Example 2
This embodiment is a specific explanation of the stopper pin 6 in embodiment 1.
When the detachable connection is in a tensioned state, the limiting pin is radially pulled, and when axial dislocation is generated between the mounting cylinder 5 and the straight bar 7, the limiting pin can deform at the direct part of the mounting cylinder 5 and the straight bar: the part of the limiting pin matched with the straight strip moves outwards along the straight strip, and the part of the limiting pin matched with the mounting cylinder 5 keeps the mounting cylinder 5 still; this just leads to when dismantling, and the spacer pin both ends and middle part disalignment, and both the spacer pin middle part is not coaxial with the hole that supplies the spacer pin to run through on the installation section of thick bamboo 5, leads to the spacer pin middle part can't pass the hole that supplies the spacer pin to run through on the installation section of thick bamboo 5 smoothly, and the spacer pin can't take off from the installation section of thick bamboo 5 smoothly. Based on the problem, the invention is designed as follows: the limiting pin 6 comprises a pin shaft 10 and a pin sleeve 11 which is sleeved on the pin shaft 10, the pin shaft 10 is in clearance fit with the pin sleeve 11, and one end of each of the pin shaft 10 and the pin sleeve 11 penetrates through the side wall of one side of the installation cylinder 5 and then sequentially penetrates through the through hole 9 of one straight strip 7 and the through hole 9 of the other straight strip 7 and then penetrates out of the side wall of the other side of the installation cylinder 5. In this way, when an axial misalignment occurs between the mounting cylinder 5 and the straight bars 7, the pin bushes 11 are deformed: the two ends and the middle of the pin shaft are not coaxial, the pin shaft 10 is in clearance fit with the pin sleeve 11, the pin shaft 10 is not deformed or deformed, the pin shaft 10 can be withdrawn more easily compared with the whole pin shaft, then the pin sleeve 10 is hollow, the pin sleeve 10 is pulled forcefully to be extruded and deformed inwards, and the pin sleeve is taken down from the mounting cylinder 5.
The limiting pin designed by the invention can ensure the overall strength through the matching of the pin shaft 10 and the pin sleeve 11, and can be detached one by one after later-stage deformation, so that the convenience and the possibility of detachment are improved, and the later-stage maintenance cost is reduced.
Further, a pull ring 12 is connected to one end of the pin 10. The pull ring 12 facilitates the pin 10.
Furthermore, one end of the inner wall of the pin sleeve 11 is provided with 0.5-2 circles of threads A, and the pin shaft 10 is provided with threads B matched with the threads A in a threaded mode.
For convenience in assembly, the pin shaft 10 is prevented from slipping off the pin sleeve 11, preferably in threaded connection, and for convenience in disassembly, the number of effective connection turns of the direct threaded connection part is preferably 0.5-2.
Further, springs 13 are arranged on the straight bars 7 and the bottom of the installation cylinder 5 matched with the straight bars 7, and two ends of each spring 13 are respectively contacted with the bottom of the installation cylinder and the tail end of each straight bar 7.
Further, the spring 13 is a disc spring to prevent vertical shaking caused by an axial fit clearance in the connection unit.
Example 3
The present embodiment is an embodiment of the straight bar 7 based on the above embodiments.
The cross section of the straight strip 7 is semicircular, in the connecting unit, the plane side wall of the straight strip 7 of the left single-side part is contacted with the plane side wall of the straight strip 7 of the right single-side part, so that the straight strips 7 are spliced to form a shaft body with a circular cross section, and the diameter of a central hole of the mounting cylinder 5 is consistent with the diameter of the shaft body.
In connection with the present invention, it is preferable that the straight bars 7 are provided with screw threads on the outer cylindrical side wall, and in each connection unit, when the straight bars 7 are assembled to form a shaft body with a circular cross section, the screw threads on the straight bars form a complete screw thread, the inner hole of the mounting cylinder 5 is a threaded hole, and the shaft body is inserted into the mounting cylinder 5 and is in threaded connection with the mounting cylinder. The screw thread of upper and lower connecting element revolves to opposite directions, and when its upper and lower overall arrangement like this, can all rotate towards one direction and be screwed up, and another direction is slack. When the threaded connection is adopted, the structure stability is better, the deformation of the limiting pin can be effectively avoided, and meanwhile, when the threaded connection is adopted, the upper and lower unilateral components need to rotate simultaneously in consideration of disassembly.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
