Utility model content
This utility model provides a kind of pyller anti-theft device, to solve above-mentioned technical problem present in prior art.
For solving above-mentioned technical problem, this utility model provides a kind of pyller anti-theft device, including：First, second sleeve,
Connecting rod and anti-return nut；Wherein, described first sleeve is arranged on the door-plate of steel tower, and second sleeve is arranged on the cylinder of steel tower
On, described connecting rod runs through described first, second sleeve and forms hinge arrangement, described retaining with described first, second sleeve
Nut is fixed on the end of described connecting rod.
Preferably, described anti-return nut includes：Neck bush and the outer nut being set on described neck bush, wherein, institute
The inside stating outer nut offers arcuate groove, and the radial depth minus thread of this arcuate groove turns to and is gradually increased, described arcuate groove
Inside it is provided with ball, described neck bush is provided with the track mating with described arcuate groove.
Preferably, described arcuate groove and ball are respectively equipped with two groups.
Preferably, described neck bush and described connecting rod interference fit.
Preferably, described neck bush include the main part matching with outer nut and with rushing that main part integral type is connected
Pressure surface.
Preferably, described first sleeve is welded on described door-plate.
Preferably, described second sleeve is fixed by welding on described cylinder.
Preferably, described hinge arrangement be provided with one or more groups of.
Compared with prior art, this utility model has advantages below：
1st, only steal nut can be directly installed in connecting rod, improve anti-theft and the anti-creep performance of steel tower pyller, with
When avoid employing welding, punching screw thread equivalent damage measure, method is simple to be easy to promote；
2nd, construction technology is attractive in appearance；
3rd, reduce maintenance workload, reduce maintenance cost；
4th, need not be welded, save power supply for construction amount, save construction investment；
5th, antitheft coefficient is high, and maintenance cost is low.
Brief description
Fig. 1 is the structural representation of pyller anti-theft device in this utility model one specific embodiment；
Fig. 2 is that this utility model one specific embodiment stops to steal the structural representation of nut.
Specific embodiment
Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings to this
The specific embodiment of utility model is described in detail.It should be noted that, this utility model accompanying drawing is all in the form of simplifying
And all using non-accurately ratio, only in order to purpose that is convenient, lucidly aiding in illustrating this utility model embodiment.
As depicted in figs. 1 and 2, this utility model provides a kind of pyller anti-theft device, including：First 100, second set of sleeve
Cylinder 200, connecting rod 300 and anti-return nut 400；Wherein, described first sleeve 100 is arranged on the door-plate of steel tower, second sleeve
200 are arranged on the cylinder of steel tower, and described connecting rod 300 runs through described first, second sleeve 100,200, certainly, described
First, second sleeve 100,200 is on the same line, forms hinge arrangement with connecting rod 300, and then can ensure that pyller can
With normal folding, described anti-return nut 400 is fixed on the end of described connecting rod 300, and after preventing from installing, someone is by connecting rod
300 take out from first, second sleeve 100,200, dismantle door-plate.
Emphasis includes with reference to Fig. 2, described anti-return nut 400：Neck bush 410 and be set in outer on described neck bush 410
Nut 420, wherein, the inside of described outer nut 420 offers arcuate groove, and the radial depth of this arcuate groove turns in minus thread
On be gradually increased, be provided with ball in described arcuate groove, described neck bush 410 is provided with the track mating with described arcuate groove.
Specifically, described neck bush 410 and connecting rod 300 interference fit are so that anti-return nut 400 is fastened on described connecting rod 300
End, when screwing outer nut 420 clockwise, ball rolls along arc shaped groove, when unscrewing outer nut 420 counterclockwise, due to arc
The radial dimension of groove tapers into, and ball is stuck between outer nut 420 and neck bush 410 it is impossible to by outer nut 420 from liner
Take off, thus playing anti-theft function on set 410.
Preferably, described arcuate groove and ball are respectively equipped with two groups, can increase outer nut 420 and neck bush 410 it
Between effect, increase anti-theft effect.
With continued reference to Fig. 1 and Fig. 2, described neck bush 410 includes the main part matching with outer nut 420 and and main part
The stamping surface that integral type connects, in other words, the section of described neck bush 410 is convex, and its stamping surface is located at outside, for
Outer nut 420 coordinates, it is to avoid ball comes off.
Preferably, described first sleeve 100 is fixed by welding on described door-plate, described second sleeve 200 is passed through
