Description

Technical Field

[0001] The utility model relates to the technical field of cold-resistant sheaths, in particular to a sheath with flexible and cold-resistant functions. Background Art

[0002] As a commonly used means of transportation in modern times, the main function of a car is to provide space for users to ride. When existing cars are used in winter, it is often necessary to arrange a shield on the outer surface of the car to prevent cold air in the external environment from entering the interior of the car, thereby affecting the subsequent use of the car. However, the existing cover lacks drying auxiliary components. During the use of the cover, it is unable to absorb the water vapor entering the inside of the cover according to the use needs, resulting in water vapor entering the outer surface of the car, causing the outer surface of the car to freeze, thereby affecting the user experience of the car cover.

[0003] Compared with the existing cold-resistant cover, the utility model adds a drying auxiliary component. During the use of the cover, water vapor can be prevented from invading the outer surface of the car and causing ice to form on the outer surface of the car, thereby improving the use experience of the car cover. Utility Model Content

[0004] The purpose of the utility model is to provide a protective sheath with flexible and cold-resistant functions to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solution: comprising a sleeve and a first elastic belt, wherein two groups of first elastic belts are sewn on the outer surface of the sleeve, and a second elastic belt is sewn on the outer surface of the sleeve, and the second elastic belt is located on one side of the first elastic belt.

[0006] Preferably, a first drying layer is sewn on the bottom of the sleeve.

[0007] Preferably, a first thermal insulation layer is sewn on the bottom of the first drying layer.

[0008] Preferably, a reinforcement layer is sewn on the bottom of the first thermal insulation layer.

[0009] Preferably, a second thermal insulation layer is sewn at the bottom of the reinforcement layer.

[0010] Preferably, a second drying layer is sewn on the bottom of the second thermal insulation layer.

[0011] Preferably, an inner lining layer is sewn at the bottom of the second dryness layer.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model is provided with a first drying layer and a second drying layer. When water vapor in the external environment is conducted to the inside of the first drying layer through the top of the jacket, the montmorillonite particles inside the first drying layer absorb the water vapor. When water vapor on the outer surface of the vehicle is conducted to the inside of the second drying layer, the montmorillonite particles inside the second drying layer absorb the water vapor, thereby preventing the water vapor on the outer surface of the vehicle from freezing, thereby improving the user experience of the cold-resistant jacket.

[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] Embodiment 1

[0020] like Figure 1 , Figure 2 and Figure 3As shown, the utility model proposes a protective cover with flexible and cold-resistant functions, including a cover body 1 and a first elastic band 2. Two groups of first elastic bands 2 are sewn on the outer surface of the cover body 1. The cover body 1 provides fixing points for the first elastic band 2, the second elastic band 3 and the first drying layer 4 sewn on its outer surface and bottom. The first elastic band 2 is sewn on the front and back of the cover body 1. When the cover body 1 is put on the outer surface of the car, the first elastic band 2 is tightened to generate a wrapping force on the car, thereby completing the fixation of the cover body 1. The outer surface of the cover body 1 is sewn with a second elastic band 3, and the second elastic band 3 is located on one side of the first elastic band 2. The second elastic band 3 is sewn on both sides of the cover body 1. When the cover body 1 is put on the outer surface of the car, the second elastic band 3 is tightened to generate a wrapping force on the car, thereby completing the fixation of the cover body 1. A first thermal insulation layer 5 is sewn on the bottom of the first drying layer 4. The first thermal insulation layer 5 is made of thermal insulation cotton material. The first thermal insulation layer 5 is sewn with a reinforcing layer 6 at the bottom, which is sewn at the bottom of the first drying layer 4 to block the temperature in the external environment from being conducted to the bottom of the jacket, thereby improving the cold resistance of the jacket. The first thermal insulation layer 5 is sewn with a reinforcing layer 6 at the bottom, which is sewn at the bottom of the first thermal insulation layer 5 to provide a fixing point for the second thermal insulation layer 7 sewn at the bottom thereof. At the same time, because the reinforcing layer 6 is woven with metal wire, the structural strength of the cold-resistant jacket is improved, thereby extending the service life of the cold-resistant jacket. The second thermal insulation layer 7 is sewn at the bottom of the reinforcing layer 6 to provide a fixing point for the inner lining layer 9 sewn at the bottom thereof, thereby preventing the heat on the outer surface of the car from being lost to the external environment through the jacket, thereby improving the cold resistance of the jacket. The second drying layer 8 is sewn with an inner lining layer 9 at the bottom, which is made of cotton cloth to reduce the friction when the jacket contacts the car, thereby providing protection for the car.

[0021] The working principle of a protective cover with flexible and cold-resistant functions based on the first embodiment is: first, the cover body 1 is put on the outer surface of the car, at this time, the first elastic band 2 is tightened to generate a wrapping force on the car, thereby completing the fixation of the cover body 1, and the second elastic band 3 is sewn on both sides of the cover body 1. When the cover body 1 is put on the outer surface of the car, the second elastic band 3 is tightened to generate a wrapping force on the car, thereby completing the fixation of the cover body 1. At this time, the first thermal insulation layer 5 blocks the temperature in the external environment from being conducted to the bottom of the cover, and the second thermal insulation layer 7 prevents the heat on the outer surface of the car from being lost to the external environment through the cover, thereby improving the cold resistance effect of the cover.

[0022] Embodiment 2

[0023] like Figure 3As shown, the utility model proposes a protective cover with flexible and cold-resistant functions. Compared with the first embodiment, this embodiment also includes: a cover body 1 and a first drying layer 4. The first drying layer 4 is sewn on the bottom of the cover body 1. The first drying layer 4 is made of montmorillonite particles wrapped in cotton cloth. When water vapor in the external environment is conducted to the inside of the first drying layer 4 through the top of the cover, the montmorillonite particles inside the first drying layer 4 absorb the water vapor. A second drying layer 8 is sewn on the bottom of the second thermal insulation layer 7. When water vapor on the outer surface of the car is conducted to the inside of the second drying layer 8, the montmorillonite particles inside the second drying layer 8 absorb the water vapor to prevent the water vapor on the outer surface of the car from freezing, thereby improving the use experience of the cold-resistant cover.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
