Description

Technical Field

[0001] The utility model relates to the technical field of heat pumps, in particular to a pipeline connection structure of an absorption heat pump. Background Art

[0002] The pipe connection structure of the absorption heat pump plays a vital role in the entire system. It is usually composed of pipes, connectors and seals made of different materials. Through reasonable pipe layout and connection methods, the various components of the absorption heat pump, such as the generator, condenser, evaporator, absorber, etc., are connected to form a closed circulation system, making the pipe connection simpler and faster, reducing installation costs and time, and allowing for easy disassembly and replacement of pipe components, thereby improving the maintainability of the system.

[0003] The existing Chinese patent with publication number CN209385841U provides an absorption heat pump that can quickly connect pipes, belonging to the field of heat pump technology. The locking sleeve is moved toward the butt-jointing pipe and rotated so that the internal thread in the locking sleeve engages with the external thread on the first mounting pipe, thereby firmly connecting the butt-jointing pipe and the connecting pipe.

[0004] Regarding the above-mentioned related technologies, the problem is that the threaded connection between the connecting pipe and the heat pump pipe is too tight, which makes disassembly difficult. Utility Model Content

[0005] The purpose of the utility model is to provide a pipe connection structure of an absorption heat pump. By adopting the device to work, the problem that the threaded connection between the connecting pipe and the heat pump pipe is too tight, which will lead to difficulty in disassembly is solved.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pipe connection structure of an absorption heat pump, comprising a heat pump pipe, a connecting pipe being provided on one side of the heat pump pipe, a connecting assembly being installed between the heat pump pipe and the connecting pipe, the connecting assembly comprising a connecting frame, the connecting frame being fixedly installed on the outside of the heat pump pipe, three notches being provided on the connecting frame, a rotating ring being installed in the connecting frame, a guide column being installed on the outside of the rotating ring, three connecting blocks being installed on the inside of the rotating ring, a fixing plate being installed on the connecting block, a fixing assembly being installed on one end of the connecting pipe close to the heat pump pipe, and the free end of the fixing assembly matching the notch.

[0007] Place one end of the connecting pipe against one end of the heat pump pipe, and insert the free end of the fixing assembly into the slot one. Adjust the guide column to make the rotating ring rotate clockwise. The rotating ring drives the connecting block to rotate, thereby causing the fixing plate to rotate clockwise. Insert one end of the fixing plate into the free end of the fixing assembly to fix the position of the fixing assembly, so that the connecting pipe and the heat pump pipe are tightly connected together.

[0008] Preferably, the fixing assembly includes a fixing ring, on which three fixing blocks are mounted, and the fixing blocks match the notches.

[0009] The fixing block is inserted into the first notch, and the fixing block prevents the connecting pipe from rotating.

[0010] Preferably, a second notch is provided on the fixing block, and the fixing plate matches the second notch.

[0011] The rotating ring rotates so that one end of the fixing plate is inserted into the second notch to fix the fixing block, thereby fixing the position of the connecting pipe.

[0012] Preferably, a notch is provided on the connecting frame, and the width of the notch is the same as the diameter of the guide column.

[0013] The guide column is adjusted to move along the notch, thereby driving the rotating ring to rotate.

[0014] Preferably, a screw rod is threadedly mounted on the connection frame, a knob is mounted on one end of the screw rod, a threaded hole is provided on the rotating ring, and the screw rod and the threaded hole match.

[0015] When the position of the fixing assembly is fixed, turning the knob drives the screw to rotate, so that the free end of the screw is threadedly connected to the threaded hole, thereby fixing the position of the rotating ring and preventing the connecting pipe from falling off due to the rotation of the rotating ring.

[0016] Preferably, a raised ring is installed at one end of the heat pump tube, a connecting groove is opened at one end of the connecting tube, the raised ring and the connecting groove are interference matched, and a gasket is installed in the connecting groove.

[0017] When the heat pump pipe and the connecting pipe are connected at both ends, the raised ring is inserted into the connecting groove, making the connection between the heat pump pipe and the connecting pipe tighter, and the gasket prevents leakage of the medium in the heat pump.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] Combine Figure 2-Figure 3The cam 33 is fixed on the top of the heat pump pipe 1, and the cam 33 is fixed on the top of the heat pump pipe 1. The cam 33 is fixed on the top of the heat pump pipe 1, and the cam 33 is fixed on the top of the heat pump pipe 1.

[0029] Combine Figure 2-Figure 3 The fixing assembly 35 includes a fixing ring 351, on which three fixing blocks 352 are installed. The fixing blocks 352 match the first slot 311, and the fixing blocks 352 are provided with a second slot 353. The fixing plate 34 matches the second slot 353. The fixing blocks 352 are inserted into the first slot 311. The fixing blocks 352 prevent the connecting pipe 2 from rotating by itself. The rotating ring 32 rotates so that one end of the fixing plate 34 is inserted into the second slot 353, thereby fixing the fixing blocks 352 and fixing the position of the connecting pipe 2.
