Abstract
The utility model relates to the technical field of pipe joints, particularly to a joint for connecting metal pipelines, especially automobile air conditioning connecting pipelines. A first ring-shaped groove (11) is formed on the outer ring at the initial end of a male joint, a guide ring (3) is embedded inside the first ring-shaped groove (11), a screwed segment is arranged at the end of a female joint, and a screw nut is arranged outside the female joint and is screwed up with screw threads on the male joint so as to achieve connection effect by screwing tightly the screw nut and the screw threads. An O-shaped sealing ring is arranged on the male joint and forms radial sealing with the female joint. The pipe joint has the advantages of easy manufacturing, convenient assembly and reliable sealing performance; and can prevent the sealing surface inside the female joint from being scratched when the male joint is inserted into the female joint during the application process, so as to avoid slow leakage.
Description
Technical field
The utility model relates to the pipe joint technical field, and the joint form that especially a kind of metal tubes connects is specially adapted to the connection of car air conditioner connecting pipeline.
Background technique
At present, the general male connector that connects between the pipeline of Shi Yonging, manufacture difficulty is bigger.Connect with the generation of tightening mutually of bolt by nut during connection.This connecting mode assembling is not too convenient, and in use when inserting negative joint, can cause male connector negative joint inner sealing face to abrade, thereby influence the sealing effect of seal ring, cause leakage, and be that later maintenance, replacing brought very big inconvenience.
Summary of the invention
The technical problems to be solved in the utility model is: in order to improve the rapidity that pipeline connects and to improve sealing reliability and durability after connecting, the utility model provides a kind of pipe joint, this kind pipe joint not only improves the speed and the convenience of loading and unloading, and has improved sealing effect and Security after connecting.
The technological scheme that its technical problem that solves the utility model adopts is: have the twice groove in male connector starting point outer ring, first groove is used for installing and the location plastic hoop, places O type packing ring in second groove.Male connector and negative joint have detachable connecting structure, and the negative joint end outer surface is provided with thread section, and there is a nut male connector end, and male connector is tightened mutually with thread section by nut with negative joint and connected.During assembling male connector is inserted negative joint, O type packing ring plays the radial seal effect between negative joint, male connector, and guide ring plays guiding and prevent to cause the abrasive effect of negative joint inner sealing face when male connector inserts negative joint.Whole assembly process is faster safer, adopts one O type packing ring and a guide ring, connects fast the reliable sealing purpose thereby reached.The male connector outer ring is provided with a projection near second groove surfaces, falls to prevent slide nut.
The beneficial effects of the utility model are: manufacture difficulty reduces, be convenient to assembling, sealing is reliable, can prevent in the using process that male connector from causing the scratch of negative joint inner sealing face when inserting negative joint, do not worry that male connector can cause the scratch of negative joint inner sealing face when inserting negative joint, thereby cause chronic leakage, simple in structure, cost reduces.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the male connector structural representation;
Fig. 2 is that male connector installs guide ring and seal ring schematic representation additional;
Fig. 3 is the negative joint structural representation;
Fig. 4 is a pipe joint assembling back schematic representation.
1. male connectors among the figure, 2. negative joint, 3. guide ring, 4.O type packing ring, 5. nut, 11. first grooves, 12. second grooves, 13. projections, 21. thread sections.
Embodiment
As shown in Figure 1, male connector is processed into Fig. 1 pattern, and guide ring 3 is installed in first groove 11 on the male connector 1, places O type packing rings 4 in male connector 1 front end reprocessing one sealing second groove 12, the second grooves 12; Negative joint 2 is processed into Fig. 3 pattern, and front end is provided with a thread section 21, and caliber can make the effective sealing of O type packing ring generation be as the criterion with male connector insertion post gap in the thread section; During assembling, as shown in Figure 4, male connector 1 inserts in the negative joint 2, during projection 13 parts of negative joint end to male connector outer ring, nut 5 is connected mutually with thread section 21 and tightens, and negative joint can't be skidded off from male connector, thereby produce the effect of connection.
Claims (5)
1. a pipe joint has a male connector (1), and a negative joint (2) and a guide ring (3) is characterized in that: the starting point outer ring of male connector is provided with first annular groove (11), and guide ring (3) cover is embedded in first annular groove (11).
2. pipe joint according to claim 1, it is characterized in that: said male connector and negative joint have detachable connecting structure and are, the negative joint end outer surface is provided with thread section (21), there is a nut (5) the male connector end, and male connector is tightened mutually with thread section (21) by nut (5) with negative joint and connected.
3. pipe joint according to claim 2 is characterized in that: said male connector and negative joint have detachable connecting structure and are, surface, male connector (1) outer ring, end is provided with a projection (13) that prevents nut (5) landing.
4. pipe joint according to claim 1, it is characterized in that: the inner side of first annular groove (11) of male connector (1) starting point is provided with second annular groove (12) again, produces the O-ring gasket (4) of radial seal when installation one makes male connector connect with negative joint in second annular groove (12).
5. pipe joint according to claim 1 is characterized in that: described guide ring (3) is a plastic material.
