[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1 An automatic alarm pencil case includes a pencil case body 1, a pencil case top 2 is hinged on the pencil case body 1, and the four corners of the pencil case body 1 and the pencil case top 2 are rounded to prevent the user from being injured when taking the pencil case;

[0029] Reference Figure 1-3A plurality of trigger blocks 10 are slidably connected to the stationery placement positions in the top 2 of the pencil case, and a mounting cavity is provided in the top 2 of the pencil case. A threaded rod 4 is rotatably connected in the mounting cavity. A driving mechanism for driving the threaded rod 4 to rotate is provided in the mounting cavity. The driving mechanism includes a rack 5 slidably connected to the side wall of the mounting cavity, and a gear 7 cooperating with the rack 5 is fixedly connected to the threaded rod 4. A horizontally arranged first spring 6 is fixedly connected to the end of the rack 5 away from the gear 7. The end of the first spring 6 away from the rack 5 is fixedly connected to the side wall of the mounting cavity. When the rack 5 is acted upon by the first spring 6, it will move horizontally, thereby cooperating with the gear 7 to drive the threaded rod 4 to rotate. A connecting block 8 is sleeved on the rod 4 and connected by a thread, and the bottom of the connecting block 8 is slidably connected to the bottom of the installation cavity. The bottom of the connecting block 8 is slidably connected to the bottom of the installation cavity so that the installation cavity serves to limit the connecting block 8. A touch block 9 is fixedly connected to the upper end of the connecting block 8. A trigger alarm 3 is fixedly connected to the installation cavity, and the trigger alarm 3 is located at the upper end of the threaded rod 4 away from the touch block 9. When the threaded rod 4 rotates, the connecting block 8 is limited by the installation cavity and guided by the threaded rod 4 to the connecting block 8, so that the connecting block 8 moves toward the trigger alarm 3. When the touch block 9 touches the trigger alarm 3, the trigger alarm 3 can issue a warning.

[0030] The mounting cavity is provided with a plurality of triggering blocks 10 corresponding to the plurality of triggering mechanisms which make the touch block 9 move toward the trigger type alarm 3. The triggering mechanism realizes the function of detecting whether there are stationery in the stationery place in the pencil case. The triggering mechanism comprises a secondary wedge 11 which is slidably connected to the mounting cavity. Both ends of the secondary wedge 11 are fixed with connecting plates 18. The secondary wedge 11 is fixedly connected with a U-shaped block 22 which is adapted to the threaded rod 4 through the connecting plates 18 at both ends. The inner wall of the U-shaped block 22 abuts against the threaded rod 4. The top of the touch block 9 is fixedly connected with a main wedge 12. The main wedge 12 abuts against the inclined surface of the secondary wedge 11. The U-shaped block 22 is opened on the threaded rod 4 to realize the function of preventing the connection block 8 from moving toward the trigger type alarm 3. When there are stationery in the pencil case, the stationery squeezes the triggering block 10 to drive the main wedge 12 to move upward. The inclined surface of the main wedge 12 squeezes the inclined surface of the secondary wedge 11, so that the secondary wedge 11 drives the U-shaped block 22 to move away from the threaded rod 4, thereby making The U-shaped block 22 no longer hinders the movement of the connecting block 8. At the same time, a baffle 21 is fixedly connected to the side of the auxiliary wedge 11 away from the U-shaped block 22 on the installation cavity. The baffle 21 and the auxiliary wedge 11 are fixedly connected by the second spring 13. The auxiliary wedge 11 can be reset by the second spring 13 to facilitate the next detection. When there is no stationery in the pencil case, the trigger block 10 is not squeezed, so that the main wedge 12 cannot be driven to rise, so that the U-shaped block 22 cannot be moved away from the threaded rod 4, so that the U-shaped block 22 hinders the movement of the connecting block 8. When there are several stationery placements in the pencil cases without stationery, several U-shaped blocks 22 will be left at the threaded rod 4, even if the connecting block 8 cannot pass through the U-shaped block 22 so that the touch block 9 touches the trigger alarm 3 to sound an alarm. Therefore, when the trigger alarm 3 does not sound an alarm, it can be known that the stationery is missing in the pencil case, reminding the user that the stationery is not put away, thereby preventing the loss of stationery.

[0031] Reference Figure 4-5The pencil case body 1 is provided with a pin cavity 16 on the side, and a slide groove 14 corresponding to the pin cavity 16 is provided in the installation cavity. An L-shaped pin block 15 is fixedly connected to the side of the rack 5, and the L-shaped pin block 15 passes through the slide groove 14 and is slidably connected to the slide groove 14. The top 2 of the pencil case is provided with a slide cavity 17 corresponding to the slide groove 14, and a push block 20 passing through the slide cavity 17 is fixedly connected to the top of the rack 5, and the slide cavity 17 is slidably connected to the push block 20. When the rack 5 moves to the maximum distance, the L-shaped pin block 15 is just stuck in the pin cavity 16 to prevent the pencil case from opening. At the same time, if the connecting block 8 is blocked by the U-shaped block 22, causing the rack 5 to be unable to rotate, it will cause the L-shaped pin block 1 5 cannot be stuck in the pin cavity 16, which is also a way to remind that stationery is missing. At the same time, the top of the rack 5 is also fixedly connected with a push block 20 that penetrates the sliding cavity 17. When the pencil case is opened, the pin block is no longer stuck in the pin cavity 16 by pulling back the push block 20. At this time, the rack 5 will be pulled, so that the threaded rod 4 is reversed, so that the connecting block 8 is reset away from the trigger alarm 3. After opening the pencil case, the touch block 9 is no longer squeezed, and the second spring 13 will also reset the U-shaped block 22, so that the U-shaped block 22 again hinders the movement of the connecting block 8 toward the trigger alarm 3, thereby resetting the overall state of the device, and when the pencil case is closed again, detection can be performed again.

[0032] Working principle: When closing the pencil case, the trigger block 10 will decide whether to be lifted up according to whether there are stationery in the stationery placement position. When there are stationery in the stationery placement position, the main wedge block 12 squeezes the auxiliary wedge block 11 to drive the U-shaped block 22 away from the threaded rod 4, so that the connecting block 8 can move toward the trigger alarm 3 without hindrance, so that the touch block 9 can touch the trigger alarm 3 to remind the user that all the stationery is there. When there are several stationery placements in the pencil cases without stationery, then several U-shaped blocks 22 will be left at the threaded rod 4, that is, the connecting block 8 cannot pass through the U-shaped block 22 so that the touch block 9 touches the trigger alarm 3 to sound an alarm. Therefore, when the trigger alarm 3 does not sound an alarm, it can be known that there is a lack of stationery in the pencil case, and it also reminds the user that the stationery has not been put away, thereby preventing the loss of stationery.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
