[0039] As Figures 1-13 shown, the present application provides a curved surface adjusting structure of a display screen, mainly comprising an adjusting seat 1, a sliding member 2, a latching member 3 and a locking member 4. The adjusting seat 1 is fixed to one of two adjacent display screen housings; the sliding member 2 is in sliding cooperation with the adjusting seat 1, the sliding track of the sliding member 2 is arc-shaped, and the sliding member 2 is provided with a locking hole 21 on the side away from the adjusting seat 1; the latching member 3 is provided with a latching hole 31, the latching member 3 is inserted into the sliding member 2, the latching hole 31 is in communication with the locking hole 21, and the latching member 3 moves relative to the sliding member 2 between a latching position and an unlocking position; the locking member 4 is fixed to the other of the two adjacent display screen housings, and the locking member 4 comprises a locking rod 41, one end of the locking rod 41 is provided with a latching slot 42, and the end of the locking rod 41 provided with the latching slot 42 is inserted into the locking hole 21 and latches with the latching hole 31 of the latching member 3.

[0040] In the embodiment, the adjusting seat 1 and the locking member 4 are arranged on the back side of the display screen box, i.e. the side opposite to the display screen, and are bolted to the display screen box. The sliding member 2 is assembled to the adjusting seat 1 and can move along the arc relative to the adjusting seat 1.

The relative fixation of the sliding member 2 and the adjusting seat 1 is realized through the clamping of the locking member 3 and the locking rod 41, so as to keep the curvature of the display screen stable. Therefore, the curvature of the display screen can be adjusted and fixed according to the on-site demand by the staff, so as to ensure the applicability of the display screen.

[0042] As shown in FIGS. Figure 1 , 9 , 10 and 11, as an optional embodiment, the curved surface adjusting structure of the display screen further comprises an adjusting member 5 connected with the sliding member 2. The adjusting seat 1 comprises a positioning tooth 11 extending in an arc shape. The adjusting member 5 is locked and connected with the positioning tooth 11, and the sliding member 2 and the adjusting seat 1 are fixed relative to each other.

[0043] Based on the foregoing embodiment, in the embodiment, when the adjusting member 5 is separated from the positioning tooth 11, i.e. the two are not connected, an external force is applied to the adjusting member 5 to drive the sliding member 2 to move along the arc, so as to adjust the relative positions of the sliding member 2 and the adjusting seat 1. After being adjusted to the appropriate position, the adjusting member 5 is locked and connected with the positioning tooth 11 to keep the relative fixed state of the sliding member 2 and the adjusting seat 1.

[0044] As shown in FIG. Figures 1-3 , as an optional embodiment, the adjusting seat 1 further comprises a housing 12, and the housing 12 is internally provided with a sliding groove 13 extending in an arc shape. The sliding groove 13 is slidingly connected with the sliding member 2. An adjusting hole 14 is formed in one side of the housing 12 and is used for connecting the sliding groove 13 with the outside. The adjusting hole 14 extends in an arc shape, and the positioning tooth 11 is arranged along the edge of the adjusting hole 14. The adjusting member 5 is connected with the sliding member 2 in the sliding groove 13 from the outside of the housing 12 through the adjusting hole 14.

[0045] Based on the foregoing embodiments, in this embodiment, the housing 12 includes a slotted shell 121 and a sub-shell 122. The slotted shell 121 has openings on its rear and right sides, and the bottom (front side) of the slotted shell 121 is a curved structure extending in an arc. The sub-shell 122 has a curved wall structure. The slotted shell 121 and the sub-shell 122 are bolted together. The wall structure of the sub-shell 122 is fitted inside the slotted shell 121, and the wall structure of the sub-shell 122 is spaced apart from the bottom of the slotted shell 121 to form a sliding groove 13. During the sliding phase relative to the housing 12, the sliding member 2 slides into or out of the opening on the right side of the slotted shell 121.

[0046] The bottom of the housing 121 is provided with an elongated adjustment hole 14, and the upper and lower edges of the adjustment hole 14 are provided with positioning teeth 11. One part of the adjustment component 5 is located outside the housing 12, and the other part of the adjustment component 5 passes through the adjustment hole 14 and is connected to the sliding component 2 in the sliding groove 13. In this way, the sliding component 2 can be driven to move relative to the adjustment seat 1 from the outside of the housing 12.

