Abstract
Description
Technical Field
[0001] This utility model relates to the field of hovering arm technology, and in particular to a hovering arm mechanism. Background Technology
[0002] In fields such as medical care, industrial inspection, and film and television shooting, it is often necessary to flexibly suspend and reliably fix external equipment (such as monitors, sensors, lighting devices, medical equipment, etc.) at any position in three-dimensional space. Traditional outrigger mechanisms mostly use mechanical locking or hydraulic damping structures to achieve posture fixation, but there are significant shortcomings: most medical outriggers on the market with locking have a knob for each of the three joints, and it is extremely cumbersome for medical personnel to fix the knob with one hand, which makes it easy for connected medical equipment to fall and may cause other accidents.
[0003] In response to the problems existing in the outrigger, our company has proposed a device that can keep the equipment in a suspended state without human operation. It can be fully unlocked by operating a single switch, allowing the device to be pushed to any position and angle with resistance to prevent it from falling. Releasing the switch locks the device, greatly facilitating the operation of medical personnel. Summary of the Invention
[0004] This utility model addresses the problems of existing technologies by providing a hovering outrigger mechanism. A resistance adjustment component is used to adjust the resistance between the universal joint connector and the first outrigger, accommodating external equipment of varying weights. The mechanism is easy to adjust and flexible to use. The rotating base can rotate 360° relative to the support base, allowing for orientation adjustment of the outrigger body. The mechanism ensures the equipment remains hovered even when unattended. A single control button fully unlocks the outrigger body, allowing external equipment to be pushed to any position and angle with resistance to prevent falling. Releasing the control button locks the outrigger body, greatly facilitating operator use.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] This utility model provides a suspended outrigger mechanism, which includes a support base and an outrigger body. A rotating base is rotatably mounted on the support base. The outrigger body includes a control component, a first outrigger, and a second outrigger. One end of the first outrigger is movably equipped with a universal joint connector and a resistance adjustment component for adjusting the resistance of the universal joint connector. The other end of the first outrigger is rotatably connected to one end of the second outrigger, and the other end of the second outrigger is movably connected to the rotating base. The control component includes a control button, a first control switch, and a second control switch. A first locking component is installed inside the first outrigger, and a second locking component is installed inside the second outrigger. The first control switch is connected to the first locking component, and the second control switch is connected to the second locking component. The control button is used to simultaneously pull the first control switch and the second control switch to unlock the first locking component and the second locking component respectively, so that the outrigger body can move relatively. When the control button does not pull the first control switch and the second control switch, the outrigger body is locked.
[0007] The first support arm has a movable ball cavity at one end, and one end of the universal joint connector is movably disposed within the movable ball cavity. The resistance adjustment assembly includes a connecting bracket, an elastic element, a top block, a pressure block, a resistance adjustment screw, a transmission bevel gear, a drive bevel gear, and a resistance adjustment component. The connecting bracket is installed inside the first support arm, and the resistance adjustment component is rotatably disposed on the first support arm and the connecting bracket. One end of the resistance adjustment component protrudes into the first support arm and is fixedly fitted with the drive bevel gear. One end of the top block extends into the movable ball cavity and abuts against the universal joint connector. One end of the force adjusting screw slides through the other end of the top block, and the other end of the resistance adjusting screw is rotatably connected to the connecting bracket. The transmission bevel gear is fixedly sleeved on the other end of the resistance adjusting screw, and the transmission bevel gear meshes with the drive bevel gear for transmission. The elastic element is movably sleeved on the outer circumference of the resistance adjusting screw, and the pressure block is threadedly sleeved on the outer circumference of the resistance adjusting screw. The elastic element is located between the pressure block and the top block, and both ends of the elastic element are respectively connected to the pressure block and the top block. The pressure block and the top block respectively slide against the inner wall of the first support arm.
[0008] The elastic element is a spring.
[0009] The resistance adjustment component is a bolt or a pin.
[0010] The supporting base has a positioning shaft column in the middle, and the lower end of the rotating base has a positioning shaft groove that cooperates with the positioning shaft column. The positioning shaft column is movably disposed in the positioning shaft groove, and a bushing is sleeved on the outer periphery of the positioning shaft column. The bushing abuts against the inner wall of the positioning shaft groove.
