[0048] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0049] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0050] Currently, during the installation of air conditioning units, pipe fixing brackets are widely used to support and fix refrigerant pipes, drain pipes, and other pipes.

[0051] The existing pipe fixing method usually uses a combination of metal brackets and pipe clamps. These brackets and pipe clamps are fixed to the wall or other structures by bolts, buckles and other means.

[0052] However, existing fixing methods use rigid connections, which may cause excessive stress concentration at certain points, leading to pipe deformation or damage, especially in environments with high vibration. Furthermore, when the pipe vibrates significantly, the pipe clamps may loosen, causing the pipe fixing to fail.

[0053] Therefore, as Figures 1-2 As shown, this utility model proposes a pipe fixing device that can prevent pipe loosening and stress damage caused by vibration, comprising:

[0054] Base 10;

[0055] A linear mechanism 20 is disposed on the base 10;

[0056] The moving platform 30 is connected to the output end of the linear mechanism 20;

[0057] Pipe fixing component 40 is disposed on one side of the moving platform 30 along the moving direction of the linear mechanism 20; the pipe fixing component 40 is used to fix the pipe 70;

[0058] Pressure detection assembly 50 is mounted on a moving platform 30 located within the pipeline fixture 40;

[0059] The linear mechanism 20 drives the moving platform 30 to move axially based on the pressure value detected by the pressure detection component 50.

[0060] It should be noted that the pipe fixing device proposed in this embodiment is illustrated by its application on an air conditioning unit. Of course, the pipe fixing device can also be applied to other equipment with pipes installed, and is not limited here. The pressure detection component 50 proposed in this embodiment is preferably a pressure sensor, and the pressure detection component 50 is used to detect the pre-tightening pressure value of the pipe 70 fixed by the pipe fixing component 40; and the moving platform 30 is set with the side wall where the pipe fixing component 40 is located as a plane, which facilitates the placement of the pipe 70. The linear mechanism 20 proposed in this embodiment is illustrated by its movement in the vertical direction, and the linear mechanism 20 is preferably a linear mechanism 2i (i = 1...8). Of course, the linear mechanism 20 can also move in the horizontal direction, and is not limited here; and the pipe fixing device proposed in this embodiment also includes a control unit (not shown, the same throughout), which is electrically connected to the linear mechanism 20 and the pressure detection component 50 respectively.

[0061] In this way, the installer first uses the linear mechanism 20 to raise the moving platform 30 until it just touches the pipe 70, and then uses the pipe fixing component 40 to fix the pipe 70 on the moving platform 30. At this time, the pressure detection component 50 is located between the moving platform 30 and the pipe 70 and is pressed against each other. Then the linear mechanism 20 will drive the moving platform 30 to make a slight movement so that the pressure value detected by the pressure detection component 50 reaches the preset pressure value (that is, the pre-tightening pressure value of the pipe 70 reaches the preset pressure value), indicating that the pipe 70 is effectively fixed and the pipe fixing component 40 fixes the pipe 70 with the best stability.

[0062] Thus, when vibration or other external disturbances occur at the location of the pipeline fixing device, the following two situations will occur:

[0063] Firstly, if the pressure value detected by the pressure detection component 50 is greater than the preset pressure value within a preset time, it indicates that the pressure on the pipeline 70 exceeds the preset pressure value. In other words, the pipeline 70 is subjected to excessive pressure from the pipeline fixing component 40, resulting in compressive stress. If the pipeline 70 operates in this state for a long time, the following consequences will occur:

[0064] (1) Excessive compressive stress will cause plastic deformation of the pipe 70, which will affect the fluid flow in the pipe 70 and reduce the working efficiency of the system equipped with the pipe 70.

[0065] (2) Excessive compressive stress may cause stress concentration on the pipe wall of pipe 70, resulting in local damage such as microcracks or scratches. These damages may gradually expand over time, eventually leading to pipe 70 rupture or leakage.

