[0045] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0046] Please refer to the attached Figures 1 to 8, the present utility model provides a lifting mechanism 100, which is applied to an endoscope device. The lifting mechanism 100 includes a bracket 10, a knob 20, a rotating member 30, two lifting columns 40 and a guiding member 50. The knob 20 is located outside the bracket 10, and the rotating member 30, two lifting columns 40 and the guiding member 50 are arranged inside the bracket 10.

[0047] The bracket 10 serves as a supporting component of the lifting mechanism 100, and is used to support the knob 20, the rotating member 30, two lifting columns 40 and the guiding member 50.

[0048] The knob 20 is rotatably connected to the bracket 10; the operating end of the knob 20 is located outside the bracket 10; the driving end of the knob 20 is located inside the bracket 10, so as to facilitate adjusting the position of the knob 20 relative to the bracket 10, thereby facilitating the user to operate outside the bracket 10.

[0049] The rotating member 30 is arranged inside the bracket 10 and is rotatably connected to the bracket 10 respectively, so as to facilitate adjusting the position of the rotating member 30 relative to the bracket 10. The rotating members 30 are respectively located on one side of the driving end of the knob 20 and are connected to the driving end of the knob 20 through a transmission module 21, so that the knob 20 can drive the rotating member 30 to rotate under the operation of the user, thereby facilitating the rotating member 30 to rotate as the knob 20 rotates; the rotating member 30 is provided with a first connecting portion 31.

[0050] Two lifting columns 40 are arranged on both sides of the rotating member 30. The lifting columns 40 are vertically movably connected to the bracket 10, so as to facilitate adjusting the positions of the two lifting columns 40 relative to the bracket 10. The two lifting columns 40 perform reverse lifting as the rotating member 30 rotates; the lifting column 40 is provided with a second connecting portion 41, and the second connecting portion 41 is connected to the first connecting portion 31. The connection structure between the second connecting portion 41 and the first connecting portion 31 is a gear-rack connection structure or a worm-gear connection structure, so that one knob 20 can drive the reverse lifting of the two lifting columns 40, realizing the operation of two lifting columns 40 by one knob 20, avoiding operating the two lifting columns respectively by two knobs, and improving the operation effect of the lifting mechanism 100.

[0051] In the first embodiment, the guiding member 50 is arranged inside the bracket 10. The guiding member 50 is embedded in the bracket 10 and sleeved on part of the lifting column 40, so as to facilitate the guiding member 50 to limit the circumferential position of the lifting column 40, thereby facilitating improving the lifting smoothness of the lifting column 40.

[0052] At this time, the rotating member 30 is further provided with a third connecting portion 32. The third connecting portion 32 and the first connecting portion 31 are arranged side by side along the axial direction of the rotating member 30 and are in different positions, so as to facilitate the staggering arrangement of the driving end of the knob 20 and the lifting column 40. Thus, when the driving end of the knob 20 drives the rotating member 30 to rotate during the rotation process, the lifting column 40 can be lifted and lowered.

[0053] Among them, the transmission module 21 is located between the driving end of the knob 20 and the rotating member 30; the transmission module 21 is a transmission gear, and the transmission gear is sleeved on the driving end of the knob 20, so as to facilitate the fixing of the transmission gear to the driving end of the knob 20. The transmission gear meshes with the third connecting portion 32 of the rotating member 30, so as to facilitate the knob 20 to drive the third connecting portion 32 to rotate through the transmission gear. Thus, it is convenient for the rotating member 30 to rotate as the knob 20 rotates, and further convenient for the first connecting portion 31 and the third connecting portion 32 to rotate simultaneously. Optionally, the outer diameter of the gear of the transmission module 2 is larger than the outer diameter of the rotating member 30.

[0054] In addition, the rotating member 30 is a double-headed gear member, and the rotating member 30 is connected to the bracket 10 through a rotating shaft, so as to facilitate the rotation of the rotating member 30 along the axis direction of the rotating shaft. Thus, it is convenient to realize the rotation of the rotating member 30 relative to the bracket 10, and further convenient to adjust the position of the rotating member 30 relative to the bracket 10.

