[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figure 1 , Figure 2This utility model provides a self-closing valve lower housing that is easy to install, including a lower housing body 1; characterized in that: a base 11 is fixedly connected to the bottom end of the lower housing body 1; a ball socket 12 is formed on the side wall of the base 11; a main ball thread rod 13 is rotatably connected to the side wall of the ball socket 12; a support 14 is fixedly connected to the end of the main ball thread rod 13; a fastening nut 15 is threadedly connected to the middle of the support 14; an annular pressure block 16 is fixedly connected to the end of the fastening nut 15; a secondary ball thread rod 17 is rotatably connected to the inner side wall of the support 14; the secondary ball thread... A threaded post 18 is threadedly connected to the inner wall of rod 17; a fixing plate 19 is fixedly connected to the end of the threaded post 18; a threaded hole 101 is opened at the end of the fixing plate 19; during operation, when installing the lower housing body 1, the rotation effect of the main ball-head threaded rod 13 and the base 11 causes the lower housing body 1 to rotate within a certain angle range through the base 11, which facilitates docking with pipes in different directions in narrow spaces. After determining the rotation angle of the base 11, by tightening the fastening nut 15, the annular pressure block 16 will apply pressure to the main ball-head threaded rod 13, thereby increasing... By applying friction between the main ball thread rod 13 and the ball socket 12, the main ball thread rod 13 is fixed at the required angle and locked. The operator can flexibly adjust the angle of the lower housing body 1 according to actual needs, and then lock it with a locking device to facilitate docking with pipes in different directions. Then, according to the spatial distribution of the installation, the direction of the auxiliary ball thread rod 17 can be adjusted, and the height of the fixing plate 19 can be adjusted by rotating the threaded column 18 to adapt to the installation environment. Then, the fixing plate 19 can be installed and fixed by bolts and threaded holes 101, thus fixing the support feet and completing the fixed connection of the lower housing body 1. When installing the lower housing of the self-closing valve, this design first adjusts the angle of the lower housing through the ball joint to match the direction of the pipe, then tightens the nut to lock the ball joint, and then rotates the support feet and adjusts the height of the two support feet to make the lower housing adapt to the required level and height of the installation space. After fixing the support feet, the installation is completed. This universal positioning mounting seat design greatly reduces the installation difficulty, improves the accuracy of the installation position, and enhances the convenience of installation in narrow spaces.

[0027] Furthermore, such as Figure 1 , Figure 5As shown, the lower housing body 1 has fixed ring blocks 2 at both ends; the sidewalls of the fixed ring blocks 2 are provided with filling grooves 21 and sliding grooves 24; an airbag ring 22 is fixed to the inner sidewall of the filling groove 21; multiple sets of pressurizing points 23 are connected through the sidewalls of the airbag ring 22; pressure rings 25 are fixed to the sidewalls of the pressurizing points 23; a first spring 26 is fixed to the end of the pressure ring 25; a sleeve shell 27 is fixed to the end of the first spring 26; during operation, when external pipes are connected to both sides of the lower housing body 1, because the radius of the opening at the end of the sleeve shell 27 is smaller than the radius of the pipe connected to the lower housing body 1, when the external pipe is threadedly connected to the lower housing body 1, the opening of the sleeve shell 27 will adhere to the external pipe, and as the external pipe... The deeper connection causes the sleeve shell 27 to move closer to the fixed ring block 2. At this time, the first spring 26 is subjected to pressure and generates a rebound force on the pressure ring 25. The pressure ring 25 squeezes the pressurization point 23. When the pressurization point 23 is squeezed, the internal space is reduced, and the gas inside enters the airbag ring 22, thereby expanding the airbag ring 22. As the airbag ring 22 expands, it can fill the gap between the threaded connection point of the external pipe and the lower shell body 1, thereby achieving automatic fastening and sealing of the pipe connection. When the pipe is connected, the automatic fastening and sealing device automatically fills the gap at the pipe connection to achieve a fastening and sealing effect, thereby improving the sealing tightness of the pipe connection and reducing the possibility of gas leakage.

[0028] Furthermore, such as Figure 4 As shown, the bottom end of the fixing plate 19 is provided with a placement groove 3; an adhesive sheet 31 is fixedly attached to the side wall of the placement groove 3; during operation, after determining the fixed position of the fixing plate 19, it is placed on the fixed plane. At this time, the adhesive sheet 31 adheres to the fixed plane, temporarily stabilizing it, which facilitates the use of bolts to fix it to the fixed plane. This design provides a temporary stabilizing effect for the fixing device through the set adhesive structure, which facilitates bolt connection positioning and improves the fixing speed.

