Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people All other embodiments that member is obtained, broadly fall into the scope of this utility model protection.

As shown in Figure 1 and Figure 2, a kind of slide gauge, including main scale 1,4, two internal measure-hand 2 of vernier With two external pelivimetry pawls 3, described internal measure-hand 2 includes internal measure-hand body 21 and internal measure-hand claw 22, Described internal measure-hand claw 22 is fixedly connected on internal measure-hand body 21 by least one screw；Described Internal measure-hand body 21 includes that base portion 211, described base portion 211 are provided with L-shaped mounting plane, Base portion 211 outwardly formation limiting section 212, described internal measure-hand pawl described at the mounting plane of this L-type Portion 22 is provided with the draw-in groove 221 matched with this limiting section 212, when described internal measure-hand claw 22 is installed Time on internal measure-hand body 21, the limiting section 212 on described internal measure-hand body 21 is fastened on described interior In the draw-in groove 221 of measuring claw claw 22, when described internal measure-hand claw 22 is arranged on internal measure-hand body Time on 21, the first datum level 213 on described internal measure-hand body 21 and described internal measure-hand claw 22 On the second datum level 222 be generally aligned in the same plane.

Also include that the height value of described limiting section 212 is equal with the vertical height value of described draw-in groove 221.

Also include that the one-tenth-value thickness 1/10 of described limiting section 212 is equal with the groove width value of described draw-in groove 221.

Also include that the length value of described limiting section 212 is equal with the groove depth value of described draw-in groove 221.

Also include at graduation mark, being provided with magnifier 5 on described vernier 4；Described magnifier 5 includes installing rack 51, described installing rack 51 is provided with convex lens 52.So facilitate reading, it is to avoid some user are due to eye The problem of the eyeball number of degrees, does not sees the measurement numerical value that Chu is concrete.

Also include that described external pelivimetry pawl 3 includes external pelivimetry pawl body 31 and external pelivimetry pawl claw 32, described outside Measuring claw claw 32 is fixedly connected on described external pelivimetry pawl body 31 by screw；Described external pelivimetry pawl is originally Body 31 is provided with concavity breach 311, and described external pelivimetry pawl claw 32 is placed at described concavity breach 311. Described external pelivimetry pawl claw 32 uses wolfram steel or high-carbon steel to make.Can by change external pelivimetry pawl claw 32, After solving long-time use external pelivimetry pawl claw 32 wear and tear and cause measure the problem that precision declines.

Understand technique scheme of the present utility model for convenience, below by way of in specifically used mode to this The technique scheme of utility model is described in detail.

When described internal measure-hand claw 22 is installed on described internal measure-hand body 21, described internal measure-hand is originally Limiting section 212 on body 21 to be stuck in the draw-in groove 221 on described internal measure-hand claw 22, the most permissible Described internal measure-hand claw 22 is carried out a location, the most described internal measure-hand claw 22 and limiting section The screwed hole being easily installed screw it is equipped with, so by screw lock, locking after installation puts in place on 212 The first datum level 213 on rear described internal measure-hand body 21 and second on described internal measure-hand claw 22 Datum level 222 is generally aligned in the same plane, and such internal measure-hand 2 can make zero, and prevents two internal measure-hand 2 Between there is bigger gap.

It is equipped with the various sizes of internal measure-hand claw 22 of many sets, at the inside diameter measurement carrying out different depth requirement Time, by unclamping the screw being fastenedly connected internal measure-hand claw 22, carry out the internal measure-hand pawl of corresponding size The replacing in portion 22, then locks and just may be used.

Embodiment described above only have expressed preferred implementation of the present utility model, its describe more concrete and In detail, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, For the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to make Some deformation, improving and substitute, these broadly fall into protection domain of the present utility model.Therefore, this practicality is new The protection domain of type patent should be as the criterion with claims.
