Description

Technical Field

[0001] This utility model relates to the field of sheet metal parts technology, and in particular to a sheet metal part with adaptive assembly tolerance. Background Technology

[0002] Sheet metalworking is a comprehensive cold working process for thin metal sheets (usually less than 6mm), characterized by a consistent thickness for the same part. Products manufactured using sheet metalworking are called sheet metal parts. The term "sheet metal part" generally varies across different industries, but is often used in assembly contexts. Sheet metal parts are characterized by their light weight, high strength, electrical conductivity, low cost, and good mass production capabilities, and are widely used in electronics, communications, automotive, and medical device industries.

[0003] Chinese patent application CN202222641955.8 discloses a sheet metal part with adaptive assembly tolerance, comprising one or more bodies, with adjacent bodies spliced ​​together. Each body includes a sheet metal sleeve and an insert. One side of the sheet metal sleeve has a slot for inserting into the insert on an adjacent body, and the other end of the sheet metal sleeve is fixedly connected to the insert. Two parallel first waist-shaped through slots are provided above and below the sheet metal sleeve. The insert has a second waist-shaped through slot aligned with the first waist-shaped through slots. An adjusting screw and an adjusting nut are fitted between the first and second waist-shaped through slots. The adjusting screw passes sequentially through the first waist-shaped through slot above the sheet metal sleeve, the second waist-shaped through slot below the sheet metal sleeve, and then is threadedly connected to the adjusting nut to lock the insert to the sheet metal sleeve. This structure allows for adjustment of the sheet metal part length as required.

[0004] While the above solution can adjust the length of sheet metal parts, the use of adjusting screws and nuts for fixing is prone to slippage and loosening, thus reducing the tightness of the connection between adjacent sheet metal parts. Furthermore, connecting multiple sheet metal parts requires screwing in multiple sets of adjusting screws and nuts, increasing the workload and making the connection process cumbersome, resulting in inconvenient assembly and disassembly. To address these issues, a solution is proposed below. Utility Model Content

[0005] The purpose of this invention is to provide a sheet metal part with adaptive assembly tolerance, which has the advantages of quick disassembly and adjustment of the sheet metal part length and ease of use.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An adaptive assembly tolerance sheet metal part includes several sheet metal parts bodies, with adjacent sheet metal parts bodies interconnected. One end of each sheet metal part body is fixedly provided with a plug-in block, and the other end of each sheet metal part body is provided with a plug-in groove, which mates with the plug-in block. Each plug-in block has grooves on both sides, and a fixed shaft is fixedly provided in each groove. A rotatable abutment block passes through the fixed shaft. A abutment spring is connected between one side of the abutment block and the inner wall of the groove. Each plug-in groove has abutment slots on both sides, which mate with the abutment block. A push-reset mechanism is also provided within each plug-in block, which mates with the abutment block. A threaded hole is provided at the upper end of each plug-in block body, and a locking mechanism is provided at the upper end of each sheet metal part body, which mates with the threaded hole.

[0008] Preferably, the push-reset mechanism includes two push columns, and the insertion block is provided with two sliding grooves. One end of each push column is located on one side of the abutment block. A reset spring is provided in each sliding groove, and the two ends of the reset spring are respectively connected between the inner wall of the sliding groove and one side of the push column. A push groove is also provided on one side of the sheet metal body, and the push groove communicates with the insertion groove. The top of the push column is higher than the top of the insertion block, and the push groove cooperates with the push column. A through groove is also provided at the top of the sheet metal body, and the through groove communicates with the push groove.

[0009] Preferably, the locking mechanism includes a locking screw, the upper end of the sheet metal body is provided with a mounting hole, and the locking screw passes through the mounting hole, while the lower end of the locking screw is located in a threaded hole.

[0010] Preferably, a sealing gasket is provided between two adjacent sheet metal parts. Each sealing gasket includes a left half-circle and a right half-circle. Two insertion holes are provided on one side of the left half-circle, and two insertion posts are provided on one side of the right half-circle. The two insertion posts are respectively engaged with the two insertion holes.

[0011] Preferably, a guide block is provided at the bottom of the insertion slot, and a guide groove is provided on the lower side of the insertion block, and the guide groove cooperates with the guide block.

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

[0013] 1. By inserting the plug into the plug slot and fixing the plug in the plug slot, a fixed connection between two adjacent sheet metal parts can be achieved, thereby adjusting the length of the sheet metal parts. When the plug is inserted into the plug slot, it can push the two clamping blocks to rotate around the fixed axis. At this time, the clamping blocks can enter the groove. At the same time, the clamping spring is compressed and generates elastic force. After the plug enters the plug slot, the clamping spring can drive the clamping blocks back to the initial position, so that one end of the clamping block can be inserted into the clamping groove, thereby fixing the plug and the plug slot, and finally fixing the two adjacent sheet metal parts.

[0014] 2. The locking mechanism increases the tightness between two adjacent sheet metal parts to prevent them from loosening. If it is necessary to disassemble two adjacent sheet metal parts, the sealing gasket can be removed first. Then, the right end of the abutment block can be pushed by the reset mechanism to rotate the right end of the abutment block upward. At this time, the left end of the abutment block rotates upward, so that one end of the abutment block is disengaged from the abutment groove. Then, the sheet metal part can be pulled to pull the plug block out of the plug groove, thus achieving the disassembly of two adjacent sheet metal parts. Attached Figure Description

[0021] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model's concept should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.

