Description

Double-body three-angle locking brush holder

Technical Field

The utility model belongs to equipment for the electric power industry, in particular to binary formula triangle degree locking brush holder.

Background

At present, existing brush holders at home and abroad are two conductive surfaces at a single angle, the actual conductive surface is less than 50%, the conductive surfaces are not in tight contact, ignition is easy to occur under the condition of increasing the spring pressure, the temperature of a slip ring is too high, the abrasion of the slip ring is accelerated, the service lives of the slip ring and a motor are influenced, and the carbon brush needs to be replaced in 4-5 months due to the fact that the spring pressure is too high, the price of the carbon brush is very high, and the production cost is increased.

Disclosure of Invention

The utility model aims to overcome the technical insufficiency and provide a binary type three-angle locking brush holder with compact structure, good conductive effect and long service life.

The utility model provides a technical scheme that technical problem adopted is: the double-body type triangular locking brush holder comprises a handle, a baffle, a pressing bowl, a brush box, a pressing brush plate, a shaft and a conductive frame, and is characterized in that two conductive frame mounting grooves are formed in a brush holder seat, a hook plate which is in the same shape as the bottom surface of the brush holder seat is fixed below the brush holder seat through bolts and gaskets, two driving lever sliding seats are arranged below the hook plate and correspond to driving levers, triangular locking surfaces are arranged on the driving lever sliding seats, semi-circular arc-shaped driving lever grooves and driving lever sliding slope surfaces are arranged corresponding to driving lever holes, the driving levers are arranged at the lower end of the shaft, and the shaft is fixed below the handle through a first bolt, a first gasket and a first spring gasket.

The utility model has the advantages that: the double-body three-angle locking brush holder has the advantages that the contact of the conductive surfaces is tight, the conductive effect is good, the carbon brush is saved, the service life of the whole brush holder is long, the wear speed of the slip ring is reduced due to the slow wear of the carbon brush, the consumption of the carbon powder is saved, the environment is protected, and the production cost is saved.

Detailed Description

In the embodiment, referring to fig. 1-5, a two-body type triangular locking brush holder is that a conductive frame 17 is arranged in two conductive frame mounting grooves 1-1 on a brush holder seat 1, and the conductive frame 17 is fixed on a body 23 by a second bolt 14, a second gasket 15 and a second spring gasket 16. The center of the upper part of the body 23 is provided with a spring seat 13, a spring 12 is arranged in the spring seat 13, the spring 12 is covered by a pressure bowl 5 above the spring seat 13, a baffle plate 4 is arranged above the pressure bowl 5, a first bolt 8, a first gasket 9, a first spring gasket 10 and a fixed handle 3 are arranged above the baffle plate 4, and a spiral ring 11 and the baffle plate 4 are arranged on one side of the handle 3 for reinforcement. The lower part of the handle 3 is connected with a shaft 18, the lower end of the shaft 18 is provided with a notch, a horizontal adjusting pressure rod 19 is arranged in the notch by a nut 20 and a spring washer three 21, and the lower end head of the shaft 18 is provided with a deflector rod 6. The lower surface of the brush holder seat 1 is fixed with a hook plate 2 by four bolts, a deflector rod sliding seat 2-1 is arranged below the hook plate 2 and corresponding to a deflector rod 6, a triangular locking surface 2-4 is arranged on the deflector rod sliding seat 2-1, and a semicircular deflector rod groove 2-2 and a deflector rod sliding slope surface 2-3 are arranged in a hole corresponding to the deflector rod 6. In a rear view, the brush box 22 is fixed to the body 23 at the upper side thereof by means of a nut 25 and a washer 26, four constant pressure spring fixing grooves 22-1 are formed in the brush box 22, a constant pressure spring 24 is installed in the constant pressure spring fixing groove 22-1, and the upper end of the constant pressure spring 24 is fixed to the wall of the brush box 22 by press-fitting. A press brush plate 7 is arranged between the brush box 22 and the main body 23 through a pin 28, and four compression springs 27 are connected to the lower wall of the brush box 22 below the press brush plate 7.

The utility model discloses a use is: the original motor brush holder and the original brush holder seat are disassembled, the brush holder seat of the double-body three-angle locking brush holder is screwed up by screws for use, the gap between the bottom of the brush holder and the slip ring is adjusted to be 5mm, the brush holder is installed clockwise, the brush holder is turned to the right by 60 degrees, and the user can see that the brush holder handle 3 is parallel to the brush holder seat 1 and hear a click sound. When the carbon brush is replaced and checked, the brush holder is taken down and twisted by 60 degrees in the opposite direction, so that the handle 3 is perpendicular to the brush holder 1, and the carbon brush is fast to disassemble and assemble.
