[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Depend on Figures 1 to 3 Provided is a vibrating multifunctional test tube rack for medical biological experiments, comprising a base 1, two rotating shafts 11, two hook plates 2, two hooks 21, two inclined surfaces 24, a spring 22, two push rods 23, two limit plates 25 and a vibrating mechanism.

[0036] The two rotating shafts 11 are respectively arranged on both sides of the inside of the base 1, and the two hook plates 2 are respectively rotatably installed on the two rotating shafts 11. The two hooks 21 are respectively arranged at the bottom of the two hook plates 2, and the two inclined surfaces 24 are respectively arranged on the inner sides of the two hooks 21. The two inclined surfaces 24 are symmetrically arranged. Four springs 22 are provided, and the four springs 22 are respectively installed between the two ends of the top ends of the two hook plates 2 and the inner wall of the base 1. Two push rods 23 are slidably installed on both sides of the base 1, and one ends of the two push rods 23 are respectively abutted against the top ends of the two hook plates 2. The two push rods 23 are located above the horizontal plane of the rotating shaft 11. Two limit plates 25 are installed at the bottom of the base 1, and the two limit plates 25 are located on both sides of the two hook plates 2.

[0037] Specifically, the position where the vortex oscillator places the oscillating test tube is a square platform, and the two hook plates 2 correspond to the two sides of the platform. The inclined surface 24 at the bottom of the hook 21 contacts the two side surfaces of the platform, pressing the base 1. The hook plate 2 is squeezed and rotates along the rotating shaft 11, and the hook plate 2 rotates to both sides. When the hook 21 moves downward to the bottom of the platform, the hook 21 loses the abutment of the platform, and the spring 22 presses the hook plate 2, and the hook plate 2 rotates along the rotating shaft 11 to return to the vertical state, and then the two hooks 21 clamp and fix the platform, and the two limit plates 25 limit the other two sides of the platform to prevent the base 1 from being vibrated by the vortex oscillator and the base 1 from falling off from the other two sides of the platform.

[0038] Depend on Figures 4 to 6 It is given that the vibration mechanism is installed inside the base 1, and its function is explained. The vibration mechanism is used when some laboratories do not have or have not purchased a vortex oscillator.

[0039] The vibration mechanism comprises a vibration plate 4, four top springs 41, two groups of eccentric wheel assemblies and four groups of fixing assemblies.

[0040] Four top springs 41 are respectively installed at the four corners of the bottom of the base 1, and the vibration plate 4 is installed on the top of the four top springs 41. The shape of the vibration plate 4 is smaller than that of the base 1, which is convenient for the vibration plate 4 to shake in the base 1.

[0041] Two sets of eccentric wheel assemblies are installed on both sides of the bottom of the base 1 , and the eccentric wheel assembly includes a positioning plate 43 , an eccentric wheel 44 , a fixing block 45 and a motor 46 .

[0042] The positioning plate 43 is installed on the inner bottom wall of the base 1, the eccentric wheel 44 is rotatably installed on one side of the positioning plate 43, the fixing block 45 is arranged at the bottom of the vibration plate 4, the motor 46 is installed on the side of the positioning plate 43 away from the eccentric wheel 44, and the output end of the motor 46 is connected to the eccentric wheel 44; the motor 46 drives the eccentric wheel 44 to rotate, and when the eccentric wheel 44 rotates, the raised side will hit the fixing block 45 during rotation, so that the vibration plate 4 moves horizontally left and right, and the eccentric wheel 44 continues to rotate, and the raised side of the eccentric wheel 44 hits the bottom of the vibration plate 4, and the eccentric wheel 44 pushes the vibration plate 4 to move vertically up and down, thereby causing the vibration plate 4 to vibrate back and forth left and right and up and down.

[0043] The oscillating multifunctional test tube rack for medical and biological experiments further comprises a placing rack 3 , which is mounted on the top of the vibration plate 4 through a fixing assembly.

