[0037] The utility model provides an optical bayonet 100, which is suitable for connecting with an optical structure 200 on an optical adapter 1000. The optical bayonet 100 and the eyepiece cover of the endoscope are connected to each other, so that the endoscope is fixed on the optical adapter 1000 to better collect image information of the affected part.

[0038] Specifically, see Figures 1 to 3 The optical bayonet 100 includes a housing structure 1 and a clamping structure 2. The housing structure 1 has a clamping cavity suitable for clamping an endoscope therein. The housing structure 1 includes a clamping bracket 11 arranged in an annular shape, and a clamping ring 12 rotatably sleeved on the outer peripheral side of the clamping bracket 11. The clamping bracket 11 is suitable for connecting with the optical structure 200. The clamping ring 12 is provided with a driving part 1222. The inner ring side of the clamping bracket 11 and the inner ring side of the clamping ring 12 jointly form the clamping cavity, and a receiving groove is formed on one side of the clamping cavity; the clamping structure 2 includes a clamping member 21, and the clamping member 21 is provided with a transmission part 23 matched with the driving part 1222. The clamping member 21 has a connecting end and a The free end, the connecting end is rotatably connected to the clamping bracket 11, the transmission part 23 is located between the connecting end and the free end, the clamping member 21 has a clamping state in which at least a part of it can be extended from the accommodating groove to extend into the clamping cavity, and an unlocking state in which the clamping member 21 is retracted into the accommodating groove; wherein, the clamping ring 12 is subjected to an external force to rotate relative to the clamping bracket 11 and drive the transmission part 23 to rotate together, and under the cooperation of the driving part 1222 and the transmission part 23, the clamping member 21 can be driven to switch from the clamping state to the unlocking state, and when the external force applied to the clamping ring 12 is removed, the clamping member 21 can automatically switch from the unlocking state to the clamping state.

[0039] In this embodiment, the card cavity on the card shell structure 1 can be used for the endoscope to be inserted into it, and then the endoscope is fixed by the card structure 2, so that endoscopes of different sizes can be locked and unlocked; moreover, the card shell structure 1 includes a relatively rotating card bracket 11 and a card ring 12, and the driving part 1222 on the card ring 12 cooperates with the transmission part 23 on the card member 21, so that when the card ring 12 is subjected to an external force to rotate relative to the card bracket 11, the driving part 1222 can be driven to rotate, and the card member 21 is driven to rotate relative to the card bracket 11 under the cooperation of the driving part 1222 and the transmission part 23, so that the card member 21 has a card state in which at least part of it can extend from the accommodating groove to extend into the card cavity, thereby locking the endoscope on the optical bayonet 100; and the card member 21 has an unlocking state that is retracted in the accommodating groove. state, thereby facilitating the replacement of the endoscope, and the operation is simple and convenient, and the clamping ring 12 can automatically return to the clamping state when no external force is applied, and the operation is more labor-saving; further, the clamping member 21 is rotatably connected to the clamping bracket 11 through one end, and the transmission part 23 is arranged at a position between the two ends of the clamping member 21. Obviously, compared with the scheme in which the transmission part 23 and the rotating part are respectively arranged at the two ends of the clamping member 21, when unlocking, in the technical scheme provided by the utility model, the force arm between the unlocking operation point and the rotating point of the clamping member 21 is shorter, so that the unlocking driving force is greater, and the driving force required to switch the optical bayonet 100 from the clamping state to the unlocking state is greater. Therefore, correspondingly, when the clamping member 21 is in the clamping state, the clamping force acting on the endoscope is also greater, so that the optical bayonet 100 has a greater locking force on the endoscope and a better locking effect, so as to ensure that the endoscope is not easy to fall off during operation. Moreover, when the lever arm is shorter, while keeping the size of the optical bayonet 100 unchanged, the movable range of the clamping member 21 can be larger, so that the clamping amount can be larger, thereby meeting the installation requirements of more types of endoscopes and having better adaptability.

[0040] For the card shell structure 1, combined with Figure 1 and Figure 2 As shown, the housing structure 1 is roughly annularly arranged, and its inner ring side is for the endoscope to be inserted therein. The clamping bracket 11 includes a clamping body arranged in an annular shape, and a clamping end wall arranged at one axial end of the clamping body, and the clamping end wall is suitable for being detachably connected with the optical structure 200. Specifically, the clamping body has a first end and a second end arranged along its axial direction, the second end is the front end of the clamping body, and the clamping end wall is arranged at the first end of the clamping body, and the clamping end wall is at least partially hollowed out to reduce the weight and avoid wind resistance when the endoscope is inserted.

