[0045] As described in the background technology, the related art has the problem that the fixing block has harsh use conditions and cannot be used flexibly. In addition, the related art also has a solution to solve the stress and strain of the pipeline 200 by using a damping block, but the damping block has the problem that it cannot be used to fix the high-temperature pipeline 200, and the same damping block can only reduce the natural frequency of a section of the pipeline 200. If the stress exceeds the standard, the thickness and weight of the damping block can only be further increased, which will lead to the problem of large occupied area and cumbersome operation.

[0046] See also Figures 1 to 5 In order to solve the above problems, a fixing device 100 provided in an embodiment of the present application includes an adjustable connector 10 and two pipe fixing members 30. The two pipe fixing members 30 are used to respectively connect different pipe sections of the pipeline 200. One of the two pipe fixing members 30 is rotatably connected to a first position on the adjustable connector 10, and the other of the two pipe fixing members 30 is rotatably connected to a second position on the adjustable connector 10. The adjustable connector 10 is configured to be able to controllably and steplessly adjust the distance between the first position and the second position.

[0047] The fixing device 100 is used on the pipe 200 of the air conditioner outdoor unit. The pipe 200 of the air conditioner outdoor unit may be bent due to layout reasons. The bend can also be regarded as formed by bending and connecting two pipe sections with different extension directions. In order to reduce the probability of stress fatigue caused by excessive stress and strain due to external factors such as mineral refrigerant impact and unit vibration, the fixing device 100 is required to relatively fix the two pipe sections formed by the bend.

[0048] The adjustable connector 10 is configured to be able to controllably and steplessly adjust the distance between the first position and the second position, that is, to adjust the distance between the tube fixing member 30 provided at the first position and the tube fixing member 30 provided at the second position. The distance between the first position and the second position has a maximum value and a minimum value, and the stepless adjustment means that the distance between the first position and the second position can be arbitrarily adjusted and maintained between the maximum value and the minimum value. The first position and the second position are respectively located at two different parts of the adjustable connector 10, and the two parts can achieve relative movement by translation, rotation, etc.

[0049] When in use, first adjust the distance between the first position and the second position to be large enough so that the two pipe fixing members 30 can be connected to the target pipe segment. After the two pipe fixing members 30 are rotated to a suitable angle and fixed to the target pipe segment, the distance between the first position and the second position is adjusted by the adjustable connector 10, and the two pipe fixing members 30 are tightened so that the positions of the two pipe segments connected are relatively fixed, and the degree of tightening can be determined by the stress between the two pipe segments. Among them, the connection method between the pipe fixing member 30 and the pipeline 200 can be, but is not limited to, clamping, binding, bonding, etc. It can be understood that under normal working conditions, the distance between the first position and the second position only changes during controlled adjustment, and is relatively fixed after the adjustment is completed.

[0050] Accordingly, to dismantle the fixing device 100 , it is only necessary to adjust the distance between the first position and the second position to be large enough so that the two pipe fixing members 30 are separated from the pipeline 200 .

[0051] The fixing device 100 adjusts the distance between the two pipe fixing members 30 through the adjustable connector 10, and rotates the two pipe fixing members 30 to a suitable angle, so that the two pipe fixing members 30 can be connected to the pipes 200 bent at different angles. After the connection is completed, the two pipe fixing members 30 are tightened through the adjustable connector 10, so that the pipes 200 fixed by the two can be maintained in a relatively fixed position. In this way, the fixing device 100 can be used for various bending angles and single pipes, resisting the stress and strain on the pipe 200, and reducing the probability of the pipe 200 ruptured due to stress fatigue.

[0052] See also Figures 6 to 9 In some embodiments, the pipe fixing member 30 includes a connected clamping jaw 31 and a rotating connection portion 33, the clamping jaw 31 has a receiving groove 311 for receiving the pipeline 200 and a jaw opening 313 communicating with the receiving groove 311, and the receiving groove 311 extends along the length direction of the clamping jaw 31. The pipe fixing member 30 is rotatably connected to the adjustable connecting member 10 through the rotating connection portion 33, and the rotation axis intersects with the length direction of the clamping jaw 31.

[0053] The pipe fixing member 30 is connected to the pipeline 200 through the clamping jaws 31, and the size of the receiving groove 311 thereof should match the diameter of the pipe section to be connected. Specifically, the receiving groove 311 is columnar and passes through the clamping jaws 31 in its extending direction, and one side of the receiving groove 311 is a notch as a jaw opening 313. It can be understood that the clamping jaw 31 can be elastically deformed, and the arc occupied by the jaw opening 313 is less than π, and specifically less than π / 2, and the edge of the clamping jaw 31 at the jaw opening 313 can be constructed as a circular arc transition.

