Description

A kind of compression spring

Technical field

It the utility model is related to spring technical field, more particularly to a kind of compression spring.

Background technology

Compression spring is subject to the helical spring of axial compressive force, has certain gap between the circle and circle of compression spring, Spring contraction deforms when by external applied load, stores deformation energy.Compression spring is generally equal pitch, isometrical setting and had solid Fixed line footpath.In actual production, in the very high product of assembling accuracy, compression spring such as is socketed on into fit-up gap will , it is necessary to which compression spring there should be certain elastic force when asking on the strict product of comparison, possess certain rigidity again, that is, need Wanting spring, its deformation does not interfere with the use of product when compressed, it is necessary to meets the fit-up gap of product, otherwise will cause to produce Product normally can not be assembled and used.And the bracing ring due to existing compression spring and coil are typically all isometrical, then have Because deformation can usually exceed the diameter of bracing ring when effect circle is compressed, and then the accuracy of product installation is had influence on, even resulted in Product normally can not be assembled and used.

Therefore, a kind of simple in construction, reasonable in design and high compression spring of installation accuracy is needed badly to overcome above mentioned problem.

Utility model content

The purpose of this utility model is to provide a kind of compression spring simple in construction, reasonable in design and installation accuracy is high.

To achieve these goals, the utility model discloses a kind of compression spring, including the bracing ring at both ends and it is located at Coil between two bracing rings, the outside dimension d1 of the coil, the outside dimension D of the bracing ring and the pressure The line footpath size d of contracting spring magnitude relationship is：D-d<d1<D-d/4.

It is preferred that the number of turns of the coil is at least two circles, and the outside dimension respectively enclosed is identical.

It is preferred that the number of turns of the coil is at least two circles, and the outside dimension respectively enclosed differs.

It is preferred that the surface of the compression spring has an antirust coat.

It is preferred that the free height size h of the compression spring is 24.7-25.3mm, the line footpath size d is 1mm, institute The number of total coils for stating compression spring is 5 circles, and the number of turns of the coil is 2 circles, and the outside dimension D of the bracing ring is 16.5- 16.8mm。

Compared with prior art, compression spring disclosed in the utility model includes the bracing ring at both ends and positioned at two branch Coil between support ring, the outside dimension d1 of the coil, the outside dimension D of the bracing ring and the compression spring Line footpath size d magnitude relationship is：D-d<d1<D-d/4.Just because of the coil of compression spring of the present utility model, support The setting of size between circle and line footpath so that when compression spring is compressed, the deformation range of its coil without departing from The external diametrical extent of bracing ring, then the deformation range of compression spring meet the fit-up gap of product, the normal dress of product will not be hindered Match somebody with somebody and use.The problem of improving the installation accuracy in limited installing space so that compression spring is possessing elastic force While, possess required rigidity requirement.Compression spring of the present utility model is simple in construction, and structure proportion is reasonable in design, practical Property it is strong and effectively increase assembling accuracy.

Brief description of the drawings

Fig. 1 is the structural representation of the utility model compression spring.

Embodiment

To describe technology contents of the present utility model, construction feature, the objects and the effects in detail, below in conjunction with implementation Mode simultaneously coordinates accompanying drawing to be explained in detail.

Referring to Fig. 1, the utility model discloses a kind of compression spring 100, including the bracing ring 10 at both ends and positioned at two Coil 20 between bracing ring 10, the outside dimension d1 of coil 20 between bracing ring 10 outside dimension D with it is middle through size Between, specifically, the outside dimension D's of the outside dimension d1 of coil 20, the bracing ring 10 and line footpath size d of compression spring is big Small relation is：D-d<d1<D-d/4.

Specifically, the outside dimension that the number of turns of coil 20 is at least two circles and respectively enclosed is identical.It can certainly be arranged to, The outside dimension that the number of turns of coil 20 is at least two circles and respectively enclosed differs, as long as the pitch of the laps of largest outside diameter in coil 20 Size is no more than D-d/4.

Specifically, compression spring 100 of the present utility model is coiled to form by a wire, specially piano wire, and effectively It is the setting of equal pitch between each circle of circle 20.

Specifically, the surface of compression spring 100 of the present utility model also has an antirust coat, and the longevity is used so as to improve it Life.

Specifically, the free height size h of compression spring 100 of the present utility model is 24.7-25.3mm, line footpath size d For 1mm, the number of total coils of compression spring 100 is 5 circles, and the number of turns of its coil 20 is 2 circles, and the outside dimension D of bracing ring 10 is 16.5-16.8mm。

Compared with prior art, compression spring 100 disclosed in the utility model includes the bracing ring 10 at both ends and positioned at two Coil 20 between bracing ring 10, the outside dimension d1 of coil 20, the outside dimension D of bracing ring 10 and line footpath size d's Magnitude relationship is：D-d<d1<D-d/4.Just because of the coil 20 of compression spring 100 of the present utility model, bracing ring 10 and The setting of size between line footpath so that when compression spring 100 is compressed, the deformation range of its coil 20 without departing from The external diameter of bracing ring 10, then the deformation range of compression spring 100 meet the fit-up gap of product, the normal dress of product will not be hindered Match somebody with somebody and use.The problem of improving the installation accuracy in limited installing space.And the design of such structure proportion, make Compression spring 100 is obtained while possessing elastic force, possesses required rigidity requirement.The knot of compression spring 100 of the present utility model Structure is simple, and structure proportion is reasonable in design, practical and effectively increase assembling accuracy.

Above disclosed is only preferred embodiment of the present utility model, certainly can not be new to limit this practicality with this The interest field of type, therefore the equivalent variations made according to present utility model application the scope of the claims, still belong to the utility model and covered Scope.
