The second end extends to the outside of the expansion section in a direction away from the reduction section. There are two second connecting posts, which correspond to the two ends of the side rod respectively. The ends of the side rod and the corresponding second connecting posts are provided with second mounting holes. The second screw is threaded into the second mounting hole.

[0012] Furthermore, each of the two ends of the side rod is provided with a third connecting post. The end of the second connecting post has a conical positioning platform. The end face of the third connecting post has a conical positioning groove for the conical positioning platform of the corresponding second connecting post to enter. The conical positioning platform of the second connecting post is set in the conical positioning groove of the corresponding third connecting post.

[0013] Furthermore, the outer side of the reduced diameter section has several pairs of second reinforcing ribs, which are arranged parallel to the central axis of the mounting base.

[0019] Furthermore, the inflation piping assembly has two parts, which are symmetrically arranged on both sides of the box body.

[0020] The advantages of this utility model are:

[0021] The air pump control box of this utility model has a silencer installed on the main air pipe, and the branch air pipes and silencer are fixed in the box body by a vertical plate. One end of the branch air pipe is connected to the main air pipe by an air valve, and the other end is fixed to the box body by a quick-release tee. This design can effectively reduce the air pipe vibration caused by gas flow and effectively reduce noise. By installing air pressure sensors on the quick-release tees of each branch air pipe, the pressure in each branch air pipe can be detected in real time, which is conducive to real-time adjustment of inflation and deflation.

[0022] This invention reduces the contact area and sealing between the air pump and the mounting base by creating a cut slit in the mounting base, thereby weakening the vacuum adsorption effect caused by excessively tight surface contact. By placing the two connecting plates of the mounting base on both sides of the cut slit, the defect of weakened local structural strength caused by the cut slit in the mounting base can be effectively compensated. Furthermore, the two connecting plates are fastened to the first connecting post by the first screw, and the clamping force of the mounting base on the air pump can be adjusted by adjusting the tightness of the first screw.

[0023] This invention effectively reduces the radial dimension of the mounting base by placing the connecting plate on the outer wall of the reduced diameter section. The second end of the side rod on the side of the mounting base away from the connecting plate extends outward to the outer side of the expanded diameter section, increasing the torque on the side of the mounting base in the expanded diameter section. This compensates for the uneven force on both sides of the mounting base caused by placing the connecting plate on the reduced diameter section, thus achieving a stable assembly of the mounting base.

[0024] This utility model achieves rapid positioning between the first mounting hole on the connecting plate of the mounting base and the first mounting hole on the first connecting column, and between the second mounting hole on the third connecting column of the mounting base and the second mounting hole on the second connecting column, by cooperating with the tapered positioning platform on the second connecting column of the side rod. It also limits the installation position of the mounting base to prevent the mounting base from shifting or deviating.

[0025] This invention improves the connection strength between the reduced diameter section and the expanded diameter section by setting a second reinforcing rib on the outside of the reduced diameter section, thereby enhancing the structural strength and stability of the mounting base.

[0026] This utility model has a rib positioning groove in the mounting seat groove. When assembling the mounting seat, the second reinforcing rib is inserted into the rib positioning groove to limit the installation position of the mounting seat in the mounting seat and prevent the mounting seat from rotating in the mounting seat during installation.

[0027] In this invention, the branch air pipe and the silencer are respectively set in the air pipe receiving groove or the silencer mounting hole of the upright plate, which limits the branch air pipe and the silencer to avoid mutual interference. The upright plate is directly inserted into the upright plate mounting groove, making the installation and operation simple and convenient.

[0028] The upright plate of this utility model uses a locking block and a locking groove to reinforce and limit the upright plate, thereby effectively preventing the upright plate from shaking in the upright plate mounting groove.

[0029] The tee connector of this utility model, through the cooperation of the side plate, top plate and partition plate, on the one hand, the quick-release tee does not need to be installed in a narrow box. Instead, the quick-release tee can be installed on the tee connector outside the box, and then the side plate of the tee connector can be installed in the side plate receiving groove of the box, which is very convenient. On the other hand, the partition plate is used to separate the quick-release tees to avoid mutual interference.

