Description

Technical Field

[0001] This utility model relates to the field of shoe processing technology, specifically to a tensile testing machine with high-precision measurement function. Background Technology

[0002] Currently, most shoes use strong adhesive to bond the sole and upper together. After the shoes are manufactured, it is often necessary to test the adhesion between the sole and upper. This requires the use of a tensile testing machine. Existing tensile testing machines include a base, a guide rod vertically mounted on the base, and a sliding block slidably mounted on the guide rod. The control end is also the tensile force display end. The sole and upper of the shoe are clamped and fixed by a clamping mechanism. If the guide rod pulls them apart, the tensile force applied to the shoe by the tensile testing machine is displayed on the display end, thus completing the testing work.

[0003] Existing tensile testing machines on the market generally rely on clamping methods to stabilize and limit the sole and upper of the shoe. By increasing the distance between the clamping components of the sole and upper, tensile force is applied to the shoe to achieve testing. However, in actual use, due to the different clamping and installation methods of the two clamping components, the applied force cannot be strictly controlled to be in the same straight line, and may generate spiral stress in different directions. If it cannot be flexibly adjusted, it may affect the actual testing accuracy. Therefore, we propose a tensile testing machine with high-precision measurement function. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tensile testing machine with high-precision measurement capabilities. This solves the problem that, in actual use, due to differences in the clamping and installation methods of the two clamping components, the applied force cannot be strictly controlled to be in the same straight line, which may generate spiral stresses in different directions. If these stresses cannot be flexibly adjusted, they may affect the actual testing accuracy.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A tensile testing machine with high-precision measurement function includes a first fixed block, a first fixed plate fixedly mounted on the top surface of the first fixed block, a snap-fit ​​hole on one side of the first fixed plate, a connecting rod disposed inside the snap-fit ​​hole, the connecting rod consisting of a cylindrical part and a disc part, a snap-fit ​​ring fixedly mounted on the outer wall of the cylindrical part of the connecting rod, the connecting rod being snapped into the snap-fit ​​hole through the disc part of the connecting rod and the snap-fit ​​ring, a rotating groove on one side of the cylindrical part of the connecting rod, snap-fit ​​blocks fixedly mounted on both sides of the rotating groove, an mounting sleeve on one side of the connecting rod, a connecting block fixedly mounted on one side of the mounting sleeve, and snap-fit ​​grooves on both sides of the connecting block, the mounting sleeve being snapped into the rotating groove through the snap-fit ​​block, the connecting block and the snap-fit ​​grooves, and a force gauge being snapped into the inside of the mounting sleeve.

[0006] Preferably, a second fixing block is fixedly installed on one side of the first fixing block. The second fixing block has a convex block structure. Sliding grooves are provided on both sides of the second fixing block. A sliding plate is provided on the top surface of the second fixing block. Two connecting plates are fixedly installed on the bottom surface of the sliding plate. An arc block is fixedly installed on one side of the connecting plate. The sliding plate is engaged with the second fixing block through the connecting plate, the arc block and the sliding groove.

[0007] Preferably, two limiting plates are fixedly installed on the top surface of the sliding plate, and a limiting groove is formed on one side of the limiting plate.

[0008] Preferably, a threaded tube is engaged inside the limiting groove, and an adjusting rod is threadedly connected inside the threaded tube. The adjusting rod consists of a threaded rod portion and a disc portion. A clamping plate is provided on one side of the limiting plate, and both clamping plates are located on the top surface of the second fixing block. A connecting sleeve is fixedly installed on one side of the clamping plate, and the connecting sleeve and the disc portion of the adjusting rod are engaged together.

[0009] Preferably, a contact pad is fixedly installed on one side of the clamping plate, and the contact pad is made of rubber.

[0010] Preferably, a second fixing plate is fixedly installed on one side of the sliding plate, and a connection hole is provided on the top surface of the second fixing plate.

[0011] In summary, the present invention has the following main advantages: By incorporating snap-fit ​​holes, a connecting rod, and a snap-fit ​​ring, the snap-fit ​​mechanism allows the force gauge to rotate at any time during measurement, adapting to different installation positions with the shoe body and varying fixed positions of the sole and upper. This ensures high-precision tensile force measurement. The design of the rotating groove, snap-fit ​​block, connecting block, and snap-fit ​​slot further increases the adjustable angle of the force gauge, enhancing the device's adaptability to tensile force direction and ensuring even higher precision in tensile force measurement. By setting limit plates, the two sides of the shoe can be limited to prevent deviation during the pulling test. On the other hand, the movement trajectory of the clamping element of the sole can be restricted by the limit groove, so that it can be adjusted according to the specified trajectory. The design of the adjustment rod can adjust the distance between the two clamping plates by turning the adjustment rod, thereby clamping the sole of the shoe. As the clamping element of the sole, the snap-fit ​​design of the adjustment rod and the connecting sleeve can prevent the clamping plate from blocking the device during the turning of the adjustment rod, thus preventing the device from becoming unusable.

