The width of tee section, less than the radial distance between two fixture blocks；The greatest length radially of the edge point bar of boss, more than between two fixture blocks
Radial distance, and less than the internal diameter of groove；
Described cylindrical height, more than or equal to the axial height of fixture block；Cylindrical external diameter is less than the radial direction between two fixture blocks
Distance.
As the restriction to aforesaid way, described fixture block is provided with from inwardly in the axial direction spacing blind of point rod end surface
Hole；
Described anti-rotation device includes being located at point boom end the blind hole axially the most corresponding with spacing blind hole, is limited in blind hole
Spring, it is fixed on the Anti-rotary block of spring top, and is fixed on Anti-rotary block outer wall the driving lever extended outside point bar；
On the outer wall of point bar, the corresponding position, position with blind hole is provided with bar-shaped trough, and driving lever passes bar-shaped trough, and can be in bar-shaped trough on
Lower movement；
After adjacent two points of bar clampings, Anti-rotary block is limited in spacing blind hole.
Owing to have employed technique scheme, compared with prior art, acquired technological progress is the present invention:
First the boss of a point of bar is embedded when the present invention assembles in the groove of another point of bar, then two points of bars are revolved relatively
Turn so that it is in the outer face of boss of point bar fixture block that is overlapped on another point of bar inner face on, in rotary course, divide bar
Groove and the outer face of fixture block can contact with the Anti-rotary block of another point of bar, and then compression spring, make two points of bars to rotate smoothly,
Till Anti-rotary block enters spacing blind hole.During two points of bar dismountings, stir driving lever, drive Anti-rotary block compression spring, make Anti-rotary block
Depart from spacing blind hole, rotate two points of bars simultaneously, when two limits of the width with another point of bar rotating the boss to a point of bar
When the central point line direction of position blind hole is parallel, between two points of bars, there is no restriction relation, two points of bars can be departed from.
In sum, the present invention can Fast Installation, and be connected firmly, striven for the time for fire extinguishing.
The present invention is suitable as fire-fighting poker and is applied to fire-extinguishing location.

Detailed description of the invention
Embodiment 1
A kind of fire-fighting poker, structure as Figure 1-3, including about three point bars 1 connected, is wherein positioned at point bar topmost
The top of 1 is with gib head 2.
Dividing the structure of bar 1 as Figure 4-8, the bottom of point bar 1 is provided with sunk structure, and it is that the bottom surface by point bar 1 is along axle
To the groove 3 upwards caved in, with the fixture block 4 of two axially symmetric settings on the inwall of groove 3, its by point bar 1 bottom surface to
Upper extension also projects radially inwards, and each fixture block 4 is provided with spacing blind hole 5.
In, the top of lower two points of bars 1 be respectively equipped with projective structure, each projective structure includes being fixed on point bar 1 top
Cylinder 6, being fixed on the boss 7 at cylinder 6 top, cylinder 6, boss 7 are arranged with point bar 1 coaxial line.
Boss 7 is oblong block structure for radial section.The axial height of boss 7 is less than or equal to groove 3 top
To the vertical distance on fixture block 4 top, the width of long round section is less than the radial distance between two fixture blocks 4, along point bar 1
Long length is more than the radial distance between two fixture blocks 4 and the internal diameter less than groove 3.The height of cylinder 6 is more than or equal to fixture block 4
Axial height, external diameter is less than the radial distance between two fixture blocks 4.
Point bar 1 top is additionally provided with mutually rotate after preventing the clamping of adjacent two points of bars 1 anti-in the periphery of sunk structure
Rotary device, it include being located at point bar 1 top the blind hole 8 corresponding with spacing blind hole 5 position, the spring 9 being limited in blind hole 8,
It is fixed on the Anti-rotary block 10 at spring 9 top, and is fixed on Anti-rotary block 10 outer wall the driving lever 11 extended outside point bar 1.Divide bar 1
Outer wall be provided with bar-shaped trough 12 corresponding to the position of blind hole 8, driving lever 11, and can in bar-shaped trough 12 up and down through bar-shaped trough 12
Mobile.After the clamping of adjacent two points of bars 1, Anti-rotary block 10 is limited in spacing blind hole 5.
The assembling process of the present embodiment is as follows:
First the boss 7 of a point of bar 1 is embedded in the groove 3 of another point of bar 1 when two points of bars 1 assemble, then by two points of bars 1
Rotate against, make the bottom surface of the boss 7 of lower section point bar 1 be overlapped on top and divide on the end face of fixture block 4 of bar 1, in rotary course, on
The groove 3 of side point bar 1 and the bottom surface of fixture block 4 can divide the Anti-rotary block 10 of bar 1 to contact with lower section, and then compression spring 9, make two points of bars
1 can rotate smoothly, divide the spacing blind hole 5 dividing bar 1 above Anti-rotary block 10 entrance of bar 1 until lower section till.Two points of bars 1 are dismantled
Time, stir downwards the driving lever 11 of lower section point bar 1, drive Anti-rotary block 10 compression spring 9 to move downward, make above Anti-rotary block 10 disengaging
Divide the spacing blind hole 5 of bar 1, rotate two points of bars 1 simultaneously, when the width rotating the boss 7 dividing bar 1 to lower section divides bar with top
When the central point line direction of the two spacing blind holes 5 of 1 is parallel, between two points of bars 1, there is no restriction relation, two points of bars 1 can be taken off
From.
