[0025] The following will be combined with the attached Figure 1-7 The embodiments of the present utility model will be described in detail.
[0026] Example 1
[0027] In the fresh air system, when the fresh air coming out of the fresh air distributor passes through the connection between the air distribution valve 2 and the air outlet pipe 4, due to the influence of air flow, the air outlet pipe 4 and the air distribution valve 2 will constantly shake during operation. Over time, it is easy to cause the connection between the air outlet pipe 4 and the air distribution valve 2 to be loose and leak air at this connection, and in severe cases, the two will even separate.
[0028] To solve the above problems, on the basis of the existing connection structure, Figure 4 For the connection structure 3 of the present application, a connection mechanism with a sealing function is designed for the fresh air distributor to make the air distribution valve 2 and the air outlet pipe 4 on the fresh air distributor be tightly connected. Therefore, as Figure 3 shown, this embodiment provides a fresh air distributor, including an air distribution box 1 and an air distribution valve 2. A connection structure 3 is provided at the end of the air distribution valve 2. As Figure 4 and 5 shown, the connection structure 3 includes an outer sleeve 5 and an inner sleeve 6. The outer sleeve 5 is sleeved outside the inner sleeve 6. The connection structure 3 is used to externally connect the air outlet pipe 4. The outer sleeve 5 includes a first half-ring 51 and a second half-ring 52. One end of the first half-ring 51 is hinged and fixed to the air distribution valve 2 with the other end of the second half-ring 52. The other end of the first half-ring 51 and the other end of the second half-ring 52 are tightly connected by a locking member 7. It can be understood that the outer sleeve 5 is composed of two symmetrically arranged half-rings, where one end of the two half-rings is hinged and the other end is connected by a locking member 7 such as a bolt, and at the hinged end, the hinge shaft is welded and fixed to the air distribution valve 2. The inner sleeve 6 includes a first sleeve ring 61 arranged inside the first half-ring 51 and a second sleeve ring 62 arranged inside the second half-ring 52. The first sleeve ring 61 and the second sleeve ring 62 are used to clamp the air distribution valve 2 and the air outlet pipe 4. It can be understood that since the first sleeve ring 61 and the second sleeve ring 62 need to sleeve the air distribution valve 2 and the air outlet pipe 4, and the air outlet pipe 4 is often a corrugated pipe, the first sleeve ring 61 and the second sleeve ring 62 are preferably made of an elastic rubber material. A first sealing member 611 is provided at the end of the first sleeve ring 61, and a second sealing member 612 that cooperates with the first sealing member 611 is provided at the end of the second sleeve ring 62. The first sealing member 611 and the second sealing member 612 cooperate with each other to tightly connect with the air outlet pipe 4.
[0029] In this embodiment, in order to better adapt to air outlet pipes 4 of different sizes and ensure the sealing effect, both the first sealing member 611 and the second sealing member 612 are made of elastic materials. When using this connection structure 3, the air distribution valve and the air outlet pipe 4 are both sleeved inside the first sleeve ring 61 and the second sleeve ring 62, and the two are respectively located at both ends of the first sleeve ring 61 and the second sleeve ring 62.
[0030] During installation, open the first half-ring 51 and the second half-ring 52, place the air outlet pipe 44 in the chamber formed by enclosing the first set of rings 61 and the second set of rings 62, and then close the first half-ring 51 and the second half-ring 52 and fasten them with fasteners.
[0031] Embodiment 2
[0032] Considering that gas is likely to leak out from the connection between the first set of rings 61 and the second set of rings 62, therefore, on the basis of Embodiment 1, as Figure 1 and Figure 2 shown, the first seal 611 is provided with a protrusion 8, and the second seal 612 is provided with a groove 9 that cooperates with the protrusion 8; the protrusion 8 is used to insert into the groove 9 so that the protrusion 8 and the groove 9 are tightly fitted. It can be understood that during the process of gas escaping outward, it escapes from the inside to the outside along the "bow" - shaped path formed by the butt - joint of the protrusion 8 on the first seal 611 and the groove 9 on the second seal 612. This not only increases the length of the path but also, compared with the straight - line path, increases the difficulty of escape.
