Abstract
The utility model discloses a double-end connector. The two ends of the connector are connecting sections (1) which are connected with clamping sleeves, the middle of the connector is a middle section (2), a through hole is formed inside the double-end connector, optical holes (4) are formed in the two ends of the through hole, and an inner hexagonal hole (5) is formed between the two optical holes (4). The outer surface of the middle section (2) is a circumferential surface. After the structure is adopted, due to the fact that the inner hexagonal hole is formed in the middle part of the through hole inside the double-end connector, an inner hexagonal spanner can be used for installing the double-end connector, assembling space is greatly reduced and the double-end connector is applicable to places with small space. In addition, due to the fact that the middle section is designed to be the outer circumferential surface, the size of raw materials is greatly reduced, and the materials are also saved.
Description
Technical field
The utility model relates to the auto parts machinery technical field, specifically is a kind of double end joint.
Background technique
At present, the double end joint is used in the various pipe-line systems.The double end joint of prior art forms by three sections, and two ends are respectively the linkage section that is connected with pipe, middle for profile be the intermediate section of outer-hexagonal.But there is following shortcoming in the double end joint of this structure:
1) since the double end joint in when assembling, the spanner that uses is to act on the outer-hexagonal of intermediate section, but in the very narrow and small situation of the Environmental Conditions of double end joint, obviously there is the problem of installing space deficiency in the matching used spanner of this outer-hexagonal, therefore, be not suitable for the position of narrow space;
2) simultaneously, the shape of outer-hexagonal is had edges and corners, and size is larger, therefore, relatively wastes material.
The model utility content
Technical problem to be solved in the utility model is that a kind of double end joint that is applicable to narrow space is provided.
For solving the problems of the technologies described above, the double end joint that the utility model provides, two ends are the linkage section that is connected with cutting ferrule, and the centre is intermediate section, and the inside of double end joint is through hole, and the two ends of described through hole are unthreaded hole, are inner hexagonal hole between two unthreaded holes.
The outer surface of described intermediate section is circumferential surface.
Described two linkage sections all are shaped with the outside thread that is threaded for cutting ferrule.
After adopting above structure, the utility model compared with prior art has the following advantages:
1) because the intermediate portion of double end joint interior bone is inner hexagonal hole, therefore, can utilize interior hand angle spanner that the double end joint is installed, greatly reduce assembly space, be applicable to the place of narrow space;
2) in addition, intermediate section is arranged to outer peripheral surface, greatly reduces raw-material size, therefore, has also saved material.
Description of drawings
Fig. 1 is the structural representation of the utility model double end joint.
Wherein: 1, linkage section; 2, intermediate section; 3, outside thread; 4, unthreaded hole; 5, inner hexagonal hole.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in more detail.
By the structural representation of the utility model double end joint shown in Figure 1 as can be known, its two ends are the linkage section 1 that is connected with cutting ferrule, and the centre is intermediate section 2, and the inside of double end joint is through hole, the two ends of described through hole are to be inner hexagonal hole 5 between 4, two unthreaded holes 4 of unthreaded hole.
The outer surface of described intermediate section 2 is circumferential surface.
Described two linkage sections 1 all are shaped with for the outside thread 3 that is threaded with cutting ferrule.
Claims (3)
1. double end joint, two ends are the linkage section (1) that is connected with cutting ferrule, and the centre is intermediate section (2), and the inside of double end joint is through hole, it is characterized in that: the two ends of described through hole are unthreaded hole (4), are inner hexagonal hole (5) between two unthreaded holes (4).
2. double end joint according to claim 1, it is characterized in that: the outer surface of described intermediate section (2) is circumferential surface.
3. double end joint according to claim 1, it is characterized in that: described two linkage sections (1) all are shaped with for the outside thread that is threaded with cutting ferrule (3).