[0047] like Figures 4-5 As shown in Figure 8, as an optional embodiment, the sliding member 2 includes a curved portion 22 and a locking portion 23 connected to each other; the curved portion 22 extends in an arc shape, and at least a portion of the curved portion 22 is fitted into the sliding groove 13, and the curved portion 22 is connected to the adjusting member 5; the locking portion 23 has a locking hole 21 and a slot 24 communicating with the outside; along the axial direction of the locking hole 21, the slot 24 is located between the two openings of the locking hole 21 and communicates with the locking hole 21; a portion of the locking member 3 is inserted into the slot 24, and the locking hole 31 of the locking member 3 is engaged in the slot 24 and communicates with the locking hole 21.

[0048] Based on the aforementioned embodiments, in this embodiment, the curved portion 22 and the locking portion 23 of the sliding member 2 are connected at an angle. The curved portion 22 is adapted to the sliding groove 13, and the adjusting member 5 is located on the convex side of the curved portion 22. The locking portion 23 is block-shaped and located outside the sliding groove 13. The locking hole 21 passes through the locking portion 23 and is opposite to the concave side of the curved portion 22. The locking portion 23 has a slot 24, the opening of which can face forward. The locking member 3 is inserted into the slot 24 and can move inward or outward relative to the slot 24 to change the corresponding position of the locking hole 31 and the locking hole 21.

[0049] like Figures 4-6 As shown in Figure 8, as an optional implementation, the sliding member 2 further includes an elastic member 25, which is disposed in the slot 24 and abuts against the locking member 3; the locking member 3 moves into the slot 24 to the unlocked position, and the elastic member 25 deforms to accumulate elastic potential energy; the elastic member 25 releases the accumulated elastic potential energy, and the locking member 3 moves out of the slot 24 to the locking position.

[0050] Based on the foregoing embodiments, in the present embodiment, the elastic member 25 is in a compressed state regardless of whether the catch piece 3 is in the unlocked position or the latched position, the difference being that the compression amount of the elastic member 25 is greater when the catch piece 3 is in the unlocked position. Under the action of an external force, the catch piece 3 moves into the slot 24, and the compression amount of the elastic member 25 increases; after the external force disappears, the elastic member 25 releases the accumulated elastic potential energy, and if the catch piece 3 is in locked connection with the lock rod 41, the elastic member 25 provides the force for the catch hole 31 to be latched into the slot 24, and if the catch piece 3 is separated from the lock rod 41, the catch piece 3 moves out of the slot 24 to achieve resetting.

[0051] In one specific embodiment, the elastic member 25 is a spring, which is arranged between the bottom of the slot 24 and the catch piece 3, extends along the moving direction of the catch piece 3 in the slot 24, and abuts against the bottom of the slot 24 at one end and against the front end of the first plate 32 at the other end.

[0052] As shown in Figure 7 As an optional implementation, the catch piece 3 includes the first plate 32 and the second plate 33 connected at an angle; the first plate 32 is inserted into the slot 24, the first plate 32 is provided with the catch hole 31, and the catch hole 31 is a special-shaped hole; and the second plate 33 is arranged outside the slot 24 as a force structure of the external force.

[0053] Based on the foregoing embodiments, in the present embodiment, the end of the first plate 32 away from the second plate 33 is the front end of the first plate 32, and the end of the first plate 32 connected with the second plate 33 is the rear end of the first plate 32. The front end of the first plate 32 is inserted into the slot 24, the second plate 33 is located outside the slot 24, the first plate 32 and the second plate 33 form a 90-degree angle, and the second plate 33 forms a pressing portion that is easy to press. The elastic member 25 is always in a compressed state, and the elastic member 25 always provides a force for the catch piece 3 to move out of the slot 24, and by pressing the second plate 33, the first plate 32 is driven to move into the slot 24 to achieve unlocking.

[0054] The lock rod 41 is a rod structure with a circular cross section, and the catch groove 42 is radially recessed in the head end of the lock rod 41. The catch hole 31 is provided along the thickness direction of the first plate 32, and the catch hole 31 includes the first curved edge and the second curved edge connected with each other, and the first curved edge and the second curved edge are both part of the edge of a circular hole. The lock hole 21 is misaligned with the catch hole 31, and the head end of the lock rod 41 is in contact with the catch hole 31 during the movement of the lock rod 41 along its own axis to drive the catch piece 3 to move into the slot 24, and after the catch piece 3 moves inward to an appropriate position, the second curved edge is latched into the catch groove 42 to achieve locking of the catch piece 3 with the lock rod 41.

[0055] As shown in Figures 12-13As shown, in an optional embodiment, the locking component further includes a connecting seat 43, a first spring 44, and a screw handle 45. The connecting seat 43 is fixedly connected to another of the two adjacent display screen housings. The connecting seat 43 has an external thread section, and a limiting hole is formed along the external thread section. The locking rod 41 passes through the limiting hole. The first spring 44 is disposed in the limiting hole and sleeved on the outside of the locking rod 41. The screw handle 45 is threadedly connected to the connecting seat 43, and the screw handle 45 moves relative to the connecting seat 43 along the axial direction of the external thread section to fasten the locking rod 41.

