Technical Field

[0001] This utility model relates to the field of teaching device technology, specifically to a teaching demonstration device. Background Technology

[0002] Most existing teaching demonstration devices are equipped with display screens to assist teaching. However, the display screens in existing teaching demonstration devices are easily affected by external light, which can lead to problems such as glare on the surface of the display device and unclear viewing. This is not conducive to the display of teaching pictures and affects the teaching effect. Utility Model Content

[0003] This invention provides a teaching demonstration device that overcomes the defect in existing teaching demonstration devices where surface reflection affects the teaching demonstration.

[0004] According to the present invention, a teaching display device includes a device body, the device body includes a display component, and a winding mechanism is provided at the display component; the winding mechanism includes an extendable shielding cloth for blocking external light, and a limiting component is provided at the winding mechanism for positioning the shielding cloth after it has been extended.

[0005] Compared with existing technologies, using a shielding cloth to block external light reduces the impact of external light on the exhibits, thereby improving the teaching effect of the device. In addition, using flexible and rollable items like shielding cloth makes it easy to store the exhibits later and reduces the space occupied.

[0006] Preferably, the winding mechanism also includes a winding frame that can be detachably mounted on both sides of the outer wall of the display piece. The outer wall of the winding frame away from the display piece has a storage groove. A storage roller is rotatably mounted in the storage groove along the height direction. The covering cloth is wound up on the outer wall of the storage roller.

[0007] In this invention, a rotating storage roller can roll up the covering cloth, enabling quick storage of the covering cloth while taking up less space after storage.

[0008] Preferably, the outer wall of the winding frame has protruding blocks at both the upper and lower ends, and the outer wall of the protruding blocks is provided with a support rod that can be rotated. The support rod and the shielding cloth are detachably installed.

[0009] In this invention, the angle of the covering cloth can be adjusted by rotating the support rod, and the detachable design of the support rod and the covering cloth will not affect the normal storage of the covering cloth.

[0010] Preferably, the support rod includes a rotating block rotatably disposed with respect to the outer wall of the protruding block and a support block rotatably connected to the rotating block.

[0011] In this invention, the support block is rotated so that it is parallel to the storage roller, thereby folding and storing the support rod. Furthermore, the rotation of the support block and the rotating block has a certain resistance, which ensures that the support block can be folded upwards.

[0012] Preferably, the outer wall of the winding rack has support portions at both ends, which are used to limit and support the support blocks.

[0013] In this invention, the rotating part of the rotating block and the supporting block is located on the outer wall of the supporting part, thereby preventing the rotating block and the supporting block from rotating and tilting under external force when supporting and limiting the cover cloth, which would affect the effect of supporting and limiting the cover cloth, thus achieving stable support for the cover cloth.

[0014] Preferably, the end of the shielding cloth is formed with a sleeve portion, and a sleeve cavity is formed at the sleeve portion. The outer wall end of the support block is provided with a push hole, and the push hole is threaded with an insertion block for insertion into the sleeve cavity.

[0015] In this invention, when the shielding cloth is in the winding state, the insert block is pushed forward towards the receiving roller to press the shielding cloth, which can press and limit the winding shielding cloth to achieve positioning of the shielding cloth in different shapes.

[0016] Preferably, a positioning screw hole is provided on the upper part of the outer wall of the protruding block, and a pressing element for pressing and positioning the rotating block is provided in the internal thread of the positioning screw hole.

[0017] In this invention, rotating the pressing component into the internal thread of the positioning screw hole can press and limit the rotating block, thereby limiting the rotation angle of the support rod. Attached Figure Description

[0023] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0024] Example 1

[0025] like Figure 1 As shown, this embodiment provides a teaching demonstration device, which includes a device body 100. The device body 100 includes a display component 110, and a winding mechanism 120 is provided at the display component 110. The winding mechanism 120 includes an extendable shielding cloth 121 for blocking external light, and a limiting component 122 is provided at the winding mechanism 120 for positioning the shielding cloth 121 after it is extended.

