Abstract
The invention relates to a telescopic connecting rod structure. The structure comprises a thread rod (1), a hexagonal nut (2), a stop gasket (3), a sleeve (4), a connecting rod (5), a left-handed nut (6), a left-handed thread rod (7), a joint bearing (8) and a bearing inner sleeve (9). Right-handed and left-handed internal threads are arranged at two ends of the connecting rod (5), and are respectively connected with the thread rod (1) and the left-handed thread rod (7). The joint bearing (8) is mounted in the thread rod (1) and the left-handed thread rod (7); the bearing inner sleeve (9) is mounted in the joint bearing (8); and the joint bearing (8) is connected with a connected part through the bearing inner sleeve (9). The thread rod (1) and the left-handed thread rod (7) are kept immovable; and the connecting rod (5) rotates to randomly adjust the length of the connecting rod structure. The structure is simple in composition and convenient for installation, can freely adjust the length of the connecting rod, can be used for fixed length connection and non-fixed length connection, and improves the connecting rod generality.
Description
Technical field
The present invention relates to a kind of bar linkage structure, the telescopic connecting rod structure of more particularly, to a kind of adjustable length.
Background technology
Connecting rod is very universal in field of mechanical technique application, and in frame for movement, it plays transmitting movement, the work of transmission power
With.In different structures, the length of connecting rod is also different, and mounting means is also different, in different structures,
It is accomplished by designing different connecting rods, the type so allowing for connecting rod is varied, both increased the workload of designer,
Increased the cost of production.
Content of the invention
It is an object of the invention to provide a kind of telescopic connecting rod structure of adjustable length, the application realizing connecting rod is general
Change.
The technical solution of the present invention：A kind of extension type bar linkage structure, including threaded rod, hex nut, stop pad
Circle, sleeve, connecting rod, left-handed nut, left hand thread bar, oscillating bearing and bearing inner sleeve.Described threaded rod is arranged on even
The right-handed thread end of adapter, with the locking of hex nut, stop washer and sleeve.Described left hand thread bar is arranged on connecting tube
Left hand thread end, with the locking of left-handed nut, stop washer and sleeve.Bearing inner sleeve is arranged in oscillating bearing, and oscillating bearing
It is arranged in threaded rod and left hand thread bar, is connected with connected component by bearing inner sleeve, connecting rod two ends are cone structure,
Have cross recess, when coordinating with sleeve, energy collet threaded is locking.The inner surface being inserted in the sleeve at connecting rod two ends respectively is also cone
Face structure.By keeping threaded rod and left hand thread bar motionless, rotate connecting rod, can arbitrarily adjust the length of bar linkage structure.
Additionally, the cone angle of sleeve interior surface, the conical surface at connecting rod two ends is 5 °～10 °, and sleeve interior surface cone angle is bigger
Cone angle in connecting rod two ends.
Beneficial effect of the present invention：The extension type bar linkage structure of the present invention is keeping threaded rod and left hand thread bar motionless
In the case of, by rotating connecting rod, arbitrarily adjusting the length of bar linkage structure, thus realizing the application generalization of connecting rod, reducing
The species of connecting rod, increases the versatility of connecting rod.
Additionally, application extension type bar linkage structure, the design accuracy of associated components can be substantially reduced, reduce production cost,
Improve production efficiency.

Specific embodiment
Below with reference to the accompanying drawings, in conjunction with specific embodiment, the present invention is described in further detail.
Fig. 1 is the extension type bar linkage structure schematic diagram of the present invention.Fig. 2 is the set of the extension type bar linkage structure of the present invention
Cylinder 4 and the partial schematic diagram of connecting rod 5.As illustrated, the extension type bar linkage structure of the present invention includes threaded rod 1, hexagonal spiral shell
Female 2, stop washer 3, sleeve 4, connecting rod 5, left-handed nut 6, left hand thread bar 7, oscillating bearing 8 and bearing inner sleeve 9.Described
The two ends of connecting rod 5 be provided with dextrorotation and levogyrate inner thread, connection screw thread bar 1 and left hand thread bar 7 respectively.Threaded rod 1 is installed
At the right-handed thread end of connecting tube 5, locked with hex nut 2, stop washer 3 and sleeve 4.Described left hand thread bar 7 is installed
At the left hand thread end of connecting tube 5, locked with left-handed nut 6, stop washer 3 and sleeve 4.Bearing inner sleeve 9 is arranged on joint shaft
Hold in 8, and oscillating bearing 8 is arranged in threaded rod 1 and left hand thread bar 7, be connected with connected component.Connecting rod 5 is provided with
Draw-in groove, keeps threaded rod 1 and left hand thread bar 7 motionless, blocks the draw-in groove in connecting rod 5 with spanner, rotate connecting rod 5, connecting rod
The length of structure can arbitrarily be adjusted.
Connecting rod 5 two ends have cross recess, and are designed to cone structure, and sleeve 4 inner surface is also designed to cone structure, set
Cylinder 4 inner surfacies, the cone angle of the conical surface at connecting rod 5 two ends are 5 °～10 °, and sleeve 4 inner surface cone angle is slightly larger than connecting rod 5 two ends
Cone angle.In present embodiment, the frustoconical bevel angle of sleeve 4 inner surface is 8 °.Sleeve 4 is inserted in the two ends of connecting rod 5, can make connection
Bar 5 two ends external diameter shrinks, and cone angle becomes big, thus collet threaded bar 1 and left hand thread bar 7, plays the locking effect of locking.
