Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning pipeline installation, and particularly to an air-conditioning pipeline connection structure. Background Art

[0002] The connection structure of the air-conditioning pipeline is an important part to ensure the normal operation of the air-conditioning system. The fresh air pipeline in the air-conditioning system is a key component for introducing fresh air from the outside into the room, which helps to improve the indoor air quality and provide a healthier living or working environment. Common connection structures of the fresh air pipeline include: plug-in connection, clamping ring connection, etc. One end of the plug-in connection structure is the insertion part, and the other end is the receiving part. It is necessary to use sealing tape or sealing ring at the interface to ensure airtightness.

[0003] Currently, the connection of the fresh air pipeline is usually to connect the fresh air pipeline and the air outlet. In order to adapt to the on-site building conditions, an extension hose is usually used to increase the connection distance between the fresh air pipeline and the air outlet. First, the fresh air pipeline is inserted into the end of the extension hose. One end of the extension hose connected to the air outlet is usually made of silica gel. The extension hose is sleeved on the connection end of the air outlet. Finally, the pipeline is supported and fixed by means of a hanger, etc. However, for the existing plug-in connection, it is necessary to sleeve the sealing ring on the pipeline connection before connection, or wrap the sealing tape around the pipeline connection after connection, which increases the installation steps and the sealing effect needs to be improved. Secondly, in order to ensure the sealing performance of the connection between the hose pipeline and the air outlet, it is more laborious to sleeve the silica gel ring part of the hose pipeline on the air outlet, wasting operation time. Moreover, when the pipeline is fixed on the building after connection, it will shake or move, and the stability of the connection part needs to be improved. If there is a gap at the connection part, it will affect the pipeline airtightness.

[0004] Therefore, in order to improve the sealing effect and installation efficiency, the present invention provides an air-conditioning pipeline connection structure. Summary of the Invention

A rack three is fixed to the top of the outer wall of the driving ring, and a push rod installed on the left side of the wedge block two is fixedly connected to the side wall of the arc-shaped support plate.

[0013] In the above-mentioned air-conditioning duct connection structure, the sealing socket assembly includes an auxiliary socket. A plurality of first slots are formed in the left end side wall of the air outlet head along the circumferential direction, and the auxiliary socket is arranged in the first slots. The side wall of the first slot close to the auxiliary socket is provided with a special-shaped slide rail in the left-right direction, and the special-shaped slide rail is composed of two linear slide rails inclined towards the outside of the air outlet head. The ends of the two linear slide rails close to the outside of the air outlet head are connected to each other.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Refer to Figure 1 , an air-conditioning duct connection structure, including a fresh air duct 1, a connection mechanism 2 is arranged on the fresh air duct 1, an air outlet mechanism 3 is arranged on the connection mechanism 2, and the fresh air duct 1, the connection mechanism 2 and the air outlet mechanism 3 are distributed in sequence from left to right.

[0034] The fresh air duct 1 and the air outlet mechanism 3 are connected through the connection mechanism 2, and the connected fresh air duct 1, the connection mechanism 2 and the air outlet mechanism 3 are installed on an external building structure through the support mechanism 4. The support mechanism 4 supports the fresh air duct 1, the connection mechanism 2 and the air outlet mechanism 3. After installation, the support mechanism 4 further strengthens the connection between the fresh air duct 1 and the connection mechanism 2 and the seal at the connection between the connection mechanism 2 and the air outlet mechanism 3.

[0035] Refer to Figures 1 to 2 , the connection mechanism 2 includes a connection hose 21 and a sealed connection assembly 22 and a silicone sleeve ring 24 respectively arranged at the left and right ends of the connection hose 21. A driving assembly 23 is arranged on the sealed connection assembly 22, and the sealed connection assembly 22 is used to enhance the connection sealing performance between the right end of the fresh air duct 1 and the left end of the connection hose 21.

