Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
- 4 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of chemical pump Fluorine-lined axis and compared with large-diameter hold tightly
Ring locks new design structure, passes through hexagonal including lower locating ring 1, upper locating ring 2 and intermediate holding circle 3, the lower locating ring 1
Screw 5 is fixedly connected with locating ring 2, and intermediate holding circle 3, the centre are connected with inside the lower locating ring 1 and upper locating ring 2
It is connected with axle sleeve 4 inside holding circle 3, lower 1 both ends of locating ring symmetrically open up that there are two lower positioning screw hole 7, the lower positioning
It is fixedly connected with lower oblique angle 9 inside ring 1, upper 2 both ends of locating ring symmetrically open up that there are two upper positioning screw holes 8, described fixed
Top rade 10 is fixedly connected with inside the ring 2 of position, and intermediate 3 both ends of holding circle are symmetrically fixedly connected with the lower oblique angle 9 of cooperation and upper
The middle oblique angle 11 at oblique angle 10 offers the open slot 6 of cooperation axle sleeve 4 inside the intermediate holding circle 3.
The angle at the lower oblique angle 9 is 9 °, and the angle of the top rade 10 is 9 °, and the angle at the middle oblique angle 11 is 8 °,
9 ° are arranged to by lower oblique angle 9 and top rade 10, ensures that lower locating ring 1 can be synchronous in cooperating with upper locating ring 2
It is mobile, it is 8 ° by the way that middle oblique angle 11 is arranged to two oblique angles, thereby may be ensured that locating ring 2 and lower locating ring 1 can be perfect
