Description

Technical Field

[0001] This utility model relates to the field of air conditioner outdoor unit technology, and in particular to a connecting pipe for air conditioner outdoor units that is easy to replace. Background Technology

[0002] With the continuous advancement of science and technology and the increasing improvement of people's living standards, air conditioners have become one of the most important household appliances in people's daily lives. Currently, the connecting pipes used for indoor and outdoor units of air conditioners are made of plastic pipes. However, plastic pipes are easily damaged after long-term use, and existing devices are inconvenient to replace. For example, China has disclosed "a connecting pipe for indoor and outdoor units of air conditioners," with the application number "CN02250082.0." This structure involves welding a small section of copper connecting pipe to both ends of an aluminum alloy connecting pipe section. This can reduce costs and ensure the reliability of the connection between the connecting pipe and the indoor and outdoor unit connecting valves (or joints). However, it cannot easily and quickly disassemble the pipe, thus failing to simplify the installation and disassembly process and shorten maintenance and replacement time. It also cannot allow for fine-tuning of the pipe's angle and direction, and it cannot absorb some of the vibrations generated by the outdoor unit and pipes. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1 , Figure 2 and, Figure 3 Figure 4 This utility model discloses a replaceable connecting pipe for an air conditioner outdoor unit, comprising: a connecting pipe 1, a groove 2 inside the connecting pipe 1, a mounting plate 3 fixedly connected to the inner surface of the groove 2, a spring 4 fixedly connected to the upper surface of the mounting plate 3, a locking block 5 fixedly connected to the other end of the spring 4, the locking block 5 having inclined rounded corners on both sides, a control rod 6 fixedly connected to the rear surface of the locking block 5, the control rod 6 being movably connected to the mounting plate 3 and the connecting pipe 1, for moving up and down between the mounting plate 3 and the connecting pipe 1, and a handle 15 fixedly connected to the other end of the control rod 6. The connecting pipe 1 is detachably connected to a pipe 7. The pipe 7 is provided with a slot 8, which is movably connected to a block 5. The shape of the slot 8 is the same as the front end of the block 5. A positioning block 16 is fixedly connected to the outer surface of the pipe 7. A positioning hole 17 is provided on the connecting pipe 1, which is movably connected to the positioning block 16 for positioning and installing the pipe 7. A first sealing ring 13 is fixedly connected inside the connecting pipe 1. A second sealing ring 14 is fixedly connected to one end of the pipe 7. The second sealing ring 14 is movably connected to the first sealing ring 13 for sealing. The material of the second sealing ring 14 and the first sealing ring 13 is silicone.

[0024] Specifically, firstly, the pipe 7 is installed in the connecting pipe 1 through the positioning block 16 and the positioning hole 17. The spring 4 in the slot 2 of the connecting pipe 1 applies elastic force to the locking block 5. The pipe 7 is inserted into the connecting pipe 1 by pressing the locking block 5 through the inclined surface of the locking block 5. The position of the pipe 7 is fixed by the locking block 5 in the slot 8. The pipe 7 and the connecting pipe 1 are sealed by the first sealing ring 13 and the second sealing ring 14. When disassembling, the control rod 6 is lifted by the handle 15. The control rod 6 drives the locking block 5 to rise, thereby removing the pipe 7 from the baffle.

[0025] Reference Figure 1 The other end of the pipe 7 is fixedly connected to a flange 9. The outer surface of the flange 9 is fixedly connected to a first fixed pipe 10. The other end of the first fixed pipe 10 is fixedly connected to a metal bellows 11, which is used to provide a steering adjustment angle. The bellows can absorb some of the vibration generated by the outdoor unit and the pipe. The metal bellows 11 is made of aluminum. The other end of the metal bellows 11 is fixedly connected to a second fixed pipe 12.

[0026] Specifically, a metal bellows 11 is installed at one end of the pipe 7. The metal bellows 11 can provide a steering angle adjustment function, and the bellows can absorb some of the vibrations generated by the outdoor unit and the pipe. However, since the adjustability of the metal bellows 11 is relatively difficult to install, a first fixing pipe 10 and a second fixing pipe 12 are installed at both ends of the metal bellows 11. The hardness and rigidity of the first fixing pipe 10 and the second fixing pipe 12 make it easier to install the metal bellows 11.

[0027] Working principle: First, the pipe 7 is positioned and installed in the connecting pipe 1 through the positioning block 16 and positioning hole 17. The pipe 7 squeezes the clamping block 5, so that the clamping block 5 engages with the clamping groove 8. The spring 4 applies elastic force to the clamping block 5 to fix the position of the pipe 7, and seals it through the first sealing ring 13 and the second sealing ring 14. One end of the pipe 7 is connected to the first fixing pipe 10 through the flange 9. The first fixing pipe 10 is connected to the metal corrugated pipe 11, and the installation angle and direction of the metal corrugated pipe 11 can be adjusted.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. 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 utility model.
