Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of the utility model protection.

[0025] Please refer to Figs. 1-4 In the embodiments of the utility model, a yarn guide plate device for air jet loom, including mounting plate 1, mounting hole 2, ceramic yarn guide plate 3, mounting hole 2 is opened in the vertical part front end of mounting plate 1 and penetrates to the rear end of mounting plate 1, mounting hole 2 is used for providing positioning installation space for ceramic yarn guide plate 3, the rear end of mounting plate 1 is provided with quick mounting assembly 4, and quick mounting assembly 4 is used for realizing the clamping locking of ceramic yarn guide plate 3;

[0026] Quick mounting assembly 4 includes locking unit, unlocking unit;

[0027] Locking unit is used for providing locking for the installation of ceramic yarn guide plate 3;

[0028] Unlocking unit is used for unlocking the locking of ceramic yarn guide plate 3 by locking unit, realizing the dismounting operation of ceramic yarn guide plate 3;

[0029] Locking unit includes elastic clamping piece 403;

[0030] Elastic clamping piece 403 is provided with multiple, and multiple elastic clamping pieces 403 are fixed to the rear end of mounting plate 1 with mounting hole 2 as the center annular distribution;

[0031] Ceramic yarn guide plate 3 includes convex ring yarn guide plate 301, annular clamping groove 302, and annular clamping groove 302 is formed on the outside of the rear end of the small diameter part of convex ring yarn guide plate 301;

[0032] Convex ring yarn guide plate 301 is inserted and penetrates mounting hole 2 through the small diameter part, and is clamped in the inside of annular clamping groove 302 through multiple elastic clamping pieces 403, for realizing the relative fixation of convex ring yarn guide plate 301 and mounting plate 1;

[0033] Unlocking unit includes L-shaped fixed cylinder 401, unlocking ring piece 402;

[0034] L-shaped fixed cylinder 401 is fixed to the rear end of mounting plate 1 and is distributed on the outside of mounting hole 2, unlocking ring piece 402 is limitingly and slidingly connected to the outside of L-shaped fixed cylinder 401, and L-shaped fixed cylinder 401 and unlocking ring piece 402 are distributed on the inside of multiple elastic clamping pieces 403, the inclined part of multiple elastic clamping pieces 403 is extruded by the horizontal movement of unlocking ring piece 402 to make multiple elastic clamping pieces 403 deform and expand, for realizing the unlocking operation of convex ring yarn guide plate 301;

[0035] The inner diameter of the mounting hole 2 and the unlocking ring 402 matches the outer diameter of the small diameter part of the convex ring guide plate 301.

[0036] In this embodiment: it needs to be added that the mounting plate 1 is fixed on the air-jet loom at the position where the yarn needs to be guided;

[0037] The ceramic guide plate 3 is a whole side-up "convex" ring structure. When installing the ceramic guide plate 3, only the small diameter part of the convex ring guide plate 301 needs to be aligned with the mounting hole 2 at the front end of the mounting plate 1 and inserted. The small diameter part of the convex ring guide plate 301 penetrates the mounting hole 2, the L-shaped fixed cylinder 401, and contacts and extrudes the plurality of elastic clamping pieces 403. The plurality of elastic clamping pieces 403 are deformed and expanded outward under the extrusion force, and then the rear end of the small diameter part of the convex ring guide plate 301 smoothly passes through the middle of the plurality of elastic clamping pieces 403. When the annular clamping groove 302 contacts the elastic clamping piece 403, the elastic clamping piece 403 resets and clamps into the annular clamping groove 302 under the action of its own elastic force, that is, the installation and fixation of the ceramic guide plate 3 are completed.

[0038] When the ceramic guide plate 3 needs to be disassembled, only the unlocking ring 402 needs to be pulled manually to extrude the elastic clamping piece 403 on the outside of the unlocking ring 402, so that the plurality of elastic clamping pieces 403 are deformed and expanded and separated from the annular clamping groove 302. At this time, the ceramic guide plate 3 can be pushed forward, and the disassembly operation is completed.

[0039] Please refer to Figs. 1-4 The end face of the large diameter part of the convex ring guide plate 301 close to the mounting plate 1 is formed with an annular groove 303, and the annular groove 303 is installed with a rubber ring 5 inside, and the rubber ring 5 is attached to the end face of the mounting plate 1.

[0040] In this embodiment: when the ceramic guide plate 3 is installed, the large diameter part of the convex ring guide plate 301 is separated from the end face of the mounting plate 1 by the rubber ring 5, and the rubber ring 5 keeps the installation state of the ceramic guide plate 3 stable;

[0041] At the same time, when the elastic clamping piece 403 is extruded and unlocked by pulling the unlocking ring 402, the elastic clamping piece 403 will generate a backward extrusion force on the ceramic guide plate 3. This extrusion force is transmitted to the rubber ring 5 to make it shrink. In this way, the ceramic guide plate 3 can be slightly moved a small distance to the rear end, thereby providing space for the deformation of the elastic clamping piece 403 and ensuring the stable operation of the elastic clamping piece 403 moving out of the annular clamping groove 302.

[0042] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
