Implementation

In order to make the purpose, technical solutions and advantages of the utility model clearer, the implementation of the utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, the anti-violent force writing pen of an embodiment includes a refill assembly 10 and a shell 20 sleeved outside the refill assembly 10, and one end of the refill assembly 10 is provided with a refill head for writing 11. One end of the casing 20 is provided with a through hole 201 matching with the refill head 11 .

The outer periphery of the refill assembly 10 is provided with a first buckle portion 12, and the inside of the housing 20 is provided with a second buckle portion 22 matching the first buckle portion 12. When the refill head 11 writes normally, the refill head 11 penetrates The through hole 201 is exposed outside, and the first buckle part 12 abuts against the second buckle part 22. When the refill head 11 is writing vigorously, the first buckle part 12 and the second buckle part 22 slide relatively, thereby The refill assembly 10 slides relative to the casing 20, and the refill head 11 retracts into the casing 20. At this time, the refill head 11 cannot write normally.

Compared with traditional pens, when writing with great force, the first buckle part 12 and the second buckle part 22 slide relatively, so that the refill assembly 10 slides relative to the casing 20, and the refill head 11 is retracted in the shell 20, and now the pen core head 11 cannot write normally, thereby avoiding the occurrence of the situation of writing vigorously.

Referring to the drawings, in this embodiment, the other end of the refill assembly 10 is provided with a pressing cap 13 , and the other end of the housing 20 is provided with a second through hole 202 matching the pressing cap 13 .

The pressing cap 13 passes through the second through hole 202 and is exposed outside. After the refill head 11 is retracted into the casing 20, the user can press the pressing cap 13 to make the first buckle part 12 and the second buckle part 22 slide in reverse, Thus, the refill assembly 10 slides in reverse relative to the casing 20 , and the refill head 11 protrudes out of the casing 20 , so that the refill head 11 is reset.

In other embodiments, a through groove extending vertically may also be provided on the side of the casing 20, and a pressing piece is arranged on the side of the refill assembly 10, and the pressing piece is exposed outside after passing through the through groove, and the pressing piece is passed along the through groove. Movement, thereby realizing the reset of the pen core head 11.

Specifically, in this embodiment, the housing 20 includes a body 220 and a buckle 240, the buckle 240 is disposed between the refill assembly 10 and the body 220, and the second buckle part 22 is disposed inside the buckle 240 .

In other embodiments, it is also possible not to provide a separate buckle 240 , and it is sufficient to directly set the second buckle portion 22 inside the body 220 .

Referring to FIG. 3 and FIG. 4 , in this embodiment, both the first buckle portion 12 and the second buckle portion 22 are protrusions.

Referring to FIG. 3 , in this embodiment, the side of the first buckle part 12 close to the housing 20 is a slope or a curved surface, so that the cross-sectional area of the first buckle part 12 in the axial direction of the refill assembly 10 gradually increases from top to bottom. decrease.

In other embodiments, the side of the first locking portion 12 close to the housing 20 may also be a curved surface, as long as the cross-sectional area of the first locking portion 12 in the axial direction of the pen core assembly 10 can be gradually reduced from top to bottom. Small can be.

The cross-sectional area of the first locking portion 12 in the axial direction of the refill assembly 10 decreases gradually from top to bottom, so that the resetting of the refill head 11 receives less resistance, which facilitates the resetting of the refill head 11 .

3, in this embodiment, the upper end of the first buckle part 12 forms a platform 122, and the refill head 11 is exposed after passing through the through hole 201, and when the refill head 11 writes normally, the platform 122 and the second buckle part 22 abutments.

The upper end of the first buckle part 12 forms a platform 122, which can ensure that when the refill head 11 writes normally, there is enough force between the abutting platform 122 and the second buckle part 22 to prevent the refill assembly 10 from moving against the shell 20. Swipe to ensure that users can write normally when they are not writing too hard.

Referring to FIG. 4 , in this embodiment, the side of the first locking portion 12 close to the refill assembly 10 is a convex curved surface.

The side of the first buckle part 12 close to the refill assembly 10 is a convex curved surface, and the upper end of the first buckle part 12 forms a platform 122, which not only ensures sufficient force between the abutting platform 122 and the second buckle part 22 To prevent the refill assembly 10 from sliding relative to the casing 20, and to allow the refill assembly 10 to slide relative to the casing 20 when the user is writing vigorously.

Specifically, in this embodiment, both the first buckle portion 12 and the second buckle portion 22 are ring-shaped.

Referring to the drawings, in this embodiment, a first guide portion 14 is provided on the outer periphery of the refill assembly 10 , and a second guide portion 24 matching the first guide portion 14 is provided on the inner side of the buckle 240 .

The first guide part 14 cooperates with the second guide part 24 to guide the sliding of the refill assembly 10 relative to the housing 20 .

Specifically, referring to the accompanying drawings, in this embodiment, the first guide part 14 is a groove extending along the vertical direction, and the second guide part 24 is a bump, which snaps into the groove and moves along the groove. Sliding, when the protrusion slides to one end of the groove, it cannot continue to slide, so as to play a limiting role.

In other embodiments, the second guide part 24 can also be set as a groove extending along the vertical direction and has two ends, the first guide part 14 is set as a bump, and the bump is snapped into the groove and along the The groove slides, and when the protrusion slides to one end of the groove, it cannot continue to slide, thereby playing a limiting role.

With reference to the drawings, in this embodiment, the anti-force writing pen further includes an elastic member 30 , and the elastic member 30 is arranged between the refill assembly 10 and the casing 20 .

Specifically, the elastic member 30 is in an elastically compressed state, and the elastic member 30 elastically contacts the refill assembly 10 and the casing 20 respectively, so that the refill assembly 10 can slide relative to the casing 20, so that the refill head 11 retracts into the casing Trend within 20.

Such a setting makes the user experience better when the anti-vigorous writing pen of this embodiment is used.

Specifically, in this embodiment, the elastic member 30 is a spring sleeved outside the refill assembly 10 .

The above-mentioned embodiments only express several embodiments of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as limiting the patent scope of the present utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the scope of protection of the utility model patent should be based on the appended claims.
