Abstract

The utility model relates to a rapid joint, comprising an inner connecting sleeve, an outer connecting sleeve and elastic sealing rings. The inner connecting sleeve and the outer connecting sleeve are made of the metal plate or the pipe in punching way. Meanwhile, the simple, reliable O-shaped, V-shaped, Y-shaped and U-shaped elastic sealing rings are adopted between the inner connecting sleeve and the outer connecting sleeve to be used as radial direction sealing elements. When the inner connecting sleeve separates from the outer connecting sleeve, the sealing elements are incidentally positioned in the outer connecting sleeve. The utility model has the advantages of simple structure, easy fabrication, low cost, easy assembly and disassembly, high reliability, small size and light weight. The rapid joint can be widely used for occasions that various flexible pipes need to be frequently disassembled, assembled, replaced and connected.

Description

Rapid joint

Rapid pipe joint of the present utility model relates to the Quick Connect Kit of pipeline, particularly relates to the coupling arrangement between a kind of flexible pipe.

The rapid pipe joint of prior art when adopting metallic material to make, is generally all adopted sand mold, and permanent mold casting or high pressure die casting form.Therefore all inevitably to pass through cutting, and since casting technique limit its wall thickness book too again, so the volume of rapid pipe joint is big, Heavy Weight, manufacturing process complexity, manufacture cycle are grown, feed consumption is many.

The purpose of this utility model is made and a kind ofly to be formed with sheet metal or tube stamping, has that volume is little, in light weight, materials consumption is few, low cost of manufacture, and sealing simultaneously is reliable, the rapid pipe joint of easy accessibility.

Fig. 1 is the embodiment of the utility model rapid pipe joint, and Fig. 2 is for connecing the structural drawing of cover (1) in the rapid pipe joint, and Fig. 3 is the structural drawing of the external cover (3) in the rapid pipe joint.

The structure of rapid pipe joint of the present utility model is: be made up of interior cover (1), external cover (3) and the elastic seal ring (2) of connecing.It is inside and outside to connect and applies mechanically sheet metal or tube stamping forms.On its end garden perisporium that is connected with flexible pipe, respectively there is one to three circle to prevent the flexible pipe slippage, extrude or outwards curling convex shoulder (7), (3) to external diameter by endoporus, in the interior joint that connects cover (1) and external cover (3), an O shape, V-arrangement, Y shape or U-shaped elastic seal ring (2) are arranged.Elastic seal ring (2) is made by rubber, plastics, leather or metal pipe.When connecing cover and separating, elastic seal ring (2) attaches in half garden shape groove (12) of external cover (3) when inside and outside.To connect socket fashionable when inside and outside, in connect cover (1) connects an end with external cover (3) conical convex shoulder (9) and enter in the elastic seal ring (2), and elastic seal ring (2) is carried out mild compression and forms sealing strip.In order to keep the inside and outside positive connection that connects when sealing cover, the axial force that overcomes liquid in pipe or gas pressure intensity simultaneously and produced, half garden shape groove the inside inwall of external cover (3) and in connect on the circumference (13) of the tapered convex shoulder of cover (1) (9) outside, respectively towards one to four interconnective flange of confession (10), (11) are arranged; The spacing of flange is that inside and outside flange (10), (11) that connect cover can axially be passed through mutually.Easy to connect in order to make, flange is by axially can be made into spirality.

When inside and outside when connecing cover and need connect, as long as in connect a end that cover (1) is shaped on taper convex shoulder (9) and be inserted into external cover (3) and be equipped with in the hole of elastic seal ring (2), and the flange (10) that connects cover (1) in making is inserted in flange (11) spacing of external cover (3), rotate an angle simultaneously, flange (11) back that the flange (10) that connects cover (1) in making rotates to external cover (3) gets final product (seeing accompanying drawing 1).

For the inside and outside cover that connects that makes rapid pipe joint can be used in when making with ferrous metal and has in corrosive liquid or the gas medium, can make at its surperficial coating one deck resistant material.

Snap joint of the present utility model has simple in structure, and low cost of manufacture, easy accessibility use the characteristics such as reliable that seal; Can be used in widely various dismounting frequently in the Moveable pipeline, be specially adapted to the connection of various flexible pipes.

The processing method of the utility model rapid pipe joint: its process route is when adopting sheet metal: divide three drawing sequences after the die-cut blanking, go out bottom outlet then, method processing convex shoulder (7) or (8) and taper convex shoulder (9) or half garden shape groove (12) with spinning, stamp out flange (10) or (11) at last, form by side cut or deburring again.As adopt metal pipe processing can omit drawing sequence three times, and die-cut blanking is changed into pipe cutting, all the other processing methods are identical with sheet material processing.

Claims
