Description

Adjusting screw of circuit breaker

Technical Field

The utility model relates to an adjusting screw, more specifically the circuit breaker adjusting screw that says so relates to.

Background

The adjusting screw of current circuit breaker product has a straight flute, cross recess isotructure, factory end adopts the manual mode of twisting of personnel to go to realize regulatory function mostly when actual operation, as shown in figure 1, current adjusting bolt structure mainly includes circular brain and the shank of bolt, and the one end at the shank of bolt is fixed to circular brain, sets up the screw thread on the shank of bolt, and the other end is the plane end, and in accommodation process, the mode that the screw was moved to the manual twisting of personnel realizes adjusting, so just can have following problem:

1. the depth of the straight groove and the cross groove at the head part of the screw is shallow, so that the tool is easy to slide out when in operation;

2. the end position is flat head design, and the action point can change in the screw rotation process;

3. and is not beneficial to realizing automatic verification.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a difficult roll-off just does benefit to circuit breaker adjusting screw of automatic check-up during operation.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a circuit breaker adjusting screw, includes the screw body and brain head, the brain head is fixed in one of the screw body and is served, the one end of the screw body is equipped with the drive post dorsad to the brain head, be equipped with drive card edge on the lateral wall of drive post, drive card edge and outside instrument or automatic check-up equipment cooperation to it is rotatory to drive the drive post.

As a further improvement of the present invention, the driving clip is provided with a ridge disposed on the side wall of the driving column.

As a further improvement of the utility model, the driving clip edge is provided with six edges, and is combined into an outer hexagonal structure with the driving column.

As a further improvement of the present invention, the end of the screw body facing away from the brain is provided with a holding structure, and the holding structure holds the center position of the end when the screw body rotates.

As a further improvement of the present invention, the retaining structure is a semispherical structure, and the end face of the semispherical structure is coaxially connected to the end of the screw body and integrally disposed with the screw body to form a round head structure.

The beneficial effects of the utility model, adopted and set up the drive post on the terminal surface of brain and set up the mode that the drive card was followed on the drive post, alright avoid because the groove depth is shallow, the problem of easy roll-off during the instrument operation can do benefit to automatic check-up simultaneously.

Detailed Description

The present invention will be described in further detail with reference to embodiments shown in the drawings.

Referring to fig. 2 to 4, the circuit breaker adjusting screw of this embodiment, including screw body 1 and brain head 2, brain head 2 is fixed in one of screw body 1 and is served, the one end of brain head 2 screw body 1 is equipped with drive post 3 dorsad, be equipped with drive card edge 4 on the lateral wall of drive post 3, drive card edge 4 and outside instrument or the cooperation of automatic check-up equipment to it is rotatory to drive post 3, at the in-process that uses the adjusting screw of this embodiment, only need through outside instrument or automatic check-up equipment cover to drive post 3 on can, it is rotatory to drive post 3 to drive the card edge 4 in step, so compare in the mode that adopts in prior art to set up a word groove and cross groove at the brain head, drive card edge 4 is at the in-process of screwing up, be difficult to appear skidding, and be of being of value to automated operation.

As a modified embodiment, the driving clip edge 4 is an edge arranged on the side wall of the driving column 3, and the firmness of the driving clip edge 4 can be effectively increased by arranging the driving clip edge 4 as an edge.

As an improved specific embodiment, the number of the driving clamping edges 4 is six, and the driving clamping edges and the driving column 3 are combined to form an outer hexagonal structure, so that the head of the adjusting screw of the embodiment is of the outer hexagonal structure, and both an external tool and an automatic checking device can adopt an inner hexagonal structure, so that the adjusting screw of the embodiment can be screwed better, and meanwhile, the adjusting screw is not easy to slip.

As an improved specific embodiment, the end of the screw body 1, which faces away from the brain 2, is provided with a holding structure, and the holding structure holds the central position of the end when the screw body 1 rotates, so that the central position of the end can be effectively held in the rotating process of the screw body 1 through the arrangement of the holding structure, and the rotation adjustment of the screw body 1 is more stable and reliable.

As a modified specific embodiment, the retaining structure is a hemispherical structure, the end face of the hemispherical structure is coaxially connected to the end of the screw body 1 and integrally disposed with the screw body 1 to form a round head structure, and by the arrangement of the hemispherical structure, the central position of the end can be kept unchanged in the rotating process of the screw body 1 by effectively utilizing the spherical structure.

In conclusion, the circuit breaker adjusting screw of this embodiment, through the setting of drive post 3 and drive card edge 4, alright effectual realization drives the effect of brain 2 and screw body 1 rotation, and compares and sets up the mode of slotted groove and cross recess among the prior art, just is difficult to appear the roll-off when the instrument operation, more is applicable to the automation equipment operation simultaneously.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
