Description

Technical Field

[0001] This invention relates to the field of display screen technology, and in particular to a display screen curvature lock. Background Technology

[0002] LED displays typically have a large display area, and are assembled from small unit modules to meet production, transportation, and maintenance requirements. During assembly, these unit modules require connecting mechanisms. For displays used in rental applications, the assembly mechanism must be fast and adaptable to various curved surfaces. Currently, most curved locking mechanisms use a curved sliding guide rail. However, curved surfaces require precision machining to achieve vertical splicing accuracy. Since the curved guide rail needs adjustment, the gap directly affects the splicing accuracy of the locking mechanism in all directions (front, back, left, right, up, and down). Precision machining of curved surfaces is very difficult, resulting in high costs.

[0003] For example, Chinese invention patent application 202211304168.2 discloses an LED curved splicing display screen, which has a curved locking component. However, its structure is complex, its processing and assembly are difficult, and its splicing accuracy of unit modules is difficult to control. Summary of the Invention

[0026] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0027] Example 1:

[0028] like Figures 1-13 As shown, this invention discloses a display screen arc lock, including a locking seat 1 and an angle slider 2. The locking seat 1 has an arc surface with an elongated hole 8. A first angle stop serration 11 is provided on one or both sides of the elongated hole 8. The angle slider 2 also has an arc surface, which is connected to the arc surface of the locking seat 1. A second angle stop serration 12 is provided on the angle slider 2, which is connected to the first angle stop serration 11. A locking screw 7 is rotatably connected to the angle slider 2, passing through the elongated hole 8. A locking nut 5 is provided on the locking screw 7 on the other side of the elongated hole 8. The locking screw 7 and the locking nut 5 are used to press the locking seat 1 and the angle slider 2 together. The locking seat 1 and the angle slider 2 are respectively connected to two spliced ​​display screens 15.

[0029] The locking seat 1 has a connecting hole, which can be fixed to one of the display screens 15 with bolts. The angle slider 2 is also fixed to the other display screen 15. The connection between the angle slider 2 and the display screen 15 can be bolted or quick-connected. That is, a connector 16 is provided on the other display screen 15, and the connector 16 is quickly connected to the angle slider 2 through a buckle or connecting rod 17. The locking seat 1 and the angle slider 2 are provided with a first angle stop sawtooth 11 and a second angle stop sawtooth 12, and are connected and pressed together by a screw and a locking nut 5. After pressing, the locking seat 1 and the angle slider 2 are glued together between the first angle stop sawtooth 11 and the second angle stop sawtooth 12 to achieve positioning. The arc surface on the locking seat 1 and the arc surface on the angle slider 2 have the same curvature. Their cooperation allows for rotation. When the locking seat 1 and angle slider 2 are connected to the display screen 15, their rotation axis can be the seam where the two display screens 15 are joined, thus enabling rotation between the display screens 15 and angle adjustment between adjacent display screens 15. The range of angle adjustment can be determined by the arc length of the locking seat 1 and angle slider 2, generally reaching a maximum adjustment range of 90°. The fineness of adjustment between the locking seat 1 and angle slider 2, i.e., the minimum adjustment angle, is one tooth pitch of the first angle setting serration 11 and the second angle setting serration 12. A reasonable tooth pitch can be selected and set according to actual needs.

[0030] A V-shaped concave structure 9 is provided on the arc surface of the locking seat 1, and the elongated hole 8 is provided at the bottom of the V-shaped concave structure 9. The first angle stop serration 11 is provided on the two side walls 3 of the V-shaped concave structure 9. A V-shaped protruding structure 10 is provided on the arc surface of the angle slider 2, and the second angle stop serration 12 is provided on the two side walls 3 of the V-shaped protruding structure 10. This design allows for automatic positioning when the locking seat 1 and the angle slider 2 are locked after each adjustment, ensuring that the positions of the locking seat 1 and the angle slider 2 remain unchanged in the width direction, resulting in high splicing accuracy between the display screen 15. The V-shaped concave structure 9 and the V-shaped protruding structure 10 can be processed using molds, greatly reducing processing costs and improving performance.

[0031] A screw hole is provided on the angle slider 2, and the locking screw 7 is connected to the screw hole. A handle 6 is provided at the end of the locking screw 7 outside the angle slider 2. An elongated space is required on the locking seat 1 behind the elongated hole 8 to accommodate the locking nut 5. During the adjustment of the locking screw 7 within the elongated hole 8, the locking nut 5 can move within the elongated space. Preferably, the outer wall of the locking nut 5 is a non-circular structure, and the outer wall of the locking nut 5 can contact the side wall 3 of the locking seat 1 in the elongated space. In this way, during the rotation of the locking screw 7, the position of the locking nut 5 is limited and it will not rotate synchronously with the locking screw 7. Therefore, the operation is simple, convenient, and highly reliable.

[0032] The threads at both ends of the locking screw 7 are in opposite directions, and the screw hole and locking nut 5 are respectively engaged with the threads in different directions on the locking screw 7. This design allows for faster locking and unlocking between the locking seat 1 and the angle slider 2 when the locking screw 7 is rotated, improving operational efficiency.

[0033] Side walls 3 are provided on both sides of the angle slider 2, and an end wall 4 is provided at one end of the angle slider 2. The end wall 4 is connected to the side wall 3, and a connecting hole is provided on the end wall 4 for connecting the display screen 15.

[0034] With the addition of sidewall 3 and endwall 4, the connection between sidewall 3 and angle slider 2 is more robust and stable. As a result, angle slider 2 is also more robust and reliable after being connected to display screen 15 via endwall 4.

[0035] A through hole is provided on the V-shaped protrusion structure 10 of the angle slider 2. The two ends of the through hole are located within the range of the second angle setting sawtooth 12. A compression spring 14 is provided inside the through hole, and steel balls 13 are provided in the through holes at both ends of the compression spring 14. With the setting of the compression spring 14 and the steel balls 13, when the relative position of the angle slider 2 and the locking seat 1 is adjusted, when both are displaced by one tooth pitch, the compression spring 14 will press the steel balls 13 into the corresponding tooth grooves. Therefore, when the angle slider 2 is moved, the number of tooth pitches adjusted can be felt, making the adjustment more precise.

[0036] The through hole is located at the corresponding position of one of the teeth of the second angle gear 12. By setting the through hole at the tooth, when the steel ball 13 is pressed into the corresponding groove, the groove of the first angle gear 11 corresponds to the tooth of the second angle gear 12, making the adjustment more accurate and reliable.

[0037] Of course, an angle scale can also be set on the upper surface of the angle slider 2, and a viewing hole can be set on the angle slider 2 at the edge of the angle scale, with the viewing hole passing through the angle slider 2. A scale indicator block can be set on the locking seat 1. During the relative adjustment process between the locking seat 1 and the angle slider 2, the angle scale corresponding to the scale indicator block is the angle of the two corresponding displays 15, making the adjustment process more intuitive.
