Description

Technical Field

[0001] This utility model relates to the field of air conditioning and refrigeration technology, and in particular to an auxiliary mechanism for connecting air conditioning and refrigeration pipelines. Background Technology

[0002] Air conditioning refrigeration piping is the piping used to transport refrigerant in an air conditioning system. The refrigeration piping connects major components such as the compressor, condenser, evaporator, and expansion valve into a complete refrigeration cycle system, allowing the refrigerant to flow between these components and complete processes such as compression, condensation, expansion, and evaporation, thereby achieving heat transfer and a cooling effect.

[0003] Chinese Patent CN215295350U discloses an auxiliary positioning accessory for refrigeration and air conditioning, including a sleeve, a fixing mechanism at one end of the sleeve, and a connecting mechanism at the other end of the sleeve. The fixing mechanism includes a fixing seat on the sleeve, and the connecting mechanism includes an adjusting screw slidably mounted on the sleeve. One end of the adjusting screw extends into the sleeve, and the other end is provided with a positioning component for fixing the pipeline. The sleeve has an adjusting nut that is threadedly engaged with the adjusting screw, and the adjusting nut is rotatably mounted on the sleeve. The sleeve also has a limiting component for restricting the rotation of the adjusting nut. This auxiliary accessory has a simple structure, is easy to install and use, and can limit and fix the refrigeration and air conditioning pipeline, preventing the pipeline from moving during the operation of the refrigeration and air conditioning system. It also improves the wind resistance of the pipeline, helping to prevent pipeline damage, reduces noise during use, and improves the user experience.

[0004] However, the above technical solution has the following shortcomings: when the height is adjusted by adjusting the adjusting nut, although the adjusting screw can lock the adjusting nut, it also limits the extension function of the adjusting screw, which means that the height can only be adjusted in one go, reducing the practicality of the auxiliary accessories. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing an auxiliary mechanism for connecting air conditioning refrigeration pipes. This mechanism can lock the adjusting nut in both forward and reverse rotation, and at the same time facilitates the correction of the distance of the adjusting rod extension, thereby improving the ease of use of the auxiliary mechanism for connecting pipes.

[0006] The present invention provides an auxiliary mechanism for connecting air conditioning refrigeration pipes, comprising a fixed cylinder and a limiting mechanism. An adjusting rod is slidably connected inside the fixed cylinder, and an adjusting nut is threaded onto the adjusting rod. An installation ring is provided on the fixed cylinder, and the adjusting nut is rotatably connected to the installation ring. The limiting mechanism comprises six ring-shaped arrayed frames, a rod slidably connected to the frames, a convex ring coaxially mounted on the rod, a spring with its two ends respectively mounted on the frame and the convex ring, a connecting ring with a collar mounted on the rod, and a pin slidably connected to the collar. The adjusting nut has a groove for the rod to be inserted, and the fixed cylinder has two vertically distributed positioning holes.

[0007] Preferably, the adjusting rod is provided with a clamping assembly, which includes a connector on the adjusting rod, a fixing ring with an elastic anti-slip pad, a connecting plate on the fixing ring, a second bolt passing through the fixing ring, and a second nut threadedly connected to the second bolt.

[0008] Preferably, a first bolt is provided through the connector and the connecting plate, and a first nut is threaded onto the first bolt.

[0009] Preferably, the adjusting rod is provided with four guide blocks arranged in a ring array, and the inside of the fixed cylinder is provided with a sliding groove for the guide blocks to slide.

[0010] Preferably, the convex ring is provided with two symmetrically distributed, T-shaped sliders, which are slidably mounted on the frame.

[0011] Preferably, the mounting ring is provided with a detachable protective cover, the protective cover and the adjusting nut abut against each other, and six third bolts are provided through the mounting ring, the third bolts and the protective cover being threadedly connected.

[0012] Preferably, a retaining ring is coaxially provided on the protective cover, and an annular groove that matches the retaining ring is provided on the adjusting nut.

[0013] Preferably, the fixed cylinder is provided with a mounting plate, and the mounting plate is provided with a plurality of fourth bolts arranged in a ring.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] This utility model achieves the locking effect of the adjusting nut through the setting of the limiting mechanism, which not only prevents the adjusting nut from rotating on its own, thus improving the stability and reliability of the pipeline fixing, but also allows the adjusting nut to rotate in the opposite direction, thus preventing the inability to adjust the position of the adjusting rod. It is simple and convenient to operate and has good practicality. Attached Figure Description

[0022] like Figures 1-5 As shown in the figure, the air conditioning refrigeration pipe connection auxiliary mechanism proposed in this embodiment includes a fixed cylinder 1 and a limiting mechanism; an adjusting rod 2 is slidably connected inside the fixed cylinder 1, and an adjusting nut 12 is threadedly connected to the adjusting rod 2; an installation ring 11 is provided on the fixed cylinder 1, and the adjusting nut 12 is rotatably connected to the installation ring 11; four guide blocks 13 are arranged in a ring array on the adjusting rod 2; and a sliding groove is provided inside the fixed cylinder 1 for the guide blocks 13 to slide. When the adjusting nut 12 is rotated, the adjusting nut 12 and the adjusting rod 2 are threaded together, and under the guidance of the guide blocks 13 and the sliding groove, the adjusting rod 2 will move along the direction of the sliding groove, thereby realizing the adjustment of the extension distance of the adjusting rod 2.

