12nd, long and narrow through hole 13, bolt 14.
Embodiment：As depicted in figs. 1 and 2, the toothed belt tension device in the present embodiment mainly includes, base 1, tooth form block
2 and toothed belt compact heap, wherein tooth form block 2 and toothed belt compact heap is separately mounted to inside the semi-enclosed cavity of base 1, and tooth
Shape is located at the top of tooth form block 2 with compact heap.
As in Figure 2-4, the section of base 1 is trapezoidal, and the both ends open of its internal semi-enclosed cavity is ramp-like in dipping down.
Respectively place one piece of tooth form block 2, the cavity side that 2 edge of tooth form block is surrounded with base 1 in the semi-enclosed cavity left and right ends that base 1 surrounds
Edge is concordant, and 2 surface of tooth form block is provided with the double wedge to match with the tooth form in toothed belt 3.Long and narrow through hole is offered on base 1
13, bolt 14 is provided with long and narrow through hole 13, and tooth form block 2 is fixed on by bolt 14 in the semi-enclosed cavity that base 1 surrounds, narrow
Long through-hole 13 is used to decompose the power that tooth form block 2 is applied, and extends the service life of bolt 14, avoids stuck.
As shown in figure 3, toothed belt compact heap is divided into respectively constitutes corresponding two parts with two tooth form blocks 2, a part
For handle compact heap 4, another part is tension compact heap 6.As shown in figure 4, handle compact heap 4 is Z-type compressing structure 9 and handle
5 combination, is fixedly connected to form one between the two, and wherein Z-type compressing structure 9 is used to compress toothed belt.Tensing compact heap 6 is
The combination of Z-type compressing structure 9 and tightening structure 7, tightening structure 7 are fixedly connected on one end of Z-type compressing structure 9.Tightening structure 7
Perpendicular to 9 upper surface of Z-type compressing structure, gap is left between the handle 5 on tightening structure 7 and handle compact heap 4.Tightening structure
Offered on 7 and tense hole, turnbuckle 8 is equipped with the hole, turnbuckle 8 is used to connect tightening structure 7 and handle 5.Z-type compresses
Hold-down bolt 10 is further respectively had in structure 9,10 direction of hold-down bolt is located at tooth form block 2 perpendicular to 1 base of base for compressing
The toothed belt 3 on surface.By adjusting the elastic adjustable tension compact heap 6 of turnbuckle 8 and hold-down bolt 10 to toothed belt 3
Compression degree is tensed, the service life for not only improving toothed belt also improves the adjusting efficiency that toothed belt compresses work.
Z-type compressing structure 9 on toothed belt compact heap is located at the waist of trapezoidal base 1（That is the two of semi-enclosed cavity
