DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 7As shown, the utility model provides a high-pressure hose connector, including a first connector 1 and a second connector 2, and both ends of the first connector 1 and the second connector 2 are connected with a connecting pipe 8, and a cassette groove is provided on the connecting pipe 8, and the cassette groove is used to put one end of the hose on the connecting pipe 8, and then use a steel wire or other binding parts to wrap the hose around and bind it in the cassette groove to fix the connection of the hose, the surface of the first connector 1 is hinged with a positioning plate 3, the bottom end of the positioning plate 3 is fixedly connected to a limiting plate 6, the other end of the positioning plate 3 is fixedly connected to a first compression spring 22, and the bottom end of the first compression spring 22 is fixedly connected to the surface of the first connector 1, through the design of the first compression spring 22 When the first and second couplings 2 are in the same position, the first and second couplings 2 are in the same position, and the first and second couplings 2 are in the same position. When the first buckle 1 and the second buckle 2 are buckled and connected, one end of the push plate 4 will extend under the positioning plate 3, and the limiting plate 6 will be moved to lift the positioning plate 3 upward, so that the push plate 4 can continue to push and move on the bottom surface of the positioning plate 3. When the first buckle 1 and the second buckle 2 are buckled and connected, the push plate 4 will position the limiting groove 15 through the limiting plate 6, and the card block on the limiting plate 6 will also be inserted into the card slot in the limiting groove 15 to prevent the first buckle 1 and the second buckle 2 from rotating at will. When the first buckle 1 and the second buckle 2 are normally rotated and buckled, the card block can be inserted into the card slot in turn. When the second buckle 2 rotates in the opposite direction, the card block will be limited in the card slot, so that the first buckle 1 and the second buckle 2 cannot rotate in the opposite direction. In addition, under the setting of the above structure, the high-pressure resistance effect of the connection between the first buckle 1 and the second buckle 2 can be further improved, and the operation is also more convenient, without the need for unnecessary operations by personnel, and when the first buckle 1 and the second buckle 2 are separated, it is only necessary to press the end of the positioning plate 3 away from the pushing plate 4 to separate the limiting plate 6 from the limiting slot 15, so that the first buckle 1 and the second buckle 2 can rotate and separate normally, thereby improving the locking convenience between the first buckle 1 and the second buckle 2.

[0026] like Figure 1 , Figure 2 and Figure 7As shown, the end of the pushing plate 4 away from the positioning plate 3 is fixedly connected to the moving plate 5, the first buckle 1 is provided with a mounting groove 16, the inner wall of the mounting groove 16 is fixedly connected to the guide rod 14, the moving plate 5 slides in the mounting groove 16 and is sleeved on the surface of the guide rod 14, the surface of the guide rod 14 is sleeved with a spring 21, and the two ends of the spring 21 are respectively fixedly connected to the inner wall of the mounting groove 16 and the surface of the moving plate 5. Through the setting of the above structure, when the first buckle 1 and the second buckle 2 are completed, the moving plate 5 can continue to be pushed to move, thereby driving the pushing plate 4 to continue to extend into one side of the positioning plate 3 until the moving plate 5 can no longer be pushed, thereby utilizing the elastic force of the spring 21 to improve the clamping stability between the limiting plate 6 and the limiting groove 15, and further improve the connection effect of the first buckle 1 and the second buckle 2.

[0027] like Figure 2 and Figure 4 As shown, the bottom surface of the positioning plate 3 is fixedly connected with a support plate 7, and the bottom end of the support plate 7 is supported on the surface of the first buckle 1. Through the setting of the support plate 7, when the first buckle 1 and the second buckle 2 are separated, the surface of the first buckle 1 at the bottom of the support plate 7 can be supported, thereby facilitating the subsequent pushing plate 4 to extend under the positioning plate 3.

[0028] like Figure 2 As shown, the positioning plates 3 and the pushing plates 4 are both arranged in two groups, and the two groups of positioning plates 3 and the two groups of pushing plates 4 are arranged symmetrically. By setting the two groups of positioning plates 3 and the two groups of pushing plates 4, the connection stability of the first buckle 1 and the second buckle 2 after being engaged can be improved.

[0029] like Figure 1 and Figure 5 As shown, the surface of the connecting pipe 8 is fixedly connected to two opposite sleeve rods 13, and the surface of each sleeve rod 13 is sleeved with a sleeve plate 10, and each sleeve plate 10 is elastically provided with a ring 9, and the ring 9 is adapted to the tape groove on the connecting pipe 8, and the two rings 9 can be detachably connected. Through the setting of the above structure, when the water hose is fixed in the tape groove on the connecting pipe 8 by steel wire or other binding parts, the two sleeve plates 10 can be pushed to move and drive the two rings 9 to move together until the two rings 9 are moved to the tape groove, and the two rings 9 are connected and fixed to each other, which can improve the firmness of the connection between the water hose and the connecting pipe 8, thereby ensuring the high pressure resistance effect between the water hose and the connecting pipe 8.

