Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in further detail.
Billboard and banner manually from screw device, including lower locating rod 6, lower four-way part 5, upper locating rod 4, upper four-way part 3,
Sheer pole 2, cross tube 1;The cross tube 1 and the level of sheer pole 2 and interval setting;The two ends of cross tube 1 are inserted in four
Logical part 3;The two ends of sheer pole 2 are inserted in lower four-way part 5;The upper four-way part 3 of the top of upper locating rod 4 connection, bottom connection
Lower four-way part 5;The lower four-way part 5 of the top of lower locating rod 6 connection, bottom is installed with self-tap 14;The self-tap 14
Bottom is provided with guiding wedge angle;The upper locating rod 4, lower locating rod 6 and self-tap 14 are coaxially disposed.
The present apparatus, is drawn by sheer pole 2, the fixation of advertisement of cross tube 1, plays a part of preventing advertisement poster from letting it flow.This
Device all parts, it is easy to assemble and disassemble, it is recyclable to recycle, also, it is applicable scene extensively, the lower hand of locating rod 6 is screwed in burying,
The present apparatus can just be fixed.
The upper four-way part 3 and lower four-way part 5 include being integrally formed and in the upper branch pipe 8 of hollow cylindrical, lower branch
Pipe 9, left branch pipe 10 and right branch pipe 11;The upper branch pipe 8, lower branch line 9 it is coaxial and it is isometrical set;The left branch pipe 10 and right branch pipe
11 coaxial and isometrical settings.
The upper branch pipe 8 and lower branch line 9 are provided with internal thread;The top of upper locating rod 4 and the lower branch of upper four-way part 3
Pipe 9 is threadedly coupled, and bottom is threadedly coupled with the upper branch pipe 8 of lower four-way part 5;Under the top of lower locating rod 6 and lower four-way part 5
Branch pipe 9 is threadedly coupled.
The two ends of cross tube 1 and the two ends of sheer pole 2 offer inner via hole 12 and accessibke porosity 13;The He of inner via hole 12
Accessibke porosity 13 is inserted with locating rod 7;The spacing of the inner via hole 12 and accessibke porosity 13 is slightly larger than the left left side of branch pipe 10 and right branch pipe
The spacing on 11 right sides.
The locating rod 7 takes the shape of the letter U.Locating rod 7 is arranged in inner via hole 12 and accessibke porosity 13, positioning branch pipe and four-way is played
The effect of part.
The length of the self-tap 14 is at least the half of the lower length of locating rod 6, and self-tap 14 can be come by the hardness of soil
Adjustment is screwed into soil enough depth, and the fixation degree for being screwed into the deeper present apparatus of soil is just more firm.
