Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail the utility model.
Referring to Fig. 1, a kind of hydralic hose attachment means, including the first joint 1(Shown in Fig. 5, Fig. 6)With the second joint 2(Figure 7th, shown in Fig. 8), the first joint 1 and the second joint 2 be hollow structure, and the interior connection end of the first joint 1 is provided with female thread structure 1-1, the interior connection end of the second joint 2 is provided with the external thread structure 2-1 matched with the internal thread of the first joint 2, the first joint 1 and Two joints 2 are threaded connection.It is 60 degree that the external screw thread 2-1 of the internal thread 1-1 of the first joint 1 and the second joint 2 is angle of thread Tapered tread or common fine thread, tapered tread or common fine thread have preferable sealing effectiveness.First joint 1 and Hollow sealed valve core is provided between two joints 2, hollow sealed valve core is circular cone center valve element 3(Shown in Fig. 2), sealed valve core Material be No. 45 steel.The outer connection end of the first joint 1 and the second joint 2 is bolt-type center tip structure 1-2, using moral mark Or GB, using U-shaped card fixing tube, U-shaped card plays connection function, and jam-packed sealing function is played in sealing.
Referring to Fig. 2, the one end of circular cone center valve element 3 is conical structure 3-3, and the other end is column structure 3-4, column structure 3- 4 are placed in the endoporus 1-3 of the first joint 1, and the inner conical surface 2-2 of the taper seat of conical structure 3-3 and the second joint 2 is in the first joint 1 and second joint 2 screw rear fitted seal, the excircle at two ends is respectively equipped with first annular groove 3-1 and the second annular groove 3-2。
Referring to Fig. 3, sealed valve core can be two-way center valve element 4, and two-way center valve element 4 is provided with annular boss 4- for middle part 1 column structure, the excircle at two ends is respectively equipped with first annular groove 3-1.Female adapter sebific duct need extend when in case of Non- bolt-type hydralic hose, then need to be attached with male connection using two-way center valve element 4, reuses and matches with it Hydralic hose be attached, realize extension function, need to such as connect other model hydralic hoses can also apply mechanically the method.
