Abstract
The utility model discloses a two direction switch's casing, including drain pan and upper cover, the drain pan is provided with the upper shed, and the upper cover is provided with the under shed, and the edge of under shed is provided with outer flange and interior flange, forms the recess between outer flange and the interior flange, is provided with the seal ring aequilate with the recess in the recess, is provided with the lug that lies in the recess and be used for fixed seal ring on the interior flange, and the distance between lug and the outer flange equals the width at upper shed edge. The beneficial effect of the utility model: distance between lug and the outer flange equals the width at upper shed edge to the setting of lug make the lug avoid in the effect of playing the fixed seal packing ring because resulting in the upper shed of drain pan the circumstances complete and the seal ring butt to take place. Because the effect of lug, can't fall out the recess of upper cover after the seal ring installation easily to it is troublesome when avoiding installing.
Description
Technical field
This utility model relates to switch case, particularly to the housing of a kind of two-direction switch.
Background technology
The Chinese patent of Publication No. 201117467 discloses the shell of a kind of two-direction switch, and the shell of this two-direction switch, by arranging seal washer between drain pan and upper cover, improves the water resistance of switch housing, increases the safety in utilization of two-direction switch.
But, when two-direction switch breaks down and keeps in repair, need to separate drain pan with upper cover.And drain pan when separating with upper cover seal washer easily drop out from the groove of upper cover, cause needing again to be bumped in groove by seal washer, cause installation inconvenience, have much room for improvement.
Utility model content
The purpose of this utility model is to provide the housing of the two-direction switch of a kind of bonding strength strengthening seal washer and upper cover.
Above-mentioned technical purpose of the present utility model has the technical scheme that
A kind of housing of two-direction switch, including drain pan and upper cover, described drain pan is provided with upper shed, described upper cover is provided with under shed, the edge of described under shed is provided with outer flange and interior flange, forms groove, be provided with the seal washer wide with groove in described groove between described outer flange and interior flange, being provided with the projection being positioned at groove for fixing seal packing ring on described interior flange, the distance between described projection and outer flange is equal to the width at upper shed edge.
By using technique scheme, distance between projection and outer flange is equal to the width at upper shed edge, so that projection is avoided because the situation that the setting of projection causes the upper shed of drain pan to abut with seal washer completely occurs while playing the effect of fixing seal packing ring.Due to the effect of projection, the groove of upper cover cannot be dropped out after seal washer installation easily, thus bother when avoiding installing.
This utility model is further arranged to: the distance between described projection and the bottom land of groove is equal to the thickness of seal washer.
By using technique scheme, owing to the distance between projection and the bottom land of groove is equal with the thickness of seal washer such that it is able to strengthen the projection sealing function to seal washer.
This utility model is further arranged to: described projection has multiple along the length direction spaced set of interior flange.
By using technique scheme, if the length direction of interior flange is respectively provided with projection, then cause difficulty during the first installation of seal washer bigger.And multiple projection is set and can reduce the first installation difficulty of seal washer on the premise of ensureing the fixation to seal washer.
This utility model is further arranged to: the length of described interior flange is less than the length under shed edge.
By using technique scheme, the length of interior flange is less than the edge length of under shed, thus seal washer is exerted a force by the edge being convenient for people to be not provided with interior flange under shed, is taken out by seal washer from groove.
This utility model is further arranged to: the height of described outer flange is higher than the height of interior flange.
By using technique scheme, the height of outer flange is higher than interior flange, and the height of interior flange is higher than seal washer, and the height of outer flange is also above seal washer.Thus time outer flange can play more preferable protective effect.
This utility model is further arranged to: described upper cover includes the overhead gage that four pieces of head and the tail are sequentially connected with, one end of four pieces of described overhead gages is respectively connected with same upper sealing plate, the other end surrounds under shed, and four pieces of described overhead gages gradually converge toward upper sealing plate direction under shed.
By using technique scheme, four pieces of overhead gages gradually converge toward upper sealing plate direction under shed, and the palm of human body is also gradually to converge toward tiger's jaw direction from finger tip, and both are consistent, so that people are more comfortable when holding with a hand housing.
In sum, this utility model has the advantages that
Distance between projection and outer flange is equal to the width at upper shed edge, so that projection is avoided because the situation that the setting of projection causes the upper shed of drain pan to abut with seal washer completely occurs while playing the effect of fixing seal packing ring.Due to the effect of projection, the groove of upper cover cannot be dropped out after seal washer installation easily, thus bother when avoiding installing.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
With reference to Fig. 1,2 and 3, the housing of a kind of two-direction switch, including drain pan 1 and upper cover 2.Drain pan 1 includes the lower baffle plate 11 that four pieces of head and the tail are sequentially connected with.One end of four pieces of lower baffle plates 11 is respectively connected with same base plate 12, and the other end surrounds upper shed.Upper cover 2 includes the overhead gage 21 that four pieces of head and the tail are sequentially connected with.One end of four pieces of overhead gages 21 is respectively connected with same upper sealing plate 22, and the other end surrounds under shed.Four pieces of overhead gages 21 gradually converge toward upper sealing plate 22 direction under shed.
With reference to Fig. 1,2 and 3, the edge of under shed is provided with outer flange 3 and interior flange 4, between outer flange 3 and interior flange 4 formed groove.The seal washer 5 wide with groove it is provided with in groove.Being provided with the projection 6 being positioned at groove on interior flange 4, the distance between projection 6 and outer flange 3 is equal to the width at upper shed edge.Distance between projection 6 and the bottom land of groove is equal to the thickness of seal washer 5.Projection 6 has multiple along the length direction spaced set of interior flange 4.Preferably, projection 6 is provided with 2.
Distance between projection 6 and outer flange 3 is equal to the width at upper shed edge, so that projection 6 is avoided because the situation that the setting of projection 6 causes the upper shed of drain pan 1 to abut with seal washer 5 completely occurs while playing the effect of fixing seal packing ring 5.Due to the effect of projection 6, the groove of upper cover 2 cannot be dropped out after seal washer 5 installation easily, thus bother when avoiding installing.
