Description

Technical Field

[0001] The present invention relates to the technical field of the housing fixing structure of electronic products, and particularly relates to an internal detachable snap fixing structure. Background Art

[0002] At present, the fixing of protective covers such as side covers and end covers of electronic products on the market mostly adopts methods such as glue bonding, screw fixing, and snap fixing.

[0003] The following defects exist in the prior art:

[0004] 1. Components that need to be repaired are often installed inside the protective cover. Among them, although the glue bonding method is simple and convenient to install, it is difficult to disassemble and reassemble after bonding and assembly. Therefore, it is limited to the fixing of protective covers that do not need to be disassembled after assembly. When the protective cover is fixed with screws, most assembly strength requirements can be met. However, when fixed with multiple screws, the disassembly is cumbersome and the difficulty of the appearance design is increased.

[0005] 2. The ordinary snap structure is composed of a hook and a slot. When the snap is latched, the hook deforms and enters the slot, and after the hook resumes its shape, the latching is completed, forming a fixed connection relationship with the slot. When the product protective cover is only fixed with this ordinary snap structure, it is difficult to disassemble after being snapped in. When repairing and replacing internal parts, it must be forcibly disassembled from the slot, which is likely to cause the hook to break or be permanently deformed and damaged, and cannot be used again. Summary of the Invention

[0006] In order to overcome the deficiencies of the prior art, one of the purposes of the present invention is to provide an internal detachable snap fixing structure, which can solve problems such as unreliable product connection structures and inconvenient disassembly and assembly, and greatly improve the integrity and plasticity of the product appearance design.

[0007] One of the purposes of the present invention is achieved by adopting the following technical solutions:

[0008] An internal detachable snap fixing structure includes a housing assembly and a protective cover assembly. The housing assembly includes a housing, a hook support, a thimble combination structure, and a hook lever. The hook support is installed on the housing. The housing is provided with a side wall mounting hole for passing through the thimble combination structure. U-shaped hooks and ordinary hooks are respectively arranged on both sides of the hook support. The protective cover assembly includes a slot support and a protective cover. The slot support is installed on the protective cover. The slot support is provided with a plurality of slots matching the U-shaped hooks and the ordinary hooks. One end of the thimble combination structure is embedded in the side wall mounting hole, and the other end abuts against the hook lever. The hook lever is clamped to the hook support. By pressing the thimble combination structure, the hook lever drives the hook support to move, so that the U-shaped hook is disengaged from the slot.

[0009] Furthermore, the U-shaped hook and the ordinary hook are symmetrically distributed on both sides of the main body of the hook bracket.

[0010] Furthermore, the hook bracket includes a main body of the hook bracket, and the U-shaped hook and the ordinary hook are installed on both sides of the main body of the hook bracket.

[0011] Furthermore, the U-shaped hook and the ordinary hook are respectively perpendicular to the main body of the hook bracket.

[0012] Furthermore, the thimble combination structure is perpendicular to the main body of the hook bracket.

[0013] Furthermore, the thimble combination structure includes a thimble, a spring and a spring retaining piece. The spring and the spring retaining piece are installed on the thimble. One side of the spring retaining piece is in contact with the spring, and the other side is in contact with the inner side wall of the housing. One end of the thimble is embedded in the side wall mounting hole, and the other end abuts against the hook lever.

[0014] Furthermore, an installation groove is provided on the U-shaped hook, and a card joint that is clamped with the installation groove is provided on the hook lever. The card joint is perpendicular to the U-shaped hook.

[0015] Furthermore, the housing is provided with a plurality of limit holes, and the protective cover is provided with a plurality of limit posts that match the limit holes.

[0016] Furthermore, the housing is provided with a plurality of fixed threaded holes for fixedly connecting the hook bracket structure.

[0017] Furthermore, the hook bracket is provided with a wire groove position, a lever support rib plate and a lever limit rib plate. The circuits in the internal components are arranged along the wire groove position, and the hook lever is placed on the lever support rib plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] The slot bracket is installed on the protective cover, and the slot bracket is provided with a plurality of slots matching the U-shaped hook and the ordinary hook; one end of the ejector assembly structure is embedded in the side wall mounting hole, and the other end is against the hook lever, and the hook lever is connected to the hook bracket. By pressing the ejector assembly structure, the hook lever drives the hook bracket to deform, thereby causing the U-shaped hook to disengage from the slot. In actual use, the end of the ejector assembly structure is pushed by a small screwdriver or other tool so that the hook lever pulls the U-shaped hook on one side of the hook bracket. Since the U-shaped hook has a good elastic arm, the U-shaped hook is smoothly disengaged from the slot after deformation. The product protective cover structure can be opened by pushing away the disengagement side of the protective cover assembly, which can ensure the reliability of the fixed connection and facilitate disassembly. The overall buckle fixing structure is installed and fixed in a built-in manner to improve the integrity and plasticity of the shell appearance.
