[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Please refer to Figures 1-5, an embodiment provided by the present utility model: a convenient assembly type vortex mixer, including a housing 1, a mixing head 4 is arranged above the housing 1, a connecting groove 102 is arranged above the inside of the housing 1, an eccentric disk 6 is arranged at the bottom inside the connecting groove 102, an eccentric seat 7 is fixedly installed on one side above the eccentric disk 6, a connecting rod 8 is fixedly installed below the mixing head 4, and the lower end of the connecting rod 8 is in contact with the eccentric seat 7, a plug-in groove 802 is arranged on the lower end surface of the connecting rod 8, the plug-in groove 802 is arranged as a triangular groove, a plug-in column 10 is arranged inside the plug-in groove 802, and the plug-in column 10 is arranged as a triangular prism, and the plug-in column 10 is welded to the eccentric seat 7.

[0025] During use, when different types of test tubes are used in the vortex mixer and the matching mixing head 4 needs to be replaced, through the plug-in cooperation between the connecting rod 8 below the mixing head 4 and the plug-in column 10 on the eccentric seat 7, the convenience of replacing the mixing head 4 is improved, and the assembly operation is simple, greatly improving the practicability. And the plug-in groove 802 inside the connecting rod 8 is a triangular groove, and the plug-in column 10 is a triangular prism, which improves the transmission stability of the eccentric seat 7 to the mixing head 4 and increases the practicability.

[0026] Furthermore, a power cavity 101 is arranged inside the housing 1, a motor 5 is arranged inside the power cavity 101, and the motor 5 is fixedly connected to the housing 1. The output end of the motor 5 is fixedly connected to the eccentric disk 6, so that the motor 5 can drive the eccentric disk 6 to rotate, which is beneficial to driving the mixing head 4 to rotate for work.

[0027] Furthermore, an outer ring groove 801 is arranged on the outer side of the connecting rod 8. Restricting arc plates 11 are symmetrically arranged on both sides of the connecting rod 8 respectively, and the restricting arc plates 11 are arranged as semi-circular arc plates. The two restricting arc plates 11 are in contact to form a ring, and the center point of the ring is on the same vertical line as the center point of the eccentric disk 6. The restricting arc plates 11 correspond to the outer ring groove 801 in position, and the height dimensions of the restricting arc plates 11 and the outer ring groove 801 match. The inner diameter dimension of the ring formed by the two restricting arc plates 11 is smaller than the maximum diameter dimension of the circumference formed by the connecting rod 8 during eccentric rotation, and the inner diameter dimension of the ring formed by the two restricting arc plates 11 is larger than the maximum diameter dimension of the circumference formed by the rod body inside the outer ring groove 801 of the connecting rod 8 during eccentric rotation. So that during the eccentric rotation of the connecting rod 8, the ring formed by the two restricting arc plates 11 will always be stuck in the outer ring groove 801 of the connecting rod 8, which can restrict the eccentric rotation of the connecting rod 8 and prevent the mixing head 4 from moving up and disengaging during the operation of the vortex mixer, increasing the working stability of the vortex mixer.

[0028] Furthermore, mounting plates 12 are fixedly installed on the outer sides of both of the two limiting arc plates 11. Translation cavities 103 are symmetrically arranged on both sides of the connection groove 102 along the inner part of the housing 1. Translation plates 13 are arranged inside both of the two translation cavities 103. The two translation plates 13 are fixedly connected to the two mounting plates 12 respectively. Thread cavities 1301 are arranged inside both of the two translation plates 13. Threaded rods 14 are threadedly installed inside the thread cavities 1301 of the two translation plates 13. One end of each threaded rod 14 passes through the inner part of the corresponding translation plate 13. Rotating caps 15 are symmetrically rotatably installed on both sides of the housing 1. The two rotating caps 15 are fixedly connected to the two threaded rods 14 respectively. Thus, by rotating the rotating caps 15, the threaded rods 14 are rotated to drive the translation of the translation plates 13. Through the transmission of the mounting plates 12, the movement of the limiting arc plates 11 is driven, which increases the convenience of driving the movement of the limiting arc plates 11.

[0029] Furthermore, a convex cavity 104 is arranged above the translation cavity 103 along the inner part of the housing 1. A convex plate 16 is arranged inside the convex cavity 104. The convex plate 16 is fixedly connected to the translation plate 13. A straight rod 17 is fixedly installed on one side of the convex plate 16. One end of the straight rod 17 extends to the outside of the housing 1. Scale lines are arranged on the outer side of the straight rod 17. During the process of driving the movement of the limiting arc plate 11, by checking the exposed dimension of the scale lines on the straight rod 17, it is convenient to know the movement dimension of the translation plate 13, and further convenient to understand the movement distance of the limiting arc plate 11, which is convenient to accurately drive the movement distance of the limiting arc plate 11 and increases the practicability.

[0030] Furthermore, a backing plate 2 is fixedly installed below the housing 1. A rubber pad 18 is fixedly installed below the backing plate 2. There are four rubber pads 18, and the four rubber pads 18 are respectively arranged at the four corners below the backing plate 2. Due to the damping elasticity of the rubber pads 18 themselves, vibration buffering can be effectively carried out, which increases the working stability of the vortex mixer.

[0031] Furthermore, a magnet 9 is fixedly installed above the insertion slot 802 along the inner part of the connecting rod 8. When the mixing head 4 is assembled, the magnetic attraction of the magnet 9 can magnetically attract and insert the insertion post 10 into the insertion slot 802, which increases the stability of the placement of the mixing head 4. An operation panel 3 is fixedly installed on the front end face of the housing 1, which is convenient for operating the vortex mixer to work and increases the practicability.

[0032] Working principle: When in use, when installing the mixing head 4, align the insertion slot 802 of the connecting rod 8 below the mixing head 4 with the insertion post 10 on the eccentric seat 7 and place it, so that the insertion post 10 is placed into the insertion slot 802 to complete the installation and connection of the mixing head 4, making it convenient to operate when the vortex mixer needs to replace the matching mixing head 4 for different types of test tubes. Then, rotate the rotary caps 15 on both sides of the housing 1 respectively to drive the threaded rods 14 on both sides to rotate, causing the two translation plates 13 to move. Through transmission, the two limiting arc plates 11 are closed to form a ring, which can limit the eccentric rotation of the connecting rod 8 and prevent the mixing head 4 from moving upward and detaching during the operation of the vortex mixer, increasing the working stability of the vortex mixer.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
