Description

Quick connector for endoscope insertion part

Technical Field

The utility model relates to a quick-operation joint device, concretely relates to quick-operation joint of endoscope portion of inserting.

Background

The industrial endoscope is a novel nondestructive testing instrument which integrates multiple technologies of optics, precision machinery and electronics. The method is widely applied to the manufacturing and maintenance of industries such as petroleum, chemical engineering, aerospace, automobile and the like.

For example, the overhaul of large generators by power plants. Wherein, the inspection of large holes, deep holes and main steam thick pipelines related to the power generation stator or the inspection of retrieving fallen parts requires the inspection of an endoscope with a longer insertion part with a working length of 8000 mm-15000 mm or the inspection of an endoscope with a thicker insertion part with a diameter of 12 mm-18 mm; for the examination of cracks in small oil pipes and nozzles of large generators and nozzle clogging, it is necessary to examine an endoscope of a small insertion part having a diameter of 4mm to 8mm and an endoscope of an insertion part having a short working length of 600mm to 2000 mm. Therefore, for the nondestructive inspection of the large whole equipment, 2 sets (at least) to 6 sets of different-specification insertion portion endoscopes are required to finish the inspection of the whole equipment.

The prior art endoscopes have the following disadvantages:

first, the main body part and the insertion part of the endoscope main body are not interchangeable and are in a fixed design structure, and the insertion part cannot be pulled out quickly and cannot be replaced by another insertion part with another specification in time for immediate use. In addition, in most endoscopes, the connection between the rear joint (connector) of the insertion tube (hose) and the endoscope main body seat in the prior art is prone to loosening and self-rotation. The reason is that: when the rear joint of the insertion pipe is inserted into the joint hole of the main body seat of the endoscope main body, 3 screw holes are uniformly distributed on the side wall of the connecting hole of the main body seat, wherein 3 designed conical end set screws are fixed in the V-shaped annular groove in the middle section of the outer diameter of the rear joint part of the insertion pipe for connection.

Secondly, the obvious defect of the joint structure is that the screw thread outer diameter of the designed fixing screw cannot be large because the structural space at the joint of the insertion tube and the endoscope main body is small, the designed conical end jacking screw of M2.0 or M2.5 has low fixing strength, and because the insertion tube is long, when the endoscope main body is used, the front end of the long insertion tube is bound to be self-weight to drop, when the endoscope main body is held by hands to operate, the dropping force of the insertion tube is transmitted to the joint of the rear joint of the insertion tube from the front end of the insertion tube and is transmitted to 3 conical end jacking screws of M2.0 or M2.5, the conical end jacking screws are repeatedly used for dozens of times, the conical end jacking screws are also repeatedly stressed or vibrated, even after the fixing screws are coated with oil thread glue, the deformation of the small fixing screws in the V-shaped groove of the joint sometimes occurs to be loosened because of the dropping force of the weight of the insertion part, and the 3 conical end jacking screws are slightly loosened, the insertion tube is then rotated by the adapter. When the insertion tube of the endoscope is used, the insertion tube is loosened or rotated, the use quality of the endoscope is directly influenced, and the endoscope needs to be disassembled, disassembled and overhauled in severe cases.
