Description
Technical field
It the utility model is related to spring technical field, and in particular to one kind interconnection spring.
Background technology
Spring be it is a kind of utilize elasticity come work machine components.Part is sent out under external force made of elastic material
Raw deformation, restores to the original state again after removing external force.Also " spring " is made.Generally it is made of spring steel.The species complexity of spring is various, presses
Shape point, mainly there is helical spring, scroll spring, flat spring, heterotypic spring etc., but these springs are mostly used aloned, single
It is poor using elastic effect, it is impossible to use to be connected with other springs, multiple user's elasticity reduce, and connection is unstable.
The content of the invention
The purpose of this utility model is to be directed to above-mentioned deficiency of the prior art, there is provided one kind interconnection spring, is provided with more
The elastic joint part of side shape, makes the connection between spring and spring more stable, and elasticity is more preferable.
The purpose of this utility model is achieved through the following technical solutions：
One kind interconnection spring, including spring body, spring body generally helical structure, the spring body are included from upper
Sequentially connected first elastic portion, elastic joint part and the second elastic portion under, elastic joint part are in polygon.
Wherein, the polygon is pentagon or hexagon.
Wherein, the radius of spin of first elastic portion increases successively from top to bottom.
Wherein, first elastic portion is less than the spiral of elastic joint part inscribe circle close to the radius of spin of elastic joint part
Radius.
Wherein, the radius of spin of second elastic portion is reduced successively from top to bottom.
Wherein, second elastic portion is less than the spiral of elastic joint part inscribe circle close to the radius of spin of elastic joint part
Radius.
Wherein, the helical angle of first elastic portion is more than the helical angle of elastic joint part.
Wherein, the helical angle of second elastic portion is more than the helical angle of elastic joint part.
Wherein, the spring body surface is equipped with protective layer.
The beneficial effects of the utility model：A kind of interconnection spring of the utility model, is provided with the elastic connection of polygon
Portion, makes the connection between spring and spring more stable, and elasticity is more preferable.
Brief description of the drawings
Utility model is described further using attached drawing, but the embodiment in attached drawing does not form and the utility model is appointed
What is limited, without creative efforts, can also be according to the following drawings for those of ordinary skill in the art
Obtain other attached drawings.
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the overlooking the structure diagram of the utility model.
Reference numeral includes：Spring body 1, the first elastic portion 2, elastic joint part 3, the second elastic portion 4.
Embodiment
With the following Examples and attached drawing is further described the utility model.
As depicted in figs. 1 and 2, a kind of interconnection spring, including spring body 1, the generally helical structure of spring body 1, institute
Stating spring body 1 includes sequentially connected first elastic portion 2,3 and second elastic portion 4 of elastic joint part from top to bottom, and elasticity is even
Socket part 3 is in polygon.A kind of interconnection spring of the utility model, is provided with the elastic joint part 3 of polygon, makes spring and spring
Between connection it is more stable, elasticity is more preferable.
The polygon of the utility model is pentagon or hexagon.Traditional generally circular configuration of spring body 1, two
Or multiple spring bodies 1 are insecure when linking together, easily loosen, during using polygon, by increasing capacitance it is possible to increase the contact point of connection,
Make connection more firm.Preferably, polygon is hexagon.
The radius of spin of first elastic portion 2 of the utility model increases successively from top to bottom.First elastic portion 2 is spring sheet
The structure of the top of body 1, when use, contact at first with contact surface, and provide elastic force at first, and user can feel
First time elastic force.First elastic portion 2 is less than spiral the half of 3 inscribe circle of elastic joint part close to the radius of spin of elastic joint part 3
Footpath.First elastic portion 2 in compression, shrink and close to elastic joint part 3 by the first elastic portion 2, since the radius of spin is small, first
Elastic portion 2 is not in contact with rubbing with elastic joint part 3, and sound is few during compression, and similarly it is few to spring back also sound for the first elastic portion 2, makes
Used time peace and quiet are noiseless.
The radius of spin of second elastic portion 4 of the utility model is reduced successively from top to bottom.The interconnection bullet of the utility model
Spring is is symmetrical arranged, and the first elastic portion 2 is identical with 4 structure of the second elastic portion, is symmetrical arranged, using the teaching of the invention it is possible to provide soft spring.The
Two elastic portions 4 are less than the radius of spin of 3 inscribe circle of elastic joint part close to the radius of spin of elastic joint part 3.Second elastic portion 4
The whole radius of spin be respectively less than the radius of spin of 3 inscribe circle of elastic joint part, the second elastic portion 4 is in compression, the second elasticity
Portion 413 is shunk to elastic joint part 3 contact friction with elastic joint part 3, and sound is few during compression, similarly sound during rebound
Less, it is very quiet during use.
The helical angle of first elastic portion 2 of the utility model is more than the helical angle of elastic joint part 3.Second elastic portion 4
Helical angle is more than the helical angle of elastic joint part 3.Helical angle is bigger, and elasticity is weaker, and contact use feels better, the first elastic portion
2 be the structure of 1 the top of spring body, and when use contacts at first with user, using the teaching of the invention it is possible to provide the elastic sensation of user's softness, together
When the second elastic portion 4 active force of secondary rebound is provided for user, the two structure makes the elasticity of Monolithic spring body 11 more preferable,
Spring level is more rich, and use is more comfortable.
1 surface of spring body of the utility model is equipped with electro-cladding.Spring body 1 is metal material, usage time
Get rusty easily long, electro-cladding is arranged at the outer surface of spring body 1, spring body 1 is completely cut off with external environment, avoids bullet
Spring body 1 is aoxidized, and increases the service life of spring body 1.
Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality
With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general
Lead to it will be appreciated by the skilled person that can be to the technical solution of the utility model technical scheme is modified or replaced equivalently, without departing from this
The spirit and scope of utility model technical solution.
