[0020] The utility model provides an ultrasonic crushing tool. When an ultrasonic crusher is needed to perform operations such as cell crushing or homogenization, emulsification and dispersion on a specified solution, the container containing the specified solution is first placed on a bracket, and then the sound wave generator and the transducer are connected by a connecting line. Then, the transducer and the ultrasonic probe are slid into the installation frame from top to bottom, and the height of the installation frame is adjusted by operating the knob on the installation frame to extend the ultrasonic probe into the solution in the container. The power and duration of the sound wave generator are set, and the sound wave generator is turned on. At this time, the ultrasonic probe generates vibration high-frequency energy in the solution to work. However, this operation will cause the following problems.

The operation is simple and convenient, and the practicability is strong.

[0021] When the ultrasonic crusher is not in use, the ultrasonic probe is easily damaged by accidental contact.

[0032] In the embodiments of the present invention, please refer to Figures 2 to 4The adjusting structure 7 includes a fixed frame 701, which is fixedly connected to the bracket 2. The inner wall of the fixed frame 701 is rotatably connected with a bidirectional screw 702. The arc surface of the bidirectional screw 702 is threadedly connected with two moving plates 703. The two moving plates 703 are slidably connected to the inner wall of the fixed frame 701. The sides of the two moving plates 703 close to each other are fixedly connected with an adjusting frame 706. The adjusting frame 706 is located at one end of the moving plate 703 away from the fixed frame 701. The inner wall of the adjusting frame 706 is fixedly connected with two supporting plates. The arc surfaces of the two support rods 707 are rotatably connected with clamping plates 708. The upper surface of the adjustment frame 706 is threaded with a positioning rod 711. The lower end of the positioning rod 711 is rotatably connected with a positioning plate 712. By using a plurality of pairs of clamping plates 708, containers that cannot be stably placed on the bracket 2, such as test tubes, EP tubes, etc., are clamped and limited. The angles and directions of the two clamping plates 708 in the adjustment frame 706 can be adjusted, and they are used to clamp test tubes with different diameters. The operation is simple and convenient, and the practicability is strong. The movable plate 703 The upper and lower surfaces are rotatably connected to the positions of the fixed frame 701. The arc surface of the pulley 704 is slidably connected to the fixed frame 701.

One side of the fixed frame 701 is fixedly connected to a limiting frame 705. The arc surface of the limiting frame 705 is slidably connected to the moving plate 703. The limiting frame 705 further limits the moving plate 703 so that the moving plate 703 can move more smoothly along the fixed frame 701. The movable plate 703 is more stable when moving along the inner wall of the fixed frame 701. The surface of the clamping plate 708 is fixedly connected with a soft pad 709, which is a rubber pad. The soft pad 709 can effectively prevent the clamping plate 708 from causing damage to the test tube when clamping the test tube. The lower surface of the clamping plate 708 is fixedly connected with a coil spring 710, and the end of the coil spring 710 away from the clamping plate 708 is fixedly connected to the adjustment frame 706. When the clamping plate 708 rotates, the coil spring 710 always gives the clamping plate 708 a torsional force, so that the clamping plate 708 is more stable when rotating;

[0033] In the embodiments of the present invention, please refer to Figure 5 and Figure 6The auxiliary structure 8 includes two clamping rings 81, which are in contact with the transducer 4. The surfaces of the two clamping rings 81 are slidably connected with a support frame 82. The inner wall of the support frame 82 is rotatably connected with an auxiliary rod 83. The arc surface of the auxiliary rod 83 is provided with threads in opposite directions. The arc surface of the auxiliary rod 83 is threadedly connected with the clamping ring 81. A protective frame 85 is fixedly connected to one side of the support frame 82. A baffle 86 is slidably connected to the inner wall of the protective frame 85. A rubber strip 87 is fixedly connected to one side of the baffle 86. The rubber strip 87 is fixedly connected to the rubber strip 88. 7 is interference fit with the inner wall of the protective frame 85, and the support frame 82 is conveniently installed on the transducer 4 by using the clamp ring 81. The baffle plate 86 and the protective frame 85 are used to shield and protect the ultrasonic probe 5. When the ultrasonic probe 5 is not in use, it is effectively protected to prevent it from being damaged by accidental contact. The two clamp rings 81 are fixedly connected to the side close to each other with an anti-skid pad 84, and the surface of the anti-skid pad 84 is provided with a plurality of anti-skid grooves. The anti-skid pad 84 increases the friction on the surface of the clamp ring 81, so that the limiting effect of the clamp ring 81 is better.

