Description

Technical Field

[0001] This invention belongs to the field of teaching aids technology, specifically relating to a portable multimedia teaching aid. Background Technology

[0002] With the development of technology, modern teaching methods differ greatly from traditional ones. More and more multimedia teaching aids are entering schools to help teachers better conduct their teaching work. In particular, OCR cameras are widely used on campuses. Portable cameras are especially popular among teachers due to their portability. These cameras consist of two parts: a support rod and a folding rod. The support rod is connected to the folding rod via a damping mechanism. The camera is mounted on the folding rod, and the support rod connects to the desktop for support. When needed, the folding rod is rotated to create a 90-degree angle with the support rod, and the materials are placed under the folding rod. The camera captures the image and uploads it to the display screen, thus aiding teaching. However, because portable cameras are carried around, they are easily dropped due to accidents. Since the folding rod and support rod are simply connected by rotation, they can easily unfold upon impact, exposing the camera and causing damage. Summary of the Invention

[0003] The purpose of this invention is to provide a portable multimedia teaching aid to address the problems existing in the prior art.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0005] A portable multimedia teaching aid includes a camera and a mounting rod. The mounting rod has an upward-opening mounting groove inside. The upper side of the mounting rod has a notch communicating with the mounting groove. A sealing block is slidably and sealingly fitted inside the mounting groove. A limit mechanism is fitted between the sealing block and the mounting rod. A shooting rod is rotatably fitted on the upper side of the sealing block via a damping shaft. The camera is located on the side of the shooting rod away from the sealing block. An air outlet pipe communicating with the mounting groove is provided on the lower side of the mounting rod. A distribution pipe is connected to the upper end of the air outlet pipe. The distribution pipe is fitted on the lower side of the notch. The distribution pipe is fitted with several nozzles, and the ends of the nozzles away from the distribution pipe are all deflected towards the notch.

[0006] The limiting mechanism includes a stepped hole on the side of the sealing block, a spring-loaded component in the stepped hole, a T-shaped locking member extending out of the stepped hole, and locking holes communicating with the mounting groove on both the upper and lower sides of the mounting rod side wall. Both locking holes are matched with the T-shaped locking member. The outer wall of the mounting rod is provided with two sealing abutment components that are matched with the two locking holes respectively.

[0007] The rebound assembly includes a spring disposed inside the stepped hole, and the other end of the spring is connected to a T-shaped locking member.

[0008] The sealing abutment assembly includes an elastic element that surrounds the lock hole to seal it. The elastic element has an abutment extending into the lock hole on its inner side, and the abutment is matched with the position of the T-shaped lock.

[0009] The mounting rod has a suction cup at its bottom, and the suction cup is detachably connected to the mounting rod.

[0010] The shooting stick has a rechargeable power supply inside, and the power output terminal of the rechargeable power supply is connected to a power control module. The power output terminal of the power control module is electrically connected to the power input terminal of the camera. The end of the shooting stick has a USB connector, which is electrically connected to the power supply of the rechargeable power supply.

[0011] The shooting pole is equipped with a light on its side, and the power input terminal of the light is electrically connected to the power output terminal of the power control module.

[0012] The shooting rod and the sealing block are detachably connected.

[0013] This invention features an ingenious structural design. When not in use, the shooting stick can be completely stored in the mounting rod, effectively protecting it from damage caused by accidental drops onto the ground, including the shooting stick, its circuitry, and the camera. Furthermore, when storing the shooting stick, air pressure is used to blow air onto the camera surface, cleaning away any adhering dust and ensuring the clarity of the camera's images during secondary use.

[0022] Camera 1, mounting rod 11, mounting slot 12, notch 13, sealing block 14, shooting rod 15, air outlet pipe 16, distribution pipe 17, nozzle 18, stepped hole 2, T-shaped lock 21, lock hole 22, spring 23, elastic element 24, stop element 25, suction cup 26, USB connector 27, lighting lamp 28. Detailed Implementation

[0023] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-6 As shown, a portable multimedia teaching aid of the present invention includes a camera 1 and a mounting rod 11. The mounting rod 11 has an upward-opening mounting groove 12 inside. The upper side of the mounting rod 11 has a notch 13 communicating with the mounting groove 12. A sealing block 14 is slidably and sealingly assembled in the mounting groove 12. A limit mechanism is assembled between the sealing block 14 and the mounting rod 11. A shooting rod 15 is rotatably assembled on the upper side of the sealing block 14 through a damping shaft. The camera 1 is located on the side of the shooting rod 15 away from the sealing block 14. The lower side of the mounting rod 11 has an air outlet pipe 16 communicating with the mounting groove 12. The upper end of the air outlet pipe 16 is connected to a distribution pipe 17. The distribution pipe 17 is assembled at the lower side of the notch 13. The distribution pipe 17 is equipped with a plurality of nozzles 18. The ends of the plurality of nozzles 18 away from the distribution pipe 18 are all deflected toward the notch 13.

