[0033] 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.
[0034] The core of this invention is to provide a capsule endoscope that reduces the processing difficulty of the middle shell.
[0035] For a specific embodiment of the capsule endoscope provided by this utility model, please refer to the following: Figures 1 to 5 It includes an outer shell 1 and a capsule core 5.
[0036] The outer shell 1 includes a middle shell 2, a first sealing member 3, and a second sealing member 4. The middle shell 2 is a cylindrical structure that runs through the middle shell along the axial direction X and is open at both ends. The capsule core 5 is inserted into the middle shell 2. The first sealing member 3 and the second sealing member 4 are fixedly connected to the two ends of the middle shell 2 along the axial direction X and cooperate to limit the capsule core 5 along the axial direction X.
[0037] After the first sealing member 3 is fixed to one axial port of the middle shell 2, the capsule core 5 can be inserted into the middle shell 2 along the axial direction X through the other axial port of the middle shell 2 until it abuts against the first sealing member 3 along the axial direction X. Then, the second sealing member 4 can be fixed to the other axial port of the middle shell 2. The capsule core 5 is an integral structure and can be assembled into the middle shell 2 as a whole.
[0038] When assembling the product, the first sealing piece 3 can be fixed to one axial port of the middle shell 2 to block one axial end on the middle shell 2. At this time, the first sealing piece 3 can serve as the axial X positioning structure of the capsule core 5. Then, the capsule core 5 is inserted into the middle shell 2 until the capsule core 5 and the first sealing piece 3 abut against each other along the axial X. After that, the second sealing piece 4 is fixedly connected to the middle shell 2 to realize the assembly of the capsule core 5 on the middle shell 2. At this time, the middle shell 2, the capsule core 5, the first sealing piece 3, and the second sealing piece 4 are connected to form the main module of the capsule endoscope.
[0039] In this embodiment, the first cap 3, the capsule core 5, and the second cap 4 can be assembled sequentially on the middle shell 2. Since the first cap 3 can serve as an axial X positioning reference to position the capsule core 5 in the axial X assembly of the middle shell 2, and the capsule core 5 is limited by the cooperation of the first cap 3 and the second cap 4 to prevent the capsule core 5 from detaching from the middle shell 2 in the axial X direction, the setting of the limiting structure on the inner wall of the middle shell 2 can be reduced or eliminated, the processing difficulty of the middle shell 2 and the assembly difficulty of the capsule core 5 can be reduced, and the assembly efficiency and accuracy can be guaranteed.
[0040] In this configuration, the first cover 3 is bonded and fixed to the middle shell 2, and the second cover 4 is also bonded and fixed to the middle shell 2. This design avoids structural damage to the first cover 3 and the middle shell 2 during connection. Of course, in other embodiments, the first cover 3 and / or the second cover 4 can also be connected to the middle shell 2 using screws or other methods.
[0041] To further facilitate the assembly of capsule core 5, such as Figure 2 and Figure 3 As shown, the first sealing member 3 includes a first end cap 31 and a first cylindrical body 32. A first through hole 311 is provided through the middle of the first end cap 31, and the first cylindrical body 32 is connected to the first through hole 311 and placed outside the middle shell 2. The first end cap 31 is fixedly connected to an axial port of the middle shell 2. The capsule core 5 has a central protrusion 51 at one end in the axial direction X.
[0042] During assembly, such as Figure 3As shown, during the process of inserting the capsule core 5 into the middle shell 2 along the axial direction X, the central protrusion 51 can enter the first cylindrical body 32 through the first through hole 311, and the capsule core 5 can move to abut against the first end cap 31 along the axial direction X. At this time, the central protrusion 51 and the first cylindrical body 32 can play a guiding role, reducing or avoiding the swaying of the capsule core 5 relative to the axial direction. A camera 52 can be installed on the central protrusion 51 of the capsule core 5.
[0043] In addition, such as Figure 2 and Figure 3 As shown, the first sealing member 3 also includes a second cylindrical body 33. The first cylindrical body 32 and the second cylindrical body 33 are respectively fixed to both sides of the first end cap 31 in the axial direction X. The second cylindrical body 33 extends into the middle shell 2 in the axial direction X, and one end of the capsule core 5 extends into the second cylindrical body 33 in the axial direction X. By adding the second cylindrical body 33, the stability of the connection between the first sealing member 3 and the middle shell 2 and the capsule core 5 can be improved.
[0044] Among them, such as Figure 3 As shown, the second cylindrical body 33 and the capsule core 5 abut against each other radially, which can further improve the stability of the assembly of the second cylindrical body 33 and the capsule core 5. Specifically, the capsule core 5 can radially press the second cylindrical body 33 against the middle shell 2.
[0045] In addition, such as Figure 2 As shown, an installation platform 312 is also fixedly provided on the outer peripheral surface of the first end cover 31. The installation platform 312 abuts against an axial end face of the middle shell 2 along the axial direction X, which can realize the axial positioning of the first cover 3 when it is assembled into the middle shell 2.
[0046] To facilitate the assembly of the capsule core 5 into the middle shell 2, such as Figure 3 As shown, the diameter of the inner wall of the middle shell 2 gradually decreases from one end to the other along the axial direction X, and the first sealing member 3 is fixed to the small-diameter end of the middle shell 2. Of course, in other embodiments, the inner wall of the middle shell 2 can be a cylindrical surface with the same diameter at all points.
[0047] Furthermore, the outer casing 1 also includes a first cap body 7 and a second cap body 6. For example... Figure 5 As shown, the first cap 7 and the second cap 6 respectively cover the two ends of the middle shell 2 in the axial direction X, and the first cap 7 covers the first sealing member 3, and the second cap 6 covers the second sealing member 4, so as to effectively protect the capsule core 5.
[0048] Both the first cap 7 and the second cap 6 are transparent, allowing a camera to be mounted at either end of the capsule core 5 along the axial direction or for light to pass through. Specifically, cameras 52 are mounted at both ends of the capsule core 5 along the X-axis to form a dual-lens capsule endoscope.

When an element is referred to as "connecting" another element, it can be directly connected to the other element or there may be an intervening element.
