[0002] In the field of precision measurement, as a basic and widely used tool, the accuracy and stability of measuring calipers are crucial for ensuring product quality and process precision. Traditional measuring calipers, such as vernier calipers, dial calipers, etc., although they can provide basic linear dimension measurement functions, still face some challenges in actual applications.

[0003] When the object to be measured is not in a completely horizontal position, traditional measuring calipers often have difficulty ensuring the accuracy of the measurement reference. Due to the action of gravity or improper operation, it is easy to cause an inclination between the clamping part of the caliper and the object to be measured, resulting in deviation in measurement data. This deviation is particularly critical in fields such as precision machining, mechanical manufacturing, and electronic component assembly, and can directly affect the overall performance and reliability of the product. Content of the Utility Model

[0004] (I) Purpose of the Utility Model

[0005] In view of this, the purpose of the present utility model is to propose a measuring caliper with a limiting mechanism, which solves the problems raised in the above background.

Connecting plates are fixedly installed on both sides of the main body of the measuring caliper, and a first annular groove and a second annular groove are formed on the outer surface of the bottom end of the connecting plate. A vertical adjustment groove is opened between the first annular groove and the second annular groove. A shaft rod is movably installed on the inner wall of the first annular groove. One side of the shaft rod is connected with a circular plate, and the other side of the shaft rod is connected with an adjusting rod. A sliding groove is formed on the outer surface of the adjusting rod. A limiting plate is movably installed on the inner wall of the sliding groove, and a horizontal bubble level is arranged on the outer surface of one side of the limiting plate.

[0023] The following description is merely exemplary in nature and is not intended to limit the present disclosure, its application, and uses. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. Each drawing only schematically shows the concept and principle of the embodiments of the present disclosure, and does not necessarily show the specific dimensions and their ratios of the various embodiments of the present disclosure. Specific parts in a particular drawing may be exaggerated to illustrate relevant details or structures of the embodiments of the present disclosure.

[0024] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0025] A measuring caliper with a limiting mechanism, comprising a measuring caliper main body 1. Connecting plates 2 are fixedly installed on both sides of the measuring caliper main body 1. The bottom outer surface of the connecting plate 2 is provided with a first annular groove 3 and a second annular groove 5. A vertical adjustment groove 4 is opened between the first annular groove 3 and the second annular groove 5. A shaft rod 412 is movably installed on the inner wall of the first annular groove 3. One side of the shaft rod 412 is connected with a round plate 411, and the other side of the shaft rod 412 is connected with an adjusting rod 6. A sliding groove 8 is opened on the outer surface of the adjusting rod 6. A limiting plate 9 is movably installed on the inner wall of the sliding groove 8. A horizontal bubble level 511 is arranged on the outer surface of one side of the limiting plate 9.

[0026] Furthermore, a first magnetic attraction plate 7 is fixedly installed on the outer surface of one side of the bottom ends of the two groups of connecting plates 2, and the first magnetic attraction plate 7 is horizontally installed at a right angle. The first magnetic attraction plates 7 installed at the bottom ends of the two groups of connecting plates 2 are horizontally installed at a right angle, ensuring that the adjusting rod 6 can be stably adsorbed when rotated to the horizontal position at a right angle, preventing deviation from the horizontal state due to external force or vibration. This not only improves the measurement accuracy but also simplifies the operation process, making the adjustment more convenient and fast.

[0027] Furthermore, screw grooves 211 are opened on the outer surfaces of both sides of the limiting plate 9. A screw rod 212 is movably installed on the inner wall of the screw groove 211. One end of the screw rod 212 is connected with a clamping plate 911. An operating rod 912 is fixedly installed on the outer surface of the clamping plate 911. The cooperation of the screw grooves 211 opened on both sides of the limiting plate 9 and the screw rod 212 allows the user to tighten or loosen the limiting plate 9 by rotating the operating rod 912 to achieve precise adjustment of its position. This design improves the stability and adjustability of the limiting plate 9, ensuring that it can stably resist the measured object during the measurement process and avoiding measurement errors.

[0028] Furthermore, the outer surface of the rotating operating rod 912 is serrated. The serrated outer surface design increases the friction between the operating rod 912 and the user's hand, enabling a more stable grip during rotation operation and reducing operation errors or accuracy degradation caused by hand slippage.

[0029] Further, an installation groove 913 is formed on the outer surface of one side of the main body 1 of the measuring caliper. The installation groove 913 provides a dedicated storage and fixing position for the limiting plate 9. This not only maintains the neatness of the measuring caliper in the non-use state, but also takes into account portability, making the whole measuring caliper more compact and convenient to carry.

[0030] Further, a plurality of groups of second magnetic attraction plates 914 are fixedly installed on the inner wall of the installation groove 913. The fixed installation of the plurality of groups of second magnetic attraction plates 914 enables the limiting plate 9 or other magnetic accessories to be firmly adsorbed in the installation groove 913. This magnetic adsorption method not only simplifies the installation and disassembly process, but also improves the reliability and stability of the component fixation.

[0031] Further, the outer surface of the operating rod 912 is wrapped with rubber. The rubber-wrapped operating rod 912 not only provides better holding comfort, but also enhances the anti-slip performance. The rubber material has good elasticity and wear resistance, and can maintain a good hand feeling after long-term use.

[0032] Working principle: When using the main body 1 of the measuring caliper, first, the main body 1 of the measuring caliper clamps the object to be measured. Then, by sliding the shaft rod 412, the shaft rod 412 is placed at a right angle in the second annular groove 5. At this time, through the action of the first magnetic attraction plate 7, the adjusting rod 6 can be adsorbed, and then the adjusting rod 6 can be kept horizontal at a right angle to ensure the accuracy of the measurement reference. After the adjusting rod 6 is in a horizontal state, slide the limiting plate 9 in the sliding groove 8 to make it gradually approach and press against the outer surface of the object to be measured. By observing the level bubble 511, the position of the limiting plate 9 can be accurately adjusted until the bubble indicates a complete horizontal state, ensuring that the included angle between the object to be measured and the main body 1 of the measuring caliper is a right angle, thereby improving the measurement accuracy. Then, use the operating rod 912 to rotate the screw rod 212 to tightly connect it with the screw grooves 211 on both sides of the limiting plate 9. Then, the limiting plate 9 is firmly fixed on the adjusting rod 6 through the clamping plate 911 to prevent it from moving during the measurement process. After the limiting plate 9 is stably fixed, accurate measurement operations can be carried out. At this time, the reading of the main body 1 of the measuring caliper will accurately reflect the size of the object to be measured. After the measurement is completed, through reverse operation, the shaft rod 412 is moved back from the second annular groove 5 to the first annular groove 3, the adjusting rod 6 is folded back to its initial position, and the limiting plate 9 is installed in the installation groove 913 on the clamping plate 911 and kept stable by the magnetic force of the second magnetic attraction plate 914, which is convenient for overall storage and carrying.

Therefore, in any aspect, the embodiments should be regarded as exemplary and non-restrictive.
