Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below by combining the specific drawings.
Referring to fig. 1-3, the corner self-locking mechanism provided in this example mainly comprises a locking knob 1, a drum shaft 2, a damping shaft sleeve 3, a drum wheel seat 4, a corner knob 5, a damping switch shaft 6, an adjusting screw 7, a damping cam disc 8, a damping sheet 9, an adjusting block 10, a transmission cam disc 11, a rotation stopping check ring 12, a drum wheel fixing screw 13 and a drum wheel 14.
The angled self-locking mechanism consisting of the above-mentioned components is integrally housed in a housing 15, which housing 15 preferably has a cylindrical housing cavity.
The locking knob 1 in the corner self-locking mechanism is used as a locking adjusting part for an operator to use and adopts a design conforming to human engineering. The specific structure may be determined according to actual requirements, and will not be described herein.
The drum wheel seat 4 of the corner self-locking mechanism is arranged in the shell 15 and serves as a seat for arranging other components.
The drum wheel shaft 2, the damping shaft sleeve 3, the drum wheel seat 4, the damping cam disc 8, the damping sheet 9, the adjusting block 10, the transmission cam disc 11, the rotation stopping check ring 12 and the drum wheel 14 in the bend angle self-locking mechanism are matched to form a corresponding damping adjusting locking mechanism, are arranged on the drum wheel seat 4, are connected and matched with the locking knob 1 through the damping switch shaft 6 and are also matched and connected with the bend angle knob 5.
Thus, the damping switch shaft 6 may be driven to rotate within the drum housing 4 by the locking knob 1, e.g., the damping switch shaft 16 may be driven to rotate in a first direction (e.g., clockwise with respect to the housing 15) to drive the damping adjustment locking mechanism to generate frictional damping to lock the corner knob 5; for example, to actuate the damper switch shaft 6 when rotated in a second direction (e.g., counterclockwise relative to the housing 15), the damper adjustment lockout mechanism will be actuated to remove frictional damping to release the corner knob 5.
Specifically, in this embodiment, when the damping adjustment locking mechanism is formed, the damping shaft sleeve 3 and the drum wheel seat 4 are in interference fit to form a whole, and the damping switch shaft 6 passes through the damping shaft sleeve 3 on the drum wheel seat 4 to be connected with the locking knob 1 and can be driven by the locking knob 1 to rotate in the damping shaft sleeve 3.
An adjusting block 10, a transmission cam plate 11, a damping cam plate 8, a damping sheet 9 and a drum 14 are sequentially superposed on the inner end surface (namely the end surface opposite to the locking knob 1) of the drum seat 4.
The adjusting block 10 is fixedly connected with the drum wheel seat 4 through an adjusting screw 7, and the distance of the adjusting block 10 relative to the drum wheel seat 4 can be controlled through the control of the adjusting screw 7, so that the friction force in the damping adjusting and locking mechanism can be adjusted.
And the drum shaft 2 sequentially passes through the drum seat 4, the adjusting block 10, the transmission cam plate 11, the damping cam plate 8 and the damping sheet 9 to reach the drum wheel 14, the tail end of the drum shaft 2 is fixed with the drum wheel 14 through a fixing screw 13, and the top end of the drum shaft 2 is connected with the corner knob 5. Therefore, the drum shaft 2 is matched with the drum wheel 14 and the corner knob 5, the transmission cam disc 11, the damping cam disc 8 and the damping sheet 9 are sequentially arranged in an overlapping mode, meanwhile, the transmission cam disc 11 can rotate around the drum shaft 2, and the damping cam disc 8 and the damping sheet 9 can move axially along the drum shaft 2; and the corner knob 5 is linked with the drum 14 through the drum shaft 2.
The transmission cam plate 11 which is arranged in an overlapping mode is in transmission fit with the damping switch shaft 6 and can rotate around the drum shaft 2 under the driving of the damping switch shaft 6.
Preferably, a gear transmission is used as the transmission between the transmission cam disk 11 and the damping switch shaft 6, i.e. gears are provided on the damping switch shaft 6 and the transmission cam disk 11 which mesh with each other, so that a rotation of the damping switch shaft 6 drives the transmission cam disk 11 to rotate about the drum shaft 2.
Alternatively, the transmission mechanism between the transmission cam plate 11 and the damping switch shaft 6 may be a transmission mechanism formed by a sliding chute and a sliding block matched with a connecting rod or a transmission mechanism formed by a worm gear and worm, and is not limited herein.
The damping cam disc 8 in this mechanism is provided with a rotation stop mechanism, preferably a rotation stop rib. For the damping cam disc 8 with the structure, a rotation stopping check ring 12 in the mechanism is fixedly arranged on the drum wheel seat 4 through a screw, and a corresponding rotation stopping groove is arranged on the rotation stopping check ring 12, and the rotation stopping groove is just matched with a rotation stopping convex rib on the damping cam disc 8 when the rotation stopping check ring 12 is fixed on the drum wheel seat 4 so as to limit the rotation of the damping cam disc 8, so that the damping cam disc 8 can only move along the axial direction.
