DETAILED DESCRIPTION

[0018] The embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary, and are intended to explain the present application, and cannot be understood as a limitation of the present application. In the description of the present application, it should be understood that the terms "upper", "lower", "front", "upper surface" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0019] Referring to Figures 1-6 The present application provides an embodiment: a medical inflatable air cushion, comprising an air cushion body 1, the air cushion body 1 is provided with a connecting hole 2, and a gas nozzle 3 is installed in the connecting hole 2; the gas nozzle 3 comprises a shell 30 and a gland 34 movably connected with the shell 30, a through hole 36 is formed on the bottom surface of the shell 30, and a spring 31 and a valve 32 are arranged in the shell 30; one side of the spring 31 abuts against the inner bottom surface of the shell 30, the other side of the spring 31 urges the valve 32 to abut against the gland 34, and an avoiding groove 37 is further arranged on the circumferential surface of the valve 32; the valve 32 is slidably connected with the guide hole 311 in the gland 34 through the guide rod 38 arranged thereon, and an exhaust groove 310 is further arranged on the inner wall surface of the guide hole 311.

[0020] As described above, since the valve 32 is in a normal state, the combined action of the air pressure in the air cushion body 1 and the spring 31 can reliably urge the valve 32 to abut against the gland 34, thereby reducing the leakage of the air source; when a user sits on the air cushion body 1, if the user feels that the pressure in the air cushion body 1 is too high, the guide rod 38 is pushed at this time to separate the valve 32 from the gland 34, at this time the air flow in the air cushion body 1 can be released. Based on this, the device has the advantages of convenient pressure regulation, that is, the user can sit on the air cushion body 1 to adjust the air pressure, thereby solving the problems existing in the prior art.

[0021] Further, since one side of the gland 34 is threadedly matched with the inner wall surface of the shell 30 through the provided external thread part 313, the connection of the gland 34 and the shell 30 is simple and convenient, and is stable and reliable after connection. At the same time, since the resisting part 39 is further provided on the external thread part 313, and the valve disc 32 is attached to the resisting part 39 through the resisting part 39, the valve disc 32 can be attached to the resisting part 39, and the resisting part 39 can further compress the spring 31, so that the reaction force of the spring 31 on the valve disc 32 is further improved, and the sealing between the valve disc 32 and the resisting part 39 is improved.

[0022] Further, since the limiting pin 35 is further provided on the inner wall surface of the shell 30, and one end of the limiting pin 35 is attached to the valve disc 32 after passing through the limiting pin 35, when the air pressure needs to be adjusted, the gland 34 can be counterclockwise rotated to move the external thread part 313 outward until the limiting pin 35 in the valve disc 32 is blocked, and the valve disc 32 and the resisting part 39 can be separated by continuing to rotate the gland 34, so that the air source can be released outward along the gap between the valve disc 32 and the resisting part 39. Therefore, the air pressure can be adjusted by rotating the gland 34, so that the air pressure adjustment is simple and convenient, and the flow of the air pressure released outward can be adjusted according to the need by controlling the gap between the valve disc 32 and the resisting part 39.

[0023] In order to improve the sealing between the valve disc 32 and the resisting part 39, the ring groove 312 is further provided on the resisting part 39, and the sealing ring 33 is further installed in the ring groove 312.

[0024] Further, since the number of the limiting pins 35 is equal to the number of the avoiding grooves 37, and the number of the limiting pins 35 is two and symmetrically arranged on the inner wall surface of the shell 30, the two limiting pins 35 can be used to prevent the valve disc 32 from moving outward, so as to avoid that the valve disc 32 breaks the limiting pin 35 when moving due to the excessive air pressure in the air cushion body 1. Specifically, when the valve disc 32 is installed, the valve disc 32 moves along the avoiding groove 37 along the limiting pin 35 until the valve disc 32 completely passes the limiting pin 35, and then the valve disc 32 is rotated to make the avoiding groove 37 deviate from the limiting pin 35.

[0025] In addition, since the air pressure in the air cushion body 1 can be adjusted by rotating the gland 34, after the end surface of the valve disc 32 is attached to the resisting part 39, the guide rod 38 is completely located in the guide hole 311, so that the air leakage of the air cushion body 1 caused by accidentally touching the guide rod 38 can be reduced.

[0026] The embodiments of the present application are described in detail in combination with the drawings, but the present application is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and variations of the embodiments can be made without departing from the principles and spirits of the present application, and still fall within the protection scope of the present application.
