[0029] Please see Figures 1-5 A screen welding device includes a placement platform 1, a linkage component 2 on the placement platform 1, a connecting frame 3 on the linkage component 2, and an adjustment mechanism on the connecting frame 3. The adjustment mechanism includes a rotating shaft 4, a mounting plate 5, a welding head 6, and a positioning mechanism. The rotating shaft 4 is rotatably mounted on the connecting frame 3, the mounting plate 5 is fixed to the outer wall of the rotating shaft 4, and the welding head 6 is connected to the mounting plate 5. The positioning mechanism includes a positioning disc 7, a rotating disc 8, a positioning hole 9, an insertion hole 10, an insertion rod 11, and a locking mechanism. The positioning disc 7 is fixed to the outside of the connecting frame 3, the rotating disc 8 is fixed to the outer wall of the rotating shaft 4, and the positioning hole 9 is provided with multiple components. The positioning sleeve 12 is located on the outer wall of the positioning plate 7. The insertion hole 10 is located on the turntable 8. The insertion hole 10 is inserted into the positioning hole 9 and the insertion hole 10. The locking mechanism includes a positioning sleeve 12, a rotating rod 13, a locking block 14, a locking groove 15, a push spring 16, and a fixing sleeve 17. The positioning sleeve 12 is located at the top of the insertion rod 11. The rotating rod 13 is provided with multiple sets of rotating rods 13 and is mounted on the outer wall of the positioning sleeve 12. The locking block 14 is located at the bottom of the multiple sets of rotating rods 13. The locking groove 15 is provided with multiple sets distributed on the outer wall of the insertion rod 11. The push spring 16 is mounted on the outside of the positioning sleeve 12. The fixing sleeve 17 slides on the outer wall of the positioning sleeve 12 and is connected to the push spring 16.

[0030] The top of the insertion rod 11 is designed to be arc-shaped. The arc-shaped design reduces the resistance when the insertion rod 11 contacts the positioning sleeve 12, making the insertion smoother.

[0031] The outer sides of the multiple positioning holes 9 and the insertion holes 10 are all rounded. The rounded corner design allows the insertion rod 11 to be inserted more smoothly when it enters the positioning holes 9 and the insertion holes 10.

[0032] The spacing between multiple sets of positioning holes 9 is set to be equal. The uniform spacing ensures the consistency of each angle adjustment and facilitates precise positioning.

[0033] A compression spring 18 is installed on the inner top surface of the positioning sleeve 12. The bottom end of the compression spring 18 abuts against the top end of the insertion rod 11. The compression spring 18 provides elastic force during disassembly, which automatically ejects the insertion rod 11 from the positioning sleeve 12.

[0034] The inner wall of the positioning sleeve 12 is provided with guide strips 19, and multiple sets of guide strips 19 are provided. The outer wall of the insertion rod 11 is provided with guide grooves 20, and multiple sets of guide grooves 20 are provided and are slidably connected to multiple sets of guide strips 19 respectively. The cooperation between the guide strips 19 and the guide grooves 20 provides a stable movement trajectory for the insertion rod 11.

[0035] Each of the multiple rotating rods 13 has an unlocking block 21 at its top. The outer top of the positioning sleeve 12 has an upper push spring 22, and the bottom of the upper push spring 22 is equipped with an unlocking sleeve 23. By pushing the unlocking sleeve 23 to compress the upper push spring 22, the unlocking block 21 is driven to trigger the rotating rod 13 to rotate, thereby achieving rapid unlocking.

[0036] The outer side of the positioning sleeve 12 is provided with a slide bar 24. Multiple slide bars 24 are provided and are slidably connected to the unlocking sleeve 23 and the fixing sleeve 17 respectively. The slide bar 24 provides guidance for the unlocking sleeve 23 and the fixing sleeve 17 to ensure that they slide along the predetermined track.

[0037] In this embodiment, when the angle of the welding head 6 needs to be adjusted, the rotating turntable 8 drives the rotating rod 13 to rotate, the rotating rod 13 drives the mounting plate 5 to rotate, and the mounting plate 5 drives the welding head 6 to adjust its angle. When the angle is adjusted to a suitable angle, the positioning hole 9 is aligned with the insertion hole 10, the fixed sleeve 17 is pushed to press the lower push spring 16, and the insertion rod 11 is inserted into the positioning hole 9 and the insertion hole 10. Then the positioning sleeve 12 is inserted into the insertion rod 11, and the multiple sets of guide strips 19 are positioned and inserted into the guide groove 20. The top of the insertion rod 11 presses the compression spring 18, and the outer wall of the insertion rod 11 pushes the multiple sets of unlocking blocks 21 to move outward, thereby pushing the multiple sets of rotating rods 13 to rotate and drive the locking block 14 to engage in the locking groove 15. The fixed sleeve 17 is released, and the lower push spring 16 pushes the fixed sleeve 17 to abut against the outside of the multiple sets of locking blocks 14 to lock the insertion rod 11.

[0038] More specifically, when disassembly is required, first push the fixing sleeve 17 to compress the lower push spring 16, then push the unlocking sleeve 23 to compress the upper push spring 22. The unlocking sleeve 23 pushes multiple unlocking blocks 21 to make them rotate the rotating rod 13. The rotation of the multiple rotating rods 13 causes the locking block 14 to disengage from the slot 15, releasing the clamping of the insertion rod 11. The compression spring 18 elastically resets and pushes the insertion rod 11 out of the positioning sleeve 12. Then the insertion rod 11 can be pulled out of the insertion hole 10 and the positioning hole 9.

[0039] In summary, during the use or operation of the overall equipment: when the angle of the welding head 6 needs to be adjusted, the rotating turntable 8 drives the rotating rod 13 to rotate, the rotating rod 13 drives the mounting plate 5 to rotate, and the mounting plate 5 drives the welding head 6 to adjust its angle. When the angle is adjusted to a suitable angle, the positioning hole 9 aligns with the insertion hole 10, and the fixed sleeve 17 is pushed to press the lower push spring 16, inserting the insertion rod 11 into the positioning hole 9 and the insertion hole 10. Then, the positioning sleeve 12 is inserted into the insertion rod 11, and the multiple sets of guide strips 19 are positioned and inserted into the guide groove 20. The top of the insertion rod 11 presses the compression spring 18, and the outer wall of the insertion rod 11 pushes the multiple sets of unlocking blocks 21 to move outward, thereby pushing the multiple sets of rotating rods 13 to rotate and drive the locking block 14 to engage in the slot 15. The fixed sleeve 17 is released, and the lower push spring 16 pushes the fixed sleeve 17 to abut against the outside of the multiple sets of locking blocks 14, locking the insertion rod 11.

[0040] When disassembly is required, first push the fixing sleeve 17 to compress the lower push spring 16, then push the unlocking sleeve 23 to compress the upper push spring 22. The unlocking sleeve 23 pushes multiple unlocking blocks 21 to make the rotating rod 13 rotate. The rotation of the multiple rotating rods 13 causes the locking block 14 to disengage from the slot 15, releasing the clamping of the insertion rod 11. The compression spring 18 elastically resets and pushes the insertion rod 11 out of the positioning sleeve 12. Then the insertion rod 11 can be pulled out of the insertion hole 10 and the positioning hole 9.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
