Abstract
The invention discloses a telescopic universal joint which relates to the field of electronic machinery. The invention specifically relates to a telescopic universal joint. The telescopic universal joint comprises an inner rod of a telescopic rod, an outer rod of a telescopic rod, flanges, bolts, an integration sleeve, a universal shaft, a cushion block, a spherical pin, a bulb joint and cover plates, wherein a flange and a cover plate are firmly installed on two ends of the integration sleeve by bolts respectively; the middle part outside the flange is firmly connected to the inner rod of the telescopic rod; the outer rod of the telescopic rod is disposed on the outer circle of the inner rod of the telescopic rod; the bulb joint is disposed in a center hole of the integration sleeve; the cushion block is disposed in the center hole of the integration sleeve between the bulb joint and the flange; the universal shaft passes through center holes of the cover plates and are firmly connected to the bulb joint; and a spherical pin perpendicular to the universal shaft is firmly installed on the outer circle of the bulb joint. The telescopic universal joint disclosed by the invention has the beneficial effects that the length can be changed at will; axis power output becomes stable; the structure is novel; and the telescopic universal joint is safe, reliable, convenient, practical, highly compatible, firm and durable.
Description
Technical field:
The present invention relates to electric mechanical field, be specifically related to extension type universal joint.
Background technology:
Universal joint is the parts realizing the transmission of varied angle power, is used for needing to change transmission axis side
To position, it is the vitals of the universal driving device of automobile driving system.Universal joint with
Power transmission shaft combines, referred to as card gear.
Traditional universal joint typically uses regular length, uses poor compatibility, safety relatively low,
It is unfavorable for uniform and stable axle power output.
Summary of the invention:
Present invention aims to defect and the deficiency of prior art, it is provided that a kind of structure letter
Extension type universal joint single, reasonable in design, easy to use, it can realize freely becoming of length
Changing, stablize the output of axle power, novel structure, safe and reliable, convenient and practical, compatibility is wide,
Sturdy and durable.
In order to solve the problem existing for background technology, the technical solution used in the present invention is: it
Including bar in expansion link, the outer bar of expansion link, flange, bolt, combined cover, universal drive shaft, cushion block,
Ball pin, bulb joint, cover plate；Two ends bolt at combined cover is respectively mounted fixes one
Flange and cover plate, fix, bar in expansion link outside middle the connection with bar in expansion link of flange
Outer ring, be provided with the outer bar of expansion link, in the interstitial hole of combined cover, be provided with bulb joint,
Being provided with cushion block in combined cover interstitial hole between bulb joint and flange, universal drive shaft is through lid
Plate interstitial hole is connected fixing with bulb joint, installs at bulb joint cylindrical and fixes one with universal
The ball pin that axle is perpendicular.
After using said structure, present invention have the beneficial effect that it can realize freely changing of length,
Stablizing the output of axle power, novel structure, safe and reliable, convenient and practical, compatibility is wide, hard
Gu it is durable.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention.
Description of reference numerals: the outer bar 2 of bar 1 in expansion link, expansion link, flange 3, bolt 4,
Combined cover 5, universal drive shaft 6, cushion block 7, ball pin 8, bulb joint 9, cover plate 10.
Detailed description of the invention:
The present invention is further illustrated below in conjunction with the accompanying drawings.
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with
The drawings and the specific embodiments, are further elaborated to the present invention.Should be appreciated that this
Detailed description of the invention described by place only in order to explain the present invention, is not intended to limit the present invention.
As it is shown in figure 1, this detailed description of the invention adopts the following technical scheme that it includes expansion link
Interior bar 1, expansion link outer bar 2, flange 3, bolt 4, combined cover 5, universal drive shaft 6, cushion block
7, ball pin 8, bulb joint 9, cover plate 10；At the two ends of combined cover 5 with 4 points of bolt
An Zhuan not fix a flange 3 and cover plate 10, outside middle and the bar 1 in expansion link of flange 3
Connect fixing, the outer ring of bar 1 in expansion link, it is provided with the outer bar 2 of expansion link, at combined cover
Bulb joint 9 it is provided with, the combination between bulb joint 9 and flange 3 in the interstitial hole of 5
Being provided with cushion block 7 in overlapping 5 interstitial holes, universal drive shaft 6 closes through cover plate 10 interstitial hole with bulb
Joint 9 connection is fixing, bulb joint 9 cylindrical install fix one perpendicular with universal drive shaft 6
Ball pin 8.
Cooperation by the outer bar 2 of bar in expansion link 1 and expansion link, it is achieved universal joint scalable
Function, in can dragging expansion link in use according to actual needs, bar 1 is to adjust length, uses
Convenient, output is stablized.
This detailed description of the invention can realize freely changing of length, stablizes the output of axle power, knot
Structure is novel, safe and reliable, convenient and practical, compatible wide, sturdy and durable.
The above, only in order to technical scheme to be described and unrestricted, this area is common
Other amendment or equivalent that technical scheme is made by technical staff, as long as not
Depart from the spirit and scope of technical solution of the present invention, the claim model in the present invention all should be contained
In the middle of enclosing.
