Abstract
The utility model discloses a foreign steamer diameter of inner circle examines utensil, which comprises a base. Through the fixed dial plate that is equipped with of fastening nut on the base, the dial plate lower extreme passes through spring and lever connection, and movable gauge head is installed to the lever right -hand member, and activity gauge head top is equipped with fixed gauge head, and fixed gauge head is fixed to be located on the base, activity gauge head and fixed gauge head are the sphere. The utility model discloses simple structure, reasonable in design, convenient to use, beat reading through the pointer can record the difference of measured piece and standard component to record measured piece diameter of the inner circle, measuring result is accurate.
Description
Technical field
The utility model relates to surveying instrument field, specifically a kind of foreign steamer inner circle diameter detector.
Background technology
In study or in producing, often run into the situation needing to know circular diameter in foreign steamer, but directly can not measure the cubing of circular diameter in foreign steamer at present.General employing measures the method acquisition bottom clearance value of correlation parameter again by calculating, and this method wastes time and energy, and difficulty is high.
Utility model content
The purpose of this utility model is to provide a kind of foreign steamer inner circle diameter detector, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of foreign steamer inner circle diameter detector, comprises pedestal; Described pedestal is fixed with dial plate by clamp nut; Dial plate lower end is connected with lever by spring, and lever right-hand member is provided with movable gauge head, is provided with fixing gauge head above movable gauge head, and fixing gauge head is fixed on pedestal.
As further program of the utility model: described movable gauge head and fixing gauge head are spherical.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, easy to use, can be recorded the difference of measured piece and standard component by the beat reading of pointer, thus record circular diameter in measured piece, measurement result is accurate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-pedestal, 2-dial plate, 3-clamp nut, 4-lever, the movable gauge head of 5-, 6-measured piece, 7-fixes gauge head.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of foreign steamer inner circle diameter detector, comprises pedestal 1; Described pedestal 1 is fixed with dial plate 2 by clamp nut 3; Dial plate 2 lower end is connected with lever 4 by spring, and lever 4 right-hand member is provided with movable gauge head 5, is provided with fixing gauge head 7 above movable gauge head 5, and fixing gauge head 7 is fixed on pedestal 1.
Further, movable gauge head 5 described in the utility model and fixing gauge head 7 are spherical.
The principle of work of utility model is:
During measurement, first the standard component of measured piece 6 is contained in cubing and cubing is calibrated, make the pointer of dial plate 2 aim at 0 groove; Then take off standard component, measured piece 6 is contained in cubing, the difference of measured piece 6 and standard component can be recorded by the beat reading of pointer, thus record circular diameter in measured piece.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this instructions is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should by instructions integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
