Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, in order to prevent the relative displacement between the hose 1 and the handle during the use, the fixing structure of the hose 1 of the present invention comprises the hose 1 and the handle connected with the end of the hose 1. Wherein, the handle includes handle upper cover 2 and handle lower cover 3, and handle upper cover 2 closes and can dismantle with handle upper cover 2 lid with handle lower cover 3 and be connected, specifically, all is provided with two fixed columns 4 on the one end inner wall of handle lower cover 3 and handle upper cover 2, is provided with the internal thread in this fixed column 4 for fasteners such as handle upper cover 2 and handle lower cover 3 accessible screws carry out the spiro union. The two fixing columns 4 on the handle lower cover 3 are connected through a first connecting plate; similarly, a first connecting plate is also arranged between the two fixing posts 4 on the handle upper cover 2. The up end of every first connecting plate is provided with the cambered surface, is provided with a plurality of first barbs 5 of laying along the axial of this cambered surface on the cambered surface for prevent that hose 1 from rotating. As shown in figure 3, when the handle upper cover 2 and the handle lower cover 3 are closed, the cambered surfaces of the two first connecting plates form circumferential barb holes, the hose 1 is clamped in the circumferential barb holes, and the first barbs 5 pierce into the outer wall of the hose 1, so that the circumferential fixing effect is exerted on the hose 1, and the rotation of the hose 1 is effectively prevented. Preferably, the cambered surface on the first connecting plate is a semicircular cambered surface.

Further, as shown in fig. 4, a fixing plate 6 is arranged on the inner wall of the handle lower cover 3 close to the fixing column 4, an arc-shaped groove is formed in the position, corresponding to the arc surface of the first connecting plate, of the fixing plate 6, and a plurality of second barbs 7 distributed along the circumferential direction of the arc surface are arranged on the bottom wall of the arc surface of the arc-shaped groove and used for axially fixing the hose 1 to prevent the hose 1 from backing up; when the upper handle cover 2 and the lower handle cover 3 are closed, the hose 1 abuts against the second barb 7. Preferably, the second barb 7 is oriented in a direction away from the first connecting plate and the fixing post 4, so that the anti-retreat effect is further improved.

Furthermore, a positioning frame is arranged on the inner wall of the handle lower cover 3 close to the fixing column 4, the positioning frame is composed of two Contraband-shaped plates 8, each Contraband-shaped plate 8 is composed of a top wall, a side wall and a bottom wall, and the side walls of the two Contraband-shaped plates 8 are arranged oppositely. The width of the gap between the side walls of the two Contraband shaped plates 8 matches the outer diameter of the hose 1, so that the end of the hose 1 is well clamped between the two Contraband shaped plates 8, and further fixing effect is achieved for the hose 1. The side walls of the two Contraband-shaped plates 8 are provided with a plurality of third barbs 9 for preventing the hose 1 from retreating at the positions close to the fixed column 4 and the top wall, and the third barbs 9 are arranged vertically. The hose 1 is arranged in the gap between the two Contraband shaped plates 8 and abuts against the third barb 9. It is further preferred that the third barb 9 is directed towards the bottom wall of the Contraband-shaped plate 8, opposite to the direction of the backward movement of the hose 1, to further prevent the backward movement of the hose 1.

Further, a second connecting plate is provided between the bottom walls of the two Contraband-shaped plates 8, and a U-shaped groove 10 for passing a steering wire, a pipe line, etc. is provided at a position of the second connecting plate corresponding to the gap between the two Contraband-shaped plates 8. Preferably, the width of the U-shaped channel 10 is smaller than the width of the gap, so that the second web forms a positioning protrusion 11 at the junction of the side walls and the bottom wall of the two Contraband-shaped panels 8 for positioning the front end of the hose 1. The end of the hose 1 abuts on the positioning projection 11 so that the front end of the hose 1 is well positioned.

It is seen from the above-mentioned scheme, the utility model discloses a 1 fixed knot of hose constructs can effectively prevent through first barb 5 that hose 1 from rotating, can effectively prevent through second barb 7 and third barb 9 that hose 1 from backing up, can carry out radial positioning and axial positioning to the soft mirror main part respectively through locating rack and location arch 11 to make hose 1 and handle firm in connection, can not take place relative displacement, be favorable to the doctor to observe the state of an illness.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
