Description

Technical Field

[0001] This utility model relates to the field of sheet metal technology, and more specifically, it relates to a quick snap-fit ​​and separation structure for sheet metal parts. Background Technology

[0002] In fields such as machinery manufacturing, automobile assembly, and home appliance production, sheet metal parts, with their lightweight, high strength, and easy-to-form characteristics, enable interconnection and positioning to ensure the stability of the overall structure and assembly accuracy. The core function of these sheet metal connection components is to quickly connect and position and limit displacement during use.

[0003] Common sheet metal connection structures are mostly barbed snaps or interference fit slots. However, barbed snaps require tools to pry them apart, which is not only time-consuming but also prone to snap breakage or deformation of the sheet metal edge, increasing maintenance costs. Although interference fit slots are easy to assemble, they require a large pulling force to separate, which can easily damage the coating on the surface of the sheet metal.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quick snap-fit ​​and separation structure for sheet metal parts.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick snap-fit ​​and separation structure for sheet metal parts, including a snap-fit ​​and separation structure body, the snap-fit ​​and separation structure body including a limiting component and a connecting component, the limiting component including a base plate, a rotating rod, a support block, a limiting block and a rotating plate, the rotating plate being rotatably connected to the rotating rod. The connecting assembly includes a side plate, a second rotating rod, a connecting plate, a support rod, and a spring. The connecting plate is rotatably connected to the second rotating rod. The spring is sleeved on the support rod, and its two ends are fixedly connected to the side plate and the connecting plate, respectively. When the connecting plate moves to abut against the top of the limiting block, it flips upward and drives the spring to stretch. When the connecting plate passes the limiting block, it is driven by the elasticity of the spring to flip downward and engage with the limiting block. When the connecting plate moves above the bottom plate in a direction close to the support block, it pushes the rotating plate to flip in a direction away from the limiting block. When the connecting plate passes the rotating plate and moves in a direction close to the limiting block, it pulls the rotating plate to flip in a direction away from the support block.

[0007] The present invention is further configured such that: the support block and the limiting block are fixedly connected to the top surface of the base plate, and the width of the rotating plate is greater than the distance between the rotating rod and the limiting block or the support block.

[0008] The present invention is further configured such that: the cross-section of the limiting block is L-shaped, the top two sides of the limiting block are arc-shaped, the top surface of the support block is arc-shaped, the cross-section of the connecting plate is J-shaped, and the side of the connecting plate away from the side plate is arc-shaped.

[0009] The present invention is further configured such that: the height of the limiting block is higher than the height of the rotating rod and the support block, and the distance between the side of the connecting plate away from the side plate and the spring is greater than the distance between the limiting block and the support block.

[0010] The present invention is further configured such that: one end of the support rod is fixedly connected to the side of the side plate near the bottom plate, and the end of the support rod away from the side plate is inclined upward and abuts against the bottom surface of the connecting plate.

[0011] The present invention is further configured such that: two connecting blocks 1 are symmetrically fixed on the top surface of the base plate, and the two ends of the rotating rod 1 are respectively rotatably connected to the two connecting blocks 1; two connecting blocks 2 are symmetrically fixed on the side of the side plate near the base plate, and the two ends of the rotating rod 2 are respectively rotatably connected to the two connecting blocks 2.

[0012] In summary, this utility model has the following beneficial effects: 1. Through a clever lever and spring linkage design, the connecting plate can automatically complete the engagement and disengagement during movement. The entire process does not require external tools, making operation simple and quick. It effectively avoids the problems of traditional barbed clips that require prying and are prone to breakage, or interference fits that require strong pulling, which can damage sheet metal parts and coatings. This protects the integrity of parts and reduces maintenance costs.

[0013] 2. By using the L-shaped limiting block and the J-shaped connecting plate to interlock with each other, and with the elastic pressing action of the spring, a stable multi-point constraint is formed to prevent accidental loosening during use. The setting of the rotating plate further increases the controllability and unidirectionality of the separation operation.

[0014] 3. The top of the limiting block, the top surface of the support block, and the contact side of the connecting plate are all designed with arc shape, which provides a smooth transition and guidance for the movement of the connecting plate, reduces the frictional resistance of the parts during the snapping and separation process, and makes the operation smoother.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example: A quick-connect and disconnect structure for sheet metal parts, such as... Figures 1-4 As shown, the device includes a snap-fit ​​separation structure body 1, which includes a limiting component 2 and a connecting component 3 that cooperate with each other. The limiting component 2 includes a base plate 201, a rotating rod 202, a support block 203, a limiting block 204, and a rotating plate 205. Two connecting blocks 4 are symmetrically fixed on the top surface of the base plate 201. The two ends of the rotating rod 202 are rotatably connected to the two connecting blocks 4 respectively. The rotating plate 205 is rotatably connected to the rotating rod 202. The support block 203 and the limiting block 204 are fixedly connected to the top surface of the base plate 201. The rotating rod 202 is located between the support block 203 and the limiting block 204. The width of the rotating plate 205 is greater than the distance between the rotating rod 202 and the limiting block 204 or the support block 203, so that the rotating rod can rotate between the support block 203 and the limiting block 204 when it is under force, and the side away from the rotating rod after rotation can abut against the top of the support block 203 or the limiting block 204.