[0044] Depend on Figures 7 and 8 It is shown that the fixing assembly includes a locking cover 5 , a bolt 51 , a disc vibration groove 52 , a round rod vibration groove 53 and a disc 54 .

[0045] The locking cover 5 is installed on the bottom of the placement frame 3 by bolts 51, the disc vibration groove 52 is opened on one side of the locking cover 5 and the placement frame 3, the round rod vibration groove 53 is opened on one side of the locking cover 5 and the placement frame 3, the disc 54 is arranged on the top of the vibration rod 42, the vibration rod 42 is movably installed in the round rod vibration groove 53, and the disc 54 is movably installed in the disc vibration groove 52; the diameter of the vibration rod 42 is smaller than the inner diameter of the round rod vibration groove 53, and the diameter of the disc 54 is smaller than the disc vibration groove 52. When the vibration plate 4 vibrates, the vibration plate 4 shakes with the vibration rod 42 and the disc 54, and the vibration rod 42 and the disc 54 touch the groove walls of the disc vibration groove 52 and the round rod vibration groove 53 when shaking, thereby causing the placement frame 3 to vibrate.

[0046] Specifically, half of the disc vibration groove 52 and the round rod vibration groove 53 are opened at the top of the locking cover 5, and the other half are opened at the bottom of the placement frame 3. First, the vibration rod 42 and the disc 54 are respectively installed in the disc vibration groove 52 and the round rod vibration groove 53 opened half of the placement frame 3, and then the locking cover 5 is fixed to the bottom of the placement frame 3 with bolts 51. The locking cover 5 limits the vibration rod 42 and the disc 54, which is convenient for installation.

[0047] Depend on Figure 1 and Fig. 9 It is shown that a load-bearing plate 6, a support frame 61, a sleeve groove 62, a sleeve ring 31, a plurality of silicone blocks 32, a buckle assembly and a lifting assembly are installed inside the placement rack 3.

[0048] Depend on Figures 9 and 10 It is shown that the lifting assembly includes two cylinders 8, two lifting plates 81, two sliding grooves 33 and two sliding blocks 82.

[0049] The two sliding grooves 33 are respectively opened on the inner walls on both sides of the placement rack 3, the two cylinders 8 are respectively installed on the bottom of the placement rack 3, the two lifting plates 81 are respectively installed on the top of the output ends of the two cylinders 8, the two sliding blocks 82 are respectively installed on both sides of the supporting plate 6, the bottoms of the two sliding blocks 82 are respectively abutted against the tops of the two lifting plates 81, and the supporting plate 6 is slidably installed inside the placement rack 3.

[0050] The cylinder 8 rises and falls with the lifting plate 81 , and the carrying plate 6 rises and falls following the lifting plate 81 , thereby adjusting the height of the carrying plate 6 to accommodate test tubes or solvent bottles of different heights.

[0051] There are three support brackets 61, which are respectively installed on the inner bottom of the placement rack 3. There are six ferrule rings 31 and six ferrule grooves 62. Three ferrule grooves 62 are opened through one side of the support bracket 61, and the other three are opened on the top of the support bracket 61. The six ferrule rings 31 are respectively installed in the six ferrule grooves 62, and a plurality of silicone blocks 32 are arranged in a circular array on the inner wall of each ferrule ring 31.

[0052] When the test tube or solvent bottle is inserted into the two ferrule rings 31, the two ferrule rings 31 are respectively located at the top and bottom ends of the test tube or solvent bottle, and the silicone block 32 will be squeezed and deformed by the outer wall of the test tube or solvent bottle. Multiple silicone blocks 32 are respectively abutted against the outer wall of the test tube or solvent bottle, thereby fixing the test tube or solvent bottle to prevent the outer wall of the test tube or solvent bottle from shaking.

