DETAILED DESCRIPTION

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0032] See also Figure 1-7 In an embodiment of the present invention, a device for scraping saliva from a live pig tongue for animal virus detection includes a base 1 and a horizontal plate 2 movably arranged on the base 1. The two ends of the horizontal plate 2 are connected to two sets of elastic telescopic mechanisms respectively installed on both sides of the base 1, and a pressing piece is provided below the horizontal plate 2, and a gap is reserved between the pressing piece and the base 1 to form a placement area for placing the pig tongue;

[0033] A round roller 3 is also movably arranged above the base 1, and the round roller 3 is connected to a manual driving mechanism installed on the base 1, and the manual driving mechanism is used to drive the round roller 3 to flip, so that the round roller 3 performs a supporting action on the upper jaw of the pig, and the manual driving mechanism cooperates with the elastic telescopic mechanism. When the round roller 3 flips, the elastic telescopic mechanism is triggered to trigger the pressing member to perform a pressing action on the pig tongue;

[0034] The live pig tongue coating saliva scraping device for animal virus detection also includes a scraper 4 movably arranged on the base 1. The scraper 4 is arranged in a "V" shape and is hollow inside. A plurality of through holes 26 for saliva to enter are opened on its inner wall. The scraper 4 is connected to a pulling mechanism installed on the base 1.

[0035] It should be noted that two limiting protrusions 25 are provided at one end of the base 1. In actual use, the user should place the limiting protrusion 25 on the lower gums of the pig. In this way, during the process of scraping saliva, the stability of the device can be ensured and the device can be prevented from falling off the pig's mouth.

[0036] Please refer again Figure 5 The elastic telescopic mechanism includes a guide plate 16 fixedly mounted on the side of the base 1 and a telescopic plate 17 slidably fitted with the guide plate 16, and two groups of elastic members are connected between the telescopic plate 17 and the guide plate 16, and the cross plate 2 is fixed between two of the telescopic plates 17 in the two groups of the elastic telescopic mechanism.

[0037] The elastic member includes a first protrusion 18 and a second protrusion 20 respectively fixed to the side of the telescopic plate 17 and the guide plate 16, a telescopic shaft 19 fixedly mounted on the first protrusion 18, and a cylindrical spring sleeved on the outer circumference of the telescopic shaft 19;

[0038] The end of the telescopic shaft 19 away from the first protrusion 18 passes through the second protrusion 20 and is slidably connected to the second protrusion 20 , and the two ends of the cylindrical spring are respectively connected to the first protrusion 18 and the second protrusion 20 .

[0039] Please refer again Figure 4 and Figure 7 The manual drive mechanism includes a screw rod 9 rotatably mounted at the bottom of the base 1, two guide rods 10 fixedly mounted at the bottom of the base 1, and a translation plate 8 disposed at the bottom of the base 1. The screw rod 9 and the two guide rods 10 all penetrate the translation plate 8, the translation plate 8 is threadedly connected to the screw rod 9, and is slidably connected to the two guide rods 10, and the translation plate 8 is connected to the telescopic plate 17 through a transmission mechanism.

[0040] Furthermore, three through holes are opened on the side of the translation plate 8, and the three through holes are used for the screw rod 9 and the two guide rods 10 to pass through, and the inner wall of the through hole through which the screw rod 9 passes is provided with a thread that engages with the screw rod 9.

[0041] The transmission mechanism includes a first connecting rod 11 fixed to the side of the translation plate 8, a second connecting rod 12 fixed to the first connecting rod 11, and a limiting member 21 fixed to the second connecting rod 12, wherein the limiting member 21 is provided with an inclined surface, and a pulley 22 abutting against the limiting member 21 is also rotatably installed on the side of the telescopic plate 17.

[0042] When in use, after placing the device in the mouth of a live pig, the pig tongue is allowed to enter the placement area (the staff can wear protective gloves and use tweezers to clamp the pig tongue into the placement area). Then, the staff manually rotates the screw rod 9 in the forward direction, and the two guide rods 10 guide the translation plate 8. As a result, the translation plate 8 gradually moves in the direction away from the limiting protrusion 25. Correspondingly, the limiting member 21 moves with the translation plate 8 through the second connecting rod 12 and the first connecting rod 11. In the process of the inclined surface on the limiting member 21 passing through the pulley 22, the telescopic plate 17 gives way and gradually slides toward the inside of the guide plate 16. The telescopic shaft 19 slides on the second protrusion 20, and the cylindrical spring sleeved on the outer periphery of the telescopic shaft 19 is gradually compressed. In this process, the telescopic plate 17 drives the cross plate 2 to move toward the base 1. As a result, the clamping member performs a clamping action on the pig tongue in the placement area to prevent the pig tongue from bending, which makes it difficult to scrape saliva smoothly.

[0043] After the saliva is scraped off, the staff rotates the screw 9 in the opposite direction, so that the translation plate 8 moves toward the limit protrusion 25 and resets. Accordingly, the cylindrical spring on the outer periphery of the telescopic shaft 19 can gradually release its elastic potential energy, so that the cross plate 2 is lifted up and reset, and the clamping state of the clamping piece on the pig tongue is released.

[0044] The clamping member includes a pressing plate 5 arranged at the lower part of the horizontal plate 2 through two elastic sheets 7, one side of the elastic sheet 7 is connected to the horizontal plate 2, and the other side is connected to the pressing plate 5, and a vertical plate 6 is also fixed on the pressing plate 5, and the vertical plate 6 passes through the horizontal plate 2 and is slidably connected to the horizontal plate 2.