[0036] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 6 , the sealing connection assembly 22 includes an annular connector 221. The left end of the connecting hose 21 is fixedly connected to the annular connector 221. Three bumps 222 are circumferentially distributed on the side wall of the left end of the annular connector 221. A first wedge block 223 corresponding to the bump 222 is slidably connected left and right on the inner ring wall of the annular connector 221 close to the side wall of the fresh air duct 1 through a first spring (not shown in the figure). The bump 222 and the corresponding first wedge block 223 are connected by an L-shaped rod; an arc-shaped support plate 224 corresponding to the bump 222 is slidably connected radially on the inner ring wall of the annular connector 221 close to the side wall of the fresh air duct 1 through a second spring (not shown in the figure). A second wedge block 225 corresponding to the bump 222 is fixedly connected to the side of the arc-shaped support plate 224 away from the fresh air duct 1. The outer wall of the first wedge block 223 close to the fresh air duct 1 is inclined, and the side of the second wedge block 225 away from the fresh air duct 1 is inclined to match the first wedge block 223; two fixed mounting seats 226 are symmetrically fixedly connected to the left and right on the side of the arc-shaped support plate 224 close to the fresh air duct 1. A sliding mounting seat 227 is slidably connected circumferentially on the middle of the side of the arc-shaped support plate 224 close to the fresh air duct 1 through a third spring (not shown in the figure). A first sealing strip 228 can be detachably mounted on the sides of the fixed mounting seat 226 and the sliding mounting seat 227 close to the fresh air duct 1.

[0037] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 6 , the driving assembly 23 includes a sliding piece 231. An arc-shaped sliding rail corresponding to the sliding mounting seat 227 is jointly opened on the arc-shaped support plate 224 and the corresponding second wedge block 225. A sliding piece 231 slidably connected to the arc-shaped sliding rail is fixed to the side of the sliding mounting seat 227 away from the fresh air duct 1. A driving ring 232 is rotatably connected to the outer wall of the annular connector 221. A spring rod is installed between the side wall of the sliding piece 231 away from the fresh air duct 1 and the inner ring wall of the driving ring 232. A third rack is fixed to the top of the outer ring wall of the driving ring 232. A push rod 233 installed to the left of the second wedge block 225 is fixedly connected to the side wall of the arc-shaped support plate 224.

[0038] When connecting the fresh air duct 1 and the connecting hose 21, hold the end of the fresh air duct 1 and insert the fresh air duct 1 into the inside of the annular connector 221 from left to right. When the fresh air duct 1 is inserted into the inside of the annular connector 221 and pushes the bump 222, the bump 222 drives the wedge block 223 to slide to the right through the L-shaped rod. The inclined surface of the wedge block 223 pushes the inclined surface of the wedge block 225, and the wedge block 225 moves towards the fresh air duct 1. The wedge block 225 drives the arc-shaped support plate 224, the fixed mounting seat 226 and the sliding mounting seat 227 to move towards the fresh air duct 1. A plurality of protrusions are evenly distributed on the outer wall of the fresh air duct 1. The fixed mounting seat 226 and the sliding mounting seat 227 drive a plurality of sealing strips 228 to gradually approach the outer wall of the fresh air duct 1 and cooperate with the protrusions on the outer wall of the fresh air duct 1 to seal the connection. The plurality of sealing strips 228 can enhance the sealing effect, and there is no need to sleeved the sealing strip on the end of the fresh air duct 1 before installation, which simplifies the installation steps.

[0039] The initial position of the wedge block 223 is to cover part of the arc-shaped slide rail. When the wedge block 223 moves to the right, the wedge block 223 no longer covers the arc-shaped slide rail (as Figure 4 shown), avoiding blocking the movement of the sliding piece 231. The initial position of the sliding piece 231 is staggered with the wedge block 225 (as Figure 6 shown). Slightly rotate the driving ring 232 forward, and the driving assembly 23 drives the spring rod and the sliding piece 231 to displace. The sliding piece 231 rotates along the arc-shaped slide rail until it is partially staggered with the wedge block 225 and then stops moving to complete the installation. When the sliding piece 231 moves to be partially staggered with the wedge block 225, the sliding piece 231 slides on the arc-shaped support plate 224 to block the leftward movement of the wedge block 223, thereby locking the positions of the arc-shaped support plate 224, the fixed mounting seat 226, the sliding mounting seat 227 and the sealing strip 228, making the connection between the fresh air duct 1 and the connecting hose 21 more stable and preventing gaps from being generated between the fresh air duct 1 and the connecting hose 21 due to shaking, which affects the sealing performance.

