Description

Technical Field

[0001] This utility model relates to the field of handle technology, specifically a reinforcing strap fixing structure for non-woven handles of corrugated cardboard packaging boxes. Background Technology

[0002] Corrugated paper packaging products have extremely wide applications, including food and beverage, daily chemical, electronics, home appliances, e-commerce and express delivery. As a necessity for national consumption, its market demand continues to be strong. With the rapid development of the domestic express delivery and e-commerce industry, the corrugated paper packaging market has also ushered in unprecedented growth opportunities. In order to improve the customer's experience when using corrugated paper packaging boxes, some packaging boxes are designed with handles to facilitate consumers' handling.

[0003] However, most packaging boxes on the market currently use a process of drilling holes in the box body and then inserting plastic handles. These plastic handles are not only difficult to degrade, causing long-term pollution to the environment, but their tensile strength is also greatly affected by the external temperature, making them more prone to breakage, especially in cold winters. In addition, cardboard boxes with plastic handles are not easy to stack, take up a lot of space, increase logistics costs, and have a significant impact on the environment. On the other hand, when using non-woven fabric for handles, the adhesion is usually poor, and problems such as glue separation and breakage are easy to occur, affecting the user experience.

[0004] To address this, a reinforcing strap fixing structure for nonwoven handles of corrugated cardboard packaging boxes is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a reinforcing strap fixing structure for non-woven fabric handles of corrugated cardboard packaging boxes.

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

[0007] A reinforcing strap fixing structure for a non-woven fabric handle of a corrugated cardboard packaging box includes: a corrugated cardboard packaging box, a mounting plate at the top of the corrugated cardboard packaging box, a non-woven fabric handle at the top of the mounting plate, a reinforcing fixing component at the bottom of the mounting plate, the reinforcing fixing component including reinforcing connecting plates evenly fixedly installed on both sides of the bottom end of the mounting plate, the bottom wall of the reinforcing connecting plates being on the same horizontal plane as the bottom wall of the mounting plate, a plurality of limiting holes evenly opened at the bottom end of the mounting plate, and a detachable component at the top of the mounting plate.

[0008] Preferably, the mounting plate and the reinforcing connecting plate are attached to the corrugated cardboard box using hot melt adhesive.

[0009] Preferably, the limiting hole is tapered, and multiple limiting blocks are uniformly fixedly installed on the inner wall of the limiting hole.

[0010] Preferably, the detachable component includes mounting bases fixedly installed on both sides of the top of the mounting plate. The mounting bases have grooves inside, and the top of the mounting bases has slots and openings that communicate with the grooves. Both ends of the non-woven handle are fixedly installed with locking blocks. The top of the locking blocks has threaded holes symmetrically opened, and fastening bolts are helically installed in the threaded holes.

[0011] Preferably, the slot is adapted to the size of the card block.

[0012] Preferably, the opening groove is adapted to the size of the nonwoven fabric handle.

[0013] Preferably, the top of the mounting base has symmetrical through holes, and the bottom end of the fastening bolt passes through the through holes and is helically mounted in the threaded hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By setting up reinforced fixing components, after hot melt adhesive is evenly applied to the mounting plate and the reinforcing connecting plate, the mounting plate is then placed on the corrugated cardboard box. The reinforcing connecting plate can increase the contact area between the mounting plate and the corrugated cardboard box, and the tapered limiting hole and limiting block at the bottom of the mounting plate can further increase the contact area between the mounting plate and the corrugated cardboard box, thereby improving the connection stability between the mounting plate and the corrugated cardboard box and facilitating the use of non-woven handles.

[0016] 2. By incorporating a detachable component, the locking block can be inserted into the slide groove along the slot. Once the locking block slides to the inside of the slide groove, the fastening bolt is inserted into the through hole, and then rotated clockwise. The fastening bolt continuously embeds itself into the threaded hole, securing the locking block within the slide groove and fixing the non-woven handle. Similarly, when the user rotates the fastening bolt counterclockwise, the bolt slides out of the threaded hole. The user can then slide the locking block to the slot and remove it from the slide groove, thus disassembling the non-woven handle. This allows the non-woven handle to be reused, reducing material waste and saving on operating costs. Attached Figure Description
