Technical Field

[0001] The utility model relates to a sheet metal part, in particular to a sheet metal part which is convenient for stable connection and belongs to the technical field of sheet metal parts. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates. Sheet metal processes include shearing, punching / cutting, folding, welding, riveting, splicing, forming, etc. Its most notable feature is that the thickness of the same part is consistent. The product processed by sheet metal technology is a sheet metal part.

[0003] Most commonly used sheet metal parts are spliced ​​and fixed by bolts. Although bolt connection is relatively stable, the bolt fixing method is cumbersome in installation and disassembly operations, which is not convenient for fast splicing of sheet metal parts. In addition, the staff also need to use tools to remove multiple bolts before disassembling the sheet metal parts, resulting in very low processing efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a sheet metal part that is easy to connect stably. By setting a snap-fit ​​positioning mechanism, a snap-fit ​​method is used instead of bolts to splice and fix the first sheet metal part and the second sheet metal part. Positioning can be performed before splicing, making the splicing of the two sheet metal parts more stable and quick.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A sheet metal part that is convenient for stable connection, comprising a first sheet metal part and a second sheet metal part, wherein a snap-fit ​​positioning mechanism is arranged on the first sheet metal part, and the snap-fit ​​positioning mechanism comprises a plurality of positioning cylinders symmetrically fixedly installed on both sides of the first sheet metal part, positioning rods are arranged on both sides of the second sheet metal part, a plurality of fixing frames are symmetrically fixedly installed inside the first sheet metal part, a fixing plate is fixedly installed inside the fixing frame, springs are arranged on both sides of the fixing plate, a clamping block is arranged at one end of the spring, and a plurality of clamping grooves that are mutually clamped with the clamping block are arranged at the bottom of the second sheet metal part.

[0007] Furthermore, the shape of the clamping block is set to be a right-angled trapezoid, and the bottom of the positioning rod is set to be conical.

[0008] Furthermore, mounting plates are installed at both ends of the spring, and the two mounting plates are fixedly connected to the fixing plate and the clamping block.

[0009] Furthermore, a plurality of empty slots are provided on both sides of the fixing frame, and a plurality of push rods extending to the outside of the empty slots are fixedly mounted on both sides of the clamping block.

[0010] Furthermore, a threaded rod is fixedly mounted on the top of the positioning rod, and a plurality of threaded grooves for use with the threaded rod are formed on the second sheet metal component.

[0011] Furthermore, the bottom of the positioning rod is provided with anti-slip grooves.

[0012] Furthermore, a plurality of balls are evenly mounted on the positioning rod, and the balls fit the inner wall of the positioning tube.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The present application realizes the splicing of the first sheet metal part and the second sheet metal part by setting a snap-fit ​​positioning mechanism. During splicing, the positioning rods on both sides of the second sheet metal part are inserted into the positioning cylinder to play a role of pre-positioning, and then the second sheet metal part is pressed downward so that its bottom contacts the fixed frame. The clamping block in the fixed frame is squeezed and contracted by the second sheet metal part. When the clamping slot at the bottom of the second sheet metal part drops to a horizontal position with the clamping block, the clamping block extends and clamps in the clamping slot under the elastic reset of the spring. The splicing of the first sheet metal part and the second sheet metal part is completed by the clamping of the clamping block and the clamping slot and the positioning of the positioning cylinder and the positioning rod. It is not only convenient to operate and does not require the use of tools, but also can be positioned before splicing, so that the splicing of the first sheet metal part and the second sheet metal part is more stable and quick, convenient to use and improves work efficiency.

