Description

Technical Field

[0001] This utility model relates to the field of air conditioning installation technology, and more specifically, to an air conditioning hole mounting component for installing air conditioning pipes. Background Technology

[0002] During building construction, openings are typically pre-drilled in walls at appropriate locations for air conditioning ducts; these are called air conditioning holes. During air conditioning installation, the indoor and outdoor unit connecting pipes must pass through these openings and be secured and sealed. To facilitate pipe passage and protect the pipes, existing technologies often use air conditioning hole installation fittings (also known as through-wall sleeves or conduits) to line the openings.

[0003] For example, the "Air Conditioning Pipe Installation Part for Air Conditioning Hole" disclosed in Chinese Utility Model Patent (Publication No.: CN223105507U) describes a device where an outer cylinder and an inner cylinder pass through an air conditioning hole, and a second limiting ring is aligned with one side of the wall. The slider and sliding opening cooperate to adjust the length between the outer and inner cylinders according to the length of the air conditioning hole. Then, four locking blocks on the first limiting ring are inserted into four L-shaped grooves. The first limiting ring is slid towards the outer cylinder until the locking blocks are aligned with the groove wall of the L-shaped groove. Finally, the first limiting ring is rotated so that the locking blocks slide into the transverse groove of the L-shaped groove, thereby fixing the first limiting ring to the inner cylinder and also fixing the device inside the air conditioning hole. The overall structure is simple and easy to operate. Regarding the aforementioned technologies, this device has several shortcomings. In actual use, the bidirectional threaded rod clamping plate structure on the outer side of the first and second limiting rings can only be adjusted after the mounting component is fixed to the air conditioning hole. However, air conditioning holes are often located in narrow spaces near walls or at high locations, severely limiting the operating space. Furthermore, this exposed clamping plate structure easily leads to hand scraping against the wall during operation, posing a risk of falls and hand injuries, resulting in extremely poor safety. Simultaneously, the bidirectional threaded rod itself has poor self-locking performance and is prone to loosening under the vibration of the air conditioner during operation, leading to a decrease in clamping force and failing to provide a durable and stable fixation for the air conditioning pipe.

[0004] Therefore, we have made improvements and proposed an air conditioning hole mounting component for air conditioning pipe installation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an air conditioning hole mounting component for air conditioning pipe installation, which solves the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An air conditioning hole mounting component for air conditioning pipe installation includes an outer cylinder, an inner cylinder that is slidably mounted inside the outer cylinder, an outer limiting ring that is fixedly mounted on the outer wall of one end of the outer cylinder, a track that is fixedly embedded in the upper side of the inner wall of the inner cylinder, a bidirectional screw that is rotatably mounted inside the track, and symmetrically distributed adjusting blocks that are sleeved on the outer wall of the bidirectional screw, the adjusting blocks being slidably mounted on the track. An arc-shaped clamping plate is provided at the top inside the inner cylinder. Symmetrically distributed connecting rods are hinged to the upper side of the outer surface of the arc-shaped clamping plate. One end of the connecting rod is hinged to the bottom of the corresponding position adjustment block. A drive box is fixedly installed at one end of the inner cylinder. An adjustment component is provided inside the drive box.

[0007] As a preferred technical solution of this application, the adjustment component includes a worm gear rotatably installed inside the drive box. One end of the bidirectional lead screw passes through the inner cylinder and extends into the interior of the drive box. A worm wheel is fixedly installed at one end of the bidirectional lead screw. The worm gear meshes with the worm wheel. The bottom end of the worm gear passes through the drive box and extends to the bottom of the drive box. A knob is fixedly installed at the bottom end of the worm gear.

[0008] As a preferred technical solution of this application, symmetrically distributed limiting telescopic rods are fixedly installed on the upper side of the inner wall of the inner cylinder, and the driving end of the limiting telescopic rod is fixedly connected to the outer surface of the arc-shaped clamp.

[0009] As a preferred technical solution of this application, an inner limiting ring is provided at one end of the inner cylinder, and an internal threaded sleeve is fixedly installed on the inner side of the inner limiting ring. The internal threaded sleeve is threadedly connected to the outer wall of one end of the inner cylinder, and the outer diameter of the internal threaded sleeve is adapted to the outer diameter of the outer cylinder.

[0010] As a preferred technical solution of this application, the inner cylinder is threadedly connected to a wing bolt through a threaded hole opened on the upper side of its other end inner wall.

[0011] As a preferred technical solution of this application, the bidirectional lead screw is provided with symmetrically distributed left-hand threads and right-hand threads, and the adjusting block is provided with a threaded hole adapted to the bidirectional lead screw. The adjusting block is threadedly connected to the bidirectional lead screw through the threaded hole.