[0030] like Figure 1 and Figure 5As shown, each holding ring 9 is fixedly connected with a plurality of positioning rods 11, and the positioning rods 11 penetrate into the sleeve plate 10, and the surface of each positioning rod 11 is sleeved with a second compression spring 12, and the second compression spring 12 is fixedly connected between the sleeve plate 10 and the holding ring 9, and the inner wall of each holding ring 9 is provided with a groove, and the groove is set to avoid the steel wire or the clamp. Through the setting of the positioning rod 11 and the second compression spring 12, when the water hose is not connected to the connecting pipe 8, the holding ring 9 will slide to the surface of the connecting pipe 8 and stay away from the cassette groove to prevent the holding ring 9 from sliding at will, which is conducive to the subsequent connection of the water hose. When the water hose is connected, the holding ring 9 can be slid to the cassette groove and automatically sleeved on the joint of the connecting pipe 8.

[0031] like Figure 1 , Figure 5 and Figure 6 As shown, the two ends of the two holding rings 9 are respectively fixed with a first fixing block 18 and a second fixing block 19, and the inner walls of the two second fixing blocks 19 are hinged with screws 20, and the surface of each screw 20 is threadedly connected with a positioning tube 17, and the surface of the positioning tube 17 is in contact with the surface of the first fixing block 18, and the first fixing block 18 is provided with a groove adapted to the positioning tube 17. When the positioning tube 17 contacts the first fixing block 18 by rotating on the screw 20, it can be inserted into the groove, thereby avoiding the arbitrary swing of the screw 20, further improving the connection stability between the two holding rings 9. Through the setting of the above structure, in order to facilitate the connection of the two holding rings 9, during the specific operation, it is only necessary to flip the screw 20 into the first fixing block 18, and then rotate the positioning tube 17 to move on the screw 20, so that the positioning tube 17 contacts the first fixing block 18 and the second fixing block 19, further ensuring the stability of the connection between the two holding rings 9, making the operation more convenient, and improving the high pressure resistance effect after the water hose is connected.

[0032] When the first and second latches 1 and 2 are connected, it is only necessary to fasten the first and second latches 1 and 2 together, and at this time, one end of the pushing plate 4 will extend into the lower part of the positioning plate 3, and the limiting plate 6 will be pushed upward to enable the pushing plate 4 to be continuously pushed and moved on the bottom surface of the positioning plate 3, and then the first and second latches 1 and 2 are rotated to make the clamping parts therein rotate and fasten, at this time, the clamping block on the limiting plate 6 will also be inserted into the clamping slot in the limiting groove 15, and then the moving plate 5 is continuously pushed to move, thereby driving the pushing plate 4 to continuously extend into one side of the positioning plate 3 until the moving plate 5 can no longer be pushed, thereby utilizing the elastic force of the spring 21 to improve the clamping stability between the limiting plate 6 and the limiting groove 15, effectively preventing the first and second latches 1 and 2 from rotating at will, and also improving the high pressure resistance effect of the connection between the first and second latches 1 and 2, and making the operation more convenient, and can be completed without unnecessary operation by personnel. The connection between the first buckle 1 and the second buckle 2 is formed, which effectively prevents the first buckle 1 and the second buckle 2 from rotating at will, and also improves the high-pressure resistance effect of the connection between the first buckle 1 and the second buckle 2. The operation is also more convenient, and no unnecessary operation is required. When the first buckle 1 and the second buckle 2 need to be separated, it is only necessary to press the end of the positioning plate 3 away from the pushing plate 4 to separate the limiting plate 6 from the limiting groove 15, so that the first buckle 1 and the second buckle 2 can rotate and separate normally, thereby improving the locking convenience between the first buckle 1 and the second buckle 2. When the water hose is fixed in the tape groove on the connecting pipe 8 by steel wire or other binding parts, the two sleeve plates 10 can be pushed to move and drive the two holding rings 9 to move together until the two holding rings 9 are moved to the tape groove, and the two holding rings 9 are connected and fixed to each other, thereby improving the firmness of the connection between the water hose and the connecting pipe 8, thereby ensuring the high-pressure resistance effect between the water hose and the connecting pipe 8.
