Embodiment 1

[0038] refer to figure 1 As shown, it is a scattered view of the main structure of the first embodiment of the pipe-rod connecting device that can be repeatedly installed and disassembled without loss. As shown in the figure, the pipe-rod connecting device in this embodiment includes a connecting pipe fitting 1, a A tapered sealing ring 2 , a tapered elastic ring 3 and a fastening nut 4 .

[0039] One end of the connecting pipe 1 is provided with an external thread, and an annular tapered surface 11 is provided inside it for arranging the tapered sealing ring 2; the other end of the connecting pipe 1 can be configured in the same way, or can be used for other purposes. In this embodiment, the connecting pipe 1 is made of metal material, but it is not limited thereto.

[0040] The main structure of the tapered sealing ring 2 is a sealing ring with a taper on the outer edge, and its taper is similar to that of the annular tapered surface 11. When in use, the tapered end of the ...

Embodiment 2

[0047] refer to Figure 5 Shown is the left side view of the second tapered elastic ring of the embodiment of the pipe-rod connection device that can be repeatedly installed and disassembled without loss in the present invention. As shown in the figure, the basic structure and components of this embodiment are the same as those of the first embodiment above, the difference is that the tapered elastic ring 3 is only provided with three front notches 33 and three rear notches 34 .

[0048] In this embodiment, the opening width of the front notch 33 and the rear notch 34 is 1 mm, and the slope of the outer surface of the tapered elastic ring 3 is 18 degrees, which is made of corrosion-resistant metal material It is suitable for the connection of small and medium-sized pipes and rods.

[0049] In this way, the setting of the front and rear slots of the tapered elastic ring 3 makes the deformation amount more balanced and more uniform when the pipe rod is connected, thereby grasp...

Embodiment 3

[0051] refer to Image 6 As shown, it is the front view of the three-tapered elastic ring of the embodiment of the pipe-rod connection device that can be repeatedly installed and disassembled without loss in the present invention. As shown in the figure, the basic structure and components of this embodiment are the same as those of the first embodiment above. , the difference is that the bottom of the front notch 33 and the rear notch 34 are circular, so that the deformation is more balanced in the compressed state, and the impact on the pipe rod 6 is Force gripping point area is larger.

[0052] In this embodiment, the tapered elastic ring 3 is provided with 8 front notches 33 and 8 rear notches 34, the width of the notches is more than 1mm, and the outer surface of the tapered elastic ring 3 is inclined The degree is 8 degrees. It is made of corrosion-resistant metal materials and is suitable for the connection of various pipes and rods, large, medium and small.

Abstract

The invention discloses a pipe rod connecting device capable of being repeatedly mounted and demounted without losses. The pipe rod connecting device comprises a connecting pipe fitting, a taper sealing ring and a taper elastic ring, an outer thread is arranged on the outer portion of one end, for connecting, of the connecting pipe fitting, and an annular taper surface is arranged in the connecting pipe fitting. The main body structure of the taper sealing ring is a sealing ring with a taper outer edge, and one end, with the small taper, of the taper sealing ring is inserted into the annular taper surface. Two ends of the taper elastic ring are communicated, and a plurality of notches are formed in each of two end faces of the taper elastic ring. The notches are evenly distributed on the two end faces of the taper elastic ring at intervals to form a cross-opening structure. The outer side face of the taper elastic ring has a taper, the big-head end face with large diameter fits the taper sealing ring, the thin head with small diameter penetrates a through hole of a fastening nut, and a to-be-connected pipe rod is inserted from the thin head. The pipe rod connecting device has the advantages that special processing of various pipe rods is not needed during connection, losses of the pipe rods are avoided, and the pipe rod connecting device is simple in method, low in mounting cost and good in locking, sealing and shock absorbing effects.

Description

technical field [0001] The invention relates to the field of pipe-rod quick connection, in particular to a pipe-rod connection device which can be repeatedly installed and disassembled without loss. Background technique [0002] With the development of industry and economy, the application of pipeline technology in civil and industry is becoming more and more extensive. There are various connection methods of pipeline engineering accessories such as various valves, faucets, sprinklers, water cocks, pressure gauges, etc. All of them are threaded connections. During the connection process, the pipes and rods to be connected need to be threaded accordingly. The process is complicated and requires a lot of manpower and material resources. The development of industry and society urgently needs a structure that can quickly connect various pipes and rods to meet the growing industrial needs. [0003] Refer to the Chinese patent "Connection method of wedge-conical tooth block combi...
