[0002] A rolling bearing is a precision mechanical component that converts the sliding friction between a rotating shaft and its housing into rolling friction, thereby reducing wear. A rolling bearing consists of an inner ring, an outer ring, rolling elements, and a cage. Based on the type of rolling element, it can be divided into ball bearings and roller bearings, with roller bearings further divided into cylindrical roller bearings and tapered roller bearings.

[0003] To facilitate the centralized transportation of the rolling elements of roller bearings, they are systematically packed into tubular packaging formed by film rolls before leaving the factory, as disclosed in existing patent CN202211129339.2, which describes a heat-sealing device, packaging mechanism, and method for packaging bearing rollers using film rolls. After tapered rollers are packaged in tubular packaging, they are generally transferred and transported using boxes. However, many boxes lack internal positioning measures for the tubular packaging. Although simple wrapping is used for the tubular packaging, this leads to the product becoming scattered after transportation, and the center of gravity of the entire box is unstable, making unloading difficult.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Examples, such as Figures 1-4 As shown, this utility model provides a packaging protection device for conical rollers after they have passed through a tube. It includes a square packaging box 1, a top cover 2, a pad 3 at the bottom, and a steel strip 4 around the side of the box 1. The steel strip 4 has multiple pairs of threading holes 5 for lifting. The top cover 2 closes the top opening of the packaging box 1, and the pad 3 provides space for forklifts to engage, facilitating forklift handling. The steel strip 4 improves the overall reliability of the packaging box 1 and provides the threading holes 5 as insertion points for lifting straps, thus enhancing the overall stability of the device during lifting.

[0023] Furthermore, the packaging box 1 provided by this utility model has a positioning component 6 located in the middle of its interior. The positioning component 6 includes a positioning cylinder 61, which has two rounded heads 611. A transition portion 612, which is concave towards the center of the positioning cylinder 61, is provided between the two rounded heads 611. A pair of positioning bolts 62, which pass through the positioning cylinder 61 from top to bottom and connect to the bottom surface of the packaging box 1, are provided on the rounded heads 611. The positioning cylinder 61, which is similar to a dumbbell shape formed by the rounded heads 611 and the transition portion 612, is similar to the middle shape of the coiled conduit. It can fill the center of the coiled conduit, positioning the conduit and preventing the conduit from becoming too loose from multiple curved surfaces. The positioning bolts 62 are used to reliably fix the positioning cylinder 61 in the packaging box 1 and can be detached, which helps to improve the recycling rate of the positioning component 6.

[0024] To improve the practicality of the positioning cylinder 61, the positioning cylinder 61 provided by this utility model has a hollow structure and adopts a design that allows for detachment of the upper and lower parts. For example, the positioning cylinder 61 includes an upper cylinder 613 and a lower cylinder 614. The top edge of the lower cylinder 614 is provided with a retaining edge 615, which is nested and fitted with the inner wall of the upper cylinder 613. The hollow design of the positioning cylinder 61 helps to reduce the overall weight of the packaging box 1, allowing the positioning cylinder 61 to mainly perform the function of positioning the coiled conduit. The positioning cylinder 61 adopts a bolt-on detachable installation design, and the upper cylinder 613 and lower cylinder 614 can be selected and matched according to the actual height of the packaging box 1. For example, the upper cylinder 613 can be replaced with a taller or shorter specification to meet the needs of different packaging boxes 1. At the same time, the nesting method of the retaining edge 615 with the upper cylinder 613 can improve the reliability of the overall shape of the upper cylinder 613 and lower cylinder 614, which is conducive to ensuring its limiting effect on the conduit.

[0025] To improve the compression resistance of the bottom surface of the lower cylinder 614, the lower cylinder 614 provided by this utility model is provided with a pair of positioning tubes 616 for passing through the positioning bolts 62. The positioning tubes 616 and the lower part of the positioning bolts 62 can form a certain nesting depth, which reduces the horizontal pressure and shear force between the bottom surface of the lower cylinder 614 and the surface of the positioning bolts 62, and helps to extend the actual service life of the lower cylinder 614.

[0026] Since the coiled conduit has a curved surface near the corner of the packaging box 1, a certain gap will be generated. In order to improve the positioning performance of this device, the top of the upper cylinder 613 provided by this utility model is provided with a pair of elastic limiting members 63 corresponding to the positioning bolts 62. The ends of the elastic limiting members 63 extend towards the side edge of the packaging box 1. The elastic limiting members 63 are inserted into the gap between the conduit and the corner of the packaging box 1, and their elasticity is used to buffer and protect the conduit.

[0027] Specifically, the elastic limiting member 63 provided by this utility model includes a top V-shaped plate 631. The top V-shaped plate 631 is provided with a connecting hole 632 that mates with a positioning bolt 62. Both ends of the top V-shaped plate 631 extend toward the side edges of the packaging box 1. A vertical part 633 is provided at the end of the top V-shaped plate 631. A pressure plate 634 extending obliquely toward the positioning cylinder 61 is provided at the bottom of the vertical part 633. The upper half of the pressure plate 634 is a free end. The top V-shaped plate 631 provides a base for extending to both corners of the packaging box 1 simultaneously. The vertical part 633 and the pressure plate 634 are used to insert into the gap between the conduit and the corner of the packaging box 1. The pressure plate 634 contacts the conduit to provide a buffering effect.

[0028] In order to increase the contact span between the pressure plate 634 and the tube, the pressure plate 634 provided by this utility model includes two L-shaped portions 6341 distributed in a V-shape. The L-shaped openings of the L-shaped portions face the packaged item located inside the packaging box 1. The two open L-shaped openings can form two lines of contact with the tube in different directions, which is beneficial for the elastic limiting member 63 to support the tube from multiple directions.

[0029] To improve the installation stability of the elastic limiting member 63, this invention provides a positioning plate 617 around the top edge of the upper cylinder 613. The positioning plate 617 has two pairs of positioning holes 618, which cooperate with the top V-shaped plate 631. Using the two positioning holes 618 and one connecting hole 632, a triangular support can be established horizontally for the top of the elastic limiting member 63, thereby improving the reliability of the elastic limiting member 63. Furthermore, the elastic limiting member 63 can also support and hold additional fillers such as foam plastic materials inside the packaging box 1, further improving the stability of all structures and items inside the packaging box 1.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
