[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 , an adjustable low-power PCB integrated circuit board, comprising a circuit board body 1 and a plurality of mounting holes arranged on the back thereof, a support tube 3 in communication with the mounting holes is fixedly connected to the back of the circuit board body 1, and is used to cooperate with an adjusting tube 2 to support the circuit board body 1, and an adjusting tube 2 is sleeved on one end of the support tube 3 away from the circuit board body 1, and is used to adjust the gap size after the circuit board body 1 is installed, and the adjusting tube 2 and the support tube 3 are threadedly connected, and a rubber ring 6 is fixedly connected to one end of the adjusting tube 2 away from the circuit board body 1, and is used to reduce the wear of the adjusting tube 2 after installation, and a plurality of rubber strips 9 are fixedly connected to the outer wall of the adjusting tube 2, and are used to play an anti-slip role when the user rotates the adjusting tube 2;

[0023] In this embodiment, a movable ring 4 is slidably sleeved on one end of the support tube 3 close to the circuit board body 1, which is used to prevent the block 10 from loosening. A rubber pad 8 is fixedly connected to one side of the movable ring 4 close to the adjusting tube 2, which is used to prevent wear between the movable ring 4 and the adjusting tube 2. A plurality of springs 5 ​​are fixedly connected between the movable ring 4 and the circuit board body 1, which are used to elastically support the movable ring 4. A block 10 is fixedly connected to one end of the movable ring 4 close to the adjusting tube 3, which is used to cooperate with the card slot to prevent the adjusting tube 2 from loosening. A card slot corresponding to the card block 10 is provided on one end of the adjusting tube 3 close to the circuit board body 1, and a plurality of card slots are distributed in an annular shape, and one end of the card block 10 slides and extends into the card slot;

[0024] In this embodiment, a guide block 7 is fixedly connected to the inner side wall of the movable ring 4, which is used to cooperate with the guide groove to keep the movable ring 4 moving in a straight line and prevent it from tilting (the movable ring 4 will drive the guide block 7 to move when it moves). A guide groove corresponding to the guide block 7 is provided on the outer side wall of the support tube 3. The end of the guide block 7 away from the movable ring 4 slides and extends into the guide groove. The end of the guide block 7 away from the movable ring 4 is provided with an arc groove. A ball is rollingly connected to the inner side wall of the arc groove for reducing the resistance of the guide block 7 when it moves, and part of the ball passes through the arc groove.

[0025] In this embodiment, the circuit board body 1 is first placed at the location where it needs to be installed (the location to be installed), so that the back side of the circuit board body 1 (the side where the adjustment tube 2 is installed) faces the installation location. At this time, the adjustment tube 2 supports the circuit board body 1, so that a certain gap is left between the circuit board body 1 and the installation location to avoid friction between the circuit board body 1 and the installation location and damage. Then, screws and bolts are inserted into the installation holes and penetrate the support tube 3 and the adjustment tube 2. Finally, the bolts and screws are tightened with the installation location to complete the installation and fixation of the circuit board body 1. At the same time, the gap between the circuit board body 1 and the installation location can be adjusted according to actual needs. First, push the movable ring 4 moves in the direction close to the circuit board body 1, and the block 10 is driven to disengage from the card slot through the movable ring 4. At this time, the adjusting cylinder 2 is manually rotated, and the adjusting cylinder 2 moves on the supporting cylinder 3 through the action of the threaded engagement, so that the adjusting cylinder 2 is close to or away from the circuit board body 1 (determined by the forward and reverse rotation of the adjusting cylinder 2 by the user). When the adjusting cylinder 2 is close to the circuit board body 1, the gap can be narrowed, and when the adjusting cylinder 2 is away from the circuit board body 1, the gap can be widened. After the adjustment is completed, the movable ring 4 is released, and the elasticity of the spring 5 pushes the movable ring 4 to move and reset in the direction of the adjusting cylinder 2, and the block 10 is driven to be inserted into the card slot through the movable ring 4, so that the adjusting cylinder 2 can be prevented from loosening.
