[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Example 1

[0030] See also Figure 1-Figure 14 A pan head connection structure includes a first connecting member 1 and an intermediate member 2 assembled on the first connecting member 1, wherein the first connecting member 1 is used to be installed on one end of a pan head 3, and the overall outer end after the first connecting member 1 and the intermediate member 2 are assembled is used to cooperate with the second connecting member 4, and the overall outer end is locked by the second connecting member 4, and the second connecting member 4 is installed on the end of another pan head to realize the connection between two adjacent pan heads.

[0031] As one embodiment, for multiple pan heads of the same power source, one end of the first pan head is connected to the power source by transmission, and the other end is provided with a first connecting piece 1 and an intermediate piece 2 as a whole; one end of the second pan head is provided with a second connecting piece 4 for connecting to the first pan head, and the other end is also provided with a first connecting piece 1 and an intermediate piece 2 as a whole; the last pan head only needs to be provided with a second connecting piece 4 at one end to connect with the adjacent pan head. The specific number of pan heads is selected according to actual needs and the driving force of the corresponding power source.

[0032] The intermediate member 2 includes an inner ring 21, an outer ring 22, and a plurality of spokes 23 arranged between the inner ring 21 and the outer ring 22. Figure 1-3 shown.

[0033] The shape of the inner ring 21 can be various. In the present embodiment, the shape of the inner ring 21 is circular, and an extension portion 211 is formed by axial extension on its inner end surface. The outer diameter of the extension portion 211 is smaller than the outer diameter of the main body portion of the inner ring. A through hole 212 (including the extension portion) is provided on the inner ring 21 for the fastener to pass through. The through hole 212 includes a first hole 2121 for cooperating with the fastener stem and a second hole 2122 for cooperating with the fastener head. The second hole 2122 is arranged at the outer end of the inner ring 21. The aperture of the second hole 2122 is larger than the aperture of the first hole 2121, and the two are connected to each other.

[0034] As one of the options for the outer ring 22, its outer wall shape is circular and the overall shape is annular. In this embodiment, the inner ring 21 is arranged relatively outward in the axial direction so that the spokes 23 connected thereto are also arranged outward, thereby forming a space on one side of the inner end of the outer ring 22 for avoiding the corresponding parts on the first connecting member 1, so that the intermediate member 2 is reliably connected to the first connecting member 1.

[0035] The first connecting member 1 includes a middle area 11 for accommodating at least part of the inner ring 21 and a plurality of grooves 12 for accommodating the spokes 23. The grooves 12 are in fluid communication with the middle area 11. The number of the grooves 12 corresponds to the number of the spokes 23. The specific number can be selected according to the needs, such as six grooves are evenly arranged in the circumferential direction. Figure 4 As shown, it can also be understood that there are multiple blocks such as Figure 4 The protrusions of the shown style form a groove 12 for accommodating the spokes 23 between two adjacent protrusions, and form a middle area 11 for accommodating at least part of the inner ring 21 in the area not reached by the front end of the protrusion.

[0036] In this embodiment, the middle area 11 includes an inner groove 111 for cooperating with the extension portion 211 of the inner ring 21 to improve the assembly effect between the intermediate member 2 and the first connecting member 1. As one implementation method, the shape of the inner groove 111 and the shape of the extension portion 211 can both be circular.

[0037] In this embodiment, as a preference, the entire material of the middle piece 2 is a deformable material, such as spring steel. Of course, only some parts of the middle piece 2 may be made of spring steel, which will actually be worse than the form where the entire material is spring steel.

[0038] In this embodiment, the intermediate member 2 is axially positioned on the first connecting member 1 by a fastener provided at the through hole, such as Fig. 9 After several disk heads are connected through the above structure and the power source is started, the middle piece 2 needs to have space for movement in the radial direction, combined with the characteristics of its deformable material, to help the self-alignment of the center points between the multiple disk heads. Specifically, a gap is left between the outer wall of the middle area 11 and the outer wall of the inner ring 21 and / or between the side wall of the groove body 12 and the side wall of the spoke 23. The gap does not need to be too large, and only needs to be able to provide space for the middle piece 2 to move.

[0039] As one of the implementation modes, a gap is also left between the inner groove 111 and the extension portion 211 , and the extension portion 211 , the inner ring 21 and the outer ring 22 are all concentrically arranged.

[0040] like Figure 8 , Fig.12 , Fig.13 As shown, the shaft portion of the inner end of the first connecting member 1 is inserted into the flange 31 of the pan head 3, specifically inserted from the outer end of the flange 31, and then the first connecting member 1 is positioned as a whole at the outer end of the flange 31 by a fastener or a pin.

[0041] The middle piece 2 is specifically assembled on the outer end of the first connecting piece 1 , and the component matched with the second connecting piece 4 is a combination of the middle piece 2 and the outer end of the first connecting piece 1 .

[0042] As one embodiment, the outer wall of the outer end of the first connecting member 1 and the inner and outer walls of the outer ring 22 are all circular, and the cavity 43 on the second connecting member 4 that matches therewith is also circular.

[0043] For the second connecting member 4, if Fig.10 , Fig.11 , Fig.14 As shown, it includes a first portion 41 and a second portion 42 assembled on the first portion 41, wherein the shaft portion at the inner end of the first portion 41 is passed through the flange 31 of the pan head 3, specifically inserted from the outer end of the flange 31, and then the second connecting member 4 is positioned as a whole at the outer end of the flange 31 through a fastener or a pin shaft.

[0044] The first portion 41 has a semicircular convex portion 411 at its outer end, and the second portion 42 is a semicircular component matched with the semicircular convex portion 411. Fig.10 As shown, the circular cavity 43 formed after assembly is used to accommodate the integral component after the middle piece 2 and the outer end of the first connecting piece 1 are combined, and the second portion 42 can be locked by a fastener penetrated thereon.

[0045] After the overall component after the middle piece 2 and the outer end of the first connecting piece 1 are assembled in the cavity 43, it can be locked by the fasteners penetrated on the second part 42. Although it is locked, relying on the deformability of the spring steel material and the designed gap layout, when the power source is driven, the disk head can self-align the center point to prevent the power source from being damaged due to excessive load on the power source caused by the misalignment of the center point, affecting the synchronous wire feeding, the wear and damage of the connection parts between adjacent disk heads, and the inability to transmit power to the rear disks. Example 2

[0046] Compared with the first embodiment, the difference is that at least a part of at least one of the first connecting member 1, the intermediate member 2 and the second connecting member 4 is made of a deformable material, such as spring steel. The rest of the structure is consistent with the first embodiment.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
