Description

Technical Field

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

[0002] There is no locking sleeve on the mouth of a conventional solar water heater, so polyurethane foam is used to fix the collector tube. The polyurethane foam layer is exposed to the air and is easily infiltrated with water and dust, which affects the insulation and lifespan. The old-style solar foaming requires manual installation of an iron plug, which must be removed after foaming. The foaming process is very labor-intensive and wastes polyurethane insulation materials, because the iron plug will produce scratches after long-term use, and the foaming material will squeeze out the polyurethane insulation material, which is very troublesome and the cost will be greatly increased. For this reason, we have proposed a solar tube locking sleeve. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a solar tube lock heat sleeve, comprising a sleeve body and a connecting sleeve;

[0005] The inner cavity of the sleeve is hollow and cylindrical, a limit ring is arranged on the top of the sleeve, a clamping ring is arranged on the upper outer part of the sleeve, and clamping buckles are arranged equidistantly on the clamping ring, and there are six clamping buckles arranged in a ring shape;

[0006] A connecting sleeve is provided at the bottom of the sleeve body, a leakage hole is provided in the middle of the connecting sleeve, a mounting groove is provided inwardly at the bottom of the sleeve body, metal plates are provided on the inner and outer walls of the mounting groove, and an internal thread is provided on the inner wall of the outer metal plate, and a mounting ring is provided on the top of the connecting sleeve extending upward.

[0007] Preferably, the snap-fit ​​buckles all protrude outwards, and the protruding distance is 3-4 mm, and the snap-fit ​​buckles and the sleeve body are both made of ABS plastic.

[0008] Preferably, the leakage hole is upwardly communicated with the inner cavity of the sleeve body, and the mounting ring surrounds the outer side of the leakage hole.

[0009] Preferably, the mounting ring is a metal ring, and the height of the upward extension is one third of the height of the sleeve body.

[0010] Preferably, the outer side wall of the mounting ring is provided with an external thread, and the mounting ring is screwed upward into the mounting groove, and the connecting sleeve is fixed to the sleeve body through the mounting ring.

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

[0012] This solution uses ABS material for both the sleeve and the connecting sleeve, which has good corrosion resistance and can withstand erosion by water, inorganic salts, alkali alcohols or acids and alkalis, so that the sleeve can have a longer service life; at the same time, installation and disassembly are more convenient and flexible. The sleeve and the connecting sleeve are fixed to each other by threads. In addition to the function of screw fixing, the mounting ring and the mounting groove also have the function of stabilizing the appearance. When used in high temperature conditions, they can prevent deformation and prevent the fixed parts from falling off, which is very convenient and easy. BRIEF DESCRIPTION OF THE DRAWINGS

[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 1-4 The utility model provides a technical solution for a solar tube lock heat sleeve: comprising a sleeve body 1 and a connecting sleeve 2; the inner cavity of the sleeve body 1 is hollow, and the sleeve body 1 is cylindrical, a limiting ring is arranged on the top of the sleeve body 1, a clamping ring 3 is arranged on the upper outer part of the sleeve body 1, and clamping buckles 4 are arranged equidistantly on the clamping ring 3, and there are six clamping buckles 4 arranged in a ring shape;

[0022] Furthermore, a connecting sleeve 2 is provided at the bottom of the sleeve body 1, a leak hole 5 is provided in the middle of the connecting sleeve 2, a mounting groove 6 is provided inwardly from the bottom of the sleeve body 1, metal plates are provided on the inner and outer walls of the mounting groove 6, and an internal thread is provided on the inner wall of the outer metal plate, and a mounting ring 7 is provided on the top of the connecting sleeve 2 extending upward;

[0023] Furthermore, the snap-fit ​​buckles 4 all protrude outwards, and the protruding distance is 3-4 mm, and the snap-fit ​​buckles 4 and the sleeve body 1 are both made of ABS plastic;

[0024] Furthermore, the leakage hole 5 is upwardly connected to the inner cavity of the casing 1, and the mounting ring 7 surrounds the outer side of the leakage hole 5;
