Abstract
The utility model discloses an anti-vibration and easy-assembly and disassembly check bolt, which comprises a bolt head and a screw, wherein the side edge of the bolt head is provided with a pin plate which extends towards one side; the pin plate is provided with a pin hole; the lower end face of the bolt head is provided with a plurality of clamping teeth which protrude downwards; the upper end of the screw is a polished rod section, and the lower end of the screw is a threaded section; a thickened spacer is sleeved on the polished rod section; one face of the thickened spacer facing the bolt head is provided with a plurality of clamping grooves corresponding to the clamping teeth; and the threaded section is provided with a shallow groove which is parallel to the axis of the screw. The anti-vibration and easy-assembly and disassembly check bolt is of a simple structure and is convenient to use, the anti-vibration performance of the bolt is effectively improved, the bolt head can be clamped tightly through the spacer after the bolt is fastened, so that phenomena of loosening and displacement are not easily caused due to influence of vibration and the like, and the fastening effect of the bolt is guaranteed, and lubricating oil can be added from the shallow groove, so that the disassembly operation is effectively facilitated.
Description
Technical field
The utility model relates to a kind of mechanical fastener, is specially the locking quick detachable bolt of a kind of antivibration.
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.In use easily because reasons such as vibration make bolt looseness, displacement, influence fastening effect and corrosion-resistant, be subjected to corrosion to influence and lost efficacy easily, and then influence the use safety of equipment, and after the long-time 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 the locking quick detachable bolt of a kind of antivibration, in use easy because vibration etc. are former thereby make bolt looseness, displacement to solve bolt traditional in the prior art, influence fastening effect, 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:
The locking quick detachable bolt of a kind of antivibration, include bolt head and screw rod, it is characterized in that: described bolt head side is provided with the pin plate that extends to a side, described pin plate is provided with pin-and-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.
The locking quick detachable bolt of described a kind of antivibration is characterized in that: described bolt head is cylindrical no bevel bolt head.
The locking quick detachable bolt of described a kind of antivibration is characterized in that: the quantity of described latch is at least two.
The locking quick detachable bolt of described a kind of antivibration, 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 in structure, and is easy to use, adopts the design that pin plate is set at the bolt head side, can insert latch down by pin-and-hole after bolt is installed, and improved the resistance to shock of bolt effectively; 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.
