DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Reference Figures 1 to 9 As shown, the embodiment of the utility model provides a central air conditioning ventilation system installation structure, including a first pipe 1 and a second pipe 2, the opening edges of the first pipe 1 and the second pipe 2 are respectively formed with a first flange 11 and a second flange 21, and the first flange 11 and the second flange 21 are correspondingly provided with a plurality of installation holes 111, and the first pipe 1 and the second pipe 2 are assembled together through a connector 3;

[0030] The connector 3 comprises: an inner cushion layer 31, the cross-sectional size of the inner cushion layer 31 is adapted to the cross-sectional size of the first flange 11 and the second flange 21, and the inner cushion layer 31 is located between the first flange 11 and the second flange 21, and a plurality of first positioning columns 32 and a second positioning column 33 are respectively provided at both ends of the inner cushion layer 31; the plurality of first positioning columns 32 and the second positioning columns 33 correspond to each other one by one and are respectively inserted into the mounting holes 111 on the first flange 11 and the second flange 21, so as to realize the radial limitation of the first pipe 1 and the second pipe 2;

[0031] There are a plurality of locking members 4 , each first positioning column 32 and second positioning column 33 corresponds to a locking member 4 , and each group of relative first positioning columns 32 and second positioning columns 33 are locked by two locking members 4 to achieve axial limitation of the first pipe 1 and the second pipe 2 .

[0032] In this embodiment, when assembling the first pipe 1 and the second pipe 2, firstly, the inner cushion layer 31 is aligned with the first flange 11 on the first pipe 1, and the multiple first positioning columns 32 are aligned with the mounting holes 111 on the first flange 11 to achieve preliminary positioning of the inner cushion layer 31. Then, the second pipe 2 is aligned with the first pipe 1, and the multiple mounting holes 111 on the second flange 21 are aligned with the multiple second positioning columns 33 to achieve radial limitation between the first pipe 1 and the second pipe 2. Then, locking members 4 are installed one by one on the multiple first positioning columns 32 and the multiple second positioning columns 33. After the locking members 4 are locked on the corresponding positioning columns, it can be ensured that the first flange 11 and the second flange 21 are both in contact with the inner cushion layer 31 and locked. In summary, the assembly between the two pipes can be quickly achieved, the workload of the staff is reduced, and the assembly efficiency of the staff is improved.

[0033] Specifically, the locking member 4 includes an outer ring portion 41, an inner ring portion 42 and at least one plug-in portion 43. In this embodiment, two plug-in portions 43 are provided. The outer ring portion 41 is fixedly sleeved on the inner ring portion 42; the plug-in portion 43 is radially slidable along the inner ring portion 42 in a slot 421 on the inner ring portion 42, a stopper 431 is provided on the top of the plug-in portion 43, and the stopper 431 is slidably provided in a limiting groove 411 on the outer ring block, and a spring 44 is installed in the limiting groove 411 and elastically resists the stopper 431;

[0034] The inner annular portion 42 slides onto the first positioning column 32, the plug-in portion 43 shrinks into the limiting groove 411, and the end of the plug-in portion 43 contacts the peripheral wall of the first positioning column 32, and the spring 44 shrinks. When the plug-in portion 43 slides to the slot 321, the spring 44 allows the plug-in portion 43 to be inserted into the slot 321 on the outer wall of the first positioning column 32, thereby realizing the axial locking of the first flange 11 and the first positioning column 32. The width of the plug-in portion 43 matches the width of the slot 321. At this time, the first flange 11 is tightly attached to the inner cushion layer 31. Similarly, another connecting portion can be installed on the second positioning column 33 by the same method, thereby realizing the assembly between the two pipes.

[0035] In addition, the inner annular block and the outer annular block can be fixedly connected by bolts, and the function of the stop block 431 is to limit the moving stroke of the plug-in part 43, so that when the plug-in part 43 or the spring 44 is assembled or the plug-in part 43 is damaged and needs to be replaced, the inner annular block can be removed, thereby facilitating maintenance and assembly.

[0036] Specifically, one side end of the slot 321 extends along the circumference of the first positioning column 32 and gradually and smoothly transitions to the circumference of the first positioning column 32;

[0037] In this embodiment, the slot 321 is extended by such a specific shape, so when the two pipes need to be disassembled, the inner annular portion 42 needs to be rotated along the extension direction of the slot 321, and the plug-in portion 43 can be gradually retracted into the limiting groove 411 under the squeezing effect of the bottom of the slot 321 on the plug-in portion 43, so that the plug-in portion 43 is completely separated from the slot 321, so that the connecting member 3 can be removed from the corresponding first positioning column 32 or the second positioning column 33, and the operation is convenient.

[0038] Specifically, a chamfered surface 322 is provided at the outer end of the first positioning post 32 to facilitate the inner annular block to slide onto the first positioning post 32 .

[0039] Specifically, a first rounded corner 432 is provided at the bottom of one side end of the plug-in portion 43; when the inner annular portion 42 slides into the first positioning column 32, the first rounded corner 432 first contacts the chamfered surface 322 of the first positioning column 32, so that the plug-in portion 43 can slide into the peripheral wall of the first positioning column 32 along the chamfered surface 322 through the first rounded corner 432.

[0040] Specifically, a guide groove 323 extending along its axial direction is provided on the outer wall of the first positioning column 32, and the guide groove 323 is adapted to the bottom shape of the plug-in portion 43; the plug-in portion 43 slides into the guide groove 323 through the chamfered surface 322 of the first positioning column 32, and is inserted into the card slot 321 through the end of the guide groove 323, so that the main function of the guide groove 323 is to guide the card connector, ensuring that the plug-in portion 43 of the connector 3 can slide in the direction of the card slot 321 at a position facing the card slot 321.

[0041] In summary, the installation method of the connecting member 3 and the second positioning column 33 is consistent with the installation method of the first positioning column 32, thereby achieving the connection between the two pipes.

[0042] Specifically, both ends of the inner cushion layer 31 are provided with installation grooves 311 extending along the contour thereof, and a sealing gasket 312 is installed in each installation groove 311. The sealing gasket 312 enables the first flange 11 and the second flange 21 to be firmly in contact with the sealing gasket 312 when the first pipe 1 and the second pipe 2 are connected, thereby avoiding a gap between the first flange 11 and the second flange 21 and the inner cushion layer 31, which would affect the sealing between the first pipe 1 and the second pipe 2.

[0043] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
