DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] This embodiment discloses a box, and the box in this embodiment is an LED box. Figure 1 As shown, the box body includes a box body 1, and each of the four corners of the box body 1 is provided with an installation area 11, and each installation area 11 is installed with a corner protector 2. It is worth noting that, since the position and rotation of each different corner are different, although the structure of the corner protector 2 in each installation area 11 is consistent, the actual installation of the corner protector 2 in each different installation area 11 is symmetrical, such as vertical symmetry and left-right symmetry.

[0027] like Figure 2 and Figure 3 As shown, the corner protector 2 includes a corner protector body 21, a rotating shaft 22 and a stopper 23. The rotating shaft 22 is inserted into the corner protector body 21. A torsion spring 24 is provided between the rotating shaft 22 and the corner protector body 21. When the corner protector 2 is installed on the box body 1, the corner protector body 21 is rotatably connected to a corner of the box body 1 through one end of the rotating shaft 22. The rotating shaft 22 is relatively fixed to the box body 1, and the stopper 23 is movably installed on the box body 1. Figure 4 and Figure 5 As shown, when the corner guard 2 is in the retracted state, that is, when it is not used to protect the corner of the box body 1, the torsion spring 24 is in an elastic deformation state, and the limiter 23 blocks the corner guard body 21, so that the corner guard body 21 cannot rotate; Figure 6 and Figure 7As shown, when the limiting member 23 is moved so as to be separated from the corner guard body 21, that is, after the limiting member 23 is released from blocking the corner guard body 21, the elastic force generated by the elastic deformation of the torsion spring 24 drives the corner guard body 21 to rotate and open relative to the rotating shaft 22 to protect the corner of the box body 1. During the period when the corner guard body 2 protects the corner of the box, even if the corner guard body 2 rotates due to an accidental collision, the rotation of the corner guard body 21 will cause the torsion spring 24 to produce elastic deformation, and the elastic force of the torsion spring 24 can drive the corner guard body 21 to rotate and return to protect the corner of the box body 1, thereby effectively solving the problem that the corner guard 2 is easily dropped due to an accidental collision during use and loses its original protective function, so that the corner guard 2 effectively guarantees its protective function.

[0028] In this embodiment, if Figure 3 As shown, the limit member 23 includes an unlocking handle 231 and an unlocking rod 232. The unlocking handle 231 serves as an unlocking operation end, and the end of the unlocking rod 232 away from the unlocking handle 231 is used to block the corner guard body 21. When the unlocking handle 231 is pulled, the unlocking rod 232 is driven to move away from the corner guard body 21 to release the blocking limit on the corner guard body 21. In this embodiment, an unlocking spring 233 is sleeved on the unlocking rod 232. When the unlocking handle 231 drives the unlocking rod 232 to move away from the corner guard body 21, the unlocking spring 233 produces elastic deformation. When the pulling force applied to the unlocking handle 231 is removed, the elastic force generated by the elastic deformation of the unlocking spring 233 can drive the unlocking rod 232 to move and reset. That is to say, in the process of the corner guard body 21 protecting the corner of the box body 1, the corner guard body 21 cannot be rotated to the retracted state due to accidental collision. That is to say, it can effectively ensure that the corner guard body 21 can be rotated and reset to the open state after an accidental collision to protect the corner of the box body 1. Even if the unlocking handle 231 is accidentally touched and the unlocking rod 232 is moved, the unlocking rod 232 can also be automatically reset after the accidental collision is gone. In this embodiment, the end of the unlocking rod 232 close to the unlocking handle 231 is plugged with the unlocking handle 231. Specifically, the end of the unlocking rod 232 close to the unlocking handle 231 is provided with an insert block 2321, and the end of the unlocking handle 231 close to the unlocking rod 232 is provided with a socket that matches the insert block 2321. In this embodiment, the end of the unlocking rod 232 away from the unlocking handle 231 is provided with a limit head 2322, which is used to prevent the unlocking rod 232 from being separated from the box body 1.

[0029] In this embodiment, if Figure 3As shown, the rotating shaft 22 is threadedly connected with the corner protector body 21. Specifically, the rotating shaft 22 is provided with an external thread, and the corner protector body 21 is provided with an internal thread that matches the external thread on the rotating shaft 22. The rotating shaft 22 and the box body 1 are relatively fixed together. When the corner protector body 21 rotates relative to the box body 1, the rotating shaft 22 does not rotate, and the corner protector body 21 rotates and moves relative to the rotating shaft 22. Figure 5 and Figure 7 As shown, the function of the above threaded connection is that when the corner protector body 21 is in the retracted state, the corner protector body 21 will not protrude relative to the box body 1. At the same time, when the corner protector body 21 is in the open state, it can protect the corner of the box body 1, that is, the amount of movement of the corner protector body 21 relative to the rotating shaft 22 is greater than or equal to the wall thickness of the corner protector body 21 at the position corresponding to the box body 1. In this embodiment, the corner protector 2 also includes a limit pin 25. When the corner protector 2 is installed on the box body 1, the limit pin 25 is penetrated in the box body 1 and one end is used to limit the rotating shaft 22 to prevent the rotating shaft 22 from rotating relative to the box body 1. An auxiliary groove 221 is provided at one end of the rotating shaft 22 away from the box body 1. The auxiliary groove 221 can be a straight groove or a cross groove. The rotating shaft 22 is driven to rotate through the auxiliary groove 221 to realize the threaded connection between the rotating shaft 22 and the corner protector body 21. Therefore, a through mounting hole 211 is provided on the corner protector body 21 at a position corresponding to the installation of the rotating shaft 22, and the end of the rotating shaft 22 away from the box body 1 is located in the mounting hole 211. In this embodiment, the corner protector 2 further includes a pin 26, which is used to block the end of the mounting hole 211 on the corner protector body 21 away from the box body 1.

[0030] The above specific embodiments are merely explanations of the present invention, and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the above embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
