Abstract
Description
Technical Field
[0001] The utility model relates to a pen. Background Art
[0002] A pen is a basic writing tool. It usually includes a refill and a shell. When writing, the tip of the refill passes through the nib hole of the shell and is exposed. In order to facilitate use and assembly, the tip is often slightly smaller than the nib hole, so that the tip of the refill can pass through the nib hole smoothly and the tip and the nib hole can fit roughly.
[0003] However, due to reasons such as processing accuracy, the nib of the pen core is often much smaller than the nib hole. This means that after the nib passes through the nib hole, a certain gap is formed between the nib and the nib hole, causing the nib to hit up and down when writing, affecting writing. Utility Model Content
[0004] Based on this, it is necessary to provide a pen that can solve the above problems.
[0005] A pen comprises a pen core, a shell sleeved outside the pen core, and an elastic structure arranged between the pen core and the shell;
[0006] The pen core has a nib for writing, and one end of the shell is provided with a nib hole matching the nib. When the nib passes through the nib hole and is exposed outside, the elastic structure elastically abuts against the pen core, so that the nib abuts against the side wall of the nib hole.
[0007] In one embodiment, the resilient structure is disposed within the housing.
[0008] In one embodiment, one end of the elastic structure is connected to the inner wall of the shell, the other end of the elastic structure is used to elastically abut against the pen core, and a gap is formed between the other end of the elastic structure and the inner wall of the shell.
[0009] In one embodiment, the elastic structure is in the shape of a strip or a sheet.
[0010] In one embodiment, a protrusion is provided at the other end of the elastic structure close to one end of the pen core.
[0011] In one embodiment, the elastic structure is arranged in a region of the housing close to the pen tip hole.
[0012] In one embodiment, one end of the elastic structure is connected to the side wall of the pen tip hole, and the other end of the elastic structure extends upward, so that the length direction of the elastic structure is parallel to the axial direction of the shell.
[0013] In one embodiment, the elastic structure is a plastic part, and one end of the elastic structure is integrally formed with the housing.
[0014] In one embodiment, the housing includes a detachably connected pen tip housing and a pen barrel housing, and one end of the elastic structure is integrally formed with the pen tip housing.
[0015] In one embodiment, the elastic structure is a spring, a spring or a torsion spring.
[0016] When the pen is in use, when the pen tip passes through the pen tip hole and is exposed outside, the elastic structure elastically abuts against the pen core, so that the pen tip abuts against the side wall of the pen tip hole, so that the pen tip does not collide up and down when writing, thereby avoiding affecting normal writing.
[0017] Compared with a traditional pen in which a certain gap is formed between the pen tip and the pen tip hole, when this pen is in use, even if there is a gap between the pen tip and the pen tip hole, the elastic structure elastically abuts against the pen core, so that the pen tip abuts against the side wall of the pen tip hole, thereby avoiding the pen tip from colliding up and down when writing, thereby not affecting writing.

[0022] In order to make the purpose, technical solution and advantages of the present utility model clearer, the implementation mode of the present utility model will be further described below in conjunction with the accompanying drawings.
[0023] Combination Figure 1 , Figure 2 and Figure 3 The utility model discloses a pen of one embodiment, comprising a pen core 10, a shell 20 sleeved outside the pen core 10, and an elastic structure 30 arranged between the pen core 10 and the shell 20.
[0024] The pen core 10 has a pen head 12 for writing, and one end of the housing 20 is provided with a pen tip hole 201 matching the pen head 12 .
[0025] Combination Figure 4 When the pen tip 12 passes through the pen tip hole 201 and is exposed outside, the elastic structure 30 elastically abuts against the pen core 10 , so that the pen tip 12 abuts against the side wall of the pen tip hole 201 .
[0026] When this pen is in use, when the nib 12 passes through the nib hole 201 and is exposed outside, the elastic structure 30 elastically abuts against the pen core 10, so that the nib 12 abuts against the side wall of the nib hole 201, so that the nib will not collide up and down when writing, thereby avoiding affecting normal writing.
[0027] Compared with a traditional pen in which a certain gap is formed between the nib and the pen tip hole, when this pen is in use, even if there is a gap between the nib 12 and the pen tip hole 201, the elastic structure 30 elastically abuts against the pen core 10, so that the nib 12 abuts against the side wall of the pen tip hole 201, avoiding the nib 12 from hitting up and down when writing, thereby not affecting the writing.
[0028] With reference to the drawings, in this embodiment, the elastic structure 30 is disposed inside the housing 20 .
[0029] Preferably, in this embodiment, one end of the elastic structure 30 is connected to the inner wall of the shell 20 , and the other end of the elastic structure 30 is used to elastically abut the refill 10 , and a gap 202 is formed between the other end of the elastic structure 30 and the inner wall of the shell 20 .
[0030] A gap 202 is formed between the other end of the elastic structure 30 and the inner wall of the housing 20 , which can ensure that the elastic structure 30 has a deformation space.
[0031] Specifically, in this embodiment, the elastic structure 30 is in a strip shape. In other embodiments, the elastic structure 30 may also be in a sheet shape.
[0032] With reference to the accompanying drawings, in this embodiment, a protrusion 32 is provided at the other end of the elastic structure 30 close to the end of the pen core 10 .
[0033] The protrusion 32 can better achieve elastic contact between the elastic structure 30 and the pen core 10 .
[0034] Preferably, in this embodiment, the elastic structure 30 is disposed in a region of the housing 20 close to the pen tip hole 201 .
[0035] The elastic structure 30 is disposed in a region of the housing 20 close to the pen tip hole 201 , so that the elastic structure 30 can better elastically abut against the pen core 10 , so that the pen tip 12 abuts against the side wall of the pen tip hole 201 .
[0036] In conjunction with the drawings, specifically, in this embodiment, one end of the elastic structure 30 is connected to the side wall of the pen tip hole 201, and the other end of the elastic structure 30 extends upward, so that the length direction of the elastic structure 30 is parallel to the axial direction of the shell 20.
[0037] Specifically, since the housing 20 forms an inclined surface near the pen tip hole 201 , the other end of the elastic structure 30 extends upward, and a gap 202 is formed between the other end of the elastic structure 30 and the inner wall of the housing 20 .
[0038] Preferably, in this embodiment, the elastic structure 30 is a plastic part, and one end of the elastic structure 30 is integrally formed with the housing 20 .
[0039] The elastic structure 30 is a plastic part, and one end of the elastic structure 30 is integrally formed with the housing 20 , so that it is easy to process.
[0040] Specifically, in the present embodiment, the housing 20 includes a detachably connected pen tip housing 22 and a pen barrel housing (not marked in the figure), and one end of the elastic structure 30 is integrally formed with the pen tip housing 22 .
[0041] In other embodiments, the housing 20 may also include a detachably connected pen barrel housing and a pen tail housing, or other types of structures.
[0042] In other embodiments, the elastic structure 30 may also be an elastic member such as a spring, a spring sheet or a torsion spring.
[0043] As long as the elastic structure 30 can abut against the pen core 10 , so that the pen tip 12 abuts against the side wall of the pen tip hole 201 , it will be sufficient.
[0044] The above-mentioned embodiments only express several embodiments of the present utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present utility model, which all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be based on the attached claims.
