Abstract
The utility model provides a triangular prism progressive transmission device of three side-turning advertising board, comprising a step cam comprising two half blocks and an aluminum shaft fixing round hole, wherein one half block comprises two round nut positioning lug bosses and two square nut positioning lug bosses, the other half block comprises two round screw positioning grooves and two square screw positioning grooves, and one side of the step cam is provided with a triangular shifting block completely meshed with a small triangle block at the lower end of a triangular block. The transmission device is characterized in that both sides of the two half blocks are provided with regular shrinkage pool. Due to the adoption of the structure, the utility model has the advantages of good transmission, low cost and convenient replacement compared with the prior art.
Description
Technical field
The utility model relates to a kind of three surface-turning advertising placard display unit, relates in particular to a kind of three surface-turning advertising placard tri-prism stepping transmission device.
Background technique
China Patent No. is 200620055010.6 to disclose a kind of three reversing advertisement board stepping cams and change easier and do not destroy the tri-prism stepping transmission device of whole transmission shaft rigidity, and it comprises: whole transmission shaft, coupling, split type are with bolted stepping cam, big up and small down step-like triangle shifting block; 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; One end of stepping cam is provided with boss vertically, and the coupling key is protruding, and the one end is set on the described boss, and fixedlys connected with the latter; Have the protruding the other end of key and be set on the whole transmission shaft that has keyway, the protruding sleeve of described key is in described keyway.Two half blocks of this stepping cam are only fixed by two screw holes and screw, and the boss of stepping cam is shape of threads, in order to reinforce two half blocks, also need increase a bolt to clamp two half blocks, this had both increased the cost of stepping cam, had brought inconvenience for its replacing again.
The model utility content
The purpose of this utility model is in order to solve above-mentioned the deficiencies in the prior art, easily, not destroy whole transmission device rigidity and stable three surface-turning advertising placard tri-prism stepping transmission device and provide a kind of stepping cam to change.
The purpose of this utility model realizes by following scheme: three surface-turning advertising placard tri-prism stepping transmission device, comprise by the half block that is provided with two round nut positioning boss and two square nut positioning boss and be provided with stepping cam that the half block of two circular screw positioning grooves and two square screw positioning grooves forms and the fixing circular hole of aluminium axle.
Described stepping cam one side is provided with the triangle shifting block that meshes fully with the little corner block in corner block lower end, it is characterized in that described two half block both sides are provided with the shrinkage pool of rule.
Described stepping cam is provided with two round nut positioning boss and two square nut positioning boss and two circular screw positioning grooves and two square screw positioning grooves, and two round nut positioning boss and two square nut positioning boss are set in two circular screw positioning grooves and two square screw positioning grooves respectively.Described two round nut positioning boss and two all built-in set screw nuts of square nut positioning boss; Described two circular screw positioning grooves and two square screw positioning grooves are equipped with screw hole, and two half blocks are connected and fixed by socket head screw by these four screw holes, and screw hole is provided with rubber stopper, and screw is sealed in the hole preferably.
Described aluminium axle fixedly is provided with groove in the circular hole, is higher than on the circular hole wall of groove part to establish lines or friction points.
Be provided with the convex scale of rule one week of surface of described stepping cam, in order to regulate the angle and the validity of reversing advertisement board tri-prism.
The utility model is owing to adopted said structure, two half block both sides are provided with the shrinkage pool of rule, not only attractive in appearance and reduced cost of material, guaranteed that also the stepping cam shrinks evenly, stepping cam fixed screw holes is provided with rubber stopper, makes screw be sealed in the hole preferably, so that prolong screw working life, the aluminium axle fixedly is higher than in the circular hole on the circular hole wall of groove part establishes lines or friction points, so that increase the aluminium axle with the fixedly friction ractor and the intensity of circular hole, realizes transmission better.The utility model has compared with prior art that transmission is good, cost is low, change advantage easily.
Description of drawings
Fig. 1 is the utility model parts explosion;
Fig. 2 is the parts explosion of another angle of the utility model;
Fig. 3 is the utility model transmission schematic representation.
Concrete case study on implementation
The utility model is described in further detail below in conjunction with accompanying drawing: Fig. 1, three surface-turning advertising placard tri-prism stepping transmission device among Fig. 2 and Fig. 3, comprise the stepping cam of forming by the half block that is provided with two round nut positioning boss 9 and two square nut positioning boss 10 and two circular screw positioning grooves 11 and two square screw positioning grooves 12 1, the aluminium axle is circular hole 2 fixedly, described stepping cam one side is provided with the triangle shifting block 3 that meshes fully with the little corner block in corner block lower end, described two half block both sides are provided with the shrinkage pool 4 of rule, described stepping cam is provided with four screw holes 5, two half blocks are connected and fixed by socket head screw by these four screw holes, and screw hole is provided with rubber stopper 6, make screw be sealed in the hole preferably, so that prolong screw working life, described aluminium axle fixedly is provided with groove 7 in the circular hole 2, be higher than on the circular hole wall of groove part and can establish lines or friction points, so that increase aluminium the axle same fixedly friction ractor and the intensity of circular hole, realize transmission better, be provided with the convex scale 8 of rule one week of surface of described stepping cam, in order to regulate the angle and the validity of reversing advertisement board tri-prism.
More than be the utility model one specific embodiment, yet those of ordinary skill in the art still can make and not break away from scheme of the present utility model and still fall into protection domain of the present utility model.
