Abstract
The utility model discloses a vernier caliper. The vernier caliper comprises a main gauge; the main gauge is provided with a vernier gauge and a depth gauge; the main gauge and the vernier gauge are provided with corresponding external measurement claws and internal measurement claws; and a rectangular upper clamping base, a horseshoe-shaped lower clamping base and a right-angled trapezoid clamping base arranged between the rectangular upper clamping base and the horseshoe-shaped lower clamping base are integrally manufactured so as to form each external measurement claw. The vernier caliper of the utility model is advantageous in structural simplicity, accuracy in measurement and greatly improved work efficiency.
Description
Technical field
The utility model relates to a kind of vernier caliper.
Background technology
Along with the propelling of power grid construction, vacuum switch is more and more.Because vacuum switch manufacturer is different, the measuring position of same switch is different with method, it is larger that measurement data differs, and causes vacuum switch size (open apart from, the over travel) deviation that generation is larger.Therefore when being installed, vacuum switch need the practical operation personnel to detect according to actual conditions.But usual testing vernier caliper can't normally detect for the local detection position that detection space is limited because the outside diameter measuring pawl is oversize.Can cause original qualified switch machine attribute testing defective if can't carry out correct detection to vacuum switch, need the pull bar adjustment, remeasure, increased on foot workload, also may cause the underproof switch mistake of original switch size to be judged as qualified, bury huge hidden danger for the safe and reliable operation of later grid equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of vernier caliper, and it is simple in structure, has correctly greatly improved work efficiency thereby measure.
In order to reach above-mentioned purpose, the technical solution of the utility model is:
A kind of vernier caliper, comprise main scale, be separately installed with vernier scale and pit gauge on main scale, on described main scale and vernier scale, corresponding outer measuring jaw and interior measuring jaw are installed, described outer measuring jaw is by integrally manufactured the forming of right-angled trapezium deck between rectangle upper blocking seat, ungulate lower deck and rectangle upper blocking seat and ungulate lower deck.
Described ungulate lower deck is comprised of trapezoidal fixture block and right-angled trapezium fixture block; The first outer hypotenuse of described trapezoidal fixture block is connected in the same horizontal line with the outer hypotenuse of right-angled trapezium fixture block second; The outer extended line of the interior hypotenuse of described trapezoidal fixture block is α angle setting with the interior right-angle side of right-angled trapezium fixture block, and the α angle is 30-70o angle.
Described α angle is the 60o angle.
The beneficial effects of the utility model are: a kind of vernier caliper that the utility model provides, and simple in structure, adjust for the length of outer measuring jaw, thereby can greatly improve work efficiency by Measurement accuracy.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the outer measuring jaw of the utility model.
Embodiment
As shown in Figure 1 and Figure 2, a kind of vernier caliper of the present embodiment, comprise main scale 1, be separately installed with vernier scale 2 and pit gauge 3 on main scale 1, on described main scale 1 and vernier scale 2, corresponding outer measuring jaw 5 and interior measuring jaw 4 are installed, described outer measuring jaw 5 is by integrally manufactured the forming of right-angled trapezium deck 7 between rectangle upper blocking seat 6, ungulate lower deck 8 and rectangle upper blocking seat 6 and ungulate lower deck 8.Described ungulate lower deck 8 is comprised of trapezoidal fixture block 9 and right-angled trapezium fixture block 10; The first outer hypotenuse 11 of described trapezoidal fixture block 9 is connected in the same horizontal line with the outer hypotenuse 12 of right-angled trapezium fixture block 10 second; The outer extended line of interior hypotenuse 13 of described trapezoidal fixture block 9 and the interior right-angle side 14 of right-angled trapezium fixture block 10 are the α angle and arrange, and the α angle is the 60o angle.5 one of outer measuring jaws are arranged on main scale 1 and with main scale 1 is integrally manufactured and form, and one is arranged on vernier scale 2.Be arranged on outer measuring jaw 5 on vernier scale 2 and concern that due to vernier graduation its width is for shorter than the outer measuring jaw 5 that is arranged on main scale 1.The particular design of its outer measuring jaw 5 also can normally detect for detection space limited local detection position.
A kind of vernier caliper that the present embodiment provides, simple in structure, adjust for the length of outer measuring jaw, thereby can greatly improve work efficiency by Measurement accuracy.
Claims (3)
