Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts processing technology, and in particular to a spring nut with an anti-misassembly structure. Background Technology
[0002] A leaf nut is a thin-plate nut with a flexible clamping arm. It typically engages with pre-drilled square or rectangular holes in sheet metal via its own elasticity, providing a strong internal thread for subsequent bolting. Its advantages include quick installation, no welding required, and minimal space requirements for back-side operation.
[0003] However, existing spring nuts have a common problem: poor ability to prevent incorrect installation. Traditional spring nuts are often designed to be symmetrical or have indistinct features, making it easy for operators to make the following mistakes during manual or semi-automatic installation: 1. Reverse installation: The threaded hole surface (working surface) of the nut is installed in reverse with the elastic clamping surface, which makes it impossible to fit with the bolt.
[0004] 2. Mixing of different models: Spring nuts with similar appearances but different specifications (such as M3, M4, M5 threads) are easily mixed up.
[0005] 3. Incorrect installation: On components with multiple similar mounting holes, nuts may be installed in the wrong position.
[0006] These assembly errors can range from minor issues like rework and reduced production efficiency to more serious problems like connection failures during product use, creating safety hazards. Utility Model Content
[0007] The purpose of this utility model is to provide a spring nut with an anti-misinstallation structure, which solves the problem that traditional spring nuts are often designed to be symmetrical or have indistinct features, making it easy for operators to install them in the wrong direction, mix up the model, or install them in the wrong position when installing them manually or semi-automatically.
[0008] To achieve the above objectives, this utility model provides a spring nut with an anti-misinstallation structure, including a spoiler frame base; the number of bases is multiple, and the multiple bases are respectively fixedly connected to the spoiler frame and located on the surface of the spoiler frame, each base has a slot on its surface, each slot has an anti-misinstallation groove on its side, and each base has an insertion hole on its front.
[0009] Each of the slots has a receiving groove on its surface.
[0010] The spring nut with anti-misinstallation structure further includes multiple spring nuts, which are detachably connected to the base and pass through the base respectively.
[0011] The spring nut with anti-misalignment structure further includes an anti-misalignment block and a barb. Each spring nut has an anti-misalignment block on its outer side and a barb fixedly connected to its inner side.
[0012] Each of the spring nuts has a limiting groove on its surface.
[0013] This utility model features a spring nut with an anti-misinstallation structure. Through structural interference, it prevents incorrect installation, eliminating the possibility of human error and improving assembly quality and reliability. The anti-misinstallation feature is formed in one piece using a stamping process, adding almost no raw material or manufacturing costs. Different shapes and positions of the anti-misinstallation structure can be flexibly designed, creating a unique "anti-misinstallation code" for different product lines and nut specifications, preventing mixed installations, simplifying assembly operations, reducing the experience and attention requirements of operators, and improving overall production efficiency. The anti-misinstallation structure also provides initial guidance and positioning during correct installation, making installation smoother. It solves the problem that traditional spring nuts are often designed to be symmetrical or have indistinct features, making it easy for operators to install them in the wrong direction, mix up models, or misplace them during manual or semi-automatic installation.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0020] The first embodiment of this application is as follows: Please see Figures 1 to 3 ,in, Figure 1 This is a schematic diagram of the overall structure of the spring nut with anti-misassembly structure according to the first embodiment of this utility model. Figure 2 This is a schematic diagram of the base structure according to the first embodiment of this utility model. Figure 3 This is a schematic diagram of the structure of the spring nut of the first embodiment of the present invention. The present invention provides a spring nut with an anti-misinstallation structure, including a spoiler frame 101, a base 102, a spring nut 103, an anti-misinstallation block 104, and a barb 105. The aforementioned solution solves the problem that traditional spring nuts are often designed to be symmetrical or have indistinct features, making it easy for operators to install them in the wrong direction, mix up the model, or install them in the wrong position when installing them manually or semi-automatically.
[0021] In this specific embodiment, there are multiple bases 102, each fixedly connected to the spoiler frame 101 and located on the surface of the spoiler frame 101. Each base 102 has a slot 106 on its surface, and each slot 106 has a misalignment prevention groove 107 on its side. Each base 102 has an insertion hole 108 on its front. The base 102 has a U-shaped groove structure with an asymmetrical structure (e.g., one side is a straight edge, the other side has a groove) to provide support and limit the spring nut 103. The slot 106 provides a limit to the upper plate of the spring nut 103. The misalignment prevention groove... The slot 107 cooperates with the anti-misalignment block 104 to prevent the spring nut 103 from being installed in reverse. The insertion hole 108 is used to accommodate the lower plate of the spring nut 103. Through structural interference, the "misalignment cannot be prevented" condition is achieved, eliminating the possibility of human error and improving assembly quality and reliability. The anti-misalignment feature is formed in one piece by stamping process, which hardly increases the raw materials and manufacturing costs. Different shapes and positions of anti-misalignment structures can be flexibly designed to create a unique "anti-misalignment code" for nuts of different product lines and specifications, preventing mixed assembly, simplifying assembly operations, reducing the requirements for operator experience and attention, and improving overall production efficiency. The anti-misalignment structure can also play a preliminary guiding and positioning role when correctly installed, making the installation smoother.
[0022] Each of the slots 106 has a receiving groove 109 on its surface. The receiving groove 109 is used to accommodate the upper plate of the spring nut 103 and prevent the spring nut 103 from shifting during use.
[0023] Secondly, there are multiple spring nuts 103. Each spring nut 103 is detachably connected to the base 102 and passes through the base 102. The spring nut 103 is fitted to the base 102, and its shape matches the base 102. It can only be embedded in the base 102 in a single direction.
[0024] Furthermore, each of the spring nuts 103 has an anti-misalignment block 104 on its outer side and a barb 105 fixedly connected to its inner side. The anti-misalignment block 104 cooperates with the anti-misalignment groove 107 to limit the movement of the spring nut.
[0025] Finally, each of the spring nuts 103 has a limiting groove 110 on its surface, which is used to limit the bolt.
[0026] Using the spring nut with anti-misinstallation structure in this embodiment, the "misinstallation will not occur" is achieved through structural interference, eliminating the possibility of human error, improving assembly quality and reliability. The anti-misinstallation feature is formed in one piece through a stamping process, which increases raw material and manufacturing costs by almost nothing. Different shapes and positions of anti-misinstallation structures can be flexibly designed to create a unique "anti-misinstallation code" for nuts of different product lines and specifications, preventing mixed installation, simplifying assembly operations, reducing the experience and attention requirements of operators, and improving overall production efficiency. The anti-misinstallation structure can also play a preliminary guiding and positioning role when installed correctly, making installation smoother. It solves the problem that traditional spring nuts are often designed to be symmetrical or have indistinct features, making it easy for operators to install them in the wrong direction, mix up the models, or install them in the wrong position when installing manually or semi-automatically.
[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
