Abstract
The utility model provides a kind of doubling round end pen tip spring, including being assemblied in the intracorporal elastic component of ball seat, described elastic component one end is equipped with and abuts with ball and the abutting part of frictional fit, abutting part has contact surface, the contact surface is cambered surface, and the contact surface is abutted with ball elasticity and frictional fit between contact surface and ball.The cambered surface is convex globoidal, and the contact surface of the abutting part is hemispherical protuberances structure.By the way that the contact surface of spring is designed as arcwall face, friction becomes smaller this product when contacting contact surface with ball, prevents abutting part from shifting, very useful when avoiding written oil leak and writing the problem of Caton, abnormal sound.
Description
Technical field
The utility model relates to spring, in particular to a kind of doubling round end pen tip spring.
Background technique
Currently, the nib of ball pen, gel ink pen etc. is all to have ball seat body, ball and spring to constitute, traditional spring and ball
The contact surface of pearl be plane, ball roll when, due to contact surface be planar structure, ball roll when with contact surface friction compared with
Greatly, the contact surface of spring is easy to be staggered with ball, leads to written oil leak, when writing the problems such as Caton, abnormal sound, so needing one kind
Doubling round end pen tip spring just can solve this problem.
Utility model content
Aiming at the shortcomings of the prior art, the utility model provides a kind of doubling round end pen tip spring.
To achieve the goals above, technical solution adopted in the utility model is: a kind of doubling round end pen tip spring, packet
It includes and is assemblied in the intracorporal elastic component of ball seat, described elastic component one end is equipped with and abuts with ball and the abutting part of frictional fit, supports
Socket part has a contact surface, and the contact surface is cambered surface, the contact surface abutted with ball elasticity and contact surface and ball it
Between frictional fit.
The cambered surface is convex globoidal, and the contact surface of the abutting part is hemispherical protuberances structure.
The cambered surface is cancave cambered surface, and the contact surface of the abutting part is hemispherical groove structure.
The abutting part is cylindrical-shaped structure, and the convex globoidal is that abutting part bending is formed.
The elastic component is spring, and spring includes mounting portion, elastic portion and abutting part, the mounting portion, elastic portion
It is an integral structure with abutting part, mounting portion and elastic portion are that wire is wound to helicoidal structure.
The spring is made of stainless steel material.
The utility model has the beneficial effects that the utility model provides a kind of doubling round end pen tip spring, this product pass through by
The contact surface of spring is designed as arcwall face, and friction becomes smaller when contacting contact surface with ball, prevents abutting part from shifting, avoids
Written oil leak and when writing the problem of Caton, abnormal sound, it is very useful.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of doubling round end pen tip spring, including it is assemblied in the intracorporal elastic component of ball seat, the elasticity
100 one end of part is equipped with and abuts with ball and the abutting part 110 of frictional fit, and with contact surface 111, described connects abutting part 110
Contacting surface 111 is cambered surface, and the contact surface 111 is abutted with ball elasticity and frictional fit between contact surface 111 and ball, passes through
Change the structure of contact surface to change the coefficient of friction of contact surface and ball, to achieve the purpose that prevent abutting part from deviating.
The cambered surface is convex globoidal, and the contact surface 111 of the abutting part 110 is hemispherical protuberances structure, convex globoidal
Small with the contact area of ball, coefficient of friction is small, it is not easy to the problem of deviating.
The abutting part 110 is cylindrical-shaped structure, and the convex globoidal is that 110 bending of abutting part is formed, bending structure
Simply, cambered surface can be effectively formed.
The elastic component 100 is spring, and spring includes mounting portion 120, elastic portion 130 and abutting part 110, the peace
Dress portion 120, elastic portion 130 and abutting part 110 are an integral structure, and mounting portion 120 and elastic portion 130 are that wire is wound to spiral shell
Shape structure is revolved, it is elastic portion that spring as a whole, which plays elastic reaction,.
The spring is made of stainless steel material, which is SUS 304WPB stainless steel material, has very high
Strength degree and elastic limit, and the performances such as toughness and corrosion resistance of the material are stronger.
Embodiment 2；The present embodiment the difference from embodiment 1 is that, the cambered surface be cancave cambered surface, the abutting part
110 contact surface 111 is hemispherical groove structure, and since spring structure is smaller, cancave cambered surface may be more difficult to process, and it is advantageous to adopt
With the structure in embodiment 1.
The utility model has the beneficial effects that the utility model provides a kind of doubling round end pen tip spring, this product pass through by
The contact surface of spring is designed as arcwall face, and friction becomes smaller when contacting contact surface with ball, prevents abutting part from shifting, avoids
Written oil leak and when writing the problem of Caton, abnormal sound, it is very useful.
