Abstract
The utility model discloses a multifunctional anti-loose bolt. The multifunctional anti-loose 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 multiple clamping teeth which are bulged downwards, the upper end of the screw rod is a polish rod section, the lower end of the screw rod is a threaded section, the polish rod section is sleeved with a thickened gasket, and one surface,facing the bolt head, of the thickened gasket is provided with multiple clamping grooves corresponding to the multiple clamping teeth. According to the multifunctional anti-loose 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 anti-loose bolt is installed is provided with the installation groove, thus other components can be arranged on the installation surface, the use is convenient, adjacent bolts can be fastened through an iron wire or a similar fastening piece, the vibration-proof performance of the multifunctional anti-loose bolt can be increased, the bolt head can be tightly clamped through the thickened gasket after the multifunctional anti-loose bolt is fastened, the phenomena of looseness and displacement are not easily caused by influence such as vibration, and the fastening effect of the multifunctional anti-loose bolt is ensured.
Description
Technical field
The utility model relates to a kind of mechanical fastener, is specially a kind of multi-functional chek 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, in use easily because reasons such as vibration make bolt looseness or displacement, influences the fastening effect of bolt.
The model utility content
The purpose of this utility model provides a kind of multi-functional chek bolt, and is single to solve bolt function traditional in the prior art, in use easily because reasons such as vibration make bolt looseness or displacement, influences the problem of bolton effect.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of multi-functional chek 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, the lower end surface of described bolt head is provided with several latches that protrudes downwards, described screw rod upper end is the polished rod section, the lower end is thread section, is with the thickening pad on the described polished rod section, and described thickening pad is provided with several draw-in grooves corresponding with several latches towards the one side of bolt head.
Described a kind of multi-functional chek bolt, it is characterized in that: the groove bottom of described annular mounting groove is curved.
Described a kind of multi-functional chek bolt is characterized in that: the quantity of described latch is at least two.
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 several corresponding latches and the design of draw-in groove respectively on bolt head and pad, make that bolt head can tighten by pad after the bolton, thereby influence such as is not subject to vibrate and phenomenon loosening and displacement takes place, and has guaranteed the fastening effect of bolt.