[0026] This application discloses a teaching demonstration device. When conducting ideological and political education, the shielding cloth 121 is extended, and the extended shielding cloth 121 is limited by the limiting member 122, which can block the external light on both sides of the display piece 110. Compared with the prior art, the shielding cloth 121 blocks the external light, thereby reducing the influence of external light on the display piece 110 and improving the teaching effect of the device. In addition, the shielding cloth 121 is a flexible and rollable item, which facilitates subsequent storage and reduces the area occupied.

[0027] Combination Figure 1-4 As shown, in this embodiment, the winding mechanism 120 also includes a winding frame 310 detachably disposed on both sides of the outer wall of the display piece 110. A storage groove 410 is provided on the outer wall of the winding frame 310 away from the display piece 110. A storage roller 420 is rotatably disposed in the storage groove 410 along the height direction. The shielding cloth 121 is wound up on the outer wall of the storage roller 420. Protrusions 510 are formed at the upper and lower ends of the outer wall of the winding frame 310. A support rod 320 is rotatably disposed on the outer wall of the protrusions 510. The support rod 320 and the shielding cloth 121 are detachably disposed.

[0028] With the above structure, when there is no need to block external light, rotating the storage roller 420 can roll up the shielding cloth 121, achieving quick storage of the shielding cloth 121. At the same time, the stored shielding cloth 121 occupies less space. Meanwhile, by connecting and installing the support rod 320 to the shielding cloth 121, the shielding angle of the shielding cloth 121 can be adjusted by rotating the support rod 320. The detachable setting of the support rod 320 and the shielding cloth 121 will not affect the normal storage of the shielding cloth 121.

[0029] Combination Figure 3-5 As shown, in this embodiment, the support rod 320 includes a rotating block 430 rotatably disposed with the outer wall of the protruding block 510 and a support block 440 rotatably connected to the rotating block 430; support portions 540 are formed at both ends of the outer wall of the winding frame 310, and the support portions 540 are used to limit and support the support block 440.

[0030] With the above structure, when the shielding cloth 121 is in the stored state, the support block 440 is rotated so that the support block 440 is parallel to the storage roller 420, thereby folding and storing the support rod 320. The rotation of the rotating block 430 and the support block 440 has a certain resistance, which can ensure that the support block 440 can be folded upward. At the same time, when the support rod 320 supports and limits the shielding cloth 121, the rotation point of the rotating block 430 and the support block 440 will be located at the outer wall of the support part 540, thereby preventing the rotating block 430 and the support block 440 from rotating together. This avoids the support block 440 being rotated and tilted by external force when supporting and limiting the shielding cloth 121, which would affect the effect of supporting and limiting the shielding cloth 121, thus achieving stable support for the shielding cloth 121.

[0031] Combination Figure 4-5 As shown, in this embodiment, the end of the shielding cloth 121 is formed with a sleeve portion 450, and a sleeve cavity 460 is formed at the sleeve portion 450. The outer wall end of the support block 440 is provided with a push hole 470, and the push hole 470 is provided with an insert block 480 for inserting into the sleeve cavity 460. The upper part of the outer wall of the protruding block 510 is provided with a positioning screw hole 520, and the positioning screw hole 520 is provided with a pressing member 530 for pressing and positioning the rotating block 430.

[0032] With the above structure, the insert block 480 in the rotating push hole 470 is inserted into the socket cavity 460 at the socket part 450, which can realize the detachable setting of the support rod 320 and the shielding cloth 121. In addition, when the shielding cloth 121 is in the winding state, pushing the insert block 480 towards the receiving roller 420 to press the shielding cloth 121 can press and limit the winding shielding cloth 121, realizing the positioning of the shielding cloth 121 in different shapes. At the same time, rotating the pressing member 530 into the positioning screw hole 520 can press and limit the rotating block 430, thereby limiting the rotation angle of the support rod 320.

[0033] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

[0034] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
