[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0020] The following is a reference to the appendix. Figure 1 To be continued Figure 4 This invention describes a sealing joint for a flexible pipe.

[0021] like Figure 1 and Figure 3 As shown, the sealing joint of the flexible pipe in this utility model includes a joint body 1 and connecting seats 2 disposed at both ends of the joint body 1. The flexible pipe passes through the joint body 1 along the connecting seats 2. A sealing seat 4 is provided inside the joint body 1. A pressing seat 5 is provided at both ends of the sealing seat 4. An adjusting seat 6 is provided on the side of the two pressing seats 5 away from the sealing seat 4. The adjusting seat 6 is connected between the joint body 1 and the connecting seat 2. The adjusting seat 6 abuts against the pressing seat 5. A pipe body 3 is provided inside the pressing seat 5. The ends of the pipe body 3 are folded outward and sleeved on the ends of the pressing seat 5. The ends of the pressing seat 5 abut against the sealing seat 4. The ends of the pipe body 1 are pressed between the sealing seat 4 and the pressing seat 5 so that the sealing seat 4 and the pressing seat 5 cooperate to press the flexible pipe.

[0022] The flexible pipe is pressed down by the cooperation of the sealing seat 4 and the pressing seat 5. The sealing seat 4 and the pressing seat 5 adopt a frustum-shaped structure for fitting, which makes the fit tighter and the sealing better, thus achieving a sealed connection of the flexible pipe. The pressing seat 5 is fixed by the adjusting seat 6. The adjusting seat 6 is fixed between the joint and the connecting seat 2 during installation, and the fixing method is stable and reliable.

[0023] Furthermore, such as Figure 2 and Figure 3As shown, the connecting seat 2 is connected to both ends of the connector body 1 via flanges; the sealing seat 4 is provided with an inner sealing surface 41, and the pressing seat 5 is provided with an outer sealing surface 51 at one end, with the inner sealing surface 41 and the outer sealing surface 51 having the same inclination angle; the pipe body 3 passes through the pressing seat 5, and the end of the pipe body 3 is turned outward and fitted onto the outer sealing surface 51 so that the end of the pipe body 3 is pressed between the inner sealing surface 41 and the outer sealing surface 51.

[0024] In this embodiment, preferably, the connector body 1 has flange structures on both sides, and the connecting seat 2 has a flange at its end, so that the connecting seat 2 is connected to the flange structure of the connector body 1 through the flange. At the same time, the flexible pipe to be connected passes through the connecting seats 2 on both sides, and the end of the flexible pipe passes through the connector body 1 for connection and sealing.

[0025] A sealing seat 4 is fixedly installed in the connector body 1. After the pipe body 3 passes through the connecting seat 2, it is fitted onto one end of the clamping seat 5. When in use, the clamping seat 5 is pressed against the sealing seat 4, pressing the end of the pipe body 3 between the sealing seat 4 and the clamping seat 5, thereby achieving a sealing effect.

[0026] The clamping seat 5 is fixed by the adjusting seat 6. The adjusting seat 6 is fixed between the connector body 1 and the connecting seat 2 during installation to ensure the stable setting of the clamping seat 5, thereby ensuring the sealing between the clamping seat 5 and the sealing seat 4.

[0027] The two ends of the sealing seat 4 are matched with the pressing seat by setting the inner sealing surface 41. The outer sealing surface 51 on the pressing seat 5 is in contact with the inner sealing surface 41. Preferably, the inner sealing surface 41 and the outer sealing surface 51 have the same inclination angle, and the two sealing surfaces can be completely in contact with each other.

[0028] After the end of the pipe body 3 is folded outward, it is fitted onto the outer sealing surface 51, and as the pressing seat 5 moves, it is pressed between the inner sealing surface 41 and the outer sealing surface 51; the frustum-shaped inclined surface can press tightly when it is in contact, and as the pressing seat 5 moves toward the sealing seat 4, the two fit together more tightly, resulting in a better sealing effect.

[0029] In a preferred embodiment, the clamping seat 5 and the adjusting seat 6 are connected by a sliding connection, which allows the distance between them to be changed and the two to be disassembled. This not only allows the clamping seat 5 to be replaced to change its diameter, making it suitable for pipes of different diameters, but also allows the distance between the clamping seat 5 and the adjusting seat 6 to be adjusted, making it suitable for pipes of different wall thicknesses and ensuring that the joint has higher applicability.

[0030] Furthermore, such as Figure 3 As shown, a screw cylinder 62 is provided in an annular shape at the end of the adjusting seat 6, and the screw cylinder 62 is connected to the adjusting seat 6 through a rotating shaft; a screw 52 corresponding to the screw cylinder 62 is provided on the clamping seat 5 so that the screw 52 is inserted into the screw cylinder 62.

[0031] In this embodiment, preferably, the end of the clamping seat 5 is connected to the end of the adjusting seat 6 via a screw 52 and a screw cylinder 62. The screw cylinder 62 can rotate to cooperate with the screw 52, ​​thereby winding in or out of the screw 52, ​​so as to achieve the purpose of adjusting the position of the adjusting seat 6 and the clamping seat 5.

[0032] Furthermore, such as Figure 4 As shown, multiple fixing pieces 61 are spaced apart along the circumference of the adjusting seat 6, and multiple limiting grooves 11 are correspondingly provided at the end of the connector body 1. The fixing pieces 61 are correspondingly engaged in the limiting grooves 11 and pressed by the connecting seat 2. The connecting seat 2 is provided with an annular pressing groove 21, which is engaged on the side of the fixing piece 61 away from the limiting groove 11 to limit the fixing piece 61. A sealing groove 12 is provided on the end face of the connector body 1, and a buffer strip is provided in the sealing groove 12 to provide a buffering effect between the connector body 1 and the connecting seat 2.

[0033] In this embodiment, preferably, during the installation of the adjusting seat 6, it is fixed between the connector body 1 and the connecting seat 2. The peripheral side of the adjusting seat 6 is locked in the limiting groove 11 on the end face of the connector body 1 by the fixing piece 61. After locking, the position of the adjusting seat 6 can be restricted, so that it can only move axially and cannot deflect, thereby avoiding the radial force on the pressing seat 5 and affecting its structural state.

[0034] A sealing groove 12 is also provided on the end face of the connector body 1. By setting a buffer strip in the sealing groove 12, a buffer effect is achieved when the connector body 1 and the connecting seat 2 are connected, so as to avoid direct rigid contact between the two. This ensures that the connecting seat 2 can provide sufficient pressure to the adjusting seat 6 while avoiding rigid compression between it and the connector body 1, which would cause structural damage.

[0035] The end of the connecting seat 2 is provided with a pressing groove 21. The pressing groove 21 can be locked on the outside of the fixing plate 61 and provide pressing force to the fixing plate 61 when the connecting seat 2 is fixed to the connector body 1, thereby maintaining the tight fit between the pressing seat 5 and the sealing seat 4 and ensuring the sealing performance.

[0036] Based on the sealing joint of flexible pipe, this utility model changes the distance between the sealing seat 4 and the pressing seat 5 by adjusting the position between the adjusting seat 6 and the pressing seat 5, so as to be suitable for use with pipes of different sizes. Different pressing seats 5 can also be replaced to be suitable for use with pipes of different diameters.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