[0011] The positioning shaft column is provided with a connecting groove, and a connecting screw is installed in the connecting groove. A connecting screw hole is opened at the upper end of the inner wall of the positioning shaft groove. The upper end of the connecting screw passes through the connecting groove and is screwed into the connecting screw hole.
[0012] The rotating base has an adjustment gap on one side and two connecting ears on the other side. The two connecting ears are spaced apart and are located on both sides of the adjustment gap. One of the connecting ears is equipped with an adjustment screw, which passes through one of the connecting ears and is threaded to the other connecting ear.
[0013] The second support arm has a rotating seat at one end, and a first connecting shaft and a second connecting shaft are respectively provided at the lower and upper ends of the rotating seat. One end of the first locking component is movably connected to one end of the inner wall of the first support arm, and the other end of the first locking component is connected to a first movable block, which is movably connected to the first connecting shaft. One end of the second locking component is connected to a second movable block, which is movably connected to the second connecting shaft, and the other end of the second locking component is movably connected to the rotating base.
[0014] Both the first locking component and the second locking component are gas springs.
[0015] The first control switch is connected to a first pull rope, and the second control switch is connected to a second pull rope. The first pull rope and the second pull rope are respectively connected to the control button. When the control button is pressed, the first control switch and the second control switch are pulled by the first pull rope and the second pull rope respectively, so that the first locking component and the second locking component are unlocked.
[0016] The beneficial effects of this utility model are:
[0017] In this invention, the universal joint connector is used to connect with external equipment. The universal joint connector is movably disposed at one end of the first support arm, and the resistance adjustment component is used to adjust the resistance between the universal joint connector and the first support arm to accommodate external equipment of different weights. It is easy to adjust and flexible to use. The rotating base can rotate 360° relative to the support base to adjust the orientation of the support arm body.
[0018] Furthermore, the first and second arms of the outrigger body can rotate relative to each other, and the second arm can rotate relative to the rotating base. When the operator presses the control button, the first and second pull ropes are pulled simultaneously, causing the first and second control switches to open, thereby unlocking the first and second locking components respectively, so that the outrigger body can move relative to each other, that is, the first arm can rotate relative to the second arm, and the second arm can rotate relative to the rotating base.
[0019] When the operator does not press the control button, and the control button does not pull the first and second pull ropes, that is, when the first and second control switches are not turned on, the first and second control switches are in the closed state, so that the main body of the support arm is locked, the first and second support arms are relatively locked and cannot rotate, and the second support arm and the rotating base are relatively locked and cannot rotate.
[0020] With the above settings, pressing the control button turns on the first and second control switches, which unlocks the gas spring lock, allowing the two joints of the first and second arms to rotate freely. The gas spring itself provides resistance, further ensuring the safety of the connected external equipment. This resistance counteracts the weight of the equipment, allowing operators to easily move and secure various external devices. During use, the movement is smooth and easy, meeting the needs of supporting equipment to reach any fixed position. The support base is screwed onto a medical cart or other suitable bracket for fixation. The external equipment is connected and fixed to the universal joint connector. After pressing and holding the control button, pulling the external equipment to the desired position and angle and then releasing the control button completes the suspension and fixation of the external equipment. The structure is novel and easy to use.
[0021] This invention ensures the equipment remains suspended even when no one is operating it. The main body of the outrigger can be fully unlocked by operating only one control button, allowing external equipment to be pushed to any position and angle with resistance to prevent it from falling. Releasing the control button locks the main body of the outrigger, greatly facilitating the use by operators. Attached Figure Description

[0030] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.
[0031] A type of hovering boom mechanism, such as Figures 1 to 4As shown, it includes a support base 100 and a support arm body 200. A rotating base 300 is rotatably mounted on the support base 100. The support arm body 200 includes a control component, a first support arm 1, and a second support arm 2. One end of the first support arm 1 is movably mounted with a universal joint connector 400 and a resistance adjustment component 500 for adjusting the resistance of the universal joint connector 400. The other end of the first support arm 1 is rotatably connected to one end of the second support arm 2, and the other end of the second support arm 2 is movably connected to the rotating base 300. The control component includes a control button 3, a first control switch 4, and a second control switch 5. The control switch 5 is provided. The first support arm 1 is equipped with a first locking component 6, and the second support arm 2 is equipped with a second locking component 7. The first control switch 4 is connected to the first locking component 6, and the second control switch 5 is connected to the second locking component 7. The control button 3 is used to simultaneously pull the first control switch 4 and the second control switch 5 to unlock the first locking component 6 and the second locking component 7 respectively, so that the support arm body 200 can move relative to each other. When the control button 3 does not pull the first control switch 4 and the second control switch 5, the support arm body 200 is locked.
