Description

Technical Field

[0001] This utility model relates to the field of metal elbow technology, specifically a type A 45° metal elbow. Background Technology

[0002] In piping systems, elbows are pipe fittings used to change the direction of pipelines. They are most commonly classified by angle: 45°, 90°, and 180°. Other non-standard angle elbows, such as 60°, are also available depending on project requirements. Elbows are made from materials including cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics. Type A elbows typically bend the pipe into a smooth arc with a smaller inner bending radius, while Type B elbows bend the pipe into a more right-angled shape with a relatively larger inner bending radius. This difference in shape makes Type A elbows visually more streamlined, while Type B elbows emphasize their right-angle characteristics.

[0003] Existing A-type metal elbows typically maintain only a single angle during use and cannot be adjusted according to actual usage conditions, greatly reducing the flexibility of metal elbow use and hindering its application. Therefore, those skilled in the art provide an A-type 45° metal elbow to solve the problems mentioned in the background art. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by setting an adjusting screw, the lifting block can be driven to move up and down. The lifting block drives the movable rod to move. The movable rod can drive the push rod and the rotating frame to rotate with the end of the round rod as support. The rotating frame can drive the second connecting flange to rotate with the center of the round rod as support point. Thus, the relative angle between the first connecting flange and the second connecting flange can be adjusted, which is beneficial to improving the flexibility of the metal elbow in actual use.

[0015] 2. In this utility model, by setting an auxiliary rod and providing an arc-shaped groove inside the rotating frame to accommodate the auxiliary rod, a stable auxiliary support can be provided for the rotating frame. By setting an indicator plate, scale lines and indicator arrows, the operator can easily observe the actual rotation angle of the rotating frame, thereby achieving precise adjustment of the metal elbow, which is beneficial to the practical application of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 In this embodiment of the utility model, an A-type 45° metal elbow includes an elbow body, which includes a metal pipe 1 and a bent pipe 2 that are fixedly connected. A first connecting flange 3 is welded to the bottom end of the metal pipe 1, and a second connecting flange 4 is fixedly installed at the top end of the bent pipe 2. A fixed bracket is welded to the outer ring of the first connecting flange 3 and rotatably connected to the top end of the second connecting flange 4. Adjusting brackets that rotate around the top end of the fixed bracket together with the second connecting flange 4 are connected to both sides of the second connecting flange 4. An adjusting component for controlling the support angle of the adjusting bracket is installed on the fixed bracket.

[0022] In use, the first connecting flange 3 is used to assemble the metal pipe 1 and its connecting pipe. The second connecting flange 4 connected to the top of the bent pipe 2 can be adjusted in angle according to the actual connecting pipe. The operator rotates the adjustment component, which drives the adjustment bracket to rotate, so as to easily adjust the rotation angle of the bent pipe 2 relative to the axis of the metal pipe 1, such as 45° or 60° commonly used for metal elbows. Then, the second connecting flange 4 is used to install another set of connecting pipes.

[0023] In one embodiment, the fixed bracket includes a fixed plate 5 welded to the outer ring of the first connecting flange 3, a vertical plate 6 welded to the top of the fixed plate 5, a round rod 7 rotatably connected to the second connecting flange 4 fixedly installed at the top of the vertical plate 6, the two ends of the round rod 7 being connected to the adjusting bracket, and the top of the vertical plate 6 providing a rotation support point for the second connecting flange 4.

[0024] The adjusting bracket includes a semi-circular rotating frame 8 rotatably connected to the end of the round rod 7. One end of each of the two sets of semi-circular rotating frames 8 is fixedly connected to the outer ring of the second connecting flange 4 via a connecting rod 9. A push rod 10 is fixedly installed between the other ends of the two sets of semi-circular rotating frames 8. The push rod 10 is connected to the adjusting component. The adjusting component can drive the push rod 10 and the rotating frame 8 to rotate with the end of the round rod 7 as support. The rotating frame 8 can drive the second connecting flange 4 to rotate with the center of the round rod 7 as support point, thereby adjusting the relative angle between the first connecting flange 3 and the second connecting flange 4.

[0025] Furthermore, an auxiliary rod 11 is fixedly installed on the side of the upright plate 6, penetrating the rotating frame 8. The interior of the rotating frame 8 has an arc-shaped groove 12 that provides space for the auxiliary rod 11, providing stable auxiliary support for the rotating frame 8. An indicator plate 13 is fixedly installed inside the rotating frame 8, with a scale line 14 on the indicator plate 13 to display the rotation angle of the rotating frame 8. An indicator arrow 15 pointing to the scale line 14 is fixedly installed at the end of the auxiliary rod 11 away from the upright plate 6, which allows the operator to easily observe the actual rotation angle of the rotating frame 8, thereby achieving precise adjustment of the metal elbow.

[0026] Based on the above embodiments, specifically, the adjustment component includes an adjustment screw 16 rotatably connected to the fixed plate 5, a lifting block 17 threadedly connected to the adjustment screw 16, a vertical rod 18 slidably passing through the lifting block 17 welded to the fixed plate 5, and movable rods 19 rotatably connected to the top of the lifting block 17 on both sides.

[0027] The operator rotates the adjusting screw 16, which causes the lifting block 17 to slide up and down on the surface of the upright 18. The lifting block 17 drives the movable rod 19 to move, and the movable rod 19 drives the push rod 10 connected to its top to move. Furthermore, a positioning block 20 is welded to the side of the upright plate 6. The positioning block 20 is rotatably connected to the top of the adjusting screw 16 and welded to the top of the upright 18, which can improve the overall stability of the adjusting assembly. A knob 21 is fixedly installed at the bottom of the adjusting screw 16, which allows the operator to rotate the adjusting screw 16 using the knob 21.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
