Abstract
The utility model discloses a multifunctional bolt. The multifunctional bolt comprises a bolt head and a screw rod, wherein the bolt head is of a cylindrical shape, the side wall of the bolt head is provided with an annular installation groove, the lower end surface of the bolt head is provided with an annular groove surrounding the screw rod, the annular groove is internally embedded with a sealing rubber ring, the upper end of the screw rod is a polish rod section, the lower end of the screw rod is a threaded section, and the threaded section is provided with a shallow groove which is parallel to an axis of the screw rod. According to the multifunctional bolt disclosed by the utility model, the structure is simple and reasonable, the bolt head which is left on an installation surface after the multifunctional bolt is installed is provided with the installation groove, thus other components can be arranged on the installation surface, the use is convenient, and the multifunctional bolt has a sealing function after being installed and can be applied to a machine which has higher requirements on sealing performance; and convenience is effectively brought for disassembling operation by adding lubricating oil from the shallow groove when the multifunctional bolt is not easily disassembled due to rusting.
Description
Technical field
The utility model relates to a kind of mechanical fastener, is specially a kind of multi-functional bolt.
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, does not possess the performance of sealing, be not suitable in the higher machine of sealing requirements, and after long-time the use, bolt is fixed together with nut because getting rusty easily, and dismounting is convenient inadequately.
The model utility content
The purpose of this utility model provides a kind of multi-functional bolt, single to solve bolt function traditional in the prior art, the performance that does not possess sealing, be not suitable in the higher machine of sealing requirements, and after long-time the use, bolt is fixed together with nut because getting rusty easily, dismantles inadequately problem easily.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of multi-functional bolt, 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, and described thread section is provided with the shallow slot parallel with screw axis.
Described a kind of multi-functional bolt, it is characterized in that: the groove bottom of described annular mounting groove is curved.
Described a kind of multi-functional bolt, it is characterized in that: described sealing rubber ring slightly protrudes from the bolt head lower end surface.
Described a kind of multi-functional bolt, it is characterized in that: described shallow slot is at least one, and the shallow slot degree of depth is 1-3mm.
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; Employing arranges the design of shallow slot in the screw flight section, when not quick detachable because get rusty when bolt, can add lubricant oil from shallow slot, thereby make things convenient for disassembling section effectively.