[0019] like Figures 1-4 As shown, the connecting assembly 3 includes a side plate 301, a rotating rod 302, a connecting plate 303, a support rod 304, and a spring 305. Two connecting blocks 5 are symmetrically fixed on the side of the side plate 301 near the bottom plate 201. The two ends of the rotating rod 302 are rotatably connected to the two connecting blocks 5 respectively. The connecting plate 303 is rotatably connected to the rotating rod 302. The spring 305 is sleeved on the support rod 304, and the two ends of the spring 305 are fixedly connected to the side plate 301 and the connecting plate 303 respectively, so that when the connecting plate 303 rotates, it can drive the spring 305 to move forward. The telescopic mechanism has an L-shaped cross-section for the limiting block 204, with both top sides of the limiting block 204 being arc-shaped. The connecting plate 303 has a J-shaped cross-section, with the side of the connecting plate 303 away from the side plate 301 being arc-shaped. When the connecting plate 303 moves to abut against the top of the limiting block 204, it is supported by the limiting block 204 and flips upward, driving the spring 305 to stretch. When the connecting plate 303 passes the limiting block 204, it is driven by the elasticity of the spring 305 to flip downward and engage with the limiting block 204, thereby restricting the movement of the connecting plate 303 in the direction away from the bottom plate 201.

[0020] like Figures 1-4 As shown, when the connecting plate 303 moves above the base plate 201 in the direction close to the support block 203, it pushes the rotating plate 205 to flip in the direction away from the limiting block 204 until it abuts against the top of the support block 203. When the connecting plate 303 passes the rotating plate 205, one arc-shaped end of the connecting plate 303 hooks onto one side of the rotating plate 205. At this time, when the connecting plate 303 moves in the direction close to the limiting block 204, it can pull the rotating plate 205 to flip in the direction away from the support block 203 until it abuts against the top of the limiting block 204. The connecting plate 303 can move out from above the limiting block 204 along the inclined surface of the rotating plate 205, thereby achieving the separation of the limiting component 2 and the connecting component 3. Through the ingenious linkage design of the lever and spring 305, the connecting plate 303 can automatically complete the engagement and disengagement during the movement. The whole process does not require the use of external tools, and the operation is simple and quick. It effectively avoids the problems of traditional barbed buckles that are easy to break by prying or interference fits that require strong pulling, which can cause damage to sheet metal parts and coatings. It protects the integrity of parts and reduces maintenance costs.

[0021] like Figures 1-4 As shown, one end of the support rod 304 is fixedly connected to the side plate 301 near the bottom plate 201. The end of the support rod 304 away from the side plate 301 is inclined upward and abuts against the bottom surface of the connecting plate 303. The support rod 304 can provide support for the connecting plate 303 when the connecting assembly 3 is separated from the limiting assembly 2. The height of the limiting block 204 is higher than the height of the rotating rod 202 and the support block 203, which prevents the moving block from abutting against the rotating rod 202 and the support block 203. The distance between the side of the connecting plate 303 away from the side plate 301 and the spring 305 is greater than the distance between the limiting block 204 and the support block 203, thus... The movement distance of the moving block above the base plate 201 is guaranteed. The top surface of the support block 203 is arc-shaped. The L-shaped limit block 204 and the J-shaped connecting plate 303 are interlocked with each other. With the elastic pressing action of the spring 305, a stable multi-point constraint is formed to prevent accidental loosening during use. The setting of the rotating plate 205 further increases the controllability and unidirectionality of the separation operation. The top of the limit block 204, the top surface of the support block 203 and the contact side of the connecting plate 303 are all arc-shaped, which provides a smooth transition and guidance for the movement of the connecting plate 303, reduces the frictional resistance of the parts during the interlocking and separation process, and makes the operation smoother.

[0022] Working principle: Pushing the side plate 301 drives the connecting plate 303 to move along the direction close to the limiting block 204. When the connecting plate 303 moves above the limiting block 204, it is supported by the limiting block 204 and flips upward. At this time, the spring 305 is stretched. When the connecting plate 303 continues to move until one end of the arc passes the limiting block 204, the elastic recovery and contraction of the spring 305 causes the connecting plate 303 to flip downward. When a force is applied to the side plate 301 again in a direction away from the limiting block 204, the limiting block 204 and the connecting plate 303 are engaged with each other, completing the connection operation of the limiting component 2 and the connecting component 3. 301 applies a force close to the support block 203. At this time, the connecting plate 303 pushes the rotating plate 205 to rotate synchronously during the movement until the arc-shaped end of the connecting plate 303 passes the rotating plate 205. Then, a force is applied to the side plate 301 away from the support block 203. During the movement, the arc-shaped end of the connecting plate 303 hooks onto one side of the rotating plate 205, causing the rotating plate 205 to rotate until it abuts against the top of the limiting block 204. At this time, the connecting plate 303 moves out from above the limiting block 204 along the inclined surface of the rotating plate 205, completing the separation operation of the limiting component 2 and the connecting component 3.
