Description

Technical Field

[0001] This utility model relates to the field of LED light guide plate processing technology, and in particular to an LED light guide plate splicing device with positioning function. Background Technology

[0002] With the advancement of LED (Light Emitting Diode) technology and its widespread application in the display field, LED displays have become an indispensable part of many industries, including advertising media, stage performances, and information display. LED displays are typically large screens assembled from multiple small light guide plates. Traditional LED light guide plate splicing requires positioning to ensure accuracy. Traditional positioning structures are usually fixed frames. While this method provides some stability, it lacks flexibility for different application scenarios. Some specially shaped LED displays require angled splicing, which existing fixed splicing structures cannot meet.

[0003] To address the aforementioned issues, we propose an LED light guide plate splicing device with positioning functionality. This splicing device allows for free adjustment of the splicing angle and height to meet different scene and design requirements. Summary of the Invention

[0004] To overcome the shortcomings of fixed positioning frames that cannot be adjusted according to scene and shape requirements, this utility model provides an LED light guide plate splicing device with positioning function. This splicing device can freely adjust the splicing angle and height to meet different scene and shape requirements.

[0005] The technical solution of this utility model is as follows: an LED light guide plate splicing device with positioning function, including a fixed base, a mounting base fixedly connected to the top of the fixed base, a horizontally corresponding positioning frame rotatably connected to the mounting base, an LED light guide plate placed in the positioning frame, and a first rack fixedly connected to one side of the positioning frame. A longitudinally symmetrical adjustment motor is fixedly connected to the mounting base, and a second rack is fixedly connected to the positioning frame on the other side. A gear is fixedly connected to the output shaft of the adjustment motor. A lifting plate is slidably connected in the positioning frame, and an electric push rod is fixedly connected to the positioning frame. The telescopic end of the electric push rod is fixedly connected to the adjacent lifting plate. A fixing component is provided on the fixed base to fix the fixed base in a designated position. A reading component for displaying the rotation angle of the positioning frame is provided on the mounting base, the first rack, and the second rack.

[0006] As a preferred embodiment of this utility model, both the second rack and the first rack are arc-shaped, and the second rack and the first rack mesh with the adjacent gear to drive the positioning frame to rotate and adjust the angle.

[0007] As a preferred technical solution of this utility model, the fixing component includes a horizontally symmetrical clamping plate, which is slidably connected to the fixing base. A horizontally symmetrical guide rod is fixedly connected to the fixing base. The guide rod is slidably connected to the adjacent clamping plate, and an elastic element is connected between the guide rod and the adjacent clamping plate.

[0008] As a preferred technical solution of this utility model, the elastic element is specifically a spring.

[0009] As a preferred technical solution of this utility model, the reading component includes a finger rod, which is fixedly connected to the side of the first rack and the second rack near the positioning frame. A longitudinally symmetrical scale plate is fixedly connected to the mounting base, and the end of the finger rod away from the first rack and the second rack is slidably connected to the scale plate.

[0010] As a preferred technical solution of this utility model, the end of the scale plate near the finger rod is embedded in the mounting base, and the scale plate is flush with the upper side of the mounting base.

[0011] This utility model has the following advantages: 1. The LED light guide plate is placed in the corresponding left and right positioning frames. The positioning frames are used to position the LED light guide plate for splicing operations. When the splicing angle needs to be adjusted, the motor operation control gear cooperates with the first and second racks to drive the two corresponding left and right positioning frames to rotate together to adjust the angle. When the height needs to be adjusted, the electric push rod controls the lifting plate to slide upward. The upward sliding of the lifting plate drives the LED light guide plate to move upward for fine adjustment, so as to ensure the accuracy of splicing the two LED light guide plates. In this way, the splicing angle and height can be freely adjusted to meet different scene and shape requirements.

[0012] 2. After the clamping plate slides down and opens, the device can be moved to the operating table. Then, the clamping plate is released, and the elastic element resets to control the clamping plate to slide up and cooperate with the fixed seat to clamp the operating table, thereby fixing the fixed seat on the operating table.

