Detailed Description

In order to further describe the technical means and effects adopted by the present utility model for achieving the intended purpose, the following detailed description of the specific embodiments of the present utility model is given with reference to the accompanying drawings and preferred embodiments.

Embodiment one:

referring to fig. 1 to 3, the present embodiment provides a snap-fit housing structure for a key switch, which includes a base 1 and an upper cover 2 disposed on the base 1, wherein a slot 3 is formed on one of the base 1 and the upper cover 2, at least one insertion arm 4 inserted into the slot 3 is formed on the other one, at least one slot 31 is formed on an inner wall of the slot 3, a clamping block 41 clamped into the slot 31 is formed on the insertion arm 4, and the upper cover 2 is snapped with the base 1 into a whole. Specifically, the slot 3 in this embodiment is formed on the base 1, and the arm 4 is formed on the upper cover 2. During installation, the inserting arm 4 is aligned to the slot 3 on the base 1 and inserted, so that the clamping block 41 on the upper cover 2 is finally clamped into the clamping groove 31 of the base 1, the upper cover 2 is buckled on the base 1, and buckling installation between the upper cover 2 and the base 1 is realized. Through setting up draw-in groove 31 on the inner wall of the inside slot 3 of base 1 to set up fixture block 41 on the arm 4 of inserting on upper cover 2, after upper cover 2 and base 1 lock, stable in structure, the lock structure is not seen from the outside, and the lock structure is not exposed promptly, and is whole pleasing to the eye, and the third dimension is stronger, and whole volume reduces.

In this embodiment, the clamping block 41 is formed on the outer sidewall of the insertion arm 4, so that the clamping block 41 can be better clamped into the clamping groove 31.

In order to enable the clamping block 41 to be smoothly clamped into the clamping groove 31, as shown in fig. 1 to 3, a first guiding inclined surface 411 is formed on the clamping block 41, and a second guiding inclined surface 311 matched with the first guiding inclined surface 411 is formed in the clamping groove 31. In the process that the inserting arm 4 is inserted into the slot 3, the clamping block 41 moves along with the slot 3, when the clamping block 41 encounters the clamping groove 31, the first guide inclined surface 411 on the clamping block 41 is matched with the second guide inclined surface 311 in the clamping groove 31 and provides a guide effect, so that the clamping block 41 can be clamped into the clamping groove 31 more smoothly and accurately, and the upper cover 2 and the base 1 are assembled more conveniently and rapidly.

Meanwhile, in order to enable the insertion arm 3 to be inserted into the insertion slot 3 more smoothly, as shown in fig. 3, a third guiding inclined surface 32 is formed on the outer side of the end of the insertion arm 3 in this embodiment. When the inserting arm 3 is inserted into the slot 3, the inserting arm 3 contacts with the port of the slot 3, and the third guiding inclined plane 32 provides guiding function, so that the inserting arm 3 can be inserted into the slot 3 more smoothly and conveniently.

For the number of the clamping grooves 31 and the clamping blocks 41, it may be determined according to specific products, and preferably, in this embodiment, the number of the clamping grooves 31 and the clamping blocks 41 is two, and the two clamping grooves 31 and the two clamping blocks 41 are respectively opposite to each other, as shown in fig. 2 and 3, so that the structure after installation is more stable.

Embodiment two:

the main difference between this embodiment and the first embodiment is that: as shown in fig. 4 to 6, the slot 3 'is formed on the upper cover 2, and the insertion arm 4' is formed on the base 1. Other structures are the same and are not described in detail herein.

During installation, the inserting arm 4 'is aligned with the slot 3' on the upper cover 2 and inserted, so that the clamping block 41 on the final base 1 is clamped into the clamping groove 31 of the upper cover 2, the upper cover 2 is buckled on the base 1, and buckling installation between the upper cover 2 and the base 1 is realized. Through setting up draw-in groove 31 on the inner wall of upper cover 2 inside slot 3 'to set up fixture block 41 on the arm 4' of inserting on base 1, after upper cover 2 and base 1 lock, stable in structure, the lock structure is not seen from the outside, and the lock structure is not exposed promptly, and is whole pleasing to the eye, and the third dimension is stronger, and whole volume reduces.

The foregoing is merely a preferred embodiment of the present utility model, and the technical scope of the present utility model is not limited to the above embodiments, so that other structures using the same or similar technical features as those of the above embodiments of the present utility model are all within the scope of the present utility model.
