[0046] In related technologies, the design and application of lifting mechanisms generally rely on traditional screw-locking mechanisms. While this mechanism plays a fundamental role in securing and removing equipment, its limitations have become increasingly apparent with technological advancements and increasing application demands. In the medical field, in particular, the complex assembly and disassembly procedures can be very inconvenient for users.

[0047] Based on this, Figure 1 、 Figure 2 and Figure 5As shown, an embodiment of the present invention provides a lifting mechanism, including a fixed seat 1, a lifting module and a connecting member 2. The lifting module is arranged on one side of the fixed seat 1 and is detachably connected to the fixed seat 1; the connecting member 2 is used to connect the fixed seat 1 and the lifting module to achieve a detachable connection between the lifting module and the fixed seat 1. The lifting module includes a movable member 4, which can move relative to the fixed seat 1 in a first direction X to switch between a first position and a second position. The movable member 4 is provided with a connecting hole 41, and the connecting hole 41 includes a first sub-hole 411 and a second sub-hole 412 that are interconnected. One end of the connecting member 2 is fixedly connected to the fixed seat 1, and the other end of the connecting member 2 is used to connect to the connecting hole 41 on the movable member 4. The maximum outer diameter of the other end of the connecting member 2 is greater than the aperture of the second sub-hole 412 and less than or equal to the aperture of the first sub-hole 411. When the movable part 4 is in the first position, the other end of the connecting part 2 can be movably inserted into the first sub-hole 411, and the fixed seat 1 and the lifting module are separated; when the movable part 4 is in the second position, the other end of the connecting part 2 can be clamped in the second sub-hole 412, and the fixed seat 1 and the lifting module are locked.

[0048] The lifting mechanism provided by the present invention includes a fixed base 1, a lifting module, and a connecting member 2. The fixed base 1 and the lifting module can be detachably connected via the connecting member 2. The lifting module includes a movable member 4 that can move in a first direction X relative to the fixed base 1 and switch between a first position and a second position.

[0049] The movable part 4 is provided with a connecting hole 41, and the shape of the connecting hole 41 is cleverly designed, including a first sub-hole 411 and a second sub-hole 412 that are interconnected, providing a flexible space for the connecting part 2 to pass through. During the movement of the movable part 4, the other end of the connecting part 2 can move in the first sub-hole 411 and the second sub-hole 412 on the movable part 4. When the movable part 4 is in the first position, the other end of the connecting part 2 can be movably passed through the first sub-hole 411, and the fixed seat 1 and the lifting module are separated; when the movable part 4 is in the second position, the other end of the connecting part 2 can be stuck in the second sub-hole 412, and the fixed seat 1 and the lifting module are locked. This structural design simplifies the operating steps and improves work efficiency. Moreover, by switching the position of the movable part 4, the connection state between the lifting module and the fixed seat 1 can be quickly changed, reducing the possibility of misoperation due to complex operations and improving safety during use.

[0050] Furthermore, the design of the hoisting mechanism provided by this utility model is highly versatile and adaptable to hoisting modules of varying sizes and shapes, enhancing its applicability for hoisting a wide range of medical devices. Furthermore, the simple connection method also facilitates maintenance and inspection of the hoisting mechanism, helping to maintain the long-term stable operation of the equipment. Furthermore, the design of this hoisting mechanism avoids complex mechanical structures and excessive reliance on external tools, effectively reducing production and maintenance costs and improving the product's economical efficiency.

[0051] The following is a detailed description of the various parts of the lifting mechanism provided by the embodiment of the utility model with reference to the accompanying drawings:

[0052] like Figure 1 、 Figure 2 、 Figures 3 to 5 As shown, the present invention provides a lifting mechanism that can be used to secure or move equipment, particularly in the medical field, such as medical devices. The lifting mechanism can be used to secure or move medical equipment to a designated location, or to secure or move components of a medical device to the main unit of the medical device. The lifting mechanism includes a fixing base 1, a lifting module, and a connector 2.

[0053] The main function of the mounting base 1 is to provide a stable support platform for the hoisting module. It can be fixed to the main device or other fixed device to ensure the stability and safety of the hoisting module during operation. The mounting base 1 can be a rectangular plate, a circular plate, or other geometric three-dimensional structure, which is not limited by this invention.

[0054] The lifting module is located on one side of the mounting base 1 and is removably connected to the mounting base 1. Specifically, the mounting base 1 and the lifting module are removably connected via a connector 2. The equipment or component structure to be hoisted can be connected to the lifting module. When the lifting module is connected and locked to the mounting base 1, the equipment or component to be hoisted can be connected and locked to the host computer or other fixed device. When the lifting module is separated from the mounting base 1, the equipment or component to be hoisted can be separated from the host computer or other fixed device.

[0055] The lifting module includes a movable member 4 that can move relative to the fixed base 1 in a first direction X to switch between a first position and a second position. In some embodiments of the present invention, the movable member 4 can be a rod-shaped structure.

