Also, if a detailed description of known technology is unnecessary for the features of the present application shown, it is omitted. The embodiments described below by reference to the accompanying drawings are exemplary and are for the purpose of explaining the present application only, and cannot be interpreted as limiting the present application.

[0046] It is to be understood that the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise. It is further understood that the terms "comprise" and "comprising" and the like, when used in this specification, specify the presence of stated features, elements, components, and / or integers, but do not preclude the presence or addition of one or more other features, elements, components, integers, and / or groups thereof.

[0047] As shown in Figures 1-2 The display screen support provided by the embodiments of the present application mainly comprises a frame 1, a vertical beam 2, a plurality of horizontal beams 3 and a connecting member. The vertical beam 2 is arranged in the frame 1; the plurality of horizontal beams 3 are arranged in the frame 1 and connected perpendicularly to the vertical beam 2, and the connecting positions of the plurality of horizontal beams 3 and the frame 1 form a triangular reinforcing structure 4; the connecting member is fixedly connected with the reinforcing structure 4 and used for connecting the connecting member of another display screen support.

[0048] In the embodiments, the frame 1 is composed of four side beams, and the frame 1 is in a rectangular shape; alternatively, the frame 1 is in a square or rectangular shape. The vertical beam 2 and the horizontal beams 3 are connected with the frame 1, and the vertical beam 2 and the horizontal beams 3 are parallel to the corresponding side beams of the frame 1. The connecting member is used for connecting two adjacent display screen supports, and the connecting member can be classified into different types according to different functions, and the specific types will be described in detail later. A plurality of connecting members are arranged along the frame 1, and the reinforcing structure 4 must exist at the position where the connecting member exists.

[0049] The display screen support provided by the embodiments of the present application has the following advantages. The plurality of horizontal beams 3 are connected perpendicularly to the vertical beam 2 to form a stable support structure, so as to increase the strength of the frame 1; the connecting member is close to the tightly connected position between the two display screen supports to be spliced, and a large force is borne at this position, which can be borne and digested by the triangular reinforcing structure 4, so as to avoid the deformation of the display screen support and improve the service life of the display screen support.

[0050] In some embodiments, a controller for controlling the display screen is mounted on the vertical beam 2.

[0051] In some embodiments, a handle is mounted in the horizontal direction, which is used for moving the display screen support.

[0052] As shown in Figures 1-2 As an optional implementation, the reinforcing structure 4 shares a part with the frame 1, and the corner of the reinforcing structure 4 is connected with the horizontal beam 3.

[0053] With the above scheme, the reinforcing structure 4 in a triangular shape gradually narrows from the common part to the direction close to the cross beam 3, the wider part of the reinforcing structure 4 is close to the frame 1, and the wider part of the reinforcing structure 4 has a more stable bearing capacity relative to the narrower part. This arrangement can ensure better bearing effect.

[0054] As shown in Figures 1-2 As an optional embodiment, the frame 1 includes two first side beams 11 and two second side beams 12. The two first side beams 11 extend along a first direction and are spaced apart. The two second side beams 12 extend along a second direction and are spaced apart. The two second side beams 12 and the two first side beams 11 are connected end to end. The two second side beams 12 have a common part with the reinforcing structure 4, and at least part of the common part forms a connecting part 13 protruding along a third direction. The connecting part 13 is fixedly connected with the connecting piece. The first direction, the second direction, and the third direction are perpendicular to each other.

[0055] Based on the foregoing embodiment, in this embodiment, the two first side beams 11 are horizontally spaced apart, and the two second side beams 12 are vertically spaced apart.

[0056] The common part of the second side beam 12 and the reinforcing structure 4 is a part of the second side beam 12, which serves as an edge structure of the reinforcing structure 4. Not all reinforcing structures 4 are provided with connecting pieces, only the reinforcing structures 4 used for mounting the connecting pieces are provided with protruding connecting parts 13.

[0057] As an optional embodiment, the first side of the frame 1 is used to set the display screen, and the connecting part 13 protrudes from the second side of the frame 1. The first side and the second side are opposite.

[0058] Based on the foregoing embodiment, in this embodiment, the display screen and the connecting part 13 are located on different sides of the frame 1, and the connecting part 13 is arranged on the back side. In this way, the display screen is not blocked when displaying, ensuring the display effect.

