DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0026] Nowadays, the functions of air conditioners are more and more diversified, and the components connected to the pipeline of the air conditioner are also increasing. In the prior art, in order to avoid the situation that the vibration displacement of the pipeline and the component is inconsistent, causing the connection between the pipeline and the component to break, two rubber pipe fixing blocks are generally fixed on the component and high-temperature wire is used for binding, so that the pipeline and the component remain in a relatively static state. However, the fixing method of the fixing block and the binding has very limited effect on the relative vibration, and the fixing block is easy to rotate around the pipeline and is also easy to displace in the direction perpendicular to the plane formed by the pipeline and the component, thereby causing the pipeline and the component to leak at the connection.

[0027] Therefore, in order to solve the technical problem that the pipeline and the component are easy to break at the connection due to inconsistent vibration displacement in the prior art, the present application provides a damping connection structure, comprising:

[0028] The bracket assembly is fixedly connected with the pipeline, and the bracket assembly is used for fixing the detection piece connected with the pipeline;

[0029] The damping assembly is arranged on the bracket assembly and absorbs the vibration energy of the pipeline, and the self-vibration frequency of the damping assembly is adjustable.

[0030] As can be seen, the detection component connected to the pipeline is fixed in place by a bracket assembly, which is also equipped with a vibration damping assembly to absorb the pipeline's vibration energy. Therefore, the vibration damping assembly can reduce the pipeline's vibration amplitude, preventing excessive pipeline vibration amplitude from causing fracture at the connection between the pipeline and the detection component. In addition, the vibration damping assembly's natural frequency is adjustable. Therefore, when the natural frequency of the pipeline vibration changes, the vibration damping assembly can adjust its own natural frequency accordingly, minimizing the vibration amplitude of the entire vibration damping connection structure and the pipeline, preventing large relative displacement between the pipeline and the detection component that could cause fracture at the connection.

[0031] Furthermore, in order to prevent the detection member and the vibration reduction assembly from being positioned unbalanced on the bracket assembly, which would cause the detection member to vibrate due to the imbalance, the vibration reduction assembly and the detection member are respectively located on both sides of the pipeline.

[0032] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0033] like Figure 1 As shown, in this embodiment, the vibration-damping connection structure includes: a bracket assembly, which is fixedly connected to the pipeline, and the bracket assembly is used to fix the detection part connected to the pipeline; a vibration-damping assembly, which is arranged on the bracket assembly to absorb the vibration energy of the pipeline, and the natural frequency of the vibration-damping assembly is adjustable, wherein the vibration-damping assembly and the detection part are respectively located on both sides of the pipeline.

[0034] Specifically, such as Figures 2 to 4 As shown, the bracket assembly includes: a first clamping plate 1 and a second clamping plate 2, which are arranged to clamp the detection part 4 and the pipeline 3. The first clamping plate 1 and the second clamping plate 2 are mirror-image structures, wherein the surfaces of the first clamping plate 1 and the second clamping plate 2 that are in contact with each other are provided with a detection part placement groove 6. When the first clamping plate and the second clamping plate are in contact with each other, the two detection part placement grooves are combined into a whole, and the structure of the whole is the same as the shape and size of the detection part. Similarly, the surfaces of the first clamping plate 1 and the second clamping plate 2 that are in contact with each other are provided with a pipeline placement groove 5. When the first clamping plate and the second clamping plate are in contact with each other, the two pipeline placement grooves are combined into a whole, and the structure of the whole is the same as the shape and size of the pipeline. The shape and size of the detection part placement groove are set to be exactly the same as the shape and size of the detection part, which can effectively prevent the detection part from vibrating in other directions, and more conveniently ensure that the vibration displacement of the detection part and the pipeline is consistent. The shape and size of the pipeline placement groove are set to be exactly the same as the shape and size of the pipeline, which can effectively prevent the bracket assembly from vibrating in other directions, and more conveniently ensure that the vibration displacement of the detection part and the pipeline is consistent. In addition, the first clamping plate 1 and the second clamping plate 2 are respectively provided with a clearance gap 7 of the same size and corresponding position, the vibration reduction component is arranged in the clearance gap, and the pipeline placement groove 5 is located between the clearance gap 7 and the detection component placement groove 6.

[0035] Specifically, such as Figure 1 andFigure 5 As shown in the embodiment, the damping assembly comprises a counterweight 8, a connecting piece 9 connected to the counterweight 8 at one end, and the other end of the connecting piece 9 is fixedly connected with the support assembly, and the connecting position where the connecting piece is fixedly connected with the support assembly is provided with multiple positions, so that the distance between the connecting position and the counterweight is not fixed. When the distance between the connecting position and the counterweight is different, the length of the connecting piece swinging with the counterweight is also different, so that the natural frequency of the whole damping assembly will change. Specifically, the counterweight 8 is spherical, the connecting piece 9 is long strip-shaped, one end of the connecting piece 9 is fixedly welded with the counterweight 8, and multiple insertion holes 91 are provided on the other end of the connecting piece 9. The first clamping plate 1 and the second clamping plate 2 are respectively provided with size-consistent and position-corresponding accommodation notches 7, the counterweight 8 and the connecting piece 9 are arranged in the accommodation notches 7, wherein the second clamping plate 2 is provided with a connecting piece placement groove 21 for placing the connecting piece, the connecting piece placement groove 21 is communicated with the accommodation notches 7, and the second clamping plate 2 is further provided with an insertion column 22 inserted with the insertion holes 91. When different insertion holes on the connecting piece are inserted with the insertion column, the length of the connecting piece extending out of the accommodation notch is different, so that the natural frequency of the connecting piece and the counterweight when swinging is different. Therefore, when the damping connection structure is arranged on the pipeline with different fixed frequencies, the natural frequency of the damping assembly can be calculated according to the fixed frequency of the pipeline, the specific parameters of the support assembly and the detection piece in advance, so that the whole damping connection structure can reach the resonance state with the pipeline, consume the system vibration energy, reduce the system vibration, and prevent the detection piece and the pipeline from being vibrated too much to cause the rupture of the connecting position.

