[0036] The clamping mechanism includes two groups of abutment blocks 34, which are glued and fixed to one side of the fixed plate 33 close to the test sample 57, and the abutment block 34 abuts against the clamping plate 35. The bottom end of the clamping plate 35 is welded and fixed with a connecting spring 37, and the side of the connecting spring 37 away from the clamping plate 35 is fixed to the inner wall of the sleeve rod 38 by welding. The bottom end of the clamping plate 35 is inserted into the inside of the sleeve rod 38, and the bottom end of the sleeve rod 38 is inserted into the inside of the fixed sleeve block 43. The sleeve rod 38 and the fixed sleeve block 43 are both rectangular in design and the outer side of the sleeve rod 38 keeps in contact with the inner wall of the fixed sleeve block 43 to ensure that the sleeve rod 38 does not shake when sliding in the fixed sleeve block 43.

The first slider 44 and the second slider 50 are both trapezoidal in design to facilitate the movement of the top rod 41. The rear ends of the special-shaped connecting rod 45 and the connecting plate 49 are both fixed to the moving block 46 by welding. The special-shaped connecting rod 45 and the connecting plate 49 are both slidably connected to the inside of the movable groove 51. The movable groove 51 is opened inside the device base 1. The moving block 46 is threadedly connected to the left and right sides of the second rotating rod 47. The left and right sides of the second rotating rod 47 are provided with threads with opposite rotation directions.

The driving gear 52 is welded and fixed to the left side of the first rotating rod 26. The driven gear 48 and the driving gear 52 are both rotatably connected in the gear groove 56. The gear groove 56 is opened inside the device base 1.

[0037] A limit assembly is provided on the fixing frame 32, and the limit assembly includes a through slot 42, which is opened on the right fixing sleeve block 43, and a sliding rod 40 is slidably connected inside the through slot 42, and the sliding rod 40 is welded and fixed to the front and rear sides of the sleeve rod 38, and a rubber gasket 39 is glued and fixed on the sliding rod 40, and the rubber gasket 39 abuts against one side of the fixing frame 32;

[0038] During operation, through the structural design of the measuring mechanism, when the joint of the test sample 57 is damaged, the two sets of fixing plates 33 can be rotated to the front and rear sides of the test sample 57, so as to directly measure the maximum tensile length of the joint of the test sample 57 through the scale lines on the surface of the fixing plates 33, making the detection process more convenient and effectively improving the detection efficiency. First, the two sets of clamping blocks 22 clamp the upper and lower ends of the test sample 57, and then the hanger 21 is lifted upward until the joint of the test sample 57 is broken. At this time, the servo motor 2 is started to 8 drives the first rotating rod 26 to rotate, and the worm 27 fixed on the first rotating rod 26 drives a group of rotating gears 24 meshed therewith to rotate. Tooth grooves corresponding to the rotating gears 24 are provided on the front and rear sides of the transmission rod 25, so the group of rotating gears 24 meshed with the worm 27 can drive the transmission rod 25 to move. During the movement of the transmission rod 25, the other group of rotating gears 24 will be driven to rotate. The top of the rotating gear 24 is connected to the long rod 23, and the long rod 23 will rotate synchronously with the rotating gear 24. The connecting rods 31 are connected together by the supporting springs 53, so the connecting rods 31 can rotate together with the long rods 23, and the fixing frame 32 fixed on the top of the connecting rods 31 will rotate, thereby driving the fixing plate 33 to rotate until the fixing plate 33 rotates to the front and rear sides of the test sample 57. At this time, the test sample 57 can be measured by the scale lines engraved on the fixing plate 33, and the length data can be read directly from the fixing plate 33 to avoid the need to use other length measuring tools for operation, making the detection operation more convenient. Similarly, after the inspection of the test sample 57 is completed, the servo motor 28 is started again to rotate in the reverse direction, so that the fixed plate 33 can rotate in the reverse direction and move the fixed plate 33 away from the test sample 57. The bottom end of the connecting rod 31 is connected to the long rod 23 through the supporting spring 53. By pressing the fixing frame 32 downward or pulling the fixing frame 32 upward, the bottom end of the connecting rod 31 will move inside the long rod 23, so as to fine-tune the position height of the fixing plate 33 so that the fixing plate 33 can be aligned with the center of the joint of the test sample 57 for easy measurement.

