Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0032] The existing copper pipe supporting device is used to assist copper pipe welding to ensure the quality of copper pipe welding. The existing copper pipe supporting device includes a magnetic supporting device and a customized supporting device. The magnetic supporting device can be placed according to the position of the copper pipe, and the magnetic supporting device is convenient to install and disassemble, and has the characteristics of flexible positioning, but the magnetic supporting device is prone to tilting or toppling when supporting heavy or long copper pipes, that is, the stability of the magnetic supporting device is poor, which can affect the processing quality of copper pipe welding.

[0033] The customized supporting device needs to be customized according to the type of heat pump, and the customized supporting device cannot be disassembled, and the customized supporting device has good stability for supporting the copper pipe, but the customized supporting device cannot be adjusted in position according to the position of the copper pipe, that is, the customized supporting device does not have the characteristics of flexible positioning, so the customized supporting device needs to be replaced according to the heat pump model.

[0034] In view of the problem that the two supporting devices in the prior art cannot simultaneously satisfy the flexible positioning and stability of the copper pipe support in use, the present application provides a copper pipe supporting device.

[0035] As attached Figure 1 The diagram shown is a schematic representation of the overall structure of the copper tube support device in an embodiment of this utility model; as shown in the attached diagram. Figure 2 As shown, Figure 1 A magnified view of point A in the middle. (From the attached image) Figure 1 As can be seen from the diagram, the copper pipe support device includes a tooling base 1 and a copper pipe support frame 2.

[0036] The fixture base 1 includes a fixture base plate 11, which has fixing holes 111. The fixing holes 111 are used to fix the copper pipe support frame 2. For example, the fixture base 1 has multiple fixture base plates 11 arranged in an orderly manner, each with multiple fixing holes 111. The position of the copper pipe support frame 2 can be determined according to the position of the copper pipe, so that the copper pipe support frame 2 can be fixed in a suitable position at the fixing holes 111. That is, the positions of the multiple fixing holes 111 are different, which facilitates the adjustment of the position of the copper pipe support frame 2, allowing the copper pipe support frame 2 to be flexibly positioned according to the position of the copper pipe.

[0037] The copper pipe support frame 2 includes a connecting rod 21, a connecting part 22, a support rod 23, and a copper pipe bracket 24. The connecting rod 21 is detachably connected to the fixing hole 111, that is, the copper pipe support frame 2 is detachably connected to the fixing hole 111. For example, the fixing hole 111 has an internal thread in its wall, and the connecting rod 21 has an external thread. The fixing hole 111 and the connecting rod 21 are connected by the internal and external threads. Further, a fixing nut is fitted onto the end of the connecting rod 21 connected to the fixing hole 111 to increase the stability of the connection between the connecting rod 21 and the fixing hole 111, thereby increasing the stability when supporting the copper pipe.

[0038] The connecting part 22 is sleeved on the connecting rod 21, and its position on the connecting rod 21 is adjustable, allowing for adjustment of its height and horizontal orientation. For example, the connecting rod 21 is cylindrical. On one hand, the connecting part 22 can move up and down relative to the connecting rod 21 to change its height. On the other hand, the connecting part 22 can rotate around the connecting rod 21 to change its horizontal orientation. Thus, the connecting part 22 can be adjusted according to the position of the copper pipe for better positioning, thereby enabling the copper pipe support frame 2 to support the copper pipe. Understandably, the connection between the connecting part 22 and the connecting rod 21 increases the stability of the copper pipe support device when supporting the copper pipe.

[0039] The support rod 23 is detachably connected with the connecting portion 22 at one end and connected with the copper pipe bracket 24 at the other end, that is, the support rod 23 has a connection relationship with the connecting portion 22 and the copper pipe bracket 24, and when the copper pipe bracket 24 supports the copper pipe, the stability of supporting the copper pipe can be ensured. The position of the support rod 23 relative to the connecting portion 22 is adjustable, that is, the position of the copper pipe bracket 24 is adjusted by adjusting the position of the support rod 23, so that the copper pipe bracket 24 can be adjusted in position according to the position of the copper pipe, and then flexible positioning of the copper pipe is realized. Understandably, when the height position, the horizontal direction of the connecting portion 22, and the position of the support rod 23 relative to the connecting portion 22 are adjusted, the position of the copper pipe bracket 24 can be changed, that is, the height position, the horizontal direction of the copper pipe, and the distance relative to the connecting portion 22 can be adjusted, so that the copper pipe bracket 24 can be adjusted according to the position of the copper pipe to support the copper pipe.

[0040] The support rod 23 is perpendicular to the connecting rod 21, that is, the axial direction of the support rod 23 is perpendicular to the axial direction of the connecting rod 21. When the height position of the connecting portion 22 is adjusted, the height position of the copper pipe bracket 24 can be adjusted, and when the position of the support rod 23 relative to the connecting portion 22 is adjusted, the horizontal position of the copper pipe bracket 24 can be adjusted.

[0041] As shown in the accompanying drawings, Figure 2 The copper pipe bracket 24 is provided with a limiting groove 241 for supporting and limiting the copper pipe. The copper pipe is located in the limiting groove 241, and the limiting groove 241 supports and limits the copper pipe when the copper pipe is welded to prevent the copper pipe from moving and affecting the welding quality. Exemplarily, the number of limiting grooves 241 is three, and the three limiting grooves 241 are arranged above and on both sides of the connecting portion 22, which can limit the copper pipe in the X-axis, Y-axis and Z-axis directions.

[0042] From the above embodiment, the position of the connecting portion 22 on the connecting rod 21 is adjustable, and the position of the support rod 23 relative to the connecting portion 22 is adjustable, so that the copper pipe can be flexibly positioned when the copper pipe supporting device is used. On the other hand, the connecting portion 22 is sleeved on the connecting rod 21, and one end of the support rod 23 is detachably connected with the connecting portion 22 and the other end is connected with the copper pipe bracket 24, so that the copper pipe can be stably supported when the copper pipe supporting device is used.

