Description
Technical field
The invention belongs to the auxiliary equipment of transmission structure, more particularly to a kind of drive link for connecting two drive links
Joint.
Background technology
In mechanical engineering, power is carried out into Long Distant Transmit by means of gear train, belt, chain, power transmission shaft etc. often.Its
In, transmission shaft driven is a kind of kind of drive with unique advantage.Transmission shaft driven has simple structure, rigidity good, motor-driven
Property strong, mechanical efficiency is high, adaptability and the features such as good reliability, it is convenient to realize the power transmission of large span.Should in engineering
With in, power transmission shaft can be made to depart from immobilizing foundation bearing, be arranged in hollow tube wall by bearing, made moveable hand-held
Drive link.The power of miniature gasoline engine is exactly passed to 2 meters using drive link and is opened by the long handle chain saw that gardens department uses at present
Outer chain saw head.Garden landscape trees can be carried out pruning and play the finishing of leaf by this long handle chain saw with lengthening drive link
Operation.But for it is similar using drive link is lengthened realizing the engineer applied of remote power transmission, exist one it is common
Problem：It is exactly their work when the plant equipment similar to long handle horticultural branching machine, when becoming commodity and being supplied to user
Make length to be just determined, it is impossible to need to increase or decrease the length of drive link according to real work, so that machine work neck
Domain is restricted, and weakens motility and the adaptability of plant equipment work.Reason be there is presently no it is a kind of more simple and practical
Jointing easily drive link can be connected section by section.
The content of the invention
It is an object of the invention to provide one kind is in portable tending of woods delimbing brush cutter and its similar mechanical engineering
The simple structure of middle application, highly versatile, good reliability, the drive rod joint with lenticular attachment structure of easy care.
To achieve these goals, present invention employs technical scheme below：
A kind of drive rod joint, is two drive links（Such as drive link A and drive link B）Coupling part；Which is mainly by setting
Put and constitute in the convex spindle nose of power transmission shaft A ends, the matrix spindle nose for being arranged on power transmission shaft B ends and branch sleeve；Described is convex
Profile shaft head is mutually agreed with matrix spindle nose；Described branch sleeve is provided with female thread；In hollow pipe A ends and hollow pipe B ends
Outer surface is respectively equipped with external screw thread；The two ends of described branch sleeve are threadedly coupled with hollow pipe A, hollow pipe B respectively.
The drive rod joint simple structure of the present invention, highly versatile, good reliability and disassembling operations are simple, using the present invention
After the connected mode of drive rod joint, can carry out according to demand increasing and decreasing drive link joint number, to change the entire length of drive link,
Improve motility and adaptability that plant equipment realizes remote power transmission.
Used as further illustrating for the present invention, above-described convex spindle nose is integrated manufacture with power transmission shaft A；Described is recessed
Profile shaft head is integrated manufacture with power transmission shaft B.Using integrally manufactured, the reliability of connection can be improved, be conducive to the transmission of power,
Be conducive to processing and manufacturing and installation simultaneously.
As further illustrating for the present invention, after above-described convex spindle nose and the connection of matrix spindle nose, flat recess type is formed
Lenticular attachment structure forms the lenticular attachment structure of Phillips-type.Using flat recess type（Or Phillips-type）It is lenticular
Connection, makes simple structure, reliable, easy to assemble.
As further illustrating for the present invention, the external thread length of above-described hollow pipe A ends and hollow pipe B ends
It is the half of branch sleeve length.
Used as further illustrating for the present invention, to be taken in, branch sleeve screws in the hollow pipe B ends for having matrix spindle nose one end
The external screw thread end when, the other end of branch sleeve is concordant with matrix spindle nose.
Used as further illustrating for the present invention, the above-described power transmission shaft A with convex spindle nose is installed in hollow pipe A
When finishing, described convex spindle nose exposes about 10mm outside hollow pipe end.Outside slightly protruding, beneficial to convex spindle nose and matrix spindle nose
Centering during connection.
Used as further illustrating for the present invention, above-described power transmission shaft A and power transmission shaft B passes through bearing and bearing rib respectively
Circle is installed in hollow pipe A, the inside of hollow pipe B.
The installation connection procedure of the present invention：Branch sleeve is screwed in into connected drive link B first there is spill spindle nose end
The external screw thread of hollow pipe B ends, till screwing.Then the convex spindle nose of connected drive link A is inserted the spill axle of drive link B
10mm in head, then take advantage of a situation by the female thread for screwing into branch sleeve of the hollow pipe A ends of drive link A, till screwing.Pass
Lever A is connected with drive link B and finishes.
Advantages of the present invention：
1. form and the lenticular connection of the on all four power transmission shaft of specification are adopted between each running part of plant equipment
Structure is attached, and makes have good assembling interchangeability between each part, and disassembly and assembly is convenient and simple, improves plant equipment
The motility of work and adaptability.
2. power transmission shaft is fixed in hollow pipe by bearing, and one end of power transmission shaft is designed as convex, and the other end is then designed as
Matrix, and for same specifications design；If the length increased by drive link, the concavo-convex relationship of drive link shaft end need to be only pressed, will
Each section power transmission shaft is sequentially connected.
3. present configuration is simple, highly versatile, good compatibility, manufacture easy to process and dismounting are safeguarded.
