Description
Technical field
This utility model relates to a kind of medical apparatus system, particularly relates to a kind of operation shadowless lamp tower crane.
Background technology
Medical hoist tower is requisite armarium in hospital modernization intensive care unit, and it can facilitate medical personnel to rational distribution cable unified after patient's diagnosis and treatment, and for the outlet terminal of various medical gas pipeline, easy to use and reliable.The capital equipment that tower crane is installed is shadowless lamp, for surgical light.Because each patient's operative site is different, the position of operation table is also different, therefore need the position of frequent mobile shadowless lamp, and the position of other equipment on tower crane, its angle range reaches 340 °, for making lamp holder movement arbitrarily in range of activity, therefore, the junction of balance rotating arm and cantilever main shaft is a necessary rotatable movable joint.
Shadowless lamp on tower crane and other medical equipments all need energising; general operation shadowless lamp adopts junction block, wiring cap or brush to connect; in use when lamp holder frequently rotates; wiring cap, junction block very easily come off; cause short circuit or open circuit; brush may cause sparking to cause loose contact once similar fault occurs will have influence on operation and carry out, crisis patient safety.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, a kind of Novel operating astral lamp tower crane is provided, it can effectively be avoided because of equipment such as frequent mobile shadowless lamps, and rotating shaft causes short circuit or open circuit, ensure that the safety of formality.
The technical scheme that this utility model adopts is: this utility model operation shadowless lamp tower crane comprises tower crane bearing, tower crane bearing inner chamber is provided with cantilever main shaft, described cantilever main shaft arranges at least one counter-jib, described counter-jib all can around cantilever main axis, pipeline penetrates into counter-jib from cantilever main shaft, be electrically connected the shadowless lamp be installed on counter-jib or electrical outlet again, described cantilever main shaft is positioned at counter-jib junction and is provided with conducting slip ring, conducting slip ring penetrates be electrically connected conducting slip ring for wire with cantilever main shaft contact surface being provided with bore a hole, described counter-jib is provided with the electroconductive elastic sheet corresponding with conducting slip ring, electroconductive elastic sheet end is pressed on conducting slip ring, described counter-jib is positioned at and electroconductive elastic sheet contact surface is provided with perforation and penetrates for wire and be electrically connected with electroconductive elastic sheet.
By such scheme, described counter-jib and cantilever main shaft junction are provided with damping adjusting nut.
By such scheme, one end end that described electroconductive elastic sheet contacts with conducting slip ring outwards tilts.
By such scheme, between described conducting slip ring, be also provided with insulation bulge loop.
The conducting slip ring be contained on cantilever main shaft plays the effect of coaxial three core sockets, and the coaxial three-prong plug of the electroconductive elastic sheet that two counter-jibs are arranged, compresses with conducting slip ring.
This utility model beneficial effect is:
1, wire intertwist is avoided, and the situation that cannot conduct electricity, reduce shadowless lamp tower crane short circuit, open circuit and loose contact phenomenon and occur, improve the stability of circuit;
2, the rapid abutting joint of signal is realized, and can transmit communications signals and the signal of telecommunication;
3, because electroconductive elastic sheet end outwards tilts, no matter clockwise the or reversion of counter-jib all can not have been stretched tight by electroconductive elastic sheet, prevents electroconductive elastic sheet from breaking down;
4, structure is simple, cheap for manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model shadowless lamp tower crane;
Fig. 2 is the partial enlarged drawing of Fig. 1.
Detailed description of the invention
