Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a connection structure, a pipeline structure and an air conditioner. Background Art

[0002] During operation, the compressor inside an air conditioner's outdoor unit vibrates due to its internal structure, which in turn causes vibration in the connected piping. This can further cause excessive stress and strain in the piping, and can even lead to fatigue fracture within a short period of time, shortening the unit's service life. Rubber hose fixing blocks are widely used in air conditioners, often for pipe vibration reduction.

[0025] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0026] According to an embodiment of the present invention, a connection structure is provided. Figures 1 to 3 , including: a connecting body 1, a first mounting hole 11 and a second mounting hole 12 are provided on the connecting body 1, and the first mounting hole 11 and the second mounting hole 12 are arranged at intervals; the first mounting hole 11 and the second mounting hole 12 both penetrate the connecting body 1; a first supporting portion 2 is arranged in the connecting body 1, and the first supporting portion 2 and the inner wall surface of the first mounting hole 11 are arranged parallel to each other; a second supporting portion 3 is arranged in the connecting body 1, and the second supporting portion 3 and the inner wall surface of the second mounting hole 12 are arranged parallel to each other; a connecting component 4, the connecting component 4 is connected to the side of the first supporting portion 2 away from the first mounting hole 11; the connecting component 4 is connected to the side of the second supporting portion 3 away from the second mounting hole 12.

[0027] In the connection structure of this embodiment, a first support portion 2 and a second support portion 3 are provided in the connection body 1, and the first support portion 2 and the second support portion 3 are connected by a connection assembly 4, so that the overall structure of the connection structure is more stable and firm. When in use, the branch pipe is passed through the first mounting hole 11 and the second mounting hole 12, respectively, and then supported by the first support portion 2 and the second support portion 3, and the outermost portion is fixed by the connection body 1. In this way, when the connected equipment vibrates, the connection structure can reduce the vibration displacement of the branch pipe, that is, reduce the tangential position offset of the branch pipe, thereby reducing the stress of the branch pipe caused by vibration. The connection structure of the present invention solves the technical problem in the related art that the ordinary pipe connection structure has weak constraints in the tangential direction and is easily stimulated by the equipment to resonate, resulting in excessive strain.

[0028] Specifically, a connecting assembly 4 is provided between the first supporting portion 2 and the second supporting portion 3 to support the first supporting portion 2 and the second supporting portion 3. The connecting assembly 4 is connected to the side of the first supporting portion 2 away from the first mounting hole 11; the connecting assembly 4 is connected to the side of the second supporting portion 3 away from the second mounting hole 12, thereby hindering the relative movement of the first supporting portion 2 and the second supporting portion 3. When the above structure is further provided in the connecting body 1, the relative movement between the first mounting hole 11 and the second mounting hole 12 can be hindered. This thereby restricts the relative movement of the pipelines respectively installed in the first mounting hole 11 and the second mounting hole 12 in the tangential direction.

[0029] Specifically, the connection body 1 is made of rubber; the first support portion 2 and the second support portion 3 are made of steel sheets.

[0030] See Figure 2 and Figure 3 In the connection structure of this embodiment, the connection assembly 4 includes: a first connection portion 41, one end of which is connected to the first support portion 2 and the other end of which is connected to the second support portion 3; and a second connection portion 42, spaced apart from the first connection portion 41; one end of the second connection portion 42 is connected to the first support portion 2 and the other end of the second connection portion 42 is connected to the second support portion 3. Using this connection structure, the first support portion 2 and the second support portion 3 are respectively connected to the first connection portion 41 and the second connection portion 42 at the ends of the connection assembly 4, thereby achieving a more stable and secure connection of multiple components.

[0031] See Figure 2 and Figure 3In the connection structure of this embodiment, the connection assembly 4 further includes a fixing plate 43, one end of which is connected to the first connection portion 41, and the other end of which is connected to the second connection portion 42. The provision of the fixing plate 43 can increase the stability between the first connection portion 41 and the second connection portion 42, prevent the first support portion 2 and the second support portion 3 from being misaligned or deformed, and improve the firmness of the entire connection structure.

[0032] See Figure 2 and Figure 3 In the connection structure of this embodiment, the first mounting hole 11 is a circular through-hole, and the second mounting hole 12 is a circular through-hole. The connection structure has a predetermined plane 5, with the axes of the first mounting hole 11 and the second mounting hole 12 both lying on the predetermined plane 5. A predetermined angle is formed between the fixing plate 43 and the predetermined plane 5, with the predetermined angle ranging from 30° to 150°. The circular through-holes are designed to accommodate the branch pipe being sleeved, ensuring a close structural fit between the two and thereby increasing the stability of the sleeved branch pipe. The predetermined angle of 30° to 150° between the fixing plate 43 and the predetermined plane 5 limits the installation position of the fixing plate 43, indirectly restricting the two embedded support portions from vibrating and preventing resonance, thereby increasing the tangential restraint force of the connection structure.

[0033] See Figure 2 and Figure 3 In the connection structure of this embodiment, the first support portion 2 has a first connection end 21 connected to the first connection portion 41, and a second connection end 22 connected to the second connection portion 42. The first mounting hole 11 is located between the first connection end 21 and the second connection end 22. Because the first mounting hole 11 is located between the first connection end 21 and the second connection end 22, when the pipeline enters the first mounting hole 11, the pipeline is also fixedly connected between the first connection end 21 and the second connection end 22 by the first support portion 2. This expands the support area of ​​the first support portion 2 for the first mounting hole 11 and improves the firmness of the pipeline.

