detailed description

With regard to the structure and composition of the gas transmission conversion device for the air-bed airbag of the present invention, and the effects thereof, a preferred embodiment of the case will be described in detail as follows in conjunction with the drawings.

Please refer to Fig. 1, Fig. 2 and Fig. 3. The air transmission conversion device of the air bed airbag in this case mainly includes a first body 1, a second body 2 and an outer body 3, and also includes a spring 4 , a cover body 5 and a stud 6; the above components can be assembled into one body. Wherein, the first body 1 is slightly semi-cylindrical, and one side is provided with a first pipe body 11, a second pipe body 12 and a third pipe body 13 which are all through-shaped, and one or more than one The lock part 14; the center of the other side of the first body 1 is provided with a shaft 16, and the shaft 16 is provided with a second groove 18, and a second oil seal 181 is arranged in the second groove 18; and The ring side of the first body 1 is provided with a positioning block 15 outward, and the ring side of the first body 1 is further provided with a first groove 17, and a first oil seal 171 is arranged in the first groove 17; the second body 2 , can be used to assemble with the first body 1, the second body 2 is slightly semi-cylindrical, a chamber 20 is provided adjacent to the side of the first body 1, and a central inner edge of the chamber 20 is provided with a shaft hole 21, The inner edge of the chamber 20 is provided with a perforation 22 and one or more than one protrusion 24, the aforementioned perforation 22 is provided with a plug body 23; the structure of the second body 2 on the edge of the chamber 20 forms a first recessed area 25, the first recessed area 25 is adjacent to a blocking area 26, and next to the blocking area 26 is adjacent to a second recessed area 27; the aforementioned positioning block 15 of the first body 1 can be used to move on the first Between the recessed area 25 or the second recessed area 27; the second body 2 is provided with a space 28 relative to the other side of the chamber 20; the outer body 3 is arranged on the outer side of the first body 1, the outer The main body 3 is provided with a first opening 31, a second opening 32 and a third opening 33, and each of the first opening 31, the second opening 32 and the third opening 33 can be used to communicate with the first opening 33 of the first main body 1 respectively. The tube body 11, the second tube body 12 and the third tube body 13 are socketed; in addition, the outer body 3 is provided with one or more lock holes 34, and each lock hole 34 can be connected with the lock portion 14 of the first body 1 Sleeve, and provide a screw 35 for locking; the spring 4 is assembled in the space 28 of the second body 2, the cover 5 can be used to be sleeved on the outside of the spring 4, and the stud 6 is used for wearing After being locked by the cover body 5 and the spring 4, it is arranged on the shaft post of the first body.

When the case is to be assembled, the outer body 3 is covered on one side of the first body 1, and the screw 35 is used to pass through the lock hole 34 of the outer body 3 and the lock portion 14 of the first body 1, and the The outer body 3 is combined with the first body 1; then, the stud 6 is passed through the cover body 5, the spring 4, the shaft hole 21 of the second body 2, and finally screwed into the shaft column 16 of the first body 1, that is, The combination of the cover body 5 , the spring 4 , the second body 2 and the first body 1 is completed.

One of the configuration methods that can be implemented in this case is that the first pipe body 11 and the second pipe body 12 are respectively connected with an air delivery pipe 8 and an air intake pipe 7 (as shown in Figure 3, Figure 4a and Figure 4b), wherein, the The outer end of the air intake pipe 7 is connected to the pump (not shown), and the air delivery pipe 8 is connected to the airbag (not shown in the figure). Under normal conditions, the gas transmission conversion device provides the air transmission between the intake source and the airbag. That is to say, the gas enters from the inlet pipe 7 and enters the chamber 20 through the second pipe body 12. Due to the setting of the bump 24, the chamber 20 can provide gas to pass through. At this time, both the first pipe body 11 and the second pipe body 12 It is misaligned with the plug body 23, and the inner end of the third tube body 13 is closed by the plug body 23, so the gas entering the chamber 20 can only be transferred into the first tube body 11, and finally sent out by the gas delivery pipe 8 and enters the external connection. The inside of the airbag achieves the inflation effect.

When the air bag is to be exhausted in this case, please cooperate with Fig. 5 and Fig. 6 to pull the second body 2 outwards, and compress the spring 4, especially to allow the first recessed area 25 to move out of the contact with the protrusion 15. contact, and then rotate the second body 2 (as shown in Figure 7), so that the blocking area 26 can pass over the protrusion 15, and finally form the engagement relationship between the second recessed area 27 and the protrusion 15 (as Figures 8a and 8b) ; At this time, the air originally entering the second pipe body 12 by the air intake pipe 7 will not be able to pass because the inside is blocked by the plug body 23; , because the first pipe body 11 communicates with the chamber 20 inside, and the chamber 20 is connected with the third pipe body 13, so the air in the air delivery pipe 8 will turn to flow to the third pipe body 13 and finally be discharged. To achieve the purpose of rapid exhaust.

The aforementioned air delivery pipe 8 of this case can be connected to any air bag of the air mattress, such as a small air bag for turning over or a side rail. In addition, the number of the first tubes 11 in the structure of the present case can be increased according to the need, so as to simultaneously correspond to the air delivery or exhaust needs of a plurality of airbags.

Although the present invention has been described with the aid of the foregoing embodiments, the forms and details can still be changed without departing from the spirit of the present invention, and can be understood by those skilled in the art. The aforementioned preferred embodiment of this case is only one of the modes that can be specifically implemented by virtue of the principle of this case, but it is not limited thereto, and should be defined in accordance with the claims.
