Abstract

The utility model discloses a writing pen with an LED lamp. The writing pen comprises a pen refill, a pen cylinder and a tail cap, wherein the pen refill is arranged inside the pen cylinder in a slidable manner, a thrust spring is connected between the pen refill and the pen cylinder, a lamp source assembly is arranged inside the pen cylinder in a slidable manner and arranged on the pen refill, the tail cap is arranged on the pen cylinder in a detachable manner, and a light source is fixed on the tail cap and comprises a first electrode and a second electrode, with the first electrode connected to the lamp source assembly and the second electrode arranged on the lamp source assembly. Operation of the lamp source assembly is controlled by writing states of the pen refill, and no independent operating elements are needed to control the operation of the lamp source assembly, thereby reducing cost and making operation much simpler. The tail cap can be taken down when luminance from outside is sufficient, thus to reduce energy consumption.

Description

A kind of writing pen with the LED lamp

Technical field

The utility model relates to a kind of stationery, relates in particular to a kind of writing pen with the LED lamp.

Background technology

Lettering pen is a kind of writing implement indispensable in studying and living.Because the use of lettering pen must guarantee that extraneous light reaches certain intensity, otherwise can injure eyes or writing effect is not good.Due to the impact of the factors such as power failure, lettering pen has been subject to certain restriction in the use at night.Disclosing some in prior art adopts the LED lamp to improve luminous intensity to increase the range of application of lettering pen.This writing pen comprises pen container and pen core, and described circuit control device need to be controlled the break-make work of LED lamp as required, thus the independently executive component such as button need to be set, so complex structure, cost is higher.Between this, prior art has necessity of further improvement.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of writing pen with the LED lamp, can realize the simple to operate of the break-makes such as LED, and need not to arrange independently button member, and is with low cost.

For solving the problems of the technologies described above, the utility model adopts following technical proposals.

A kind of writing pen with the LED lamp comprises pen core, pen container and tail-hood, it is characterized in that,

Wherein, described pen core is slidably disposed in described pen container, and a thrust spring is connected between described pen core and pen container; Be provided with slidably the lamp source component in described pen container, described lamp source component is positioned at the top of described pen core; Described tail-hood is removably disposed on described pen container, is fixed with power supply on described tail-hood, and described power supply comprises the first electrode and the second electrode, and described the first electrode is connected to described lamp source component, and described the second electrode is positioned at the top of described lamp source component.

Adopt the utility model of technique scheme, when writing, pen core is subject to External Force Acting can move up and promote described lamp source component, makes described lamp source component touch described the second electrode, and then making lamp source component energising work, the light of lamp source component penetrates from pen container.When stopping writing, described pen core breaks away from described lamp source component under the effect of thrust spring.

In this writing pen with the LED lamp of the present utility model, described lamp source component comprises LED lamp and flexure strip, and being provided with in described pen container can be for the through hole of described LED lamp slip, and the length of described flexure strip is greater than the diameter of described through hole.In this preferred version, described flexure strip defines the distance that described LED lamp moves down, and prevents that described lamp source component from coming off in described pen container, has guaranteed the reliability of this writing pen with the LED lamp of the present utility model.

Implement this writing pen with the LED lamp of the present utility model, have following beneficial effect: the work of described lamp source component is controlled by the state of writing of pen core, need not to adopt the independently work of executive component control lamp source component, reduced cost, make operation more simple.When extraneous sufficient brightness is enough, take off described tail-hood, can reduce energy consumption.

Description of drawings

Fig. 1 is the schematic diagram of this writing pen with the LED lamp of the present utility model;

Fig. 2 is the cutaway view of Fig. 1;

Fig. 3 is the partial view at the A place of Fig. 2, has represented another kind of use state of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

Of the present utility model this writing pen with the LED lamp referring to figs. 1 through shown in Figure 3 comprises pen core 2, pen container 1 and tail-hood 3.

Wherein, described pen core 2 is slidably disposed in described pen container 1, and a thrust spring 4 is connected between described pen core 2 and pen container 1; Be provided with slidably lamp source component 5 in described pen container 1, described lamp source component 5 is positioned at the top of described pen core 2; Described tail-hood 3 is removably disposed on described pen container 1, be fixed with power supply 6 on described tail-hood 1, described power supply 6 comprises the first electrode 601 and the second electrode 602, and described the first electrode 601 is connected to described lamp source component 5, and described the second electrode 602 is positioned at the top of described lamp source component 5.

In the present embodiment, described pen container is provided with a plurality of holes 101 that supply the light ejaculation of described LED lamp source component 5.But also described pen container 1 can be arranged to transparence, for beam projecting.

In this writing pen with the LED lamp of the present utility model, described lamp source component 5 comprises LED lamp 501 and flexure strip 502, and being provided with in described pen container 1 can be for the through hole of described LED lamp 501 slips, and the length of described flexure strip 502 is greater than the diameter of described through hole.In this preferred version, described flexure strip 502 defines the distance that described LED lamp 501 moves down, and prevents that described lamp source component 5 from coming off in described pen container 1, has guaranteed this writing pen reliability in use with the LED lamp of the present utility model.

Claims

1. the writing pen with the LED lamp, comprise pen core, pen container and tail-hood, it is characterized in that,

2. the writing pen with the LED lamp according to claim 1, is characterized in that, described lamp source component comprises LED lamp and flexure strip, and being provided with in described pen container can be for the through hole of described LED lamp slip, and the length of described flexure strip is greater than the diameter of described through hole.
