Description

Technical Field

[0001] This utility model relates to the field of sheet metal splicing structure technology, specifically a quick-connect mechanical sheet metal splicing structure. Background Technology

[0002] Sheet metal parts refer to various metal components made from sheet metal through processes such as cutting, bending, stamping, and welding. They are widely used in machinery manufacturing, electronic equipment, automotive industry, construction, and other fields. Sheet metal parts typically have advantages such as being lightweight, high-strength, and easy to process. Currently, sheet metal parts are usually fixed by welding or bolting during assembly. Welding requires the use of welding equipment for hot-melt splicing; while welding provides good connection strength, the process is complex and requires specialized skills. Bolting, on the other hand, requires the use of wrenches and other tools to tighten bolts. Although the operation is relatively simple, it still incurs time and labor costs during assembly. Both of these splicing and fixing methods can lead to reduced overall assembly efficiency, especially in situations requiring frequent disassembly and maintenance.

[0003] Utility model patent CN221033498U discloses a splicing precision sheet metal part, including a first sheet metal part and a second sheet metal part. One end of the first sheet metal part has a connecting groove, and one end of the second sheet metal part has a connecting block. A slot is formed on one side of the connecting block. A limiting mechanism is provided inside the first sheet metal part, a control rod is provided on one side of the first sheet metal part, and a moving groove is formed on one side of the first sheet metal part. This utility model, by setting up the connecting groove, connecting block, slot, limiting mechanism, control rod, and moving groove, provides a splicing and fixing structure that does not require external auxiliary equipment or tools, making it more convenient and further improving the ease of fixing precision sheet metal parts during splicing. Furthermore, after the first and second sheet metal parts are spliced ​​and fixed, the splicing and fixing structure is less prone to loosening as the first and second sheet metal parts are used over time, further improving the stability of the precision sheet metal part splicing and fixing.

[0004] While the existing technology can achieve the splicing of two adjacent sheet metal parts, its splicing and fixing structure has obvious defects. First, during splicing, the operator needs to press two control levers simultaneously to retract the two fixing blocks into their respective slots, resulting in a slow splicing process and affecting work efficiency. Second, due to the movable slots in the design, external impurities can easily enter the slots. Over time, these impurities may accumulate in the space between the first and second magnet blocks, making it difficult for the fixing blocks to retract smoothly into the slots when the sheet metal parts need to be disassembled, ultimately preventing the two sheet metal parts from being effectively separated. To address these issues, we propose a quick-connect mechanical sheet metal splicing structure to improve splicing efficiency while enhancing the stability and ease of connection. Utility Model Content

[0005] The purpose of this invention is to provide a quick-connect mechanical sheet metal splicing structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A quick-connect mechanical sheet metal splicing structure includes sheet metal parts. Adjacent sheet metal parts are physically connected via splicing blocks and splicing slots. Splicing blocks are located on the left side of each sheet metal part, near both the top and bottom ends. The splicing blocks are initially positioned by inserting into the splicing slots of adjacent sheet metal parts. A first guide bevel is formed on the left end of the opposite sides of each of the two splicing blocks. A splicing slot, adapted to the splicing blocks, is formed on the right side of each sheet metal part, near both the top and bottom ends. A rectangular through-slot is formed between the two splicing slots, providing installation and movement space for a positioning component. A positioning component is installed within the rectangular through-slot. The positioning component controls the extension and retraction of the positioning blocks via gear and rack linkage, enabling quick locking or unlocking.

[0008] The positioning component includes a gear rotatably connected to the rear center of the inner wall of the rectangular through groove. The gear serves as the transmission core, driving the racks on both sides to move in opposite directions via a knob. The positioning component also includes two racks that mesh with the gear, converting rotational motion into linear motion to drive the slider to move. A slider is provided at the top of the left rack and at the bottom of the right rack. Positioning blocks are provided on the opposite sides of the two sliders. Positioning holes for the positioning blocks to be inserted are provided in the center of the opposite sides of the two splicing blocks. The positioning blocks lock the splicing blocks by inserting them into the positioning holes, ensuring connection stability. A second guide bevel is provided at the right end of the opposite sides of the two positioning blocks. The first and second guide bevels cooperate, allowing the positioning blocks to retract into the rectangular through groove when subjected to force, thus enabling the splicing blocks to be smoothly inserted into the splicing groove, which is beneficial for the rapid splicing of sheet metal parts.

