Description

Technical Field

[0001] This utility model relates to the field of tensile probes, and more particularly to a tensile probe for testing the skin of locusts. Background Technology

[0002] Insect body walls serve the dual functions of skin and skeleton in higher animals, providing tight protection and strong support, and offering attachment points for muscles. However, certain areas of the body wall retain softness, such as the lateral membranes connecting the dorsal and ventral plates and the intersegmental membranes between body segments. These soft areas ensure the insect's freedom of movement. To quantify the extensibility of locust intersegmental membranes, reflect the differences in extensibility between male and female locust intersegmental membranes, and understand the effects of target genes on the extensibility of locust intersegmental membranes, a tensile probe can be used to measure the maximum tensile force, fracture strength, and fracture displacement corresponding to the maximum tensile force of the locust intersegmental membrane under external force. This allows for a more intuitive understanding of the tensile properties of locust intersegmental membranes.

[0003] Most existing tensile probes for locust epidermal testing are equipped with a clamping platform and a clamping probe. In use, there is a certain distance between the clamping positions of the clamping platform and the clamping probe. Since locusts are often small in size, the sample is easily deformed when fixing the intersegmental membrane of the locust during epidermal tensile testing, which leads to data distortion and reduces the effectiveness of the tensile probes used for locust epidermal testing.

[0004] Therefore, addressing the problem that most existing tensile probes for locust epidermal testing are equipped with a clamping platform and a clamping probe, which can easily cause sample deformation during epidermal tensile testing when fixing the locust intersegmental membrane, leading to data distortion and reduced effectiveness of the tensile probes for locust epidermal testing, a new tensile probe for locust epidermal testing can be designed. This new probe uses a support platform to hold the texture analyzer body and clamping base. A knob bolt moves the friction fixing seat, and a stop bolt and spring are used to position and support the friction fixing seat. This allows the friction fixing seat to work with the first and second clamping seats to hold the locust, and friction plates protect the locust and improve stability. The epidermal tensile test is then performed through the texture analyzer body. Utility Model Content

The texture analyzer body 5 is installed at the rear end of the support platform 1, and the clamp base 18 is provided at the upper end of the support platform 1. A first clamp seat 19 is installed at the upper end of the clamp base 18, and a second clamp seat 20 is provided at the upper end of the first clamp seat 19. One side end of both the first clamp seat 19 and the second clamp seat 20 is rotatably connected to a stop bolt 21. A spring 22 is provided on the outside of the stop bolt 21. A knob bolt 23 is provided between the two stop bolts 21. One side end of the knob bolt 23 is rotatably connected to a friction fixing device via a rotating shaft. The friction fixing seat 24 is fitted with a clearance bolt 21. Friction plates 25 are installed on one side of the friction fixing seat 24, the first clamp seat 19, and the second clamp seat 20. The upper end of the second clamp seat 20 is rotatably connected to a locking nut 26 via a rotary joint. The upper end of the locking nut 26 is fixed with a set screw 27. The mass structure instrument body 5 and the clamp base 18 are placed on the support platform 1. The friction fixing seat 24 is moved by the knob bolt 23. The friction fixing seat 24 is positioned and supported by the bolt 21 and the spring 22, so that the friction fixing seat 24 can cooperate with the first clamp seat 19 and the second clamp seat 20 to clamp the locust. The friction plates 25 protect the locust and improve its stability.

[0023] Please see Figures 1-3 In this embodiment, the support platform 1 has an inner mounting groove 2, and a power motor 3 is installed at the rear end of the mounting groove 2. A threaded rod 4 is installed on the shaft of the power motor 3 through a coupling. The power motor 3 drives the threaded rod 4 to rotate, thereby moving the other components. The front end of the texture analyzer body 5 is slidably connected to an instrument connecting rod 6. The instrument connecting rod 6 is clearance-fitted with a set screw 27. The instrument connecting rod 6 is installed through the texture analyzer body 5 to facilitate the installation of the second clamp seat 20 through the locking nut 26 and the set screw 27, and to perform tensile testing. A sliding groove 7 is provided on one side end of the support platform 1. A rotating telescopic rod 8 is slidably connected to the inner side of the sliding groove 7. The rotating telescopic rod 8 is installed and moved through the sliding groove 7. The upper end of the rotating telescopic rod 8 is rotatably connected to an extension rod 9 through a rotating shaft. The rear end of the extension rod 9 is rotatably connected to a lens frame 10 through a rotating shaft. The lens frame 10 is moved by rotating the telescopic rod 8 in conjunction with the extension rod 9, so that the user can observe the tensile process.

[0024] Please see Figures 2-3In this embodiment, a movable block 11 is fitted with a clearance on the outer side of the threaded rod 4. The upper end of the movable block 11 is rotatably connected to a mounting plate 12 via a rotating shaft. A rotating seat 13 is fixedly connected to the front end of the mounting plate 12. The movable block 11 and the mounting plate 12 are moved by the threaded rod 4 to move the clamp base 18. A rotating connecting rod 14 is rotatably connected to the inner side of the rotating seat 13. Adjusting rods 15 are fixedly connected to both ends of the rotating connecting rod 14. A rotating frame 16 is installed at the upper end of the rotating connecting rod 14. A pressure rod 17 is installed at the upper end of the rotating frame 16. The rotating connecting rod 14 is rotated by the adjusting rod 15 to rotate the rotating frame 16 and the pressure rod 17. The pressure rod 17 assists in clamping the locust to protect its integrity.

[0025] In use, firstly, the friction fixing seat 24 is moved by the knob bolt 23, and the friction fixing seat 24 is positioned and supported by the plug bolt 21 and the spring 22, so that the flying locust is clamped by the friction fixing seat 24 in conjunction with the first clamp seat 19. Next, the threaded rod 4 is rotated by the power motor 3, and the moving block 11 and the mounting plate 12 are moved by the threaded rod 4, so as to move the clamp base 18. Then, the instrument connecting rod 6 is installed by the texture instrument body 5, so as to install the second clamp seat 20 by the locking nut 26 and the set screw 27. Finally, the friction fixing seat 24 is moved by the knob bolt 23 to cooperate with the second clamp seat 20 to clamp the flying locust, and the exoskeleton stretch test of the flying locust is performed by the texture instrument body 5.

[0026] During testing, the adjusting rod 15 drives the rotating connecting rod 14 to rotate, which in turn drives the rotating frame 16 and the pressure rod 17 to rotate. The pressure rod 17 then helps to clamp the locust to protect its integrity. At the same time, the rotating telescopic rod 8 is installed and moved through the slide groove 7, and the frame 10 is moved by rotating the telescopic rod 8 in conjunction with the extension rod 9, so that the user can observe the stretching process.

[0027] Through the above steps, the texture analyzer body 5 and the fixture base 18 are placed on the support platform 1. The friction fixing seat 24 is moved by the knob bolt 23, and the friction fixing seat 24 is positioned and supported by the plug bolt 21 and the spring 22, so that the friction fixing seat 24 can cooperate with the first fixture seat 19 and the second fixture seat 20 to clamp the locust. The friction plate 25 protects the locust and improves stability. This solves the problem that most existing tensile probes for locust skin testing are equipped with a fixture platform and a fixture probe. In use, there is a certain distance between the clamping positions of the fixture platform and the fixture probe. Since locusts are often small, the sample is easily deformed when fixing the intersegmental membrane of the locust during skin tensile testing, which leads to data distortion and a decrease in the effectiveness of the tensile probe used for locust skin testing.
