The fixed part oppresses the installation part to form elastic deformation to tightly press the first drive shaft, and thus the installation part is fixed on the first drive shaft.
Description
Technical field
The utility model relates to a kind of three surface-turning advertising placard, relates in particular to a kind of gearing of three surface-turning advertising placard.
Background technology
Three surface-turning advertising placard is made up of the triangular prism of a group and registration, triangular prism can be made by aluminium section bar, and it can rotate around self central shaft, three kinds of advertisement pictures are separately positioned on three faces of this group triangular prism, thereby utilize three sides of triangular prism can form three width of cloth pictures, rotating triangular prism is convertible advertisement picture.Therefore, three surface-turning advertising placard has the space that same area can three times of performances and the advantage of vision innervation.
Existing three surface-turning advertising placard is generally realized the rotation of described triangular prism by the driven by motor gearing, thereby realizes the function of its continuous conversion picture.As shown in Figure 1, the gearing 9 of existing three surface-turning advertising placard, it comprises one first transmission shaft 90, one second transmission shaft 92, one first power wheel 94 and that is connected first transmission shaft 90 is connected second power wheel 96 of second transmission shaft, this first transmission shaft 90 and the 92 vertical settings substantially of second transmission shaft, first transmission shaft 90 is used to connect motor (not shown), thereby provide gearing 9 power, this first power wheel 94 can drive second power wheel 96 and rotate, and driving second transmission shaft 92, the rotation of second power wheel 96 rotates, this second transmission shaft 92 is used to connect the triangular prism (not shown) of billboard, rotate thereby can drive triangular prism by the rotation of second transmission shaft 92, realize that gearing 9 drives the function that triangular prism rotates.
As shown in Figures 1 and 2, described first power wheel 94 can be made by one-body molded, it comprises the shoulder 942 of a portion of wheel 940 and a fifth wheel portion 940, and this is taken turns portion 940 and is provided with a groove 944 and a projection 946, this groove 944 and the projection 946 radially settings along first power wheel 94.These projection 946 trailing wheel portions 940 are outwards outstanding away from a side of shoulder 942, and roughly are circular-arc, and its two ends are provided with guiding face 948.The two lateral walls of this groove 944 is provided with guiding face 949, and roughly is Eight characters shape.One bolt 902 passes shoulder 942 and first transmission shaft 90 and is spirally connected with a nut 904, thereby described first power wheel 94 is fixed on first transmission shaft 90.
As Fig. 1 and shown in Figure 3, described second power wheel 96 comprises one first gear 960 and one second gear 962, this first and second gear 960,962 has the tooth 964,966 that three equal angles are provided with at interval respectively, and first and second gear 960,962 difference shape roughly triangular in shape.This first and second gear 960,962 is provided with along its center line overlap, and six teeth 964,966 are provided with at interval for equal angles.
As shown in Figure 4, the projection 946 of described first power wheel 94 can promote the tooth 964 of first gear 960, rotate thereby promote second power wheel 96, the groove 944 of described first power wheel 94 then can cooperate and drive the tooth 966 of second gear 962 with its sidewall, rotates thereby drive second power wheel 96.When groove 944 and protruding 946 does not mesh with first and second gears 960,962 respectively, as shown in Figure 5, second gear 962 has the side of two teeth 966 against first power wheel 94, and this moment, second transmission shaft 92 and triangular prism stopped operating, and can view and admire the picture of billboard for spectators.And after groove 944 and protruding 946 is finished once engagement with first and second gears 960,962 respectively, second power wheel 96 and second transmission shaft 92 roughly rotate 120 °, thereby triangular prism has also rotated 120 °, just former advertisement picture can be replaced with another width of cloth.
Yet, three surface-turning advertising placard in use for some time, owing to reasons such as wearing and tearing and distortion, the gap of first power wheel 94 and second power wheel 96 can increase, can not realize that second gear 962 as shown in Figure 5 has the side of 966 whiles of two teeth against first power wheel 94, and make second transmission shaft 92 and triangular prism set stop operating during, can produce and rock, and make all triangular prisms can't be in simultaneously in the plane towards spectators' the side, thereby the picture expression effect of billboard is relatively poor, is unfavorable for that spectators view and admire.
For overcoming the problems referred to above, must in time the gap of first power wheel 94 and second power wheel 96 be adjusted, make that second gear 962 has the side of two teeth 966 against first power wheel 94, as shown in Figure 5 during the stopping operating of second transmission shaft of setting 92 and triangular prism.Existingly described first power wheel 94 is fixed on mode on first transmission shaft 90 by bolt 902 and nut 904, be not easy to first power wheel 94 axially moving along first transmission shaft 90 to adjust the gap of first power wheel 94 and second power wheel 96, even with first power wheel 94 axially moving along first transmission shaft 90, also need first transmission shaft 92 is punched again, this not only increases the degree of difficulty of maintenance, but also weakened the intensity of first transmission shaft 92, cause the damage of first transmission shaft 92 easily, also therefore, can not with first power wheel 94 along first transmission shaft 90 axially carry out repeatedly move.So the fixed form of above-mentioned first power wheel 94 is not easy to three surface-turning advertising placard be keeped in repair or maintains, and need improve in the future.
