Description

Technical Field

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

[0002] The connection structure of air-conditioning ducts is an important part to ensure the normal operation of the air-conditioning system. The fresh air duct 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 fresh air ducts include: plug-in connection, clamping ring connection, etc. The plug-in connection structure has an insertion part at one end and a receiving part at the other end. Sealing tape or a sealing ring is required at the interface to ensure airtightness.

[0003] At present, the connection of fresh air ducts is usually to connect the fresh air duct and the air outlet. In order to adapt to the on-site construction conditions, an extension hose is usually used to increase the connection distance between the fresh air duct and the air outlet. The fresh air duct is first plugged into the end of the extension hose. The end of the extension hose connected to the air outlet is usually made of silicone. The extension hose is sleeved on the connection end of the air outlet, and finally the duct is supported and fixed by a hanger or the like. However, the existing plug-in connection requires a sealing ring to be sleeved on the duct connection before connection, or a sealing tape to be wrapped around the duct connection after connection, which increases the installation steps and the sealing effect needs to be improved. Secondly, in order to ensure the sealing of the connection between the hose duct and the air outlet, the silicone ring part of the hose duct is more laborious when sleeved on the air outlet, which wastes working time. Furthermore, when the duct is fixed on the building after connection, it will shake or move, and the stability of the connection needs to be improved. If a gap is generated at the connection, it will affect the sealing of the duct.

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

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 An air conditioning duct connection structure includes a fresh air duct 1, a connecting mechanism 2 is provided on the fresh air duct 1, and an air outlet mechanism 3 is provided on the connecting mechanism 2. The fresh air duct 1, the connecting 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 by a connecting mechanism 2, and the fresh air duct 1, the connecting mechanism 2 and the air outlet mechanism 3 connected into a whole are installed on the external building structure through the supporting mechanism 4. The supporting mechanism 4 supports the fresh air duct 1, the connecting mechanism 2 and the air outlet mechanism 3. After the installation is completed, the supporting mechanism 4 further strengthens the connection between the fresh air duct 1 and the connecting mechanism 2, and the sealing of the connection between the connecting mechanism 2 and the air outlet mechanism 3.

[0035] Reference Figures 1 to 2 The connecting mechanism 2 includes a connecting hose 21 and a sealing connecting component 22 and a silicone ring 24 respectively provided at the left and right ends of the connecting hose 21. A driving component 23 is provided on the sealing connecting component 22. The sealing connecting component 22 is used to enhance the connection sealing between the right end of the fresh air duct 1 and the left end of the connecting hose 21.

[0036] Reference 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 protrusions 222 are distributed circumferentially on the side wall of the left end of the annular connector 221. The inner ring wall of the annular connector 221 close to the side wall of the fresh air duct 1 is connected to a wedge 223 corresponding to the protrusion 222 by a spring 1 (not shown in the figure). The protrusion 222 and the corresponding wedge 223 are connected by an L-shaped rod; the inner ring wall of the annular connector 221 close to the side wall of the fresh air duct 1 is radially slidably connected to an arc-shaped support plate 224 corresponding to the protrusion 222 by a spring 2 (not shown in the figure). The side of the support plate 224 away from the fresh air duct 1 is fixedly connected to a wedge block 225 corresponding to the wedge block 1 223, the outer wall of the wedge block 1 223 close to the fresh air duct 1 is inclined, and the side of the wedge block 225 away from the fresh air duct 1 is inclined to match the wedge block 1 223; the side of the arc-shaped support plate 224 close to the fresh air duct 1 is symmetrically fixedly connected to a fixed mounting seat 226, and the middle part of the side of the arc-shaped support plate 224 close to the fresh air duct 1 is circumferentially slidably connected to a sliding mounting seat 227 through a spring three (not shown in the figure), and the fixed mounting seat 226 and the sliding mounting seat 227 close to the fresh air duct 1 can be removably installed with a sealing strip 1 228.

[0037] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 6 The driving assembly 23 includes a sliding piece 231, and the arc-shaped support plate 224 and the corresponding wedge block 225 are jointly provided with an arc-shaped slide rail corresponding to the sliding mounting seat 227. The sliding mounting seat 227 is fixed with a sliding piece 231 slidably connected to the arc-shaped slide rail on the side away from the fresh air duct 1. The outer wall of the annular connector 221 is rotatably connected to the driving ring 232. 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 rack three is fixed to the top of the outer ring wall of the driving ring 232. The side wall of the arc-shaped support plate 224 is fixedly connected to a push rod 233 installed on the left side of the wedge block 225.

