Fig. 5 shows a block diagram of the drive element 510 as a component of the brake disc drive assembly 500. The specific structure of the driving member 510 is described in detail below with reference to fig. 5, and reference may also be made to fig. 1.
As shown in fig. 5, the driving member 510 includes: a drive member peripheral land 511; a driver hollow bore 513; a driver body 515; a cantilever 517; a cantilevered post 519.
The driving member body 515 is a hollow tube and is located at the lower end of the driving member 510, a driving member hollow hole 513 is formed in the driving member body 515, and the driving member body 515 is sleeved on the outer diameter surface of the second rotating shaft 133 through the driving member hollow hole 513; the driving member body 515 is provided with symmetrical driving member peripheral platforms 511 on an outer circumferential surface thereof, and is fixed to the lower end of the shift lever 530 through the driving member peripheral platforms 511. By pulling the lever 530, the driving member 510 can be driven to rotate. A cantilever 517 is fixed to the front end (left side in fig. 5) of the driving member body 515 in the vertical direction, and a cantilever column 519 is fixed to the upper front end (upper left side in fig. 5) of the cantilever 517. The hanging wall column 519 is inserted into the long hole 350 of the brake disc 300, and the driving member 510 is driven to rotate by driving the shift lever 530 to swing, so as to drive the hanging wall column 519 to slide in the long hole 350.
When the endoscope works, the driving piece 510 is driven to synchronously rotate by pulling the pulling rod 530, the hanging wall column 519 on the driving piece 510 further realizes sliding in the long hole 350, the brake disc 300 swings around the positioning hole 370 under the driving of the hanging wall column 519, so that the brake disc 300 is contacted and extruded with the elastic body 170, the tightness degree of the joint with the first side surface of the first traction disc 115 and the second side surface of the second traction disc 135 is adjusted, and accordingly expected damping is provided for the rotation of the first rotating shaft 113 and the second rotating shaft 133. Generally, the locking device 10 may have an unlocked condition and a locked condition and may provide different degrees of damping at intermediate positions between the two.
The operation of the locking device 10 will now be described in detail with particular reference to fig. 2 and 3.
Fig. 2 shows a schematic view of the locking device 10 of fig. 1 in an unlocked state. Fig. 3 shows a schematic view of the locking device 10 of fig. 1 in a locked state. Fig. 2 and 3 are schematic structural views of the locking device 10 in fig. 1, which are rotated counterclockwise to make the second end of the locking device 10, i.e., the end of the brake disc 300, face out of the paper. The operation of the locking device 10 will be briefly described with reference to fig. 1 to 3, with the focus on the operation of switching between the locked state and the unlocked state.
When the endoscope locking device 10 needs to be locked, the driving rod 530 rotates clockwise along the handle 700 by a certain angle (from the position a to the position B as shown in fig. 2), the driving rod 530 drives the driving member 510 to rotate around the second rotating shaft 133, and simultaneously drives the hanging wall column 519 on the driving member 510 to slide in the long hole 350, and drives the brake disc 300 to rotate clockwise around the positioning hole 370, so that the brake disc 300 contacts and presses the elastic body 170, and the first side surface of the first traction disc 115 and the second side surface of the second traction disc 135 which are oppositely arranged are in contact and pressed, so that rotation resistance is generated between the brake disc 300 and the first rotating shaft 113 and the second rotating shaft 133, and since the brake disc body 310 is a wedge-shaped body, the more the brake disc body is in contact with the opposite gap positions of the first side surface of the first traction disc 115 and the second side surface of the second traction disc 135, the more tightly the brake disc body is attached to the side surfaces until the first rotating shaft 113 and the second rotating shaft 133 cannot rotate under the resistance, the first traction disc 115 and the second traction disc 135 is in the friction position, so that the endoscope locking device is locked in the left and right traction tube, and the endoscope locking state, and the endoscope locking angle is achieved. Referring to fig. 2 and 3, which are the process of changing from fig. 2 to fig. 3, it can be seen that the brake disc 300 is not in contact with the first side of the first traction disc 115 in the position of fig. 2, and is in contact with the first side of the first traction disc 115 in the position of fig. 3; the second traction disk 135 is obscured from view, but its actual variation is consistent.
