Abstract
The invention relates to a inpact type expanding fastener that belongs to fastener technology field. The inner end part of the hole-matched stick is set at least two expanding lamella. The axial direction of outside of the hole-matched stick is set a tack hole that extends to the opening place of the expanding lamella and has a knock-in tack. The diameter of the knock-in tack is bigger than the diameter of the opening place or the width of the gap, and the length is longer than that from outside of the holes matched stick to the opening place. The advantage of the invention is that it only needs be knocked to install and is easy to operate and use. It has a broad market prospect.
Description
Technical field
The invention belongs to the technical field of fastening of inner clamping type friction grip, be specifically related to a kind of setscrew.
Background technique
Setscrew needs a large amount of a kind of clamp structures that use when being the device installation.When installing and using, the formula of tightening setscrew in the past needs fastening nut, operation inconvenience; Sometimes also need to beat screw rod,, promptly cause and scrap in case beat improperly; And general thermal expansion of this kind setscrew and expansive force are less, and the mounting technique level requires high, and be fixing sometimes not firm, slippage easily, and sometimes even intermediate bar can be extracted out, soundness and Security are relatively poor; Its processing technology is relatively poor, and is time-consuming, and consumptive material is many, and waste is big.
Summary of the invention
The purpose of this invention is to provide a kind of impact type expansion fastener, only need to impact when it is installed and used to get final product, have operation and use extremely convenient, expansive force is big, fixing reliable, be difficult for slippage, advantage such as of many uses.The convenience that can be widely used in setscrew and multiple device is fixed.
Main technical schemes of the present invention is: a kind of impact type expansion fastener, comprise hole-matching-rod, the inner end portion that it is characterized in that hole-matching-rod is provided with more than 2 and (contains 2, or 3,4,5,6 etc.) expanding petal, the hole is followed closely in being axially arranged with of the exterior edge face of hole-matching-rod, and the nail hole extends the expanding of expanding petal; And knock-in tack is arranged, and the bar of knock-in tack footpath is greater than the diameter in the expanding hole of expanding petal or the width in slit, the length of knock-in tack greater than from the exterior edge face of hole-matching-rod to the length of expanding petal the expanding.
Above-mentioned expanding petal is good with 4, and axial and mutually perpendicular otch is constituted by twice for it, and the axis in nail hole is by the axis of hole-matching-rod.
As follow closely the axis of the axis runout hole-matching-rod in hole, but the nail hole is aimed at expanding petal the expanding and also can.
For making anti-slip better effects if, above-mentioned expanding petal outside can be provided with the retaining structure.
For being applicable to multiple occasion and purposes, above-mentioned hole-matching-rod available metal or plastics etc. are made.Metal can be used middle low carbon steel, stainless steel or Cuprum alloy, aluminum alloy or magnesium alloy etc.
For making anti-slip better effects if, can be provided with the retaining structure on the nail bar of above-mentioned knock-in tack and/or on the wall in nail hole.
Above-mentioned retaining structure can be hangnail, reticulate pattern, projection, screw thread, burr or adhesive coating etc.
For being applicable to multiple occasion and purposes, the outer end portion of above-mentioned hole-matching-rod can be provided with the dedicated function device.
Above-mentioned dedicated function device architecture can be: outer end portion is provided with screw thread; Or have nut on the outer end portion screw thread; Or integral type or the split type hook of dedicated function device architecture, pipe clamp, towel peg etc.
Only need when the present invention installs and uses simply to impact to get final product, have operation and easy to use, expansive force big, fixing reliable, be difficult for slippage,, be suitable for advantages such as attractive in appearance, material-saving and purposes are wide, the convenience that can be widely used in setscrew and multiple device is fixed.Be a kind of very convenient and reliable being suitable for and multipurpose fastening piece attractive in appearance, vast market prospect is arranged.
Be described further below in conjunction with embodiment and symbol figure, but not as a limitation of the invention.

Fig. 4 is the sectional drawing of B-B among Fig. 3.
Embodiment
Referring to Fig. 1, Fig. 2, the inner end part of hole-matching-rod 2 is provided with 4 expanding petals 23, and it is made of two axial mutually perpendicular otch 24; Hole 22 is followed closely in being axially arranged with of the exterior edge face of hole-matching-rod 2, and the axis in nail hole 22 is followed closely the expanding that hole 22 extends expanding petal 23 by the axis of hole-matching-rod 2; And knock-in tack 1 is arranged, and the bar of knock-in tack 1 footpath is greater than the diameter in the expanding hole of expanding petal 23 or the width in slit, the length of knock-in tack 1 greater than from the exterior edge face of hole-matching-rod 2 to the length of expanding petal 23 the expanding, or equal the entire length of hole-matching-rod 2; Expanding petal 23 outsides are provided with hangnail retaining structure 25, and the retaining structure on the nail bar of knock-in tack 1 is the reticulate pattern (not shown); The outer end portion of hole-matching-rod 2 is provided with screw thread 21, can transfer its length according to needs, has nut 3 on the screw thread 21.For example, the straight warp of hole-matching-rod 2 is 12mm, and length is 80mm; The straight warp in nail hole 22 is 4.2mm, and length is 55mm; The width of otch 24 is 1mm, and length is 25mm; The straight warp of knock-in tack 1 is 4mm, and length is 80mm.Can be made into the different size model.Can be placed on the position that needs during use, setscrew be put into holed, will follow closely 1 usefulness hammer and squeeze into and get final product.Can be according to the expansive force test formula design thermal expansion and the expansive force of material and requirement.Setscrew is made with stainless steel.It is easy for operation, expansive force is big, it is reliable to fix, be difficult for slippage, and is suitable for attractive in appearance, non-corrosive, and is of many uses.
Referring to Fig. 3, Fig. 4, the outer end portion of hole-matching-rod 5 is fixed with dedicated function device wall hanger (or conduit saddle etc.) 51, is integral type; Expanding petal 6 is 3 lobes; 4 is knock-in tack, and outward appearance is succinctly attractive in appearance.Only need simply impact nail 1 during installation gets final product.
