Abstract
The utility model relates to a fastener used in brittle material thin plates. The fastener comprises a rivet rod, the rivet rod is sleeved by a sleeve whose top is provided with a cap joint, the inner diameter of the sleeve is less than the rivet rod joint, the lower part of the sleeve is an expansion tablet that inclines to the medial of the sleeve and the expansion tablet is enclosed to a systolic port. The lower end of the expansion tablet is provided with an outward process, the expansion tablet is provided with friction stria at the systolic port, the distance between the systolic port and the part whose diameter is less than the rivet rod joint is adapted to the length from the bottom to the biggest part of the rivet rod joint. The utility model has the advantages of simple structure, convenient installation and operation and anti-seismic performance, has no stress to the hole bottom plate, and is specially suitable for thin plates.
Description
The utility model relates to a kind of fastening piece that is applied to the brittle material thin plate.
Post-cut is the brittle material thin plate fixedly, the crab-bolt of employing is arranged at present as fastening piece, although this fastening piece has its characteristics, the installation between fastening piece and sheet material and sheet material and its accompanying thing is comparatively loaded down with trivial details.
The purpose of this utility model is to provide a kind of installation fastening piece more easily.
For achieving the above object, the utility model is by the following technical solutions: it comprises rivet rod, be with the top on the rivet rod and be provided with the sleeve of cap head, sleeve diameter is less than the rivet rod head, the bottom of sleeve is for surrounding a contraction mouth to inboard expansible of tilting of sleeve and by expansible, expansible underpart has outside outstanding, and expansible is provided with the friction line at the contraction mouth place, and contraction mouth is suitable to the length of its biggest place with rivet rod head root less than the distance at rivet rod head place to aforementioned internal diameter.
The utility model also can adopt following further technological scheme simultaneously:
Also be provided with suspension member on the cap head.
Expansible has the lead angle that the rivet rod head enters this contraction mouth below contraction mouth.
The outside of described sleeve is provided with elasticity packing layer, and the upper end of elasticity packing layer has the annular solid that is shim-like.
Flexible packing cover is overlapped in the outside of described sleeve, and the upper end of elasticity packing cover has the annular solid that is shim-like.
Because adopt above technological scheme, the utility model structure is extremely simple, the installation of fastening piece and sheet material only need be adopted common riveting operation, and is extremely convenient, can finish at engineering site.Adopt structure of the present utility model also to be convenient on the cap head, suspension member is set simultaneously, so not only make things convenient for the installation between sheet material and its accompanying thing, can save installation cost simultaneously.Adopt elasticity packing layer or structure, can also further increase anti-seismic performance.Installation of the present utility model is unstressed to the hole bottom plate, especially is fit to be used in thin type sheet material.
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1 is the utility model embodiment 1 a sectional view.
Fig. 2 is expansion back sectional view of the present utility model.
Fig. 3 is the utility model embodiment 2 a sectional view.
Embodiment 1
With reference to accompanying drawing 1.The utility model comprises rivet rod 1, be with the top on the rivet rod and be provided with the sleeve 3 of cap head 2, sleeve diameter is less than rivet rod head 4, the bottom of sleeve is for surrounding a contraction mouth 6 to inboard expansible 5 of tilting of sleeve and by expansible, expansible underpart has outside outstanding 7, expansible is provided with friction line 8 at the contraction mouth place, contraction mouth is suitable to the length of its biggest place with rivet rod head root less than the distance at rivet rod head place to aforementioned internal diameter.The friction line can also can be other form for screw thread.
But the outer side of described sleeve is overlapped flexible packing cover 9, and the upper end of elasticity packing cover has the annular solid 11 that is shim-like.
Expansible can have the lead angle 10 that the rivet rod head enters this contraction mouth below contraction mouth.
With reference to Fig. 2.When the installation of fastening piece and sheet material, earlier elasticity packing cover 9 is inserted the pre-drilled recessed hole of band side, bottom in the sheet material, again the utility model remaining part to be inserted, drawing reference numeral 12 is a hanging part.Adopt the method for riveted fixing then, rivet rod is outwards pulled out, make rivet rod head 4 pass contraction mouth, and with expansible expansion, anchor pole can't rise when the rivet rod head runs into internal diameter less than rivet rod head place, the fracture of rivet rod top is abandoned, at this moment, the biggest place of rivet rod head is in the contraction mouth place, and be expanded to maximum value with expansible, above-mentioned outstanding 7 to enter the side in hole recessed, because friction line 8 and internal diameter cooperatively interacting less than rivet rod head place, remaining rivet rod can't be up and down, and finish the installation of fastening piece and sheet material.
Embodiment 2
With reference to accompanying drawing 3, this figure installs back schematic representation of the present utility model for finishing fastening piece and sheet material.Also be provided with suspension member 13 on the present embodiment frieze rail, the outside of described sleeve can be provided with elasticity packing layer 14, and the upper end of elasticity packing layer has the annular solid 15 that is shim-like.Utilize suspension member 13 directly sheet material to be installed on its accompanying thing, and need not establish the hanging part 12 among the embodiment 1 more in addition.
Claims (5)
1, a kind of fastening piece, it is characterized in that it comprises rivet rod, be with the top on the rivet rod and be provided with the sleeve of cap head, sleeve diameter is less than the rivet rod head, the bottom of sleeve is for surrounding a contraction mouth to inboard expansible of tilting of sleeve and by expansible, expansible underpart has outside outstanding, and expansible is provided with the friction line at the contraction mouth place, and contraction mouth is suitable to the length of its biggest place with rivet rod head root less than the distance at rivet rod head place to aforementioned internal diameter.
2, a kind of fastening piece as claimed in claim 1 is characterized in that also being provided with on the cap head suspension member.
3, a kind of fastening piece as claimed in claim 1 is characterized in that expansible has the lead angle that the rivet rod head enters this contraction mouth below contraction mouth.
