Specific embodiments

[0022] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0023] Embodiment 1

[0024] As Figures 1 to 4 shown, this embodiment proposes a multifunctional teaching demonstration device for higher mathematics space coordinates, including a plane frame 1, a first folding surface 2 is hinged on the upper surface of the plane frame 1, and a second folding surface 3 hinged to the first folding surface 2; a limit frame 4 for limiting and blocking the first folding surface 2 and the second folding surface 3 is fixedly connected to the outer surface of the plane frame 1, and a first locking component connected to the first folding surface 2 is arranged on the outer surface of the limit frame 4, and the first locking component is used for limiting and locking or releasing the first folding surface 2; a second locking component connected to the second folding surface 3 is arranged on the outer surface of the plane frame 1, and the second locking component is used for limiting and locking or releasing the second folding surface 3.

[0025] In this embodiment, referring to Figures 1 through 4, The arrangement of the first locking component and the second locking component facilitates locking after the first folding surface 2 and the second folding surface 3 are folded in sequence, keeping the first folding surface 2 and the second folding surface 3 perpendicular to the flat frame 1, thus facilitating the establishment of the Z-axis coordinate. Moreover, the first folding surface 2 and the second folding surface 3 are perpendicular to each other after being unfolded, enabling the establishment of the X and Y-axis coordinates.

[0026] The first locking component includes a limit block 5 fixed on the outer surface of the limit frame 4, a clamping plate 6 fixed on the outer surface of the first folding surface 2, and a first clamping rod 7 that is slidably engaged with the reserved hole on the upper surface of the limit block 5 and is clamped with the clamping plate 6. By providing the clamping plate 6, it is convenient to be clamped and locked with the first clamping rod 7, so that the first folding surface 2 can be locked after being manually unfolded by the first clamping rod 7. And the first folding surface 2 can be limited and blocked by the limit frame 4 after being unfolded, and then can be perpendicular to the flat frame 1.

[0027] Furthermore, the first folding surface 2 is vertically locked by the first locking component, facilitating subsequent space teaching. And the sliding between the first clamping rod 7 and the limit block 5 has damping, which can greatly improve the locking effect on the first folding surface 2, and greatly improve the space utilization rate and the convenience of carrying.

[0028] The first locking component further includes a first telescopic spring 8 sleeved on the outer surface of the first clamping rod 7 and connected to the limit block 5. The first telescopic spring 8 is used to drive the first clamping rod 7 to automatically rebound to lock the first folding surface 2. By providing the first telescopic spring 8, it can automatically push the first clamping rod 7 to rise at the limit block 5, and then facilitate automatically inserting the first clamping rod 7 into the reserved hole of the clamping plate 6 to lock the first folding surface 2.

[0029] When unlocking, only need to pull down the convex ring at the lower end of the first clamping rod 7 to unlock the first folding surface 2, thus greatly improving the convenience and practicality of folding the first folding surface 2.

[0030] The second locking component includes a sliding rod 9 fixed on the outer surface of the flat frame 1 and a sliding plate 10 slidably engaged with the sliding rod 9. A second clamping rod 11 fixedly connected to the outer surface of the sliding plate 10 is clamped with the reserved hole on the outer surface of the second folding surface 3.

[0031] By providing the sliding rod 9, it is better to facilitate the limited sliding of the sliding plate 10 at the sliding rod 9, and enable the sliding plate 10 to be clamped and locked by inserting the second clamping rod 11 into the reserved hole on the outer surface of the second folding surface 3 after being unfolded during sliding, thus avoiding the situation of deviation and shaking of the second folding surface 3 and the first folding surface 2 when establishing the space coordinate system. And the sliding between the sliding plate 10 and the sliding rod 9 has damping, which can greatly improve the locking effect on the second folding surface 3.

[0032] The second locking component further includes a second telescopic spring 12 sleeved on the outer surface of the sliding rod 9 and connected to the sliding plate 10. The second telescopic spring 12 is used to drive the sliding plate 10 to automatically rebound and lock the second folding surface 3. By setting the second telescopic spring 12, the sliding plate 10 can be automatically pushed to lock the second folding surface 3 with the second locking rod 11, thus eliminating the need for manual locking operation of the second folding surface 3 and greatly improving convenience.

[0033] Moreover, it can also improve the convenience of unlocking the second folding surface 3. Only by pulling the sliding plate 10 outwards can the locking effect on the second folding surface 3 be released, thus facilitating the folding of the second folding surface 3 to the first folding surface 2.

