[0021] The technical solutions of the embodiments of the present utility model will be explained and described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0022] The following specifically describes a wave soldering anti-floating high-load fixture for a circuit board according to an embodiment of the present utility model with reference to the accompanying drawings.

[0023] Embodiment 1

[0024] For ease of understanding, please refer to Figures 1 to 4 , an embodiment of a wave soldering anti-floating high-load fixture for a circuit board provided by the present utility model, including a fixed shell 1, and an adjustment component is provided on the inner wall of the fixed shell 1; the adjustment component includes a first lead screw 7, a limit rod 14, two connecting plates 4, a first baffle 3 and two second baffles 13. The first lead screw 7 is rotatably installed on one side of the inner wall of the fixed shell 1, the limit rod 14 is fixedly installed on the other side of the inner wall of the fixed shell 1, the two connecting plates 4 are threadedly connected to the outer wall of the first lead screw 7, the first baffle 3 is fixedly installed on one side of the connecting plate 4, and the two second baffles 13 are arranged at the bottom end of the fixed shell 1.

[0025] It should be noted that by setting the adjustment component and turning the knob 6, the connecting plate 4 and the fixing pad 5 can be driven to move synchronously towards the middle of the fixed shell 1, which is convenient for adjusting the installation space when installing the circuit board. Moreover, the edge of the circuit board can be blocked by the first baffle 3 and the second baffle 13 to reduce the entry of solder water into the fixture; by setting the first lead screw 7, the connecting plate 4 can be driven to move, by setting the connecting plate 4 and the fixing pad 5 to fix the circuit board, and by setting the limit rod 14 to limit the connecting plate 4 when the connecting plate 4 moves.

[0026] In some embodiments, as Figure 3 shown, the two ends of the first lead screw 7 have opposite threads with the middle as the boundary. The two connecting plates 4 are respectively arranged at both ends of the first lead screw 7. Threaded holes and moving holes are respectively opened at both ends of the connecting plate 4. The connecting plate 4 is threadedly connected to the outer wall of the first lead screw 7 through the threaded hole, and the connecting plate 4 is slidably installed on the outer wall of the limit rod 14 through the moving hole. A fixing pad 5 is fixedly installed on one side of the connecting plate 4.

[0027] It should be noted that when installing the circuit board, the staff holds the circuit board and moves it to the middle position inside the fixed shell 1, and turns the knob 6 with the other hand to make the first lead screw 7 rotate. The rotation of the first lead screw 7 drives the two connecting plates 4 at both ends to move synchronously and reversely towards the circuit board direction, clamp the circuit board, and press down the circuit board to complete the installation of the circuit board.

[0028] In some embodiments, as Figure 2As shown in the figure, a chute 12 is opened at the bottom end of the fixed housing 1, and two second baffles 13 are slidably installed on the inner wall of the chute 12.

[0029] It should be noted that a rubber pad can be provided on the inner wall of the chute 12. The rubber pad is located between the chute 12 and the second baffle 13, which can increase the resistance when the second baffle 13 slides.

[0030] Embodiment 2

[0031] In some embodiments, as Figure 4 shown in the figure, rotating members 8 are fixedly installed at both ends of the first lead screw 7. The first lead screw 7 is rotatably installed on the inner wall of the fixed housing 1 through the rotating members 8. The rotating members 8 extend to the outside of the fixed housing 1. One end of one of the rotating members 8 is fixedly installed with a knob 6, and one end of the other rotating member 8 is fixedly installed with a second lead screw 9. A fixed nut 10 is threadedly connected to the outer wall of the second lead screw 9. A notch 11 is opened at one end of the inner wall of the fixed housing 1, and an upper cover 2 is fixedly installed at the top end of the fixed housing 1 through screws.

[0032] It should be noted that by providing the fixed nut 10, when the connecting plate 4 clamps the circuit board, the fixed nut 10 is tightened, and the first lead screw 7 is fixed by pressing one end of the fixed nut 10 against the fixed housing 1, which is convenient for fixing the first lead screw 7.

[0033] Working principle: When installing the circuit board, the staff holds the circuit board by hand and moves it to the middle position inside the fixed housing 1, and turns the knob 6 with the other hand to make the first lead screw 7 rotate. The rotation of the first lead screw 7 drives the connecting plates 4 at both ends to move synchronously and reversely towards the circuit board to clamp the circuit board and press the circuit board down to complete the installation of the circuit board. Then, the second baffle 13 is moved to align on both sides of the circuit board to block both sides of the circuit board.

[0034] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