[0041] Combination Figure 1As shown in , it should be noted that when the optical bayonet 100 is in normal use, the side facing the endoscope is set as the front, and the end of the optical bayonet 100 connected to the optical structure 200 is the rear end. The axial direction of the housing structure 1 is along the front-to-back direction, and the description of the relevant directions in the utility model shall be referred to in this regard unless otherwise specified.

[0042] Furthermore, combined with Figure 1 , Figure 6 and Figure 7 As shown, the clamping ring 12 includes a first clamping ring 121 and a second clamping ring 122 connected to each other. The first clamping ring 121 and the second clamping ring 122 are rotated together to clamp the clamping bracket 11 at both ends along its axial direction. The first clamping ring 121 is provided with a clamping protrusion 1212, and the clamping bracket 11 is provided with a slide groove 24. The clamping protrusion 1212 is extended along the circumference of the first clamping ring 121 and is slidably engaged with the slide groove 24. When the first clamping ring 121 is connected to the clamping bracket 11, the clamping protrusion 1212 is engaged with the slide groove 24, thereby preliminarily limiting the first clamping ring 121 and the clamping bracket 11 in the radial direction, and the first clamping ring 121 can rotate relative to the clamping bracket 11.

[0043] Furthermore, if Figure 7 As shown in, the second clamping ring 122 is arranged at the second end of the clamping bracket 11, and the second clamping ring 122 has a mounting surface 1221 which is arranged opposite to the front end surface of the second end, and the mounting surface 1221 and the front end surface of the second end are spaced to form the accommodating groove, and the driving part 1222 is arranged on the mounting surface 1221, and the clamping member 21 is arranged on the front end surface of the clamping bracket 11, when the clamping member 21 rotates relative to the clamping bracket 11, the free end of the clamping member 21 can extend out of the accommodating groove to extend into the clamping cavity, thereby abutting against the outside of the endoscope to be in a clamping state; or the clamping member 21 can be completely accommodated in the accommodating groove and does not protrude from the inner cavity wall of the clamping cavity, so that the clamping member 21 does not contact the endoscope, so that the endoscope can be pulled out from the clamping cavity to unlock the endoscope and replace the endoscope.

[0044] The second snap ring 122 is generally annular, and has a ring body and a ring side edge provided on the front end surface of the ring body, the ring side edge is also annular, the driving part 1222 is provided on the rear side of the ring side edge, the ring body is connected to the first snap ring 121, and is covered on the outer peripheral side of the clamping bracket 11, and the ring side edge and the front end surface of the clamping bracket 11 jointly form the accommodating groove. The clamping member 21 can be better exposed on the outside of the clamping bracket 11, so that assembly is more convenient.

[0045] Moreover, an operating part is provided on the outer peripheral side of the ring body, and the operating part includes a boss protruding radially on the outer peripheral side of the ring body, and the end surface of the boss facing away from the ring body is concave-convex. Preferably, there are two operating parts, and the two operating parts are symmetrically arranged on both sides of the ring body along the radial direction. When rotating the clamping ring 12, the user can press the concave-convex surfaces of the two operating parts with two fingers respectively, thereby driving the second clamping ring 122 to rotate, driving the first clamping ring 121 to rotate together, so that the optical bayonet 100 enters the unlocked state, and the unlocking operation is simple and labor-saving.

[0046] It can be understood that there are many configurations of the transmission part 23 and the driving part 1222. Preferably, Figure 2 and Figure 5 As shown, the transmission part 23 includes a boss 231 protruding from the clamping member 21, and the boss 231 is located at one end of the clamping member 21 along the axial direction of the clamping ring 12. Specifically, the boss 231 is protruding from the front side of the clamping member 21; the driving part 1222 includes a clamping groove 1222a provided on the clamping ring 12, the boss 231 is clamped in the clamping groove 1222a and can move along the clamping groove 1222a, and the clamping groove 1222a is provided on the On the mounting surface 1221 of the second snap ring 122, along the rotation direction of the snap ring 12, the snap groove 1222a is gradually inclined inward, so that when the snap ring 12 rotates, the snap groove 1222a is driven to rotate, so that the boss 231 can move along the snap groove 1222a, and the boss 231 is displaced in the radial direction, thereby driving the snap member 21 to rotate in a direction away from the middle, so that the free end of the snap member 21 moves toward the middle away from the card cavity to achieve unlocking.

