Referring to
In this embodiment, the support 10 includes at least one mounting portion 11 and at least one fixing portion 12 connected to the mounting portion 11. The stop block 100 is stably mounted by connecting the mounting portion 11 of the support 10 with the display panel packaging structure 600. The fixing portion 12 of the support 10 is configured to mount the buffer 20, i.e., the buffer 20 is attached to the fixing portion 12, and covers a surface of the fixing portion 12 adjacent to the mounting portion 11 and two lateral sides connecting the surface and facing to each other.
Optionally, the support 10 includes one or more mounting portions 11, and one or more fixing portions 12 connected to the mounting portions 11. As shown in
Of course, in this embodiment, the mounting portion 11 and the fixing portion 12 of the support 10 may be defined in the same plane or defined with an included angle, and the specific structure is determined according to the structure installed in the box body, which is not limited here.
As shown in
Specifically, the support 10 has a cross-shaped structure, two mounting portions 11 are defined adjacent to each other and with a right angle between them, and two fixing portions 12 are defined adjacent to each other and with a right angle between them. When the stop block 100 is installed in the box body of the display panel packaging structure 600, the two mounting portions 11 are connected and fixed to the box body, and the two fixing portions 12 are attached to the lateral side of the box body. It may be understood that each fixing portion 12 is defined with a buffer 20, and optionally, the buffer 20 covers the surface and lateral sides of the fixing portion 12 that are not in contact with the box body, so that the buffer effect on the display panel may be achieved while saving materials.
It may be appreciated that by covering the buffer 20 on one surface of the fixing portion 12 adjacent to the mounting portion 11, and the two lateral sides connecting the surface and facing to each other, direct contact between the four corners of the display panel and the support 10 in packaging and transportation of the display panel is avoided, and the display panel is protected from being damaged by colliding with the support 10. Further, the buffer 20 is simultaneously covered on two lateral sides of the fixing portion 12 facing to each other 12, so that the stop block 100 may protect the display panel from being damaged by colliding with the support 10 regardless of whether the stop block 100 is installed in the box body of the display panel packaging structure 600 in the forward direction or in the box body of the display panel packaging structure 600 in the reverse direction. The stop block 100 provided by the present disclosure may not only has good buffer performance, but also has a simple structure and may be conveniently installed in the box body.
In some embodiments, as shown in
Specifically, the fixing portion 12 of the support 10 is a plate-like structure. In order to make the buffer 20 cover a surface of the fixing portion 12 adjacent to the mounting portion 11 and two lateral sides connecting the surface and facing to each other, the first buffer part 21, the second buffer part 22 and the third buffer part 23 of the buffer 20 cooperatively form a receiving cavity 24 of a U-shaped structure. The plate-like fixing portion 12 is inserted into the receiving cavity 24, making the first buffer part 21 of the buffer 20 abut against the surface of the fixing portion 12, and the second buffer part 22 and the third buffer part 23 respectively abut against two sides of the fixing portion 12 facing to each other.
It may be understood that the lateral sides of the fixing portion 12 and the surfaces connecting the lateral sides may be defined perpendicular to each other, but may also be defined with an included angle, which is not limited here. In order that the buffer member 20 may be securely sleeved on the fixing portion 12, the receiving cavity 24 of U-shaped structure formed cooperatively by the first buffer part 21, the second buffer part 22 and the third buffer part 23 of the buffer 20 is matched with the structure of the fixing portion 12.
In this embodiment, the stop block 100 may prevent the display panel from being damaged by collision regardless of its installation in the box body of the display panel packaging structure 600 in the forward direction or its installation in the box body of the display panel packaging structure 600 in the reverse direction. The second buffer part 22 and the third buffer part 23 of the buffer 20 are defined facing to each other at both ends of the first buffer part 21, that is, when the buffer 20 is connected to the fixed portion 12, the second buffer part 22 and the third buffer part 23 respectively abut against the two lateral sides of the fixed portion 12 facing to each other.
