Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically to a disassembly and assembly structure for a medical device for medical imaging and a medical device lighting device. Background Technology

[0002] Modern large medical equipment (such as CT and MRI scanners) requires lighting devices to alleviate patients' claustrophobia due to their cylindrical apertures. Traditional installation methods involve fixing the lighting device with screws, but the compact internal structure of medical equipment and limited space for tool operation often necessitate special tools or specific angles for installation, leading to low assembly efficiency and difficult maintenance. Screw installation requires two hands, and tools are difficult to access in confined spaces; disassembly is cumbersome, extending equipment maintenance time; and screws are prone to loosening in vibrating environments, posing a risk of falling out.

[0003] Therefore, there is an urgent need for a quick-assembly and disassembly structure for lighting devices that can be quickly assembled and disassembled and can be operated with one hand to improve work efficiency. Utility Model Content

[0008] Optionally, the end of the wedge-shaped surface (12) is connected to the locking hole (11). When the movable part (2) slides to the preset installation position, the plug (31) automatically falls into the locking hole (11) under the action of the spring.

[0009] Optionally, the stop structure (21) and the overlapping mating surface of the front end face (13) of the fixed part (1) constitute a mechanical limit.

[0010] Optionally, the dovetail groove connection structure (4) includes a convex guide rail (14) provided in the fixed part (1) and a concave slide groove (24) provided in the movable part (2).

[0029] Please see Figure 1-4 This application provides a disassembly and assembly structure 100 for a medical device lighting device, comprising: a fixed part 1, which can be fixedly connected to the medical device body; a movable part 2, which is slidably mounted on the fixed part 1, with its first end 20 used to connect to the lighting device 300; and a knob plunger 3, which is mounted on the movable part 2. A dovetail groove connection structure 4 is provided between the fixed part 1 and the movable part 2, and a locking hole 11 is provided on the fixed part 1. The plug head 31 of the knob plunger 3 can be inserted into the locking hole 11 under the action of a spring to achieve locking.

[0030] This assembly / disassembly structure provides a stable base through the fixed connection between the fixed part 1 and the medical device body. The movable part 2 is slidably mounted on the fixed part 1. The dovetail groove connection structure 4 ensures a precisely guided sliding fit between the two. The first end 20 of the movable part is used to connect the lighting device. The first end 20 is provided with one or more openings or screw holes 25, which can be used to fix the lighting device to the first end through bolts or snap-fit ​​interfaces. The knob plunger 3 is installed on the side or top of the movable part 2. Its plug head 31 can move vertically under the bias of the internal spring. The locking hole 11 on the fixed part 1 is located at the end of the sliding path (e.g., the center of the fixed part). When the movable part 2 slides along the dovetail groove to the preset point, the plug head 31 automatically engages with the locking hole 11 under the spring force to form a mechanical lock. Working principle: When the user pushes the movable part 2, the dovetail groove structure 4 guides the linear sliding. When it reaches the locking position, the spring drives the plug head 31 to engage with the hole 11, achieving automatic fixation. To disassemble, pull the knob plunger 3 to release the lock and slide it out in the opposite direction. Technical benefits: Provides a quick and reliable mechanism for assembling and disassembling lighting devices, facilitating maintenance or replacement while ensuring stability and preventing loosening during use. Reasons for this effect: The convex-concave fit of the dovetail joint structure 4 provides high-precision guidance and torsional stability, reducing sliding friction and deviation; the embedded design of the locking hole 11 and the plug 31 achieves self-locking through spring force, enhancing safety and durability and preventing accidental dislodgement.

[0031] In some embodiments, a wedge-shaped surface 12 is provided in the middle of the fixing part 1. The height of the starting end of the wedge-shaped surface 12 is lower than the height of the plug head 31 of the knob plunger 3, which is used to push the plug head 31 upward during installation and guide it to slide into the locking position.

[0032] A wedge-shaped surface 12 is provided in the middle of the fixed part 1. This wedge-shaped surface is sloping, with its initial end lower than the height of the plug head 31 of the knob plunger 3. Therefore, when the movable part 2 is slidably installed, the plug head 31 first contacts the initial end of the wedge-shaped surface 12, is lifted upwards during the sliding process to avoid jamming, and slides smoothly along the slope until it aligns with the locking hole 11. Working principle: The wedge-shaped surface 12 acts as a guide rail, lifting the plug head 31 at the initial stage of installation so that it does not obstruct the sliding, and guiding the plug head to naturally descend and prepare for insertion when approaching the locking point. Technical effect: Simplifies the installation operation. The user only needs to push in one direction to automatically complete the locking preparation, reducing manual adjustment and the risk of error, and improving efficiency. Reason for achieving this effect: The sloping design of the wedge-shaped surface 12 provides a progressive lifting force. The geometry ensures that the plug head 31 smoothly transitions to the locking state under the action of the spring, avoiding hard collisions or misalignment, and improving system reliability.

