Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Such as Figure 1-10 As shown, it is a four-way bending mechanism; the endoscope bending mechanism includes a main frame 1, a braided mesh and a rubber coating 2, and a traction wire 3. The main frame 1 is covered with a layer of braided mesh and rubber coating 2, and the main frame 1 is pierced and connected with several pulling wires 3 to form a rivet-free endoscope bending mechanism as a whole.

[0025] Among them, the main body frame 1 is composed of several connecting rings cut from a thin-walled circular tube. The connecting rings include front-end rings 4 at both ends, rear-end rings 6 and several extension rings 5 ​​in the middle; The hole 7, the right end of the front end ring 4 distributes two circular connecting ears 8 symmetrically along the radial direction, the right end surface of the front end ring 4 has a joint surface 9 that fo...

Abstract

The invention discloses an endoscope bending mechanism free of rivet connection. The mechanism comprises a main frame (1), a net, laminated rubber (2) and pull wires (3), wherein the main frame (1) is wrapped in the net and the laminated rubber (2), the multiple pull wires (3) are arranged in the main frame (1) in a penetrating mode, and then the endoscope bending mechanism free of rivet connection is formed. A round connecting lug on a connecting ring is connected with an incomplete round hole of an adjacent connecting ring to form a rotary pair, each connecting ring is formed by cutting a thin-walled round tube, connecting lug punching and riveting assembly adopted in the traditional connecting method are omitted, rotation is flexible, size precision and matching precision are high, designing, machining and assembly are convenient, and remarkable effect is realized during manufacturing of small-pipe-diameter and multi-bending-direction bending mechanisms.

Description

technical field [0001] The invention relates to an endoscope bending mechanism connected without rivets, belonging to the technical field of medical / industrial endoscopes. Background technique [0002] At present, the bending mechanism of the endoscope detection end is composed of bending coupling rings, rivets, traction wires, braided nets, and rubber coatings. The coupling rings are connected by rivets, and the adjacent joints are relative to each other around the rivet axis under the control of the traction wires. turn. Due to the large number of joints and small structural size, a large number of molds and fixtures are required for processing and assembly, and the process is complicated. It is difficult to manufacture a high-precision bending mechanism at a low cost. Contents of the invention [0003] The object of the present invention is to provide an endoscope bending mechanism without rivet connection, which eliminates the stamping and riveting assembly work of th...
