So not readily portable, when storage, also relatively takes up space.
Utility model content
In view of the defects of above-mentioned prior art, the purpose of this utility model is that：A kind of easy disassembly and storage are provided
Drainage pipeline conserves O＆M safety device.
The technical solution of the utility model is：A kind of drainage pipeline conserves O＆M safety device, described including stent
Stent is made of multiple stocks, middle bar, quarter butt, the first connector, the splicing of the second connector, and first connector and the second connector are
Three-way connection, each first connector are sleeved on the centre position of stock, and the equal grafting in side two of each first connector is vertically set
The middle bar put, each second connector and a stock top grafting, the equal grafting in outside two of each second connector are mutually perpendicular to set
The quarter butt put；The bottom end of the stent has been removably installed fixed band.
Further, the quantity of the fixed band is four, and every fixed band is removably disposed in adjacent two stock
Between.
Further, the both ends of the fixed band are respectively equipped with fixed ball, and stock is equipped with the fixation with fixed ball cooperation
Slot.
Further, the fixed strap end portion is equipped with bayonet section, the opening of the fixing groove at fixed ball position
With the big hole, square hole and small sircle hole being sequentially connected from top to bottom, the outer diameter of the fixed ball be more than the diameter of small sircle hole and
Direct less than big hole, the square hole is caught in for bayonet section, and the fixed ball is caught in fixing groove, and bayonet section is from big hole
Slide to small sircle hole.
Using a kind of drainage pipeline maintenance O＆M safety device provided by the utility model, advantage is：Stent
It is made of multiple stocks, middle bar, quarter butt, the first connector, the splicing of the second connector, is convenient for carrying and stores after dismounting；The bottom of stent
End has been removably installed fixed band, and fixed band can play the role of rigid support, and fixation band may be used can play police
The belt being shown as, plays warning effect.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the scheme of installation that band is fixed in a-quadrant in Fig. 1.
Shown in figure：100-stent, 1-stock, 2-middle bar, 3-quarter butt, the 4-the first connector, the 5-the second connector,
6-fixation band, 61-fixation ball, 62-bayonet section, 7-fixing groove, 8-big hole, 9-square hole, 10-small sircle hole.
Specific embodiment
For it is relatively intuitive, be fully understood by the technical solution of the utility model, now just combine the progress of the utility model attached drawing
Unrestricted feature description is as follows：
As depicted in figs. 1 and 2, a kind of drainage pipeline maintenance O＆M safety device, including stent 100, stent 100 is by multiple
Stock 1, middle bar 2, quarter butt 3, the first connector 4, the second connector 5 splicing composition, the first connector 4 and the second connector 5 are three to connect
Head, each first connector 4 are sleeved on the centre position of stock 1, and the equal grafting in side two of each first connector 4 is vertically disposed
Middle bar 2, each second connector, 5 and one stock, 1 top grafting, the equal grafting in outside two of each second connector 5 are mutually perpendicular to set
The quarter butt 3 put；The bottom end of stent 100 has been removably installed fixed band 6.
The quantity of fixed band 6 is four, and every fixed band 6 is removably disposed between adjacent two stock 1.
The both ends of fixed band 6 are respectively equipped with fixed ball 61, and stock 1 is equipped with the fixing groove 7 coordinated with fixed ball 61.
Fixed 6 end of band is equipped with bayonet section 62 at fixed 61 position of ball, and 62 outer diameter of bayonet section is than fixed 6 outer diameter of band
Small, the opening of fixing groove 7 has the big hole 8, square hole 9 and the small sircle hole 10 that are sequentially connected from top to bottom, and 6 outer diameter of fixed band is big
In 9 width of square hole, the outer diameter of fixed ball 61 is more than the diameter of small sircle hole 10 and is less than the direct of big hole 8, and square hole 9 supplies bayonet section
62 are caught in, and the fixed ball 61 is caught in fixing groove 7, and bayonet section 62 slides to small sircle hole 10 from big hole 8.At this point, fixed ball
61 are located at 10 lower section of small sircle hole, because the outer diameter of fixed ball 61 is more than the outer diameter of small sircle hole 10, fixed ball 61 will not be from small sircle hole
10 that skid off, need will fixed ball 61 when removing, pinch fixed 6 end of band and be lifted up, fixed ball 61 slides to big hole 8
At position, then fixed ball 61 is pulled outward and fixed ball 61 can just be removed, the fixation ball 61 at fixed 6 both ends of band all removes
Afterwards, fixed band 6 just completes dismounting.
A kind of drainage pipeline maintenance O＆M safety device provided by the utility model, stent 100 by multiple stocks 1, in
Bar 2, quarter butt 3, the first connector 4, the second connector 5 splicing composition, are convenient for carrying and store after dismounting；The bottom end of stent 100 is removable
Fixed band 6 is installed with unloading, fixed band 6 can play the role of rigid support 100, and fixed band 6 may be used can play police
The belt being shown as, plays warning effect.
Certainly, the above is only the preferred embodiments of the present utility model only, and therefore, it does not limit the patents of the utility model
Range, all with the utility model specification and schema content institute, simply modification and equivalent structure change for it, should all similarly wrap
Within scope of patent protection contained in the utility model.
