At present, a display screen used outdoors generally adopts a door opening and front maintenance mode on a maintenance structure, and has the problems of complex door opening structure, reserved door opening space, limited display screen installation, high front maintenance structure cost and the like.

In view of this, maintenance disassembly and assembly structures can be provided in the embodiments of the present disclosure, and problems in the related art are solved by a structure of laterally sliding in and out of a display screen body.

As shown in fig. 1, a schematic structural diagram of a display screen with an application maintenance disassembly structure in an embodiment of the present disclosure is shown.

The display 1 in fig. 1 is an assembled structure, and the display 1 includes a housing 10 and a mounting area is formed in the housing 10 for disposing display related components. Illustratively, the screen 10 is illustrated as a square frame structure. The front surface of the display screen 1 may be provided with a light-transmitting panel 11, such as glass.

As shown in fig. 1, the maintenance dismounting structure includes a mounting opening 12 and an incoming line cover 13. The mounting opening 12 is provided on a side surface of the screen case 10, and communicates with the mounting area into the screen case 10. The wire inlet cover 13 can be inserted and removed from the mounting opening 12 to enter and exit the mounting area. The incoming line cover 13 is loaded with a display control circuit board 131. For example, the display control circuit board 131 may draw out various electrical wires for connection to other circuit components (e.g., a light emitting unit of LED material, etc.), such as the illustrated control wire 1311 and ground wire 1312.

In order to make the wire inlet cover 13 have a certain limiting function when being detached from the mounting port 12, so as to prevent the wire inlet cover 13 from being directly separated from the mounting port 12 under the unexpected movement, a limiting structure can be designed between the wire inlet cover 13 and the mounting port 12.

In the example of fig. 1, the incoming wire cover 13 is rotatably provided with a stopper 132. The stopper 132 is rotatable in a first lateral direction and is limited in rotation in an opposite second lateral direction. The second side direction corresponds to the insertion direction of the incoming line cover 13 relative to the mounting opening 12. Illustratively, the upper end of the limiting member 132 is connected to the wire feeding cover 13 through a rotation shaft 133 so as to be rotatable about the rotation shaft 133. In fig. 1, the right direction is the first side direction, and the left direction is the second side direction. In the illustrated example, a stop 134 may be provided on the path of the left rotation of the stop 132 to limit its rotation in the second lateral direction. The stop 134 may be exemplified by a post, support post, or other type of object.

The rotatable outer end of the stopper 132 extends beyond one side edge of the mounting port 12, which is illustrated as the lower edge of the mounting port 12. In the process of inserting the wire inlet cover 13 into the mounting port 12, the outer end of the limiting member 132 is blocked by the outer surface of the flange (denoted by a) outside the edge to rotate in the direction away from the mounting port 12, that is, to the right, until the limiting member 132 rotates along with the wire inlet cover 13 entering the mounting port 12 and returns to the inner surface of the flange corresponding to the position. In order to enable the limiting member 132 to smoothly enter the mounting opening 12, an outer edge of the outer end of the limiting member 132 in the second lateral direction is an inclined plane, so as to smoothly guide the limiting member 132 into the mounting opening 12 when contacting with the lower edge of the mounting opening 12.

It will be appreciated that when the incoming lid 13 is moved to the left out of the mounting opening 12, the stop 132 is restricted from rotating to the left to abut against the inner surface of the flange, so that the incoming lid 13 will not be moved out of the way directly in an unintended situation, but the incoming lid 13 will be lifted up by the user or the stop 132 will be rotated in advance so that the stop 132 will not be stopped by the flange, thereby being removed from the mounting opening 12.

For example, in order to achieve a sealing contact between the mounting opening 12 and the wire inlet cover 13, a sealing ring 14 may be provided around the periphery of the mounting opening 12. When the wire inlet cover 13 is positioned deep into the mounting port 12, the sealing ring 14 is pressed between the periphery of the mounting port 12 and the wire inlet cover 13.

As shown in fig. 2, the display screen 1 is shown in a state that the wire-feeding cover 13 is completely inserted into the mounting opening.

It can be seen that the display control circuit board 131 on the incoming line cover 13 is maintained in a manner of plugging and unplugging the incoming line cover on the side surface, so that the problems in the related art can be effectively solved, the structure is simple, the operation and maintenance are convenient, the occupied operation space is small, and the installation of the display screen 1 is not limited (the maintenance and disassembly structure does not relate to the front surface and the back surface of the display screen 1).

Referring to fig. 3, a partially disassembled structure of the display screen 1 according to the embodiment of the disclosure is shown. The maintenance and disassembly structure may further include a guide assembly 15 fixedly provided on the screen housing 10, and extending from the mounting opening 12 in a direction away from the mounting opening 12. The guide assembly 15 forms a guide area that slidably engages the incoming line cover 13. In the example of fig. 3, the lower frame member 104 in the screen case 10 of the frame structure is removed, and the display panel 16 and the light-transmitting panel 11 are partially scribed down the screen case 10, thereby exposing the guide assembly 15. Illustratively, the guide assembly 15 may include a pair of guide rails 152. The incoming lid is inserted from the mounting port 12 into, i.e., slidably engaged with, the pair of rails 152 (e.g., engaged within grooves of the rails 152, or engaged with the rails 152, etc.), thereby limiting the guide area in which the incoming lid can slide on the guide assembly 15.

