The corresponding position of small-sized circular hole 27 is equally provided with warning groove, screw 28 has been attached across small-sized circular hole 27, by straight
Angle triangular plate 21 is inserted into vertical cylinder groove 19, increases the forced area of 18 bottom of stationary cylinder, while according to triangle
There is shape stability to considerably increase the firm of stationary cylinder 18, pass through the cylinder fixed thread 25 on cylindrical 24 top of quarter butt
It can be attached with the movable circular hole 26 at position among 23 bottom of L shape fixinig plate, it can be by L shape fixinig plate by screw 28
23 are fixed with warning 1 side surface of bottom plate, and the smooth neonychium 20 in vertical cylinder groove 19 can guarantee right angle trigonometry piece
21 are conveniently put into or take out, and the strip-shaped baffle 22 on 21 top of right angle trigonometry piece can guarantee that right angle trigonometry piece 21 is vertical in humiliation
It will not leak down when 19 inside of cylindrical groove, stability that is easy to disassemble and install while also substantially increasing device.
In the present apparatus, warning, which holds the bar shaped in box device, which places groove 6, can place support round bar 14, U-shaped fixed frame
15, the components such as bolt 17, support it is rectangular place groove 8 can place the warning stationary cylinder 18 warned in fixed device,
The components such as right angle trigonometry piece 21, L shape fixinig plate 23, two rectangular slabs, which are placed, can place foldable warning panel dress in groove 7
Components and the illumination and warnings such as left side segmental support 29, right side segmental support 29, left side display board 40 and right side display board 41 in setting
Two illumination and warning fixinig plates 45 in mechanism, the illumination components such as round frame 47 and headlamp 48, in illumination and warning mechanism
Two illumination and warning fixinig plates 45 can be mounted on the top of left side segmental support 29, and headlamp 48 is able to carry out illumination and prompt,
Device is facilitated to be prompted in rainy weather and at night.
Working principle: assembling warns fixed device first, takes out warning stationary cylinder 18 and right angle from warning holding box 3
Right angle trigonometry piece 21 is inserted into the vertical cylinder groove 19 of warning 18 side surface of stationary cylinder by triangular plate 21 in turn later
Portion, since smooth neonychium 20 facilitates right angle trigonometry piece 21 to be inserted into, the top with hour angle triangular plate 21 has strip-shaped baffle 22 can
Protection right angle trigonometry piece 21 is not fallen out, and after the installation is completed, takes out 23 for the movable circular hole 26 of lower part and warning stationary cylinder
The cylindrical quarter butt 24 on 18 tops carries out rotation connection by cylinder fixed thread 25, by the fixed device of assembled warning and police
Show that the side of bottom plate 1 is attached, by screw 28 pass through small-sized circular hole 27 and warning groove come to warn fixed device and
Warning bottom plate 1 is fixedly connected.
Secondly assembling installation support frame device and foldable warning panel assembly take out two branch inside warning holding box 3
Hold round bar 14, the lower part of two support round bars 14 be carved with installation screw thread 13 can with the installation screw thread 13 inside circular groove 2 into
Two support round bars 14 are fixed at left and right sides of the top of warning bottom plate 1, take out left side segmental support 29 later by the connection of row spiral
With right side segmental support 29, left side display board 40 and right side display board 41, left side display board 40 is crossed into putting in the segmental support 29 of left side
It sets groove 30 to be loaded in the segmental support 29 of left side, right side display board 41 is loaded by the placement groove 30 in right side segmental support 29
In right side segmental support 29, connection side by side after this two parts assembles, worker needs that sliding shoe 33 is pulled to move right at this time
Connecting bolt 34 is filled in into the position between upper and lower two arc fixed plates 38, due to distinguishing on upper and lower two arc fixed plates 38
There are two springs 37, and spring 37 is for relaxation state between connecting bolt 34 does not enter into, after connecting bolt 34 enters
Spring 37 is compressed, since spring can generate elastic force to generate opposite power, to ensure that arc fixed plate 38 by compression
It can be press-connected bolt 34, to ensure that left side segmental support 29 is stably connected with right side segmental support 29.
Illumination and warning mechanism is finally installed, two illumination and warning fixinig plates 45 are taken out inside warning holding box 3, two
It is connected with brute spring 46 between illumination and warning fixinig plate 45, two illumination and warning fixinig plates 45 are loaded on left side segmental support 29
Top, due to the distance between two illumination and warning fixinig plates 45 become larger can tensile strength spring 46, brute spring 46 can produce
Raw powerful pulling force to ensure that two illumination and warning fixinig plates 45 can be stably mounted to the top of left side segmental support 29, it
Switch 51 need to be only opened afterwards can open headlamp 48 illuminated.
In manual mobile sliding shoe 33 in order to ensure that sliding shoe 33 can be inside slideway groove 32 without departing from slideway
Groove 32 is attached sliding shoe 33 by manual telescopic bar 39.
Only LED display 43, which need to be powered, at rainy weather perhaps night will show " hot work in progress " or " pay attention to
Evacuation " etc. has suggestive word to remind pedestrian, while opening headlamp 48 by opening switch 51 to remind pedestrian.
Fine day or daytime when, headlamp 48 can not be installed, can also be not turned on 43 need of LED display will have
The iron plate of logo role is attached on the display board 40 of left side and reminds pedestrian, can also have logo role by patch simultaneously
Iron plate reminds pedestrian with LED display 43 is opened.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
