It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0045] This application provides a display screen, which includes a frame and an arc lock disposed on the frame. The arc lock is used to lock or unlock two adjacent display screens. The locking angle of the arc lock is adjustable so that the two adjacent display screens are at a preset angle, so that multiple display screens can be spliced ​​together to form a large curved screen to obtain a good viewing experience for users.

[0046] One possible structure for the arc lock includes an arc adjustment lock base 1 and a locking groove device that locks or unlocks the arc adjustment lock base 1. One of the two opposing side frames 2 on the frame has a locking groove device, and the other has an arc adjustment lock base 1. When two adjacent displays are spliced ​​together, the side frame 2 of one display abuts against the side frame 2 of the other display through the arc adjustment lock base 1. The locking groove device on the side frame 2 of the other display can cooperate with the arc adjustment lock base 1 to lock and achieve the connection between the two adjacent displays. Adjusting the angle of the abutment surface 111 between the arc adjustment lock base 1 and the side frame 2 of the other display adjusts the locking angle of the arc lock.

[0047] Specifically, please refer to Figures 1-2 As shown in some embodiments of this application, the arc adjustment lock base 1 includes a splicing block 11 and a locking pin 12. The splicing block 11 has an abutment surface 111, and the locking pin 12 is slidably disposed on the splicing block 11, having a first position protruding from the abutment surface 111 and a second position retracted into the splicing block 11. The side frame 2 is provided with a mounting groove 21, and the splicing block 11 is rotatably disposed in the mounting groove 21 of the side frame 2. The abutment surface 111 protrudes from the side frame 2 and abuts against another side frame 2. Since the abutment surface 111 protrudes from the side frame 2, when two adjacent displays are spliced, they abut against the side frame 2 of another display through the abutment surface 111. Rotating the splicing block 11 can adjust the angle of the abutment surface 111 so that the angle of the abutment surface 111 is a preset angle between the two adjacent displays, thereby making the locking angle of the arc lock adjustable. The angle adjustment of the arc adjustment lock base 1 can be achieved by rotation, which is simple and quick to operate.

[0048] Further, please refer to Figures 1-2As shown in the embodiment of this application, the arc adjustment lock seat 1 further includes a toothed block 13. One side of the toothed block 13 is disposed on the side frame 2, and the other side is a first arc surface 131 coaxial with the rotation axis of the splicing block 11. A plurality of locking teeth 132 are spaced apart on the first arc surface 131. The splicing block 11 is provided with a limiting tooth 113. The limiting tooth 113 can engage with the locking tooth 132 at any position. When the splicing block 11 is rotated and the abutment surface 111 is rotated to a preset angle, the limiting tooth 113 engages with the locking tooth 132 at the corresponding position, which can limit the position of the splicing block 11, so that the splicing block 11 is fixed at the adjusted angle position and will not be changed by external force.

[0049] Please refer to Figures 1-2 As shown, as a feasible structure, there are two toothed blocks 13. The mounting groove 21 has stepped structures 23 on both sides along the length of the frame. Each stepped surface of the stepped structure 23 has a toothed block 13. The splicing block 11 has a mounting platform 112 protruding from the side opposite to the mounting groove 21 along the length of the frame. The mounting platform 112 corresponds to the stepped structure 23. The limiting tooth 113 is set on the mounting platform 112. The toothed blocks 13 on both sides of the splicing block 11 can limit both sides of the splicing block 11 when it rotates to a preset angle, so that the splicing block 11 is stably limited and will not displace, thus ensuring the accuracy of the angle of the contact surface 111.

[0050] In some embodiments of this application, please refer to Figures 1-2As shown, the arc adjustment lock seat 1 also includes a pressure plate 14, an adjusting member 15, and a first reset member 16. The pressure plate 14 abuts against the side of the splicing block 11 away from the toothed block 13, that is, the pressure plate 14 is located on the side of the splicing block 11 away from the mounting groove 21. The adjusting member 15 passes through the pressure plate 14 and connects to the side frame 2. The connection length between the adjusting member 15 and the side frame 2 is adjustable so that the pressure plate 14 has a locking position abutting against the side frame 2 and an adjustment position with a gap from the side frame 2. When the pressure plate 14 is in the adjustment position, the splicing block 11 can be moved toward the pressure plate, thereby separating the limiting tooth 113 from the locking tooth 132. At this time, the splicing block 11 can be rotated to adjust the angle of the abutting surface 111. When the pressure plate 14 is in the locking position, the pressure plate 14 presses the splicing block 11 tightly, and the limiting tooth 113 and the locking tooth 132 cannot disengage. At this time, the splicing block 11 is limited and cannot be rotated. Optionally, the adjusting component 15 is an adjusting screw. The screw rod passes through the pressure plate 14 and is screwed onto the side frame 2. The connection length between the adjusting screw and the side frame 2 can be adjusted by turning the adjusting screw. The structure is simple and the operation is convenient. One end of the first reset component 16 is set on the side of the splicing block 11 away from the pressure plate 14. Corresponding to the first reset component 16, the side frame 2 is provided with a second arc surface 114 coaxial with the rotation axis of the splicing block 11. That is, the groove wall of the mounting groove 21 is provided with a second arc surface 114. The other end of the first reset component 16 can slide and abut against the second arc surface 114. When the pressure plate 14 is in the locked position, the locking tooth 132 engages with the limiting tooth 113, and the first reset component 16 is compressed. When the pressure plate 14 is in the adjusted position, under the action of the elastic force of the first reset component 16, the abutting block and the pressure plate 14 move in the direction away from the mounting groove 21, so that the locking tooth 132 and the limiting tooth 113 are separated. Therefore, when it is necessary to adjust the angle of the abutment surface 111, simply adjust the connection length between the adjusting member 15 and the side frame 2, and the locking tooth 132 and the limiting tooth 113 will automatically separate. There is no need to manually move the abutment block in the direction away from the mounting groove 21, saving operation steps, simplifying the operation process, and making it more convenient.

