Embodiment

Embodiment of the present utility model can further specify by the following detailed description:

With reference to figure 1, of the present utility model poor clearance ruler comprises blade 1, and the one side of blade 1 indicates the table at quarter, and blade 1 is made up of ruler section 10 and awl chi section 11, awl chi section 11 is extended from the end with respect to 0 scale of ruler section 10, and the breadth extreme of awl chi section 11 equals the width of ruler section 10.Also comprise vernier 2, this vernier 2 is similar with the vernier on the vernier caliper commonly used, comes the reading of accurate blade 1 by its, for example, in the utility model, after vernier 2 can make reading be accurate to radix point one; Vernier 2 can slide by relative blade 1 along the length direction of blade 1.

With reference to figure 1 and Fig. 2, the slip of vernier 2 on blade 1 realizes by chi frame 3, chi frame 3 comprises body 31 and the end difference 34 that extends from body, outstanding position at end difference 34 offers the rib-loop hole, vernier 2 is fixed on the end difference 34 by

screw

5, and 1 of blade is clamped between vernier 2 and the body 31; The ladder position 34 of chi frame 3 is positioned at the top of blade 1, and described end difference 34 is provided with the screw rod 6 that penetrates end difference 34 towards blade 1 direction, and described screw rod 6 is connected on the blade 1, is provided with pad at the position of these screw rod 6 butts usually, prevents that screw rod from damaging blade.Mode by boss and groove fit between body 31 and the vernier 2, make at vernier 2 when blade 1 length direction slides, the degree of freedom of restriction vernier 2 on blade 1 Width, make the reading of vernier accurate, referring to Fig. 2 and Fig. 3, body 31 is provided with boss 33, and the back side correspondence of blade 1 is provided with groove 12, and boss 33 can slide in groove 12; By with upper type, vernier 2 can be limited along the degree of freedom of blade 1 width and thickness direction, and vernier 2 can slide along blade 1 length direction.

As Fig. 2, the end distance that boss 33 is relative with 0 scale of ruler section 10 is L1 from the distance of adjacent chi frame end face, as Fig. 3, the distance of an end distance from awl chi section 11 tips that groove 11 is relative with 0 scale of ruler section 10 is L2, it is 0 o'clock scale that the tip of awl chi section 11 corresponds to the gap, when making vernier 2 slide into this 0 scale, the end face of vernier 2 is no more than the tip of main scale section 11, must be set to L1=L2.

As Fig. 2, be provided with benchmark portion 4 at the end adjacent of chi frame 3 with vernier 0 scale, this benchmark portion 4 extends from the end of chi frame 3, and is provided with reference field 41 thereon; With reference to figure 1, in the face difference clearance ruler that assembles, distance between reference field 41 and vernier 0 scale equals the end face 101 of ruler section 10 and the distance between ruler section 0 scale, above reference field 41 is interpreted as, the face that contacts with face to be measured during measurement face difference specifically will be set forth in the user mode below, usually, reference field 41 is the same with the end face 101 of ruler section 10, is vertical face.

The measurement face difference of the utility model face difference clearance ruler and the method in gap are as follows:

With reference to figure 4a, be depicted as the synoptic diagram of face difference measurements, face to be measured is A face and B face, ruler section end face 101 and reference field 41 respectively with A face and B face in one contact, the distance of ruler section end face 101 and reference field 41 is the distance between A face and the B face, the numerical value of this distance is read by ruler section 10 and vernier 2, referring to the partial enlarged drawing of Fig. 4 b, in the present embodiment, this numerical value is 10.30mm, that is, the face difference is 10.30mm (behind the radix point second read for estimating) between A face and the B face.
