Abstract
Description
Technical Field
[0001] This utility model relates to the field of hose connector technology, and in particular to a crimp-type hose connector. Background Technology
[0002] Hose fittings are components used to connect hoses and metal pipes. In hydraulic systems, hydraulic oil is delivered via hoses, utilizing the flexibility of rubber hoses to adapt to the positional relationships between hydraulic components. The rubber hoses are then connected to the hydraulic components via metal pipes. Hydraulic fittings play a crucial role in connecting rubber hoses and metal pipes.
[0003] However, existing hose fittings have certain shortcomings:
[0004] Existing hose fittings with threaded connections provide a tight and secure connection when connecting metal pipes. However, when connecting hoses, the hoses are elastic and lack a matching thread groove on their outer wall. Furthermore, the internal threads of the fittings are shallow. When the hose is conveying hydraulic media, the high pressure of the medium can cause the connection to the hose to detach under pressure. Alternatively, after prolonged use, the internal threads of the fitting may wear down significantly, making it unable to secure the hose.
[0005] Therefore, a crimp-type hose connector is proposed to solve the above problems. Utility Model Content

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0024] Embodiment: refer to Figures 1-6 The utility model discloses a buckle pressing type hose joint, including pipe body 1, the inside of pipe body 1 is provided with connecting pipe 2, connecting pipe 2 is adapted with pipe body 1, and the diameter of connecting pipe 2 is less than the diameter of pipe body 1, and the both sides of the outer wall of pipe body 1 are provided with buckle pressing assembly, and the buckle pressing assembly is adapted with pipe body 1 and connecting pipe 2 respectively, and the buckle pressing assembly includes the metal elastic key 3 of setting up on the outer wall of pipe body 1, and the end of metal elastic key 3 is provided with fixed sheet 4, and fixed sheet 4 is arc, and fixed sheet 4 is adapted with pipe body 1 and connecting pipe 2 respectively, and the bottom outer wall of fixed sheet 4 is provided with the fixed tooth 5 of equidistance distribution, and fixed tooth 5 is trapezoidal, and fixed tooth 5 is adapted with connecting pipe 2, and the both sides of the outer wall of pipe body 1 are provided with elastic groove 6, and elastic groove 6 is adapted with metal elastic key 3, and the outer wall of pipe body 1 is provided with the equidistance distribution of inner thread with the outer thread of adapting with the inner thread through the screw thread rotation installation locking ring 7 and connecting ring 10, and the inner wall of locking ring 7 and connecting ring 10 is provided with the equidistance distribution of inner thread.
[0025] With the above structure: During operation, the hose to be connected is inserted into the tube body 1, the outer wall of the hose contacts the inner wall of the tube body 1, and the inner wall of the hose contacts the outer wall of the connecting tube 2. Then, the locking ring 7 is rotated. As the locking ring 7 rotates, it gradually squeezes the metal spring key 3. The inner wall of the locking ring 7 presses the metal spring key 3 into the tube body 1. Under the pressure, the fixing plate 4 squeezes and fixes the hose. The fixing teeth 5 at the bottom of the fixing plate 4 contact the hose and firmly lock the hose in place, thereby achieving a fixed connection of the hose. Compared with traditional threaded hose connections, the fixing teeth 5 fix the hose more deeply, and the hose is less likely to fall off due to the threads inside the connector being worn down, which facilitates the long-term fixation of the hose.
[0026] like Figure 4 As shown, the locking ring 7 is located between the connecting ring 10 and the clamping assembly. The locking ring 7 is compatible with the metal spring key 3. A sealing sleeve 11 is provided on the inner wall of the connecting ring 10. The sealing sleeve 11 is compatible with the connecting ring 10. The inner wall of the connecting ring 10 is provided with equally spaced threaded grooves. The threaded grooves are compatible with the sealing sleeve 11. When the hose is connected, the locking ring 7 fixes the hose connection end. Then, the connecting ring 10 is rotated, and the threaded grooves inside it can connect the connecting ring 10 to the faucet. The sealing sleeve 11 seals the connection to prevent water leakage.
[0027] like Figure 6 As shown, anti-slip pads 8 are provided on the outer wall of the connecting pipe 2 and the inner wall of the pipe body 1. The anti-slip pads 8 are adapted to the pipe body 1 and the connecting pipe 2 respectively. The outer wall of the connecting pipe 2 is provided with a groove 9, which is adapted to the fixing tooth 5 and the connecting pipe 2 respectively. When the hose is connected, the anti-slip pads 8 increase the friction between the connecting pipe 2, the pipe body 1 and the hose, making the hose less likely to loosen and fall off.
[0028] The working principle of this practical application is as follows:
[0029] During operation, the hose to be connected is inserted into the tube body 1, with the outer wall of the hose contacting the inner wall of the tube body 1 and the inner wall of the hose contacting the outer wall of the connecting tube 2. Then, the locking ring 7 is rotated. As the locking ring 7 rotates, it gradually squeezes the metal spring key 3. The inner wall of the locking ring 7 presses the metal spring key 3 into the tube body 1. Under pressure, the fixing plate 4 squeezes and fixes the hose. The fixing teeth 5 at the bottom of the fixing plate 4 contact the hose and firmly lock the hose in place, thus achieving a fixed connection of the hose. Compared with traditional threaded hose connections, the fixing teeth 5 fix the hose more deeply, making it less likely for the hose to fall off due to the threads inside the connector being worn down, thus facilitating long-term fixation of the hose.
[0030] When the hose is connected, the locking ring 7 fixes the hose connecting end, then the connecting ring 10 is rotated, the thread groove arranged in the connecting ring 10 can connect the connecting ring 10 with the faucet, the sealing sleeve 11 seals the connecting part to prevent water leakage, when the hose is connected, the non-slip mat 8 increases the friction between the connecting pipe 2, the pipe body 1 and the hose, so that the hose is not easy to loosen and fall off.
[0031] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