[0051] Please refer to Figures 1-2As shown, as an optional solution, the first reset member 16 includes a spring and a ball bearing. One end of the spring is connected to the splicing block 11, and the ball bearing is rotatably located at the other end of the spring. The ball bearing abuts against the second arc surface 114. When the splicing block 11 rotates, the ball bearing can slide on the second arc surface 114 to reduce friction and facilitate the rotation of the splicing block 11. When the pressure plate 14 is in the locked position, the spring is compressed, and when the pressure plate 14 is in the adjusted position, the spring is in its natural state. In some embodiments of this application, there is at least one first reset member 16, and there can be two or more, to ensure the smoothness of sliding on the second arc surface 114. Preferably, there are two first reset members 16, which can ensure smoothness and reduce the force required for the splicing block 11 to move toward the mounting groove 21, avoiding the difficulty in locking the splicing block 11 due to excessive compression force of all the first reset members 16.

[0052] Please refer to Figures 1-2 As shown, in some embodiments of this application, the side of the pressure plate 14 facing the other side frame 2 is flush with the side of the side frame 2 it is located on, and is provided with a display hole 141. The side of the splicing block 11 that abuts against the pressure plate 14 is a third arc surface 22 that is coaxial with the rotation axis of the splicing block 11. The side of the third arc surface 22 facing the other side frame 2 is provided with a scale mark 115, which is aligned with the display hole 141. Since the third arc surface 22 is coaxial with the rotation axis of the splicing block 11, when the splicing block 11 rotates, the third arc surface 22 rotates by the same angle. Therefore, the scale mark 115 seen through the display hole 141 is the angle of rotation of the abutment surface 111. When rotating the splicing block 11, the operator can know the current angle of the abutment surface 111 by looking at the scale mark 115 through the display hole 141, making it convenient for the operator to adjust the angle of the arc lock.

[0053] Please refer to Figures 1-2 As shown, in some embodiments of this application, the arc adjustment lock seat 1 further includes a pin 18, which passes through the splicing block 11. The locking pin 12 has a circumferential groove 1221 along the axis of the pin 18. One end of the pin 18 is accommodated in the groove 1221 and can slide along the groove 1221. The side frame 2 has an arc groove 24 corresponding to the pin 18 and coaxial with the rotation axis of the splicing block 11. The other end of the pin 18 can be slidably disposed in the arc groove 24. When the splicing block 11 is rotated, one end of the pin 18 slides in the arc groove 24, and the pin 18 can restrict the splicing block 11 within the mounting groove 21, preventing the splicing block 11 from detaching from the mounting groove 21. When the locking pin 12 switches between the first position and the second position, the end of the locking pin 12 away from the arc groove 24 can slide in the slide groove 1221. The groove walls at both ends of the slide groove 1221 restrict the displacement of the locking pin 12 in the slide groove 1221, preventing the pin 18 from disengaging from the splicing block 11.

[0054] Further, please refer to Figures 1-2As shown, in some embodiments of this application, the width of the slide groove 1221 is greater than the diameter of the pin 18, and the difference between the width of the slide groove 1221 and the diameter of the pin 18 is greater than or equal to the stroke value of the first reset member 16, so that when the splicing block 11 moves in a direction away from the mounting groove 21, the pin 18 can move accordingly in the slide groove 1221 to avoid interference of the pin 18.

[0055] Please refer to Figures 1-2 As shown, one possible structure of the locking pin 12 is as follows: the locking pin 12 includes a locking end 121, a middle section 122, and an operating end 123 connected in sequence. The middle section 122 has sliding grooves 1221 on both sides along the length of the side frame 2. The pin 18 is correspondingly positioned with each sliding groove 1221, thereby ensuring the stability of the sliding of the splicing block 11 and preventing deviation. The locking end 121 includes a limiting head 1211 and a sliding section 1212. The diameter of the limiting head 1211 is larger than the diameter of the sliding section 1212 and is located on the side of the sliding section 1212 away from the middle section 122. When the locking pin 12 is in the first position, the locking end 121 is inserted into the locking groove device, which can engage the limiting head 1211 to achieve the locking of the arc lock. The operating end 123 includes a boss 1231 and an operating handle 1232. The diameter of the boss 1231 is larger than the diameter of the operating handle 1232. The operating handle 1232 is located on the side of the boss 1231 away from the middle section 122. The diameter of the boss 1231 is also larger than the diameter of the hole through which the locking pin 12 passes on the splicing block 11, thereby restricting the locking pin 12 from dislodging from the hole when it moves along the splicing block 11.

[0056] Please refer to Figures 1-2 As shown, in some embodiments of this application, the arc adjustment lock seat 1 further includes a second reset member 19. The second reset member 19 is sleeved on the pin 18, with one end abutting against the surface of the boss 1231 and the other end abutting against the pin 18. When the locking pin 12 is in the first position, the second reset member 19 is compressed, and the locking pin 12 can be locked in the locking groove device. When the locking groove device is unlocked from the arc adjustment lock seat 1, the locking pin 12 automatically switches from the first position to the second position under the elastic force of the second reset member 19, thereby reducing the operation steps and making the unlocking process more convenient.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
