Embodiment:Scratch resistant 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 slid 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 figure 1, scratch resistant 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 stretch into hole, bottom is set as more sharp shape, and to ensure accurate, the bottom measured
Clamping part be line style.Internal measure-hand 4 then dedicated for the internal diameter in measure geometry shape hole, therefore 4 global design of internal measure-hand at compared with
Be sharp shape to facilitate it to be inserted into geometric form hole, the clamping part of internal measure-hand 4 be linear structure and its towards 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 figure 1, is slid along its length away from the one side of main scale mark 11 in main scale 1 and be connected with depthometer 5, depth
Ruler 5 is fixedly connected with vernier scale 2.
With reference to figure 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 human hand
When holding main scale 1 and measuring, thumb is typically toward 3 side of exterior measuring measuring jaw, Gu Ding wheels 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.1, after measuring the data of needs, vernier scale 2 is touched outside people's will in order to prevent, causes error in reading,
Tapped through hole is offered in the side of vernier scale 2, trip bolt 22 is correspondingly provided in tapped through hole, after having measured data,
Vernier scale 2 can be fixed on current location by twisting trip bolt 22, avoided to a certain extent caused by surprisingly touching
Error in reading.
It is especially right in order to avoid exterior measuring measuring jaw 3 causes to scratch in its bottom end when measuring workpiece to workpiece with reference to figure 1 and Fig. 2

Ball 7 protrudes from the bottom surface of exterior measuring measuring jaw 3, and it is rolling friction to be contacted in this way with workpiece when the bottom end of exterior measuring measuring jaw 3, reduces exterior measuring
Measuring jaw 3 scratches the possibility of workpiece.
Referring to figs. 2 and 3, it is contemplated that when measuring the larger workpiece of profile outer diameter, exterior measuring measuring jaw 3 not enough leads to nothing because of length
Method measures its outer diameter size, therefore fixed plate 12 is respectively fixed on main scale 1 and vernier scale 2, and two fixed plates 12 are arranged in parallel,
The sliding slot 31 coordinated with fixed plate 12 is equipped on outer measuring claw 3, sliding slot 31 is opposite with fixed plate 12 to be slided so that exterior measuring measuring jaw
3 can slide along 12 length direction of fixed plate to adjust entire length.
Referring to figs. 2 and 3, limited position mechanism 6 is installed in the side of outer measuring claw 3 away from each other, position-limit mechanism 6 is so that outer
Opposing fixed plate 12 is fixed after measuring claw 3 is moved to suitable position.It is equipped with and communicates therewith perpendicular to sliding slot 31 on outer measuring claw 3
Through-hole 32, position-limit mechanism 6 includes being arranged in gag lever post 61 and elastic component 63 in through-hole 32, and elastic component 63 connects gag lever post 61
With exterior measuring measuring jaw 3, elastic component 63 applies the power moved to fixed plate 12 to gag lever post 61.
One end that gag lever post 61 is connect with fixed plate 12 is tapered end 611, and tapered end 611 is engaged with tooth socket 121, gag lever post
61 other end exposes outer in through-hole 32 and is equipped with pull handle 612.It is installed with baffle ring 62 in the one end of through-hole 32 far from sliding slot 31,
It is arranged on gag lever post 61 and is fixed with pressure ring 64, elastic component 63 can be spring, and spring is set between baffle ring 62 and pressure ring 64
On gag lever post 61.
The application method of the scratch resistant vernier caliper is as follows:
The bottom end of exterior measuring measuring jaw 3 is bonded with workpiece surface, then moving cursor ruler 2 is so that between two exterior measuring measuring jaws 3
Distance be gradually decrease to be bonded with workpiece measured surface.Due to exterior measuring measuring jaw 3 and workpiece surface rolling friction, with vernier scale 2
The bottom end of the exterior measuring measuring jaw 3 of connection will not be caused to scratch in moving process to workpiece surface, is reduced nonproductive factors and is caused
Waste product.
When the profile outer diameter of measured workpiece is larger, the pull handle 612 of gag lever post 61, mobile 3 edge of exterior measuring measuring jaw are pulled out
It the movement of fixed plate 12 and adjusts entire length, when the entire length of exterior measuring measuring jaw 3 is suitable, unclamp pull handle 612, gag lever post 61 exists
It is clamped again with fixed plate 12 under the action of elastic component 63 so that exterior measuring measuring jaw 3 is stablized with fixed plate 12 to be fixed, and raising measures steady
It is qualitative.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
