[0038] The utility model provides a supporting device 100, which aims to improve the safety of an operating table with tilt adjustment.

[0039] In the embodiment of the present utility model, in combination with reference to Figure 1 , Figure 2 The supporting device 100 includes a machine base 10, a power supporting mechanism 30 and an auxiliary supporting mechanism 20. A tilting frame 40 is provided on the top of the machine base 10. The tilting frame 40 is rotatably mounted on the machine base 10. The power supporting mechanism 30 is rotatably mounted on the machine base 10. One end of the power supporting mechanism 30 away from the machine base 10 is rotatably connected to the tilting frame 40. The auxiliary supporting mechanism 20 is arranged on the same side as the power supporting mechanism 30 and is rotatably connected to the machine base 10 and the tilting frame 40.

[0040] It can be understood that the support device 100 is a part of the operating bed, in which the power support mechanism 30 has its own power and can drive the operating bed to tilt in a certain direction, while the auxiliary support mechanism 20 does not have its own power, but the auxiliary support mechanism 20 is arranged on the same side as the power support mechanism 30, so that the auxiliary support mechanism 20 can follow the power support mechanism 30 to extend and retract, thereby providing additional auxiliary supporting force. When the power support mechanism 30 loses its power for some reason, the auxiliary support mechanism 20 can maintain its supporting force, and the auxiliary support mechanism 20 maintains the stability of the tilt frame 40.

[0041] In some embodiments, the power support mechanism 30 can use a cylinder as the power output. In this way, the power support mechanism 30 is relatively stable when moving with the cylinder as the power. At the same time, the power support mechanism 30 can also use a motor as the power output. In this way, the tilt adjustment of the operating bed can be controlled by the control system, making the tilt of the operating bed more precise.

[0042] In other embodiments, the auxiliary support mechanism 20 can use a gas spring as an auxiliary power. When the operating bed is in a tilted state and the power support mechanism 30 loses its supporting power, the gas spring can temporarily maintain its deformation, thereby temporarily maintaining a relatively stable state of the operating bed.

[0043] Further, see Figure 1 , Figure 2 In one embodiment, the base 10 includes a connecting frame 11 and an outer column 12, the tilting frame 40 is rotatably mounted on the connecting frame 11, the end of the auxiliary support mechanism 20 away from the tilting frame 40 is rotatably connected to the connecting frame 11, the connecting frame 11 is fixed to the top of the outer column 12, and the end of the power support mechanism 30 away from the connecting frame 11 is rotatably mounted on the outer column 12.

[0044] In this arrangement, the base 10 is rotatably connected to the tilting frame 40 via the connecting frame 11, and the auxiliary support mechanism 20 is arranged on the connecting frame 11 and rotatably connected to the tilting frame 40. This can reduce the volume of the auxiliary support mechanism 20 and reduce the space occupied by the auxiliary support mechanism 20, so that the extension and retraction amount of the follower power support mechanism 30 of the auxiliary support mechanism 20 is relatively small, thereby maintaining a more stable state of the operating bed.

[0045] In some embodiments, a through hole may be provided on the connecting frame 11, and the auxiliary support mechanism 20 may be inserted into the through hole and rotatably connected by a latch, thereby reducing the structural setting on the connecting frame 11 and making it smaller in size.

[0046] Further, see Figure 1 , Figure 2 In one embodiment, the connecting frame 11 is rotatably connected to the center of the tilting frame 40, the power support mechanism 30 is rotatably connected to the end of the tilting frame 40, and the auxiliary support mechanism 20 is rotatably connected between the center and the end of the tilting frame 40.

[0047] It can be understood that the connecting frame 11 in this embodiment has two upwardly protruding hinge ears, which are respectively arranged at both ends of the connecting frame 11, and two corresponding hinge ears are also arranged at the center of the tilting frame 40. In this way, the connecting frame 11 and the tilting frame 40 are connected to the corresponding hinge ears of the two through a pin to achieve a rotational connection. In this way, the rotation of the tilting frame 40 is carried out with its center as the center of the circle, and the rotation of the tilting frame 40 is relatively stable.

[0048] In some embodiments, only one hinge ear may be provided at the center of the tilting frame 40. In this case, the spacing between the hinge ears on the connecting frame 11 is equal to the width of the hinge ears on the tilting frame 40. In this way, the hinge ears on the tilting frame 40 can be first clamped on the connecting frame 11 and then connected by a pin.

[0049] Further, see Figures 1 to 3 In one embodiment, the auxiliary support mechanism 20 includes a gas spring 21 and an auxiliary extension rod 22. One end of the gas spring 21 is rotatably installed on the connecting frame 11, and the auxiliary extension rod 22 is movably installed in the gas spring 21. The end of the auxiliary extension rod 22 away from the connecting frame 11 is rotatably connected to the tilting frame 40.

