Annular protrusion is formed between slot and fixation hole, key includes keycap, set on the water proof ring and trigger architecture of keycap surrounding, triggering
It is fixedly connected on the inside of one end of structure and keycap, the other end is contacted with key metal dome, and the medial surface of keycap is equipped with and convex annular
Mutually matched annular groove is played, annular protrusion engages in a ring groove, and water proof ring is fastened in capillary groove, and cover is pressed together on fixation
Shell upper surface is pressed on key in fixation hole.
A kind of preferred embodiment is that adjacent key passes through the water-proof strip connection being equipped with, and adjacent capillary groove is mutual by link slot
Connection, when key is pressed in fixation hole, water-proof strip is sealed in link slot.
A kind of preferred embodiment is keycap, and water proof ring is anti-and water-proof strip is an integral structure.
A kind of preferred embodiment is made of key by silica gel material.
In summary technical solution, the utility model has the beneficial effects that dustproof and waterproof effect is good, texture, appearance and operation
Good hand touch, at low cost, structure is simple.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
Art means, and being implemented in accordance with the contents of the specification, and in order to allow the above and other purpose, feature of the utility model

Specific embodiment
As shown in Figures 1 to 6, a kind of Waterproof push-button, including key 10, set casing 20, cover 30, pcb plate 40, Yi Jishe
Key metal dome 50 in 40 surface of pcb plate.Pcb plate 40 is set in set casing 20, the perforative fixed key 10 of set casing 20
Fixation hole 21, fixation hole 21 are surrounded by capillary groove 22, and annular protrusion 23, key are formed between capillary groove 22 and fixation hole 21
10 include keycap 11, set on the water proof ring 12 and trigger architecture 13 of 11 surrounding of keycap, one end of trigger architecture 13 and keycap 11
Inside is fixedly connected, and the other end is contacted with key metal dome 50, and the medial surface of keycap 11 is equipped with to cooperate with annular protrusion 23
Annular groove, annular protrusion 23 engages in a ring groove, and water proof ring 12 is fastened in capillary groove 22, and cover 30 is through there is through-hole
31, key 10 passes through through-hole 31, and cover 30 is pressed together on 20 upper surface of set casing and key 10 is pressed in fixation hole 21.Waterproof
Circle 12 is set in capillary groove 22, can prevent external dust or steam from entering in capillary groove 22, meanwhile, annular protrusion 23 to prevent
Sink 22 is isolated with fixation hole 21, further such that pcb plate 40 is isolated with external dust or steam, prevents external dust or steam
Into set casing 20.
Preferably, as shown in Figures 1 to 6, adjacent key 10 passes through the water-proof strip 15 being equipped with and connects, adjacent capillary groove 22
It is interconnected by link slot 24, when key 10 is pressed in fixation hole 21, water-proof strip 15 is sealed in link slot 24.
Preferably, as shown in fig. 6, keycap 11, water proof ring 12 is anti-and water-proof strip 15 is an integral structure.
In the utility model, key 10 is made of silica gel material.
As shown in Figures 1 to 6, key 10 includes keycap 11, water proof ring 12 and trigger architecture 13, and keycap 11 passes through elasticity
Deformation drives trigger architecture 13 and key metal dome 50 to trigger.The design of keycap 11 utilizes silica gel material softness in key-top
Characteristic guarantees that key 10 is normally pressed and bounced.
It is specific embodiment of the present utility model above, it is noted that for those skilled in the art
