[0037] like Figures 1 to 8 As shown, an embodiment of the present invention provides an anti-falling device for an oxygen inhaler, comprising an inhaler body 1, a socket 2 and an anti-falling device 3 for preventing the inhaler body 1 from falling off from the socket 2. The anti-falling device 3 is connected to the inhaler body 1 and the socket 2. The anti-falling device 3 comprises a connected positioning component and a pair of connecting components. The pair of connecting components are symmetrically arranged. The anti-falling device 3 is quickly positioned and connected to the inhaler body 1 through the positioning component, and is clamped to the inhaler body 1 through the connecting component, and is clamped and fixed to the socket 2 at the same time. The anti-falling device 3 provides a certain supporting force for the inhaler body 1, avoiding the dead weight of the inhaler body 1 increasing the burden on the connection between the inhaler body 1 and the socket 2, thereby increasing the stability between the inhaler body 1 and the socket 2, and reducing the risk of the inhaler body 1 falling off from the socket 2, causing damage or injuring patients and other personnel.

[0038] like Figure 2 The outer walls of both ends of the open snap ring 4 are connected with a clamping plate 7, and the clamping plate 7 is rotatably connected to the open snap ring 4 by a self-locking bolt 8, and the self-locking bolt 8 limits the rotation direction of the clamping plate 7 so that it can only rotate in one direction. Through the open snap ring 4 and the clamping plate 7 arranged in pairs, a total of four groups of clamping plates 7 are respectively in contact with the upper and lower side surfaces of the socket 2, and the four groups of clamping plates 7 are in a clamping shape to clamp the socket 2, and the self-locking effect of the clamping plate 7 by the self-locking bolt 8 is achieved to fix the anti-slip device 3 on the socket 2. The operation is simple and it can be adapted to sockets of different widths.

[0039] like Figures 4 to 6As shown, the outer side wall of the open snap ring 4 is symmetrically fixedly connected with two groups of mounting protrusions 10, and the side wall of the mounting protrusion 10 is provided with an assembly groove 11. The cross-section of the assembly groove 11 is a convex structure and the bottom is a square groove body. The clamping plate 7 includes a connecting portion 12, and one end of the connecting portion 12 is fixedly connected to a force-applying portion 13. The force-applying portion 13 is an S-shaped structure. An inlay groove 14 is provided at the bottom of the end of the force-applying portion 13. An anti-slip pad 9 is embedded in the inlay groove 14. The side wall of the anti-slip pad 9 is provided with several groups of adsorption grooves 24. The adsorption groove 24 is a hemispherical blind groove structure. The anti-slip pad 9 is made of rubber material. When 7 is clamped and fixed on the socket 2, the side of the anti-slip pad 9 with the adsorption groove 24 is in close contact with the socket 2. When the anti-slip pad 9 is squeezed and deformed, the adsorption groove 24 is also deformed and the air inside it is discharged. When the anti-slip pad 9 is completely in contact with the side wall of the socket 2, each group of adsorption grooves 24 forms a cavity between the side wall of the socket 2. There is an air pressure difference between the inside of the adsorption groove 24 and the external atmospheric pressure, which makes the anti-slip pad 9 adsorbed on the surface of the socket 2, thereby further increasing the fixing effect between the anti-slip device 3 and the socket 2, and further reducing the risk of the inhaler body 1 falling off from the socket 2.

[0040] like Figure 4 、 Figure 5 and Figure 8 As shown, the other end of the connecting portion 12 is fixedly connected to a cylindrical locking head 15, and a through groove 16 is provided at the bottom of the locking head 15. A plurality of locking tooth grooves 17 are evenly provided on the inner wall of the through groove 16. A pushing handle 18 is fixedly connected to one side of the locking head 15 relative to the connecting portion 12. The pushing handle 18 is an arc-shaped structure and is adapted to the palm of the human body. It is more comfortable for the operator to hold the pushing handle 18 and drive the pressing plate 7 to rotate as a whole. By setting the pressing plate 7, the pressing plate 7 is integrally formed of plastic through model casting. The connecting portion 12 and the force-applying portion 13 are both plastic thin plates, which can undergo a certain elastic deformation. When the anti-slip device 3 is clamped and fixed on the socket 2 by rotating the pressing plate 7, the bottom of the force-applying portion 13 The force-applying portion 13 contacts the upper or lower side wall of the socket 2 and deforms under the action of pressure, thereby increasing the contact area between the bottom of the force-applying portion 13 and the upper or lower side wall of the socket 2, thereby increasing the friction between the force-applying portion 13 and the socket 2, and preventing the anti-slip device 3 from falling off laterally from the socket 2. At the same time, due to the special S-shaped structure of the force-applying portion 13, when the force-applying portion 13 is compressed and deformed, the bottom surface of the force-applying portion 13 in contact with the socket 2 is subjected to a group of inclined reaction forces toward the bottom of the socket 2, thereby further preventing the anti-slip device 3 from falling off laterally from the socket 2. At the same time, by providing the anti-slip pad 9, the friction between the force-applying portion 13 and the socket 2 is further increased, thereby improving the anti-slip effect of the anti-slip device 3.