Thus, when the stop block 100 is installed in the box body of the display panel packaging structure 600 in the forward direction, the second buffer part 22 is flush with the top of the side wall of the box body, and the first buffer part 21 and the second buffer part 22 play a role in buffering and protecting the display panel when the display panel packaging is placed in the display panel packaging structure 600. When the stop block 100 is reversely installed in the box body of the display panel packaging structure 600, the third buffer part 23 is flush with the top of the side wall of the box body, and the first buffer part 21 and the third buffer part 23 play a role in buffering and protecting the display panel in the process of putting the display panel packaging into the display panel packaging structure 600.
In some embodiments, as shown in
In some embodiments, as shown in
It may be understood that the step surface 13 is configured not only to limit the second buffer 22 or the third buffer 23, but also to prevent the second buffer 22 or the third buffer 23 from sliding when mounted on the fixed part 12. At the same time, it is also advantageous to realize that the lateral side of the mounting portion 11 is flush with the lateral side where the buffer 20 is fixed to the fixing portion 12. Optionally, the two lateral sides of the fixing portion 12 facing to each other and the two lateral sides of the mounting portion facing to each other cooperatively form step surfaces 13. Thereby, the second buffer part 22 and the third buffer part 23 are limited by the step surfaces 13 on the two sides of the fixing portion 12 facing to each other, respectively. Thereby, the vertical distance between the outer side wall of the second buffer part 22 of the buffer 20 and the outer side wall of the third buffer part 23 equals the height of the mounting portion 11 of the support 10, that is, the thicknesses of the second buffer part 22 and the third buffer part 23 equal the height of the step surface 13.
As shown in
In some embodiments, as shown in
The definition of the extension 25 facilitates the firm connection of the buffer 20 with the fixing portion 12. Furthermore, a limiting member 26 is protruded from the extension part 25, the fixing portion 12 defines a limiting hole 14 adjacent to the step surface 13. By the cooperation of the limiting member 26 and the limiting hole 14, the buffering member 20 is further firmly connected with the fixing portion 12 to prevent the buffering member 20 from falling off from the fixing portion 12. It may be understood that the limiting member 26 and the limiting hole 14 may be a convex and concave fit structure, or a snap fit structure, although other structures capable of firmly connecting the buffering member 20 with the fixing portion 12, such as screw and screw fit, which are not limited here.
In an embodiment, as shown in
Referring to
The box 400 defines a receiving cavity 410 which is configured to accommodate a display panel, the inner side wall of the accommodation cavity 410 is defined with a mounting groove 420, the mounting portion 11 of the support 10 is accommodated in the mounting groove 420, the fixing portion 12 of the support 10 is attached to the inner side wall of the receiving cavity 410, and the buffer 20 is defined on the side of the fixing portion 12 facing away from the inner side wall of the receiving cavity 410.
It may be appreciated that the mounting and fixing of the stop block 100 is realized through the cooperation of the mounting portion 11 of the support 10 and the mounting groove 420. The fixing portion 12 is attached to the inner side wall of the receiving cavity 410, which is beneficial to increasing the mounting stability of the stop block 100. The buffer 20 is defined on the side of the fixing portion 12 facing away from the inner side wall of the receiving cavity 410, so that the buffer 20 may buffer the display panel mounted or placed in the receiving cavity 410 of the box 400 and prevent the display panel from being damaged.
In some embodiments, as shown in
As may be appreciated, the definition of the limiting groove 430 is advantageous to further realize the stable installation of the stop block 100. When the stop block 100 is installed in the receiving cavity 410 of the box 400, the first buffer part 21 of the buffer 20 is parallel to the inner side wall of the cavity 410, and one of the second buffer part 22 and the third buffer part 23 is located in the limiting groove 430 and abuts against the bottom wall of the limiting groove 430, with the other one being flush with the side wall of the box 410. Thus, when the stop block 100 is installed in the cavity 410 of the box 400, one of the second buffer part 22 and the third buffer part 23 together with the first buffer part 21 plays a buffering role on the display panel to avoid the damage of the display panel. And, such definition is not only beneficial to improving the buffering function of the stop block 100, but also beneficial to improving the installation convenience of the stop block 100.
The display panel packaging structure 600 provided by the present disclosure not only has a simple structure, but also has good buffering performance.
