Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vest bags, and particularly relates to a continuous-roll structure of vest bags. Background Technique
[0002] The vest bag, also known as the carry bag, is a common type of plastic bag. It gets its name because its shape resembles a vest. It can be stored in two ways: stacked or rolled up.
[0003] After the wound vest bag is pulled out and used, the outer bags are prone to looseness and it is difficult to maintain a tightly wound state. It is easy to get messy during the storage process, resulting in a poor stability problem of the conventional continuous-roll structure of vest bags.
[0004] Therefore, we propose a continuous-roll structure of vest bags to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to solve the problem of poor stability of the conventional continuous-roll structure of vest bags, and a continuous-roll structure of vest bags is proposed.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] The continuous-roll structure of vest bags includes a continuous-roll of vest bags. An elastic expansion seat is inserted inside the continuous-roll of vest bags. A bolt is threadedly installed on the side of the elastic expansion seat. The side end of the bolt is in movable contact with the inner wall of the elastic expansion seat. A rotating guide seat is rotatably installed on the upper part of the elastic expansion seat. A sliding seat is slidably installed on the side of the rotating guide seat. A conical spring is connected between the sliding seat and the rotating guide seat. A pressing rod is fixedly connected to the lower end of the sliding seat. First, insert the lower part of the elastic expansion seat into the continuous-roll of vest bags, and then tighten the bolt. Use the bolt to extrude the elastic expansion seat outward, so that the elastic expansion seat is fixed in the continuous-roll of vest bags. Use the elastic force of the conical spring to act on the sliding seat inward, and through the sliding seat to act on the pressing rod inward, so that the pressing rod presses on the outside of the continuous-roll of vest bags to prevent the continuous-roll of vest bags from loosening after use. When the continuous-roll of vest bags becomes thinner after being taken, the conical spring drives the sliding seat to keep the pressing rod tightly pressed, improving the winding stability of the continuous-roll of vest bags during use.
[0008] Preferably, the elastic expansion seat includes a fixed shaft, a retaining disc and a U-shaped elastic seat. The retaining disc is fixedly connected to the upper end of the fixed shaft. The fixed shaft is fixedly connected to the upper end of the U-shaped elastic seat. After the U-shaped elastic seat is extruded by the bolt, the U-shaped elastic seat expands outward, and the lower part of the U-shaped elastic seat is fixed on the continuous-roll of vest bags. Conversely, the U-shaped elastic seat releases the continuous-roll of vest bags, which is convenient for locking or removing the elastic expansion seat.
[0009] Preferably, the elastic expansion seat further includes an anti-slip strip, and the anti-slip strip is fixedly connected to the lower part of the portal elastic seat. The anti-slip strip is used to increase the friction between the continuous roll of vest bags and the elastic expansion seat.
[0010] Preferably, the elastic expansion seat further includes a threaded ring, and the threaded ring is fixedly connected to the outside of the portal elastic seat. The threaded ring is used to increase the threaded connection range between the elastic expansion seat and the bolt.
[0011] Preferably, the rotating guide seat includes a seat body, and a guide groove is formed on the side of the seat body. The guide groove is used to conveniently guide the sliding of the sliding seat.
[0012] Preferably, the bolt includes a knob and a threaded bolt body, and the side end of the knob is fixedly connected to the threaded bolt body. After the threaded bolt body is tightened by the knob, the threaded bolt body acts outward on the inner wall of the portal elastic seat, causing the portal elastic seat to expand outward. Conversely, the portal elastic seat contracts by virtue of the elastic force, which is convenient for controlling the expansion or contraction of the elastic expansion seat.
[0013] Preferably, the pressing rod includes a rod body and saw teeth, and the saw teeth are evenly and fixedly connected to the outside of the rod body. The elastic force of the conical spring acts on the sliding seat, causing the sliding seat to act on the rod body, pressing the rod body outside the continuous roll of vest bags. After pulling out the bags on the continuous roll of vest bags outward and then turning them outward onto the saw teeth, the saw teeth are used to increase the friction on the bags.
[0014] In summary, the technical effects and advantages of the present utility model are as follows:
[0015] 1. First, insert the lower part of the elastic expansion seat into the inside of the continuous roll of vest bags, and then tighten the bolt. The bolt is used to extrude the elastic expansion seat outward, fixing the elastic expansion seat inside the continuous roll of vest bags. The elastic force of the conical spring acts inward on the sliding seat, and through the sliding seat, it acts inward on the pressing rod, pressing the pressing rod outside the continuous roll of vest bags to prevent the continuous roll of vest bags from becoming loose after use. When the continuous roll of vest bags becomes thinner during use, the conical spring drives the sliding seat to keep the pressing rod tightly pressed, improving the winding stability of the continuous roll of vest bags during use.
[0016] 2. After the portal elastic seat is extruded by the bolt, the portal elastic seat expands outward, fixing the lower part of the portal elastic seat on the continuous roll of vest bags. Conversely, the portal elastic seat releases the continuous roll of vest bags, which is convenient for locking or removing the elastic expansion seat.
[0017] 3. After the threaded bolt body is tightened by the knob, the threaded bolt body acts outward on the inner wall of the portal elastic seat, causing the portal elastic seat to expand outward. Conversely, the portal elastic seat contracts by virtue of the elastic force, which is convenient for controlling the expansion or contraction of the elastic expansion seat.
