Detailed Description

The adjustable wire feeding frame of the present invention is further described with reference to fig. 1 to 3.

The utility model provides an adjustable wire rod pay-off frame, characterized by: comprising a chassis 1 and a coil former 2. The base 1 comprises a frame body 11, a vertical column 12, a lower sleeve 14 and a first support rod 13; the upright post 12 is vertically and integrally formed on the frame body 11 and is provided with a threaded section, and an adjusting pipe 121 is in threaded fit with the threaded section; the frame body 11 comprises a central block 111 and four supporting legs 112 which are uniformly hinged around the central block 111 through pin shafts; the lower sleeve 14 is axially movably sleeved on the upright post 12 and is positioned below the adjusting pipe 14; the number of the first supporting rods 13 corresponds to the number of the supporting feet 112, the upper ends of the first supporting rods 13 are hinged on the lower sleeve, and the lower ends are hinged on the supporting feet 112. The bobbin 2 includes an upper sleeve 24, an intermediate sleeve 21, a second support bar 22, and a third support bar 23; the upper end of the upper sleeve 24 is closed, and the lower end is opened and is sleeved on the top end of the upright post 12; the number of the second support rods 22 is four, the four second support rods 22 are uniformly arranged in a circumferential manner by taking the upright post 12 as a circle center, and the upper end of each second support rod 22 is hinged to the upper sleeve 24; the middle sleeve 21 is axially movably sleeved on the upright post 12 and is positioned between the adjusting pipe 121 and the lower sleeve 14; the number of the third support rods 23 corresponds to the number of the second support rods 22, the upper end of each third support rod 23 is hinged to the middle sleeve 21, and the lower end of each third support rod 23 is hinged to the lower end of the second support rod 22.

Based on the above structure, when the wire frame is folded, the middle sleeve 21, the adjusting tube 121 and the lower sleeve 14 all move upwards, so that the third support rod 23 drives the second support rod 22 to fold towards the upright post 12, and simultaneously the first support rod 13 drives the outer end of the support leg 112 to fold towards the upright post 12, thereby facilitating the storage and transportation of the whole wire frame; when the wire coil support is needed to be used, the middle sleeve 21, the adjusting pipe 121 and the lower sleeve 14 are moved downwards, so that the lower ends of the second supporting rod 22 and the third supporting rod 23 are expanded outwards to support the wire coil 2, and meanwhile, the first supporting rod 13 drives the supporting legs 112 to be expanded, so that the base 1 can be stably supported on the ground. In the above process, the adjusting pipe 121 is in threaded fit with the threaded section, so that the adjusting pipe can be axially limited in a natural state. In operation, the upper end of the intermediate sleeve 21 abuts the lower end of the adjustment tube 121 and the upper end of the lower sleeve 14 is supported at the lower end of the intermediate sleeve 21. The upper sleeve 24 and the intermediate sleeve 21 are circumferentially rotatable on the upright 12. In the present embodiment, the diameter of the bobbin is gradually increased from the collapsed state to the expanded state, so that the wire loops 2 having different diameters can be accommodated.

A plane bearing 3 is arranged between the adjusting pipe 121 and the middle sleeve 21. The flat bearing 3 can facilitate the rotation of the adjustment tube 121 when the intermediate sleeve 21 is supported at the lower end of the adjustment tube 121.

The lower end of the third support bar 23 has a bending part 231 bent upward. The bending part 231 can support the wire coil 2, and the stability of the wire coil 2 in the invention is improved.

The second support bar 22 has a fork 221 at a lower end thereof, a hinge pin 222 is disposed in the fork 221, and the second support bar 22 is hinged to the third support bar 23 through the fork 221 and the hinge pin 22.

The upper casing 24, the middle casing 21 and the lower casing 14 each have an

articulation seat

241, 21, 1141 thereon. The hinged base is composed of two positioning plates and a rotating shaft arranged between the two positioning plates, and the upper ends of the first supporting rod 13, the second supporting rod 22 and the third supporting rod 23 are hinged to the

hinged bases

241, 21 and 1141 through hinged holes in the upper ends of the first supporting rod, the second supporting rod and the third supporting rod.

The supporting leg 112 has an opening 1121, the opening 1121 has a hinge pin 1122 therein, and the lower end of the first supporting rod 13 is hinged to the hinge pin 1122.
