Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-3 As shown, a chemical reagent oscillation mechanism includes: a base 100, on which two parallel sliding grooves 101 are provided, and two sliders 102 are slidably connected in each sliding groove 101. A bracket 200 is fixedly connected to the upper end of each slider 102, and a placement groove 201 is provided on the bracket 200. A fixing unit is provided on the bracket 200. An oscillation mechanism and a transmission component for activating the oscillation mechanism are provided at the upper end of the base 100 and on the left side of the bracket 200. The transmission component drives the oscillation mechanism, causing the bracket 200 to move left and right along the sliding grooves 101, which facilitates the oscillation of the chemical reagent in the placement groove 201, allowing the chemical reagent to fully mix together. The fixing unit then clamps and fixes the chemical reagent in the placement groove 201 to prevent collision.

[0025] In this embodiment, as Figure 1 and Figure 2As shown, the oscillation mechanism includes an oscillation bracket 301, on which two sliding rods 302 are fixedly connected. A limiting block 303 is sleeved on the two sliding rods 302. A screw 304 is rotatably connected to the limiting block 303. A moving block 305 is externally threaded onto the screw 304. A circular groove is provided in the middle of the moving block 305, and a ball 306 is fitted into the circular groove of the moving block 305. A rotating shaft 307 is rotatably connected to the oscillation bracket 301. One end of the rotating shaft 307 is fixedly connected to a turntable 308. A circular groove is provided on the surface of the turntable 308. A second ball 309 is connected in the groove. The second ball 309 is fixedly connected to the first ball 306 via a connecting rod 310. When the moving block 305 is in the middle position, rotating the turntable 308 will make the distances of the movement trajectories of the first ball 306 and the second ball 309 equal, and the limiting block 303 will not move. When the screw 304 is rotated, causing the moving block 305 to deviate from the center position, rotating the turntable 308 will make the distances of the movement trajectories of the first ball 306 and the second ball 309 unequal. However, since the second ball 309 and the first ball 306 are fixedly connected via the connecting rod 310, the limiting block 303 will reciprocate along the sliding rod 302, thereby causing the bracket 200 to vibrate.

[0026] In one embodiment, such as Figure 1 As shown, the transmission component includes a first bevel gear 401, which is fixedly connected to the end of the rotating shaft 307 away from the turntable 308. The first bevel gear 401 meshes with a second bevel gear 402, which is fixedly connected to the output end of a transmission motor 403, which is fixedly connected to the upper end of the base 100. When the transmission motor 403 is started, it drives the second bevel gear 402 to rotate, which in turn drives the first bevel gear 401 to rotate. The first bevel gear 401 then drives the rotating shaft 307 to rotate, thereby causing the oscillation mechanism to oscillate.

[0027] In one embodiment, such as Figure 1 As shown, the fixing unit includes two limiting posts 501, and sleeves 502 are respectively sleeved on the two limiting posts 501. A pressure plate 503 is fixedly connected between the two sleeves 502. A locking bolt 504 is threaded on the sleeve 502. The pressure plate 503 presses the test tube downward, causing the sleeve 502 to move downward along the limiting posts 501. The sleeve 502 is fixed by the locking bolt 504, thereby fixing the test tube and preventing collision.

[0028] In one embodiment, such as Figure 1As shown, one end of the screw 304 is fixedly connected to the knob 600. By rotating the knob 600, the screw 304 is driven to rotate, which makes it easier to adjust the distance of the moving block 305 from the center, making it more convenient to use.

[0029] In one embodiment, such as Figure 1 As shown, the limiting block 303 is fixedly connected to the bracket 200 through the connecting plate 700. When the limiting block 303 reciprocates along the slide bar 302, it causes the bracket 200 to vibrate.

[0030] In one embodiment, such as Figure 1 As shown, a sponge pad 800 is fixedly connected to the support 200 to prevent the test tube from being damaged by collision with the support 200 after being subjected to vibration.

[0031] In one embodiment, such as Figure 3 As shown, the anti-slip pad 900 is fixedly connected in the placement groove 201 to increase the friction between the pad and the test tube and to better fix the test tube.

[0032] The above embodiment discloses a chemical reagent shaking mechanism, wherein a test tube is placed in the placement groove 201, the pressure plate 503 presses the test tube downward, driving the sleeve 502 to move downward along the limiting post 501, and the sleeve 502 is fixed by the locking bolt 504, thereby fixing the test tube. The drive motor 403 is started, the drive motor 403 drives the second bevel gear 402 to rotate, the second bevel gear 402 drives the first bevel gear 401 to rotate, the first bevel gear 401 drives the rotating shaft 307 to rotate, and the rotating shaft 307 drives the turntable 308 to rotate. When the moving block 305 is in the middle position, the turntable 308 is rotated, and the sphere... When the distances from sphere 306 to sphere 309 are equal, the limiting block 303 will not move. When the screw 304 is rotated, the moving block 305 is deviated from the center position. When the turntable 308 is rotated, the distances from sphere 306 to sphere 309 are not equal. However, since sphere 309 and sphere 306 are fixedly connected by the connecting rod 310, the limiting block 303 reciprocates along the slide rod 302, thereby causing the bracket 200 to vibrate. As needed, the knob 600 is rotated to rotate the screw 304, adjusting the distance of the moving block 305 from the center, thereby controlling the magnitude of the vibration.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
