Abstract
The utility model discloses a sealing bolt with a mounting function. The sealing bolt comprises a bolt head and a screw, wherein the bolt head is cylindrical and the side wall is provided with an annular mounting groove; the lower end face of the bolt head is provided with an annular groove around the screw; a seal rubber ring is embedded in the annular groove; and the upper end of the screw is a polished rod section, and the lower end of the screw is a threaded section. The sealing bolt is of a simple and rational structure; the bolt head which remains on a mounting surface is provided with the mounting groove after the bolt is mounted, so that other components can be mounted on the mounting surface, and convenience is brought to use; adjacent bolts can also be locked through an iron wire or a similar buckle, so that the anti-vibration performance of the bolt is improved; and the design that the seal rubber ring is arranged on the lower end face of the bolt head is adopted, so that the bolt has a sealing function after being mounted and can be applied to a machine with higher requirements on sealing property, and the application range of the bolt is expanded.
Description
Technical field
The utility model relates to a kind of mechanical fastener, is specially a kind of sealing bolt with installation function.
Background technique
Bolt is one of modal fastening piece, and it is made up of head and screw rod.It is cylindric that screw rod is, on have outside thread and can use with nut collocation.Screw bolt and nut uses jointly, can connect and fix two parts that have through hole.And traditional bolt function is single, and does not possess the performance of sealing, is not suitable in the higher machine of sealing requirements.
The model utility content
The purpose of this utility model provides a kind of sealing bolt with installation function, and is single to solve bolt function traditional in the prior art, and do not possess the performance of sealing, is not suitable for the problem in the higher machine of sealing requirements.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of sealing bolt with installation function, include bolt head and screw rod, it is characterized in that: the cylindrical and sidewall of described bolt head is provided with annular mounting groove, described bolt head lower end surface is provided with the annular groove around screw rod, be embedded with sealing rubber ring in the described annular groove, described screw rod upper end is the polished rod section, and the lower end is thread section.
Described a kind of sealing bolt with installation function, it is characterized in that: the groove bottom of described annular mounting groove is curved.
Described a kind of sealing bolt with installation function, it is characterized in that: described sealing rubber ring slightly protrudes from the bolt head lower end surface.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, employing arranges the design of annular mounting groove at the bolt head sidewall, the bolt head that bolt is stayed on the attachment face after installing has mounting groove, therefore can miscellaneous part be installed at attachment face, the convenient use, also can adjacent bolt be locked by iron wire or similar fastener, improve the resistance to shock of bolt; Employing arranges the design of sealing rubber ring in the bolt head lower end surface, make to have sealing function after the bolt installation, can apply to in the higher machine of sealing requirements, has enlarged its using scope.
