Description

Roller structure of variable frequency generator

Technical Field

The utility model relates to the technical field of variable frequency generators, in particular to a roller structure of a variable frequency generator.

Background

With the rapid development of economy and the improvement of living standard of people, the variable frequency generator is more and more favored by people as an emergency power supply.

The variable frequency generator utilizes energy generated by gasoline or diesel combustion and finally converts the energy into electric energy, and because the variable frequency generator is generally practical outdoors, a user needs to frequently move the variable frequency generator in the use process. The existing variable frequency generator is characterized in that two sides of a chassis base plate are respectively provided with a roller, so that movement is realized.

The roller structure of the existing variable frequency generator is as follows: the two rollers are connected through a long shaft, and the long shaft penetrates from one side of the chassis base plate to the other side of the chassis base plate, so that the connection of the two rollers is realized. The defects are that: the long shaft penetrates through two sides of the chassis bottom plate, so that the long shaft is long and the material cost is high; meanwhile, the middle part of the long shaft can interfere with other parts of the variable frequency generator, and the overall spatial layout of the variable frequency generator is affected.

Therefore, how to provide a roller structure of a variable frequency generator, which has the advantages of less material consumption and space saving, is a technical problem to be solved by those skilled in the art.

The utility model aims at providing a roller structure of a variable frequency generator so as to reduce material cost and save occupied space.

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, fig. 1 is a schematic structural diagram of a roller structure of a variable frequency generator according to the present utility model; FIG. 2 is an exploded view of the roller and the roller seat according to the present utility model; FIG. 3 is a schematic view of a roller and a roller seat according to the present utility model; fig. 4 is a schematic overall perspective view of the variable frequency generator according to the present utility model.

The embodiment of the utility model discloses a roller structure of a variable frequency generator, which comprises the following components: chassis bottom plate 1, two gyro wheel seats 2 and two gyro wheels 3. The two roller seats 2 are arranged on two sides of the chassis base plate 1 at intervals, and the two rollers 3 are respectively arranged on the corresponding roller seats 2, so that the movement of the variable-frequency generator is realized. Each roller 3 is fixedly connected with a half shaft 4, and the half shaft 4 is rotatably arranged on the corresponding roller seat 2 through a bearing.

According to the roller structure of the variable frequency generator, in the practical application process, the two rollers 3 are arranged on the corresponding roller seat 2 through the two independent half shafts 4, so that the movement of the variable frequency generator is realized. Since the two rollers 3 are mounted on the corresponding roller seats 2 through the two independent half shafts 4, no connecting shaft exists between the two roller seats 2, so that the space between the two roller seats 2 is vacated for mounting other parts; meanwhile, compared with the traditional long shaft, the two half shafts are shorter in length, so that the connecting shaft between the two bearing seats 2 is saved, and the material cost of the connecting shaft is greatly saved.

In some embodiments, one end of the axle shaft 4 is fixedly connected to the roller 3, the other end extends through the roller seat 2, and the end of the axle shaft 4 remote from the end of the roller 3 forms an anti-slip portion 5 for preventing the axle shaft 4 from slipping off the roller seat 2. During actual manufacturing, the half shaft 4 can be rotatably arranged on the roller seat 2 through a bearing, and the anti-falling part 5 is formed at the end part of one end of the half shaft 4 far away from the roller 3, so that the situation that the half shaft 4 falls off from the roller seat 2 in the moving process of the variable frequency generator can be avoided, and the use stability is improved.

In other embodiments, the roller housing 2 is integral with the chassis floor 1. During manufacturing, the roller seat 2 and the chassis base plate 1 can be integrally injection molded, so that the stability of the roller seat 2 is improved.

Preferably, a reinforcing rib plate 6 is connected between the roller seat 2 and the chassis base plate 1, so that the strength and stability of the roller seat 2 are enhanced. In a more preferred embodiment, a plurality of reinforcing ribs 6 are connected between the roller seat 2 and the chassis base plate 1, and the plurality of reinforcing ribs 6 are sequentially arranged at intervals along the length direction of the roller seat 2, so that the strength and stability of the whole roller seat 2 are enhanced.

In other specific embodiments, the chassis base plate 1 is provided with a yielding portion 7 for yielding the roller 3 at the outer side of the roller seat 2, so that the overall appearance of the roller 3 after installation is attractive, and the external attractiveness of the variable frequency generator is improved.
