[0022] The invention is further described in detail below with reference to the accompanying drawings.

[0023] The same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top", "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] As shown in the figure, a structurally stable PCB mainboard mounting device includes a housing bottom plate 1, a mounting plate 2 is arranged on the surface of the housing bottom plate 1, a PCB mainboard 3 is arranged on the surface of the mounting plate 2, a first end positioning rod 4 is arranged on one end of the surface of the mounting plate 2, a second end positioning rod 5 parallel to the first end positioning rod 4 is arranged on the surface of the mounting plate 2 at the other end of the first end positioning rod 4, the PCB mainboard 3 is located between the first end positioning rod 4 and the second end positioning rod 5, and also includes a first driving member 6 for driving the second end positioning rod 5 to move toward the first end positioning rod 4 and clamp and position the PCB mainboard 3. Positioning grooves 7 for inserting the PCB mainboard 3 are provided at the bottom of the side walls opposite to the first end positioning rod 4 and the second end positioning rod 5.

[0025] When installing the PCB main board 3, the mounting plate 2 is fixedly mounted on the surface of the casing bottom plate 1, and the first end positioning rod 4 is used to position one end of the PCB main board 3. The second end positioning rod 5 is driven by the first driving member 6 to move toward the PCB main board 3 to position the other end thereof. The two ends of the PCB main board 3 are inserted into the two positioning grooves 7, and under the clamping action of the first end positioning rod 4 and the second end positioning rod 5, the stability of the PCB main board 3 after installation is ensured, and the installation efficiency can be effectively improved.

[0026] T-shaped blocks 8 are provided at the bottom of both ends of the second end positioning rod 5, and T-shaped slots 9 for sliding connection of the T-shaped blocks 8 are provided on the surface of the housing bottom plate 1 on both sides of the mounting plate 2, and the first driving member 6 includes tension springs provided at both ends of the second end positioning rod 5, and hooks 10 for hanging the tension springs are provided on the surface of the mounting plate 2 on both sides of the mounting plate 2. Pulling the tension spring causes the second end positioning rod 5 to move toward the PCB main board 3, and one end of the tension spring is hung on the hook 10, and under the tension of the tension spring, the second end positioning rod 5 and the first end positioning rod 4 tighten the PCB main board 3 to ensure the stability of the PCB main board 3.

[0027] A groove 11 for placing the mounting plate 2 is provided on the surface of the casing bottom plate 1, and the depth of the groove 11 is equal to the thickness of the mounting plate 2. The lower surface of the second end positioning rod is in contact with the surface of the casing bottom plate 1 and the mounting plate 2, and the mounting plate 2 is embedded in the groove 11. When the second end positioning rod 5 abuts against the PCB mainboard 3, it is located above the groove 11 and placed on the surface of the mounting plate 2 to limit the mounting plate 2.

[0028] The two side walls of the mounting plate 2 are provided with limiting grooves 12 along the length direction thereof, and the bottoms of the two ends of the first end positioning rod are provided with connecting blocks 13 that are in contact with the two side walls of the mounting plate 2, and the inner wall of the mounting groove is provided with a sliding groove 14 for the connecting block 13 to slide, and the inner surface of the connecting block 13 is provided with a limiting block 15 slidably connected to the limiting groove 12, and the side of the limiting block 15 facing away from the second end positioning rod is provided with an insertion rod 16, a side wall at one end of the mounting plate 2 is provided with a through hole for the insertion rod 16 to pass through, and the inner wall at one end of the groove 11 is provided with a slot 17 for the insertion of the insertion rod 16, and a spring (not shown in the figure) is provided in the slot 17.

[0029] When the tension spring is pulled to drive the second end positioning rod 5 to move toward the PCB main board 3, the PCB main board 3 and the first end positioning rod 4 are also driven to move toward one end of the slot, so that the insertion rod 16 is inserted into the slot to limit the other end of the mounting plate 2. At the same time, the end of the insertion rod 16 abuts against the spring, and the spring is compressed. When the tension spring is released, the elastic force of the spring pushes the insertion rod 16 out of the slot, so that the first end positioning rod 4 is reset, which is convenient for its later disassembly.

[0030] The surface of the mounting plate 2 is provided with side positioning rods 18 on both sides of the PCB main board 3, and the surface of the mounting plate 2 is provided with a sliding groove 19 parallel to the first end positioning rod 4 between the first end positioning rod 4 and the second end positioning rod 5. The bottom of the side positioning rod 18 is provided with a sliding block 20 slidably connected to the sliding groove 19, and also includes a second driving member 21 for driving the two side positioning rods 18 to move relative to or away from each other. The second driving member 21 includes a connecting rod hinged to the top of the side positioning rod 18, and the other ends of the two connecting rods are hinged to the middle of the surface of the first end positioning rod 4.

[0031] When the tension spring is pulled and drives the second end positioning plate to move toward the first end positioning plate, when the second end positioning plate abuts against the PCB main board 3, it continues to drive it to move, so that the first end positioning rod 4 also moves accordingly. Under the action of the connecting rod, the two side positioning rods 18 are driven to move relative to each other to clamp the two sides of the PCB main board 3. At the same time, the tension spring is hung on the hook 10 to further improve the stability of the PCB main board 3 after installation.

After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the invention, they are protected by the patent law.
