[0001] The utility model belongs to the technical field of writing pens, in particular to a writing pen. Background Art

[0002] Writing pens are stationery products that are frequently used in daily life. Most of the areas that can be shaped are on the top, and different shapes on the top attract the attention of consumers. Chinese patent CN214873825U discloses "A decompression fun pen", which drives the shaft to move through a ball bearing, so that the decorative part moves, increases the function of the pen, and can achieve the effect of decompression and relaxation. However, its structure is relatively complex, the processing and assembly costs are high, the shape of the decorative part is fixed, and for a press pen, an external force needs to be applied to the decorative part. The unevenness of the decorative part will cause the user to feel poorly and reduce the user's comfort. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a writing pen, which can increase the aesthetics of the writing pen by changing the elastic shaping body. The elastic shaping body is easy to replace and has high flexibility in use, and the user has good comfort when pressing on the elastic shaping body.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a writing pen, including a pen body with a refill, and a pressing mechanism connected to the refill, a shaping unit is provided on the top of the pen body, and the shaping unit includes a support body and an elastic shaping body connected to the support body, the elastic shaping body cover is provided on the outside of the support body and at least partially forms a hollow cavity, and the support body has a flared surface for at least partially opening the elastic shaping body.

[0005] The utility model provides a shaping unit on the top of the writing pen, and the supporting body of the shaping unit can fully expand the elastic shaping body so that the hollow cavity inside the elastic shaping body is in the maximum expansion state. At this time, the elastic shaping body can be greatly deformed under the action of external force. When the user squeezes the elastic shaping body, the pressure can be released, so that the writing pen has the function of increasing the decompression.

[0006] Furthermore, the elastic body is closed at the top and has an opening at the bottom, the opening is sleeved outside the support body, and the flared surface of the support body extends from bottom to top and away from the center of the opening. The flared surface of the support body can not only fully expand the elastic body, but also facilitate the disassembly and assembly of the elastic body, while ensuring that the elastic body is firmly connected to the support body.

[0007] Furthermore, the support body includes a cylindrical section whose outer wall can fit with the opening, and the flared surface is an arcuate surface extending upward and radially outward from the cylindrical section.

[0008] Furthermore, the support body is a solid structure, or the support body is a hollow structure.

[0009] Furthermore, the outer wall of the upper end of the support body forms a guide surface for facilitating the insertion of the elastic molding body.

[0010] Furthermore, the top end portion of the pen body extends into the support body, and the portion is threadedly connected to the support body; a convex edge is formed on the pen body, and the support body presses the pen clip onto the convex edge.

[0011] Furthermore, the elastic body is a spherical body; or, the elastic body is an animal image; or, the elastic body is a human image; and the outer wall of the elastic body is coated with a color layer. The elastic body has various choices, high interest, and more beautiful appearance.

[0012] Furthermore, the height of the elastic body is H, the height of the support is h, and h / H is 1 / 5-1 / 2. If the above ratio is too small, the support body will not have a good effect of expanding the elastic body. If the above ratio is too large, it cannot ensure that the elastic body has a large enough hollow cavity for extrusion deformation. Under the above ratio, both sufficient expansion and a large enough deformation space can be taken into account.

[0013] Furthermore, the elastic body is made of a silicone material or a rubber material, and the hollow cavity can be deformed when subjected to force compression.

[0014] Furthermore, part of the pressing mechanism protrudes from the support body and extends into the hollow cavity; the top of the pressing mechanism has a pressing end with an increased surface area. This part of the pressing mechanism can not only support the elastic body, but also, when the pressing mechanism needs to be driven to eject the core, the user can press on the elastic body for better operation comfort; the design of the pressing end increases the force-bearing area of ​​the hand, and the operation feel is better.

[0015] The beneficial effects of the utility model are: 1) the support body not only plays the role of connecting the elastic shaped body, but also fully stretches the elastic shaped body. The elastic shaped body can be greatly deformed under the action of force and compression. The user can release the pressure by pinching the elastic shaped body, and the decompression effect is good; 2) The elastic shaped body is easy to replace, and multiple elastic shaped bodies can be used as a set. The user can disassemble and replace the elastic shaped body by himself according to the needs, which is very interesting to use; 3) The shape of the elastic shaped body is changeable, and the writing pen is highly aesthetic; 4) The user presses the elastic shaped body to drive the pressing mechanism, which is more comfortable to operate and can also ensure that the pressing mechanism is effectively driven to eject the core.

[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] like Figure 1-Figure 7As shown, a writing pen includes a pen body 2 with a pen core 1, and a pressing mechanism 3 connected to the pen core 1. The pen body 2 and the pressing mechanism 3 can be any structure in existing products, and are not specifically limited. A shaping unit 4 is arranged on the top of the pen body 2, and the shaping unit 4 includes a support body 41 and an elastic shaping body 43 connected to the support body 41. The elastic shaping body 43 is covered on the outside of the support body 41 and at least partially forms a hollow cavity 43. The support body 41 has a flared surface 411 for at least partially opening the elastic shaping body 42.