[0054] The pipeline 200 is inserted into the receiving groove 311 through the claw opening 313 by elastically deforming the clamping jaw 31, and the clamping jaw 31 recovers and clamps the pipeline 200 in the receiving groove 311, thereby completing the connection and fixation of the pipeline 200. The two pipe fixing members 30 can adapt to the angle of the connected pipe section by rotating. Specifically, the rotation axis of the rotating connection part 33 is perpendicular to the length direction of the clamping jaw 31.

[0055] In the related art, the assembly of the pipe fixing block and the damping block is relatively complicated and needs to be fastened with wire ties. When disassembling, the wire ties need to be removed, and the removed damping block and wire ties cannot be reused, resulting in a waste of resources. In contrast, the method of fixing the connecting pipe 200 with the clamping jaw 31 does not require a wire tie, and is easy to disassemble and reuse.

[0056] Furthermore, the pipe fixing member 30 further includes a connecting arm 35 , which connects the clamping jaw 31 and the rotating connecting portion 33 , and the cross section of the connecting arm 35 perpendicular to its longitudinal direction is an I-shape.

[0057] The extension direction of the connecting arm 35 may intersect with the length direction of the clamping jaw 31 and the length direction of the adjustable connecting member 10. Specifically, the extension direction of the connecting arm 35, the length direction of the adjustable connecting member 10 and the length direction of the clamping jaw 31 are perpendicular to each other. The two ends of the connecting arm 35 in its extension direction are respectively connected to the clamping jaw 31 and the rotating connecting portion 33.

[0058] In this way, the clamping jaw 31 can be pulled away from the adjustable connecting member 10 by a certain distance through the connecting arm 35, reducing the probability of interference between the two, and making the clamping jaw 31 rotate more flexibly. The connecting arm 35 adopts an I-shaped structure to achieve lightweight while ensuring its structural strength.

[0059] Please also read Figures 10 to 14 Further, the adjustable connector 10 has a first hinge bracket 11, the rotating connection portion 33 is a second hinge bracket matched with the first hinge bracket 11, and the pipe fixing member 30 is hinged to the adjustable connector 10 through the second hinge bracket and the first hinge bracket 11. The hinge between the pipe fixing member 30 and the adjustable connector 10 is a detachable connection, and the clamping jaw 31 with a size matching the receiving groove 311 can be replaced according to the diameter of the target pipeline 200.

[0060] In this way, the rotational connection between the pipe fixing member 30 and the adjustable connecting member 10 is achieved through hinge connection, and the structure is simple.

[0061] In a specific embodiment, the first hinge bracket 11 includes two hinge plates arranged at intervals, and the two hinge plates are provided with coaxial hinge holes. The second hinge bracket includes a hinge plate, and is also provided with a hinge hole. During assembly, the hinge plate of the second hinge bracket is inserted between the two hinge plates of the first hinge bracket 11, and all the hinge holes are aligned, and then the pin 111 is inserted into the hinge hole to achieve hinge connection.

[0062] It can be understood that in other embodiments, the first articulated bracket 11 may include one articulated plate, the second articulated bracket may include two articulated plates, or the first articulated bracket 11 and the second articulated bracket may each include two articulated plates, etc. It is sufficient as long as the pipe fixing member 30 can be articulated with the adjustable connecting member 10 through the second articulated bracket and the first articulated bracket 11, and no specific limitation is made here.

[0063] In some embodiments, the adjustable connecting member 10 includes a first connecting rod 13 and a second connecting rod 15, the first position is located on the first connecting rod 13, the second position is located on the second connecting rod 15, and the second connecting rod 15 is configured to be able to extend and retract relative to the first connecting rod 13 to steplessly adjust the distance between the first position and the second position.

[0064] The first connecting rod 13 and the second connecting rod 15 can be arranged in parallel or in a colinear manner. The second connecting rod 15 can be extended and retracted by moving relative to the first connecting rod 13, thereby changing the distance between the second position on the second connecting rod 15 and the first position on the first connecting rod 13. The extension direction is the rod length direction of the first connecting rod 13 and the second connecting rod 15. The first connecting rod 13 and the second connecting rod 15 both have a first articulated bracket 11. The first position is located on the first articulated bracket 11 of the first connecting rod 13, and the first articulated bracket 11 is located at one end of the first connecting rod 13 away from the second connecting rod 15. The second position is located on the first articulated bracket 11 of the second connecting rod 15, and the first articulated bracket 11 is located at one end of the second connecting rod 15 away from the first connecting rod 13.