[0034] The working principle of an ultrasonic crushing tool provided by the utility model is as follows: when it is necessary to use an ultrasonic crusher to perform operations such as cell crushing or homogenization, emulsification and dispersion on a specified solution, first place the container containing the specified solution on the bracket 2, then use the connecting line 6 to connect the sound wave generator 1 and the transducer 4, and then slide the transducer 4 and the ultrasonic probe 5 from top to bottom into the installation frame 3, operate the knob on the installation frame 3 to adjust the height of the installation frame 3, so that the ultrasonic probe 5 extends into the solution in the container, set the power and duration of the sound wave generator 1, turn on the sound wave generator 1, and then the ultrasonic probe 5 generates vibration high-frequency energy in the solution to work. However, this operation will cause the following problems: When it is necessary to operate the solution in the container such as the test tube and EP tube, since the bottom end of the test tube is in an arc shape, it cannot be directly placed on the bracket 2, and the test tube needs to be fixed with the help of additional tools. In addition, the diameters of different test tubes are different, and the fixing operation is cumbersome, which causes inconvenience to the user. By setting the adjustment structure 7, before installing the transducer 4, the test tube is fixed on the bracket 2, and the positioning rod 711 is rotated first. The positioning rod 711 moves upward along the adjustment frame 706 with the help of the thread. The positioning rod 711 drives the positioning plate 712 away from the clamping plate 708. At this time, the two clamping plates 708 can be rotated to adjust the angle direction of the two clamping plates 708 according to the diameter of the test tube container, and then the positioning rod 7 is rotated in the opposite direction. 11, the positioning rod 711 moves downward with the help of the thread, and the positioning rod 711 drives the positioning plate 712 to squeeze the two clamping plates 708, so that the angle of the clamping plate 708 is fixed. Similarly, the clamping plate 708 on the other adjusting frame 706 is adjusted to abut the bottom end of the test tube against the bracket 2, and the test tube is kept between the two adjusting frames 706. Then the bidirectional screw 702 is rotated, and the bidirectional screw 702 drives the two moving plates 703 to move towards each other at the same time with the help of the thread. The moving plate 703 drives the adjusting frame 706 to move until several clamping plates 708 clamp the test tube, wherein the pulley 704 is used to reduce the friction between the moving plate 703 and the inner wall of the fixed frame 701, so that the moving plate 703 It moves more smoothly along the fixed frame 701, and the movable plate 703 is further limited by the limit frame 705, so that the movable plate 703 is more stable when moving along the inner wall of the fixed frame 701, and the soft pad 709 can effectively prevent the splint 708 from causing damage to the test tube when clamping the test tube. When the splint 708 rotates, the coil spring 710 always gives the splint 708 a torsional force, so that the splint 708 is more stable when rotating, and the containers such as test tubes and EP tubes that cannot be stably placed on the bracket 2 are clamped and limited by using several pairs of splints 708. The angle direction of the two splints 708 in the adjustment frame 706 can be adjusted, which is suitable for clamping test tubes with different diameters. The operation is simple and convenient, and the practicability is strong.

[0035] When the ultrasonic breaker is not in use, the ultrasonic probe 5 is easily damaged by accidental contact. By setting the auxiliary structure 8, the auxiliary rod 83 is first rotated, and the auxiliary rod 83 drives the two clamping rings 81 to move away from each other at the same time by means of the thread, until the two clamping rings 81 are opened to the maximum distance, and then the baffle 86 is slid into the protective frame 85, and the two clamping rings 81 are sleeved on the arc surface of the transducer 4, and the auxiliary rod 83 is rotated in the opposite direction, and the two clamping rings 81 are moved toward each other at the same time by means of the thread until the clamping rings 81 are clamped and fixed. On the transducer 4, the support frame 82 and the protective frame 85 are fixed in position, and the baffle 86 is moved out of the protective frame 85 until the rubber strip 87 on the baffle 86 is inserted into the protective frame 85. The anti-slip pad 84 is used to increase the friction on the surface of the clamp ring 81, so that the limiting effect of the clamp ring 81 is better. The support frame 82 is conveniently installed on the transducer 4 using the clamp ring 81, and the baffle 86 and the protective frame 85 are used to shield and protect the ultrasonic probe 5. When the ultrasonic probe 5 is not in use, it is effectively protected to prevent it from being damaged by accidental contact.
