Abstract
Combination limit screw, including screw, stop pad, the fastening end of described screw is designed with endoporus, stop pad is designed to step shaft-like, stop pad smaller diameter end is assembled into interference fit with the endoporus of screw, the big end intended diameter of stop pad is less than the diameter of thread of screw, described screw is steel manufacture, described stop pad uses copper material or the aluminium manufacture of non-ferrous metal, combination limit screw uses as an overall structure securing member, it is the copper material or aluminum material that hardness is low that combination limit screw compresses the contact of connected piece, fastening force does not damage connected piece by pressure according to the frictional force of contact surface.
Description
Technical field
The present invention relates to a kind of mechanical assembling structure and application, belong to machanical fastener, be mainly used in reliability when elevating mechanism securing member uses with
Protective action.
Background technology
Machanical fastener apply in, fastener tip is thermally treated harden after compress connected piece, the contact surface of connected piece can be forced out impression,
Shadow coughs up the surface quality of connected piece, the most also can affect dismounting.
Summary of the invention
For more preferably realizing the interconnection function of machanical fastener, the present invention provides a kind of combination limit screw, utilizes the combination and variation of screw assemblies material to protect
Protect the surface quality of connected piece, low cost and easy to use.
The technical scheme is that the combination limit screw connected for machanical fastener, including screw, stop pad.The fastening end of described screw
Being designed with endoporus, stop pad is designed to step shaft-like, and stop pad smaller diameter end is assembled into interference fit with the endoporus of screw, stop pad hold greatly design
Diameter is less than the diameter of thread of screw, and described screw is steel manufacture, and described stop pad uses copper material or the aluminium manufacture of non-ferrous metal.
During application, combination limit screw uses as an overall structure securing member, and it is that hardness is low that combination limit screw compresses the contact of connected piece
Copper material or aluminium, fastening force does not damage connected piece by pressure according to the frictional force of contact surface.
Accompanying drawing explanation
Accompanying drawing 1 is that the present invention combines limit screw schematic diagram.
Detailed description of the invention
Seeing accompanying drawing, the present invention provides a kind of combination limit screw, including screw 1, stop pad 2.
Screw 1 fastening end of described combination limit screw is designed with endoporus, and stop pad 2 is designed to step shaft-like, stop pad 2 smaller diameter end and screw
The endoporus of 1 is assembled into interference fit, and the big end intended diameter of stop pad 2 is less than the diameter of thread of screw 1, and described screw 1 is steel manufacture,
Described stop pad 2 uses copper material or the aluminium manufacture of non-ferrous metal.
The screw of described combination limit screw uses as an overall structure securing member, and it is that hardness is low that combination limit screw compresses the contact of connected piece
Copper material or aluminium, fastening force does not damage connected piece by pressure according to the frictional force of contact surface.
Claims (2)
1. combination limit screw, it is characterised in that structure includes that screw, stop pad, the fastening end of described screw are designed with endoporus, and stop pad is designed to platform
Rank shaft-like, stop pad smaller diameter end is assembled into interference fit with the endoporus of screw, and the big end intended diameter of stop pad is less than the diameter of thread of screw.
Combining limit screw the most as claimed in claim 1, it is characterised in that the screw in structure is steel manufacture, described stop pad uses coloured gold
The copper material belonged to or aluminium manufacture, combination limit screw uses as an overall structure securing member, and combination limit screw compresses the contact of connected piece
