[0001] This utility model relates to the field of rotary freezer technology, and in particular to a detachable double-head rotating mechanism. Background Technology

[0002] A rotary freezer is an instrument widely used in the fields of biology, medicine, and chemistry. It is mainly used for the cryopreservation and processing of samples. With the continuous development of related science and technology, the requirements for the performance and function of rotary freezers are also increasing. In order to better meet different experimental needs and improve the efficiency and quality of sample processing, the structure and function of rotary freezers are constantly being optimized and upgraded. Among them, the detachable double-head rotating mechanism is an important innovative design.

[0003] Before the advent of detachable dual-head rotating mechanisms, the rotating mechanisms of rotary freezers were typically fixed structures, which had several limitations. Fixed single-head rotating mechanisms could only process one sample at a time, resulting in low processing efficiency. When processing different types or sizes of samples, fixed rotating mechanisms were difficult to adapt to and lacked flexibility. Furthermore, maintenance and repair of fixed rotating mechanisms required disassembling the entire rotary freezer, which was complex, time-consuming, and labor-intensive, increasing maintenance costs and equipment downtime. Due to the lengthy disassembly time, the equipment could not operate normally during maintenance, leading to increased downtime, which affected production progress, reduced overall equipment availability and production efficiency, and made it inconvenient for operators. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a detachable double-head rotating mechanism, which aims to improve the existing fixed structure rotating mechanism. During maintenance and repair, the entire double head of the rotary freezer needs to be disassembled, which is complicated, time-consuming and labor-intensive, increasing maintenance costs and equipment downtime. The long disassembly time also leads to inconvenience in use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a detachable double-head rotating mechanism, including a fixed plate, an elongated plate fixedly connected to the bottom rear side of the fixed plate, a servo motor fixedly connected to the front middle of the elongated plate, a horizontal plate fixedly connected to the bottom front side of the fixed plate, the output end of the servo motor passing through the rear side of the horizontal plate and fixedly connected to a transmission wheel, a belt drivingly connecting the outer walls of the two transmission wheels, a connecting column fixedly connected to the front middle of the transmission wheel, a T-shaped column fixedly connected to the front side of the connecting column, multiple oblique grooves opened on the inner side of the T-shaped column, a threaded knob threadedly connected to the rear side of the connecting column, a threaded ring threadedly connected to the outer wall of the threaded knob, a support bar fixedly connected to the front side of the threaded ring, and a pressing block fixedly connected to the front side of the support bar.

[0006] As a further description of the above technical solution:

[0007] A vertical plate is provided on the left side of the fixed plate, and a rotating disk is rotatably connected to the top of the vertical plate. The bottom end of the rotating disk passes through the top of the vertical plate and is fixedly connected to a threaded rod. A movable block is threadedly connected to the outer wall of the threaded rod, and the right side of the movable block is fixedly connected to the left side of the fixed plate.

[0008] As a further description of the above technical solution:

[0009] A connecting post 2 is attached between adjacent extrusion blocks, and an eggplant-shaped bottle is fixedly connected to the front side of the connecting post 2.

[0010] As a further description of the above technical solution:

[0011] A pressing wheel is rotatably connected to the center of the horizontal plate.

[0012] As a further description of the above technical solution:

