Description

Technical Field

[0001] This utility model relates to the field of insulating paper sleeve technology, and in particular to an improved insulating paper sleeve. Background Technology

[0002] A sleeve is a hollow cylindrical paper product, generally used to protect an item by fitting it inside to prevent it from being corroded by the external environment, thereby extending the item's lifespan.

[0003] In the field of insulating paper, sleeves are also needed to protect unused insulating paper and extend its service life. However, existing insulating paper is generally not protected by sleeves; it is usually just stored in paper bags, which does not provide adequate protection.

[0004] Therefore, we propose an improved insulating paper sleeve to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an improved insulating paper sleeve. This sleeve improves upon traditional sleeves by being a reusable sleeve that can be refilled with new insulating paper after use. During use, the insulating paper is embedded inside the sleeve body and completely enclosed for protection. When in use, the rolled-up insulating paper is pulled out from the opening and quickly torn off using a cutting blade. If too much is pulled out, the excess can be rolled back by rotating the winding drum to avoid waste. When not in use, rotating the cutting blade seals the opening, maintaining a relative seal inside. Therefore, this sleeve not only protects the insulating paper but also facilitates its use, achieving multiple benefits and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An improved insulating paper sleeve includes a sleeve body and an insulating paper body. A base is provided at the bottom end of the sleeve body, and a top cover is provided at the upper end of the sleeve body. A rotating handle is provided in the inner wall of the base, and a winding drum is installed at the front end of the rotating handle. A threaded outer wall is also provided at the front end of the base. An opening is provided at the front end of the sleeve body, and a cutting blade is provided in the inner wall of the opening. A movable screw is installed in the inner wall of the top cover.

[0008] In a further embodiment, both ends of the sleeve body are configured as open holes, and each open hole is provided with a threaded inner wall, wherein the threaded inner wall at the lower end is threadedly connected to the threaded outer wall, and the threaded inner wall at the upper end is threadedly connected to the movable screw.

[0009] In a further embodiment, the insulating paper body is wound and mounted on a take-up drum.

[0010] In a further embodiment, an embedding ring is provided on the outer wall of the movable cylinder, and the embedding ring is movably embedded in the upper cover.

[0011] In a further embodiment, the cutting blade is fixedly installed inside the upper cover, and the cutting blade is movably inserted into the interlayer of the inner wall of the sleeve body, moving at the opening.

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

[0013] This invention improves upon traditional insulating paper sleeves by providing a reusable design. After use, new insulating paper can be added. During use, the insulating paper is embedded within the sleeve body, completely encased and protected. The wound insulating paper is pulled out from the opening and quickly torn off using a cutting blade. Excess paper can be rolled back by rotating the winding drum to prevent waste. When not in use, the cutting blade can be rotated to seal the opening, maintaining a relatively airtight seal. Therefore, this sleeve not only protects the insulating paper but also facilitates its use, offering multiple benefits. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 An improved insulating paper sleeve includes a sleeve body 1 and an insulating paper body 2, wherein the insulating paper body 2 is installed in the sleeve body 1. The upper and lower ends of the sleeve body 1 are set to be open, and a top cover 4 and a base 3 are respectively installed thereon.

[0022] The upper cover 4 is used to open the opening 5 and assist in cutting the insulating paper. The upper cover 4 is installed in the inner wall of the upper end of the sleeve body 1 through the movable screw 10 set in the inner wall. Since the movable screw 10 is movably embedded in the upper cover 4 through the embedded ring, the movable screw 10 can rotate the upper cover 4 to connect with the sleeve body 1. After connection, the upper cover 4 can also rotate independently. When the upper cover 4 rotates, the cutting blade 11 is movably inserted into the inner wall of the sleeve body 1 and is also arc-shaped. With the rotation of the upper cover 4, the cutting blade 11 will move in the inner wall of the sleeve body 1. The cutting blade 11 rotates at the opening 5, which can close and open the opening 5. After opening, the insulating paper body 2 can be pulled out from the inside. After reaching the appropriate length, it can be pulled down to contact the cutting blade 11 for cutting.

[0023] The base 3 is installed on the inner threaded wall 9 of the sleeve body 1 via the threaded outer wall 6. The insulating paper body 2 can be installed on the take-up drum 7 after removing the base 3. Then, one end of the insulating paper body 2 can be passed through the opening 5 and pulled for use. During use, when the insulating paper body 2 is pulled out too much, the rotating handle 8 can be turned to drive the take-up drum 7 to rotate, thereby retracting the insulating paper body 2 into the sleeve body 1.

[0024] The working principle of this utility model is as follows: as shown in the figure, it includes a sleeve body 1 and an insulating paper body 2, wherein the insulating paper body 2 is installed in the sleeve body 1. The upper and lower ends of the sleeve body 1 are set to be open, and a top cover 4 and a base 3 are respectively installed thereon.

[0025] The upper cover 4 is used to open the opening 5 and assist in cutting the insulating paper. The upper cover 4 is installed in the inner wall of the upper end of the sleeve body 1 through the movable screw 10 set in the inner wall. Since the movable screw 10 is movably embedded in the upper cover 4 through the embedded ring, the movable screw 10 can rotate the upper cover 4 to connect with the sleeve body 1. After connection, the upper cover 4 can also rotate independently. When the upper cover 4 rotates, the cutting blade 11 is movably inserted into the inner wall of the sleeve body 1 and is also arc-shaped. With the rotation of the upper cover 4, the cutting blade 11 will move in the inner wall of the sleeve body 1. The cutting blade 11 rotates at the opening 5, which can close and open the opening 5. After opening, the insulating paper body 2 can be pulled out from the inside. After reaching the appropriate length, it can be pulled down to contact the cutting blade 11 for cutting.

[0026] The base 3 is installed on the inner threaded wall 9 of the sleeve body 1 via the threaded outer wall 6. The insulating paper body 2 can be installed on the take-up drum 7 after removing the base 3. Then, one end of the insulating paper body 2 can be passed through the opening 5 and pulled for use. During use, when the insulating paper body 2 is pulled out too much, the rotating handle 8 can be turned to drive the take-up drum 7 to rotate, thereby retracting the insulating paper body 2 into the sleeve body 1.
