Description
Technical Field
The utility model belongs to the field of machinery, concretely relates to connecting rod.
Background
The traditional shaft and the shaft are usually fixed by welding, if the welding is not good, the connection dislocation and other conditions are easy to occur, and the relative position is locked after the welding, so that the shaft cannot be detached or re-reinforced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defect of prior art, the utility model aims to provide a connecting rod can effectively reduce because of the dislocation problem and the dismantlement problem that the welding is bad to lead to.
A connecting rod, comprising:
the connecting rod body of rod, first semicircular groove has been seted up to the one end of the body of rod, the other end of the body of rod is equipped with the second semicircular groove, first semicircular groove is keeping away from one side of the body of rod is equipped with first semicircular groove, the second semicircular groove is keeping away from one side of the body of rod is equipped with second semicircular groove, first semicircular groove and first semicircular groove first half groove registrate and form first annular connecting portion, second semicircular groove and second semicircular groove second half groove registrate and form second annular connecting portion jointly, the body of rod is close to a screw thread through-hole has been seted up respectively to one side of first, second annular connecting portion, supplies threaded fastener to pass, first, second annular connecting portion are close to one side vertical inside opening of the body of rod.
In a preferred embodiment of the present invention, the annular radius of the first annular connecting portion is larger than the annular radius of the second annular connecting portion.
In a preferred embodiment of the present invention, the first semicircular groove has an oil hole opened along a vertical axial direction.
The beneficial effects of the utility model reside in that:
the utility model provides a connecting rod can effectively reduce because of dislocation problem and the dismantlement problem that the welding is bad leads to.

Detailed Description
The structure and working principle of the present invention are further illustrated by the following examples:
referring to fig. 1-3, there is shown a connector rod comprising:
the connecting rod body of rod 100 of the narrow one end of the wide one end of one end, first semicircular groove 110 has been seted up to the wide end of the body of rod, second semicircular groove 120 has been seted up to the narrow end of the body of rod, first semicircular groove 110 is equipped with first semicircular groove 210 in one side of keeping away from the body of rod 100, second semicircular groove 120 is equipped with second semicircular groove 310 in one side of keeping away from the body of rod 100.
The first semicircular groove 110 and the first semicircular groove upper half groove 210 are jointly sleeved to form a first annular connecting part 200, and the second semicircular groove 120 and the second semicircular groove lower half groove 310 are jointly sleeved to form a second annular connecting part 300.
In order to further fasten the shaft after the shaft (not shown) is connected, threaded through holes 130 and 140 are respectively formed at the sides of the rod body 100 close to the first and second annular connecting portions 200 and 300 for a threaded fastener (not shown) to pass through, and the sides of the first and second annular connecting portions 200 and 300 close to the rod body 100 are vertically and inwardly opened to form a first contact portion 220 and a second contact portion 320.
In order to lubricate the connecting rod in use, an oil hole 211 is opened in the first semicircular groove upper half 210 in a vertical axial direction.
Because the structure is adopted, the utility model discloses a theory of operation lies in:
the first shaft is first inserted into the first annular connecting portion 200, and the second shaft is then inserted into the second annular connecting portion 300, and the order of insertion may be changed.
The threaded fasteners are then passed through the threaded through holes 130, 140 and then tightened so that the threads on the threaded fasteners are in compressive contact with the first and second shafts.
After the use, the first shaft and the second shaft can be detached after the threaded fastener is loosened.
Claims (3)
