Description

Technical Field

[0001] This utility model relates to the field of air conditioning copper pipe technology, specifically to an adjustable spacing flexible connection component for air conditioning copper pipes. Background Technology

[0002] Copper pipes are the main connecting tool in air conditioning systems, used to connect the indoor and outdoor units and specifically for transporting refrigerant. If there are gaps in the connection of the copper pipes, it will not only waste refrigerant such as Freon, but also greatly reduce the cooling effect of the air conditioner. Therefore, connecting components are often used to reinforce both ends of the pipes.

[0003] To prevent copper pipes from loosening and leaking, most connecting components are made according to the diameter of the copper pipes. For ease of installation, the pipes used for connection are mostly flexible and can be bent or have their connection direction changed. However, the distance between the connecting components is mostly fixed and cannot be adjusted. If the copper pipes on both sides are close or far apart, it will be difficult to adjust the length of the connecting components.

[0004] Now, a novel adjustable-spacing flexible connection assembly for air conditioning copper pipes is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable spacing flexible connection assembly for air conditioning copper pipes to solve the problem of fixed spacing of connection components mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-spacing air conditioning copper pipe flexible connection assembly, including a left sleeve block, a right sleeve block provided on the right side of the left sleeve block, a flexible hose fixed at the center between the left and right sleeve blocks, a threaded block fixed at the top of the left sleeve block, and a lead screw threadedly connected to the threaded block, a housing fixed at the top of the right sleeve block, a worm gear movably connected between the front and rear of the top of the housing, a worm wheel movably connected between the left and right sides of the bottom of the housing, and a handle movably connected to the rear of the housing, with copper pipes fixed inside both the left and right sleeve blocks.

[0007] As a further technical solution of this utility model, the front end of the swivel is fixedly connected to the worm gear, and the right side of the lead screw is fixedly connected to the worm wheel.

[0008] As a further technical solution of this utility model, the bottom of both the left and right sleeve blocks are fixed with sleeves, and the sleeves are provided with vertical grooves in the interior. A support rod is movably connected in the vertical grooves. A hole is provided between the upper and lower parts of the rear of the vertical grooves. The front end of the sleeve is provided with a slot, and a slider is movably connected in the slot. A positioning block is fixed to the front end of the slider, and a bolt is threaded inside the positioning block. Sleeves are fixed to both sides of the slider.

[0009] As a further technical solution of this utility model, the ferrule is symmetrically attached to both sides of the sleeve surface, and the bolt is embedded in the hole at the rear.

[0010] As a further technical solution of this utility model, the slider slides vertically along the inner wall of the slot, and the rear of the slider is fixedly connected to the support rod.

[0011] As a further technical solution of this utility model, rubber rings are fixed laterally inside the left sleeve block and the right sleeve block, and rubber sleeves are fixed on the outer sides of both the left sleeve block and the right sleeve block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the adjustable spacing air conditioning copper pipe flexible connection assembly not only realizes the adjustment of the distance of the connection assembly and the adjustment of the support height, but also prevents leakage at the connection point;

[0013] (1) By connecting the screw in the threaded block, connect the left sleeve block and the right sleeve block to the copper pipes on both sides respectively. Then hold the copper pipe on the left side and turn the handle at the back of the housing to guide the worm gear inside the housing to mesh and push the worm wheel at the bottom. Then rotate the screw with the worm wheel and adjust the distance between the left sleeve block and the right sleeve block below the threaded block. This will not affect the delivery of refrigerant to the hose and can also lock the spacing.

[0014] (2) By fixing sleeves at the bottom of both the left and right sleeves, the positioning block is moved at the slot at the front end of the sleeve, and the sleeves on both sides slide against the outer wall of the sleeve to adjust the position of the slider in the slot. After aligning the bolt inside the positioning block with the hole on the inside of the vertical groove, the bolt is screwed in backward to lock the slider in the vertical groove. The height of the connecting components on both sides can be adjusted to support the copper tube.

[0015] (3) By fixing rubber sleeves on the outside of both the left and right sleeves, the left and right sleeves are respectively fitted and fixed to the copper pipes on both sides. The inner diameter of the rubber rings inside the two sleeves is slightly smaller than that of the copper pipes. It is necessary to press hard to fit the left and right sleeves onto the outside of the copper pipes. Then, flip the rubber sleeves to wrap and seal the connection between the left and right sleeves and the copper pipes to prevent refrigerant leakage. Attached Figure Description