[0059] As shown in Figure 2 As an optional embodiment, the connecting part 13 is in the form of a plate, and the connecting part 13 includes a bolt hole opened along the thickness direction for bolt connection with the connecting piece.

[0060] Based on the foregoing embodiment, in this embodiment, the connecting part 13 is perpendicular to the second side beam 12, and the connecting piece is arranged on the inner side of the connecting part 13 to be closer to the reinforcing structure 4.

[0061] As shown in Figures 1-2 As an optional embodiment, the display screen support further includes a positioning piece 5 fixedly connected with the reinforcing structure 4 and used to connect with other display screen supports.

[0062] Based on the foregoing embodiments, in this embodiment, the positioning member 5 is a plug rod which is bolted to the reinforcing structure 4. Part of the reinforcing structure 4 is connected to the positioning member 5 which is used to align two display screen supports. The positioning member 5 is connected to the adjacent display screen support, which is a tight connection, so the reinforcing structure 4 is needed to ensure the strength. The structure of the positioning member 5 of one display screen support and the other display screen support is a plug hole.

[0063] As shown in Figure 1 , as an optional embodiment, the plurality of reinforcing structures 4 are distributed at equal intervals.

[0064] The above scheme is adopted to uniformly distribute the reinforcing regions of the reinforcing structure 4, thereby improving the reinforcing effect.

[0065] As shown in Figures 1-2 , as an optional embodiment, the positioning member 5 is fixed to the reinforcing structure 4 in the middle; and the connecting member is fixed to the remaining reinforcing structures 4.

[0066] The above scheme is adopted to arrange the positioning member 5 in the middle and the connecting member in the part closer to the first side beam 11, thereby facilitating the alignment of the two display screen supports.

[0067] As an optional embodiment, the connecting member includes a curved surface adjusting member 6 of the display screen, and / or a locking member 7, and / or a clamping member 8.

[0068] As shown in Figures 3-17 , the curved surface adjusting member 6 of the display screen is used to adjust the included angle of the adjacent display screen support; the locking member 7 has a locking rod 71 which is used to lock with the curved surface adjusting member 6 of the display screen; and the clamping member 8 has an embedded hole 81 which is used to lock with the locking rod 71 of the locking member 7.

[0069] In some embodiments, the curved surface adjusting structure of the display screen mainly includes an adjusting seat 61, a sliding member 62, and a locking tongue 63. The adjusting seat 61 is fixed to one of the two adjacent display screen supports; the sliding member 62 is in sliding cooperation with the adjusting seat, the sliding track of the sliding member 62 is arc-shaped, and the sliding member 62 is provided with a locking hole 621 on the side away from the adjusting seat 61; the locking tongue 63 is provided with a clamping hole 631, the locking tongue 63 is inserted into the sliding member 62, the clamping hole 631 is in communication with the locking hole 621, and the locking tongue 63 moves relative to the sliding member 62 between a clamping position and an unlocking position.

[0070] More specifically, the adjusting seat 61 is bolted with the display screen support. The sliding member 62 is assembled to the adjusting seat 61, and the sliding member 62 can move along the arc relative to the adjusting seat 61. The driving of the sliding member 62 to move along the arc adjusts the relative positions of the sliding member 62 and the adjusting seat 61, and the angle of the locking of the locking rod 71 inserted into the locking hole 621, thereby changing the included angle formed by the two adjacent display screen supports, i.e. changing the arc of the display screen. The relative fixation of the sliding member 62 and the adjusting seat 61 is achieved through the clamping of the locking tongue 63 and the locking rod 71, so that the arc of the display screen is kept stable. Thus, the staff can adjust and fix the arc of the display screen according to the on-site requirements, thereby ensuring the applicability of the display screen.

[0071] The locking member 7 comprises a locking rod 71, a clamping groove 72, a connecting seat 73, a first spring 74 and a screw handle 75. The clamping groove 72 is arranged at one end of the locking rod 71, and the end of the locking rod 71 provided with the clamping groove 72 is inserted into the locking hole 621 and locked with the clamping hole 631 of the locking tongue 63. The connecting seat 73 is fixedly connected with the other one of the two adjacent display screen supports, and has an external thread segment and a limiting hole formed along the external thread segment; the locking rod 71 is arranged in the limiting hole; the first spring 74 is arranged in the limiting hole and sleeved outside the locking rod 71; and the screw handle 75 is threadedly connected with the connecting seat 73 and moves relative to the connecting seat 73 along the axial direction of the external thread segment to fasten the locking rod 71.

