Abstract
The utility model relates to a socket switch. An installation screw fixation structure comprises an installation hole formed in the socket switch, wherein at least two cards are arranged on the hole wall of the installation hole, and the cards are distributed along the peripheral direction of the installation hole. The utility model provides an installation screw fixation structure capable of fixing an installation screw in the installation hole, which solves the problem of inconvenient installation for the socket switch.
Description
Technical field
The utility model relates to socket switch, relates in particular to a kind of fixed installation screw structural.
Background technology
Installing hole on the existing wall socket switch all be designed to bigger than screw is installed, when being installed to socket switch on the wall by install screw pass the installing hole rear thread be connected on the wall or pass installing hole by steel nail after nail on wall.
China Patent No. be ZL2012205518600, Granted publication day are March 20 in 2013 day, be called installing hole on the socket switch that discloses existing structure in the patent document of " combined socket and switch ".
When the mounting receptacle switch is to the wall, need a hand to take instrument, the hand steered firmly socket switch of another, the words that people installs can not free hand to fixedly mount screw and existing installing hole can not be fixed screw is installed, have only this moment two people of employing to install, there is the problem that inconvenience is installed in therefore existing socket switch.
The utility model content
The utility model provides a kind of fixed installation screw structural that the installation screw can be fixed in the installing hole, has solved socket switch inconvenient problem is installed.
Above technical problem solves by following technical proposal: a kind of fixed installation screw structural, comprise the installing hole that is arranged on the socket switch, and the hole wall of described installing hole is provided with at least two elastic cards, and described card is along the circumferential distribution of described installing hole.During the mounting receptacle switch, hand steered firmly socket switch, an another hand rotate and screw are installed in installing hole earlier, card produces strain and construction bolt is fixed, and vacates that hand that rotates the installation screw then and goes to take instrument, by instrument screw thread will be installed and be connected on the wall.If bolt is less the free end of card be stuck in if diameter that screw is fixed on the interior bolt of installing hole will be installed more greatly in the screw thread that screw is installed then
As preferably, the free-ended thickness of described card is less than the screw thread ditch width of construction bolt." screw thread ditch width " refers to the width of the groove that forms between the screw thread on the construction bolt.Can be in the less deficiency of screw so that during the card distortion, the free end by card is stuck in the screw thread to be fixed construction bolt.
As preferably, the free end of described card is positioned on the same face of cylinder.Convenient during making.
As preferably, the free end of described card is provided with chamfering.Narrower and the narrow outer end of threaded inner end is wide because of the width of the screw thread of fixed screw, it is dark and screw is installed is not easy to produce and rocks that this design makes that card gos deep into the degree of depth of screw thread.
As preferably, described card has four, and described card circumferentially evenly distributes along described installing hole.Stationarity when fixing the dress screw is good.
As preferably, the outer end of described installing hole is provided with chamfering.To install when screw is inserted in the installing hole and make things convenient for.When " installing hole outer end " referred to that socket switch is fixed on the wall, installing hole was away from an end of wall.
As preferably, described card apart from the distance of installing hole outer end less than the distance of described card apart from installing hole the inner.Can reduce the weight difference that screw is positioned at the card inside part and is positioned at the card Outboard Sections is installed, little to the bending power of card when screw being installed also not being screwed into wall, make card intensity hour, this bending power can not make the card bending and lose the fixation of screw is installed.
The utlity model has following advantage: owing to can be fixed in the installing hole screw is installed, improved the convenience when socket switch is installed; Novel structure.
Description of drawings
Fig. 1 is the schematic diagram that carries out projection along the depth direction of installing hole of the present utility model.
Fig. 2 is A-A cross-sectional schematic of Fig. 1.
Fig. 3 for the utility model to screw the use view fixedly the time.
Among the figure: socket switch 1, installing hole 2, installing hole portion chamfering 21, card 3, card service chamfering 31, install screw 7, wall 8, card apart from the distance L 1 of installing hole outer end, card apart from the free-ended thickness L3 of distance L 2, the card of installing hole the inner, screw thread ditch width L4.
Embodiment
Be further described below in conjunction with accompanying drawing and the utility model of embodiment.
Embodiment one, and referring to Fig. 1, a kind of fixed installation screw structural comprises the installing hole 2 that is arranged on the socket switch 1.The outer end of installing hole 21 is provided with installing hole portion chamfering 21.
The hole wall of installing hole 2 is provided with four elastic cards 3.Card 3 circumferentially evenly distributes along installing hole 2.The free end of card 3 is provided with card service chamfering 31.The free-ended end face of 4 cards 3 is positioned on the same face of cylinder.
Referring to Fig. 2, card apart from the distance L 1 of installing hole outer end less than the distance L 2 of card apart from installing hole the inner.
Referring to Fig. 3, the free-ended thickness L3 of card is less than the screw thread ditch width L4 of construction bolt 7.During use, then rotate earlier and screw 7 is installed in installing hole 2, if less then free end card 3 of construction bolt 7 this moment is inserted in the screw thread that screw 7 is installed, make that screw 7 is installed to be fixed in the installing hole 2 by card 3; If construction bolt 7 more greatly card 3 strains and resilient clamp is firmly installed screw 7 be fixed in the installing hole 2 and screw 7 will be installed.Buttressing on the other hand socket switch 1, another hand then holds instrument and screw 7 will be installed be threaded onto on the wall 8.Certainly screw thread 7 being installed also can be steel nail.
