[0003] During the production process of circuit boards, components on their surface need to be soldered. When soldering these components, the circuit board is prone to displacement due to worker touch, resulting in misalignment of the soldered components. This necessitates workers to re-solder the components that need to be soldered, thus requiring a significant amount of time for the workers to solder the components on the circuit board.

[0004] To address this issue, we provide an anti-detachment structure for circuit board soldering to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-detachment structure for circuit board soldering. By combining a fixing shell, circuit board body, support frame, through hole and limiting structure, it solves the problem that circuit boards in the prior art do not have an anti-detachment function during soldering.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an anti-detachment structure for circuit board soldering, comprising a fixing shell and a limiting structure.

The lever 505 is trapezoidal in shape and extends through the first sliding groove 502 to the outside of the limiting shell 501.

[0027] Specifically: The support frame 3 positions and supports the fixed shell 1. When the staff needs to solder the components on the circuit board body 2, they directly insert the circuit board body 2 into the inner cavity of the fixed shell 1. When the circuit board body 2 enters the inner cavity of the fixed shell 1, it will push the two locking blocks 503 to both sides. When the circuit board body 2 is fully inside the inner cavity of the fixed shell 1, the first spring 504 will push the locking blocks 503 to reset, so that the locking blocks 503 lock the circuit board body 2.

[0028] Example 2

[0029] Please see Figure 1-5Based on Embodiment 1, a positioning shell 506 is fixedly connected to the top of the limiting shell 501. A second sliding groove 507 is provided on the top of the positioning shell 506. A second spring 508 is fixedly connected to the rear side of the inner cavity of the second sliding groove 507. A positioning block 509 is fixedly connected to the front side of the second spring 508. The positioning block 509 is trapezoidal in shape. A push block 510 is fixedly connected to the top of the positioning block 509. The top of the push block 510 extends through the second sliding groove 507 to the outside of the positioning shell 506. When the operator needs to remove the circuit board body 2, the operator pulls the lever 505 to both sides. When the lever 505 and the positioning block 506 are in contact, the lever 506 is fixedly connected to the positioning shell 506. When contact is made at 09, positioning block 509 will be pushed backward. When the lever 505 moves to the other side of positioning block 509, the second spring 508 will push positioning block 509 to lock lever 505. Lever 505 drives locking block 503 to position. At this time, the operator can pull the circuit board body 2 forward to remove the circuit board body. Limiting blocks 511 are fixedly connected to both sides of positioning block 509. The inner cavity of limiting block 511 is slidably connected to first limiting rod 512. The front and rear sides of first limiting rod 512 are fixedly connected to the inner wall of positioning shell 506. By setting limiting blocks 511 and first limiting rods, The combined use of 512 serves to limit the positioning of 509.

By setting the first fixing block 513, the second fixing block 514, and the second limiting rod 512... When used in conjunction with 5, the locking block 503 is limited during movement, thus ensuring the stability of the locking block 503 during movement. The front and rear sides of the limiting shell 501 are fixedly connected with the first fixing strip 516. The side of the first fixing strip 516 closest to the fixing shell 1 is fixedly connected to the fixing shell 1. By setting the first fixing strip 516, the limiting shell 501 is fixedly fixed. The bottom of both sides of the positioning shell 506 is fixedly connected with the second fixing strip 517. The bottom of the second fixing strip 517 is fixedly connected to the limiting shell 501. By setting the second fixing strip 517, the positioning shell 506 is fixedly fixed.

[0030] The working principle of this utility model is as follows: the support frame 3 positions and supports the fixed shell 1. When the operator needs to weld the components on the circuit board body 2, the circuit board body 2 is directly inserted into the inner cavity of the fixed shell 1. When the circuit board body 2 enters the inner cavity of the fixed shell 1, the circuit board body 2 will push the two locking blocks 503 to both sides. When the circuit board body 2 is completely inside the inner cavity of the fixed shell 1, the first spring 504 will push the locking blocks 503 to reset, so that the locking blocks 503 lock the circuit board body 2.