[0040] After using for a certain period of time, the elasticity of the first sealing strip 228 decreases, and it is necessary to disassemble and replace the first sealing strip 228. Before disassembly and replacement, the fresh air duct 1 and the connecting mechanism 2 are disassembled and separated (since the elasticity of the first sealing strip 228 decreases, the contact tightness between it and the fresh air duct 1 is reduced, and the fresh air duct 1 can be manually pulled out from the left end of the connecting mechanism 2). Press the push rod 233 into the inside of the annular connector 221, and the push rod 233 pushes the arc-shaped support plate 224, the fixed mounting seat 226 and the sliding mounting seat 227 to move integrally towards the middle of the annular connector 221, and the spring rod expands and contracts adaptively. When the fixed mounting seat 226 and the sliding mounting seat 227 drive the first sealing strip 228 to move to a height where it can be operated from the inside of the annular connector 221 on the left side, the first sealing strip 228 is disassembled and separated from the fixed mounting seat 226 and the sliding mounting seat 227 for replacement and maintenance.

[0041] Refer to Figure 1 and Figure 8 , the air outlet mechanism 3 includes an air outlet head 31 provided on the silica gel sleeve ring 24 and a sealing socket assembly 32 provided on the air outlet head 31 for assisting the docking of the silica gel sleeve ring 24 and the air outlet head 31.

[0042] Refer to Figures 8 to 9 , the sealing socket assembly 32 includes an auxiliary socket part 322. A plurality of first slots are formed in the left end side wall of the air outlet head 31 along the circumferential direction, and the auxiliary socket part 322 is arranged in the first slots. An irregular slide rail 321 in the left-right direction is formed in the side wall of the first slot close to the auxiliary socket part 322. The irregular slide rail 321 is composed of two straight slide rails inclined towards the outside of the air outlet head 31, and the ends of the two straight slide rails close to the outside of the air outlet head 31 are connected to each other. The auxiliary socket part 322 slides left and right on the irregular slide rail 321. The auxiliary socket part 322 is composed of an arc-shaped plate slidably connected to the irregular slide rail 321 and an inclined arc plate fixed to the left side wall of the arc-shaped plate; A plurality of second sealing strips 323 are detachably installed on the side wall of the air outlet head 31 along the circumferential direction, and a plurality of second sealing strips 323 are also detachably installed on the plurality of first slots. A second slot for the corresponding second sealing strip 323 to pass through is formed in the auxiliary socket part 322.

[0043] When connecting the connecting hose 21 and the air outlet head 31, hold the silica gel sleeve ring 24 connected to the end of the connecting hose 21, and sleeved the right end of the silica gel sleeve ring 24 on the arc-shaped plate along the inclined arc plate from left to right. The initial state of the auxiliary socket part 322 is that the arc-shaped plate is slidably connected to the leftmost end of the irregular slide rail 321. At this time, the diameter of the circle formed by a plurality of auxiliary socket parts 322 is smaller than the diameter of the left end of the air outlet head 31, so as to easily sleeve the silica gel sleeve ring 24.

[0044] Push the limelight 31 to the left. The limelight 31 drives the special-shaped slide rail 321 to slide relative to the auxiliary socket 322 and the silicone sleeve ring 24. The auxiliary socket 322 slides along the special-shaped slide rail 321. The two linear slide rails are of different lengths. The auxiliary socket 322 first moves along the long slide rail. Multiple auxiliary sockets 322 gradually expand and move outwards, driving the sleeved silicone sleeve ring 24 to expand. The expanded silicone sleeve ring 24 gradually moves relative to the outside of the left end of the limelight 31. When the silicone sleeve ring 24 expands to the maximum range, the auxiliary socket 322 moves to the intersection of the long slide rail and the short slide rail. The auxiliary socket 322 continues to move into the short slide rail. Multiple auxiliary sockets 322 moving on the short slide rail quickly move inwards and close to each other, causing the silicone sleeve ring 24 to retract and reset until the second sealing strip 323 enters the corresponding slot two in the second sealing strip 323. At this time, the diameter of the circle formed by multiple arc-shaped plates is equal to the diameter of the left end of the limelight 31. At this time, the silicone sleeve ring 24 tightly sleeves the outer walls of the limelight 31 and the arc-shaped plates, and the second sealing strip 323 is in close contact with the inner wall of the silicone sleeve ring 24, completing the connection between the silicone sleeve ring 24 and the limelight 31.

[0045] Refer to Figure 1 、 Figure 2 and Figure 5 As shown in FIGS.

