[0032] In order to make the technical personnel of the prior art better understand the technical scheme of the utility model, the utility model is further explained in detail below in combination with specific implementation.

[0033] As Figure 1 Indicated, the utility model provides a kind of copper pipe quick connection tool, including by left and right two jaw bodies 1, the jaw body 1 includes the jaw jaw 11 for clamping copper pipe and the jaw handle 12 of facilitating operator holding;Left and right two jaw bodies 1 middle part cross-linking (for example, left and right two jaw bodies are all opened pin hole, and utilize pin shaft to pass through pin hole and link left and right two jaw bodies), so that can be controlled two jaw jaws 11 opening and closing by two jaw handles 12;The jaw jaw 11 is provided with initial pressure mechanism 2, shaping mechanism 3 and shaping mechanism 4.

[0034] The utility model discloses a principle is: through the initial pressure mechanism 2 to one end copper pipe is extruded and is reduced in diameter, so that the copper pipe of needing to connect one end diameter becomes small.

[0035] The utility model discloses through twice extrusion to copper pipe is reduced in diameter, avoids in turn to pressurize and reduces in diameter not in place, cannot be inserted into the copper pipe of another end. Three institutions are arranged on same tool, and convenient and practical, and single person can complete the connection of copper pipe fast. And the copper pipe joint after connecting is very firm, avoids falling in the process of traction. In addition, the utility model discloses still be provided with the shaping mechanism, so that the copper pipe junction is straight, avoids the connection skew influence subsequent traction.

[0036] As shown in Figure 2 The initial pressure mechanism 2 is used for extruding and reducing in diameter one end copper pipe. Specifically, the initial pressure mechanism 2 includes the forming groove I22 and the pressing block I23 arranged in the two jaw 11 inner sides respectively, when the two jaw 11 is closed, the pressing block I23 can be embedded in the forming groove I22, the forming groove I22 section is U-shaped, and the pressing block I23 section shape is consistent with the forming groove I22 section shape. More specifically, the initial pressure mechanism 2 includes the base I21, the forming groove I22 is opened on the base I21 and penetrates the base I21, and the base I21 is fixed in the jaw 11 inner side and is perpendicular to the jaw 11, more easily stressed.

[0037] The initial pressure mechanism 2 adopts the U-shaped forming groove I22, more easily forms, and is more suitable for extruding the cylindrical copper pipe.

[0038] The setting mechanism 3 is used for further extruding and setting the copper pipe after extruding and reducing in diameter, and is used for extruding and connecting after the copper pipe after extruding and setting is inserted into the copper pipe of another end. Specifically, the setting mechanism 3 includes the forming groove II32 and the pressing block II33 arranged in the two jaw 11 inner sides respectively, when the two jaw 11 is closed, the pressing block II33 can be embedded in the forming groove II32, the forming groove II32 section is rectangular, and the pressing block II33 section shape is consistent with the forming groove II32 section shape. More specifically, the setting mechanism 3 includes the base II31, the forming groove II32 is opened on the base II31 and penetrates the base II31, and the base II31 is fixed in the jaw 11 inner side and is perpendicular to the jaw 11, more easily stressed.

[0039] The shaping mechanism 3 adopts a rectangular forming groove II32, so that the connection is more stable and not easy to fall off, and relative rotation can also be avoided. The rectangular forming is relatively difficult, so the preliminary pressing mechanism 2 is needed to preliminarily reduce the diameter of the cylindrical copper pipe and then press it into a three-edge frame structure. After the end of the frame-shaped copper pipe is inserted into the end of another copper pipe, the two are extruded by the shaping mechanism 3 to be stably connected.

[0040] The shaping mechanism 4 is used for trimming the copper pipe after extrusion connection. Specifically, the shaping mechanism 4 includes half-molds 41 arranged on the inner sides of the two jaws 11, and the half-molds 41 are provided with mold cavities 42; when the two jaws 11 are closed, the mold cavities 42 on the two half-molds 41 can be spliced into a cylindrical inner cavity. The half-mold 42 is perpendicular to the jaw 11, and is also more easily stressed.

[0041] The shaping mechanism 4 can trim the connection of the two copper pipes to keep it straight, which is convenient for subsequent traction.

[0042] As shown in Figure 3 In some embodiments, the preliminary pressing mechanism 2, the shaping mechanism 3 and the shaping mechanism 4 are arranged in the above order along the jaws 11 from back to front. According to the principle of lever, the closer to the support point, the easier to operate the handle 12. The preliminary pressing is the most laborious, the shaping is the second, and the shaping needs the smallest driving force, so the three mechanisms are arranged in the above order.

[0043] In addition, in some embodiments, the lengths of the preliminary pressing mechanism 2 and the shaping mechanism 3 are consistent and greater than the width of the jaw 11; and the length of the shaping mechanism 4 is greater than that of the preliminary pressing mechanism 2 and the shaping mechanism 3, which is needed to straighten the copper pipe which is relatively longer than the connection section.

[0044] When the finishing work of the last coil of copper pipe is about to be completed, the tail end of the last coil of copper pipe and the head end of the next coil of copper pipe are connected by using the copper pipe quick connection tool according to the above method. After connection, the next coil of copper pipe is automatically fed into the finishing equipment by using the traction force of the finishing equipment itself, without manual pipe feeding.

[0045] The above is only the preferred embodiment of the present application, and it should be pointed out that the above preferred embodiment should not be regarded as a limitation of the present application, and the protection scope of the present application should be limited by the scope defined in the claims. For ordinary skilled in the art, some improvements and refinements can be made without departing from the spirit and scope of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
