Detailed Description
Example one
Referring to fig. 1-3, a locking structure for a threaded telescopic connecting rod includes a first connecting rod 1 and a second connecting rod 2, wherein one end of the first connecting rod 1 is provided with a threaded inner hole 101, and the side wall of the second connecting rod 2 is provided with an external thread matched with the threaded inner hole 101, i.e. the second connecting rod 2 can be screwed in the first connecting rod 1 by matching the external thread with the threaded inner hole 101, and the overall length of the first connecting rod 1 and the second connecting rod 2 can be changed by changing the screwing depth of the second connecting rod 2. In this embodiment, the side wall of one end of the second connecting rod 2, which is far away from the first connecting rod 1, is provided with the anti-slip pattern 202, and the anti-slip pattern 202 is convenient for rotating the second connecting rod 2.
The locking nut 3 and the special-shaped stop washer 4 are sequentially sleeved on the second connecting rod 2 along the direction close to the first connecting rod 1, the locking nut 3 is connected with the external threads of the side wall of the second connecting rod 2, the side wall of the first connecting rod 1 is provided with a boss 102, and the boss 102, the locking nut 3 and the special-shaped stop washer 4 are all provided with a safety hole 5 through which a fuse (not shown) can pass. When the locking device is used, after the overall lengths of the first connecting rod 1 and the second connecting rod 2 are adjusted in place, the locking nut 3 is screwed down to enable the special-shaped stop washer 4 to be abutted to the end part of the first connecting rod 1, and then the first connecting rod 1, the special-shaped stop washer 4 and the locking nut 3 are stringed together through the fuse to form a whole, so that the axial displacement of the whole of the locking nut 3 and the special-shaped stop washer 4 relative to the first connecting rod 1 is limited.
The inner wall of the special-shaped stop washer 4 is provided with a clamping block 401, one end, close to the first connecting rod 1, of the second connecting rod 2 is provided with a clamping groove 201, the clamping groove 201 extends in the axial direction and is matched with the clamping block 401, and it is worth explaining that after the first connecting rod 1, the special-shaped stop washer 4 and the locking nut 3 are connected in series through a fuse to form a whole, the clamping block 401 is matched with the clamping groove 201 to limit the whole of the locking nut 3 and the special-shaped stop washer 4 to rotate circumferentially relative to the first connecting rod 1. This embodiment is through the rethread fuse after fixture block 401 on the dysmorphism locking washer 4 and the draw-in groove 201 cooperation on the second connecting rod 2 with first connecting rod 1, dysmorphism locking washer 4 and lock nut 3 three cluster together and form a whole promptly to the screw thread that prevents to connect first connecting rod 1 and second connecting rod 2 well is not hard up.
At least one side of dysmorphism locking gasket 4 is equipped with lug 402, and the axis of insurance hole 5 perpendicular to dysmorphism locking gasket 4's axis is worth explaining, so set up for it penetrates insurance hole 5 from the side of second connecting rod 2 when threading the fuse, and operating space is more sufficient, and operating space is not enough and the operation difficulty when avoiding the narrow and small operating space of screw thread telescopic link structure installation space. In this embodiment, two opposite sides of the shaped gasket 4 are respectively provided with a protrusion 402, that is, a connecting line of the two protrusions 402 passes through a center of the shaped gasket 4, and a fuse is more reliably connected after passing through the two protrusions 402.
The boss 102 on the side wall of the first connecting rod 1 is in a regular hexagon shape perpendicular to the axial section, so that the first connecting rod 1 can be kept fixed by clamping the boss 102 through a wrench tool when the second connecting rod 2 is rotated to adjust the overall length of the first connecting rod 1 and the second connecting rod 2. Further, the boss 102 and the fuse hole 5 of the lock nut 3 extend from one side surface to the other adjacent side surface, and the arrangement is convenient for more sufficient operation space when a fuse is penetrated, like the fuse hole 5 of the special-shaped stop washer 4.
Example two
Referring to fig. 4-5, the present embodiment provides an installation structure of a threaded telescopic connecting rod, including a threaded telescopic connecting rod locking structure provided in the first embodiment, and a connecting shaft 7 penetrating through installation holes in two side walls of a connecting part 200, a stopper 701 is disposed at one end of the connecting shaft 7 close to the inner side of the connecting part 200, a supporting shaft 702 is disposed on the stopper 701, assembly holes 6 matched with the supporting shaft 702 are disposed at one ends of a first connecting rod 1 and a second connecting rod 2 close to the adjacent connecting shaft 7, in the present embodiment, the assembly holes 6 on the second connecting rod 2 penetrate through the axial direction of the second connecting rod 2, that is, the second connecting rod 2 is in a sleeve shape, the assembly holes 6 on the first connecting rod 1 are communicated with the threaded inner hole 101, so that the first connecting rod 1 is also in a sleeve shape.
During the use, wear to establish in connecting part 200 both sides wall mounting hole with two connecting axles 7, put the flexible connecting rod anti loosening structure of screw thread that embodiment one provided between the both sides wall of connecting part 200 again, twist and move second connecting rod 2, make first connecting rod 1 and the whole length of second connecting rod 2 elongated, make first connecting rod 1 and second connecting rod 2 support the back on the lateral wall of connecting part 200 with adjacent dog 701, can screw up lock nut 3, rethread fuse is with first connecting rod 1, dysmorphism locking washer 4 and lock nut 3 three cluster together and lock between first connecting rod 1 and the second connecting rod 2.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
