Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] See also Figure 1-4 The utility model provides the following technical solutions: a mechanical metering tensile device, including a main body component 1, a hanging ring component 4 is arranged above the main body component 1, a display screen 5 is installed at the central position of the main body component 1, a first switch 2 is installed at the central position of the main body component 1 and below the display screen 5, a second switch 6 is installed at the central position of the main body component 1 and below the display screen 5 and on one side of the first switch 2, a hook 8 is arranged below the main body component 1, the main body component 1 and the hook 8 are connected by a clamping anti-detachment device 3, and the main body component 1 and the hanging ring component 4 are connected by a protective isolation device 7.

[0023] Specifically, the clamping anti-slip device 3 includes a connecting frame 31, a first bidirectional screw rod 32, an anti-slip assembly 33, a connecting plate 34, a screw 35 and a splint 36. The connecting frame 31 is installed on the side of the main body component 1 close to the hook 8. The first bidirectional screw rod 32 is installed on the top of the connecting frame 31 through a bearing. Two splints 36 are installed on the outside of the first bidirectional screw rod 32 and located on the inside of the connecting frame 31 through threads. A connecting plate 34 is installed on the side of the hook 8 close to the connecting frame 31. The connecting frame 31 and the connecting plate 34 are connected by two screws 35. An anti-slip assembly 33 is provided on the top side of the hook 8.

[0024] By adopting the above technical solution, the staff can clamp the objects that are difficult to hang by the cooperation of the first bidirectional screw rod 32 and the clamping plate 36 when necessary, thereby ensuring the normal progress of the tension test.

[0025] Specifically, the height of the inner top surface of the connecting frame 31 is equal to the height of the outer top surface of the clamping plate 36 .

[0026] By adopting the above technical solution, the tensioner can ensure that the inner top surface of the connecting frame 31 and the outer top surface of the clamping plate 36 are in close contact with each other, thereby preventing the clamping plate 36 from rotating and deviating during movement, ensuring normal operation.

[0027] Specifically, the anti-slip assembly 33 includes a vertical plate 331, a screw 332 and a closing plate 333. The closing plate 333 is provided on the top side of the hook 8. The screw 332 is installed on the side of the closing plate 333 away from the top of the hook 8 through a bearing. The vertical plate 331 is installed below the connecting plate 34 and on the outside of the screw 332.

[0028] By adopting the above technical solution, the staff can prevent the objects hanging on the hook 8 from accidentally falling by cooperating with the screw 332 and the closing plate 333 when necessary, thereby ensuring the normal progress of work.

[0029] When the present embodiment is used, when a tensile tester is required for mechanical measurement, the staff hangs the hanging ring assembly 4 in the working position. If the object to be tested can be hung, it is directly hung on the hook 8, and the screw 332 in the anti-slip assembly 33 of the clamping anti-slip device 3 is rotated. The screw 332 is threadedly connected to the vertical plate 331, and the screw 332 is connected to the closing plate 333 by a bearing. The outer top surface of the closing plate 333 and the outer bottom surface of the connecting plate 34 fit each other, so the screw 332 drives the closing plate 333 to move, thereby sealing the hook 8 to prevent the object from accidentally falling off. If the object is difficult to fall off, To hang it, unscrew the two screws 35, remove the connecting plate 34 and the hook 8, and the staff rotates the first two-way screw rod 32. The first two-way screw rod 32 is threadedly connected to the two clamps 36, and the outer top surface of the clamp 36 fits with the inner top surface of the connecting frame 31. Therefore, the first two-way screw rod 32 drives the two clamps 36 to move, and then clamps the object. Then, operate the first switch 2 and the second switch 6 on the main component 1 as needed to perform testing. The display screen 5 can display the results. The work is completed. During the detection process, attention should be paid to the weight of the hook 8 and other structures.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the protective isolation device 7 includes a connecting box 71, a second bidirectional screw rod 72, a moving block 73 and an isolation frame 74. The connecting box 71 is installed between the main body component 1 and the hanging ring component 4. The second bidirectional screw rod 72 is installed at the center of the connecting box 71 through a bearing. Two moving blocks 73 are installed at the outside of the second bidirectional screw rod 72 and at the position inside the connecting box 71 through threads. An isolation frame 74 is installed below the moving block 73.