[0030] The present invention has two air tube components, which are suitable for independent adjustment of the left and right sides of a double mattress with two air bladder groups. The two air tube components are symmetrically arranged in the box, which can keep the center of gravity of the air pump control box in the middle of the box, which is conducive to the stable placement of the control box.

[0041] This embodiment provides an air pump control box, such as Figure 1-7 As shown, it includes a box body 1 and two inflation tube assemblies disposed within the box body 1. It is suitable for independent adjustment of the left and right sides of a double mattress with two airbag groups. The two inflation tube assemblies correspond to the two airbag groups of the double mattress and control inflation and deflation separately. The box body 1 has a component assembly cavity inside, and the top of the box body 1 has an opening for component assembly. The inflation tube assemblies are symmetrically arranged on both sides of the assembly cavity of the box body 1, which can keep the center of gravity of the inflation pump control box in the middle of the box body, which is conducive to the stable placement of the control box.

[0042] The inflation piping assembly includes an air pump 2, a main air pipe 4, three branch air pipes 6, a silencer 7, and three pressure sensors 12. The air pump 2 is installed inside the housing 1 via a mounting base 3. The main air pipe 4 is connected to and communicates with the air pump 2. The three branch air pipes 6 and the silencer 7 are installed inside the housing 1 via a vertical plate 8 and are connected to and communicate with the main air pipe 4 via an air valve 5. The side of each branch air pipe 6 away from the main air pipe 4 is installed on the housing 1 via a quick-release tee 9 and communicates with the outside of the housing 1. The three pressure sensors 12 correspond one-to-one with each branch air pipe 6. Each pressure sensor 12 is installed inside the housing 1 and is connected to the quick-release tee 9 of the corresponding branch air pipe 6 via a connecting pipe 12, and communicates with the corresponding branch air pipe 6 via a connecting pipe 11 and the quick-release tee 9.

[0043] In this embodiment, as Figure 5 As shown, the mounting base 3 is a stepped cylindrical structure formed by the cooperation of an expanding section 301 and a reducing section 302. The mounting base 3 has a pump assembly cavity in the middle that matches the shape of the air pump 2. The air pump 3 is inserted into the air pump assembly cavity. A cut slit 304 is opened on the mounting base 3, extending axially through the expanding section 301 and the reducing section 302. By opening the cut slit on the mounting base, the contact area and sealing between the air pump and the mounting base are reduced, thereby weakening the vacuum adsorption effect caused by excessively tight surface contact. Furthermore, by placing the two connecting plates of the mounting base on both sides of the cut slit...

[0044] Two connecting plates 303 extend radially outward on the outer wall of the reduced diameter section 302 of the mounting base 3. The two connecting plates 303 are located on both sides of the cut slit 304 of the reduced diameter section 302. The side of the connecting plate 303 is connected to the end face of the expanded diameter section 301 near the reduced diameter section 302, which can effectively make up for the defect of weakened local structural strength caused by the cutting slit 304 of the mounting base 3.

The side rod 305 is connected to the reduced section 302 through a first reinforcing rib 307. The side rod 305, the first reinforcing rib 307 and the mounting base 3 are integrally formed. The second end extends to the outside of the expanded section 301 in a direction away from the reduced section 302, increasing the force torque on the expanded section side of the mounting base 3, thereby compensating for the uneven force on both sides of the mounting base 3 caused by setting the connecting plate 303 on the reduced section 303, and realizing the stable assembly of the mounting base 3.

[0046] The reduced diameter section 302 of the mounting base 3 has two pairs of second reinforcing ribs 308 on its upper and lower sides. The second reinforcing ribs 308 are arranged parallel to the central axis of the mounting base 3. One side of the second reinforcing rib 308 is connected to the reduced diameter section 302, and the other side is connected to the end face of the expanded diameter section 301 near the reduced diameter section 302. By setting the second reinforcing ribs 308 on the outside of the reduced diameter section 302, it is beneficial to improve the connection strength between the reduced diameter section 302 and the expanded diameter section 301, thereby improving the structural strength and stability of the mounting base 3.

