In another embodiment, the air conditioning device may be an outdoor unit, that is, the wind from the wind outlet blows to the outside.

In one embodiment, referring to fig. 1 and 2, a mounting groove 11b is formed at the top of the clamping body 11, the mounting groove 11b is communicated with the clamping tube hole 11a, and the pipe 30 can restorably prop the mounting groove 11b open to enter the clamping tube hole 11a or leave the clamping tube hole 11 a. That is to say, the width of the mounting groove 11b is small, the mounting groove 11b has elastic deformation capability, when the pipe fitting 30 needs to be clamped, a large acting force is applied to the pipe fitting 30, so that the pipe fitting 30 props open the mounting groove 11b to enter the clamping pipe hole 11a, the mounting groove 11b can be restored to an initial state, and thus, the pipe fitting 30 is prevented from being separated from the clamping pipe hole 11a under the condition of small acting force. When the pipe fitting 30 and the buckle 10 need to be disassembled, a large acting force is applied to the pipe fitting 30, so that the pipe fitting 30 props the installation groove 11b to be separated from the clamping pipe hole 11a, and the installation groove 11b can be restored to the initial state. In this way, quick assembly of the tube 30 and the buckle 10 is facilitated.

In one embodiment, referring to fig. 1 and 2, an end of the mounting groove 11b remote from the clamping tube hole 11a is enlarged to form a guide groove 11 b'. By the design, the width of the guide groove 11b 'is larger than that of the installation groove 11b, the alignment difficulty of the pipe fitting 30 and the installation groove 11b is reduced to a certain extent, and the pipe fitting 30 can quickly and smoothly enter the installation under the guidance of the guide groove 11 b'.

The specific shape of the guide groove 11b 'is not limited, and for example, in one embodiment, referring to fig. 1 and 2, the width of the guide groove 11 b' is gradually reduced from the top side of the holding body 11 to the bottom side of the holding body 11. That is, the guide groove 11 b' has a substantially funnel-shaped cross-sectional shape. When the pipe fitting 30 is installed, the peripheral side surface of the pipe fitting 30 is abutted to the chamfer surface of the guide groove 11 b', the notch of the installation groove 11b is gradually opened, and the pipe fitting 30 is clamped more conveniently and the installation resistance is smaller because the width of the chamfer surface is uniform.

In one embodiment, referring to fig. 1, 3 and 4, the buckle 10 includes a tightening strap 13, the clamping body 11 is formed with a through hole 11c at the bottom side of the clamping tube hole 11a, the through hole 11c extends in a direction perpendicular to the extending direction of the clamping tube hole 11a, and the tightening strap 13 can pass through the through hole 11c and surround the clamping body 11 to tighten the clamping tube hole 11 a. The extending direction of the clamp tube hole 11a is substantially the same as the extending direction of the pipe 30, and the extending direction of the through hole 11c is substantially the same as the radial direction of the pipe 30. After the pipe fitting 30 is clamped into the clamping tube hole 11a, the tightening strap 13 penetrates into the through hole 11c, the tightening strap 13 is circumferentially bound and tightened on the clamping body 11 along the clamping tube hole 11a, and thus the aperture of the clamping tube hole 11a can be reduced to a certain extent, so that the clamping body 11 can more stably clamp the pipe fitting 30. The inner wall of the clamping tube hole 11a can be brought into close contact with the outer wall of the pipe 30 by the clamping body 11 tightened by the tightening band 13, thereby more reliably fixing the pipe 30 and reducing the occurrence of movements such as axial play or radial vibration between the pipe 30 and the clamping body 11.

The material of the tightening band 13 is not limited, but for example, the tightening band 13 may be formed of a nylon band, a plastic seal, or the like having good acid resistance, corrosion resistance, and insulation properties to tighten the pipe 30.

In an embodiment, referring to fig. 1, 3 and 4, the top surface of the clamping body 11 is formed with a fastening sinking groove 11d, and the fastening strip 13 is accommodated in the fastening sinking groove 11 d. With such a design, the tightening band 13 can be positioned and assembled conveniently, and the tightening band 13 can be prevented from slipping off from the top surface of the clamping body 11, thereby improving the reliability of the tightening band 13.

Illustratively, the width of the tightening sunken groove 11d is slightly larger than the width of the tightening strap 13 so that the tightening strap 13 is accommodated in the tightening sunken groove 11d, and the depth of the tightening sunken groove 11d is slightly larger than the thickness of the tightening strap 13, so as to further prevent the tightening strap 13 from being separated from the tightening sunken groove 11d, and further improve the reliability of tightening the clamping body 11 by the tightening strap 13.