[0012] As a preferred technical solution of this application, the arc-shaped clamp is an elastic clamp, and an anti-slip pad is provided on the inner surface of the arc-shaped clamp.

[0013] As a preferred technical solution of this application, the outer diameter of the outer cylinder and the inner threaded sleeve are adapted to the inner diameter of the air conditioning hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. Through the coordinated use of an inner cylinder, drive box, track, double-acting screw, adjusting block, connecting rod, arc-shaped clamp, limiting telescopic rod, worm gear, knob, and worm wheel, and by incorporating the clamping and adjusting structure integrated within the inner cylinder, and utilizing the cooperation of the worm gear, worm wheel, and double-acting screw, operators can clamp and adjust the air conditioning pipe simply by rotating a knob inside the building. This completely avoids the risk of hand injuries and falls caused by operating in confined spaces near walls or at heights, solving the problem of poor operational safety in existing technologies. Simultaneously, the reverse self-locking characteristics of the worm gear and worm wheel effectively address the shortcomings of double-acting screw rods, such as poor self-locking and easy loosening due to vibration leading to decreased clamping force, thus achieving a durable and stable fixation of the air conditioning pipe.

[0015] 2. By using an outer cylinder, outer limiting ring, inner limiting ring, internal threaded sleeve, and wing bolts in combination, the outer and inner cylinders are slidably connected and then directly locked by the wing bolts. The structure is simple and reliable, avoiding the problem of loosening and failure of the locking block and L-shaped groove due to long-term wear in existing technologies. At the same time, the internal threaded sleeve is used to screw the inner limiting ring to the end of the inner cylinder, so that the outer and inner limiting rings fit tightly against the inner and outer sides of the wall respectively. There is no need for complicated rotation and alignment operations in narrow air conditioning holes, which significantly reduces the installation difficulty, improves the installation efficiency, and ensures the structural stability of the installation components for long-term use.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] Example 1 Please refer to Figures 1-5 An air conditioning hole mounting component for air conditioning pipe installation includes an outer cylinder 1, an inner cylinder 2 that is slidably mounted inside the outer cylinder 1, an outer limiting ring 3 that is fixedly mounted on the outer wall of one end of the outer cylinder 1, a track 7 that is fixedly embedded on the upper side of the inner wall of the inner cylinder 2, a bidirectional screw 8 that is rotatably mounted inside the track 7, and symmetrically distributed adjusting blocks 9 that are sleeved on the outer wall of the bidirectional screw 8 and slidably mounted on the track 7. An arc-shaped clamping plate 11 is provided at the top inside the inner cylinder 2. A symmetrically distributed connecting rod 10 is hinged to the upper side of the outer surface of the arc-shaped clamping plate 11. One end of the connecting rod 10 is hinged to the bottom of the corresponding position adjustment block 9. A drive box 5 is fixedly installed at one end of the inner cylinder 2. An adjustment component is provided inside the drive box 5.

[0023] Furthermore, the adjustment assembly includes a worm gear 14 rotatably mounted inside the drive housing 5, a bidirectional lead screw 8 with one end penetrating the inner cylinder 2 and extending into the drive housing 5, a worm wheel 16 fixedly mounted on one end of the bidirectional lead screw 8, the worm gear 14 meshing with the worm wheel 16, the bottom end of the worm gear 14 penetrating the drive housing 5 and extending to the bottom of the drive housing 5, and a knob 15 fixedly mounted on the bottom end of the worm gear 14.

[0024] Furthermore, symmetrically distributed limiting telescopic rods 13 are fixedly installed on the upper side of the inner wall of the inner cylinder 2, and the driving end of the limiting telescopic rods 13 is fixedly connected to the outer surface of the arc-shaped clamping plate 11. This allows the limiting telescopic rods 13 to provide guidance and support when the arc-shaped clamping plate 11 moves under the drive of the connecting rod 10, preventing the arc-shaped clamping plate 11 from rotating or swaying, and ensuring that the arc-shaped clamping plate 11 always moves in a straight line along the radial direction, thereby maintaining accurate contact with the outer wall of the air conditioning pipe.

[0025] Furthermore, the bidirectional lead screw 8 is provided with symmetrically distributed left-hand and right-hand threads, and the adjusting block 9 has a threaded hole adapted to the bidirectional lead screw 8. The adjusting block 9 is threadedly connected to the bidirectional lead screw 8 through the threaded hole. This allows the two adjusting blocks 9 to move synchronously and at the same speed towards or away from each other along the left-hand and right-hand threads, respectively, when the bidirectional lead screw 8 rotates.

