Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, specifically to a clamping mechanism for air conditioning energy-saving retrofit. Background Technology

[0002] Air conditioning energy-saving retrofit refers to the process of optimizing and upgrading existing air conditioning systems through technical means to reduce energy consumption, improve energy efficiency, and reduce operating costs. The retrofit usually includes, but is not limited to, the following aspects: replacing compressors, fans, or heat exchangers with high energy efficiency ratios; improving refrigerant piping layout, adding insulation layers, or cleaning condensers / evaporators; installing frequency converters, waste heat recovery devices, or solar auxiliary systems; and regularly cleaning filters and condensers, etc. Energy-saving retrofit can significantly reduce the energy consumption of air conditioning systems (usually achieving energy savings of 10%-30%), while extending equipment life and reducing carbon emissions.

[0003] During the energy-saving renovation of air conditioning, it is necessary to disassemble, clean, replace or adjust components such as outdoor air conditioning units, pipes, and valves. The clamps used in traditional renovations are mostly fixed structures. These fixed clamps cannot be rotated or moved. In some renovation sites with limited space (such as the exterior walls of residential buildings or inside machine rooms), it is necessary to repeatedly disassemble and re-fix air conditioning components to adjust the operating angle, which is inefficient and poses safety hazards.

[0004] To address these issues, we designed an air conditioning energy-saving retrofit clamping mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide an air conditioning energy-saving retrofit clamping mechanism to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides an air conditioner energy-saving retrofit clamping mechanism, including a hollow structure box with a vertically penetrating storage channel at the center of its top. A clamping mechanism is provided inside the box, and a driving mechanism is connected to the bottom end of the clamping mechanism. The clamping mechanism includes:

[0007] A ring-shaped toothed disc is horizontally rotatably connected to the inner arc wall of the storage channel. Multiple vertically penetrating sliding channels are arranged in a ring array about its axial direction and extend radially along the ring-shaped toothed disc. A horizontal sliding plate is slidably connected in the sliding channel. One end of the sliding plate near the ring-shaped toothed disc extends to the outside of the sliding channel and is fixed with a limit plate. The other end slides against a horizontal fixed disc. A vertically arranged gear is engaged on one side of the bottom of the ring-shaped toothed disc. The gear does not contact the fixed disc.

[0008] The second ring-shaped gear disk is coaxially fixed to the bottom of the first fixed disk. The bottom end of the second gear is meshed with the first gear. The first gear and the second gear are coaxially arranged. The same drive mechanism is fixed to the ends of the first gear and the second gear away from the axis of the second ring-shaped gear disk.

[0009] Furthermore, the fixed disk one has multiple arc-shaped grooves arranged in a circular array along the axis of the fixed disk one on one side wall near the annular gear disk one. One end of the arc-shaped groove is set towards the axis of the fixed disk one, and the other end is bent towards the edge of the fixed disk one. The multiple arc-shaped grooves correspond one-to-one with multiple sliding channels. Vertically arranged sliding columns are fixed on the side walls of the sliding plate near the annular gear disk one and the fixed disk one, respectively. Two sliding columns fixed on the same sliding plate are coaxially arranged. The sliding columns on both sides of the sliding plate slide in the sliding channels and the corresponding arc-shaped grooves, respectively. A handle is fixed on one side of the outer side wall of the box. Self-locking universal wheels are installed at the four corners of the bottom of the box. The gear one and the gear two are coaxially arranged on the side wall away from the axis of the annular gear disk two, respectively. The gear one is rotatably connected to the transmission shaft, and the gear two is fixedly connected to the transmission shaft. A motor is fixed on the end of the transmission shaft away from the gear two.

[0010] Furthermore, a splined shaft is fixed on the outer arc wall of the transmission shaft fixed to the output end of the motor, located between the motor and the second fixed disk. A turntable is slidably sleeved on the outer side of the splined shaft. The second fixed disk is coaxially fixed on the side wall of the gear one near the turntable. The second fixed disk is rotatably sleeved on the outside of the transmission shaft. Multiple limiting posts are fixed on the outer edge of the side wall of the turntable near the second fixed disk, arranged in a circular array about the axis of the turntable. The axis of the limiting posts is parallel to the axis of the turntable. An electric push rod is provided on one side of the motor. The output end of the electric push rod is in the same direction as the output end of the motor. A limiting clamp is fixed on the output end of the electric push rod. The limiting clamp has a "door" shaped cross section along the radial direction of the turntable, with the notch facing the turntable. The edge of the turntable rotates within the limiting clamp. Multiple limiting grooves are opened on the side wall of the second fixed disk near the turntable, arranged in a circular array about the axis of the second fixed disk. The multiple limiting grooves correspond one-to-one with the multiple limiting posts.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The clamping mechanism is rotated as a whole by the drive mechanism, so that air conditioning components such as outdoor units and pipes can be adjusted in angle without disassembly during the modification process. The combination design of the ring toothed plate and the sliding plate allows the clamping mechanism to adapt to components of different sizes, and the clamping position can be adjusted by sliding, making it more compatible.

