Description

Technical Field

[0001] The present invention relates to the technical field of hovering arms, and in particular to a one-button controlled hovering arm device. Background Art

[0002] In the fields of medical treatment, industrial testing, film and television shooting, etc., it is often necessary to flexibly hover external equipment (such as displays, sensors, lighting devices, medical equipment, etc.) at any position in three-dimensional space and reliably fix them. Traditional arm mechanisms mostly use mechanical locking or hydraulic damping structures to achieve posture fixation, but there are significant shortcomings: most of the locked medical arms on the market have a knob corresponding to the three joints. It is extremely cumbersome for medical staff to fix the knob with one hand, which makes the connected medical equipment easy to fall and may cause other accidents.

[0003] In response to the problems existing in the existing support arms, our company has proposed a method to ensure that the equipment is in a hovering state when no one is operating it. It can be completely unlocked by simply operating a switch, ensuring that the equipment can be pushed to any position and angle with resistance to prevent it from falling. It will be locked when the switch is released, which greatly facilitates the operation of medical staff. Summary of the Invention

[0004] In response to the problems of the prior art, the present invention provides a one-button controlled hovering arm device, which is used to adjust the resistance of the connection between the universal head connector and the first arm through a resistance adjustment component, so as to adapt to external devices of different weights. The adjustment is convenient and the use is flexible. The rotating base can rotate 360° relative to the support base to adjust the orientation of the arm body. The device can be kept in a hovering state without anyone operating it. The arm body can be completely unlocked by operating only one control button, ensuring that the external device can be pushed to any position and angle with resistance to prevent it from falling. Releasing the control button will lock the arm body, which greatly facilitates the use of the operator.

When the control button 3 is pressed, the first and second control switches 4 and 5 are pulled by the first and second pull cords 13 and 14, respectively, to unlock the first and second locking members 6 and 7.

[0033] Specifically, in the embodiment of the present application, the universal head connector 400 is used to connect to an external device. The universal head connector 400 is movably disposed at one end of the first arm 1, and the resistance adjustment assembly 500 is used to adjust the resistance of the connection between the universal head connector 400 and the first arm 1, so as to adapt to external devices of different weights, with convenient adjustment and flexible use.

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 turned on, the first control switch 4 and the second control switch 5 are in the closed state, so that the arm body 200 is locked, the first arm 1 and the second arm 2 are relatively locked and cannot rotate, and the second arm 2 and the rotating base 300 are relatively locked and cannot rotate;

[0036] Under the above settings, after pressing the control button 3 and turning on the first control switch 4 and the second control switch 5, the gas spring lock of the gas spring is opened, and the two joints of the first arm 1 and the second arm 2 can be rotated at will; and the gas spring itself has a force resistance, which further ensures the safety of the connected external equipment. The resistance offsets the weight of the equipment, allowing the operator to easily move and fix various external equipment; when in use, the movement is easy and smooth, meeting the needs of the supported equipment to reach any position and any fixed position for operation. The support base 100 is screwed to the medical cart or other bracket that can be used for fixation, and the external equipment is connected and fixed to the universal head connector 400. After pressing the control button 3, pull the external equipment to the required position and angle, and then release the control button 3 to complete the hovering fixation of the external equipment. The structure is novel and easy to use.

[0037] In the embodiment of the present application, the universal head connector 400 includes a universal ball head 15 and a threaded connection portion 16 arranged at one end of the universal ball head 15, and the threaded connection portion 16 is used to connect to an external device; wherein, a movable ball cavity 17 is opened at one end of the first arm 1, and one end of the universal head connector 400 is movably arranged in the movable ball cavity 17, that is, the universal ball head 15 is movably arranged in the movable ball cavity 17, and the resistance adjustment assembly 500 includes a connecting bracket 18, an elastic member 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 member 25, the connecting bracket 18 is installed in the first arm 1, and the resistance adjustment member 25 is rotatably arranged on the first arm 1 and the connecting bracket 18, and one end of the resistance adjustment member 25 protrudes into the first arm 1 and is fixedly sleeved The driving bevel gear 24 and one end of the top block 20 extend into the movable ball cavity 17 and abut against the universal head connector 400. One end of the resistance adjustment screw 22 slides through the other end of the top block 20, and the other end of the resistance adjustment screw 22 is rotatably connected to the connecting bracket 18. The transmission bevel gear 23 is fixedly mounted on the other end of the resistance adjustment screw 22, and the transmission bevel gear 23 is meshed and transmission-connected with the driving bevel gear 24. The elastic member 19 is movably mounted on the outer periphery of the resistance adjustment screw 22, and the pressure block 21 is threadedly mounted on the outer periphery of the resistance adjustment screw 22. The elastic member 19 is located between the pressure block 21 and the top block 20, with its two ends respectively connected to the pressure block 21 and the top block 20. The pressure block 21 and the top block 20 respectively slide against the inner wall of the first support arm 1. The elastic member 19 is a spring. The resistance adjustment member 25 is a bolt or a pin.

[0038] Specifically, under the above setting, by rotating the resistance adjusting member 25, the driving bevel gear 24 is driven to rotate, thereby driving the transmission bevel gear 23 to rotate, and then driving the resistance adjusting screw 22 to rotate, so as to drive the pressure block 21 to move forward and backward along the resistance adjusting screw 22. When the pressure block 21 moves forward toward the universal head connector 400, the elastic member 19 pushes the top block 20 forward to strengthen the friction resistance between the top block 20 and the universal head connector 400; when the resistance adjusting member 25 is rotated in the opposite direction, the pressure block 21 is driven away from the universal head connector 400 to reduce the friction resistance between the top block 20 and the universal head connector 400; under the above setting, the friction resistance is adjustable to adapt to external equipment of various weights and can meet various angle requirements when the external equipment is working.

[0039] The embodiments of the present application are mainly used to fix and support various medical devices, provide safety and flexible adjustment functions, and ensure that doctors or nurses can easily adjust the position and angle of external devices during operation.

[0040] In the embodiment of the present application, a positioning shaft column 26 is provided in the middle of the support base 100, and a positioning shaft groove 27 is provided at the lower end of the rotating base 300 to cooperate with the positioning shaft column 26. The positioning shaft column 26 is movably disposed in the positioning shaft groove 27. A shaft sleeve 28 is provided around the outer periphery of the positioning shaft column 26, and the shaft sleeve 28 abuts against the inner wall of the positioning shaft groove 27. A connecting groove 29 is provided through the positioning shaft column 26, and a connecting screw 30 is installed in 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, under the above setting, the sleeve 28 can reduce the wear between the rotating base 300 and the support base 100. The sleeve 28 plays a protective and anti-slip role, and under the action of the connecting screw 30, it prevents the rotating base 300 from separating from the support base 100.

[0041] Furthermore, an adjustment gap 32 is defined on one side of the rotating base 300. Two connecting ears 33 are also provided on one side of the rotating base 300. The two connecting ears 33 are spaced apart and located on either side of the adjustment gap 32. An adjustment screw 31 is mounted on one of the connecting ears 33. The adjustment screw 31 passes through one of the connecting ears 33 and then is threadedly connected to the other connecting ear 33. Specifically, under the above arrangement, turning the adjustment screw 31 adjusts the spacing between the two connecting ears 33, thereby adjusting the spacing of the adjustment gap 32. This allows the rotating base 300 to better clamp the positioning shaft column 26 and increase the clamping force. Specifically, the clamping force between the rotating base 300 and the positioning shaft column 26 is adjustable to prevent loosening.
