The utility model discloses a further set up to: one end fixed connection of flexure strip is kept away from the one end lateral wall of yarn frame body at the mounting groove, the flexure strip does not contact with the tank bottom of mounting groove.

The utility model discloses a further set up to: the yarn holder is characterized in that one end, far away from the yarn holder body, of the yarn rod is provided with a threaded end, and the threaded end is connected with a limiting end cover used for preventing the yarn barrel from falling off from the yarn rod in a threaded mode.

The utility model discloses a further set up to: a yarn penetrating rod is arranged above the yarn frame body, and yarn penetrating holes for a plurality of yarns to penetrate through are formed in the yarn penetrating rod.

The utility model discloses a further set up to: and a ceramic sleeve is arranged in the yarn penetrating hole, and round corners are formed at the edges of the inner ring of the two end faces of the ceramic sleeve.

To sum up, the utility model discloses following beneficial effect has: the yarn pole rotates to be connected and can realize driving a yarn section of thick bamboo and rotate on the yarn frame body, and when establishing a yarn section of thick bamboo cover on the yarn pole, the elasticity portion on the flexure strip in the mounting groove receives the extrusion back elasticity of the inner wall of a yarn section of thick bamboo and supports tightly on the inner wall of a yarn section of thick bamboo to can realize contradicting the yarn section of thick bamboo of different internal diameters, finally have the effect that reduces the rocking degree on the yarn pole of the yarn section of thick bamboo cover of different internal diameters.

Detailed Description

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

Example 1: a yarn frame, as shown in figure 1, comprises a yarn frame body 1 and a plurality of yarn rods 2 distributed in an array on the yarn frame body 1.

As shown in fig. 1 and 2, one end of the yarn bar 2 is rotatably connected to the yarn stand body 1 via a bearing (not shown). The periphery of the yarn rod 2 is provided with an elastic pressing component 3 which is used for tightly abutting against the inner walls of the yarn cylinders with different inner diameters. A plurality of mounting grooves 21 are formed on the peripheral side of the yarn bar 2, distributed in a circumferential array, and extend in the longitudinal direction of the yarn bar 2. The elastic pressing member 3 includes a plurality of elastic pieces 31 which are respectively disposed in the mounting grooves 21 and extend in a wave shape. One end of the elastic sheet 31 is fixedly connected to the side wall of one end of the mounting groove 21 far away from the yarn frame body 1; the elastic sheet 31 is not contacted with the bottom of the mounting groove 21; meanwhile, a plurality of elastic parts 311 which respectively protrude out of the mounting groove 21 and are used for abutting against the inner walls of the yarn cylinders with different inner diameters are formed on the elastic piece 31.

As shown in fig. 1 and 2, a threaded end 22 is provided at an end of the yarn bar 2 away from the yarn stand body 1, and a limit end cap 4 for preventing the yarn bobbin from falling off from the yarn bar 2 is screwed to the threaded end 22.

As shown in fig. 1 and 3, a yarn threading rod 5 is fixedly arranged above the yarn stand body 1, and a plurality of yarn threading holes 51 through which yarns can pass are arranged on the yarn threading rod 5. Meanwhile, a ceramic sleeve 6 is fixedly arranged in the yarn threading hole 51, and fillets 61 are formed at the edges of the inner ring of two end faces of the ceramic sleeve 6.

The implementation principle is as follows: the yarn rod 2 is rotatably connected to the yarn frame body 1 to drive the yarn barrel to rotate, when the yarn barrel is sleeved on the yarn rod 2, the elastic part 311 on the elastic piece 31 in the mounting groove 21 is elastically abutted to the inner wall of the yarn barrel after being extruded by the inner wall of the yarn barrel, so that the yarn barrels with different inner diameters can be abutted, and the effect of reducing the shaking degree of the yarn barrel with different inner diameters sleeved on the yarn rod 2 is finally realized.

The yarn through hole 51 on the yarn rod 2 on the yarn frame body 1 can be used for the yarn on the yarn cylinder to pass through, thereby avoiding the winding among the yarns; meanwhile, the ceramic sleeve 6 in the yarn penetrating hole 51 can reduce the friction force between the ceramic sleeve and the yarn, and the abrasion of the yarn is reduced.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