[0013] 3. When the first and second racks rotate, the finger rod will also rotate. The angle of rotation of the positioning frame can be determined by observing the position of the finger rod pointing to the scale plate. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0023] Example 1: An LED light guide plate splicing device with positioning function, such as Figures 1-7 As shown, the assembly includes a fixed base 1, a mounting base 101, positioning frames 2, an LED light guide plate 3, a first rack 4, an adjusting motor 5, a second rack 6, a gear 7, a lifting support plate 8, an electric push rod 9, a fixing component, and a reading component. The mounting base 101 is fixedly connected to the upper side of the fixed base 1. Two positioning frames 2 are rotatably connected to the front and rear parts of the middle of the mounting base 101. An LED light guide plate 3 is placed inside the positioning frames 2. A first rack 4 is fixedly connected to the left positioning frame 2. An adjusting motor 5 is fixedly connected to the front and rear sides of the middle of the mounting base 101. A second rack 6 is fixedly connected to the right positioning frame 2. A gear 7 is fixedly connected to the output shaft of the adjusting motor 5. Both the second rack 6 and the first rack 4 are arc-shaped. The second rack 6 and the first rack 4 mesh with the adjacent gear 7 to drive the positioning frame 2 to rotate and adjust the angle. A lifting plate 8 is slidably connected inside the positioning frame 2. An electric push rod 9 is fixedly connected to the positioning frame 2. The telescopic end of the electric push rod 9 is fixedly connected to the adjacent lifting plate 8. A fixing component is provided on the fixing seat 1 to fix the fixing seat 1 in a designated position. The mounting seat 101, the first rack 4 and the second rack 6 are provided with a reading component for displaying the rotation angle of the positioning frame 2.

[0024] When using this device, the operator fixes it to the operating table using the fixing components. Then, the operator places the LED light guide plate 3 to be spliced ​​into the corresponding left and right positioning frames 2. At this time, the LED light guide plate 3 is supported by the lifting support plate 8. The positioning frames 2 position the LED light guide plate 3 for splicing. When the splicing angle needs to be adjusted, the operator drives the gear 7 to rotate through the adjusting motor 5. The rotation of the gear 7 drives the two corresponding left and right positioning frames 2 to rotate together through the first rack 4 and the second rack 6. The angle of rotation of the positioning frames 2 is displayed through the reading component. When the positioning frames 2 rotate to the appropriate angle, the operator controls the adjusting motor 5 to stop operating. When the height of the LED light guide plate 3 needs to be adjusted, the operator can control the lifting support plate 8 to slide upward through the electric push rod 9. The upward sliding of the lifting support plate 8 drives the LED light guide plate 3 to move upward for fine adjustment to ensure the accuracy of splicing the two LED light guide plates 3. After the LED light guide plate 3 is spliced, the operator controls the LED light guide plate 3 to move upward to remove it from the positioning frame 2. In this way, the splicing angle and height can be freely adjusted to meet different scene and shape requirements.

[0025] Example 2: Based on Example 1, such as Figure 1 and Figure 5 As shown, the fixing assembly includes a clamping plate 10, a guide rod 11, and an elastic element 12. The clamping plates 10 are slidably connected to both the left and right sides of the fixing base 1. The guide rods 11 are fixedly connected to both the left and right sides of the upper side of the fixing base 1. The guide rods 11 are slidably connected to the adjacent clamping plates 10. An elastic element 12 is connected between the guide rods 11 and the adjacent clamping plates 10. The elastic element 12 is specifically a spring.

[0026] When using the device, the operator controls the clamping plate 10 to slide downward on the guide rod 11. The elastic element 12 deforms and the clamping plate 10 slides downward to open. The operator can then move the device to the operating table, so that the fixed seat 1 is located on the upper side of the operating table and the clamping plate 10 is located on the lower side of the operating table. When the clamping plate 10 is released, under the action of the elastic element 12 resetting, the clamping plate 10 slides upward and cooperates with the fixed seat 1 to clamp the operating table, thereby fixing the fixed seat 1 on the operating table.

[0027] like Figure 1 , Figure 6 and Figure 7 As shown, the reading assembly includes a finger rod 13 and a scale plate 14. The first rack 4 and the second rack 6 are both fixedly connected to the finger rod 13 on the side near the positioning frame 2. The mounting base 101 is fixedly connected to the scale plate 14 symmetrically arranged in the middle. The end of the scale plate 14 near the finger rod 13 is embedded in the mounting base 101. The scale plate 14 is flush with the upper side of the mounting base 101. The end of the finger rod 13 away from the first rack 4 and the second rack 6 is slidably connected to the scale plate 14.

[0028] When using this device, as the first rack 4 and the second rack 6 drive the positioning frame 2 to rotate, the finger rod 13 will also rotate synchronously with the positioning frame 2. By observing the position of the finger rod 13 pointing to the scale plate 14, the operator can know the angle of rotation of the positioning frame 2, which makes it more convenient for the operator to adjust the operation.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
