Description

Technical Field

[0001] This utility model relates to the field of plastic part connection technology, and in particular to a detachable snap-fit ​​structure for connecting plastic parts. Background Technology

[0002] With social development and industrial progress, product requirements are becoming increasingly stringent. Not only are functional needs rising, but product appearance and delivery speed are also becoming criteria for customer selection. When multiple products on the market meet functional requirements, a more aesthetically pleasing product has an advantage. Products that conventionally use screw connections have visible screw holes, offering less protection and a less attractive appearance. If the product operates under harsh conditions with high protection requirements, the screw areas need separate protective treatment. Bolted connections require additional tools, resulting in low production efficiency, inconvenient installation, and increased costs. Furthermore, on-site after-sales maintenance is difficult due to disassembly and assembly issues, and there is a risk of screw loss. Utility Model Content

[0003] The purpose of this utility model is to provide a detachable snap-fit ​​structure for connecting plastic parts, so as to solve the problems encountered in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A detachable snap-fit ​​structure for connecting plastic parts includes a first connector and a second connector, both made of elastic plastic. The first connector has a snap-fit ​​at its mounting end, and a deformation groove is provided between the snap-fit ​​and the first connector to accommodate the deformation of the snap-fit. The second connector has a fastening gap on its mounting end face, and an external protrusion in the fastening gap abuts against the snap-fit.

[0006] In the above solution, the outer side of the buckle is provided with a protruding locking block, the top of which is platform-shaped; after the first connecting member and the second connecting member are connected, the buckle abuts against the bottom of the protruding platform through the locking block. As a preferred solution, the contact length between the locking block and the protruding platform is smaller than the length of the deformable groove.

[0007] In the above solution, the bottom of the mounting end of the first connector is integrally connected to the bottom of the buckle via a connecting root, and the connecting root has an arc-shaped structure; the deformable groove is located in the space formed by the mounting end face of the first connector, the top of the connecting root, and the inner side of the buckle. As a preferred solution, the top of the buckle is provided with a lever, and the top of the lever is flush with the top of the outer boss.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: A buckle is provided at the mounting end of the first connector, and a deformation groove is provided between the buckle and the first connector to accommodate the deformation of the buckle. A fastening gap is provided on the mounting end face of the second connector, and an outer protrusion abuts against the buckle within the fastening gap. When the first and second connectors are connected, the buckle deforms towards the deformation groove and then engages downwards with the outer protrusion. Because of the design of the deformation groove to accommodate the deformation of the buckle, the first and second connectors can be easily engaged. Furthermore, this engagement is a detachable connection, facilitating disassembly for later maintenance. The biggest advantage of this buckle connection is its ease of installation and disassembly, allowing for tool-free disassembly, maintaining the integrity of the product's appearance, saving on the cost of product connectors, and improving product production efficiency.

[0014] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the utility model will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of this utility model, and therefore only show the relevant components of this utility model.

[0015] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0016] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 As shown, a detachable snap-fit ​​structure for connecting plastic parts includes a first connector 1 and a second connector 2. Both the first connector 1 and the second connector 2 are made of elastic plastic and can be used in the housing of electronic devices. For example, when the first connector 1 is a top cover, the second connector 2 is a bottom cover; when the first connector 1 is a support plate, the second connector 2 can be a bracket for mounting the support plate, with a mounting groove for the support plate pre-drilled in the middle of the bracket.

[0018] A buckle 11 is provided at the mounting end of the first connector 1. A deformation groove 12 is provided between the buckle 11 and the first connector 1 to accommodate the deformation of the buckle 11. A fastening gap 21 is provided on the mounting end face of the second connector 2. An outer boss 22 abuts against the buckle 11 in the fastening gap 21. When the first connector 1 and the second connector 2 are connected, the buckle 11 deforms towards the deformation groove 12 and then snaps downward onto the outer boss 22. Because the deformation groove 12 is designed to accommodate the deformation of the buckle 11, the first connector 1 and the second connector 2 can be easily snapped together. Moreover, this snap-fit ​​connection is detachable, which is convenient for disassembly during later maintenance.

[0019] In practice, the buckle 11 has a protruding locking block 13 on its outer side. The top of the locking block 13 is platform-shaped, and the bottom is slanted, which serves to strengthen the support. After the first connector 1 and the second connector 2 are connected, the buckle 11 abuts against the bottom of the protrusion 22 through the locking block 13, thereby fastening together.

[0020] As a preferred solution, the contact length between the locking block 13 and the outer protrusion 22 is less than the length of the deformable slot 12. The contact area between the locking block 13 and the outer protrusion 22 is the engagement amount. This locking structure must have sufficient deformation space for disassembly and assembly, and the engagement amount must be sufficient to facilitate installation and disassembly. Generally, when using this solution in the housing of a small controller, it is recommended that the contact length between the locking block 13 and the outer protrusion 22 be between 0.35-1mm, and the length of the deformable slot 12 should be greater than this value.

[0021] In implementation, the bottom of the mounting end of the first connector 1 is integrally connected to the bottom of the buckle 11 via a connecting root 14. The connecting root 14 is an arc-shaped structure at a right angle, with one end connected to the mounting end of the first connector 1 and the other end connected to the vertically positioned buckle 11. The deformation slot 12 is located in the space formed by the mounting end face of the first connector 1, the top of the connecting root 14, and the inner side of the buckle 11, thereby giving the buckle 11 a certain degree of elasticity. The deformation slot 12 also provides space for the deformation of the buckle 11.

[0022] As a preferred embodiment, a lever 15 is provided at the top of the buckle 11, and the top of the lever 15 is flush with the top of the outer protrusion 22. During installation, pressing the lever 15 can fasten the first connector 1 and the second connector 2 together. During disassembly, the buckle 11 can be disengaged from the bottom of the outer protrusion 22 by moving the lever 15 into the deformable slot 12, thereby separating the first connector 1 and the second connector 2.

[0023] This solution addresses the shortcomings of existing technologies by incorporating a snap-fit ​​structure directly into the product itself, eliminating the need for additional locking components such as screws and nuts, thus saving costs. The entire assembly process is simple, requiring only a simple insertion action to complete the snap-fit ​​assembly of two or more parts. Simultaneously, the snap-fit ​​structure increases product strength, and the snap-fit ​​connection is one of the connection methods that maintains the integrity of the product's appearance, making it suitable for consumer electronics products where high aesthetic requirements exist.

[0024] The biggest feature of this snap-fit ​​connection is that it is easy to install and disassemble. It can be disassembled without tools. By turning the lever 15, the first connector 1 and the second connector 2 can be separated, which can maintain the integrity of the product's appearance and save on the cost of the product connectors.
