DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a control mainboard magnetic bracket, including an L-shaped frame 1 and a limit plate 2. A connecting rectangular hole 5 is opened at one end of the L-shaped frame 1, a rectangular connecting rod 3 is fixedly installed on the limit plate 2, and the rectangular connecting rod 3 slides with the connecting rectangular hole 5. An observation groove is opened on one side of the L-shaped frame 1, and a transparent observation window 101 is fixedly installed in the observation groove. A limiting slide groove 6 is opened in the L-shaped frame 1, and a limiting slider 7 is slidably installed in the limiting slide groove 6. The limiting slider 7 and the other end of the limiting plate 2 are fixedly installed with a strong magnetic magnet 9.

[0022] In this embodiment, the L-shaped frame 1 and the limit plate 2 can be slidably connected together by slidingly cooperating with the rectangular connecting rod 3 and the connecting rectangular hole 5, so that the device is clamped at the front and rear ends of one side of the control main board. Moving the limit slider 7 can drive the strong magnetic magnet 9 to move, so that the strong magnetic magnet 9 on the limit slider 7 is close to the strong magnetic magnet 9 on the rectangular connecting rod 3. The internal situation of the connecting rectangular hole 5 can be directly observed through the transparent observation window 101, so as to facilitate the adjustment of the limit slider 7 to a suitable position. The two strong magnetic magnets 9 cooperate with each other to attract and pull the limit plate 2 toward the L-shaped frame 1, and clamp the control main board at the center position. The two devices cooperate with each other to clamp and fix the two sides of the main board respectively. Figure 4 As shown, control motherboards of any size can be clamped.

[0023] In order to limit the mainboard from sliding up and down, the device is implemented by the following technical solution: a groove 102 is provided on the inner wall of the L-shaped frame 1 , and fixing holes 4 are provided on the L-shaped frame 1 and the limiting plate 2 .

[0024] The groove 102 can be used to limit the mainboard from sliding up and down, and the fixing hole 4 is used to fix the device on the host housing.

[0025] Among them, in order to achieve the purpose of moving the limit slider 7, the present device is implemented by adopting the following technical scheme: a threaded adjustment shaft 8 is rotatably installed in the L-shaped frame 1, an inner angle groove 801 is opened at one end of the threaded adjustment shaft 8, a threaded through hole 701 is opened in the limit slider 7, the threaded through hole 701 is threadedly matched with the threaded adjustment shaft 8, and the observation groove is connected with the connecting rectangular hole 5.

[0026] The threaded adjustment shaft 8 can be rotated by an internal angle wrench through the internal angle groove 801, and the threaded adjustment shaft 8 is threadedly matched with the threaded through hole 701, so that the rotation of the threaded adjustment shaft 8 can drive the limit slider 7 to move, and the movement of the limit slider 7 can drive the strong magnetic magnet 9 to move.

[0027] The working principle and use process of the utility model are as follows: when using, the device needs to be placed in a suitable position, and one corner of the control mainboard needs to be inserted into the groove 102, and then the rectangular connecting rod 3 is inserted into the connecting rectangular hole 5, and the threaded adjustment shaft 8 is rotated using an internal angle wrench. The rotation of the threaded adjustment shaft 8 will drive the limit slider 7 to move, and the position of the strong magnetic magnet 9 on the limit slider 7 is observed through the transparent observation window 101. The mutual attraction of the two magnets on the rectangular connecting rod 3 and the limit slider 7 is used to generate a certain pulling force on the rectangular connecting rod 3, thereby pulling the limit plate 2 to squeeze and clamp the mainboard, and the same method is used on the other side, and then the devices on both sides of the control mainboard are fixed to the main housing using the limit plate 2.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