[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 from left to right into the annular connector 221. When the fresh air duct 1 is inserted into the annular connector 221 and pushes the protrusion 222, the protrusion 222 pulls the wedge 1 223 to slide to the right through the L-shaped rod. The inclined surface of the wedge 1 223 pushes the inclined surface of the wedge 225. The wedge 225 moves toward the direction of the fresh air duct 1, and the wedge 225 drives the arc support plate 22 4. The fixed mounting seat 226 and the sliding mounting seat 227 move toward the direction of the fresh air duct 1. There are several protrusions evenly distributed on the outer wall of the fresh air duct 1. The fixed mounting seat 226 and the sliding mounting seat 227 drive multiple 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. Multiple sealing strips 228 can enhance the sealing effect. There is no need to put sealing strips 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 (eg Figure 4 As shown), to avoid blocking the movement of the sliding piece 231, the initial position of the sliding piece 231 is staggered with the wedge block 225 (as shown Figure 6 As shown in the figure), the driving ring 232 is rotated forward slightly, and the driving assembly 23 drives the spring rod and the sliding piece 231 to move. The sliding piece 231 rotates along the arc slide rail until it is partially intertwined with the wedge block 225 and stops moving, completing the installation. When the sliding piece 231 moves to partially intertwine with the wedge block 225, the sliding piece 231 slides on the arc support plate 224 to block the leftward movement of the wedge block 1 223, and then locks the positions of the arc support plate 224, the fixed mounting seat 226, the sliding mounting seat 227 and the sealing strip 1 228, making the connection between the fresh air duct 1 and the connecting hose 21 more stable, and preventing the fresh air duct 1 and the connecting hose 21 from having a gap due to shaking, thereby affecting the sealing.

[0040] After a certain period of use, the elasticity of the sealing strip 228 decreases, and the sealing strip 228 needs to be disassembled and replaced. Before replacement, the fresh air duct 1 and the connecting mechanism 2 should be disassembled and separated (due to the decrease in the elasticity of the sealing strip 228, the contact tightness between the sealing strip 228 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), and the push rod 233 is pressed toward the inside of the annular connector 221. The push rod 233 pushes the arc-shaped support plate 224, the fixed mounting seat 226 and the sliding mounting seat 227 to move toward the middle of the annular connector 221 as a whole, and the spring rod is adaptively extended and retracted. When the fixed mounting seat 226 and the sliding mounting seat 227 drive the sealing strip 228 to move to a height that can be operated from the left side of the annular connector 221, the sealing strip 228 is disassembled and separated from the fixed mounting seat 226 and the sliding mounting seat 227 for replacement and maintenance.

[0041] Reference Figure 1 and Figure 8 The air outlet mechanism 3 includes an air outlet head 31 provided on the silicone sleeve ring 24 and a sealing sleeve assembly 32 provided on the air outlet head 31 for assisting the silicone sleeve ring 24 to connect with the air outlet head 31 .

[0042] Reference Figures 8 and 9 The cam 322 is provided with a plurality of slots 323 on the left side of the cam 324, and a plurality of slots 323 are provided on the cam 324 to prevent the cam 324 from sliding out of the cam 324.

[0043] When connecting the connecting hose 21 and the air outlet 31, hold the silicone sleeve 24 connected to the end of the connecting hose 21, and sleeve the right end of the silicone sleeve 24 onto the curved plate from left to right along the inclined curved plate. The initial state of the auxiliary sleeve 322 is that the curved plate is slidably connected to the leftmost end of the special-shaped slide rail 321. At this time, the diameter of the circle surrounded by multiple auxiliary sleeves 322 is smaller than the diameter of the left end of the air outlet 31, so that the silicone sleeve 24 can be easily sleeved.

[0044] Push the air outlet head 31 to the left, and the air outlet head 31 drives the special-shaped slide rail 321 to slide relative to the auxiliary sleeve 322 and the silicone sleeve 24. The auxiliary sleeve 322 slides along the special-shaped slide rail 321. The two linear slide rails are one long and one short. The auxiliary sleeve 322 moves along the long slide rail first, and the multiple auxiliary sleeves 322 gradually expand and move outward, driving the sleeved silicone sleeve 24 to expand. The expanded silicone sleeve 24 gradually moves relative to the left end of the air outlet head 31. When the silicone sleeve 24 expands to the maximum range, the auxiliary sleeve 322 moves to the long slide rail and At the intersection of the short slide rails, the auxiliary sleeve 322 continues to move into the short slide rail, and the multiple auxiliary sleeves 322 moving on the short slide rail quickly approach inward, causing the silicone sleeve 24 to retract and reset until the sealing strip 2 323 enters the corresponding slot 2 in the sealing strip 2 323. At this time, the diameter of the circle surrounded by the multiple arc plates is equal to the diameter of the left end of the air outlet 31. At this time, the silicone sleeve 24 is tightly fitted on the outer wall of the air outlet 31 and the arc plate, and the sealing strip 2 323 is tightly attached to the inner wall of the silicone sleeve 24, completing the connection between the silicone sleeve 24 and the air outlet 31.

[0045] Reference Figure 1 、 Figure 2 and Figure 5 A support mechanism 4 is provided on both the sealing connection component 22 and the silicone ring 24. The support mechanism 4 includes a left support component 41 provided on the sealing connection component 22, a right support component 42 provided on the silicone ring 24, and an installation component 43 provided on the left support component 41 and the right support component 42.

