Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation is given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 2 to 4, the present embodiment relates to a belt tension adjusting device, including motor 1, load 2 and base 3, motor 1 bottom is provided with installing support 4, the main shaft of motor 1 is connected through belt drive with load 2, base 3 includes roof 31, short side plates 32 that are located the roof both ends, and long side plates 33 of roof both sides, be equipped with bar guiding hole 311 in the middle of roof 31, be provided with mounting bolt 34 in the bar guiding hole 311, mounting bolt 34 is fixed through mounting nut 35 with installing support 4, the bolt head of mounting bolt 34 has chucking part 341, chucking part 341 is the notch cuttype, the upper end is gone into bar guiding hole 311, the lower extreme plays the effect of chucking bar guiding hole 311 lower limb when mounting bolt 34 connects motor 4. The middle part of the strip-shaped guide hole 311 is also provided with a disassembly hole 312, and the disassembly hole 312 is square; the short side plate 32 is provided with an adjusting bolt 36, the bolt tail of the adjusting bolt 36 is oppositely arranged, and the bolt tail end of the adjusting bolt 36 is abutted against two sides of the mounting bracket 4, so that the horizontal position movement of the motor 1 is limited. Two long side plates 33 are further mounted on two sides of the base 3, and three fixing seat lugs 331 are arranged at the lower end of each long side plate 33 and used for fixing the base 3.
