Description

Technical Field

[0001] The utility model relates to the technical field of office supplies, in particular to a pen holder with a magnetic adsorption function. Background Art

[0002] As a tool for writing or drawing, the pen is a great invention of mankind. Most people use the pen tip to draw words, symbols or pictures on paper or other solid surfaces with colored solids or liquids. There are also pencils and charcoal pencils that use the hardness of the solid pen tip to write and draw. In my country, the pen, ink, paper and inkstone are collectively known as the Four Treasures of the Study.

[0003] However, in the prior art, pens on the market usually adopt a structure of a pen cap and a pen barrel. After use, the pen cap is fixed to one end of the pen barrel to protect the pen core. In public office places, the pen cap is often fixed on the desktop for others to use, but the fixing method is often bonded with double-sided tape or glue, which is troublesome when moving and replacing. Moreover, when people need to put the pen barrel back into the pen barrel after use, they need to press down so that the pen barrel and the pen cap will not loosen. Often after use, people forget to press down, causing the pen barrel to loosen and fall, resulting in damage to the pen barrel and affecting its use. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model adopts the following technical solution to solve the technical problems: a pen body with a magnetic adsorption function, comprising a rod body; a sleeve, the inner wall of the sleeve is slidably connected to the outer wall of the rod body; a magnetic ring, the inner wall of the magnetic ring is fixedly connected to the outer wall of the rod body; a tension spring, the bottom end of the tension spring is fixedly connected to the bottom end of the sleeve; the pen body with a magnetic adsorption function also includes: a fixing mechanism, the fixing mechanism is used to fix the sleeve, the top of the fixing mechanism is fixedly connected to the bottom end of the sleeve; a limiting mechanism, the limiting mechanism is used to fix the rod body, the outer wall of the limiting mechanism is slidably connected to the inner wall of the sleeve; the limiting mechanism includes a limiting cylinder, a limiting ring is provided at the bottom of the limiting cylinder, the outer wall of the limiting ring is symmetrically rotatably connected to a pull rod, the outer wall of the pull rod is slidably connected to a connecting rod, the end of the connecting rod close to the pull rod is rotatably connected to a rotating column, and the outer wall of the rotating column is fixedly connected to a drag spring.

When the rod body enters the sleeve, the magnetic ring on the outer wall of the rod body is magnetically attracted to the limit cylinder, causing the limit cylinder to slide upward, and when the rod body leaves, the limit cylinder slides and resets under the action of the tension spring.

[0006] Preferably, the end of the connecting rod away from the rotating column is fixedly connected to the inner wall of the limiting cylinder, the outer wall of the rotating column is slidably connected to the inner wall of the pull rod, and the end of the drag spring away from the rotating column is fixedly connected to the inner wall of the pull rod. The bottom end of the rod body enters the limiting ring, pushes the limiting ring to move downward, and drives the pull rod to move until the pull rod contacts the outer wall of the bottom end of the rod body, supporting it so that it cannot move.

[0007] Preferably, the fixing mechanism comprises a fixing plate, the top end of the fixing plate is fixedly connected to a rotating block, the bottom end of the fixing plate is fixedly connected to a suction cup, the end of the fixing plate away from the rotating block is sleeved with a clamping ring, the outer wall of the rotating block is fixedly connected to a friction plate, the inner wall of the rotating block is rotatably connected to the fixing block, the outer wall of the fixing block is fixedly connected to a rubber sheet, the inner wall of the clamping ring is threadedly connected to an adjusting rod, and the bottom end of the adjusting rod is rotatably connected to a clamping plate. The fixing plate is fixed by adsorbing the suction cup at the bottom end of the fixing mechanism to the table top, or the clamping plate can be placed under the table top, and then the adjusting rod is rotated to drive the rotatably connected clamping plate to move upward through the threaded connection with the clamping ring, and the table is clamped by the clamping plate and the fixing plate, so that the fixing structure cannot move.

[0008] Preferably, the outer wall of the friction plate is slidably connected to the outer wall of the rubber plate, the top of the fixed block is fixedly connected to the bottom of the sleeve, and the outer wall of the clamping ring is slidably connected to the inner wall of the fixed plate. The fixed block is pushed to rotate on the inner wall of the rotating block, and the friction between the rubber plate and the outer wall of the friction plate achieves a damping effect, thereby adjusting the use angle of the sleeve, and the fixed block cannot rotate in the rotating block without external force.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. The utility model is provided with a fixing mechanism, which is fixed to the desktop by adsorption through the suction cup at the bottom. The clamping plate can also be placed under the desktop. At this time, the adjusting rod is rotated to drive the rotatably connected clamping plate to move upward. The table is clamped by the clamping plate and the fixing plate, so that the fixing structure cannot move. The overall structure is simple and can be quickly fixed and disassembled.