[0047] Moreover, the optical bayonet 100 also includes a reset structure 3, which connects the snap ring 12 and the snap component 21. When the external force applied to the snap ring 12 is removed, the snap component 21 is driven to automatically switch from the unlocked state to the engaged state under the action of the reset structure 3. There is no need to manually provide a driving force on the snap ring 12, so that the snap component 21 can be automatically engaged with the endoscope, making the snap connection and locking more convenient and more labor-saving.

[0048] The clamping member 21 is provided with a rotating shaft 22, and the clamping bracket 11 is provided with a rotating hole. The rotating shaft 22 is rotatably sleeved in the rotating hole and can extend from the rotating hole. The rotating shaft 22 rotates relative to the rotating hole, so that the clamping member 21 can rotate relative to the clamping bracket 11. The reset structure 3 includes an elastic telescopic member 31, one end of which is connected to the rotating shaft 22, and the other end of which is connected to the clamping ring 12. When the clamping ring 12 is rotated by an external force and switches from the clamping state to the unlocking state, the elastic telescopic member 31 is in an elastic force storage state. When the external force on the clamping ring 12 is removed, the clamping ring 12 can be restored from the unlocking state to the clamping state under the action of the elastic restoring force of the elastic telescopic member 31. The snap ring 12 can be manually rotated to unlock. When the hand is released, the snap ring 12 can be automatically reset under the action of the elastic telescopic member 31, and the snap member 21 can be automatically extended to snap onto the endoscope, thereby fixing the endoscope and making the operation more labor-saving.

[0049] Preferably, if Figure 6 and Figure 7 As shown, the elastic telescopic member 31 is configured as a telescopic spring, and the telescopic spring is extended along the outer peripheral side surface of the clamping bracket 11. Specifically, when the clamping ring 12 is rotated along the first direction, the boss 231 moves along the clamping groove 1222a, so that the telescopic spring is in a stretched or compressed state, and the clamping member 21 is in an unlocked state. When the clamping ring 12 is released, the elastic restoring force of the telescopic spring pushes the clamping ring 12 to rotate, so that the boss 231 is reset along the clamping groove 1222a, so that the clamping member 21 is restored to the clamping state. The first direction can be clockwise or counterclockwise. When the clamping member 21 is in the clamping state, as shown in FIG. Figure 3 As shown in FIG. 1 , the protrusion 231 is located at one end of the clamping groove 1222a. When the clamping member 21 is in the unlocked state, as shown in FIG. Figure 5 As shown in , the boss 231 is located at the other end of the clamping groove 1222a, so that when the clamping ring 12 is manually rotated, the clamping ring 12 cannot be rotated if the rotation direction is wrong.

[0050] A positioning column 1211 extending along the axial direction is provided on the first clamping ring 121 , and a clamping hole is provided on the positioning column 1211 . One end of the elastic telescopic member 31 is hooked at the clamping hole, so that the connection of the telescopic spring is more stable and reliable.

[0051] Moreover, since the shape of the eyepiece cover of the endoscope is roughly conical, in order to prevent the endoscope from easily falling out of the cavity opening of the card cavity, the card connector 21 is provided with a bevel on the side facing away from the cavity opening of the card cavity. The bevel is located at the free end of the card connector 21 and on the edge of the card connector 21 close to the cavity, thereby increasing the contact area and extrusion area between the card connector 21 and the eyepiece cover, thereby increasing the tightness.

[0052] In addition, if Figure 1 , Figure 3 and Figure 5 As shown, the clamping structure 2 includes a plurality of clamping parts 21, and the plurality of clamping parts 21 are arranged at intervals along the circumference of the clamping ring 12, and the rotation points of the plurality of clamping parts 21 are on the same circumferential surface. The plurality of clamping parts 21 are uniformly clamped on the circumferential side of the endoscope, so that the force at various places on the circumferential side of the endoscope is more uniform and the clamping stability is better.

[0053] The utility model also provides an optical adapter 1000, such as Figure 8 As shown in the figure, the optical adapter 1000 includes an optical structure 200, and an optical bayonet 100 connected to the optical structure 200. The clamping bracket 11 of the optical bayonet 100 is connected to the optical structure 200. The endoscope is fixed by the optical bayonet 100. The image information collected by the endoscope can be processed by the optical structure 200 to make the observed image information clearer.

[0054] Obviously, the above described embodiments are only a part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the utility model.