[0034] Embodiment 2

[0035] As Figures 1 to 4 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that the outer surfaces of the first folding surface 2 and the second folding surface 3 are respectively provided with a first grid scale line 13 and a second grid scale line 14. The upper part of the plane frame 1 is provided with an irradiation projection module 16. The outer surface of the irradiation projection module 16 is provided with three irradiation lamps 17. The three irradiation lamps 17 project the irradiated light onto the first folding surface 2, the second folding surface 3, and the connection between the first folding surface 2 and the second folding surface 3. The irradiation lamps 17 are used to display the spatial coordinates of X, Y, and Z at the first grid scale line 13 and the second grid scale line 14; the upper part of the plane frame 1 is provided with an adjustment component connected to the irradiation projection module 16.

[0036] In this embodiment, referring to Figures 1 through 4 , the settings of the first grid scale line 13 and the second grid scale line 14 can facilitate the display of scales after the X, Y, and Z spatial coordinate systems are established, and can cooperate with the irradiation lamps 17 so that the light irradiated by the irradiation lamps 17 can irradiate onto the surfaces of the first folding surface 2 and the second folding surface 3, thus facilitating the display of the spatial coordinate points of the X, Y, and Z axes through the first grid scale line 13 and the second grid scale line 14, thereby realizing the teaching of spatial geometry.

[0037] The adjustment component includes a telescopic rod 15 connected to the irradiation projection module 16. The telescopic rod 15 is used to adjust the height of the irradiated light of the irradiation lamp 17 in the Z-axis direction. By setting the telescopic rod 15, the telescopic rod 15 has a manual telescopic function, so that the irradiation projection module 16 and the irradiation lamp 17 can be pushed for height adjustment, thus facilitating the adjustment of the Z-axis position during spatial teaching.

[0038] The upper surface of the planar frame 1 is inlaid with a magnetic plate 19. The lower end of the telescopic rod 15 is fixedly connected with a magnetic ring 18. The upper surface of the magnetic plate 19 is fixedly connected with a laminate 20 that contacts the magnetic ring 18. By providing the magnetic plate 19 and the magnetic ring 18, the magnetic plate 19 and the magnetic ring 18 magnetically attract each other, so that it is convenient to adsorb and place components such as the telescopic rod 15 on the magnetic plate 19 through the magnetic ring 18.

[0039] Moreover, it is convenient to move the telescopic rod 15 on the magnetic plate 19, so that it is convenient to move the irradiation lamp 17 in the X and Y axes with respect to the first folding surface 2 and the second folding surface 3, facilitating the work of spatial coordinate teaching. The provision of the laminate 20 enables the magnetic ring 18 and the telescopic rod 15 to be placed at the laminate 20 more conveniently, enhancing the smooth stability during movement.

[0040] Threaded foot supports 21 are installed at the four corners of the bottom surface of the planar frame 1, and a spirit level 22 is installed on the upper surface of the irradiation projection module 16. By providing the threaded foot supports 21, it is convenient to adjust the horizontal position of the overall device placed on a plane. Then, the spirit level 22 is used to observe whether the device is in a horizontal state, and further adjust it to the horizontal position according to the threaded foot supports 21, facilitating subsequent spatial teaching work and greatly enhancing the practicality of the overall device.

[0041] Working principle: During the teaching of spatial geometry in advanced mathematics, first place the overall device on a plane through the threaded foot supports 21. Then, through the mutual cooperation of the threaded foot supports 21 and the spirit level 22, adjust the overall device to a horizontal state. The irradiation lamp 17 emits light that irradiates on the surfaces of the first folding surface 2 and the second folding surface 3, thus establishing a spatial coordinate system. The first grid scale line 13 and the second grid scale line 14 can be used to observe the coordinate points on the X, Y, and Z axes. The telescopic rod 15 can be extended and retracted to adjust the height of the Z-axis irradiation coordinate point. Through the mutual cooperation of the magnetic plate 19 and the magnetic ring 18, it is convenient to stably place the telescopic rod 15 on the surface of the laminate 20. Furthermore, due to the magnetic attraction between the magnetic plate 19 and the magnetic ring 18, the telescopic rod 15 can be moved to different positions on the surface of the laminate 20, so as to adjust the positions of the coordinate points on the X, Y, and Z axes according to requirements, facilitating spatial teaching.

[0042] After the space teaching is completed, first take out the telescopic rod 15, the irradiation and projection module 16, and the irradiation lamp 17. Then, by pulling the sliding plate 10 outward, the sliding plate 10 is limited to slide at the sliding rod 9, so that the locking of the second folding surface 3 is released by the second clamping rod 11, and the second folding surface 3 is folded to contact the first folding surface 2. At this time, by pulling the first clamping rod 7 downward, the locking of the first folding surface 2 is released by the first clamping rod 7, and then the first folding surface 2 and the second folding surface 3 are folded into the storage groove on the plane frame 1, so as to realize the folding of the whole device and facilitate the carrying of the whole device.

[0043] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