[0034] In some embodiments of the connection structure, the second support portion 3 has a third connection end 31 connected to the first connection portion 41, and the second support portion 3 has a fourth connection end 32 connected to the second connection portion 42. The second mounting hole 12 is located between the third connection end 31 and the fourth connection end 32. After the pipeline enters the second mounting hole 12, the pipeline is correspondingly fixed between the third connection end 31 and the fourth connection end 32 by the second support portion 3. This expands the support area of ​​the second support portion 3 for the second mounting hole 12 and improves the firmness of the pipeline.

[0035] See Figure 1 and Figure 2In the connection structure of this embodiment, the first mounting hole 11 is a circular through-hole, and the first support portion 2 is an annular structure. The inner diameter of the first mounting hole 11 is smaller than the inner diameter of the first support portion 2. The circular shape of the first mounting hole 11 and the annular structure of the first support portion 2 improve the compatibility between the two. In addition, the smaller inner diameter of the first mounting hole 11 than the inner diameter of the first support portion 2 ensures that, after the pipeline enters the first mounting hole 11, it is clamped by the ends of the annular first support portion 2, achieving a clamping effect on the pipeline and improving the stability of the first mounting hole 11 on the pipeline.

[0036] In some embodiments of the connection structure, second mounting hole 12 is a circular through-hole, second support portion 3 is an annular structure, and the inner diameter of second mounting hole 12 is smaller than the inner diameter of second support portion 3. When the pipeline enters second mounting hole 12, a clamping force is generated at both ends of the annular second support portion 3, thereby clamping the pipeline and improving the stability of second mounting hole 12 on the pipeline.

[0037] See Figure 1 In this embodiment, the connection structure has a predetermined plane 5, and is symmetrical about the predetermined plane 5. The first support portion 2 is also symmetrical about the predetermined plane 5, and the second support portion 3 is also symmetrical about the predetermined plane 5. These symmetrical structures ensure that when the device vibrates, the forces on each plane are balanced, and thus the restraining forces are also balanced.

[0038] See Figure 1 and Figure 3 In the connection structure of this embodiment, the connection body 1 includes: a first slot 13, one end of which is connected to the first mounting hole 11, and the other end of the first slot 13 is connected to the outside of the connection body 1; a second slot 14, one end of which is connected to the second mounting hole 12, and the other end of the second slot 14 is connected to the outside of the connection body 1; wherein, the first slot 13 and the second slot 14 are both symmetrical structures along the extension direction with the preset plane 5 as the symmetry plane. When the equipment vibrates, it will excite the vibration of the pipeline system. The pipelines directly connected to the equipment, such as the exhaust pipe and the intake pipe, will be most excited. When the equipment frequency approaches the natural frequency of these pipelines, it will cause resonance. At this time, the vibration is most intense, and the branches on these pipelines will also vibrate accordingly. Slots are set at the corresponding positions of the two mounting holes, and one end of the slot is connected to the outside of the connection body 1, which facilitates the installation of the connection structure on the pipeline and realizes connection with the pipeline. The first slot 13 , the second slot 14 , the first support portion 2 , the second support portion 3 and the connecting assembly 4 are all symmetrical structures with the preset plane 5 as the symmetry plane, which increases the overall firmness of the connecting structure.

[0039] See also Figure 3The piping structure of this embodiment includes: a connecting structure, which may be any of the connecting structures described above; a first pipe 6, which is inserted into a first mounting hole 11 of the connecting structure; and a second pipe 7, which is inserted into a second mounting hole 12 of the connecting structure. When the equipment vibrates, these pipes will vibrate accordingly. The connecting structure secures these pipes, suppressing not only their longitudinal vibration but also their tangential vibration, thereby reducing stress at the bends of the branch pipes.

[0040] The air conditioner of this embodiment includes the aforementioned piping structure. The piping structure is used on the piping of the air conditioner's outdoor unit. Since the compressor of the air conditioner's outdoor unit causes vibration in the connected piping during operation, the connecting structure can be used to secure the piping in all directions, suppressing vibration of the branch pipes and thereby reducing the stress caused by vibration.

[0041] The main body of the above-mentioned connection structure is composed of an ordinary rubber tube and a steel sheet. A steel sheet of a specific shape is embedded inside the rubber tube connection body 1 as the first support part 2, the second support part 3 and the connection component 4. The steel sheet is welded from two arc-shaped steel sheets and three rectangular steel sheets. The function of the fixing plate 43 is to enhance the rigidity of the entire steel sheet structure. Both the arc-shaped steel sheet and the rectangular steel sheet are uniform thin shell structures, located between the two pipe openings of the connection structure. Their height is less than the thickness of the connection structure and is between 0.2 times and 1 times the thickness of the connection body 1. The arc-shaped steel sheet is concentric with the pipe opening, and its diameter is slightly larger than the pipe opening diameter. The angle between the fixing plate 43 and the line connecting the centers of the two pipe openings is between 30° and 150°.
