Description

Technical Field

[0001] This utility model relates to the field of precision sheet metal processing technology, specifically to a modular splicing structure for precision sheet metal boxes. Background Technology

[0002] Existing precision sheet metal enclosures mostly adopt integral welding or integrated bolt-fixed structures, which have problems such as high transportation costs, fixed overall enclosure volume that cannot be disassembled, resulting in low packaging space utilization and significantly increased logistics costs during long-distance transportation; as well as high maintenance difficulty, when a part of the enclosure is damaged, the entire structure must be disassembled for replacement, which is complicated and can easily damage other precision components; and poor adaptability, as new enclosures must be designed and manufactured to meet the installation requirements of different equipment, and the size or function cannot be flexibly adjusted using existing modules, resulting in long production cycles and high costs.

[0003] Therefore, there is an urgent need for a modular splicing structure that is detachable, easy to assemble, and has high precision to solve the defects of the aforementioned integral sheet metal box. Utility Model Content

[0004] The purpose of this utility model is to provide a modular splicing structure for precision sheet metal boxes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision sheet metal box modular splicing structure, including independent sheet metal modules and connecting components, wherein the left end of the independent sheet metal module is provided with a splicing insertion end, and the right end of the independent sheet metal module is provided with a splicing outer end, wherein the splicing insertion end and the splicing outer end are integrally formed with the independent sheet metal module, and the outer diameter of the splicing insertion end matches the inner diameter of the splicing outer end; The connecting component includes an arc-shaped groove and a mounting groove. The arc-shaped groove is formed on the outer wall of the splicing insertion end, and the mounting groove is formed on the inner wall of the splicing outer end. The four outer walls of the splicing insertion end are each provided with an arc-shaped groove, and the four inner walls of the splicing outer end are each provided with a mounting groove. An arc-shaped elastic plate is snapped into the mounting groove. The middle section of the arc-shaped elastic plate extends out of the mounting groove and matches the arc-shaped groove. The front and back of the splicing outer end are provided with secondary fixing components, which fix the connecting component.

[0006] Furthermore, the secondary fixing component includes a hidden groove, which is formed on the front and back of the splicing outer sleeve end. A mounting plate is connected to the hidden groove by screws. A through hole is formed on the inner wall of the hidden groove facing the inside of the splicing outer sleeve end. The through hole communicates with the inside of the mounting groove. A top rod is fixedly installed on the outer wall of the mounting plate facing the mounting groove. The top rod extends into the mounting groove from the through hole and rests on the center of the arc-shaped elastic plate.

[0007] Furthermore, the thickness of the mounting plate is consistent with the depth of the hidden groove, and the screws connecting the hidden groove and the mounting plate are countersunk screws.

[0008] Furthermore, the left and right ends of the arc-shaped elastic plate are inserted into the mounting groove, and the lower surface of the arc-shaped elastic plate is polished.

[0009] Furthermore, a reinforcing support frame is fixedly fitted on the outer wall of the independent sheet metal module. The reinforcing support frame is close to the splicing insertion end on the independent sheet metal module, and the upper and lower surfaces of the reinforcing support frame are flush with the upper and lower surfaces of the splicing outer end.

[0010] Furthermore, a rectangular groove two is provided at the end face of the splicing outer sleeve end, and a rectangular groove one is provided at the end face of the connection between the splicing outer sleeve end and the independent sheet metal module. A sealing strip is installed in the rectangular groove one, and the inner diameters of the rectangular groove one and the rectangular groove two are the same.

[0011] Furthermore, the independent sheet metal module has slots inside, and there are three slots in one independent sheet metal module, with partitions engaged in the slots.

