[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the utility model and do not constitute a limitation on the utility model.

[0028] like Figure 1 to Figure 2 As shown, in order to achieve the above-mentioned purpose, the utility model proposes a locking device for an endoscope, comprising:

[0029] A clamping assembly is sleeved on the central long axis of the endoscope head end angle adjustment device, and can clamp or loosen the adjustment part for adjusting the endoscope head end angle;

[0030] The knob adapter 50 is sleeved on the central long axis and can rotate relative to the central long axis;

[0031] A knob fixing seat 40 is sleeved on the central long axis and is used to press the knob adapter 50 onto the clamping assembly so that when the knob adapter 50 rotates, the clamping assembly is driven to clamp or release the adjusting portion for adjusting the angle of the endoscope head end; and

[0032] The knob panel 20 is provided with a limiting notch 22 , and the knob adapter 50 is embedded in the limiting notch 22 .

[0033] Specifically, the clamping assembly is sleeved on the central long axis of the endoscope lens end angle adjustment device, and can clamp or loosen the adjustment part for adjusting the angle of the endoscope lens end, and the clamping assembly adopts at least one of the height adjustment sheet 60, the disc spring 70, and the friction sheet 80. The clamping assembly locks or unlocks the angle of the endoscope lens by increasing or decreasing the pressure between the adjustment part for adjusting the angle of the endoscope lens end.

[0034] The knob adapter 50 is in the shape of a flat oval disk, with a hole in the middle to be sleeved on the central long axis. The knob adapter 50 can rotate freely around the central long axis.

[0035] The knob fixing seat 40 is in the shape of a ring, and its size is slightly larger than the hole in the middle of the knob adapter 50. The knob fixing seat 40 is sleeved on the central long axis. The knob fixing seat 40 can make the knob adapter 50 close to the clamping assembly. When the knob fixing seat 40 is tightened, the rotation of the knob adapter 50 will be transmitted to the clamping assembly, thereby tightening or loosening the adjustment part for adjusting the angle of the endoscope head end.

[0036] The knob panel 20 is annular and is provided with a limiting notch 22. The outer edge of the knob adapter 50 can be embedded in the limiting notch 22, and the knob adapter 50 can be driven to rotate by rotating the knob panel 20.

[0037] The clamping assembly is directly sleeved on the central long axis and contacts with the adjusting part for adjusting the angle of the endoscope head end; the knob adapter 50 is also sleeved on the central long axis, located above the clamping assembly, and contacts with the clamping assembly through the knob fixing seat 40; the knob fixing seat 40 is sleeved on the central long axis and located above the knob adapter 50, and the knob adapter 50 is fastened to the clamping assembly; the knob panel 20 is provided with a limiting notch 22, and the knob adapter 50 is embedded in the limiting notch 22, and the knob adapter 50 is driven to rotate through the knob panel 20. When the operator rotates the knob panel 20, the knob panel 20 will transmit the rotational force to the knob adapter 50, and the rotation of the knob adapter 50 will transmit the rotational force to the clamping assembly, so that it presses or loosens the adjusting part for adjusting the angle of the endoscope head end.

[0038] By adopting the above technical solution, the knob adapter 50 is driven by the knob panel 20, and the clamping assembly is squeezed or released by the knob adapter 50. The design of this mechanical locking mechanism makes the device structure simple and reliable, thereby reducing the failure rate and extending the service life of the device.

[0039] In one embodiment of the present application, it also includes:

[0040] The knob inner shell 10 is provided with a limiting groove, and a limiting protrusion 21 which can be inserted into the limiting groove is provided on the side of the knob panel 20 away from the knob adapter. The knob inner shell 10 is also provided with an extension portion 12, and the extension portion 12 passes through the knob adapter 50 to limit the knob panel 20 between the knob adapter 50 and the knob inner shell 10. The knob inner shell 10 is partially abutted against the side of the knob fixing seat 40 away from the knob adapter 50.

[0041] Specifically, the knob inner shell 10 is an operating handle, and a limiting groove is provided on the side of the knob inner shell 10 that contacts the knob panel 20. The limiting groove is two blind holes 11 that are arranged opposite to each other. The limiting groove is used to cooperate with the limiting protrusion 21 of the knob panel 20, so as to facilitate the knob inner shell 10 and the knob panel 20 to maintain synchronous movement during the rotation process; the extension part 12 on the knob inner shell 10 can pass through the knob adapter 50 and fix the knob panel 20 between the knob adapter 50 and the knob inner shell 10, so that it does not shift during the operation.

[0042] The operation process is:

[0043] When the operator rotates the knob inner shell 10, the knob inner shell 10 drives the knob panel 20 to rotate, and the knob panel 20 drives the knob adapter 50 to rotate, so that the knob adapter 50 can press or release the pressing assembly. Since the knob inner shell 10 partially abuts against the side of the knob fixing seat 40 away from the knob adapter 50, and the knob inner shell 10 is connected to the knob adapter 50, and the knob adapter 50 is limited by the knob fixing seat 40, it is ensured that the knob inner shell 10 will not loosen or shift.

[0044] By adopting the above technical solution and providing the knob inner shell 10, it is convenient for operators to operate, thereby ensuring the high efficiency of the equipment.

[0045] In one embodiment of the present application, a positioning protrusion 41 is provided on one side of the knob fixing seat 40 close to the knob adapter 50 , and a positioning notch is provided on the knob adapter 50 . The positioning protrusion 41 is arranged in the positioning notch to limit the deflection angle of the knob adapter 50 .

