Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of writing pen, in particular to a simple pen clip structure preventing falling off. BACKGROUND

[0002] At present, the pen for writing can be divided into two categories: cap pen and click pen. The pen clip of cap pen is generally arranged on the pen cap, and the pen clip of click pen is arranged on the pen barrel. The click pen is widely used because it does not need to be pulled off, is convenient to use and easy to carry.

[0003] The pen clip structure on the traditional click pen is generally divided into two types. One is that the pen clip is integrally formed on the pen barrel, and the pen clip is held on the book or the like by the elastic force of itself. Although this technical scheme has simple structure and can be integrally processed by injection molding process, it needs to be operated by two hands when used, one hand holds the pen and the other hand pries open the pen clip to hold it, which causes inconvenience in use. The other is that the pen clip is hinged on the pen barrel, and a spring is arranged between the pressing part of the pen clip and the pen barrel. The pen clip is clamped on the pen barrel by the elastic force of the spring. Although this technical scheme can be operated by one hand, the pen clip structure uses more components, is complicated to assemble and has high production cost. Therefore, it is necessary to improve the prior art to overcome the defects in the prior art. SUMMARY

[0004] In order to solve the above technical problems, the present application provides a simple pen clip structure preventing falling off, which not only has simple structure, is easy to assemble, reduces production cost, can be operated by one hand, is very convenient to use, but also is not easy to disassemble and avoids falling off and loss.

[0005] The technical scheme adopted by the present application to solve the technical problems is as follows: a simple pen clip structure preventing falling off, comprising:

[0006] A pen barrel is provided with an installation part along the outer peripheral surface;

[0007] A pen clip is a frame member formed by bending a wire and having elastic deformation capacity. An upper end part of the frame member is formed with a pressing part, and a lower end part is formed with a clamping part. Both ends of the wire are bent to extend into the frame member and are formed with two pivot parts between the pressing part and the clamping part. One end of each of the two pivot parts is at least partially bent to form a bent part.

[0008] A gland is fixed on the installation part and is formed with two installation holes and a groove therebetween. The two pivot parts are rotatably arranged in the two installation holes, and the bent part is limited in the groove.

[0009] The pen clip and the pen barrel can make the clamping portion abut against the outer circumferential surface of the pen barrel and drive the frame member to elastically deform in the assembled state, so as to apply an elastic force to the clamping portion towards the pen barrel.

[0010] As a further improvement of the present application, the groove is formed by recessing the side of the mounting portion close to the gland in the longitudinal direction, the outer side of the bending portion is stopped on the inner wall of the groove in the longitudinal direction, and the bending portion can rotate in the groove following the rotation of the shaft portion.

[0011] As a further improvement of the present application, the gland is provided with a boss in the longitudinal direction towards the side of the mounting portion, and the boss is inserted into the groove.

[0012] As a further improvement of the present application, the upper and lower ends of the gland are clamped on the mounting portion by buckling.

[0013] As a further improvement of the present application, the upper and lower ends of the gland are extended to form clamping portions towards the pen barrel, the opposite inner sides of the two clamping portions are provided with hook portions close to the ends in the transverse direction, and the upper and lower ends of the mounting portion are provided with clamping table portions which are clamped with the hook portions.

[0014] As a further improvement of the present application, the clamping portion is twisted away from the pen barrel relative to the pressing portion, so that the clamping portion and the pressing portion are in different planes.

[0015] As a further improvement of the present application, the two shaft portions are provided in the two mounting holes by the same side of the mounting portion, the opposite side of the frame member to the two shaft portions is provided with a connecting portion connected between the pressing portion and the clamping portion, and the connecting portion is orthographically projected on the other side of the mounting portion.

[0035] A preferred embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0036] Reference Figures 1 to 6 The present application provides a simple pen clip structure that prevents falling, comprising a pen shaft 1, a pen clip 2 and a cap 3 mounted on the pen shaft 1, the pen clip 2 being used to hold external books and other objects in cooperation with the pen shaft 1.

[0037] The pen clip 2 is a frame member which is bent from a length of wire and has elastic deformation capability, and which extends along the length direction of the pen barrel 1. The wire used for the pen clip 2 can be made of manganese steel, stainless steel or the like, so that the pen clip 2 has strong elastic deformation capability.

[0038] Referring to Figure 4 , the upper end of the frame member is bent to form a pressing portion 201, and the lower end is bent to form a clamping portion 202. The pressing portion 201 is in the shape of a U with the opening downward, and the clamping portion 202 is in the shape of a U with the opening upward. One side of the frame member has a connecting portion 205, and one end of the pressing portion 201 and one end of the clamping portion 202 are integrally connected through the connecting portion 205. In addition, the pressing portion 201 and the clamping portion 202 can also be provided in other shapes other than the U shape, such as the M shape or the shape of the end bent into a wave shape, so as to increase the pressing and clamping contact surface. The two ends of the wire are bent inwardly from the other side of the frame member to form two pivot portions 203, and the two pivot portions 203 are between the pressing portion 201 and the clamping portion 202. One end of each of the two pivot portions 203 is bent by 90° toward the direction of the pen barrel 1 to form a bent portion 204.