[0011] 2. The utility model sets a limiting mechanism, and the rod body enters the sleeve. Through the magnetic adsorption of the magnetic ring and the limiting cylinder, the limiting cylinder slides upward, and the bottom end of the rod body enters the limiting ring. The limiting ring moves downward under the push of the rod body, and drives the pull rod to move until the pull rod contacts the outer wall of the bottom end of the rod body and supports it, so that the rod body cannot be loosened, thereby quickly completing the fixation of the rod body, and the operation is simple and convenient.

[0021] The end of the tension spring 6 away from the sleeve 1 is fixedly connected to the bottom end of the limit tube 501, the outer wall of the limit tube 501 is slidably connected to the inner wall of the sleeve 1, and the outer wall of the rod body 2 is slidably connected to the inner wall of the limit tube 501. When the rod body 2 enters the sleeve 1, the magnetic ring 4 fixedly connected to the outer wall of the rod body 2 and the magnetic attraction of the limit tube 501 cause the limit tube 501 to slide upward on the inner wall of the sleeve 1. When the rod body 2 moves away, the fixedly connected tension spring 6 causes it to move and reset.

[0022] One end of the connecting rod 504 away from the rotating column 506 is fixedly connected to the inner wall of the limiting cylinder 501, the outer wall of the rotating column 506 is slidably connected to the inner wall of the pull rod 503, and one end of the drag spring 505 away from the rotating column 506 is fixedly connected to the inner wall of the pull rod 503. The bottom end of the rod body 2 enters the limiting ring 502, and the limiting ring 502 moves downward under the push of the rod body 2, driving the rotationally connected pull rod 503 to move until the outer wall of the pull rod 503 contacts the outer wall of the bottom end of the rod body 2, making it unable to move.

[0023] The fixing mechanism 3 comprises a fixing plate 301, the top of the fixing plate 301 is fixedly connected with a rotating block 302, the bottom of the fixing plate 301 is fixedly connected with a suction cup 306, a clamping ring 307 is sleeved on one end of the fixing plate 301 away from the rotating block 302, a friction plate 303 is fixedly connected with the outer wall of the rotating block 302, the inner wall of the rotating block 302 is rotatably connected with a fixing block 304, a rubber sheet 305 is fixedly connected with the outer wall of the fixing block 304, an adjusting rod 308 is threadedly connected with the inner wall of the clamping ring 307, and a clamping plate 309 is rotatably connected with the bottom end of the adjusting rod 308. The suction cup 306 fixedly connected with the bottom end of the fixing mechanism 3 is adsorbed with the tabletop, so that the fixing plate 301 is fixed, and the clamping plate 309 is also placed under the tabletop. At this time, the adjusting rod 308 is rotated, and the rotatably connected clamping plate 309 is driven to move upward through the threaded connection between the adjusting rod 308 and the clamping plate 309 and the fixing plate 301.

[0024] The outer wall of the friction plate 303 is slidably connected to the outer wall of the rubber plate 305, the top of the fixed block 304 is fixedly connected to the bottom of the sleeve 1, and the outer wall of the snap ring 307 is slidably connected to the inner wall of the fixed plate 301. The friction between the outer walls of the rubber plate 305 and the friction plate 303 achieves a damping effect, thereby adjusting the use angle of the sleeve 1, and the rotating block 302 rotates on the outer wall of the fixed plate 301, thereby adjusting the rotation direction of the sleeve 1.

[0025] Working principle:

[0026] When in use, the suction cup 306 at the bottom of the fixing mechanism 3 is adsorbed on the desktop to fix the fixing plate 301, and the clamping ring 307 can also be clamped on the inner wall of the fixing plate 301 to make the clamping plate 309 under the desktop. At this time, the adjusting rod 308 is rotated, and the threaded connection between it and the clamping ring 307 drives the rotatably connected clamping plate 309 to move upward, and the clamping plate 309 and the fixing plate 301 clamp the desktop, so that the fixing mechanism 3 cannot move; the fixing block 304 rotates on the inner wall of the rotating block 302, and the friction between the rubber sheet 305 and the outer wall of the friction plate 303 achieves a damping effect, thereby adjusting the use angle of the sleeve 1, and the rotating block 302 rotates on the fixing plate 301 to adjust the rotation direction of the sleeve 1;

[0027] After the fixing mechanism 3 is completed, when the rod body 2 is used up, it is placed in the sleeve 1, and through the limiting mechanism 5, when the rod body 2 enters the sleeve 1, the magnetic ring 4 on the outer wall of the rod body 2 is at the top of the sleeve 1, and the limiting cylinder 501 is magnetically adsorbed by the magnetic ring 4 and the limiting cylinder 501, so that the limiting cylinder 501 slides upward. During the process of the limiting cylinder 501 sliding upward, the bottom end of the rod body 2 enters the limiting ring 502. With the continuous movement of the limiting cylinder 501, the limiting ring 502 moves downward under the push of the rod body 2, and drives the pull rod 503 to move, so that the rotating column 506 on the connecting rod 504 slides on the inner wall of the pull rod 503 until the pull rod 503 contacts the outer wall of the bottom end of the rod body 2, making it unable to move, thereby completing the fixation of the rod body 2.
