21 ends of seat make to be made expansion set drive rod 4 and positioning expansion set 3 with interior bar by thrust at the rear stopper 43 of expansion set drive rod 4 by compression spring 5
2 are promoted, and realize the length reduction for making curtain rod in 2 retraction outer bar 1 of interior bar.
（2）When needing to extend the length of curtain rod, outer bar 1 or interior bar 2 can be individually pulled, can also outer bar 1 and interior bar 2
Pull at the same time；Outer bar 1 is pulled, outer bar 1 is moved along interior bar 2 makes interior bar 2 pull out outer bar 1；When pulling interior bar 2, interior bar 2 is by mounting base
The edge of 21 bar shaped socket 212 makes the vertical plug of expansion set actuator 4 expansion set actuator 4 is drawn with interior bar 2 by pulling force
It is dynamic, realize that interior bar 2 pulls out outer bar 1 and elongates the length of curtain rod.
After operation two, the length adjustment of the curtain rod of the present embodiment are good, the outer wall of positioning expansion set 3 and outer bar 1 is interior at this time
Wall is in the light contact condition for having friction, rotates interior bar 2 and/or outer bar 1, interior bar 2 is coupled with 1 clamping of outer bar.Specifically：Such as
Shown in Fig. 7, when rotating interior bar 2 and/or outer bar 1 relatively rotates outer bar 1 and interior bar 2, interior bar 2 by mounting base 21 bar shaped socket
212 edge makes the vertical plug stress of expansion set actuator 4, expansion set actuator 4 is rotate in same direction with interior bar 2, in light contact production
Under raw slight frictional force effect, positioning expansion set 3 rotates in same direction with outer bar 1, makes the circular cone of positioning expansion set 3 and expansion set actuator 4
Shape bar 42 relatively rotates, while conical rod 42 makes 31 distending of distending mouth of positioning expansion set 3, realizes that positioning expansion set 3 is driven by expansion set
The small end movement of the conical rod 42 of moving part 4 finally realizes expansion set actuator to the big end of the conical rod 42 of expansion set actuator 4
4 conical rod 42 makes the outer wall of positioning expansion set 3 compress the inner wall to outer bar 1 by expansion set 3 is positioned from 31 distending of distending mouth, makes interior
Bar 2 couples with 1 clamping of outer bar, plays the role of the length of fixed curtain rod.
For fixing the curtain rod of length, it is necessary to when adjusting length again, using the side opposite with above-mentioned rotation direction
To rotating interior bar 2 and/or outer bar 1 relatively rotates outer bar 1 and interior bar 2, makes the cone of positioning expansion set 3 and expansion set actuator 4
Bar 42 relatively rotates, while conical rod 42 reduces the distending mouth 31 of positioning expansion set 3, realizes that positioning expansion set 3 is driven by expansion set
The big end movement of the conical rod 42 of part 4 to the small end of the conical rod 42 of expansion set actuator 4, make the outer wall of positioning expansion set 3 with
The inner wall of outer bar 1 returns to the light contact condition of friction（As shown in Figure 6）, then the length of curtain rod is carried out by the way of operation one
Degree adjustment.
Three are operated, after the length of the curtain rod of the utility model fixes, as shown in figure 8, slightly enforcing interior bar 2
And/or outer bar 1 makes opposite compression, the mounting base 21 of interior bar 2 between interior bar 2 and outer bar 1 press to one end of compression spring 5, outer bar 1 passes through
It, which compresses the positioning expansion set 3 of connection, makes expansion set actuator 4 be moved with outer bar 1, the rear stopper 43 of expansion set actuator 4 is pressed to compression spring
5 other end, since the vertical plug of expansion set actuator 4 can move in the bar shaped socket 212 of the mounting base 21 of interior bar 2, makes
In the 44 retraction interior bar 2 of cylindrical bar of expansion set actuator 4, the mounting base 21 of interior bar 2 and the rear stopper 43 of expansion set actuator 4 are distinguished
Pressing to the both ends of compression spring 5 makes the compression of compression spring 5 store power, while makes the length reduction of curtain rod to the side walls for being slightly less than window
Curtain rod, is then placed in the setting height(from bottom) between the side walls of window by spacing, eliminates thrust, and compression spring 5 discharges elastic force point
The rear stopper 43 of the mounting base 21 and expansion set actuator 4 to interior bar 2 is not pushed up, makes interior bar 2 and outer bar 1 by elastic force, makes interior bar 2 and outer
The end socket seat 8 of bar 1 is compressed in the side walls of window respectively, consolidates curtain rod by the frictional force between end socket seat 8 and wall
Dingan County is loaded on window.
The curtain pole structure of the present embodiment is simple, assembling is quick and convenient, has what can freely be adjusted length and be easily installed
Feature.