[0046] Specifically, the positioning protrusion 41 on the knob fixing seat 40 is located at a side close to the knob adapter 50. There are one or more positioning protrusions 41, which are used to limit the knob adapter 50 from excessive rotation.

[0047] The knob adapter 50 is provided with a positioning notch corresponding to the positioning protrusion 41 on the knob fixing seat 40. When the knob adapter 50 is installed on the knob fixing seat 40, the positioning protrusion 41 fits into the positioning notch.

[0048] The connection between the two is achieved by matching the positioning protrusion 41 on the knob fixing seat 40 with the positioning notch on the knob adapter 50. This connection method not only ensures the stability of the knob adapter 50 in the knob fixing seat 40, but also allows it to rotate as needed to adjust the angle of the endoscope.

[0049] By adopting the above technical solution, the locking of the endoscope head end can be controlled more accurately by limiting the deflection angle of the knob adapter 50. The coordinated use of the positioning protrusion 41 and the positioning notch effectively prevents the operator from over-rotating when locking the angle, thereby protecting the mechanical parts of the endoscope from damage due to excessive force.

[0050] In one embodiment of the present application, the knob fixing seat 40 is locked on the central long axis by a locking nut 30 .

[0051] Specifically, the anti-loosening nut 30 is intended to prevent the nut from gradually loosening due to vibration or frequent rotation of the knob, thereby ensuring that the knob fixing seat 40 can still be firmly fixed on the central long axis during long-term use.

[0052] In one embodiment of the present application, the pressing assembly includes:

[0053] A height adjustment piece 60 is sleeved on the central long axis, and a first side of the height adjustment piece 60 abuts against the knob adapter 50. An inclined groove is provided on the first side, and the depth of the inclined groove increases successively in a clockwise or counterclockwise direction. An adjustment column that can slide along the length direction of the inclined groove is provided on the knob adapter 50, and a side of the height adjustment piece 60 opposite to the first side can abut against an adjustment portion for adjusting the angle of the endoscope head end.

[0054] Specifically, the height adjustment sheet 60 is sleeved and fixed on the central long axis, and can move vertically on the central long axis to adjust the height. The first side of the height adjustment sheet 60 contacts the knob adapter 50, and when the knob adapter 50 rotates, it is convenient to drive the height adjustment sheet 60 to move downward. The inclined groove is provided on the first side of the height adjustment sheet 60, and the groove depth gradually increases in the clockwise or counterclockwise direction. The adjustment column on the knob adapter 50 can slide along the inclined groove, thereby allowing the adjustment column to move along the inclined groove when the knob is rotated, thereby changing the vertical position of the height adjustment sheet 60. The other side of the height adjustment sheet 60, that is, the side opposite to the first side, abuts against the adjustment part for adjusting the angle of the endoscope head end, so that the locking of the endoscope head end angle can be achieved according to the change of the height of the adjustment sheet.

[0055] By adopting the above technical solution, a combination design of an inclined slot and an adjusting column is adopted, so that the height adjustment can be controlled by the precision of the knob rotation, making the endoscope locking device smaller and easier to operate.

[0056] In one embodiment of the present application, the pressing assembly further includes:

[0057] The disc spring 70 is sleeved on the central long axis and is arranged between the height adjustment piece 60 and the adjustment part for adjusting the angle of the endoscope head end.

[0058] Specifically, the disc spring 70 adopts the disc spring 70 commonly used in the prior art. The disc spring 70 is sleeved on the central long axis and is located between the height adjustment plate 60 and the adjustment part for adjusting the angle of the endoscope head end. In this way, the disc spring 70 directly makes physical contact with these two parts. When the height adjustment plate 60 moves up and down (driven by the knob adapter 50 through the inclined groove and the adjustment column), pressure is applied to the disc spring 70. The changing pressure will in turn achieve the locking of the angle of the endoscope head end.

[0059] By adopting the above technical solution, due to the design of the disc spring 70, a larger stroke can be obtained under the same rotation amount, making the locking of the angle of the endoscope head end more efficient.

[0060] In one embodiment of the present application, the pressing assembly further includes:

[0061] The friction plate 80 is sleeved on the central long axis and is arranged between the disc spring 70 and the adjustment part for adjusting the angle of the endoscope head end.

[0062] Specifically, the friction plate 80 is sleeved on the central long axis, and the friction plate 80 is located between the disc spring 70 and the adjusting part for adjusting the angle of the endoscope head end, so that the friction plate 80 can directly contact the disc spring 70 and the adjusting part for adjusting the angle of the endoscope head end.

[0063] The disc spring 70 provides the required pressure so that the friction plate 80 is in close contact with the adjusting portion for adjusting the angle of the endoscope head end, thereby achieving a stable locking effect by increasing the friction between the adjusting portion and the endoscope head end.

[0064] By adopting the above technical solution, the friction plate 80 is combined with the disc spring 70, which can not only provide the necessary pressure, but also ensure that the angle adjustment of the endoscope head end is stably locked at the required position by increasing the friction force, avoiding deviation caused by external factors such as vibration.

[0065] In one embodiment of the present application, a receiving space is provided on the friction plate 80 , and the disc spring 70 is disposed in the receiving space.

[0066] Specifically, placing the disc spring 70 in the accommodation space within the friction plate 80 can better integrate the components, reduce the space required for the overall system, make the design more compact, and save internal space.

[0067] The present application also discloses an endoscope, comprising a locking device for an endoscope as described in any one of the above items.

[0068] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
