Description

A new type of drop-resistant pen

technical field

The utility model relates to a writing pen, in particular to a novel drop-resistant pen capable of protecting the pen core.

Background technique

At present, the structure of the anti-fall pens on the market mainly includes the end of the pen tube with weight, the protective structure, and the pressure plate type. The reliability of the anti-drop function at the end of the heavy pen tube is not very good, and the landing rate of the tail of the pen tube cannot be guaranteed to be 100%. Adding a protective structure makes the pen structure redundant and inconvenient to use; the pressure plate type pen posture is fixed, which is easy to cause Tired hands.

Utility model content

In order to solve the above technical problems, the utility model provides a novel anti-drop pen.

Its technical solutions are:

A new type of drop-resistant pen, including a pen tube and a pen core, a spring is set outside the head of the pen core, an opening is provided at the end of the pen tube, a slider is provided inside the pen tube, and a slider is provided inside the slider A refill fixing hole is provided, and a button for controlling the sliding of the slider is arranged on the surface of the slider, and the button is arranged in the opening; one end of the spring is fixed inside the end of the pen tube, and the other end of the spring is fixed on the slider.

An inclined chute is arranged on the slider, and the button is a wedge-shaped body adapted to the inclined chute. Anti-separation baffles are arranged at both ends of the wedge-shaped body, and an anti-slip rubber layer is arranged on the surface of the wedge-shaped body.

The beneficial technical effect of the utility model is:

The utility model provides a new type of anti-drop pen. When in use, hold the button with your fingers, and the pen core will extend out of the pen tube, and you can write normally at this time; The pen tip can be retracted into the pen tube without breaking, so that the pen tip is protected by the pen tube, and the anti-drop function is realized.

Detailed ways

The utility model provides a new anti-drop pen. In order to make the purpose, technical solution and advantages of the utility model clearer and clearer, the utility model will be further described in detail in conjunction with the accompanying drawings and embodiments below.

The utility model provides a novel anti-drop pen, which realizes the anti-drop function by automatically retracting the tip of the pen.

In conjunction with the accompanying drawings, a new type of drop-resistant pen includes a pen tube 1, a cylindrical slider 2 is arranged inside the pen tube 1, three strip-shaped openings 3 are arranged at equal intervals on the pen tube, and the strip-shaped openings 3 are embedded Button 4 is arranged, and button 4 is set to wedge-shaped body, and spring 5 is provided with at pen tube front end.

The slider 2 is provided with three equally spaced inclined chute 6 , and the width of the slanted chute 6 is adapted to the width of the button 4 . The center of the slider is provided with a refill fixing hole 7 for the refill 10 to pass through and be fixed.

The front and rear ends of the above-mentioned button 4 are provided with protruding anti-separation baffles 8 to prevent the button 4 from detaching from the pen barrel. An anti-slip rubber layer 9 is arranged on the top surface of the button 4 .

One end of the above-mentioned spring is against the inner side of the end of the pen tube, and the other end of the above-mentioned spring is against the slide block.

The using method of the present utility model is briefly described below:

When writing, hold the pen tube 1 with your hand, and pinch the anti-slip rubber layer 9 on the surface of the button 4 with your fingers to make the button 4 move to the inside of the pen tube. At the same time, the button 4 will slide relative to the inclined chute 6, so that the slide Block 2 drives the pen core 10 to move forward, so that the nib stretches out of the pen tube to realize the writing function. Simultaneously, the spring 5 compresses and stores energy. When the pen is separated from the hand, the pressure on the button 4 disappears, and the slider 2 moves backward together with the refill 10 under the action of the spring 5, so that the pen tip automatically retracts into the pen tube 1, avoiding the pen tip caused by falling. damage, to achieve the function of anti-fall.

It should be noted that, under the guidance of this specification, any equivalent replacement or obvious modification made by those skilled in the art shall fall within the protection scope of the present utility model.