[0065] Thus, the distance between the first position and the second position, that is, the distance between the two pipe fixing members 30, can be changed by only driving the second connecting rod 15 to extend and retract relative to the first connecting rod 13 and changing the extension amount of the second connecting rod 15 relative to the first connecting rod 13.

[0066] In some other embodiments, the second connecting rod 15 may also be configured to achieve stepless adjustment of the distance between the first position and the second position by rotating relative to the first connecting rod 13, etc., which is not specifically limited here.

[0067] Please also read Figures 15 to 17 Further, the adjustable connector 10 further includes an adjusting nut 17, which is rotatably arranged on the first connecting rod 13 around its own axis. The second connecting rod 15 is threaded at least partially in its rod length direction and cooperates with the adjusting nut 17.

[0068] In addition to the first articulated bracket 11 , the second connecting rod 15 further comprises a second rod body 151 . The second rod body 151 is connected to the first articulated bracket 11 and has an external thread on the circumference thereof that matches the adjusting nut 17 .

[0069] It can be understood that the second rod body 151 is inserted into the adjusting nut 17, and the adjusting nut 17 has a threaded hole 1711, and the size and internal thread of the threaded hole 1711 match the second rod body 151. The adjusting nut 17 is rotatably connected to the first connecting rod 13, and can rotate around its own axis, while being fixed relative to the first connecting rod 13 in the axial direction. In other words, the adjusting nut 17 can freely rotate around its own axis relative to the first connecting rod 13, and other degrees of freedom are restricted.

[0070] The axis of the adjusting nut 17 is also the axis of the threaded hole 1711. When the adjusting nut 17 is rotated, it can naturally drive the second connecting rod 15 matched therewith to move. At this time, the tightening degree can be based on the torque required to rotate the adjusting nut 17. For example, the adjusting nut 17 can be rotated by a device such as a torque wrench until the adjusting nut 17 cannot be rotated, and the tightening degree reaches the requirement.

[0071] In this way, the user can drive the second connecting rod 15 to extend and retract along the length direction of the second connecting rod 15 by rotating the adjusting nut 17 , that is, to extend and retract relative to the first connecting rod 13 connected to the adjusting nut 17 .

[0072] Furthermore, the first connecting rod 13 and the second connecting rod 15 have the same rod length direction, and the first connecting rod 13 has a receiving space 131, which extends along the rod length direction and can accommodate at least a portion of the second connecting rod 15, and the threaded hole 1711 of the adjusting nut 17 is connected to the receiving space 131.

[0073] The accommodation space 131 is used to accommodate the second rod 151, and the second rod 151 can move in the accommodation space 131. Specifically, the second rod 151 can pass through the adjustment nut 17 and enter the accommodation space 131. When the second connecting rod 15 extends relative to the first connecting rod 13, the second rod 151 moves in a direction away from the accommodation space 131, and when the second connecting rod 15 contracts relative to the first connecting rod 13, the second rod 151 moves in a direction entering the accommodation space 131.

[0074] In other words, when part of the second rod body 151 is accommodated in the accommodating space 131, the first connecting rod 13 and the second connecting rod 15 partially overlap in the length direction, and the more the second rod body 151 is accommodated in the accommodating space 131, the smaller the distance between the first position and the second position, and the less the second rod body 151 is accommodated in the accommodating space 131, the larger the distance between the first position and the second position.

[0075] In this way, the accommodating space 131 can not only accommodate the first connecting rod 13 , but also guide the extension and retraction of the first connecting rod 13 , making the extension and retraction process more stable.

[0076] In some embodiments, the adjusting nut 17 has a connected nut portion 171 and a matching portion 173, the nut portion 171 has a threaded hole 1711, and the matching portion 173 has a limiting slot 1731 in communication with the threaded hole 1711. The first connecting rod 13 includes an annular buckle 133, and the annular buckle 133 surrounds the accommodating space 131. The first connecting rod 13 is inserted into the limiting slot 1731 through the buckle end 1331 of the annular buckle 133, and is rotatably connected to the adjusting nut 17.

[0077] The buckle end 1331 of the annular buckle 133 can be inserted into the limiting slot 1731 and rotate in the limiting slot 1731. The annular buckle 133 surrounds the accommodating space 131, and the accommodating space 131 can also be regarded as at least partially defined by the annular buckle 133.

[0078] In this way, the adjusting nut 17 can smoothly realize rotational connection with the first connecting rod 13 , and at the same time, it does not affect the second connecting rod 15 passing through the adjusting nut 17 and the buckle end 1331 of the annular buckle 133 and being accommodated in the accommodating space 131 .

