Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment connection technology, specifically a quick-connect device for an air supply pipe for an electric motor. Background Technology

[0002] In modern industrial production, commercial buildings, and various public facilities, electric fans are core equipment in ventilation, heat dissipation, and air conditioning systems. Their stable operation is crucial to ensuring environmental comfort and production efficiency. As the air supply duct serves as the airflow transport channel between the electric fan and the target space, the quality of its connection with the electric fan directly affects the performance of the entire ventilation system.

[0003] Currently, the connection between traditional electric fans and air supply pipes mostly relies on a combination of flanges and bolts. This requires workers to precisely align the flange of the air supply pipe with the corresponding flange of the electric fan's exhaust pipe. Then, bolts need to be inserted one by one and tightened with tools. Since there are many bolts, and the tightening process needs to ensure that the tightness of each bolt is uniform to avoid affecting the sealing effect, the entire operation process is extremely cumbersome and time-consuming. Therefore, we need to propose a quick connection device for electric motor air supply pipes. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3 This utility model provides a quick docking device for an electric motor's air supply pipe, comprising: an electric fan 1, with an exhaust pipe 2 at its exhaust end; an air supply pipe 3 connected to one end of the exhaust pipe 2; a docking mechanism 4, which allows the air supply pipe 3 to be installed at one end of the exhaust pipe 2; the docking mechanism 4 includes a first connecting plate 41, a second connecting plate 42, four sets of locking blocks 43, and a locking ring 44. The first connecting plate 41 is welded to the outer wall of one end of the exhaust pipe 2, the second connecting plate 42 is welded to the outer wall of one end of the air supply pipe 3, the four sets of locking blocks 43 are welded in a ring array to one side of the second connecting plate 42, and one end of each of the four sets of locking blocks 43 passes through the first connecting plate 41 and is threadedly connected to the locking ring 44; and a clamping mechanism 5, which is disposed on the outer walls of the first connecting plate 41 and the second connecting plate 42 to strengthen the connection between the exhaust pipe 2 and the air supply pipe 3.

[0026] In this embodiment, the first connecting plate 41 and the second connecting plate 42 are connected, and then four sets of locking blocks 43 are made to pass through the first connecting plate 41. The locking ring 44 is tightened on the four sets of locking blocks 43, and then the clamping mechanism 5 is clamped on the outer wall of the first connecting plate 41 and the second connecting plate 42. This completes the connection between the exhaust pipe 2 and the air supply pipe 3. The whole process is relatively simple and saves connection time.

[0027] The first connecting plate 41 has four sets of through slots 45 that are adapted to the locking blocks 43. The four sets of locking blocks 43 pass through the four sets of through slots 45 and are located at one end of the first connecting plate 41.

[0028] In this embodiment, when the first connecting plate 41 and the second connecting plate 42 are docked and fit together, the four sets of locking blocks 43 will pass through the four sets of through slots 45. The four sets of through slots 45 can limit the four sets of locking blocks 43, thereby limiting the first connecting plate 41 and the second connecting plate 42, and can also play a guiding role, making it easier for the first connecting plate 41 and the second connecting plate 42 to align.

[0029] Each of the four sets of locking blocks 43 has threads that are compatible with the locking ring 44. The locking ring 44 is threaded onto the four sets of locking blocks 43, and three sets of grip rods 46 are fixedly connected to the outer wall of the locking ring 44 in a ring array.

[0030] In this embodiment, after the four sets of locking blocks 43 pass through the four sets of through slots 45, part of the four sets of locking blocks 43 will be located at one end of the first connecting plate 41. At this time, the locking ring 44 can be tightened onto the four sets of locking blocks 43 by holding the handle 46 and rotating it in the reverse direction.

[0031] Both the first connecting plate 41 and the second connecting plate 42 have grooves 6 at their opposite ends, and a sealing ring 7 is provided inside the grooves 6.

[0032] In this embodiment, when installing the air supply pipe 3, the sealing ring 7 is first placed inside the groove, and then the first connecting plate 41 and the second connecting plate 42 are connected. Under the action of force, one end of the sealing ring 7 will be squeezed into the inside of another set of grooves, and the sealing ring 7 will be continuously squeezed to improve the sealing effect.