[0046] Refer to Figure 2 and Figure 5 The left support assembly 41 includes a left docking seat 411. The left docking seat 411 is installed on the annular connection head 221. The left docking seat 411 is composed of a first circular ring piece sleeved on the outer wall of the annular connection head 221 and a first connection seat fixed to the top wall of the first circular ring piece. The bottom wall of the first connection seat is slidably connected to a first rack 412 through a fourth spring (not shown in the figure). The first rack 412 meshes with the third rack.

[0047] Refer to Figure 2 、 Figure 7 and Figure 9, the right support assembly 42 includes a right docking seat 421. The right docking seat 421 is installed on the silicone sleeve ring 24. The right docking seat 421 is composed of a second circular ring piece sleeved on the outer wall of the silicone sleeve ring 24 and two second connecting seats fixedly distributed up and down on the side wall of the second circular ring piece. The bottom wall of the upper second connecting seat is slidably connected back and forth by a fifth spring (not shown in the figure) with a second rack 422. The top wall of the lower second connecting seat is provided with a clamping hoop 423. The clamping hoop 423 is composed of two semi-circular ring pieces and a fourth rack connecting the two semi-circular ring pieces and meshing with the second rack 422. One of the two semi-circular ring pieces is relatively fixedly installed on the lower second connecting seat, and the other semi-circular ring piece is hinged to the lower second connecting seat. One end of the fourth rack is fixed to the top end of the hinged semi-circular ring piece, and the other end of the fourth rack is slidably connected to the top end of the fixed semi-circular ring piece. A third sealing strip 424 is detachably installed on the inner wall of the clamping hoop 423.

[0048] Referring to Figure 2 , Figure 5 and Figure 7 , the installation assembly 43 includes a support seat 431. The support seat 431 is snap-fitted front and back on both the first connecting seat and the upper second connecting seat. A plurality of bolts 432 are rotatably connected to the middle of the support seat 431. A stop strip 433 is fixedly connected to the bottom wall of the support seat 431 and is arranged behind the first rack 412 and the second rack 422.

[0049] After the fresh air duct 1, the connecting mechanism 2 and the air outlet mechanism 3 form an integral body, first fix the support seat 431 to a suitable building structure through the bolts 432.

[0050] When connecting the left support assembly 41 and the installation assembly 43, align the left docking seat 411 with the corresponding support seat 431 and push it backward to approach the support seat 431 until the first connecting seat is snap-fitted with the support seat 431. During the process of the left docking seat 411 being snap-fitted with the support seat 431, the first rack 412 gradually approaches the stop strip 433 and slides forward relative to the stop strip 433. The first rack 412 and the third rack cooperate to drive the driving ring 232 to rotate. The rotation of the driving ring 232 drives the sliding piece 231, the sliding mounting seat 227 and the corresponding first sealing strip 228 to rotate. The initial position of the first sealing strip 228 corresponding to the sliding mounting seat 227 is in a state close to overlapping with the first sealing strip 228 corresponding to the fixed mounting seat 226, and after rotation, it changes to a state staggered with the first sealing strip 228 corresponding to the fixed mounting seat 226 (as Figure 6 shown), and the first sealing strip 228 corresponding to the fixed mounting seat 226 and the first sealing strip 228 corresponding to the sliding mounting seat 227 are staggered, which is beneficial to reducing the sealing dead angle and enhancing the sealing performance.

[0051] When the right support component 42 and the mounting component 43 are connected, align the right docking seat 421 with the corresponding support seat 431 and push it backward to approach the support seat 431 until the upper connecting seat two is snap-connected to the support seat 431. During the process of the snap connection between the right docking seat 421 and the support seat 431, the second rack 422 gradually approaches the stop bar 433 and slides forward relative to the stop bar 433. The second rack 422 cooperates with the fourth rack, and the fourth rack drives the movable half-ring member to rotate and approach the fixed half-ring member. The sealing strip three 424 on the half-ring member wraps the silicone sleeve ring 24 from the outside. The sealing strip three 424 cooperates with the second sealing strip 323 to enhance the sealing performance of the connection between the air outlet head 31 and the silicone sleeve ring 24 from both inside and outside directions.

[0052] Refer to Figures 1 - 9 , the specific operation steps of the air-conditioning duct connection structure are as follows: When the fresh air duct 1 and the connecting hose 21 are connected, hold the end of the fresh air duct 1 and insert it into the inside of the annular connecting head 221 from left to right, push the convex block 222, and the first wedge block 223 and the second wedge block 225 cooperate.
