Description

Technical Field

[0001] This utility model relates to the technical field of mechanical measuring devices for testing, and specifically to a mechanical measuring device for testing. Background Technology

[0002] In the field of scientific research, tensile testers are widely used in experiments in disciplines such as materials science, mechanical engineering, and civil engineering. Researchers use tensile testers to conduct tensile tests on materials or structures in order to study their mechanical properties, failure mechanisms, and optimization design schemes. The high precision and stability of tensile testers provide reliable data support for scientific research experiments and promote the development of related disciplines.

[0003] According to Chinese Patent No. CN220649842U, a mechanical measuring device for testing is provided, relating to the field of measuring device technology. The device includes a measuring device body with a measuring adapter component at its top. The measuring device body is connected to a hook via the measuring adapter component. The measuring adapter component includes a connecting sleeve plate disposed on the top of the measuring device body. This invention, by setting corresponding working adapter components and measuring adapter components, allows for actual replacement and adaptation of the hook via the measuring adapter component. Simultaneously, the working adapter component can be used to adapt the device for operator use. This minimizes the technical problem of inaccurate measurement or damage to the tensile tester if the tensile force of the object being measured exceeds its range due to the limited range of the tensile tester. Furthermore, it avoids the subsequent problem of being unable to continue measurement and affecting overall use if the tensile tester is damaged and detached during actual use.

[0004] In the above solution, it was found that the hook of the mechanical measuring device does not have an anti-detachment function. If the hook does not have an anti-detachment function, when the tensile force exceeds the hook's load-bearing capacity or when it is subjected to an accidental impact, the heavy object may fall off the hook, which may not only damage the measuring device, but also cause serious injury to the operator. The falling of the heavy object or the loosening of the hook may lead to instability in the measurement process and affect the accuracy of the measurement results. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mechanical measuring device for testing, which solves the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A mechanical measuring device for testing includes: a main body, a force-measuring spring fixedly installed on the top surface inside the main body, a measuring plate fixedly installed on the bottom of the force-measuring spring, the measuring plate being movably sleeved inside the main body, an insertion hole opened on the bottom surface inside the main body, a connecting rod fixedly installed on the bottom of the measuring plate, and the insertion hole being movably sleeved with the connecting rod; and an anti-detachment component, which is disposed at the bottom of the main body to prevent heavy objects from falling off.

[0008] By adopting the above technical solution, the main body provides a platform for the installation and support of other components. The elastic deformation characteristics of the force-measuring spring can convert the weight of the object being measured into the compression of the spring. The weight of the object can then be indirectly measured by measuring this compression. The measuring plate directly bears the weight of the object being measured and transmits it to the force-measuring spring. The insertion hole and connecting rod ensure that the measuring plate can move smoothly inside the main body when under force. The anti-detachment component prevents the object being measured from falling out of the device due to accidental reasons during the measurement process, thereby protecting the safety of the operator and the surrounding environment.

[0009] Preferably, the anti-detachment component includes: a rectangular block, the rectangular block being fixedly installed at the bottom of the connecting rod, an adjustment hole being provided on one side of the rectangular block, a hook being fixedly installed at the bottom of the rectangular block, and an anti-detachment groove being provided at the top of the hook.

[0010] By adopting the above technical solution and setting up a rectangular block, a stable installation platform is provided for subsequent components such as adjustment holes and hooks. The adjustment holes are used to place and adjust the lever, the hooks are used to hook the object being measured or related connecting parts, and the anti-disengagement groove is used to place the pin and prevent the pin from shifting position.

[0011] Preferably, the anti-detachment component further includes: a mounting groove, the mounting groove being formed at the bottom of the rectangular block, the adjustment hole communicating with the mounting groove, a strong spring being fixedly installed on the inner top surface of the mounting groove, a pin being fixedly installed at the bottom of the strong spring, the pin being movably sleeved inside the mounting groove, a lever being fixedly installed on the outer circular wall of the pin, the lever being movably sleeved inside the adjustment hole, and the pin being movably sleeved with the anti-detachment groove.

