The adjustment pin 270 can move along the thickness direction of the frame 200 so that the locking protrusion 271 can approach and move away from the moving shell 330. When the locking protrusion 271 approaches the moving shell 330, the locking protrusion 271 can extend into and be limited in the first adjustment hole 263 and the second adjustment hole 264 to limit the adjustment pin 270 in the first adjustment hole 263 and the second adjustment hole 264. When the locking protrusion 271 moves away from the moving shell 330, the locking protrusion 271 can move out of the first adjustment hole 263 and the second adjustment hole 264, so that the adjustment pin 270 slides in the sliding channel 265 to drive the support assembly 300 to move up and down.

[0082] In some embodiments, the adjusting pin 270 is threadedly connected to the moving shell 330 to adjust the length of the adjusting pin 270 extending into the moving shell 330, so that the locking protrusion 271 can be moved into and out of the installation box 260. In other embodiments, the adjusting pin 270 penetrates into the moving shell 330 so that the adjusting pin 270 is engaged with the moving shell 330, so that the adjusting pin 270 can slide relative to the moving shell 330.

[0083] In some embodiments, the locking protrusion 271 is not provided on the adjustment pin 270. Two locking members (not shown in the figure) are provided on the installation box 260 relative to the first adjustment hole 263 and the second adjustment hole 264, and both locking members can pass through the adjustment pin 270 to limit the adjustment pin 270 in the first adjustment hole 263 or the second adjustment hole 264 respectively. In other embodiments, the locking member can be detachably provided on the installation box 260, and the two locking members can pass through the first adjustment hole 263 and the second adjustment hole 264 respectively.

[0084] In another embodiment of the mounting box 260 and the support assembly 300 of the utility model:

[0085] There is no need to set the movable shell 330. The upper end of the elastic member 310 is connected to the upper inner peripheral wall of the limiting channel 261, and the lower end of the elastic member 310 is connected to the abutting pin 320, so that the abutting pin 320 can move up and down in the limiting channel 261. The elastic member 310 can be elastically retracted so that the lower end of the abutting pin 320 can elastically extend out of the bottom of the installation box 260 or be accommodated in the installation box 260.

[0086] The adjusting pin 270 is connected to the abutting pin 320 to drive the abutting pin 320 to move up and down.

[0087] The installation box 260 may be provided with a stopper (not shown) relative to the abutting pin 320 , and the stopper may be detachably provided through the installation box 260 and extend into the limiting channel 261 . The stopper is located above the abutting pin 320 .

[0088] When the stopper extends into the limiting channel 261, the stopper can resist and stop the upward movement of the resisting pin 320, so that the end of the resisting pin 320 away from the center of the frame body 210 is located outside the bottom of the installation box 260, so that the resisting pin 320 can resist the ground, lift and protect the display screen 100.

[0089] When the abutment pin 320 needs to be retracted into the installation box 260, the staff can disassemble the abutment pin 320 so that the abutment pin 320 moves out of the limiting passage 261. Afterwards, the staff can move the abutment pin 320 upward and retract it into the installation box 260 by moving the adjustment pin 270 upward.

[0090] In some embodiments, the abutment pin 320 has a hole relative to the stopper so that the stopper can penetrate and limit the abutment pin 320. When the stopper moves out of the limiting passage 261, the staff moves the adjustment pin 270 upward to drive the abutment pin 320 to move upward. When the adjustment pin 270 moves to the second adjustment hole 264, the stopper limits the passage 261 and passes through the abutment pin 320 to limit the abutment pin 320 to the upper part of the limiting passage 261, and the adjustment pin 270 is limited in the second adjustment hole 264.

