Description

Technical Field

[0001] This utility model relates to the field of sheet metal connection technology, and in particular to a high-strength sheet metal connection structure. Background Technology

[0002] Sheet metal parts are a comprehensive cold working process for thin metal sheets, including shearing, punching, bending, welding, splicing, and forming. Its significant characteristic is that the thickness of the same part is consistent. Products processed by sheet metal technology are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used as a term when assembling parts.

[0003] Traditional sheet metal parts are often made of a single thin plate, which often has low rigidity. High-strength sheet metal parts are characterized by high strength and toughness. In the current technology, the connection points of traditional sheet metal parts are often connected by welding or bolts. Welding will make the sheet metal parts unable to be disassembled as a whole. If damage occurs later, the whole part needs to be replaced, which will increase the cost of use to a certain extent and make it impractical. Therefore, it is necessary to design a high-strength sheet metal connection structure to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a high-strength sheet metal connection structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-strength sheet metal connection structure includes a first sheet metal part and a second sheet metal part. Two connecting sleeves are fixedly installed on the inner walls of both the first and second sheet metal parts. Connecting blocks are slidably installed inside the two opposing connecting sleeves. A fixing bolt is rotatably installed through a connecting hole on the outer wall of each connecting sleeve. Threaded holes for the fixing bolts are opened on the outer walls of both connecting blocks. A fixing block is slidably installed on the outer walls of both connecting blocks through connecting grooves. Two sliding rods are fixedly installed on the outer walls of the fixing blocks through moving grooves. Two moving plates are slidably installed on the outer walls of the two sliding rods through a limiting mechanism. A pin is fixedly installed on the outer wall of each moving plate. Insertion holes for the pins are opened on both sides of the outer walls of the two connecting blocks. Two extrusion bolts are rotatably installed on the outer walls of the fixing blocks through a support mechanism. Extrusion plates are rotatably connected to the ends of the two extrusion bolts through a connecting mechanism.

[0007] Preferably, the limiting mechanism includes a limiting rod fixedly installed inside the moving groove, the limiting rod sliding through the moving plate.

[0008] Preferably, the support mechanism includes a support plate fixedly installed on the outer wall of the fixed block, and the screw thread of the extrusion bolt rotates through the support plate.

[0009] Preferably, the connecting mechanism includes a connecting block fixedly installed at the end of the extrusion bolt, the end of which is rotatably connected to the outer wall of the extrusion plate.

[0010] Preferably, the outer wall of the fixing block has two mounting grooves, and the outer wall of the fixing block is slidably fitted with baffles that cooperate with the two moving grooves.

[0011] Preferably, magnetic blocks are fixedly installed inside both mounting slots and on the inner walls of both baffles, with the magnetic poles of the two opposing magnetic blocks being opposite.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting components such as slide rod, movable plate, spring and pin, when the fixed block is slidably installed inside the two connecting slots, the spring can pull the corresponding movable plate to slide on the outer wall of the slide rod through the cooperation of the limit rod, and drive the pin to move into the corresponding insertion hole. This can realize the installation and fixation of the fixed block inside the connecting slot, thereby realizing the fixed connection between the first sheet metal part and the second sheet metal part.

[0014] 2. By setting up components such as extrusion bolts, connecting blocks and pressure plates, the extrusion bolts are turned to rotate. At this time, the extrusion bolts can drive the extrusion plate to move through the connecting blocks. As the extrusion bolts continue to rotate, the extrusion plate can be driven to contact and extrude with the first sheet metal part and the second sheet metal part, thereby increasing the reliability of the connection between the first sheet metal part and the second sheet metal part.

Detailed Implementation

[0021] 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.

[0022] Reference Figure 1-5 The high-strength sheet metal connection structure includes a first sheet metal part 1 and a second sheet metal part 2. Two connecting sleeves 3 are fixedly installed on the inner walls of both the first sheet metal part 1 and the second sheet metal part 2. Connecting blocks 4 are slidably installed inside the two opposing connecting sleeves 3. A fixing bolt 5 is rotatably installed through the connecting hole on the outer wall of each connecting sleeve 3. Threaded holes for the fixing bolt 5 are opened on the outer walls of the two connecting blocks 4. Fixing blocks 6 are slidably installed on the outer walls of the two connecting blocks 4 through the connecting groove. Two sliding rods 7 are fixedly installed on the outer walls of the fixing blocks 6 through the moving groove.

[0023] Two sliding plates 10 are slidably installed on the outer walls of the two sliding rods 7 via a limiting mechanism. The limiting mechanism includes a limiting rod 8 fixedly installed inside the moving groove. The limiting rod 8 slides through the moving plate 10. A pin 11 is fixedly installed on the outer wall of each moving plate 10. Insert holes that cooperate with the pins 11 are opened on the outer walls of both sides of the two connecting blocks 4. Two mounting grooves are opened on the outer wall of the fixing block 6. A baffle 12 that cooperates with the two moving grooves is slidably installed on the outer wall of the fixing block 6. Magnetic blocks 13 are fixedly installed inside the two mounting grooves and on the inner walls of the two baffles 12. The magnetic poles of the two opposing magnetic blocks 13 are opposite.

[0024] Two compression bolts 15 are rotatably installed on the outer wall of the fixed block 6 via a support mechanism. The support mechanism includes a support plate 14 fixedly installed on the outer wall of the fixed block 6. The compression bolts 15 are threaded through the support plate 14. The ends of the two compression bolts 15 are rotatably connected to compression plates 17 via a connecting mechanism. The connecting mechanism includes a connecting block 16 fixedly installed on the ends of the compression bolts 15. The ends of the connecting block 16 are rotatably connected to the outer wall of the compression plate 17.

[0025] When using this utility model, the two connecting blocks 4 are inserted into the connecting sleeves 3 on both sides respectively, and the threaded holes are aligned with the fixing bolts 5. Then, the fixing bolts 5 can be screwed in to make them penetrate into the threaded holes. This allows the connecting blocks 4 to be installed and fixed inside the connecting sleeves 3. When connecting the first sheet metal part 1 and the second sheet metal part 2, the fixing block 6 can be slidably installed inside the two connecting grooves. Then, the spring 9 can pull the corresponding moving plate 10, so that the moving plate 10 slides on the outer wall of the slide rod 7 through the cooperation of the limiting rod 8, and drives the pin 11 to move into the corresponding insertion hole. This allows the fixing block 6 to be installed and fixed inside the connecting groove, thereby achieving a fixed connection between the first sheet metal part 1 and the second sheet metal part 2.

[0026] After the first sheet metal part 1 and the second sheet metal part 2 are connected, the pressing bolt 15 can be turned. At this time, the pressing bolt 15 can drive the pressing plate 17 to move through the connecting block 16. As the pressing bolt 15 continues to rotate, the pressing plate 17 can contact and press with the first sheet metal part 1 and the second sheet metal part 2, thereby increasing the reliability of the connection between the first sheet metal part 1 and the second sheet metal part 2. Then, the baffle 12 can be attracted to the outer wall of the fixing block 6 by the magnetic attraction block 13 with opposite magnetic poles. This allows the baffle 12 to shield and protect the components inside the moving groove. When it is necessary to contact the connection between the first sheet metal part 1 and the second sheet metal part 2, the baffle 12 can be removed first. Then, the two moving plates 10 on the same side can be pinched. At this time, the two moving plates 10 on the same side can respectively drive the corresponding pins 11 to move out of the insertion hole, thereby releasing the fixing block 6 inside the connecting groove. Then, the fixing block 6 can be removed from the two connecting grooves, thereby releasing the connection between the first sheet metal part 1 and the second sheet metal part 2.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