[0041] like Figures 5 to 7As shown, the self-locking bolt 8 includes a self-locking cap 20 embedded in the through groove 16. The cross-section of the self-locking cap 20 is a T-shaped structure. The maximum diameter of the self-locking cap 20 is larger than the inner diameter of the through groove 16. The side wall of the self-locking cap 20 is evenly ringed with multiple groups of locking teeth 21. The locking teeth 21 are adapted to the structure of the locking tooth groove 17. The locking teeth 21 are horn-shaped structures. The other side wall of the self-locking cap 20 is fixedly connected to a connecting rod 22 that passes through the through groove 16. The connecting rod 22 is away from the self-locking cap 2 One end of 0 is fixedly connected with a square plate butt plate 23, which is adapted to the assembly groove 11. By setting a self-locking bolt 8, when the pressing plate 7 is connected to the open snap ring 4 through the self-locking bolt 8, the self-locking cap 20 is embedded in the through groove 16, and the locking teeth 21 are engaged with the locking groove 17. The self-locking cap 20 can only be rotated in one direction, that is, the pressing plate 7 can only be rotated to move the end of the force-applying portion 13 toward the direction close to the socket 2. When reversed, due to the special locking teeth 21, the self-locking cap 20 can be rotated in one direction. When the locking nut 20 is moved to a certain distance, the locking teeth 21 are completely withdrawn from the locking groove 17, and the locking state of the pressing plate 7 is released by the self-locking bolt 8, and the force-applying portion 13 at the end of the pressing plate 7 lacks pressure to recover the deformation, and the clamping force of the force-applying portion 13 on the plug seat 2 disappears, and the pressing plate 7 can be removed from the plug seat 2.

[0042] The working principle provided by the utility model is that when using the inhaler body 1, the anti-slip device 3 is first connected to the inhaler body 1, the joint connected to the socket 2 on the inhaler body 1 is passed through the interior of the positioning ring 5, the open snap ring 4 is clamped on the inhaler body 1 and the two groups of open snap rings 4 are respectively located on both sides of the joint, after the anti-slip device 3 and the inhaler body 1 are installed, the joint on the inhaler body 1 is aligned with the socket on the socket 2 and inserted into the interior, when the joint of the inhaler body 1 is inserted into the socket of the socket 2 and ventilated, the operator can open his palm and simultaneously push the two groups of push handles 18 located on the same side of the inhaler body 1 inward, so that the pressing plate 7 is rotated around the self-locking bolt 8 as a whole, and when rotating During the process, a clicking sound can be heard as the locking teeth 21 deform and pass over the locking tooth grooves 17. Push the push handle 18 until a large resistance is encountered and the force-applying part 13 is folded to a large extent. At this time, the anti-slip pad 9 is compressed and flattened, and the volume of the adsorption groove 24 is reduced, and the internal gas is discharged. A cavity is sealed between the adsorption groove 24 and the side wall of the socket 2, and due to the pressure difference between the inside and outside of the adsorption groove 24, a negative pressure is formed inside the adsorption groove 24 to generate suction on the side wall of the socket 2, thereby increasing the friction between the force-applying part 13 and the socket 2, and two sets of symmetrical clamping plates 7 clamp the socket 2 and fix it. The two sets of clamping plates 7 on the other side of the open snap ring 4 are rotated in the same way to clamp the socket 2 and fix it.

[0043] When the inhaler body 1 needs to be pulled out from the socket 2, it is only necessary to press the end of the self-locking cap 20 to move the self-locking bolt 8 as a whole toward the mounting protrusion 10, thereby disengaging the locking teeth 21 from the locking grooves 17, releasing the locking effect of the self-locking bolt 8 on the clamping plate 7. When the clamping plate 7 is not locked, the deformation of the force-applying portion 13 is restored, driving the clamping plate 7 to reverse, thereby releasing the clamping effect on the socket 2, and then the inhaler body 1 can be pulled out.

[0044] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
