Description of the embodiments

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, embodiments of the present utility model will be further described with reference to the accompanying drawings.

The writing pen for preventing a large force according to an embodiment shown in fig. 1 and 2 includes a cartridge assembly 10 and a housing 20 sleeved outside the cartridge assembly 10, wherein one end of the cartridge assembly 10 is provided with a cartridge head 11 for writing, and one end of the housing 20 is provided with a through hole 201 matched with the cartridge head 11.

The periphery of refill subassembly 10 is equipped with first buckle portion 12, the inboard of shell 20 is equipped with the second buckle portion 22 that matches with first buckle portion 12, refill head 11 is when writing normally, refill head 11 exposes outside after penetrating through-hole 201 to first buckle portion 12 and second buckle portion 22 butt, refill head 11 is when writing strongly, first buckle portion 12 and second buckle portion 22 relative slip, thereby make refill subassembly 10 slide for shell 20, refill head 11 is retracted in shell 20, refill head 11 can't write normally this moment.

Compared with a traditional pen, when the writing with high force is performed, the first clamping part 12 and the second clamping part 22 slide relatively, so that the pen refill assembly 10 slides relative to the shell 20, the pen refill head 11 is retracted into the shell 20, and the pen refill head 11 cannot write normally at the moment, so that the condition of writing with high force is avoided.

Referring to the drawings, in the present embodiment, the other end of the cartridge 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.

After the pen refill head 11 is retracted into the housing 20 after the pressing cap 13 penetrates the second through hole 202 and is exposed to the outside, the user can make the first fastening part 12 and the second fastening part 22 slide reversely by pressing the pressing cap 13, so that the pen refill assembly 10 slides reversely relative to the housing 20, and the pen refill head 11 extends out of the housing 20, thereby resetting the pen refill head 11.

In other embodiments, a through groove extending in the vertical direction may be provided in the side surface of the housing 20, a pressing member may be provided in the side surface of the cartridge assembly 10, and the pressing member may be exposed to the outside after passing through the through groove, and the pressing member may be moved along the through groove, thereby resetting the cartridge head 11.

Specifically, in the present embodiment, the housing 20 includes a body 220 and a fastener 240, the fastener 240 is disposed between the cartridge assembly 10 and the body 220, and the second fastener 22 is disposed inside the fastener 240.

In other embodiments, the second engaging portion 22 may be provided directly inside the main body 220 without providing the separate engaging piece 240.

Referring to fig. 3 and 4, in the present embodiment, the first fastening portion 12 and the second fastening portion 22 are both protrusions.

Referring to fig. 3, in the present embodiment, a surface of the first fastening portion 12 near the housing 20 is an inclined surface or a curved surface, so that a cross-sectional area of the first fastening portion 12 in the axial direction of the pen core assembly 10 gradually decreases from top to bottom.

In other embodiments, the surface of the first fastening portion 12 near the housing 20 may be curved, as long as the sectional area of the first fastening portion 12 in the axial direction of the cartridge assembly 10 can be gradually reduced from top to bottom.

The cross-sectional area of the first fastening portion 12 in the axial direction of the cartridge assembly 10 gradually decreases from top to bottom, so that the resistance force applied to the cartridge head 11 during the resetting is small, and the resetting of the cartridge head 11 is facilitated.

Referring to fig. 3, in the present embodiment, the upper end of the first fastening portion 12 forms a platform 122, the refill 11 is exposed to the outside after passing through the through hole 201, and the platform 122 abuts against the second fastening portion 22 when the refill 11 is writing normally.

The platform 122 is formed at the upper end of the first fastening portion 12, so that when the pen refill 11 writes normally, enough force is provided between the abutting platform 122 and the second fastening portion 22 to prevent the pen refill assembly 10 from sliding relative to the housing 20, so as to ensure that a user can write normally when no large force is applied.

Referring to fig. 4, in this embodiment, a surface of the first fastening portion 12 near the pen core assembly 10 is a convex curved surface.

The surface of the first fastening part 12, which is close to the pen core assembly 10, is a convex curved surface, and the upper end of the first fastening part 12 forms a platform 122, so that not only is enough force between the abutting platform 122 and the second fastening part 22 ensured to prevent the pen core assembly 10 from sliding relative to the housing 20, but also the pen core assembly 10 can slide relative to the housing 20 when a user writes with great force.

Specifically, in the present embodiment, the first engaging portion 12 and the second engaging portion 22 are both annular.

Referring to the drawings, in the present embodiment, the outer periphery of the cartridge assembly 10 is further provided with a first guide portion 14, and the inner side of the clip 240 is further provided with a second guide portion 24 that matches the first guide portion 14.

The first guide portion 14 and the second guide portion 24 cooperate to guide the sliding of the cartridge assembly 10 with respect to the housing 20.

Specifically, in the present embodiment, the first guiding portion 14 is a groove extending along the vertical direction, the second guiding portion 24 is a protrusion, and the protrusion is clamped into the groove and slides along the groove, so that the protrusion cannot slide continuously when sliding to one end of the groove, thereby playing a limiting role.

In other embodiments, the second guiding portion 24 may be configured as a groove extending along a vertical direction and having two ends, the first guiding portion 14 is configured as a bump, the bump is clamped into the groove and slides along the groove, and the bump cannot slide continuously when sliding to one end of the groove, thereby playing a limiting role.

In this embodiment, the writing pen for preventing a large force further includes an elastic member 30, and the elastic member 30 is disposed between the cartridge assembly 10 and the housing 20.

Specifically, the elastic member 30 is in an elastically compressed state, and the elastic member 30 elastically abuts against the cartridge assembly 10 and the housing 20, respectively, so that the cartridge assembly 10 has a tendency to slide relative to the housing 20, so that the cartridge head 11 is retracted into the housing 20.

By the arrangement, the user experience is better when the anti-high-force writing pen is used.

Specifically, in the present embodiment, the elastic member 30 is a spring that is fitted over the cartridge assembly 10.

The above embodiments represent only a few embodiments of the present utility model, which are described in more detail and are not to be construed as limiting the scope of the present utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