[0033] In some embodiments, a stop structure 21 is provided at the bottom of the first end of the movable part 2. The height of the stop structure 21 is lower than the height of the starting end of the wedge-shaped surface 12, so that the side of the stop structure 21 and the front end surface 13 of the fixed part 1 form an overlapping mating surface.

[0034] A stop structure 21 is provided at the bottom of the first end of the movable part 2. This stop structure is a protrusion or shoulder, and its bottom surface 211 is lower than the starting end height of the wedge-shaped surface 12. Therefore, during the sliding process of the movable part 2, when the side of the stop structure 21 contacts the front end face 13 of the fixed part 1, an overlapping mating surface is formed, providing physical limitation. Working principle: The stop structure 21 fits against the front end face of the fixed part 1 at the sliding endpoint, limiting the further displacement of the movable part 2 and ensuring its accurate position. Technical effect: Prevents excessive sliding or displacement of the movable part 2, ensures accurate alignment of the locking mechanism, and improves installation accuracy and stability. Reason for achieving this effect: The low height design of the stop structure 21 avoids interfering with the guiding function of the wedge-shaped surface 12, and at the same time, the overlapping mating with the front end face of the fixed part 1 forms a rigid block, eliminating positional errors through mechanical constraint.

[0035] In some embodiments, the end of the wedge-shaped surface 12 is connected to the locking hole 11. When the movable part 2 slides to the preset installation position, the plug 31 automatically falls into the locking hole 11 under the action of the spring.

[0036] The end of the wedge-shaped surface 12 is directly connected to the locking hole 11, forming a continuous path. When the movable part 2 slides to the preset installation position (limited by a stop structure, etc.), the plug 31 slides along the wedge-shaped surface 12 to the end, and the spring force drives it to automatically fall into the locking hole 11 to complete the locking. Working principle: The end of the wedge-shaped surface 12 serves as a transition zone, guiding the plug 31 from the raised state directly into the locking hole 11 without additional operation. Technical effect: Achieves one-button automatic locking, reduces user intervention, and improves installation speed and reliability. Reason for achieving this effect: The connection design between the wedge-shaped surface 12 and the locking hole 11 ensures geometric continuity, and the spring force provides a constant bias pressure, allowing the plug 31 to naturally embed when it reaches the position, eliminating the need for manual alignment.

[0037] In some embodiments, the stop structure 21 and the overlapping mating surface of the front end face of the fixed part 1 form a mechanical limit to prevent the movable part 2 from displacing in the non-installation direction.

[0038] The stop structure 21 and the overlapping mating surface of the front end face of the fixed part 1 form a rigid mechanical limit. When the movable part 2 slides to its end point, this mating surface is in tight contact, preventing the movable part 2 from non-installation displacement in the lateral or vertical directions. Working principle: The limiting surface physically constrains the degrees of freedom of the movable part 2, allowing it to slide only in the installation / removal direction. Technical effect: Enhances structural stability, prevents vibration or displacement of the lighting device during use, and ensures long-term reliability. Reason for achieving this effect: The overlapping mating surface provides a large contact area, geometrically locking non-installation direction movement through friction, simplifying design and improving anti-interference capabilities.

[0039] In some embodiments, the dovetail groove connection structure 4 includes a convex guide rail 14 provided in the fixed part 1 and a concave slide groove 24 provided in the movable part 2, with a clearance fit of less than 0.5 mm between the two.

[0040] The dovetail groove connection structure 4 consists of a convex guide rail 14 on the fixed part 1 and a concave slide groove 24 on the movable part 2. The clearance between the two is less than 0.5mm, ensuring a tight fit between the guide rail 14 and the slide groove 24 while allowing for sliding. Working principle: The convex guide rail 14 is embedded in the concave slide groove 24. The small clearance design allows for smooth linear movement while limiting radial displacement. Technical effect: Provides high-precision guidance, reduces sliding friction and wear, and extends service life. Reason for achieving this effect: The clearance of less than 0.5mm ensures minimum tolerance; the convex and concave shapes increase the contact area, improve rigidity and alignment accuracy, and prevent wobbling.

[0041] In some embodiments, the manual operation part 32 of the knob plunger 3 is exposed on the upper surface of the movable part 2, and the engagement between the plunger head 31 and the locking hole 11 is released by vertical pulling. Optionally, the knob plunger 3 needs to be rotated at a certain angle before being pulled to release the lock.

[0042] The manual operating part 32 of the knob plunger 3 is exposed on the upper surface of the movable part 2, allowing the user to pull it vertically to overcome the spring force and pull the plug head 31 out of the locking hole 11, thus releasing the lock. Working principle: When the user pulls the operating part 32, the plug head 31 moves vertically upwards and disengages from the locking hole 11, allowing the movable part 2 to slide freely. Technical effect: Simplifies disassembly operations, can be completed with one hand, and improves maintenance convenience. Reason for achieving this effect: The exposed design of the operating part 32 provides easy access, and the vertical pulling action directly controls the locking state, reducing operational complexity.

