Detailed Description

The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments described in the present disclosure, all other embodiments obtained by a person skilled in the art without creative efforts are within the scope of the present disclosure.

The first embodiment is as follows:

as shown in fig. 1 to 5, the invisible connecting piece comprises an inserting piece 1 and a locking piece 2, wherein the outer end surfaces of the inserting piece 1 and the locking piece 2 are both provided with threads, a U-shaped groove is formed in the locking piece 2, a locking device is arranged in the U-shaped groove, a protruding rod 3 is arranged at the front end of the inserting piece 1, and the protruding rod 3 is inserted into the U-shaped groove under the action of external force and is locked by the locking device.

The locking device comprises an extruding part, a spring 6 and an extruding ring 7, wherein the spring 6 is abutted against the extruding ring 7, and the extruding ring 7 is arranged between the spring 6 and the extruding part.

The U-shaped groove is also internally provided with a bottom plate 5, the bottom plate 5 is arranged at the bottom end of the U-shaped groove, and the spring 6 is abutted against the bottom plate 5.

The side surface of the convex rod 3 is provided with an anti-skid groove corresponding to the extrusion piece.

The extrusion is a steel ball 4.

During the use, on screwing in or inserting the plate that needs to be connected respectively with inserter 1 and hasp piece 2, insert the U-shaped inslot of hasp piece 2 with the nose bar 3 of inserter 1, nose bar 3 extrudees steel ball 4, steel ball 4 atress slides to bottom plate 5 direction, when nose bar 3 inserts the bottom, extrusion ring 7 extrudees steel ball 4 under the effect of spring 6 elasticity, steel ball 4 atress slides to the antiskid groove department of nose bar 3, apply radial pressure to nose bar 3, make nose bar 3 lock at the U-shaped inslot, thereby realize the connection of two plates, when needing to demolish, act on hasp piece 2 bottom with the strong magnet, extrusion ring 7 and steel ball 4 receive magnetic force to attract to remove to bottom plate 5 direction, the auto-lock phenomenon disappears, nose bar 3 can easily remove this moment.

Example two:

as shown in fig. 6, the difference between the second embodiment and the first embodiment is that the extrusion member is a wedge-shaped block 8, the extrusion member may also be an extrusion object such as a rectangular block or an oval bead, the wedge-shaped block 8 and the extrusion ring 7 are both made of materials that can be attracted by a magnet, the wedge-shaped block 8 is connected to the extrusion ring 7, after the protruding rod 3 is inserted into the U-shaped groove, the protruding rod 3 extrudes the wedge-shaped block 8, so that the wedge-shaped block and the extrusion ring 7 move together toward the bottom plate 5, after the protruding rod 3 is inserted to the bottom, the wedge-shaped block 8 and the extrusion ring 7 move downward under the action of the spring 6, and the wedge-shaped block 8 extrudes the protruding rod 3, thereby realizing self-locking.
