Abstract

The utility model provides calipers, which can simultaneously have the functions of measuring and writing and can be conveniently carried. A main scale is a hollow cylindrical body, wherein the graduation surface of which is a plane; an auxiliary scale has a shape matched with the main scale, and is clamped and tightly abutted on the outer wall of the main scale. A depth scale is installed on the inner wall of the auxiliary scale, and is parallel to the main scale. The outer wall of the main scale is provided with a groove which corresponds to the position, the shape and the size of the depth scale. When the auxiliary scale moves on the main scale, the depth scale is kept in the groove and moves along the auxiliary scale. A pen is arranged in a cavity of the main scale; a pen head extends out of the cavity of the main scale. The depth scale can be folded to shorten length; outer measuring jaws of the main scale and the auxiliary scale can be folded towards the positions of inner measuring jaws; the outer wall position at the back side of the auxiliary scale is provided with a hook. The utility model has simple structure, and is capable of simultaneously providing calipers and the pen for users to conveniently measure and write; the portable multifunction calipers can be hung by the hook on places such as clothes pockets, etc., where the calipers are easy to hang and placement and carryover are made to be more convenient.

Description

A kind of portable multi-function slide calliper rule

Belong to technical field

The utility model belongs to a kind of survey instrument, and especially a kind of having concurrently measured and writing function slide calliper rule.

Technical background

Present widely used slide calliper rule generally are made up of main scale, secondary chi, pit gauge, inner measuring jaw, outer measuring jaw.Secondary chi length is less than main scale length, and the shape of secondary chi for being complementary with main scale engages and be close to the main scale outer wall, and secondary chi is provided with trip bolt, can secondary chi is fixing on main scale when secondary chi moves into place on main scale.Pit gauge is installed in the inwall of secondary chi and parallel with main scale, the main scale outer wall be provided with one with pit gauge position and the corresponding groove of shape size, when mobile, pit gauge remains in this groove and with secondary chi and moves secondary chi on main scale.These slide calliper rule only have single measurement function, and usually need simultaneously to write measuring in actual the use, and at this moment survey crew needs carry in addition one-pen when carrying slide calliper rule, take up one's pen after with the kind of calliper data again and write, and use inconvenience.

Summary of the invention

The purpose of this utility model provides a kind ofly can have measurement, writing function simultaneously, and carries slide calliper rule more easily.

For achieving the above object, the utility model is achieved through the following technical solutions.

A kind of portable multi-function slide calliper rule of the present utility model comprise main scale 1, secondary chi 2, pit gauge 3, outer measuring jaw 4 and inner measuring jaw 5, and secondary chi 2 length are less than main scale 1 length.Described main scale 1 is the hollow cylinder on plane for the scale face, and the shape of secondary chi 2 for being complementary with main scale 1 engages and be close to main scale 1 outer wall, and secondary chi 2 is provided with trip bolt 6; Pit gauge 3 is installed in the inwall of secondary chi 2 and parallel with main scale 1; Main scale 1 outer wall be provided with one with the corresponding groove of pit gauge 3 positions and shape size, when mobile, pit gauge 3 remains in this groove and with secondary chi 2 and moves secondary chi 2 on main scale 1; Be provided with one-pen 7 in the cavity of main scale 1, nib is exposed cavity.

Flexibly connect one identical with main scale shape size, length greater than the extension chi 8 that exposes main scale cavity nib in that main scale 1 is terminal, the nib of described pen 7 is inserted in the cavity of extending chi 8, and the plane of extending chi 8 indicates scale, and scale continues the scale of main scale 1 end.Extension chi 8 can be used as the part of main scale 1 and carries out survey measurements, enlarges and measures range, and can be used as pen cap protection nib.When needs are write, will extend chi 8 and separate with main scale 1, expose nib and can write.

The front portion of stretching out secondary chi part at described pit gauge 3 chi bars is provided with pit gauge folding position 10, makes the pit gauge length can folds shorten.The pit gauge extension is longer than the nib of exposing and will be hindered and write when measuring, at this moment can shorten the pit gauge extension elongation by moving sets chi 2, and can eliminate influence, thereby realize not only can writing but also not influencing the reading that slide calliper rule have been measured by the folded depth chi to nib.

At the outer wall position at described secondary chi 2 back sides one hook 9 is installed.

Measuring jaw folding position 11 outside the outer measuring jaw 4 of described main scale 1 and secondary chi 2 is provided with can fold outer measuring jaw 4 to inner measuring jaw 5 positions.

The utility model is simple in structure, and is aesthetic in appearance, can be the user slide calliper rule and pen are provided simultaneously, is convenient for measuring and writes.Extend chi and have the effect of measuring the blade and the pen cap concurrently, can enlarge and measure range and protection nib.Outer measuring jaw is folding to the inner measuring jaw position, can reduce the slide calliper rule volume, use the hook that is installed in the secondary chi back side outer wall slide calliper rule can be hung over the place that pocket etc. is easy to hang, make and place and carry more convenient.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in more detail.

As shown in Figure 1, 2, 3, described main scale 1 is that plane, the back side are the hollow cylinders of cambered surface for the scale face, secondary chi 2 blocks the upper/lower terminal of main scale 1 scale face respectively with upper and lower two screens, secondary chi 2 back sides are the cambered surfaces that are complementary with main scale 1 shape, whole secondary chi 2 engagings also are close to main scale 1 outer wall, secondary chi 2 can move on main scale 1, also is provided with trip bolt 6 on the secondary chi 2, can secondary chi be fixed by trip bolt 6 when secondary chi 2 moves into place.Pit gauge 3 is installed in the arc inner wall medium height position at secondary chi 2 back sides and parallel with main scale 1, arc outer wall at main scale 1 back side is provided with one and pit gauge 3 positions and the corresponding groove of shape size, when mobile, pit gauge 3 remains in this groove and with secondary chi 2 and moves secondary chi 2 on main scale 1.The cavity internal fixation one-pen 7 of main scale 1, nib is stretched out the main scale cavity.
