Description

Technical Field

[0001] This utility model relates to the field of auxiliary support equipment technology, specifically an electrically driven cam linkage support structure for medical devices. Background Technology

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are used directly or indirectly on the human body, including the necessary computer software. Currently, the application of medical devices in medical scenarios is gradually increasing, and the application scenarios they face are becoming increasingly complex. They need to be moved to designated locations and fixed in place in a timely manner, thus requiring auxiliary support devices.

[0003] In the prior art, there are two main types of support and fixation structures for medical devices: one type is fixed installation and cannot be moved after installation, and the other type is movable but requires manual stepping to fix it. This is inconvenient to operate and particularly strenuous when dealing with heavy equipment. It is also difficult to confirm whether the support is in place, which can easily lead to safety accidents. Therefore, there is an urgent need in the field to improve the auxiliary support devices used for medical devices in order to solve the defects of the prior art. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an electrically driven cam linkage support structure for medical devices, which improves the portability and safety of fixing the medical devices after displacement.

Detailed Implementation

[0025] 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.

[0026] Please see Figures 1-6 An electrically driven cam linkage support structure for medical devices includes a base 1 and two support frames 2 for supporting the base 1. The support frames 2 have casters 9 for movement at their lower parts. The base 1 has a telescopic device 3 with a telescopic effect at its lower part. A support member 4 is fixedly installed inside the support frame 2. A bearing seat 5 is provided on the upper part of the support member 4. A main shaft 6 is rotatably connected between the bearing seats 5 between the two support frames 2. The telescopic device 3 drives the main shaft 6 to rotate. A rotating cam 7 is provided on the side of the main shaft 6. A movable column 10 passes through the support member 4. The lower part of the movable column 10 is provided with a support seat 8 for support, and the upper part of the movable column 10 is provided with a baffle 11. An elastic element 12 with elasticity is provided between the baffle 11 and the support member 4. When the rotating cam 7 rotates, it squeezes the baffle 11 to move down. The telescopic end of the telescopic device 3 is fixedly installed with a push rod head 16. One end of the push rod head 16 is rotatably connected to a second connecting rod 17. The other end of the second connecting rod 17 is connected to the side of the main shaft 6. The telescopic device 3 is an electric push rod and is electrically connected to the external control button and the chemical power source. The elastic element 12 is a spring and is sleeved on the side of the movable column 10.

[0027] Specifically, when installing a medical device that needs to be moved, the medical device is fixedly installed on the upper part of the base 1. When the medical device needs to be moved, it is moved by the casters 9. When the medical device needs to be fixed in a specific position, the telescopic device 3 is activated by an external control button. The telescopic end of the telescopic device 3 drives the push rod head 16 to move. The push rod head 16 drives the main shaft 6 to rotate via the second connecting rod 17. The main shaft 6 is supported by several bearing seats 5. When the main shaft 6 rotates, it drives the rotating cam 7 on its side to rotate. The rotating cam 7 and the second connecting rod 17 are both engaged with the main shaft 6 by key pins. When the rotating cam 7 rotates, one side of it presses against the baffle 11. The baffle 11 drives the moving column 10 to move downward, supporting... The seat 8 moves downwards, at which point the elastic element 12 is compressed until the bottoms of several support seats 8 are completely supported on the ground, thus fixing the position of the medical device. By opening the telescopic device 3, the stability of the position of the medical device after movement can be fixed, improving the portability and safety of fixing the medical device after displacement. When the medical device needs to be moved again, the telescopic device 3 is opened again by the external control button switch. The telescopic end of the telescopic device 3 retracts, driving the main shaft 6 to reverse and the rotating cam 7 to reverse. Because the elastic element 12 has elasticity, it pushes the baffle 11 to move upward. The baffle 11 drives the support seat 8 to move upward through the moving column 10. The support seat 8 is separated from the ground, and the medical device can be moved again.

[0028] As a technical optimization of this utility model, a support frame 2 has two support seats 8 at its lower part, and two main shafts 6. A pull rod 13 is provided between the two main shafts 6. Pull rod heads 14 are fixedly installed at both ends of the pull rod 13. A first connecting rod 15 is rotatably connected inside the pull rod head 14, and the other end of the first connecting rod 15 is connected to the side of the main shaft 6. The two main shafts 6 rotate simultaneously under the cooperation of the pull rod 13, the pull rod head 14, and the first connecting rod 15. There are four support seats 8, which improves the stability of the position after the medical device is moved. Moreover, a telescopic device 3 can simultaneously and synchronously control several support seats 8, reducing the cost of use.

[0029] As a technical optimization of this utility model, a connecting column 18 is fixedly installed on the upper part of the support base 8, and a connecting hole 19 adapted to the connecting column 18 is opened at the lower end of the moving column 10. The support base 8 is threadedly connected to the connecting hole 19 through the connecting column 18, which can facilitate the installation or replacement of the support base 8 according to the actual use.

[0030] As a technical optimization of this utility model, the end of the telescopic device 3 away from the main shaft 6 is rotatably connected to the mounting base 20. The mounting base 20 is fixedly installed to the lower part of the base 1 by mounting bolts, which makes it easy to fix the telescopic device 3 to the lower part of the base 1.

[0031] All of the above-mentioned telescopic devices 3 can be purchased from the market. They are mature technologies and have been fully disclosed. Therefore, they will not be described again in the specification. All of the above-mentioned electrical products are equipped with power connection cords, and they are electrically connected to the external main controller and chemical power source through the power cords. The main controller can be a conventional known device such as a computer that plays a control role.

[0032] Finally, it should be noted that in the description of this utility model, the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly.
