Abstract
The utility model discloses a joint component of a hose. The joint component comprises a joint core and a joint nut. The joint nut is clamped at one end of the joint core. The joint nut and the joint core are jointly clamped with a plug connector. The other end of the joint core is a plug portion plugging into the hose. The outer surface, close to an end, of the plug portion is provided with a coarse-pitch thread, and a fine thread is arranged at the rear end of the coarse-pitch thread. Since the outer surface, close to an end, of the plug portion is provided with the coarse-pitch thread, and the fine thread is arranged at the rear end of the coarse-pitch thread, the hose and the joint component are primarily sealed by the aid of the coarse-pitch thread outside the plug portion and are sealed secondarily by the fine thread at the rear end of the coarse-pitch thread, and accordingly, sealing effect of the joint component and the hose is guaranteed, the joint component for the hose and the hose can be firmly connected, and the joint component is not easy to burst out by the pressure in the hose.
Description
Technical field
The utility model relates to a kind of hose joint assembly.
Background technique
At present, in the oil circuit delivery line of engineering mechanical device (for example digging machine, road roller, loader or fork truck etc.) or oil pump etc., generally adopt hose joint assembly extra-lnigh tension hose joint assembly to connect flexible pipe and engineering mechanical device or oil pump.Hose joint assembly one end is connected with flexible pipe, and the other end is connected with the plug connector of the oil delivery hose of engineering mechanical device or oil pump.Existing hose joint assembly structure generally comprises joint fuse and collar nut, and collar nut is fastened in joint fuse one end, and the joint fuse the other end is for inserting the cutting graftage part of flexible pipe, and the cutting graftage part outer surface is provided with coarse-pitch thread.The coarse-pitch thread that utilizes the cutting graftage part outer surface to be provided with is connected with flexible pipe, but that such Placement makes the cutting graftage part be connected with flexible pipe is insecure, all difficult assurance of its join strength, sealing, and easy leakage, even come off.
Summary of the invention
In order to overcome the deficiency of existing technology, the purpose of the utility model provides a kind of being connected firmly and the hose joint assembly of good airproof performance.
A kind of hose joint assembly of the utility model; Comprise joint fuse and collar nut; Collar nut is fastened in joint fuse one end, and collar nut and joint fuse be the clamping plug connector together, and the joint fuse the other end is for inserting the cutting graftage part of flexible pipe; Said cutting graftage part outer surface is provided with coarse-pitch thread near the port, and the coarse-pitch thread rear end is provided with fine thread.
The ratio of said coarse-pitch thread length and fine thread length is 1.5-2:1.
One end of said joint fuse and collar nut cutting ferrule is provided with a circle annular protrusion, and the corresponding end of said collar nut and annular protrusion is provided with the snap collar that bends inwards, and said collar nut is fastened in outside the annular protrusion of said joint fuse by its snap collar.
Adopt the structure of the utility model; Outer surface is provided with coarse-pitch thread near the port in the cutting graftage part of hose joint assembly, and the coarse-pitch thread rear end is provided with fine thread again, so earlier behind the coarse-pitch thread and flexible pipe primary seal outside the cutting graftage part; Fine thread with the coarse-pitch thread rear end seals flexible pipe once more again; Thereby guarantee the sealing effect of hose joint assembly and flexible pipe, and hose joint assembly and flexible pipe be connected firmly, difficultly washed open by the pressure in the flexible pipe.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model hose joint assembly.
Embodiment
As shown in Figure 1; The utility model hose joint assembly comprises joint fuse 1 and collar nut 2, and collar nut 2 is fastened in joint fuse 1 one ends; Collar nut 2 and joint fuse 1 be the clamping plug connector together; Joint fuse 1 the other end is for inserting the cutting graftage part 4 of flexible pipe, and said cutting graftage part 4 outer surfaces are provided with coarse-pitch thread 41 near the port, and coarse-pitch thread 41 rear ends are provided with fine thread 42.
The ratio of said coarse-pitch thread 41 length and fine thread 42 length is 1.5-2:1.When hose joint assembly uses; Flexible pipe inserts its cutting graftage part 4; Coarse-pitch thread outside the cutting graftage part 4 41 earlier and behind the flexible pipe primary seal, 42 pairs of flexible pipes of the fine thread of coarse-pitch thread 41 rear ends seal once more like this, thereby guarantee the sealing effect of hose joint assembly and flexible pipe; And hose joint assembly and flexible pipe are connected firmly, and are difficult for being washed open by the pressure in the pipe.
The other end of hose joint assembly is connected with the engineering mechanical device (for example digging machine, road roller, loader or fork truck etc.) or the oil delivery hose of oil pump by plug connector by joint fuse 1 and collar nut 2 clamping plug connector together.
Said joint fuse 1 is provided with a circle annular protrusion 3 with an end of collar nut 2 cutting ferrules; Said collar nut 2 is provided with the snap collar 5 that bends inwards with annular protrusion 3 corresponding ends, and said collar nut 2 is fastened in outside the annular protrusion 3 of said joint fuse 1 by its snap collar 5.
Claims (3)