[0056] The movable member 4 is provided with a connection hole 41 for the connector 2 to pass through, thereby connecting to the fixed base 1. Accordingly, the fixed base 1 is also provided with a through hole or blind hole for the connector 2 to be inserted into. One end of the connector 2 can be fixedly connected to the fixed base 1, and the other end is used to connect to the movable member 4. Specifically, one end of the connector 2 can be screwed into the through hole or blind hole of the fixed base 1, although this invention is not limited to this.

[0057] The connecting hole 41 includes a first sub-hole 411 and a second sub-hole 412 that are interconnected, and the aperture of the first sub-hole 411 is larger than the aperture of the second sub-hole 412. The other end of the connecting member 2 can be inserted into the connecting hole 41, and the maximum outer diameter of the other end of the connecting member 2 is larger than the aperture of the second sub-hole 412 and is less than or equal to the aperture of the first sub-hole 411. When the movable member 4 moves relative to the fixed seat 1 in the first direction X, the other end of the connecting member 2 can move between the first sub-hole 411 and the second sub-hole 412. Specifically, when the movable member 4 is in the first position, the other end of the connecting member 2 can be movably inserted into the first sub-hole 411. At this time, since the maximum outer diameter of the other end of the connecting member 2 is less than or equal to the aperture of the first sub-hole 411, the other end of the connecting member 2 can be detached from the first sub-hole 411, so that the fixed seat 1 and the lifting module are separated, as shown in FIG. Figure 6 When the movable member 4 is in the second position, the other end of the connecting member 2 can be locked in the second sub-hole 412. Specifically, the other end of the connecting member 2 is also inserted into the second sub-hole 412, but because the maximum outer diameter of the other end is larger than the aperture of the second sub-hole 412, the other end of the connecting member 2 will not be separated from the second sub-hole 412, thereby locking the fixing base 1 and the lifting module. Figure 2 shown.

[0058] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the other end 21 of the connector 2 is in the shape of a mushroom head, and the end of the other end 21 of the connector 2 is the large-diameter head end of the mushroom head. When the movable part 4 is in the first position, the end of the connector 2 in the shape of the mushroom head can be smoothly and freely inserted into or pulled out of the first sub-hole 411 on the movable part 4, thereby realizing the separation of the lifting module from the fixed base 1. When the movable part 4 moves to the second position, the end of the connector 2 in the shape of the mushroom head can be accurately stuck in the second sub-hole 412, ensuring the locking between the fixed base 1 and the lifting module. This design cleverly utilizes the size and shape of the end of the connector 2 in the shape of the mushroom head to achieve rapid loading and unloading of the lifting mechanism while ensuring the safety and convenience of operation.

[0059] Further, if Figures 3 to 5 As shown, the connection hole 41 on the connector 2 is gourd-shaped or teardrop-shaped. The gourd-shaped or teardrop-shaped connection hole 41 is designed to include two hole segments of different diameters, namely a larger hole segment and a smaller hole segment. The larger hole segment is the first sub-hole 411, and the smaller hole segment is the second sub-hole 412. They are interconnected to form a smooth transition area, allowing the connector 2 to move smoothly within the connection hole 41.

[0060] Preferably, the wall of the connecting hole 41 is provided with a guiding bevel 413, and the guiding bevel 413 is provided on the side of the connecting hole 41 close to the connecting member 2, and the guiding bevel 413 is used to guide the connecting member 2 to be inserted into the connecting hole 41. The design of the guiding bevel 413 ensures that the connecting member 2 can engage with the connecting hole 41 on the movable member 4 in a preset and controllable manner. The presence of the guiding bevel 413 reduces the resistance during the insertion of the connecting member 2, making the operation smoother and more precise. At the same time, it also helps to prevent the connecting member 2 from being offset or tilted during the insertion process, ensuring that the connecting member 2 is correctly aligned and smoothly passes through the connecting hole 41, thereby improving the assembly accuracy and reliability of the overall mechanism. In addition, the design of the guiding bevel 413 also takes into account the wear that may occur to the lifting mechanism after long-term use. The presence of the bevel helps to maintain good contact between the connecting member 2 and the movable rod, and maintains the stability and safety of the lifting mechanism even after long-term use.

[0061] like Figures 1 to 3 As shown, in some embodiments of the present invention, the lifting module further includes a control assembly connected to the movable member 4 for controlling the position of the movable member 4 relative to the fixed base 1 so that the movable member 4 switches between the first position and the second position. The control assembly can be an electronic control assembly including an intelligent module or a non-electronic component of a mechanical mechanism.

[0062] In one embodiment, the control assembly includes an elastic member 5 and an operating portion 6. The elastic member 5 is mounted on the movable member 4. Initially, the elastic member 5 is in a compressed state, and the movable member 4 is in a second position due to the elastic force of the elastic member 5. The operating portion 6 is connected to the movable member 4 and is configured to move the movable member 4 in response to an external force, thereby switching the movable member 4 from the second position to the first position.