[0045] When the telescopic plate 17 drives the horizontal plate 2 to move downward toward the base 1, and after the pressure plate 5 contacts the pig's tongue, as the horizontal plate 2 continues to move, the elastic sheet 7 is deformed, and finally, the pressure plate 5 realizes the effective flexible pressing function of the pig's tongue, which can prevent the pressure plate 5 from pressing down too much and causing damage to the pig's tongue, thereby causing the pig to struggle and making the saliva scraping work difficult.

[0046] Please refer again Figure 1 and Figure 6A deflection plate 14 is rotatably mounted on each side of the base 1, the round roller 3 is rotatably mounted between the two deflection plates 14, and a slide groove 15 is provided on the deflection plate 14. A boss 13 is fixed to one end of the second connecting rod 12 away from the first connecting rod 11, and the boss 13 extends into the slide groove 15 and is slidably connected to the deflection plate 14.

[0047] When the translation plate 8 moves away from the limiting protrusion 25, the boss 13 moves together with the translation plate 8 and slides with the deflection plate 14 through the slide groove 15, so that the deflection plate 14 deflects upward. Accordingly, the round roller 3 will rise upward to support the upper jaw of the pig, so that the pig's mouth remains open, thereby enhancing the smoothness of the subsequent saliva scraping operation.

[0048] Please refer again Figure 3 The pulling mechanism includes a vertical plate 27 which is fixedly mounted on the base 1 and is hollow inside, a slide plate 23 which is slidably arranged in the vertical plate 27, and a pull rod 24 which is slidably arranged on the slide plate 23. The pull rod 24 is arranged in an "L" shape, and its end away from the slide plate 23 is detachably connected to the scraper 4.

[0049] Before the screw rod 9 is rotated forward, that is, before the pressure plate 5 completes the pressing of the pig tongue and the round roller 3 completes the supporting of the upper jaw of the pig, the staff needs to lift the pull rod 24 to lift the scraper 4 to provide space for the pig tongue to enter the placement area. After the pressure plate 5 completes the pressing of the pig tongue and the round roller 3 completes the supporting of the upper jaw of the pig, the pull rod 24 is pressed down by the guidance of the slide plate 23 and the vertical plate 27 until the bottom of the scraper 4 contacts the pig tongue. Then, the pull rod 24 is pulled, so that the scraper 4 moves close to the pig tongue coating to scrape the saliva on the pig tongue coating, and as the saliva accumulates, the saliva will enter the interior of the scraper 4 through the through hole 26 to complete the collection.

[0050] Furthermore, the scraper 4 and the pull rod 24 can be connected by threads, so that after the saliva is scraped, the staff can remove the scraper 4 from the pull rod 24 and then guide the saliva in the scraper 4 for virus detection.

[0051] When the live pig tongue coating saliva scraping device for animal virus detection is implemented, when in use, the device is placed in the mouth of a live pig, and the pig tongue is placed in the placement area (the staff can wear protective gloves and use tweezers to clamp the pig tongue into the placement area), and then the staff manually rotates the screw rod 9 in the forward direction, and the two guide rods 10 guide the translation plate 8, so that the translation plate 8 gradually moves in a direction away from the limiting protrusion 25;

[0052] Correspondingly, the limiting member 21 moves together with the first connecting rod 11 following the translation plate 8 through the second connecting rod 12. When the inclined surface on the limiting member 21 passes through the pulley 22, the telescopic plate 17 gives way and gradually slides toward the inside of the guide plate 16. The telescopic shaft 19 slides on the second protrusion 20, and the cylindrical spring sleeved on the outer periphery of the telescopic shaft 19 is gradually compressed. In this process, the telescopic plate 17 drives the cross plate 2 to move toward the base 1. Therefore, when the telescopic plate 17 drives the cross plate 2 to move downward toward the base 1, and after the pressing plate 5 contacts the pig tongue, as the cross plate 2 continues to move, the elastic sheet 7 is deformed. Finally, the pressing plate 5 realizes the effective flexible pressing function of the pig tongue, which can prevent the pressing plate 5 from being pressed too much and causing damage to the pig tongue, thereby causing the pig to struggle and making it difficult to scrape the saliva.

[0053] When the translation plate 8 moves away from the limiting protrusion 25, the protrusion 13 moves with the translation plate 8 and slides with the deflection plate 14 through the slide groove 15, so that the deflection plate 14 deflects upward. Accordingly, the round roller 3 will rise upward to support the upper jaw of the pig, so that the mouth of the pig remains open, so as to enhance the smoothness of the subsequent saliva scraping operation.

[0054] Before the screw rod 9 is rotated forward, that is, before the pressure plate 5 completes the pressing of the pig tongue and the round roller 3 completes the supporting of the upper jaw of the pig, the staff needs to lift the pull rod 24 to lift the scraper 4 to provide space for the pig tongue to enter the placement area. After the pressure plate 5 completes the pressing of the pig tongue and the round roller 3 completes the supporting of the upper jaw of the pig, the pull rod 24 is pressed down by the guidance of the slide plate 23 and the vertical plate 27 until the bottom of the scraper 4 contacts the pig tongue. Then, the pull rod 24 is pulled, so that the scraper 4 moves close to the pig tongue coating to scrape the saliva on the pig tongue coating, and as the saliva accumulates, the saliva will enter the interior of the scraper 4 through the through hole 26 to complete the collection.
