The outer diameter of the triangular protrusion is slightly larger than the inner diameter of the hose 1 〇 1. Therefore, as shown in Fig. 3B, when the soft 瞢1ηι你$田秋官101 is inserted into the hose insertion portion lc, the annular elastic body pushes between the hose autumn T 1U1 and the hexagonal projection Id. The top and the deformation, therefore, the elastic body effectively avoids the detachment of the hose 1〇1 and the liquid leakage. The method of processing this connector is as described in the first and second embodiments, and the description will be omitted here. (Fourth Embodiment) Next, a fourth embodiment of the present invention will be described with reference to Figs. 4A to 4C. Fig. 4A is a side elevational view and a partial cross-sectional view showing the hose connector in accordance with the fourth embodiment. Fig. 4B is a front, side and partial cross-sectional view showing the hose connector showing the case where the hose connector according to the fourth embodiment is inserted into the hose. The f 4C ffi is a side view and a partial cross-sectional view of the 'display & pipe connector' showing the case where the hose is connected to the hose 16 201139912 by locking the nut in the fourth practical example. The fourth embodiment differs from the third embodiment only in that a ring-shaped ring made of an elastic material is fitted in the four grooves of the rectangular dentate projection and the groove le, which are formed in the hose of the joint 1 Enter the end of the lc. Except for this difference, the structure in the fourth embodiment is the same as in the third embodiment. Fig. 10A is an enlarged view showing that the hose 101 is snapped into both the projection and the groove. Further, the plan view shows an enlarged view of the triangular projection and the groove 25b formed in the inner edge of the claw body in the fourth embodiment and the hose 1〇1 being engaged into the projection and the groove. The hose 101 is deformed according to the shape of both the projection and the groove and the hose 101 is slid into and gripped by the grooves of the two projections and grooves, thus the hose and the hose connector The system is firmly connected. The other structure is the same as that in the third embodiment, and the description will be omitted here. Further, the method of processing this connector is as described in the first embodiment, and thus the description will be omitted. By fitting a 〇-shaped ring (7)_ring lf made of an elastic material, the inner edge of the hose and the 0-ring ring that are engaged into the rectangular dentate projection of the hose insertion portion 1C and the groove of the groove 16 The connection is firmly connected, so that the liquid can be prevented from leaking. Further, the rectangular dentate hose that is snapped into the joint i can be protected. The groove 16 is the structure of the third embodiment. The 0-shaped 裱 If is assembled in a groove formed in the rectangular dentate protrusion and the groove of the joint, however, it may also be a 0-shaped ring 丨f-equipped in the first or second embodiment. In the groove of the joint i described therein, the annular elastic body having the angular projection id of = 17 201139912 is not assembled to the joint 丄. Further, the above embodiment is characterized by the joint i and the sleeve 2 〇 The components are described as follows, but the two components may be integrally formed. Further, the above-mentioned protrusions and grooves le formed in the hose insertion portion lc of the joint 主要 are mainly formed in a rectangular tooth shape. However, it may also be different from the rectangle described in the first embodiment. Further, the above-mentioned shape is described by the triangular protruding portion ld of the joint 1 being an annular elastic body, and other non-elastic materials such as metal may be used. Further, the protruding portion Id may be used. More preferably, the width of the protrusion and the width of the protrusion of the joint and the groove of the groove k are h 5 mm or more than 丨5 mm, respectively, and further, the depth of the groove is better. 8mm or more than 〇. 8mm. Further, in the first to fourth embodiments, the sealing structures of the hose joints may be configured according to the purpose. In detail, they are formed on the claws, the body The shape of the protrusion and the groove and the hose formed in the joint i are placed 4 times. The shape of the P and the groove may be a triangular tooth shape or a rectangular read shape. Further, the groove is outside The type may be a slightly elliptical outer blue or a 2 trapezoidal outer shape. Further, the protruding portion of the claw-shaped body 25 and the projection and the groove of the groove and the soft-input portion 1C are disposed in a staggered manner with each other. In the way, the protrusions and grooves can be of various shapes. The hose is firmly connected to the protrusion and the groove of the joint to become larger, so that the hose can be effectively sealed and the hose can be prevented from coming off and the liquid leaks. Steps on the hose connector described above, then The structure can be more conducive to the joint strength of the joint! and the sleeve 2. The above sleeve is made of polyamine resin (p66lyamide such as PA66 (Nyl〇n 66) from the viewpoint of manufacturing and assembly of 18 201139912. The above-mentioned joints are made of a metal such as brass or the like from the viewpoint of screwing, and therefore, the sleeve 20 made of polyamide resin is swelled by the sweiUng effect. Changing the size 'is caused by moisture (m〇isture). In this case, the sleeve 20 corresponding to the joint 1 is resized so that there is a slight slip between the two, resulting in assembly instability. As shown in Fig. 11A, an annular v-shaped groove (j) formed in the axial direction of the main head u on the fitting area corresponds to the sleeve 20. Corresponding to this structure, such as the first! As shown in Fig. 1B, a ring-shaped large portion (annular pr〇jecti〇n) 26 is formed on the assembly head in the axial direction of the head of the sleeve, corresponding to the joint 丨. In this manner, the annular V-shaped groove ij on the joint 1 and the annular projection 26 on the sleeve 2 can secure the joint between the joint 1 and the sleeve 2, and prevent the hose from coming loose. . More specifically, even if the joint i and the sleeve 2 are changed in size due to changes in the external environment, the difference in the dimensional change will be at least large. The sealing of p 26 and the braided v-shaped groove ij makes the fixing of the eight s more stable to prevent the hose from coming loose. 1) Γ-step As shown in Fig. 12A, the joint 20 having the v-shaped groove lj is not in the form of a 0-ring (〇_ring) lk. And, as shown in Fig. 12B, the sleeve does not have an annular projection 26 as in the first embodiment. When the ring U is fixed between the joint 丨 and the sleeve 2 = = the formula: the seal for the joint 1 can be used. The ring of the ring lk: deformation = 2. The difference in size change caused by the change in the shape of the double-shaped and broken dimension will be small. 19 201139912 The sealing state of the seal "in this way" between the joint 1 and the sleeve 20 can be improved, and The hose can be prevented from coming loose.
