Detailed Implementation

[0033] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] Please see Figures 3-10 As shown, this embodiment provides a welding fixture for a straw bag support, including a base plate 1, which is a square plate. The top of the base plate 1 has multiple weight-reducing holes 102. The design of the weight-reducing holes 102 can reduce the weight of the entire base plate 1, thereby facilitating better transfer. At the same time, it can also recycle waste materials and reduce the material used in the base plate 1.

[0035] The top of the base plate 1 is provided with a plurality of first positioning blocks 2, which are evenly distributed around its perimeter. Each of the first positioning blocks 2 has a first positioning groove 21 on its top. Since the support rod 100 is an open U-shaped structure, the arrangement of the plurality of first positioning blocks 2 around the top of the base plate 1 can adaptably lock the support rod 100 into place.

[0036] The top of the base plate 1 is also provided with two second positioning blocks 3, symmetrically located at the two corners of one of the long sides. Each of the two second positioning blocks 3 has two symmetrical first positioning holes 31 on its adjacent side, through which two first positioning rods 10 are inserted. The first positioning rods 10 are inserted into the second positioning blocks 3, with the insertion end of the first positioning rod 10 extending outwards by a certain length. The connecting plate 200 is then positioned by fitting it onto one end of the first positioning rod 10 through a through hole, thus aligning it with the support rod body 100. Additionally, the nut connected to the connecting plate 200 is also positioned synchronously by fitting it onto the first positioning rod 10.

[0037] The top of the base plate 1 is also provided with four third positioning blocks 4, arranged in a rectangular pattern, and located within the inner section of multiple first positioning blocks 2. Each of the four third positioning blocks 4 has a second positioning groove 41 on its top. After the bracket rod 100 is properly positioned, the two connecting rods 600 are positioned and locked in place through the second positioning grooves 41 on the two third positioning blocks 4, so that both ends of the connecting rods 600 are in contact with the bracket rod 100.

[0038] A fourth positioning block 5 is also provided on one side of the top of the base plate 1. Two second positioning holes 51 are symmetrically opened on the top of the fourth positioning block 5, and two second positioning rods 11 are inserted through the two second positioning holes 51. First, the mounting plate 500 is placed on the top of the fourth positioning block 5, and then the second positioning rods 11 are inserted to position and connect it, so that the two sides of the mounting plate 500 are respectively connected to the two connecting rods 600.

[0039] Two fifth positioning blocks 6 are symmetrically arranged on the top of the base plate 1. Each fifth positioning block 6 has a third positioning hole 62 on its top, through which a third positioning rod 12 is inserted. The top of each fifth positioning block 6 has a nut positioning groove 61 concentrically arranged with the third positioning hole 62. Since a nut is welded onto the cover plate mounting lug 700, when positioning the cover plate mounting lug 700, the nut will face downwards and fit perfectly into the nut positioning groove 61. At this time, the cover plate mounting lug 700 will be completely fitted against the top of the fifth positioning block 6. Inserting the third positioning rod 12 at this point allows it to pass through both the cover plate mounting lug 700 and the nut simultaneously, and then into the third positioning hole 62, completing the positioning connection of the cover plate mounting lug 700 and aligning it with the connecting rod 600. The two fifth positioning blocks 6 each have a chamfered edge 63 on their opposite sides. Since the cover plate mounting lug 700 is L-shaped and its bent part has a certain curvature, by designing an arc chamfer 63, the cover plate mounting lug 700 and the fifth positioning block 6 can fit better, which facilitates more accurate positioning with the connecting rod 600.

[0040] The top of the base plate 1 is also provided with two sixth positioning blocks 7, symmetrically located on the edge of one of the long sides. The top of each of the two sixth positioning blocks 7 is provided with a third positioning groove 71. The rotating shaft 900 is positioned and locked in place through the two third positioning grooves 71. At the same time, the rotating shaft brackets 800 are fitted onto both ends of the rotating shaft 900. Then, the two rotating shaft brackets 800 are inserted and positioned on one side of the sixth positioning block 7 through the two ends of the bracket rod 100, thereby completing the positioning connection between the rotating shaft 900, the rotating shaft brackets 800 and the bracket rod 100.

[0041] The top of the base plate 1 is also provided with two seventh positioning blocks 8, symmetrically located on the edges of the two short sides. Each of the two seventh positioning blocks 8 has a fourth positioning hole 81 on the side closest to each other, through which a fourth positioning rod 13 is inserted. The fourth positioning rod 13 is inserted into the seventh positioning block 8, and the inserted end of the fourth positioning rod 13 extends outward by a certain length. Then, the bracket mounting lug 400 is positioned by fitting it onto the extended end of the fourth positioning rod 13 through the through hole provided thereon, and the bracket mounting lug 400 is aligned with the bracket rod body 100.

[0042] An eighth positioning block 9 is also provided on one side of the top of the base plate 1. Two fifth positioning holes 91 are symmetrically opened on the top of the eighth positioning block 9. Two fifth positioning rods 14 are inserted through the two fifth positioning holes 91 for connecting and positioning the support plate. After the bracket rod 100 and the connecting rod 600 are positioned, the support plate 300 is placed on the top of the eighth positioning block 9 and positioned by inserting the fifth positioning rods 14, so that the support plate 300 is respectively connected to the bracket rod 100 and an adjacent connecting rod 600.

[0043] In one aspect of this embodiment, the bottoms of the first positioning block 2, the second positioning block 3, the third positioning block 4, the fourth positioning block 5, the fifth positioning block 6, the sixth positioning block 7, the seventh positioning block 8, and the eighth positioning block 9 are all integrally provided with a snap-fit ​​portion, and the top of the base plate 1 is provided with a plurality of snap-fit ​​holes 101 for corresponding positioning snap-fit. By designing each positioning block as detachable, the entire fixture can be easily assembled and used, and individual positioning blocks can also be disassembled and replaced, avoiding the scrapping of the entire fixture.

[0044] This invention can be used in the field of welding fixtures for supports on straw bags, and can also be applied to other fields.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
