Abstract
A kind of link, is characterized in that: comprise the tetragonal body joint coaxially connected successively, cylindrical transmission unit, the first cylinder connecting rod, the first threaded joints, the second cylinder connecting rod, the second threaded joints.The present invention adopts a cylinder-shaped link, utilizes tetragonal body and the mode be threaded, and connects three mechanical parts simultaneously, and it is high that parts connect precision, takes up room little.
Description
Technical field
The present invention relates to a kind of link, belong to field of mechanical technique.
Background technique
In the connection of mechanical part, adopt the mode connected between two often, although the structure of this Placement Placement and link is simple, connects accurate and the conditional occasion of spatial requirement in part requirement, often can not meet the connection request of parts.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of link, adopt a cylinder-shaped link, utilize tetragonal body and the mode be threaded, connect three mechanical parts simultaneously, it is high that parts connect precision, takes up room little.
For achieving the above object, the present invention is realized by following technological means:
A kind of link, is characterized in that: comprise the tetragonal body joint coaxially connected successively, cylindrical transmission unit, the first cylinder connecting rod, the first threaded joints, the second cylinder connecting rod, the second threaded joints.
Further:
Described a kind of link, is characterized in that: the cross section of described tetragonal body joint is positive square.
Described a kind of link, is characterized in that: the diameter of described cylindrical transmission unit is the twice of the positive square length of side.
Described a kind of link, is characterized in that: described cylindrical transmission unit diameter is greater than the diameter of the first cylinder connecting rod.
Described a kind of link, is characterized in that: the diameter of described first cylinder connecting rod is greater than the external diameter of the first threaded joints.
Described a kind of link, is characterized in that: the length of described second threaded joints is the twice of the first threaded joints.
Described a kind of link, is characterized in that: the diameter of described second cylinder connecting rod equals the external diameter of described first threaded joints, the second threaded joints.
Described a kind of link, is characterized in that: the diameter of described first cylinder connecting rod is 2/3rds of cylindrical transmission unit diameter.
Described a kind of link, is characterized in that: the screw thread of described first threaded joints, the second threaded joints is self-locking thread.
The invention has the beneficial effects as follows: the present invention adopts a cylinder-shaped link, utilize tetragonal body and the mode be threaded, connect three mechanical parts, it is high that parts connect precision, takes up room little simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention, and Fig. 2 is the A direction view of Fig. 1.
Embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
A kind of link, is characterized in that: comprise the tetragonal body joint 1, cylindrical transmission unit 2, first cylinder connecting rod 3, first threaded joints 4, second cylinder connecting rod 5, second threaded joints 6 that coaxially connect successively.
Further:
Described a kind of link, is characterized in that: the cross section of described tetragonal body joint 1 is positive square.
Be convenient to manufacture, save manufacture cost.
Described a kind of link, is characterized in that: the diameter of described cylindrical transmission unit 2 is the twice of the positive square length of side.
Described a kind of link, is characterized in that: described cylindrical transmission unit 2 diameter is greater than the diameter of the first cylinder connecting rod 3.
Cylindrical transmission unit 2 diameter is large, and transmission can be avoided to disturb.
Described a kind of link, is characterized in that: the diameter of described first cylinder connecting rod 3 is greater than the external diameter of the first threaded joints 4.
First cylinder connecting rod 3 diameter is large, can carry out end restriction to connected piece.
Described a kind of link, is characterized in that: the length of described second threaded joints 6 is the twice of the first threaded joints 4.
Second threaded joints 6 is long, and one is that the end lacking the first cylinder connecting rod 3 pairs of connected pieces limits the first cylinder connecting rod 3, secondly where necessary, can carry out two ends screw restriction to connected piece.
Described a kind of link, is characterized in that: the diameter of described second cylinder connecting rod 5 equals the external diameter of described first threaded joints 4, second threaded joints 6.
Diameter is identical, is convenient to manufacture.
Described a kind of link, is characterized in that: the diameter of described first cylinder connecting rod 3 is 2/3rds of cylindrical transmission unit 2 diameter.
Reduce the interference to transmission.
Described a kind of link, is characterized in that: the screw thread of described first threaded joints 4, second threaded joints 6 is self-locking thread.
Increase the reliability connected.
More than show and describe basic principle of the present invention, major character and advantage.The technician of the industry should understand; the design is not restricted to the described embodiments; the principle that the design is just described described in above-described embodiment and specification; under the prerequisite not departing from the design's spirit and scope; the design also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the design.The claimed scope of the design is defined by appending claims and equivalent thereof.
