Description

Technical Field

[0001] The utility model relates to the technical field of solar tube accessories, in particular to a solar tube sealing sleeve. Background Art

[0002] The main function of the solar collector tube is to transport the hot water generated in the vacuum collector tube to the insulation water tank, and at the same time transport the cold water in the insulation water tank to the vacuum collector tube. The connecting pipe acts as a bridge between the insulation water tank and the vacuum collector tube, so that the entire solar water heater system forms a closed loop, so that the solar water heater reaches an optimal working state;

[0003] The existing sealing sleeve used between the solar collector tube and the insulation water tank has many disadvantages. The polyurethane foam layer is exposed to the air and is easy to get into water and dust, affecting the insulation and life. In addition, there will be a certain gap after the installation of the old-fashioned sealing sleeve, which will loosen and fall off. The foaming at the connection part needs to be manually installed with an iron plug, and the iron plug needs to be pulled out after foaming. The foaming process is very troublesome and wastes polyurethane insulation materials. Because the iron plug will produce bumps after long-term use, the foaming material will squeeze out the polyurethane insulation material, which needs to be cleaned manually, greatly increasing the labor cost. Therefore, we propose a solar tube sealing sleeve. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0020] Example:

[0021] See also Figure 1-4The utility model provides a technical solution for a solar tube sealing sleeve: comprising a shell 1, the shell 1 is cylindrical, and a mounting groove 5 is provided in the middle of the shell 1;

[0022] Furthermore, a first hoop 2 is provided on the top of the shell 1, and the first hoop 2 surrounds the outer side of the shell 1;

[0023] Furthermore, a second hoop 3 is provided on the upper outer portion of the housing 1 , and the diameter of the second hoop 3 is one fifth of the diameter of the first hoop 2 ;

[0024] Furthermore, buckles 4 are equidistantly arranged on the second hoop 3, the buckles 4 protrude outward, and a base 6 is arranged at the bottom of the housing 1, and the base 6 is arranged upward at the bottom of the inner cavity of the mounting groove 5;

[0025] Furthermore, a circular hole 7 is formed in the middle of the base 6. The diameter of the circular hole 7 is three-fifths of the diameter of the base 6 and is upwardly connected to the mounting groove 5.

[0026] Furthermore, the inner cavities of the first hoop 2 and the base 6 are both provided with reserved cavities, and the reserved cavities are both provided with lining layers 8, and the lining layers 8 are metal support mesh layers;

[0027] Furthermore, the sealing sleeve used on the conventional solar water heater has many disadvantages. The polyurethane foam layer is exposed to the air and is easy to get into water and dust, which affects the insulation and life. In addition, there will be a certain gap after the old-fashioned sealing sleeve is installed, and it will become loose and fall off. The old-fashioned solar foam needs to be manually installed with an iron plug, and the iron plug needs to be pulled out after the foaming. The foaming process is very troublesome and wastes polyurethane insulation materials. Because the iron plug will produce scratches after long-term use, the foaming material will squeeze out the polyurethane insulation material, and it needs to be cleaned manually, which greatly increases the labor cost.

[0028] Furthermore, the sealing sleeve housing 1 in the present solution is made of ABS plastic, which has good corrosion resistance and can resist corrosion by water, inorganic salts, alkali alcohols or acids and alkalis for a long life; at the same time, a second hoop 3 is provided on the upper part of the housing 1, and buckles 4 are arranged on the second hoop 3. The buckles 4 are also made of ABS plastic and protrude outward. A snap groove is provided at the installation groove position of the solar box, which matches the buckle 4. When installing, the housing is inserted downward into the installation groove of the solar box, and then the housing 1 is rotated to limit the buckle 4 in the snap groove. The housing 1 can be prevented from falling outward by the snap limit.

[0029] Furthermore, an inner lining layer 8 is provided in both the first hoop 2 and the base 6. The inner lining layer 8 is a metal support mesh layer, which can increase the overall strength of the top and bottom of the shell 1. Especially in the hot summer season, plastic is prone to softening after high temperature baking. The setting of the inner lining layer 8 can maintain the shape of the shell 1 and extend its service life.
