Technical Field
[0001] The utility model relates to the technical field of paper clips, in particular to a multifunctional paper clip. Background Art
[0002] Paper clips used on plate-shaped bodies are common office supplies. The Chinese utility model patent with the authorization announcement number CN211222692 U discloses a multifunctional paper clip with both paper clipping and paper hanging functions. Its structure is as follows Figure 1 As shown, it includes a main body 1a, and the main body 1a is provided with a mounting portion, a paper clamping portion and a paper hanging portion. The mounting portion includes a U-shaped groove 2a for connecting to the plate-like body, and a locking knob 3a arranged on one side of the U-shaped groove 2a. The paper clamping portion and the paper hanging portion are both arranged on the side of the U-shaped groove 2a away from the locking knob 3a. The paper clamping portion includes a paper clamping spring 4a, and the paper hanging portion includes a hook 5a. One end of the paper clamping spring 4a is fixedly connected to the outer side wall of the U-shaped groove 2a on the side away from the locking knob 3a, and the other end of the paper clamping spring 4a is a free end 6a. The free end 6a of the paper clamping spring 4a spans the corresponding side of the U-shaped groove 2a and elastically rests on the plate-like body 7a. The hook 5a is arranged on the outer side wall of the U-shaped groove 2a on the side away from the locking knob 3a and is located on the inner side of the paper clamping spring 4a. Figure 2 The schematic diagram shows the structure of the multifunctional paper clip installed on the plate-like body 7a. The working principle of the multifunctional paper clip is as follows: during installation, the U-shaped groove 2a is clamped on the plate-like body 7a, and the locking knob 3a on one side of the U-shaped groove 2a is tightened to fix the main body 1a on the plate-like body 7a. When clamping paper, the free end 6a of the paper clamping spring 4a is pulled apart to clamp the paper 8a in the gap between the opened paper clamping spring 4a and the plate-like body 7a. The paper clamping spring 4a is released to use its elasticity to fix the clamped paper 8a. When hanging paper, the free end 6a of the paper clamping spring 4a is pulled apart and the paper 8a is inserted through the gap between the opened paper clamping spring 4a and the plate-like body 7a. The paper 8a is hung on the hook 5a using the hanging hole on the paper 8a. The paper clamping spring 4a is released, and the free end 6a of the paper clamping spring 4a presses the hung paper 8a.
[0003] However, the existing multifunctional paper clip has the following technical problems: when hanging paper, it is necessary to push aside the free end 6a of the paper clip 4a, and then insert it onto the hook 5a through the gap between the paper clip 4a and the plate-like body 7a; because the free end 6a of the paper clip 4a is tightly pressed on the plate-like body 7a and the paper clip 4a is always blocked in front of the hook 4a, it is very difficult for the paper 8a to pass through the gap between the paper clip 4a and the plate-like body 7a, making it very inconvenient to hang paper; in addition, when hanging paper 8a, the free end 6a of the paper clip 4a will press the paper 8a, so the thicker the paper 8a, the greater the deformation of the paper clip 4a will be, and excessive deformation will easily cause damage to the paper clip 4a, thereby limiting the thickness of the suspended paper 8a. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a multifunctional paper clip which is more convenient for hanging paper and has smaller limitation on the thickness of hanging paper.
[0005] The technical solution of the present utility model is: a multifunctional paper clip, comprising a main body, wherein the main body is provided with a mounting portion, a paper clamping portion and a paper hanging portion, the paper clamping portion is arranged on the outside of the paper hanging portion, the paper clamping portion comprises a connecting arm and a paper clamping spring, one end of the connecting arm is fixedly connected to the main body, and the other end extends to the outside of the paper hanging portion and is movably connected to one end of the paper clamping spring, the other end of the paper clamping spring is a free end and can be rotated to a first position and a second position, when the free end of the paper clamping spring rotates to the first position, the paper clamping spring is unfolded relative to the connecting arm and the free end of the paper clamping spring elastically presses against the plate-like body, when the free end of the paper clamping spring rotates to the second position, the paper clamping spring is folded on the outside or inside of the connecting arm and the free end of the paper clamping spring is separated from the plate-like body, and there is a gap between the paper hanging portion and the connecting arm.
[0006] The working principle of the utility model multifunctional paper clip is as follows:
[0007] The main body is installed on the plate-like body through the installation part. When clamping paper, the paper clamping spring is rotated so that its free end is located in the first position, so that the paper can be clamped in the gap between the free end of the paper clamping spring and the plate-like body; when hanging paper, the paper clamping spring is rotated so that its free end is located in the second position. At this time, the paper clamping spring is folded on the outside or inside of the connecting arm and its free end is separated from the plate-like body. The paper clamping spring no longer blocks the paper hanging part, and the paper can be very conveniently hung on the paper hanging part through the gap between the paper hanging part and the connecting arm.
