Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1 to 3, a portable docking structure for an endoscope system comprises a first docking member and a second docking member, wherein the first docking member is used for connecting a display screen in the endoscope system, and the second docking member is used for connecting a control handle in the endoscope system.

For convenient butt joint, the first butt joint piece comprises an annular sleeve shell 1, an annular elastic claw 5 and a clamping ring 4 which are arranged in the annular sleeve shell 1, the second butt joint piece comprises a cylindrical socket 13, and a clamping table protrusion 15 is arranged on the outer peripheral surface of the top of the cylindrical socket 13; the side wall of the annular casing 1 is provided with a bayonet 11, the annular elastic claw 5 comprises an opening section 52 and a clamping section 51 arranged corresponding to the bayonet 11, the clamping ring 4 is fixedly arranged on the clamping section 51, a bolt connection mode can be adopted, and the inner diameter of the clamping ring 4 is not less than the outer diameter of the clamping table protrusion 15; in a natural state, the opening section 52 is opened to the maximum under the action of elasticity of the opening section, is tensioned with the inner wall of the annular casing 1, the clamping section 51 is clamped on the bayonet 11, and the position of the clamping ring 4 is deviated from the center of the clamping table bulge 15, so that one part of the clamping ring 4 is clamped on the lower edge of the clamping table bulge 15 to realize fixation; when the clamping section 51 is pressed inwards, the opening section 52 of the ring-like elastic claw 5 can be gradually reduced, and the position of the clamping ring 4 gradually moves to the center of the clamping table bulge 15 until the clamping ring 4 and the clamping table bulge 15 are separated from each other.

In this embodiment, the clamping section 51 is opposite to the opening section 52, so that the annular elastic claw 52 has a symmetrical structure, the operation stability is better, and the production and installation are easier. In other embodiments, the pressing deformation and the resetting can be performed without facing the pressing deformation.

In order to press the clamping section 51 conveniently, the first butt joint piece is provided with a key 9 and an outer shell corresponding to the clamping section 51, the annular casing 1 is installed inside the outer shell, the outer shell is provided with an extending hole corresponding to the key 9, and the outer shell comprises a left outer shell 7 and a right outer shell 8 which are detachable, so that the clamping section is convenient to disassemble and assemble.

In order that the bottom of the ring-like elastic claw 5 can be supported, the inside of the annular housing 1 is further sleeved with a stop nut ring 6, and the ring-like elastic claw 5 is placed on the top surface of the stop nut ring 6.

The first butt joint piece further comprises a plug 2, the plug 2 is arranged inside the annular casing 1, an upper plug pin base 3 is arranged on the plug 1, a handle base 12 is connected to the bottom of the columnar socket 13, a lower plug pin base 14 matched with each other is arranged in the columnar socket 13 corresponding to the upper plug pin base 3, and after connection is completed, the plug 2 is inserted into the columnar socket 13 to connect the display and a circuit on the control handle together.

In order to further facilitate the butt joint, the outer diameter of the clamping platform bulge 15 is gradually reduced from the bottom end to the top end; when the specific butt joint, the operating handle of handheld endoscope inserts cylindrical socket 13 in annular cover shell 1, because the protruding 15 top of ka tai is smaller, it stretches into rand 4 very easily, continues to impel cylindrical socket 13, rand 4 is with class annular elasticity jack catch 5 receives the extrusion that comes from protruding 15 tops of ka tai and gradually become big and take place the displacement, and after card tai protruding 15 stretches into rand 4 completely, rand 4 resets, can with card tai protruding 15 is fixed firm, when needing to dismantle, presses button 9, rand 4 with card tai protruding 15 breaks away from each other, can break off both.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
