Description
Technical field
The present invention relates to the building of special purpose, and in particular to a kind of flagpole, the flagpole can change the height of shaft.
Background technology
Flagpole is a kind of for factories and miness, enterprises and institutions, residence district, station, customs wharf, school, stadiums, height
The places such as level hotel, city square, the device established as a kind of mark.And the flagpole that these places are established often compares
Height, even more than 20 meters for having, such flagpole is often wasted time and energy when mounted, or even needs to use hoisting and hanging machinery.
Also, keep in repair when parts damages such as the pulley of truck, spherical crowns and be inconvenient, the personnel of needing repairing climb to truck dimension
Repair, it is very unfavorable to the life safety of maintenance personal.Additionally, installing in some places for periodically or non-periodically holding flagraising activity
Obviously other purposes in the place can be affected after flagpole, for example, installing flagpole in the playground central authorities of school can affect the body of student
Educate activity.
For the problems referred to above, insider proposes many solutions, and e.g., Authorization Notice No. is CN203160806U
Utility application disclosed in a kind of " Telescopic flagstaff ", the Telescopic flagstaff is made up of at least four sections straight-bars, per adjacent two
It is together by a threaded connection between section straight-bar；But when flagpole is higher, this Telescopic flagstaff then needs first to connect to set again
Erect and, however it remains the shortcoming of installation difficulty.Additionally, this flagpole is as common flagpole, still can't do without rising what is lowered flag
Pulley system.
For another example, Authorization Notice No. a kind of " fluid automatic controlling system disclosed in the utility application of CN2833009Y
Lifting flagpole ", the flagpole is substantially a kind of Telescopic oil tank, it can by into oil cylinder inject fluid come realize rise
Flagpole, but, this Telescopic oil tank belongs to a kind of one-way cylinder, can only be returned using the deadweight of the piston body of rod (see
The description of its specification paragragh second from the bottom), and when the frictional force between piston rod and end cap seal part is larger, be then difficult
The even uncontrollable speed that it is retracted.As can be seen here, the utility model still also needs to the pulley system that a set of liter is lowered flag, no
Then cannot as needed control the speed lowered flag.Additionally, also there are following deficiencies in the utility model patent：1st, due to this
Flagpole uses Telescopic oil tank, and its cost is highly unprecedented soaring with flagpole, and domestic consumer is difficult to bear；2nd, hydraulic pressure system
System is higher to seal request, and seal is easily damaged, and this causes the maintenance cost of this flagpole higher.
The content of the invention
The technical problem to be solved is to provide a kind of telescopic flagpole, and the flagpole can not only be omitted to rise and lowered flag
Pulley system, and both can control the speed hoisted a flag, the speed lowered flag is can control again.
The present invention solves the technical scheme of above-mentioned technical problem,
A kind of telescopic flagpole, it is characterised in that the flagpole includes telescopic bar, driving means and Thin Elastic steel
Band, wherein,
Described driving means have a casing, and vertical guide rail is provided with it, and the right opposite of the guide rail is provided with Chain conveyer
System, wherein, described chain drive system by constituting in two sprocket wheels being distributed up and down and across the chain being wound on two sprocket wheels, wherein
The chain is provided with one in the middle part of the one side and the guide rail parallel, and each outer plate lateral surface of the chain just to guide rail
Columnar projections；Described guide rail is just being the concave surface of arc to the face of the chain drive system side, the both sides of the concave surface from lower and
It is provided with two parallel grooves matched with the columnar projections, the outer plate on the distance of the groove and the chain both sides
The distance between upper set columnar projections are equal；
The cross section of described elastic thin steel strip is the arc matched with the concave surface on the guide rail, and along its length
The uniform through hole matched with the columnar projections of two rows is provided with, the line-spacing of the two rows through hole is equal to the chain both sides
The distance between set columnar projections on outer plate, and the distance per the adjacent two through hole of a line is equal on the chain adjacent two
The distance between set columnar projections on outer plate；
Described telescopic bar is worn by the sleeve pipe that one group of diameter is not waited and constitute together, wherein, per casing joint
Lower end be provided with the shrouding that diameter matches with the internal diameter of adjacent lower casing joint, shape is provided with the middle part of the shrouding with the bullet
Property the thin steel strip cross section arcuate socket that matches, when described telescopic bar is in contraction state, the envelope of all sleeve pipes
The contour convergence of the arcuate socket on plate；In addition to the casing joint of the top, the inside crimping in upper end per casing joint, the crimping institute
The aperture of formation matches with the external diameter of adjacent upper casing joint；
The lower end of described telescopic bar casing joint bottom is fixed on the upper of the casing of the driving means
Portion, the guide rail is extended down on the concave surface of the arc on the lower surface for stretching its shrouding, and the guide rail and its shrouding from casing
The outer side edges of arcuate socket profile overlap；Described elastic thin steel strip is located at the post between the guide rail and chain, on the chain
The raised through hole with elastic thin steel strip of shape is engaged, and elastic thin steel strip is squeezed on the guide rail；The elastic thin steel strip
Upper end extends in telescopic bar the top casing joint and is secured to together.
Because the telescopic bar in flagpole of the present invention is flexible therefore telescopic by the control of elastic thin steel strip
Expansion link is higher, and required elastic thin steel strip is longer.It can be seen that when elastic thin steel strip is longer, limited space obviously can in casing
Affect the normal work of flagpole.In order to solve an above-mentioned difficult problem, an improvement project of the present invention is that described box house also sets
There is helical form guide plate of the elastic thin steel strip of guiding in box house being collected in winding manner, the helical form guide plate is located at of outside spiral
Extend to the concave surface bottom of the guide rail, and start to upwarp to tangent in chain drive system bottom.
Another improvement project of telescopic flagpole of the present invention is, the top for most going up a section of described telescopic bar
End is provided with spherical crown, to improve decorative effect.
In order to allow flagraising person also to experience the impression of flagraising ceremony, flagpole of the present invention also can be in a section set topmost
Install additional at the top of pipe and rise the pulley system lowered flag, bottom casing joint is provided with around rope support.
Because the telescopic bar in flagpole of the present invention is flexible by the control of elastic thin steel strip, therefore omitting
In the case of rising the pulley system lowered flag, the speed hoisted a flag also both was can control, the speed lowered flag had been can control again.Additionally, the present invention is also
There is simple structure, low cost, life-span length and maintenance is easily installed.