Further, the opposite surfaces of the transmission cam plate 11 and the damping cam plate 8 in the mechanism are respectively and correspondingly provided with a matched distance adjusting driving block. Based on the distance adjusting driving block, the transmission cam plate 11 is driven by the damping switch shaft 6 to rotate relative to the damping cam plate 8, the damping cam plate 8 can be driven to move axially through the matching of the distance adjusting driving block and the damping cam plate 8 (the damping cam plate 8 can only move axially limited by the rotation stopping check ring 12), and meanwhile, the damping cam plate 8 moving axially drives the damping plates 9 to move axially towards the drum 14 until the damping cam plate 8 contacts the end face of the drum 14.
Preferably, the distance adjustment drive block provided on the transmission cam plate 11 and the damping cam plate 8 in the present mechanism is preferably a slide-shaped distance adjustment drive block, thereby achieving linear adjustment of the distance between the transmission cam plate 11 and the damping cam plate 8.
Taking the scheme of the pitch adjustment drive block provided in the transmission cam plate 11 as an example, as shown in fig. 2 and 3, the slide-shaped pitch adjustment drive block 11-1 is formed in a circular arc shape as a whole, and has a top surface which is a slope smoothly inclined from one end to the other end and serves as a drive surface.
Thus, a plurality of the above-structured slide-shaped pitch adjustment drive blocks 11-1 are provided on the end surface of the transmission cam plate 11 facing the damping cam plate 8. The specific number may be determined according to actual requirements, such as three in the scheme of the figure, but is not limited thereto.
The slide-shaped spacing adjustment driving blocks 11-1 may or may not be distributed along the same circumference (for example, distributed along a plurality of concentric circumferences), may or may not be distributed equidistantly.
At the same time, the damping cam disk 8 is also provided with corresponding slide-shaped distance adjustment drive blocks 11-1 on the end surface facing the transmission cam disk 11, the number and the position of the slide-shaped distance adjustment drive blocks are the same as the arrangement scheme on the transmission cam disk 11, but the arrangement direction of each slide-shaped distance adjustment drive block 11-1 is opposite (namely the inclination direction of the top surface is opposite).
When the transmission cam plate 11 and the damping cam plate 8 are arranged in this way, the transmission cam plate 11 is driven by the damping switch shaft 6 to rotate along a first direction (such as a counterclockwise direction) relative to the damping cam plate 8, and the slide-shaped spacing adjustment driving block on the transmission cam plate 11 and the slide-shaped spacing adjustment driving block on the damping cam plate 8 gradually rotate from the lowest point to the highest point in a staggered manner from the lowest point to the highest point, so that the distance between the transmission cam plate 11 and the damping cam plate 8 is increased (as shown in fig. 4), in the process, the damping cam plate 8 does not rotate after being matched with the rotation stopping groove on the rotation stopping check ring 12 by virtue of the rotation stopping convex rib, and can only do linear motion along the axial direction; while the damping cam plate 8 moves linearly, the damping cam plate 9 is pushed to contact the end face of the drum 14, and friction damping is generated at the moment to lock the drum 14, so that the drum cannot rotate relative to the damping cam plate 9, and then the corner knob is locked. In this process, the friction damping will be gradually increased in a linear fashion based on the interaction of the slide-shaped spacing adjustment drive blocks until the corner knob is locked.
On the contrary, when the transmission cam plate 11 is driven by the damping switch shaft 6 to rotate in a second direction (e.g. clockwise direction) relative to the damping cam plate 8, the slide-type spacing adjustment driving block on the transmission cam plate 11 and the slide-type spacing adjustment driving block on the damping cam plate 8 are gradually dislocated and rotated from the superposed highest point to the lowest point, at this time, the transmission cam plate 11 will no longer form axial thrust on the damping cam plate 8, and then the damping plate 9 will no longer press against the end surface of the drum 14, the frictional damping between the damping plate 9 and the end surface of the drum 14 disappears, and the drum 14 can rotate relative to the damping plate 9, thereby realizing the release of the bend angle knob.
When the bending angle self-locking mechanism formed based on the scheme is used in cooperation with an endoscope, when a doctor operates the endoscope to take a biopsy on a lesion, the damping switch shaft 6 can be rotated clockwise, gear teeth on the damping switch shaft 6 drive the transmission cam disc 11 to rotate anticlockwise, the slide features on the transmission cam disc 11 and the slide features on the damping cam disc 8 gradually rotate from the lowest point to the highest point in a staggered manner, in the process, the damping cam disc 8 does not rotate after being matched with the rotation stopping groove on the rotation stopping check ring 12 through the rotation stopping convex rib, only axial linear motion is generated, the damping cam disc 8 linearly moves to push the damping sheet 9 to contact the end face of the drum wheel 14, at the moment, friction force is generated, and the bending angle operation knob self-locking function is started.
Meanwhile, the self-locking function of the bend angle operation knob can be closed through reverse operation.
When the friction force is insufficient due to machining errors of the sizes of parts in the using process, the adjusting block 10 can be pushed up by rotating the adjusting screw 7, the transmission cam disc is pushed up by the lifted adjusting block, the damping cam disc is pushed up by the transmission cam disc, the damping cam disc pushes up the damping sheet, and the friction force between the damping sheet and the end face of the drum wheel is increased, so that the effect of adjusting the friction force is achieved.
Finally, it should be noted that the first direction, the second direction, the clockwise direction, and the counterclockwise direction referred to in this example are used to illustrate the operation of the present solution, and do not limit the configuration of the present solution.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
