[0024] Schematic one-piece hexagonal crimp hose connector

[0025] refer to Figure 1 to Figure 2 According to a preferred embodiment of the utility model, the structure of the one-piece hexagonal crimping hose connector is as follows: Figure 1 As shown, it includes a core 20 and a sleeve 10, and the structure of the sleeve 10 is as follows Figure 1As shown, it has a first opening 101, a cavity 102 and a second opening 103, the first opening 101 and the second opening 103 are both connected to the cavity 102, and the first opening 101 and the second opening 103 are both connected to the outside. It should also be noted that one end of the core 20 is configured to pass through the second opening 103 and be placed in the cavity 102, and those skilled in the art should understand that the outer wall of the sleeve 10 is configured to be pressed by the outer wall pressing device, so that the inner wall of the sleeve 10 is deformed, and the core 20 placed in the cavity 102 is configured to match the external hose, that is, when the inner wall of the sleeve 10 is deformed, the inner wall of the sleeve 10 after deformation will be buckled on the external hose matched with the core 20, thereby limiting the position of the core 20.

[0026] Among them Figure 2 As shown, the wall surface forming the cavity 102 also has a plurality of first annular protrusions 1021, and the plurality of first annular protrusions 1021 are arranged at intervals, and the core 20 also has a plurality of evenly distributed second annular protrusions, wherein when the core 20 cooperates with the sleeve 10, the plurality of first annular protrusions 1021 respectively correspond to the plurality of second annular protrusions, and those skilled in the art should understand that the ends of the plurality of second annular protrusions provided on the core 20 are arranged to be sleeved with a rubber tube, and the end of the rubber tube is placed in the cavity 102, and the outside of the sleeve 10 can be pressed by a pressing device, so that the sleeve 10 is deformed, and then the plurality of first annular protrusions 1021 squeeze the rubber tube placed on the core 20, thereby fixing the position of the rubber tube by pressing.

[0027] It should also be noted that the end of the sleeve 10 away from the first opening 101 also has an extrusion portion 11, the extrusion portion 11 is integrally formed with the sleeve 10, and the second opening 103 is located at the end of the extrusion portion 11 away from the first opening 101. In addition, the cross-section of the extrusion portion 11 is hexagonal, and the external pressing device can also apply a force to the extrusion portion 11, so that the second opening 103 placed on the extrusion portion 11 is shrunk, so that the extrusion portion 11 is pressed on the core 20, thereby limiting the position of the core 20. In addition, the core 20 includes a first rod 21 and a second rod 22, and its local structure is as follows: Figure 2As shown, in addition, one end of the first rod body 21 facing away from the second rod body 22 is placed in the cavity 102, and a plurality of second annular protrusions are placed on the first rod body 21, and the other end of the first rod body 21 passes through the second opening 103 and is threadedly connected to the second rod body 22, wherein those skilled in the art should understand that the internal thread of the first rod body 21 and the external thread of the second rod body 22 are both spaced a predetermined distance from the second opening 103 to ensure that after the pressing of the extrusion portion 11 is completed, the thread of the first rod body 21 or the second rod body 22 will not be damaged by pressure, that is, the end of the second rod body 22 can be inserted into the first rod body 21 until the internal thread of the first rod body 21 contacts the external thread of the second rod body 22, and then the external pressing device presses the extrusion portion 11, and in order to improve the pressing effect, the extrusion portion 11 also has at least two first insertion holes 1101, and the two first insertion holes 1101 are both connected to the cavity 102 and close to the second opening 103. In addition, the outer wall of the first rod body 21 also has two oppositely arranged second insertion holes 2101, and the two first insertion holes 1101 correspond to the two second insertion holes 2101 one by one. It is worth mentioning that the above-mentioned second insertion holes 2101 can be replaced with arc grooves to reduce the difficulty of positioning.

[0028] The one-piece hexagonal crimping hose connector also includes two inserts 30, which are respectively placed in the first insertion hole 1101, and the ends of the two inserts 30 are also placed in the corresponding second insertion hole 2101. It is worth mentioning that when the extrusion part 11 is crimped by an external crimping device, the insert 30 is deformed due to the extrusion, so that the insert 30 can become an interference fit with the corresponding first insertion hole 1101 or second insertion hole 2101, thereby improving the connection strength between the extrusion part 11 and the first rod 21. The hexagonal structure of the extrusion part 11 can implement the user to set a wrench on the extrusion part 11, and then use the wrench to make the sleeve 10 and the first rod 21 rotate synchronously, thereby adjusting the overall length of the first rod 21 and the second rod 22, so that the one-piece hexagonal crimping hose connector can meet different installation sizes, thereby improving the connection convenience of the utility model. It should also be noted that our company's previous structural design in Figure A is a smooth surface, that is, the first insertion hole 1101, the second insertion hole 2101 and the insert 30 are not set, that is, the wall surface forming the cavity 102 and close to the second opening 103 is a smooth surface, and the surface of the first rod body 21 is also a smooth surface. Therefore, when the axial force applied to the above-mentioned sleeve 10 is too large, the sleeve 10 will detach from the core body 20.

[0029] In summary, the one-piece hexagonal crimping hose connector according to the embodiment of the present application is explained, which provides the one-piece hexagonal crimping hose connector with advantages such as adjustable core length, high practicality, and simple structure.

[0030] It is worth mentioning that in the embodiment of the present application, the one-piece hexagonal crimping hose connector has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the one-piece hexagonal crimping hose connector provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0031] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
