[0002] At present, in the process of assembling the endoscope, the socket of the light guide part needs to be plugged into the front end fixing ring. The outer diameter of the front end fixing ring is larger than the inner diameter of the clamping elastic part. During installation, the gap of the clamping elastic part needs to be manually enlarged and then forced into place, causing the clamping elastic part to be enlarged and unable to return to its original shape, and the consistency of manual assembly is poor. In addition, after long-term use, the clamping elastic part is plugged and pulled out many times. Due to extrusion and the unlimited position structure, its size will become smaller and smaller, eventually causing the clamping elastic part to become looser and looser during the plugging and pulling process, affecting the user experience.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] The core of the utility model is to provide an elastic component assembly device. During actual use, the contraction of the elastic component can be limited by a limiting structure to avoid affecting the experience of using the elastic component assembly device due to the elastic contraction of the elastic component.

[0035] Another core of the utility model is to provide an endoscope including the elastic member assembly device.

[0036] This specific embodiment discloses an elastic member assembly device, including a first plug-in mechanism 100 and a second plug-in mechanism 200 that are plug-matched, the first plug-in mechanism 100 is sleeved on the outer periphery of the second plug-in mechanism 200; the second plug-in mechanism 200 is provided with an insertion component 210 for inserting into the first plug-in mechanism 100, the insertion component 210 is provided with a mounting position 220 for installing an elastic member 300, a limiting structure 2201 is provided on the surface of the mounting position 220, and the limiting structure 2201 protrudes from the surface of the mounting position 220; the elastic member 300 is sleeved on the outer periphery of the mounting position 220, at least one notch 310 is provided along the circumference of the elastic member 300, and the limiting structure 2201 is located in the notch 310.

[0037] It should be noted that the thickness direction of the elastic member 300 in the present application can be limited to the radial direction of the plug assembly. Figure 1 , Figure 2 As shown, the radial direction of the plug assembly is the direction of the ray starting from the origin O in the plane where YZ is located; in this application, the width direction of the elastic member 300 is the axial direction of the plug assembly, as shown in FIG. Figure 2 The X direction is shown.

[0038] The notch 310 in this specific embodiment can penetrate the elastic member 300 in the width direction in the depth direction, so that the elastic member 300 is disconnected, or the notch 310 can not penetrate the elastic member 300 in the width direction in the depth direction, and only the notch 310 is set in the elastic member 300; in addition, the notch 310 needs to penetrate the surface of the elastic member 300 in the thickness direction that contacts the mounting position 220. In actual use, the limiting structure 2201 is located in the notch 310. In the initial installation state, the corresponding side surface of the notch 310 can be made to contact the limiting structure 2201. In the process of elastic contraction of the elastic member 300, the corresponding side surface of the notch 310 in the elastic member 300 contacts the limiting structure 2201. 00 generates an initial stage of elastic contraction, that is, the contraction of the elastic member 300 is limited; alternatively, in the initial installation state, a certain gap may be provided between the corresponding side of the notch 310 and the limiting structure 2201. During the elastic contraction of the elastic member 300, in the initial stage of elastic contraction of the elastic member 300, the gap size between the corresponding side of the notch 310 and the limiting structure 2201 is continuously reduced until the corresponding side of the notch 310 in the elastic member 300 contacts the limiting structure 2201. Thereafter, the elastic member 300 continues to elastically contract, and the limiting structure 2201 may limit the elastic contraction of the elastic member 300, thereby avoiding affecting the experience of using the elastic member assembly device due to the elastic contraction of the elastic member 300.

[0039] Furthermore, when the notch 310 does not completely penetrate the elastic member 300 in the width direction of the elastic member 300 , multiple notches 310 may be provided, with some notches 310 opening toward the first plug-in mechanism 100 and other notches 310 opening away from the first plug-in mechanism 100 .

[0040] In the process of using the elastic part assembly device provided in this specific embodiment, it is first necessary to sleeve the elastic part 300 on the outer periphery of the installation position 220, and make the limiting structure 2201 located in the notch 310, and insert the second plug-in mechanism 200 installed with the elastic part 300 into the first plug-in mechanism 100. During the repeated plugging and unplugging process, due to the setting of the limiting structure 2201, the elastic part 300 will be blocked by the limiting structure 2201 when shrinking. When the elastic part 300 shrinks to contact with the limiting structure 2201, the limiting structure 2201 contacts with the elastic part 300, which can effectively limit the shrinkage of the elastic part 300, so that the size of the elastic part 300 is maintained within an appropriate range, avoiding the elastic shrinkage of the elastic part 300 affecting the experience of using the elastic part assembly device.

[0041] In a specific embodiment, if Figure 4 As shown, the elastic member 300 is an open ring structure with an opening, and both ends of the open ring structure in the length direction are respectively in contact with the two side surfaces of the limiting structure 2201 .