[0026] Furthermore, the arc-shaped clamp 11 is an elastic clamp, and an anti-slip pad is provided on the inner surface of the arc-shaped clamp 11. This allows the arc-shaped clamp 11 to undergo elastic deformation when in contact with the air conditioning pipe, thereby adaptively conforming to the pipe surface. Combined with the anti-slip pad on the inner surface, this increases the coefficient of friction between the clamp and the air conditioning pipe, effectively preventing axial slippage.

[0027] Example 2 The air conditioning hole mounting component for air conditioning pipe installation provided in Embodiment 1 is further optimized. Specifically, an inner limiting ring 4 is provided at one end of the inner cylinder 2, and an internal threaded sleeve 6 is fixedly installed on the inner side of the inner limiting ring 4. The internal threaded sleeve 6 is threaded to the outer wall of one end of the inner cylinder 2, and the outer diameter of the internal threaded sleeve 6 is adapted to the outer diameter of the outer cylinder 1.

[0028] Furthermore, the inner cylinder 2 is threadedly connected to a wing bolt 12 through a threaded hole on the upper side of its other end inner wall. After the inner cylinder 2 is slidably adjusted relative to the outer cylinder 1 to the required length, the wing bolt 12 can be manually tightened so that its end presses against the inner wall of the outer cylinder 1, achieving quick locking and releasing between the inner cylinder 2 and the outer cylinder 1 without the need for any tools, making the operation convenient and the locking reliable.

[0029] Furthermore, the outer diameter of the outer cylinder 1 and the inner threaded sleeve 6 are adapted to the inner diameter of the air conditioning hole. This allows them to fit snugly or with a clearance fit with the inner wall of the air conditioning hole, facilitating the smooth insertion of the installation parts into the air conditioning hole while avoiding wobbling or eccentricity caused by an excessively small outer diameter.

[0030] The usage process of the air conditioning hole mounting component for air conditioning pipe installation provided by this utility model is as follows: In use, firstly, based on the actual length of the air conditioning hole in the wall, since the outer cylinder 1 and the inner cylinder 2 are in a sliding sleeve fit, the inner cylinder 2 can be directly pulled axially to change the overall length between the outer cylinder 1 and the inner cylinder 2, so that the combined length of the two matches the actual depth of the air conditioning hole. After the length is determined, tighten the wing bolt 12 to lock the inner cylinder 2 and the outer cylinder 1 relative to each other and fix them. Then, insert the assembled installation parts into the air conditioning hole port on the outside of the wall, so that one end of the inner cylinder 2 is basically flush with the inner port of the air conditioning hole. Then, insert the inner limiting ring 4 through the inner threaded sleeve 6 from the inside of the wall. The outer limiting ring 3 is directly screwed onto the outer wall of one end of the inner cylinder 2, so that it fits tightly against the wall surface of the outer port of the air conditioning hole, and the inner limiting ring 4 fits tightly against the wall surface of the inner port of the air conditioning hole, thereby completing the axial positioning and fixing of the entire installation component. Subsequently, the air conditioning pipe is passed through the interior of the outer cylinder 1 and the inner cylinder 2. Since the clamping adjustment structure is integrated inside the inner cylinder 2 and operated by the knob 15 located below the bottom of the drive box 5, the operator does not need to reach their hand to the outside of the installation component from the wall or a narrow space at a high position. They only need to screw the knob 15 from the side of the air conditioning hole's inner port inside the building. Button 15 completes the clamping adjustment, completely avoiding the risks of hand scratches against the external wall and falls and scratches caused by leaning out during operation, greatly improving operational safety; when rotating knob 15, knob 15 drives worm gear 14 to rotate, worm gear 14 drives worm wheel 16 to rotate, worm wheel 16 drives double-acting screw 8 to rotate within track 7, the left-hand and right-hand threads symmetrically arranged on double-acting screw 8 drive two adjusting blocks 9 to slide towards or away from each other along the extension direction of track 7, and the adjusting blocks 9 drive the arc-shaped connecting rod 10 at their bottom to move... The clamping plate 11 moves towards or away from the axis of the air conditioning pipe. At the same time, the limiting telescopic rod 13 guides and limits the movement trajectory of the arc-shaped clamping plate 11. The anti-slip pad on the inner surface of the arc-shaped clamping plate 11 contacts the outer wall of the air conditioning pipe and applies a uniform clamping force. Since the worm gear 14 and the worm wheel 16 have a reverse self-locking characteristic, even if the air conditioner generates continuous vibration during operation, it cannot drive the worm gear 14 to rotate in the reverse direction. This effectively solves the problems of poor self-locking performance and easy attenuation of clamping force in the existing technology of bidirectional threaded rods, and achieves a durable, stable and reliable fixation of the air conditioning pipe.