[0055] In the first embodiment, the connection structure between the second connecting portion 41 and the first connecting portion 31 is a gear-rack connection structure. The second connecting portion 41 is a rack portion, and the first connecting portion 31 is a gear portion; the second connecting portions 41 are arranged in sequence along the axial direction of the lifting column 40 and mesh with the gear portion. The rack portion extends in sequence along the axial direction of the lifting column 40 and is arranged around the circumference of the lifting column 40, so as to facilitate the second connecting portion 41 to lift relative to the first connecting portion 31 through the rack portion and the gear portion. Thus, it is convenient to realize the rotation of the rotating member 30 to drive the lifting column 40 to lift and lower. At the same time, according to the gear-rack connection structure, the space of the bracket 10 is fully utilized, so as to facilitate the spatial design in the up-down and left-right directions, so as to reserve corresponding spaces for the remaining components, thereby optimizing the space occupancy rate of the lifting mechanism.

[0056] In addition, the lifting mechanism further includes a damping flap 60. The damping flap 60 includes a damping main body 61 and a damping flap portion 62. The damping main body 61 is fixed to the bracket, and the damping flap portion 62 is connected to the damping main body 61. The damping flap portion 62 elastically swings relative to the damping main body 61 and elastically presses against the rotating member 30 to apply a damping force to the rotating member 30, so as to perform damping control on the rotating member 30. And a force is applied to the rotating member 30 through the damping flap portion 62, so as to generate a sound. Thus, the number of teeth passed by the rotating member 30 during rotation can be predicted according to the sound, so as to master the control of the rotation angle of the knob 20. At the same time, unnecessary rotation of the rotating member 30 and the knob 20 is prevented, and damping control is realized.

[0057] Optionally, the damping paddle portion 62 is convexly provided with a convex platform, the convex platform is arranged in an arc shape and is located on one side of the first connecting portion 31 to elastically contact the bracket. At the same time, the damping paddle portion 62 is integrally connected to the damping main body 61, and the damping paddle 60 is a paddle with an elastic effect.

[0058] In the first embodiment, the rotating member 30 and the two lifting columns 40 form a set of lifting assemblies. There is at least one set of lifting assemblies, and each set of lifting assemblies is arranged side by side and powered by a corresponding knob 20, so that one knob 20 drives the two lifting columns 40 in a set of corresponding lifting assemblies to lift and lower in the opposite direction, realizing that one knob 20 simultaneously operates the two lifting columns 40 in each set of lifting assemblies, and improving the operation effect of the lifting mechanism 100.

[0059] Among them, the bracket 10 is provided with a positioning hole 10a, and the guiding member 50 is located in the positioning hole 10a and is positioned and connected to the positioning hole 10a, so that the guiding member 50 can be positioned and connected to the bracket 10 through the positioning hole 10a, thereby facilitating the guarantee of the position accuracy of the guiding member 50 relative to the bracket 10, and further facilitating the guarantee of the lifting effect of the lifting column 40 relative to the bracket 10.

[0060] In addition, the guiding member 50 is a copper bushing or a linear bearing, which is not limited here; the lifting column 40 passes through the inner hole of the guiding member 50 in the up and down direction and is guided by the guiding member 50, so that the lifting column 40 can be lifted and lowered under the guiding action of the guiding member 50, thereby facilitating the improvement of the lifting smoothness of the lifting column 40 and guaranteeing the lifting effect of the lifting column 40.

[0061] In the second embodiment, the connection structure between the second connecting portion 41 and the first connecting portion 31 is a worm and worm gear connection structure. The second connecting portion 41 is a worm portion, and the first connecting portion 31 is a worm gear portion; the second connecting portion 41 is arranged in sequence along the axial direction of the lifting column 40 and meshes with the worm gear portion, so that the second connecting portion 41 can be lifted and lowered relative to the first connecting portion 31 through the worm portion and the worm gear portion, thereby facilitating the realization of the rotating member 30 driving the lifting column 40 to lift and lower.
