Abstract
The utility model pertains to structural improvement for electric actuators, in particular to housing of electric actuators, and is a moisture-proof and spray-proof structure for electric actuators, comprising housing of electric actuator, heating resistor inside the housing and an exhaust hole in lower part of the housing, characterized in that a dome is fixed at the exhaust hole in the lower part of the electric actuator, and by adding a dome at the exhaust hole in the lower part of the electric actuator, the utility model prevents backflow of water in lower part of the housing into the housing; moistures, penetration of which cannot be prevented by the dome, can be eliminated through original electric heating to ensure dryness inside the housing.
Description
Technical field
The utility model belongs to electric actuator, particularly the architecture advances of electric actuator housing.
Background technology
The moistureproof enclosure interior of common electric actuator all has a heating resistor, in case condensation vapor, causes the damage of the electric component of enclosure interior in enclosure interior.Housing originally has steam vent, and for anti-trickle enters, steam vent is in lower part of frame.
But because common housing 13 is a thin-wall construction all, see Fig. 1, common moisture steam vent 12 from the bottom under the effect of heating resistor 11 is discharged.But when housing top had a large amount of trickles to exist, lower housing portion just had a thick-layer water and exists, because vertical wall thickness in hole is less, a large amount of water is easy to flow into enclosure interior; And heating resistor power is often limited, for the energy-conservation and consideration burnout-proof enclosure interior, heating power ad infinitum can not be strengthened; Thereby such enclosure interior is very moist, still can cause the damage of the electric component of enclosure interior.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of anti-trickle structure of protection against the tide of electric actuator housing is provided.
The purpose of this utility model is achieved through the following technical solutions: the trickle structure is prevented in a kind of protection against the tide of electric actuator housing, comprise the electric actuator housing, the heating resistor of enclosure interior, the steam vent of lower housing portion is characterized in that: at the affixed kuppe in electric actuator lower housing portion steam vent place.
Compared with prior art, the beneficial effects of the utility model are: by increasing by a kuppe at electric actuator lower housing portion steam vent place, the water that makes lower housing portion can reverse inflow housing in, and only have only moisture to enter, and the moisture that enters we can thoroughly get rid of by original electric heating, and then guaranteed the housing inner drying.
Description of drawings
Fig. 1 is original electric actuator shell structure schematic diagram; Wherein, 11 heating resistors, 12 steam vents, 13 electric actuator housings.
Fig. 2 is the utility model electric actuator shell structure schematic diagram; Wherein, 1 kuppe, 2 air vent holes, 3 return ports, 4 steam vents, 5 electric actuator housings, 6 heating resistors, 7 angles
Fig. 3 is the vertical view of kuppe 1: 1 kuppe, 2 air vent holes, 3 return ports, 8 gussets
Embodiment
Structure of the present utility model is as shown in Figure 2: the trickle structure is prevented in a kind of protection against the tide of electric actuator housing, comprise electric actuator housing 5, the heating resistor 6 of enclosure interior, the steam vent 4 of lower housing portion is characterized in that: at the affixed kuppe 1 in electric actuator lower housing portion steam vent place.
Referring to Fig. 3, described kuppe is tubular or hollow structure square or sealing around other, is the hollow structure of tubular here.The kuppe outlet should form an angle 7 states, better to converge flowing of water.Affixed gusset 8 in kuppe, break-through pore 2, some return ports 3 on gusset.Kuppe 1 and housing can be one also can be kuppe as an assembling fittings.Housing should guarantee impermeability as far as possible except that steam vent.Housing also can become for component groups.
The effect of kuppe is: when trickle flows under the shell along outer wall from shell, to make water all poly-by kuppe to kuppe angle 7 places, both guaranteed water can be not reverse through air vent hole 2, return port 3, flow in the electric actuator housings 5 through steam vent 4, can not shut the exhaust passage of forming by steam vent 4, air vent hole 2, return port 3 simultaneously yet.
Affixed gusset 8 in kuppe, and the structure purpose of break-through pore 2, some return ports 3 is on gusset 8: steam can pass through, but stoped directly being splashed in the housing of water, less demanding occasion is affixed gusset 8 in kuppe, and on gusset 8 break-through pore 2, the structure of return port 3 can not have.
Claims (6)
1, the anti-trickle structure of a kind of protection against the tide of electric actuator housing comprises the electric actuator housing, the heating resistor of enclosure interior, and the steam vent of lower housing portion is characterized in that: at the affixed kuppe in the steam vent place of electric actuator lower housing portion.
2, the anti-trickle structure of the protection against the tide of electric actuator housing according to claim 1 is characterized in that: described kuppe can be an one or as an assembling fittings with housing.
3, the anti-trickle structure of the protection against the tide of electric actuator housing according to claim 1 is characterized in that: described kuppe is to have tubular or hollow structure square or sealing around other.
4, according to the anti-trickle structure of the protection against the tide of claim 1 or 3 described electric actuator housings, it is characterized in that: the outlet of kuppe is angle the best.
5, the anti-trickle structure of the protection against the tide of electric actuator housing according to claim 1 is characterized in that: be connected with gusset in kuppe, and be installed with venthole on gusset.
6, the anti-trickle structure of the protection against the tide of electric actuator housing according to claim 5 is characterized in that: be installed with some return ports on gusset.