A connecting rod 4 is arranged inside the snap-fit ​​hole 3. The connecting rod 4 is composed of a cylindrical part and a disc part. A snap-fit ​​ring 5 is fixedly installed on the outer wall of the cylindrical part of the connecting rod 4. The connecting rod 4 is snapped into the inside of the snap-fit ​​hole 3 through the disc part of the connecting rod 4 and the snap-fit ​​ring 5. A rotating groove 6 is opened on one side of the cylindrical part of the connecting rod 4. Snap-fit ​​blocks 7 are fixedly installed on both sides of the rotating groove 6. An installation sleeve 8 is provided on one side of the connecting rod 4. A connecting block 9 is fixedly installed on one side of the installation sleeve 8. Snap-fit ​​blocks 9 are opened on both sides of the connecting block 9. The mounting sleeve 8 is snapped into the rotating groove 6 via the snap-fit ​​block 7, connecting block 9, and snap-fit ​​groove 10. The force gauge 11 is snapped into the inside of the mounting sleeve 8. Through the design of the snap-fit ​​hole 3, connecting rod 4, and snap-fit ​​ring 5, the snap-fit ​​method allows the force gauge 11 to rotate at any time during the measurement process, depending on the different installation positions of the force gauge 11 with the shoe body and the positional differences of the fixed positions of the sole and the shoe body. This ensures high-precision measurement of the tensile force by the force gauge 11. The design of the rotating groove 6, snap-fit ​​block 7, connecting block 9, and snap-fit ​​groove 10 further increases the adjustable angle of the force gauge 11, further increasing the adaptability of the device to the direction of tensile force and ensuring that the device can measure the tensile force with higher precision. A second fixing block 12 is fixedly installed on one side of the first fixing block 1. The second fixing block 12 has a convex block structure. Sliding grooves 16 are provided on both sides of the second fixing block 12. A sliding plate 13 is provided on the top surface of the second fixing block 12. Through the design of the sliding plate 13, the position of the sliding plate 13 can be adjusted at any time by the snap-fit ​​design. With the clamping element of the shoe sole, the tensile force can be applied, thereby measuring the strength of the shoe. Two connecting plates 14 are fixedly installed on the bottom surface of the sliding plate 13. An arc block 15 is fixedly installed on one side of the connecting plate 14. The sliding plate 13 is snapped together with the second fixing block 12 through the connecting plate 14, the arc block 15 and the sliding groove 16. Two limiting plates 17 are fixedly installed on the top surface of the sliding plate 13. A limiting groove 18 is opened on one side of the limiting plate 17. Through the design of the limiting plate 17, on the one hand, the two sides of the shoe can be limited to avoid the deviation of the two sides during the pulling test. On the other hand, the movement trajectory of the clamping element of the sole can be limited by the limiting groove 18, so that it can be adjusted according to the specified trajectory. A threaded tube 19 is snapped into the inside of the limiting groove 18. An adjusting rod 20 is threaded into the inside of the threaded tube 19. The adjusting rod 20 consists of a threaded rod part and a disc part. A clamping plate 21 is provided on one side of the limiting plate 17.

The connecting sleeve 22 and the disc part of the adjusting rod 20 are snapped together. Through the design of the adjusting rod 20, the distance between the two clamping plates 21 can be adjusted by turning the adjusting rod 20, thereby clamping the sole of the shoe. As a clamping element for the sole, the snap-fit ​​design of the adjusting rod 20 and the connecting sleeve 22 can prevent the clamping plate 21 from blocking during the turning of the adjusting rod 20, thus preventing the device from becoming unusable. A contact pad 23 is fixedly installed on one side of the clamping plate 21. The contact pad 23 is made of rubber. The design of the contact pad 23 can increase the friction between the clamping plate 21 and the contact part of the shoe sole, and avoid slipping during the pulling process, which could cause it to fall off and affect the final measurement results. A second fixing plate 24 is fixedly installed on one side of the sliding plate 13. A connecting hole 25 is provided on the top surface of the second fixing plate 24. The design of the connecting hole 25 can provide a force point, making it convenient to drive the sliding plate 13 manually or automatically, providing the required pulling force for the device, and ensuring that the device can be used normally.