[0042] During actual use, due to the elastic force of the elastic part 300, the elastic part 300 fits against the installation position 220, and the two ends of the open ring structure in the length direction respectively abut against the two side surfaces of the limiting structure 2201. In the early stage of elastic contraction of the elastic part 300, it will be restricted by the limiting structure 2201, thereby avoiding the elastic contraction of the elastic part 300 affecting the experience of using the elastic part assembly device.

[0043] Furthermore, limiting slots can be provided on both sides of the limiting structure 2201 for contacting the elastic member 300, and the elastic member 300 can be clamped in the limiting slots to limit the position of the elastic member 300 and prevent the elastic member 300 from sliding along the limiting structure 2201 during elastic contraction, thereby improving the limiting effect of the limiting structure 2201 on the elastic member 300.

[0044] Based on the above embodiments, Figure 3 As shown, the insertion component 210 can include a front end part 2101 and a mounting part 2102, the front end part 2101 is arranged closer to the first plug-in mechanism 100 than the mounting part 2102, the mounting position 220 is arranged on the mounting part 2102, the outer diameter of the front end part 2101 is larger than the outer diameter of the mounting part 2102, and the front end part 2101 can be detachably installed on the mounting part 2102.

[0045] Since the outer diameter of the front end piece 2101 is larger than the outer diameter of the mounting piece 2102, when the front end piece 2101 and the mounting piece 2102 are an integrated structure, when installing the elastic piece 300, it is necessary to first expand the elastic piece 300 so that it passes through the front end piece 2101 and is mounted on the mounting position 220; in the process of expanding the elastic piece 300, the elastic piece 300 will produce a certain deformation, the consistency during the assembly process will deteriorate, and the assembly effect will be affected.

[0046] In this specific embodiment, by detachably connecting the front end part 2101 and the mounting part 2102, the front end part 2101 can be removed first when installing the elastic part 300. When installing the elastic part 300, the elastic part 300 can be avoided from being stretched, and the consistency of the assembly can be effectively guaranteed.

[0047] Specifically, the front end part 2101 can be connected to the mounting part 2102 via a connecting part 230, and the connecting part 230 is arranged along the axial direction of the front end part 2101; the connecting part 230 can be arranged as a connecting bolt or a connecting screw, and the front end part 2101 is provided with a countersunk hole, the connecting part 230 is located in the countersunk hole, and the outer surface of the connecting part 230 is lower than the end face of the countersunk hole in the front end part 2101.

[0048] In a specific embodiment, the mounting position 220 is provided with a mounting hole 2202 and an elastic component 240 disposed in the mounting hole 2202 and retractable in the radial direction. The portion of the elastic component 240 extending out of the mounting hole 2202 abuts against the inner surface of the elastic member 300 .

[0049] The axial direction of the mounting hole 2202 is arranged along the radial direction of the mounting position 220 , and the elastic component 240 is extended and retracted along the axial direction of the mounting hole 2202 , so that the mounting hole 2202 can play a guiding role.

[0050] Specifically, the number of elastic components 240 can be set to multiple, and the multiple elastic components 240 can be evenly distributed along the circumference of the installation position 220. During actual use, different positions of the elastic member 300 can be evenly stressed, thereby improving the effect of avoiding elastic contraction of the elastic member 300.

[0051] On the one hand, the elastic component 240 can include an elastic telescopic structure 2401 and a spherical portion 2402, one end of the elastic telescopic structure 2401 is fixed in the mounting hole 2202, and the other end of the elastic telescopic structure 2401 is connected to the spherical portion 2402; when the elastic member 300 is not installed, the spherical portion 2402 at least partially protrudes from the outer surface of the mounting position 220.

[0052] In actual use, in the initial stage of the elastic member 300 being sleeved on the mounting position 220, the elastic component 240 is in contact with the elastic member 300 or there is a small gap between the elastic component 240 and the elastic member 300. During the elastic contraction of the elastic member 300, the inner surface of the elastic member 300 gradually approaches the elastic component 240 and contacts the elastic component 240. When the elastic component 240 includes the elastic telescopic structure 2401 and the spherical portion 2402, during the elastic contraction of the elastic member 300, the elastic member 300 continuously squeezes the spherical portion 2402, so that the spherical portion 2402 moves in the direction of compressing the elastic telescopic structure 2401. Under the action of the elastic force of the elastic telescopic structure 2401, the spherical part 2402 is affected by the elastic restoring force of the elastic telescopic structure 2401 and transmits the elastic restoring force to the elastic part 300. The elastic telescopic structure 2401 can be set as a spring or other structure that meets the requirements; the elastic part 300 is affected by the elastic restoring force of the elastic telescopic structure 2401, which can effectively avoid the elastic contraction of the elastic part 300. Even if the elastic force of the elastic part 300 decreases, under the support of the elastic component 240, the elastic part 300 can also maintain the required size, thereby avoiding the elastic contraction of the elastic part 300 affecting the experience of using the elastic part assembly device.
