Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Wherein identical components are presented with like reference characters.It should be noted that word used in the following description
Language "front", "rear", "left", "right", "up" and "down" refer to the direction in attached drawing, word " bottom surface " and " top surface ", "inner" and
"outside" refers respectively to the direction towards or away from geometric center of specific component.
Embodiment: durable vernier caliper, as shown in Figure 1, including main scale 1, main scale 1 is the flat structure of strip, in master
The side of ruler 1 is provided along its length main scale mark 11.Main scale 1 is head close to one end of zero graduation line, and the other end is then
Tail portion.
It is fitted on main scale 1 and is arranged with one section of vernier scale 2, main scale 1 passes through vernier scale 2 and slides with it and connect.In vernier scale 2
Bottom side be provided along its length subscale mark 21, vernier scale 2 is head close to one end of zero graduation line, and the other end is then tail
Portion.
With reference to Fig. 1, durable vernier caliper further include a pair of of exterior measuring measuring jaw 3 for measuring outer diameter and end face spacing and
A pair of of internal measure-hand 4 for measure geometry shape hole internal diameter.A pair of of exterior measuring measuring jaw 3 is integrally formed at main scale 1 and vernier respectively
The side on 2 its head of ruler, a pair of of internal measure-hand 4 are integrally formed at the other side on 2 its head of main scale 1 and vernier scale respectively.
Exterior measuring measuring jaw 3 is claw type slab construction, and the opposite side of two outer measuring jaws is clamping part.In measured hole internal diameter,
To enable exterior measuring measuring jaw 3 easily to protrude into hole, bottom is set as more sharp shape, and accurate, the bottom to guarantee measurement
Clamping part be line style.Internal measure-hand 4 then dedicated for the internal diameter in measure geometry shape hole, therefore 4 whole design of internal measure-hand at compared with
It is sharp shape to facilitate it to be inserted into geometric form hole, the clamping part of internal measure-hand 4 is linear structure and its direction and exterior measuring
The direction of the clamping part of measuring jaw 3 is opposite.
When vernier scale 2 slides to the dead-center position of main scale 1, the clamping part of two exterior measuring measuring jaws 3 will be close to mutually, in two
The clamping part of measuring claw 4 staggeredly adjacent will paste.
With reference to Fig. 1, is slid along its length in main scale 1 away from the one side of main scale mark 11 and be connected with depthometer 5, depth
Ruler 5 is fixedly connected with vernier scale 2.
With reference to Fig. 1, vernier scale 2 is stirred for convenience of thumb, top wheel 23 has been wholely set on vernier scale 2, it is contemplated that manpower
When holding main scale 1 and measuring, thumb is typically toward 3 side of exterior measuring measuring jaw, Gu Ding wheel 23 be also disposed on vernier scale 2 have it is outer
A distance is separated on the position of 3 side of measuring claw and between exterior measuring measuring jaw 3, and in order to increase rubbing between thumb and top wheel 23
It wipes to be more convenient its use, top wheel 23 is designed to the structure with the arcwall face of anti-skid chequer.
Referring to Fig. 2 and Fig. 3, after measuring the data of needs, vernier scale 2 is touched outside people's will in order to prevent, causes to read
Error offers tapped through hole in the side of vernier scale 2, fastening screw 22 is correspondingly provided in tapped through hole, has measured number
According to rear, vernier scale 2 can be fixed on current location by twisting fastening screw 22, be avoided to a certain extent because unexpected touch is made
At error in reading.
Referring to figs. 2 and 3, since exterior measuring measuring jaw 3 causes contact surface to be worn often in contact with object being measured, two such
The distance between exterior measuring measuring jaw 3 changes, and causes the inside of exterior measuring measuring jaw 3 and the zero graduation on main scale 1 to deviate, so that measurement
Data inaccuracy.Therefore, the wear plate 6 of strip, wear plate 6 are respectively fixed with inwardly in the phase of a pair of of exterior measuring measuring jaw 3
It can be by abrasion-resistant stee processing and fabricating, hardness and wearability with higher.
The holding tank 31 for placing wear plate 6, the width and wear plate of holding tank 31 are equipped in the inside of outer measuring claw 3
6 it is of same size, the length of holding tank 31 is greater than the length of wear plate 6, and wear plate 6 is smoothly put into holding tank to facilitate
In 31.
Referring to figs. 2 and 3, at least one threaded hole 32, this implementation are equipped in the inside that outer measuring claw 3 is located at holding tank 31
It is three in example, counter sink 62 corresponding with threaded hole 32 is equipped on wear plate 6, wear plate 6 and exterior measuring measuring jaw 3 passes through screw
63, which are screwed after counter sink 62 with threaded hole 32, connect.
The end face that makes wear plate 6 and zero graduation line pair main scale 1 on are put into holding tank 31 for the ease of wear plate 6
Together, it is equipped with locating slot 311 in the bottom end of holding tank 31, the positioning end cooperated with locating slot 311 is equipped in the end of wear plate 6
61, when positioning end 61 is completely inserted into locating slot 311, counter sink 62 could be aligned with threaded hole 32, when tightening fixed spiral shell
After nail 63, the end face of wear plate 6 is fixed on predetermined position.Positioning end 61 can be as upper thick and lower thin tapered end, aspect positioning
End 61 is smoothly inserted into locating slot 311.
The maintaining method of the durable vernier caliper is as follows:
Periodically vernier caliper is calibrated, when the appearance of the zero-bit of the end face for wear plate 6 occur and main scale mark 11 is larger
Deviation and when can not be calibrated using classical calibration fashion, moving cursor ruler 2 make two exterior measuring measuring jaws 3 away from each other to there is foot
Enough spaces use screwdriver.Screw 63 will be unscrewed using screwdriver, then mobile former wear plate 6 takes out from holding tank 31, more
The wear plate 6 that renews simultaneously tightens screw 63 again, is calibrated again, so that vernier caliper remains to continue to use, extends
Service life.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