[0008] After adopting the above structure, the utility model has the following advantages:
[0009] The multifunctional paper clip of the utility model changes the traditional paper clamping structure, and splits the one-stage fixed structure into a two-stage variable structure, that is, one stage is a fixed stage and the other stage is a movable stage. The paper clamping spring piece as the movable stage can be unfolded or folded. When the paper clamping spring piece is unfolded, its free end presses against the plate-shaped body to have the paper clamping function. When the paper clamping spring piece is folded, it is stored on the outer side or inner side of the connecting arm, no longer pressing the plate-shaped body and no longer blocking the paper hanging part, so that paper can be quickly hung on the paper hanging part, making paper hanging more convenient; secondly, when hanging paper, the paper clamping spring piece is folded on the outer side or inner side of the connecting arm, no longer pressing the paper, so the paper clamping spring piece does not limit the thickness of the suspended paper, as long as the gap between the paper hanging part and the connecting arm is reasonably set, the corresponding paper hanging thickness requirement can be met, and the gap between the paper hanging part and the connecting arm can be flexibly set according to needs, so the restriction on the paper hanging thickness is small; in addition, in the case where the plate-shaped body does not have magnetism or a special paper hanging area, the functions of paper clamping and paper hanging can be achieved by installing this structure, which is very convenient to use.
[0010] Preferably, the mounting portion includes a U-shaped groove for connecting with the plate-like body and a locking knob arranged on one side of the U-shaped groove. The mounting portion has a simple structure, is easy to install, and is adaptable to plate-like bodies of different thicknesses.
[0011] As an advantage, the paper clamping spring and the paper hanging portion are both arranged on the side of the U-shaped groove away from the locking knob. This arrangement is reasonable and convenient for both disassembling and assembling the main body and for clamping and hanging paper.
[0012] Preferably, the paper hanging portion is arranged on the outer side wall of the U-shaped groove away from the locking knob. This arrangement facilitates the arrangement of the paper hanging portion, simplifies its structure, and makes hanging convenient.
[0013] Preferably, the inner sidewall of the U-shaped groove, away from the locking knob, is provided with a flange that can press against the plate-like body. This arrangement utilizes the elastic gap formed by the flange and the plate-like body as a secondary paper clamp, providing greater flexibility and functionality. Furthermore, positioning the flange and hook on the inner and outer sidewalls of the U-shaped groove, away from the locking knob, respectively, results in a simpler and more compact structure, while preventing interference between paper clamping and paper hanging.
[0014] Preferably, the U-shaped groove is closed at the top and open at the bottom, and includes a hanging plate and a locking plate provided on both sides, the locking knob is provided on the locking plate, and the paper hanging portion is provided on the outer side wall of the hanging plate. This arrangement makes it more convenient to hang paper.
[0015] Preferably, one end of the connecting arm is fixedly connected to the outer wall of the U-shaped groove, and the other end extends downward along the outer side of the U-shaped groove away from the locking knob to the outside of the paper hanging part. This arrangement allows the paper hanging part to be hidden behind the connecting arm, making the structure more simple and compact.
[0016] Preferably, one end of the connecting arm is fixedly connected to the hanging plate or the locking plate, and the other end of the connecting arm extends to the outside of the paper hanging portion. This arrangement can make the overall layout more reasonable and the structure more simple and beautiful after the connecting arm is connected to the U-shaped groove.
[0017] Preferably, the paper clamping spring is movably connected to the outer side of the connecting arm via a pivot, and a positioning structure is provided between the two abutting surfaces of the paper clamping spring and the connecting arm, for positioning the free end of the paper clamping spring to a first position and a second position. This arrangement ensures a reliable connection between the paper clamping spring and the connecting arm and enables reliable positioning of the paper clamping spring.
[0018] Preferably, a cavity for accommodating a positioning structure is provided between the two mating surfaces of the paper clamping spring and the connecting arm. The positioning structure includes an annular protrusion, two positioning grooves provided on the annular protrusion, and two positioning protrusions that cooperate with the positioning grooves. The annular protrusion and the positioning protrusions are respectively provided on the two mating surfaces of the paper clamping spring and the connecting arm. When the paper clamping spring rotates relative to the connecting arm, the two positioning protrusions can slide on the annular protrusion and be positioned in the two positioning grooves. This arrangement can conceal the positioning structure between the two mating surfaces of the paper clamping spring and the connecting arm, and the positioning structure is simple and reliable.
[0019] Preferably, two elastic sheets are cut from the two mating surfaces of the paper clamping spring and the connecting arm, the mating surface on which the positioning protrusion is provided. One end of the elastic sheet is connected to the corresponding mating surface, and the other end is a free end. The two positioning protrusions are respectively provided on the free ends of the two elastic sheets. Providing the positioning protrusions on the elastic sheet can facilitate positioning and separation of the positioning protrusions from the positioning groove by utilizing the deformation of the elastic sheet.
[0020] Preferably, the two elastic sheets are arc-shaped and match the trajectory of the annular protrusion. This arrangement can make the deformation direction of the elastic sheet match the movement direction of the positioning protrusion, thereby making it easier to achieve the positioning and separation of the positioning protrusion and the positioning groove.
[0021] Preferably, the pivot is provided on one of the paper clamping spring and the connecting arm, and a bearing seat is provided on the other. The pivot is a screw, and the bearing seat is a threaded column. The threaded column is provided in the cavity and is located at the center of the annular protrusion.
