A kind of body of rod connects universal joint
Technical field
The utility model relates to driving mechanism, relates in particular to a kind of body of rod and connects universal joint.
Background technique
Universal joint is a kind of member of realizing the angle transmission of power, is used for the position that needs change the transmission axial direction, allows the angle between the connected part to change within the specific limits, and universal joint and transmission shaft combination are called card gear.The large scale industry fan can be tall and big working spaces such as factory and provides aeration-cooling, and this large scale industry fan has hanging, mounting type such as vertical, for ceiling fan; Because its flabellum is bigger, suspension height is higher, during installation; The angle of flabellum and swing arm is wayward, if flabellum is not in horizontal plane, countershaft is caused bigger wearing and tearing; Make fan life shorten, and cause potential safety hazard.In addition; The height in ventilation place differs, and working environment is had nothing in common with each other, and the setting height(from bottom) of fan is required also to change; This just need regulate the hanging stick length of overhead fan, and it is a kind of way eaily that the hanging stick of use different length specification connects combination.
The model utility content
The purpose of the utility model provides a kind of body of rod and connects universal joint, conveniently the angle between the body of rod is regulated.
The utility model is that the technological scheme that its technical problem of solution is adopted is,
A kind of body of rod connects universal joint, includes at least one pair of connecting rod, also includes flanged plate; The end of adjacent connecting rod connects mutually through this flanged plate; The flanged plate middle part is provided with a countershaft, and the end of flanged plate and adjacent connecting rod is passed in rotating shaft, and connecting rod can be around this rotating shaft rotation;
Particularly, said flanged plate two ends are respectively equipped with arcuate socket, are provided with limited bolt in each connecting rod, and the head end of limited bolt stretches out outside the arcuate socket; Said connecting rod is a hollow square tube shape; Said flanged plate has stiffened edge, and this stiffened edge vertically is provided with along flanged plate, and to the outer lateral buckling of flanged plate; Said flanged plate is provided with a pair of, lays respectively at the connecting rod both sides.
The advantage of the utility model is that this universal joint couples together adjacent connecting rod through flanged plate, and each connecting rod can rotate alone around the shaft; Thereby the angle between the adjacent connecting rod is adjusted, and at the flanged plate two ends arcuate socket is set, and stop screw slides in arcuate socket; Transformation range to the connecting rod angle limits; It is simple in structure, and assembling easily, and is easy to use.
Description of drawings
Fig. 1 is the structural representation that the body of rod of the utility model proposition connects universal joint.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
As shown in Figure 1; The body of rod that the utility model proposes connects universal joint and includes pair of links 100; The end that also includes 200, two connecting rods 100 of flanged plate connects mutually through flanged plate 200, and flanged plate 200 middle parts are provided with a countershaft 210; The end of flanged plate 200 and connecting rod 100 is passed in rotating shaft 210, connecting rod 100 210 rotations around the shaft; Flanged plate 200 two ends are respectively equipped with arcuate socket 220, are provided with limited bolt 110 in the connecting rod 100, and the head end of limited bolt 110 stretches out outside the arcuate socket 220; Connecting rod 100 is a hollow square tube shape; Flanged plate 200 has stiffened edge 230, and stiffened edge 230 is along vertical setting of flanged plate 200, and to the outer lateral buckling of flanged plate 200; Flanged plate 200 is provided with a pair of, lays respectively at the both sides of connecting rod 100.
This universal joint couples together adjacent connecting rod through flanged plate, and each connecting rod can rotate alone around the shaft, thereby the angle between the adjacent connecting rod is adjusted; And arcuate socket is set at the flanged plate two ends; Stop screw slides in arcuate socket, and the transformation range of connecting rod angle is limited, and it is simple in structure; Assembling easily, and is easy to use.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