[0066] (3) Long-term exposure to excessive compressive stress will cause fatigue in the materials used to manufacture the pipe 70, accelerating the aging process of the materials. Even if there are no obvious problems in the short term, it will affect the service life of the pipe 70 in the long term.

[0067] Therefore, when the control unit receives the high-voltage electrical signal from the pressure detection component 50, it will activate the linear mechanism 20 so that the linear mechanism 20 drives the moving platform 30 to slowly descend until the pressure value detected by the pressure detection component 50 drops to the preset pressure value. Only then will the control unit close the linear mechanism 20 so that the moving platform 30 maintains its current height. This dynamically adjusts the pre-tightening pressure value of the pipeline 70 to maintain the preset pressure value, thereby effectively preventing the pipeline 70 from deforming or being damaged due to excessive vibration.

[0068] Secondly, if the pressure value detected by the pressure detection component 50 is lower than the preset pressure value within a preset time, it indicates that the pressure on the pipeline 70 is lower than the preset pressure value. That is, the pipeline 70 is not receiving or is about to lose pressure from the pipeline fixing component 40. If the pipeline 70 operates in this state for a long time, the following consequences will occur:

[0069] (1) If the pipeline 70 is not effectively secured, it may shake due to the flow of fluid in the pipeline 70 or the vibration of the equipment during operation. This will not only generate additional noise, but may also cause fatigue damage to the pipeline 70.

[0070] (2) If the pipe 70 is broken or the interface is loose due to lack of fixation, the fluid in the pipe 70 will leak.

[0071] (3) The pipeline 70 is not effectively secured and is in an unstable state for a long time, which may affect the structural stability and service life of the entire equipment. Especially in outdoor units, wind pressure and temperature changes may exacerbate this situation.

[0072] Therefore, upon receiving the low-pressure electrical signal from the pressure detection component 50, the control unit activates the linear mechanism 20. This mechanism slowly raises the moving platform 30 until the pressure detected by the pressure detection component 50 reaches the preset pressure value. Only then does the control unit deactivate the linear mechanism 20, maintaining the moving platform 30 at its current height. This dynamic adjustment keeps the pre-tightening pressure of the pipeline 70 at the preset value, causing dynamic changes in the support force of the pipeline 70. This prevents damage to the pipeline 70 due to ineffective fixation, reduces alternating stress, extends the fatigue life of the pipeline 70, and improves equipment stability. It also eliminates pipeline swaying caused by fluid flow or equipment vibration, reducing noise. Furthermore, it avoids the risk of leakage due to pipeline 70 breakage or loose connections, preventing environmental pollution or safety accidents caused by fluid leakage and improving the sealing and safety of the pipeline 70. Even in extreme cases—when the pipeline fixing component 40 is completely loose—the dynamic adjustment ensures that the pipeline 70 is supported by the moving platform 30, further guaranteeing the operational reliability of the equipment.

[0073] Therefore, this utility model uses the pressure value detected in real time by the pressure detection component 50 to control the linear mechanism 20 to dynamically adjust the height of the pipe fixing component 40, so that the supporting force of the pipe 70 changes dynamically. This keeps the pre-tightening pressure value of the pipe 70 fixed by the pipe fixing component 40 dynamically at the preset pressure value, thereby effectively preventing the pipe 70 from deforming or being damaged due to excessive vibration, ensuring that the pipe fixing component 40 can effectively fix the pipe 70, improving the sealing and safety of the pipe 70, and extending the service life of the pipe 70.

[0074] In some embodiments, to ensure that the linear mechanism 20 can stably drive the driving platform 30 to move up and down along the axial direction, such as... Figure 1 and Figure 3 As shown, the linear mechanism 20 includes a drive assembly 201, a transmission link 202, and a first guide slider 203;

[0075] The driving component 201 is provided on the top of the base 10. The output end of the driving component 201 is connected to the transmission link 202. The transmission link 202 and the first guide slider 203 are matched to form a sliding pair. The first guide slider 203 is connected to the moving platform 30.

