Description

Technical Field

[0001] The utility model relates to the technical field of endoscope auxiliary devices. Background Art

[0002] In terms of application, they can be simply divided into two categories, namely industrial endoscopes and medical endoscopes.

[0003] Regarding the types of industrial endoscopes, they are divided into optical endoscopes, fiber optic endoscopes, electronic endoscopes, CCD video endoscopes, CMOS video endoscopes, and electric 360° endoscopes based on the imaging form. They are divided into high-frequency fluorescent lamp endoscopes, fiber optic halogen lamp endoscopes, and LED endoscopes based on the type of endoscope light source.

[0004] Regarding the classification of medical endoscopes, according to their development and imaging structure, they can be roughly divided into three categories: hard tube endoscopes, optical fiber (hose-type) endoscopes and electronic endoscopes

[0005] During the inspection of industrial equipment, pipeline inspection is particularly important. When troubleshooting problems in the pipeline, an endoscope is needed to deeply explore the interior of the pipeline. Since the existing guide mechanism has a fixed length, it is not possible to increase or decrease the length of the guide mechanism. Therefore, it is not convenient to make the guide mechanism conform to the length of the pipeline, and it is not convenient to insert the endoscope into the pipeline for convenient movement and rotation. Utility Model Content

[0006] The utility model aims to provide a guiding mechanism for an endoscope, so as to overcome the defect that the length of the guiding mechanism is inconvenient to adjust.

[0007] The technical solution to achieve the above-mentioned purpose is: a guiding mechanism of an endoscope, comprising a catheter and a steering bend, the top end of the catheter and the upper end of the steering bend are connected to a plurality of array-distributed plug plates, the outer wall of the plug plate is provided with a limiting through hole, the bottom end of the catheter is provided with a plurality of card slots, the outer wall of the card slot is provided with an inner groove, the side wall of the inner groove is connected to a limiting spring, the bottom end of the limiting spring is connected to a limiting block, the outer wall of the limiting block is slidably connected to the inner groove, the side wall of the limiting block is connected to a round rod, and the outer wall of the round rod passes through the side wall of the catheter.

[0008] Preferably, an outer wall of one side of the limiting block close to the entrance end of the slot is provided with a slope.

[0009] Preferably, a placement groove is provided at the upper end of the inner wall of the limiting through hole, and a sliding groove is provided on the inner wall of the placement groove and the inner wall of the limiting through hole. A stopper is slidably connected to the inner wall of the sliding groove, and a support spring is connected to the outer wall of one side of the stopper, and one end of the support spring is connected to the side wall of the placement groove.

[0010] Preferably, an endoscopic probe is inserted into the interior of the catheter and the steering elbow.

[0011] Preferably, the outer wall of the conduit is threadedly connected with three screws, the outer wall of the screw is threadedly connected with a link, the bottom end of the link is connected with a fixing ring, the outer wall of the fixing ring is provided with an annular groove, and a plurality of balls are rotatably connected in the annular groove.

[0012] Preferably, one end of the round rod located inside the catheter is connected to a hemispherical block.

[0013] Preferably, the round rod and the hemispherical block are both covered with rubber soft sleeves.

[0014] Preferably, the depth of the placement groove is smaller than the depth of the limiting through hole.

[0015] The beneficial effects of the utility model are:

[0016] 1) Insert the plug plate into the slot. The plug plate will first push the limit block along the inclined surface. The limit block moves into the inner groove and squeezes the limit spring. When the limit block is aligned with the limit through hole, the stop block is pushed back into the placement slot. The limit block will be pushed into the limit through hole by the limit spring, thereby jamming the limit block. At the same time, the stop block will also squeeze the side wall of the limit block, further improving the stability of the limit block, thereby connecting the two conduits together and the conduit and the steering elbow together, thereby achieving the effect of adjusting the length of the guide mechanism.

[0017] 2) Put the fixing ring and the connecting ring on the outer wall of the catheter, and then screw the screws into the outer wall of the connecting ring and the catheter to fix the fixing ring and the connecting ring, and use the ball bearing to assist the rotation and movement of the catheter against the inner wall of the pipe.