[0047] The housing 1 has a mounting slot 101 that matches the mounting base 3. The mounting slot 101 has a rib positioning slot 102. The mounting base 3 is set in the mounting slot 101. The second reinforcing rib 308 on the lower side of the reduced diameter section 302 is inserted into the rib positioning slot 102 to limit the installation position of the mounting base 3 in the mounting slot 101 and prevent the mounting base 3 from rotating in the mounting slot 101 when it is installed.

[0048] The mounting base 101 has a first connecting post 103 and a second connecting post 104 on both sides. There are two first connecting posts 103.

The two connecting plates 303 have first mounting holes that cooperate with the first connecting posts 103. Each first screw passes through the first mounting hole of the two connecting plates 303 and is threaded into the first mounting hole of the corresponding first connecting post 103. The two connecting plates 303 are fastened to the first connecting posts 103 by the first screws. The clamping force of the mounting base 3 on the air pump 2 can be adjusted by adjusting the tightness of the first screws.

[0049] There are two second connecting posts 104, corresponding to the two ends of the side rod 305 respectively. Each end of the side rod 305 is provided with a third connecting post 306. Each third connecting post 306 is installed on the second connecting post 104 by a second screw. The third connecting post 306 and the corresponding second connecting post 104 have a second mounting hole. The second screw passes through the second mounting hole of the third connecting post 306 and is threaded into the second mounting hole of the second connecting post 104. In this embodiment, the end of the second connecting post 104 has a conical positioning platform 1041, and the end face of the third connecting post 306 has a conical positioning groove for the conical positioning platform 1041 corresponding to the second connecting post 104 to enter. The conical positioning platform 1041 of the second connecting post 104 is set in the conical positioning groove corresponding to the third connecting post 306, so as to realize the rapid positioning between the first mounting hole on the connecting plate 303 of the mounting base 3 and the first mounting hole on the first connecting post 103, and the second mounting hole on the third connecting post 306 of the mounting base and the second mounting hole on the second connecting post 104, and limit the installation position of the mounting base 3 to prevent the mounting base 3 from shifting or deviating.

The bottom of the upright plate 8 is inserted into the corresponding upright plate mounting slot 107, which facilitates assembly. Two snap-fit ​​blocks 803 extend outward from the middle of the upright plate 8. The housing 1 has two snap-fit ​​grooves 108 corresponding to the snap-fit ​​blocks 803. When the upright plate 8 moves and inserts into the upright plate mounting slot 107, the snap-fit ​​blocks 803 move synchronously with the upright plate 8 and insert into the corresponding snap-fit ​​grooves 108, which strengthens and limits the upright plate 8, thereby effectively preventing the upright plate 8 from shaking in the upright plate mounting slot 107.

[0051] like Figure 6 As shown, the top of the upright plate 8 has six air pipe receiving slots 801 that correspond one-to-one with the branch air pipes of the two inflation pipeline assemblies.

The upright plate 8 has two muffler mounting holes 802 for the mufflers 7 of the two inflation pipeline assemblies to pass through respectively. The ends of the mufflers 7 are inserted into the corresponding muffler mounting holes 802.

[0052] In this embodiment, the quick-release tees 9 of the three branch air pipes 6 of each inflation pipeline assembly are installed on the housing 1 via a tee connector 10. For example...

The top plate 1002 is positioned above the quick-release tee 9 inside the box 1 and is connected to the side wall of the side plate 1001. Two partition plates 1003 are positioned below the top plate 1002 and are spaced apart from the quick-release tee 9 of the three branch bronchial tubes. The quick-release tee 9 of each branch bronchial tube is connected to the adjacent partition plate 1003 by a third screw. Each quick-release tee 9 has a third mounting hole that mates with the partition plate 1003. The third screw passes through the third mounting hole of the quick-release tee 9 and is threaded into the third mounting hole on the partition plate 1003.
