Self-tightening motor positioning structure

Abstract

This invention discloses a self-tightening motor positioning structure, comprising a main body, a motor unit, and a drive belt. The belt connects a drive pulley and a driven pulley to drive a fan unit. The motor unit is connected to a base plate and a limiting slider, and a guide structure with a groove and limiting lip in the support frame allows the motor to slide freely within the slider. Furthermore, the restoring force of the tension bolts and tension springs automatically compensates for the tension of the drive belt, and multiple locking fasteners at the positioning points enhance overall stability and durability. This structure offers several advantages, including automatic tension adjustment, stable positioning, simplified structure, and convenient assembly.

Claims

1. A self-tightening motor positioning structure, characterized in that it comprises: A main body includes a motor and a drive wheel, the drive wheel being connected to a driven wheel via a transmission belt, which in turn drives a drive shaft and a fan to rotate; a base plate located below the motor, the base plate having a front and rear through hole, a limiting slider, a front bolt groove, a rear bolt groove, and limiting guide grooves on both sides; a support frame having a platform and at least one lower left bracket, the lower left bracket having an upper sliding groove, a lower sliding groove, a limiting lip, and a through hole, wherein the limiting guide grooves on both sides of the limiting slider... The limiting lip of the lower left bracket allows the limiting slider to slide and be positioned thereon; a positioning bolt passes through the front bolt groove and the through hole in the bottom plate, and is locked in the upper sliding groove to fix the motor position; a tension bolt passes through the rear bolt groove and the through hole in the bottom plate, and a tension spring is fitted on it. One end of the spring is fitted on the tension bolt with a buckle, and the other end is fixed by a fixing bolt through the through hole in the lower left bracket. The tension spring generates tension so that the motor device can automatically adjust its position to maintain the tension of the drive belt.

2. The self-tightening motor positioning structure as described in claim 1, wherein: The head of the positioning bolt is rectangular, with an outer diameter larger than the front bolt groove, and fits snugly into the upper sliding groove.

3. The self-tightening motor positioning structure as described in claim 1, wherein: The support frame includes at least one upper left bracket, one upper right bracket, one lower right bracket, and the lower left bracket, and each bracket has a locking hole at its end to lock it onto the outer casing.

4. The self-tightening motor positioning structure as described in claim 1, wherein: The limiting slider can be optionally assembled onto other support frames to enable the motor device to be installed and configured on supports in different positions.

5. The self-tightening motor positioning structure as described in claim 1, wherein: The limiting slider and the slide groove of the support frame cooperate to form a linear sliding structure, which allows the motor device to slide and adjust in a specific direction without producing lateral sway.

6. The self-tightening motor positioning structure as described in claim 1, wherein: The support frame has locking holes at its ends and is secured inside the fan housing with fasteners to enhance overall stability.

7. The self-tightening motor positioning structure as described in claim 1, wherein: The drive belt can be a flat belt, a V-belt, or a synchronous belt, and different tension designs can be selected according to the application.

8. The self-tightening motor positioning structure as described in claim 1 is suitable for fan devices, blowers, exhaust fans or other belt-driven power output devices.