[0076] It should be noted that the drive component 201 proposed in this embodiment is preferably a servo motor. After receiving the instructions from the control unit, the servo motor can provide real-time feedback of position / speed through the encoder to form closed-loop control and achieve micron-level positioning accuracy.

[0077] In this way, when the control unit starts the drive assembly 201, the drive assembly 201 will drive the transmission link 202 to rotate, thereby causing the first guide slider 203 to move axially up and down along the transmission link 202. This, in turn, causes the moving platform 30 connected to the first guide slider 203 to move axially up and down, thereby dynamically adjusting the height of the pipe fixing component 40. This causes the support force of the pipe 70 to change dynamically, so that the pre-tightening pressure value of the pipe 70 fixed by the pipe fixing component 40 is dynamically maintained at the preset pressure value. This effectively prevents the pipe 70 from deforming or being damaged due to excessive vibration, ensures that the pipe fixing component 40 can effectively fix the pipe 70, improves the sealing and safety of the pipe 70, and extends the service life of the pipe 70.

[0078] In other embodiments, the moving platform 30 is preferably a hollow structure, thereby reducing the load inertia of the linear mechanism 20 and reducing the energy consumption requirement of the linear mechanism 20.

[0079] In some embodiments, to constrain the radial displacement of the transmission link 202, such as... Figure 1 As shown, the linear mechanism 20 also includes a first limiting seat 204;

[0080] The base 10 is provided with a first limiting seat 204 corresponding to the bottom end of the transmission link 202, and the bottom end of the transmission link 202 is rotatably connected to the first limiting seat 204.

[0081] It should be noted that the first limiting seat 204 proposed in this embodiment uses paired angular contact ball bearings (mounted back-to-back or face-to-face) to form a closed bearing seat structure. The inner ring of the angular contact ball bearing is interference-fitted or pre-tightened with the transmission connecting rod 202, and the bottom end of the transmission connecting rod 202 is axially locked inside the first limiting seat 204 by a collar and a lock nut, achieving bidirectional axial fixation. Of course, a dustproof seal ring is also matched at the interference fit between the inner ring of the angular contact ball bearing and the transmission connecting rod 202 to prevent debris from entering the bearing area.

[0082] In some embodiments, to further constrain the radial displacement of the transmission link 202, such as Figure 1 As shown, the linear mechanism 20 also includes a second limiting seat 205;

[0083] The base 10 is provided with a second limiting seat 205 corresponding to the upper part of the transmission link 202, and the transmission link 202 passes through the second limiting seat 205 and is rotatably connected to it.

[0084] It should be noted that the second limiting seat 205 proposed in this embodiment is fitted with a deep groove ball bearing, which is essentially a through-hole bearing seat design. The transmission connecting rod 202 can directly pass through the inner hole of the bearing and extend to the outside of the second limiting seat 205. The inner ring of the deep groove ball bearing is either clearance-fitted or floatingly mounted with the transmission connecting rod 202. Of course, a limiting retaining ring or snap ring is also matched at the clearance fit between the inner ring of the deep groove ball bearing and the transmission connecting rod 202 to prevent the transmission connecting rod 202 from axially moving out, while retaining space for thermal expansion and contraction. A dustproof sealing ring is also matched at the clearance fit between the inner ring of the deep groove ball bearing and the transmission connecting rod 202 to prevent debris from entering the bearing area.

[0085] In some embodiments, such as Figure 1 As shown, the linear mechanism 20 also includes a coupling 206;

[0086] The output end of the drive assembly 201 is connected to the transmission link 202 via the coupling 206.

[0087] In this way, the coupling 206 transmits the torque of the drive assembly 201 and compensates for minor installation deviations (such as radial / angular deviations) between the output shaft (equivalent to the output end, the same throughout the text) of the drive assembly 201 and the shaft of the transmission link 202.

