[0031] See also Figures 1 to 3 The endoscope 100 of the present invention includes a pipe connector 10, an insertion portion 20, and a handle 30. The proximal end 21 of the insertion portion 20 is assembled on the handle 30, and the handle 30 provides support for the insertion portion 20. Since the specific structure of the insertion portion 20 is well known in the art, it will not be described in detail here. In addition, the handle 30 is provided with four correspondingly arranged side-by-side plugs 31. Each plug 31 is mated with the first end 12a of a corresponding plug body 12 described below. The state is shown in FIG. Figure 4As shown, the corresponding plugs 31 are assigned different functions according to actual needs. For example, one plug 31 is responsible for connecting with the cleaning gas circuit, another plug 31 is responsible for connecting with the cleaning water circuit, another plug 31 is responsible for connecting with the auxiliary water supply circuit, and the remaining plug 31 is responsible for connecting with the suction pipeline. Obviously, according to actual needs, the number of plugs 31 can also be three, five or six. Figure 2 and Figure 4 In addition, the handle 30 is further provided with a sleeve structure 32 for being fitted with the sleeve cavity 11b described below, and a matching card structure 33 for being engaged with the engaging structure 11c described below. Optionally, as an example, the matching card structure 33 is located on the side wall of the sleeve structure 32 to improve the smoothness and reliability of the engagement between the matching card structure 33 and the engaging structure 11c.

[0032] Recombination Figure 4 、 Figure 7 、 Figure 9 and Figure 10 The pipe joint 10 comprises a joint body 11 and four plug bodies 12 arranged side by side on the joint body 11. The joint body 11 is provided with a sleeve cavity 11b which passes through the first end face 11a of the joint body 11. Figure 10 As an example, the outer contour of the sleeve cavity 11b in the transverse direction is a trapezoid. This design makes the insertion between the pipe connector 10 and the handle 30 have a fool-proof function, thereby ensuring the reliability of the insertion between the pipe connector 10 and the handle 30. Obviously, according to actual needs, the outer contour of the sleeve cavity 11b in the transverse direction can also be other shapes with a fool-proof function, so it is not limited to Figure 10 It should be noted that the horizontal direction here refers to Figure 10 In the middle, the center line of the insert body 12 (see Figure 10 The direction is perpendicular to the center line of the insert body 12 on the right side.

[0033] At the same time, the connector body 11 is provided with a snap-fit ​​structure 11c exposed in the sleeve cavity 11b and adjacent to the first end face 11a. Figure 4 and Figures 7 to 10As an example, the engaging structure 11c is a engaging protrusion protruding from the sleeve cavity 11b, and an inclined structure 112 is provided on the side of the cavity side wall 111 of the sleeve cavity 11c that is away from the sleeve cavity 11c. The inclined structure 112 is inclined toward the cavity side wall 111 close to the sleeve cavity 11b along the direction in which the sleeve cavity 11b passes through the first end face 11a (i.e., indicated by arrow B); with the help of the inclined structure 112, the smoothness of the engaging protrusion passing over the sleeve structure 32 and engaging with the matching card structure 33 is improved, thereby improving the smoothness of the insertion between the pipe connector 10 and the handle 30; when the engaging structure 11c is a engaging protrusion, correspondingly, the matching card structure 33 is a engaging groove.

[0034] The first end 12a of the plug-in body 12 protrudes from the sleeve cavity 11b, so that the first end 12a of the plug-in body 12 and the plug 31 provided on the handle 30 can be plugged into each other; the second end 12b of the plug-in body 12 protrudes from the connector body 11, so that the external cleaning air path, cleaning water path, auxiliary water path and suction pipeline can be assembled with the pipeline connector 10 in a unified manner; the interior of the plug-in body 12 is also provided with a through channel 12c that completely penetrates the plug-in body 12, and the through channel 12c is connected to the sleeve cavity 11b from the first end 12a of the plug-in body 12 to meet the need for the external cleaning air path, cleaning water path, auxiliary water path and suction pipeline to be connected with the corresponding plug-in body 12. Specifically, Figure 4 、 Figure 6 、 Figure 7 and Figure 8 As an example, the pipe joint 10 further includes a pipe seal 13 built into the sleeve cavity 11b, and the pipe seal 13 further has four pairs of plug holes 131 (see FIG. Figure 9 ), the first end 12a of each plug-in body 12 is inserted into a corresponding plug-in hole 131 with an interference fit, and each plug-in plug 31 is inserted into a corresponding plug-in hole 131 with an interference fit, so that the corresponding positions between all plug-in bodies 12 and plug-in plugs 31 are sealed by a single pipe seal 13 to prevent leakage. This simplifies the number of pipe seals 13 used and correspondingly simplifies the structure of the pipe joint 10. More specifically, as follows:

[0035] like Figure 9 As shown, as an example, the pair of sockets 131 includes a first pair of sockets 1311 and a second pair of sockets 1312 with different apertures. The first end 12a of the plug body 12 is inserted into the first pair of sockets 1311 in an interference fit, and the second pair of sockets 1312 faces the first end surface 11a. Correspondingly, the plug 31 is inserted into the second pair of sockets 1312 in an interference fit. Figure 4 As shown; optionally, Figure 9As an example, the aperture of the second pair of jacks 1312 is larger than the aperture of the first pair of jacks 1311, and the center lines of the holes of the second pair of jacks 1312 and the first pair of jacks 1311 are (see Figure 9 This design can accurately control the position of the first end 12a of the plug 12 inserted into the pipeline seal 13, as well as the position of the plug 31 inserted into the pipeline seal 13, thereby ensuring the reliability of the fit between the pipeline seal 13, the first end 12a of the plug 12 and the plug 31. Figure 9 As an example, the pipe seal 13 is respectively provided with a chamfered structure 132 for enlarging the ends of the first pair of holes 1311 and the second pair of holes 1312. With the help of the chamfered structure 132, on the one hand, it is convenient to insert the plug 31 and the first end 12a of the plug body 12 into the pipe seal 13, and on the other hand, the first end 12a of the plug body 12 and the plug 31 can be guided and corrected during the insertion process, so that the first end 12a of the plug body 12 can be accurately inserted into the first pair of holes 1311, and the plug 31 can be accurately inserted into the second pair of holes 1312.

[0036] Another example Figure 9 As shown, as an example, the insert 12 and the connector body 11 form an integral structure together, so that the insert 12 and the connector body 11 can be manufactured using an integral forming method, such as but not limited to injection molding, thereby simplifying the manufacturing process of both. In addition, the insert 12 is arranged to extend along the direction in which the sleeve cavity 11b passes through the first end face 11a, so that the first end 12a of the insert 12 can better fit with the pipe seal 13. In addition, the pipe seal 13 and the snap-fit ​​structure 11c are arranged in sequence along the direction in which the sleeve cavity 11b passes through the first end face 11a, so that the pipe seal 13 does not protrude from the connector body 11, better meeting the requirement of "the sleeve structure 32 provided on the handle 30 is inserted into the sleeve cavity 11b, and the matching card structure 33 in the sleeve cavity 11b is snap-fitted with the snap-fit ​​structure 11c".

[0037] Compared with the prior art, the invention adopts the method of "the pipe joint 10 includes a joint body 11 and a plurality of plug bodies 12 arranged side by side on the joint body 11, the joint body 11 is provided with a sleeve cavity 11b that passes through the first end face 11a of the joint body 11, the joint body 11 is provided with a clamping structure 11c that is exposed in the sleeve cavity 11b and is adjacent to the first end face 11a, the first end of the plug body 12 protrudes into the sleeve cavity 11b, the second end 12b opposite to the plug body 12 protrudes from the joint body 11, and the interior of the plug body 12 is further provided with a through channel 12c that completely passes through the plug body 12, and the through channel 12c is provided with a through channel 12c that completely passes through the plug body 12. The first end 12a of the plug body 12 is connected to the sleeve cavity 11b. In this way, the pipe connector 10 integrates the interfaces for water and gas, auxiliary water supply, and suction. The sleeve cavity 11b and the engaging structure 11c enable the pipe connector 10, which integrates the interfaces for water and gas, auxiliary water supply, and suction, to be plugged and unplugged with the corresponding structure (e.g., the sleeve structure 32) of the handle 30 of the endoscope 100. Therefore, by plugging the pipe connector 10 with the corresponding structure of the handle 30, the interfaces for water and gas, auxiliary water supply, and suction can be uniformly plugged and unplugged at one time, thereby simplifying the operation process and structure.

[0038] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved. At the same time, what is disclosed above is only the preferred embodiment of the present invention, and of course it cannot be used to limit the scope of rights of the present invention.