[0043] As shown in the accompanying drawings, Figures 2-5As shown, in some embodiments, the connecting portion 22 is provided with a first connecting hole 221 and a first positioning pin 222 connected with the first connecting hole 221, and the connecting rod 21 is arranged in the first connecting hole 221, and the first positioning pin 222 is used to fix the connecting rod 21 in the first connecting hole 221. The connecting rod 21 can move in the first connecting hole 221, and after the position of the connecting rod 21 is adjusted, the connecting rod 21 can be fixed by the first positioning pin 222, thereby increasing the stability of the copper pipe supporting device when supporting the copper pipe.

[0044] In some embodiments, the connecting portion 22 is provided with a first limiting hole 223, the first limiting hole 223 is in communication with the first connecting hole 221, and the hole axis of the first limiting hole 223 is perpendicular to the hole axis of the first connecting hole 221. The hole axis refers to a line extending along the axis of the hole. The first positioning pin 222 is arranged in the first limiting hole 223, and the first positioning pin 222 includes a first loosening state and a first fixed state. When the first positioning pin 222 moves in the first limiting hole 223, the connecting rod 21 in the first connecting hole 221 can be squeezed or released, thereby realizing loosening and fixing of the connecting rod 21. When the connecting rod 21 is arranged in the first connecting hole 221 and the first positioning pin 222 is in the first loosening state, the connecting rod 21 can move in the first connecting hole 221; when the connecting rod 21 is arranged in the first connecting hole 221 and the first positioning pin 222 is in the first fixed state, the connecting rod 21 is fixed in the first connecting hole 221. The positions of the first positioning pin 222 in the first loosening state and the first fixed state are different.

[0045] Exemplarily, when the first positioning pin 222 moves in the first limiting hole 223, the length of the first positioning pin 222 extending into the first connecting hole 221 can be changed. When the first positioning pin 222 is in the first fixed state, the length of the first positioning pin 222 extending into the first connecting hole 221 is relatively long, and one end of the first positioning pin 222 extending into the first connecting hole 221 squeezes the connecting rod 21, so that the connecting rod 21 is fixed in the first connecting hole 221. When the first positioning pin 222 is in the first loosening state, the first positioning pin 222 does not extend into the first connecting hole 221, and the first positioning pin 222 does not squeeze the connecting rod 21, so that the connecting rod 21 can move in the first connecting hole 221.

[0046] As shown in FIG. 1, the copper pipe supporting device includes a connecting portion 22 and a connecting rod 21. The connecting portion 22 is arranged on the copper pipe 1, and the connecting rod 21 is arranged on the copper pipe 2. The connecting portion 22 is provided with a first connecting hole 221 and a first positioning pin 222 connected with the first connecting hole 221, and the connecting rod 21 is arranged in the first connecting hole 221. The first positioning pin 222 is used to fix the connecting rod 21 in the first connecting hole 221. The connecting rod 21 can move in the first connecting hole 221, and after the position of the connecting rod 21 is adjusted, the connecting rod 21 can be fixed by the first positioning pin 222, thereby increasing the stability of the copper pipe supporting device when supporting the copper pipe. Figures 2-5As shown in the drawings, in some embodiments, the connecting portion 22 is provided with a second connecting hole 224, and a second positioning pin 225 connected with the second connecting hole 224, and the support rod 23 is arranged in the second connecting hole 224, and the second positioning pin 225 is used to fix the support rod 23 in the second connecting hole 224. Similarly, the support rod 23 can move in the second connecting hole 224, and after the position of the support rod 23 is adjusted, the support rod 23 can be fixed by the second positioning pin 225, thereby increasing the stability of the copper pipe supporting device when supporting the copper pipe.

[0047] In some embodiments, the connecting portion 22 is provided with a second limiting hole 226, the second limiting hole 226 is communicated with the second connecting hole 224, and the hole axis of the second limiting hole 226 is perpendicular to the hole axis of the second connecting hole 224, the second positioning pin 225 is arranged in the second limiting hole 226, and the second positioning pin 225 comprises a second loosening state and a second fixing state. When the second positioning pin 225 moves in the second limiting hole 226, the support rod 23 in the second connecting hole 224 can be pressed or released, thereby realizing the loosening and fixing of the support rod 23. When the support rod 23 is arranged in the second connecting hole 224 and the second positioning pin 225 is in the loosening state, the support rod 23 can move in the second connecting hole 224. When the support rod 23 is arranged in the second connecting hole 224 and the second positioning pin 225 is in the fixing state, the support rod 23 is fixed in the second connecting hole 224. The positions of the second positioning pin 225 in the second loosening state and the second fixing state are different.

When the support rod 23 is located in the second connecting hole 224, the support rod 23 can pass through the movable hole 2251. When the second positioning pin 225 is pressed, the elastic element 2261 is compressed, the overlapping area of the movable hole 2251 and the second connecting hole 224 is increased, that is, the activity space of the support rod 23 provided by the movable hole 2251 is increased, and the support rod 23 can move in the movable hole 2251 and the second connecting hole 224. When the second positioning pin 225 is released, the elastic element 2261 is reset, the overlapping area of the movable hole 2251 and the second connecting hole 224 is reduced, that is, the activity space of the support rod 23 provided by the movable hole 2251 is reduced, and the second positioning pin 225 presses the support rod 23, so that the support rod 23 is fixed in the second connecting hole 224. The overlapping area of the movable hole 2251 and the second connecting hole 224 refers to the overlapping area of the shadow in the axial direction of the movable hole 2251 and the second connecting hole 224.
