Description

Technical Field

[0001] This utility model belongs to the field of calculator technology, and in particular relates to a calculator with a writing screen function. Background Technology

[0002] A calculator is an electronic device primarily used for mathematical calculations. It can perform basic operations such as addition, subtraction, multiplication, and division using integrated circuit chips. Some advanced calculators can even perform complex scientific calculations, such as those involving trigonometric functions, logarithms, and exponents.

[0003] Calculators currently on the market have the following problems when used:

[0004] 1. Traditional calculators can only be held in the hand or placed on a table. Since the table surface is relatively smooth, the calculator is prone to sliding when pressing the keys. Also, the calculator can only be placed flat on the table, and it is difficult to adjust the angle, making it unstable to use.

[0005] 2. When using a traditional calculator, the writing pen usually needs to be removed from the calculator. If it is not put back in the slot when you need to use it again after a while, it is easy to lose it. Putting it in the slot and then taking it out is also quite troublesome, making it inconvenient to use. Utility Model Content

[0006] The purpose of this invention is to provide a calculator with a writing screen function to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A calculator with a writing screen function includes a calculator body and buttons. A sleeve is fixedly connected to the side of the calculator body. A damping rotating shaft is embedded inside the sleeve. A rotating plate is fixedly connected to the bottom of the damping rotating shaft. There are two rotating plates. A threaded rod passes through the rotating plate. A rubber block is embedded inside the rotating plate. An internal threaded seat is sleeved on the outside of the threaded rod. A connecting block is sleeved on the outside of the threaded rod. A base plate is fixedly connected to the bottom of the connecting block.

[0008] Preferably, the calculator body has a handwriting screen on its surface, a placement slot is opened inside the calculator body, a stylus is embedded in the placement slot, a metal plate is embedded on the side of the stylus, and a side plate is fixedly connected to the surface of the calculator body. There are two side plates, and a magnetic plate is embedded on the surface of the side plate.

[0009] Preferably, a turntable is fixedly connected to the surface of the internal thread seat, and the turntable is symmetrically distributed.

[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a calculator with a writing screen function.

[0028] like Figure 1-4 As shown, this utility model discloses a calculator with a writing screen function, including a calculator body 1 and buttons 7. A sleeve 10 is fixedly connected to the side of the calculator body 1. A damping shaft 4 is embedded inside the sleeve 10. A rotating plate 5 is fixedly connected to the bottom of the damping shaft 4. There are two rotating plates 5. A threaded rod 16 passes through the rotating plate 5. A rubber block 19 is embedded inside the rotating plate 5. An internal threaded seat 18 is sleeved on the outside of the threaded rod 16. A connecting block 11 is sleeved on the outside of the threaded rod 16. A base plate 6 is fixedly connected to the bottom of the connecting block 11. By installing the sleeve 10 on the side of the calculator body 1, with the damping shaft 4 embedded inside the sleeve 10, and the rotating plate 5 installed at the bottom of the damping shaft 4, the rotating plate 5 is rotated. A rubber block 19 is embedded inside the plate 5. An internal threaded seat 18 is sleeved on the outside of the threaded rod 16. A connecting block 11 is sleeved on the outside of the threaded rod 16. A base plate 6 is installed at the bottom of the connecting block 11. When the calculator needs to be placed on the table for use, it is first installed on the table through the base plate 6. At this time, the angle of the calculator can be adjusted by rotating the calculator body 1, so that the calculator drives the sleeve 10 to rotate outside the damping shaft 4. The rotating plate 5 rotates outside the threaded rod 16. When it is rotated to a suitable angle, the internal threaded seat 18 can be rotated. The internal threaded seat 18 squeezes the rubber block 19, which can fix the rotating plate 5. At this time, the calculator body 1 can be placed more stably and the angle can be adjusted more easily.

[0029] The calculator body 1 has a handwriting screen 2 on its surface and a placement slot 20 inside. A stylus 3 is embedded in the placement slot 20, and a metal plate 15 is embedded on the side of the stylus 3. Two side plates 13 are fixedly connected to the surface of the calculator body 1. A magnetic plate 14 is embedded on the surface of the side plates 13. By adding a handwriting screen 2 to the surface of the calculator body 1, and having a placement slot 20 inside the calculator body 1 with a stylus 3 embedded in the placement slot 20 and a metal plate 15 embedded on the side of the stylus 3, and by installing side plates 13 on the surface of the calculator body 1 and embedding magnetic plates 14 on the surface of the side plates 13, when the stylus 3 needs to be removed for a short time and then used again, it can be placed directly between the two side plates 13. The metal plate 15 on the surface of the stylus 3 is firmly attracted by the magnetic plate 14 on the surface of the side plate 13, which can prevent the stylus 3 from being lost and make it easier to take it out for use again. When the calculation is finished and it needs to be put away, it can be placed back into the placement slot 20, making it more convenient to use.

[0030] The internal thread seat 18 is fixedly connected to a turntable 17, which is symmetrically distributed. By mounting the turntable 17 on the surface of the internal thread seat 18, the internal thread seat 18 can be easily rotated by holding the turntable 17.

[0031] The bottom of the base plate 6 is fixedly connected to a suction cup 9. There are three suction cups 9. By installing the suction cups 9 on the bottom of the base plate 6, the base plate 6 can be easily fixed in the desired position.

[0032] The bottom of the calculator body 1 is fixedly connected to a support plate 12, and a rubber plate 8 is inlaid on the surface of the support plate 12. By installing the support plate 12 at the bottom of the calculator body 1 and inlaying the rubber plate 8 on the surface of the support plate 12, the stylus 3 can be supported.

[0033] The top of the stylus 3 is fixedly connected to a pull plate 21. The pull plate 21 is arc-shaped. By installing the pull plate 21 on the top of the stylus 3, the stylus 3 can be easily taken out from the placement slot 20 by holding the pull plate 21.

[0034] The working principle of this calculator with a writing screen function is as follows: When using this calculator on a table, first mount it on the table using the base plate 6 and suction cup 9. Then, adjust the calculator's angle by rotating the calculator body 1. This causes the calculator to rotate the sleeve 10 outside the damping shaft 4, and the rotating plate 5 outside the threaded rod 16. When the appropriate angle is reached, rotate the internal threaded seat 18. Hold the turntable 17 and squeeze the internal threaded seat 18 against the rubber block 19. This fixes the rotating plate 5, making the calculator body 1 more stable and facilitating angle adjustment. The calculator can be activated. By pinching the pull plate 21, the stylus 3 can be taken out and the operation can be started on the handwriting screen 2. Press the button 7 to perform calculations. When you need to leave briefly after taking out the stylus 3 and then continue using it, you can simply place the stylus 3 directly between the two side plates 13. The metal plate 15 on the surface of the stylus 3 is firmly attracted by the magnetic plate 14 on the surface of the side plate 13. The rubber plate 8 embedded on the surface of the support plate 12 can support the stylus 3, which can prevent the stylus 3 from being lost and make it easier to take it out again. When you need to put it away after the calculation is completed, you can put it in the placement slot 20, making it more convenient to use.
