Description
Technical field
The utility model relates to a kind of advertisement display, especially relates to a kind of single tri-prism stepping transmission device of three reversing advertisement boards.
Background technique
As shown in Figure 5, the single tri-prism stepping transmission device of three reversing advertisement boards, this apparatus structure is simple, compact, have easy for installation, compact structure, convenient characteristics of regulating, by the stepping cam 4 of fixed cover on whole transmission shaft 5, be fixedly mounted on coaxial and form perpendicular to the triangle shifting block 6 of the shaft end of whole transmission shaft 5 with tri-prism, big up and small down step-like of triangle shifting block 6, radially be provided with a groove at stepping cam 4, can mesh with the big triangle shifting block in the upper strata of triangle shifting block 6, stepping cam 4 be axially arranged with a projection, this projection is stirred the little triangle shifting block of lower floor of triangle shifting block 6, stirs one side thereby make stepping cam 4 rotate a circle tri-prism.
As shown in Figure 6, stepping cam 4 is a split type, forms by 41 and 42 two, be respectively equipped with bolt hole 411 and 421 on it, when stepping cam 4 is installed with whole transmission shaft 5, only need to be enclosed within on the whole transmission shaft 5 41 and 42 respectively, be connected with 42 two 41 by bolt then; The fixed installation of stepping cam 4 and whole transmission shaft 5 is by in the axial punching of stepping cam 4 and penetrate whole transmission shaft 5 tapping screw radially and realize.
Because the more whole transmission shaft of stepping cam 4 wearing and tearing 5 is fast, stepping cam 4 adopts plastics and nylon mostly in addition, and whole transmission shaft 5 adopts aluminum alloys and installing and locating also complicated, and from making and install two aspects, it is 5 more reasonable than changing whole transmission shaft to change stepping cam 4.The structure of this split type is the replacing of stepping cam 4 condition of providing convenience, and repeatedly changes the hidden danger that the whole transmission shaft in stepping cam 4 backs 5 is destroyed and intensity reduces (it on quilt drilled a plurality of holes) yet also brought.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of stepping cam and changes three easier, as not destroy whole transmission shaft rigidity reversing advertisement board tri-prism stepping transmission devices.
Its technological scheme that solves its technical problem is: the tri-prism stepping transmission device of three reversing advertisement boards of split type, form with bolted stepping cam, big up and small down step-like triangle shifting block by whole transmission shaft, coupling, split type; Described stepping cam is by the half block that is provided with pin and bolt hole and be provided with pin-and-hole and the half block of bolt hole is formed; The stepping cam be axially arranged with boss, it is protruding that coupling is provided with key; Described coupling one end is set on the described boss, and described boss is fixedly connected, and the protruding the other end of band key is set on the whole transmission shaft that has keyway, and the protruding sleeve of its key is in described keyway.
As improvement of the present utility model, described coupling is pressed with alert and resourceful screw outward.
As further improvement of the utility model, described boss and coupling are step-like.
Advance one to go on foot improvement again as of the present utility model, have circular groove on the described step-like boss.
That the utility model not only has is easy for installation, compact structure, convenient characteristics of regulating, accurate positioning when setting up pin and with pin-and-hole the two halves of subdivision being connected; Set up coupling, not only make the connection of stepping cam and whole transmission easy, also do not destroy the rigidity of whole transmission shaft.

Embodiment
As shown in Figure 3 and Figure 4, three reversing advertisement board tri-prisms of split type stepping transmission device, the stepping cam of being made with bolted nylon by the whole transmission shaft 3 of aluminum alloy, coupling 2, split type 1, big up and small down step-like triangle shifting block 6 are formed; Referring to Fig. 1 and Fig. 2, stepping cam 1 is by the half block 11 that is provided with pin 111 and bolt hole 112 and be provided with pin-and-hole 122 and the half block 12 of bolt hole 121 is formed; Stepping cam 1 be axially arranged with a boss 10; It is protruding 20 that described coupling 2 is provided with key, and the one end is set on the described boss 10, fixedlys connected with described boss 10; The other end that has key protruding 20 is set on the whole transmission shaft 3 that has keyway, and its key protruding (20) sleeve is in described keyway.Described boss 10 and coupling 2 are step-like, have circular groove on the step-like boss 10.
Stepping cam 1 is fixing with coupling 2, adopts the mode of the quick screw of pressing machine outside coupling 2.Two sections, the alert and resourceful screw of every section radial symmetric about the outside of described coupling (2) is pressed with vertically, press by in the circular groove of alert and resourceful screw (22) on boss 10, coupling (2) is fixedlyed connected with described boss (10), by alert and resourceful screw (a 21) pressure transmission shaft (3), have the protruding the other end of key and whole transmission shaft (3) and strengthen fixing.Also can adopt as the mode of using tapping screw in the background technique.
In actual use, the abrasion condition of each tri-prism stepping transmission device is inconsistent, can't need simultaneously to change; And, stepping cam 1 is more easy to wear than coupling 2, adopts split type stepping cam 1, only need dismantle alert and resourceful screw or tapping screw during maintenance, just stepping cam 1 and coupling 2 can be separated, dismantle the half block 11 of connection stepping cam 1 and the bolt of half block 12 again and just described two half blocks can be taken off.Contrary above-mentioned steps operation just can replace new stepping cam 1 to get on, and is convenient and flexible.