[0009] Preferably, the positioning component further includes a knob rotatably connected to the front side of the sheet metal part. The rotating shaft of the knob is coaxially connected to the rotating shaft of the gear. Rotating the knob can drive the gear to rotate, thereby causing the gear to move the left rack down and the right rack up, which in turn causes the two positioning blocks to retract into the rectangular through slot, thereby achieving the unlocking function and facilitating disassembly.

[0010] Preferably, both racks mesh with gears for transmission, and the opposite sides of the two racks are respectively attached to the left and right sides of the inner wall of the rectangular through groove. The attachment design limits the movement trajectory of the racks and avoids deflection.

[0011] Preferably, the outer side of the slider is in contact with the inner wall of the rectangular through groove. This contact structure enhances the stability of the slider's movement and prevents it from shaking.

[0012] Preferably, the rear side of the inner wall of the rectangular through groove is provided with two fixed support blocks arranged symmetrically in the upper and lower positions, and the gear is located between the two fixed support blocks.

[0013] Preferably, each of the two sliders is provided with a spring on its opposite side, with the end of the spring away from the slider abutting against the side of the fixed support block. The spring provides the positioning block with a reset force, ensuring that it automatically returns to its original position after unlocking.

[0014] Preferably, when two adjacent sheet metal parts are spliced, the splicing block of the right sheet metal part is inserted into the splicing groove of the left sheet metal part, and the adjacent sheet metal parts are physically connected through the insertion of the splicing block and the splicing groove. The positioning block of the positioning component on the left is inserted into the positioning hole of the right splicing block, and the insertion of the positioning block and the positioning hole forms a mechanical lock to prevent loosening after splicing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This quick-connect mechanical sheet metal splicing structure, through the guiding cooperation between the splicing blocks and the splicing grooves, combined with the insertion and locking structure of the positioning blocks and the positioning holes, allows for initial alignment during splicing simply by pushing the sheet metal parts. The positioning blocks are automatically guided by the guide beveled surface to retract, eliminating the need to press multiple parts or use tools. During disassembly, rotating a single knob simultaneously controls the retraction of the positioning blocks on both sides, greatly simplifying the operation process and making it particularly suitable for scenarios involving frequent disassembly and assembly.

[0017] 2. The quick-connect mechanical sheet metal splicing structure, the gear-rack transmission system in the positioning component ensures that the positioning blocks on both sides extend and retract synchronously, and combined with the elastic reset function of the spring, the positioning blocks remain stable after being inserted into the positioning holes; the rigid insertion of the splicing block and the splicing groove, together with the mechanical locking of the positioning block, forms a fixing mechanism.

[0024] Please see Figs. 1-3 This utility model provides a technical solution:

[0025] A quick-connect mechanical sheet metal splicing structure includes sheet metal parts 100. Adjacent sheet metal parts are physically connected via splicing blocks 200 and splicing grooves 101. Splicing blocks 200 are located on the left side of the sheet metal parts 100, near the top and bottom ends. The splicing blocks 200 are initially positioned by inserting into the splicing grooves 101 of adjacent sheet metal parts 100. A first guide bevel 201 is provided on the left end of the opposite sides of the two splicing blocks 200. Splicing grooves 101, adapted to the splicing blocks 200, are provided on the right side of the sheet metal parts 100, near the top and bottom ends. A rectangular through-slot 102 is provided between the two splicing grooves 101, providing installation and movement space for a positioning component 300. The positioning component 300 is located within the rectangular through-slot 102. The positioning component 300 controls the extension and retraction of the positioning block 340 via a gear 310 and a rack 320, enabling quick locking or unlocking.

