Specific implementation mode
The utility model is further elaborated in the following with reference to the drawings and specific embodiments.
As depicted in figs. 1 and 2, a kind of column DR central post rotary positioning structures double manually, including connecting plate 1, positioning disk
2, frame 3, foot-operated rotary shaft 4, position-limitting pin 5, foot-operated 6, a few type holders 7, spring 8, hollow pipe 9, copper sheathing 10, foot-operated fixed plate
11, sealing block 12, locating shaft 13, foot-operated mounting bracket 22, the positioning disk 2 on frame 3 are mounted with connecting plate by shaft connection
1, foot-operated 6 are fixedly mounted on by foot-operated rotary shaft 4 and position-limitting pin 5 in foot-operated mounting bracket 22, and a few type branch of 6 upper ends are ridden
It is mounted with that hollow pipe 9,9 internal diameter of hollow pipe cover spring-loaded 8 on frame 7,9 upper end of hollow pipe has been set with copper sheathing 10,10 upper end of copper sheathing
It is mounted with locating shaft 13, rides 12 stationary positioned axis 13 of fixed plate 11 and sealing block.
3 center of the frame is mounted with that live spindle 21 connects connecting plate 1 and positioning disk 2.
21 upper end of the live spindle has been set with upper taper roll bearing 15 and Upper shaft sleeve 14.
21 lower end of the live spindle has been set with lower taper roll bearing 19 and Lower shaft sleeve 20, and Lower shaft sleeve 20 is suitable from bottom to top
Sequence location and installation round nut 16, stop washer 17 and end ring 18.
Utility model works principle：The structure is mainly classified into following two parts in the utility model：1, rotating part
Point；2, position portion.
1, rotating part uses upper and lower two taper rolling bearings, and taper rolling bearing above is used for bearing column, X is put
Penetrate the weight such as bulb；Following taper rolls the rotary shaft for locking endurance, after can ensureing rotary shaft installation in this way
Gap, to solve the problems, such as column because that can be tilted by when cantilever force.
2, position portion lengthens copper sleeve and the lengthening locating rod of ball head and the positioning plate of taper, makes it accurate
Gapless when positioning and can guarantee positioning between locating rod and positioning plate, to ensure the Stability and veracity of positioning.
Since the utility model uses biconial rolling bearing, solve with front column because by can be inclined when cantilever force
Problem；In addition copper sleeve and the lengthening locating rod of ball head and the positioning plate of taper are lengthened because using, solves positioning
