Abstract
The utility model provides an internal (external) vernier caliper used for measurement, comprising a caliper frame, a caliper body with a main caliper, a fastening screw, a pressing sheet with an auxiliary caliper, a caliper frame, a shaft pin and a measurement head; the technical key point is that the two ends of the caliper body and the caliper frame are respectively connected with the caliper frame symmetrically; the crossing position of the two caliper frames is movably connected with the shaft pin so that the two caliper frames are connected to be a V-shaped or an X-shaped caliper; the other end of the caliper frame is provided with a measurement head which is designed according to the similar ratio principle of triangle. The internal (external) vernier caliper has the advantages of simple and compact structure, wide measurement range, high measurement precision, convenient carrying, long service life, and the like.
Description
Technical field
The utility model belongs to the measurer technical field, specifically a kind of clamp and vernier caliper is become external diameter vernier caliper in the measuring of one.
Background technology
Present widely used vernier caliper, part all comes with some shortcomings: 1. most of vernier caliper structures are numerous and diverse, portably use equal inconvenience.2. measuring head is a cusp, during application, not only scratches the surface of measured workpiece easily, and quick-wearing very itself, thus the precision of losing, so using value is very little.2. function singleness, interior vernier caliper can only be measured inside dimension, and outer vernier caliper can only be measured outside dimension, thereby has limited its range of application greatly.
The utility model content
The purpose of this utility model provides a kind of vernier caliper simple and compact for structure of measuring external diameter and interior gauge structure interior external diameter.
The purpose that the utility model is is achieved in that it comprises compressing tablet, chi frame, pivot pin, the measuring head of the secondary chi of blade, clench nail, band of chi frame, a band main scale, its technical essential be at the two ends of blade and chi frame respectively symmetry be connected to a chi frame, be connected with a pivot pin two chi frame intersection area work, make two chi framves connect into " V " shape or " X " shape clamp, be provided with a measuring head at chi frame one end.
Above-mentioned measuring head is circular-arc measuring head, in order to avoid the measuring head of cusp scratches the surface of measured workpiece, and easy to wear, thus the precision of losing reduces actual application value.
The utility model makes the center of circle O of circular arc owing to being arc-shaped surface with measuring head
1Be positioned at the center of circle O of blade chi frame and chi frame connecting portion
2Center of circle O with pivot pin
3The extended line of line of centres on, (as depicted in figs. 1 and 2).Utilize leg-of-mutton ratio of similitude principle measured value.Have simple and practical, characteristics such as measurement range is wide.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
First kind of embodiment structural representation of Fig. 1 the utility model.
Second kind of embodiment structural representation of Fig. 2 wood utility model.
Wherein: 1, chi frame; 2, the blade of band main scale; 3, clench nail; 4, with the compressing tablet of secondary chi; 5, chi frame; 6, pivot pin; 7, measuring head.
To be described in further detail utility model by example below, but following example only is a wherein example of the present utility model the rights protection scope of not representing the utility model and being limited.
Embodiment
Fig. 1 is shown in Figure 2.The inside and outside vernier caliper of this measurement, it comprises blade 2, clench nail 3, the compressing tablet 4 with secondary chi, chi frame 5, pivot pin 6, the measuring head 7 of chi frame 1, a band main scale, its technical essential be at the two ends of blade 2 and chi frame 5 respectively symmetry be connected to a chi frame 1, be connected with a pivot pin 6 two chi frame intersection area work, make two chi framves 1 connect into " V " shape or " X " shape clamp, be provided with a measuring head 7 at the chi frame other end; This chi frame 1 and circular-arc measuring head 6 have been formed the measuring junction of clamp structures; Vernier caliper on the chi frame 1 is the reading end.During measurement, individual circular arc, O are arranged respectively on each measuring head 7
1Point is the center of circle of this circular arc.The outer section of its circular arc is used to measure inside dimension, and the circular arc inner segment is used to measure outside dimension.
Its using method is: only need this vernier caliper is placed the measured piece measured position, hand is held the connecting portion alive at blade and chi frame two ends, and gauge head is contacted with tested and tested position, and can read measured size this moment at the reading end.Can on measured piece, read size, also can it be locked, read size to other place with clench nail.
It should be noted that at last: the above embodiment only is a preferred implementation of the present utility model.Therefore, those of ordinary skill in the art is to be understood that, under the prerequisite that does not break away from the principle of the invention, need not the technical characterictic that the process creative work just can be associated, can also make some modification or improvement, obviously these variations all are considered as equivalent feature, all should be encompassed in the middle of the claim scope of the present utility model.
