[0034] Reference below Figures 1 to 5 The back frame and the display screen according to the embodiments of the utility model are described.

[0035] According to the back frame of the first embodiment of the utility model, Figures 1 to 5 As shown, it includes a back frame body 100 and an access panel 200 .

[0036] The rear side of the back frame body 100 is provided with an inspection port 101 , and the back frame body 100 is provided with a first connection structure 102 and a limiting portion 103 .

[0037] One side of the inspection plate 200 is rotatably connected to the back frame body 100, and the inspection plate 200 is provided with a second connection structure 201, wherein the inspection plate 200 can be rotated to a first state of closing the inspection opening 101 and a second state of opening the inspection opening 101, when the inspection plate 200 is in the first state, the first connection structure 102 can be detachably connected to the second connection structure 201, and when the inspection plate 200 is in the second state, the limit portion 103 limits the rotation of the inspection plate 200.

[0038] In the utility model, when it is necessary to inspect and repair the circuit board or the control module, the first connecting structure 102 is separated from the second connecting structure 201, and then the inspection plate 200 is rotated so that the inspection plate 200 is located in the second state of the open inspection port 101. The limit portion 103 limits the rotation of the inspection plate 200, so that the inspection plate 200 can be kept in the second state of the open inspection port 101. Thereafter, the circuit board or the control module can be inspected and repaired. After the inspection is completed, the inspection plate 200 is rotated so that the inspection plate 200 is located in the first state of the closed inspection port 101, and finally the first connecting structure 102 and the second connecting structure 201 are connected to each other.

[0039] According to the back frame of the first embodiment of the utility model, when it is necessary to inspect and repair the circuit board or the control module in the back frame body 100, the operation is more convenient and more time-saving and labor-saving.

[0040] It should be noted that the first connection structure 102 and the second connection structure 201 can be connected by snapping or by fasteners. When the access panel 200 is in the first state, the access panel 200 is parallel or substantially parallel to the rear side of the back frame body 100. When the access panel 200 is in the second state, the access panel 200 is perpendicular or substantially perpendicular to the rear side of the back frame body 100.

[0041] In some embodiments of the present invention, Figure 1 , Figure 3 and Figure 5 As shown, the inspection plate 200 has a first side 202, which is provided with a rotating shaft 203 and is rotatably mounted on the back frame body 100 via the rotating shaft 203. When the inspection plate 200 is in the second state, the first side 202 abuts against the rear side of the limiting portion 103 to limit the rotation of the inspection plate 200.

[0042] The access plate 200 is rotatably mounted on the back frame body 100 via the rotating shaft 203. When the access plate 200 is in the second state, the access plate 200 is perpendicular or substantially perpendicular to the rear side of the back frame body 100, and the access plate 200 is located behind the limiting portion 103. The first side 202 of the access plate 200 abuts against the rear side of the limiting portion 103. The interaction between the first side 202 of the access plate 200 and the rear side of the limiting portion 103 can limit the access plate 200 from rotating freely. In this embodiment, the access plate 200 can be limited from rotating freely by abutting against the limiting portion 103, which has a simple structure and is easy to operate.

[0043] It should be noted that the limiting portion 103 may also be other limiting methods. For example, the limiting portion 103 may be a limiting bolt. When the inspection plate 200 is in the second state, the limiting portion 103 connects the inspection plate 200 and the back frame body 100, and can also limit the rotation of the inspection plate 200.

[0044] In some embodiments of the present invention, Figure 3 As shown, the first side 202 is provided with a connection portion 204, the rotating shaft 203 is connected to the connection portion 204, the side of the inspection port 101 close to the rotating shaft 203 is provided with a mounting groove 104, the rear side of the mounting groove 104 is open, the mounting groove 104 is provided with a mounting hole 105 on at least one side in the length direction of the first side 202, the connection portion 204 is located in the mounting groove 104, and the rotating shaft 203 is rotatably installed in the mounting hole 105. For example, the mounting groove 104 may be provided with a mounting hole 105 on one side in the length direction of the first side 202, the side of the connection portion 204 close to the mounting hole 105 is provided with a rotating shaft 203, and the rotating shaft 203 is rotatably installed in the mounting hole 105. In this embodiment, the connection portion 204 and the mounting groove 104 with the rear side opening are provided, which makes it easier for the inspection panel 200 to switch between the first state and the second state, and avoids the inspection panel 200 from getting stuck during the rotation process.

[0045] In some embodiments of the present invention, Figure 3As shown, a circular chamfer 106 is provided between the rear side of the back frame body 100 where the mounting hole 105 is provided and the side near the inspection port 101. This arrangement makes it easier for the inspection panel 200 to switch between the first state and the second state, and avoids the inspection panel 200 from getting stuck during rotation.