[0091] In other embodiments of the mounting box 260 and the support assembly 300 of the present invention:

[0092] There is no need to set the sliding channel 265. A handle (not shown in the figure) is provided on the cover plate 332, and the staff can pull the handle to drive the movable shell 330 to move up and down in the limiting channel 261. The adjusting pin 270 can be detachably connected to the movable shell 330. When the staff moves the movable shell 330 to the lower part of the limiting channel 261 by the handle, the adjusting pin 270 can extend into the first adjusting hole 263 and connect with the movable shell 330 to limit the support assembly 300 to the lower part of the limiting channel 261. When the staff moves the movable shell 330 to the upper part of the limiting channel 261 by the handle, the adjusting pin 270 can extend into the second adjusting hole 264 and connect with the movable shell 330 to limit the support assembly 300 to the upper part of the limiting channel 261.

[0093] See also Figure 2 , Figure 4 and Figure 7In this embodiment, a plurality of support components 300 are provided. The plurality of support components 300 are arranged at intervals at the bottom of the frame 200, so that the plurality of support components 300 cooperate with the support plate 230 to support the frame body 210, the display screen 100 and the electrical protection box 220. Moreover, under the action of the elastic member 310, the plurality of abutting pins 320 can abut against the uneven ground respectively, so that the display device can be stably supported on the uneven ground under the action of the plurality of support components 300 and the support plate 230.

[0094] In some embodiments, multiple groups of support components 300 are spaced apart along the length direction of the frame body 210. In other embodiments, the frame 200 includes multiple installation boxes 260, which are spaced apart and connected to the frame body 210 to accommodate multiple groups of support components 300 respectively.

[0095] See also Figure 2 , Figure 4 and Figure 7 In this embodiment, two installation boxes 260 are respectively arranged on both sides of the length direction of the frame body 210, and support components 300 are respectively arranged in the two installation boxes 260. The two support components 300 and the support plate 230 are distributed in a triangular shape to support the display screen 100, so that the center of gravity of the display device is located in the middle and rear of the display device, which can not only ensure the balance of the display device, but also make the display device fall backwards to protect the display screen 100 when it accidentally falls.

[0096] See also Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 In this embodiment, a locking box 280 is further provided at the top of the frame body 210 relative to the installation box 260. A locking hole 281 is provided on the upper surface of the locking box 280, and the locking hole 281 can accommodate and limit the abutting pin 320. When multiple display devices are connected in the up-down direction to assemble a display system, the adjustment pin 270 is located in the first adjustment hole 263, and the abutting pin 320 of the upper display device can extend into the locking hole 281 of the lower display device to lock the upper and lower display devices, thereby improving the connection strength of the display system.

[0097] When one of the display devices is damaged, the adjustment pin 270 is moved into the second adjustment hole 264, thereby driving the support assembly 300 to move upward in the limiting channel 261, and the lower end of the abutting pin 320 escapes from the locking hole 281 and moves into the installation box 260. Then the damaged display device is moved forward or backward to remove the damaged display device.

[0098] When a new display device is installed in the display system, the adjustment pin 270 is moved to the second adjustment hole 264, and the new display device is assembled into the display system. Finally, the adjustment pin 270 is moved into the first adjustment hole 263, and the abutting pin 320 is extended into the locking hole 281 to improve the connection strength of the display system.

[0099] See also Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 In this embodiment, the display device may further include an edge locking structure 400. The edge locking structure 400 may be disposed at the rear side of the frame body 210 and located on the peripheral side of the frame body 210. Any two adjacent display devices may be spliced ​​together through the edge locking structure 400.

[0100] In some embodiments, the side lock structure 400 can further include a male connection component 410 and a female connection component 420. A plurality of male connection components 410 can be disposed opposite to a plurality of female connection components 420 on opposite sides of the frame body 210 in the up-down direction or the left-right direction.

[0101] When multiple display devices are connected and combined, the male connection component 410 and the female connection component 420 on the opposite sides of the two display devices can be adapted to be engaged and connected, thereby achieving connection limit of the multiple display devices and ensuring the connection strength of the display system.

[0102] In some embodiments, the male connection component 410 is disposed on the left or right side of the frame body 210, and the male connection component 410 has a hook 411. The female connection component 420 is disposed on the right or left side of the frame body 210, and the female connection component 420 has a slot 421 capable of accommodating the hook 411. When multiple display devices are assembled, one display device is correspondingly inserted into the slot 421 of the female connection component 420 of another display device through the hook 411 of the male connection component 410, so as to perform left-right connection between the multiple display devices.

