[0026] This specific embodiment is a spliced precision sheet metal part, the structural diagram of which is shown below. Figure 1-6 As shown, the assembly includes a first sheet metal part 1 and a second sheet metal part 2. Mounting plates 3 are symmetrically fixedly connected to the bottom ends of both the first sheet metal part 1 and the second sheet metal part 2. A mounting rod 4 with an L-shaped structure is fixedly connected to the top of the first sheet metal part 1. A fixing box 5 is fixedly connected to the top of the second sheet metal part 2. A through groove is provided on the outer side of the fixing box 5, through which the mounting rod 4 extends into the interior of the fixing box 5. A pressing block 6 is slidably connected to the inner side of the fixing box 5. A spring 7 is fixedly connected inside the pressing block 6. Symmetrically fixed to the bottom ends of the outer sides of the pressing block 6 are... There is an extension edge 8, and the extension edge 8 is slidably connected to a limiting block 9. By aligning the first sheet metal part 1 and the second sheet metal part 2 with each other, the mounting rod 4 and the fixing box 5 are respectively perpendicular to the top of the first sheet metal part 1 and the second sheet metal part 2. By sliding the extrusion block 6 towards the through groove, the spring 7 is extruded. Then the extension edge 8 moves synchronously with the extrusion block 6 to push the limiting block 9, inserting the mounting rod 4 into the inside of the through groove, and finally extending into the inside of the fixing box 5. The limiting block 9 extrudes the mounting rod 4.
[0027] In this embodiment, the limiting block 9 has an inclined groove 10 inside, and the top of the extended side 8 is fixedly connected to a positioning post 11. The positioning post 11 extends to the outside of the inclined groove 10. As the extended side 8 slides with the pressing block 6, the positioning post 11 presses the inclined groove 10 and has an inclined design with the inclined groove 10, which drives the limiting block 9 to unfold.
[0028] Secondly, in this embodiment, a disc 12 is rotatably connected inside the fixed box 5 and on the back of the extrusion block 6. A fixed rod 13 is fixedly connected to the eccentric part of the disc 12. An auxiliary rod 14 is slidably connected inside the fixed rod 13. A handle 15 is fixedly connected to the top of the auxiliary rod 14. A placement groove is opened at the top of the fixed box 5 corresponding to the position of the handle 15. By pulling the auxiliary rod 14 out inside the fixed rod 13 and then grasping the handle 15 and turning it, the fixed rod 13 drives the disc 12 to rotate. Since the fixed rod 13 is installed at the eccentric part of the disc 12, the maximum contact surface of the disc 12 contacts the extrusion block 6, thereby extruding the extrusion block 6. Then, the auxiliary rod 14 is pressed down, so that the auxiliary rod 14 slides into the inside of the fixed rod 13, and the handle 15 is inserted into the placement groove at the top of the fixed box 5, fixing the rotation angle of the disc 12 and preventing it from shifting.
[0029] In addition, in this embodiment, there are two sets of limiting blocks 9. The two sets of limiting blocks 9 are fixedly connected to the side of the opposite side of the two sets of limiting blocks 9. The outer wall of the mounting rod 4 is provided with a slot at the position corresponding to the insertion rod 16. As the limiting blocks 9 slide to both sides and expand obliquely, the insertion rod 16 will move synchronously and finally be inserted into the inside of the slot, so that the limiting blocks 9 limit and fix the mounting rod 4, thereby completing the splicing between the first sheet metal part 1 and the second sheet metal part 2.
[0030] Furthermore, in this embodiment, a connecting post 17 is fixedly connected to one end of the second sheet metal part 2 near the first sheet metal part 1. A through hole is opened in the interior of the first sheet metal part 1 at the position corresponding to the connecting post 17. After the mounting rod 4 is inserted into the interior of the fixing box 5, the connecting post 17 will be directly inserted into the interior of the through hole, further improving the splicing between the first sheet metal part 1 and the second sheet metal part 2 and reducing the gap between them.
[0031] Furthermore, in this embodiment, an arc-shaped block 18 is fixedly connected to the top of the inner side of the first sheet metal part 1, and an arc-shaped plate 19 is fixedly connected to the outer side of the arc-shaped block 18. A fixing ring 20 is fixedly connected to the top of the inner side of the first sheet metal part 1, and a rotating ring 21 is rotatably connected to the outside of the fixing ring 20. An extension block 22 is fixedly connected to the outside of the rotating ring 21, and a retaining rail 23 is fixedly connected to the outer end of the rotating ring 21 that is away from the extension block 22. The retaining rail 23 is adapted to the arc-shaped plate 19. By installing the arc-shaped block 18 and the fixing ring 20 to the top of the first sheet metal part 1 and the second sheet metal part 2 respectively, and keeping the arc-shaped plate 19 facing the second sheet metal part 2, the extension block 22 is grasped and moved. Then the rotating ring 21 slides outside the fixing ring 20, and finally the retaining rail 23 directly fits against the arc-shaped plate 19, and the splicing is easily completed.
[0032] When using the device of this technical solution, the first sheet metal part 1 and the second sheet metal part 2 are aligned with each other, so that the mounting rod 4 and the fixing box 5 are perpendicular to the top of the first sheet metal part 1 and the second sheet metal part 2 respectively. The mounting rod 4 is inserted into the through groove and finally extends into the fixing box 5. By pulling out the auxiliary rod 14 inside the fixing rod 13, and then grasping the handle 15 to turn it, the fixing rod 13 drives the disc 12 to rotate. Since the fixing rod 13 is installed at the eccentric position of the disc 12, the maximum contact surface of the disc 12 contacts the extrusion block 6, thereby extruding the extrusion block 6 and extruding the spring 7. Then the extension edge 8 moves synchronously with the extrusion block 6. Subsequently, the positioning post 11 extrudes the inclined groove 10 and has an inclined design with the inclined groove 10, which drives the limiting block 9 to unfold. The insertion rod 16 will move synchronously and finally be inserted into the slot, so that the limiting block 9 limits and fixes the mounting rod 4, thus completing the process. The first sheet metal part 1 and the second sheet metal part 2 are spliced together. Then, the auxiliary rod 14 is pressed down so that it slides into the interior of the fixing rod 13, and the handle 15 is inserted into the placement groove at the top of the fixing box 5. The rotation angle of the disc 12 is fixed to prevent it from shifting. After the mounting rod 4 is inserted into the interior of the fixing box 5, the connecting post 17 is directly inserted into the interior of the through hole, further improving the splicing between the first sheet metal part 1 and the second sheet metal part 2 and reducing the gap between them. By installing the arc block 18 and the fixing ring 20 to the top of the first sheet metal part 1 and the second sheet metal part 2 respectively, and keeping the arc plate 19 facing the second sheet metal part 2, the extension block 22 is grasped and turned. Then, the rotating ring 21 slides outside the fixing ring 20. Finally, the locking rail 23 directly fits into the arc plate 19, and the splicing is easily completed. Compared with the existing sheet metal parts, this utility model can improve the overall practicality of the sheet metal parts through design.
[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