[0022] like Figures 1 to 5 As shown, an adaptive assembly tolerance sheet metal part includes several sheet metal part bodies 1, and adjacent sheet metal part bodies 1 are interconnected. One end of the sheet metal part body 1 is fixedly provided with a plug-in block 2, and the other end of the sheet metal part body 1 is provided with a plug-in groove 3. The plug-in groove 3 cooperates with the plug-in block 2. By inserting the plug-in block 2 into the plug-in groove 3 and fixing the plug-in block 2 in the plug-in groove 3, a fixed connection between adjacent sheet metal part bodies 1 can be achieved, thereby realizing the adjustment of the length of the sheet metal part.

[0023] The plug-in block 2 has grooves 4 on both sides, and a fixed shaft 5 is fixed in each groove 4. A rotatable abutment block 6 passes through the fixed shaft 5. A retaining spring 7 is connected between one side of the abutment block 6 and the inner wall of the groove 4. The plug-in slot 3 has abutment slots 8 on both sides, and the abutment slots 8 cooperate with the abutment blocks 6. When the plug-in block 2 is inserted into the plug-in slot 3, it can push the two abutment blocks 6 to rotate around the fixed shaft 5. At this time, the abutment blocks 6 can enter into the groove 4. At the same time, the abutment spring 7 is compressed and generates elastic force. When the plug-in block 2 enters into the plug-in slot 3, the abutment blocks 6 can be driven back to the initial position by the reset action of the abutment spring 7. Thus, one end of the abutment block 6 can be inserted into the abutment slot 8, thereby fixing the plug-in block 2 and the plug-in slot 3. Finally, the fixing between two adjacent sheet metal parts 1 can be achieved.

[0024] A locking mechanism 11 is provided at the upper end of the sheet metal body 1, and a threaded hole 10 is provided at the upper end of the plug-in block 2 body. The locking mechanism 11 cooperates with the threaded hole 10. The locking mechanism 11 can increase the tightness between two adjacent sheet metal body 1s to prevent them from loosening. The locking mechanism 11 includes a locking screw 17. The upper end of the sheet metal body 1 is provided with a mounting hole 18, and the locking screw 17 passes through the mounting hole 18. The lower end of the locking screw 17 is located in the threaded hole 10. After the plug-in block 2 is fixed in the plug-in groove 3, the locking screw 17 can be screwed into the mounting hole 18, so that the lower end of the locking screw 17 is screwed into the threaded hole 10. This can increase the connection strength between the plug-in block 2 and the plug-in groove 3, and further ensure the connection quality between two adjacent sheet metal body 1s.

[0025] A sealing gasket 19 is also provided between two adjacent sheet metal parts 1. Each sealing gasket 19 includes a left half-circle 20 and a right half-circle 21. Two insertion holes 22 are provided on one side of the left half-circle 20, and two insertion posts 23 are provided on one side of the right half-circle 21. The two insertion posts 23 are respectively engaged with the two insertion holes 22. When two adjacent sheet metal parts 1 are fixedly connected, the left half-circle 20 and the right half-circle 21 can be fixed through the engagement between the insertion holes 22 and the insertion posts 23, thereby fixing the sealing gasket 19 between the two adjacent sheet metal parts 1. This allows the two sides of the sealing gasket 19 to fit against one side of the left sheet metal part and one side of the right sheet metal part, respectively. Therefore, the sealing gasket 19 can increase the sealing between the two adjacent sheet metal parts 1 and also play a certain buffering role.

[0026] A guide block 24 is provided at the bottom of the insertion slot 3, and a guide groove 25 is provided on the lower side of the insertion block 2. The guide groove 25 cooperates with the guide block 24. When the insertion block 2 is inserted into the insertion slot 3, the guide block 24 can slide along the guide groove 25. Therefore, the connection position between two adjacent sheet metal parts 1 can be more accurate, thereby increasing the accuracy of the sheet metal parts after connection.

[0027] The plug-in block 2 is also equipped with a push-reset mechanism 9, which cooperates with the clamping block 6. If it is necessary to disassemble the two adjacent sheet metal parts 1, the sealing gasket 19 can be removed first. Then, the right end of the clamping block 6 can be pushed by the push-reset mechanism 9 so that the right end of the clamping block 6 rotates upward. At this time, the left end of the clamping block 6 rotates upward, so that one end of the clamping block 6 is dislodged from the clamping groove 8. Then the sheet metal parts 1 can be pulled to pull the plug-in block 2 out of the plug-in groove 3, and finally the disassembly of the two adjacent sheet metal parts 1 can be achieved.

[0028] The push-reset mechanism 9 includes two push columns 12. Two sliding grooves 13 are provided within the insertion block 2. One end of each push column 12 is located on one side of the abutment block 6. A reset spring 14 is provided within each sliding groove 13, with both ends of the reset spring 14 connected between the inner wall of the sliding groove 13 and one side of each push column 12. A push groove 15 is also provided on one side of the sheet metal body 1, and the push groove 15 communicates with the insertion groove 3. The top of each push column 12 is higher than the top of the insertion block 2, and the push groove 15 cooperates with the push column 12. The upper end of the body 1 is also provided with a through groove 16, which is connected to the push groove 15. When the plug block 2 is inserted into the plug groove 3, the upper end of the push column 12 can slide along the push groove 15. If it is necessary to disassemble the two adjacent sheet metal bodies 1, the two push columns 12 can be moved through the through groove 16, so that the push column 12 moves forward. At this time, the return spring 14 is stretched and generates elastic force, and the push column 12 can push the abutment block 6 to rotate. Then the return spring 14 can be used to reset the push column 12.
