Specific embodiment
Below in conjunction with attached drawing and technical solution, the specific embodiment further illustrated the present invention.
A kind of adjustable chord length diameter measurer, including locating detent 1, sliding sleeve 2, apparatus body 3, connector 4, digital display meter 5, clamp screw Nail 6 and annular knurl thin nut 7;
The section of the apparatus body 3 is equipped with symmetrical positioning slide opening and connector mounting hole, and connector mounting hole is located at two Among symmetrical positioning slide opening, scale mark is carved in apparatus body 3;
The locating detent 1 and sliding sleeve 2 are coordinated using transition, are installed in positioning slide opening, and pass through annular knurl thin nut 7 Fixed limiting;Described 2 one end of sliding sleeve is equipped with positive stop lug boss, is limited in apparatus body 3, and sliding sleeve 2 is used with positioning slide opening Clearance fit;The section of the locating detent 1 is the T-shape structure of triangular front end, i.e., operating point is conical surface vertex;Locating detent 1 shank portion and 2 clearance fit of sliding sleeve, the shank portion than 1 end of locating detent is thick, and the end of locating detent 1 is equipped with outer Screw thread uses thread fitting with annular knurl thin nut 7;When locating detent 1, sliding sleeve 2 slide into target position in apparatus body 3 simultaneously It puts, applies active force by screwing annular knurl thin nut 7,1 horizontal position of locating detent is positioned;
The connector 4, using being interference fitted, realizes the locating clip to digital display meter 5 with the connector mounting hole in apparatus body 3 Tightly, connector 4 is gap-matched with digital display meter 5;The connector 4 is equipped with screw hole, and holding screw 6 is using threaded connection; Digital display meter 5 is clamped by tightening holding screw 6, so as to adjust 5 measurement head upright position of digital display meter.
Further, the sliding sleeve 2 realizes horizontal slip in the device, by the way of plane-plane contact slip, contact The size in face and surface smoothness requirements are very high;Sliding sleeve 2 has auxiliary direction-pointing function simultaneously, it is desirable that pointer shape is accurate;It is sliding Dynamic set 2 is easy to wear for intermediate connector, material selection carbon tool steel.
Further, critical component of the apparatus body 3 for the device, material selection carbon steel.
Further, the connector 4 realizes that the positioning to digital display meter 5 clamps, while uses and be interference fitted with apparatus body 3, Convenient for maintaining, material selection carbon steel.
