Detailed Description
Referring to the drawings, the synchronous belt tensioning and loosening structure comprises a synchronous belt tensioning seat 1, wherein a U-shaped groove body 14 is formed in the synchronous belt tensioning seat 1, tensioning seat cover plates 2 are fixedly connected to two sides of the synchronous belt tensioning seat 1 respectively, a steel sleeve shaft 9 is fixedly arranged between the upper edge of the U-shaped groove body 14 and the two tensioning seat cover plates 2, a steel sleeve 10 is sleeved on the steel sleeve shaft 9, and the steel sleeve is installed on the steel sleeve shaft to play a guiding role. A shaft 8 is pivoted on one tensioning seat cover plate 2, a synchronous belt tensioning wheel 3 is fixedly arranged on the shaft 8 on the inner side of the tensioning seat cover plate 2, and the synchronous belt tensioning wheel 3 is positioned in the U-shaped groove body 14; a ratchet wheel 4 is fixedly arranged on a shaft 8 at the outer side of the tensioning seat cover plate 2; a sliding groove 15 with an opening at the lower end is arranged on the tensioning seat cover plate 2, a sliding block 11 matched with the sliding groove can move up and down, a fixed plate 12 for sealing the sliding groove 15 is fixedly arranged at the lower end of the tensioning seat cover plate 2, a threaded hole is formed in the fixed plate 12, and an adjusting screw pivoted with the sliding block 11 is in threaded connection with the threaded hole; the sliding block 11 is also pivoted with a pawl 5, the tensioning seat cover plate 2 is also fixedly provided with a spring plate fixing plate 7, one end of a pawl spring plate 6 is fixedly arranged on the spring plate fixing plate 7, the other end of the pawl spring plate 6 is propped against the pawl 5, and the claw tip of the pawl 5 is propped against the ratchet wheel 4. The right end of the shaft 8 exceeds the ratchet wheel 4, the cross section is square, a through hole can be formed in the end of the shaft, and the shaft 8 can be rotated by a spanner or a screwdriver inserted into the through hole. The timing belt 100 bypasses the steel bushing, is wound on the inner side of the timing belt tensioning wheel, and a plurality of belt teeth of the timing belt are meshed with the gear teeth of the timing belt tensioning wheel.
When the synchronous belt is required to be tensioned, the anticlockwise rotating shaft 8 and the synchronous belt pulley rotate to drive the synchronous belt to be tensioned, and the pawl is matched with the ratchet wheel to lock.
When the synchronous belt is required to be loosened, the adjusting screw is matched with the sliding block to drive the pawl to move downwards, and when the pawl leaves the ratchet wheel, the shaft and the tension pulley of the synchronous belt can rotate clockwise to enable the synchronous belt to be loosened. Because the synchronous belt tensioning wheel is fixed in the relatively closed U-shaped groove body 14, the synchronous belt can only drive the synchronous belt tensioning wheel to rotate when the synchronous belt is loosened and can not be separated, and therefore danger can not occur.
