Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 A rotatable endoscope docking handle includes a housing 1, a bushing 2 threaded into one end of the housing 1, a locking nut 3 rotatably sleeved at the end of the bushing 2 away from the housing 1, the locking nut 3 having anti-slip texture on the outside for anti-slip function, a male plug housing 4 threaded into the bushing 2, a core sleeve 5 threaded into the male plug housing 4, a guide rod 6 threaded into the end of the core sleeve 5 near the locking nut 3, and an optical fiber bundle 7 inserted into the guide rod 6;

[0025] In this embodiment, the guide rod 6 is threaded with a pin core seat 8 for installing pins 9. Multiple pins 9 are fixedly inserted in the pin core seat 8. The pins 9 are connected to the wires 11 in the insertion tube 16. Multiple control buttons 12 are embedded on the outer shell 1 for inputting control commands. Fastening screws 10 are fixedly connected to the inner wall of the outer shell 1. The core sleeve 5 is provided with fastening screw holes corresponding to the fastening screws 10, which effectively prevents the core sleeve 5 from moving relative to the outer shell 1.

[0026] In this embodiment, a connecting sleeve 13 is rotatably connected to the end of the outer shell 1 away from the locking nut 3. A rotating sleeve 14 is rotatably sleeved on the outside of the connecting sleeve 13. A soft rubber ring 20 is fixedly sleeved on the outside of the rotating sleeve 14 to improve the rotation feel of the rotating sleeve 14. A second screw 21 is threaded into the rotating sleeve 14. A second annular groove corresponding to the second screw 21 is provided on the connecting sleeve 13. A fixing sleeve 15 is inserted into the rotating sleeve 14. An insertion tube 16 is fixed inside the fixing sleeve 15.

[0027] In this embodiment, the fixing sleeve 15 is located in the inner hole of the left end of the core sleeve. Multiple O-rings 22 are embedded between the fixing sleeve 15 and the inner hole of the left end of the supporting core sleeve to improve the relative rotation flexibility between the fixing sleeve 15 and the core sleeve 5. The outer thread of the right end of the core sleeve 5 is threaded into the inside of the connecting sleeve 13. A stop pin 18 is provided in the first annular groove at the right end of the fixing sleeve 15. A first screw 19 corresponding to the stop pin 18 is threaded into the core sleeve 5. One end of the first screw penetrates the inner wall of the outer shell 1 and extends outward.

[0028] In this embodiment, the rear docking part includes a heat insulation sleeve 23, which serves as a heat insulation function. A female plug shell 24 is threadedly inserted into one end of the heat insulation sleeve 23 near the front docking part. A female plug core seat 25 is fixedly inserted into the female plug shell 24. A plurality of female plugs 26 corresponding to the pins 9 are inserted into the female plug core seat 25. An intermediate sleeve 27 is inserted into the female plug shell 24. A female plug support sleeve 28 is threadedly sleeved onto one end of the female plug shell 24 located inside the heat insulation sleeve 23. A light source seat 29 is fixedly connected inside the female plug support sleeve 28. A light source 30 is fixedly connected to the light source seat 29.

[0029] In this embodiment, the cross-section of the guide rod 6 is D-shaped, and the hole in the female plug core seat 25 is also D-shaped. When the two are inserted in alignment, the D-shape serves as an orientation, ensuring that the male plug and the corresponding female pin are inserted in opposite directions. The inner side of the locking nut 3 is threaded, and the outer left side of the female plug core seat 25 is threaded accordingly. When the thread is screwed in, the right end of the guide rod 6 will reach the light source. The light passes through the optical fiber inside the guide rod 6 and reaches the lens component at the front end of the insertion tube 16 for illumination. The docking of the male and female pins transmits the signal from the wire at the front end of the insertion tube 16 to the rear display device. By rotating the locking nut 3 in the opposite direction, the male and female plugs move in opposite directions, and the front and rear docking parts of the handle separate.

[0030] In this embodiment, due to the step blocking effect formed by the core sleeve 5 and the connecting sleeve 13, the movement of the insertion tube fixing sleeve 15 along the axial direction is restricted, and it can only rotate around the axis. The fixing sleeve 15 is provided with a rotating sleeve 14 on the outside, and a second side plane is provided on its inner hole. The fixing sleeve 15 is provided with a corresponding first side plane. When the rotating sleeve 14 is rotated, the fixing sleeve 15 will rotate together due to the restriction effect of the side plane.

[0031] In this embodiment, the upper end face of the stop pin 18 is lower than the outer circle of the fixing sleeve 15 at this location. The first screw 19 passes through the through hole of the outer shell 1 and through the corresponding screw hole on the core sleeve 5, with the head of the first screw 19 reaching the bottom of the first annular groove. If the first screw 19 is tightened so that its head is pressed against the annular groove, the fixing sleeve 15 is locked and cannot be rotated. If the first screw 19 is loosened so that its head leaves the bottom of the annular groove by a gap but is not completely removed from the annular groove, when the fixing sleeve 15 rotates, the first screw 19 will block the stop pin, preventing its rotation angle from exceeding 360 degrees, thus avoiding damage to the internal wires of the insertion tube 16 due to excessive twisting.

[0032] In this embodiment, the screw 2 positioned in the middle of the annular groove 2 serves to restrict movement and prevent the rotating sleeve from detaching from the left end. The O-ring between the insertion tube fixing sleeve and the core sleeve provides damping and improves the feel of rotation. The soft rubber ring 20 serves to cover and enhance aesthetics, while also providing a smoother feel during rotation. Since the rear coupling sleeve contains a light source, which is a heating element and can cause temperature rise, the heat insulation sleeve prevents direct hand contact with the metal to avoid potential discomfort from high temperatures.

[0033] In this embodiment, the endoscope transmits the acquired image information to the rear display through the slender insertion tube on the handle and the probe at the front end. It can observe areas that are not easily visible to the naked eye and has wide applications in medical and industrial inspections.

[0034] In this embodiment, the front and rear connecting parts of the handle are separable. The front part is equipped with an insertion tube component, which is the working part and is generally relatively expensive and easily damaged. The separable front part facilitates its replacement, improving maintenance convenience. At the same time, it allows for easy selection of front parts with insertion tubes featuring different characteristics, enhancing the applicability of the device. In addition, the insertion tube, which can rotate around its axis, facilitates the acquisition of multi-directional image information.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
