[0002] Medical ring pendant is an important device to improve the efficiency of medical equipment in modern medical environment. It is mainly used in hospital operating rooms, ICU and other places that require efficient and flexible medical equipment support. Through the ring design, the medical ring pendant can make better use of space and provide medical staff with a more convenient and efficient medical equipment operation environment. In order to meet various medical needs in the ward, the pendant is usually installed on the ceiling for use.

[0003] A conventional ring-shaped tower crane is mainly composed of a ring-shaped hanging rail and an adjusting rod, wherein the adjusting rod can rotate circumferentially relative to the ring-shaped hanging rail for compatibility with the installation of different accessories. However, although the adjusting rod currently used can be adjusted in length and rotate circumferentially, it cannot be expanded or retracted. It occupies a large space when not in use, has limited compatibility, and cannot adapt to the installation of more accessories.

[0004] At the same time, a plurality of adjustment rods are usually installed on the annular tower for installing accessories. The adjustment rods currently used mainly include multi-stage adjustment and stepless adjustment. The multi-stage adjustment can only be adjusted in multiple gears, and although the stepless adjustment can be adjusted steplessly within a certain height range, it usually requires manual operation and adjustment by turning the screw. The adjustment process is relatively cumbersome and urgently needs to be improved. Summary of the invention

[0005] The object of the present invention is to provide a retractable and adjustable medical annular pendant and an adjustment method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned objectives, the present invention provides the following technical solutions: a medical annular hanging tower that can be folded and adjusted, comprising an annular hanging rail, the outer side surface of the annular hanging rail is provided with fixed ear plates at equal angles, the bottom end of the annular hanging rail is provided with a mounting seat, the outer side surface of the mounting seat is provided with an extension guide rail fixedly installed at equal angles, the interior of the extension guide rail is movably clamped with a guide block, the bottom end of the guide block is fixedly installed with an adjustment component, the side of the guide block away from the mounting seat is fixedly installed with a storage enclosure located on the side of the adjustment component, the bottom end of the mounting seat is provided with a manipulation component, the top of the manipulation component is connected to the middle part of the bottom end of the guide block, the guide blocks are distributed at equal angles above the manipulation component, the middle part of the top end of the mounting seat is fixedly installed with a support rod, the mounting seat is movably clamped with the annular hanging rail through the support rod, and the support rod rotates relative to the annular hanging rail.

[0007] In actual use, the device can be suspended between the ceiling through the fixed ear plate on the outer side of the circular hanging rail. At the same time, in the initial state, the device is in the storage state, that is, the operating component is at the lowest point. At the same time, by pulling any adjustment component, the adjustment component can be driven to rotate relative to the circular hanging rail to complete the circumferential adjustment process to adapt to the installation of different accessories. After the adjustment is completed, the accessories can be installed at the bottom of the adjustment component for easy use. As a further technical solution of the present invention, the operating assembly includes an operating rod, a movable seat is fixedly installed in the middle of the top end of the operating rod, and a first fixed seat is fixedly installed at an equal angle on the top end of the movable seat.

[0008] As a further technical solution of the present invention, one end of the first fixed seat away from the joystick is movably connected to a connecting rod via a rotating shaft, and one end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat via a rotating shaft, and the top end of the second fixed seat is connected to the bottom end of the guide block.

[0009] When the horizontal position of the adjustment component does not meet the needs of the accessory, the joystick and the movable seat can be driven to move upward by pushing the joystick upward, and the first fixed seat can be driven to move upward simultaneously. At this time, multiple connecting rods are then subjected to thrust, which can drive multiple connecting rods to deflect toward the outer side surface, and apply thrust to the second fixed seat and the guide block. At this time, the guide block can be displaced relative to the extended guide rail, and drive multiple adjustment components to move toward the outer side surface of the extended guide rail to complete the adjustment of the horizontal position.

[0010] By controlling the up and down displacement of the joystick, the horizontal position of multiple guide blocks can be quickly adjusted, and then the horizontal position of multiple adjustment components can be adjusted. The entire adjustment process can be completed in one step, so that the device can quickly complete the horizontal position adjustment of multiple adjustment components while supporting rotation and height adjustment, meeting the installation requirements of different accessories and significantly improving the compatibility of the device.

[0011] When the device is no longer in use, the joystick can be pulled downward, and the joystick and the movable seat will drop accordingly until the movable seat drops to the lowest point. At this time, multiple connecting rods will then be relatively close to each other, and an inward pulling force can be applied to the guide block until multiple adjustment components and storage enclosures are driven relatively close to each other. At this time, multiple storage enclosures will then approach each other until they form a cylindrical shape to block the internal adjustment components, completing the storage process and reducing the occupied space.