[0039] Through the structural design of the clamping mechanism, when the inspector measures the inspection sample 57 through the fixing plate 33, the clamping plate 35 will clamp and fix the left and right sides of the inspection sample 57, so that the inspection sample 57 can be in a taut state, ensuring that the measurement result will not be affected by the bending of the inspection sample 57 during the measurement process. When the servo motor 28 drives the first rotating rod 26 to rotate, the driving gear 52 fixed on the left side of the first rotating rod 26 will also rotate synchronously, and drive the second rotating rod 47 connected to the driven gear 48 to rotate through the engagement with the driven gear 48. The left and right sides of the second rotating rod 47 are provided with threads with opposite rotation directions, so the two groups of moving blocks 46 threadedly connected to the second rotating rod 47 will move in opposite directions. During the movement of the two groups of moving blocks 46, the first slider 44 and the second slider 50 are driven to slide in the movable groove 51 respectively through the special-shaped connecting rod 45 and the connecting plate 49 connected thereto. The first slider 44 and the second slider 50 are When the top of the first slider 44 and the second slider 50 no longer abuts against the bottom end of the push rod 41, the sleeve rod 38 will slide inside the fixed sleeve block 43 under the action of gravity, and the clamping plate 35 will also move away from the test sample 57.

[0040] Through the structural design of the limit assembly, the maximum rotation angle of the two groups of fixed plates 33 is limited, so that the fixed plates 33 can remain parallel to the surface of the test sample 57 when they are rotated to the maximum angle, thereby ensuring the accuracy of the measurement results. When the fixed plates 33 are rotated to the maximum angle, the inner sides of the two groups of fixed frames 32 will abut against the rubber gaskets 39. At this time, the fixed plates 33 cannot continue to rotate. The rubber gaskets 39 are fixed on the sliding rod 40, and the sliding rod 40 is fixed on the sleeve rod 38. When the sleeve rod 38 slides in the fixed sleeve block 43, the sliding rod 40 will also slide in the through groove 42. The design of the rubber gasket 39 is to facilitate buffering between the sliding rod 40 and the fixed frame 32, thereby reducing the wear caused by the direct abutment between the fixed frame 32 and the sliding rod 40. Example

[0041] See also Figure 1 - Fig.11 As shown, compared with Example 1, as another embodiment of the present invention, the fixing plate 33 is rectangular in design, and the fixing plate 33 is made of highly transparent PP material;

[0042] During operation, the fixing plate 33 is rectangular in design and is made of highly transparent PP material, so that light can pass through the fixing plate 33 , so that the inspector can better measure the inspection sample 57 .

[0043] The cross section of the bottom end of the connecting rod 31 is designed to be T-shaped, and the bottom end of the connecting rod 31 is inserted into the interior of the long rod 23;

[0044] During operation, the bottom end of the connecting rod 31 is T-shaped. When the fixing frame 32 is pulled upward to the maximum height, the bottom end of the connecting rod 31 will abut against the inside of the long rod 23 to limit the upward movement range of the fixing frame 32, thereby preventing the support spring 53 from being over-stretched and the bottom end of the connecting rod 31 from separating from the long rod 23.

[0045] The outer side of the connecting rod 31 is sleeved with a sleeve 54, and the bottom end of the sleeve 54 is fixed to the device base 1 by welding;

[0046] During operation, a sleeve 54 is sleeved on the outer side of the connecting rod 31 to protect the connecting rod 31 and the connection between the connecting rod 31 and the long rod 23 to prevent the connecting rod 31 and the long rod 23 from bending due to external collision and failing to work normally.

[0047] The connecting spring 37 is sleeved on the outside of the insert rod 36, and the insert rod 36 is welded and fixed inside the sleeve rod 38. The insert rod 36 passes through the bottom ends of the two groups of clamping plates 35 and the sleeve rod 38;

[0048] During operation, the front and rear sides of the insertion rod 36 pass through the bottom end of the clamp plate 35 and the sleeve rod 38. The design of the insertion rod 36 is to guide the clamp plate 35 when it moves, ensuring that the clamp plate 35 can only move along the direction of the insertion rod 36, so that the clamp plate 35 has a better clamping effect on the test sample 57.

