[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Combine the following Figure 1-Figure 8 , through specific embodiments and application scenarios, an endoscope provided by an embodiment of the utility model is described in detail.

[0033] like Figure 1 As shown, the utility model provides an endoscope, comprising: a mirror tube body 1, a rotating disk 2, an adjusting rope 3, a rotating handle 4 and a locking member 5, the rotating disk 2 is inserted into the mirror tube body 1, the adjusting rope 3 is sleeved on one end of the rotating disk 2 located inside the mirror tube body 1, the rotating handle 4 is fixedly connected to one end of the rotating disk 2 located outside the mirror tube body 1; the rotating disk 2 is threadedly matched with the locking member 5; the locking member 5 has a limiting structure, and as the locking member 5 rotates, the limiting structure presses the rotating handle 4 against the outer wall of the mirror tube body 1 to achieve locking of the rotating handle 4.

[0034] It is understandable that if Figure 2 As shown, the rotating handle 4 is fixedly connected to the rotating disk 2, and is used to drive the rotating disk 2 to rotate. The rotating disk 2 includes a rotating disk and a connecting platform 21. The connecting platform 21 is convexly arranged on the rotating disk, and the two can be an integrally connected structure. Among them, the rotating disk is accommodated in the interior of the mirror tube body 1, and the adjustment rope 3 is laid on the rotating disk. As the rotating disk rotates, the length of the adjustment rope 3 changes, so that the curvature of the mirror tube body 1 changes.

[0035] like Figure 2 As shown, the connecting platform 21 is penetrated through the outer wall of the mirror tube body 1. The turntable is fixedly connected to the rotating handle 4 through the connecting platform 21. Optionally, one end of the connecting platform 21 away from the turntable is inserted into the rotating handle 4 to achieve a fixed connection between the rotating disk 2 and the rotating handle 4. Alternatively, the rotating handle 4 can also be directly welded to the connecting platform 21, as long as the rotating handle 4 and the rotating disk 2 can be fixedly connected.

[0036] When the user needs to adjust the curvature of the mirror tube body 1, the user directly rotates the rotating handle 4. After the curvature of the mirror tube body 1 is adjusted to the target curvature, the user no longer pushes the rotating handle 4, and the rotating handle 4 is fixed at the current position.

[0037] Furthermore, if Figure 3 As shown, the endoscope provided by the utility model further includes a locking member 5. The locking member 5 is used to lock the rotating handle 4 in the above position to prevent the rotating handle 4 from being slightly deflected due to the reaction force of the adjusting rope 3 or mechanical error during use, thereby affecting the locking of the curvature of the mirror tube body 1.

[0038] Specifically, the locking member 5 has a limiting structure. At least a portion of the locking member 5 is threadedly connected to the connecting platform 21. As the locking member 5 is screwed in toward the mirror tube body 1, the limiting structure and the rotating handle 4 are closely abutted to press the rotating handle 4 against the outer wall of the mirror tube body 1. Therefore, under the action of the locking member 5, the rotating handle 4 is always fixed at the current position and will not deflect at will.

[0039] Of course, when the user needs to adjust the curvature of the mirror tube body 1 , the user only needs to rotate the locking member 5 in a direction away from the mirror tube body 1 , and the limiting structure and the connecting platform 21 are separated to provide a movable space for the rotating handle 4 .

[0040] The utility model provides an endoscope, wherein a rotating disk 2 is inserted into a mirror tube body 1, an adjusting rope 3 is sleeved on one end of the rotating disk 2 located inside the mirror tube body 1, and a rotating handle 4 is fixedly connected to one end of the rotating disk 2 located outside the mirror tube body 1, so that the rotating disk 2 is driven to rotate by the rotating handle 4, and then the adjusting rope 3 is driven by the rotating disk 2 to move, so that it is convenient for a user to adjust the curvature of the mirror tube body 1 according to actual needs; after the curvature of the mirror tube body 1 is adjusted, a locking member 5 is threadedly matched with the rotating disk 2, and the locking member 5 has a limiting structure. As the locking member 5 rotates, the limiting structure presses the rotating handle 4 against the outer wall of the mirror tube body 1 to realize the locking of the rotating handle 4, and the rotating handle 4 will not deflect spontaneously, thereby realizing the locking of the curvature of the mirror tube body 1.