[0032] By adopting the above technical solution, the staff can protect the display screen 5 and other structures to a certain extent through the cooperation of the second bidirectional screw 72 and the isolation frame 74 when necessary, thereby reducing the possibility of accidental damage to the display screen 5 and other structures.

[0033] Specifically, the height of the inner top surface of the connection box 71 is equal to the height of the outer top surface of the moving block 73 .

[0034] By adopting the above technical solution, the tensioner can ensure that the inner top surface of the connecting box 71 and the outer top surface of the moving block 73 are in close contact with each other, thereby preventing the moving block 73 from rotating and deviating during movement, ensuring normal operation.

[0035] When this embodiment is used, after the inspection is completed, the staff can rotate the second bidirectional screw 72 in the protective isolation device 7. The second bidirectional screw 72 is threadedly connected to the two moving blocks 73, and the outer top surface of the moving block 73 and the inner top surface of the connecting box 71 fit together. Therefore, the second bidirectional screw 72 drives the two moving blocks 73 to move, and then drives the two isolation frames 74 to cover the display screen 5 and other structures, thereby protecting them.

[0036] The structure and principle of the main assembly 1 composed of the first shell, the second shell, the locking mechanism, the convex structure, the sensor, the threaded hole, the first arc-shaped card slot, the concave structure, the cylinder, the second arc-shaped card slot, the battery storage chamber, the back cover, the second connecting column, the transmitter, the fixing block and the spring, the first switch 2, the hanging ring assembly 4 composed of the first connecting column, the hanging ring and the round through hole, the display screen 5, the second switch 6, and the hook 8 have been disclosed in a new type of tensioner for mechanical measurement disclosed in Chinese patent application No. 202420370770.4. The working principle is that when in use, pull the hook, the sensor can detect the tension, and then transmit the tension signal to the transmitter. The transmitter can convert the signal transmitted by the sensor into a numerical signal and display it on the display screen. A first switch and a second switch are provided at the bottom of the display screen. The first switch can turn on and off the tensioner, and the second switch can calibrate and reset. The middle of both sides of the first shell and the middle of both sides of the second shell are locked by a locking mechanism, and the buckle is rotatably connected to the middle of the side of the second shell and can be opened to facilitate disassembly of the first shell and the second shell, and to facilitate repair and replacement of internal parts.

[0037] The working principle and usage process of the present invention are as follows: when a tensile device is needed for mechanical measurement, the staff hangs the hanging ring assembly 4 in the working position. If the object to be tested can be hung, it is directly hung on the hook 8, and the screw 332 in the anti-slip assembly 33 of the clamping anti-slip device 3 is rotated. The screw 332 is threadedly connected to the vertical plate 331, and the screw 332 is bearing-connected to the closing plate 333. The outer top surface of the closing plate 333 and the outer bottom surface of the connecting plate 34 fit together, so the screw 332 drives the closing plate 333 to move, thereby sealing the hook 8 to prevent the object from falling off accidentally. If the object is difficult to hang, unscrew the two screws 35, remove the connecting plate 34 and the hook 8, etc., and the staff rotates the first bidirectional screw rod 32, which is threadedly connected to the two clamping plates 36. The two clamps 36 are connected, and the outer top surface of the clamp 36 fits with the inner top surface of the connecting frame 31, so the first bidirectional screw rod 32 drives the two clamps 36 to move, and then clamps the object. Then, the first switch 2 and the second switch 6 on the main assembly 1 can be operated as needed to perform detection. The display screen 5 can display the result, and the work is completed. During the detection process, attention should be paid to the weight of the hook 8 and other structures; after the detection is completed, the staff can rotate the second bidirectional screw rod 72 in the protective isolation device 7, and the second bidirectional screw rod 72 is threadedly connected to the two moving blocks 73, and the outer top surface of the moving block 73 fits with the inner top surface of the connecting box 71, so the second bidirectional screw rod 72 drives the two moving blocks 73 to move, and then drives the two isolation frames 74 to cover the display screen 5 and other structures, thereby protecting them.
