Description

The revolving door conducting ring

Technical field

The utility model belongs to a kind of electric equipment, especially a kind of conducting ring that is used for automatic revolving door.

Background technology

At present, in many cities, no matter large-scale automatically-controlled door, automatic revolving door are in public places such as hotel, markets, still in Party and government offices, enterprises and institutions all everywhere as seen; Large automatic revolving door, automatically-controlled door machinery structure are divided into fixed gate body and revolving door body two large divisions, owing to adopt the microcomputer automatic control technology, need a large amount of signals to pass between fixed gate body and the revolving door body and exchanges data and power distribution, this exchanges data and power distribution utilize conducting ring to finish, so conducting ring plays a part very important in the running of automatic revolving door.The revolving door conducting ring product overwhelming majority depends on import at present, though the domestic special instructions for use that has similar products can not satisfy revolving door on performance, above-mentioned both exist following deficiency respectively:

1, imported product adopts metallic brush silk principle, whole pressing mold process technology, and the technological requirement height, technical sophistication, price are very expensive, and owing to adopt integrated artistic, maintenance is inconvenient in addition;

2, the home products conducting ring adopts the carbon brush principle, contact the effect of playing conduction with carbon brush by copper ring, but its technology is too simple, and machining accuracy is very low, and number of rings is few and volume is big, and carbon brush weares and teares easily, and useful life is short, needs often maintenance.

Summary of the invention

The utility model technical issues that need to address provide a kind of revolving door conducting ring, its compact conformation, and number of rings is many and volume is little, and long service life is stable and reliable for performance, and is easy to maintenance and cost of manufacture is low.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of revolving door conducting ring includes shell body, inner housing, conduction ring plate, brush guide frame, power supply fitting, power line, and the number of above-mentioned conduction ring plate is 2～20, stacks up and down along the axis of housing, lays insulating trip between the conduction ring plate; The surface of this conduction ring plate is provided with protective layer, and also is provided with conductive filament corresponding with it in a side of each conduction ring plate.

Protective layer on the described conduction ring plate is for evenly plating rhodium metal on copper conduction ring plate; The thickness of described conduction ring plate is 1.5～2.5mm; The diameter of described conductive filament is 0.5～1.2mm; The thickness of described insulating trip is 0.8～1.5mm.

Owing to taked above-mentioned scheme, the advantage that the utility model is compared with prior art had is:

1, owing to adopt the conduction ring plate of rhodanizing and contacting of conductive noble metal silk, can stable, good, the long service life of resistance to wear of guaranteed performance;

2, owing to use thin conduction ring plate and insulating trip, and adopt the mode that stacks, so the volume of integral body is greatly reduced, the number of rings of compact conformation and conduction ring plate is many;

3, owing to adopt the composite type design, greatly reduce cost of manufacture.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Fig. 1 is the structural representation of the utility model revolving door conducting ring.

Embodiment

As shown in Figure 1, the utility model revolving door conducting ring is made up of external member, working component and mounting structure.

Its outer member includes power supply fitting 1, protective cover 2, shell body 3 and inner housing 7, and shell body 3 and inner housing 7 constitute the semiclosed circular shell that a center has through hole, are formed by the metallic aluminium casting; Be with a protective cover 2 on the outer surface of shell body 3, the both sides of protective cover 2 are equipped with power supply fitting 1.

Workpiece is made up of insulating case 5, power line 10, insulating trip 11, conduction ring plate 12, conductive filament 13 and brush guide frame 14, adopt 101 nylon to make insulating case 5 and insulating trip 11, the thickness of this insulating trip 11 is 1mm, and the thickness of adorning copper rhodanizing on insulating case 5 is the conduction ring plate 12 of 2mm, totally 19, and each conduction ring plate 12 usefulness insulating trips 11 isolation and fix with nut; Be provided with the brush guide frame of being made by bakelite 14 in the outside of insulating trip 11, being fixed with 19 diameters with insulating cement on this brush guide frame 14 is 0.8mm and the conductive filament 13 made by wear-resisting precious metal material; The power line 10 that links to each other with copper rhodanizing ring plate evenly distributes vertically and draws from insulating case 5 end faces, and the lead-in wire of conductive filament 13 is drawn by power supply fitting 1.

Mounting structure is made up of lid 4, external pressure nut 6, interior clamp nut 8, lining 9 and bearing 15.

The operation principle and the use of the utility model revolving door conducting ring: workpiece is packed in the aluminium casing that external member forms, utilize mounting structure to carry out combine and assemble, then whole casing is fixed on the transmission central shaft of revolving door; The rotation of transmission central shaft simultaneously, drive the rotation of this conducting ring, utilize being in contact with one another of conduction ring plate 12 and conductive filament 13,, finish that a large amount of signals passes on and exchanges data and power distribution between fixed gate body and the revolving door body again by the drawing of power line 10 and power supply fitting.