When the endoscope locking device 10 needs to be unlocked, the driving lever 530 rotates along the handle 700 counterclockwise by a certain angle (from the position B to the position a as shown in fig. 3), the driving lever 530 drives the driving member 510 to rotate around the second rotating shaft 133, and simultaneously drives the hanging wall column 519 on the driving member 510 to slide in the long hole 350, so as to drive the brake disc 300 to rotate around the positioning hole 370 counterclockwise, thereby causing the brake disc 300 to be separated from the elastic body 170, and to realize separation from the first side surface of the first traction disc 115 and the second side surface of the second traction disc 135, so as to eliminate friction with the first traction disc 115 and the second traction disc 135, and the friction loaded on the first traction disc 115 and the second traction disc 135 gradually decreases until the friction disappears (the friction disappears after the brake disc 300 is separated from the first side surface of the first traction disc 115 and the second side surface of the second traction disc 135), so that the locking device is separated from the above locking state, and enters the above non-locking state. At this time, the first traction disk 115 and the second traction disk 135 can flexibly rotate along with the operation of the operator on the first rotating wheel 111 and the second rotating wheel 131; the traction wire related to the traction disc can be flexibly wound and retracted under the traction of the traction disc, so that the angle of the endoscope lens can be flexibly adjusted. Referring to fig. 2 and 3, which are the process that changes from fig. 3 to fig. 2, it can be seen that the brake disc 300 is in contact with the first side of the first traction disc 115 in the position of fig. 3 and is not in contact with the first side of the first traction disc 115 in the position of fig. 2; the second traction disk 135 is obscured from view, but its actual variation is consistent.
In the middle of the locking and unlocking positions, the shifting lever 530 can be operated to be positioned in the middle of the positions A and B, so that the locking device is in different damping states, and different tightness degrees of the adjusting rotating wheel can be obtained according to the requirement of rotating the rotating wheel. The locking device can set the endoscope in a proper state according to the requirement when the endoscope is adjusted, can freely adjust the angle of the lens of the endoscope through the rotating wheel when unlocked, and can ensure that the endoscope is in a fixed state when locked, so that the angle of the lens cannot be changed; if the damping state is between the two, the required hand feeling of the dial rotating wheel can be provided for an operator, so that the operator can conveniently operate the dial rotating wheel.
In the above embodiment, in principle, the combination of the shift lever 530 and the driving element 510 forms a lever mechanism, and since the shift lever 530 is longer and is equivalent to the long arm end of a lever, the brake disc 300 can be easily swung by shifting the driving element 510 and driving the brake disc 300 through the suspension wall column 519, and conversely, the shift lever 530 is difficult to be driven by the brake disc 300 being swung; moreover, the cantilever rod 519 is tightly matched with the long hole 350 of the brake disc 300, so that a certain friction force exists between the cantilever rod and the long hole, and the shift lever 530 is equivalent to provide a load for blocking the movement of the brake disc 300, so that the brake disc 300 is difficult to move due to looseness; that is to say, the locking device has a good locking characteristic, and the shift lever 530 can be shifted to any shifted position, and can hover without external force, and cannot be easily loosened.
The first embodiment described above is a preferred embodiment, and it is obvious that there may be other variations in its basic principle. For example, the wheel assembly 100 includes a first wheel assembly, i.e., the locking device can only adjust the angle of the endoscope in one dimension. Of course, there are other possible variations. For example, the first wheel 111 and the second wheel 131 already mentioned are in opposite positions, rather than being at the same end as in the present embodiment.
In the above embodiment, it is further preferable that the locking device for endoscope adjustment further divides the brake disc and the brake disc driving assembly into two groups, and provides the damping for the first rotating shaft and the second rotating shaft, so as to realize independent control and adjustment of the observation angles of the endoscope in the first dimension and the second dimension. The second dimension is in a different direction dimension than the first dimension.
The brake disc 300 can be divided from top to bottom along the position of the spacer 150 in fig. 1, and divided into a first brake disc portion and a second brake disc portion, and referring to the structure of the locking device in fig. 1, the position and the structure of the first brake disc driving assembly can be similar to the brake disc driving assembly 500 (right side in fig. 1) in fig. 1, and the second brake disc driving assembly can be located on the other side (left side in fig. 1) of the first brake disc driving assembly; the first brake disc part is arranged on one side of the first side surface of the first traction disc, and the second brake disc part is arranged on one side of the second side surface of the second traction disc; the first brake disc driving assembly can adjust the tightness degree of the fit between one part of the brake disc and the first side surface of the first traction disc, so that damping according with the expectation is provided for the first rotating shaft; rotation of the first traction disk is used to adjust the first traction wire, thereby adjusting the viewing angle of the endoscope in a first dimension. The second brake disc driving assembly can adjust the degree of tightness of fit of the second brake disc part and one side of the second side surface of the second traction disc, so that expected damping is provided for the second rotating shaft; rotation of the second traction disk is used to adjust the second traction wire and thereby adjust the viewing angle of the endoscope in the second dimension.
The preferred embodiment described above enables the endoscope to achieve independent adjustment of the viewing angle in one dimension while ensuring that the viewing angle in another dimension is fixed.
