One end of the locking block 5003 extends into the interior of the hole 4002. By sliding the locking block 5003 inside the cavity 5002, one end of the locking block 5003 extends into the interior of the hole 4002, which facilitates fixing the inner shell 5001 inside the outer shell 4001 and prevents relative rotation between the two, thus maintaining the stability of the endoscope camera 200. Furthermore, by applying pressure to the locking block 5003 by the pressing plate 4003, the locking block 5003 can retract into the interior of the cavity 5002, which facilitates the separation of the cable body 100 and the endoscope camera 200.
[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Example 2
[0034] Please see Figures 1-5As one embodiment of this utility model, a sealing gasket 600 is further fitted on the outer wall of the docking mechanism 500. One side of the sealing gasket 600 is in contact with one end of the anti-rotation mechanism 400. The use of the sealing gasket 600 improves the sealing performance between the docking mechanism 500 and the anti-rotation mechanism 400. A connector assembly 300 is provided inside one end of the cable body 100. The connector assembly 300 includes an inner ring 3001, and one end of the cable body 100 communicates with the inner ring 3001. An outer cylinder 3003 is fitted onto the outer wall of the inner ring 3001. Through the cooperation of the inner ring 3001 and the outer cylinder 3003, one end of the cable body 100 can be connected to the drive device. A clamp 3004 is installed on the inner wall of the outer cylinder 3003. An annular groove 3002 is opened on the outer wall of the inner ring 3001 to engage with the clamp 3004. Through the cooperation of the annular groove 3002 and the clamp 3004, the outer cylinder 3003 can rotate outside the inner ring 3001.
[0035] Example 3
[0036] Please see Figures 1-5 As an embodiment of this utility model, further, the cable body 100 is provided with a wire core 700 inside. The wire core 700 includes a core body 7001. The outer wall of the core body 7001 is fitted with an insulating layer 7002. The insulating layer 7002 is used to wrap and protect the core body 7001. The outer wall of the button plate 4003 is fitted with an anti-detachment ring 4004. The anti-detachment ring 4004 is slidably connected inside the hole 4002. The installation and use of the anti-detachment ring 4004 prevents the button plate 4003 from detaching from the hole 4002. A spring 5004 is connected inside the cavity 5002. One end of the spring 5004 is connected to one side of the locking block 5003. The elastic action of the spring 5004 on the locking block 5003 ensures that the locking block 5003 always faces the inside of the hole 4002. A filler is provided between the outer wall of the insulating layer 7002 and the inner wall of the cable body 100. The filler helps to keep the wire core 700 stable.
[0037] Specifically, the working principle of this endoscope camera cable sealing anti-rotation device is as follows: First, check the structure of the anti-rotation device for integrity. Only after ensuring the structure is intact should it be used. The locking block 5003 slides inside the cavity 5002, allowing one end of the locking block 5003 to extend into the hole 4002. This facilitates fixing the inner shell 5001 inside the outer shell 4001, preventing relative rotation between the two and maintaining the stability of the endoscope camera 200. Furthermore, the pressure applied by the pressing plate 4003 to the locking block 5003 causes it to retract into the cavity 5002, thus facilitating the connection between the cable body 100 and the endoscope. The cameras 200 are separated from each other and are used in conjunction with the sealing gaskets 600 to improve the sealing between the docking mechanism 500 and the anti-rotation mechanism 400. The inner ring 3001 and the outer cylinder 3003 work together to allow one end of the cable body 100 to dock with the drive device. The annular groove 3002 and the clamp 3004 work together to allow the outer cylinder 3003 to rotate outside the inner ring 3001. At the same time, the elastic action of the spring 5004 on the locking block 5003 ensures that the locking block 5003 always faces the inside of the hole 4002. The installation of the anti-detachment ring 4004 prevents the pressing plate 4003 from detaching from the hole 4002.
