Wherein, the screw diameter of the changeover portion is 5.0-6.8 centimetres, and the screw diameter of bottom stage is 5.0-6.8 centimetres.
The utility model has the beneficial effects that a kind of soft or hard combination spring of the utility model, is provided with the small soft bullet of screw pitch
Spring section and the big hard spring section of screw pitch, slinky spring section are located at the upper end of spring body, the slinky spring section that when use contacts at first to
User provides soft sense of touch, and with the compression of spring body, hard spring section provides strong support to user, using
Person experiences soft or hard two kinds of feelings of spring simultaneously, and hardness is variable, has stereovision, and comfort level is high.
Detailed description of the invention
Utility model is described further using attached drawing, but the embodiment in attached drawing does not constitute and appoints to the utility model
What is limited, for those of ordinary skill in the art, without creative efforts, can also be according to the following drawings
Obtain other attached drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is another structural schematic diagram of the utility model.
Appended drawing reference includes: 1, slinky spring section；2, changeover portion；3, hard spring section；4, bottom stage.
Specific embodiment
With the following Examples and attached drawing is further described the utility model.
As depicted in figs. 1 and 2, a kind of soft or hard combination spring of the utility model, including spring body, spring body is from upper
To lower including sequentially connected slinky spring section 1, changeover portion 2, hard spring section 3 and bottom stage 4, the screw diameter of changeover portion 2 is greater than
The screw diameter of slinky spring section 1 and the screw diameter of hard spring section 3, the screw pitch of changeover portion 2 are greater than the screw pitch of slinky spring section 1 and hard
The screw diameter of the screw pitch of spring section 3, the slinky spring section 1 is identical as the screw diameter of hard spring section 3, the spiral shell of hard spring section 3
Away from the screw pitch for being greater than slinky spring section 1.
A kind of soft or hard combination spring of the utility model is provided with the small slinky spring section 1 of screw pitch and the big hard spring of screw pitch
Section 3, slinky spring section 1 are located at the upper end of spring body, and the slinky spring section 1 that when use contacts at first, slinky spring section 1 is mentioned to user
For soft sense of touch, with the compression of spring body, hard spring section 3 provides strong support to user, makes user simultaneously
Soft or hard two kinds of feelings of spring are experienced, hardness is variable, has stereovision, and comfort level is high.Specifically, the utility model is soft
When scleroma conjunction spring is under pressure, slinky spring section 1 is since screw pitch is small, and deformation occurs at first, and soft contact is provided for user
Sense, as spring body continues to compress, also deformation occurs for the larger screw pitch of hard spring section 3, provides strong branch for user
Support makes user while feeling soft or hard two kinds of feelings, and hardness is variable, has stereovision, and comfort level is high.
The screw pitch of the hard spring section 3 of the utility model is 2-8 times of the screw pitch of slinky spring section 1.It is obtained according to many experiments,
The screw pitch of hard spring section 3 is the screw pitch of slinky spring section 1 when being 2-8 times, and user feels that more preferably, hardness is variable, has level
Sense, comfort level are high.Further, the screw pitch of hard spring section 3 is 2.0-4.0 centimetres, and the screw pitch of slinky spring section 1 is 0.5-1.0 centimetres.
Further, the screw pitch of hard spring section 3 is 3 centimetres, and the screw pitch of slinky spring section 1 is 1 centimetre.
The screw diameter of the slinky spring section 1 of the utility model is 3.0-4.5 centimetres, and the screw diameter of hard spring section 3 is
3.0-4.5 centimetre.The screw diameter of slinky spring section 1 is identical as the screw diameter of hard spring section 3, can provide the same place
Soft or hard two different feelings, further, the screw diameter of changeover portion 2 is 5.0-6.8 centimetres, and the screw diameter of bottom stage 4 is
5.0-6.8 centimetre.Further, the screw diameter of changeover portion 2 is 5.0 centimetres to reason, and the screw diameter of bottom stage 4 is 6.8 centimetres.