[0046] Reference Figure 2 and Figure 5 The left support assembly 41 includes a left docking seat 411, which is installed on the annular connector 221. The left docking seat 411 is composed of a circular ring member 1 installed on the outer wall of the annular connector 221 and a connecting seat 1 fixed on the top wall of the circular ring member 1. The bottom wall of the connecting seat 1 is connected to a rack 1 412 for sliding back and forth through a spring 4 (not shown in the figure), and the rack 1 412 is engaged with the rack 3.

[0047] Reference Figure 2 、 Figure 7 and Figure 9The right support assembly 42 includes a right docking seat 421, and the right docking seat 421 is installed on the silicone sleeve 24. The right docking seat 421 consists of a circular ring part 2 that is sleeved on the outer wall of the silicone sleeve 24 and two connecting seats 2 that are fixed on the upper and lower side walls of the circular ring part 2. The bottom wall of the upper connecting seat 2 is connected to a rack 2 422 for sliding back and forth through a spring 5 (not shown in the figure), and the top wall of the lower connecting seat 2 is provided with a clamping hoop 423. The clamping hoop 423 consists of two semi-ring parts and a rack four that connects the two semi-ring parts and engages with the rack 2 422. One of the two semi-ring parts is relatively fixedly installed on the connecting seat 2 on the lower side, and the other semi-ring part is hinged to the connecting seat 2 on the lower side. One end of the rack four is fixed to the top end of the hinged semi-ring part, and the other end of the rack four is slidably connected to the top end of the fixed semi-ring part. The inner wall of the clamping hoop 423 is detachably installed with a sealing strip three 424.

[0048] Reference Figure 2 、 Figure 5 and Figure 7 The mounting assembly 43 includes a support seat 431. The connecting seat 1 and the upper connecting seat 2 are both connected with the support seat 431 in front and back engagement. The middle part of the support seat 431 is rotatably connected with a plurality of bolts 432. The bottom wall of the support seat 431 is fixedly connected with a blocking bar 433 arranged on the rear side of the rack 1 412 and the rack 2 422.

[0049] After the fresh air duct 1 , the connecting mechanism 2 and the air outlet mechanism 3 are formed into a whole, the support base 431 is first fixed to a suitable building structure by means of bolts 432 .

[0050] When the left support assembly 41 and the mounting assembly 43 are connected, the left docking seat 411 is aligned with the corresponding support seat 431 and pushed backward close to the support seat 431 until the connecting seat 1 is engaged with the support seat 431. During the process of the left docking seat 411 and the support seat 431 being engaged and connected, the rack 1 412 gradually approaches the stop bar 433 and slides forward relative to the stop bar 433. The rack 1 412 cooperates with the rack 3 to drive the driving ring 232 to rotate. The driving ring 232 rotates to drive the sliding piece 231, the sliding mounting seat 227 and the corresponding sealing strip 1 228 to rotate. The initial position of the sealing strip 1 228 corresponding to the sliding mounting seat 227 is a state of being nearly overlapped with the sealing strip 1 228 corresponding to the fixed mounting seat 226. After rotation, it changes to a state of being staggered with the sealing strip 1 228 corresponding to the fixed mounting seat 226 (such as Figure 6 As shown), the sealing strip 228 corresponding to the fixed mounting seat 226 and the sealing strip 228 corresponding to the sliding mounting seat 227 are staggered, which is beneficial to reducing sealing dead angles and enhancing sealing performance.

[0051] When the right support assembly 42 and the installation assembly 43 are connected, the right docking seat 421 is aligned with the corresponding support seat 431 and pushed backward close to the support seat 431 until the upper connecting seat 2 is engaged with the support seat 431. In the process of the right docking seat 421 and the support seat 431 being engaged and connected, the rack 2 422 gradually approaches the baffle 433 and slides forward relative to the baffle 433. The rack 2 422 cooperates with the rack 4, and the rack 4 drives the movable semi-ring part to rotate close to the fixed semi-ring part. The sealing strip 3 424 on the semi-ring part wraps the silicone sleeve 24 from the outside. The sealing strip 3 424 cooperates with the sealing strip 2 323 to enhance the sealing of the connection between the air outlet 31 and the silicone sleeve 24 from both inside and outside directions.

[0052] Reference Figures 1-9 The specific operating steps of this air-conditioning duct connection structure are as follows: when connecting the fresh air duct 1 and the connecting hose 21, hold the end of the fresh air duct 1 and insert it from left to right into the annular connector 221, push the protrusion 222, and the wedge block 1 223 and the wedge block 225 cooperate. The fixed mounting seat 226 and the sliding mounting seat 227 drive multiple sealing strips 1 228 to seal the connection. Slightly rotate the driving ring 232 forward, and the sliding piece 231 locks the position of the arc-shaped support plate 224 and the sealing strip 1 228, making the connection between the fresh air duct 1 and the connecting hose 21 more stable.
