As used in the description of the embodiments of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms of "a", "an" and "the" are intended to include plural forms.

[0036] As shown in the accompanying drawings, a specific embodiment of the present invention is a high-resolution OLED display transfer rack, comprising an upper cover 1 and a plurality of rack units;

[0037] The placement rack unit includes a rack body 4, a trigger assembly, and two sets of display screen fixing assemblies, wherein the display screen fixing assemblies are used to fix multiple OLED display screens 8;

[0038] A plurality of the rack units are stacked and buckled together, and when the rack units on the upper layer are stacked and buckled on the rack units on the lower layer, the trigger component drives the display screen fixing component on the rack units on the lower layer to fix the OLED display screen 8;

[0039] The upper cover 1 covers the uppermost shelf unit and drives the display screen fixing assembly on the uppermost shelf unit to fix the OLED display screen 8 .

[0040] In the above scheme, by stacking together the placement rack units that can fix multiple OLED display screens, the space utilization rate can be improved. At the same time, when the upper placement rack units are stacked and snapped onto the lower placement rack units, the trigger component drives the display screen fixing component on the lower placement rack units to fix the OLED display screen. After the upper placement rack units are removed, the fixation of the OLED display screen by the display screen fixing component on the lower placement rack units can be cancelled, making it easy to fix and remove the OLED display screen.

[0041] Among them, the display screen fixing assembly includes a movable rod 14, a spring 17, a limit plate 16, a limit ring 15, a plurality of fixed cavities 9 and a plurality of clamping mechanisms. The frame body 4 is provided with movable holes 24 that cooperate with the movable rod 14. The fixed cavities 9 are arranged in two rows on the frame body 4. The fixed cavities 9 are connected with the movable holes 24 through the L-shaped hole 12. The clamping mechanism is movably installed in the L-shaped hole 12. One end of several of the clamping mechanisms is connected to the movable rod 14, and the other end extends into the fixed cavity 9 to fix the OLED display screen 8. The limit ring 15 is fixedly arranged at one end of the movable rod 14, and the limit plate 16 is installed on the frame body 4. The spring 17 is sleeved on the movable rod 14, and one end of the spring 17 abuts against the limit ring 15, and the other end abuts against the limit plate 16.

[0042] In this embodiment, further, the clamping mechanism includes an L-shaped rod 13 and a clamping plate 6, one end of the L-shaped rod 13 is connected to the movable rod 14, and the clamping plate 6 is connected to the other end of the L-shaped rod 13 and is located in the fixed cavity 9. Furthermore, in order to improve the buffering effect of the clamping mechanism, a soft pad 1 is provided on the end surface of the clamping plate 6 in contact with the OLED display screen 8, wherein the soft pad 1 can also be replaced by a buffer airbag with greater deformation, and a soft pad 2 7 is provided on the end surface of the fixed cavity 9 in contact with the OLED display screen 8.

[0043] The trigger assembly includes two trigger plates 2 and a trigger block 10. The trigger plate 2 is fixedly mounted at the lower part of the frame 4. The upper end of the frame 4 is provided with a matching hole 11 that matches the trigger plate 2. The matching hole 11 is connected to the movable hole 24. The trigger block 10 is installed in the matching hole 11 and connected to one end of the movable rod 14. After the trigger plate 2 enters the matching hole 11, it squeezes the trigger block 10 to drive the movable rod 14 to move and then drives the clamping mechanism to fix the OLED display screen 8. Specifically, the cross section of the trigger block 10 is a right-angled trapezoid, the surface of the trigger plate 2 in contact with the trigger block 10 is a curved surface 22, and the surface of the trigger block 10 in contact with the trigger plate 2 is an inclined surface 23.

[0044] In this embodiment, a slot 21 is provided on the end surface of the trigger plate 2 close to the trigger block 10 , and one end of the trigger block 10 close to the slot 21 can be engaged with the slot 21 .

[0045] It should be noted that, in order to enable the upper and lower placement rack units to be separated smoothly, a release assembly is also provided on the rack body 4, and the release assembly includes a push rod 18 and two L-shaped rods 20. The rack body 4 is provided with an active cavity 19 that cooperates with the push rod 18 and an active cavity 2 that cooperates with the L-shaped rod 20. The active cavity 19 is connected to the active hole 24 through the active cavity 2. The two L-shaped rods 20 are respectively provided at both ends of the push rod 18, and one end of the L-shaped rod 20 away from the push rod 18 is connected to the active rod 14. Specifically, when the two placement rack units are to be separated, the push rod is first pushed inward, and the push rod drives the trigger block to move to the right, and the trigger block is disengaged from the card slot on the trigger plate, and the two placement rack units can be separated.

[0046] In the above scheme, after the OLED display screen is placed in the fixed cavity on the frame, another frame is stacked on the frame, and the trigger plate squeezes the trigger block to move to the right under the action of external force, thereby driving multiple clamping mechanisms on the movable rod to fix the OLED display screen. At the same time, the elastic force provided by the spring can drive the movable rod to firmly clamp the trigger block into the card slot of the trigger plate. When the upper placement rack unit is removed, the movable rod drives the clamping mechanism to move to the left under the action of the spring to cancel the fixation of the OLED display screen. The scheme of the present invention can fix and take out the OLED display screen conveniently.

[0047] Specifically, the trigger plate 2 is disposed on the lower end surface of the upper cover 1, and the upper cover is covered on the uppermost frame. The trigger plate on the upper cover cooperates with the trigger block on the uppermost frame to drive the clamping mechanism to lock the OLED display screen. It should be noted that the upper cover is also provided with a release component with the same structure as that on the frame, so it will not be described in detail.

[0048] Among them, in order to improve the stability of the connection between the upper and lower frames, a limiting groove 5 is set on the upper end surface of the frame 4, and a clamping plate 3 cooperating with the limiting groove 5 is set on the lower end surface of the frame 4. The clamping plate on the upper frame cooperates with the limiting groove on the lower frame, so that the connection between the upper frame and the lower frame is more stable.

[0049] The above description is only for the best embodiment of the present invention, but it should not be understood as limiting the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the scope of protection of the independent claims of the present invention are within the scope of protection of the present invention.
