Description

Technical Field

[0001] The utility model belongs to the technical field of connecting pipe components, and particularly relates to a metal connecting pipe component. Background Art

[0002] As a kind of connecting pipe in connecting conveying pipe fittings, it is widely used in equipment such as air conditioners. Before the existing connecting pipe components are used, different pipe fittings need to be combined. Their connection or installation methods mainly adopt interference or tight fitting for installation, and then solder is added at the connection for welding. This method improves the sealing performance of the installation under ideal conditions;

[0003] When the existing connecting pipe components are in use, after the pipe fittings are butted, the connecting pipe components are used to fix them, and then solder is added at the connection for welding. During the fixing process of this method, the connection may be loose and the butt joint may not be in place. During subsequent welding, the weld seam is large and the welding effect is poor. Summary of the Utility Model

[0004] To solve the problems raised in the above background art. The utility model provides a metal connecting pipe component, which includes a left clamping component and a right clamping component, and a centering and moving component is arranged between the bottoms of the left clamping component and the right clamping component;

[0005] The centering and moving component includes a U-shaped support. A rotating rod is arranged between the left and right ends of the U-shaped support through bearings, and a pair of guide rods for guiding are also included.

[0006] As a metal connecting pipe component of the utility model, preferably, external threads with opposite thread directions are respectively arranged at the left and right ends of the rotating rod, and the external threads at both ends of the rotating rod are respectively screwed into a left support and a right support.

[0007] As a metal connecting pipe component of the utility model, preferably, both the left support and the right support are sleeved on the guide rods, and both the left support and the right support slide left and right on the guide rods.

[0008] As a metal connecting pipe component of the utility model, preferably, a reduction motor is installed at the right end of the U-shaped support, and the output end of the reduction motor is fixedly connected to the rotating rod.

[0009] As a metal connecting pipe component of the utility model, preferably, the left support is fixedly connected to the left clamping component, and the right support is fixedly connected to the right clamping component.

[0010] As a metal connecting pipe component of the utility model, preferably, the left clamping component and the right clamping component have the same structure and size, and the two are symmetrically arranged left and right.

[0011] As a metal pipe connection component of the present utility model, preferably, the left clamping component includes a lower buckle fixed on the left support, the lower buckle is movably provided with an upper buckle through a hinge, and the lower buckle and the upper buckle are locked by pressing a locking wrench.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] Align the pipe fittings to be combined, then clamp and limit the pipe fittings to be combined through the left clamping component and the right clamping component. Finally, solder is added at the joint for welding. If the joint is not properly aligned and the gap becomes larger after combination, drive the reduction motor to drive the rotating rod to rotate. Since the thread directions at both ends of the rotating rod are opposite, and the left support and the right support are respectively screwed onto the threads in different directions at both ends of the rotating rod, the rotation of the rotating rod at this time drives the left support and the right support to move in opposite directions. Furthermore, the left clamping component and the right clamping component approach each other, thereby adjusting the gap at the joint and making the pipe fittings properly aligned, improving the welding effect.

[0025] Embodiment 1

[0026] As Figure 1 shown;

[0027] A metal pipe connection assembly includes a left clamping assembly 1 and a right clamping assembly 2.

[0028] In this implementation: To solve the technical problems existing in this prior art, as disclosed in the background art above, "when the existing pipe connection assemblies are in use, after the pipe fittings are docked, they are fixed by the pipe connection assembly, and then brazing filler metal is added at the connection for welding. In this way, during the fixing process, the connection may become loose, the docking may not be in place, and the weld seam is relatively large during subsequent welding, resulting in poor welding effect". Considering the actual use, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, a metal pipe connection assembly is provided herein.

[0029] As Figures 1-5 shown in the figure;

[0030] Combined with the above content, a centering and moving assembly 3 is provided between the bottoms of the left clamping assembly 1 and the right clamping assembly 2;

[0031] The centering and moving assembly 3 includes a U-shaped support 31. A rotating rod 32 is arranged between the left and right ends of the U-shaped support 31 through bearings, and a pair of guide rods 33 for guiding are provided.

[0032] In an optional embodiment, external threads with opposite thread directions are respectively provided at the left and right ends of the rotating rod 32, and the external threads at both ends of the rotating rod 32 are respectively screwed into a left support 34 and a right support 35.

[0033] In an optional embodiment, both the left support 34 and the right support 35 are sleeved on the guide rods 33, and both the left support 34 and the right support 35 slide left and right on the guide rods 33.

[0034] In an optional embodiment, a reduction motor 36 is installed at the right end of the U-shaped support 31, and the output end of the reduction motor 36 is fixedly connected to the rotating rod 32.

[0035] In an optional embodiment, the left support 34 is fixedly connected to the left clamping assembly 1, and the right support 35 is fixedly connected to the right clamping assembly 2.

[0036] In this embodiment: The driving reduction motor 36 drives the rotating rod 32 to rotate. Since the thread directions at both ends of the rotating rod 32 are opposite, and the left support 34 and the right support 35 are respectively screwed onto the threads in different directions at both ends of the rotating rod 32, at this time, the rotation of the rotating rod 32 drives the left support 34 and the right support 35 to move in opposite directions, and then the left clamping assembly 1 and the right clamping assembly 2 approach each other.

[0037] In an alternative embodiment, the left clamping assembly 1 and the right clamping assembly 2 are identical in structure and size, and are symmetrically arranged left and right.

[0038] In an alternative embodiment, the left clamping assembly 1 includes a lower buckle 11 fixed on the left support 34. The lower buckle 11 is movably provided with an upper buckle 12 through a hinge, and the lower buckle 11 and the upper buckle 12 are locked by a pressing locking wrench 13.

[0039] The working principle of the present utility model:

[0040] Align the pipe fittings to be combined, and then clamp and limit the pipe fittings to be combined through the left clamping assembly 1 and the right clamping assembly 2. Finally, solder is added at the joint for welding. If the joint is not properly aligned and the gap becomes larger after combination, the driving reduction motor 36 drives the rotating rod 32 to rotate. Since the thread directions at both ends of the rotating rod 32 are opposite, and the left support 34 and the right support 35 are respectively screwed onto the threads in different directions at both ends of the rotating rod 32, at this time, the rotation of the rotating rod 32 drives the left support 34 and the right support 35 to move in opposite directions, and then the left clamping assembly 1 and the right clamping assembly 2 approach each other, thereby adjusting the gap at the joint to make the pipe fittings properly aligned and improving the welding effect.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
