Description

Technical Field

[0001] The utility model belongs to the technical field of vernier calipers, and in particular relates to an improved vernier caliper. Background Art

[0002] Vernier caliper is a measuring tool for measuring length, inner and outer diameter, and depth. The vernier caliper consists of a main scale and a sliding vernier attached to the main scale. From the back, the vernier is a whole. The depth gauge is connected to the vernier scale and can measure the depth of the groove and the barrel. Since the depth gauge is a slender rod, and the depth measuring rod will extend when measuring the diameter or inner diameter of the part, if the vernier caliper falls accidentally, the depth measuring rod will be easily deformed after landing, which may affect the depth measurement accuracy of the vernier caliper, and the depth measurement function of the vernier caliper will not work properly. Utility Model Content

[0013] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 and attached Figure 2 As shown, an improved vernier caliper comprises a main scale 1, on the outer wall of which a detachable depth measuring assembly 2 is slidably mounted; outer measuring jaws 3 are fixedly connected to the lower left side of the main scale 1 and the lower left side of the detachable depth measuring assembly 2, respectively, and the detachable depth measuring assembly 2 is located on the right side of the outer measuring jaw 3 connected to the main scale 1; inner measuring jaws 4 are fixedly connected to the upper left front side of the main scale 1 and the upper left rear side of the detachable depth measuring assembly 2, respectively; a slide groove 5 is provided at the inner middle rear side of the main scale 1; and the detachable depth measuring assembly 2 is also slidably arranged inside the slide groove 5.

[0014] In this embodiment, combined with the Figure 3 As shown, the detachable depth measuring assembly 2 includes a vernier scale 21, an internal threaded sleeve 22 is laterally integrated and connected to the middle part of the inner rear of the vernier scale 21, and a threaded rod 23 is threadedly connected to the right side of the inner part of the internal threaded sleeve 22, wherein the right end of the threaded rod 23 is integrally connected to the depth measuring rod 24; the left end of the depth measuring rod 24 is tightly pressed against the right end of the internal threaded sleeve 22; a fastening screw 25 is threadedly connected to the opening in the middle part of the upper part of the vernier scale 21.

[0015] In this embodiment, specifically, the vernier scale 21 is slidably mounted on the outer wall of the main scale 1 , and the vernier scale 21 is fastened to the main scale 1 by a fastening screw 25 , wherein the vernier scale 21 is located on the right side of the outer measuring claw 3 connected to the main scale 1 .

[0016] In this embodiment, specifically, the lower left side of the vernier scale 21 is fixedly connected with an outer measuring claw 3 .

[0017] In this embodiment, specifically, the internal threaded sleeve 22 is slidably disposed inside the slide groove 5 , and a depth measuring rod 24 is also slidably disposed inside the slide groove 5 .

[0018] In this embodiment, specifically, the inner measuring claw 4 is fixedly connected to the upper left rear side of the vernier scale 21 .

[0019] In this embodiment, specifically, when the outer jaws 3 fit together, the inner jaws 4 also fit together, and the "0" scale line of the vernier scale 21 coincides with the "0" scale line of the main scale 1, while the right end of the depth measuring rod 24 is flush with the right end of the main scale 1.

[0020] In this embodiment, specifically, the slide groove 5 is a groove with a longitudinal section in the shape of an arc.

[0021] In this embodiment, specifically, the depth measuring rod 24 is a rod with a circular longitudinal section.

[0022] In this embodiment, specifically, the diameter of the depth measuring rod 24 is equal to the outer diameter of the internal threaded sleeve 22 .

[0023] In this embodiment, when the depth measurement function is not used, the operator can push the vernier ruler 21 to the right, so that the vernier ruler 21 pushes the depth measuring rod 24 to the right through the internal threaded sleeve 22 and the threaded rod 23, and the depth measuring rod 24 will extend from the inside of the slide groove 5. Then the operator can rotate the depth measuring rod 24, and the depth measuring rod 24 will drive the threaded rod 23 to rotate until the threaded rod 23 is screwed out of the inside of the internal threaded sleeve 22. Then the operator can continue to pull the depth measuring rod 24 to completely move the depth measuring rod 24 out of the inside of the slide groove 5, and then the operator can adjust the depth measuring rod 24. The depth measuring rod 24 can be saved, so when the vernier caliper falls to the ground, the depth measuring rod 24 will not be damaged. Since the rest of the structure of the vernier caliper is relatively thick, falling to the ground will not cause damage to the vernier caliper. When using the depth measurement function, the operator can insert the depth measuring rod 24 into the slide groove 5, and screw the threaded rod 23 on the depth measuring rod 24 into the interior of the internal threaded sleeve 22. Since the depth measuring rod 24 can be disassembled, the depth measuring rod 24 can be replaced even if it falls and deforms, thereby avoiding the problem of the vernier caliper losing the depth measurement function, and achieving the effect of facilitating the disassembly of the depth measuring rod 24.

[0024] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
