Abstract
The utility model discloses a multifunctional anti-loose type special-shaped bolt. The multifunctional anti-loose type special-shaped bolt comprises a bolt head and a screw rod, wherein the upper end surface of the bolt head is vertically provided with an installation convex block, the installation convex block is provided with an installation hole, 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 polished rod section is sleeved with a thickened gasket, one surface,facing the bolt head, of the thickened gasket is provided with multiple clamping grooves corresponding to the multiple clamping teeth, and the threaded section is provided with a shallow groove which is parallel to an axis of the screw rod. According to the multifunctional anti-loose type special-shaped bolt disclosed by the utility model, the structure is simple and reasonable, the bolt head can be tightly clamped through the thickened gasket after the multifunctional anti-loose type special-shaped bolt is fastened, the fastening effect is better, the bolt head which is left on an installation surface after the multifunctional anti-loose type special-shaped bolt is installed is provided with the installation hole, thus other components can be installed on the installation surface, the use is convenient, and convenience is effectively brought for the disassembling operation by adding lubricating oil from the shallow groove when the multifunctional anti-loose type special-shaped 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 anti-easing special shaped screw 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, 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 anti-easing special shaped screw bolt, single to solve bolt function traditional in the prior art, in use easily because reasons such as vibration make bolt looseness or displacement, influence the fastening effect of bolt, 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 anti-easing special shaped screw bolt, include bolt head and screw rod, it is characterized in that: described bolt head upper-end surface vertically is provided with the installation projection, described installation projection is provided with mounting hole, 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, be with the thickening pad on the described polished rod section, described thickening pad is provided with several draw-in grooves corresponding with several latches towards the one side of bolt head, and described thread section is provided with the shallow slot parallel with screw axis.
Described a kind of multi-functional anti-easing special shaped screw bolt, it is characterized in that: the quantity of described latch is at least two.
Described a kind of multi-functional anti-easing special shaped screw bolt, it is characterized in that: described shallow slot is at least one, and the shallow slot degree of depth is 1-2mm.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, adopts in the bolt head upper-end surface design that projection is installed is set, and the bolt head that bolt is stayed on the attachment face after installing has mounting hole, therefore can miscellaneous part be installed at attachment face, the convenient use; 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; 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.