[0103] In other embodiments, the male connection component 410 and the female connection component 420 can also be located at the top and bottom of the frame body 210 to connect multiple display devices in the upper and lower directions.

[0104] See also Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 In this embodiment, the display device may further include a handle 510. The handle 510 may be disposed on the top of the frame body 210. The staff may lift and transport the display device through the handle 510.

[0105] In some embodiments, the handle 510 is rotatably connected to the frame body 210, and the rotation axis of the handle 510 extends in the left-right direction. When the user uses the handle 510, the handle 510 rotates to the upper side of the frame body 210. When the user does not use the handle 510, the handle 510 can be rotated to the rear side of the frame body 210. At this time, the handle 510 is located below the upper surface of the frame body 210, so that the handle 510 does not affect the assembly of multiple display devices.

[0106] See also Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 In this embodiment, the display device may further include a handle 520. The handle 520 may be disposed on the rear side wall of the frame body 210 to facilitate the staff to move the display device.

[0107] See also Figures 1 to 11 In this embodiment, when the staff transports the display device, the adjustment pin 270 is located in the first adjustment hole 263. The display device is lifted by the handle 510 and transported to the ground of the destination. After the display device is transported to the ground of the destination, the staff places the display device on the ground by the handle 510.

[0108] When the display device contacts the ground, the lower end of the abutting pin 320 contacts the ground first, and gradually presses the abutting pin 320 and the elastic member 310 under the gravity of the display device. The elastic member 310 elastically contracts to absorb the impact kinetic energy of the display device. Afterwards, the support plate 230 contacts the ground, so that the support plate 230 and the support assembly 300 jointly support the display screen 100.

[0109] When the display device is placed on the ground, at least part of the abutting pin 320 is located at the lower side of the frame 200, so that the abutting pin 320 can support the display screen 100 together with the support plate 230. The setting of the abutting pin 320 can make an angle between the bottom of the frame 200 and the ground, and the display screen 100 is far away from the ground, thereby effectively preventing the ground from hitting the display screen 100. In addition, when the display device may fall down under the external force, the elastic member 310 applies a backward elastic force to the frame 200 through the abutting pin 320, so that the display device falls backward, and the frame 200 hits the ground, so as to protect the display screen 100 and prevent the display screen 100 from being hit and damaged when the display device falls down.

[0110] When multiple display devices are moved to the destination and spliced ​​to form a display system, the support plate 230 of the upper display device abuts and connects to the carrier plate 240 of the lower display device, the installation box 260 of the upper display device abuts and connects to the locking box 280 of the lower display device, and the abutting pin 320 of the upper display device extends into the locking hole 281 at the lower side to ensure the connection strength of the multiple display devices in the vertical direction. Afterwards, the display devices on the left and right sides are connected through the side locking structure 400 to ensure the connection strength of the multiple display devices in the left and right directions.

[0111] When a display device inside the display system fails, the staff can rotate the adjustment pin 270 to move the locking protrusion 271 away from the moving shell 330, so that the locking protrusion 271 is out of the first adjustment hole 263. After that, the staff pushes the adjustment pin 270 upward, and the adjustment pin 270 drives the moving shell 330, the elastic member 310 and the abutting pin 320 to move upward. After the adjustment pin 270 slides into the second adjustment hole 264, the adjustment pin 270 is rotated to move the adjustment pin 270 toward the moving shell 330, so that the locking protrusion 271 is engaged in the second adjustment hole 264, and the moving shell 330, the elastic member 310 and the abutting pin 320 are limited to the upper part of the limiting channel 261, and the lower end of the abutting pin 320 is out of the locking box 280 and accommodated in the installation box 260. By unlocking the side lock structure 400, the staff can pull and disassemble the display device through the handle 520, so as to facilitate the replacement and installation of a new display device.
