Description

Technical Field

[0001] This utility model relates to the field of storage sealing technology, specifically to a sealing strip opener / closer. Background Technology

[0002] In daily life, storage supplies are indispensable, helping to improve the utilization of storage space. Heavy clothing and bedding can be packed into compression bags, and the air inside can be extracted to ensure tight contact between the clothing and the bag, minimizing the bag's volume and greatly facilitating storage. Even food can be packed into compression bags. Compression bags are usually sealed with a sealing strip and equipped with a clasp for easy opening and closing. However, some existing sealing strip clasps lack anti-wear structures, causing wear and tear on both the sealing strip and the compression bag after prolonged use. Furthermore, closing the sealing strip requires considerable effort. Therefore, we have proposed a new type of sealing strip clasp. Utility Model Content

[0003] In view of this, the present invention provides a sealing strip opener / closer, which can not only reduce the wear of the sealing strip and the compression bag, but also facilitate the sealing strip to achieve a seal by squeezing it, thus ensuring the convenience of opening and closing the sealing strip.

[0004] To solve the above-mentioned technical problems, this utility model provides a sealing strip opener, including a U-shaped sealing clip that can slide on the sealing strip. Two protrusions that can apply pressure to the sealing strip are symmetrically arranged on opposite surfaces of the U-shaped sealing clip. The protrusions have smooth characteristics, which can not only reduce the wear caused when moving the U-shaped sealing clip, but also facilitate the compression of the sealing strip to achieve a seal.

[0005] The sealing strip is installed on the storage structure, which specifically includes compression bags, storage bags, etc.

[0006] The protrusion is a roller structure, and the roller is mounted on the U-shaped sealing clamp, which changes the contact between the sealing strip and the opener from sliding friction to rolling friction, greatly reducing the wear of the sealing strip and the surface of the compression bag.

[0007] The U-shaped sealing clamp has two symmetrical receiving grooves, with the roller located inside the receiving groove and the rolling surface of the roller protruding from the receiving groove.

[0008] The U-shaped sealing clamp has two symmetrical opening and closing grooves at its open end. These grooves are connected to the side wall of the U-shaped sealing clamp. The gap between the two grooves gradually narrows from the side wall of the U-shaped sealing clamp to the protrusion. The opening and closing grooves have a guiding function, which facilitates the closing and guiding of the sealing strip. When the U-shaped clamp moves along the sealing strip, the rollers roll to reduce resistance. At the same time, the opening and closing grooves guide the sealing strip to automatically align and tighten, reducing the need for manual force.

[0009] The opening and closing groove is arc-shaped, and the arc surface provides a smooth inlet to guide the sealing strip in.

[0010] The U-shaped sealing clip has an opening mechanism inside for opening the sealing strip. The opening mechanism is located on the side of the two protrusions, and the opening mechanism and the opening groove are located on the same side of the U-shaped sealing clip.

[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0012] 1. When this utility model is used, it can not only reduce the wear of the sealing strip and the compression bag, but also facilitate the sealing strip to achieve a seal by squeezing it, thus ensuring the convenience of opening and closing the sealing strip.

[0013] 2. When this utility model is used, the protruding part adopts a smooth roller structure, and the rolling surface protrudes from the receiving groove, so that the contact mode between the sealing strip and the opener is changed from sliding friction to rolling friction, which greatly reduces the wear of the sealing strip and the surface of the compression bag. It is especially suitable for high-frequency opening and closing scenarios, significantly reducing wear and extending service life.

[0014] 3. When this utility model is used, the roller rotation design combined with the guide slope of the opening and closing groove (the gap gradually narrows towards the protrusion) forms a "progressive extrusion". When the U-shaped clamp moves along the sealing strip, the roller rolls to reduce resistance. At the same time, the opening and closing groove guides the sealing strip to automatically align and press, reducing the need for manual force application.

[0015] 4. When this utility model is used, the arc shape of the opening and closing groove and the roller work together to provide a smooth entrance to guide the sealing strip into the groove. The gradually narrowing gap forces the sealing strip to be precisely guided to the pressure point of the protrusion, thus avoiding the problem of local air leakage caused by misalignment of the sealing strip.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] According to embodiments of this utility model, such as Figure 1 As shown: This embodiment provides a sealing strip opener, including a U-shaped sealing clip 100, which can slide on the sealing strip 200. Two protrusions 300 that can apply pressure to the sealing strip 200 are symmetrically arranged on opposite surfaces of the U-shaped sealing clip 100. The protrusions 300 have smooth characteristics. When moving the U-shaped sealing clip 100, it can not only reduce the wear caused, but also facilitate the compression of the sealing strip 200 to achieve a seal, extend the service life, and ensure the convenience of opening and closing the sealing strip 200.

[0024] Furthermore, such as Figure 4 As shown, the sealing strip 200 is set on the storage structure 600, which is specifically a compression bag, storage bag, etc. The sealing strip 200 is glued and fixed to the storage structure 600 by heat pressing.

[0025] Furthermore, such as Figure 2 and Figure 3 As shown, the protrusion 300 is a roller structure. The roller is rotatably mounted on the U-shaped sealing clamp 100, which changes the contact mode between the sealing strip 200 and the opener from sliding friction to rolling friction, greatly reducing the wear of the sealing strip 200 and the surface of the compression bag.

[0026] Furthermore, the U-shaped sealing clamp 100 has two symmetrically arranged receiving grooves, with the roller located inside the receiving groove and the rolling surface of the roller protruding from the receiving groove.

[0027] Furthermore, the U-shaped sealing clamp 100 has two symmetrical opening and closing grooves 500 at its opening. The opening and closing grooves 500 are connected to the side wall of the U-shaped sealing clamp 100. The gap between the two opening and closing grooves 500 gradually narrows from the side wall of the U-shaped sealing clamp 100 to the protrusion 300. The opening and closing grooves 500 have a guiding function, which facilitates the closing guidance of the sealing strip 200. When the U-shaped clamp moves along the sealing strip 200, the roller rolls to reduce resistance. At the same time, the opening and closing grooves 500 guide the sealing strip 200 to automatically align and press, reducing the need for manual force application.

[0028] Furthermore, such as Figure 1 As shown, the opening and closing groove 500 is arc-shaped, and the arc surface provides a smooth inlet to guide the sealing strip 200 into place.

[0029] Furthermore, such as Figure 1 and Figure 2 As shown, the U-shaped sealing clip 100 is provided with an opening structure 400 for opening the sealing strip 200. The opening structure 400 is located on the side of the two protrusions 300, and the opening structure 400 and the opening groove 500 are located on the same side of the U-shaped sealing clip 100.

[0030] It is worth mentioning that, with Figure 1 The U-shaped sealing clip in the 100 is different from that in the 100, such as Figure 5 The U-shaped sealing clip 2100 shown lacks the opening structure 400. When opening the sealing strip 200, it can be opened manually by the operator. When it is necessary to close the sealing strip 200, the method of using the U-shaped sealing clip 2100 is the same as that of the U-shaped sealing clip 1100, which can achieve the sealing effect of closing the sealing strip 200.

[0031] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
