[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0024] like Figure 1 and Figure 2 As shown, the self-locking hose assembly of this utility model includes:
[0025] Hose body 1;
[0026] The first connecting component 2 and the second connecting component 3 are respectively connected to both ends of the hose body 1. The structure of the first connecting component 2 and the second connecting component 3 are the same. Both the first connecting component 2 and the second connecting component 3 include a sleeve 4 and a pagoda head 5. The sleeve 4 is fitted onto a part of the pagoda head 5. The pagoda head 5 is used to connect the hose body 1. The sleeve 4 is used to lock the pagoda head 5 and the hose body 1. The sleeve 4 serves to seal and clamp.
[0027] like Figures 2 to 4 As shown, the pagoda head 5 includes a clamp head 51, a rod body 52, a first clamping ring 53, and a second clamping ring 54. The clamp head 51 is fixed to one end of the rod body 52. The first clamping ring 53 and the second clamping ring 54 are both located on the rod body 52. One side of the first clamping ring 53 is attached to the clamp head 51, and the clamp head 51 is engaged with the hose body 1.
[0028] In this embodiment, the sleeve 4 includes a cylinder 41, a first groove 42, and a second groove 43. The first groove 42 and the second groove 43 are both located on the inner wall of the cylinder 41. The first retaining ring 53 engages with the first groove 42, and the second retaining ring 54 engages with the second groove 43, so that the pagoda head 5 and the sleeve 4 are tightly connected to prevent separation.
[0029] Specifically, the diameter of the end of the clamp 51 near the first retaining ring 53 is larger than the diameter of the end of the clamp 51 away from the first retaining ring 53. This facilitates a tighter engagement between the clamp 51 and the hose body 1, preventing the clamp 51 from detaching from the hose body 1. The sleeve 4 has a first through hole 44. The pagoda head 5 includes a sealing cap 55 and a second through hole 57. The rod 52 passes through the first through hole 44. The sealing cap 55 is attached to one end of the cylinder 41. A protrusion 56 is provided in the middle of the sealing cap 55. The second through hole 57 extends from the clamp 51 to the protrusion 56. The protrusion 56 is used for welding with other components. In addition, the cylinder 41 has a groove 45, which is used to indicate the assembly direction and facilitate engagement with other components.
[0030] like Figure 5 As shown, the hose body 1 includes a wear-resistant layer 11, a corrosion-resistant layer 12, and a fiber layer 13. The wear-resistant layer 11 is located outside the corrosion-resistant layer 12, and the corrosion-resistant layer 12 is located outside the fiber layer 13. The wear-resistant layer 11 can be made of polycaprolactone and has wear resistance. The corrosion-resistant layer 12 can be made of polytetrafluoroethylene and has acid and alkali corrosion resistance. The fiber layer 13 can be made of glass fiber and has leak-proof capability.
[0031] All components of this utility model are general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In use, first, the two sleeves 4 are respectively fitted onto both ends of the hose body 1, and then the two pagoda heads 5 are inserted respectively. The clamps 51 of the pagoda heads 5 engage with the hose body 1, the first clamping ring 53 engages with the first clamping groove 42, and the second clamping ring 54 engages with the second clamping groove 43, thus achieving a self-locking installation that will not fall off. This utility model can complete assembly without crimping and without leakage, realizing pipeline connection in confined spaces and facilitating installation. After assembling the hose body 1, the first connecting component 2, and the second connecting component 3, the self-locking hose assembly of this utility model can achieve a pull-out force of over 100N and a pipeline pressure of 3.0MPa, without the hose joint falling off.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