[0043] In some embodiments, a groove 15 is provided in the middle region of the convex guide rail 14, and the locking hole 11 is provided in the groove 15.

[0044] A groove 15 is provided in the middle area of ​​the convex guide rail 14, and a locking hole 11 is located within this groove 15, thus the locking hole 11 is embedded in the guide rail structure. Working principle: The groove 15 provides accommodating space; when the movable part 2 slides to the groove position, the locking hole 11 aligns with the path of the plug 31. Technical effect: It protects the locking hole 11 from external impacts and ensures that the plug 31 is flush with the guide rail when embedded, avoiding interference from protrusions. Reason for achieving this effect: The recessed design of the groove 15 integrates the locking hole 11, maintaining the flatness of the guide rail surface and improving structural compactness and safety.

[0045] In some embodiments, the knob plunger 3 is a spring pin or a ball plunger, the elastic component of which provides biasing force toward the locking hole 11.

[0046] The knob plunger 3 can be a spring pin or a ball plunger type, with an internal elastic component (such as a coil spring) providing a continuous biasing force toward the locking hole 11, driving the plug head 31 to automatically engage. Working principle: The elastic component applies a downward or radial force when the plug head 31 is not pulled up, ensuring that the plug head 31 tends toward the locking hole 11 in a free state. Technical effect: Achieves automatic reset and reliable locking, reducing manual intervention. Reason for achieving this effect: The inherent elasticity of the elastic component provides a constant biasing force, ensuring that the plug head 31 responds quickly to position changes, improving locking efficiency.

[0047] Another embodiment of this application corresponds to a medical device, including a medical device body 200, the medical device body 200 including a cavity 201 extending along the longitudinal direction, the medical device also including the above-mentioned disassembly and assembly structure 100, the disassembly and assembly structure is arranged on the outside of the medical device body, and the fixed part 1 is connected to the medical device body, the middle part of the lighting device 300 is connected to the movable part 2, and the fixed part 1 and the movable part 2 are detachably connected.

[0048] This medical device comprises a medical device body 200 and a longitudinally extending cavity 201. A detachable structure is arranged within the medical device body 200. A fixed part 1 is fixedly connected to the medical device body by screws or clips. The lighting device (such as an LED module) is connected in the middle to the first end 20 of a movable part 2, which is detachably connected to the fixed part 1. Working principle: By sliding the movable part 2, the lighting device can be easily installed or removed from the cavity, and a rotary plunger 3 locks it in place. Technical benefits: Facilitates the maintenance and upgrade of the medical device's lighting system, reducing downtime. Reasons for achieving this effect: The modular design of the detachable structure is integrated into the cavity; the stable connection of the fixed part 1 and the sliding nature of the movable part 2 provide flexibility, ensuring quick replacement of the lighting device.

[0049] In some embodiments, the number of lighting devices 300 is one or more. Each lighting device includes an arc-shaped support 301 and a light strip 302 or LED beads disposed on the support. The medical device body 200 has a light-transmitting structure 202 or a window, and the lighting device is located outside the light-transmitting structure 202 or window, allowing light to pass through it. Optionally, when there are two lighting devices 300, the two lighting devices can be symmetrically distributed on the medical device body.

[0050] In some embodiments, the fixed part 1 and the movable part 2 are detachably connected, including: aligning the dovetail groove structure 4 of the movable part 2 with the guide rail of the fixed part 1; pushing the movable part 2 along the guide rail direction to raise the knob plunger head 31 along the wedge-shaped surface 12; when the movable part 2 slides to the point where the stop structure 21 contacts the front end face of the fixed part 1, the plug head 31 automatically falls into the locking hole 11 to complete the locking; during disassembly, the knob plunger 3 is vertically pulled up and the movable part 2 is slid in the opposite direction.

[0051] The above describes the disassembly and connection operation of the fixed part 1 and the movable part 2: Step 1, align the dovetail groove structure 4 of the movable part 2 with the guide rail of the fixed part 1 to ensure the initial position is correct; Step 2, push the movable part 2 along the guide rail direction. During the pushing process, the plug 31 contacts the wedge surface 12. Because the initial end is low, the plug 31 is lifted upward to avoid collision; Step 3, when the movable part 2 slides to the point where the stop structure 21 contacts the front end face of the fixed part 1, the plug 31 aligns with the locking hole 11 and automatically falls in under the action of the spring to complete the locking; During disassembly, vertically pull the operating part of the knob plunger 3 to disengage the plug 31 from the locking hole 11, and then slide the movable part 2 in the opposite direction to remove it. Overall principle: Utilizing the ramp guidance of the wedge surface 12 and the limiting of the stop structure 21, combined with the spring force, a semi-automatic locking is achieved, reducing the need for manual alignment. Technical effect: Provides a fast and intuitive disassembly and assembly process, reduces the error rate of operation, and improves maintenance efficiency. The reason for achieving this effect is: the method and steps are optimized, the wedge surface 12 and the stop structure 21 ensure the path is accurate, the spring force drives automatic locking, and the user's actions are simplified.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
