[0004] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0005] The utility model discloses a rapid measuring and positioning device for a large circular knitting machine, comprising a column, a lifting groove is provided inside the column, an adjusting threaded rod is rotatably connected to the inner bottom wall of the lifting groove, a twisting cap is fixedly connected to the top of the adjusting threaded rod, an anti-falling bracket is fixedly connected to the bottom of the column, a lifting disk is sleeved inside the column, a rotating mechanism is arranged outside the lifting disk, a fixing block is fixedly connected to the edge of the upper surface of the rotating mechanism, a sliding rod is fixedly connected to the top of the fixing block, an end of the sliding rod close to the column is fixedly connected to an anti-dropping cap, an end of the sliding rod away from the anti-dropping cap is fixedly connected to a supporting plate, a side of the supporting plate close to the anti-dropping cap is fixedly connected to a ruler, and a measuring mechanism is slidably connected to the surface of the sliding rod.

[0006] As a further improvement of the above solution, the twist cap is rotatably connected to the top of the column, and the fixed block, the slide rod, the anti-drop cap and the support plate are symmetrically distributed on the upper surface of the rotating mechanism with the column as the axis.

[0007] As a further improvement of the above scheme, a limiting groove is provided on the surface of the lifting plate, and the limiting groove is symmetrically distributed up and down with the lifting plate as the axis, and the cross-section of the limiting groove is L-shaped. The lifting plate is slidingly connected to the inner wall of the lifting groove, the center of the lifting plate is penetrated by the adjusting threaded rod, and the lifting plate and the adjusting threaded rod are meshingly rotatably connected.

[0008] As a further improvement of the above solution, the rotating mechanism includes a fixed ring, a positioning block is fixedly connected to the inner wall of the fixed ring, the positioning blocks are symmetrically distributed up and down on the inner wall of the fixed ring, and rollers are rotatably connected between the positioning blocks.

[0009] As a further improvement of the above scheme, a connecting plate is fixedly connected to the surface of the positioning block, and a clamping block is fixedly connected to one end of the connecting plate away from the inner wall of the fixing ring. The end of the clamping block is provided with a certain curvature, and the curvature is the same as that of the circumferential surface of the lifting plate, and the clamping block and the limiting groove are matched and buckled with each other.

[0010] As a further improvement of the above solution, the measuring mechanism includes a pointer blade, which is in contact with the upper surface of the ruler, and a pressure plate is fixedly connected to one end of the measuring mechanism away from the pointer blade.

[0011] As a further improvement of the above solution, a fixing bolt is rotatably connected inside the top of the pressure plate, and the fixing bolt passes through the surface of the slide rod from the top of the fixing bolt and is in contact with the surface of the slide rod.

[0012] The utility model has the following beneficial effects:

[0013] 1. This kind of quick measurement and positioning device for circular knitting machines places the column inside the circular knitting machine and places the anti-fall bracket on the ground, so that the column will not fall over easily. Then, the positioning measurement is performed according to the device that needs to be measured and positioned on the circular knitting machine. Specifically, the twist cap is first rotated to make the twist cap drive the adjusting threaded rod to rotate, so that the lifting plate that engages and rotates on the surface of the adjusting threaded rod can move up or down along the surface of the adjusting threaded rod. Here, it is adjusted automatically according to the positioning height of the device to be measured on the circular knitting machine, avoiding the problem of single measurement height of traditional positioning measurement devices, thereby improving the flexibility and efficiency of measurement.

[0014] 2. The rapid measuring and positioning device for the circular knitting machine stops rotating the twist cap after the height adjustment is completed, so that the lifting plate keeps the height unchanged, and then the measurement and positioning are completed according to the position of the device to be measured on the circular knitting machine by using the cooperation of the slide bar, the ruler and the measuring mechanism. Specifically, first ensure that the ruler can completely cover the upper part of the two groups of devices to be measured on the circular knitting machine, and abut the pressure plate of one group of measuring mechanisms against the vertical surface of the device to be measured on the circular knitting machine, and then fix the fixing bolts so that the measuring mechanism will not slide on the slide bar, and then repeat the above operation for the other group of measuring mechanisms. After the two groups of measuring mechanisms are fixed, the two groups of ruler values ​​can be read by using the cooperation of the pointer cutter head and the ruler, and then the two groups of values ​​are added to obtain the straight-line distance of the device to be measured on the circular knitting machine. Since the rotating mechanism is set, when one group of values ​​is measured, if another pair of devices to be measured needs to be measured at this time, the rotating mechanism can be directly rotated to achieve the measurement and positioning of the other two groups of devices to be measured, without moving the column, so that the measurement efficiency is greatly improved.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