[0025] When the teacher needs to use this equipment, the teacher can release the limit on the sealing block through the limiting mechanism. At this time, the teacher can directly pull the shooting rod 15 upward, so that the shooting rod 15 moves upward and drives the sealing block 14 to move upward in the mounting groove 12 until the sealing block 14 moves upward to the limit position. At this time, the teacher can rotate the shooting rod 15 until the shooting rod 15 and the mounting rod 11 are distributed at ninety degrees. Since the shooting rod 15 and the mounting rod 11 are connected by a damping shaft, when the shooting rod 15 is rotated to a suitable angle, the teacher can stop rotating the shooting rod 15 and automatically position the shooting rod 15 without easily causing angular deviation. At this time, the data can be placed under the camera 1 for data shooting.

[0026] When camera 1 is not in use, the shooting pole 15 can be rotated until it is vertically aligned with the mounting pole 11. After the limiting mechanism stops the sealing block 14, the operator can directly push the shooting pole 15 to retract it into the mounting groove 12. The sealing block 14 moves downward within the mounting groove 12 until the shooting pole 15 is fully retracted into the mounting pole 11. Then, the limiting mechanism stops the sealing block 14. This design allows the shooting pole 15 to be fully retracted into the mounting pole 11 when not in use, providing comprehensive protection for the shooting pole 15. It will not be damaged by accidental drops, nor will it damage the camera 15.

[0027] When the sealing block 14 moves upward, it can create a negative pressure on the lower side of the mounting groove 12. Outside air can be introduced into the distribution pipe 17 and the air outlet pipe 16 through the nozzle 18, and finally enter the interior of the mounting groove 12. When the sealing block 14 moves downward in the mounting groove 12, it can squeeze the space on the lower side of the mounting groove 12, and introduce the air on the lower side of the mounting groove 12 into several nozzles 18 through the distribution pipe 17 and the air outlet pipe 16, and then spray it out through several nozzles 18. Therefore, when storing the shooting pole 15, the surface on the side where the camera 1 is installed is cleaned to ensure the cleanliness of the surface of the camera 1 and to prevent it from affecting shooting during secondary use.

[0028] The limiting mechanism includes a stepped hole 2 on the side of the sealing block 14, a spring-loaded component in the stepped hole 2, and a T-shaped locking member 21 extending out of the stepped hole 2 connected to the spring-loaded component. The upper and lower sides of the mounting rod 11 are provided with locking holes 22 that communicate with the mounting groove 12. Both locking holes 22 are matched with the T-shaped locking member 21. The outer wall of the mounting rod 11 is provided with two sealing abutment components that are matched with the two locking holes 22 respectively.

[0029] The T-shaped locking piece 21 can be pushed out of the stepped hole 2 and locked into the lock hole 22 by the spring-loaded component. When the T-shaped locking piece 21 is locked into the lock hole 22, the sealing block 14 cannot slide up and down. When the sealing block 14 slides to the upper limit position and the lower limit position, it can match the position of the upper and lower lock holes 22 respectively. The teacher can push the T-shaped locking piece 21 out of the lock hole 22 by the sealing abutment component. After the T-shaped locking piece 21 is pushed out of the lock hole 22, the sealing block 14 can slide up and down.

[0030] The spring-rebound assembly includes a spring 23, which is disposed inside the stepped hole 2, and the other end of the spring 23 is connected to the T-shaped locking member 21.

[0031] When the sealing abutment assembly pushes the T-shaped lock 21 out of the lock hole 2, the spring 23 is compressed. When the sealing abutment assembly is released from the T-shaped lock 21, the spring 23 can extend and push the T-shaped lock 21 out of the stepped hole 2, allowing it to be locked into the lock hole 22.

[0032] The sealing abutment assembly includes an elastic element 24, which surrounds the lock hole 22 to seal the lock hole 22. The inner side of the elastic element 24 is provided with an abutment 25 that extends into the lock hole 22, and the abutment 25 matches the position of the T-shaped lock member 21.

[0033] When it is necessary to push the T-shaped lock 21 out of the lock hole 2, the teacher can directly press the elastic element 24. The elastic element 24 deforms, causing the abutment 25 to extend into the lock hole 22 and push the T-shaped lock 21 out of the lock hole 22, thereby canceling the limit. When the elastic element 24 is no longer pressed, the elastic element 24 resets itself, causing the abutment 25 to reset. Furthermore, due to the design of the elastic element 24 sealing the lock hole 2, the gas inside the mounting groove 12 cannot flow out to the outside through the lock hole 2.

[0034] The bottom of the mounting rod 11 is equipped with a suction cup 26, which is detachably connected to the mounting rod 11. When using this teaching aid, the teacher can use the suction cup 26 to attach it to the tabletop, thereby maintaining the stability of the mounting rod 11 on the tabletop.

[0035] The shooting stick 15 has a rechargeable power supply inside. The power output terminal of the rechargeable power supply is connected to a power control module. The power output terminal of the power control module is electrically connected to the power input terminal of the camera 1. The end of the shooting stick 15 has a USB connector 27, which is electrically connected to the rechargeable power supply.

[0036] This design places the circuitry within the shooting stick 15, protecting both the shooting stick 15 and the circuitry.

[0037] A light 28 is provided on the side of the shooting pole 15. The power input terminal of the light 28 is electrically connected to the power output terminal of the power control module. The light 28 is designed to illuminate the teacher's teaching materials, ensuring the clarity of the images captured by the camera 1.

[0038] The shooting pole 15 is detachably connected to the sealing block 14. This design allows the shooting pole 15 to be removed and replaced or maintained when needed.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
