Problems solved by technology
[0004] In the actual application process, the movement of some mechanisms requires a certain range of displacement in the axial direction of the connecting rod, and a certain amount of movement in other directions at the same time, which requires the connecting rod to be able to move both in the axial direction and in other directions. There is a certain amount of movement margin, and the traditional connecting rod cannot meet the above requirements

Embodiment Construction
[0029] The above objectives of the present invention are achieved through the following technical solutions, which are described as follows with reference to the drawings.
[0030] Refer to figure 1 , 2 , A buffered connecting rod that can be freely retractable in the axial direction and can be locked and fixed. The connecting rod includes a connecting rod support 1, a pin shaft 2, an articulated bearing 3, a core shaft end cover locking sleeve 4, and a core shaft end Cover connecting sleeve 5, buffer outer tube 6, mandrel 7, nylon sleeve I 8, rubber metal sheet buffer 9, buffer lock nut 10 and nylon sleeve II 11. The inner wall of the rubber sheet metal buffer 9 and the core shaft 7 are connected by friction pairs and axially locked by the buffer lock nut 10. The outer wall of the rubber sheet metal buffer 9 matches the inner wall of the buffer outer tube 6 and can slide axially. The mandrel end cover locking sleeve 4 and the mandrel end cover connecting sleeve 5 are respectivel...

The invention relates to a connecting rod, in particular to a buffer type connecting rod capable of axially and freely extending and retracting and being locked and fixed. The buffer type connecting rod mainly comprises a mandrel and two connecting rod supports, wherein the mandrel is a stepped shaft and is provided with a mandrel end cover lock sleeve, a rubber metal sheet buffer and a mandrel end cover connecting sleeve; the mandrel end cover lock sleeve and the mandrel end cover connecting sleeve are fixedly connected to flanges at both ends of an outer sleeve of the buffer through bolts respectively; the rubber metal sheet buffer is axially locked by a buffer lock nut and is in slide fit with the outer sleeve of the buffer; one connecting rod support is in threaded connection with one end of the mandrel through an oscillating bearing, and the other connecting rod support is in threaded connection with the mandrel end cover connecting sleeve through another oscillating bearing; and the two oscillating bearings are connected with the two connecting rod supports through pins respectively. The connecting rod can be freely extended and retracted in a certain axial range, and has certain moving allowance in other directions so as to meet various functional requirements.
Description
Technical field [0001] The invention relates to a connecting rod, in particular to a connecting rod with a buffer which can be freely retracted and locked in an axial direction. Background technique [0002] The connecting rod mechanism is composed of several components connected with low pairs (rotation pair, moving pair, spherical pair, ball pin pair, cylindrical pair, screw pair, etc.). Linkage mechanisms are often used for rigid body guidance, to achieve known motion laws or known trajectories. The connecting rod used for the auxiliary support of the mechanical structure can improve the support rigidity of the mechanical frame and maintain the balance of the moving part I. The basic structure of the supporting connecting rod is that the middle section is a fixed-length or length-adjustable rod-shaped structure. The two ends of the connecting rod are respectively fixedly connected to the two rigid bodies that need to be restrained by joint bearings and pin shafts to assist in...
