Description

A lifting structure for medical equipment Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a lifting structure for medical equipment. Background Technology

[0002] In the field of medical equipment, precise and stable lifting functions are crucial. With the continuous development of medical technology, the performance requirements for lifting structures in various medical devices are increasing. Taking imaging instruments as an example, in actual medical operations, because patients vary in height and the imaging sites differ, the imaging equipment must be able to flexibly and precisely adjust its height to ensure the acquisition of high-quality imaging data, while avoiding unnecessary radiation damage to patients or affecting the accuracy of diagnostic results due to inappropriate equipment height.

[0003] Currently, the chain-type lifting structure commonly used in medical equipment has significant defects. The noise generated by the friction and collision of the chain links interferes with the medical environment and medical staff operations, affecting the patient's medical experience. Manufacturing precision, wear, and elastic deformation result in poor lifting accuracy, which cannot meet the high precision requirements of medical equipment projection position. Precise tension adjustment is required during installation, which involves many parts, is difficult and costly, and subsequent maintenance is complex and time-consuming, seriously affecting the efficiency of equipment use. Summary of the Invention

[0004] The purpose of this utility model is to provide a lifting structure for medical equipment, which achieves smooth and precise lifting of the lifting plate through the threaded transmission of the lead screw and bushing. The braking structure composed of an electromagnet, spring, friction block and guide groove fixes the position of the lifting plate, thus solving the problems of poor lifting accuracy and insufficient stability of existing medical equipment lifting structures.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a lifting structure for medical equipment, including a base, a back plate fixedly installed on the top of the base, a lifting plate slidably installed on the back plate, a connecting plate rotatably engaged with the two outer sides of the lifting plate, a friction block rotatably engaged with the end of the connecting plate away from the lifting plate, guide grooves are provided on the two inner sides of the back plate, the guide grooves are slidably engaged with the friction blocks, and friction textures are provided on both contact surfaces of the friction blocks and the guide grooves.

[0007] The present invention is further configured such that the width of the guide groove is greater than the width of the friction block, a spring is fixedly connected between the connecting plate and the lifting plate, and electromagnets are fixedly embedded on both outer sides of the back plate.

[0008] The present invention is further configured such that a mounting plate is fixedly connected to one side of the lifting plate.

[0009] The present invention is further configured such that a drive motor is fixedly installed on the top of the base, a reducer is connected to the output end of the drive motor, a lead screw that penetrates the mounting plate is fixedly connected to the output end of the reducer, a bushing is threadedly connected to the circumferential side of the lead screw, and the bushing is fixedly connected to the mounting plate.

[0010] The present invention is further configured such that the end of the lead screw away from the reducer is rotatably fitted with a top plate fixed to the top of the back plate.

[0011] The present invention is further configured such that two symmetrical guide rods are fixedly connected to the side of the lifting plate near the back plate, and two symmetrical sets of open ball bearing mounting seats are fixedly installed on the side of the back plate near the lifting plate, and one set of the open ball bearing mounting seats slides in cooperation with the guide rod.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model utilizes the threaded engagement between a lead screw and a bushing to achieve the lifting function. The lead screw rotates under the stable drive of the reducer, and the bushing moves linearly along the axis of the lead screw, thereby driving the lifting plate to rise and fall smoothly. Compared with the traditional chain-type lifting structure, it can more accurately control the position of the lifting plate and reduce noise.

[0014] 2. This utility model uses an electromagnet to generate a magnetic field that attracts the friction block, causing it to fit tightly against the guide groove. At the same time, the connecting plate transfers the weight of the lifting plate, the mounting plate, and the medical equipment mounted on it, further pressing the friction block against the guide groove. The friction between the two contact surfaces of the friction block and the guide groove effectively fixes the position of the lifting plate, preventing it from moving randomly due to vibration or external force during use, thus ensuring the safety of medical operations.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023]

[0024] Please refer to Figures 1-3. This utility model is a lifting structure for medical equipment, including a base 1, a back plate 2 fixedly installed on the top of the base 1, a lifting plate 3 slidably installed on the back plate 2, a connecting plate 4 rotatably engaged with the two outer sides of the lifting plate 3, and a friction block 5 (made of ferromagnetic material) rotatably engaged with the end of the connecting plate 4 away from the lifting plate 3. The connecting plate 4 plays a role in force transmission and its own angle is adjustable. Guide grooves 6 are opened on the two inner sides of the back plate 2. The guide grooves 6 are slidably engaged with the friction blocks 5 to provide guidance for the movement of the friction blocks 5. Friction patterns are opened on both contact surfaces of the friction blocks 5 and the guide grooves 6. The design of the friction patterns is based on the principle of friction. By increasing the roughness of the contact surfaces, the friction between the friction blocks 5 and the guide grooves 6 is increased, thereby using this friction to prevent the lifting plate 3 from moving downward.

