Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
nullEmbodiment 1: as shown in Figure 1，A kind of switch of high security，Including switch body 102，Described switch body exterior is provided with housing 101，Described switch body bottom portion is provided with base 104，Opening 103 it is provided with below described housing，Cavity 105 it is provided with between described inner walls and described switch body outer wall，The width of described base is more than the width of described switch body，On described housing one side end face, it is provided with Buffer Unit in described switch body upper surface，Described Buffer Unit includes centring ring 106 and is sleeved on the rubber cushion 107 outside described centring ring，The height of described centring ring is less than the 1/2 of the thickness of described rubber cushion，Column 108 it is provided with in the middle part of described centring ring，The external diameter of described column is less than the internal diameter of described centring ring，It is provided with ball between the lower surface and described centring ring of described column，The relatively described inner walls in the upper surface of described column is unsettled，Described centring ring lower surface is fixedly connected on the upper surface of described switch body，Described rubber cushion upper surface is fitted on the lower surface of described housing，The lower surface of described rubber cushion is fitted on the upper surface of described switch body.
In the present embodiment, by arranging housing in switch body exterior, it can be avoided that drop or during external force collision, external force directly acts on switch body, when by External Force Acting, it is arranged on the rubber cushion between switch body upper surface and housing lower surface, active force can be played buffering effect, simultaneously, owing to rubber cushion has certain elasticity, during External Force Acting in the horizontal direction, rubber cushion is deformed, it is arranged on inside centring ring column under external force, produce the motion in horizontal direction, if now depositing the active force of in the vertical direction, column is under the effect of ball, produce displacement, simultaneously under the support of column, it can be avoided that the upper surface of the inwall direct collision switch body of housing.
Embodiment 2: the present embodiment is on the basis of embodiment 1, it is connected with each other between housing and base for convenience, in the present embodiment, preferably, the open side inwall of described housing is provided with draw-in groove 109, at described base towards being provided with the movable latch 110 that is plugged on inside described draw-in groove on the both sides end face of described draw-in groove, the thickness h of described movable latch is less than the thickness H of described draw-in groove.Movable latch is made to be plugged on inside draw-in groove, so that base two ends can be fixed in draw-in groove, base is made to be fixed up relative to housing, in the present embodiment, make draw-in groove be positioned at above the open side of shell, below draw-in groove, have certain surplus, so that this part enclosure structure is as supporting construction, can conveniently make below base unsettled, be favorably improved integrally-built radiating effect.
In the present embodiment, for masterpiece used time outside, base is enable to recover original position relative to draw-in groove, it is preferable that to be provided with back-moving spring 111 in described movable latch on the side end face inside described draw-in groove.Under the elastic acting force of back-moving spring, movable latch is enable to recover original position, it is to avoid to damage.
In order to playing sealing effectiveness between movable latch and draw-in groove, the space avoiding moisture to pass through between movable latch and draw-in groove enters case inside, do not affect its antidetonation cushioning effect simultaneously, in the present embodiment, preferably, it is respectively arranged with locating dowel 112 on two end faces in opposite directions inside described draw-in groove, locating dowel described in one side is 2 be arranged in parallel, seal gasket 113 it is provided with outside described locating dowel, described seal gasket one end is fitted on described draw-in groove inwall, the described seal gasket other end is fitted in described movable latch, described locating dowel is unsettled away from the movable latch that described draw-in groove inwall one end end face is relatively described.When housing is by applied external force, stressed shell produces mobile, and draw-in groove together moves under housing drives, and the seal gasket being arranged on inside is deformed under the effect of draw-in groove, active force can be played buffering effect, meanwhile, seal gasket uses rubber to make, and has the effect recovering shape under external force, when by External Force Acting, can cushioning effect power when external force disappears, resile shape, makes movable latch keep relative stability with draw-in groove.When external force is bigger, under external force, seal gasket is deformed, and locating dowel free end is fitted in movable latch, it is possible to avoid seal gasket excessive by External Force Acting, causes it impaired seriously, affects its sealing effectiveness.
In the present embodiment, after switch body longtime running, internal temperature is too high, it is provided with aeration-cooling structure, preferably, described housing both sides interior is provided with cavity, in described cavity, is provided with blower fan 114, the sidewall of described housing is provided with the passage 115 corresponding with described empty cavity position.Make, inside and outside passage connection cavity and housing, to start blower fan, make blower fan drive the air flowing of enclosure interior, it is achieved cooling.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
