Abstract
The invention relates a bolt for vacuum equipment, comprising bolt head [01] and bolt body [05]. Outer thread [02] is set on the outer edge face of bolt body [05], one via hole [03] is opened in the bolt body [02] along the axial direction and one via hole [04] is set along the vertical direction with outer edge face of bolt body [05]. Axial air in the top between bolt and screw is removed conveniently by the axial via hole [03] and air between bolt and screw thread on the outer edge face of bolt is removed conveniently so as to help to obtain vacuum of vacuum equipment.
Description
Technical field
The present invention relates to a kind of screw that is used for vacuum system.
Background technique
Various screws are when being used for vacuum system, and are gapped owing to reaching between screw and screw between screw thread, and the gap is little, under screw is not penetrating situation, the gas of depositing in the gap is not easy to be taken away, thereby becomes a venting source of vacuum chamber, influences the acquisition of vacuum.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, propose a kind of screw of new structure.The present invention helps to get rid of the gas that reaches between screw thread between screw and screw, avoids becoming the venting source in vacuum chamber, influences the acquisition of vacuum.
Screw of the present invention is made up of nail body and ailhead, and its structure characteristic is as follows:
Nail body outer edge surface is provided with outside thread, and the nail axon is also having a through hole to having a through hole with nail body outer edge surface Vertical direction.The nail axon is convenient to get rid of the gas of screw and screw head room to through hole, and the through hole of following closely body outer edge surface Vertical direction is convenient to get rid of the gas between screw and screw outer edge surface screw thread.
Description of drawings
Accompanying drawing is the structural drawing of screw of the present invention, and among the figure: the outside thread 02 that screw head 01, outer edge surface are provided with, nail axon are to through hole 03, and nail body outer edge surface Vertical direction through hole 04 is followed closely body 05, screw and screw head room 06.
Embodiment
Further specify the present invention below in conjunction with the drawings and the specific embodiments.Screw of the present invention is made up of ailhead 01 and nail body 05.Nail body 05 outer edge surface is provided with outside thread 02, nail body 05 axially have a through hole 03, having a through hole 04 again with nail body 05 outer edge surface Vertical direction.Axial through hole 03 is convenient to get rid of the gas of screw and screw head room 06, and the through hole 04 of Vertical direction is convenient to get rid of the gas between screw and screw outer edge surface screw thread, thereby helps the vacuum of vacuum system to obtain.
Claims (1)
- A kind of screw that is used for vacuum system is made up of ailhead [01] and nail body [05], and nail body [05] outer edge surface is provided with outside thread [02], and what it is characterized in that following closely body [05] axially has a through hole [03], with follow closely body [05] outer edge surface Vertical direction and having a through hole [04].
