Abstract
The utility model discloses a sealed spring mechanism for a ball-point pen. The sealed spring mechanism comprises a pen holder, a telescopic mechanism and a spring. The sealed spring mechanism is characterized in that the telescopic mechanism and the spring are arranged in the pen holder, a pen plug is arranged at the end of the pen holder, the pen plug and the pen holder form a sealed structure, and the spring is arranged in the sealed structure. The sealed spring mechanism is simple in structure and low in production cost, the telescopic mechanism and the spring are arranged in the pen holder, the spring is hidden in the pen holder through the pen plug, and the spring in the pen holder does not need to be taken out when people replace a pen refill, so that the spring is effectively prevented form falling.
Description
Technical field
The utility model belongs to a tool, is specifically related to a kind of sealed spring mechanism of ball pen.
Background technology
Pen is indispensable instrument during people learn, work, and pen comprises signature pen, propelling pencil, ball pen, pen.Wherein ball pen is divided into again spring ball pen (having rotary type ball pen, push type cylinder pen) and fixed ball pen; for spring ball pen; it is mainly to regulate control pen core flexible in nib by spring; by spring, refill expansion is returned in nib, can protect pen core to avoid being broken because of carelessness.The front end that existing spring ball pen arranges penholder by spring activity as shown in Figure 1, after ink in people use pen core, can be with the pen core renewing, but when people's spring with change-fountain pen core or dismounting time can be removed, the cross section of spring is circular arc, therefore the poor stability of spring, easily rolls and falls earthward, thereby loses spring.The more existing ball pen that prevents that spring from dropping in the market, otherwise their complex structure production cost is high, thus price is more expensive; Or can there is the situation that spring drops.
Utility model content
Goal of the invention of the present utility model is in order to overcome the deficiencies in the prior art, provides a kind of simple in structure, with low cost, and can effectively prevent the sealed spring mechanism of the ball pen that spring drops.
The purpose of this utility model can be achieved through the following technical solutions:
The sealed spring mechanism of ball pen, comprise penholder, telescoping mechanism and spring, it is characterized in that: described telescopic component and spring are arranged in penholder, the end of described penholder is provided with pen plug, pen plug and penholder form sealed construction, and spring is arranged in sealing formula structure.
Further scheme of the present utility model: described penholder is provided with internal thread, and pen plug is provided with external screw thread, penholder and pen plug are spirally connected.
Further scheme of the present utility model: described telescopic component adopts rotary type telescopic component or push type telescopic component.
Further scheme of the present utility model: described telescopic component and spring form telescoping mechanism.
Further scheme of the present utility model: described telescopic component is provided with expansion link, spring housing is located on the expansion link of telescopic component, and described pen plug is provided with circular hole, and the expansion link of telescopic component is through circular hole.
Further scheme of the present utility model: described spring comprises large footpath section and path section, and miner diameter end is against on telescopic component, and bigger diameter end is against in pen plug.
Effective effect of the present utility model: of the present utility model simple in structure, telescopic component and spring are arranged in penholder, by pen plug, will in spring, ensconce in penholder, people need not take out the spring in penholder when with change-fountain pen core, thereby have effectively avoided spring to drop.And low production cost of the present utility model.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Specific embodiment 1:
The sealed spring mechanism of the ball pen as shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, comprise pen plug 1, penholder 2, telescopic component 3 and spring 4, described telescopic component 3 and spring 4 are arranged in penholder 2, telescopic component 3 and spring 4 form telescoping mechanism, telescopic component 3 is fixedly mounted in penholder 2, the end of described penholder 2 is provided with pen plug 1, and pen plug 1 and penholder 2 form sealed construction, and spring 4 is arranged in sealing formula structure.
Described spring 4 comprises large footpath section and path section, and miner diameter end is against on telescopic component 3, and bigger diameter end is against in pen plug 1.
Described penholder 2 is provided with internal thread, and pen plug 1 is provided with external screw thread, and penholder 2 is spirally connected with pen plug 1.
Described telescopic component 3 adopts existing rotary type telescopic component, described telescopic component 3 is provided with expansion link 3-1, and expansion link 3-1 is hollow structure, and spring 4 is set on the expansion link 3-1 of telescopic component 3, described pen plug 1 is provided with circular hole 1-1, and the expansion link 3-1 of telescopic component 3 is through circular hole 1-1.
Adopt ball pen of the present utility model, pen core 5 is sleeved in the expansion link 3-1 of telescopic component 3.
Operation principle of the present utility model: when telescopic component 3 is rotated in a clockwise direction, telescopic component 3 drives expansion link 3-1 reach, when telescopic component 3 rotates in the counterclockwise direction, drives expansion link 3-1 on telescopic component 3 toward travelling backwards by spring 4.
Specific embodiment 2:
Feature of the present utility model is: described telescopic component 3 adopts existing push type telescopic component, and other features are identical with specific embodiment 1.
