Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to a multi-purpose double-layer protective film. Background Art

[0002] The function of the protective film is to put a layer of film on the physical objects we want to protect. According to the purpose, the protective film can be divided into digital product protective film, car protective film, household protective film, food preservation protective film, etc.

[0003] When using existing multi-purpose double-layer protective films, staff often wrap them around the surface of the items that need to be protected. However, since the positions of the items are different, when it is necessary to protect items placed on a relatively flat surface, the protective film cannot be used to wrap them. The protective film can only be covered on the items, causing the protective film to easily fall off. In addition, the lack of a breathable structure makes it easier for condensation to form on the inside of the protective film due to water vapor, making it impossible to protect the items normally. Therefore, we propose a multi-purpose double-layer protective film. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art. When the existing multi-purpose double-layer protective film is used, the staff often wraps it on the surface of the object to be protected. However, since the positions of the objects are different, when it is necessary to protect the objects placed on a relatively flat surface, the protective film cannot be used to wrap them. The protective film can only be covered on the objects, causing the protective film to fall off easily. In addition, the lack of a breathable structure makes it easier for condensation water to form on the inside of the protective film due to water vapor, making it impossible to provide normal protection for the objects.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A multi-purpose double-layer protective film includes an upper film, a lower film is bonded to the bottom of the upper film, an adsorption layer is bonded to the outer wall of the lower film, protective layers are bonded to the outer walls of the upper film and the adsorption layer, auxiliary pull strips are provided on the outer wall of the protective layer, the top of the upper film passes through the lower film and the adsorption layer to form an air hole, a number of guide rods are equidistantly arranged on the inner wall of the air hole, and a number of dust-proof hairs are equidistantly arranged on the outer wall of the guide rod.

[0007] As a preferred solution of the present invention, the upper membrane and the lower membrane are both made of polyvinyl chloride.

[0008] The technical effect of adopting the above-mentioned further solution is that the upper and lower films made of polyvinyl chloride material have strong flexibility, high tensile strength and wear resistance, and can protect the objects well.

[0009] As a preferred solution of the present invention, the adsorption layer is made of hot melt adhesive material.

[0010] The technical effect of adopting the above further solution is that the adsorption layer made of hot-melt adhesive material is suitable for occasions requiring rapid bonding, and can be quickly bonded and fixed to the surrounding area, thereby preventing the protective film from falling off.

[0011] As a preferred solution of the present invention, the protective layer is made of polyethylene material, and the auxiliary pull strip is bonded to the protective layer.

[0012] The technical effect of adopting the above-mentioned further scheme is: the protective layer made of polyethylene material has excellent tensile strength and wear resistance, can provide good protection, and has a long service life. The auxiliary pull strip is bonded to the protective layer, so that the staff can tear off the protective layer very conveniently through the auxiliary pull strip.

[0013] As a preferred solution of the present invention, the guide rod is installed toward the top, and the dust-proof fluff is made of organic soft plastic material.

[0014] The technical effect of adopting the above further solution is: by installing the guide rod toward the top, water vapor can be discharged well through the air vents, and the dust-proof fluff made of organic soft plastic material can effectively prevent dust from adhering to the surface of the object through the air vents.

[0015] As a preferred solution of the present invention, a mounting groove is provided on the inner side wall of the air vent corresponding to the guide rod, and the mounting groove is adapted to the guide rod.

[0016] The technical effect of adopting the above further solution is that the guide rod can be installed more conveniently by adapting the installation groove to the guide rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] In the utility model, through the design of the adsorption layer, auxiliary pull strips, air holes and dust-proof fluff, when it is necessary to protect items placed on a relatively flat surface, the staff can tear off the protective layer at the bottom through the auxiliary pull strips, so that the flat surface can be adsorbed and fixed through the adsorption layer. When ventilation is needed, the staff can tear off the protective layer at the top through the auxiliary pull strips, so that the water vapor on the inside of the protective film can be discharged through the air holes, avoiding the formation of condensation water on the inside of the protective film. The operation is relatively simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 1-4 As shown, the utility model provides a technical solution: a multi-purpose double-layer protective film, comprising an upper film 1, a lower film 101 is bonded to the bottom of the upper film 1, an adsorption layer 2 is bonded to the outer wall of the lower film 101, the adsorption layer 2 can adsorb the surface of the placed objects, and a protective layer 3 is bonded to the outer walls of the upper film 1 and the adsorption layer 2, the protective layer 3 can protect the upper film 1 and the adsorption layer 2, an auxiliary pull strip 301 is provided on the outer wall of the protective layer 3, and the protective layer 3 can be torn off through the auxiliary pull strip 301, the top of the upper film 1 passes through the lower film 101 and the adsorption layer 2 to open a ventilation hole 4, the ventilation hole 4 can discharge water vapor, and a number of guide rods 401 are equidistantly arranged on the inner wall of the ventilation hole 4, and a number of dust-proof hairs 402 are equidistantly arranged on the outer wall of the guide rod 401, and the dust-proof hairs 402 can prevent dust from passing through the ventilation hole 4 and protecting the surface of the object. Example 2

[0029] like Figure 1-4 As shown, the upper film 1 and the lower film 101 are both made of polyvinyl chloride. The upper film 1 and the lower film 101 made of polyvinyl chloride have strong flexibility, high tensile strength and wear resistance, and can protect the items well.

[0030] The adsorption layer 2 is made of hot melt adhesive material. The adsorption layer 2 made of hot melt adhesive material is suitable for occasions that require rapid bonding. It can be quickly bonded and fixed to the surrounding area, thereby preventing the protective film from falling off.

[0031] The protective layer 3 is made of polyethylene material, and the auxiliary pull strip 301 is bonded to the protective layer 3. The protective layer 3 made of polyethylene material has excellent tensile strength and wear resistance, can provide good protection, and has a long service life. The auxiliary pull strip 301 is bonded to the protective layer 3, so that the staff can tear off the protective layer 3 very conveniently through the auxiliary pull strip 301.

[0032] The guide rod 401 is installed toward the top, and the dust-proof fluff 402 is made of organic soft plastic material. By installing the guide rod 401 toward the top, water vapor can be discharged well through the air vent 4, and the dust-proof fluff 402 made of organic soft plastic material can effectively prevent dust from adhering to the surface of the object through the air vent 4.

[0033] An installation groove 403 is provided on the inner side wall of the air vent 4 corresponding to the guide rod 401 , and the installation groove 403 is adapted to the guide rod 401 . The adaptation of the installation groove 403 to the guide rod 401 makes it more convenient to install the guide rod 401 .

[0034] The working process of the present invention is as follows: when a multi-purpose double-layer protective film is used to protect items placed on a relatively flat surface, the staff can first tear off the protective layer 3 at the bottom through the auxiliary pull strip 301, so that the adsorption layer 2 can be exposed, and the flat surface can be adsorbed and fixed through the adsorption layer 2 to prevent the protective film from falling off due to external force. When ventilation is required, the staff can tear off the protective layer 3 at the top through the auxiliary pull strip 301, so that the air holes 4 can be exposed to the outside, so that the water vapor inside the protective film can be discharged through the air holes 4, and the dust-proof fluff 402 can effectively prevent dust from entering the inside of the protective film through the air holes 4 and adhering to the surface of the item. Compared with the existing multi-purpose double-layer protective film, it can be more convenient to protect items placed on a relatively flat surface, and the protective film is not easy to fall off after installation, and the water vapor inside can also be discharged well.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
