Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-3, the utility model discloses a bolt connection structure, including connecting box 1, grafting axle 2 and the camshaft 3 that has cam 31, the top of connecting box 1 is equipped with and supplies grafting axle 2 male butt joint hole 11, rotatable the installing in connecting box 1 of camshaft 3, the side of grafting axle 2 is equipped with first arc recess 21, and when grafting axle 2 inserted butt joint hole 11, camshaft 3 can make cam 31 card go into or withdraw from first arc recess 21 at the rotation in-process.

The utility model discloses a use is: at first with camshaft 3 rotate to the unclamping position, cam 31 does not enter into the region of butt joint hole 11 promptly, then insert grafting axle 2 from the butt joint hole 11 at connecting box 1 top to make the first arc recess 21 on the grafting axle 2 towards camshaft 3, rotate camshaft 3 again at last, cam 31 on the camshaft 3 can get into first arc recess 21, thereby realize the locking of grafting axle 2 and camshaft 3. When the plug shaft 2 is to be disassembled, the cam shaft 3 is rotated reversely to separate the cam 31 from the first arc-shaped groove 21.

In order to reduce the connection structure, the insertion shaft 2 can be made to be close to the camshaft 3 as much as possible, but in order to avoid interference, the second arc-shaped groove 32 is arranged on one side of the cam 31 far away from the protruding part, only when the second arc-shaped groove 32 faces the butt joint hole 11, the insertion shaft 2 can be smoothly inserted into the bottom of the butt joint hole 11, and when the camshaft 3 is rotated, the cam 31 can enter the first arc-shaped groove 21 more quickly, so that the assembly efficiency is improved.

For the arrangement form of the plug shaft 2 and the camshaft 3, the plug shaft 2 and the camshaft 3 can be locked through the cam 31 as long as the plug shaft and the camshaft are arranged in a crossed mode, but the preferred scheme is that the axial direction of the camshaft 3 is perpendicular to the axial direction of the butt joint hole 11, so that the first arc-shaped groove 21 and the second arc-shaped groove 32 can be processed better, the locking acting force of the cam 31 on the plug shaft 2 can be guaranteed to be parallel to the plug shaft 2, and the plug shaft 2 is prevented from being deformed due to repeated use.

Usually, during the assembly of the module to the module, the plug-in shaft 2 and the connection box 1 are fixed relative to each other, so that it is ensured that the first arcuate recess 21 is opposite the camshaft 3 during the plug-in process. For some connection points where there is no requirement or limitation on the assembly angle, in order to facilitate the first arc-shaped groove 21 to always face the camshaft 3, the first arc-shaped groove 21 may be provided as a ring-shaped groove arranged along the circumferential direction of the plug shaft 2. This enables the cam 31 to lock the plug shaft 2 regardless of how it is inserted into the mating hole 11.

Further, in order to conveniently judge the rotation degree of the camshaft 3 in the disassembly process and then take out the plug shaft 2, a spring 4 is arranged at the bottom of the butt hole 11 of the connecting box 1. During the installation, the spiale 2 compresses spring 4 in butt joint hole 11 bottom, and during the dismantlement, after cam 31 breaks away from first arc recess 21, the spiale 2 can be ejecting by spring 4 to conveniently take out spiale 2.

For other configurations, the present application also provides some of the following preferences. In order to facilitate the rotation of the camshaft 3, two ends of the camshaft 3 are rotatably connected with the connecting box 1 through bearings 5. In order to avoid the mistake to bump and lead to camshaft 3 not hard up, the one end of camshaft 3 is equipped with detachable handle 6, only just inserts handle 6 at the dismouting in-process, just takes off handle 6 immediately after accomplishing the dismouting to avoid handle 6 to influence the butt joint module, also avoid bumping because of the mistake and lead to camshaft 3 not hard up.
