Description
Technical field
The present invention relates to fire-protection equipment field, particularly relate to having and press-fit the fire-extinguisher water hose that connects button.
Background technique
Fire-extinguisher water hose is conventional extinguisher, under a lot of occasions of existing fire-extinguisher water hose, by fire hose coupler, connects use, and fire hose coupler must be firmly reliable with being connected of fire-extinguisher water hose, and during use, fire fighting fastener definitely can not come off from fire-extinguisher water hose.Generally at fire-extinguisher water hose, tightening the method that connects fire fighting fastener is to adopt iron wire or anchor ear as fastening piece, adopt in this way and tighten connection fire fighting fastener at fire-extinguisher water hose, when fastening, need manual operations, labor intensity is large, manufacturing efficiency is not high, fastening quality is unreliable, and the deficiency such as easily come off.In addition, use traditional method to tighten connection fire fighting fastener at fire-extinguisher water hose, tensile strength between its fire-extinguisher water hose and fire fighting fastener is difficult to reach the requirement of operations involving high pressure, high-lift operation, particularly iron wire or anchor ear can corrosions after permanent in the time, affect the soundness that fire-extinguisher water hose is connected with fire fighting fastener.
Summary of the invention
For addressing the above problem, the present invention proposes a kind of have press-fit the fire-extinguisher water hose that connects button, it can guarantee fire-extinguisher water hose belt body and fire fighting fastener fastening quality reliable, fastening simple to operate, quick, the manufacturing efficiency of fire-extinguisher water hose is high, and long service life.
The object of the present invention is achieved like this: a kind of have press-fit the fire-extinguisher water hose that connects button, comprise water band belt body and fire fighting fastener, water band belt body two is connected with fire fighting fastener, described water band belt body and fire fighting fastener are fastening by clamping sleeve pressing, the inner periphery of described clamping sleeve is provided with groove, described clamping sleeve by mould and fire fighting fastener pressing fastening after, at the outer surface of clamping sleeve, produce the reinforcement convex tendon perpendicular to end face.Specifically first clamping sleeve is inserted in from one end of water band belt body, follow the termination point casing of this end of water band belt body on the water band socket of fire fighting fastener, again clamping sleeve is moved and is placed in water band socket circumferential position to fire-extinguisher water hose termination, then by a kind of machinery of lateral extrusion power that provides, the circumference of clamping sleeve is exerted pressure and carried out pressing, make clamping sleeve produce plastic deformation, clamping sleeve and water band socket tabling, thus water band belt body is fastened on the water band socket of fire fighting fastener.
Further, described fire fighting fastener is comprised of water band socket, water band jump ring and water band overcoat, water band jump ring is used for fixing water band socket and water band overcoat, described water band socket is provided with the fastening bulge loop matching with groove on described clamping sleeve, by clamping sleeve inboard groove, tighten coordinating of bulge loop with water band socket, can improve the fastening quality between water band belt body and water band socket, anti-waterstop belt body at work slippage comes off.
Further, be hydrous water band jump ring fastening water band socket and water band overcoat, on described water band socket, be provided with jump-ring slot, for coordinating clamping sleeve, on described water band socket, be provided with binding groove.
Further, described clamping sleeve is provided with convex shoulder in the one end near water band strap head, and described convex shoulder tightens groove with water band socket and matches, and prevents that clamping sleeve from slippage occurring at work, in order to make convex shoulder inside clamping sleeve embed binding groove, described binding groove width is greater than clamping sleeve convex shoulder thickness.
Further, the wall thickness between the inside and outside cylndrical surface of described clamping sleeve is 3 ~ 5 millimeters.
Further, described clamping sleeve inner side is provided with 1 ~ 5 described groove.
Further, described reinforcement convex tendon is uniformly distributed on described clamping sleeve.
The invention has the beneficial effects as follows: the present invention compares with the method that adopts anchor ear or iron wire to be fastenedly connected fire fighting fastener on existing fire-extinguisher water hose, have when being fastenedly connected fire fighting fastener without manual operations, labor intensity is little, and manufacturing efficiency is high, fastening quality is reliable, the advantage of difficult drop-off during use.Greatly reduce and occur puncturing water band, the possibility that the faults such as fastening piece fatigue fracture occur, longer service life, has reduced the cost of production of fire-extinguisher water hose.By method of the present invention, at fire-extinguisher water hose, tighten connection fire fighting fastener, between its fire-extinguisher water hose and fire fighting fastener, fastening quality is reliable, tensile strength can reach the requirement of operations involving high pressure, high-lift operation, for fire-fighting work, particularly to the fire-fighting work of tall building, provide quality assurance, the present invention is particularly suitable for producing producer's use of fire-fighting equipment.
