Abstract
The utility model provides a labor-saving and power saving bolt, which comprises a bolt head and a screw, wherein a connecting piece is arranged between the bolt head and the screw; a first supporting leg and a second supporting leg are arranged below the screw; a gap is formed between the first supporting leg and the second supporting leg; the depth of the gap is 20-40mm; the bolt head is provided with a multi-edge cover; and the lower end of the multi-edge cover is provided with anti-skidding teeth. The utility model aims to design the labor-saving and power saving bolt, the stressed area of the bolt is enlarged by the arrangement of the multi-edge cover, labor and power are saved when an object is fixed by the bolt, and the bolt is prevented from skidding by the anti-skidding teeth when being used for fixing.
Description
Technical field
The utility model relates to technical field of fastening, particularly a kind of screw of lowering and work-saving.
Background technique
Screw is a class fastening piece that is made of head and screw rod two-part, can be divided three classes by purposes: machine screw, Cock screw and specific use screw, machine screw is mainly used in the part of a clamp screw pit, and one with being fastenedly connected between the part of through hole, (this Connecting format is called screw and connects, and also belongs to removably connect not need the nut cooperation; Also can cooperate with nut, be used for two with being fastenedly connected between the part of through hole.) Cock screw is mainly used in fixing two relative positions between the part, the specific use screw is such as lifting bolt etc. being arranged for the lifting part.
Common screw is with object fixedly the time, if fix or be subjected to for a long time the vibration of machine, the phenomenon that usually comes off causes the fault of machine, has affected the working life of machine, when set screw, often need larger power, common screw easily ruptures, and the life-span is short, also than being easier to skew, working life is short when mounted for screw commonly used.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of screw of lowering and work-saving, the lifting surface area that the increase screw is set of polygon cover makes screw lowering and work-saving when fixed object, and the setting of slideproof tooth prevents that screw from skidding fixedly the time.
The utility model provides a kind of screw of lowering and work-saving, described screw comprises screw head, screw rod, between described screw head and screw rod, be provided with link, have supporting leg one and supporting leg two at described screw rod, gapped between described supporting leg one and the supporting leg two, the degree of depth in gap is 20-40mm, at described screw head polygon cover is installed, and described polygon cover lower end is provided with slideproof tooth.The purpose of this utility model designs a kind of screw of lowering and work-saving, the lifting surface area that the increase screw is set of polygon cover, make screw lowering and work-saving when fixed object, the setting of slideproof tooth prevents that screw from skidding fixedly the time, the effective fixed object in gap between supporting leg one and the supporting leg two, prevent coming off of screw, and simple installation, the efficient of installing improved.
The utility model discloses a kind of a kind of improvement of screw of lowering and work-saving, described slideproof tooth is symmetrical set, and described slideproof tooth is at least 3 roads.This improvement slideproof tooth is symmetrical set, and prevents the phenomenon that screw skids fixedly the time.
The utility model discloses a kind of a kind of improvement of screw of lowering and work-saving, the length of described supporting leg one and supporting leg two is 1/3rd of spiro rod length.This improvement equates its width, guarantees the soundness of screw, prolongs the working life of screw.
The purpose of this utility model designs a kind of screw of lowering and work-saving, the lifting surface area that the increase screw is set of polygon cover, make screw lowering and work-saving when fixed object, the setting of slideproof tooth prevents that screw from skidding fixedly the time, the effective fixed object in gap between supporting leg one and the supporting leg two, prevent coming off of screw, and simple installation, the efficient of installing improved.