As shown in connection with fig. 3 to 6. Fig. 4 shows a schematic structural view of a frame structure in which the guide assembly 15 is mounted to the screen case 10 in the embodiment of the present disclosure. Fig. 5 shows a schematic view of the remaining structure of the screen case 10 with the lower frame member 104 removed. Fig. 6 shows an exploded structure diagram of the remaining portion of the screen case 10 in fig. 5.

In fig. 3, the frame structure of the screen case 10 includes an upper frame member 101, a pair of side frame members (a left frame member 102 and a right frame member 103) connecting both ends of the upper frame member 101, and a lower frame member 104 connecting a pair of side frame members facing away from both ends of the upper frame, and fig. 4 to 6 show the upper frame member 101, the left frame member 102 and the right frame member 103. The mounting opening 12 is formed in one of the side frame members, in the example shown as the right frame member 103. Each frame member may be a hollow profile extending in a straight line. Of course, in other embodiments, if the shape of the display screen 1 is to be changed, the shape of the frame member is also changed correspondingly, and is not limited to a straight line.

In fig. 3, the two ends of the guide assembly 15 are respectively fixed to the opposite wall surfaces of the pair of side frame members. The fixing mode can be screw lock fixing. Referring to fig. 4, the guide assembly 15 has fixing pieces 151 connecting two ends of the pair of guide rails 152 facing away from the mounting opening 12, the fixing pieces 151 are fixed to opposite wall surfaces of the corresponding side frame member (the left frame member 102 in the drawing) by screwing, the pair of guide rails 152 are formed with screw holes toward the other end of the mounting opening 12, and screws are directly combined to fix to the side frame member (the right frame member 103 in the drawing) provided with the mounting opening 12.

Illustratively, the upper frame member 101 is fixed at a predetermined angle, such as 90 ° from vertical as shown in the figures, to the left and right frame members 102 and 103. The splicing surfaces of the upper frame member 101 and the side frame members 102 and 103 are mutually parallel inclined surfaces, and in the same way, the contact surfaces of the lower frame member 104 and the side frame members 102 and 103 are mutually parallel inclined surfaces, and part of space is reserved by the inclined surfaces, so that the frame members can be spliced into a required included angle. For example, the inclination angle of the inclined plane of the two frame members spliced together is 45 °, and then the included angle of the two frame members spliced together is 90 °.

In fig. 5, the remaining frame body of the screen case 10 after the lower frame member 104 is detached is shown, including the upper frame member 101, the left frame member 102, and the right frame member 103.

Taking fig. 6 as an example, the upper frame member 101 is fixedly connected to the left frame member 102 and the right frame member 103 of the same pair through a corner connecting member 16. The corner connector 16 includes a first portion and a second portion that are connected at a predetermined angle to each other, such as 90 ° from each other as illustrated in the figures. The first and second portions are for being fixed to objects to be connected, such as the upper frame member 101 and the left frame member 102, the upper frame member 101 and the right frame member 103, respectively. And determining the included angle between the objects to be connected by the preset angle. By way of example, the angle between the first and second portions of the corner connector 16 is 90 ° such that the angle between the upper frame member 101 and the left and right frame members 102, 103 is 90 °.

Referring back to fig. 3, the inner wall of the frame structure is provided with a groove structure for engaging the transparent panel 11 and the display panel 16. Specifically, at least two groove portions that are mutually communicated are respectively disposed in the upper frame member 101, the left frame member 102, the right frame member 103, and the lower frame member 104 to form at least two annular grooves for respectively clamping the light-transmitting panel 11 and the display panel 16. When the lower frame member 104 is removed, the lower ends of the grooves in the left and right frame members 102 and 103 are opened to accommodate the light-transmitting panel 11 and the display panel 16, slide upward to the top frame member 101, and then the lower frame member 104 is mounted to complete the mounting of the light-transmitting panel 11 and the display panel 16.

As further shown in fig. 7, a schematic exploded view of the upper frame member 101 in the embodiment of the disclosure is shown. Fig. 8 shows a schematic diagram of the combined structure of the upper frame member 101 in the embodiment of the disclosure.

As shown in fig. 7, the upper frame 101 is further fixed with a reinforcing plate 111 on the frame body to strengthen the strength. The two ends of the upper frame member 101 are respectively screwed and fixed with the horizontal sections of the external corner members 112, and the two vertical extending sections of the external corner members 112 can be respectively screwed and fixed with the two side frame members 102 and 103. Fig. 8 shows the state in which the outer corner pieces 112 and the reinforcing plates (hidden) at the same ends of the upper frame member 101 are screw-locked. Similarly, the lower frame member 104 may be of similar construction, for example.

According to fig. 1 to 8, an assembly procedure of the display screen 1 can also be given.

Starting with fig. 7, the upper frame 101 is assembled until the upper frame 101 of fig. 8 is assembled.

Then, as shown in fig. 6, the upper frame 101 is fixedly connected to the left frame 102 and the right frame 103 by a pair of fixing connectors, respectively, until the upper frame 101 is assembled to the left frame 102 and the right frame 103 as shown in fig. 5.