[0072] More specifically, the locking rod 71 of the locking member 7 moves along the axial direction thereof to relatively approach or move away from the sliding member 62, and the first end of the locking rod 71 has the clamping groove 72, which is inserted into the locking hole 621 and locked with the locking tongue 63 after being moved to the appropriate position. The connecting seat 73 comprises a base and an external thread segment connected with each other, and the base is provided with a threaded hole; and the connecting seat 73 is bolted with the other one of the two adjacent display screen supports. When the locking rod 71 is inserted into the locking hole 621 and locked with the clamping hole 631, the first spring 74 is compressed to accumulate elastic potential energy; and when the locking rod 71 is unlocked from the clamping hole 631, the first spring 74 releases the accumulated elastic potential energy to reset the locking rod 71. The rotation of the screw handle 75 controls the movement of the screw handle 75 away from the connecting seat 73, and the end of the screw handle 75 abuts against the end of the locking rod 71 to make the locking rod 71 more tightly clamped with the clamping hole 631, thereby preventing the locking rod 71 from loosening and making the connection more firm.

[0073] The clamping member 8 comprises a clamping seat 82 and a plug plate 83. The clamping seat 82 comprises an insertion groove 624 connected with the clamping hole 621, and the plug plate 83 is inserted into the insertion groove 624 and moves inwardly or outwardly relative to the insertion groove 624. The plug plate 83 is provided with an embedding hole 81.

[0074] The first end of the locking rod 71 of the locking member 7 is inserted into the clamping hole 621 and locked with the plug plate 83 after being moved to the appropriate position.

[0075] The locking cooperation of the locking member 7 and the locking tongue 63 is similar to the locking cooperation of the locking member 8 and the locking tongue 63, and the corresponding description can be referred to, and thus will not be described in detail.

[0076] In some embodiments, the curved adjustment structure of the display screen further comprises an adjustment member 64 connected with the sliding member 62; the adjustment seat 61 comprises a positioning tooth 611 extending in an arc shape; the adjustment member 64 is locked with the positioning tooth 611; the sliding member 62 and the adjustment seat 61 are relatively fixed; the adjustment member 64 is separated from the positioning tooth 611; the adjustment member 64 moves along the positioning tooth 611 to adjust the relative position of the sliding member 62 and the adjustment seat 61.

[0077] More specifically, when the adjustment member 64 is separated from the positioning tooth 611, i.e., the two are not connected, an external force acts on the adjustment member 64 to drive the sliding member 62 to move along the arc-shaped line to adjust the relative position of the sliding member 62 and the adjustment seat 61; after being adjusted to the appropriate position, the adjustment member 64 is locked with the positioning tooth 611 to keep the sliding member 62 and the adjustment seat 61 in a relatively fixed state.

[0078] In some embodiments, the adjustment seat 61 further comprises a housing 612, which has an arc-shaped sliding groove 613 inside; the sliding groove 613 is slidingly connected with the sliding member 62; one side of the housing 612 is provided with an adjustment hole 614 for the sliding groove 613 to communicate with the outside; the adjustment hole 614 extends in an arc shape, and the positioning tooth 611 is arranged along the edge of the adjustment hole 614; the adjustment member 64 is connected with the sliding member 62 in the sliding groove 613 from the outside of the housing 612 through the adjustment hole 614.

[0079] More specifically, the housing 612 comprises a groove housing 6121 and a sub-housing 6122; the rear side and the right side of the groove housing 6121 are provided with openings; the bottom of the groove housing 6121 (the front side of the groove housing 6121) is a curved structure extending in an arc shape; the sub-housing 6122 has a wall structure extending in an arc shape; the groove housing 6121 and the sub-housing 6122 are bolted; the wall structure of the sub-housing 6122 is assembled in the groove housing 6121; the wall structure of the sub-housing 6122 is arranged in a spaced-apart manner with the bottom of the groove housing 6121 to form the sliding groove 613; the sliding member 62 moves in and out of the right side opening of the groove housing 6121 in the sliding stage relative to the housing 612.

