Abstract
The utility model relates to a direct reading vernier caliper for measuring stadia and end distance of an angle steel hole. The direct reading vernier caliper comprises a vernier caliper body, a cone front measuring claw and a cone back measuring claw, wherein the cone front measuring claw and the cone back measuring claw are fixedly arranged at the lower end of the vernier caliper body; and a central line of the cone front measuring claw is coincided with zero scale of the caliper, and the back measuring claw moves on the vernier caliper body. When the direct reading vernier caliper is used for measuring the stadia and the end distance of the angle steel hole, the cone front measuring claw of the vernier caliper is inserted into a hole to be measured; angle steel backs or angle steel ends of the back measuring claw are close to each other; reading value is the stadia or the end distance of the angle steel hole; a step of calculating the value after two-time measurement is eliminated; and the efficiency and accuracy of the measuring work are greatly improved. The direct reading vernier caliper is simple in operation and convenient to use.
Description
Technical field
The utility model relates to the accurate distance in a kind of angle steel hole, end distance direct-reading vernier caliper.
Background technology
In iron tower of power transmission line manufacturing process; Use the accurate distance and the end distance in vernier caliper measurement angle steel hole; The distance of the center, angle steel hole and the angle steel back of the body is the accurate distance in angle steel hole; The center, hole of the end holes on the angle steel and the distance of angle steel termination are angle steel nose end distance, and standard apart from measuring process is: the first step, earlier with the hole wall in hole on the vernier caliper measurement angle steel and the distance between the angle steel back of the body (being the ribs that two faces of angle steel intersect); In second step,, calculate the radius that portals with the diameter in vernier caliper measurement hole; In the 3rd step, the numerical value that the first step is recorded and second goes on foot the radius addition in the hole that calculates, the accurate distance that must portal; If survey the end distance of end holes, measuring process is identical with the measured hole distance, and just the first step changes the hole wall of measurement angle steel end holes and the distance between the angle steel termination into; It is accurate apart from, end distance that such twice measurement and twice calculating just can draw the angle steel hole, both bothered, efficient is low and easy error.
The utility model content
The utility model technical matters to be solved provides a kind of efficient height, measures the accurate distance in angle steel hole, end distance direct-reading vernier caliper accurately.
The utility model adopts following technical scheme:
The utility model comprises the vernier caliper blade, is fixedly installed on the preceding measuring claw of cone and the back measuring claw of blade lower end, and the center line of measuring claw overlaps with slide calliper rule 0 scale mark before the described cone, and described back measuring claw moves on blade.
The utility model good effect is following: when the utility model is measured accurate distance in angle steel hole or end distance; In the hole that needs measuring claw insertion before the cone of vernier caliper to measure, the angle steel of back measuring claw and the angle steel back of the body or angle steel termination are close to, and the numerical value that reads is accurate distance in angle steel hole or end distance; Saved the step that twice measurement calculated again; The efficient and the accuracy rate of surveying work improve a lot, and the utility model is simple to operate, and is easy to use.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model working state structure synoptic diagram;
Accompanying drawing 3 is the utility model angle steel structural representation.
In the accompanying drawings: measuring claw, 3 back measuring claws, 4 angle steel before 1 blade, 2,5 angle steel holes.
Embodiment
Like accompanying drawing 1,2, shown in 3; The utility model comprises vernier caliper blade 1, is fixedly installed on the preceding measuring claw 2 of cone and the back measuring claw 3 of blade 1 lower end; The center line of measuring claw 2 overlaps with slide calliper rule 0 scale mark before the described cone, and described back measuring claw 3 moves on the blade lower end.When the utility model is measured accurate distance in angle steel hole or end distance; In the hole of angle steel 4 that need to measure measuring claw insertion before the cone of vernier caliper, back measuring claw 3 is close to angle steel 4 back ofs the body or angle steel 4 terminations of angle steel 4, and the numerical value that reads is angle steel hole 5 accurate distance or end distances; Saved the step that twice measurement calculated again; The efficient and the accuracy rate of surveying work improve a lot, and the utility model is simple to operate, and is easy to use.After before the utility model vernier caliper cone, marking scale on the measuring claw 2; Also can insert the aperture that the depth survey in angle steel holes 5 is portalled according to measuring claw before the cone 2; Thereby also can measure the aperture of portalling when the accurate distance in measurement angle steel hole or end distance, thereby can judge whether aperture size meets the requirements.
Claims (1)
1. an angle steel hole is accurate apart from, end distance direct-reading vernier caliper; It is characterized in that it comprises vernier caliper blade (1), is fixedly installed on measuring claw (2) and back measuring claw (3) before the cone of blade (1) lower end; The center line of measuring claw (2) overlaps with slide calliper rule 0 scale mark before the described cone, and described back measuring claw (3) moves on blade.
