[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0026] An aluminum substrate with positioning holes includes a substrate body 1. The substrate body 1 has a frame 101 on its exterior. The frame 101 has a plurality of positioning blocks 102. The positioning block 102 has a positioning hole 103 at its center. The positioning hole 103 is connected to an elastic block 104. The elastic block 104 has symmetrically arranged limiting blocks 105 inside. The frame 101 has symmetrically arranged first connecting blocks 2. When the positioning block 102 is inserted into the elastic block 104, the two limiting blocks 105 pass through the positioning hole 103 and limit the position of the positioning block 102.

[0027] The frame 101 is bonded to the substrate body 1 with epoxy adhesive, and two sets of positioning blocks 102 and elastic blocks 104 are respectively provided to facilitate the initial positioning when multiple aluminum substrates are spliced. The positioning hole 103 is adapted to the limiting block 105, and the elastic block 104 is U-shaped. The two limiting blocks 105 pass through the positioning hole 103 to initially limit the position of the aluminum substrates to be spliced.

[0028] In this embodiment, please refer to Figure 2 and Figure 3 and Figure 4The first connecting block 2 has a first groove 201 and a first protrusion 202. The frame 101 has a second connecting block 3 with symmetrically arranged second protrusions 301. The frame 101 has a third connecting block 4 with symmetrically arranged second grooves 401. The tops of the first groove 201 and the second groove 401 are respectively provided with threaded cylinders 5. The inside of the threaded cylinder 5 is provided with a threaded rod 501. One end of the threaded rod 501 is provided with a pressing block 502. The two sides of the pressing block 502 are symmetrically provided with sliders 503. The inside of the first protrusion 202 and the second protrusion 301 is provided with an upward-facing slot 6. The inner side wall of the slot 6 is provided with a limiting groove 601. The two side walls of the slot 6 are symmetrically provided with sliding grooves 602. The inside of the slot 6 is provided with a pressure plate 603. The bottom surface of the pressure plate 603 is provided with a compression spring 604. The threaded rod 501 is unthreaded. Part of it can slide freely up and down inside the threaded cylinder 5. Then, push the threaded rod 501 down. The pressing block 502 of the threaded rod 501 moves accordingly and drives the sliders 503 on both sides to slide down along the sliding groove 602 inside the first protrusion 202 or the second protrusion 301. When the slider 503 slides to the bottom of the sliding groove 602, the pressing block 502 will press the pressure plate 603 in the slot 6, so that the compression spring 604 is compressed. At this time, the threaded protrusion on the threaded rod 501 begins to make initial contact with the threaded cylinder 5. Next, rotate the threaded rod 501. Since the compression spring 604 has been compressed to the limit, the slider 503 will successfully enter the limiting groove 601 and rotate along the limiting groove 601 under the force generated by the rotation of the threaded rod 501, thereby forming a misalignment with the sliding groove 602. This misalignment makes the protrusion and the groove form a jamming state, realizing a firm splicing between the aluminum substrates.

[0029] The positioning block 102, elastic block 104, first connecting block 2, second connecting block 3, and third connecting block 4 are bonded to the frame 101 for easy replacement of damaged parts later. The first connecting block 2, second connecting block 3, and third connecting block 4 are all L-shaped and respectively located at the four corners of the frame 101, facilitating the splicing of multiple aluminum substrates. The threaded rod 501 has a threaded protrusion near its top, and the threaded rod 501 is compatible with the threaded cylinder 5. The slider 503 is compatible with the slide groove 602, and the slider 503 can slide up and down along the slide groove 602. 3 can slide along the limiting groove 601, and the limiting groove 601 is connected to the sliding groove 602. The downward displacement of the threaded rod 501 drives the slider 503 to slide down along the sliding groove 602 until the pressing block 502 presses the pressure plate 603, causing the compression spring 604 to be compressed. At this time, the threaded protrusion on the threaded rod 501 initially contacts the threaded cylinder 5. Then, the threaded rod 501 is rotated, and the compression spring 603 is compressed to its limit. The slider 503 can rotate along the limiting groove 601, causing it to be misaligned with the sliding groove 602. At this time, the protrusion and the groove are locked together, and the aluminum substrate splicing is completed.

[0030] The working process of this utility model is as follows: When using this type of aluminum substrate with positioning holes, firstly, during the splicing process of the aluminum substrate, the aluminum substrate to be spliced ​​is initially positioned by the positioning block 102 and the limiting block 105 on the elastic block 104. Then, the unthreaded part of the threaded rod 501 can slide freely up and down inside the threaded cylinder 5. Next, the threaded rod 501 is pushed down, and the pressing block 502 of the threaded rod 501 moves accordingly, driving the sliders 503 on both sides to slide down along the sliding groove 602 inside the first protrusion 202 or the second protrusion 301. When the slider 503 slides to the sliding groove 602, the sliding groove 602 is pushed down. When the groove 602 is at the bottom, the pressing block 502 will press the pressure plate 603 in the groove 6, causing the compression spring 604 to be compressed. At this time, the threaded protrusion on the threaded rod 501 will begin to make initial contact with the threaded cylinder 5. Next, the threaded rod 501 will be rotated. Since the compression spring 604 has been compressed to the limit, the slider 503 will successfully enter the limiting groove 601 and rotate along the limiting groove 601 under the force generated by the rotation of the threaded rod 501, thereby forming a misalignment with the slide groove 602. This misalignment makes the protrusion and the groove form a jamming state, realizing a firm splicing between the aluminum substrates.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
