Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning installation equipment, in particular to an air-conditioning wall-penetrating sleeve device. Background Art

[0002] The air conditioner is divided into an indoor unit and an outdoor unit. There are three pipes connecting the indoor unit and the outdoor unit, namely the refrigerant pipe, the condenser pipe and the evaporator pipe. The refrigerant pipe is mainly used to transport the refrigerant, and sends the refrigerant from the condenser to the evaporator to complete the air conditioning refrigeration cycle. The refrigerant pipe is generally made of copper pipes or aluminum pipes, which are widely used because of their good thermal conductivity. The condenser pipe is used to transfer the refrigerant from the indoor unit to the outdoor unit for condensation and dissipate the heat to the outside. The condenser pipe uses a larger diameter copper pipe to ensure that the refrigerant can flow quickly and achieve efficient heat dissipation. The evaporator pipe transfers the refrigerant from the outdoor unit to the indoor unit for evaporation, cooling the air. The evaporator pipe uses a slender copper pipe or aluminum pipe to increase the pipe surface area and heat exchange effect, thereby improving the cooling effect.

[0003] Before installing the outdoor unit and the indoor unit, the three pipes are first wrapped with thermal insulation cotton, and then the outside is fixed with tape to form a whole, and then the pipes are inserted into the reserved air conditioning holes in the wall. Since the pipes are metal pipes, the degree of deformation is low. In addition, the wall has a certain thickness and the air conditioning holes have a large depth. Therefore, when inserting the pipes, the internal resistance of the air conditioning holes is relatively large. At the same time, the edge of the air conditioning holes is chamfered, which easily causes the thermal insulation cotton to break when inserting the pipes. Therefore, the utility model prepares an air conditioning connection pipe insertion device for smoothly passing through the pipes while reducing the risk of damage to the pipes and air conditioning holes. Utility Model Content

[0004] The purpose of the utility model is to provide an air-conditioning wall-penetrating sleeve device and to prepare an air-conditioning connecting pipe penetration device for smoothly passing through the pipe while reducing the risk of damage to the pipe and the air-conditioning hole.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] An air-conditioning wall-penetrating sleeve device comprises a sleeve sleeved on an inner tube of an air-conditioning hole, the sleeve being inserted into and fixed by the end of the inner tube, the sleeve end having a flange ring for limiting the installation position of the sleeve, a plurality of spring pieces being fixed on the end face of the flange ring, one side of the spring piece fixing the flange ring, and the other side being provided with a roller, the spring pieces being distributed in an annular manner on the flange ring, and the roller being rotatably matched with the end side of the corresponding spring piece.

[0007] Furthermore, the sleeve is detachably installed, and is composed of two symmetrically arranged segments, which are assembled into a complete sleeve, and the two segments are fixed by bolts on the corresponding flange ring sides. The flange ring sides corresponding to the two segments are fixed with connecting plates, and the connecting plate corresponding to one segment is provided with a screw hole, and the connecting plate corresponding to the other segment is provided with a limiting hole, and the limiting hole is aligned with the screw hole, and a bolt is provided, one end of the bolt is rotatably installed with the limiting hole, and the other end passes through the screw hole and is threadedly engaged with the screw hole. The middle part of the bolt is a hexagonal column structure.

[0008] Furthermore, the spring sheet is an arc-shaped structure. The spring sheet has side walls on both sides, the side walls are provided with notches, and the side walls are provided with shaft holes for the roller shaft of the roller wheel to be sleeved, so as to allow the roller shaft to be sleeved and rotated after being sleeved.

[0009] The utility model has the following beneficial effects: in the utility model, the roller is fixed by installing the sleeve on the inner tube, the rollers are densely arranged on the corresponding port side of the sleeve, the rollers are in front contact with the air-conditioning pipeline, and when the pipe is penetrated, the outer wall of the pipeline contacts the rollers. The rotation of the rollers allows a smooth transition when the pipeline is expanded and contracted in the inner tube, thereby reducing the difficulty of pipe penetration and preventing the problem of damage caused by the rigid contact between the thermal insulation cotton on the outside of the pipeline and the pipe mouth side of the inner tube.

[0010] At the same time, the roller and the flange ring are installed by means of spring plates. The spring plates are elastic. When the pipeline is twisted in a large range, the spring plates can be slightly deformed to play a certain buffering role and meet the needs of pipeline deformation.

[0018] In the utility model, rollers are fixed by installing a sleeve in an inner tube, and the rollers are densely arranged on the corresponding port side of the sleeve. The rollers are in front contact with the air-conditioning pipeline. When the pipe is penetrated, the outer wall of the pipeline contacts the rollers. The rotation of the rollers allows a smooth transition of the pipeline when it is expanded and contracted in the inner tube, thereby reducing the difficulty of pipe penetration and preventing the problem of damage caused by the rigid contact between the thermal insulation cotton on the outer side of the pipeline and the pipe mouth side of the inner tube.

[0019] At the same time, the roller and the flange ring are installed by means of spring plates. The spring plates are elastic. When the pipeline is twisted in a large range, the spring plates can be slightly deformed to play a certain buffering role and meet the needs of pipeline deformation.
