Description
Technical Field
[0001] This utility model relates to the field of electromechanical engineering equipment technology, specifically to a flexible connection vibration reduction and noise reduction structure for electromechanical air conditioning pipes. Background Technology
[0002] The flexible connection vibration reduction and noise reduction structure for electromechanical air conditioning ducts refers to a special structural device applied to electromechanical air conditioning systems. It uses elastic and deformable components at the duct connection or support points, combined with a stable fixing assembly and a convenient disassembly structure, to absorb the vibration energy generated by equipment vibration and fluid disturbance during duct operation, block the transmission of vibration to the building structure or other equipment, and reduce environmental noise caused by vibration and airflow and water flow noise. At the same time, it takes into account the stability of duct installation and the convenience of later maintenance.
[0003] However, in practical applications, the connection of electromechanical air conditioning pipes is usually made using bolts. When the pipes vibrate, the supporting parts sway from side to side, which can loosen the bolts and cause the supporting parts to vibrate and produce metallic noise. Therefore, maintenance is often required. Thus, there is a need to provide a flexible connection structure for electromechanical air conditioning pipes to reduce vibration and noise. Utility Model Content
[0004] The purpose of this utility model is to provide a flexible connection structure for electromechanical air conditioning ducts to reduce vibration and noise, thereby solving the problems mentioned in the background section. To solve these technical problems, this utility model is achieved through the following technical solution:
[0005] This utility model is a flexible connection vibration reduction and noise reduction structure for electromechanical air conditioning pipes, including:
[0006] The fixing component includes a fixing base fixed to the ground, a lower fixing post screwed to the center of the upper end of the fixing base, a protective shell screwed to the upper end of the lower fixing post, an upper fixing post slidably connected to the center of the upper end of the protective shell, and a bracket screwed to the center of the upper end of the upper fixing post.
[0007] The buffer component includes a fixed outer ring fixed to the center of the bottom of the inner side of the protective shell, a fixed inner ring located inside the fixed outer ring, and an upper fixed post fixed through the middle of the fixed inner ring.
[0008] Furthermore, the buffer component also includes a fixing ring fixed to the four sides of the inner ring of the outer ring and a memory spring welded to the inner ring of the fixing ring, with fixing rings fixed to both ends of the memory spring.
[0009] Furthermore, the buffer component also includes a limiting plate sleeved on the outer ring of the bottom end of the upper fixing post, and one end of the fixing ring is fixed in the center of the outer ring of the inner fixing ring.
[0010] Furthermore, the buffer component also includes a hole in the center of the upper end of the protective shell, the bottom end of the upper fixing post passes through the hole, and the limiting plate is larger than the area of the hole and is located at the lower end of the hole.
[0011] Furthermore, it also includes a quick-release component, which includes a slot in the center of the upper end of the bracket, a mounting groove in the center of both ends of the slot, torsion springs welded to both ends inside the mounting groove, and irregularly shaped claws welded to the center of the two torsion springs.
[0012] Furthermore, the quick-release component also includes an insertion interface on one side of the upper end of the irregular claw and a rubber plug inserted into the insertion interface.
[0013] Furthermore, the quick-release component also includes a fixing rod inserted into the insertion interface, the irregularly shaped claws are in a staggered state, and the two ends of the fixing rod are respectively inserted into the two insertion interfaces.
[0014] This invention offers the following advantages: When a pipeline vibrates, the vibration is first transmitted to the bracket directly supporting the pipeline, causing the bracket to sway left and right. The bracket then transmits the vibration to the upper fixed column, which is bolted to it, preparing to move. Because the upper fixed column is fixed to the inner ring, the inner ring moves synchronously with the upper fixed column, thereby pulling or compressing the memory spring. The memory spring absorbs the vibration energy through its own deformation, weakening the vibration intensity. After being buffered by the memory spring, the remaining minor vibration is transmitted sequentially to the protective shell, the lower fixed column, and finally to the fixed base on the ground. At this point, the vibration has been significantly reduced, preventing it from causing significant vibration to the building structure, thus ensuring structural protection. During the process, the hole at the top of the protective shell provides a movement channel for the upper fixed column, and the limiting plate restricts the movement range of the upper fixed column to prevent it from coming loose. The fixed ring maintains a stable connection between the memory spring and other components, ensuring the entire process proceeds stably, ultimately achieving vibration reduction and noise reduction. This invention solves the problem of lateral swaying of the pipeline on the connecting support components, which leads to loose bolt connections and loss of support effect, through the buffer component.

[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] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0024] Please see Figure 1-4 As shown, this utility model is a flexible connection vibration reduction and noise reduction structure for electromechanical air conditioning ducts, comprising:
[0025] The fixing components include a fixing base 10 fixed to the ground, a lower fixing post 11 screwed to the center of the upper end of the fixing base 10, a protective shell 12 screwed to the upper end of the lower fixing post 11, an upper fixing post 13 slidably connected to the center of the upper end of the protective shell 12, and a bracket 14 screwed to the center of the upper end of the upper fixing post 13.
[0026] The buffer component includes a fixed outer ring 20 fixed in the center of the bottom of the inner side of the protective shell 12, a fixed inner ring 21 located in the inner circle of the fixed outer ring 20, and an upper fixed post 13 fixed through and in the middle of the fixed inner ring 21.
[0027] The mounting base 10 is used to fix the pipe and the whole structure to the ground, providing stable support for the entire structure; the lower mounting column 11 is connected to the mounting base 10 and the protective shell 12 by screws, playing a connecting role; the protective shell 12 can protect the internal buffer components and prevent them from being affected by the outside world; the upper mounting column 13 can slide inside the protective shell 12 and can also connect the buffer components and the bracket 14; the bracket 14 is used to place and support the electromechanical air conditioning pipes; the outer fixing ring 20 is fixed to the bottom of the inner side of the protective shell 12 to provide a fixed foundation for the buffer structure; the inner fixing ring 21 is fitted on the upper mounting column 13 to transmit pipe vibration; the buffer components work together with the fixing components to achieve the shock absorption effect.