[0012] Furthermore, mounting holes 2 are provided on both the upper and lower surfaces of the reinforced support frame, and mounting holes 1 are provided on both the upper and lower surfaces of the splicing outer sleeve end.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Adjacent independent sheet metal modules are spliced ​​by plugging in, which is faster. Because the splicing insertion end is inserted into the splicing outer end, the splicing outer end can provide sufficient support and restraint at the connection point. 2. When the splicing insert end is inserted into the splicing outer sleeve end, the arc-shaped elastic plate is pushed by the end of the splicing insert end, causing the arc-shaped elastic plate to deform and enter the mounting groove. After the splicing insert end is inserted into place, the middle section of the arc-shaped elastic plate aligns with the arc-shaped groove. At this time, the elasticity of the arc-shaped elastic plate itself pushes the middle section of the arc-shaped elastic plate into the arc-shaped groove, thereby realizing the snap-fit ​​connection between the splicing insert end and the splicing outer sleeve end. This connection method is quick and convenient. A secondary fixing component is set to fix the connecting component to ensure the stability of the connection. 3. After the arc-shaped elastic plate is inserted into the arc-shaped groove, the top rod presses against the middle section of the arc-shaped elastic plate, so that the arc-shaped elastic plate will not deform again and detach from the arc-shaped groove, thereby ensuring the stability of the connection between the arc-shaped elastic plate and the arc-shaped groove.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1-10This utility model provides a technical solution: a precision sheet metal box modular splicing structure, including an independent sheet metal module 1 and a connecting component 4. The left end of the independent sheet metal module 1 is provided with a splicing insertion end 101, and the right end of the independent sheet metal module 1 is provided with a splicing outer end 102. Both the splicing insertion end 101 and the splicing outer end 102 are integrally formed with the independent sheet metal module 1. The outer diameter of the splicing insertion end 101 matches the inner diameter of the splicing outer end 102. Adjacent independent sheet metal modules 1 are spliced ​​by insertion, which is faster. And because the splicing insertion end 101 is inserted into the splicing outer end 102, the splicing outer end 102 can provide sufficient support and limit at the connection. The connecting component 4 includes an arc-shaped groove 401 and a mounting groove 402. The arc-shaped groove 401 is formed on the outer wall of the splicing insertion end 101, and the mounting groove 402 is formed on the inner wall of the splicing outer end 102. Arc-shaped grooves 401 are provided on the outer walls of all four sides of the splicing insertion end 101, and mounting grooves 402 are provided on the inner walls of all four sides of the splicing outer end 102. An arc-shaped elastic plate 403 is snapped into the mounting groove 402. The middle section of the arc-shaped elastic plate 403 extends from the mounting groove 402 and matches the arc-shaped groove 401. Secondary fixing components 8 are provided on both the front and back of the splicing outer end 102. The secondary fixing components 8 are connected to the connecting component. 4. Fixing: When the splicing insertion end 101 is inserted into the splicing outer end 102, the arc-shaped elastic plate 403 is pushed by the end of the splicing insertion end 101, causing the arc-shaped elastic plate 403 to deform and enter the mounting groove 402. After the splicing insertion end 101 is inserted into place, the middle section of the arc-shaped elastic plate 403 is aligned with the arc-shaped groove 401. At this time, the elasticity of the arc-shaped elastic plate 403 itself pushes the middle section of the arc-shaped elastic plate 403 into the arc-shaped groove 401, thereby realizing the snap-fit ​​connection between the splicing insertion end 101 and the splicing outer end 102. This connection method is quick and convenient. A secondary fixing component 8 is set to fix the connecting component 4 to ensure the stability of the connection. The secondary fixing component 8 includes a hidden groove 801, which is formed on the front and back of the splicing outer sleeve end 102. A mounting plate 802 is connected to the hidden groove 801 by screws. A through hole 804 is formed on the inner wall of the hidden groove 801 facing the inside of the splicing outer sleeve end 102. The through hole 804 communicates with the inside of the mounting groove 402. A top rod 803 is fixedly installed on the outer wall of the mounting plate 802 facing the mounting groove 402. The top rod 803 extends into the mounting groove 402 from the through hole 804. The top rod 803 is pressed against the center of the arc-shaped elastic plate 403. After the arc-shaped elastic plate 403 is inserted into the arc-shaped groove 401, the top rod 803 presses against the middle section of the arc-shaped elastic plate 403, so that the arc-shaped elastic plate 403 will not deform again and detach from the arc-shaped groove 401, thereby ensuring the stability of the connection between the arc-shaped elastic plate 403 and the arc-shaped groove 401. The thickness of the mounting plate 802 is the same as the depth of the hidden groove 801. The screws connecting the hidden groove 801 and the mounting plate 802 are countersunk screws, so that the mounting plate 802 will not protrude from the hidden groove 801, and the screws connecting the hidden groove 801 and the mounting plate 802 will not protrude from the hidden groove 801. The left and right ends of the arc-shaped elastic plate 403 are inserted into the mounting groove 402. The lower surface of the arc-shaped elastic plate 403 is polished so that when the arc-shaped elastic plate 403 is subjected to force, it can deform and enter into the mounting groove 402. Because the surface of the arc-shaped elastic plate 403 is rounded, the friction force on the splicing insertion end 101 when it abuts against the surface of the arc-shaped elastic plate 403 can be reduced, thereby reducing the resistance encountered when inserting the splicing insertion end 101. The outer wall of the independent sheet metal module 1 is fixedly fitted with a reinforcing support frame 9. The reinforcing support frame 9 is close to the splicing insertion end 101 on the independent sheet metal module 1. The upper and lower surfaces of the reinforcing support frame 9 are flush with the upper and lower surfaces of the splicing outer end 102. The reinforcing support frame 9 is set to reinforce the independent sheet metal module 1. At the same time, it is flush with the splicing outer end 102, so that the independent sheet metal module 1 can be placed stably on the plane. A rectangular groove 2 7 is provided at the end face of the splicing outer end 102, and a rectangular groove 1 6 is provided at the end face where the splicing outer end 102 connects with the independent sheet metal module 1. A sealing strip 5 is installed in the rectangular groove 1 6. The inner diameters of the rectangular groove 1 6 and the rectangular groove 2 7 are the same. The rectangular groove 1 6 is set to install the sealing strip 5. When connecting the splicing insertion end 101 and the splicing outer end 102, the sealing strip 5 can be inserted into the rectangular groove 2 7 to ensure the sealing of the box after splicing and prevent dust and moisture from entering. The independent sheet metal module 1 has a slot 2 inside, and there are three slots 2 in one independent sheet metal module 1. A partition 3 is snapped into the slot 2 for internal layering of the box. Mounting holes 2 11 are provided on the upper and lower surfaces of the reinforcing support frame 9, and mounting holes 10 are provided on the upper and lower surfaces of the splicing outer sleeve end 102. The mounting holes 10 and 2 11 are provided so that when it is necessary to fix the box, the placement platform can be connected to the mounting holes 10 and 2 11 using bolts or other fasteners.

[0018] Working principle: In use, align the splicing insertion end 101 with the splicing outer end 102 and insert it. After insertion, align the middle section of the arc-shaped elastic plate 403 with the arc-shaped groove 401 and snap it in. The splicing insertion end 101 and the splicing outer end 102 are snapped together. Align the top rod 803 with the through hole 804 and insert it. Then press the mounting plate 802 into the hidden groove 801 and use screws to fix the mounting plate 802. The top rod 803 presses against the middle section of the arc-shaped elastic plate 403, which can prevent the arc-shaped elastic plate 403 from coming out of the arc-shaped groove 401 and ensure the splicing strength of the box.

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
