Abstract
The utility model relates to a srew, including nut, intermediate lever and ejector pin, the inside hole groove that is equipped with of nut, the intermediate lever both ends are located respectively to nut and ejector pin, and the peripheral spiral of intermediate lever is equipped with the intermediate lever thread, and the ejector pin includes link, drilling portion and buffering portion, and the intermediate lever is connected to the link, and buffering portion both ends are do not located with the drilling part to the link, and the toper gradient of drilling portion is greater than the toper gradient of buffering portion, and the peripheral spiral of drilling portion and buffering portion is equipped with matched with ejector pin thread. Compared with the prior art, the utility model has following advantage: fastening nature is good, the difficult slope of srew bottle opener, the obscission of taking place, and the fine fixed required part of ability, long service life, work efficiency is high, convenient to popularize and use.
Description
Technical field
The utility model relates to a kind of screw, belongs to technical field of fastening.
Background technique
Screw belongs to a kind of fastening piece, and it matches with screw and is combined into an assembly parts for by various part, and makes part easily assemble or dismantle.But when the assembly parts including screw is for particular surroundings, such as, when using in outdoor application or liquid environment, just screw closure place is had to the requirement preventing liquid from leaking via screw junction and preventing screw from getting loose, common screw structural does not then have such function.Fastened by screw is in the prior art poor, easily obscission occurs.
Therefore, a kind of new technological scheme should be provided to solve the problem.
Summary of the invention
The utility model provides a kind of screw.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of screw, comprise nut, intermediate bar and push rod, nut inside is provided with hole slot, intermediate bar two ends are located at respectively by nut and push rod, and the peripheral spiral of intermediate bar is provided with intermediate bar thread, and push rod comprises connecting end, bore portion and buffer part, connecting end connects intermediate bar, connecting end and bore portion are located at buffer part two ends respectively, and the taper inclination of bore portion is greater than the taper inclination of buffer part, and bore portion and the peripheral spiral of buffer part are provided with the push rod thread matched.
The related content of technique scheme is explained as follows:
In technique scheme, be provided with joint between nut and intermediate bar, joint is arc shaped surface, and joint is provided with reinforced sheet.
Further technological scheme, outermost end and the intermediate bar thread outermost end of connecting end are positioned at same straight line.
Preferably, be provided with auxiliary rod between intermediate bar and push rod, auxiliary rod inside is provided with arc-shaped concave.
Because technique scheme is used, the utility model compared with prior art has following advantages:
Tightness is good, and screwdriver inclination, obscission not easily occur, and well can fix required parts, long service life, working efficiency is high, is convenient to promote the use of.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model schematic diagram.
In above accompanying drawing: 1, nut; 2, intermediate bar; 3, auxiliary rod; 4, hole slot; 5, intermediate bar thread; 6, connecting end; 7, bore portion; 8, buffer part; 9, push rod thread; 10, joint; 11, arc-shaped concave; 12, reinforced sheet; .
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
As shown in Figure 1, a kind of screw of the present utility model, comprise nut 1, intermediate bar 2 and push rod, nut 1 inside is provided with hole slot 4, intermediate bar 2 two ends are located at respectively by nut 1 and push rod, the peripheral spiral of intermediate bar 2 is provided with intermediate bar thread 5, push rod comprises connecting end 6, bore portion 7 and buffer part 8, connecting end 6 connects intermediate bar 2, connecting end 6 and bore portion 7 are located at buffer part 8 two ends respectively, the taper inclination of bore portion 7 is greater than the taper inclination of buffer part 8, bore portion 7 and the peripheral spiral of buffer part 8 are provided with the push rod thread 9 matched, joint 10 is provided with between nut 1 and intermediate bar 2, joint 10 is arc shaped surface, joint 10 is provided with reinforced sheet 12, auxiliary rod 3 is provided with between intermediate bar 2 and push rod 3, auxiliary rod 3 inside is provided with arc-shaped concave 11, the effect of buffering can also be played while conservation, outermost end and intermediate bar thread 5 outermost end of connecting end 6 are positioned at same straight line, the diameter of nut 1 is greater than all parts, tightness is good, not easily there is screwdriver to tilt, obscission, well can fix required parts, long service life, working efficiency is high, be convenient to promote the use of.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