[0088] In some embodiments, to ensure that the first guide slider 203 restricts its rotational degree of freedom when the drive linkage 202 rotates, and to ensure that the first guide slider 203 only moves in a linear fashion, such as... Figures 3-4 As shown, the pipeline fixing device also includes a guide mechanism 60 disposed on the base 10, and the sliding end of the guide mechanism 60 is connected to the moving platform 30.

[0089] Thus, when the drive assembly 201 drives the transmission link 202 to rotate, the first guide slider 203 will be restricted by the guide mechanism 60 to move only in a straight line. That is, when the transmission link 202 rotates, a tangential force is generated at the connection point between its outer periphery and the first guide slider 203. This tangential force will be decomposed into an axial component force with the cooperation of the guide mechanism 60 to push the first guide slider 203 to move in a straight line, thereby enabling the moving platform 30 connected to the first guide slider 203 to move only in a straight line.

[0090] In a further embodiment, to ensure that the guide mechanism 60 can stably restrict the rotational degree of freedom of the first guide slider 203, and to ensure that the first guide slider 203 only performs linear movement, such as... Figure 3 As shown, the guiding mechanism 60 includes a guide rail 601 and a second guide slider 602;

[0091] The guide rail 601 is disposed on the base 10, and the extending direction of the guide rail 601 is parallel to the moving direction of the linear mechanism 20.

[0092] The guide rail 601 and the second guide slider 602 are matched to form a sliding pair, and the second guide slider 602 is connected to the moving platform 30.

[0093] In this way, the sliding pair formed by the guide rail 601 and the second guide slider 602 can not only restrict the moving platform 30 to only move in a straight line, but also improve the smoothness of the moving platform 30 sliding in the axial direction.

[0094] Of course, in other embodiments, the guide mechanism 60 can also be a "guide rod + linear bearing" structure, which is not limited here.

[0095] In a further embodiment, the transmission connecting rod 202 is a lead screw, and the first guide slider 203 is a lead screw nut;

[0096] The lead screw passes through the lead screw nut and is connected to the ball bearing assembly inside the lead screw nut;

[0097] The drive assembly 201 drives the lead screw to rotate, and the lead screw nut converts the rotational motion of the lead screw into linear motion through the cyclic rotation of the ball assembly, so as to move the lead screw nut axially along the lead screw.

[0098] In this way, when the drive assembly 201 drives the lead screw to rotate, the lead screw nut rotates cyclically through the ball assembly, and with the cooperation of the guide mechanism 60, the rotational motion of the lead screw is converted into linear motion, so that the lead screw nut moves axially up and down along the lead screw, thereby dynamically adjusting the height of the pipeline fixing component 40. This causes the support force of the pipeline 70 to change dynamically, so that the pre-tightening pressure value of the pipeline 70 fixed by the pipeline fixing component 40 is dynamically maintained at the preset pressure value. This effectively prevents the pipeline 70 from being deformed or damaged due to excessive vibration, ensures that the pipeline fixing component 40 can effectively fix the pipeline 70, improves the sealing and safety of the pipeline 70, and extends the service life of the pipeline 70.

[0099] Specifically, the external thread groove of the lead screw and the internal thread groove of the lead screw nut together form a closed raceway. The ball assembly is completely constrained within the closed raceway and can only roll along the helical path. When the lead screw rotates, the side wall of its external thread groove applies a thrust to the ball assembly, which then transmits the force to the raceway wall of the lead screw nut, pushing the lead screw nut to move linearly along the lead screw axis. In this way, the ball assembly acts as an intermediary, converting the rotational force of the lead screw into the linear thrust of the lead screw nut, while also bearing the shear force itself.

[0100] Of course, the end of the lead screw nut is equipped with a reverser or guide tube to change the direction of movement of the ball assembly, thereby forming a closed loop path; in this way, the reverser or guide tube ensures that the ball assembly can return to the starting point after reaching the end of the lead screw nut, maintain continuous rolling, and avoid jamming.