[0012] By utilizing the process of adjusting the horizontal position of the device, the adjustment component can be quickly retracted through the adjustment and reset process of the operating component, and the adjustment component can be blocked and protected by the storage panel on the outer side, so that the occupied space can be reduced and the interference of the device to the external environment can be prevented, which significantly improves the overall practicality of the device and reduces the environmental interference when not in use. As a further technical solution of the present invention, the adjustment component includes a fixed tube, the top end of the fixed tube is connected to the bottom end of the guide block, the internal movable sleeve of the fixed tube is connected with a movable inner tube, the movable inner tube moves up and down relative to the fixed tube, the top end of the movable inner tube is fixedly installed with a limiting tube, and the movable inner tube is connected to the inside of the limiting tube.

[0013] As a further technical solution of the present invention, the internal movable sleeve of the movable inner tube is provided with an adjusting rod, the bottom end of the adjusting rod passes through the bottom end of the movable inner tube and is fixedly connected with a hook, the adjusting rod passes through the top end of the movable inner tube and the top end of the limiting tube in sequence, and is fixedly connected with a mounting plate located above the limiting tube.

[0014] As a further technical solution of the present invention, a limit plate located inside the limit tube is fixedly installed on the outer side surface of the adjusting rod near the top end, and a limit spring located inside the limit tube is fixedly installed on the outer side surface of the adjusting rod, and the upper and lower ends of the limit spring are respectively connected to the top end of the inner cavity of the limit tube and the top end of the limit plate.

[0015] As a further technical solution of the present invention, a limiting guide rail is fixedly installed at an equal angle on the top of the limiting tube, and a fourth fixing seat is movably connected to the top of the limiting guide rail. The fourth fixing seat is located inside the limiting guide rail and a supporting rubber block is fixedly installed on one side close to the inner wall of the fixed tube.

[0016] As a further technical solution of the present invention, a third fixed seat is fixedly installed at an equal angle at the bottom end of the mounting plate, and the end of the third fixed seat away from the mounting plate is movably connected to a support rod through a rotating shaft, and the end of the support rod away from the third fixed seat is movably connected to a fourth fixed seat.

[0017] As a further technical solution of the present invention, when the limit spring is in an initial state, the mounting plate is at the highest point, and the outer side surface of the supporting rubber block is in contact with the inner side wall of the fixing tube.

[0018] When the overall length of the adjustment assembly cannot meet the height requirement, the adjustment rod can be pressed upward to make the adjustment rod move upward relative to the movable inner tube. At this time, the adjustment rod can drive the limit plate and the mounting plate to move upward. At this time, the limit spring is compressed. At the same time, when the mounting plate moves upward, it can drive the multiple support rods to deflect toward the middle and apply tension to the multiple fourth fixing seats. At this time, the multiple fourth fixing seats are relatively close to each other, and drive the supporting rubber blocks to be relatively close to release the release between them and the inner wall of the fixed tube. At this time, the limit of the movable inner tube is released, and the movable inner tube can be pulled downward to increase the overall length of the adjustment assembly. When the appropriate length is adjusted, the pressure on the adjusting rod can be stopped. At this time, the limit spring can be automatically reset and drive the limit plate and the mounting plate to move downward. At this time, multiple support rods are automatically reset and deflected toward the inner wall of the fixed tube, while driving multiple supporting rubber blocks to approach the inner wall of the fixed tube until they contact the inner wall, completing the limit fixing process and finally completing the height adjustment.

[0019] The overall length adjustment of the adjustment component can be quickly achieved by utilizing a simple pressing and pulling-down process, and only one hand is required during the adjustment process, that is, it can be achieved by pressing with the thumb and pulling down with the fingers. The whole process is completed quickly without the assistance of both hands, and stepless adjustment can be achieved, avoiding the problems of the traditional device's stepless adjustment being unchanged and the multi-stage adjustment being unable to achieve fixation at different heights, thereby improving the convenience of adjustment.

