[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0040] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] like Figure 1-Figure 4 As shown, this embodiment provides a vibration damping block for pipelines, which includes a vibration damping block body 100, on which positioning grooves are arranged, as well as two opposite first side surfaces 101 and two second side surfaces 102, wherein the positioning grooves include a pair of first positioning grooves 110, a pair of second positioning grooves 120 and a pair of third positioning grooves 130, wherein the first positioning grooves 110 and the second positioning grooves 120 are connected and cross-connected on the first side surface 101, and the third positioning groove 130 is connected and connected on the second side surface 102, and the spacings between the pair of first positioning grooves 110, the pair of second positioning grooves 120 and the pair of third positioning grooves 130 are all different.

[0042] Positioning grooves are provided on the vibration-damping block body 100 to accommodate the pipeline to be damped, so as to achieve the vibration-damping effect on the pipeline to be damped and reduce the damage and noise caused by vibration of the pipeline. Specifically, the positioning grooves include three pairs, wherein a pair of first positioning grooves 110 and a pair of second positioning grooves 120 are respectively corresponding to and cross-set on two opposite first side surfaces 101 of the vibration-damping block body 100, and another pair of third positioning grooves 130 are respectively corresponding to and cross-set on two opposite second side surfaces 102 of the vibration-damping block body 100, and the spacing between the groove bottoms of each pair of positioning grooves is different, that is, the extension direction and spacing distance of each pair of positioning grooves are different, so as to adapt to pipelines to be damped with different directions and pipelines to be damped with different spacing distances, so that the same pipeline vibration-damping block can be applied to different positions, reducing the types of vibration-damping blocks, effectively reducing material management costs, and facilitating the standardization of materials.

[0043] This embodiment also discloses an air source heat pump, comprising at least two groups of pipelines to be damped and connected to the pipeline damping blocks described in any of the above schemes, and each group of pipelines to be damped can be connected to one of the pairs of positioning grooves of a pipeline damping block described in any of the above schemes. By adopting the above pipeline damping blocks, the air source heat pump can be applied to pipelines to be damped at different intervals, reducing the steps of selection and adaptation during the installation process and improving the convenience of installation. At the same time, the types of damping blocks are reduced, the material management cost is reduced, and the degree of material standardization is improved.

[0044] Exemplarily, the air source heat pump includes a low-pressure switch pipeline 310, a return pipe 320, a liquid distributor pipeline 330, a gas collecting pipe 340, an exhaust pipeline 350 and a high-pressure switch pipeline 360. The exhaust pipeline 350 and the high-pressure switch pipeline 360 ​​are used to reduce vibration by cooperating with the third positioning groove 130; the liquid distributor pipeline 330 and the gas collecting pipe 340 are used to reduce vibration by cooperating with the second positioning groove 120; and the low-pressure switch pipeline 310 and the return pipe 320 are used to reduce vibration by cooperating with the first positioning groove 110.

[0045] Furthermore, the cross-section of the positioning groove is set to an arc shape to adapt to the outer diameter of the pipeline to be damped; the curvature of the two positioning grooves in at least one pair is different to adapt to the vibration reduction between two pipelines to be damped with different outer diameters, or the curvature of the two positioning grooves in a pair can be the same to adapt to the vibration reduction between two pipelines to be damped with the same outer diameter. Technical personnel in this field can make settings as needed and no specific limitation is made here.

[0046] In this embodiment, the positioning grooves are all centrally arranged on the corresponding surfaces of the vibration damping block body 100, so that the vibration damping block body 100 is more balanced when clamped with the pipeline to be damped. It is worth noting that the first positioning groove 110 and the second positioning groove 120 are both centrally arranged, so that the second positioning groove 120 can divide the first positioning groove 110 into two parts, and the two parts are respectively located on both sides of the second positioning groove 120, which is conducive to improving the reliability of the cooperation between the first positioning groove 110 and the pipeline to be damped that cooperates with it.

[0047] Preferably, the pipeline vibration damping block also includes a cable tie, which can be wrapped around the outside of the vibration damping block body 100. The cable tie can be used to fix the pipeline to be damped to the vibration damping block body 100, thereby improving the firmness of the vibration damping block body 100 installed on the pipeline to be damped, thereby ensuring the vibration damping effect.

