Abstract
A button device comprises a casing, a button and a switch component. The casing is provided with a button hole, and a clamping portion which surrounds the button hole in a circle and axially extends along the button hole is arranged on the inner side of the casing. The button is held in the button hole, one end of the button is provided with a stopping portion, and the stopping portion surrounds the outside of the button in a circle, stops the button from separating from the button hole and is provided with a matching portion. The matching portion surrounds in a circle and is clamped with the clamping portion. The switch component is held in the casing to press the button, so that the button deforms elastically and is abutted against the switch component to trigger a switch module. By arranging the clamping portion extending along the button hole axially on the casing and arranging the matching portion clamped with the clamping portion on the button, the button device is effectively waterproof and dustproof.

[embodiment]
Shown in Fig. 1~2, the pushbutton unit 100 of an embodiment comprises housing 110, button 120 and switch module 130.
Above-mentioned pushbutton unit can be applied on the light fixture, and in the time of preventing effectively that light fixture from using in rugged environment, rainwater or dust invade the inside of light fixture, causes the malfunctioning or short circuit of circuit.
Concrete, button 120 is cavity structure.Button 120 has an openend 122, and its end face relative with openend 122 forms and compresses structure 123.In the present embodiment, the material of button 120 is elastomeric material.The size of button 120 is less than the size of button hole 113, and button 120 elastic deformation can occur button hole 113 is interior.Housing 110 also comprises the spacing preiection 115 nested with holding section 114, and the height of spacing preiection 115 is greater than the height of holding section 114.Spacing preiection 115 can be nested with holding section 114 or be nested outward, in the present embodiment, and the spacing preiection 115 outer holding sections 114 that are nested in.The material of housing 110 is hard material.
Shown in Fig. 1~4, switch module 130 is the structure adaptive with the inner wall shape of housing 110, for example cuboid or cylinder.In the present embodiment, switch module 130 is the cuboid cavity.Switch module 130 has first end 131, second end 132 relative with first end 131.The end face of first end 131 is provided with through hole 133.The inside of switch module 130 is equipped with switch module 134, and switch module 134 has press key pole 1341.Press key pole 1341 is slender structure.In the present embodiment, press key pole 1341 is elongated cylinder.Press key pole 1341 parts are passed through hole 133 and are exposed.Switch module 130 is contained in the housing 110 by the opening of the lower surface 112 of housing 110.The end face of the first end 131 of switch module 130 compresses the openend 122 of button 120.Press key pole 1341 puts in the cavity of button 120 by openend 122.The face that compresses 123 by button 120 just can produce pressing press key pole 1341.The elastic deformation of button 120 produced pressing keys bar 1341 needed displacement stroke when utilization was pressed.
Further, for the seam crossing from press key pole 1341 such as anti-sealing, dust enters in the switch module 134, stop part is located at the outer peripheral edges of the openend 122 of button 120, and the shell of stop part and switch module 130 connects, with annular seal space of accommodating press key pole 1341 of common formation.
For auxiliary section 121 firm the holding with button 120 of the holding section 114 that makes housing 110, with the sealing between further raising housing 110 and the button 120, above-mentioned pushbutton unit also comprises pressure holding piece 140 and locking member 150.
In the present embodiment, pressure holding piece 140 is U-shaped structure, and its two ends are extended with flank (figure is mark not).The second end 132 parts of switch module 130 are contained in the pressure holding piece 140.The flank of pressure holding piece 140 is provided with two symmetrical through holes 141, and locking member 150 passes through hole 141 and is screwed in the housing 110, screws locking member 150 and just can form extruding force to switch module 130.Switch module 130 can be controlled by spacing preiection 115 in the displacement of housing 110 inside, just can change the displacement range of switch module 130 by the height that changes spacing preiection 115, thereby changes the extruding force of 130 pairs of buttons 120 of switch module.
Be appreciated that pressure holding piece 140 can replace to other shape, for example flat structure or lid type structure, but will guarantee switch module 130 is produced uniform extruding force.The number of through hole 141 can change, and is preferably symmetrical, and the degree of depth that locking member 150 screws in housing 110 is preferably consistent, can produce uniform extruding force like this, makes the good sealing of formation between button 120 and the housing 110.
Be appreciated that pressure holding piece 140 and locking member 150 can omit.Switch module 130 is cylinder.Inside at housing 110 arranges helicitic texture, at switch module 130 matching thread is set.Switch module 130 is screwed in the housing 110, just can produces the extruding to button 120.
The engaging mode between button 120 and the housing 110 that is appreciated that can have multiple.For example, auxiliary section 121 is along button hole 113 axially extended bulge-structures, and holding section 114 is along button hole 113 axially extended grooves.Perhaps, button 120 is set to the movable hermetically-sealed construction of energy, the snake fu jie structure of the elastic rubber layer that for example one deck is thin or Foldable near compressing face face 123 parts.Contact-making surface at button 120 and switch module 130 arranges the effect that O type circle further reaches sealing; Perhaps fill one deck airtight and watertight padding at the contact-making surface of button 120 and control box assembly 130 and realize the effect that seals.
The above embodiment has only expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