[0023] like Figures 2-4 As shown, the limiting mechanism includes six ring-shaped arrayed frames 14, a rod 15 slidably connected to the frame 14, a convex ring 16 coaxially mounted on the rod 15, a spring 17 with its two ends respectively mounted on the frame 14 and the convex ring 16, a connecting ring 18 mounted on the rod 15 and having a collar 19, and a pin 20 slidably connected to the collar 19; the adjusting nut 12 is provided with a groove for the rod 15 to be inserted, and the fixed cylinder 1 is provided with two positioning holes 21 distributed vertically.

[0024] In this example, before rotating the adjusting nut 12, first pull the pin 20 out of the upper positioning hole 21, then pull the connecting ring 18 downwards, so that the collar 19 and the rod 15 move downwards simultaneously until the pin 20 can be inserted into the lower positioning hole 21. At this time, the top of the rod 15 moves out of the groove of the adjusting nut 12, and the spring 17 is compressed under the action of the convex ring 16. Then the adjusting nut 12 can be rotated to adjust the distance of the adjusting rod 2 extending out of the fixed cylinder 1. After the adjustment is completed, pull out the pin 20, and the rod 15 is reinserted into the groove under the action of the spring 17. If the rod 15 is not aligned with the groove, the adjusting nut 12 can be finely adjusted again until the rod 15 is inserted into the groove, thereby locking the adjusting nut 12. This not only prevents the adjusting nut 12 from rotating on its own, improving the stability and reliability of the pipeline fixation, but also allows for forward and reverse rotation adjustment of the adjusting nut 12, avoiding the inability to adjust the position of the adjusting rod 2. The operation is simple and convenient, and it has good practicality.

[0025] Two symmetrically distributed, T-shaped sliders 27 are provided on the convex ring 16. The sliders 27 are slidably mounted on the frame 14. The sliders 27 can guide the movement of the insert rod 15 and the collar 19, which can prevent the spring 17 from twisting and affecting its service life, and ensure that the pin 20 and the insert rod 15 can be stably inserted into the positioning hole 21 and the groove. Example 2

[0026] like Figure 1 As shown in the figure, this embodiment proposes an auxiliary mechanism for connecting air conditioning refrigeration pipes. Compared with the first embodiment, in this embodiment, the adjusting rod 2 is provided with a clamping assembly. The clamping assembly includes a connector 3 provided on the adjusting rod 2, a fixing ring 4 with an elastic anti-slip pad 10, a connecting plate 5 provided on the fixing ring 4, a second bolt 8 passing through the fixing ring 4, and a second nut 9 threadedly connected to the second bolt 8. A first bolt 6 is provided through the connector 3 and the connecting plate 5, and a first nut 7 is threadedly connected to the first bolt 6. When it is necessary to clamp and fix the pipe, the pipe is first passed through the fixing ring 4, and then the opening of the fixing ring 4 is gradually closed by rotating the second bolt 8 and the second nut 9 until the elastic anti-slip pad 10 squeezes and fixes the pipe. At the same time, the first bolt 6 and the first nut 7 are used to fix the connector 3 and the connecting plate 5, thereby realizing the limiting and fixing of the refrigeration pipe, preventing the pipe from moving during the operation of the air conditioner, and helping to avoid damage to the pipe.

[0027] The fixed cylinder 1 is provided with a mounting plate 25, and the mounting plate 25 is provided with multiple annularly distributed fourth bolts 26. The entire connecting auxiliary mechanism can be fixed in the required position by the mounting plate 25 and the fourth bolts 26. Example 3

[0028] like Figure 2 , Figure 3 and Figure 5 As shown in the figure, the air conditioning refrigeration pipe connection auxiliary mechanism proposed in this embodiment, compared with the first embodiment, has a detachable protective cover 22 on the mounting ring 11. The protective cover 22 and the adjusting nut 12 abut against each other. Six third bolts 24 are threaded through the mounting ring 11 and connected to the protective cover 22. A plug ring 23 is coaxially provided on the protective cover 22. The adjusting nut 12 is provided with an annular groove that matches the plug ring 23. After the distance of the extension and retraction of the adjusting rod 2 is adjusted, the protective cover 22 is pressed tightly onto the adjusting nut 12 by the third bolts 24. The plug ring 23 and the sliding groove ensure the abutment effect of the protective cover 22 on the adjusting nut 12. The operation is simple and convenient.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
