Abstract
The utility model relates to an aerify circuit breaker main shaft for cabinet. The technical scheme adopted comprises the following steps: the main shaft body, its characterized in that: the main shaft body includes cylinder portion and hexagonal prism portion at least be equipped with 3 sets of interval arrangement's deciliter turning arm group on the hexagonal prism portion, every group deciliter turning arm group forms by the deciliter turning arm monomer interval arrangement of 2 stamping forming, every deciliter turning arm monomer with hexagonal prism portion is welded fastening, every deciliter turning arm monomer top is equipped with the shaft hole. Has the advantages that: adopt welded fastening between main shaft and the deciliter connecting lever, the product is difficult to the production clearance when using after the installation to the problem that can not reach the circuit breaker disconnection effect takes place because the vacuum bubble is not expert when avoiding the circuit breaker combined floodgate or the vacuum bubble interval is not enough when breaking off.
Description
Technical Field
The utility model relates to an aerify circuit breaker main shaft for cabinet.
Background
The circuit breaker is one of the important subassemblies of aerifing the cabinet, and its structure mainly includes: frame, operating device and utmost point post. The operating mechanism is a power component inside the circuit breaker, drives the movable contact and the fixed contact contained in the vacuum bubbles in the pole columns to be combined and separated, is fixed in the middle of the frame and specifically corresponds to the middle positions of the pole columns. The upper part of the frame is arranged above the operating mechanism, the lower end of the frame is mechanically connected with the operating mechanism, and a vacuum bubble is arranged in the frame and used for accommodating the moving contact and the static contact. Traditional operating device's main shaft and establishing the structure of a plurality of deciliter connecting lever on the main shaft is shown as the chinese utility model patent that patent number is "201220695924.4", and it installs deciliter connecting lever on columniform main shaft, be the components of a whole that can function independently structure usually between main shaft and the deciliter connecting lever, the easy production clearance of installation back product when using, vacuum bubble is not expert when causing the circuit breaker to close a floodgate easily or the vacuum bubble interval is not enough when breaking off, does not reach circuit breaker disconnection effect. In addition, the traditional dividing and combining crank arms are all cast parts, so that the precision is low and the cost is high.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an integral type aerifys circuit breaker main shaft for cabinet.
In order to solve the above problem, the utility model discloses a technical scheme include: the main shaft body, its characterized in that: the main shaft body includes cylinder portion and hexagonal prism portion at least be equipped with 3 sets of interval arrangement's deciliter turning arm group on the hexagonal prism portion, every group deciliter turning arm group is formed by 2 stamping forming's deciliter turning arm monomer interval arrangement, every deciliter turning arm monomer with be welded fastening between the hexagonal prism portion, every deciliter turning arm monomer top is equipped with the shaft hole.
Aerify circuit breaker main shaft for cabinet, its characterized in that: the outer tip of hexagonal prism somatic part is equipped with stroke turning arm group, stroke turning arm group is formed by 2 stamping forming's stroke turning arm monomer interval arrangements, every stroke turning arm monomer with for welded fastening between the hexagonal prism somatic part, every stroke turning arm monomer top is equipped with the shaft hole.
Aerify circuit breaker main shaft for cabinet, its characterized in that: the end part of the hexagonal prism body part, which is close to the cylinder part, is provided with a key groove.
Aerify circuit breaker main shaft for cabinet, its characterized in that: the end part of the cylindrical part extends to form a hexagonal prism connecting part, and a cross-shaped hole and a straight-shaped hole are formed in the hexagonal prism connecting part.
Aerify circuit breaker main shaft for cabinet, its characterized in that: and an annular groove is formed at the position, close to the hexagonal prism body, of the cylindrical body.
The utility model discloses a aerify circuit breaker main shaft for cabinet advantage lies in: 1. adopt welded fastening between main shaft and the deciliter connecting lever, the product is difficult to the production clearance when using after the installation to the problem that can not reach the circuit breaker disconnection effect takes place because the vacuum bubble is not expert when avoiding the circuit breaker combined floodgate or the vacuum bubble interval is not enough when breaking off. 2. The splitting and combining crank arms are positioned and installed by adopting a hexagonal structure, so that the device has the characteristics of convenience in installation, accurate installation position and feasibility of a plurality of installation angles; 3. the dividing and combining crank arm is formed by arranging 2 dividing and combining crank arm monomers which are punched and formed at intervals, and has the advantages of high precision and low cost.
