Description

Quick detachable Anti-fall swell fixture
Technical field
The present invention relates to hanging or fix the screw of object in buildings decoration field on body of wall, more specifically, It is quick detachable Anti-fall swell fixture.
Background technology
Current swell fixture generally one carries the screw rod of inverted cone and is enclosed within screw rod and carries and can expand notch Expansion sleeve, the expanding screw nail of a diameter with expansion sleeve and length adaptation, Ran Houfang, when using, are first dug on body of wall Enter swell fixture, so that expansion sleeve is expanded by tightening the nut on screw rod, until swell fixture fastens in body of wall.A kind of in Disclosed on state's patent documentation " easily-detachable swell fixture ", its Publication No. CN2057612, in this technical scheme " easily-detachable swell fixture ", main include that an its one end carries inverted cone, another end is threaded the screw rod of section, one On screw rod and thereon with the expansion sleeve being available for the notch that its deformation swells, one is contained in screw flight section and energy kink Make the nut that expansion sleeve dilates in its rotation, and be located at the packing ring between expansion sleeve and nut, it is characterized in that:Its rounding With the projection that can embed in notch on the end outer wall of cone, the quantity of projection is equal with the notch quantity on expansion sleeve, and spiral shell The length of the thread segment of bar is more than the length of inverted cone and the length sum of notch.Solve existing swell fixture to be difficult from body of wall On the problem pulled down, and also there is this dismounting can reuse without detriment to body of wall, swell fixture.But because this " can conveniently fill The swell fixture torn open " exists after screw is got rusty with nut, when nut and screw rod cause nut cannot dismantle after rotating simultaneously, When expansion sleeve increased to maximum and projection be also not embedded into notch just cannot be so that screw will not rotate, expansion sleeve is also possible to simultaneously Rotation simultaneously is so that nut cannot be dismantled, and the screw left after dismantling can drop the defect hurted sb.'s feelings.
Content of the invention
The present invention specifically addresses nut and screw rotate back nut and cannot dismantle in prior art simultaneously, and lose after dismantling The screw staying can drop the defect hurted sb.'s feelings.Aim to provide one kind and be readily disassembled nut, be difficult safely to drop, simple to operate is readily removable Unload Anti-fall swell fixture.
In order to solve above-mentioned technical problem, the present invention adopts following technical proposals:Quick detachable Anti-fall expanding screw Nail, including screw rod, expansion sleeve, nut and pad, one end of described screw rod is provided with screw thread, and the other end is provided with locating shaft, locating shaft It is provided with the location hole of insertion, positioning in the hole is fitted with alignment pin, and the cylindrical centre of alignment pin is provided with the little ladder of outer imperial palace in the middle of axially Shape groove, is provided with pre- off-axis in the middle of dovetail groove, screw rod longitudinal center is provided with the impact rod aperture being mutually perpendicular to insertion with location hole, impact It is provided with striking rod, striking rod one end is provided with the conehead with dovetail groove adaptation, the impact rod aperture at described screw flight end in rod aperture It is provided with closing in, the two ends length of alignment pin is identical with locating shaft outside diameter, can enter expanding screw nail to greatest extent Hole wall so that screw rod can not rotate after blocking, alignment pin and striking rod are loaded after screw rod, then are formed by punching press after and impact The closing at rod aperture end, so that locating shaft and striking rod are constrained on location hole and striking rod in the hole respectively without dropping out, works as hammer Hit striking rod protruding part when, striking rod be pressed down against alignment pin so that alignment pin prejudge axle fracture separately after, alignment pin End enter the hole wall of expanding screw nail, screw rod is securely fixed in swell fixture in the hole, so rotation described nut when Would not cannot turn on nut because screw rod rotates simultaneously so that nut is highly susceptible to removing, after fixation is removed, lose The swell fixture staying on the wall does not fall out yet hurts sb.'s feelings, and simple to operate.
Preferably, the conehead of described striking rod fits in dovetail groove, it is conformed with the middle of the other end of striking rod, institute Not above screw flight end or flush, the conehead of striking rod serves tiltedly embedding effect to the high point stating projection, when hitting Make bar when moving downward, so that alignment pin is squeezed moving out, the bump of striking rod makes stress point concentrate on to hit Beat the center of bar.
Preferably, the two ends of described alignment pin are equipped with taper plunger, expanding screw nail can be more easily entered Hole wall is so that screw rod can not rotate after blocking.
Preferably, a diameter of 0.5 millimeter of the middle pre- off-axis of described alignment pin to 1.5 millimeters, after test of many times, In the range of this, pre- off-axis is easier to rupture, and the setting of pre- off-axis can be made of one with alignment pin it is also possible to determine Again pre- off-axis is loaded after centre-drilling hole at the pre- off-axis of position pin.
Preferably, the external adapter of described striking rod has the auxiliary rod for impact, so can need to impact When very convenient naturally it is also possible to can be entered with other impact rod aperture metal bar substitute.
Due to adopting technique scheme, the beneficial effect of the quick detachable Anti-fall swell fixture that the present invention provides is:1. Nut is readily disassembled;2. being difficult drops hurts sb.'s feelings;3. simple to operate.