[0079] Furthermore, the first connecting rod 13 also includes a first rod body 135, the annular buckle 133 includes a plurality of sub-buckles 1333, all of the sub-buckles 1333 are spaced apart from each other in the circumferential direction around the length of the rod, each sub-buckle 1333 extends along the length of the rod and is connected to the first rod body 135, and all of the sub-buckles 1333 surround the accommodating space 131.

[0080] It can be understood that each sub-clip 1333 can undergo elastic deformation, and since there are intervals between the sub-clip 1333, there is space between the sub-clip 1333 to get close to each other. All the sub-clip 1333 can undergo elastic deformation under the action of external force, reduce the gap and get close to each other, and when the external force is eliminated or reduced, they are separated again under the action of elastic force and the gap size is restored.

[0081] Thus, in the process of being inserted into the limiting slot 1731, the sub-buckles 1333 are squeezed against each other, the gap is reduced and they are close to each other, so that the buckle end 1331 of the annular buckle 133 as a whole is reduced and smoothly enters the limiting slot 1731. After entering the limiting slot 1731, they are separated from each other again under the action of elastic force, so that the buckle end 1331 becomes larger and is firmly stuck in the limiting slot 1731, reducing the probability of the adjustment nut 17 and the first connecting rod 13 being separated.

[0082] Furthermore, the matching portion 173 also has an introduction groove 1733, which is located at one end of the limiting slot 1731 away from the threaded hole 1711 and communicates with the limiting slot 1731. The diameter of the introduction groove 1733 gradually decreases in the direction close to the limiting slot 1731. The introduction groove 1733 is an annular through groove, and its interior can be arc-shaped.

[0083] In this way, the buckle end 1331 of the annular buckle 133 can pass through the introduction groove 1733 and be inserted into the limiting buckle groove 1731 under the guidance of the introduction groove 1733 .

[0084] In some embodiments, at least a portion of the outer circumference of the adjusting nut 17 has a counterweight block slot 175, and the counterweight block slot 175 is used to assemble the counterweight block and provide a limit for the counterweight block.

[0085] Specifically, the surface of the matching portion 173 is surrounded by a plurality of T-shaped bosses 177 , a counterweight slot 175 is formed between two adjacent T-shaped bosses 177 , and six bosses 177 may be provided on the surface of the matching portion 173 , and six counterweight slots 175 are formed accordingly.

[0086] In this way, the user can flexibly add counterweights as needed, increase the weight at the corresponding position, and reduce the natural frequency of the pipeline 200.

[0087] In some embodiments, at least a portion of the outer circumference of the adjusting nut 17 is in the shape of a polyhedron surrounding its axis.

[0088] Specifically, the surface of the nut portion 171 is formed as a polyhedron surrounding the axis, and may specifically be, but not limited to, four-sided, five-sided, six-sided, etc.

[0089] In this way, the polyhedral surface facilitates the application of force, especially facilitates the use of tools such as a wrench to tighten the adjustment nut 17 .

[0090] In some embodiments, the pipe fixture 30 is an injection molded part, and other parts of the fixture 100 except the pipe fixture 30 may be, but not limited to, injection molded parts or metal parts (eg, aluminum alloy material). In this way, the fixture 100 can adapt to the high-temperature pipeline 200 .

[0091] When assembling the above-mentioned fixing device 100, the adjusting nut 17 is rotated to adjust the extension length of the second connecting rod 15 until the clamping jaw 31 can be inserted into the corresponding pipeline 200. After the clamping jaw 31 is inserted into the pipeline 200, the adjusting nut 17 is manually tightened, and then the assembly is completed by further tightening it with a wrench. When the electrical box needs to be disassembled, the adjusting nut 17 is loosened with a wrench until the clamping jaw 31 is separated from the pipeline 200. After the fixing device 100 is assembled, if the corresponding pipeline 200 still has the problem of excessive stress and strain, the weight of the corresponding position can be further increased by inserting the counterweight block into the counterweight block slot 175 of the adjusting nut 17, thereby reducing the natural frequency of the pipeline 200. In this way, the fixing device 100 can be used for various bending angles and single pipes to resist the stress and strain on the application pipeline 200, and reduce the probability of the pipeline 200 rupture caused by stress fatigue. In addition, the fixing device 100 also has the advantages of small footprint, simple disassembly and assembly, reusability, and suitability for high-temperature pipelines 200.

[0092] The present application also provides an air conditioner, comprising the above-mentioned fixing device 100.