In one embodiment, referring to fig. 4 and 5, the number of the clamping tube holes 11a is multiple, the multiple clamping tube holes 11a are layered from the top side of the clamping body 11 to the bottom side of the clamping body 11, and the hole diameters of at least two clamping tube holes 11a are different. Like this, the clamping body 11 can adapt to the pipe fitting 30 of different external diameters, and the buckle 10 can regard as the standard component in order to adapt to the pipe fitting 30 of different external diameters, has reduced manufacturing cost, improves buckle 10's utilization ratio.

Illustratively, in one embodiment, the plurality of clamping tube holes 11a are arranged in order from the top side of the clamping body 11 to the bottom side of the clamping body 11. That is, the closer to the top side of the clamping body 11, the larger the bore diameter of the clamping tube hole 11a, and the closer to the bottom side of the clamping body 11, the smaller the bore diameter of the clamping tube hole 11 a. In another embodiment, referring to fig. 4 and 6, the plurality of clamping tube holes 11a are arranged in order from the top side of the clamping body 11 to the bottom side of the clamping body 11. That is to say, the top side that is closer to the clamping body 11 is, and the aperture of centre gripping tube hole 11a is less, and the bottom side that is closer to the clamping body 11 is, and the aperture of centre gripping tube hole 11a is big more, because the pipe fitting 30 self weight of great external diameter is heavier, drives clamping body 11 shake or skew more easily, consequently, sets up the relatively great centre gripping tube hole 11a in the bottom side of clamping body 11 in the aperture, further avoids the pipe fitting 30 of great external diameter to drive clamping body 11 skew. For example, the fixing lug 12 is disposed at the bottom of the clamping body 11, and the mounting groove 11b is formed at the top of the clamping body 11, so that the pipe 30 with a relatively large outer diameter is closer to the fixing lug 12, thereby further avoiding the problem that the pipe 30 drives the clamping body 11 to move or causes the mounting groove 11b to expand and deform.

In one embodiment, referring to fig. 4 and 6, the plurality of clamping tube holes 11a are sequentially communicated, a contraction area 111 is provided between two adjacent clamping tube holes 11a, and the pipe 30 can be restorably expanded into the lower clamping tube hole 11a by expanding the contraction area 111. That is, the width of the constricted region 111 is smaller than the width of the two clamping tube holes 11a adjacent thereto. On one hand, the contraction area 111 is communicated with the adjacent clamping pipe holes 11a, the pipe fitting 30 can downwards extrude the contraction area 111 from the upper clamping pipe hole 11a so as to restorably expand the contraction area 111, and directly enters the lower clamping pipe hole 11a, and the pipe fitting 30 is more convenient and faster to install. On the other hand, the contraction region 111 can play a role in limiting, so that the pipe 30 accommodated in the clamping pipe hole 11a can be limited to the current position to a certain extent, the condition that the pipe 30 moves or slides in the clamping pipe hole 11a can be reduced, and the pipe 30 is prevented from moving into the upper clamping pipe hole 11a or the lower clamping pipe hole 11 a.

In an embodiment, referring to fig. 4, 5, 6 and 7, the fixing lug 12 is located at the bottom of the clamping body 11, the fixing lug 12 is formed with fixing holes 12a penetrating through both sides of the top and bottom of the fixing lug 12, and the fixing holes 12a are used for penetrating the connecting member 20. Therefore, the fixing lug 12 can be conveniently connected to the air conditioning device through the connecting piece 20, the assembling difficulty is reduced, and the assembling efficiency is improved.

The fixing lugs 12 at the bottom of the clamping body 11 may be provided in any shape suitable for fixing so as to be adjusted according to the fixing environment around the actual pipe 30. Exemplarily, the fixing lugs 12 are arranged on the clamping body 11 along both sides of the pipe 30 in the radial direction, so that when the connecting member 20 is installed on the fixing lugs 12, the installation tool does not interfere with the pipe 30, the installation operation is humanized, and the installation is more stable.

In an embodiment, referring to fig. 4, 5, 6 and 7, a stepped surface 12a 'is formed on an inner circumferential surface of the fixing hole 12a, and the connecting member 20 can abut against the stepped surface 12 a'. The step surface 12 a' is provided in the fixing hole 12a, so that the connecting member 20 is buried inside the fixing hole 12a and does not exceed the top surface of the fixing lug 12, and thus, the connecting member 20 does not interfere with other external structures of the buckle 10, and the appearance of the buckle 10 is more regular.

The connection manner of the connection member 20 is not limited, and in an exemplary embodiment, the connection member 20 includes, but is not limited to, a screw, a bolt, and the like.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and all the changes or substitutions should be covered by the scope of the present application.
