[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] This utility model provides a fixing structure for welding production of road height restriction frames. This fixing structure can fix the metal rods after they are aligned by fixing components, so as to avoid the displacement of the workpiece during welding and thus prevent welding deviation. It can meet the needs of fixing metal rods of different specifications.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example

[0026] like Figures 1-5 As shown, a fixing structure for welding production of road height restriction frames includes: a pipe clamp a1, a pipe clamp b11 on the top of the pipe clamp a1, connecting plates 12 fixedly connected to the top two ends of the pipe clamp a1 and the bottom two ends of the pipe clamp b11 respectively, a fixing component, the fixing component is located on the top of the pipe clamp b11 and is used to support the metal rods of the height restriction frame, and an adjustment component is provided on the base 2.

[0027] Each of the connecting plates 12 has two mounting holes 5, and the two mounting holes 5 on the two opposite connecting plates 12 correspond to each other. A fixing bolt 51 is provided between the two opposite mounting holes 5.

[0028] In use, pipe clamps a1 and b11 are symmetrically clamped at the connection between the metal rods, and their positions are adjusted according to the actual situation. Then, fixing bolts 51 are passed through the two opposite mounting holes 5 respectively, and the two opposite connecting plates 12 are connected by fixing bolts 51. The tightness of fixing bolts 51 is adjusted according to the diameter of the metal rod, so that pipe clamps a1 and b11 clamp the metal rod. The fixing assembly is used to fix the metal rods that need to be welded together, so as to facilitate welding at the connection. Secondly, the support angle can be adjusted by adjusting the assembly, which can fix metal rods with different tilt angles, improving practicality. Example

[0029] Based on Embodiment 1, the fixing assembly includes: a base 2, a rotating plate 21, a support plate 22, and a magnet 23. The base 2 is fixedly connected to the top of the pipe clamp b11. The rotating plate 21 is provided on the top of the base 2. The support plate 22 is provided on the rotating plate 21. The magnet 23 is provided on the upper surface of the support plate 22. The pipe clamps a1, b11, and the inner wall of the support plate 22 are all arranged in a trapezoidal structure, and the pipe clamps a1, b11, and the inner wall of the support plate 22 are all provided with anti-slip textures 24.

[0030] In use, pipe clamps a1 and b11 are installed at the connection between the metal rods. The base 2 serves as a load-bearing element. The rotating plate 21, together with the support plate 22, supports the metal rods. The metal rods to be welded are placed on the support plate 22 and fixed by the magnet 23. The trapezoidal inner wall of the pipe clamps a1, b11, and support plate 22 can fix metal rods of different diameters. The magnet 23 is attached to the trapezoidal plane. The magnet 23 can be replaced. The appropriate thickness is rotated according to the diameter of the metal rod to be fixed, thereby attracting the metal rod and preventing it from moving. It is also easy to separate from the metal rod. Even when separated, the magnet 23 is attached to the surface of the metal rod, but since the surface of the metal rod is arc-shaped, it can be manually removed. This fixes the two metal rods connected at right angles without obstructing the welding line. Example

[0031] Based on Embodiment 1, the adjustment component includes: a connecting seat 3, a connecting block 31, a positioning hole 32, a threaded hole a33, and a through hole 34. One end of the rotating plate 21 is fixedly connected to the connecting seat 3, and the connecting block 31 is rotatably connected inside the connecting seat 3. The top end of the connecting block 31 is connected to the bottom of the support plate 22. The connecting seat 3 has several positioning holes 32. A threaded hole a33 is opened on one side of the inner wall of the connecting seat 3. A through hole 34 is opened on the other side of the connecting seat 3 at the position corresponding to the threaded hole a33. The several positioning holes 32 are arranged in a ring array. The threaded hole a33 and the through hole 34 are aligned with one of the positioning holes 32. A positioning screw 35 is provided inside the through hole 34. One end of the positioning screw 35 passes through one of the positioning holes 32 and extends into the threaded hole a33.

[0032] When it is necessary to fix the diagonal bracing metal rod, unscrew the positioning screw 35 from the threaded hole a33, then pull the positioning screw 35 out of the through hole 34 and the positioning hole 32, thereby releasing the fixation of the connecting block 31. Rotate the connecting block 31 to drive the support plate 22 to deflect and adjust the support angle. Fine-tune the connecting block 31 so that the through hole 34 is aligned with one of the positioning holes 32. At this time, the through hole 34, the positioning hole 32 and the threaded hole a33 are in a straight line. Then insert the positioning screw 35 into the positioning hole 32 and pass through the positioning hole 32. Then screw one end of the positioning screw 35 into the threaded hole a33 to fix the adjusted angle. Then place the metal rod diagonally on the support plate 22 for fixation and support.

[0033] The base 2 has a rotating cavity 4 at the top, and a rotating rod 41 is provided inside the rotating cavity 4. The bottom end of the rotating rod 41 is fixedly connected to a limit wheel 42, and the top end of the rotating rod 41 is connected to a rotating plate 21. A threaded hole b43 that communicates with the inside of the rotating cavity 4 is provided on one side of the base 2. A brake screw 44 is threadedly connected inside the threaded hole b43. One end of the brake screw 44 abuts against the limit wheel 42, and the other end of the brake screw 44 extends to the outside and is fixedly connected to a knob 45.

[0034] When the rotating plate 21 is reversed, screw the brake screw 44 out of the threaded hole b43 a certain distance, so that one end of the brake screw 44 is separated from the bearing of the limit wheel 42, thereby releasing the fixation of the limit wheel 42. Then rotate the rotating plate 21, which drives the rotating rod 41 and the limit wheel 42 to rotate inside the rotating cavity 4. The limit wheel 42 can also prevent the rotating plate 21 from falling off. After adjusting the orientation of the rotating plate 21, screw the brake screw 44 into the threaded hole b43, so that one end of the brake screw 44 abuts against the limit wheel 42, thereby fixing the limit wheel 42. This eliminates the need to remove the pipe clamps a1 and b11 to adjust the orientation.
