Description

Technical Field

[0002] A circuit board is a fundamental component of electronic devices, used to implement complex circuit layout design and electrical signal transmission within electrical and electronic equipment. A circuit board, also known as a printed circuit board (PCB), is a support that connects electronic components and circuits. It is typically made from fiberglass and processed through processes such as copper cladding, gold plating, and etching. During use, the circuit board is primarily supported and secured by a circuit board bracket.

[0003] After searching, patent application number N200820150839.3 discloses a circuit board bracket for supporting a circuit board with multiple supporting parts. The circuit board bracket is composed of two parallel longitudinal supporting members and two parallel transverse supporting members to form an adjustable load-bearing frame. The supporting parts of the circuit board are inserted into the first and second slots of the two longitudinal supporting members and the two transverse supporting members, which facilitates the inspection of the circuit board in an inverted state. This design solves the defects of the existing technology.

[0004] However, this patent still has some shortcomings. During actual use, this type of circuit board needs to first place two horizontal support members and a vertical support member on the bottom of the circuit board for assembly, and then use an external wrench to drive the nut to rotate so that the nut is threadedly connected to the locking member to fix the circuit board. During the disassembly and assembly process of the circuit board, the horizontal support members and the vertical support members need to be re-assembled, which is inconvenient to use. In addition, external tools need to be carried to tighten the nuts during installation. The operation steps are cumbersome and time-consuming, which makes the disassembly and assembly of the circuit board low in efficiency.

[0005] To this end, we propose a circuit board holder with a quick-release function. Utility Model Content

A limiting member 15 is provided on the top of the two first positioning rods 11 and the second positioning rod 14. A circuit board body 4 is provided on the top of the fixed beam 1 and the movable beam 2, and a mounting hole 18 is provided on the circuit board body 4.

[0023] The two first positioning rods 11 and the second positioning rod 14 are both provided with a rotation groove 16, and the multiple rotation grooves 16 are rotatably connected with a rotating member 17. The top ends of the multiple rotating members 17 are respectively fixedly mounted on the corresponding limit members 15, and the limit members 15 can be limited by the rotating members 17. The multiple rotating members 17 are all set as convex cylinders. This design is conducive to the use of this device. The bottom ends of the two second positioning rods 14 are both fixedly mounted with a slider 13. The fixed beam 1 and the movable beam 2 are both provided with a slide groove 12. The two sliders 13 are respectively slidably connected to the corresponding slide groove 1 2, the two second positioning rods 14 can be limited by the slider 13, and the two cross frames 3 are provided with limiting grooves 9. Two limiting blocks 10 are fixedly installed at the bottom end of the mobile beam 2. The two limiting blocks 10 are slidably connected in the limiting grooves 9.