[0025] Specifically, the guide groove 6 is wider than the friction block 5, providing a certain amount of space for the friction block 5 to move. A spring 7 is fixedly connected between the connecting plate 4 and the lifting plate 3. Electromagnets 8 are fixedly embedded on both outer sides of the back plate 2 (the electromagnets 8 generate a magnetic field when energized based on the principle of electromagnetic induction). The friction block 5 can flexibly adjust its position when attracted by the electromagnet 8 or pulled by the spring 7. When the electromagnet 8 is energized, the generated magnetic field attracts the friction block 5, overcoming the tension of the spring 7, causing the friction block 5 to move closer to the electromagnet 8, thereby making the friction block 5 contact the two friction surfaces of the guide groove 6. When the electromagnet 8 is de-energized, the spring 7 returns to its original deformation, pulling the connecting plate 4, causing the friction block 5 to separate from the two friction surfaces of the guide groove 6.

[0026] A mounting plate 9 is fixedly connected to one side of the lifting plate 3. The mounting plate 9 and the lifting plate 3 are fixedly connected to each other as a whole. According to the installation requirements of different medical devices, specific installation structures, such as mounting holes and slots, are set on the mounting plate 9 to achieve a stable connection with the medical device.

[0027] A drive motor 10 is fixedly installed on the top of the base 1. A reducer 11 is connected to the output end of the drive motor 10. A lead screw 12 that passes through the mounting plate 9 is fixedly connected to the output end of the reducer 11. A bushing 13 is threadedly connected to the circumferential side of the lead screw 12. The bushing 13 is fixedly connected to the mounting plate 9. When the drive motor 10 is powered on, it outputs high-speed rotational mechanical energy. The reducer 11 uses gear transmission to reduce the output speed of the drive motor 10 and increase the torque, providing stable and sufficient power to the lead screw 12. The lead screw 12 and the bushing 13 are threaded together. When the lead screw 12 rotates under the drive of the reducer 11, according to the principle of screw transmission, the bushing 13 will move linearly along the axial direction of the lead screw 12. Since the bushing 13 is fixed to the mounting plate 9, and the mounting plate 9 is connected to the lifting plate 3, the linear movement of the bushing 13 drives the lifting plate 3 to rise and fall, thereby adjusting the height of the medical equipment located on the mounting plate 9.

[0028] The end of the lead screw 12 away from the reducer 11 is rotatably fitted with a top plate 16 fixed to the top of the back plate 2. The top plate 16 is fixed to the top of the back plate 2, providing a stable support point for the lead screw 12, while limiting the axial and radial displacement of the lead screw 12, ensuring the stability and accuracy of the lead screw 12 during rotation.

[0029] Furthermore, two symmetrical guide rods 14 are fixedly connected to the side of the lifting plate 3 near the back plate 2. Two symmetrical sets of open ball bearing mounting seats 15 are fixedly installed on the side of the back plate 2 near the lifting plate 3. One set of open ball bearing mounting seats 15 slides with the guide rods 14. The guide rods 14 are fixed on the lifting plate 3 and move synchronously with the lifting plate 3. The open ball bearing mounting seats 15 are installed on the back plate 2, and the balls inside contact the guide rods 14. Utilizing the principle of rolling friction instead of sliding friction, the balls roll on the surface of the guide rods 14, greatly reducing the friction force when the lifting plate 3 is raised and lowered. The symmetrical arrangement of the guide rods 14 and the open ball bearing mounting seats 15 ensures that the lifting plate 3 receives uniform support force during the raising and lowering process, maintains a balanced state, avoids tilting, further improves the stability and reliability of the entire lifting structure, and ensures the safety of the medical equipment during the raising and lowering process.

[0030] The operation process of this embodiment is as follows: When it is necessary to adjust the height of the medical device mounted on the mounting plate 9, the electromagnet 8 is first de-energized. At this time, the spring 7 returns to its deformation, pulling the connecting plate 4, causing the friction block 5 and the two friction surfaces of the guide groove 6 to separate, reducing the friction force, and releasing the fixed state of the lifting plate 3. At the same time, the drive motor 10 is started. After the drive motor 10 is energized, it outputs high-speed rotating mechanical energy. The reducer 11 connected to its output end uses gear transmission to reduce the output speed of the drive motor 10 and increase the torque, providing stable and sufficient power to the lead screw 12. The lead screw 12 starts to rotate under the drive of the reducer 11. Since the lead screw 12 is threadedly engaged with the bushing 13, according to the principle of screw transmission, the bushing 13 will move linearly along the axial direction of the lead screw 12. Since the bushing 13 is fixed to the mounting plate 9, and the mounting plate 9 is connected to the lifting plate 3, the linear movement of the bushing 13 drives the lifting plate 3 to rise and fall smoothly, thereby adjusting the height of the medical device. When the medical device is adjusted to the appropriate height, the drive motor 10 is turned off and the electromagnet 8 is energized. Electromagnet 8 generates a magnetic field based on the principle of electromagnetic induction, attracting friction block 5. Friction block 5 overcomes the tension of spring 7 and moves closer to electromagnet 8. At the same time, the weight of lifting plate 3 and the medical equipment it carries is transmitted to friction block 5 through connecting plate 4, which together presses friction block 5 into the guide groove 6, so that the two friction surfaces of friction block 5 and guide groove 6 come into contact. Using this friction force, lifting plate 3 is fixed in the current position to prevent it from moving at will and to ensure the stability of medical equipment during use.
