Description

Technical Field

[0001] The present application relates to the technical field of measuring tools, and in particular to a distance measuring tool. Background Art

[0002] Measuring tools are instruments used for measurement and inspection, and length measuring tools are one of the main categories, such as calipers, depth gauges, height gauges, micrometers, dial indicators, micrometers, gauge blocks, step gauges, angle rulers, inclinometers, etc. Calipers are one of the most important types of length measuring tools.

[0003] In the actual use of measuring calipers, they are mostly fixed devices. When the measured distance exceeds the measuring tool itself, it is necessary to mark it and move the measuring tool again to perform the measurement operation, which will cause certain errors and make the measurement data inaccurate, reduce work efficiency, and have poor practicality. Therefore, a distance measuring tool is needed to improve the above problems. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the present application provides a distance measuring tool which realizes the extension operation of the first distance measuring ruler through the cooperation of an adjustment mechanism, improves work efficiency, and has high practicality.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a distance measuring tool, comprising a first distance measuring ruler, two mounting plates are symmetrically fixedly installed on the first distance measuring ruler, a plurality of slots are provided on each mounting plate, a working cavity is provided on the first distance measuring ruler, a second distance measuring ruler is slidably installed in the working cavity, scale lines are provided on the first distance measuring ruler and the second distance measuring ruler, two limit blocks are symmetrically fixedly installed at both ends of the second distance measuring ruler, two limit slots are symmetrically provided at both ends of the working cavity, and the two limit blocks and the two limit slots are slidably connected;

[0008] The second range-measuring ruler is provided with an adjustment mechanism, which includes two fixed plates. A slider is fixedly installed on the second range-measuring ruler, and telescopic columns are fixedly installed at both ends of the slider. One end of the two telescopic columns away from the slider is fixedly connected to the two fixed plates respectively. Springs are mounted on the two telescopic columns, and the two ends of the two springs are fixedly connected to the slider and the corresponding fixed plates respectively. A clamping block is fixedly installed on each fixed plate, and one of the clamping blocks is clamped in one of the clamping slots on the same side.

[0009] Preferably, a mounting plate is fixedly mounted on the first ranging ruler.

[0010] Furthermore, auxiliary blocks are fixedly mounted on the two fixing plates.

[0011] Furthermore, the sliding block is provided with anti-slip grooves.

[0012] Based on the above solution, a rubber pad is provided at the bottom end of the first distance measuring ruler.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the present application provides a distance measuring tool, which has the following beneficial effects:

[0015] The distance measuring tool performs measurement operation through the first distance measuring ruler. When the size of the first distance measuring ruler is not enough, the two fixing plates are squeezed to compress the two springs, so that the two clamping blocks are separated from the two clamping grooves, and the slide block is pushed, thereby driving the second distance measuring ruler to slide in the first distance measuring ruler. The position of the slide block is adjusted according to actual needs, and the two fixing plates are loosened. The two springs drive the two clamping blocks to be clamped in the corresponding two clamping grooves through their own elastic force, so as to limit the slide block, thereby realizing the extension operation of the first distance measuring ruler, improving work efficiency, and having high practicality.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] Example

[0023] See also Figure 1-3A distance measuring tool comprises a first distance measuring ruler 1, on which two mounting plates 2 are symmetrically fixedly installed, each mounting plate 2 is provided with a plurality of slots 3, a working cavity is provided on the first distance measuring ruler 1, in which a second distance measuring ruler 4 is slidably installed, scale lines are provided on the first distance measuring ruler 1 and the second distance measuring ruler 4, two limit blocks 5 are symmetrically fixedly installed at both ends of the second distance measuring ruler 4, two limit slots 6 are symmetrically provided at both ends of the working cavity, and the two limit blocks 5 and the two limit slots 6 are slidably connected.

[0024] See also Figure 1-4 The second measuring scale 4 is provided with an adjustment mechanism, which includes two fixed plates 8. A slider 7 is fixedly installed on the second measuring scale 4. Telescopic columns 9 are fixedly installed at both ends of the slider 7. One end of the two telescopic columns 9 away from the slider 7 is fixedly connected to the two fixed plates 8 respectively. Springs 10 are mounted on the two telescopic columns 9. The two ends of the two springs 10 are fixedly connected to the slider 7 and the corresponding fixed plates 8 respectively. The first measuring scale 1 is used for measuring. When the size of the first measuring scale 1 is not enough, the two springs 10 are compressed by squeezing the two fixed plates 8. During the contraction operation, a card block 11 is fixedly installed on each fixed plate 8, one of the card blocks 11 is carded with one of the card slots 3 on the same side, so that the two card blocks 11 are disengaged from the two card slots 3, and the slider 7 is pushed, thereby driving the second distance measuring scale 4 to slide in the first distance measuring scale 1. The position of the slider 7 is adjusted according to actual needs, and the two fixed plates 8 are loosened. Through the elastic force of the two springs 10 themselves, the two card blocks 11 are driven to be carded with the corresponding two card slots 3, so that the slider 7 is limited, and the extension operation of the first distance measuring scale 1 is realized.

[0025] See also Figure 1 A mounting plate 2 is fixedly mounted on the first distance measuring ruler 1, and the mounting plate 2 is installed to facilitate the carrying and hanging operation of the first distance measuring ruler 1.

[0026] See also Figure 1-4 Auxiliary blocks 13 are fixedly mounted on the two fixed plates 8, and the cooperation of the two auxiliary blocks 13 facilitates the movement of the two fixed plates 8.

[0027] See also Figure 1-4 It should also be noted that the slider 7 is provided with anti-skid patterns 14, and the provision of the anti-skid patterns 14 increases the friction force to prevent the hand from slipping.

[0028] See also Figure 1 and Figure 2 A rubber pad 15 is provided at the bottom end of the first measuring scale 1. The provision of the rubber pad 15 increases the friction force and prevents the first measuring scale 1 from being displaced.

[0029] In summary, when the distance measuring tool is in use, the first distance measuring ruler 1 is used for measuring, and the first distance measuring ruler 1 is prevented from displacement by the cooperation of the rubber pad 15. When the size of the first distance measuring ruler 1 is not enough, the two auxiliary blocks 13 are used to squeeze the two fixing plates 8, so that the two springs 10 are compressed, so that the two clamping blocks 11 are disengaged from two of the clamping slots 3, thereby releasing the limit operation of the slider 7, pushing the slider 7, thereby driving the second distance measuring ruler 4 to slide in the first distance measuring ruler 1, adjusting the position of the slider 7 according to actual needs, loosening the two fixing plates 8, and driving the two clamping blocks 11 to be clamped with the corresponding two clamping slots 3 through the elastic force of the two springs 10 themselves, thereby limiting the slider 7, and further realizing the extension operation of the first distance measuring ruler 1.