[0050] In this configuration, the auxiliary support mechanism 20 is in the form of a gas spring 21 , and the gas spring 21 can well maintain a relatively stable state of the tilt frame 40 by utilizing the damping characteristics of the gas inside the gas spring 21 .

[0051] In some embodiments, the inside of the gas spring 21 may be filled with an inert gas (nitrogen, helium, etc.), or may be filled with an oil-gas mixture, so that the gas spring 21 can ensure that its movement is softer and smoother.

[0052] Further, see Figure 3 In one embodiment, a circular hole 221 is provided at one end of the auxiliary extension rod 22 away from the connecting frame 11 , and the tilting frame 40 is rotatably connected to the circular hole 221 via a rotating rod 41 .

[0053] In this way, a circular hole 221 is set at one end of the auxiliary extension rod 22 away from the connecting frame 11, and the circular hole 221 is connected to the tilting frame 40 through the rotating rod 41, so that during the tilting process of the tilting frame 40, the circular hole 221 and the auxiliary extension rod 22 rotate relative to each other, and then the auxiliary support device 100 follows the rotation, and the auxiliary support device 100 follows the rotation state, and the state of following the rotation is relatively stable.

[0054] In some embodiments, a clearance fit may be used between the circular hole 221 and the auxiliary extension rod 22 , so that during the relative rotation between the circular hole 221 and the auxiliary extension rod 22 , the friction between the circular hole 221 and the auxiliary extension rod 22 is small, and the tilting frame 40 tilts more smoothly.

[0055] Further, see Figure 1 , Figure 2 In one embodiment, a fixing seat 111 is provided on the connecting frame 11 , and a protrusion 211 is provided at one end of the gas spring 21 away from the tilting frame 40 , and the protrusion 211 is rotatably mounted on the fixing seat 111 .

[0056] With such arrangement, the gas spring 21 rotates the case and the fixing seat 111 via the protrusion 211 , so that when the power support device 100 loses power, the gas spring 21 needs to temporarily bear a relatively large pressure, so that the pressure can be transferred to the connecting frame 11 via the fixing seat 111 .

[0057] In some embodiments, a groove that matches the shape of the protrusion 211 can be set on the fixing seat 111, so that when the gas spring 21 transfers pressure to the connecting frame 11, the contact area between the protrusion 211 and the connecting frame 11 is larger, and the pressure is smaller, thereby improving the structural strength of the connecting frame 11.

[0058] Further, see Figures 1 to 4 In one embodiment, the power support mechanism 30 includes a cylinder 31 and a power extension rod 32, one end of the cylinder 31 is rotatably mounted on the side wall of the outer column 12, the power extension rod 32 is movably mounted on the cylinder 31, and one end of the power extension rod 32 is rotatably connected to one end of the tilt frame 40.

[0059] In this configuration, the power support mechanism 30 uses the oil cylinder 31 as power, and drives the power extension rod 32 to extend or retract through the oil cylinder 31, thereby driving the tilting frame 40 to tilt, so that the driving effect of the power support mechanism 30 is relatively stable.

[0060] In some embodiments, two power support mechanisms 30 may be provided, and the two power support mechanisms 30 are respectively connected to the left-right direction and the front-back direction of the tilt frame 40 , so that the tilt frame 40 can be controlled to tilt in the left-right direction and the front-back direction.

[0061] Further, see Figure 4 In one embodiment, the power support mechanism 30 further includes a sealing ring 33 , which is sleeved on the power extension rod 32 , and the sealing ring 33 seals the gap between the oil cylinder 31 and the power extension rod 32 .

[0062] In this way, a sealing ring 33 is sleeved on the power extension rod 32. When the power extension rod 32 is extended from or retracted into the oil cylinder 31, the sealing ring 33 is always fixed at the opening of the oil cylinder 31, thereby preventing leakage of substances inside the oil cylinder 31 and causing insufficient power of the power support mechanism 30.

[0063] In some embodiments, the material of the sealing ring 33 can be various rubbers, such as nitrile rubber, fluororubber, silicone rubber, etc., so that the sealing ring 33 can have good oil resistance and wear resistance, so that the sealing ring 33 can not only meet the sealing effect, but also make the extension and retraction process of the power extension rod 32 smoother.

[0064] Further, see Figure 1In one embodiment, the supporting device 100 further includes a solenoid valve assembly 50 , which is mounted on a side wall of the base 10 and spaced apart from the power supporting mechanism 30 .

[0065] In this way, the solenoid valve assembly 50 can control the power output of the power support mechanism 30 , and at the same time, the solenoid valve assembly 50 is installed on the side wall of the base 10 , which fully utilizes the installation space of the base 10 .

[0066] In some embodiments, the solenoid valve assembly 50 may be provided with multiple solenoid coils, and the multiple solenoid coils are arranged in parallel, so that the solenoid valve assembly 50 can generate more magnetic force.

[0067] The utility model also proposes an operating bed, which includes a supporting device 100. The specific structure of the supporting device 100 refers to the above embodiment. Since the operating bed adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0068] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
