[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figures 1 to 4 As shown, an anti-loosening connection valve of an embodiment of the present invention includes a valve body 1; a connecting pipe 12 is installed at the port of the valve body 1; a nut 13 is rotatably connected to the middle part of the connecting pipe 12; the nut 13 is threadedly matched with the port of the valve body 1; a mounting ring 14 is rotatably connected to the middle part of the valve body 1; a limiting plate 15 is symmetrically provided in the middle part of the mounting ring 14 for sliding connection; a latch 16 is detachably installed in the middle part of the mounting ring 14 and the limiting plate 15; a rotation limiting component is installed in the middle part of the valve body 1; when working, the connecting pipe 12 is inserted into the port of the valve body 1, and then the nut 13 is rotated to the middle part of the port of the valve body 1 to complete the connection. The tube 12 and the valve body 1 are connected, and then the mounting ring 14 is rotated so that a pair of limit plates 15 are respectively located at two planes in the middle of the nut 13, and then the limit plates 15 are slid to the plane of the nut 13, and then the pin 16 is inserted into the holes in the middle of the mounting ring 14 and the limit plates 15 so that the limit plates 15 will no longer slide easily, thereby maintaining a pair of limit plates 15 at the two planes of the nut 13, so that the nut 13 will not rotate easily. Through the above structure, the rotation of the nut 13 can be restricted after the valve body 1 is connected to the connecting tube 12, thereby reducing the occurrence of loosening of the connecting tube 12 caused by the rotation of the nut 13.
[0024] like Figures 1 to 3 As shown, the rotation limiting assembly includes a gear ring 2; the gear ring 2 is fixedly connected to the middle part of the valve body 1; the middle part of the mounting ring 14 is slidably connected with a tooth block 21; the tooth block 21 is meshed with the gear ring 2; the outer wall of the mounting ring 14 is fixedly connected with an elastic band 22; the middle part of the elastic band 22 is fixedly connected to the middle part of the tooth block 21; during operation, when it is necessary to rotate the mounting ring 14 to adjust the position of the limit plate 15, the tooth block 21 is pulled so that the tooth block 21 is no longer meshed with the gear ring 2, and then the mounting ring 14 is rotated and adjusted. After the adjustment is completed, the tooth block 21 is released, and the tooth block 21 will move toward the direction of the gear ring 2 under the elastic force of the elastic band 22 and mesh with the gear ring 2, so that the limit plate 15 will no longer rotate easily. Through the above structure, the rotation of the mounting ring 14 can be conveniently restricted and released, the operation is convenient, and the convenience of use of the device is improved.
[0025] As shown in Figures 1 to 4 The end of the valve body 1 is fixedly connected with a fixed ring 3; the side of the fixed ring 3 facing the mounting ring 14 is provided with a sliding groove 31; the bottom of the limiting plate 15 is fixedly connected with an insertion plate 32; during operation, when the sliding limiting plate 15 is moved, the insertion plate 32 is inserted into the sliding groove 31, and when the nut 13 is about to rotate and the ends of the pair of limiting plates 15 are pushed outward, the limiting plate 15 may be bent at the connection with the mounting ring 14, thereby allowing the nut 13 to escape from the limitation. By inserting the insertion plate 32 into the sliding groove 31, even if the limiting plate 15 is bent under stress, the bending point will be near the insertion plate 32, so that the limiting plate 15 must be bent at a larger angle before the nut 13 can escape from the limitation. Through the above structure, the rotation limiting effect of the nut 13 can be further improved, and the loosening of the connecting pipe 12 caused by the rotation of the nut 13 can be further reduced.
[0026] As shown in Figures 1 to 4 The middle part of the pair of mounting rings 14 is rotatably and slidably connected with a sleeve ring 4; the end of the mounting ring 14 is fixedly connected with a limiting block 41; during operation, the sleeve ring 4 is slid along the limiting plate 15 to the nut 13, and the ends of the pair of limiting plates 15 are clamped, so that the limiting plate 15 will not easily bend. Through the above structure, the bending of the limiting plate 15 can be reduced, and the loosening of the connecting pipe 12 caused by the rotation of the nut 13 can be further reduced.
[0027] As shown in Figures 1 to 4 The middle part of the mounting ring 14 is provided with a recess 5; the middle part of the recess 5 is fixedly connected with an elastic plate 51; during operation, after the sleeve ring 4 is slid to the corresponding position, the elastic plate 51 limits the position of the sleeve ring 4, and cooperates with the limiting block 41 to prevent the sleeve ring 4 from easily sliding. Through the above structure, the bending of the limiting plate 15 can be further reduced, and the loosening of the connecting pipe 12 caused by the rotation of the nut 13 can be further reduced.
[0028] As shown in Figures 1 to 4 The middle part of the sleeve ring 4 is fixedly connected with a plurality of reinforcing plates 6; the reinforcing plates 6 are fixedly connected to the inner side wall of the mounting ring 14; when the nut 13 is about to rotate and the limiting plate 15 expands outward, the limiting plate 15 will apply force to the sleeve ring 4 to deform the sleeve ring 4. At this time, the plurality of reinforcing plates 6 will resist the other planes of the nut 13 and prevent the sleeve ring 4 from deforming. Through the above structure, the rotation of the nut 13 caused by the deformation of the sleeve ring 4 can be reduced, and the loosening of the connecting pipe 12 caused by the rotation of the nut 13 can be further reduced.
[0029] As shown in Figure 3 The middle part of the bolt 16 is fixedly connected with a connecting rope 7; the other end of the connecting rope 7 is fixedly connected to the middle part of the mounting ring 14; through the above structure, when the bolt 16 is removed, the loss caused by the random placement of the bolt 16 can be reduced.
