Description
Technical field
The utility model relates to a kind of vernier caliper, specifically a kind of special-shaped vernier caliper being convenient for measuring stage shaft length or hole length.
Background technology
Common vernier caliper being and measuring the pit gauge that connects together of vernier when measuring stage shaft length or hole length, because contact area when the pit gauge of common calliper is a kind of elongated measurement measurement bulk measurement is too small when measuring in this way, cause measurement inaccurate.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of special-shaped vernier caliper of the function in conjunction with common calliper and pit gauge.
The utility model is by the following technical programs: a kind of special-shaped vernier caliper, comprises main scale; Described main scale is provided with symmetrical the moving left measuring jaw and move right measuring jaw of sliding along main scale direction; Described moving left on measuring jaw is provided with stationary installation, and move left the inner side of measuring jaw and be provided with inner measuring jaw, opposite side is provided with outer measuring jaw, moves left measuring jaw outer end and is extended with gear chi to both sides; A fixing little measuring jaw is extended in one end of described main scale to side.
It is further: described main scale and move left measuring jaw and the upper and lower size of the measuring jaw that moves right is labeled as English system and the metric system respectively.
Described stationary installation is mounted in the trip bolt moving left measuring jaw side.
Described fixing little measuring jaw end face is oblique angle.
The utility model has two moveable mobile measuring jaws, with an inside and outside measuring claw on each mobile measuring jaw.Extend gear chi in mobile measuring jaw outer end with enlarged contact face, the right-hand member of main scale is more precisely reliable as measurement datum, and the mobile measuring jaw outer termination face of touching is that measuring surface is measured.Main scale installs the position dimension that fixing little measuring jaw can measure deep trench.
The utility model structure is simple, easy to operate, has the function of common calliper and pit gauge simultaneously; The position dimension of deep trench can be measured.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 be the utility model depth measurement or survey high time structural representation;
Structural representation when Fig. 3 is the position dimension of the utility model measurement internal channel.
In figure: 1, main scale; 2, measuring jaw is moved left; 3, move right measuring jaw; 4, stationary installation; 5, fixing little measuring jaw.
Embodiment
Be below a specific embodiment of the present utility model, existing the utility model is described in further detail by reference to the accompanying drawings.
As shown in Figure 1, a kind of special-shaped vernier caliper, the right-hand member of main scale 1 extends a fixing little measuring jaw 5 to side, fixing little measuring jaw 5 end face is oblique angle, can be inserted into the position of the deep trench of measured piece inside to facilitate fixing little measuring jaw 5 end; Main scale 1 is provided with and moves left measuring jaw 2 and the measuring jaw 3 that moves right along the slip of main scale 1 direction, move left measuring jaw 2 and be arranged symmetrically with the measuring jaw 3 that moves right, their primary structure is also identical; Move left the inner side of measuring jaw 2 and be provided with inner measuring jaw, opposite side is provided with outer measuring jaw, moves left measuring jaw 2 outer end and is extended with gear chi to both sides, and when measuring, the mobile measuring jaw outer termination face of touching is measuring surface, and the design of gear chi increases surface of contact, ensures that measurement is more accurate.Main scale 1 and move left measuring jaw 2 and measuring jaw about 3 size that moves right is labeled as English system and the metric system respectively.
As shown in Figure 2, in depth measurement or when surveying high, main scale end face is reference field, and move right measuring jaw 3 right side and gear chi end face are measuring surface, read size by the mark moved right on measuring jaw 3.
As shown in Figure 3, when measuring the position dimension of internal channel, it is inner that main scale end face inserts measured piece, and fixing little measuring jaw 5 end is inserted into the position of the deep trench of measured piece inside.
