Abstract
The utility model provides a vernier caliper which comprises a main scale and a vernier, wherein a first measuring claw is arranged on the veriner, a second measuring claw is arranged on the main scale corresponding to the first measuring claw; and the vernier caliper is characterized in that the second measuring claw is rotatably hinged on the main scale and is provided with a reading window, and the reading window is provided with a pointer; the main scale is further provided with an annular angle dial corresponding to the position of the reading window; and an included angle between the measuring edge of the second measuring claw and the lower edge of the main sale is shown by the matching of the pointer and the annular angle dial. Compared with the prior art, the vernier caliper is rotatably hinged on the main scale by the second measuring claw, and the second measuring claw is rotated so that the measuring edge of the second measuring claw and the lower edge of the main scale form continuous different angles for measuring, and the numerical value of the angle can be directly read from the reading window on the second measuring claw; and the structure is simple, the operation is simple and convenient, and the measurement cost is reduced.
Description
[technical field]
The utility model relates to a kind of vernier caliper, but particularly a kind of vernier caliper of angle measurement degree.
[background technology]
Vernier caliper is a kind of measurer that is mainly used to measure length, interior external diameter and the degree of depth.The vernier caliper of prior art can't take measurement of an angle, therefore when measured workpiece needs to take measurement of an angle simultaneously, necessary use angle survey instrument in addition, come the angle of measuring workpieces such as use amount hornwork or angle block gauge, the result causes in the surveying work practical operation loaded down with trivial details, the survey instrument cost increases, and multiple instrument such as is inconvenient to carry at shortcoming.
[utility model content]
In view of the above problems, it is a kind of simple in structure that the purpose of this utility model is to provide, but the vernier caliper of angle measurement degree easy and simple to handle.
In order to achieve the above object, the utility model provides a kind of vernier caliper, it comprises a main scale and a vernier, this vernier is provided with one first measuring jaw, on this main scale to being provided with one second measuring jaw by first measuring jaw, it is characterized in that: this second measuring jaw rotatably is articulated on this main scale, also is provided with a reading window on this second measuring jaw, also is provided with a pointer on this reading window; On this main scale to should the reading position of window also being provided with an annular angle dish at quarter; The measurement limit of this second measuring jaw and the angle of this main scale lower limb cooperate with this annular angle dish at quarter by this pointer and illustrate.
Preferably, this second measuring jaw rotatably is articulated on this main scale by a fixed rotating shaft.
Preferably, this reading window is semi-circular structure, and this pointer is fixedly arranged on the middle part of this semi-circular structure.
Preferably, also be provided with an active screw on this second measuring jaw, tighten this active screw and this second measuring jaw can be fixed the optional position in rotation.
Compared with prior art, the utility model vernier caliper is by rotatably being articulated in this second measuring jaw on this main scale, rotate this second measuring jaw, the measurement limit that makes this second measuring jaw forms different continuously angles with the lower limb of this main scale and measures, and can be directly this reading window reading angular numerical value from this second measuring jaw, simple in structure, easy and simple to handle, reduced the measurement cost.

[embodiment]
The below describes in further detail better embodiment of the present utility model in conjunction with the accompanying drawings.
Please refer to Fig. 1 to Fig. 4, the utility model provides a kind of vernier caliper, and it comprises a main scale 10 and a vernier 20, and this vernier 20 is provided with one first measuring jaw, on this main scale 10 to being provided with one second measuring jaw 30 by first measuring jaw.
This second measuring jaw 30 rotatably is articulated on this main scale 10 by a fixed rotating shaft 40, also is provided with a semi-circular reading window 60 on this second measuring jaw 30, also is provided with a pointer 70 on the middle position of this semi-circular reading window; On this main scale 10 position that should semi-circular reading window 60 also is provided with half annular angle and coils 61 quarter; The angle of the measurement limit 31 of this second measuring jaw and the lower limb 11 of this main scale can coil 61 quarter by this pointer 70 and this semi-circular angle and cooperate and illustrate.
Also be provided with an active screw 50 on this second measuring jaw 30, tighten this active screw 50 and this second measuring jaw 30 can be fixed the optional position in rotation.
When the utility model vernier caliper was applied to measure length, this second measuring jaw 30 at right angles, was tightened this active screw 50 and is made this second measuring jaw 30 fixing between the measurement limit 31 of this second measuring jaw and the lower limb 11 of this main scale perpendicular to this main scale 10.
When the utility model vernier caliper is applied to the angle of measuring workpieces, the lower limb 11 of this main scale 10 is fitted in one side of the angle of measured workpiece, unscrew this active screw 50, clockwise or rotate counterclockwise this second measuring jaw 30, make the measurement limit 31 of this second measuring jaw fit in the another side of the angle of this measured workpiece.Be a angle between the lower limb 11 of the measurement limit 31 of this second measuring jaw and this main scale 10 at this moment, be the angle value of measured workpiece, this pointer 70 is instructed in the respective angles value position of this angle dial 61, tightens this active screw 50 and makes this second measuring jaw 30 fixing, can carry out reading.
Compared with prior art, the utility model vernier caliper is by rotatably being articulated in this second measuring jaw on this main scale, rotate this second measuring jaw, the measurement limit that makes this second measuring jaw forms different continuously angles with the lower limb of this main scale and measures, and can be directly this reading window reading angular numerical value from this second measuring jaw, simple in structure, easy and simple to handle, reduced the measurement cost.
Be pointed out that; the utility model is not limited to above-mentioned embodiment; any simple modification, equivalent variations and modification that any those skilled in the art do the foregoing description based on technical solutions of the utility model all fall in the protection domain of the present utility model.