[0056] Based on the aforementioned embodiments, in this embodiment, the connecting seat 43 includes a connected base and an external threaded section. The base has a threaded hole, and the connecting seat 43 is connected to another bolt in one of the two adjacent display screen housings. When the locking rod 41 extends into the locking hole and locks into the locking hole 31, the first spring 44 compresses and accumulates elastic potential energy. After the locking rod 41 unlocks from the locking hole 31, the first spring 44 releases the accumulated elastic potential energy, causing the locking rod 41 to return to its original position. Rotating the screw handle 45 controls the screw handle 45 to move away from the connecting seat 43. The screw handle 45 presses against the end of the locking rod 41, making the locking rod 41 more tightly engaged with the locking hole 31, preventing the locking rod 41 from loosening, and making the connection more secure.

[0057] like Figures 9-11 As shown, in one optional implementation, the adjusting member 5 includes a positioning member 51, a connecting rod 52, a second spring 53, and a cam handle 54. The positioning member 51 includes a positioning part 511 and a plug-in part 512 connected together, and a through hole 513 passing through the positioning part 511 and the plug-in part 512; the plug-in part 512 passes through the adjustment hole 14 and is embedded in the sliding member 2; the positioning part 511 is disposed on the outside of the housing 12, and a toothed part 514 for cooperating with the positioning tooth 11 is provided on the side of the positioning part 511 near the plug-in part 512; the connecting rod 52 passes through the through hole 513 and is inserted into the sliding member 2; the second spring 53 is sleeved on the outside of the connecting rod 52; one end of the second spring 53 abuts against the sliding member 2, and the other end abuts against the plug-in part 512 or the positioning part 511; the cam handle 54 has a curved surface with different curvature at the first end and a handle at the second end; the first end of the cam handle 54 is rotatably connected to the end of the connecting rod 52 near the positioning member 51, and the cam handle 54 rotates relative to the connecting rod 52 in the unlocking direction or the locking direction.

[0058] Based on the aforementioned embodiments, in this embodiment, both the positioning part 511 and the insertion part 512 are block-shaped. The insertion part 512 passes through the adjustment hole 14 and is connected to the sliding member 2. The positioning part 511 is located on the outside of the adjustment seat 1. The positioning part 511 protrudes from the insertion part 512 in the upper and lower directions. The portion of the positioning part 511 that protrudes from the insertion part 512 is provided with teeth 514 facing the positioning teeth 11.

[0059] One end of the connecting rod 52 inserted into the sliding member 2 is designated as the first end, and the end of the connecting rod 52 near the positioning member 51 is designated as the second end. The first end of the connecting rod 52 is provided with an outward protrusion extending in a direction perpendicular to its own axis, and the second end of the connecting rod 52 is provided with a through hole penetrating in a direction perpendicular to its own axis. The rotating shaft passes through the through hole of the connecting rod 52 and the first end of the cam handle 54 to realize the rotatable connection between the cam handle 54 and the connecting rod 52.

[0060] When an external force actuates the handle of the cam handle 54, the cam handle 54 rotates in the locking direction, and the positioning member 51 moves closer to the sliding member 2, thereby locking the tooth 514 with the positioning tooth 11. The second spring 53 deforms and accumulates elastic potential energy. When the cam handle 54 rotates in the unlocking direction, the second spring 53 releases the accumulated elastic potential energy, and the positioning member 51 moves away from the sliding member 2, thereby separating the tooth 514 from the positioning tooth 11.

[0061] like Figures 9-11 As shown, in an optional embodiment, the sliding member 2 is provided with a mounting groove 26 on the side near the adjustment hole 14. The mounting groove 26 is recessed in the direction away from the adjustment hole 14. A mounting hole 27 is provided on the side of the mounting groove 26 opposite to the adjustment hole 14. The mounting hole 27 is connected to the mounting groove 26. The connecting rod 52 passes through the through hole 513 and the mounting hole 27 to be inserted into the sliding member 2.

[0062] Based on the aforementioned embodiments, in this embodiment, the insertion part 512 of the positioning member 51 is adapted to the mounting groove 26, and the insertion part 512 of the positioning member 51 is inserted into the mounting groove 26. With the above solution, the connecting rod 52 provides sufficient support for the rotation of the cam handle 54; when the positioning member 51 is close to or far away from the adjusting seat 1, the connecting rod 52 can play a precise guiding role.
