Abstract
The utility model discloses a locking easily-detachable bolt which comprises a bolt head and a screw rod, wherein a plurality of latches protruding downwards are arranged on the lower end surface of the bolt head; a polished rod section is arranged at the upper end of the screw rod; a thread section is arranged at the lower end of the screw rod; a thickened gasket is sheathed on the polished rod section; a plurality of clamping grooves corresponding to the latches are formed in one surface, which faces to the bolt head, of the thickened gasket; and a shallow groove parallel to the axis of the screw rod is formed in the thread section. The locking easily-detachable bolt disclosed by the utility model is simple in structure and is convenient to use; the bolt head can be clamped by the gasket after the bolt is fastened, so that the probabilities that the bolt loosens and displaces due to vibration are reduced and the fastening effect of the bolt is ensured; and when the bolt is not easy to detach due to rusting, lubricating oil can be added from the shallow groove, and thus the detaching operation is effectively facilitated.
Description
Technical field
The utility model relates to a kind of mechanical fastener, is specially a kind of locking quick detachable bolt.
Background technique
Bolt generally is used for fastening, location, in use can make bolt looseness or displacement because of reasons such as vibrations, some locking measure will be based upon on the fastened basis of bolt, such as elastic washer, but in the application that prevents from being shifted, because bolt does not possess fastened condition, a lot of locking measures can't be used, get hanger bolt such as the suspending type sliding door, its fastening force is exactly the weight of hanging door, and general locking measure can't be used, 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 locking quick detachable bolt, to solve bolt traditional in the prior art in use owing to former thereby loosening or displacements easily such as vibrations, 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:
A kind of locking quick detachable bolt, include bolt head and screw rod, it is characterized in that: 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 locking quick detachable bolt is characterized in that: described bolt head is cylindrical no bevel bolt head.
Described a kind of locking quick detachable bolt, it is characterized in that: the quantity of described latch is at least two.
Described a kind of locking quick detachable 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 in structure, easy to 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 be not subject to vibrate and phenomenon loosening and displacement takes place, 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.
