Abstract
The utility model discloses a multifunctional pre-tightening type easy-to-disassemble bolt. The pre-tightening type easy-to-disassemble 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 a step, an annular groove is arranged between the step and the edge of the lower end surface of the bolt head, 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 gasket, a spring is connected between the gasket and the bolt head, the upper end of the spring is clamped in the annular groove, and the threaded section is provided with a shallow groove which is parallel to an axis of the screw rod. According to the multifunctional pre-tightening type easy-to-disassemble 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 pre-tightening type easy-to-disassemble bolt is installed is provided with the installation groove, thus other components can be arranged on the installation surface, the use is convenient, the phenomenon that the multifunctional pre-tightening type easy-to-disassemble bolt rotates along with a nut can be effectively prevented from happening, the working efficiency is increased, and convenience is effectively brought for disassembling operation by adding lubricating oil from the shallow groove.
Description
Technical field
The utility model relates to a kind of mechanical fastener, is specially the quick detachable bolt of a kind of multi-functional pre-tensioned type.
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 existing bolt function is single, the fitting operation inconvenience, when nut begins to screw, bolt is followed nut easily and is rotated together, makes nut disposablely not screw, and has prolonged the operating time, inefficiency, 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 the quick detachable bolt of a kind of multi-functional pre-tensioned type, single to solve bolt function traditional in the prior art, the fitting operation inconvenience, when nut began to screw, bolt was followed nut easily and is rotated together, make nut disposablely not screw, prolonged the operating time, inefficiency, 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 quick detachable bolt of a kind of multi-functional pre-tensioned type, 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 step, be provided with annular groove between the edge of described step and bolt head lower end surface, described screw rod upper end is the polished rod section, the lower end is thread section, be with pad on the described polished rod section, be connected with spring between described pad and the bolt head, described spring upper end is clamped in the annular groove, and described thread section is provided with the shallow slot parallel with screw axis.
The quick detachable bolt of described a kind of multi-functional pre-tensioned type, it is characterized in that: the groove bottom of described annular mounting groove is curved.
The quick detachable bolt of described a kind of multi-functional pre-tensioned type, 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 connects the design of pad by spring in the bolt head lower end surface, when bolts and nuts connect, pad pushes against at part surface by spring, make bolt head obtain certain pressure, along with screwing of nut, this pressure is more big, has prevented that effectively bolt from following the generation of nut rotation phenomenon, has improved working efficiency; 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.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