[0039] Referring to Figures 2 to 4 , the pen barrel 1 is provided with a mounting portion 101 along the outer circumferential surface, and the gland 3 is fixed on the mounting portion 101 and forms two mounting holes 102 and a groove 103 therebetween. Specifically, the mounting hole 102 is formed by the semicircular grooves on the mounting portion 101 and the gland 3, and the diameter of the mounting hole 102 is slightly larger than the diameter of the pivot portion 203. The two mounting holes 102 are distributed in parallel along the horizontal direction, and the centers thereof are on the same vertical plane. The groove 103 is distributed along the length direction of the pen barrel 1, i.e. the longitudinal direction, and is connected with the two mounting holes 102. The two pivot portions 203 are rotatably arranged in the two mounting holes 102 from the same side of the mounting portion 101, and the two bent portions 204 are limited in the groove 103. The connecting portion 205 opposite to the two pivot portions 203 of the frame member is orthogonally projected on the other side of the mounting portion 101, so that the pen clip 2 is rotatably arranged on the pen barrel 1 through the two pivot portions 203.

[0040] In this embodiment, the frame structure is arranged obliquely, specifically, one end of the clamping portion 202 is inclined toward the direction of the pen barrel 1, and one end of the pressing portion 201 is inclined away from the direction of the pen barrel 1. The clamping portion 202 is twisted relative to the pressing portion 201 toward the direction away from the pen barrel 1, so that the plane where the clamping portion 202 is located and the plane where the pressing portion 201 is located are two different planes, and the two planes are on a straight line where the connecting portion 205 is located. The two rotating shaft portions 203 are respectively arranged on the other end of the pressing portion 201 and the other end of the clamping portion 202 and are also on the same vertical plane.

[0041] In the assembled state of the pen clip 2 and the pen barrel 1, the clamping portion 202 can abut against the outer circumference of the pen barrel 1, and the frame member is elastically deformed, thereby exerting an elastic force on the clamping portion 202 toward the pen barrel 1, so that a certain clamping force exists between them. During operation, by exerting pressure on the pressing portion 201 of the pen clip 2, the pen clip 2 is rotated around the two rotating shaft portions 203, the pressing portion 201 is rotated toward the direction of the pen barrel 1, and the clamping portion 202 is rotated away from the direction of the pen barrel 1, so that the pen clip 2 is in an open state. After being released, the pen clip 2 restores the clamping state under the action of its own elastic force, and can be clamped on external books and other articles.

[0042] The pen clip 2 is kept on the pen barrel 1 by relying on its own elastic force to elastically abut the clamping portion 202 against the outer circumferential surface of the pen barrel 1, so that a certain clamping force exists between them, and the pen clip 2 can be lifted by one hand, which greatly facilitates use.

[0043] Referring to Figure 2 and Figure 3 , the groove 103 is formed by recessing the side of the mounting portion 101 close to the gland 3 in the longitudinal direction, and the two bending portions 204 are located in the groove 103 close to the upper and lower ends, and the bending portions 204 can rotate along the vertical plane in the groove 103. The inner wall distributed in the longitudinal direction on the groove 103 is used to stop and position the bending portion 204. When the rotating shaft portion 203 of the pen clip 2 is pulled outwardly at the mounting hole 102 by external force, the bending portion 204 will be hooked on the inner wall of the groove 103, thereby making the rotating shaft portion 203 unable to be separated from the mounting hole 102, and the pen clip 2 cannot be disassembled from the side of the mounting portion 101, preventing the pen clip 2 from being lost after being disassembled.

[0044] Referring to Figure 2 , Figure 3 and Figure 6The upper and lower ends of the grommet 3 are buckled on the mounting portion 101. Specifically, the upper and lower ends of the grommet 3 are extended to form buckling portions 302, and the opposite inner sides of the two buckling portions 302 are provided with hook portions 303 near the ends in the transverse direction. The upper and lower ends of the mounting portion 101 are provided with clamping portions 104 for cooperating with the hook portions 303. The grommet 3 is an injection molded part and has a certain elastic deformation capacity. When the grommet 3 is assembled on the mounting portion 101 and a pressure is applied, the two buckling portions 302 are extruded and expanded outward, and the grommet 3 is pushed to slide towards the pen barrel 1. Finally, the two hook portions 303 are buckled on the two clamping portions 104, respectively, and the two buckling portions 302 are tightly clamped on the upper and lower end faces of the mounting portion 101, so as to buckle the grommet 3 on the mounting portion 101.

[0045] In addition, the grommet 3 is provided with a boss 301 on the side facing the mounting portion 101 in the longitudinal direction. The width of the boss 301 matches the groove width of the groove 103. When the grommet 3 is assembled, the boss 301 is inserted into the groove 103 and located between the two bending portions 204, so as to limit the left and right sliding of the grommet 3 on the mounting portion 101.

[0046] The technical scheme of the present application has the advantages of simple structure, easy assembly, cost saving, reliable connection of components, and the grommet 3 cannot be easily disassembled, thereby avoiding disassembly of the pen clip 2 and increasing the stability of the product.

[0047] In the above description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the above description is only a preferred embodiment of the present application, and the present application can be implemented in many other ways different from those described herein. Therefore, the present application is not limited by the specific implementations disclosed above. Meanwhile, any person skilled in the art can make many possible changes and modifications to the technical scheme of the present application, or modify it into equivalent embodiments, without departing from the scope of the technical scheme of the present application. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application, without departing from the technical scheme of the present application, are still within the scope of protection of the present application.
