Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, and in particular to a limiting structure for the bends of irregularly shaped air conditioning pipelines. Background Technology

[0002] In air conditioning systems, the installation and fixing of irregularly shaped pipes is a key link to ensure the normal operation of the system. Especially at pipe bends, due to stress concentration, vibration and other factors, problems such as deformation, cracking or displacement are prone to occur, which will affect the refrigerant flow efficiency and even cause system failure. The design of the limiting structure is crucial to ensuring the stability and reliability of the pipes.

[0003] Existing air conditioning pipe bend limiting structures are relatively simple, with poor adaptability to different pipe diameters and bending angles, making it difficult to meet the needs of diverse installation scenarios. The installation process is complicated, and pipe vibration during air conditioning operation and displacement caused by thermal expansion and contraction can easily lead to pipe fatigue and breakage, reducing the stability and service life of the air conditioning system.

[0004] Therefore, in response to the problems of poor adaptability, complicated installation process, and low stability of the existing limiting structure for the bends of irregular-shaped pipes used in air conditioning, a limiting structure for the bends of irregular-shaped pipes used in air conditioning can be designed. Summary of the Invention

[0005] In order to overcome the problems of poor adaptability of the limiting structure at the bend of the existing irregular-shaped air conditioning pipes, complicated installation process and low stability.

[0006] The technical solution of this utility model is as follows: a limiting structure for the bend of an irregularly shaped pipe for air conditioning, including an installation plate; it also includes a clamping plate and a rubber support ring. The upper end of the installation plate is rotatably connected to two limiting frames via a damping shaft. The upper end of the limiting frames is rotatably connected to two fixing clamps via a shaft. The inner walls of both the limiting frames and the fixing clamps are fixedly connected to clamping springs. The other end of each clamping spring is fixedly connected to a clamping plate. An adjusting rod is rotatably connected between the two limiting frames via a connecting seat. The upper end of the installation plate is slidably connected to a support seat. The inner wall of the support seat is fixedly connected to a compression spring. The other end of the compression spring is fixedly connected to a rubber support ring.

[0007] Preferably, the length of the adjusting rod is adjusted according to the bending angle of the pipeline, so that the two limiting brackets rotate around the damping shaft to the target angle. The pipeline is placed on the limiting brackets, and the sliding support seat is moved to the bending point of the pipeline. The rubber support ring is tightly fitted to the pipeline under the action of the compression spring. The fixed clamp is rotated to close, and the clamping plate clamps and fixes the two ends of the pipeline under the elastic force of the clamping spring. The clamping spring and the compression spring are adaptively adjusted to effectively reduce pipeline vibration.

[0008] Preferably, the surface of the mounting plate is provided with a limiting groove, the lower end of the limiting frame is slidably connected along the limiting groove, and the fixing clamp is threadedly connected to the limiting frame by fixing bolts.

[0009] Preferably, each clamping spring has a telescopic rod fitted inside it. One end of the telescopic rod is fixedly connected to the clamping plate, and the other end of the telescopic rod is fixedly connected to the corresponding fixing clamp and the limiting frame, respectively.

[0010] Preferably, there are three clamping plates arranged in a ring array, and the inner wall of the clamping plates is fixedly connected with rubber anti-slip pads, and the clamping surface of the rubber anti-slip pads is uniformly provided with anti-slip protrusions.

[0011] Preferably, the adjusting rod consists of a round rod and a threaded rod. One end of the round rod is threadedly connected to the threaded rod, and the ends of the round rod and the threaded rod that are far apart from each other are rotatably connected to the connecting seat. The other end of the connecting seat is rotatably connected to the limiting frame through a rotating shaft.

[0012] Preferably, the surface of the mounting plate is provided with an annular groove that is adapted to the lower end of the support.

[0013] Preferably, the compression springs are arranged in three groups at equal intervals, with two compression springs in each group, and the rubber support rings are designed with an arc shape, with three rubber support rings in total.

[0014] The beneficial effects of this utility model are:

