Description

Technical Field

[0001] This utility model relates to the field of strength measuring device technology, and in particular to a fiber strength measuring device. Background Technology

[0002] In the field of fiber testing, the sample mounting method of a fiber strength tester has a significant impact on testing accuracy and operational efficiency. To achieve rapid and accurate mounting and positioning of fiber cloth samples, a dedicated strength testing device is typically required. This device usually includes a clamping system, a positioning mechanism, and auxiliary functional modules such as force detection. Especially during high-strength testing, with issues of sample slippage and positioning deviation, the ease of installation and the reliability of fixation of the clamping device directly affect the accuracy and repeatability of test data. Therefore, developing a fiber cloth sample clamping device with rapid installation and easy operation has become an important direction for the technological improvement of materials testing equipment.

[0003] In existing technologies, testing devices used for fiber strength testing generally include a loading frame, a manual clamp, and a force sensor. Structurally, the device includes mechanical clamps for fixing the sample, using bolts or manual pressing to secure the fiber cloth; it also features a scale for roughly positioning the sample. However, in practical use, the lack of a quick-installation function means that the clamp position needs repeated adjustments when changing samples. Furthermore, both the clamping and positioning mechanisms are manually adjustable, making operation cumbersome and time-consuming. This prevents rapid installation and precise positioning of the fiber cloth sample, severely impacting testing efficiency and result accuracy.

[0004] However, existing fiber strength testers still have certain problems in practical applications. Fiber testing requires installation and fixation; in traditional structures, the installation process is overly cumbersome, requiring the disassembly of screws and other fixing devices, thus affecting the efficiency of fiber testing. These problems reduce the efficiency of fiber strength testers and necessitate optimization in structural design. Therefore, a new fiber strength tester is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fiber strength tester, which aims to improve the problem that existing fiber strength testers cannot quickly install and fix fibers, thus affecting the efficiency of fiber testing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fiber strength tester, comprising a base, two sliding strips fixedly connected to the top of the base, a viewing shell fixedly connected to the top of the base, a puller slidably connected inside the sliding strips, a connecting shell fixedly connected to the bottom of the puller, a sliding plate slidably connected inside the sliding strips, a quick-release assembly provided inside the connecting shell, and a quick-opening assembly provided inside the sliding plate.

[0007] The quick-installation assembly includes a rotating column, both ends of which are rotatably connected to the inside of the connecting shell. The rotating column has a first slot and a second slot inside. The connecting shell has two driving columns rotatably connected inside. The outer wall of the connecting shell is fixedly connected to two baffles. Each of the two baffles has a first locking post slidably connected inside. One end of the first locking post is fixedly connected to a pull post. One end of each of the two driving columns is fixedly connected to one end of the rotating column. The outer wall of the first locking post is provided with a fixing component.

[0008] As a further description of the above technical solution:

[0009] The fixing component includes a spring, which is sleeved inside the outer wall of the locking post. One end of the spring is fixedly connected to one end of the pull post, and the other end of the spring is fixedly connected to one end of the baffle.

[0010] As a further description of the above technical solution:

[0011] The quick-opening assembly includes two locking posts, the outer walls of which slide inside the sliding strip.

[0012] As a further description of the above technical solution:

[0013] The sliding plate is rotatably connected to a turntable inside, and a rotator is fixedly connected to the outer wall of the turntable.

[0014] As a further description of the above technical solution:

[0015] Two protruding columns are fixedly connected to the outer wall of the turntable, and each of the two protruding columns is rotatably connected to a rotating ring.

[0016] As a further description of the above technical solution:

[0017] An adjusting bar is fixedly connected to the outer wall of the rotating ring, and an adjusting column is rotatably connected inside the adjusting bar.

[0018] As a further description of the above technical solution:

[0019] The outer wall of the adjusting column is rotatably connected to a second rotating ring, and the outer wall of the second rotating ring is fixedly connected to one end of the second locking column.

