Thus, a locking device is provided that can lock the up and down adjustment knobs of the electronic bronchoscope.
[0006] To this end, the utility model provides an up and down adjustment knob locking device for an electronic bronchoscope of this embodiment, which is suitable for being installed on an electronic bronchoscope, wherein the electronic bronchoscope has a handle, an up and down adjustment knob and a mounting shaft; and comprises:

[0008] The extrusion plate comprises an extrusion plate body and an extrusion structure movably connected to the extrusion plate body; the extrusion plate body is also rotatably mounted on the handle through the mounting shaft and is located on a side of the follower plate away from the handle;
[0009] The squeezing structure has a first state in which the squeezing disc is pressed toward the follower disc so that the squeezing disc squeezes and locks the follower disc; and a second state in which the squeezing structure moves away from the follower disc until the squeezing disc is no longer pressed so as to unlock the follower disc.
[0010] Furthermore, the locking connection structure includes:
[0011] A connecting plate, one end of which is fixedly connected to the follower disc body, and the other end of which extends in a direction away from the follower disc body;
[0012] The locking block is integrally formed at the other end of the connecting plate and is provided with a locking opening for inserting the free end of the up and down adjusting knob.
[0013] Furthermore, the extrusion structure comprises:
[0014] A fixed plate, one end of which is fixedly connected to the extrusion disc body, and the other end of which extends in a direction away from the extrusion disc body, and a first through hole is formed at the end thereof;
[0015] A second through hole, disposed on the handle and having an internal thread;
[0016] The extrusion bolt is rotatably installed inside the first hole and can be threadedly engaged with the second hole; when the extrusion bolt rotates, it can drive the fixing plate to drive the extrusion disc to move towards or away from the follower disc.
[0017] Furthermore, a lever handle is provided on the head of the extrusion bolt.
[0018] Furthermore, friction coatings are provided on the opposing surfaces of the extrusion disc and the follower disc.

[0023] The technical solution provided by the utility model has the following advantages:
[0024] The utility model discloses an up-and-down adjusting knob locking device for an electronic bronchoscope, which is suitable for being installed on an electronic bronchoscope. The electronic bronchoscope has a handle, an up-and-down adjusting knob and a mounting shaft; the device comprises a follower disk and a pressing disk; wherein the follower disk comprises a follower disk body and a locking connection structure arranged on the follower disk body; the follower disk body is suitable for being rotatably installed on the mounting shaft, and the locking connection structure is suitable for being locked and connected with the free end of the up-and-down adjusting knob so that the follower disk body can rotate synchronously with the up-and-down adjusting knob; the pressing disk comprises a pressing disk body and a pressing structure movably connected with the pressing disk body; the pressing disk body is also rotatably installed on the handle through the mounting shaft and is located on a side of the follower disk away from the handle; the pressing structure has a first state in which the pressing disk body is pressed toward the follower disk body so that the pressing disk body presses and locks the follower disk body; and a second state in which the pressing disk body is moved toward a direction away from the follower disk body until the pressing disk body is no longer pressed so as to unlock the follower disk body.
[0025] The utility model is a locking device for the up and down adjustment knob of an electronic bronchoscope. Pushing the up and down adjustment knobs can make the front end of the electronic bronchoscope bend in an arc shape, and the degree of the arc bending is related to the degree to which the up and down adjustment knobs are pushed up. When it is necessary to keep the front end of the electronic bronchoscope in a bent state at all times, the medical staff can adjust the up and down adjustment knobs into place, and then operate the squeezing structure to press the squeezing disc toward the direction of the follower disc, so that the squeezing disc squeezes and locks the follower disc, and keeps the locked state, so that the front end of the electronic bronchoscope always remains in a bent state; when it is no longer necessary for the front end of the electronic bronchoscope to remain in a bent state at all times, the medical staff can operate the squeezing structure to move the squeezing structure away from the follower disc until the squeezing disc is no longer pressed, so as to unlock the follower disc, so that the up and down adjustment knobs are no longer locked. In this way, when the front end of the electronic bronchoscope needs to remain in a bent state, the medical staff does not need to continuously apply force to the up and down adjustment knobs, so that the medical staff's hands can be relaxed, thereby ensuring the smooth progress of the operation.