[0033] The clamping mechanism 5 includes an upper clamp 51, a lower clamp 52, and a clamping assembly 53. One end of the upper clamp 51 is rotatably connected to the lower clamp 52. Sealing gaskets 54 are provided on the inner walls of both the upper clamp 51 and the lower clamp 52. The upper clamp 51 and the lower clamp 52 are engaged on the outer walls of the first connecting plate 41 and the second connecting plate 42.

[0034] In this embodiment, the upper clamp 51 and the lower clamp 52 are used in a ring shape, clamping the upper clamp 51 and the lower clamp 52 onto the outer walls of the first connecting plate 41 and the second connecting plate 42, so that the sealing gasket 54 is in contact with the first connecting plate 41 and the second connecting plate 42. When the clamping component 53 is used, the sealing gasket 54 is squeezed, so that the sealing gasket 54 is firmly attached to the outer walls of the first connecting plate 41 and the second connecting plate 42. It is worth noting that the first connecting plate 41 and the second connecting plate 42 are provided with mounting grooves, which facilitates the limiting installation of the clamp mechanism 5.

[0035] The snap-fit ​​assembly 53 includes a housing 531, a snap-fit ​​connector 532, a spring 533, a pull rod 534, two sets of limit blocks 535, and a snap-fit ​​block 536. The housing 531 is fixedly connected to the outer wall of the lower clamp 52. The snap-fit ​​connector 532 is slidably installed inside the housing 531. One end of the pull rod 534 is fixedly connected to the snap-fit ​​connector 532, and one end of the pull rod 534 passes through the housing 531 and is located on one side of the housing 531. The spring 533 is sleeved on the outer wall of the pull rod 534. The snap-fit ​​block 536 is fixedly connected to the outer wall of the upper clamp 51, and the bottom of the snap-fit ​​block 536 passes through the housing 531 and snaps into the snap-fit ​​connector 532.

[0036] In this embodiment, the snap-fit ​​block 536 is moved into the interior of the housing 531. After entering the interior of the housing 531, the snap-fit ​​block 536 will contact the snap-fit ​​connector 532. Since the top of the snap-fit ​​connector 532 is inclined, the snap-fit ​​connector 532 will move under the action of force, causing the spring 533 to contract. When the snap-fit ​​block 536 moves to a certain position, since the snap-fit ​​block 536 has a snap-fit ​​groove that matches the snap-fit ​​connector 532, under the action of the spring's rebound force, the snap-fit ​​connector 532 will be pushed to move, and the snap-fit ​​connector 532 will snap into the interior of the snap-fit ​​groove, fixing the snap-fit ​​block 536. At this time, the installation of the clamp mechanism 5 can be completed.

[0037] When it is necessary to remove the clamp mechanism 5, simply pull the lever 534. The lever 534 will move the clamp connector 532 away from the clamp block 536, thus removing the fixation of the clamp block 536. At this time, the clamp mechanism 5 can be removed.

[0038] Two sets of limiting grooves are provided on the inner wall of the housing 531. Two sets of limiting blocks 535 are slidably installed inside the two sets of limiting grooves, and the two sets of limiting blocks 535 are fixedly connected to both sides of the snap connector 532.

[0039] In this embodiment, when the snap-fit ​​connector 532 moves, it will drive the two sets of limiting blocks 535 to move inside the two sets of limiting grooves. The two sets of limiting blocks 535 can support the snap-fit ​​connector 532 and ensure that the snap-fit ​​connector 532 moves in a straight line, thereby improving its stability.

[0040] Working principle: When using this utility model, first place the sealing ring 7 inside the groove, then connect the first connecting plate 41 and the second connecting plate 42, so that the four sets of locking blocks 43 pass through the first connecting plate 41, and tighten the locking ring 44 on the four sets of locking blocks 43. Under the action of force, one end of the sealing ring 7 will be squeezed into the inside of another set of grooves, and the sealing ring 7 will be continuously squeezed to improve the sealing effect. Then, the clamp mechanism 5 is clamped on the outer wall of the first connecting plate 41 and the second connecting plate 42, thus completing the connection between the exhaust pipe 2 and the air supply pipe 3. The whole process is relatively simple and saves connection time.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