[0020] As a further description of the above technical solution:

[0021] A second spring is fitted on the outer wall of the second locking post. One end of the second spring is fixedly connected to the outer wall of the second rotating ring, and the other end of the second spring is fixedly connected to the inside of the sliding plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the fiber is first passed through slot one and slot two in sequence. When the fiber passes through slot two, the pull post is pulled outward, causing slot one to slide outward and stretch spring one, so that slot one exits from the inside of the drive post, releasing its rotational limitation on the drive post. Then, the drive post is rotated, causing the rotating post to rotate, limiting and fixing the fiber to the outer wall of the rotating post. After being wrapped and fixed, the pull post is released, and spring one rebounds, causing slot one to return to the inside of the drive post. This achieves the effect of quickly installing and fixing the fiber, solving the problem that the fiber strength tester cannot quickly install and fix the fiber, affecting the efficiency of fiber testing, and improving the stability of fiber installation in the fiber strength tester.

[0024] 2. In this utility model, the rotary device is first rotated, causing the turntable to rotate inside the sliding plate. The turntable drives the protruding column to rotate. The protruding column converts the rotational motion into the upward motion of the adjusting bar through the first rotating ring. The adjusting bar pushes the adjusting column, and under the synergistic effect of the second rotating ring, the upward motion is converted into the lateral motion of the second locking column. Under the limiting and guiding of the sliding bar, the lateral motion is finally converted into the linear motion of the second locking column, causing it to exit the sliding bar. This achieves the effect of quickly opening the sliding plate, solving the problem that the fiber strength tester cannot quickly open the sliding plate, affecting the fiber installation efficiency, and improving the convenience of fiber installation in the fiber strength tester.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-5This utility model provides an embodiment of a fiber strength tester, comprising a base 1, with two sliding bars 2 fixedly connected to the top of the base 1. The sliding bars 2 serve as guide rails and are made of precision-ground steel with a hard chrome-plated surface to ensure smooth sliding of the puller 4. The base 1 has two sets of upper and lower slots for fixing the sliding plate 23 in the open and closed states (this is common knowledge and will not be described in detail here). A viewing shell 3 is fixedly connected to the top of the base 1. The viewing shell 3 is injection-molded from transparent acrylic material, possessing high light transmittance and impact resistance, facilitating observation of the testing process (this is prior art and will not be described in detail here). The sliding bar 2 is internally connected to a puller 4, which serves as a force-applying mechanism. It is equipped with a high-precision force sensor, which has extremely high measurement accuracy. This is common knowledge and will not be elaborated further here. The bottom of the puller 4 is fixedly connected to a connecting shell 5, which serves as a mounting base for the transmission component. It is equipped with a bearing seat inside to ensure flexible rotation. This is existing technology and will not be elaborated further here. The sliding bar 2 is internally connected to a sliding plate 23. The connecting shell 5 is internally equipped with a quick-installation component for quickly installing and fixing fibers, which improves the efficiency of installation. The sliding plate 23 is internally equipped with a quick-opening component for quickly opening the sliding plate 23 for easy feeding.

[0037] The quick-installation assembly includes a rotating column 6, which engages with slots 12 and 13 for winding motion. By driving column 11, the rotating column 6 rotates, evenly winding the test fiber onto the column surface, achieving rapid fixation of the fiber sample. Both ends of the rotating column 6 are rotatably connected to the inside of the connecting shell 5. Slots 12 and 13 are formed inside the rotating column 6. Slots 12 and 13 are formed by electrical discharge machining and polished to ensure the fiber is not damaged during passage; this is existing technology and will not be elaborated further. Two driving columns 11 are rotatably connected inside the connecting shell 5, and two baffles 7 are fixedly connected to the outer wall of the connecting shell 5. The baffles 7 are formed by laser cutting of steel plates and sandblasted, serving as guide supports for the slots 10; this is common knowledge and will not be elaborated further. Inside plate 7, there are slidingly connected locking pins 10, which act as limit pins. Locking pins 10 are made of bearing steel and have a tapered head to ensure accurate positioning. This is existing technology and will not be described in detail here. One end of locking pin 10 is fixedly connected to a pull post 8. The surface of pull post 8 has anti-slip texture, which conforms to ergonomic design and is easy to operate. This is common knowledge and will not be described in detail here. One end of each of the two driving posts 11 is fixedly connected to one end of the rotating post 6. The outer wall of locking pin 10 is provided with a fixing component, which includes a spring 9. The spring 9 has been stabilized to provide stable reset force and has a service life of tens of thousands of times. This is existing technology and will not be described in detail here. The spring 9 is internally sleeved on the outer wall of locking pin 10. One end of the spring 9 is fixedly connected to one end of the pull post 8, and the other end of the spring 9 is fixedly connected to one end of the baffle 7.