[0033] For reference, the first seal 611 and the protrusion 8 can be an integral structure, or a fixed structure formed by welding the protrusion 8 on the first seal 611, or the protrusion 8 can be detachably connected to the first seal 611; at this time, the first seal 611 and the first set of rings 61 can be an integral structure or a split structure. Similarly, the second seal 612 and the groove 9 can also be an integral structure; the second seal 612 and the second set of rings 62 can be an integral structure or a split structure.
[0034] Embodiment 3
[0035] In order to further improve the sealing performance of the connection structure 3 and further prevent gas from leaking out from the connection between the first set of rings 61 and the second set of rings 62, therefore, on the basis of Embodiment 2, the protrusion 8 is multiple, and the number of the grooves 9 is equal to that of the protrusion 8; and the multiple protrusions 8 are arranged at equal intervals in the radial direction of the first seal 611, and the positions of the multiple grooves 9 on the second seal 612 correspond to the protrusions 8 one by one.
[0036] For reference, the protrusion 8 can be two, three or even more. Correspondingly, the number of the grooves 9 is the same as that of the protrusion 8, and the positions of the grooves 9 correspond to the protrusions 8 one by one. In this way, after the protrusion 8 and the groove 9 cooperate, they form a path similar to an "S" shape, further increasing the length of the gas escape path and the difficulty of escape.
[0037] Embodiment 4
[0038] Since the entire connecting device is composed of two symmetrical parts, gas is likely to escape along the connection between the two symmetrical parts. Therefore, on the basis of Embodiment 3, in order to further enhance the sealing performance, as Figure 5 shown, a first gasket 10 is connected to the inner wall of the end of the first half-ring 51 facing the second half-ring 52; a second gasket 10' that cooperates with the first gasket 10 is connected to the inner wall of the end of the second half-ring 52, and the first gasket 10 and the second gasket 10' are in mutual contact.
[0039] For reference, both the first gasket 10 and the second gasket 10' are elastic rubber gaskets. Thus, when the first half-ring 51 and the second half-ring 52 are docked and the first gasket 10 and the second gasket 10' are squeezed, the rubber gaskets will deform instantaneously and make their connection tighter.
[0040] In one embodiment, the length of the first gasket 10 on the first half-ring 51 can be half of the first half-ring 51, and the length of the second gasket 10' on the second half-ring 52 can be half of the second half-ring 52. In this way, when the first half-ring 51 and the second half-ring 52 are docked, the outer wall of the first gasket 10 abuts against the end of the second half-ring 52, and the outer wall of the second gasket 10' abuts against the end of the first half-ring 51.
[0041] In another possible embodiment, the two ends of the first gasket 10 are flush with the two ends of the first half-ring 51; the two ends of the second gasket 10' are flush with the two ends of the second half-ring 52. It can be understood that the length of the first gasket 10 is the same as the length of the end of the first half-ring 51, and the length of the second gasket 10' is the same as the length of the end of the second half-ring 52.
[0042] Embodiment 5
[0043] In order to achieve quick disassembly and assembly of the connection structure 3, as Figure 4 shown, the locking member 7 includes a fixed ear 71 provided on the first half-ring 51 and a docking ear 71' provided on the second half-ring 52 that cooperates with the fixed ear 71, and the fixed ear 71 and the docking ear 71' are fixedly connected by a bolt. It can be understood that internal threads are provided on the inner walls of the fixed ear 71 and the docking ear 71', and the two are fixed by a threaded bolt. Of course, in order to further enhance the fastening of the bolt, multiple nuts can also be provided.
[0044] Embodiment 6
[0045] The utility model also relates to a fresh air pipeline system, which includes a fresh air distributor and an air inlet pipe 100; wherein, the air inlet pipe 100 is connected to the air inlet of the air distribution box 1, the air outlet pipe 4 is connected to the air outlet of the air distribution box 1, there are several air outlets, each air outlet is provided with a air distribution valve 2, and each air distribution valve 2 is provided with a connection structure 3.
[0046] As Figure 7 shown, the fresh air pipeline system includes an air inlet pipe 100 and a plurality of air outlet pipes 4. The air outlet pipes 4 can be arranged on any side of the fresh air distributor body 1, but not on the same side as the air inlet pipe 100.
[0047] The above embodiments only represent the specific implementation manners of the utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the patent scope of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the utility model.
