Embodiment
With reference to figure 2, select gear-shifting flexible shaft clamping to overlap the first clamping cover that assembly adopts in the present embodiment 13 has the first through hole 131, is positioned at the first flange 132 that 13 ends are overlapped in the first clamping, the first card base 133 and the second card base 134 axially extended from the opposite side of the first flange 132.Distance D between first card base 133 and the second card base 134 is greater than the diameter d of the first through hole 131.First clamping cover 13 also has between the 3rd flange the 135, three flange 135 and the first card base 133, second card base 134 and has interval 136.
With reference to figure 3, the second clamping cover 14 selecting gear-shifting flexible shaft clamping to overlap assembly employing in the present embodiment has the second through hole 141, is positioned at the hole clipping 142 of the both sides of the second through hole 141.First card base 133 and the second card base 134 can insert a hole clipping 142 respectively and with its snap-fit engagement.
With reference to figure 4, the third through-hole 151 that select gear-shifting flexible shaft clamping the to overlap lining 15 that assembly adopts in the present embodiment has the second flange 152, is positioned at the first insertion part 153 of the second flange 152 both sides and the second insertion part 154, runs through the first insertion part 153 and the second insertion part 154 and the second flange 152.Second flange 152 has annular groove 155 in inside.
With reference to figure 5, during assembling, the first through hole 131 of the first clamping cover 13 is inserted in first insertion part 153 of lining 15, then guide pipe 19 is inserted in the third through-hole 151 of lining 15, again jacket joint 18 is inserted in third through-hole 151, then the second insertion part 154 of lining 15 is inserted the second through hole 141 of the second clamping cover 14, then the first card base 133 of the first clamping cover 13 and the second card base 134 and the second clamping are overlapped hole clipping 142 snap-fit engagement of 14, second flange 152 of lining 15 is limited to the first card base 133, second card base 134 and the second clamping are overlapped in 14 spaces formed.One end of dust-proof cover 16 has reducing 161, and reducing 161 and the first flange 132 are connected together, and axial limiting is carried out in the 3rd flange 135 pairs reducing 161.In fact, also can reducing 161 immediate roof be carried out spacing at the first card base 133 and the second card base 134 place, but the 3rd flange 135 and the interval 136 between the first card base 133 and the second card base 134 make the 3rd flange 135 can be pushed up by the reducing 161 of dirt-proof boot 16 and produce deformation to two card bases, thus the clamping of overlapping between 13 for dirt-proof boot 16 and the first clamping provides pretightening force, and dust-proof cover 16 is allowed to have certain adjustment amount in the axial direction.The outer pillar 17 of flexible axle inserts in jacket joint 18, for flexible axle provides protection.One end away from reducing 161 of dust-proof cover 16 is locked at and selects on the push rod 21 of gear-shifting flexible shaft by collar 20.
Comparison diagram 1 and Fig. 5 visible, limit the position of lining 15 with the clamping of the first cutting ferrule 13 and the second cutting ferrule 14 in the present embodiment, and dust-proof cover 16 and the first cutting ferrule 13 clamping, formed the sealing protection selecting gear-shifting flexible shaft, without the need to independent stuffing box gland 5, and only needing a collar 20, amount of parts is few compared with prior art, easy to assembly.
In installation and practical process, annular groove 156 due to the second flange 155 inside is conducive to the intensity of reduction by second flange 155, thus make lining 15 can be compressed between the first clamping cover 13 and the second clamping cover 14 line length adjust and provide the first clamping overlap 13 and second clamping overlap pretightening force between 14.
In order to improve corrosion resistance, preferably, the first clamping cover 13 second clamping cover 14 in the present embodiment is working of plastics.
Although the utility model is described in conjunction with above embodiment, but the utility model is not defined to above-described embodiment, and only by the restriction of claims, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present utility model and scope.
