Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator return pipe positioning, in particular to a refrigerator return pipe positioning device. Background Art

[0002] The refrigerator return air pipe is an important component in the refrigerator refrigeration system. It is mainly responsible for discharging the refrigerant from the condenser and guiding it back to the evaporator for circulation, thereby completing the entire refrigeration cycle. It is a pipeline that returns the refrigerant from the condenser to the compressor. It is used to recover the refrigerant and ensure its normal circulation.

[0003] When positioning the current refrigerator return air duct, the return air duct is usually fixed on the side wall of the refrigerator. However, when fixing return air ducts of different sizes, it is impossible to effectively stabilize the return air ducts of different sizes, which may cause collision and damage to the return air duct. Therefore, we propose a positioning device for the refrigerator return air duct to solve the above problem. Utility Model Content

[0010] In a further embodiment, a mounting plate is fixedly connected to the bottom surface of the other one of the two clamping blocks, and two mounting holes are provided on the front surface of the mounting plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The device cooperates with the support plate, threaded rod, connecting block and threaded hole through the arrangement. The threaded rod can be connected to the threaded hole by rotating the threaded rod, so that the two clamping blocks can be closed. The position of the clamping plate can be changed according to the size of the return air pipe by utilizing the elasticity of the spring through the arrangement of the fixing hole. Return air pipes of different sizes can be fixed by simply adjusting the length of the threaded rod passing through the threaded hole, thereby ensuring the stability of the fixation of the return air pipe.

[0019] See also Figure 1-3 , In the utility model, a positioning device for a refrigerator return air duct comprises two clamping blocks 1, and a semicircular groove 9 is provided on a side surface of the two clamping blocks 1 close to each other, and a group of fixing holes 13 are provided on the inner wall of each semicircular groove 9, and a spring 14 is fixedly connected to the inner wall of each fixing hole 13, and each group of springs 14 is fixedly connected to a connecting column 16 at one end close to each other, and two groups of connecting columns 16 are fixedly connected to a clamping plate 12 at one end close to each other. By utilizing the elasticity of the spring 14, the position of the clamping plate 12 can be changed, so that it can be suitable for the installation and positioning of return air ducts of different sizes. The front side of one of the two clamping blocks 1 is fixedly connected to a support plate 4, and the upper surface of the support plate 4 is rotatably connected to a threaded rod 2. The front side of the other clamping block 1 of the two clamping blocks 1 is fixedly connected to a connecting block 7, and a threaded hole 8 is provided on the upper surface of the connecting block 7, and the threaded hole 8 is adapted to the threaded rod 2, and the threaded hole 8 and the threaded rod 2 are on the same vertical horizontal line, so that the threaded rod 2 and the threaded hole 8 can be connected.

[0020] A group of guide holes 10 are opened on the upper surface of one of the two clamping blocks 1, and the inner wall of each guide hole 10 is slidably connected with a guide rod 5, and the bottom end of each guide rod 5 is connected to the upper surface of the other clamping block 1. By utilizing the cooperation between the guide rod 5 and the guide hole 10, the two clamping blocks 1 can be positioned, thereby ensuring that the two clamping blocks 1 are closed to each other and the return air pipe can be stabilized.

[0021] The top end of each guide rod 5 is fixedly connected to a limiting plate 11 , and the limiting plate 11 can be used to connect the upper clamping block 1 and the guide rod 5 to prevent the upper clamping block 1 and the guide rod 5 from being separated.

[0022] The top end of the threaded rod 2 is fixedly connected with a turning handle 3, and the turning handle 3 is used to facilitate the staff to rotate the threaded rod 2, making the connection between the two clamping blocks 1 more convenient.

[0023] The bottom surface of the other clamping block 1 of the two clamping blocks 1 is fixedly connected to a mounting plate 6, and two mounting holes 15 are provided on the front surface of the mounting plate 6. The cooperation between the mounting plate 6 and the mounting holes 15 facilitates the staff to fix the lower clamping block 1 on the refrigerator.

[0024] The working principle of the utility model is: when in use, first use the cooperation of the mounting plate 6 and the mounting hole 15 to fix the lower clamping block 1 on the refrigerator. When fixing the return air pipe, place the return air pipe on the clamping plate 12 on the lower clamping block 1, and then press the upper clamping block 1 downward until the threaded rod 2 and the threaded hole 8 can be connected. Then rotate the threaded rod 2, the bottom end of the threaded rod 2 will gradually enter the threaded hole 8, and the upper clamping block 1 will also drop. The two clamping plates 12 will gradually contact the return air pipe. As the length of the threaded rod 2 entering the threaded hole 8 becomes longer, the connecting column 16 will compress the spring 14, and the spring 14 will rebound and push the connecting column 16 until the return air pipe is stabilized between the two clamping blocks 1. It can be suitable for return air pipes of different sizes.
