[0023] Please see Figures 1 to 4 This utility model provides an outdoor teaching aid, which includes a chassis 10, a support frame 20 mounted on the chassis 10, an adjustment seat 30 slidably mounted on the support frame 20, a first adjustment component 40 connecting the support frame 20 and the adjustment seat 30, a positioning seat 50, a second adjustment component 60 connecting the positioning seat 50 and the adjustment seat 30, a handwriting board 70 that can be freely attached and detached from the adjustment seat 30, and two sets of fixing components 80 mounted on both sides of the adjustment seat 30. The first adjustment component 40 can adjust the adjustment seat 30 in the axial direction of the support frame 20. During the adjustment process, the adjustment seat 30 drives the positioning seat 50 and the handwriting board 70 mounted on the positioning seat 50 to adjust synchronously. The second adjustment component drives the positioning seat 50 to adjust its angle in the circumferential direction.

[0024] The support frame 20 includes two support rods 21 vertically connected to the chassis 10 and a fixing plate 22 fixedly installed on the top of the support rods 21.

[0025] The adjusting seat 30 is provided with a first adjusting cavity 31 and a second adjusting cavity 32 on both sides, and the adjusting seat 30 is provided with two support plates 33 at the front and rear sides of the second adjusting cavity 32. In addition, the adjusting seat 30 is also provided with two adjusting holes 34, which penetrate the adjusting seat 30 in the vertical direction.

[0026] The first adjustment component 40 includes a lead screw 41 and a rotating wheel 42. The outer surface of the lead screw 41 is provided with an external thread, and the rotating wheel 42 is provided with a through hole 421. The wall of the through hole 421 is provided with an internal thread.

[0027] The positioning seat 50 includes a positioning plate 51, a positioning part 52 connected to the rear side of the positioning plate 51, and an adjusting part 53 installed on the positioning part 52. The positioning plate 51 is provided with a positioning groove 511, which extends downward from the upper end of the positioning plate 51. The positioning groove 511 is wider inside and narrower outside, and extends to the front side of the positioning plate 51. The outer side structure of the adjusting part 53 is similar to that of a turbine structure, and the outer side of the adjusting part 53 has locking teeth.

[0028] The second adjustment component 60 includes a rotating shaft 61 and a handwheel 62. The handwheel 62 is provided with an adjustment rod, the structure of which is similar to that of a worm gear. The outer surface of the adjustment rod 621 is provided with rotating teeth. The back of the handwriting tablet 70 is provided with a locking block 71, the cross-section of which is T-shaped.

[0029] During assembly, the two support rods 21 of the support frame 20 pass through the two adjustment holes 34 of the adjustment seat 30, allowing the adjustment seat 30 to slide along the support rods 21. The rotating wheel 42 of the first adjustment assembly 40 extends into the first adjustment cavity 31 of the adjustment seat 30. One end of the lead screw 41 of the first adjustment assembly 40 is fixed to the fixing plate 22 of the support frame 20, and the other end of the lead screw 41 passes through the through hole 421 of the adjustment seat 30 and the rotating wheel 42. The external thread of the lead screw 41 engages with the internal thread of the through hole 421. When the rotating wheel 42 is rotated, the rotating wheel 42, through its engagement with the lead screw 41, drives the adjustment seat 30 to adjust along the support rod 21.

[0030] The rotating shaft 61 of the second adjustment component 60 passes through both the support plate 33 of the adjustment seat 30 and the positioning part 52 of the positioning seat 50. The adjustment rod 621 of the handwheel 62 passes through the adjustment seat 30 and is secured to the upper end face of the adjustment seat 30 by a fixing member (not shown). The rotating teeth on the handwheel 62 are placed in the second adjustment cavity 32. The rotating teeth on the adjustment rod 621 mesh with the locking teeth of the adjustment part 53. When the handwheel 62 is rotated, the positioning seat 50 is adjusted in the circumferential direction through the cooperation of the rotating teeth and the locking teeth. The locking block 71 on the back of the writing tablet 70 is inserted into the positioning groove 511 of the positioning plate 51 from above or moved upward and removed from the positioning groove 511.

[0031] Each set of fixing components 80 includes a guide sleeve 82, a guide piece 81 passing through the guide sleeve 82, a pin 83 passing through the guide piece 81 and fixed to the adjusting seat 30, a suction cup 85, a connecting piece 84 connected to the suction cup 85, an adjusting shaft 87 passing through both the guide sleeve 82 and the connecting piece 84, and a positioning pin 86 mounted on the guide sleeve 82 and capable of limiting the guide piece 81. The guide sleeve 82 is provided with a sliding groove 821 that axially penetrates the entire guide sleeve 82. The guide sleeve 82 is provided with a positioning post 822 and an inner hole 823 that extends inward from the outer side of the positioning post 822 to the sliding groove 821. The inner hole 823 has an internal thread on its wall, and the outer side of the pin 83 has an external thread corresponding to the internal thread on the inner hole 823. The guide sleeve 82 is provided with a clearance opening 824 at the end near the suction nozzle.

[0032] During assembly, the pin 83 passes through the end of the guide plate 81 away from the guide sleeve 82 and is fixed on the adjusting seat 30. The guide plate 81 can rotate around the pin 83. The guide plate 81 is inserted into the slide groove 821 of the guide sleeve 82. The positioning pin 86 is installed on the positioning post 822 by means of threaded installation. The connecting piece 84 is inserted into the relief opening 824 of the guide sleeve 82. The adjusting shaft 87 passes through both the guide sleeve 82 and the connecting piece 84. The connecting piece 84 and the suction cup 85 can be rotated and adjusted.

[0033] In use, first adjust the height of the positioning seat 50 using the first adjustment component 40. After adjustment, rotate the positioning pin 86 to loosen the guide plate 81, adjust the suction cup 85, and attach the suction cup 85 to the table surface used to support the outdoor teaching aid. During the adjustment process, the guide sleeve 82 can be adjusted on the guide plate 81, and the connecting piece 84 rotates and adjusts simultaneously. After the suction cup 85 is fixed, rotate the positioning pin 86 in the opposite direction to press the guide plate 81 tightly.

[0034] The beneficial effects of this utility model of outdoor teaching aid are as follows: By setting a fixing component 80, the guide plate 81 and suction cup 85 of the fixing component 80 can be rotated and adjusted according to the height of the adjusting seat 30. The guide plate 81 can be extended and retracted on the guide sleeve 82, thereby allowing the fixing component 80 to be adjusted according to the height of the adjusting seat 30, so that the suction cup 85 can be attached to the table surface. The positioning pin 86 locks the adjusted guide plate 81. The entire fixing component 80, support frame 20 and adjusting seat 30 form a triangular frame structure, which effectively prevents the support frame 20 from shifting and shaking, and improves the practicality of the outdoor teaching aid.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