[0041] In some embodiments, Figure 4 As shown, the rotating disk 2 has a through hole 211. At least part of the hole wall of the through hole 211 has an internal thread, one end of the locking member 5 is inserted into the through hole 211, and the other end of the locking member 5 is provided with a limiting structure, and the locking member 5 has an external thread that matches the internal thread.

[0042] It is understandable that the through hole 211 is provided on the end surface of the connecting platform 21 away from the turntable. A part of the hole wall of the through hole 211 is provided with an internal thread. Optionally, the hot melt nut 22 can be welded to the end of the through hole 211 close to the turntable. The part of the locking member 5 inserted into the through hole 211 is provided with an external thread. The thread of the hot melt nut 22 is adapted to the external thread. When locking the rotating handle 4, the end of the locking member 5 with the external thread is inserted into the through hole 211 and screwed in along the direction toward the mirror tube body 1 so as to be threadedly connected with the hot melt nut 22; the other end of the locking member 5 is provided with a limiting structure. As the locking member 5 is screwed in, the limiting structure abuts against the rotating handle 4, thereby pressing the rotating handle 4 against the outer wall of the mirror tube body 1.

[0043] In some embodiments, Figure 4 and Figure 5As shown, the locking member 5 includes a bolt 51 and a locking handle 52. The screw rod of the bolt 51 is threadedly matched with the through hole 211, and the locking handle 52 is sleeved on the end cap of the bolt 51.

[0044] It is understandable that the thread of the bolt 51 is adapted to the thread of the hot melt nut 22. The screw of the bolt 51 is inserted into the through hole 211 and is matched with the thread of the hot melt nut 22.

[0045] In this embodiment, the limiting structure is the end cap of the bolt 51 and the locking handle 52. Figure 6 and Figure 7 As shown, the locking handle 52 is sleeved on the end cap of the bolt 51, and the step surface formed by the end cap of the bolt 51 and the screw rod is flush with the wall surface of the locking handle 52 facing the mirror tube body 1. As the screw rod is screwed in, the end cap of the bolt 51 and the locking handle 52 both abut against the rotating handle 4, and together press the rotating handle 4 against the outer wall of the mirror tube body 1.

[0046] At the same time, the locking handle 52 can facilitate the user to screw the bolt 51 so as to quickly and conveniently lock and release the rotating handle 4.

[0047] Furthermore, if Figure 6 and Figure 7 As shown, the endoscope further includes a connecting pin 6. The locking handle 52 is provided with a first connecting hole, and the end cap is provided with a second connecting hole. The locking handle 52 is sleeved on the end cap, and the connecting pin 6 is inserted into the first connecting hole and the second connecting hole in sequence, thereby achieving a fixed connection between the locking handle 52 and the end cap of the bolt 51. Of course, the end cap of the bolt 51 and the locking handle 52 can also be directly welded together.

[0048] In other embodiments, the locking member 5 is a fastening nut. Correspondingly, the outer wall of the connecting platform 21 is provided with a thread adapted to the fastening nut. When the rotating handle 4 is locked, the fastening nut is sleeved on the connecting platform 21 and screwed to a corresponding position to press the rotating handle 4 against the outer wall of the mirror tube body 1.

[0049] like Figure 3 As shown, in order to ensure aesthetics, the position of the internal thread of the through hole 211, as well as the number of matching turns of the internal thread and the external thread, etc., can be reasonably set during production design to ensure that the central axis of the locking handle 52 and the rotating handle 4 are parallel. However, due to errors in component processing and assembly errors, when the bolt 51 is screwed to the limit state, there may still be a small gap between the locking handle 52 and the rotating handle 4, resulting in the locking effect of the locking member 5 on the rotating handle 4 cannot be fully guaranteed; in addition, due to the existence of such a small gap, the locking handle 52 and the rotating handle 4 cannot be fully aligned, affecting the aesthetics of the entire endoscope.