[0048] In other embodiments, Figure 5-Figure 9 As shown, the pipeline vibration damping block also includes a fixing component, which is fixedly connected to the vibration damping block body 100 and is used to fix the pipeline to be damped and the vibration damping block body 100. It can be understood that by setting the fixing component, the fixing operation between the vibration damping block body 100 and the pipeline to be damped is more convenient, and no additional cable ties need to be prepared, which further simplifies material management. Optionally, the fixing component can be set to be integrally set with the vibration damping block body 100.

[0049] In this embodiment, the fixing assembly includes a first fixing assembly 201 and a second fixing assembly 202. The first fixing assembly 201 is used to fix the pipeline to be damped to the first positioning groove 110 or the second positioning groove 120, and the second fixing assembly 202 is used to fix the pipeline to be damped to the third positioning groove 130. By setting different fixing assemblies corresponding to the installation between different positioning grooves and the pipeline to be damped, the installation is more reliable. Since the first positioning groove 110 and the second positioning groove 120 are both set on the first side 101, only the first fixing assembly 201 is set, which is conducive to simplifying the structure.

[0050] Optionally, the pipeline vibration damping block further includes a third side surface 103, which is perpendicular to the first side surface 101 and the second side surface 102. The pipeline vibration damping block is arranged in a square shape, and the two third side surfaces 103 are respectively the front and back sides of the pipeline vibration damping block, and the two first side surfaces 101 and the second side surfaces 102 are the four sides of the pipeline vibration damping block. The first fixing component 201 and the second fixing component 202 are arranged on the third side surface 103 of the vibration damping block body 100. Since the third side surface 103 is not provided with a positioning groove, it will not cause interference with the fixing component.

[0051] Specifically, the first fixing assembly 201 includes two first fixing straps 211 and two first fixing buckles 221, and the two first fixing straps 211 and the two first fixing buckles 221 are all arranged on the same third side surface 103. The first fixing straps 211 are arranged perpendicularly to the first positioning groove 110 and the second positioning groove 120, and each first fixing strap 211 can be connected to any first fixing buckle 221. When in use, Figure 8 As shown, when the first fixing assembly 201 is used to fix the pipeline to be damped placed in the second positioning groove 120, the two first fixing belts 211 can be crossed and wound around a positioning groove and connected with the two first fixing buckles 221; Fig. 9 As shown, when the first fixing assembly 201 is used to fix the pipeline to be damped placed in the first positioning groove 110 , the two first fixing belts 211 can be arranged in parallel around one positioning groove and connected to the two first fixing buckles 221 .

[0052] Furthermore, the second fixing assembly 202 includes a second fixing belt 212 and a second fixing buckle 222. The second fixing belt 212 and the second fixing buckle 222 are both arranged on the same third side surface 103. The second fixing belt 212 is perpendicular to the third positioning groove 130 and is arranged parallel to the third side surface 103. Figure 7 As shown, when the second fixing assembly 202 is used to fix the pipeline to be damped placed in the third positioning groove 130 , the second fixing belt 212 is wrapped around the pipeline to be damped and then fixed with the second fixing buckle 222 .

[0053] It is worth noting that a plurality of anti-slip teeth 211 are provided at the movable end of the second fixing belt 212, and a clamping hole 221 is correspondingly provided at the second fixing buckle 222. The second fixing belt 212 can be inserted into the clamping hole 221, and at least one anti-slip tooth 211 can be clamped and abutted against one end of the clamping hole 221, so that the second fixing belt 212 is connected to the second fixing buckle 222. By providing the anti-slip teeth 211, it is possible to effectively prevent the second fixing belt 212 and the second fixing buckle 222 from falling off after being connected; by providing a plurality of anti-slip teeth 211, the versatility of the vibration damping block for pipelines can be improved. The specific structure of the first fixing belt 211 and the first fixing buckle 221 refers to the second fixing belt 212 and the second fixing buckle 222, and will not be repeated here.

[0054] Furthermore, the anti-slip tooth 211 includes a guide surface and a clamping surface. The guide surface is used to guide the clamping belt when it is passed through the clamping hole 221, and the clamping surface is used to abut against the end surface of the clamping hole 221.

[0055] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The specific contents of the above specific implementations only express several implementations of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
