[0004] The aforementioned reference document utilizes an adjustment assembly and a positioning assembly to achieve processing of pipe bends at different angles. However, the reference document has the disadvantage that one side of the fastening frame of the adjustment assembly is designed at a right angle. When processing pipe bends at different angles, the right angle easily forms creases on the surface of the pipe, affecting the appearance and service life of the pipe. In addition, each time the position of the adjustment assembly and the positioning assembly is adjusted, the first and second positioning screws need to be manually loosened and tightened, which is a cumbersome and inconvenient operation.

[0005] In view of this, the utility model solves the above technical problems by proposing a fixing clamp for a pipe elbow. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1:

[0026] See also Figure 1-4As shown, a fixing fixture for a pipe elbow includes a frame 1, a plurality of sliding grooves 101 are provided on the top of the frame 1, and the inner cavities of the sliding grooves 101 are slidably connected with a positioning assembly 102 and an adjusting assembly 103, and a plurality of positioning holes 2 are provided on the top of the frame 1 outside the sliding grooves 101. The inner cavities of the positioning assembly 102 and the adjusting assembly 103 are both equipped with a locking assembly, and the locking assembly includes a positioning block 3, which is slidably connected to the inner cavities of the positioning assembly 102 and the adjusting assembly 103. The tops of the positioning assembly 102 and the adjusting assembly 103 are both fixed with a connecting block 301, and the inner cavity of the connecting block 301 is rotatably connected with a rotating shaft 302. A top block 303 is fixed to the surface of the rotating shaft 302, and a knob 304 is fixed to one end of the rotating shaft 302. A plurality of springs 305 are fixed to the opposite surfaces of the positioning block 3 and the positioning assembly 102 and the adjusting assembly 103. The surface of the positioning block 3 extends to the inner cavity of the positioning hole 2. The positioning assembly Circular plates 4 are fixed on both sides of 102 and the adjustment component 103. A plurality of threaded holes 5 are provided on the top of the frame 1 outside the positioning hole 2. By setting the threaded holes 5, the threaded holes 5 are mainly used to connect the support columns 501. The inner cavity of the threaded hole 5 is threadedly connected to the support column 501. By setting the support column 501, the support column 501 is used to support and stabilize the bent pipe. At the same time, the support column 501 is detachable and can adjust the position to meet the processing requirements of different angles. One end of the spring 305 is connected to the bottom end of the positioning block 3, and the other end of the spring 305 is fixedly connected to the top of the positioning component 102 and the adjustment component 103. The surface of the knob 304 is provided with anti-slip grooves. By providing anti-slip grooves on the surface of the knob 304, an anti-slip effect can be achieved when rotating the knob 304. The curvature of the arc plate 4 is adapted to the outer surface of the bent pipe, and the curvature of the arc plate 4 is adapted to the outer surface of the bent pipe to reduce contact pressure and avoid surface damage.

[0027] During processing, when it is necessary to adjust the position of the positioning component 102 and the adjusting component 103, first rotate the knob 304. The rotation of the knob 304 drives the rotating shaft 302 to rotate. The rotation of the rotating shaft 302 drives the top block 303 to rotate ninety degrees, so that the top block 303 is vertical and lifts the positioning block 3. When the positioning block 3 moves upward, the spring 305 extends, so that the surface of the positioning block 3 is separated from the inner cavity of the positioning hole 2. At this time, the position of the positioning component 102 and the adjusting component 103 can be adjusted. When the adjustment is completed, rotate the knob 304 again to make the rotating shaft 302 drive the top block 303 to rotate ninety degrees and make the top block 303 parallel. When the top block 303 is in a parallel state, the positioning block 3 is under the action of the contraction force of the spring 305. , automatically descends and snaps into the inner cavity of the positioning hole 2, thereby locking the positioning component 102 and the adjusting component 103. After locking is completed, one end of the elbow is placed into the inner cavity of the positioning component 102, and the positioning component 102 is used to fix one end of the elbow. Secondly, the other end of the elbow is placed into the inner cavity of the adjusting component 103, and the adjusting component 103 is used to fix the other end of the elbow. After the fixation is completed, the support column 501 is unscrewed, the position of the support column 501 is adjusted, and the support column 501 is used to support and stabilize the elbow. Secondly, the adjusting component 103 is rotated to process the elbow. During the processing, the surface of the elbow will contact the surface of the arc plate 4, avoiding the problem of the right-angle fastening frame causing creases on the surface of the elbow.
