Description

Technical Field

[0001] The utility model relates to the technical field of calipers, in particular to a self-made caliper for preventing end plates from shifting. Background Art

[0002] A caliper is a measuring tool used to measure length, inner and outer diameters, and depth. It has the function of measurement and inspection. The measuring jaws are divided into inner measuring jaws and outer measuring jaws. The inner measuring jaws are usually used to measure the inner diameter, and the outer measuring jaws are usually used to measure the length and outer diameter.

[0003] The Chinese patent application with the patent application number CN201020683367.5 discloses a vernier caliper, including a main scale and a vernier, wherein the main scale is provided with an outer measuring claw, an inner measuring claw and a depth gauge, and a slide groove is provided on one side of the inner measuring claw for measuring, and a measuring needle is installed on the slide groove. Due to the adoption of the above technical scheme, the utility model can slide the two measuring needles out of the inner measuring claw and insert the measuring needles into the hole for measurement. The utility model can measure holes with a small diameter that the inner measuring claw cannot insert into the hole. The method is simple and fast, easy to use, and has high measurement accuracy. However, when a part of some large objects needs to be measured, it is often inserted into the interior for measurement, but the existing measuring tools do not have such a large depth and cannot reach the required measurement position. Rough measurement leads to low accuracy and slow production efficiency. Utility Model Content

[0004] In order to overcome the defect that the depth component cannot be measured in the prior art, the utility model provides a self-made caliper which can prevent the end plate from shifting and can measure the depth component with high precision.

[0005] The utility model solves the technical problem by adopting the following technical scheme: a self-made caliper for preventing the end plate from shifting, comprising a guide scale and a vernier block, wherein the vernier block is sleeved outside the guide scale, the vernier block and the guide scale are relatively slidably connected, the left end of the vernier block is provided with a right clamping claw, the left end of the guide scale is provided with a left clamping claw, the right clamping claw corresponds to the left clamping claw; a right cross clamping groove which is concave downwards is provided on the right clamping claw, a right extension claw is installed on the right cross clamping groove, a left cross clamping groove which is concave downwards is provided on the left clamping claw, and a left extension claw is installed on the left cross clamping groove.

[0006] As a further improvement of the utility model, the right extending claw and the left extending claw are respectively embedded in the right cross slot and the left cross slot, which is convenient for disassembly and installation.

[0007] As a further improvement of the utility model, the right extending claw and the left extending claw are both cross-shaped plates, which can be engaged with the right cross-shaped slot and the left cross-shaped slot.

[0008] As a further improvement of the present invention, both ends of the right extending claw and the left extending claw are respectively located in the same plane as the side surfaces of the right clamping claw and the left clamping claw, thereby improving the detection accuracy.

[0009] As a further improvement of the utility model, fastening bolts are provided on the front sides of the right clamping jaw and the left clamping jaw to facilitate fixation and improve detection accuracy.

[0010] As a further improvement of the utility model, a fixing bolt is provided on the vernier block to facilitate fixing and improve detection accuracy.

[0011] Compared with the prior art, the utility model has the beneficial effects: in this solution, the right extension claw and the left extension claw are respectively embedded in the right cross slot and the left cross slot, and the right extension claw and the left extension claw are long enough to extend into the depth component, which is convenient for measuring the internal dimensions of the depth component, ensuring the accuracy of the measured object and improving production efficiency.
