Description
Technical field
The present invention relates to fire-fighting equipment technical field, especially a kind of fire coupling structure.
Background technology
Fire coupling is fire-fighting system requisite fire-fighting accessory, and it is generally used for lengthening water band, and for water
Connection between band and fire hydrant, fire fighting truck and hydraulic giant, carries out the conveying of water body or the conveying of mixing liquid to put out a fire
Work.But, its interface bonding strength of present fire coupling is inadequate, easily occurs when pressure of supply water is bigger that disengage shows
As, have impact on the effect of fire extinguishing, and it connects inconvenience, operates relatively difficult.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of fire coupling structure, and it has interface bonding strength
High, interface is difficult to disengagement, the convenient feature of attended operation.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of fire coupling structure, including a cylindrical body, described main body one end is formed many to main center's extension
Individual draw-in groove, each draw-in groove side is provided with a claw, leaves an introducing port making way for claw, institute between draw-in groove and claw
Stating introducing port edges at two ends arc transition, described claw outwards bends and is formed with snap fit, and the main body other end is provided with connecting tube.
As the improvement of technique scheme, described draw-in groove is provided with three, between adjacent draw-in groove in 120 ° angle week cloth
In body port, described claw be correspondingly provided with three, each other in 120 ° angle week cloth at draw-in groove side.
Further, the two ends of described claw are 25 °～30 ° with the angle a of main center.
Further, described main body is positioned at claw root and is provided with the installation position for placing waterproof apron.
Further, described connecting tube outer wall is provided with connection screw thread.
Further, described claw is additionally provided with a breach relative to the opposite side of introducing port, and described gap width is less than claw
Width.
Further, described main body, draw-in groove, claw and connecting tube are one-body molded.
The invention has the beneficial effects as follows: the present invention is provided by a cylindrical body, main body one end is prolonged to main center
Stretching and be formed with multiple draw-in groove, each draw-in groove side is provided with a claw, leaves one and make way for claw between draw-in groove and claw
Introducing port, introducing port edges at two ends arc transition, claw outwards bends and is formed with snap fit, and the main body other end is provided with connection
Pipe, is respectively clamped in the draw-in groove of the other side by the claw of two fire couplings during use, thus realizes the company of two fire couplings
Connect, the most due to the quantity of draw-in groove and claw in the present invention, form multiple biting point so that the bonding strength of interface compares
Height, can bear the high hydraulic pressure of comparison and not disengage, and introducing port edges at two ends is arranged to arc transition so that using
Time, in that context it may be convenient to stretching into claw from introducing port to rotate in draw-in groove again and connect, operation is very easy, save operation time
Between, improve work efficiency.
Accompanying drawing explanation
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
With reference to Fig. 1, a kind of fire coupling structure, include a cylindrical body 1, main body 1 is in hollow form, and main body 1 is permissible
Using aluminium alloy or plastics or other materials to make, to main body 1 center, extension is formed with multiple draw-in groove 2, each card in main body 1 one end
Groove 2 side is provided with a claw 3, leaves an introducing port 4 making way for claw 3, introducing port 4 liang between draw-in groove 2 and claw 3
End margin arc transition, claw 3 outwards bends and is formed with snap fit, and main body 1 other end is provided with connecting tube 5, and passing through during use will
The claw 3 of two fire couplings is respectively clamped in the draw-in groove 2 of the other side, thus realizes the connection of two fire couplings, in the present invention
Owing to the quantity of draw-in groove 2 and claw 3 is the most, form multiple biting point so that the bonding strength of interface is higher, can bear
Compare the highest hydraulic pressure and do not disengage, and introducing port 4 edges at two ends is arranged to arc transition so that in use, can facilitate
Claw 3 is stretched into from introducing port 4 rotate again in draw-in groove 2 connect, operation is very easy, saves the time of operation, improve
Work efficiency.
In the present embodiment, draw-in groove 2 is preferably provided with three, between adjacent draw-in groove 2 in 120 ° angle week cloth at main body 1 port
On, claw 3 be correspondingly provided with three, each other in 120 ° angle week cloth at draw-in groove 2 side, it is, of course, also possible to select arrange
There is the draw-in groove 2 of four or five or above number, be provided by ratio greater number of draw-in groove 2 and claw 3 so that the company of interface
Connecing intensity higher, for easy to make and reduction cost, the present embodiment preferably draw-in groove 2 and claw 3 are respectively arranged with three, card
The two ends of pawl are 25 °～30 ° with the angle a of main center.Claw is facilitated to snap in draw-in groove.
For make interface when connecting tightr and water-tight, main body 1 is positioned at claw 3 root and is provided with for placing marine glue
The installation position 6 of circle, by placing waterproof apron on installation position 6 so that two interfaces can realize being tightly connected after connecting and
Water-tight, it is to avoid to leak when water delivery.
For convenience of connecting the external equipments such as water band, hydraulic giant, fire hydrant, connecting tube 5 outer wall can be provided by connecting spiral shell
Stricture of vagina or other structures, quickly can be connected this fire coupling structure with other equipment by connecting screw thread, improve operation just
Profit.
In the present invention, the opposite side of the relative introducing port 4 of claw 3 is additionally provided with a breach 7, and breach 7 width is less than claw 3
Width, is provided by breach 7, can be when carrying out the connection of two interfaces or getting loose, and rotatable interface can have both direction
The position adjusted, it is to avoid interface connected and is difficult to long afterwards rotate and cause and cannot deviate from toward a direction, improved the facility used
Property.
In order to easy to make, main body 1, draw-in groove 2, claw 3 and connecting tube 5 in the present invention are one-body molded.
The above, the simply better embodiment of the present invention, but the present invention is not limited to above-described embodiment, as long as
It reaches the technique effect of the present invention with any same or similar means, all should fall under the scope of the present invention.
