surface A must keep, and keeps the S utmost point.Overcoat and base have winding wire 6 outlets 7, and lead connects control power supply (omitting among the figure).
Upper/lower terminal at coil is respectively equipped with epoxy plate insulating trip 8,9, and upper end epoxy plate insulating trip 8 is concordant with iron core upper surface A.The outside and the overcoat of coil block and permanent magnet leave the gap, and the lower surface of iron core and overcoat are fixing by screw 10, and screw passes from the inner radius of annular permanent magnet.All parts adopt adhering with epoxy resin firm.
The working method of x-ray source assembly support is: be lock-out state in operate as normal, promptly need not switch on, rely on the magnetic force of permanent magnet to hold support; When need change photography focal length or photography position, just need energising, after the energising demagnetization, magnetic flux is near zero, and support can move freely.
The working method of flotation bed panel is: bed panel is a lock-out state in operate as normal, promptly need not switch on, and relies on the magnetic force of permanent magnet to hold bed panel; When carrying out the positioning of photography, just need energising, promptly unclamp electric magnet, removable bed panel (patient lies on the bed panel) is to patient's the required sheet position of taking the photograph.
