Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment, and more particularly to a foldable corner protector. Background Art

[0002] Corner protectors are a crucial support structure, widely used in the packaging and transportation of various products. They are primarily used to support flat or planar products, particularly those stacked and transported over long distances. Their primary function is to strengthen and protect the corners of products, preventing damage from collisions and crushing during transportation and handling. By using corner protectors, companies can ensure product integrity and safety, reducing losses resulting from damage.

[0003] In the prior art, packaging corner protectors are usually connected by gluing them together. The corner protectors are installed by gluing double-sided tape at right-angle corners and buckling the arc corners at the four corners of the carton. However, when the corner protectors are connected by double-sided tape, they are difficult to remove due to the certain adhesion of the double-sided tape, and the carton will be damaged, which is not conducive to reuse. Therefore, we propose a foldable corner protector. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1 and Figure 2 As shown, a foldable corner guard comprises a connecting plate 1, an outer wall of the connecting plate 1 is provided with a mounting hole 2, the mounting hole 2 is slidably connected to two sliders 3, the inner walls of the two sliders 3 are rotatably connected to a rotating sleeve 4, the outer walls of the two rotating sleeves 4 are fixedly connected to connecting arms 5, the outer walls of the two connecting arms 5 are fixedly connected to corner guards 16, the direction of the corner guard 16 can be adjusted and fixed according to actual needs, so that the corner guard 16 can adapt to the corner position of the packaging box or fit tightly between two adjacent packaging boxes, the outer wall of the connecting plate 1 is fixedly connected to two fixing blocks 13, an adjusting screw 14 is rotatably connected between the two fixing blocks 13, the outer wall of the adjusting screw 14 is fixedly connected to a knob 15, the inner walls of the two rotating sleeves 4 are rotatably connected to a connecting shaft 12, and both ends of the adjusting screw 14 respectively pass through the connecting shaft 12 and are threadedly connected thereto;

[0023] By adjusting the threaded connection between the screw 14 and the connecting shaft 12, the distance between the two corner guards 16 can be easily adjusted, so that the corner guard 16 can be adapted to the use of boxes of different sizes, providing greater flexibility and applicability of use; the design of the adjusting screw 14 combined with the knob 15 allows the user to easily rotate the adjusting screw 14, and the corner guard 16 can remain stable through the tightness of the threaded connection.

[0024] like Figure 3As shown, the outer walls of the two rotating sleeves 4 are fixedly connected with a clamping block 6, the outer walls of the two sliders 3 are fixedly connected with a rotating shaft 7, the outer walls of the two rotating shafts 7 are sleeved with a torsion spring 8, one end of the torsion spring 8 is fixedly connected to the limit sleeve 9, and the other end of the torsion spring 8 is fixedly connected to the first limit block 10, the outer walls of the two rotating shafts 7 are rotatably connected with the first limit block 10, the outer walls of the two rotating shafts 7 are fixedly connected with the limit sleeve 9, and the outer walls of the two sliders 3 are fixedly connected with a stopper 11; when the clamping block 6 rotates to above the first limit block 10, the first limit block 10 blocks the clamping block 6, thereby limiting the range of motion of the connecting arm 5, thereby facilitating the folding of the connecting arm 5.

[0025] The corner protector 16 is connected to the slider 3 and the connecting plate 1 through the connecting arm 5 and the rotating sleeve 4. The components can rotate relative to each other, so the corner protector 16 can be easily folded up, reducing the volume and making it easy to carry and store.

[0026] like Figure 1 and Figure 4 As shown, the inner walls of the two corner guards 16 are provided with a limiting groove 20, and the outer walls of the two corner guards 16 are provided with an installation groove 21. The inner wall of the installation groove 21 is slidably connected to a connecting plate 22, the bottom of the connecting plate 22 is fixedly connected to a cross block 24, and the top of the connecting plate 22 is fixedly connected to a threaded column 23. It also includes a rubber pad 17, and the bottom of the rubber pad 17 is fixedly connected to a second limiting block 18. The bottom of the second limiting block 18 is snap-fitted with the inner wall of the limiting groove 20, and the bottom of the second limiting block 18 is provided with a threaded hole 19. The threaded column 23 passes through the corner guard 16 and is threadedly connected to the threaded hole 19.

[0027] Working principle: By folding the two connecting arms 5 respectively, when the connecting arms 5 rotate, they respectively drive the rotating sleeve 4 to rotate, and when the rotating sleeve 4 rotates, it drives the clamping block 6 to rotate, and the clamping block 6 squeezes the first limit block 10 until the clamping block 6 is separated from the top of the first limit block 10, until the two connecting arms 5 are rotated to be parallel to the connecting plate 1;

[0028] The corner protectors 16 are clamped at the corners of the packaging box, and the adjusting screw 14 is rotated by turning the knob 15. At this time, the two connecting shafts 12 respectively drive the rotating sleeve 4 to move, and the rotating sleeve 4 drives the slider 3 to slide along the inner wall of the connecting plate 1. At this time, the two connecting arms 5 respectively pull the corner protectors 16, so that the corner protectors 16 are tightly clamped at the corners of the carton;

[0029] When disassembling, the knob 15 is rotated in the opposite direction so that the two corner protectors 16 are released from squeezing the corners of the carton. By folding the connecting arm 5, the clamping block 6 on the rotating sleeve 4 is squeezed against the first limiting block 10 in the opposite direction. The clamping block 6 is limited by the first limiting block 10, thereby facilitating the storage of the device.

[0030] By rotating the cross block 24 , the threaded column 23 is screwed out from the threaded hole 19 on the second limiting block 18 , thereby facilitating the operator to replace and install the rubber pad 17 .

[0031] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.
