Technical Field

[0001] This utility model relates to a lock, specifically an arc-shaped lock for an LED display body including a first movable handle, a second movable handle, and a toothed belt drive. The toothed belt drive is disposed between the first movable handle and the second movable handle, which are respectively connected to the LED display body.

[0002] As is well known, LED displays, as an image display device, are now widely used in various commercial display fields.

[0003] Traditional LED displays are generally composed of several LED cabinets spliced ​​together. Since the shape of the LED cabinets is rectangular, large LED displays composed of several LED cabinets spliced ​​together are generally also rectangular.

[0004] However, in practice, as users' requirements for display effects continue to increase, large rectangular LED displays can no longer meet their display needs. Against this backdrop, some manufacturers have adopted the method of assembling curved hardware brackets between LED cabinets to splice several LED cabinets into a large curved LED display. However, this connection method has many drawbacks, such as complex assembly and disassembly and high construction difficulty, which are the main shortcomings of the existing technology.

[0020] like Figures 1 to 12 As shown, an arc-shaped lock for an LED display screen includes a first movable handle 100, a second movable handle 200, and a toothed belt drive 300. The toothed belt drive 300 is disposed between the first movable handle 100 and the second movable handle 200. The first movable handle 100 and the second movable handle 200 are respectively connected to the LED display body 10. The toothed belt drive 300 can cause the first movable handle 100 and the second movable handle 200 to be displaced, thereby changing the shape of the LED display body 10.

[0021] In practice, the toothed belt drive 300 can cause the first moving handle 100 and the second moving handle 200 to produce an arc-shaped displacement.

[0022] The LED display body 10 is an LED display module or an LED display cabinet.

[0023] The toothed belt drive 300 includes a pulley 310 and a timing belt 320, wherein the pulley 310 is pivotally connected to the first moving handle 100, the timing belt 320 is connected to the second moving handle 200, and the pulley 310 and the timing belt 320 are engaged.

[0024] The pulley 310 reciprocates in the synchronous belt 320, and the first moving handle 100 moves synchronously with the pulley 310, so that the first moving handle 100 reciprocates relative to the second moving handle 200, thereby adjusting the relative position between the LED display body 10 on the first moving handle 100 and the second moving handle 200.

[0025] In specific implementation, the second movable handle 200 is provided with a motion platform 210, which has a motion trajectory end face 211. The two ends of the synchronous belt 320 are fixed to both sides of the motion trajectory end face 211, and a motion cavity 220 is formed by the synchronous belt 320 and the motion trajectory end face 211.

[0026] The pulley 310 is rolled in the motion cavity 220. The pulley 310 reciprocates in the motion cavity 220, causing the first moving handle 100 to reciprocate relative to the second moving handle 200.

[0027] In a specific implementation, the pulley 310 includes a gear portion 311 and a roller portion 312. The gear portion 311 meshes with the timing belt 320, and the roller portion 312 is rolled on the end face 211 of the motion track. When the first moving handle 100 reciprocates relative to the second moving handle 200, the pulley 310 rolls between the timing belt 320 and the end face 211 of the motion track.

[0028] In practice, a motion track 212 is provided on the end face 211 of the motion trajectory, and the roller portion 312 of the pulley 310 is rotatably mounted on the motion track 212.

[0029] In practice, the gear part 311 and the roller part 312 rotate coaxially. With the help of the synchronous belt 320, the internal pulling pressure of the gear part 311 causes the roller part 312 to roll and press onto the motion track 212.

[0030] The displacement trajectory between the first moving handle 100 and the second moving handle 200 is determined by the movement trajectory of the roller portion 312 on the motion track 212.

[0031] In practice, the motion track 212 is an arc-shaped track, and the roller portion 312 is rolled and pressed on the arc-shaped track, so that the first moving handle 100 can generate an arc-shaped displacement trajectory relative to the second moving handle 200.

[0032] In a specific implementation, the toothed belt drive 300 also includes a positioner 330, which includes a synchronous rotating shaft 331 and a positioning knob 332. The synchronous rotating shaft 331 is mounted on the pulley 310 and rotates synchronously with the pulley 310.

[0033] The positioning knob 332 includes a knob 333 and a pressure block 334. The synchronous rotating shaft 331 is located on one side of the pressure block 334, and the knob 333 is located on the other side of the pressure block 334. When it is necessary to fix the relative position between the first moving handle 100 and the second moving handle 200, the knob 333 is moved, and the knob 333 presses down on the pressure block 334, so that the pressure block 334 presses against the synchronous rotating shaft 331, thereby locking the pulley 310 and achieving the function of fixing the relative position between the first moving handle 100 and the second moving handle 200.

[0034] In practical implementation, the toothed belt drive 300 also includes an angle indicator 340, which includes an angle ruler 341, an angle marking portion 342, and an elastic locking head 343. The angle ruler 341 is disposed on the motion platform 210 of the second moving handle 200, and the angle marking portion 342 is disposed on the arc-shaped lock corresponding to the angle ruler 341. The angle marking portion 342 is exposed outside the arc-shaped lock and can be observed by the user.

[0035] The elastic locking head 343 is disposed in the first movable handle 100. The elastic locking head 343 corresponds to the angle ruler 341. The angle ruler 341 is provided with several angle grooves 344. The elastic locking head 343 is switched and locked between several angle grooves 344.

[0036] Once the relative position between the first movable handle 100 and the second movable handle 200 is determined, the elastic locking head 343 engages in an angle groove 344. At this moment, the angle information between the first movable handle 100 and the second movable handle 200 is displayed to the user through the angle marking portion 342.

[0037] In a specific implementation, the toothed belt drive 300 also includes an auxiliary limiting structure 350, which includes a first handle limiter 351 and a second handle limiter 352, wherein the first handle limiter 351 is disposed on the first moving handle 100.

[0038] The second handle limiter 352 is disposed on the second movable handle 200. The first handle limiter 351 moves within the second handle limiter 352, so that when the first movable handle 100 and the second movable handle 200 are displaced, the auxiliary limiting structure 350 can help limit the movement trajectory between them.

[0039] In practice, there are various structures that can achieve the function of this auxiliary limiting structure 350, such as the structure of the slot and the pin, the structure of the track and the roller, etc.

[0040] In a specific implementation, the toothed belt drive 300 also includes an angle limiting structure 360, which is used to limit the maximum displacement between the first moving handle 100 and the second moving handle 200. The angle limiting structure 360 ​​includes a plurality of limit bolts 361, which are disposed in the first handle limiter 351.

[0041] When the second handle limiter 352 moves within the first handle limiter 351, the limit bolt 361 limits the maximum displacement of the second handle limiter 352 within the first handle limiter 351, thereby limiting the maximum displacement between the first moving handle 100 and the second moving handle 200.

[0042] In specific implementation, the first movable handle 100 includes a rotating handle 110, and the pulley 310 is connected to the rotating handle 110. The pulley 310 and the rotating handle 110 rotate coaxially. The user can rotate the rotating handle 110 and the pulley 310 synchronously to make the first movable handle 100 and the second movable handle 200 displaced, so as to change the shape of the LED display body 10.

[0043] In practical implementation, the toothed belt drive 300 is respectively installed at the upper and lower ends of the arc-shaped lock, wherein the pulley 310 is coaxially connected to the upper and lower ends of the rotating handle 110.