[0029] The support body 41 not only connects the elastic shaping body 43, but also fully expands the elastic shaping body 43 so that the hollow cavity 43 inside the elastic shaping body 43 is in the maximum expansion state. At this time, the elastic shaping body 43 can be greatly deformed under the action of external force. When the user squeezes the elastic shaping body 43, the pressure can be released, thereby increasing the decompression function of the writing pen.

[0030] The specific shape of the elastic body 42 is not limited, and it can also be open at the top and the bottom. Fig.10 As shown, the top of the elastic body 42 is closed, and the bottom thereof has an opening 412, so that when the elastic body 42 and the support body 41 are connected, the opening 412 is sleeved on the outside of the support body 41, which is convenient for disassembly and assembly. Therefore, the elastic body 42 can be a complete set of products, and users can disassemble and replace the elastic body 42 as needed, which is more interesting to use.

[0031] In this embodiment, the elastic body 42 is made of silicone or rubber material, so that the hollow cavity 43 is squeezed by external force, and the hollow cavity 43 can be deformed by force, and the deformation is large, which is more interesting. The elastic body 42 can be a spherical body as shown in the figure, or an animal image, or an animal head, or a human image, without specific limitation. The outer wall of the elastic body 42 is coated with a color layer, that is, the outer wall of the elastic body 42 is coated with various colors, so that the appearance of the elastic body 42 is better.

[0032] like Figure 4 , Figure 7 , Figure 8 As shown, the flared surface 411 of the support body 41 extends from bottom to top in a direction away from the center of the opening 412 . In other words, the flared surface 411 of the support body 41 is in an upward expansion state, thereby fully expanding the elastic shaping body 42 .

[0033] The support body 41 includes a cylindrical section 413, and the flared surface 411 is an arcuate surface structure extending upward and radially outward from the cylindrical section 413, and the outer wall of the cylindrical section 413 fits with the opening 412. The support body 41 is designed with the cylindrical section 413 and the flared surface 411, so that the elastic molding body 42 can be more firmly connected to the support body 41, and the elastic molding body 42 is prevented from detaching from the support body 41 at will, and the elastic molding body 42 is stretched to the maximum extent, and the molding effect is better.

[0034] The figure shows that the support body 41 is a solid structure. Of course, the support body 41 can also be a hollow structure. There is no specific limitation as long as the elastic shaping body 42 can be stretched outward.

[0035] In order to increase the volume of the hollow cavity 43, the top surface of the support body 41 is a plane. Figure 4 As shown, the height of the elastic shaping body 42 is defined as H, and the height of the supporting body 41 is defined as h, then h / H is 1 / 5-1 / 2, preferably, h / H is 1 / 4-1 / 3.

[0036] In order to facilitate the insertion of the opening 412 of the elastic body 42 into the support body 41 and to connect with it, Figure 7 , Figure 8 As shown, a guide surface 414 is formed on the outer wall of the upper end of the support body 41 to facilitate the elastic molding body 42 to be covered, and the guide surface 414 is inclined from top to bottom and from inside to outside.

[0037] In order to realize the assembly of the support body 41, the top part of the pen body 2 extends into the support body 41, and the part is threadedly connected with the support body 41. Therefore, not only can the elastic body 42 be removed for replacement, but the elastic body 42 and the support body 41 can also be removed as a whole for replacement. At the same time, the pen body 2 is formed with a convex edge 21. In other words, the outer diameter of the part of the pen body 2 extending into the support body 41 is smaller than the outer diameter of the part of the pen body 2 corresponding to the refill 1. When the support body 41 is threadedly connected with the top of the pen body 2, the pen clip 5 is pressed on the convex edge 21 to realize the assembly connection of the pen clip 5, and the overall assembly structure is simplified.

[0038] The part of the pressing mechanism 3 protrudes from the top surface of the support body 41 and extends into the hollow cavity 43. This part can not only support the elastic body 42, but also when it is necessary to drive the pressing mechanism 3 to eject the refill 1, the elastic body 42 can be used to press the refill 1, which makes the user's operation more comfortable and can also ensure that the pressing mechanism 3 is effectively driven to eject the refill. Fig. 9 As shown, the top of the pressing mechanism 3 has a pressing end 31 with an increased surface area. The user can apply external force on the upper surface of the pressing end 31, which provides a better operating feel and avoids pricking the hand when pressing.

[0039] The above specific implementation modes are used to explain the present invention rather than to limit the present invention. Any modification and change made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
