Abstract

The utility model discloses a multifunctional disassembling and assembling bolt. The bolt comprises a bolt rod and an outer hexagonal bolt head; an inner hexagonal groove is arranged in the outer hexagonal bolt head; a cambered surface projection structure is arranged in the groove; and a cross groove is arranged in the cambered surface projection structure. The bolt is simple in structure and easy to operate; it can be effectively achieved that disassembling and assembling can be flexibly and easily performed in an individual or combined manner by use of a plurality of tools such as a slotted screwdriver, a cross screwdriver, an open spanner, a box spanner, a socket spanner in different forms; it is effectively prevented that a traditional inner hexagonal bolt of an outer hexagonal bolt fails to be normally disassembled and assembled once corner angles are worn; and disassembling and assembling tool are varied, so working efficiency is greatly increased.

Description

A kind of Multi-functional foldable bolt

Technical field

The utility model relates to electric armour clamp technical field, relates in particular to a kind of Multi-functional foldable bolt.

Background technique

Due to the particularity of power equipment, normally used most of bolt is hexagon socket head cap screw, only have the inner hexagon spanner of use just can carry out dismounting operation, after being dismounted for multiple times, the interior rib meeting abrasion deformation of the outer rib of inner hexagon spanner or hexagon socket head cap screw, in disassembly process easily because of stressed excessive skidding, not only affect dismounting and the fastening degree of bolt, also directly have influence on the repair quality of equipment and maintainer's personal safety, cause work to be subject to significant limitation, badly influence the working efficiency of construction and upkeep operation.

Authorizing disclosed application number on July 31st, 2013 is that 201320122046.1 utility model patent discloses a kind of multi-functional connecting bolt, comprise screw rod, described screw rod upper end is provided with hexagonal spiral shell head, on described hexagonal spiral shell head, has connecting groove, and described hexagonal spiral shell head sidewall is provided with tapped through hole.Its deficiency is: hexagonal structure in lacking, and cannot use inner hexagon spanner to enter operation, be not suitable for applying on power equipment.

Model utility content

The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, dismounting is various informative and have the Multi-functional foldable bolt of interior hexagonal structure.

For realizing the technological scheme that the purpose of this utility model adopts, be: a kind of Multi-functional foldable bolt, comprise bolt shank and outer-hexagonal bolt head, in described outer-hexagonal bolt head, be provided with the groove of interior hexagonal, in described groove, be provided with cambered surface protruding structure, on described cambered surface protruding structure, be provided with cross recess.

On described outer-hexagonal bolt head, be provided with through hole.

In described through hole, be provided with antiskid thread.

Described cambered surface protruding structure is provided with hard alloy layer.

Multi-functional foldable bolt of the present utility model is by arranging the groove of interior hexagonal in hex head bolt head outside, and arrange and there is the cambered surface protruding structure of cross recess in groove, simple in structure, easy and simple to handle, effectively realized use flat mouth screw-driver, Phillips screwdriver, open-end wrench, plum blossom shaped spanner, the multiple types of tools such as socket wrench carry out dismounting alone or in combination, form is varied, flexibly, convenient, once effectively avoid the just normally situation of dismounting generation of traditional hexagon socket head cap screw or the wearing and tearing of outer-hexagonal bolt corner angle, dismantling device variation, greatly improved operating efficiency, on outer-hexagonal bolt head, through hole is set, when after corner angle wearing and tearing, can to bolt, carries out dismounting by through hole, antiskid thread is set in through hole, the generation of the situation of skidding while avoiding dismounting, the safety and stability while ensureing operation, cambered surface protruding structure arranges hard alloy layer, has greatly improved the antiwear property of cambered surface protruding structure, the utility model structure letter practicality just, cost is low, and cost performance is high, has extended the working life of bolt, has reduced the cost that operation of power networks is safeguarded, use should be widely promoted.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is described further:

Fig. 1 is plan structure schematic diagram of the present utility model;

Fig. 2 is side-looking structural representation of the present utility model.

Embodiment

As shown in Figure 1 and Figure 2: a kind of Multi-functional foldable bolt, comprise bolt shank 5 and outer-hexagonal bolt head 3, in described outer-hexagonal bolt head 3, be provided with the groove 2 of interior hexagonal, in described groove 2, be provided with cambered surface protruding structure 4, on described cambered surface protruding structure 4, be provided with cross recess 1, on described outer-hexagonal bolt head 3, be provided with through hole 6, in described through hole 6, be provided with antiskid thread, described cambered surface protruding structure 4 is provided with hard alloy layer.

Multi-functional foldable bolt of the present utility model is by arranging the groove of interior hexagonal in hex head bolt head outside, and arrange and there is the cambered surface protruding structure of cross recess in groove, simple in structure, easy and simple to handle, effectively realized use flat mouth screw-driver, Phillips screwdriver, open-end wrench, plum blossom shaped spanner, the multiple types of tools such as socket wrench carry out dismounting alone or in combination, form is varied, flexibly, convenient, once effectively avoid the just normally situation of dismounting generation of traditional hexagon socket head cap screw or the wearing and tearing of outer-hexagonal bolt corner angle, dismantling device variation, greatly improved operating efficiency, on outer-hexagonal bolt head, through hole is set, when after corner angle wearing and tearing, can to bolt, carries out dismounting by through hole, antiskid thread is set in through hole, the generation of the situation of skidding while avoiding dismounting, the safety and stability while ensureing operation, cambered surface protruding structure arranges hard alloy layer, has greatly improved the antiwear property of cambered surface protruding structure, the utility model structure letter practicality just, cost is low, and cost performance is high, has extended the working life of bolt, has reduced the cost that operation of power networks is safeguarded, use should be widely promoted.