[0013] A T-shaped knob is threaded onto the top front side of the vertical plate.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the extrusion block is slidably connected to the inner side of the inclined groove.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the pressing wheel is in contact with the top of the outer wall of the belt.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, by cooperating with the connecting column one and the T-shaped column fixedly connected on the transmission wheel, and by twisting the threaded knob connected to the threaded knob on the connecting column one, the inclined groove and the support bar slowly slide upward along the outer wall of the threaded knob, and gradually contact the connecting column two for limiting, so that the eggplant-shaped bottle can be removed.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see the appendix Figure 1 - Appendix Figure 3 One embodiment of this utility model provides a detachable double-headed rotating mechanism, including a fixed plate 13. A long plate 12 is fixedly connected to the bottom rear side of the fixed plate 13. A servo motor 11 is fixedly connected to the front middle of the long plate 12. A horizontal plate 1 is fixedly connected to the bottom front side of the fixed plate 13. The output end of the servo motor 11 passes through the rear side of the horizontal plate 1 and is fixedly connected to a transmission wheel 16. A belt 8 is drivingly connected to the outer walls of the two transmission wheels 16. A connecting belt is fixedly connected to the front middle of the transmission wheels 16. Column 10 is connected to a T-shaped column 17 on its front side. The inner side of the T-shaped column 17 is provided with multiple oblique grooves 21. The rear side of the connecting column 10 is threaded with a threaded knob 20. The outer wall of the threaded knob 20 is threaded with a threaded ring 7. The front side of the threaded ring 7 is fixedly connected with a support bar 19. The front side of the support bar 19 is fixedly connected with a pressing block 18. The middle of the inside of the horizontal plate 1 is rotatably connected with a pressing wheel 6. The outer wall of the pressing block 18 is slidably connected to the inner side of the oblique groove 21.

[0029] Specifically, the servo motor 11 is firmly fixedly connected to the front middle of the elongated plate 12. This servo motor 11 not only provides a power source for the entire device, but also ensures its operational stability and accuracy. At the bottom front of the fixed plate 13, the output end of the servo motor 11 passes through the rear side of the horizontal plate 1 and is firmly connected to the transmission wheel 16, so that the power of the servo motor 11 can be efficiently transmitted to the transmission wheel 16. The outer walls of the two transmission wheels 16 are connected by a taut belt 8. When one transmission wheel 16 rotates, the other transmission wheel 16 will also rotate, thereby realizing the transmission and distribution of power. The threaded knob 20 is threadedly connected to the appropriate position. This threaded knob 20 can not only be adjusted by rotation, but also be fixed and adjusted by the threaded connection with the threaded ring 7.

[0030] Please see the appendix Figure 3 - Appendix Figure 5 A vertical plate 5 is provided on the left side of the fixed plate 13. A rotating disk 4 is rotatably connected to the top of the vertical plate 5. The bottom end of the rotating disk 4 passes through the top of the vertical plate 5 and is fixedly connected to a threaded rod 3. A moving block 2 is threadedly connected to the outer wall of the threaded rod 3. The right side of the moving block 2 is fixedly connected to the left side of the fixed plate 13. A connecting column 2 15 is attached between adjacent extrusion blocks 18. A gizzard-shaped bottle 9 is fixedly connected to the front side of the connecting column 2 15. A T-shaped knob 14 is threadedly connected to the top of the front side of the vertical plate 5. The outer wall of the pressing wheel 6 is attached to the top of the outer wall of the belt 8.

[0031] Specifically, the rotating disk 4 serves as a transmission component and is firmly fixedly connected to the threaded rod 3. This allows the rotation of the rotating disk 4 to drive the threads of the threaded rod 3 to perfectly match the threaded grooves in the moving block 2, enabling the moving block 2 to move stably up and down on the threaded rod 3. The right side of the moving block 2 is fixedly connected to the left side of the fixed plate 13, enhancing the stability of the entire structure and ensuring that the moving block 2 can drive the fixed plate 13 to move together when it moves, thereby realizing the lifting and lowering adjustment of the entire device.

[0032] Working principle: When the double-headed rotating mechanism needs to be disassembled, the connecting column 10 and T-shaped column 17 are fixedly connected to the transmission wheel 16. By turning the threaded knob 20 connected to the connecting column 10, the inclined groove 21 and the support bar 19 slowly slide upward along the outer wall of the threaded knob 20. At the same time, the pressing block 18 moves along the inclined groove 21 on the T-shaped column 17 and gradually contacts the connecting column 15 for limiting, so that the eggplant-shaped bottle 9 can be removed. Therefore, the double-headed rotating mechanism can be quickly disassembled and assembled in a short time, reducing the disassembly and assembly time and meeting the needs of users.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