[0046] In some embodiments of the present invention, the rotating shaft 203 is made of elastic material. For example, the rotating shaft 203 can be made of elastic plastic or elastic rubber, so that when the access panel 200 rotates from the first state to the second state, the rotating shaft 203 can produce elastic deformation, and then when the access panel 200 rotates to a position close to the second state, the distance between the first side 202 of the access panel 200 and the rear side of the back frame body 100 can be finely adjusted, so that the distance between the first side 202 of the access panel 200 and the rear side of the back frame body 100 is slightly expanded, so that the first side 202 of the access panel 200 can slide smoothly to the rear side of the abutment limit portion 103, thereby avoiding the access panel 200 from getting stuck during rotation, and reducing the damage to the access panel 200. Since the rotating shaft 203 is an elastic structure, when the inspection plate 200 rotates to the second state, the first side 202 of the inspection plate 200 can also elastically abut the rear side of the limiting portion 103, so that the inspection plate 200 and the limiting portion 103 interact with each other to better prevent the inspection plate 200 from rotating.

[0047] It should be noted that the connecting portion 204 may be made of an elastic material, or both the rotating shaft 203 and the connecting portion 204 may be made of an elastic material.

[0048] In some embodiments of the present invention, Figure 5 As shown, the rear side portion of the back frame body 100 protrudes backward to form a limiting portion 103. The limiting portion 103 is integrally formed with the back frame body 100, which has higher structural strength and is more convenient to process. Of course, in some other embodiments of the utility model, the limiting portion 103 can also be welded, bonded or installed on the back frame body 100 by fasteners.

[0049] In some embodiments of the present invention, Figure 1 As shown, at least two limiting portions 103 are provided and arranged along the length direction of the first side 202. For example, two limiting portions 103 may be provided and arranged along the length direction of the first side 202, so that the abutment effect between the limiting portion 103 and the first side 202 of the access plate 200 is better, thereby better limiting the rotation effect of the access plate 200.

[0050] In some embodiments of the present invention, Figure 4As shown, the access panel 200 has a second side 205 opposite to the first side 202, and the second connecting structure 201 is arranged on the second side 205. When the access panel 200 is in the first state, the first connecting structure 102 can be mutually engaged with the second connecting structure 201. For example, one of the first engaging structure and the second engaging structure can be provided with a slot, and the other can be provided with a engaging portion. When the access panel 200 is in the first state, the engaging portion is engaged in the slot. In this embodiment, when the access panel 200 is in the first state, the access panel 200 is locked by the mutual engagement of the first connecting structure 102 and the second connecting structure 201, so as to prevent the access panel 200 from rotating at will, so that the access panel 200 can be kept in the state of closing the access opening 101, and the structure is simple and the operation is convenient. Moreover, the second connecting structure 201 is arranged on the second side 205 opposite to the first side 202, so that the locking effect is better.

[0051] In some embodiments of the present invention, Figure 4 As shown, the access panel 200 has a second side 205 opposite to the first side 202, and a side wall 107 is provided on the side of the access opening 101 close to the second side 205, and a through operation opening 108 is provided on the side wall 107, and the rear side opening of the operation opening 108 is provided. With such a configuration, when the first clamping structure and the second clamping structure need to be separated from each other, the staff can insert their fingers into the operation opening 108 and locate them on the inner side of the access panel 200, and then push the access panel 200 outward to separate the first clamping structure and the second clamping structure, which is more convenient to operate and saves time and effort.

[0052] According to the display screen of the second embodiment of the utility model, Figure 1 and Figure 2 As shown, it includes the back frame of the first embodiment. The display screen may also be provided with a display module, and the display module may be provided on the front side of the back frame body 100 of the back frame.

[0053] According to the display screen of the embodiment of the utility model, by adopting the back frame of the embodiment of the first aspect of the utility model, when it is necessary to inspect and repair the circuit board or the control module, the first connecting structure 102 is separated from the second connecting structure 201, and then the inspection plate 200 is rotated so that the inspection plate 200 is located in the second state of opening the inspection opening 101. The limiting part 103 limits the rotation of the inspection plate 200, so that the inspection plate 200 can be kept in the second state of opening the inspection opening 101, and then the circuit board or the control module can be inspected and repaired. After the inspection is completed, the inspection plate 200 is rotated so that the inspection plate 200 is located in the first state of closing the inspection opening 101, and finally the first connecting structure 102 and the second connecting structure 201 are connected to each other, which is more convenient to operate and saves time and effort.

[0054] It should be noted that, since the display screen can adopt all the technical solutions of the back frame of the first embodiment, it at least has all the beneficial effects brought by the technical solutions of the first embodiment. These additional beneficial effects will not be repeated here.

[0055] It is understandable that other structures and operations of the display screen according to the embodiment of the utility model are known to ordinary technicians in the field and will not be described in detail here.

[0056] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
