Description

Technical Field

[0001] This utility model relates to the field of stationery technology, and in particular to a novel pen ruler. Background Technology

[0002] Pens are used for writing, and rulers are used for measuring and drawing. In the drawing process, the two tools often need to work together. Pens and rulers are essential stationery for students. Currently, most pens and rulers are two separate units, which are inconvenient to carry. Although there are a few pens and rulers that can be combined, they are inconvenient to disassemble, which affects the efficiency of use. Therefore, a new type of pen and ruler is proposed to solve the problems mentioned above. Utility Model Content

[0003] This invention addresses the problem that current pen rulers are mostly separate units, inconvenient to carry, and prone to ink adhesion in the ruler sleeve. It provides a new type of pen ruler that can be assembled, is easy to carry, and can be quickly disassembled, effectively solving the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows:

[0005] A novel pen ruler includes a ruler sleeve and a pen body. The ruler sleeve has a fan-shaped cross-section, with the thinner end of the ruler sleeve inclined at an angle of 5 to 60 degrees. Scale lines are provided on the inclined end faces of the ruler sleeve, and a slot for placing the pen body is provided on the thicker end of the ruler sleeve. The pen body includes a pen barrel and a pen tip. A fixing device for locking the pen barrel is provided on the inner wall of the slot, and a keyway is also provided on the slot.

[0006] The fixing device is a magnet, which is embedded in the inner wall of the slot, and the pen barrel is a metal tube.

[0007] The fixing device is a cylindrical tube, which is fixed to the inner wall of the slot. The inner wall of the cylindrical tube is provided with a movable locking pin, which has a rounded corner. The pen barrel has a locking groove that cooperates with the locking pin.

[0008] A circular ring pad that slides through the cylindrical tube is fixed to the outer surface of the pin, and a spring that cooperates with the circular ring pad is fixed to the inner wall of the bottom end of the cylindrical tube. A pull ring is also fixed to the outer surface of the pin.

[0009] The inner wall at the bottom of the slot is provided with a plug, and the plug is provided with a sealing gasket that matches the pen tip.

[0010] The outer surface of the pen barrel is provided with a rubber sleeve corresponding to the keyway.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] When in use, the chamfer prevents ink from contacting the ruler sleeve when drawing lines, ensuring its cleanliness. The slot is for holding the pen body and is equipped with a fixing device to lock the pen body and prevent it from falling out. The keyway and rubber sleeve allow the rubber sleeve to be exposed when the pen body is placed in the slot. By moving the rubber sleeve by hand, the pen body can be moved out of the slot for easy removal. Attached Figure Description

[0019] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1-5 As shown, this utility model provides a novel pen ruler, including a ruler sleeve 1 and a pen body. The ruler sleeve 1 has a fan-shaped cross-section, with the thinner end of the ruler sleeve inclined at an angle of 5-60 degrees. Scale lines 16 are provided on the inclined end faces of the ruler sleeve 1, and a slot 15 for placing the pen body is provided on the thicker end of the ruler sleeve 1. The pen body includes a pen barrel 2 and a pen tip 14. A fixing device for locking the pen barrel 2 is provided on the inner wall of the slot 15, and a keyway 4 is also provided on the slot 15.

[0021] like Figure 1-3 As shown, the ruler sleeve 1 has a thin end and a thick end, as... Figure 1 or Figure 3As shown, the thin end of the ruler sleeve has an inclination angle of 5-60 degrees, which conforms to the ergonomic principle, with an optimal included angle of 25 degrees; the scale line 16 can help the user draw line segments of a specified length; the slot 15 is used to place the pen body, and a fixing device is also provided in the slot 15, which can lock the pen barrel 2 to prevent the pen body from falling.

[0022] The fixing device is a magnet 5, which is embedded in the inner wall of the slot 15, and the pen barrel 2 is a metal tube.

[0023] like Figure 2 As shown, magnet 5 can attract and fix the metal tube, so that the pen body is fixed in a fixed state after being placed on the inner wall of slot 15, preventing it from falling.

[0024] The fixing device is a cylindrical tube 8, which is fixed to the inner wall of the slot 15. The inner wall of the cylindrical tube 8 is provided with a movable locking pin 9, and the locking pin 9 is provided with a rounded corner 10. The pen barrel 2 is provided with a locking groove that cooperates with the locking pin 9.

[0025] like Figure 4-5 As shown, the cylindrical groove is used to limit the movement of the locking pin 9 to only move back and forth. By inserting the pen body into the inner wall of the groove 15, the groove can meet the locking pin 9. After the groove and the locking pin 9 meet, the locking pin 9 can move backward to engage with the groove, thereby restricting the movement of the pen body. The rounded corner 10 can reduce the friction when the locking pin 9 contacts the pen body.

[0026] A circular ring pad 11 that slides with the cylindrical tube 8 is fixedly connected to the outer surface of the locking pin 9. A spring 12 that cooperates with the circular ring pad 11 is fixedly connected to the inner wall of the bottom end of the cylindrical tube 8. A pull ring 13 is also fixedly connected to the outer surface of the locking pin 9.

[0027] like Figure 5 As shown, the annular pad 11 can slide back and forth on the inner wall of the cylindrical tube 8. The spring 12 has a backward driving force on the annular pad 11. Even if the annular pad 11 and the locking pin 9 have a backward driving force and are in the rearmost position under normal conditions, the pull ring 13 facilitates the forward movement of the locking pin 9. When the pen body is inserted into the inner wall of the slot 15, the tapered design of the pen tip 14 allows the locking pin 9 to move forward and enter the inner wall of the cylindrical tube 8 after contact with it. When the pen body moves to the point where the slot meets the locking pin 9, the locking pin 9 will move backward and reset under the elastic force of the spring 12, that is, the slot and the locking pin 9 are engaged, which can limit the movement of the pen body. When it is necessary to remove the pen body, by pulling the pull ring 13 forward, the locking pin 9 can move forward and disengage from the slot, and the pen body can be removed. With the cooperation of the locking pin 9 and the slot, the pen body can be more stably fixed in the slot 15. The cost is relatively high, and the setting is selected according to the requirements.

[0028] The inner wall at the bottom of the slot 15 is provided with a cap 6, and the cap 6 is provided with a sealing gasket 7 that matches the pen tip 14.

[0029] like Figure 4 As shown, the cap 6 is fixed to the inner wall of the slot 15. The cap 6 is used to support the sealing gasket 7. The sealing gasket 7 can seal the pen tip 14 to prevent ink leakage.

[0030] The outer surface of the pen barrel 2 is provided with a rubber sleeve 3 corresponding to the keyway 4.

[0031] like Figure 1 As shown, with the keyway 4 and rubber sleeve 3, when the pen body is placed in the slot 15, the rubber sleeve 3 can be exposed in the keyway 4. By moving the rubber sleeve 3 by hand, the pen body can be moved out of the slot 15, making it easy to take out the pen body.

[0032] In use, the slot 15 is used to place the pen body. A fixing device is also provided in the slot 15 to lock the pen barrel 2, thereby preventing the pen body from falling out. With the key groove 4 and rubber sleeve 3, when the pen body is placed in the slot 15, the rubber sleeve 3 can be exposed in the key groove 4. By moving the rubber sleeve 3 by hand, the pen body can be moved out of the slot 15, making it easy to take out the pen body.
