Abstract
The utility model relates to a kind of vernier caliper, comprise a L-shaped chi frame, be primarily characterized in that and described chi frame measured angular is provided with the first extending ruler plate, the first described extending ruler plate is located mutually by screw and measured angular, described chi frame is also set with moveable measured angular, described moveable measured angular is provided with the second extending ruler plate, it is fixed by screw.When the length of measured angular is inadequate measuring large diameter object for vernier caliper, just the screw of the first extending ruler plate can be unscrewed, first extending ruler plate is pulled out and is tightening fixed screw, make measured angular elongated, just can measure the diameter of large diameter object accurately, and the second extending ruler plate is well used for making to the diameter of measured angular the feature that changes.
Description
Technical field
The utility model relates to a kind of vernier caliper.
Background technology
A kind of measuring tool of the vernier caliper amount of being used to dimension of object, existing vernier caliper comprises a fixing L-shaped chi frame, also comprise a moveable measured angular be sleeved on L shape chi frame, and measured angular on chi frame and moveable measured angular are all that tool is figurate, can not change, so when measurement exceedes the major diameter object of measured angular length, because the length of measured angular is inadequate, can exist and measure inaccurate problem, the utility model well solves existingly exists technical matters.
Summary of the invention
The utility model provides a kind of vernier caliper, it mainly solves the measured angular of existing vernier caliper and moveable measured angular is all that tool is figurate, can not change, so when measurement exceedes the major diameter object of measured angular length, because the length of measured angular is inadequate, can exists and measure inaccurate technical matters.
A kind of vernier caliper of the present utility model, comprise a L-shaped chi frame, be primarily characterized in that and described chi frame measured angular is provided with the first extending ruler plate, the first described extending ruler plate is located mutually by screw and measured angular, described chi frame is also set with moveable measured angular, described moveable measured angular is provided with the second extending ruler plate, it is fixed by screw.
The utility model provides a kind of vernier caliper, when the length of measured angular is inadequate measuring large diameter object for vernier caliper, just the screw of the first extending ruler plate can be unscrewed, first extending ruler plate is pulled out and is tightening fixed screw, make measured angular elongated, just can measure the diameter of large diameter object accurately, and the second extending ruler plate is well used for making to the diameter of measured angular the feature that changes.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Mark in figure: 1-chi frame: 2-first extending ruler plate: the moveable measured angular of 3-screw: 4-: 5-second extending ruler plate.
Embodiment
Understand for the ease of those of ordinary skill in the art and implement the utility model, and by reference to the accompanying drawings the technical solution of the utility model being described in further detail.
Embodiment: as shown in Figure 1, a kind of vernier caliper of this example, comprise a L-shaped chi frame (1), be primarily characterized in that and described chi frame (1) measured angular is provided with the first extending ruler plate (2), the first described extending ruler plate (2) is located with measured angular mutually by screw (3), described chi frame (1) is also set with moveable measured angular (4), described moveable measured angular (4) is provided with the second extending ruler plate (5), it is fixed by screw (3).During use, when the length of measured angular is inadequate measuring large diameter object for vernier caliper, just the screw of the first extending ruler plate can be unscrewed, first extending ruler plate is pulled out and is tightening fixed screw, make measured angular elongated, just can measure the diameter of large diameter object accurately, and the second extending ruler plate is well used for making to the diameter of measured angular the feature that changes.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
