Description

The fire fighting fastener Quick Connect Kit

The utility model relates to the device that connects fast between a kind of fire fighting fastener.

Connect fast between the existing fire fighting fastener and be by making two buttons of preparing to connect that connect form that the male and female collocation realizes, its concrete structure is: be buckled with an end and be provided with screw thread female connecing, the coupling collar that has the attachment strap seat is installed in female connecing by screw thread and buckles, the attachment strap seat is to be contained in the annulus of circumferentially evenly offering breach in the coupling collar, takes just to collude to be installed on the gap position.Hero connects to link and connects the end retainer ring that one circle protrudes and the pushing circle that can move forward and backward are arranged, during butt joint hero connect button be inserted into female connect to be taken to catch in the coupling collar of buckling just can; The reach of pushing circle is pushed open to take just to collude and can be made the two disengagement.This connect fast button convenient with it, reliable, install and remove rapidly that performance is widely used at present in fire protection sector.But assemble very inconveniently this processing special charges man-hour that connects button, and manufacturing efficiency is low, so cost is very high.

It is a kind of easy to assembly that the purpose of this utility model just is to provide, and processes simple fire fighting fastener Quick Connect Kit

The purpose of this utility model is achieved in that it comprises that hero connects button and supporting with it being equipped with taken the female button that connects that colludes, coupling collar is fixedly connected on the female button body end that connects, circumferentially evenly offer the strip hole on the coupling collar ring wall, take to collude and be installed in the strip hole, there is guard ring to be close on the coupling collar outer wall outside the strip hole, colludes landing and seal action to play to prevent to take.Connect closely for male and female being connect link, on the coupling collar inwall, the strip hole connects between the button body with female, offers one and encloses fixed groove.

The utility model is used in existing fire-fighting and is connect on the basis of button fast, its modular construction is optimized design: because the existing fire product overwhelming majority is aluminum casting, therefore the basic skills of utilizing cast aluminium to process can make easily to optimize structure and be implemented.

The utility model is compared with existing fire fighting fastener Quick Connect Kit, it is keeping mounting or dismounting quick and convenient, on the firm safely advantage basis, integral casting forming reduces the gold machining surplus, therefore simple in structure, be easy to assembling, saved a large amount of man-hours and material, reduced cost of production effectively, and dimensionally stable, be applicable to as various forms of connecing such as pipe teeth and buckle.

Below by way of embodiments and drawings the utility model structure and use are further described.

Fig. 1 is a female buckle structure schematic representation that connects of embodiment,

Fig. 2 is the A-A sectional view of Fig. 1,

Fig. 3 takes to collude to be installed in the female schematic representation of buckling that connects,

Fig. 4 is that female, hero connects button assembling schematic representation,

Fig. 5 is the female buckle structure schematic representation that connects of another embodiment.

Among Fig. 1, Fig. 2, the female fixedly connected coupling collar 2 of an end that connects button body 1, coupling collar 2 wall thickness are greater than the female wall thickness that connects button body 1, circumferentially evenly offer three strip holes 3 of 120 ° of being separated by on the coupling collar, offering a circle on coupling collar 2 inwalls at strip hole 3 and the female fixed groove of detaining between the body 14 that connects.There is fixedly back-up ring 5 position of 3 place coupling collars, 2 outer walls in the strip hole.Fig. 1, structure shown in Figure 2 are passed through the once complete moulding of aluminum process, just can produce the complete female button that connects by assembling several parts simply.As shown in Figure 3, take and collude 6 and can outside connecting ring 2, directly install, take and collude 6 gib head and be exposed in the inner chamber of connecting ring 2, take and collude other parts and comprise that reed 7 is installed in the strip hole 3, strip hole 3 is outer to have guard ring 8 to be close on the coupling collar outer wall, colludes landing and seal action to play to prevent to take.

Among Fig. 4, hero connects button 10 and extend into female connecing in button 1 the connecting ring 2, and its end is taken colludes 6 and pin.13 are mounted in the seal ring in the fixed groove 4.Guard ring 8 is composited by metal layer 9 and rubber layer, and metal layer 7 directly contacts with connecting ring 2 outer walls.Whole guard ring 8 is within two back-up rings 5 of connecting ring 2 outer walls, slides with guard ring 8.The 11st, hero connects the retainer spring of button pushing circle 12.During disengagement, will push circle and push away before 12, and make to take that colluding contracts in 6 and just hero can be connect button and smash extraction from female connecing.

Fig. 5 is that the female button that connects connects the structural representation of button when being an embodiment with the pipe tooth.The 14th, the pipe tooth connects button, and the 2nd, the pipe tooth connects the connecting ring of button, and the 3rd, circumferential strip hole 3 uniformly on the coupling collar is taken and is colluded 6 and be installed in the strip hole 3, and the 4th, connect the fixed groove of detaining between the body 14 4 in strip hole 3 with the pipe tooth offering a circle on coupling collar 2 inwalls.Seal ring 13 is arranged in the fixed groove 4, and there is fixedly back-up ring 5 position of 3 place coupling collars, 2 outer walls in the strip hole.Guard ring 8 is fixed on and seals strip-type hole 3 in the back-up ring 5.

Claims (2)

1, fire fighting fastener Quick Connect Kit comprises that hero connects button (10) and supporting with it being equipped with taken the female button (1) that connects that colludes (6), it is characterized in that:

Coupling collar (2) is fixedly connected on female button body (1) end that connects, and circumferentially evenly offers strip hole (3) on coupling collar (2) ring wall, takes to collude (6) and be installed in the strip hole (3), and strip hole (3) are outer to have guard ring (8) to be close on coupling collar (2) outer wall.