[0063] Furthermore, a protrusion 42 is provided on the periphery of the movable member 4, one end of the elastic member 5 abuts against the protrusion 42, and the other end of the elastic member 5 remains in a constant position relative to the fixed seat 1 in the first direction X. In this embodiment, the elastic member 5 is in a compressed state in the initial state and has a certain elastic force. When the other end of the elastic member 5 remains in a constant position relative to the fixed seat 1, the end of the elastic member 5 abutting against the protrusion 42 of the movable member 4 will give the protrusion 42 a certain elastic force. Under the action of this elastic force, the movable member 4 is stably in the second position, as shown in FIG. Figure 2 At this time, the other end of the connector 2 is locked in the second sub-hole 412, and the fixing base 1 and the lifting module are locked.

[0064] The operating part 6 can be connected to one end of the movable part 4. Specifically, the operating part 6 can be connected to the movable part 4 via a screw 7. When a certain force is applied to the operating part 6 by the outside, such as when the operator manually operates the operating part 6, a certain force can be applied to the movable part 4. The direction of the force is opposite to the direction of the elastic force applied to the protrusion 42 by the elastic part 5. Under this force, the movable part 4 can overcome the elastic force of the elastic part 5 and switch from the second position to the first position. At this time, the other end of the connecting part 2 can be freely inserted into or withdrawn from the first sub-hole 411, and the fixing base 1 and the lifting module can be separated, such as Figure 6 shown.

[0065] The elastic member 5 may be a spring, which is sleeved on the movable member 4. The operating portion 6 may be a handle or other component that is convenient for the operator to hold, but the present invention does not limit this.

[0066] In some embodiments of the present invention, the lifting module further includes a lifting plate 3 disposed between the fixed base 1 and the movable member 4. The lifting plate 3 is provided with a through-hole 31 through which the connector 2 can pass and enter the connecting hole 41. The lifting plate 3 is immovable relative to the fixed base 1 in the first direction X. In practical applications, the equipment or component to be lifted can be connected to the lifting plate 3, or certain structures of the lifting equipment or component can be directly reused as the lifting plate 3 of the present invention.

[0067] In this embodiment, the movable member 4 is similarly provided with a protrusion 42 on its periphery, against which one end of the elastic member 5 abuts. The hanging plate 3 is provided with a snap-fit ​​portion 32, against which the other end of the elastic member 5 abuts. Specifically, the other end of the elastic member 5 abuts against the snap-fit ​​portion 32 on the hanging plate 3, thereby maintaining its position relative to the fixing base 1 in the first direction X.

[0068] In some embodiments of the present invention, in order to enhance the connection stability between the lifting plate 3 and the movable part 4, the lifting module further includes a fixed ring 8 for connecting the lifting plate 3 and the movable part 4, and the movable part 4 is movably arranged in the fixed ring 8. The shape of the ring in the fixed ring 8 can be set according to the shape of the movable part 4, so that the movable part 4 can stably move in the fixed ring 8 and achieve rapid engagement and separation with the connecting part 2. For example, the movable part 4 is a roughly cylindrical rod-shaped structure, and the ring in the fixed ring 8 can also be designed as a circular ring that matches the shape and size of the movable part 4. The fixed ring 8 can be formed by connecting two semicircular rings, and the two semicircular rings can be connected and fixed by screws 9. The number of fixed rings 8 can be multiple.

[0069] The hoisting mechanism provided by the present invention, when in use, locks the connecting member 2 on the fixed seat 1, and then inserts the hoisting plate 3 into the connecting member 2 through the through hole 31. During the insertion process, the mushroom head structure on the head of the connecting member 2 interacts with the movable member 4, overcoming the elastic force of the elastic member 5 to align the first sub-hole 411 on the movable member 4 with the connecting member 2, that is, the movable member 4 is in the first position. At this time, since the diameter of the mushroom head is less than or equal to the aperture of the first sub-hole 411, the connecting member 2 can pass through the first sub-hole 411. After it passes through the first sub-hole 411, since the other end of the connecting member 2 is in the shape of a mushroom head, the middle section pin rod suddenly decreases, and the movable member 4 changes to the second position under the elastic force of the elastic member 5. Since the diameter of the mushroom head is larger than the second sub-hole 412, the hoisting module can be hoisted on the fixed seat 1 through the connecting member 2 and the movable member 4.

[0070] When disassembly is required, pull the operating part 6 to make the movable part 4 overcome the elastic force of the elastic part 5 and move from the second position to the first position. When the connecting part 2 is aligned with the first sub-hole 411, the lifting module detaches from the connecting part 2 under the action of gravity and completes separation from the fixing base 1.

[0071] The hoisting mechanism provided by the utility model realizes a fast and safe detachable connection through the coordinated work of the fixing seat 1, the hoisting module and the connector 2. This design not only simplifies the operating process and improves work efficiency, but also reduces the risk of misoperation and enhances the safety of use by reducing the complexity of operation. In addition, the design of the hoisting mechanism is highly versatile and adaptable to hoisting modules of various sizes and shapes, which improves its applicability in the field of medical equipment hoisting. The simple connection method simplifies the maintenance and inspection process and contributes to the long-term stable operation of the equipment. At the same time, it avoids the dependence on complex mechanical structures and external tools, effectively reduces production and maintenance costs, and improves the economic efficiency of the product.