[0028] The buffer component also includes a fixing ring 221 fixed to the four sides of the inner ring of the fixing outer ring 20, and a memory spring 22 welded to the inner ring of the fixing ring 221. Both ends of the memory spring 22 are fixed with fixing rings 221.
[0029] The fixed ring 221 serves to connect the fixed outer ring 20 and the memory spring 22; the fixed inner ring 21 is driven by the pipe to swing back and forth in the memory spring 22, and the memory spring 22 absorbs the swing vibration by its own elasticity, reducing vibration transmission and achieving vibration reduction and noise reduction.
[0030] The buffer component also includes a limiting plate 23 sleeved on the outer ring of the bottom end of the upper fixed post 13, and one end of the fixing ring 221 is fixed in the center of the outer ring of the inner fixed ring 21.
[0031] The limiting plate 23 can limit the range of movement of the upper fixed column 13 and prevent it from moving excessively; at the same time, the fixing ring 221 further strengthens the connection between the memory spring 22 and the fixing inner ring 21, making the buffer structure more stable.
[0032] The buffer component also includes a hole 24 in the center of the upper end of the protective housing 12, the bottom end of the upper fixing post 13 passes through the hole 24, and the limiting plate 23 is larger than the area of the hole 24 and is located at the lower end of the hole 24.
[0033] The hole 24 at the upper end of the protective shell 12 provides a moving channel for the upper fixed post 13, which can slide up and down. The design of the limiting plate 23, which is larger than the area of the hole 24 and located at the lower end of the hole 24, can prevent the upper fixed post 13 from coming out of the hole 24 and ensure structural safety.
[0034] Working principle: When the pipeline vibrates, the vibration is first transmitted to the bracket 14 that directly supports the pipeline, causing the bracket 14 to sway left and right. The bracket 14 transmits the vibration to the upper fixed column 13 that is screwed to it, causing the upper fixed column 13 to prepare to move. Since the upper fixed column 13 is fixed to the inner fixed ring 21, the inner fixed ring 21 moves synchronously with the upper fixed column 13, thereby pulling or compressing the memory spring 22. The memory spring 22 absorbs the vibration energy through its own deformation, weakening the vibration intensity. After being buffered by the memory spring 22, the remaining small vibration is transmitted to the protective shell 12, the lower fixed column 11, and finally to the fixed base 10 fixed to the ground. At this time, the vibration has been greatly weakened and cannot cause significant vibration of the building structure, thus protecting the structure. During the process, the hole 24 at the upper end of the protective shell 12 provides a moving channel for the upper fixed column 13. The limiting plate 23 restricts the movement range of the upper fixed column 13 to prevent it from falling out. The fixed ring 221 keeps the memory spring 22 firmly connected to other components, ensuring the stable operation of the entire process and ultimately achieving vibration reduction and noise reduction.
[0035] This solution addresses the problem of lateral swaying of the pipes on the connecting support components, which leads to loose bolt connections and loss of support by incorporating a buffer component.
[0036] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:
[0037] The disassembly components, including the quick-disassembly components, include a slot 30 in the center of the upper end of the bracket 14, a mounting slot 31 in the center of both ends of the slot 30, a torsion spring 32 welded to both ends inside the mounting slot 31, and a shaped claw 33 welded to the center of the two torsion springs 32.
[0038] The slot 30 is used to provide positioning space for the pipeline; the mounting slot 31 provides installation position for the torsion spring 32 and the irregular claw 33; the torsion spring 32 can drive the irregular claw 33 to reset, so that the claw keeps the pipeline clamped; the irregular claw 33 can firmly clamp the pipeline in the slot 30 by interlacing, preventing the pipeline from loosening.
[0039] The quick-release components also include an insertion interface 34 on one side of the upper end of the irregular claw 33, and a rubber plug 35 inserted into the insertion interface;
[0040] The insertion interface 34 on the irregular claw 33 is used to insert the fixing rod 36 and the rubber plug 35; the rubber plug 35 is inserted into the insertion interface 34 to prevent dust and impurities from entering the insertion interface 34 and to protect the insertion interface 34.
[0041] The quick-release component also includes a fixing rod 36 inserted into the insertion interface 34, with the irregularly shaped claws 33 in a staggered state, and the two ends of the fixing rod 36 inserted into the two insertion interfaces 34 respectively.
[0042] The fixing rod 36 is inserted into the insertion interface 34 of the two irregularly shaped claws 33, which can fix the interlaced irregularly shaped claws 33, enhance the clamping effect on the pipe, and prevent the claws from loosening during vibration and causing the pipe to fall off.
[0043] Working principle: First, the air conditioning pipe is placed in the slot 30 at the center of the upper end of the bracket 14. The slot 30 provides positioning for the pipe and prevents it from shifting during placement. In its natural state, the torsion spring 32 in the mounting groove 31 drives the two irregular claws 33 to reset due to its own elasticity. This causes the intersecting irregular claws 33 to clamp towards the pipe, initially fixing the pipe in the slot 30 and preventing it from loosening. Finally, the two ends of the fixing rod 36 are inserted into the insertion interface 34 at the upper end of the two irregular claws 33. The fixing rod 36 locks the intersecting irregular claws 33, further enhancing the clamping effect and preventing the claws from loosening and falling off due to pipe vibration.
[0044] This solution addresses the efficiency issue of needing to remove bolts during pipeline maintenance by incorporating quick-release components.