[0049] The special-shaped connecting rod 45 is designed in a U-shape, and the connecting plate 49 is designed in an L-shape. Both the special-shaped connecting rod 45 and the connecting plate 49 are in contact with the inner wall of the movable groove 51;

[0050] During operation, the special-shaped connecting rod 45 is designed in a "冂" shape, so that during the process of the moving block 46 driving the first slider 44 to slide in the movable groove 51 through the special-shaped connecting rod 45, the connection between the first slider 44 and the moving block 46 will not interfere with the long rod 23, ensuring the normal movement of the first slider 44. During the movement process, both the special-shaped connecting rod 45 and the connecting plate 49 are in contact with the inner wall of the movable groove 51, so as to achieve the purpose of guiding the movement of the moving block 46 on the second rotating rod 47 and ensuring that the moving block 46 can move stably on the second rotating rod 47.

[0051] On the left and right sides of the inner wall of the cavity 29, cushion blocks 55 are adhesively fixed, and the cushion blocks 55 are made of rubber material;

[0052] During operation, the cushion blocks 55 are made of rubber material and are used to buffer between the transmission rod 25 and the inner wall of the cavity 29, avoiding direct contact between the transmission rod 25 and the inner wall of the cavity 29 when the transmission rod 25 moves to the maximum distance.

[0053] Working principle: First, both ends of the test sample 57 are clamped and fixed by two groups of clamping blocks 22 respectively. Then, one group of clamping blocks 22 is pulled upward by the hanging bracket 21 until the joint of the test sample 57 breaks. At this time, the servo motor 28 is started to drive the first rotating rod 26 to rotate, and then drive the worm 27 to rotate. A group of rotating gears 24 meshing with the worm 27 will be driven. During the rotation of the rotating gear 24 meshing with the worm 27, it will drive the transmission rod 25 to move in the cavity 29 through meshing with the transmission rod 25. Another group of rotating gears 24 meshing with the transmission rod 25 will be driven. At this time, the two groups of rotating gears 24 will rotate in the opposite direction, thereby driving the long rods 23 fixed to them to rotate respectively. The top part of the long rod 23 is connected to the connecting rod 31 through the support spring 53, so it will rotate together with the long rod 23. The connecting rod 31 is connected to the fixed plate 33. When the long rod 23 rotates to the maximum angle, the two fixed plates 33 will rotate to the front and back sides of the test sample 57 at this time. Then, the test sample 57 can be measured through the scale lines on the fixed plate 33. Similarly, when the measurement is completed, the servo motor 28 is rotated in the reverse direction again to drive the fixed plate 33 to rotate. The fixed plate 33 will move away from the test sample 57, so that when the test sample 57 is taken out from the clamping block 22, the fixed plate 33 will not cause obstruction. Thus, the operation of measuring the test sample 57 through the fixed plate 33 is completed.

[0054] In order to prevent the surface of the test sample 57 from bending during the measurement of the test sample 57 by the fixed plate 33, thereby preventing inaccurate measurement results, when the servo motor 28 drives the first rotating rod 26 to rotate, the driving gear 52 fixed on the first rotating rod 26 rotates synchronously, and the second rotating rod 47 is driven to rotate by the engagement of the driving gear 52 with the driven gear 48, and the moving blocks 46 threadedly connected on the left and right sides of the second rotating rod 47 will move in the opposite direction. In the process of the two groups of moving blocks 46 moving away from each other, the first slider 44 and the second slider 50 will be driven to move respectively. When the first slider 44 and the second slider 50 move, they will abut against the ejector rod 41 and push the ejector rod 41 to move upward. The ejector rod 41 will push the sleeve rod 38 upward to move, and the two groups of clamps 35 inserted in the sleeve rod 38 will gradually approach the test sample 57. When the long rod 23 rotates to the maximum angle, the abutment blocks 34 fixed on the fixed plate 33 will clamp the clamps 35. At this time, the clamps 35 clamp and fix the two sides of the test sample 57 to ensure that the test sample 57 can be in a taut state.

[0055] In order to ensure that the fixed plate 33 can be rotated to a position parallel to the test sample 57, sliding rods 40 are fixed on the front and rear sides of the sleeve rod 38, and rubber gaskets 39 are fixed on the sliding rods 40. When the long rod 23 is rotated to the maximum angle, the inner side of the long rod 23 will abut against the rubber gasket 39, and the long rod 23 cannot continue to rotate.

[0056] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