[0026] The positioning assembly 300 includes a gear 310 rotatably connected to the middle of the rear side of the inner wall of the rectangular through groove 102. The gear 310 serves as the transmission core, driving the racks 320 on both sides to move in opposite directions via a knob 360. The positioning assembly 300 also includes two racks 320 that mesh with the gear 310, converting rotational motion into linear motion to drive the slider 330 to move. A slider 330 is located at the top of the left rack 320 and at the bottom of the right rack 320. Positioning blocks 340 are provided on the opposite sides of both sliders 330. Each of the splicing blocks 200 has a positioning hole 202 in the middle of its opposite side for the positioning block 340 to insert into. The positioning block 340 locks the splicing block 200 by inserting into the positioning hole 202 to ensure connection stability. The right end of the opposite side of each of the two positioning blocks 340 has a second guide bevel surface 341. The first guide bevel surface 201 and the second guide bevel surface 341 cooperate, and the positioning block 340 can retract into the rectangular through groove 102 when subjected to force, so that the splicing block 200 can be smoothly inserted into the splicing groove 101, which is conducive to the rapid splicing of the sheet metal parts 100.

[0027] In this embodiment, the positioning component 300 also includes a knob 360 rotatably connected to the front side of the sheet metal part 100. The rotating shaft of the knob 360 is coaxially connected to the rotating shaft of the gear 310. Rotating the knob 360 can drive the gear 310 to rotate, thereby causing the gear 310 to drive the left rack 320 to move down and the right rack 320 to move up, thereby causing the two positioning blocks 340 to retract into the rectangular through groove 102, achieving the unlocking function and facilitating disassembly.

[0028] Specifically, both racks 320 mesh with gears 310 for transmission. The opposite sides of the two racks 320 are respectively attached to the left and right sides of the inner wall of the rectangular through groove 102. The attachment design limits the movement trajectory of the racks 320 and avoids deflection.

[0029] Furthermore, the outer side of the slider 330 is in contact with the inner wall of the rectangular through groove 102. This contact structure enhances the stability of the slider 330's movement and prevents it from wobbling.

[0030] Furthermore, two fixed support blocks 103 are provided on the rear side of the inner wall of the rectangular through groove 102, which are arranged symmetrically in the upper and lower positions, and the gear 310 is located between the two fixed support blocks 103.

[0031] Furthermore, springs 350 are provided on the opposite sides of the two sliders 330. The end of the spring 350 away from the slider 330 abuts against the side of the fixed support block 103. The spring 350 provides the reset force of the positioning block 340 to ensure that it automatically returns to its original position after unlocking.

[0032] Furthermore, when two adjacent sheet metal parts 100 are spliced, the splicing block 200 of the right sheet metal part 100 is inserted into the splicing groove 101 of the left sheet metal part 100. The adjacent sheet metal parts 100 are physically connected through the splicing block 200 and the splicing groove 101. The positioning block 340 of the left positioning component 300 is inserted into the positioning hole 202 of the right splicing block 200. The insertion of the positioning block 340 and the positioning hole 202 forms a mechanical lock to prevent loosening after splicing.

[0033] In this embodiment, the quick-connect mechanical sheet metal splicing structure is used by first aligning the splicing block 200 of sheet metal part 100 with the splicing groove 101 of another sheet metal part 100, and then pushing the sheet metal part 100 to insert the splicing block 200 into the splicing groove 101. During this process, the first guide bevel surface 201 on the splicing block 200 contacts the second guide bevel surface 341 of the positioning block 340, pushing the positioning block 340 to retract into the rectangular through groove 102, while the spring 350 is compressed and stores energy. When the splicing block 200 is fully inserted into the splicing groove 101, the positioning hole 202 aligns with the positioning block 340, and the spring 350 releases its elastic force to push the slider 3. 30 and positioning block 340 move outward and insert into positioning hole 202 to complete mechanical locking; at this time, gear 310 and rack 320 remain engaged and stationary to ensure stable engagement of positioning block 340; when disassembly is required, rotate knob 360 to drive gear 310 to rotate, gear 310 drives left rack 320 to move down and right rack 320 to move up, rack 320 drives positioning block 340 to retract into rectangular through groove 102 and disengage from positioning hole 202 through slider 330; at this time, splicing block 200 and splicing groove 101 are unlocked, and sheet metal part 100 can be separated by pulling in the opposite direction. The whole process does not require additional tools and is simple and efficient to operate.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
