[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The core of the present invention is to provide a capsule shell, a capsule endoscope and an assembly method of the capsule shell, which can more conveniently connect the capsule rear shell and the capsule front cover to improve production efficiency.

[0034] For a specific embodiment of the capsule shell provided by the present invention, please refer to Figures 1 to 6 , including a first shell 1 and a second shell 2. In this embodiment, the first shell 1 is a capsule rear shell 5, and the second shell 2 is a light-transmitting capsule front cover 6. Of course, in other embodiments, such as Figure 7As shown, the first shell 1 may be a light-transmitting capsule front cover 6, and the second shell may be a capsule rear shell 5. The capsule rear shell 5 may be transparent or non-transparent.

[0035] The first shell 1 includes a first shell body 12 and an annular inner stop 11, wherein the inner stop 11 is arranged on the inner ring of the open end face of the first shell body 12, wherein the radially inner portion of the open end face of the first shell body 12 is the inner ring b, and the remaining outer portion is the outer ring a.

[0036] The open end of the second shell body 2 has an annular outer stop 21, the inner stop 11 is axially plugged into the outer stop 21 and fixedly connected by glue, and a glue-containing gap 4 is provided between the inner stop 11 and the outer ring of the end face of the open end of the first shell body 12 to accommodate overflowing glue.

[0037] During the assembly process, glue can be applied on the outer circumferential surface of the inner stop 11 and the inner circumferential surface of the outer stop 21 first, and then the inner stop 11 and the outer stop 21 can be plugged in. It should be noted that since the capsule front cover 6 and the capsule rear shell 5 need to be concentric after assembly to avoid dislocation, no gap should be reserved between the inner stop 11 and the outer stop 21 after assembly. Therefore, after plugging in, the glue left between the inner stop 11 and the outer stop 21 is relatively sparse.

[0038] During the plugging process, due to the fit between the inner stop 11 and the outer stop 21, part of the glue will remain between the inner stop 11 and the outer stop 21. By adding the glue-containing gap 4, the glue scraped out by the outer stop 21 will remain in the glue-containing gap 4 to enhance the firmness of the bonding between the capsule rear shell 5 and the capsule front cover 6, and have a waterproof effect, so that the capsule rear shell 5 and the capsule front cover 6 can be connected more conveniently, thereby improving production efficiency while ensuring assembly accuracy and ensuring the reliability of the connection.

[0039] Among them, Figure 2 and Figure 4 As shown, the outer circumferential surface of the inner stop 11 and the inner circumferential surface of the outer stop 21 are both inclined (inclined relative to the plugging direction) to provide guidance during the plugging process, further facilitating the assembly between the capsule rear shell 5 and the capsule front cover 6 .

[0040] In addition, the inner stop 11 is in the axial direction and close to the first housing 1 ( Figure 6 The outer stop 21 is a tapered part with a wall thickness gradually decreasing in the axial direction and in the direction close to the second housing 2 (in the downward direction), wherein the wall thickness of the inner stop 11 refers to the distance between the inner circumference and the outer circumference of the inner stop 11. Figure 6The tapered part has a wall thickness that gradually decreases in the upward direction, wherein the wall thickness of the outer stop 21 refers to the distance between the inner circumference and the outer circumference of the outer stop 21. The tapered structure of the inner stop 11 and the outer stop 21 facilitates demoulding of the capsule rear shell 5 or the capsule front cover 6 during injection molding, and has the advantage of not sticking to the mold, thereby improving the yield rate of the parts during production.

[0041] In addition, to further facilitate demoulding, e.g. Figure 4 As shown, the slope x of the outer circumference of the inner stop 11 and the inner circumference of the outer stop 21 is not less than 0.1°, and the thickness H of the axial end of the inner stop 11 away from the first shell body 12 is not less than 0.1 mm, thereby improving the part yield.

[0042] On the second housing 2, as Figure 2 As shown, the second shell 2 also includes a second shell body 22, and the outer stop 21 is provided on the outer ring c on the open end face of the second shell body 22, wherein, on the open end face of the second shell body 22, the radially inner portion is the inner ring d, and the remaining outer portion is the outer ring c. Since the space for the inner ring is reserved on the open end face of the second shell body 22, the thickness of the inner stop 11 can be accommodated, which is conducive to achieving a smooth transition between the inner circumferential surface of the inner stop 11 and the inner surface of the second shell 2.

[0043] like Figure 6 As shown, the capsule shell also includes a lamp cover 3, and the outer peripheral surface of the lamp cover 3 has a cover body convex ring 31. The lamp cover 3 is located in the cavity between the first shell 1 and the second shell 2, and the cover body convex ring 31 is clamped axially between the inner ring d and the inner stop 11 on the end surface of the opening end of the second shell body 22. At this time, the lamp cover 3 can be fixed with the help of the second shell 2 and the first shell 1.

[0044] In addition, the lamp panel cover 3 and the outer stop 21 clamp the inner stop 11 in the radial direction, which can further improve the tightness of the connection between the inner stop 11 and the outer stop 21 .

[0045] In addition to the above-mentioned capsule shell, the present invention further provides a capsule endoscope, which includes a capsule shell and a capsule core built into the capsule shell. The capsule shell can be specifically the capsule shell provided in any of the above embodiments, and the beneficial effects can be referred to the above embodiments accordingly. The structures of other parts of the capsule endoscope can refer to the prior art, which will not be described in detail herein.

[0046] In addition to the above-mentioned capsule shell and capsule endoscope, the present invention also provides an assembly method of the above-mentioned capsule shell, and the specific steps include:

[0047] Apply glue to the outer circumference of the inner stop 11 and the inner circumference of the outer stop 21;

[0048] An inner stop 11 and an outer stop 21 are provided along the axial direction.