[0053] Secondly, it is explained that the number of the ferrule rings 31 of the present technical solution is not limited, and can be multiple groups to fix multiple test tubes or solvent bottles, and the diameter part of the ferrule ring 31 is limited. By changing the diameter size of the ferrule ring 31, it can be applied to a variety of test tubes or solvent bottles.

[0054] Depend on Figures 9 and 10 It is shown that the six collar grooves 62 are all threadedly installed with snap-fit ​​assemblies, and the snap-fit ​​assemblies include a holding ring 7 , a snap ring 71 and a snap ring groove 72 .

[0055] The holding ring 7 is threadedly installed in the ring groove 62, the snap ring groove 72 is opened at the top of the clamping ring 31, the snap ring 71 is arranged at the bottom of the holding ring 7, and the snap ring 71 is clamped in the snap ring groove 72, the snap ring 71 presses and limits the clamping ring 31 to fix the clamping ring 31.

[0056] First, install the ferrule ring 31 in the collar groove 62 , and then screw the holding ring 7 into the collar groove 62 . When the holding ring 7 is tightened, the ferrule 71 at the bottom of the holding ring 7 will be inserted into the ferrule groove 72 at the top of the ferrule ring 31 .

[0057] The beneficial effects obtained by the base 1, two rotating shafts 11, two hook plates 2, two hooks 21, two inclined surfaces 24, a spring 22, two push rods 23, two limit plates 25, a vibration mechanism, a placement rack 3, a load-bearing plate 6, a support rack 61, a ring groove 62, a clamping ring 31, a plurality of silicone blocks 32, a buckle assembly and a lifting assembly are as follows: the test tube or solvent bottle can be stably fixed on the placement rack 3, the structure is simple, and the test tube rack can be quickly buckled onto the vortex oscillator by pressing, and multiple liquid test tubes or solvent bottles can be oscillated at the same time, which not only saves oscillation time and frees the hands of the experimenter, but also ensures that the mixing degree of the solutions in the same batch of liquid test tubes is consistent, effectively improves the accuracy of the experiment, and can also achieve the effect of rapid disassembly, which greatly speeds up the oscillation and mixing of the reagents.

[0058] When the utility model is used, the base 1 is pressed, and the hook plate 2 is squeezed and rotates along the rotating shaft 11, and the hook plate 2 rotates to both sides. When the hook 21 moves downward to the bottom of the platform, the hook 21 loses the abutment of the platform, and the spring 22 presses the hook plate 2, and the hook plate 2 rotates along the rotating shaft 11 to return to the vertical state, and then the two hooks 21 clamp and fix the platform, and the two limit plates 25 limit the other two sides of the platform to prevent the base 1 from being vibrated by the vortex oscillator and the base 1 from falling off the other two sides of the platform.

[0059] When the test tube or solvent bottle is inserted into the two ferrule rings 31, the two ferrule rings 31 are respectively located at the top and bottom ends of the test tube or solvent bottle, and the silicone block 32 will be squeezed and deformed by the outer wall of the test tube or solvent bottle. Multiple silicone blocks 32 are respectively abutted against the outer wall of the test tube or solvent bottle, thereby fixing the test tube or solvent bottle to prevent the outer wall of the test tube or solvent bottle from shaking.

[0060] The motor 46 drives the eccentric wheel 44 to rotate. When the eccentric wheel 44 rotates, the raised side will hit the fixed block 45, causing the vibration plate 4 to move horizontally left and right. The eccentric wheel 44 continues to rotate, and the raised side of the eccentric wheel 44 hits the bottom of the vibration plate 4. The eccentric wheel 44 pushes the vibration plate 4 to move vertically up and down, thereby causing the vibration plate 4 to vibrate back and forth left and right and up and down, and the vibration plate 4 vibrates with the placement frame 3.

[0061] The cylinder 8 rises and falls with the lifting plate 81 , and the carrying plate 6 rises and falls following the lifting plate 81 , thereby adjusting the height of the carrying plate 6 to accommodate test tubes or solvent bottles of different heights.