[0032] The second support arm 2 has a rotating seat 8 at one end. The lower and upper ends of the rotating seat 8 are respectively provided with a first connecting shaft 9 and a second connecting shaft 10. One end of the first locking component 6 is movably connected to one end of the inner wall of the first support arm 1, and the other end of the first locking component 6 is connected to a first movable block 11, which is movably connected to the first connecting shaft 9. One end of the second locking component 7 is connected to a second movable block 12, which is movably connected to the second connecting shaft 10. The other end of the second locking component 7 is movably connected to the rotating base 300. Both the first locking component 6 and the second locking component 7 are gas springs. A first pull rope 13 is connected to the first control switch 4, and a second pull rope 14 is connected to the second control switch 5. The first pull rope 13 and the second pull rope 14 are respectively connected to the control button 3. When the control button 3 is pressed, the first control switch 4 and the second control switch 5 are pulled by the first pull rope 13 and the second pull rope 14, respectively, to unlock the first locking component 6 and the second locking component 7.
[0033] Specifically, in this embodiment, the universal joint connector 400 is used to connect with external devices. The universal joint connector 400 is movably disposed at one end of the first support arm 1, and the resistance adjustment component 500 is used to adjust the resistance between the universal joint connector 400 and the first support arm 1, so as to adapt to external devices of different weights. It is convenient to adjust and flexible to use. The rotating base 300 can rotate 360° relative to the support base 100 to adjust the orientation of the support arm body 200.
[0034] Furthermore, the first arm 1 and the second arm 2 of the support arm body 200 can rotate relative to each other, and the second arm 2 can rotate relative to the rotating base 300. When the operator presses the control button 3, the first pull rope 13 and the second pull rope 14 are pulled at the same time, so that the first control switch 4 and the second control switch 5 are opened, and the first locking component 6 and the second locking component 7 are unlocked respectively, so that the support arm body 200 can move relative to each other, that is, the first arm 1 can rotate relative to the second arm 2, and the second arm 2 can rotate relative to the rotating base 300.
[0035] When the operator does not press the control button 3, and the control button 3 does not pull the first pull rope 13 and the second pull rope 14, that is, when the first control switch 4 and the second control switch 5 are not opened, the first control switch 4 and the second control switch 5 are in the closed state, so that the support arm body 200 is locked, the first support arm 1 and the second support arm 2 are relatively locked and cannot rotate, and the second support arm 2 and the rotating base 300 are relatively locked and cannot rotate.
[0036] With the above settings, pressing control button 3 opens the first control switch 4 and the second control switch 5, thus unlocking the gas spring lock. The two joints of the first arm 1 and the second arm 2 can rotate freely. The gas spring itself has force resistance, further ensuring the safety of the connected external equipment. The resistance offsets the weight of the equipment, allowing operators to easily move and fix various external equipment. During use, the movement is easy and smooth, meeting the needs of supporting equipment to reach any fixed position for operation. The support base 100 is screwed onto a medical cart or other bracket that can be used for fixation. The external equipment is connected and fixed to the universal connector 400. After pressing and holding control button 3, pulling the external equipment to the required position and angle and then releasing control button 3 completes the suspension and fixation of the external equipment. The structure is novel and easy to use.
