Therefore, the bottom plate of the switch socket has the advantages that the screws can be prefixed and the bottom plate is simple to manufacture.
Description
[technical field]
The utility model relates to a kind of combined socket and switch base plate, particularly relates to a kind of surface mounted switch socket base plate.
[background technology]
Traditional combined socket and switch base plate need be by screw on wall.General combined socket and switch base plate is provided with screw mounting hole, during fixing above-mentioned combined socket and switch base plate, need earlier screw to be penetrated screw mounting hole, fall down to prevent screw or combined socket and switch base plate with hand steered firmly screw then, beat screw again to be fixed on the wall.
In order to accelerate installation rate, the design of predetermined fixed screw is arranged at present.A kind of design is to lay the screw claw around screw mounting hole, by earlier with screw in the screw claw, and then beat screw.Also having a kind of design is to lay elasticity card muscle on the hole wall of screw mounting hole, is fixed by elasticity card muscle earlier when screw inserts, and then beats screw.
Above-mentioned claw and elasticity card muscle mostly are strip, rupture easily, therefore manufactured materials are had higher requirements.And the above-mentioned structure that pre-fixes needs to lay a plurality of claws or a plurality of elasticity card muscle could guarantee that screw can be stuck, and reaches the effect that pre-fixes.
Therefore, this type of combined socket and switch base plate pre-fixes the structure fabrication complexity.
[utility model content]
Based on this, be necessary to provide a kind of and can pre-fix screw and make simple combined socket and switch base plate.
A kind of combined socket and switch base plate, comprise substrate, this substrate by screw on supporter, this substrate has the contact-making surface that contacts with this supporter and reaches and the opposing installed surface of this contact-making surface, offer screw mounting hole on this substrate, this screw mounting hole runs through this contact-making surface and this installed surface, and this combined socket and switch base plate comprises that also the screw on the hole wall that is convexly set in this screw mounting hole pre-fixes part, and it is concordant with this installed surface away from an end of this contact-making surface that this screw pre-fixes part.
Because it is concordant with this installed surface away from an end of this contact-making surface that this screw pre-fixes part, so when mounted, can beat this screw and be close to this installed surface until the nut of this screw, makes the nail post of this screw can farthest follow closely into wall always.Because this screw pre-fixes part and is located in this screw mounting hole, thus make easily, and this pre-fixes structure difficult drop-off and fracture when this combined socket and switch base plate of extraneous object collision.Simultaneously, the shape that this screw pre-fixes part can be thin slice, cylinder or other even irregular shape, and this screw pre-fixes the quantity of part can be for one or more.Therefore, this combined socket and switch base plate can pre-fix screw and make simple.
Further, it is a plurality of elastic sheets that this screw pre-fixes part, this elastic sheet is circumferentially spaced apart this this screw mounting hole of hole wall upper edge, and the end away from this hole wall of this elastic sheet surrounds circular through hole, and the diameter of this through hole is smaller or equal to the diameter of the double-screw bolt of this screw.
Because the diameter of this circular hole is smaller or equal to the diameter of the double-screw bolt of this screw, this screw can be stuck when inserting.Because this projection is an elastic sheet, when being entered wall so this screw beats, this elastic sheet is unlikely to stop that the nail of this screw advances.Because this elastic sheet is in the same plane and spaced apart, so this screw can be snapped on the residing plane of this elastic sheet when inserting, stressedly evenly be difficult for crookedly, guaranteed the effect that pre-fixes.
Further, it is an annular flake coaxial with this screw mounting hole that this screw pre-fixes part, and the internal diameter of this annular flake is smaller or equal to the diameter of the double-screw bolt of this screw.
Because the diameter of this circular hole is smaller or equal to the diameter of the double-screw bolt of this screw, this screw can be blocked by this elastic sheet when inserting.Because this elastic sheet has only one, so make simple.
Further, it is an elastic sheet of sealing this screw mounting hole that this screw pre-fixes part, and this elastic sheet is made by the material that is easily punctured by this screw, and this elastic sheet is pierced with the insertion of this screw, breaks and is out of shape, thereby block this screw.
Because this elastic sheet easily punctures by this screw, so also can not hinder this screw and insert this screw mounting hole even this thin slice is sealed this screw mounting hole.After this screw punctured this elastic sheet, this elastic sheet split and deforms, and can block this screw, can not hinder again this screw continue hammer into.
Further, it is a columned projection that this screw pre-fixes part, and the through hole that this projection and this hole wall surround can block the double-screw bolt of this screw, and this projection is made by elastomeric material.
Further, it is a plurality of projectioies that this screw pre-fixes part, these a plurality of projectioies are circumferentially spaced apart this this screw mounting hole of hole wall upper edge, these a plurality of projectioies are the cylindrical bump that extends along the radial direction of this screw mounting hole, these a plurality of projectioies surround a circular hole away from an end of this hole wall, the diameter of this circular hole is smaller or equal to the diameter of the double-screw bolt of this screw, and these a plurality of projectioies are made by elastomeric material.
Because this projection is made by elastomeric material, therefore when this screw inserted, this projection can be pushed this screw, thereby with this screw; When continuing to beat this screw, can not hinder hammering into of this screw.
Further, this combined socket and switch base plate also is provided with the screw erection column, and this screw erection column is located on this substrate, and this installed surface is the end face of this screw erection column away from this contact-making surface, and this screw mounting hole is opened in this screw erection column.
When this combined socket and switch base plate was thin, the axial length of this screw mounting hole was less, the poor effect that pre-fixes.The effect of this screw erection column is to increase the axial length of this screw mounting hole, guarantees the effect that pre-fixes.
Further, this screw erection column is the cylinder that extends along perpendicular to the direction of this contact-making surface.
The vertical design of above-mentioned screw erection column meets general screw custom is installed, and vertical installation can better be fixed on this combined socket and switch base plate on this supporter.
Further, this screw mounting hole is the truncated cone-shaped through hole, and the diameter of an end of close this installed surface of this screw mounting hole is less than the diameter of an end of close this contact-making surface.
Because this screw mounting hole is gradually big to this end diameter near supporter at the end away from this supporter, even should hammer into the position of this screw when therefore installing on this screw and this supporter does not aim at, the screw that also can tilt is slightly regulated handled easily.