[0022] 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.

[0023] Please see the appendix Figure 1 To be continued Figure 4 This utility model provides a technical solution: an air conditioner energy-saving retrofit clamping mechanism, including a hollow box 10 with a vertically penetrating storage channel at the center of its top. The box 10 contains a clamping mechanism, and a driving mechanism is connected to the bottom of the clamping mechanism. The clamping mechanism includes:

[0024] The annular toothed disc 20 is horizontally rotatably connected to the inner arc wall of the storage channel. Multiple vertically penetrating sliding channels are arranged in a circular array about its axis and extend radially along the annular toothed disc 20. A horizontal sliding plate 24 is slidably connected in the sliding channel. One end of the sliding plate 24 near the annular toothed disc 20 extends to the outside of the sliding channel and is fixed with a limit plate 13. The other end slides against a horizontal fixed disc 25. A vertically arranged gear 21 is engaged on one side of the bottom end of the annular toothed disc 20. The gear 21 does not contact the fixed disc 25.

[0025] The second ring gear disk 22 is coaxially fixed to the bottom of the first fixed disk 25. The bottom end of the second ring gear disk 22 is meshed with the vertically arranged second gear 23 near the first gear 21. The first gear 21 and the second gear 23 are coaxially arranged. The same drive mechanism is fixed to the end of the first gear 21 and the second gear 23 away from the axis of the second ring gear disk 22.

[0026] The fixed disk 25 has multiple arc-shaped grooves arranged in a ring array along the axial direction of the fixed disk 25 on one side wall near the annular toothed disk 20. One end of the arc-shaped groove is set towards the axis of the fixed disk 25, and the other end is bent towards the edge of the fixed disk 25. The multiple arc-shaped grooves correspond one-to-one with multiple sliding channels.

[0027] The slide plate 24 is fixed with vertically arranged sliding columns on the side walls of the ring toothed disc 20 and the fixed disc 25 respectively. The two sliding columns fixed on the same slide plate 24 are coaxially arranged. The sliding columns on both sides of the slide plate 24 slide in the sliding channel and the corresponding arc-shaped sliding groove respectively. A handle 12 is fixed on the outer side wall of one side of the box body 10. Self-locking universal wheels 11 are installed at the four corners of the bottom of the box body 10.

[0028] In practice, considering the overall load-bearing capacity, the self-locking caster wheel 11 can be made of metal to provide sufficient support;

[0029] The annular gear disk 20 is horizontally rotatably connected to the inner arc wall of the storage channel. Its top is flush with the top plane of the box 10. Multiple radial sliding channels are opened on the top of the annular gear disk 20 for the slide plate 24 to slide. The bottom end meshes with the gear 21. The rotation of the gear 21 drives the annular gear disk 20 to rotate. The slide plate 24 is slidably connected in the sliding channel. One end is fixed with the limiting plate 13, and the other end is connected with the arc-shaped sliding groove of the fixed disk 25 through the sliding column. The rotational motion of the fixed disk 25 is converted into the radial sliding of the slide plate 24, thereby realizing the adjustment of the clamping radius. When the gear 21 and the gear 23 rotate synchronously, the annular gear disk 20 and the fixed disk 25 rotate synchronously. At this time, the clamping radius remains unchanged, and the clamping mechanism rotates as a whole.

[0030] When the fixed plate 25 rotates, the arc-shaped groove on it rotates accordingly, which in turn drives the sliding column at the bottom of the slide plate 24 to move. However, since the sliding column at the top of the slide plate 24 is located in the sliding channel, the existence of the sliding channel limits the movement trajectory of the slide plate 24. That is, the slide plate 24 can only slide along the sliding channel section, thereby adjusting the clamping position of the slide plate 24.

[0031] See appendix Figure 1 To be continued Figure 4 The gear 21 and the gear 23 are coaxially connected to the same transmission shaft on one side wall away from the axis of the annular gear disk 22. The gear 21 is rotatably connected to the transmission shaft, and the gear 23 is fixedly connected to the transmission shaft. A motor 30 is fixed to the end of the transmission shaft away from the gear 23.