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figure 1-Figure 4As shown, a sheet metal part that is convenient for stable connection includes a first sheet metal part 1 and a second sheet metal part 2. The first sheet metal part 1 is provided with a snap-fit ​​positioning mechanism 3, which includes a plurality of positioning cylinders 4 symmetrically fixedly installed on both sides of the first sheet metal part 1, and positioning rods 5 are provided on both sides of the second sheet metal part 2. A plurality of fixing frames 6 are symmetrically fixedly installed inside the first sheet metal part 1, and a fixing plate 7 is fixedly installed inside the fixing frame 6. Springs 8 are provided on both sides of the fixing plate 7, and a clamping block 9 is provided at one end of the spring 8. The bottom of the second sheet metal part 2 is provided with a plurality of clamping grooves 10 that are engaged with the clamping block 9. The arrangement of the engaging and positioning mechanism 3 facilitates the splicing of the first sheet metal part 1 and the second sheet metal part 2. During the splicing, the positioning rods 5 on both sides of the second sheet metal part 2 are inserted into the positioning cylinder 4 to play a role of pre-positioning. The second sheet metal part 2 is pressed downward so that its bottom contacts the fixing frame 6. The clamping block 9 in the fixing frame 6 is squeezed and contracted by the second sheet metal part 2. When the clamping groove 10 at the bottom of the second sheet metal part 2 drops to a horizontal position with the clamping block 9, the clamping block 9 extends and engages in the clamping groove 10 under the elastic reset of the spring 8. The splicing of the first sheet metal part 1 and the second sheet metal part 2 is completed by the engagement of the clamping block 9 and the clamping groove 10 and the positioning of the positioning cylinder 4 and the positioning rod 5. The operation is convenient and does not require the use of tools. At the same time, positioning can be performed before splicing, so that the splicing of the first sheet metal part 1 and the second sheet metal part 2 is more stable and quick, which is convenient to use and improves work efficiency.

[0022] The shape of the clamping block 9 is set to a right-angled trapezoid, and the bottom of the positioning rod 5 is set to a cone; mounting plates 11 are installed at both ends of the spring 8, and the two mounting plates 11 are fixedly connected to the fixing plate 7 and the clamping block 9 by multiple bolts; multiple empty slots 12 are opened on both sides of the fixing frame 6, and multiple push rods 13 extending to the outside of the empty slots 12 are fixedly installed on both sides of the clamping block 9. By setting the shape of the block 9 to a right-angled trapezoid and making one side of it inclined, it is easier to squeeze the block 9 at its bottom when installing the second sheet metal part 2, and the installation is convenient. The bottom of the positioning rod 5 is set to a cone, so that the diameter of its bottom becomes smaller, so that it is easier to insert into the positioning tube 4; the spring 8 can be installed between the fixed plate 7 and the block 9 through the mounting plate 11 and the bolt, so that the spring 8 can be removed from between the fixed plate 7 and the block 9, which is convenient for replacement when it is damaged or broken; by setting the empty slot 12 and the push rod 13, the push rod 13 extends to the outside of the fixed frame 6, which can make it easier to push the block 9 to separate from the slot 10 when disassembling the first sheet metal part 1 and the second sheet metal part 2.

[0023] The top of the positioning rod 5 is fixedly mounted with a threaded rod 14, and the second sheet metal part 2 is provided with a plurality of threaded grooves 15 for use with the threaded rod 14; the bottom of the positioning rod 5 is provided with an anti-skid pattern 16; a plurality of balls 17 are evenly mounted on the positioning rod 5, and the balls 17 fit the inner wall of the positioning tube 4. The positioning rod 5 is mounted on the second sheet metal part 2 through the threaded rod 14 and the threaded groove 15, which not only makes the connection between the positioning rod 5 and the second sheet metal part 2 firmly prevent it from falling off, but also allows the positioning rod 5 to be disassembled and replaced when it is damaged; the anti-skid pattern 16 can increase the friction force on the surface of the positioning rod 5, making it easier to twist the positioning rod 5 for installation and disassembly; through the arrangement of the balls 17, the friction force between the positioning rod 5 and the positioning tube 4 can be reduced by the rolling of the plurality of balls 17, making it easier for the second sheet metal part 2 to fall during installation.

[0024] The working process of a sheet metal part that is convenient for stable connection provided in this embodiment is as follows:

[0025] During splicing, inserting the positioning rods 5 on both sides of the second sheet metal part 2 into the positioning cylinder 4 can play a role of pre-positioning, and then pressing the second sheet metal part 2 downward so that its bottom contacts the fixed frame 6, and the block 9 in the fixed frame 6 is squeezed and contracted by the second sheet metal part 2. When the slot 10 at the bottom of the second sheet metal part 2 drops to a horizontal position with the block 9, the block 9 extends and engages in the slot 10 under the elastic reset of the spring 8, thereby completing the splicing of the first sheet metal part 1 and the second sheet metal part 2 through the engagement of the block 9 and the slot 10 and the positioning of the positioning cylinder 4 and the positioning rod 5. It is not only convenient to operate and does not require the use of tools, but also can be positioned before splicing.

[0026] The above description shows and describes the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein, and modifications and changes made by those skilled in the art without departing from the spirit and scope of the present invention should be within the scope of protection of the claims attached to the present invention.
