Description

Technical Field

[0001] The utility model belongs to the technical field of plastic bags, and more specifically, particularly relates to a plastic bag with an improved structure. Background Art

[0002] Tape is an indispensable item in people's daily life. According to its function, tape can be divided into: high-temperature tape, double-sided tape, insulating tape, special tape, pressure-sensitive tape, and die-cut tape. Different functions are suitable for different industry needs. A layer of adhesive is coated on the surface of the tape to enable the tape to stick to objects. The earliest adhesives came from animals and plants.

[0003] Based on the above, the inventors have found the following problems: the current adhesive tape is basically a tape body wrapped around a circular tape support ring, which is difficult to find a tearing edge when using it and is not easy to tear off. When the tape is used to seal a box, additional tools are required to open the box and tear off the tape, which increases the inconvenience of use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a plastic bag with improved structure is provided, so as to achieve the purpose of having more practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a plastic bag with improved structure to solve the current ZZ problem.

[0007] A plastic bag with an improved structure comprises a mounting tube, wherein the outer sleeve of the mounting tube is provided with a tape roll, the inner portion of the tape roll is provided with a mounting groove, and the mounting tube is placed inside the mounting groove, a tape strip is provided on one side of the tape roll, and mounting frames are installed on both the inner side of the mounting tube and the outer side of the tape roll, a fixing plate is clamped and installed between the tops of a pair of the mounting frames, a bottom plate is connected between the bottoms of the pair of the mounting frames, the tape strip passes through the pair of mounting frames and extends to the outside, a cutting mechanism is provided inside one of the mounting frames, and the cutting mechanism includes a cutting blade.

[0008] Furthermore, a pair of plug blocks are installed on both sides of the bottom of the fixing plate, and a pair of slots are provided at one end of the inner part of a pair of mounting frames, and the plug blocks and the slots are engaged with each other.

[0009] Furthermore, a through hole is provided on one side of a pair of mounting frames, and a threaded rod is connected to the internal thread of the through hole, one end of the threaded rod passes through a pair of plug blocks and extends to the outside, and a fixing bolt is connected to the external thread of the threaded rod.

[0010] Furthermore, a slide groove is provided inside one of the mounting frames, and a pair of slide rods are installed inside the slide groove, and a movable handle is slidably installed outside the pair of slide rods, and both sides of the movable handle extend to the outside of the slide groove.

[0011] Furthermore, a spring is sleeved on the outside of the pair of sliding rods, and one end of the pair of springs is connected to the moving handle, and a cutting blade (2012) is installed on the side of the moving handle close to the tape roll.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The plastic bag with improved structure is used in coordination with the fixing plate, the mounting frame, the plug block, the slot, the through hole, the threaded rod, the fixing bolt, the slide groove, the slide rod, the moving handle and the cutting blade. When the tape roll needs to be used, the tape strip is pulled out from the inside of the mounting frame. After the required length is pulled out, the tape strip is stuck to the required object. The user pulls the moving handle downward in the slide groove, the moving handle moves on a pair of slide rods, the cutting blade cuts the tape strip, and then pulls the tape strip to separate a part of the tape strip from the tape roll. After that, the moving handle is released, and a pair of springs drive the moving handle to return to the original position for further use. When the tape roll is used up, the pair of fixing bolts can be rotated to separate the fixing bolts from the threaded rod, so that the plug block and the slot are separated from each other, the fixing plate can be removed, and the mounting frame can be taken out, so that the mounting frame can be reused. The utility model has simple and reasonable structure, novel design, simple and convenient operation, can effectively tear off the tape, improves the convenience of use, and has high practical value.
