Example Embodiment
[0023] Example 1
[0024] Such as Figure 1-5 The construction sand table for sales display shown includes a bearing platform 1, which is used to support the building sand table and store spare parts; the bearing platform 1 is fixedly installed with a bearing plate 2 at the upper end, and the bearing plate 2 is provided with a connecting A first groove 9 and a second groove 13 are installed in the first groove 9 with a first bevel gear rod 10 and a second bevel gear rod 11 that mesh with each other, and the second groove 13 is installed There is a turntable 15, which takes the first bevel gear rod 10 to rotate by rotating the turntable 15 so that the first bevel gear rod 10 rotates with the second bevel gear rod 11 vertically meshing with it; the second bevel gear The upper end of the rod 11 is fixedly installed with a support plate 3, and the second bevel gear rod 11 rotates with the support plate 3 fixedly connected at the upper end to rotate together; the upper end of the sup...
Example Embodiment
[0028] Example 2
[0029] The difference between this embodiment and the first embodiment is that a universal wheel 7 is installed at the bottom of the carrying platform 1, and the universal wheel 7 is arranged to facilitate the movement of the construction sand table; the universal wheel 7 is equipped with a foot brake 8 and the foot The brake 8 is convenient for fixing the construction sand table at any time.
[0030] The working principle is as follows: The construction sand table is moved to a suitable position by the universal wheel 7 and fixed by the foot brake 8. When it is necessary to rotate and observe, pull out the turntable 15 in the second groove 13, rotate the turntable 15 and pass the first cone The shape gear 10 and the second bevel gear 11 cooperate to make the support plate 3 take the building model 4 on the upper surface to rotate for display. The first slide groove 16 is set to cooperate with the first pulley 17 to reduce the friction when the support plate 3 ro...