[0050] Furthermore, if Figure 5 and Figure 8 As shown, the utility model further includes an adjusting bolt 7 and an adjusting member 8. The adjusting bolt 7 is threadedly matched with the rotating handle 4, and the end of the adjusting bolt 7 abuts against the adjusting member 8. The rotating handle 4 is provided with a mounting groove 41, the notch of the mounting groove 41 faces the mirror tube body 1, and the adjusting member 8 is movably arranged in the mounting groove 41; as the adjusting bolt 7 is screwed in, the adjusting member 8 is pressed against the bottom of the mounting groove 41 to press the rotating handle 4 against the locking handle 52.

[0051] It is understandable that the adjusting bolt 7 is used to adjust the position of the adjusting member 8 so as to squeeze the rotating handle 4 through the adjusting member 8, thereby eliminating the small gap between the rotating handle 4 and the locking handle 52, ensuring that when the rotating handle 4 is locked, the central axes of the locking handle 52 and the rotating handle 4 are always parallel, thereby ensuring the aesthetics of the endoscope. Figure 8 As shown, the rotating handle 4 is provided with a mounting groove 41. The notch of the mounting groove 41 faces the mirror tube body 1. The groove wall of the mounting groove 41 is provided with a threaded hole adapted to the adjusting bolt 7. The adjusting member 8 is accommodated in the mounting groove 41. As the adjusting bolt 7 is screwed in, the adjusting bolt 7 abuts against the adjusting member 8 to push the adjusting member 8 to move toward the bottom of the mounting groove 41. Under the action of the adjusting member 8, the rotating handle 4 abuts against the end surface of the locking handle 52.

[0052] In some embodiments, the adjusting member 8 is a sliding block. The shape of the sliding block can be rectangular, triangular or other special shapes. The threaded hole is in the shape of an oblique hole. The adjusting bolt 7 is inserted into the threaded hole and is inclined to the rotating handle 4. That is, there is a certain angle between the central axis of the adjusting bolt 7 and the bottom of the mounting groove 41. As the adjusting bolt 7 is screwed in, the adjusting member 8 is pressed against the bottom of the mounting groove 41, so that the rotating handle 4 is abutted against the end face of the locking handle 52 to eliminate the small gap between the rotating handle 4 and the locking handle 52.

[0053] In other embodiments, Figure 8 As shown, the adjusting member 8 includes a first adjusting member 81 and a second adjusting member 82. The end of the adjusting bolt 7 abuts against the first adjusting member 81, the first adjusting member 81 has a first wedge-shaped surface, the second adjusting member 82 has a second wedge-shaped surface, the first wedge-shaped surface and the second wedge-shaped surface fit together, and the second adjusting member 82 is located between the first wedge-shaped surface and the bottom surface of the mounting groove 41.

[0054] The screwing direction of the adjusting bolt 7 is not parallel to the first wedge surface.

[0055] It is understandable that if Figure 8As shown, the first adjusting member 81 and the second adjusting member 82 have matching first wedge-shaped surfaces and second wedge-shaped surfaces. The first adjusting member 81 and the second adjusting member 82 are adjacently arranged along the extension direction of the mounting groove 41, and the first adjusting member 81 is located at one end close to the notch of the mounting groove 41, and the second adjusting member 82 is located at one end close to the bottom of the mounting groove 41.

[0056] The adjusting bolt 7 can be arranged perpendicular to the extending direction of the mounting groove 41 or at an acute or obtuse angle to the extending direction of the mounting groove 41 , as long as the screwing direction of the adjusting bolt 7 is not parallel to the first wedge surface.

[0057] The adjusting bolt 7 passes through the threaded hole and abuts against the first adjusting member 81 to push the first adjusting member 81 to move. The first wedge surface fits the second wedge surface, and under the pressure of the first adjusting member 81, the second adjusting member 82 is pressed toward the bottom of the installation groove 41, so that the rotating handle 4 abuts against the end surface of the locking handle 52 to eliminate the small gap between the rotating handle 4 and the locking handle 52.

