Abstract
The utility model relates to a single line button head nib spring, including installation department and elasticity portion, installation department and elasticity portion are for the helical structure who forms by the wire spiral winding, and the elasticity portion is kept away from one of installation department and is served the conflict portion that has the single wire of being buckled by elasticity portion and form, the conflict portion coincides mutually with the central line of elasticity portion, and the top end face of conflict portion and ball contact is planar structure. The utility model provides a conflict portion is bent by the terminal single wire of elasticity portion and is formed, not only need not the process of bending, can effectively reduce the material quantity moreover, greatly reduced manufacturing cost, in addition, conflict portion is planar structure with the top terminal surface of ball contact, and the ball is the point contact with contact site terminal surface, writes more in the same direction as smooth, and it is more convenient to assemble.
Description
Technical Field
The utility model relates to a spring technical field, concretely relates to single line button head nib spring.
Background
In the prior art, pen points of ball pens, gel pens and the like are all composed of a ball seat body, a ball and a spring, and a contact part at the top of the spring is abutted against the ball. The contact portion of the top of the existing spring is an arc-shaped structure formed by bending a metal wire into two strands, such as a parallel round-head nib spring disclosed in the application No. 2018202080502 of the present company. The nib spring of this structure has found many problems in practice, and improvement is desired. If the conflict portion is formed by bending two strands of metal wires, the material consumption is increased, the bending procedure is added, and the production cost is greatly improved. Moreover, due to the structural characteristics, the ball is inconvenient to assemble, the writing is not smooth enough, and abnormal sound is often generated.
SUMMERY OF THE UTILITY MODEL
To the not enough in the background art, the utility model provides a single line button head nib spring.
The utility model adopts the technical proposal that: the utility model provides a single line button head nib spring, includes installation department and elasticity portion, installation department and elasticity portion are the helical structure who forms by the wire spiral winding, elasticity portion keeps away from one of installation department and serves and have the conflict portion that is buckled and forms by the single wire of elasticity portion, conflict portion coincides mutually with the central line of elasticity portion, and conflict portion and the top end face of ball contact are planar structure.
Further, conflict portion, installation department and elastic component connect the structure for integrated into one piece.
Furthermore, the periphery of the top end face of the contact part contacting with the ball is provided with an arc-shaped step.
Further, the height of the arc-shaped step is less than 1/4 of the radius of the ball.
Furthermore, the elastic part comprises a cylindrical section and a conical section, the abutting part is arranged at one end, away from the elastic part, of the conical section, and the diameter of the conical section is gradually reduced from the cylindrical section to the abutting part.
Further, the diameter of the mounting portion is larger than that of the elastic portion.
The utility model has the advantages that: the utility model provides a conflict portion is bent by the terminal single wire of elasticity portion and is formed, not only need not the process of bending, can effectively reduce the material quantity moreover, greatly reduced manufacturing cost, in addition, conflict portion is planar structure with the top terminal surface of ball contact, and the ball is the point contact with contact site terminal surface, writes more in the same direction as smooth, and it is more convenient to assemble.
In addition to the above-described objects, features and advantages, the present invention has other objects, features and advantages.
The present invention will be described in further detail below with reference to the accompanying drawings.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a perspective view of the present invention.
Fig. 3 is a schematic structural view of the interference portion having the arc-shaped step.
In FIGS. 1-3: 1. an installation part; 2. an elastic portion; 3. a contact part; 4. an arc-shaped step; 5. a cylindrical section; 6. a tapered section.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.
The utility model provides a single line button head nib spring.
In this embodiment, referring to fig. 1-3, this single line button head nib spring, including installation department 1 and elastic component 2, installation department and elastic component are the helical structure who forms by wire spiral winding, the elastic component is kept away from one of installation department and is served and have conflict portion 3 that is buckled and form by the single wire of elastic component, conflict portion coincides mutually with the central line of elastic component, and the top end face of conflict portion and ball contact is planar structure.
The utility model provides a conflict portion is bent by the terminal single wire of elasticity portion and is formed, not only need not the process of bending, can effectively reduce the material quantity moreover, greatly reduced manufacturing cost, in addition, conflict portion is planar structure with the top terminal surface of ball contact, and the ball is the point contact with contact site terminal surface, writes more in the same direction as smooth, and it is more convenient to assemble.
Specifically, the abutting part, the mounting part and the elastic part are of an integrally formed connecting structure;
example 2: the periphery of the top end face of the contact part contacting with the ball is provided with an arc-shaped step 4. The arc-shaped step surrounds the ball, so that the ball is not easy to jack and is more smooth to write. The height of the arc-shaped step is 1/4 less than the radius of the ball; the elastic part consists of a cylindrical section 5 and a conical section 6, the abutting part is arranged at one end of the conical section far away from the elastic part, and the diameter of the conical section is gradually reduced from the cylindrical section to the abutting part; the diameter of the mounting portion is greater than the diameter of the elastic portion. Through setting up the toper section, have to follow good elasticity bearing effect to the ball, it is more smooth and easy to know.
The skilled person should understand that: although the present invention has been described in accordance with the above embodiments, the inventive concept is not limited to this embodiment, and any modification of the inventive concept will be included in the scope of the patent claims.
