Abstract
A kind of easy-to-use type fastening screw of the utility model design, main body is screw, comprise screw terminal and cylindrical lead screw, screw terminal is fixedly installed on lead screw one end, lead screw surface is provided with screw thread, and lead screw the other end side is provided with fluting, is acclivitous domatic gradually to screw terminal one end bottom described fluting, groove width is 1/3 ~ 2/3 of lead screw diameter, and groove depth biggest place is 1/2 ~ 3/4 of lead screw diameter.Utilize dilating principle to realize screw expansion reinforcement connection tightness in screw hole in use, improve Whole Equipment stablizing effect.Also comprise spring assembly, effectively prevent lead screw end from excessive deformation occurring in the case of crushing, thus affect the expansion effect of screw.
Description
technical field:
The utility model relates to screw part, particularly relates to a kind of easy-to-use type fastening screw.
background technique:
Screw utilizes the inclined-plane circular rotating of object and the physics of frictional force and mathematical principle, the by easy stages instrument of fastening implements parts.Screw is the general saying of fastening piece, daily pet phrase.Screw is industrial necessity indispensable in daily life: the minimum screw used as photographic camera, glasses, clock and watch, electronics etc.; The general screw of TV, electric product, musical instrument, furniture etc.; Large-scale screw, nut is then used as engineering, building, bridge; Traffic tool, aircraft, electric car, automobile etc. then sized by screw using.Screw industrially bears vital task, as long as the earth also exists industry, then the function of screw is forever important.Screw is the joint invention over the past thousands of years in people's productive life, and according to application, it is the first invention of the mankind.
Screw, also someone is its " screw " (screw), " screw rod " (lead screw).Screw is common name in fact, and screw, lead screw are all distinguishing mutually.Screw is generally WOOD SCREWS; Be that front end is acuminous that, pitch is comparatively large, is generally used for fastening wooden part, working of plastics.Lead screw is machine screw (MACHINE SCREWS), and be that of front end tack, pitch is less, evenly, is generally used for fastening metal, machine part.
Traditional screw due to reinforcing mechanical parts, the process that connects time normally rely on the screw thread cooperatively interacted to be engaged and then to realize.But because the situation of stripped thread easily occurs screw in rundown process, cause connection not tight, easily loosen, the problem of the stability of impact machinery.
model utility content:
In order to solve the problem, it is more accurate that the utility model provides a kind of structure, utilizes dilating principle to realize screw expansion reinforcement connection tightness in screw hole in use, improve the technological scheme of Whole Equipment stablizing effect:
A kind of easy-to-use type fastening screw, main body is screw, comprise screw terminal and cylindrical lead screw, screw terminal is fixedly installed on lead screw one end, lead screw surface is provided with screw thread, and lead screw the other end side is provided with fluting, and fluting bottom is acclivitous domatic gradually to screw terminal one end, groove width is 1/3 ~ 2/3 of lead screw diameter, and groove depth biggest place is 1/2 ~ 3/4 of lead screw diameter.
As preferably, also comprise spring assembly, spring assembly is N >=1, and spring assembly two ends are fixedly installed on the corresponding sidewall of fluting inner chamber.
As preferably, screw terminal is positive six prism structures, and screw terminal lateral ends arranges interior hexagonal screw, arranges cross screw bottom interior hexagonal screw.
As preferably, fluting neutral position is vertically installed with a circular connection mouth, and connection mouth diameter is greater than groove width 0.5 ~ 1.5mm.
The beneficial effects of the utility model are:
(1) the utility model structure is more accurate, lead screw one end side is provided with fluting, fluting bottom is acclivitous domatic gradually to screw terminal one end, utilizes dilating principle to realize screw expansion reinforcement connection tightness in screw hole in use, improves Whole Equipment stablizing effect.
(2) also comprise spring assembly in the utility model, effectively prevent lead screw end from excessive deformation occurring in the case of crushing, thus affect the expansion effect of screw.
(3) in model utility, screw terminal is positive six prism structures, screw terminal lateral ends arranges interior hexagonal screw, bottom interior hexagonal screw, cross screw is set, in use can carry out tightening operation by spanner wrench, interior hexagonal, Phillips screwdriver and straight screwdriver to high screw, the operation tool adapted to is many, uses under being applicable to multiple operating environments.
(4) neutral position of slotting in model utility is vertically installed with a circular connection mouth, when this screw is applied in relatively large structure, can increases screw overall construction intensity, coordinating production further by placing corresponding contiguous block in connection mouth.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model sectional view;
Fig. 3 is screw terminal end construction schematic diagram.
embodiment:
For making goal of the invention of the present utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, mode of execution of the present utility model is described in further detail.
As Fig. 1, shown in Fig. 2, the utility model devises a kind of easy-to-use type fastening screw, main body is screw, comprise screw terminal 1 and cylindrical lead screw 2, screw terminal 1 is fixedly installed on lead screw 2 one end, lead screw 2 surface is provided with screw thread 3, lead screw 2 the other end side is provided with fluting 4, be acclivitous domatic gradually to screw terminal 1 one end bottom fluting 4, 4 width of slotting are 1/3 ~ 2/3 of lead screw 2 diameter, 4 degree of depth biggest places of slotting are 1/2 ~ 3/4 of lead screw 2 diameter, its structure is more accurate, dilating principle is utilized to realize screw expansion reinforcement connection tightness in screw hole in use, improve Whole Equipment stablizing effect.
Also comprise spring assembly 5, spring assembly 5 is N >=1, and spring assembly 5 two ends are fixedly installed on the corresponding sidewall of fluting 4 inner chamber.Effectively prevent lead screw 2 end from excessive deformation occurring in the case of crushing, thus affect the expansion effect of screw.
As shown in Figure 3, screw terminal 1 is positive six prism structures, and screw terminal lateral ends arranges interior hexagonal screw 6, arranges cross screw 7 bottom interior hexagonal screw 6.In use can carry out tightening operation by spanner wrench, interior hexagonal, Phillips screwdriver and straight screwdriver to high screw, the operation tool of adaptation is many, uses under being applicable to multiple operating environments.
Meanwhile, 4 neutral positions of slotting are vertically installed with a circular connection mouth 8, and connection mouth 8 diameter is greater than fluting 4 width 0.5 ~ 1.5mm.When this screw is applied in relatively large structure, screw overall construction intensity can be increased by placing corresponding contiguous block in connection mouth 4, coordinating production further.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technological scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