[0058] In some embodiments, Figure 5 As shown, two sets of adjusting bolts 7 and adjusting members 8 are provided as a set, and the two sets of adjusting bolts 7 and adjusting members 8 are symmetrically arranged along the extending direction of the mounting groove 41 .

[0059] It is understandable that two sets of the above-mentioned adjusting bolts 7 and adjusting members 8 are symmetrically arranged on opposite sides of the rotating handle 4 to jointly press the rotating handle 4 to maintain the force balance of the rotating handle 4 and further eliminate the small gap between the rotating handle 4 and the locking handle 52.

[0060] Furthermore, if Figure 8 As shown, the endoscope further includes at least one pressing sheet 9. A portion of the pressing sheet 9 is fixed to the bottom of the mounting groove 41, and a gap is formed between another portion of the pressing sheet 9 and the bottom of the mounting groove 41 to form an accommodating groove, in which the second adjusting member 82 is accommodated.

[0061] It is understandable that the pressing piece 9 is used to limit the second adjusting member 82 to prevent the second adjusting member 82 from falling off. Specifically, the pressing piece 9 is in a folded shape. One end of the pressing piece 9 is fixed to the bottom of the mounting groove 41 by a fastener such as a bolt 51, and the other end has a certain gap with the bottom of the mounting groove 41, so that a receiving groove is formed between the pressing piece 9 and the bottom of the mounting groove 41. The second adjusting member 82 is received in the receiving groove and can move in the receiving groove.

[0062] In the above embodiment where two sets of adjusting bolts 7 and adjusting members 8 are provided, the middle of the pressing sheet 9 is fixed to the bottom of the mounting groove 41. There is a certain gap between the two ends of the pressing sheet 9 and the bottom of the mounting groove 41, forming two receiving grooves. The two second adjusting members 82 are respectively received in the two receiving grooves.

[0063] like Figure 4 and Figure 5 As shown, the endoscope further includes a gasket 10. The gasket 10 is sleeved on the portion of the rotating disk 2 extending out of the scope tube body 1, and the gasket 10 sandwiches the scope tube body 1 and the rotating handle 4.

[0064] It is understandable that the gasket 10 has sufficient supporting strength to further support and fix the rotating handle 4. Specifically, the gasket 10 is annular. Optionally, the size and shape of the gasket 10 are adapted to the rotating handle 4. For example, the gasket 10 is a circular plate, and the gasket 10 is a circular pad whose size and shape are consistent with the end of the rotating handle 4.

[0065] The gasket 10 is sleeved on the connecting platform 21. As the locking member 5 is continuously screwed into the through hole 211, the gasket 10 is sandwiched between the outer wall of the mirror tube body 1 and the end surface of the rotating handle 4, thereby increasing the friction between the mirror tube body 1 and the rotating handle 4 and improving the stability of the connection.

[0066] Specifically, in some embodiments, Figure 4 and Figure 5 As shown, the gasket 10 includes a flexible gasket 101 and a metal gasket 102. The flexible gasket 101 and the metal gasket 102 are stacked, the flexible gasket 101 is located at one end of the gasket 10 close to the mirror tube body 1, and the metal gasket 102 is located at one end of the gasket 10 close to the rotating handle 4.

[0067] It is understandable that the flexible gasket 101 is sleeved on the connecting platform 21 and is located on a side close to the mirror tube body 1. The flexible gasket 101 has a certain elasticity and can play a role of buffering protection to prevent the rotating handle 4 from scratching the outer wall of the mirror tube body 1. Optionally, the flexible gasket 101 is a rubber gasket. In another optional embodiment, the flexible gasket 101 is a latex gasket or a silicone gasket.

[0068] The metal gasket 102 is sleeved on the connecting platform 21 and is located on a side close to the rotating handle 4. The metal gasket 102 has a certain strength to support the rotating handle 4 and ensure the stability of the rotation of the rotating handle 4. Optionally, the metal gasket 102 is a stainless steel gasket.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
