Description

Clamping structure

The invention relates to a snap structure.

Due to the increasingly miniaturization and multi-functionality of electronic products, powerful electronic products often need to integrate multiple components, and various components may belong to different technical fields. Therefore, various components are often manufactured by different manufacturers. Manufacturing, and finally using the housing for integrated assembly. Therefore, the assembly structure between different components is particularly important for the overall performance of electronic products, which is based on the assembled structure of the housing.

In the design of the assembly structure of the housing, the use of hooks is a relatively common method. In the existing hook structure, in order to achieve the engagement within a certain size range, the hook and the card slot are usually used.

In many cases, such a snap-fit structure tends to be loose due to the fact that the hooks are not tightly engaged and the hooks are automatically released. Therefore, when the existing hook structure is applied, other locking structures and components, such as locking screws, are usually attached to ensure the stability of the snap.

However, this method of attaching other locking structures and components can reduce the automatic release of the hooks, but on the one hand, it increases the cost of materials, working hours, operations, etc., on the other hand, the structure and assembly between the components. More and more complicated.

In view of this, it is necessary to provide a snap-fit structure that is not easy to loose and has a simple structure.

A snap structure comprising: a casing, a fastener and a gasket; The housing includes an upper surface and a lower surface, and an upper surface of the housing is formed with an inwardly recessed engaging portion, and the engaging portion is provided with at least one guiding slot and the guiding slot At least one fixing slot is spaced apart; the fastener comprises a bottom surface, and a guiding hook and a fixing hook corresponding to the guiding slot and the fixing slot are formed on the bottom surface, and the guiding hook is The fixing hook has the same extending direction on the bottom surface; the spacer includes a guiding protrusion; the fastening member is fixed on the upper surface of the housing, and the guiding hook and the fixing hook are respectively respectively The guiding slot and the fixing slot; the spacer is fixed on the lower surface of the housing, and the guiding protrusion abuts against the guiding hook.

Compared with the prior art, the engaging structure is biased against the guiding hook by the guiding protrusion, so that the locking between the guiding hook and the fixing hook and the guiding card slot and the fixing slot is tighter. Therefore, the fastener is not easily detached from the casing, and the entire engaging structure is also simple.

The following preferred embodiments will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 2 , the embodiment of the present invention includes a housing 10 , a fastener 20 , and a spacer 30 . The housing 10 includes an upper surface 11 and a lower surface 12 . The fastener 20 is fixed to the upper surface 11 of the casing 10 , and the gasket 30 is fixed to the lower surface 12 of the casing 10 .

The upper surface 11 of the casing 10 is formed with an inwardly recessed engaging portion 111. The engaging portion 111 defines at least one guiding slot 13 extending through the casing 10 and at least one fixing slot 14 . And a first lens aperture 15, The guiding slot 13 and the fixing slot 14 are respectively disposed on two sides of the first lens hole 15; a fixing seat 16 extends along the edge of the first lens hole 15 on the lower surface 12 of the housing 10, An opening 17 is defined in the fixing seat 16 on a side of the fixed card slot 14 . In the embodiment, a fixing slot 14 and two guiding slots 13 are defined in the housing 10, and the fixing slot 14 is located on the line connecting the two guiding slots 13. The two guide card slots 13 are located on the same side of the first lens aperture 15.

As shown in FIG. 3, the fastener 20 includes a decorative surface 21 and a bottom surface 22; any pattern or appendage can be set on the decorative surface 21 according to the user's preference; and the bottom surface 22 of the fastener 20 is formed. a guiding hook 23 and a fixing hook 24 corresponding to the guiding slot 13 and the fixing slot 14, and the guiding hook 23 and the fixing hook 24 extend in the same direction on the bottom surface 22. In the present embodiment, two guiding hooks 23 and one fixing hook 24 are formed on the fastener 20, and the guiding hooks 23 and the fixing hooks 24 are respectively disposed at two ends of the fastening member 20, and The fixing hook 24 is located on the line connecting the two guiding hooks 23.

As shown in FIG. 4, the spacer 30 includes a fixing portion 31, a lens portion 32 and a connecting portion 33 for connecting the fixing portion 31 and the lens portion 31. At least one guiding protrusion 311 is disposed on the edge of the fixing portion 31. The guiding protrusion 311 extends perpendicularly outward from one side of the lens portion 32 by the fixing portion 31. The lens portion 32 defines a lens penetrating through the lens. a second lens hole 321 of the portion 32, and the second lens hole 321 corresponds to the first lens hole 15 on the housing 10, and a shielding plate 34 extends away from the connecting portion 33 on the lens portion 32. . The spacer 30 is made of an elastic material such as rubber or elastic plastic. In this embodiment The guiding protrusions 311 are two, and the two guiding protrusions 311 are located on the same side of the fixing portion 31.

As shown in FIG. 5, FIG. 6, and FIG. 7, in the assembly process, the spacer 30 is first assembled into the housing 10 from the lower surface 12 of the housing 10, so that the lens portion 32 of the spacer 30 is locked to the housing. In the fixing base 16 of the body 10, the shielding plate 34 protrudes from the opening 17 of the fixing base 16, and blocks the fixing slot 14 for blocking the electromagnetic field from the fixed card slot 14 to prevent the pair from being fixed. The image capturing lens of the lens portion 32 is disturbed; the fixing portion 31 of the spacer 30 is adjacent to the housing 10 at one end of the edge of the housing 10, and the guiding protrusion 311 is located at the guiding card slot of the housing. Just below the 13th.

Then, the fastener 20 is latched from the upper surface 11 of the casing 10 to the engaging portion 111. The fixing hook 24 of the fastener 20 is locked in the fixing slot 14 of the casing 10, and the fastener 20 is The guide hook 23 is locked in the guide slot 13 of the housing 10.

When the guide hook 23 is locked in the guide slot 13, the guide protrusion 311 on the spacer 30 abuts against the guide hook 23 in the direction in which the guide hook 23 is oriented, since the spacer 30 is fixed to the case The elastic deformation of the body 10 and the spacer 30 causes the guiding protrusion 311 to give the guiding hook 23 a force in the engaging direction, so that the locking between the fixing hook 24 and the housing 10 is closer, and Since the fastener 20 is interposed between the casing 10 and the gasket 30, the fastener 20 is not easily detached from the casing 10.

The engaging structure provided by the embodiment of the present invention is pressed against the guiding hook by the guiding protrusion, so that the locking between the guiding hook and the fixing hook and the guiding card slot and the fixing card slot is closer, thereby buckle The piece is not easily detached from the casing, and the entire engaging structure is also simple.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
