Abstract

The present invention relates to a clamping device for pipe joints and flexible pipes of the pipe joints, particularly to a fire-protection interface and a clamp hoop thereof. The smooth outer circle part of a fixed fire-protection water band of a pipe joint of an original fire-protection interface is changed into a plurality of annular bands which are matched with a clamping device with a proper shape, wherein the shapes of the annular bands are disclosed in the specification, and the clamping device is formed by connecting a lock button, a handle, a hoop band and a safety device which can have modes of a rotary button, a button, an insertion button, etc. When needing to be clamped on the pipe joint of the fire-protection interface, the fire-protection water band can be tightly buttoned by only pressing the handle of the clamp hoop; in order to prevent accidental applied force from pulling the handle to open the clamp hoop, the end of the handle is tightly sealed by the safety device so as to reach the purpose of reliably clamping the fire-protection water band. The present invention has the advantages of rapid connection, convenient use and no need of any tools and can provide safeguards for fire fighters to efficiently extinguish fire.

Description

The clamp device of pipe joint and flexible pipe thereof

Technical field

The present invention relates to the clamp device of a kind of pipe joint and flexible pipe thereof, be particularly useful for Fire coupling and clamp device thereof.

Background technique

At present, known Fire coupling, what its pipe joint adopted is that cylindrical is level and smooth, port is the ring-type of projection slightly, the way of the fixedly water band of corresponding employing is: the one, and adopt and directly use the iron wire tying, it is so more firm to say according to the fire fighter, still, this way is not only time-consuming, and instruments such as iron wire and vice must be arranged at hand; The 2nd, adopt the flat hoop of band nut tensioning means, as if this method convenient, but during actual the use because high hydraulic pressure and often cause the water band from flat hoop, to come off, the instrument of must reusing screws, and delays fire-fighting and goes out opportunity of calamity, causes unnecessary property loss.

On January 28th, 1998 State Patent Office's notice of authorization a kind of " Fire coupling and clamp device thereof ", the patent No. " 96212243.2 ", his clamp device is for adopting taper locknut and built-in clamping ring structure, this structure is complicated, price is high, operation shows slightly slower, in case and locknut is loosening, also easily causes the water band to come off.

Summary of the invention

The clamp device that the purpose of this invention is to provide a kind of pipe joint and flexible pipe thereof, especially Fire coupling and clamp device thereof make it also can rapidly flexible pipe be clamped on the pipe joint even without other instruments, and safety firmly.

Technological scheme of the present invention is achieved in that at the cylindrical of pipe joint stationary flexible tube and smoothly locates, and changes system into the ring of several projectioies, the sectional shape of ring can be " ∩ " shape or " ∧ " or Or

Shape etc., the supporting clamp device of going up with the corresponding flexible pipe of ring of projection; The clamp device of this flexible pipe is made of snap close, handle, band and safty device.Snap close, handle and band are linked in sequence and form the hoop of sealing or open shape, safty device then are used to prevent to be subjected to when hoop is in clamped condition unexpected external force pulling and unclamp, thus the firm reliability of safety when guaranteeing the clamp device work of whole flexible pipe.When needs clamp flexible pipe on pipe joint, only need prior clamp device to be inserted in flexible pipe outward with flexible pipe, the two is inserted in pipe joint simultaneously, pulls the flexible pipe jamming handle then, makes it flexible pipe is clamped, and buckles safty device again and gets final product.Just flexible pipe tightly can be clamped on the interface tube by above several simple actions, reach purpose of the present invention.

Owing to adopt such scheme, both need not tool using, convenient and swift again, and safety and reliability ground is clipped in flexible pipe on the pipe joint tightly, concerning the fire fighter, can win more valuable flame extinction time, more stamp out a fire more in time soon.

Among the figure: 1, fire-fighting end interface; 2, pipe joint; 3, clamp device; 4, water band; 5, handle; 6, snap close; 7, band; 8, safty device

Embodiment:

In Fig. 1, Fig. 2, be a kind of enforcement phase diagram of fire-fighting end interface 1, pipe joint 2, clamp device 3, water band 4, by clamp device 3 water band 4 is clipped on the Fire coupling pipe joint 2 tightly.

In Fig. 3, Fig. 4, Fig. 5, be the pipe joint of three kinds of different cross section convex rings, according to actual conditions, the convex ring of many representative sections can also be arranged.

In Fig. 6, Fig. 7, Fig. 8, be various safty device, with several examples of configurations of open shape or enclosed shape clamp device and band.Among Fig. 6 be a kind of screw fastening type safty device wherein, the two edges of band are the adjustable clamping means of corrugated open, bulge loop cross section for " ∩ " shape; Among Fig. 7 is a kind of safty device of plug-snap type, the two edges of band be level and smooth shape, the bulge loop sectional shape is

The closed clamp device of shape, among Fig. 8 is a kind of button safty device, the two edges of band are that the cross section of level and smooth shape is The open adjustable clamping means of shape.In the product of reality, various safty device, open or seal clamp device, and the different shape of band can carry out combination in any, also comprise the combination in any that cooperates arbitrarily with the cross section of the convex ring of various pipe joints, thereby can derive the clamp device of many flexible pipes that are suitable for implementing, certain, the specific embodiment that those skilled in the art can also make more equivalences comes, and can be decorative pattern shape or the like as the two edges of band.

In Fig. 9, Figure 10 is two kinds of different modes of expression snap close, and what wherein Fig. 9 represented is facade " V " shape snap close, and Figure 10 is plane " ∪ " shape snap close.Plane, facade and " V ", " ∪ " shape and other shape can make up arbitrarily, make snap close produce the snap close of various different modes, but general strong than the plane of the self-lock ability of facade snap close.

What represent in Figure 11, Figure 12 is the part of a kind of spinner and the handle that cooperates with it thereof, the rotation spinner is 90 ° after the spinner as safty device enters from the hole 5b of Figure 12, two protruding points that make it spinner buckle in two holes of 5a, can reach the purpose of safe locking.

What represent in Figure 13 is the locking schematic diagram of another toggle formula safty device and handle, toggle 8 peripheral projections contract in when handle 5 is pressed and reply then, by its peripheral projection handle is blocked, in the time will pulling down, must the peripheral projections of button 8 be pressed to make in it and contract with external force, can open handle, thereby play the stop purpose of handle of safety lock.

It in Figure 14 a kind of eye-splice, be suitable for being disposed in the Flexible Fixturing device among Fig. 7, because two edges of projection have certain elasticity in the middle of it, after in the matching hole of eye-splice insertion handle and band, because of eye-splice broad in the middle, two is little, and not having certain external force is to be difficult to socket be extracted and handle is opened, thereby reaches the stop purpose of handle of safety lock.

Certainly, those skilled in the art necessarily also have more mode of execution like the multiclass, reach effects equivalent of the present invention, and the mode of execution of these effects equivalent also should be considered as within protection scope of the present invention.
