Sheet metal part connecting and reinforcing structure

Abstract

This application relates to the technical field of sheet metal parts, and in particular to a sheet metal part connection and reinforcement structure, comprising a group of sheet metal parts, namely, Sheet Metal Part 1 and Sheet Metal Part 2, both of which have end blocks at their ends, with movable grooves on them. A locking element containing a locking segment and a pressing segment is slidably embedded in the movable groove. When Sheet Metal Part 1 and Sheet Metal Part 2 are tightened with bolts, the end blocks of both parts press down on the pressing segment of the locking element of the other, causing the locking segment to descend and fix the end of the sheet metal part, thus achieving connection reinforcement. This structure significantly improves the stability and reliability of the sheet metal part connection through the dual action of bolt tightening and locking element locking. Furthermore, it is simple in structure, easy to assemble, and suitable for various sheet metal assembly scenarios requiring high connection strength.

Description

Technical Field

[0001] This application relates to the technical field of sheet metal parts, and in particular to a sheet metal part connection and reinforcement structure. Background Technology

[0002] In the fields of mechanical manufacturing and structural assembly, sheet metal parts are widely used due to their light weight, high strength, and low manufacturing cost. Currently, the connection between sheet metal parts is mostly achieved by directly fastening bolts. However, under conditions of long-term vibration, uneven stress, or heavy load, this connection method is prone to problems such as bolt loosening and decreased connection strength, which in turn affects the stability and safety of the overall structure.

[0003] To address the aforementioned issues, existing technologies have employed solutions such as increasing the number of bolts or adding auxiliary positioning structures. However, increasing the number of bolts reduces assembly efficiency, and excessive bolt holes weaken the strength of the sheet metal part. Furthermore, ordinary auxiliary positioning structures often fail to synergize with bolt tightening, resulting in limited reinforcement and failing to meet the requirements for high-precision and high-stability connections. Therefore, to solve these problems, this application provides a sheet metal part connection reinforcement structure. Utility Model Content

[0004] To address the aforementioned issues, this application provides a sheet metal connection reinforcement structure.

[0005] This application provides a sheet metal connection reinforcement structure, characterized in that it includes a group of sheet metal parts one and two; each of the end faces of sheet metal parts one and two is provided with an end block, and each of the sheet metal parts one and two is provided with a movable groove; a locking member is slidably embedded inside the movable groove, the locking member including a locking section and a pressing section; when sheet metal parts one and two cooperate with each other and are locked by bolts passing through bolt holes, the end blocks of both are pressed on the pressing section of the locking member slidably embedded inside the other, thereby causing the locking section to move downwards and fixing the end of the sheet metal part, thus achieving the reinforcement effect of the connection between sheet metal parts one and two.

[0006] Preferably, the structures of sheet metal part one and sheet metal part two are symmetrically arranged.

[0007] Preferably, the shape of the movable groove is adapted to the sliding trajectory of the locking member to ensure that the locking member can slide smoothly within the movable groove.

[0008] Preferably, the end block is positioned to correspond to the position of the pressing section, so as to ensure that the end block can be accurately pressed onto the pressing section when the bolt is tightened.

[0009] Preferably, after the locking segment descends, it engages with the structure at the end of the sheet metal part, thereby fixing the end of the sheet metal part.

[0010] Preferably, the bolt and bolt hole are fitted with an interference fit to ensure the stability of the connection.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] By incorporating mating end blocks and locking mechanisms on sheet metal parts, the locking mechanism simultaneously triggers its locking action during the initial bolt tightening process between sheet metal parts one and two, forming a dual-fixing structure of "bolt tightening + locking reinforcement." This design not only utilizes bolts for basic connection but also effectively resists vibration and loosening tendencies at the connection points through the mechanical locking of the sheet metal parts' ends by the locking mechanism, significantly improving the overall connection strength and stability. Furthermore, this reinforcement process is completed simultaneously with bolt tightening, requiring no additional steps. While ensuring reinforcement effectiveness, it also considers assembly efficiency, solving the problems of easy loosening and limited reinforcement effect in traditional single-bolt connections.

[0018] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0019] Example 1:

[0020] A sheet metal connection reinforcement structure, referring to Figure 1 - Figure 4 A sheet metal connection and reinforcement structure, as shown in the figure, includes a group of sheet metal parts 1 and 2, which are designed to fit together to achieve a tight connection. Both sheet metal parts 1 and 2 have integrally formed end blocks 5 on their end faces. The end blocks 5 are rectangular blocks and are perpendicular to the sheet metal parts.

[0021] Movable grooves 12 are provided on the end sides of both sheet metal parts 1 and 2. The movable grooves 12 extend along the length of the sheet metal parts and have a "T" shaped cross-section. A locking member 4 is slidably embedded inside the movable groove 12 and can slide freely along the length of the movable groove 12. The locking member 4 includes an integrally formed latching section 41 and a pressing section 42. The latching section 41 is located inside the movable groove 12 and has a hook-shaped structure. The pressing section 42 is located outside the movable groove 12 and has a flat plate-shaped structure, with its end slightly higher than the end face of the sheet metal parts.

[0022] Sheet metal part 1 and sheet metal part 2 are provided with corresponding bolt holes 11, two in total, symmetrically distributed on both sides of the movable groove 12. After the bolt 3 passes through the bolt hole 11, sheet metal part 1 and sheet metal part 2 can be fastened together.

[0023] When it is necessary to connect and fix sheet metal part 1 and sheet metal part 2, first align the ends of the two, so that the end block 5 of sheet metal part 1 corresponds to the pressing section 42 of the locking member 4 of sheet metal part 2, and at the same time, the end block 5 of sheet metal part 2 corresponds to the pressing section 42 of the locking member 4 of sheet metal part 1. Then, pass the bolt 3 through the bolt hole 11 and gradually tighten it. During this process, as the bolt 3 is tightened, the end blocks 5 of sheet metal part 1 and sheet metal part 2 will gradually move closer and press on the pressing section 42 of the locking member 4 of the other.

[0024] When the pressing section 42 is subjected to pressure, it will drive the entire locking component 4 downward along the movable groove 12. At this time, the locking section 41 will move downward simultaneously and engage with the end edge of the other sheet metal part, thereby forming a double fixation for the ends of the two sheet metal parts. Through this structural design, not only is the initial fixation achieved by the bolt 3, but the locking action of the locking component 4 also achieves secondary reinforcement, effectively improving the stability and reliability of the connection between the two sheet metal parts.

[0025] In this embodiment, sheet metal part 1 and sheet metal part 2 adopt a symmetrical structural design and are interchangeable, reducing production and assembly costs. The inner wall of the movable groove 12 is smoothed, and its size is adapted to the size of the locking part 4, ensuring the smooth sliding of the locking part 4. The end of the locking section 41 is provided with anti-slip teeth, which can enhance its engagement effect with the end of the sheet metal part. The bolt 3 and the bolt hole 11 adopt an interference fit, further ensuring the stability of the connection.

[0026] The foregoing description, with reference to preferred embodiments, illustrates an exemplary implementation of a sheet metal connection reinforcement structure provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