[0101] In other embodiments, the transmission link 202 can also be a worm gear structure; in this way, when the drive assembly 201 drives the worm to rotate, the helical teeth of the worm drive the worm wheel teeth to mesh one by one, and the first guide slider 203, which is rigidly connected to the incomplete gear ring on the outer periphery of the worm wheel through a threaded hole or keyway, will only move linearly with the cooperation of the guide mechanism 60, thereby dynamically adjusting the height of the pipeline fixing component 40.

[0102] Of course, in other embodiments, the transmission link 202 may also be a rack and pinion structure or other structures that facilitate the conversion of rotational motion into linear motion, which is not limited here.

[0103] In some embodiments, to ensure the reusability of the pipeline fixing device, the pipeline fixing member 40 is detachably connected to the moving platform 30.

[0104] Specifically, the pipe fixing component 40 proposed in this embodiment is preferably a U-shaped component. The concave area of ​​the U-shaped component is used to accommodate the pipe 70, and the two ends of the U-shaped component are fixed to the moving platform 30 by anti-vibration bolts.

[0105] This utility model also proposes an air conditioning unit, which includes the aforementioned pipe fixing device.

[0106] In this way, the installer first uses the linear mechanism 20 to raise the moving platform 30 until it just touches the pipe 70, and then uses the pipe fixing component 40 to fix the pipe 70 on the moving platform 30. At this time, the pressure detection component 50 is located between the moving platform 30 and the pipe 70 and is pressed against each other. Then the linear mechanism 20 will drive the moving platform 30 to make a slight movement so that the pressure value detected by the pressure detection component 50 reaches the preset pressure value (that is, the pre-tightening pressure value of the pipe 70 reaches the preset pressure value), indicating that the pipe 70 is effectively fixed and the pipe fixing component 40 fixes the pipe 70 with the best stability.

[0107] If the pressure value detected by the pressure detection component 50 is greater than the preset pressure value within a preset time, the control unit will activate the linear mechanism 20. The linear mechanism 20 will then drive the moving platform 30 to slowly descend until the pressure value detected by the pressure detection component 50 drops to the preset pressure value. Only then will the control unit deactivate the linear mechanism 20 to maintain the moving platform 30 at its current height. This dynamic adjustment keeps the pre-tightening pressure value of the pipe 70 at the preset pressure value, causing the support force of the pipe 70 to change dynamically. This effectively prevents the pipe 70 from deforming or being damaged due to excessive vibration, improving the stability and reliability of the air conditioning unit and significantly extending the service life of the pipe 70 and the entire air conditioning unit. It also avoids frequent repairs due to pipe 70 damage or equipment failure, thus greatly reducing maintenance costs. This ensures the continuous and stable operation of the air conditioning unit, providing users with a more comfortable and reliable user experience.

[0108] If the pressure value detected by the pressure detection component 50 is less than the preset pressure value within a preset time, the control unit will activate the linear mechanism 20. This mechanism will slowly raise the moving platform 30 until the pressure value detected by the pressure detection component 50 increases to the preset pressure value. Only then will the control unit deactivate the linear mechanism 20 to maintain the moving platform 30 at its current height. This dynamic adjustment maintains the pre-tightening pressure of the pipe 70 at the preset pressure value, causing dynamic changes in the support force of the pipe 70. This prevents damage to the pipe 70 due to ineffective fixation, reduces alternating stress, extends the fatigue life of the pipe 70, and improves equipment stability. It also eliminates pipe swaying caused by fluid flow or air conditioning unit vibration, reducing noise. Furthermore, it avoids the risk of leakage due to pipe 70 breakage or loose connections, preventing environmental pollution or safety accidents caused by fluid leakage and improving the sealing and safety of the pipe 70. Even in extreme cases—when the pipe fixing component 40 is completely loose—the dynamic adjustment ensures that the pipe 70 is supported by the moving platform 30, further guaranteeing the operational stability and reliability of the air conditioning unit.