[0032] A spline shaft 31 is fixed on the outer arc wall of the transmission shaft fixed to the output end of the motor 30, located between the motor 30 and the second fixed disk 34. A turntable 32 is slidably sleeved on the outside of the spline shaft 31. A second fixed disk 34 is coaxially fixed on the side wall of the gear 1 21 near the turntable 32. The second fixed disk 34 is rotatably sleeved on the outside of the transmission shaft. A plurality of limiting posts 33 are fixed on the outer edge of the side wall of the turntable 32 near the second fixed disk 34, which are arranged in a ring array about the axis of the turntable 32. The axis of the limiting posts 33 is parallel to the axis of the turntable 32.

[0033] An electric push rod 35 is provided on one side of the motor 30. The output end of the electric push rod 35 is in the same direction as the output end of the motor 30. A limit clamp 36 is fixed to the output end of the electric push rod 35. The limit clamp 36 has a "door" shaped cross section along the radial direction of the turntable 32 and the notch is set facing the turntable 32. The edge of the turntable 32 rotates within the limit clamp 36. Multiple limit grooves are provided on the side wall of the fixed disk 34 near the turntable 32, arranged in a ring array along the axial direction of the fixed disk 34. The multiple limit grooves correspond one-to-one with the multiple limit posts 33.

[0034] In specific implementation, based on the above implementation, the inner sidewalls of the limiting clamps 36 that are close to each other are fitted with balls, and the turntable 32 rolls against the balls. The balls are used to reduce the friction between the turntable 32 and the inner wall of the limiting clamp 36 when the limiting clamps 36 move along the spline shaft 31.

[0035] With the cooperation of turntable 32 and spline shaft 31, turntable 32 can not only slide freely along the axial direction of spline shaft 31, but the transmission shaft can also transmit its own torque to turntable 32 through spline shaft 31. When the limit post 33 is not inserted into the limit groove on the fixed plate 2 34, the motor 30 directly drives the transmission shaft to drive gear 23 and then drive the fixed plate 1 25 to rotate, driving the four limit plates 13 to change their position and change the clamping radius.

[0036] When the electric push rod 35 pushes the limit clamp 36 to drive the turntable 32 to move along the drive shaft axis, the turntable 32 drives the limit post 33 to move toward the fixed plate 34. The limit groove on the side wall of the fixed plate 34 near the turntable 32 is arc-shaped, and the depth of the inner side wall of the limit groove away from the turntable 32 gradually decreases and smoothly transitions along the working rotation direction, which makes it easier for the limit post 33 to be inserted into the limit groove in the rotating state.

[0037] When the limiting pin 33 is inserted into the limiting groove, the fixed plate 34 and the turntable 32 are linked by the limiting pin 33. At this time, the fixed plate 34 will receive the torque transmitted from the turntable 32. Thus, the fixed plate 34 will rotate synchronously with the turntable 32. Since the fixed plate 34 drives the gear 21 to rotate, the gear 21 and the gear 23 rotate synchronously, which in turn drives the annular gear disk 20 and the fixed plate 25 to rotate synchronously. Therefore, the clamping mechanism will no longer be triggered to rotate along the axial direction of the annular gear disk 20, maintaining stability during rotation.

[0038] Working principle: Motor 30 drives the transmission shaft to rotate, which drives the gear 23 fixedly connected to the transmission shaft to rotate. Gear 23 meshes with the ring gear disk 22, causing the fixed disk 25 fixed on the same axis to rotate. The arc-shaped groove of the fixed disk 25 drives the sliding column of the slide plate 24. Because the sliding column at the other end of the slide plate 24 is restricted by the sliding channel of the ring gear disk 20, the slide plate 24 slides radially along the sliding channel, and the limiting plate 13 moves accordingly to adjust the clamping radius.

[0039] When the entire clamping mechanism needs to be rotated, the electric push rod 35 pushes the limit clamp 36, causing the turntable 32 to slide along the spline shaft 31, so that the limit post 33 of the turntable 32 is inserted into the limit groove of the fixed disk 2 34. At this time, the turntable 32 drives the fixed disk 2 34 and the gear 1 21 to rotate. The gear 1 21 meshes with the annular gear disk 20, so that the annular gear disk 20 and the fixed disk 25 rotate synchronously, realizing the overall rotation of the clamping mechanism while the clamping radius remains unchanged.
