Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board processing and production technology, specifically to a circuit board processing bracket. Background Technology
[0002] A circuit board, also known as a printed circuit board or PCB, is a core component in electronic equipment used to support and connect various electronic components. Its core function is to provide physical support for electronic components and realize electrical interconnection, while also undertaking the tasks of signal transmission and power distribution. In the daily processing and production of circuit boards, circuit board processing brackets are often used for clamping and fixing.
[0003] The prior art patent document CN221688923U provides a circuit board processing bracket, including a base plate. Support shafts are symmetrically arranged on both sides of the upper end of the base plate. Each support shaft has a support rod rotatably connected to it, and a positioning shaft is fixed to each support rod. Slide rods are also symmetrically arranged on both sides of the base plate, and sliders are slidably connected to them. Each slider is connected to a corresponding positioning shaft via a corresponding positioning rod. Each slider has a bolt threadedly connected to it. A limit shaft is also provided above the base plate, passing through two support rods. Nuts threadedly connected to the limit shaft are provided at both ends of the limit shaft. This device allows for adjustment of the circuit board's fixing height and tilt angle when fixing the circuit board, meeting user needs and facilitating circuit board processing.
[0004] Although existing circuit board processing brackets offer many advantages, they still suffer from the following problems: hinge connections and sliding components are prone to wobbling under stress, affecting processing accuracy and having low adjustment precision; secondly, traditional L-shaped fixed clamping plates are prone to stress concentration and can only clamp a single circuit board. Utility Model Content
[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.
[0006] 1. Technical problems to be solved:
[0007] To address the issues of insufficient adjustment accuracy and stress concentration in the clamping and fixing plate mentioned above, this utility model is proposed.
[0008] Therefore, the purpose of this utility model is to provide a circuit board processing bracket, which integrates a rack and pinion adjustment mechanism on the top of the slider. The pinion is rotated by rotating the knob, and the rack and pinion are used for lifting and lowering adjustment, resulting in higher adjustment accuracy. A ratchet spring pawl locking mechanism is designed at the bracket on the side wall of the rotating shaft to provide dynamic locking force. The response time is lower than that of the original nut locking structure. At the same time, the upper and lower fixing plates of the fixing component are designed as T-shaped fixing plate structures. The two T-shaped upper and lower fixing plates support bidirectional clamping, effectively increasing the contact area and avoiding the problem of stress concentration on one side of the traditional L-shaped plate.

[0037] Next, in order to lock the rotating shaft 310, specifically, the locking assembly 200 includes a connecting plate 250, a bracket 210 welded to the side of the connecting plate 250, a spring 240 welded to the side wall of the connecting plate 250 for resetting the pawl 230, a pawl 230 welded to the side wall of the spring 240, a hinged connection bracket 210 to the side wall of the pawl 230, the side wall of the pawl 230 closely abutting the ratchet 220, and the side wall of the ratchet 220 rotatingly connecting to the bracket 210.
[0038] Meanwhile, in order to clamp and fix the circuit board, specifically, the fixing component 300 includes a rotating shaft 310, a lower fixing plate 320 welded to the outer circumference of the rotating shaft 310, a telescopic rod 330 inserted into the top of the lower fixing plate 320, and a spring 340 sleeved on the outer circumference of the telescopic rod 330 for elastic pressing and clamping by the upper fixing plate 350.

[0043] Combination Figures 1-5 The specific usage process of the circuit board processing bracket of this embodiment is as follows:
[0044] 1: Simultaneously push the two limit brackets 121 to drive the two sliders 120 to slide inside the slide groove, thereby adjusting the position of the fixing component 300 laterally. By rotating the knob 141, the gear shaft 140 is rotated, and the gear shaft 140 drives the meshing rack 130 to rise and fall, thereby adjusting the height position of the fixing component 300.
[0045] 2: When it is necessary to rotate the fixed component 300, the toggle block 231 is moved to drive the pawl 230 to release the lock on the ratchet 220. Then the rotating shaft 310 can be rotated to adjust the angle position. When no adjustment is needed, the toggle block 231 is released, and the pawl 230 is reset by the elastic force of the spring 240 to lock the ratchet 220.
[0046] 3: Lift the upper fixing plate 350 upwards, and then place the circuit board to be processed on top of the lower fixing plate 320. The upper fixing plate 350 continues to descend due to the elastic deformation of the second spring 340. At this time, slowly lower the upper fixing plate 350, and the circuit board to be processed can be clamped and fixed in conjunction with the lower fixing plate 320. At the same time, due to the T-shaped structure of the upper fixing plate 350 and the lower fixing plate 320, two circuit boards to be processed can be clamped and fixed at the same time.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