[0037] In this embodiment, the universal joint connector 400 includes a universal ball joint 15 and a threaded connection portion 16 disposed at one end of the universal ball joint 15. The threaded connection portion 16 is used to connect with external equipment. A movable ball cavity 17 is provided at one end of the first support arm 1, and one end of the universal joint connector 400 is movably disposed within the movable ball cavity 17, i.e., the universal ball joint 15 is movably disposed within the movable ball cavity 17. The resistance adjustment assembly 500 includes a connecting bracket 18, an elastic element 19, a top block 20, a pressure block 21, a resistance adjustment screw 22, a transmission bevel gear 23, a drive bevel gear 24, and a resistance adjustment component 25. The connecting bracket 18 is installed inside the first support arm 1, and the resistance adjustment component 25 is rotatably disposed on the first support arm 1 and the connecting bracket 18. One end of the resistance adjustment component 25 protrudes into the first support arm 1 and is fixedly sleeved thereon. The drive bevel gear 24, one end of the top block 20 extends into the movable ball cavity 17 and abuts against the universal joint connector 400, one end of the resistance adjusting screw 22 slides through the other end of the top block 20, and the other end of the resistance adjusting screw 22 is rotatably connected to the connecting bracket 18, the transmission bevel gear 23 is fixedly sleeved on the other end of the resistance adjusting screw 22, and the transmission bevel gear 23 meshes with the drive bevel gear 24 for transmission, the elastic element 19 is movably sleeved on the outer periphery of the resistance adjusting screw 22, the pressure block 21 is threaded on the outer periphery of the resistance adjusting screw 22, the elastic element 19 is located between the pressure block 21 and the top block 20, and both ends of the elastic element 19 are respectively connected to the pressure block 21 and the top block 20, and the pressure block 21 and the top block 20 respectively slide against the inner wall of the first support arm 1. The elastic element 19 is a spring. The resistance adjusting element 25 is a bolt or a pin.
[0038] Specifically, under the above configuration, rotating the resistance adjusting component 25 drives the drive bevel gear 24 to rotate, which in turn drives the transmission bevel gear 23 to rotate, which in turn drives the resistance adjusting screw 22 to rotate, thereby driving the pressure block 21 to move back and forth along the resistance adjusting screw 22. When the pressure block 21 moves forward toward the universal joint connector 400, the elastic component 19 pushes the top block 20 forward to increase the frictional resistance between the top block 20 and the universal joint connector 400. When the resistance adjusting component 25 is rotated in the opposite direction, the pressure block 21 is moved away from the universal joint connector 400 to reduce the frictional resistance between the top block 20 and the universal joint connector 400. Under the above configuration, the frictional resistance is adjustable, adaptable to external equipment of various weights, and can meet various angle requirements when the external equipment is working.
[0039] This application is mainly used to fix and support various medical devices, providing secure and flexible adjustment functions to ensure that doctors or nurses can easily adjust the position and angle of external devices during operation.
[0040] In this embodiment, a positioning shaft post 26 is provided in the middle of the support base 100, and a positioning shaft groove 27 that mates with the positioning shaft post 26 is provided at the lower end of the rotating base 300. The positioning shaft post 26 is movably disposed within the positioning shaft groove 27, and a bushing 28 is fitted around the outer periphery of the positioning shaft post 26. The bushing 28 abuts against the inner wall of the positioning shaft groove 27. A connecting groove 29 is provided through the positioning shaft post 26, and a connecting screw 30 is installed within the connecting groove 29. A connecting screw hole is provided at the upper end of the inner wall of the positioning shaft groove 27, and the upper end of the connecting screw 30 passes through the connecting groove 29 and is screwed into the connecting screw hole. Specifically, with the cooperation of the positioning shaft column 26 and the positioning shaft groove 27, the rotating base 300 is positioned on the support base 100. Furthermore, with the above configuration, the bushing 28 can reduce the wear between the rotating base 300 and the support base 100. The bushing 28 plays a protective and anti-slip role, and with the action of the connecting screw 30, it prevents the rotating base 300 from detaching from the support base 100.
[0041] Furthermore, an adjustment gap 32 is provided on one side of the rotating base 300, and two connecting ears 33 are also provided on one side of the rotating base 300. The two connecting ears 33 are spaced apart and are located on both sides of the adjustment gap 32. An adjusting screw 31 is installed on one of the connecting ears 33. The adjusting screw 31 passes through one of the connecting ears 33 and is threadedly connected to the other connecting ear 33. Specifically, with the above configuration, turning the adjusting screw 31 can adjust the distance between the two connecting ears 33, thereby adjusting the distance of the adjustment gap 32. This allows the rotating base 300 to better clamp the positioning shaft 26, increasing the clamping force. In other words, the clamping force between the rotating base 300 and the positioning shaft 26 is adjustable, preventing loosening.
[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