[0038] Reference Figures 6-8 The quick-opening assembly includes two locking posts 22, the outer walls of which slide inside the sliding strip 2. A turntable 15 is rotatably connected inside the sliding plate 23. The turntable 15 rotates in conjunction with a rotator 14. Manually rotating the rotator 14 drives the turntable 15 to rotate, causing the protruding posts 17 to move in a circular motion, thus converting rotational motion into linear motion. The rotator 14 is fixedly connected to the outer wall of the turntable 15, serving as an operating handle. The rotator 14 is made of nylon injection molding with anti-slip textures on the surface, conforming to ergonomic design principles, which is common knowledge and will not be elaborated further here. Two protruding posts 17 are fixedly connected to the outer wall of the turntable 15, serving as power transmission shafts. The protruding posts 17 are precision machined from steel and surface-hardened, exhibiting excellent wear resistance. A rotating ring 18 is rotatably connected to the outer wall of each of the two protruding posts 17, serving as... For the motion transition joint, the rotating ring 18 is made of copper-based powder metallurgy oil-impregnated bearing material, which is self-lubricating and wear-resistant, ensuring flexible rotation. An adjusting bar 16 is fixedly connected to the outer wall of the rotating ring 18. An adjusting column 19 is rotatably connected inside the adjusting bar 16. A rotating ring 20 is rotatably connected to the outer wall of the adjusting column 19. The adjusting bar 16 and the adjusting column 19 perform compound movements. Through the linkage of the rotating ring 20, the swing of the adjusting bar 16 is converted into the linear movement of the locking column 22, achieving the effect of precise control of the locking mechanism. The outer wall of the rotating ring 20 is fixedly connected to one end of the locking column 22. A spring 21 is sleeved on the outer wall of the locking column 22. The spring 21 is made of steel wire and has undergone stress relief treatment to provide stable restoring force. This is existing technology and will not be described in detail here. One end of the spring 21 is fixedly connected to the outer wall of the rotating ring 20, and the other end of the spring 21 is fixedly connected to the inside of the sliding plate 23.

[0039] Working principle: When using this fiber strength tester to install and fix fibers, first open the sliding plate 23 and then pass the fiber through slot 12 and slot 23 in sequence. When the fiber passes through slot 23, pull the pull post 8 outward. The pull post 8 drives the first clamp 10 to slide outward and pulls the spring 9, pulling the first clamp 10 out of the interior of the driving post 11, thereby canceling the rotation limit of the first clamp 10 on the driving post 11. Then rotate the driving post 11, which drives the rotating post 6 to rotate. While rotating the rotating post 6, the limiting rotation is wrapped around the outer wall of the rotating post 6. After the fiber is fixed by being wrapped around the rotating post 6 several times, release the pull post 8. Under the rebound action of the spring 9, the first clamp 10 is reset to the interior of the driving post 11, thereby limiting the rotation of the driving post 11 and achieving the effect of quickly installing and fixing the fiber.

[0040] When it is necessary to open the sliding plate 23, first rotate the rotator 14. The rotator 14 drives the turntable 15 to rotate inside the sliding plate 23. The turntable 15 drives the protruding post 17 to rotate. At the same time, the rotation of the protruding post 17 will drive the first rotating ring 18 to rotate inside the protruding post 17. The rotation of the first rotating ring 18 will convert the rotational motion of the protruding post 17 into the upward motion of the adjusting bar 16. Then, under the adjustment of the adjusting bar 16 and the second rotating ring 20, the upward motion of the adjusting bar 16 is converted into the lateral motion of the second locking post 22. Finally, under the limit of the sliding bar 2, it is converted into the linear motion of the second locking post 22, thereby driving the second locking post 22 to leave the interior of the sliding bar 2, achieving the effect of quickly opening the sliding plate 23.
