DETAILED DESCRIPTION

[0028] The utility model will be further explained in connection with the drawings as follows:

[0029] The orientation terms involved in the paragraphs of detailed description are only for the convenience of the person skilled in the art to understand the technical solutions recorded in the application according to the visual orientation shown in the drawings. Except for explicit provisions and limitations, the terms such as "setting", "installing", "connecting" should be understood broadly, and for the person skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0030] Example one:

[0031] As Figures 1 to 7As shown, a folding hinge includes a center shaft 1 for supporting the rotation of other components and serving as the rotation center of the entire folding hinge. The center shaft 1 is rotationally connected with one or more sets of hinge mechanisms. In this embodiment, the hinge mechanisms are preferably two sets, which are rotationally connected with both ends of the center shaft 1 and symmetrically arranged. The two sets of hinge mechanisms enhance the stability and load-bearing capacity of the folding hinge, and the symmetric arrangement of the two sets of hinge mechanisms enables the hinge to more evenly distribute the external force when it is subjected to the external force, avoiding the situation of excessive local stress.

[0032] Specifically, each set of hinge mechanisms includes two hinge bodies 2 arranged symmetrically, which are identical in structure and symmetrically arranged, and functionally cooperate with each other during use to achieve the rapid folding and unfolding of the hinge through coordinated action.

[0033] During manufacturing, the hinge body 2 has a U-shaped structure, and the side away from the end of each hinge body 2 in the same set of hinge mechanisms is rotationally connected with the center shaft 1, so that the hinge body 2 can flexibly rotate around the center shaft 1. The side close to the end of each hinge body 2 is provided with a fixed plate 3, and the fixed plate 3 is provided with a mounting hole one 301 and a mounting hole two 302. The fixed plate 3 plays a key role in connecting and limiting the hinge body 2, and provides a stable basis for the connection between the hinge and the cutting table. When the folding hinge is unfolded, the two fixed plates 3 are arranged in the same horizontal plane and can be tightly fitted. The end away from the other end of each hinge body 2 is provided with a sliding groove 204, and a sliding shaft 5 is slidably connected in the sliding groove 204. The sliding shaft 5 can flexibly slide in the sliding groove 204; the sliding shaft 5 is fixedly connected with the mounting hole one 301 on the fixed plate 3 close to it, i.e., the fixed plate 3 is located directly below the hinge body 2 where the sliding shaft 5 is located; the other end of the hinge body 2, i.e., the end close to the other end of the two hinge bodies 2, is rotationally connected with the mounting hole two 302 of the other fixed plate 3 through a rotating shaft 6, and the fixed plate 3 is adjacent to the previous fixed plate 3, i.e., the fixed plate 3 and the previous fixed plate 3 are not the same component. This structure design enables smooth relative movement between components during folding and unfolding of the hinge, ensuring the stability of the connection and realizing the flexible folding function.

[0034] For example, Figure 6As shown, the hinge body 2 includes a rotating plate 201. A central hole 202, which mates with the central shaft 1, is provided on the rotating plate 201. The central hole 202 is offset from the center of the rotating plate 201. One end of the rotating plate 201 has a side plate 203, and a sliding groove 204 is located at the end of the side plate 203 away from the rotating plate 201. This arrangement allows the sliding shaft 5 to slide in a suitable position, assisting the hinge in achieving folding angles exceeding 180°. The other end of the rotating plate 201 has a second side plate 205, with a rotating hole 206 near its end that mates with the rotating shaft 6, ensuring smooth rotational connection between the hinge body 2 and the fixed plate 3.

[0035] It is important to note that the length of side panel 1 203 is greater than the length of side panel 205. An angle b is formed between the inner side of side panel 1 203 and the rotating plate 201, while an angle c is formed between side panel 205 and the rotating plate 201. Angle b is 60-100°, a range that provides sufficient support and stability to side panel 1 203 during hinge folding, while also ensuring the flatness of the hinge when unfolded. Angle c, also 60-100°, allows side panel 205 to maintain hinge folding flexibility while cooperating with side panel 1 203 to achieve the hinge folding action. An angle α, 30-60°, is formed between the central axis of the slide groove 204 and the inner side of side panel 1 203. This angle optimizes the sliding trajectory of the sliding shaft 5, making the hinge move more smoothly. By rationally designing the hinge body 2, the folding hinge can achieve a folding effect of more than 180°, thus ensuring the effective folding of the multi-section workbench 9.

[0036] In this embodiment, to further improve the stability and load-bearing capacity of the folding hinge, a long rib plate 8 is fixedly connected between the outer hinge bodies 2 of the two hinge mechanisms, and a short rib plate 7 is fixedly connected between the inner hinge bodies 2. Limiting holes 207 for mounting the long rib plate 8 and the short rib plate 7 are provided on the hinge bodies 2. The long rib plate 8 and the short rib plate 7, acting like reinforcing ribs, greatly enhance the overall strength and rigidity of the hinge, enabling it to better adapt to the various forces exerted on the cutting workbench during operation.

[0037] During installation, the mounting plate 4 is fixedly connected to the side of the fixing plate 3 away from the hinge mechanism. The mounting plate 4 facilitates the installation of the folding hinge and the cutting workbench. Through the mounting plate 4, the folding hinge can be firmly installed on the adjacent workbench plate 9, ensuring that the folding hinge will not loosen or shift during operation.

[0038] Example 2:

[0039] like Figures 8 to 10As shown, a folding portable cutting table comprises two or more workbench plates 9, and at least one folding hinge as described in embodiment one is arranged between adjacent workbench plates 9. Preferably, two folding hinges are arranged between adjacent workbench plates 9 for higher stability. The two ends of the hinge mechanism are fixedly connected to adjacent workbench plates 9 through mounting plates 4. To ensure folding effect, users can adjust the size of the folding hinge according to needs.

[0040] After the cutting table is folded, a plurality of mobile wheels 10 for transportation can be installed on the bottom workbench plate 9 for easy transportation of the cutting table.

[0041] In use, the telescopic supporting legs, track saw, guide rail and other components can be placed on the upper part of the folded cutting table. The cutting table is connected to a pull rope or a pull rod on one side, and the cutting table can be directly pulled and moved through the pull rope or the pull rod, so that the cutting table and the cutting components can be easily and conveniently transported.

[0042] The telescopic supporting legs are preferably spider-type telescopic legs. In installation, the spider-type telescopic legs are first unfolded, and then the workbench plates 9 are flipped outward to unfold all the workbench plates 9 into a plane, as shown. Figure 9 Then, the unfolded workbench plates 9 can be placed on the spider-type telescopic legs. To improve the stability of the cutting table, the upper support plate of the spider-type telescopic legs is located between adjacent workbench plates 9, i.e., the support plate and the adjacent workbench plates 9 are in contact, so as to avoid local folding of the cutting table due to stress during work.

[0043] Finally, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. The description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