[0080] The bottom of the groove housing 6121 is provided with a long strip-shaped adjustment hole 614; the upper edge and the lower edge of the adjustment hole 614 are provided with the positioning tooth 611; part of the adjustment member 64 is located outside the housing 612, and the other part of the adjustment member 64 is connected with the sliding member 62 in the sliding groove 613 through the adjustment hole 614, so that the sliding member 62 can be driven to move relative to the adjustment seat 61 outside the housing 612.

[0081] In some embodiments, the sliding member 62 comprises a connecting curved portion 622 and a locking portion 623; the curved portion 622 extends in an arc shape, at least part of the curved portion 622 is fitted in the sliding groove 613, and the curved portion 622 is connected with the adjusting member 64; the locking portion 623 is provided with a locking hole 621, and the locking portion 623 is provided with a slot 624 which is in communication with the outside; along the axial direction of the locking hole 621, the slot 624 is located between the two openings of the locking hole 621 and is in communication with the locking hole 621; part of the locking tongue 63 is inserted into the slot 624, and the clamping hole 631 of the locking tongue 63 is clamped into the slot 624 and is in communication with the locking hole 621.

[0082] More specifically, the curved portion 622 and the locking portion 623 of the sliding member 62 are connected at an angle, the curved portion 622 is matched with the sliding groove 613, and the adjusting member 64 is located on the convex side of the curved portion 622. The locking portion 623 is block-shaped, and the locking portion 623 is located outside the sliding groove 613. The locking hole 621 penetrates through the locking portion 623, and the locking hole 621 is opposite to the concave side of the curved portion 622. The locking portion 623 is provided with the slot 624, and the opening of the slot 624 can face the front side. The locking tongue 63 is inserted into the slot 624 and can move inward or outward relative to the slot 624 to change the corresponding position of the clamping hole 631 and the locking hole 621.

[0083] In some embodiments, the sliding member 62 further comprises a resilient member 625 which is arranged in the slot 624 and abuts against the locking tongue 63; when the locking tongue 63 moves into the slot 624 to the unlocking position, the resilient member 625 is deformed to accumulate elastic potential energy; the resilient member 625 releases the accumulated elastic potential energy, and the locking tongue 63 moves out of the slot 624 to the locking position.

[0084] More specifically, no matter in the unlocking position or the locking position, the resilient member 625 is in a compressed state, and the difference is that the compression amount of the resilient member 625 is larger when the locking tongue 63 is in the unlocking position. Under the action of an external force, the locking tongue 63 moves into the slot 624, and the compression amount of the resilient member 625 increases; after the external force disappears, the resilient member 625 releases the accumulated elastic potential energy, and if the locking tongue 63 is in locking connection with the locking rod 71, the resilient member 625 provides the force for the clamping hole 631 to be clamped into the slot 624, and if the locking tongue 63 is separated from the locking rod 71, the locking tongue 63 moves out of the slot 624 to realize resetting.

[0085] In a specific embodiment, the resilient member 625 is a spring which is arranged between the bottom of the slot 624 and the locking tongue 63, the spring extends along the moving direction of the locking tongue 63 in the slot 624, one end of the spring abuts against the bottom of the slot 624, and the other end abuts against the front end of the first plate 632.

[0087] More specifically, an end of the first plate 632 away from the second plate 633 is the front end of the first plate 632, and an end of the first plate 632 connected with the second plate 633 is the rear end of the first plate 632. The front end of the first plate 632 is inserted into the slot 624, and the second plate 633 is located outside the slot 624; the first plate 632 and the second plate 633 are connected at an angle, and the second plate 633 forms a pressing part which is easy to press. The elastic member 625 is always in a compressed state, and the elastic member 625 always provides a force for the lock tongue 63 to move out of the slot 624; by pressing the second plate 633, the first plate 632 is driven to move into the slot 624 to achieve unlocking.

[0088] The clamping hole 631 is formed along the thickness direction of the first plate 632, and the clamping hole 631 comprises a first curved edge and a second curved edge connected with each other, and both the first curved edge and the second curved edge are part of the edge of a circular hole.