[0036] Further, as shown in Figure 1 and Figure 4 the embodiment, the detection piece is a pressure sensor, and the detection piece placement groove 6 includes a first placement section 61, a second placement section 62, a third placement section 63, and a fourth placement section 64 according to the specific shape of the detection piece. The shape of the first placement section 61 after being combined with the first clamping plate 1 and the second clamping plate 2 is hexagonal prism-shaped, the shape of the second placement section 62 after being combined with the first clamping plate 1 and the second clamping plate 2 is cylindrical, the shape of the third placement section 63 after being combined with the first clamping plate 1 and the second clamping plate 2 is hexagonal prism-shaped, and the shape of the fourth placement section 64 after being combined with the first clamping plate 1 and the second clamping plate 2 is cubic. The fourth placement section 64 is provided with a positioning groove, and the detection piece is provided with a positioning protrusion correspondingly.

[0037] Further, in order to increase the stability of the whole damping connection structure and prevent the damping connection structure from vibrating in multiple directions, the first clamping plate 1 and the second clamping plate 2 are provided with reinforcing ribs 10 and reinforcing bosses 11, and the reinforcing ribs 10 and the reinforcing bosses 11 are arranged on the two sides of the pipeline 3 respectively.

[0038] The application also provides a pipeline system, which comprises a pipeline and the damping connection structure provided on the pipeline.

[0039] Specifically, as shown in Figure 1 The detection member 4 is connected to the pipeline 3, and the detection member 4 and the pipeline 3 are fixed in position by a support assembly. The support assembly includes a first clamping plate 1 and a second clamping plate 2 that embrace and clamp the detection member 4 and the pipeline 3. The first clamping plate and the second clamping plate are mirror image structures, and each of the first clamping plate 1 and the second clamping plate 2 is provided with a detection member placement groove 6 on the surface that abuts against the other. When the first clamping plate and the second clamping plate are abutted and fixed, the two detection member placement grooves form an integral whole, and the structure of the integral whole is the same as the shape and size of the detection member. Similarly, the first clamping plate 1 and the second clamping plate 2 are each provided with a pipeline placement groove 5 on the surface that abuts against the other. When the first clamping plate and the second clamping plate are abutted and fixed, the two pipeline placement grooves form an integral whole, and the structure of the integral whole is the same as the shape and size of the pipeline. The shape of the detection member placement groove is set to be exactly the same as the shape and size of the detection member, which can effectively avoid vibration displacement of the detection member in other directions, and more conveniently make the vibration displacement of the detection member and the pipeline consistent. The shape of the pipeline placement groove is set to be exactly the same as the shape and size of the pipeline, which can effectively avoid vibration displacement of the support assembly in other directions, and more conveniently make the vibration displacement of the detection member and the pipeline consistent. In addition, the first clamping plate and the second clamping plate are each provided with a size-consistent and position-corresponding gap, and a damping assembly is arranged in the gap. The pipeline placement groove is located between the gap and the detection member placement groove.

[0040] Specifically, as shown in Figure 1 and Figure 5As shown, in the embodiment, the damping assembly comprises a counterweight 8, a connecting piece 9 connected with the counterweight 8 at one end, and the other end of the connecting piece 9 is fixedly connected with the support assembly, and the connecting position where the connecting piece is fixedly connected with the support assembly is provided with multiple positions, so that the distance between the connecting position and the counterweight is not fixed. When the distance between the connecting position and the counterweight is different, the length of the connecting piece swinging with the counterweight is also different, so that the natural frequency of the whole damping assembly is also changed. Specifically, the counterweight 8 is spherical, the connecting piece 9 is strip-shaped, one end of the connecting piece 9 is fixedly welded with the counterweight 8, and multiple insertion holes 91 are provided on the other end of the connecting piece 9. The first clamping plate 1 and the second clamping plate 2 are respectively provided with the size-consistent and position-corresponding accommodation notches 7, the counterweight 8 and the connecting piece 9 are arranged in the accommodation notches, wherein the second clamping plate 2 is provided with a connecting piece placing groove 21 for placing the connecting piece, the connecting piece placing groove 21 is communicated with the accommodation notches 7, and the second clamping plate 2 is further provided with an insertion column 22 inserted with the insertion holes 91. When different insertion holes on the connecting piece are inserted with the insertion column, the length of the connecting piece extending out of the accommodation notches is different, so that the natural frequency of the connecting piece and the counterweight swinging is different. Therefore, when the damping connecting structure is arranged on the pipeline with different fixed frequencies, the natural frequency of the damping assembly can be calculated according to the fixed frequency of the pipeline, the specific parameters of the support assembly and the detection piece in advance, so that the whole damping connecting structure can reach the resonance state with the pipeline, consume the vibration energy of the system, reduce the vibration of the system, and prevent the vibration displacement between the pipeline and the detection piece from being too large to cause the rupture of the connecting position.

[0041] In conclusion, the damping assembly reduces the vibration amplitude of the pipeline, and avoids the rupture of the connecting position between the pipeline and the detection piece caused by the too large vibration amplitude of the pipeline. In addition, the natural frequency of the damping assembly is adjustable, so that when the natural frequency of the pipeline vibration changes, the damping assembly can adjust the natural frequency of itself, so that the vibration amplitude of the whole damping connecting structure and the pipeline is reduced, and the vibration displacement between the pipeline and the detection piece is prevented from being too large to cause the rupture of the connecting position.
