[0024] Please refer to Figure 1-6 , an embodiment provided by the present invention:

[0025] A clamping device for cooling in pipe fitting production, comprising: a first fixture 1, a second fixture 2 and a limiting structure 3;

[0026] Inside the first connecting piece 103 of the first fixture 1, a first rotating shaft 104 is connected by bolts. The lower end of the first connecting piece 103 is welded with a second connecting rod 105, and the lower end of the second connecting rod 105 is welded with a first arc-shaped clamp 106. The inner side of the first arc-shaped clamp 106 is welded with a first friction layer. The outside of the first fixture 1 is connected to the second fixture 2 by the limiting structure 3. The lower end of the second arc-shaped clamp 207 in the second fixture 2 is threaded and hollowed to form a first threaded groove 209. The upper and lower ends of the first threaded groove 209 are threaded and hollowed to form a second threaded groove 210. A screw rod 212 is rotatably connected inside the first threaded groove 209. One side of the first clip 301 in the limiting structure 3 is threaded and hollowed to form a third threaded groove 302. A first rotating bolt 303 is threadedly connected inside the third threaded groove 302. The lower end of the first rotating bolt 303 is hollowed to form a first jack 304. One side of the second clip 305 in the limiting structure 3 is welded with a sliding groove 308. A slider 309 is movably connected inside the sliding groove 308. The lower end of the slider 309 is welded with an inserting rod 310.

[0027] Furthermore, the lower end of the first handle 101 in the first fixture 1 is welded with a first connecting rod 102, and the lower end of the first connecting rod 102 is welded with the upper end of the first connecting piece 103. The first rotating shaft 104 connected by bolts inside the first connecting piece 103 is used to rotate the first connecting rod 102 and the second connecting rod 105.

[0028] Furthermore, the first friction layer 107 welded on the inner side of the first arc-shaped clamp 106 is used to make the pipe more stable when being clamped.

[0029] Further, a third connecting rod 202 is welded to the lower end of the second handle 201 in the second fixture 2. The lower end of the third connecting rod 202 is welded to the upper end of the second connecting piece 203. A second rotating shaft 204 is connected to the inside of the second connecting piece 203 by bolts. A fourth connecting rod 205 is welded to the lower end of the second connecting piece 203. A grip 206 is welded to the lower end of the fourth connecting rod 205. The second rotating shaft 204 connected to the inside of the second connecting piece 203 by bolts is used to rotate the third connecting rod 202 and the fourth connecting rod 205. The grip 206 is used to enable the staff to support the fourth connecting rod 205 when the arc-shaped pipe is lifted, so that the arc-shaped pipe will not fall.

[0030] Further, a second arc-shaped clamp 207 is welded to the lower end of the grip 206. A second friction layer 208 is welded to the inner side of the second arc-shaped clamp 207. A limiting rod 211 is welded to the upper end of the screw 212. The first thread groove 209 and the second thread groove 210 are used to rotatably connect the screw 212. The limiting rod 211 welded to the upper end of the screw 212 is used to further assist in supporting the pipe.

[0031] Further, a third thread groove 302 is welded to the upper end of the first clamp 301 in the limiting structure 3. A first rotating bolt 303 is rotatably connected to the inside of the third thread groove 302. The lower end of the first rotating bolt 303 is hollowed out to form a first insertion hole 304. A fourth thread groove 306 protrudes from one side of the second clamp 305 rotatably connected to one side of the first rotating bolt 303. The upper end of the fourth thread groove 306 is hollowed out to form a second insertion hole 307. The third thread groove 302 welded to the upper end of the first clamp 301 is used to rotatably connect the first rotating bolt 303. The first insertion hole 304 hollowed out at the lower end of the first rotating bolt 303 is used to insert the insertion rod 310.

[0032] Further, a sliding groove 308 is welded to one side of the second clamp 305. A slider 309 is movably connected to the inside of the sliding groove 308. An insertion rod 310 is welded to the lower end of the slider 309. A second rotating bolt is rotatably connected to the threaded hollow part at the upper end of the slider 309. The sliding groove 308 is used to slidably connect the slider 309. The second rotating bolt rotatably connected to the upper end of the slider 309 is used to frictionally fix the slider 309 in the sliding groove 308.

[0033] Working principle: When it is necessary to clamp a straight pipe, one can hold the first handle 101 and the second handle 201 with the hand and press inward, so that the first rotating shaft 104 and the second rotating shaft 204 rotate the second connecting rod 105 and the fourth connecting rod 205. When the second connecting rod 105 and the fourth connecting rod 205 rotate, they drive the first arc-shaped clamp 106 and the second arc-shaped clamp 207 to clamp inward. When the first arc-shaped clamp 106 and the second arc-shaped clamp 207 clamp inward, the first friction layer 107 and the second friction layer 208 will fit on both sides of the pipe so that the pipe will not fall off easily, and then the pipe can be picked up, placed and transported. When it is necessary to transport an arc-shaped pipe, due to the curved surface of the arc-shaped pipe, it is easy to drop when clamping the arc-shaped pipe. One can rotate the second rotating bolt 311 so that the second rotating bolt 311 rotates upward from the slider 309, causing the slider 309 to slide in the chute 308, so that the insertion rod 310 is pulled out of the second jack 307. Then rotate the first rotating bolt 303 so that the first rotating bolt 303 rotates out of the first clip 301 and the second clip 305. Then rotate the screw rod 212 so that the screw rod 212 rotates out of the first thread groove 209 and rotates and connects to the second thread groove 210. Hold the second handle 201 and insert the second arc-shaped clamp 207 into the interior of the arc-shaped pipe and hook one end of the arc-shaped pipe with the limiting rod 211, then the pipe can be transported. When the transported pipe is heavy, one can hold the grip 206 with the hand for auxiliary support, and that's it.

[0034] The above is only the preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention; any ordinary technician in this industry can smoothly implement the present invention according to the illustrations in the specification and the above description; however, any slight changes, modifications and equivalent variations made by those skilled in this professional field without departing from the technical solution of the present invention, using the technical content disclosed above, are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and variations made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