[0029] Furthermore, such as Figure 3 As shown, the inner wall of the base 11 has multiple sets of telescopic grooves 4; a second spring 41 is fixedly connected to the inner wall of the telescopic groove 4; a rubber washer 42 is fixedly connected to the end of the second spring 41; during operation, the second spring 41 and the rubber washer 42 form an elastic damping structure, which effectively reduces the noise and loosening risk caused by vibration during equipment operation. This design reduces the vibration effect through the elastic damping structure, thereby improving the overall reliability and service life of the equipment.

[0030] Furthermore, such as Figure 2As shown, a magnetic groove block 5 is fixedly connected to the side wall of the ball socket 12; a magnetic ring 51 is fixedly connected to the side wall of the annular pressure block 16; and a magnetic ring 51 is slidably connected to the inner side wall of the magnetic groove block 5. During operation, when the annular pressure block 16 slides upward, it will drive the magnetic ring 51 to slide into the magnetic groove block 5. At this time, the magnetic attraction effect generated by the magnetic groove block 5 and the magnetic ring 51 can improve the stability of the annular pressure block 16 when applying pressure to the main ball thread rod 13. This design can improve the fixing effect through the magnetic attraction structure, thereby improving the stability of pressure application.

[0031] Furthermore, such as Figure 5 As shown, a rubber ring 6 is fixed to the end of the fitting shell 27. During operation, the rubber ring 6 can enhance the friction between the fitting shell 27 and the external pipe. This design enhances the friction and improves the starting stability of the automatic fastening and sealing device, thereby increasing the sealing speed.

[0032] Working principle: During the installation of the lower housing body 1, the rotation of the main ball-head threaded rod 13 and the base 11 causes the lower housing body 1 to rotate within a certain angle range, facilitating docking with pipes in different directions within narrow spaces. After determining the rotation angle of the base 11, tightening the locking nut 15 causes the annular pressure block 16 to apply pressure to the main ball-head threaded rod 13, thereby increasing the friction between the main ball-head threaded rod 13 and the ball socket 12, fixing the main ball-head threaded rod 13 at the required angle and locking it in place. The operator can flexibly adjust the angle of the lower housing body 1 according to actual needs, and then... The locking device secures the device, facilitating connection with pipes in different directions. The direction of the auxiliary ball-head threaded rod 17 can be adjusted according to the installation space, and the height of the fixing plate 19 can be adjusted by rotating the threaded column 18 to adapt to the installation environment. Subsequently, the fixing plate 19 is installed and fixed by bolts connecting it to the threaded hole 101, thus securing the support legs and completing the fixed connection to the lower housing body 1. When connecting external pipes to both sides of the lower housing body 1, because the radius of the opening at the end of the sleeve shell 27 is smaller than the radius of the pipe connected to the lower housing body 1, the opening of the sleeve shell 27 is... The gas will adhere to the external pipe. As the external pipe is connected deeper, the sleeve shell 27 moves closer to the fixed ring block 2. At this time, the first spring 26 is subjected to pressure and generates a rebound force on the pressure ring 25, which in turn squeezes the pressurization point 23. When the pressurization point 23 is squeezed, the internal space is reduced, and the gas inside enters the airbag ring 22, thereby expanding the airbag ring 22. As the airbag ring 22 expands, it can fill the gap between the threaded connection point of the external pipe and the lower shell body 1, thereby achieving automatic fastening and sealing of the pipe connection. After determining the fixed position of the fixing plate 19, it is placed on the fixed plane. At this time, through The adhesive sheet 31 adheres to the fixed plane, temporarily stabilizing it and facilitating its connection to the fixed plane with bolts. The second spring 41 and the rubber washer 42 form an elastic shock-absorbing structure, effectively reducing noise and loosening risks caused by vibration during equipment operation. When the annular pressure block 16 slides upward, it drives the magnet ring 51 to slide into the magnet groove block 5. At this time, the magnetic attraction between the magnet groove block 5 and the magnet ring 51 can improve the stability of the annular pressure block 16 when applying pressure to the main ball thread rod 13. The rubber ring 6 can enhance the friction between the sleeve shell 27 and the external pipe.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