[0015] This air conditioning pipe bend limiting structure uses clamping plates and rubber support rings. The length of the adjusting rod is adjusted according to the pipe's bend angle, allowing the two limiting brackets to rotate around the damping shaft to the target angle for precise adjustment. It adapts to pipes with multiple bend angles. The pipe is placed on the limiting brackets, and the sliding support seat is moved to the bend. The rubber support ring, under the action of the compression spring, fits tightly against the pipe, providing axial support. Rotating to close the fixing clamp, the clamping plate, under the elastic force of the clamping spring, clamps and fixes both ends of the pipe, keeping it relatively centered. It adapts to pipes of different diameters, offering high flexibility. The clamping and compression springs are self-adjusting, effectively reducing pipe vibration and preventing displacement due to thermal expansion and contraction, thus improving stability. The overall operation is simple, disassembly and maintenance are convenient, and it is reusable, reducing operating costs. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a limiting structure for the bends of irregularly shaped air conditioning pipes, including an installation plate 1; it also includes a clamping plate 5 and a rubber support ring 10. The upper end of the installation plate 1 is rotatably connected to two limiting frames 2 via a damping shaft. The upper end of each limiting frame 2 is rotatably connected to two fixing clamps 3 via a shaft. Clamping springs 4 are fixedly connected to the inner walls of both the limiting frames 2 and the fixing clamps 3. The other end of each clamping spring 4 is fixedly connected to a clamping plate 5. An adjusting rod 7 is rotatably connected between the two limiting frames 2 via a connecting seat 6. A support seat 8 is slidably connected to the upper end of the installation plate 1. A compression spring 9 is fixedly connected to the inner wall of the support seat 8. The other end of the compression spring 9 is fixedly connected to a rubber support ring 10. During use, the limiting structure adjusts according to the bend of the pipe. Adjust the length of the adjusting rod 7 to rotate the two limit brackets 2 around the damping shaft to the target angle for precise adjustment, adapting to pipelines with multiple angles. Place the pipeline on the limit bracket 2, slide the support seat 8 to the bend of the pipeline, and the rubber support ring 10 fits tightly with the pipeline under the action of the compression spring 9, providing axial support. Rotate to close the fixing clamp 3, and the clamping plate 5 clamps and fixes both ends of the pipeline under the elastic force of the clamping spring 4, making the pipeline relatively centered. It is suitable for pipelines of different diameters, with high flexibility. The clamping spring 4 and the compression spring 9 are self-adjusting, effectively reducing pipeline vibration, avoiding displacement caused by thermal expansion and contraction, improving stability. The overall operation is simple, disassembly and maintenance are convenient, and it can be reused, reducing the cost of use.

[0024] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, a limiting groove 11 is formed on the surface of the mounting plate 1. The lower end of the limiting frame 2 is slidably connected along the limiting groove 11. The fixing clamps 3 are threadedly connected to the limiting frame 2 by fixing bolts 12. Angle scale lines can be set on the outside of the limiting groove 11. The lower end of the limiting frame 2 slides precisely along the limiting groove 11. Rotating the fixing bolts 12 realizes the closure of the fixing clamps 3 and the limiting frame 2. The clamping springs 4 are all fitted with telescopic rods 13. One end of the telescopic rod 13 is fixedly connected to the clamping plate 5. The other end of the telescopic rod 13... One end is fixedly connected to the corresponding fixing clamp 3 and limiting frame 2 respectively. The telescopic rod 13 controls the movement path of the clamping spring 4, provides radial elastic force, adapts to different pipe diameters, and increases clamping force. There are three clamping plates 5 arranged in a ring array. The inner wall of the clamping plate 5 is fixedly connected to a rubber anti-slip pad 14. The clamping surface of the rubber anti-slip pad 14 is evenly provided with anti-slip protrusions. The clamping plates 5 arranged in a ring array make the pipe relatively centered. The anti-slip protrusions enhance the limiting of the rubber anti-slip pad 14 on the pipe and improve stability.

[0025] Please see Figure 1 , Figure 4 and Figure 5 In this embodiment, the adjusting rod 7 is composed of a round rod 701 and a threaded rod 702. One end of the round rod 701 is threadedly connected to the threaded rod 702. The ends of the round rod 701 and the threaded rod 702 that are far apart from each other are rotatably connected to the connecting seat 6. The other end of the connecting seat 6 is rotatably connected to the limiting frame 2 through a rotating shaft. Rotating the threaded rod 702 adjusts the length of the round rod 701, and precisely adjusts the included angle between the two limiting frames 2 to adapt to different pipe bending angles. The surface of the mounting plate 1 is provided with an annular groove 15. The annular groove 15 is adapted to the lower end of the support seat 8. The support seat 8 slides along the annular groove 15 to accommodate pipes with different included angles. Three sets of compression springs 9 are arranged at equal intervals, and each set of compression springs 9 has two springs. The rubber support rings 10 have an arc-shaped structure design, and three rubber support rings 10 are provided. The three sets of compression springs 9 provide stable axial support force and absorb the axial vibration of the pipe.

[0026] During operation, the length of the threaded rod 702 and the round rod 701 are adjusted according to the bending angle of the pipeline, so that the two limiting brackets 2 rotate around the damping shaft to the target angle. The pipeline is then placed on the limiting brackets 2, and the support seat 8 slides along the annular groove 15 to the bending point of the pipeline. The rubber support ring 10 fits tightly with the pipeline under the action of the compression spring 9, providing axial support. Rotating the fixing bolt 12 closes the fixing clamp 3 and the limiting bracket 2. The clamping plate 5 clamps and fixes the two ends of the pipeline under the elastic force of the clamping spring 4, making the pipeline relatively centered and adaptable to pipelines of different diameters. The clamping spring 4 and the compression spring 9 self-adjust, effectively reducing pipeline vibration, avoiding displacement caused by thermal expansion and contraction, improving stability. The overall operation is simple, disassembly and maintenance are convenient, and it can be reused, reducing the cost of use.

[0027] Through the above steps, the rubber support ring 10 fits tightly with the pipeline under the action of the compression spring 9, and the clamping plate 5 clamps and fixes both ends of the pipeline under the elastic force of the clamping spring 4. It adapts to different pipelines, and the clamping spring 4 and the compression spring 9 self-adjust, which improves stability and makes disassembly and maintenance convenient. This solves the problems of poor adaptability of the limiting structure at the bend of the existing irregular-shaped pipeline for air conditioning, complicated installation process and low stability.