[0012] By adopting the above technical solution and setting the mounting groove, installation space is provided for components such as the strong spring and the pin, and it is also ensured that they can be stably fixed on the rectangular block. The elastic characteristics of the strong spring allow the pin to generate the necessary displacement when subjected to external force, and at the same time, it can quickly return to its original position. Its strong elasticity also ensures that the pin can be tightly locked into the anti-disengagement groove to prevent the object from falling off. The tight fit between the pin and the anti-disengagement groove can ensure that the measured object or connecting part will not fall off during the measurement process. The lever allows users or maintenance personnel to move the position of the pin through simple operation.

[0013] Preferably, two limiting rods are fixedly installed on the inner bottom surface of the main body, and two limiting holes are opened on the top surface of the measuring plate, with the limiting holes and limiting rods being movably sleeved together.

[0014] By adopting the above technical solution and setting a limiting rod, the measuring plate is guided and limited during its up and down movement. The limiting rod can ensure that the measuring plate always moves along the predetermined trajectory when under force, avoiding measurement errors caused by offset or shaking. The limiting hole allows the measuring plate to move smoothly under the guidance of the limiting rod.

[0015] Preferably, a connecting block is fixedly installed on one side of the measuring plate, and a pointer is fixedly installed on one side of the connecting block.

[0016] By adopting the above technical solution and setting a connecting block, it is ensured that the pointer can be stably fixed on the measuring plate. As the measuring plate moves up and down under force, the pointer will move accordingly, thereby indicating the weight or mechanical parameters of the object being measured.

[0017] Preferably, a protective plate is fixedly installed on one side of the main body, an indicator hole is opened on one side of the protective plate, the connecting block is movably sleeved inside the indicator hole, and a scale is fixedly installed on one side of the protective plate.

[0018] By adopting the above technical solution and setting up a protective plate, the main function is to protect the interior of the main body and prevent external objects or impurities from damaging the interior of the main body, thus ensuring the accuracy and stability of the measurement process. The indicator hole is opened on one side of the protective plate so that the pointer can pass through the protective plate without affecting the normal movement of the measuring plate. The scale provides a clear measurement standard and reference, and the pointer indicates the current measurement value in real time as the measuring plate moves.

[0019] In summary, the present invention has the following main advantages:

[0020] The main body provides a platform for the installation and support of other components. The elastic deformation characteristics of the force-measuring spring can convert the weight of the measured object into the spring's compression. The measuring plate is used to transfer this to the force-measuring spring. The insertion hole and connecting rod ensure that the measuring plate can move smoothly inside the main body when under force. The anti-detachment component prevents the measured object from falling out of the device due to accidental reasons during the measurement process. A rectangular block is set up to provide a stable mounting platform for subsequent components such as adjustment holes and hooks. The adjustment hole is used to place and adjust the lever, the hook is used to hook the measured object or related connecting parts, and the anti-detachment groove is used to place the pin to prevent the pin from shifting position. The mounting groove is set up to provide installation space for components such as the strong spring and the pin. The elastic characteristics of the strong spring allow the pin to generate the necessary displacement when subjected to external force, while quickly returning to its original position. Its strong elasticity also ensures that the pin can be tightly locked into the anti-detachment groove. The tight fit between the pin and the anti-detachment groove ensures that the measured object will not fall off. The lever allows users or maintenance personnel to move the position of the pin through simple operation.

[0021] A limit rod is provided to guide and limit the movement of the measuring plate during its up-and-down motion. The limit rod ensures that the measuring plate always moves along a predetermined trajectory when under force. The limit hole allows the measuring plate to move smoothly under the guidance of the limit rod. A connecting block is provided to ensure that the pointer can be stably fixed on the measuring plate. The pointer moves accordingly as the measuring plate moves up and down under force, thus indicating the weight or mechanical parameters of the measured object. A protective plate is provided to protect the internal structure of the main body. The indicator hole is opened on one side of the protective plate so that the pointer can pass through the protective plate without affecting the normal movement of the measuring plate. The scale provides a clear measurement standard and reference, and the pointer indicates the current measurement value in real time as the measuring plate moves. Attached Figure Description