[0020] A method for adjusting a retractable and adjustable medical annular pendant comprises the following steps: S1: When the horizontal position of the device needs to be adjusted, the joystick can be directly pushed upward, and the movable seat and the first fixed seat rise accordingly, driving the multiple connecting rods to deflect toward the outer side surface, thereby applying thrust to the guide block, so that the multiple guide blocks move toward the outer side surface; S2: At this time, multiple adjustment components and storage panels can be expanded outward at the same time to change the horizontal position of the adjustment components for installing different accessories. Conversely, the joystick can be pulled downward, and multiple connecting rods can be retracted inward at the same time, which can drive multiple adjustment components to move closer to the middle. At the same time, multiple storage panels are relatively close until they form a cylindrical shape, completing the adjustment process; S3: When the length of the adjustment assembly needs to be adjusted, the adjustment rod can be pressed upward and the movable inner tube can be pulled downward. When the adjustment rod moves upward relative to the movable inner tube, the mounting plate moves upward accordingly, which can drive the multiple support rods to deflect toward the middle, and finally drive the multiple support rubber blocks to shrink inward at the same time, releasing the contact with the inner wall of the fixed tube. At this time, the limit of the movable inner tube is released, and the movable inner tube can be pulled downward; S4: When it is adjusted to the appropriate position, the pressure on the adjusting rod can be released, and the limit spring will be reset accordingly, which can drive the mounting plate to automatically reset, and the supporting rubber block to automatically reset and contact with the fixed tube, completing the limit with the fixed tube and completing the adjustment process.

[0021] The beneficial effects of the present invention are as follows: 1. The present invention can quickly adjust the horizontal positions of multiple guide blocks and then adjust the horizontal positions of multiple adjustment components by controlling the up and down displacement of the joystick. The entire adjustment process can be completed in one step, so that the device can quickly complete the horizontal position adjustment of multiple adjustment components while supporting rotation and height adjustment, meet the installation requirements of different accessories, and significantly improve the compatibility of the device.

[0022] 2. The present invention can quickly adjust the overall length of the adjustment component by utilizing a simple pressing and pulling downward process, and it can be completed with one hand during the adjustment process, that is, it can be achieved by pressing the thumb and pulling down the fingers. The whole process is completed quickly without the assistance of both hands, and stepless adjustment can be achieved, avoiding the problems of the traditional device's stepless adjustment being unchanged and the multi-stage adjustment being unable to achieve different height fixation, thereby improving the convenience of adjustment.

[0023] 3. The present invention utilizes the process of adjusting the horizontal position of the device, and realizes the rapid retraction of the adjustment component through the adjustment and resetting process of the operating component, and blocks and protects the adjustment component through the storage enclosure on the outer side, thereby reducing the occupied space and preventing the device from interfering with the external environment, thereby significantly improving the overall practicality of the device and reducing environmental interference when not in use.

[0035] Embodiment: When the overall length of the adjustment component 8 cannot meet the height requirement, the adjustment rod 803 can be pressed upward to make the adjustment rod 803 move upward relative to the movable inner tube 802. At this time, the adjustment rod 803 can drive the limit plate 806 and the mounting plate 808 to move upward. At this time, the limit spring 807 is compressed. At the same time, when the mounting plate 808 moves upward, it can drive the multiple support rods 8012 to deflect toward the middle and apply tension to the multiple fourth fixing seats 8011. At this time, the multiple fourth fixing seats 8011 are relatively close to each other, and drive the supporting rubber block 8013 to be relatively close to release the release between it and the inner wall of the fixed tube 801.

10. The method for adjusting the retractable and adjustable medical annular pendant according to claim 9, characterized in that: The following steps are involved: S1: When the horizontal position of the device needs to be adjusted, the operating rod (601) can be directly pushed upwards, and the movable seat (602) and the first fixed seat (603) rise accordingly, and drive the multiple connecting rods (605) to deflect toward the outer side surface, so that a thrust can be applied to the guide block (7), so that the multiple guide blocks (7) are displaced toward the outer side surface; S2: At this time, the plurality of adjustment components (8) and the storage enclosure (9) can be expanded outward at the same time, changing the horizontal position of the adjustment component (8) for installing different accessories. Conversely, the operating rod (601) can be pulled downward, and the plurality of connecting rods (605) can be retracted inward at the same time, so that the plurality of adjustment components (8) can be driven to move closer to the middle, and the plurality of storage enclosures (9) can be relatively close to each other until they form a cylindrical shape, thereby completing the adjustment process; S3: When the length of the adjustment assembly (8) needs to be adjusted, the adjustment rod (803) can be pressed upwards and the movable inner tube (802) can be pulled downwards. When the adjustment rod (803) moves upwards relative to the movable inner tube (802), the mounting plate (808) moves upwards accordingly, which can drive the plurality of support rods (8012) to deflect toward the middle, and finally drive the plurality of support rubber blocks (8013) to retract simultaneously, thereby releasing the contact with the inner wall of the fixed tube (801). At this time, the limit of the movable inner tube (802) is released, and the movable inner tube (802) can be pulled downwards. S4: When the adjustment is to a suitable position, the pressure on the adjustment rod (803) can be released, and the limit spring (807) is reset accordingly, which can drive the mounting plate (808) to automatically reset, and can drive the supporting rubber block (8013) to automatically reset and contact with the fixing tube (801), thereby completing the limit with the fixing tube (801) and completing the adjustment process.
